Description

[0001] This application is a divisional application of the Chinese patent application with application number 2022222521608 filed on August 25, 2022 and entitled “Respiratory Therapy Accessories and Respiratory Therapy System”. Technical Field

[0002] The present disclosure relates to accessories for respiratory therapy and respiratory therapy systems including such accessories. More particularly, but not exclusively, the present disclosure relates to a respiratory therapy accessory configured to attach to a support and retain at least one respiratory therapy component. Background Art

[0003] Respiratory devices are used in a variety of settings, such as hospitals, healthcare facilities, inpatient care, palliative care, and home settings. For a range of respiratory applications, it is beneficial to humidify the respiratory gases supplied to a patient from a gas source. Humidifying the gases increases patient comfort, improves patient tolerance of treatment, and the humidified gases are less likely to dry out tissues of the patient's airway (e.g., nasal mucosa).

[0004] Respiratory therapy can be provided in several different forms, including at least invasive ventilation, non-invasive ventilation (NIV), and nasal high flow (NHF) therapy.

[0005] In the case of invasive ventilation therapy, humidified breathing gases are delivered to the patient through an invasive patient interface assembly that bypasses the patient's upper airway. The invasive patient interface assembly can be an intubating endotracheal tube or a tracheostomy tube. The gas source can be a ventilator that delivers pressurized gas to a humidifier through a "dry line" conduit. The humidifier heats and humidifies the gas, which is then transmitted to the patient interface assembly through an inspiratory conduit. Exhaled gases can be exhausted to the atmosphere (called a single-limb circuit) or returned to the ventilator (called a double-limb circuit) through an expiratory conduit that is fluidly connected to the inspiratory conduit and the invasive patient interface assembly by a Y-piece.

[0006] In the case of non-invasive ventilation (NIV) therapy, breathing gases are delivered to the patient's upper airway through a non-invasive patient interface assembly. The non-invasive patient interface assembly may include a full-face mask (sealed around the patient's nose, mouth, and eyes), a full-face mask (sealed around the patient's nose and mouth), or an oronasal mask (separately sealed with or around each of the patient's nose / nostrils and mouth). A non-invasive patient interface assembly that seals with the patient's nasal passages may be suitable for some patients. This non-invasive patient interface assembly may be in the form of a nasal mask (sealed around the patient's nose) or a nasal pillow mask (sealed with each of the patient's nostrils). If configured to operate in both invasive and non-invasive treatment modes, the gas source may be the same as the gas source used for invasive ventilation therapy. For the purposes of the present disclosure, NIV therapy is intended to include a bi-level ventilation mode and a continuous positive airway pressure (CPAP) mode.

[0007] In the case of nasal high flow (NHF) therapy, humidified gas is delivered to the patient at a relatively high flow rate through a non-sealed patient interface assembly such as a nasal cannula assembly, which delivers gas directly to the patient's nostrils through a pair of non-sealed forks. The patient may breathe spontaneously or may stop breathing, such as during anesthesia. A gas source with a humidifier can be used to deliver high-flow gas. If configured to further operate in NHF mode, the gas source and humidifier can be the same as the gas source and humidifier used for invasive or non-invasive treatment, or the gas source and humidifier can be integrated in a single flow therapy device. The flow therapy device can have an integrated flow generator, such as a blower that generates a gas flow from ambient air. The gas source and / or humidifier can control the characteristics of the gas flow, such as one or more of the flow rate, temperature, pressure, humidity, supplemental gas concentration, etc. The gas flow can be delivered to the nasal cannula assembly through an inspiratory catheter in a single-limb circuit. The exhaled gas can be exhaled through the patient's nostrils around the fork of the nasal cannula assembly or through the patient's mouth.

[0008] Changing a patient between different forms of respiratory therapy requires changing at least the patient interface assembly (e.g., the aforementioned invasive patient interface assembly, non-invasive patient interface assembly, and non-sealing patient interface assembly), and may further require changing one or more of the inspiratory conduit, expiratory conduit, and gas source.

[0224] Nasal high flow (NHF) therapy is a form of high flow therapy (HFT) delivered to the patient via a non-sealing nasal cannula assembly.

[0225] The high flow therapy discussed herein is intended to be given its typical ordinary meaning as understood by those skilled in the art, which generally refers to the following respiratory assistance system, which delivers a target flow of humidified respiratory gas via an intentionally unsealed patient interface assembly at a flow rate that is generally intended to meet or exceed the patient's inspiratory flow rate. Typical patient interface assemblies include, but are not limited to, nasal or tracheal patient interface assemblies. The typical flow rate for adults is generally in the range of, but not limited to, about fifteen liters / minute to about sixty liters / minute or greater than sixty liters / minute. The typical flow rate for pediatric patients (such as newborns, infants and children) is generally in the range of, but not limited to, about one liter / minute / kilogram of patient weight to about three liters / minute / kilogram of patient weight or greater. High flow therapy can also optionally include gas mixture compositions that include supplemental oxygen and / or the administration of therapeutic drugs. High flow therapy is commonly referred to as nasal high flow (NHF), humidified high flow nasal cannula (HHFNC), high flow nasal oxygen (HFNO), high flow therapy (HFT) or tracheal high flow (THF) and other common names.

[0226] For example, in some configurations, for an adult patient, "high flow therapy" can refer to delivering gas to the patient at a flow rate greater than or equal to about 10 liters per minute (10 liters per minute (LPM)), such as between about 10 LPM and about 100 LPM, or between about 15 LPM and about 95 LPM, or between about 20 LPM and about 90 LPM, or between about 25 LPM and about 85 LPM, or between about 30 LPM and about 80 LPM, or between about 35 LPM and about 75 LPM, or between about 40 LPM and about 70 LPM, or between about 45 LPM and about 65 LPM, or between about 50 LPM and about 60 LPM. In some configurations, for a neonatal, infant, or pediatric patient, "high flow therapy" may refer to delivering gas to the patient at a flow rate greater than 1 LPM, such as between about 1 LPM and about 25 LPM, or between about 2 LPM and about 25 LPM, or between about 2 LPM and about 5 LPM, or between about 5 LPM and about 25 LPM, or between about 5 LPM and about 10 LPM, or between about 10 LPM and about 25 LPM, or between about 10 LPM and about 20 LPM, or between about 10 LPM and 15 LPM, or between about 20 LPM and 25 LPM. A high flow therapy device for a neonatal, infant, pediatric, or adult patient may deliver gas to the patient at a flow rate between about 1 LPM and about 100 LPM, or at a flow rate in any of the subranges listed above.

[0227] High flow therapy can be effective in meeting or exceeding the patient's inspiratory needs, enhancing the patient's oxygenation and / or reducing the work of breathing. Additionally, high flow therapy can produce a flushing effect in the nasopharynx, so that the anatomical dead space of the upper airway is flushed by the high gas flow flowing in. The flushing effect can create a reserve of fresh gas available for each breath while minimizing rebreathing of carbon dioxide, nitrogen, etc.

[0228] The patient interface assembly for high flow therapy may be a non-sealing patient interface assembly to prevent barotrauma (which may include tissue damage to the lungs or other organs of the patient's respiratory system due to a pressure differential relative to the atmosphere). The patient interface assembly may be a nasal cannula assembly with a manifold and nasal prongs, and / or a face mask, and / or a nasal pillow mask, and / or a nasal mask, and / or a tracheostomy interface assembly, or any other suitable type of patient interface assembly.

[0229] Unless the context clearly requires otherwise, throughout the specification and claims, the words "comprises," "comprising," and variations are to be interpreted in an inclusive rather than exclusive sense. That is, these terms are to be interpreted in the sense of "including, but not limited to," rather than "consisting only of." Similarly, any examples listed in the following description are not intended to be limiting.

[0230] The phrases "when viewed along the longitudinal axis," "when viewed from above," and the like refer to relative component arrangements that are apparent only from that particular angle. For example, when viewed along the longitudinal axis, where two components are referred to as being diametrically opposed, the description is not intended to require (nor exclude) those identical components being spaced apart along the longitudinal axis (i.e., when viewed perpendicular to the longitudinal axis). Similarly, when two components are referred to as defining an angle between them when viewed along the longitudinal axis (from above / below), the description is not intended to require (nor exclude) those identical components being not spaced apart from each other along the longitudinal axis.

[0231] Any reference to a publication or product throughout this specification (including the background art) should not be taken as an admission that the publication or product is prior art, is similar, is widely known, or forms part of the common general knowledge in the field.

[0232] First example

[0233] First reference Figures 1 to 12 , shows a respiratory therapy accessory 100 according to a first example. The respiratory therapy accessory 100 includes a body 102 configured to be attached to a support 602 and three retaining members 104, 106, 108, each of which is configured to retain a respiratory therapy component.

[0234] Ontology

[0235] The body 102 of the respiratory therapy accessory 100 is a generally cylindrical, open-ended, hollow structure defining an elongated interior space 110. The body 102 opens into the interior space 110 at each of its opposite longitudinal ends. The body 102 includes a first arm 112 and a second arm 114 that are axially spaced apart from each other. The axial spacing of the elongated body 102 and / or the arms 112, 114 can improve the stability of the respiratory therapy accessory 100 when attached to a support.

[0236] The first arm 112 and the second arm 114 are each partially annular and extend arcuately in opposite circumferential directions about the longitudinal axis 202 of the body 102, depending from a spine 116, which in this example is formed by a front portion of the body 102. The spine 116 of the body 102 of this first example extends continuously between opposite longitudinal ends of the body 102 in a direction parallel to the longitudinal axis 202.

[0237] The body 102 of the respiratory therapy accessory 100 is at least partially formed of an elastically deformable material, such as an elastic plastic material, such that the first arm 112 and the second arm 114 are configured to elastically deform when the body 102 is attached to a support in use, as described in further detail below. In some examples, the respiratory therapy accessory 100 can be formed of a polymer, such as a rigid thermoplastic polymer having sufficient creep resistance, strength, and other such material properties. For example, suitable materials include acetal, nylon, or polyketone.

[0238] The retaining members 104, 106, 108 can be integrally molded with the body 102. The respiratory therapy accessory 100 can remain attached to the support for a long time and can be used with more than one patient. The respiratory therapy accessory 100 can be periodically disinfected by wiping with a disinfectant. In some examples, the materials can be selected so that the respiratory therapy accessory 100 is autoclavable.

[0239] like Figure 1 and Figure 2 As best shown, the first arm 112 defines a first portion of the interior space 110. The first arm 112 extends arcuately from a first side of the spine 116 and defines a first opening 118 to the interior space 110 between a distal end of the first arm 112 and an opposing second side of the spine 116.

[0240] like Figure 2 and Figure 4 As best shown, the second arm 114 defines a second portion of the interior space 110. The second arm 114 extends arcuately from a second side of the spine 116, defining a second opening 204 between a distal end of the second arm 114 and the first side of the spine 116.

[0241] The first opening 118 and the second opening 204 are disposed on opposite sides and ends of the body 102 .

[0242] The width of the first opening 118 of the respiratory therapy accessory 100 is narrower than the diameter of the first portion of the interior space 110 (ie, the inner diameter of the body 102 ). Similarly, the width of the second opening 204 is narrower than the diameter of the second portion of the interior space 110 .

[0243] The distal ends of the first and second arms 112, 114, and the opposite portions of the spine 116 include substantially flat opposing edges 120 at the respective first and second openings 118, 204. In the respiratory therapy accessory 100, the opposing edges 120 extend substantially parallel to the longitudinal axis 202. The opposing edges 120 can be substantially parallel to each other. In other examples, the opposing edges can diverge outwardly, and / or a pair of outwardly divergent extensions can be provided at the distal ends of the arms, similar to the embodiment of the present invention. Figure 3 Best shown are first retention member 104 and second retention member 106. These variations can each help guide the support into and through a respective opening when the respiratory therapy accessory 100 is attached to the support, as discussed in further detail below.

[0244] The opposing edge 120 is configured to determine, in part, the torque required to engage the first arm 112 and the second arm 114 of the body 102 with the support (as described in further detail below) such that the support is received within the interior space 110. For example, other factors that may affect the torque required to rotate the body 102 onto the support include, but are not limited to, the material of the body 102 and / or the support, the shape of the interior space 110, and the shape of the first arm 112 and / or the second arm 114.

[0245] Special reference Figure 2 and Figure 5 , the slot 206 extends between and connects the first opening 118 and the second opening 204. The slot 206 is configured to initially partially receive the support member into the interior space 110 when the respiratory therapy accessory 100 is attached, as described in further detail below. When viewed from the rear, the slot 206 of the respiratory therapy accessory 100 is angled relative to the longitudinal axis 202 of the body 102, as shown in FIG. Figure 5 Angled slot 206 can advantageously indicate to the user the direction of rotation to engage and / or disengage respiratory therapy accessory 100 with the support. In other examples, slot 206 can be perpendicular to longitudinal axis 202 of body 102.

[0246] It can be seen that the combination of the first opening 118, the second opening 204, and the slot 206 define a continuous angled split in the hollow cylindrical body 102. The continuous angled split extends from one side of the body 102 at a first end to an opposite second side at an opposite second end of the body 102. At the opposite end of the body, the split extends substantially parallel to the longitudinal axis 202. A central portion of the split at least partially extends circumferentially from one side of the body to the other side.

[0247] The slot 206 of the respiratory therapy accessory 100 can be slightly wider than the diameter of the support to which the respiratory therapy accessory 100 is intended to be attached. However, in other examples, the slot 206 can be at least partially equal to or narrower in width than the diameter of the support. In such examples, at least one of the body 102 and / or the support can be configured to deform as the support is received by the slot 206.

[0248] like Figure 5 As best shown, the lower edge of the first arm 112 and the upper edge of the second arm 114 may be beveled or chamfered to help guide the slot 206 around the support to correct any minor misalignment.

[0249] Attaching the body to the support

[0250] The respiratory therapy accessory 100 has no moving parts such as hinges, screws, or jaws. The respiratory therapy accessory is configured to be clamped onto the support by merely translating the respiratory therapy accessory 100 toward the support and then rotating the respiratory therapy accessory 100 as a whole to engage the support. This can advantageously make the respiratory therapy accessory 100 inexpensive to manufacture and / or simple and intuitive to use. The respiratory therapy accessory 100 can advantageously be able to be selectively engaged and / or disengaged anywhere along the length of the support. In some examples, the respiratory therapy accessory 100 can alternatively be slid directly down in an axial direction onto the top end of the support and fit over the top end. The open end of the body 102 can be beveled or chamfered to facilitate this.

[0251] Special reference FIG. 6A to FIG. 6D , the attachment of the respiratory therapy accessory 100 to the support is described in further detail.

[0252] exist Fig. 6A 602. The respiratory therapy accessory 100 of this first example is configured to be attached to the support 602 in the form of a tubular steel rod having a circular cross-section, such as, by way of non-limiting example, a rod forming part of an intravenous (IV) bag support, a water bag rod, a rolling stand, a ventilator cart, or a bed frame. The first arm 112 and the second arm 114 define an interior space 110 having a shape that generally corresponds to the outer surface of the support 602. As shown in FIG. Figure 2As shown, the first arm 112 and the second arm 114 define an annular shape suitable for engaging the cylindrical shaft of the rod, and may also be suitable for engaging certain other supports having a substantially circular cross-section (such as a hexagonal cross-section). However, in other examples, a respiratory therapy accessory according to the present disclosure may be configured to attach to other supports by having a correspondingly shaped interior space 110, including, by way of non-limiting example, supports having rectangular, square, oval, or polygonal cross-sections.

[0253] To attach the body 102 to the support 602, the body 102 may be rotated so that the slot 206 is substantially parallel to the support 602, such as Figure 6B Best shown, and along Fig. 6A The support member 602 moves in the direction indicated by the arrow translation direction 604 in FIG. 206 , so that the support member 602 is received by the slot 206 .

[0254] exist Figure 6B , the support member 602 is shown as being partially received within the interior space 110, having passed through the slot 206. At this stage, the slot 206 remains aligned with the support member 602.

[0255] As described above, the slot 206 is slightly wider than the diameter of the support 602. However, in alternative examples, the width of the slot 206 may be slightly narrower than the diameter of the support 602, and the body 102 and / or the support 602 may be configured to deform as the support 602 passes through the slot 206 and partially enters the interior space 110. This may improve or prevent the body 102 from being unintentionally disengaged from the support 602.

[0256] In order to engage the first arm 112 and the second arm 114 with the support 602 to securely attach the body 102 to the support 602, the body 102 may be moved along the Figure 6B 100 (or clockwise when viewed from the front of respiratory therapy accessory 100).

[0257] Reference again Figure 2 , the rotation is about the rotation axis 208. The rotation axis 208 for the respiratory therapy accessory 100 is perpendicular to the longitudinal axis 202 and passes through the slot 206 and the spine 116 of the body 102. For attaching the body 102 to the support 602, the rotation is in the direction indicated by the arrow 210. To disengage the first arm 112 and the second arm 114, the body can be rotated about the rotation axis 208 in the opposite direction.

[0258] refer to Figure 6C , rotation can be achieved by grasping and rotating the third retaining member 108 as indicated by arrow 606.

[0259] As the body 102 is initially rotated, the support 602 is received by the first opening 118 defined by the first arm 112 at one end of the body 102 and the second opening 204 defined by the second arm 114 at the opposite end of the body 102. As the body 102 is further rotated, the first arm 112 and the second arm 114 are elastically deformed outward to accommodate the support 602 within the respective openings 118, 204 between the opposite edges 120, and then elastically recover as the opposite edges 120 pass through the widest portion of the support 602 and the support 602 is further received within the interior space 110. In some examples, the sudden elastic recovery of at least one of the first arm 112 and the second arm 114 can prompt the respiratory therapy accessory 100 to finally engage with the support and provide tactile and / or audible feedback, thereby confirming that the body 102 is securely attached to the support 602 by "snapping". That is, the body 102 can be fixed to the support by snap-fitting by rotating the respiratory therapy accessory 100 as a whole.

[0260] Fig.6D The body 102 is shown attached to the support 602 , wherein the support 602 is fully received within the interior space 110 .

[0261] The body 102 of the respiratory therapy accessory 100 can be formed so that the diameter of the interior space 110 is slightly smaller than the width of the support 602 before attachment. That is, at least one of the first arm 112 and the second arm 114 can be configured so that it does not fully elastically recover when the support 602 is further received (e.g., fully received) within the interior space 110. The elasticity of the first arm 112 and the second arm 114 can therefore apply a compressive force to the support 602. This can increase the friction between the body 102 and the support 602 to improve or avoid the respiratory therapy accessory 100 from accidentally sliding down along the support 602. Alternatively or additionally, at least a portion of the body 102 can be formed or lined with a non-slip material that has a relatively higher coefficient of friction with the rod than one or more of nylon, acetal, or polyketone and the rod. By way of non-limiting example, at least a portion of the inner surface of the nylon body 102 can be overmolded with an elastomeric material such as liquid silicone rubber (LSR).

[0262] The body 102 of the respiratory therapy accessory 100 can be configured to selectively slide along the support 602 and / or rotate about the longitudinal axis of the support 602 to position the respiratory therapy accessory 100 at a desired location (e.g., height) and orientation on the support 602 when sufficient external force is applied to the body 102, such as by a user's hand. The respiratory therapy accessory 100 is configured such that the force required to slide the respiratory therapy accessory 100 along the support 602 exceeds the force acting on the combination of the respiratory therapy accessory 100 and any respiratory therapy components that may be desired to be simultaneously retained by the respiratory therapy accessory 100 due to gravity, but is not so great that the respiratory therapy accessory 100 cannot be selectively moved by the user with relative ease. In some examples, the respiratory therapy accessory 100 can be provided with a momentary actuator to selectively deform at least one of the first arm 112 and the second arm 114 outward to temporarily reduce friction with the support member, thereby reducing the force required to slide and / or rotate the body 102. The momentary actuator is, for example, a pair of levers attached to the first arm 112 and the second arm 114 that can be compressed together.

[0263] In some examples, respiratory therapy accessory 100 can include a locking mechanism (not shown) configured to lock body 102 to support 602 to improve or prevent body 102 from accidentally sliding down support 602. For example, the locking mechanism can include a grub screw or cam that abuts against an outer surface of support 602 to secure body 102 in place relative to support 602. To move body 102 along support 602, a user can loosen the grub screw or cam, slide body 102 along support 602, and then re-tighten the grub screw or cam once body 102 is in a desired position.

[0264] Retention components

[0265] The retention members may each be configured to retain a respiratory therapy component.By way of non-limiting example, the respiratory therapy component may be a respiratory conduit, a patient interface assembly, or packaging for a patient interface assembly.

[0266] The respiratory therapy accessory 100 of the first example includes three retaining members 104, 106, 108, each of which is configured to retain a different respiratory therapy component. More specifically, the first retaining member 104 is configured to retain the first patient interface assembly, the second retaining member 106 is configured to retain the first and / or second respiratory conduits, and the third retaining member 108 is configured to retain the second patient interface assembly. The first patient interface assembly and the second patient interface assembly can each be a different type of patient interface. Each of the first retaining member 104, the second retaining member 106, and the third retaining member 108 can therefore have a different shape, whereby they are structurally different from each other.

[0267] In other examples, the respiratory therapy accessory can be provided with: one or two of the first retaining member 104, the second retaining member 106, or the third retaining member 108; one or more alternative retaining members; two or more identical or similar retaining members (including but not limited to any one of two or more retaining members 104, 106, or 108); a combination of similar and different retaining members; four or more retaining members; or any combination of the foregoing.

[0268] Return to reference Figure 5 , the first retention member 104 of the exemplary respiratory therapy accessory 100 is spaced apart from the second retention member 106 along the longitudinal axis 202 of the body 102. For example, Figure 1 and Figure 5 As shown, the first retaining member 104 extends from the body 102 toward the upper end of the body 102 at or near the first arm 112, and the second retaining member 106 extends from the body 102 toward the lower end of the body 102 at or near the second arm 114. Figure 5 As best shown, the slot 206 is positioned between the first retention member 104 and the second retention member 106 .

[0269] In other examples, the first retention member 104 and the second retention member 106 can be spaced apart from one end of the body 102 by a similar or the same distance. For example, the first retention member 104 and the second retention member 106 can extend from the same point of the body 102, such as bifurcated. In such an example, the slot 206 can be positioned above (or below) both the first retention member 104 and the second retention member 106.

[0270] Reference again Figure 2 , at least when viewed along the longitudinal axis 202 (e.g., as Figure 3 ), the third retaining member 108 extends from the body 102 in a direction parallel to or aligned with the rotation axis 208. That is, the third retaining member 108 extends from the spine 116 and is circumferentially equidistant from the first opening 118 and the second opening.

[0271] The second retaining member 106 extends from the body 102 in a direction that can generate a torque on the body 102 in the direction of arrow 210. That is, the second retaining member 106 extends from a side of the body that is generally the same side as the side that includes the first upper opening 118 and is generally opposite to the side that includes the second lower opening 204. As shown in the figure, when viewed along the longitudinal axis 202, as shown in FIG. Figure 3As best shown, the second retention member 106 can extend in a direction that is not perpendicular to the axis 208. That is, the second retention member 106 extends in a direction that is not directly opposite the second opening 204 (although in alternative examples, this can be done, as described below with respect to the second example).

[0272] In use, downward forces on each of the third retention member 108 and the second retention member 106 will therefore not tend to generate a torque that would tend to disengage the first arm 112 from the support 602.

[0273] The first retaining member 104 extends from the body 102 in a direction that can generate a torque about the rotation axis 208 in a direction opposite to the arrow 210. The first arm 112 and / or the second arm 114 are configured to grip onto the support 602 sufficiently to overcome the torque. Figure 3 As best shown, torque may also be improved to some extent by extending the first retention member 104 in a direction that is not perpendicular to the axis 208. That is, the first retention member 104 extends in a direction that is not directly opposite the first opening 118. Torque may also be balanced by the opposing torque generated by the second retention member 106. In other examples, the first retention member 104 may be omitted, or may extend in a direction that is directly or substantially opposite to the direction of the third retention member 108.

[0274] Special reference Figure 3 , it can be seen that when viewed along longitudinal axis 202, first retention member 104 and second retention member 106 of respiratory therapy accessory 100 each form an acute angle with third retention member 108. These acute angles in this example are equal. That is, third retention member 108 bisects the angle between first retention member 104 and second retention member 106.

[0275] The first retaining member 104 of the exemplary respiratory therapy accessory 100 can be configured to retain a patient interface assembly for delivering respiratory gases to a patient for nasal high flow (NHF) therapy. The patient interface assembly can be a non-sealed nasal cannula assembly, which includes: a nasal cannula; a conduit that is fluidly coupled to the nasal cannula at one end; and a connector that is attached to the opposite end of the conduit and is configured to connect the conduit to an inspiratory conduit when the nasal cannula assembly is used to deliver respiratory therapy to the patient. The nasal cannula can include a pair of prongs for insertion into the patient's nostrils, which are fluidly coupled to a manifold configured to receive respiratory gases from the conduit. When the nasal cannula assembly is used to deliver respiratory therapy to the patient, a headgear can also be attached to the nasal cannula to secure the nasal cannula assembly to the patient's head.

[0276] Special reference Figure 7and Figure 8 , the depicted first retaining member 104 of the respiratory therapy accessory 100 is configured to retain an Optiflow™+ nasal cannula assembly or an Optiflow™ 3S nasal cannula assembly, both available from Fisher & Paykel Healthcare of Auckland, New Zealand. Figure 8 The Optiflow™+ nasal cannula assembly 802 is shown by way of example.

[0277] The first retaining member 104 includes a partial annular portion 702 defining an interior space 704. The first retaining member 104 also includes a partial annular portion 702 and a body 102 ( Figure 7 In some examples, the first retaining member 104 may omit the handle 706 so that the partial annular portion 702 extends directly from the body 102.

[0278] The interior space 704 includes an upper connector portion 708 configured to receive the connector 804 of the nasal cannula assembly 802 and a lower conduit portion 710 configured to receive the conduit 806 of the nasal cannula assembly 802. The connector portion 708 and the conduit portion 710 are coaxially arranged. The width of the connector portion 708 is greater than the corresponding width of the conduit portion 710. For example, the diameter of the connector portion 708 is greater than the diameter of the conduit portion 710.

[0279] The distal end of the partial annular portion 702 defines an opening 712 leading to the interior space 704. The opening 712 is configured to allow the elastic tube 806 of the nasal cannula assembly to pass through, but prevent the relatively rigid connector 804 from passing through. The distal ends of the partial annular portion 702 diverge away from the interior space 704, and these distal ends are thus configured to guide the tube 806 toward the opening 712 and pass through the opening into the interior space 704. The tube 806 can be elastically deformable. The tube can be corrugated. In some examples, the width of the opening 712 can be less than or equal to the maximum outer diameter of the tube 806. The tube 806 can be deformed when it passes through the opening 712 by applying a suitable insertion force. This can reduce the possibility of the tube 806 accidentally passing through the opening 712 backward, which may cause the nasal cannula assembly 802 to move out of the first retaining member 104 and fall to the ground. However, in some examples, the width of the opening 712 can be greater than the outer diameter of the tube 806, so that the tube 806 does not need to be deformed when it passes through the opening 166.

[0280] The width of the connector portion 708 of the partial annular portion 702 is slightly wider than the corresponding width of the connector 804. For example, the connector portion 708 defines a diameter that is slightly wider than the outer diameter of the connector 804 at its proximal end, such as Figure 8 shown.

[0281] The conduit portion 710 of the partial annular portion 702 is partially defined by a boss 714. The boss 714 extends from the partial annular portion 702 toward the interior space 704. Figure 8 As best shown, the boss 714 provides the partial annular portion 702 with a generally “L” shaped cross-section.

[0282] The boss 714 is configured to abut against a lower surface of the connector 804 such that the connector 804 rests on the boss 714 substantially coaxially with the partial annular portion 702 and the interior space 704. The conduit 806 of the nasal cannula assembly 802 depends from the connector 804. The nasal cannula and an attached headgear (neither shown) are suspended from opposite ends of the conduit 806.

[0283] In the respiratory therapy accessory 100, the boss 714 forms the bottom surface of the partial annular portion 702. In other words, the boss 714 protrudes inward from the lower region of the partial annular portion 702. This allows the upper connector portion 708 to accommodate the lower end of the connector 804, as described in further detail below. However, in alternative examples, the boss 714 can protrude inward from the upper region or middle region of the partial annular portion 702. For example, the boss 714 can alternatively protrude inward from the midpoint of the partial annular portion 702 into the interior space 704 (i.e., defining a "T" shaped cross-section). This can be advantageous if the respiratory therapy accessory is configured to be equally usable when attached to the support in either orientation.

[0284] The arcuate wall 716 extends between the upper surface of the partial annular portion 156 and the upper surface of the boss 714. The arcuate wall 716 is configured to partially surround the connector 804 and reduce lateral movement of the connector within the connector portion 708 of the interior space 704, such as Figure 8 The combination of the arcuate wall 716 and the upper surface of the boss 714 defines a connector portion 708 that is configured to bridge the lower end of the connector 804 .

[0285] The partial annular portion 702 is configured to partially surround the connector 804 at an angle exceeding 180°. That is, the partial annular portion 702 is configured to extend around more than half of the circumference of the connector 804 and the tube 806 of the nasal cannula assembly. This can improve or prevent the connector 804 from being accidentally removed from the first retaining member 104. Therefore, in order to place the connector 804 on the boss 714, the user needs to position the connector 804 above the top surface of the partial annular portion 702 and then lower the connector 804 into the interior space 704 until the connector 804 abuts against and rests on the boss 714 in the connector portion 708. Similarly, unless the connector 804 is first raised above the arcuate wall 716 of the partial annular portion 702, the arcuate wall 716 can inhibit the removal of the connector 804 in the lateral direction. This can be advantageously used to further inhibit the nasal cannula assembly 802 from being inadvertently removed from the first retention member 104, because the connector 804 can be made of a rigid plastic material that is not easily deformed to allow the connector 804 to pass through the opening 712. However, in some examples, the partial annular portion 702 can be configured to be elastically deformed, optionally by applying sufficient force, sufficient to allow the connector 804 to be removed in a lateral direction. This can advantageously improve or prevent damage to the partial annular portion 702 and / or the connector 804.

[0286] Figure 8 Shown in Figure 7 806, and additionally partially illustrates the nasal cannula assembly 802. The connector 804 of the nasal cannula assembly 802 defines a shoulder 808. The shoulder 808 is a lower portion of the illustrated connector 804 having a larger diameter than the adjacent conduit 806. The shoulder 808 is configured to abut against the boss 714. The shoulder 808 can be configured to be positioned at or near a corner defined between the boss 714 and the arcuate wall 716. The arcuate wall 716 can be configured to partially surround the shoulder 808. Figure 8 As can be seen in the figure, the shoulder 808 is supported by the combination of the protrusion 714 and the arcuate wall 716.

[0287] The conduit 806 is suspended from the connector 804. The diameter of the conduit 806 may be smaller than the diameter of the conduit portion 710 of the first retaining member 104, so that the conduit 806 is freely suspended within the conduit portion 710, hanging from the connector 804. Figure 8As shown, in use, the connector 804 can be retained in a substantially upright position by the boss 714 so that the conduit is suspended substantially vertically, coaxially with the connector 804 and the partial annular portion 702. However, in some examples, the support 602 may not necessarily be strictly vertical, or the first retaining member 104 may be angled so that it is not strictly horizontal. In such examples, the connector 804 may not necessarily remain strictly upright, and at least a portion of the conduit may not be strictly vertical or coaxial with the hanging connector 804 during use. In addition, the weight of the nasal cannula and the headgear (not shown) on the conduit 806 may cause the conduit to be suspended at an angle relative to the vertical line. Suspension of the nasal cannula assembly by the connector 804 can be beneficial in facilitating the discharge of any condensate present in the conduit 806 after being used to deliver humidified respiratory gases to the patient.

[0288] refer to Fig. 9 The second retaining member 106 is configured to retain the first and / or second breathing conduits used to deliver the flow of breathing gas to a non-sealed nasal cannula assembly for nasal high flow (NHF) therapy, or to a sealed patient interface assembly for non-invasive ventilation (NIV) therapy.

[0289] Various breathing catheters may be corrugated, helically wound so as to have one or more helical undulations on their outer surface, or may have a smooth, non-undulating outer surface. For example, a breathing catheter may have a first elongated member helically wound with a second elongated member to define an inner cavity and an undulating outer surface. Corrugated and helically wound breathing catheters each have a series of alternating peaks and valleys in an axial direction and may therefore be said to have a maximum outer diameter and a minimum outer diameter. Referring briefly to Fig.10 , the maximum outer diameter 1002 refers to the outer diameter of the conduit when measured peak to peak on opposite sides of the conduit. The minimum outer diameter 1004 refers to the outer diameter of the conduit when measured valley to valley on opposite sides of the conduit. The difference between the maximum outer diameter and the minimum outer diameter of a corrugated conduit is generally greater than that of a spirally wound conduit or other conduits having an undulating outer surface. For purposes of the present disclosure, a conduit having a smooth, non-undulating outer surface may also be considered to have a maximum outer diameter and a minimum outer diameter, although it should be understood that they may be substantially equal.

[0290] The second retaining member 106 can be configured to retain each of the first breathing tube and the second breathing tube. The first breathing tube can have a relatively large maximum outer diameter and / or a minimum outer diameter, and the second breathing tube can have a relatively small maximum outer diameter and / or a minimum outer diameter. The first breathing tube and the second breathing tube can be configured for different forms of respiratory therapy, such as NIV and NHF, respectively. In another example, the second retaining member 106 can be configured to retain each of the first breathing tube suitable for use with adults and the second breathing tube having a smaller maximum outer diameter suitable for use with infants and / or pediatric patients. However, in some examples, the first breathing tube and the second breathing tube can have the same maximum outer diameter and minimum outer diameter.

[0291] For example, the breathing conduit may include one or more heating elements 1006, which are configured to heat the gas flowing through the breathing conduit from a gas source such as a ventilator, a gas bottle or a wall source. Some breathing conduits may also include a patient end temperature sensor or other sensor. The breathing conduit may be configured to be connected to the outlet of a humidifier at one end and to be connected to a patient interface assembly at the opposite end. The humidifier may be positioned between the ventilator and the patient, or may be integrated with a blower. The breathing conduit may be part of a double limb circuit. That is, a breathing conduit in the form of an inspiratory conduit may be connected to an expiratory conduit by a Y-shaped piece, which delivers the gas exhaled from the patient back to the ventilator. The second retaining member 106 may be configured to directly retain the inspiratory conduit, thereby indirectly retaining the expiratory conduit and the Y-shaped piece. Alternatively, the second retaining member 106 may directly retain the expiratory conduit. In some examples, the second retaining member 106 may be configured to directly retain both the inspiratory conduit and the expiratory conduit at the same time.

[0292] Fig. 9 An exemplary second retention member 106 is shown in detail, with the body 102 and other retention members of the respiratory therapy accessory 100 omitted for clarity. The second retention member 106 includes a handle 902 and a pair of retention arms 904. The pair of retention arms 904 are spaced apart from the body 102 by the handle 902. The handle 902 can space one or more respiratory therapy components retained by the second retention member 106 from the body 102 and the support 602. The handle 902 increases the distance between the second retention member 106 and the body 102, which in turn increases the torque acting on the support 602 when in use, which can further stabilize the body 102 on the support 602. However, in some examples, the handle 902 can be omitted.

[0293] The pair of retaining arms 904 is connected at or near the handle 902 at the proximal end. The distal ends of the pair of retaining arms 904 define an opening 306 leading to the interior space. The pair of retaining arms 904 converge toward each other at a waist region 906 intermediate the respective distal and proximal ends, so that the pair of retaining arms 904 define a first retaining space 302 and a second retaining space 304. The first retaining space 302 and the second retaining space 304 together define a single continuous interior space. That is, the waist region 906 conceptually divides the single continuous interior space defined by the retaining arms 904 into first retaining spaces 302 and second retaining spaces 304, each of which is approximately circular. Therefore, the pair of retaining arms 904 and the combination of the first retaining spaces 302 and the second retaining spaces 304 each have a generally 8-shaped shape. The waist region 906 is located between the first retaining spaces 302 and the second retaining spaces 304 and is narrowed relative to the adjacent first retaining spaces 302 and the second retaining spaces 304. The first retention space 302 is located closer to the body 102 than the second retention space 304. The opening 306 provides direct access to the second retention space 304, and indirect access to the first retention space 302 via the second retention space 304.

[0294] The distal ends of the retention arm pair 904 diverge outwardly away from the second retention space 304. The diverging distal ends are configured to guide the breathing tube toward the opening 306 and through the opening into the second retention space 304. The retention arm pair 904 and / or the breathing tube can be elastically deformed when the breathing tube passes through the opening 306.

[0295] The first retention space 302 and the second retention space 304 of the exemplary respiratory therapy accessory 100 are each configured to receive a different respiratory catheter. Figure 3 As best shown, it will be observed that the first retention space 302 and the second retention space 304 each have different widths or diameters, with the relatively larger second retention space 304 being located proximate the opening 306. The second retention space 304 is thus configured to retain a breathing catheter having a relatively larger maximum outer diameter and / or minimum outer diameter (e.g., 25 mm) than a breathing catheter received by the first retention space 302 (e.g., 22 mm). A narrower catheter is able to pass through each of the opening 306, the second retention space 304, and the waist region 906 to be received by the first retention space 302, while a relatively larger breathing catheter is able to pass through the opening 306 into the second retention space 304, but further movement of the relatively larger breathing catheter into the first retention space 302 is inhibited by the narrowed waist region 906.

[0296] The illustrated example of second retention member 106 is designed to retain only one of the two different catheters at a time (since the catheter will extend into waist region 906 and possibly into another of these retention spaces). However, in some examples, waist region 906 may be elongated to avoid interference between catheters retained within first retention space 302 and second retention space 304, so that both catheters may optionally be retained by second retention member 106 simultaneously if desired.

[0297] The second retention member 106 includes a boss 908 configured to support the one or more respiratory therapy components. The boss 908 extends from the retention arm pair 904 toward the interior spaces 302, 304. The boss 908 is configured to engage the outer surface of the inspiratory catheter 1008. Fig.10 As best shown, the boss 908 is configured to engage the corrugated portion 1010 of the inspiratory catheter 1008. The boss 908 may alternatively engage the undulations in the outer surface of an alternative respiratory catheter (including a spirally wound respiratory catheter, such as the AirSpiral™ catheter available from Fisher & Paykel Healthcare), and / or may be gripped onto an alternative respiratory catheter having a substantially smooth outer surface that is neither corrugated nor undulating. In the case of a respiratory catheter having an undulating outer surface, the minimum outer diameter may be slightly less than the maximum outer diameter, depending on the depth of the undulations. In the case of a respiratory catheter having a smooth outer surface, the minimum outer diameter may be the same as the maximum outer diameter. The boss 908 may be sized to correspond substantially to the outer surface of the inspiratory catheter 1008. In other examples, the boss 908 may not necessarily correspond to the outer surface of the respiratory catheter, but may still be able to retain the respiratory catheter by an interference fit and / or friction engagement.

[0298] The boss 908 of the exemplary second retention member 106 extends substantially perpendicularly from the pair of retention arms 904 and tapers at least partially toward the interior spaces 302 , 304 .

[0299] Fig.10 Shown in Fig. 9 BB of FIG. 1 and 10, and also partially showing the suction tube 1008. The size of the boss 908 is determined to correspond roughly to the corrugated portion 1010 of the suction tube 1008. More specifically, the shape and size of the boss 908 are determined to correspond to the valley of the corrugated portion 1010 of the suction tube 1008. The boss 908 has a cross-section with a generally parabolic profile and protrudes from the retaining arm 904 by a distance that is approximately equal to the depth of the corrugated portion 1010 of the suction tube 1008.

[0300] The boss 908 within the first retention space 302 defines a width or diameter of the first retention space 302 that is smaller than the maximum outer diameter 1002 of the corresponding portion of the suction conduit 1008, such that the corrugated portion 1010 rests on top of the boss 908, supporting the suction conduit 1008 on the second retention member 106. The boss 908 can define a width or diameter of the first retention space 302 that is equal to or slightly larger than the minimum outer diameter 1004 of the suction conduit 1008, such that the conduit 1008 is not deformed when retained by the second retention member 106. However, in some examples, the width or diameter defined by the boss 908 can be smaller than the minimum outer diameter 1004.

[0301] The boss 908 is similarly configured to engage the second retention space 304 ( Fig.10 ) in a breathing tube (not shown) (although its minimum outer diameter 1004 and maximum outer diameter 1002 are larger).

[0302] Fig.10 A corrugated breathing tube is shown. The second retention member 106 can alternatively engage and retain a breathing tube having an undulating outer surface (having less pronounced peaks and valleys) and / or a breathing tube having a smooth, non-undulating outer surface. For example, a breathing tube having undulations can be formed by, for example, helically wrapping a hollow elongated member and a bead in a double helix pattern. AirSpiral ™ A breathing catheter is an example of such a breathing catheter. The size and shape of the boss 908 can be determined to engage the undulating portion similarly to the corrugated portion 1010. That is, the boss 908 extends into the valley so that the peak of the undulating portion rests on the upper surface of the boss 908. Alternatively or additionally, the size and shape of the boss 908 and the retention spaces 302, 304 can be determined to compress the undulating breathing catheter. The smooth breathing catheter can be similarly retained by compression. In some examples, any of the corrugated, undulating or smooth breathing catheters can alternatively be retained by interference with the connector, similar to the way the non-sealed nasal cannula assembly 802 is retained by the first retaining member 104.

[0303] The inspiratory conduit 1008 is suspended substantially perpendicular to the second retaining member 106, coaxial with the corresponding retaining space, and presents a substantially linear configuration. That is, the respiratory conduit 140 can be retained in a substantially vertical upright position, such as Fig.10As shown. This can facilitate the discharge of any condensate accumulated in the inspiratory conduit 1008 during the use of delivering humidified respiratory gases during respiratory therapy. The vertical or substantially vertical configuration of the inspiratory conduit 1008 can also be advantageous in minimizing the occupied space occupied by the inspiratory conduit 1008, thereby reducing the storage space requirements and / or the possibility of blocking or being accidentally knocked compared to the folded or coiled respiratory conduit. In some examples, the second retaining member 106 can be angled upward or downward, and at least a portion of the inspiratory conduit 1008 may not be retained in a strictly vertical upright position. That is, the inspiratory conduit 1008 can be bent at or near the point where it is retained by the protrusion 908. However, the fluid can still be discharged from the inspiratory conduit 1008. It will also be understood that the inspiratory conduit 1008 may not tend to be linear and / or vertically suspended, but may be curved, due to being coiled (e.g., having some "memory") for packaging and storage before use. Suspending the suction conduit 1008 on or near one end may help allow the suction conduit 1008 to relax and straighten somewhat, or at least not induce further bends in the suction conduit 1008 .

[0304] The third retaining member 108 of the exemplary respiratory therapy accessory 100 is configured to retain a patient interface assembly for delivering breathing gas to a patient for invasive ventilation, non-invasive ventilation (NIV), or nasal high flow (NHF) therapy. The third retaining member 108 can be longer than the first retaining member 104 and the second retaining member 106. That is, the third retaining member 108 can protrude further from the body 102 than either of the first retaining member 106 and the second retaining member 108, such as Figure 3 Best shown.

[0305] The third retaining member 108 of the respiratory therapy accessory 100 includes a hook portion 122, such as Figure 1 and Figure 4 102 is best shown. The third retaining member 108 extends downward from the body 102 and then bends upward at the distal end into the hook 122. That is, the third retaining member 108 terminates at the hook 122 at the distal end of the third retaining member 108. In some examples, the third retaining member 108 can omit the hook 122. For example, the third retaining member 108 can be a straight or curved beam extending from the body 102. For example, this can be advantageous if the respiratory therapy accessory is intended to be attached to the support in either orientation. In other examples, the third retaining member 108 can include multiple hooks 122.

[0306] A support member in the form of a post 126 extends from the body 102 to the third retention member 108, joining at approximately its midpoint to support the third retention member 108. In some examples, the first retention member 104 and / or the second retention member 106 may be similarly supported by a support member such as the post 126.

[0307] The third retention member 108 may retain a patient interface assembly (not shown) that is to be coupled during treatment to the inspiratory conduit 1008 retained by the second retention member 106. The patient interface assembly may be a full face mask (configured to seal around the patient's eyes, nose, and mouth), a full face mask (configured to seal around the patient's nose and mouth), an oronasal mask (configured to seal with each of the patient's nose / nostrils and mouth), a nasal mask (configured to seal around the patient's nose), a nasal pillow mask (configured to seal with the patient's nostrils), a nasal cannula assembly, an endotracheal tube, a tracheostomy tube, or any other patient interface assembly.

[0308] For example, a full face mask can be suspended on the hook 122 by positioning the headgear of the full face mask on the hook, wherein the full face mask is suspended below the hook. Alternatively, the hook 122 can be positioned in the inflatable chamber formed by the seal of the full face mask, for example, at the vertex or bridge of the nose region of the mask. In some examples, the hook 122 can be alternatively or additionally configured to retain a package containing a patient interface assembly (e.g., a package of an endotracheal tube configured for invasive ventilation therapy). By way of non-limiting example, the package can include a plastic bag or container (e.g., a clamshell package) having a keyhole aperture that is configured to be received by the hook 122.

[0309] Hook 122 can optionally be used to secure other respiratory therapy components. In one example, a Y-shaped piece with an expiratory tube attached can be hung on hook 122 by positioning the corner of the Y-shaped piece on the hook, wherein the expiratory tube is optionally suspended below the Y-shaped piece.

[0310] The hook portion 122 includes an enlarged portion 124 at its distal end. Figure 4 As shown, the enlarged portion 124 extends inwardly toward the body 102 relative to adjacent portions of the hook portion 122. The enlarged portion 124 of the hook portion 122 can prevent or at least reduce the likelihood that the patient interface assembly or packaging will inadvertently disengage from the hook portion 122.

[0311] refer to Fig.11 , respiratory therapy accessory 100 is shown attached to support 602 and securing two respiratory therapy components in place in use.

[0312] The first retaining member 104 is shown to retain a respiratory therapy component in the form of a patient interface assembly configured for nasal high flow therapy, specifically the Optiflow™+ nasal cannula assembly 802. A connector 804 and tubing 806 of the nasal cannula assembly 802 are shown. The nasal cannula and attached headgear can be suspended from opposite ends of the tubing 806. As described above, the shoulder 808 of the connector is bridged by the first retaining member 104. As described above, the first retaining member 104 is also configured to alternatively retain at least the Optiflow™+ nasal cannula assembly 802. ™ 3S Nasal Cannula Assembly Retention. In other examples, the first retention member 104 can be configured to retain any alternative patient interface assembly or respiratory therapy component.

[0313] The second retaining member 106 retains another respiratory therapy component in the form of a respiratory catheter that is configured to be coupled to a patient interface assembly suitable for non-invasive therapy. Specifically, the respiratory catheter shown is a corrugated inspiratory catheter 1102 that forms part of the RT232 Adult Optiflow™ Circuit Kit available from Fisher & Paykel Healthcare of Auckland, New Zealand. The inspiratory catheter 1102 is configured to fluidly couple with the connector 804 of the Optiflow™+ nasal cannula assembly 802. As described above, the inspiratory catheter 1102 is retained in the first retaining space 302 by the second retaining member 106, at least in part, by engaging the corrugated portion of the inspiratory catheter 1102 with the boss 908. However, the second retention member 106 can be configured to receive and retain a range of 22 mm respiratory catheters, including the AirSpiral™ inspiratory catheters in the 850A61 F&P 850 Adult NIV and NHF Circuit Kit and the 950A61 F&P 950 Adult Bi-Level / CPAP Heated Circuit Kit, both also available from Fisher & Paykel Healthcare. These inspiratory catheters are not corrugated, but have an undulating outer surface. Similarly, the second retention space 304 ( Fig.11 The ventilator (open center) can accommodate and retain a range of 25 mm breathing tubes. An example is the inspiratory tube of the RT319 F&P 850 Bi-Level / CPAP Circuit Kit, also available from Fisher & Paykel Healthcare.

[0314] The nasal cannula assembly 802 and the inspiratory catheter 1102 are each held by the respiratory therapy accessory 100 in a substantially linear and / or vertical configuration, which can provide one or more advantages of facilitating drainage of condensation within the tubing, loosening tubing that may have been coiled for packaging and storage, avoiding contact with contaminated or unsanitary surfaces, and minimizing the space occupied by the respiratory therapy accessory 100 and the respiratory therapy components retained therein.

[0315] The third retention member 108 may retain a patient interface assembly (not shown) and / or a packaging (not shown) containing the patient interface assembly, as described above.

[0316] refer to Fig.12 In some examples, by way of non-limiting example, the support member 602 itself can also be configured to retain a respiratory therapy component, such as a sterile water bag 1202 for delivering humidification fluid to a humidifier.

[0317] In some examples, a retention member of a respiratory therapy accessory according to the present disclosure may extend from the body in multiple directions that span an angle of 180° or less, 140° or less, 120° or less, or 90° or less. By way of non-limiting example, when viewed along longitudinal axis 202, as shown in FIG. Figure 3 As shown, the first retention member 104 and the second retention member 106 of the respiratory therapy accessory 100 define an angle of approximately 120°. That is, for example, an angle of approximately 140° is defined between a first axis passing through the handle 706 of the first retention member 104 and a second axis passing through the handle 902 of the second retention member 106. In this example, the first and second axes (and the third axis passing through the third retention member 108) intersect at the longitudinal axis of the body 102 because the retention members 104, 106, 108 extend radially from the body 102. Alternatively, in some examples where the respective handles of the first and second retention members 104, 106 are omitted, the angle may be defined between the first axis bisecting the first retention member 104 and the second axis bisecting the second retention member 106 when viewed along the longitudinal axis 202. Alternatively, in some examples where a handle is present, the angle may be defined between an axis bisecting one of the retention members and an axis passing through the handle of the other retention member. For example, where the handle 706 is omitted, the angle may be defined between an axis bisecting the first retention member 104 and an axis passing through the handle 902 of the second retention member 106 (which may also bisect the second retention member 106).

[0318] This provides space for a sterile water bag 1202 or other accessory to be suspended from the support 602 adjacent to the respiratory therapy accessory 100, thereby alleviating interference from the retaining members 104, 106, 108 or any respiratory therapy components retained by the respiratory therapy accessory, such as Fig.12 For example, the respiratory therapy accessory 100 and / or the sterile water bag 1202 may be arranged such that the water bag is disposed on a side of the body 102 that is generally opposite to the third retaining member 108 and the spine 116, as shown in FIG. Fig.12As shown. In addition, this provides sufficient space for respiratory therapy components to be suspended on retention members 104, 106, 108 while reducing the risk that they may come into contact with each other. In some examples, the respiratory therapy accessories can also be configured to selectively rotate or slide relative to support 602, and the disclosed angular arrangement of retention members 104, 106, 108 allows the respiratory therapy accessory 100 to rotate to accommodate a sterile water bag 1202 or other accessories adjacent to the respiratory therapy components, and / or slide along support 602 to pass the sterile water bag or other accessories to reduce interference or otherwise adjust the height of the respiratory therapy accessories.

[0319] Second example

[0320] Fig.13 A second example of a respiratory therapy accessory 1300 is shown. The respiratory therapy accessory 1300 is generally similar to the respiratory therapy accessory 100 of the first example. For the sake of brevity, some differences will be described in detail below. The description of the respiratory therapy accessory 100 of the first example may also apply to equivalent integers of this second example.

[0321] Similar to respiratory therapy accessory 100 , respiratory therapy accessory 1300 includes a body 1302 that is configured to be clipped to a support by translation and rotation. A first retention member 1304 , a second retention member 1306 , and a third retention member 1308 extend radially from body 1302 .

[0322] When viewed along the longitudinal axis, the first retaining member 1304 and the second retaining member 1306 in this second example extend from the body 102 in exactly opposite directions. Therefore, when viewed along the longitudinal axis, the first retaining member 1304, the second retaining member 1306, and the third retaining member 1308 extend in a direction spanning an angle of 180° relative to the longitudinal axis. The first retaining member 1304 and the second retaining member 1306 are spaced apart from each other in the direction of the longitudinal axis.

[0323] The first retention member 1304 and the second retention member 1306 of the respiratory therapy accessory 1300 omit the handle of the respiratory therapy accessory 100. That is, the partial annular portions of the first retention member 1304 and the second retention member 1306 extend directly from the body 1302. The respiratory therapy accessory 1300 and any respiratory therapy components retained by the respiratory therapy accessory 1300 can therefore occupy a relatively small footprint compared to the respiratory therapy accessory 100. The torque generated by the weight of the respiratory therapy components acting on the first retention member 1304 and the second retention member 1306 can be reduced.

[0324] The first and second retention members 1304, 1306 of this second example omit the outwardly diverging distal extensions of the first example.

[0325] The second retaining member 1306 of the respiratory therapy accessory 1300 is configured to directly retain a single respiratory catheter, or a series of respiratory catheters having the same or similar maximum outer diameter and / or minimum outer diameter. However, the respiratory catheters can form part of a two-limb circuit including an inspiratory catheter, an expiratory catheter, and a Y-piece fluidly connecting the inspiratory catheter and the expiratory catheter. The respiratory therapy accessory 1300 can retain the two-limb circuit by engaging one of the inspiratory catheter or the expiratory catheter with the second retaining member 1306.

[0326] Third Example

[0327] Fig.14 A respiratory therapy accessory 1400 according to a third example is shown. This third example is generally similar to the respiratory therapy accessory 100 and the respiratory therapy accessory 1300. For the sake of brevity, some differences will be described in detail below. The description of the respiratory therapy accessory 100 of the first example and the respiratory therapy accessory 1300 of the second example can also be applied to the equivalent entirety of this third example.

[0328] Respiratory therapy accessory 1400 includes a body 1402 configured to be attached to a support. A first retention member 1404, a second retention member 1406, and a third retention member 1408 extend from body 1402.

[0329] The body 1402 in this third example includes a first hollow structure 1410 and a second hollow structure 1412 that are attached or integrally formed side by side with parallel longitudinal axes.

[0330] like Fig.14 As is clear from the figure, the first hollow structure 1410 of the body 1402 is similar to the body 102 of the first example, and is similarly configured to be clamped to a support by translation and rotation. However, other attachment mechanisms may be used in alternative examples.

[0331] The second hollow structure 1412 of the body 1402 has a hexagonal outer cross-section and a cylindrical inner cross-section. Compared to a circular cross-section, the hexagonal outer cross-section can be easier for the user to hold, and / or visually distinguish the first hollow structure 1410 from the second hollow structure 1412. The second hollow structure has an orifice 1414 at the first (lower) end, but may be closed at the opposite (upper) end (not shown). The orifice 1414 is configured to receive a support into the interior of the second hollow structure 1412. The entrance of the orifice 1414 can be chamfered to guide the support into the second hollow structure 1412. In use, as an alternative to using the first hollow structure 1410, the respiratory therapy accessory 1400 can be optionally mounted to the top of the support. The respiratory therapy accessory 1400 can be slid down from the top of the support until the support engages the closed upper end of the second hollow structure 1412.

[0332] The interior of the aperture 1414 and the second hollow structure 1412 are adapted to engage a cylindrical support, and may also be adapted to engage certain other supports having a non-circular cross-section, such as a hexagonal cross-section. However, in other examples, the aperture 1414 and the second hollow structure 1412 may be configured to attach to other supports, including supports having a rectangular, square, elliptical, or polygonal cross-section, by having a corresponding interior shape.

[0333] In some examples, first hollow structure 1410 and second hollow structure 1412 can have different inner diameters or cross-sections to allow respiratory therapy accessory 1400 to be used with different supports.

[0334] The first retention member 1404, the second retention member 1406, and the third retention member 1408 of the respiratory therapy accessory 1400 each extend from the second hollow structure 1412 of the body 1402. When the respiratory therapy accessory 1400 is attached to a support using the first hollow structure 1410, this advantageously allows the retention members and any respiratory therapy components retained to be spaced further from the support and / or the sterile water bag 1202. The third retention member 1408 is directly opposite the first hollow structure 1410. The first retention member 1404 and the second retention member 1406 are directly opposite each other. The first retention member 1404 and the second retention member 1406 are both spaced an equal distance from one end of the body 1402.

[0335] Fourth Example

[0336] Figures 15 to 19A respiratory therapy accessory 1500 according to a fourth example is shown. The respiratory therapy accessory 1500 is generally similar to the respiratory therapy accessory 100 of the first example. Similar to the first example, the respiratory therapy accessory 1500 of this fourth example includes a body 1502 that is configured to be attached to a support. A first retaining member 1504, a second retaining member 1506, and a third retaining member 1508 extend from the body 1502. The body 1502 has a generally cylindrical hollow shape defining an interior space 1510, and includes a first arm 1512 and a second arm 1514 that arcuately extend from a spine 1516 to define a first opening 1518 and a second opening 1520 in the body 1502. An angled slot 1522 extends between and connects the first opening 1518 and the second opening 1520.

[0337] For the sake of brevity, some differences of the respiratory therapy accessory 100 relative to the first example are described in detail below. The description regarding the respiratory therapy accessory 100 may additionally apply to the equivalent entirety of this fourth example.

[0338] In this fourth example, the body 1502 has been effectively rotated 90° clockwise about the longitudinal axis of the body 1502 relative to the retaining members when compared to the first example. That is, the first retaining member 1504 extends from the spine 1516 of the body 1502 on a side of the body generally opposite the slot 1522; the second retaining member 1506 extends from the second arm 1514 on a side of the body 1502 generally the same as the slot 1522; and the third retaining member 1508 (which is the longest of the retaining members) extends from the second arm 1514 of the body 1502 on a side of the body 1502 generally the same as the first opening 1518 and generally opposite the second opening 1520. That is, when the respiratory therapy accessory 1500 is viewed from above or below, the third retaining member 1508, the first opening 1518, the second opening 1520, and the longitudinal axis are aligned with one another (e.g., as shown in FIG. 1 ). Fig.18 In other words, third retention member 1308, first opening 1518, and second opening 1520 of respiratory therapy accessory 1500 are each aligned on or bisected by a single plane.

[0339] from Figures 15 to 17 and Fig.19It can be observed that the first retention member 1504, the second retention member 1506 and the third retention member 1508 of this fourth example are each spaced the same distance from the upper end of the body 1502 in the direction of the longitudinal axis of the body 1502. That is, the retention members 1504, 1506, 1508 are each located toward the lower end of the body 1502 and are not spaced apart in the axial direction as in the first example. Therefore, the first arm 1512 at the upper end of the body 1502 is free of any retention members, and the first arm 1512 is therefore less likely to be inadvertently disengaged from the support when a force is applied to any of the retention members during use. However, in other examples, one or more of these retention members may be spaced apart from another retention member in the axial direction of the body 1502, and / or may, for example, extend from the first retention member 1504 as shown in the first example.

[0340] Each of the first retention member 1504, the second retention member 1506, and the third retention member 1508 of this fourth example is supported by a support member in the form of a respective gusset 1524a, 1524b, 1524c, as shown in FIG. Figures 15 to 19 As shown. Each of the gussets 1524a, 1524b, 1524c is a substantially flat member that is radially arranged in a respective vertical plane that passes through the longitudinal axis of the body 1502. The gussets 1524a, 1524b, 1524c are each thinner than the respective handle 1526a, 1526b or the third retaining member 1508, and thereby form a "T"-shaped vertical cross-section therewith. The height of each of the gussets 1524a, 1524b, 1524c (i.e., the vertical distance between the upper and lower edges of the respective gussets) tapers outwardly from the body 1502, as shown. Fig.16 and Fig.17 As best shown, at least a portion of the gusset 1524c can be bent toward the bottom side of the third retention member 1508.

[0341] refer to Fig.17 , the gusset 1524a of the first retention member 1504 extends between the partial annular portion 1528, the bottom side of the first handle 1526a, and the body 1502. More specifically, the gusset 1524a of the first retention member 1504 extends between the proximal end of the partial annular portion 1528, the lower surface of the first handle 1526a, and the body 1502 (e.g., spine 1516) below the handle 1526a. The gusset 1524a has a substantially triangular shape.

[0342] Still reference Fig.17, the gusset 1524b of the second retention member 1506 extends between the proximal end of the retention arm 1530, the lower surface of the second handle 1526b, and the body 1502 (e.g., the second arm 1514) below the handle 1526b. The gusset 1524b also has a substantially triangular shape, similar to the gusset 1524a.

[0343] Return to reference Fig.16 , the gusset 1524c of the third retention member 1508 extends between the lower surface of the third retention member 1508 and the body 1502 (e.g., the second arm 1514) below the third retention member 1508. The gusset 1524c terminates at the distal end of the third retention member 1508 at or near the lowest point of the hook 1532. The profile of the lower edge of the gusset 1524c is determined so that the overall height of the gusset 1524c tapers substantially continuously from the body 1502 toward the hook 1532. In other examples, it may be a partial taper of one or more of the gussets 1524a, 1524b, 1524c, or one or more of the gussets may not necessarily be tapered at all.

[0344] In some examples, one or more of the gussets 1524a, 1524b, 1524c can extend from the upper side of the handle or retention member to the outer surface of the body 1502 immediately above the handle or retention member. In other examples, one or more of the gussets 1524a, 1524b, 1524c can be omitted. For example, in examples where one or both of the handles 1526a, 1526b are omitted, one or both of the gussets 1524a, 1524b can be omitted.

[0345] The gussets described herein can strengthen the corresponding retention members and reduce the possibility of damage or breakage due to excessive forces on the retention members, and / or allow for a reduction in the cross-section of the handle or third retention member. Figure 1 The equivalent cross section of the first example shown (which can be measured to be approximately 72 mm 2 ), the cross-sectional area of ​​each of the handles 1526a, 1526b and the third retention member 1508 of this fourth example (measured as approximately 48 mm 2 ) is reduced. The handles 1526a, 1526b and the third retaining member 1508 also have a high aspect ratio. For example, the third retaining member 1508 has an aspect ratio of about 3:1 in cross section, but can be between about 2:1 and 4:1 in other examples. By way of comparison, the third retaining member 108 of the first example can have an aspect ratio of about 1.15:1. It should be understood that other examples described and illustrated herein can be modified to similarly include gussets.

[0346] Special reference Fig.15 and Fig.16 , the third retention member 1508 (or at least its upper surface) initially extends substantially vertically from the body 1502, then bends downwardly, and then bends in an upward direction to terminate at the hook 1532 at the distal end of the third retention member 1508. This arrangement can advantageously facilitate the patient interface assembly or product packaging retainer to be positioned at a low point of the third retention member 1508, near the distal end, by the third retention member 1508, separating the patient interface assembly or product packaging from the first retention member 1504 and / or the second retention member 1506. In some examples, the third retention member 1508 can omit the hook 1532. In some examples, the third retention member 1508 may not initially extend vertically from the body 1502. For example, the third retention member 1508 can extend directly downward from the body 1502, similar to the example of Figure 1 and Figure 4 The third retention member 108 of the first example is shown.

[0347] The shape of the third retaining member 1508 is determined so that the width of the third retaining member 1508 (in the horizontal direction, as shown) is greater than the thickness of the third retaining member 1508 (in the vertical direction, as shown). That is, the third retaining member 1508 can have a horizontal, generally flat rectangular or elliptical cross-section. The third retaining member 1508, in particular the hook portion 1532, can be configured to be received in a "Euro slot" hanging piece (or similar aperture) formed in the product packaging. In particular, the third retaining member 1508 can have a horizontally elongated cross-section having parallel upper and lower surfaces and a rounded end with a radius equal to half the thickness of the third retaining member 1308. The gusset 1524c can advantageously prevent or inhibit movement of the product package toward the proximal end of the third retaining member 1508 (e.g., beyond the midpoint of the third retaining member 1508) to maintain the spacing between the product package and the first retaining member 1504 and the second retaining member 1506. For example, hook portion 1532 can be further configured to retain other respiratory therapy components such as a mask, as described above with respect to the first example.

[0348] Reference again Fig.17, the body 1502 of this fourth example includes a thickened region 1702 that is thicker in the circumferential direction than adjacent portions of the body 1502. The thickened region 1702 is positioned on the spine 1516, between the first arm 1512 and the second arm 1514. As shown, the thickened region 1702 of the respiratory therapy accessory 1500 is positioned approximately opposite the slot 1522. The thickened region 1702 in this fourth example varies in thickness along the longitudinal direction and the circumferential direction. That is, the thickness of the body 1502 in the thickened region 1702 is not uniform in either the longitudinal direction or the circumferential direction, but is at least thicker in the circumferential direction than adjacent regions of the body 1502 outside of the thickened region 1702. In the fourth example, the thickened region 1702 is thickest where the first retaining member 1504 extends from the body 1502. In the fourth example, the thickened region 1702 tapers continuously from this thickest region adjacent to the first retention member 1504 toward the opposite end of the body 1502, but in other examples, the thickened region may include one or more abrupt thickness step changes in the direction of the longitudinal axis. The thickened region 1702 extends substantially the full length of the body 1502 in the longitudinal direction, but partially extends around the circumference of the body 1502. However, in some examples, the thickened region 1702 may extend partially along the full length of the body 1502 in the longitudinal direction. For example, the thickened region 1702 may extend approximately half the length from the first retention member 1504 toward each end of the body 1502. The thickened region 1702 similarly tapers smoothly in the circumferential direction, but may alternatively include one or more abrupt thickness changes.

[0349] The thickened region 1702 may strengthen the body 1502 to compensate for material removal to create the slot 1522 and / or mitigate the effects of material creep, thereby ensuring that the body 1502 has sufficient rigidity to securely engage a support member during use.

[0350] The thickened area 1702 in this fourth example is defined by a change in the profile of the outer surface of the body 1502. That is, the inner surface of the body 1502 remains substantially cylindrical during use so as to provide stable engagement with the support 602.

[0351] refer to Fig.18 When viewed along the longitudinal axis, the first retaining member 1504, the second retaining member 1506, and the third retaining member 1508 extend in a direction spanning an angle of less than 180°, for example, about 140°, relative to the longitudinal axis. The third retaining member 1508 bisects the angle defined between the first retaining member 1504 and the second retaining member 1506. That is, the acute angle between the first retaining member 1504 and the third retaining member 1508 is equal to the acute angle between the second retaining member 1506 and the third retaining member 1508.

[0352] FIG. 20A to FIG. 20C The fourth example respiratory therapy accessory 1500 is shown in various stages of engagement with the support 602 during use. The engagement of the respiratory therapy accessory 1500 is similar to that described above with respect to FIG. 6A to FIG. 6D However, in brief, the respiratory therapy accessory 1500 is first rotated to align the slot 1522 with the support 602 and translated so that the support 602 is aligned as described above. Fig. 20A The slot 1522 is shown to receive and be partially located within the interior space 1510.

[0353] In order to engage the first arm 1512 and the second arm 1514 with the support 602 to securely attach the body 1502 to the support 602, the body 1502 is Fig. 20B 1502. The rotation may be achieved by pulling the third retaining member 1508 downward in the direction of arrow 2002. That is, the third retaining member 1508 effectively acts as a lever to rotate the body 1502, which may provide a mechanical advantage during engagement of the first arm 1512 and the second arm 1514 with the support 602. The respiratory therapy accessory 1500 rotates about an axis of rotation that is substantially perpendicular to the longitudinal axis of the third retaining member 1508 and / or the body 1502. The axis of rotation may pass through the slot 1522.

[0354] Rotation of the respiratory therapy accessory 1500 causes the first arm 1512 and the second arm 1514 to elastically deform around the circumference of the support 602 and then recover to "snap" the respiratory therapy accessory 1500 onto the support 602 and secure it in place, further (e.g., completely) receiving the support 602 within the interior space 1510, as shown. Fig. 20C shown.

[0355] To remove the respiratory therapy accessory 1500 from the support 602, the above steps can be reversed. That is, the first arm 1512 and the second arm 1514 are first disengaged from the support 602 by: moving in an upward direction (with respect to the support 602) and then moving in an upward direction (with respect to the support 602). Fig. 20B The third retaining member 1508 is moved (in the opposite direction of the arrow 2002 in FIG. 1 ) to rotate the third retaining member 1308 about the rotation axis, and then the respiratory therapy accessory 1500 is translated to one side so that the support member 602 leaves the internal space 1510 through the slot 1522.

[0356] Fifth example

[0357] Fig.21A respiratory therapy accessory 2100 according to a fifth example is shown. The respiratory therapy accessory 2100 includes a body 2102 configured to be coupled to the support 602. The body 2102 has a longitudinal axis 2104. The body 2102 is similar to the body 102 described above with respect to the respiratory therapy accessory 100, and is similarly configured to be clipped to the support by translation and rotation. However, other attachment mechanisms may be used in alternative examples.

[0358] The respiratory therapy accessory 2100 includes a plurality of elongated arms 2106, in this particular example, three elongated arms 2106, radiating away from the body 2102. In other examples, the respiratory therapy accessory 2100 can have fewer than or more than three elongated arms 2106, for example, two arms, or four or more arms. In this fifth example, the elongated arms 2106 are collectively opposite to the slots of the body 2102.

[0359] The central elongated arm 2106 of the respiratory therapy accessory 2100 extends substantially radially relative to the longitudinal axis 2104. However, in this fifth example, the two outer elongated arms 2106 extend from the body 2102 in a non-radial direction.

[0360] In this fifth example, the divergence angles between each of two adjacent pairs of the three elongated arms 2106 are equal. That is, the central elongated arm 2106 bisects the two outer elongated arms 2106. However, in some examples, the angle between one pair of elongated arms 2106 can be different from the angle between at least another pair of elongated arms 2106.

[0361] The angle spanned by the plurality of elongated arms 2106 in this fifth example is less than 90°. That is, the angle spanned by the outermost elongated arms 2106 of the plurality of elongated arms 2106 is less than 90°. However, in some examples, the angle spanned by the plurality of elongated arms 2106 may be less than 120°, less than 150°, or equal to or less than 180°. That is, the angle spanned by the outermost elongated arms of the plurality of elongated arms 2106 may be equal to or less than 180°.

[0362] The angle spanned by these elongated arms 2106 is measured as described above with respect to the first example. However, since the elongated arms 2106 of this fifth example may not all extend radially from the body 2102, it should be understood that the axes passing through the elongated arms do not intersect at the longitudinal axis of the body 2102. In some variations of this fifth example, it is also possible that the axes passing through the elongated arms 2106 may not all intersect at a common point. In such a case, the angle between the axes of the two outermost elongated arms 2106 will be measured.

[0363] When viewed from the side, the plurality of elongated arms 2106 in this fifth example extend perpendicularly from the body 2102. That is, the plurality of elongated arms 2106 extend from the body 2102 in a plane that is perpendicular to the longitudinal axis 2104 of the body 2102. If the longitudinal axis 2104 is vertical, the elongated arms 2106 will therefore extend substantially horizontally. However, in some examples, the plurality of elongated arms 2106 may extend from the longitudinal axis 2104 of the body 2102 at an angle that is not perpendicular to the longitudinal axis 2104. That is, the elongated arms 2106 may be angled upward or downward, and / or may be curved.

[0364] An interior space 2108 is defined between each of the three adjacent pairs of elongated arms 2106. A partial annular portion 2110 is defined by the proximal ends of a pair of adjacent elongated arms 2106. Each of the partial annular portions 2110 defines a first proximal portion of the corresponding interior space 2108.

[0365] The local annular portion 2110 has a local annular boss 2112. The local annular boss 2112 can be configured to support a respiratory therapy component. The respiratory therapy component can be a patient interface assembly for delivering respiratory gas to a patient. The patient interface assembly can be configured for nasal high flow therapy. The patient interface assembly can be a non-sealed nasal cannula assembly. The nasal cannula assembly can include a nasal cannula with a fork for inserting into the patient's nostrils, a conduit that is fluidly connected to the nasal cannula at one end to deliver a flow of respiratory gas to the patient through the nasal cannula, and a connector attached to the opposite end of the conduit for connection with a respiratory conduit, which is configured to deliver a flow of respiratory gas from a respiratory humidifier, a ventilator, etc. to the conduit. The humidifier can be integrated with a blower. The local annular boss can be configured alternatively or additionally to support a respiratory conduit.

[0366] The illustrated partial annular protrusion 2112 of the respiratory therapy accessory 2100 is configured to abut against a shoulder of a connector of a respiratory catheter, similar to the above specifically referenced Figure 8 The boss 714 described with respect to the respiratory therapy accessory 100. The partial annular portion 2110 and the partial annular boss 2112 are similarly configured to receive and retain the connector of the nasal cannula assembly. For example, the nasal cannula assembly can be an Optiflow™+ or an Optiflow™ 3S. In other examples, the partial annular portions 2110 can each be configured to retain a different respiratory therapy component. That is, the size and / or shape of the partial annular portions 2110 can be different.

[0367] The partial annular boss 2112 is spaced apart from the top surface of the partial annular portion 2110. An arcuate wall 716 is defined between the partial annular boss 2112 and the top surface of the partial annular portion 2110, similar to the arcuate wall 716 of the respiratory therapy accessory 100. The arcuate wall extends through an angle greater than 180°. The arcuate wall is configured to partially surround the connector and reduce lateral movement of the connector during use. The connector can be bridged by the combination of the partial annular boss 2112 and the arcuate wall, similar to Figure 8 As shown in .

[0368] In some examples, the partial annular protrusion 2112 can be positioned halfway between the top surface of the partial annular portion 2110 and the bottom surface of the partial annular portion 2110. In some examples, the partial annular protrusion 2112 forms the bottom surface of the partial annular portion 2110. In other examples, the partial annular protrusion 2112 can be omitted, and the connector can be configured to abut against the top surface of the partial annular portion 2110.

[0369] The elongated arms 2106 of the respiratory therapy accessory 2100 each include a linear protrusion 2114 that is configured to at least partially support one or more respiratory therapy components, particularly one or more respiratory catheters. For example, the elongated arms 2106 can be configured to hold a first respiratory catheter having a first maximum outer diameter and / or a minimum outer diameter, and a second respiratory catheter having a second maximum outer diameter and / or a minimum outer diameter that is smaller than the corresponding first diameter of the first respiratory catheter. In another example, the first respiratory catheter can be suitable for adults or NIV treatment, while the second respiratory catheter having a relatively smaller maximum outer diameter and / or minimum outer diameter 1004 can be suitable for infants and / or pediatric patients, or adult NHF treatment. The respiratory catheter can be part of a double-limb circuit including an inspiratory catheter, an expiratory catheter, and a Y-piece.

[0370] The linear projection 2114 extends from adjacent the partial annular portion 2110 toward the distal end of the corresponding elongated arm 2106. In other examples, the projection need not be linear, but can be curvilinear, for example.

[0371] The linear protrusion 2114 can be configured to engage the corrugations or undulations of a breathing tube, or the linear protrusion 2114 can be configured to grip a breathing tube having a relatively smooth outer surface. The linear protrusion 2114 can be sized to correspond generally to the outer surface of at least one breathing tube. That is, the linear protrusion 2114 can have a generally parabolic cross-section and extend from the elongated arm 2106 a distance that generally corresponds to the depth of the corrugations in the breathing tube, for example, Fig.10 The valley of the corrugated portion 1010 of the inhalation tube 1008.

[0372] The linear protrusions 2114 of the respiratory therapy accessory 2100 extend perpendicularly from the respective elongated arms 2106. However, in some examples, the linear protrusions 2114 may extend at an acute angle from the respective elongated arms 2106. In some examples, the linear protrusions 2114 may taper in a direction toward the distal end of the respective elongated arms 2106.

[0373] The divergence of the elongated arms 2106 may advantageously enable the respiratory therapy accessory 2100 to receive and secure respiratory tubes of a variety of different diameters.

[0374] The plurality of elongated arms 2106 of the respiratory therapy accessory 2100 can each further include a protrusion 2116 extending into the corresponding interior space 2108. The protrusion 2116 can be configured to help retain the respiratory tube within a defined area of ​​the interior space 2108. The protrusion 2116 can prevent or at least reduce the likelihood that the respiratory tube will inadvertently disengage from the linear protrusion 2114 and fall to the ground. The protrusion 2116 can prevent or at least reduce the likelihood that two respiratory tubes retained by the respiratory therapy accessory 2100 will contact each other.

[0375] The protrusion 2116 can intersect the linear protrusion 2114. The protrusion 2116 in the respiratory therapy accessory 2100 is perpendicular to the linear protrusion 2114. That is, the protrusion 2116 intersects the linear protrusion 2114 at a 90° angle. However, in some examples, the protrusion 2116 can be spaced apart from the linear protrusion 2114 so that they do not have to intersect.

[0376] In this fifth example, the protrusions 2116 of the respiratory therapy accessory 2100 extend further into the interior space 2108 than the linear bosses 2114. The protrusions 2116 are arranged in pairs relative to each other, defining a waist region therebetween, which can be narrower than the diameter of the selected respiratory catheter. The elastically deformable respiratory catheter deforms and elastically recovers when it is forced through one or more waist regions. The corrugated portion of the respiratory catheter can engage with a pair of opposing linear bosses 2114 to retain the respiratory catheter between the corresponding pair of elongated arms 2106.

[0377] The distal end of the elongated arm 2106 (in this example, each elongated arm 2106) includes a hook portion 2118. The hook portion 2118 is configured to retain a respiratory therapy component such as a patient interface assembly. The hook portion 2118 can be configured to retain a respiratory therapy component, similar to the above with specific reference to Figure 1 and Figure 4The hook 122 described with respect to the third retaining member 108 of the respiratory therapy accessory 100. The respiratory therapy component may be a patient interface assembly configured for invasive, NIV or NHF therapy. The patient interface assembly may be a full face mask, a full face mask, an oronasal mask, a nasal mask, a nasal pillow mask, a nasal cannula assembly, an endotracheal tube, a tracheostomy tube, or any other patient interface assembly suitable for respiratory therapy. In some examples, the hook 2118 may be configured to alternatively or additionally retain a product package containing a patient interface assembly. The package may have an orifice for receiving the hook 2118. The distal end of the hook 2118 may optionally include an enlarged portion as described above with respect to the respiratory therapy accessory 100. The hook 2118 and / or the elongated arm 2106 may further include a recessed portion (not shown) to position the patient interface assembly and prevent the patient interface assembly from accidentally moving along the elongated arm 2106 toward the body 2102 and / or the distal end of the hook 2118.

[0378] Sixth Example

[0379] Fig. 22 A sixth example of a respiratory therapy accessory 2200 is shown. This sixth example is generally similar to the respiratory therapy accessory 2100 of the fifth example. For the sake of brevity, some differences will be described in detail below. The description of the respiratory therapy accessory 2100 of the fifth example can also be applied to the equivalent entirety of this sixth example.

[0380] Respiratory therapy accessory 2200 includes a body 2202 for attachment to a support. In this sixth example, four elongated arms 2204 extend from body 2202. The elongated arms 2204 span an angle of less than 90° (when viewed from above or below along the longitudinal axis of body 2202) from an imaginary intersection of a line passing through the two outermost elongated arms 2204.

[0381] The elongated arms 2204 of the respiratory therapy accessory 2200 each include a hook portion 2206 that defines a recess 2208. The recess 2208 can prevent a respiratory therapy component suspended from the hook portion 2206 from inadvertently sliding out of the hook portion and / or out of the distal end of the hook portion toward the body 2202.

[0382] The linear protrusion 2210 extends at an angle along the plurality of elongated arms 2204. That is, the linear protrusion 2210 is angled upward from the proximal end toward the distal end of the elongated arms 2204. This can be helpful in improving or preventing the breathing tube from inadvertently moving in the distal direction and possibly moving out. The linear protrusion 2210 in this sixth example also extends around a partial annular portion defined between the proximal ends of the elongated arms 2204.

[0383] Each protrusion 2212 of the respiratory therapy accessory 2200 is asymmetrical, providing a relatively shallow angle for the entry of a respiratory catheter between a pair of adjacent elongated arms 2204 in a direction toward the body 2202, and providing a relatively steep angle for the removal of the respiratory catheter in a direction toward the distal ends of the pair of adjacent elongated arms 2204. The resistance provided by the asymmetrical protrusion 2212 when inserting the respiratory catheter can be advantageously relatively lower than when removing the respiratory catheter.

[0384] It should be understood that one or more features of any of the above examples may be combined with one or more features of the other examples. By way of example, the third retaining member 1508 of the fourth example may replace the third retaining member 108 of the first example, the third retaining member 1308 of the second example, or the third retaining member 1408 of the third example; the second retaining member 106 of the first example may replace the second retaining member 1306 of the second example, the second retaining member 1406 of the third example, or the second retaining member 1506 of the fourth example; and / or two or more of the elongated arm 2106 of the fifth example or the elongated arm 2204 of the sixth example may replace the third retaining member 108 of the first example, the third retaining member 1308 of the second example, the third retaining member 1408 of the third example, or the third retaining member 1508 of the fourth example.

[0385] Changing the modality of respiratory therapy

[0386] Patients may wish to change between NIV and NHF therapy periodically or intermittently. For example, it has been found that intermittent use of NHF therapy can benefit the recovery of patients receiving NIV therapy. Alternatively or additionally, patient interface assemblies for NHF therapy are generally less invasive than NIV interface assemblies, thereby allowing patients to eat and / or communicate more freely with medical professionals and visitors.

[0387] Use of the disclosed respiratory therapy accessories can advantageously reduce confusion or complications for a patient during a change or alternation between different forms of respiratory therapy. Use of the disclosed respiratory therapy accessories can also advantageously avoid or mitigate one or more of the inconvenience of finding a suitable place to place various respiratory therapy components, the risk of respiratory therapy components falling to the floor, and / or potential contamination. Use of the disclosed respiratory therapy accessories will be described in more detail below with reference to non-limiting example procedures and a first example respiratory therapy accessory 100.

[0388] In one example process, a patient can change or alternate between NIV therapy and NHF therapy. During NIV therapy, a gas source such as a ventilator can be used to deliver gas to the patient. The same gas source can also have an NHF mode configured to provide NHF therapy.

[0389] The patient may already be receiving NIV therapy, wearing a first patient interface assembly configured for NIV therapy, and will be converted to NHF therapy. The first patient interface assembly can be a full face mask (configured to seal around the patient's eyes, nose and mouth), a full face mask (configured to seal around the patient's nose and mouth), an oronasal mask (seals with or around each of the patient's nose / nostrils and mouth individually), a nasal mask (configured to seal around the patient's nose), a nasal pillow mask (configured to seal with the patient's nostrils), or any other patient interface assembly suitable for use in NIV therapy. The first patient interface assembly will generally be connected to a single-limb circuit (if the first patient interface assembly is not exhausted, the exhalation port is consistent with the first patient interface assembly), but in some cases may be connected to a double-limb circuit. Prior to converting to NHF therapy, the respiratory therapy accessory 100 is attached to the support. The first retaining member 104 of the respiratory therapy accessory 100 can retain a second patient interface assembly configured for NHF therapy. For example, the second patient interface assembly can be a non-sealing nasal cannula assembly, such as the Optiflow™+ nasal cannula assembly 802 or the Optiflow™ 3S nasal cannula assembly. Alternatively, the third retaining member 108 of the respiratory therapy accessory 100 can hold a package containing the second patient interface assembly. In some cases, the second patient interface assembly is not necessarily held by the first retaining member 104, but can be placed near the patient, such as next to the patient's face or on the patient's bed.

[0390] To switch to NHF therapy, the first patient interface assembly can be removed from the patient's face and hung from respiratory therapy accessory 100 for storage, such as from hook 122 of third retention member 108. The second patient interface assembly can be removed from first retention member 104 and placed on the patient's face.

[0391] The second patient interface assembly will in most cases be used with a single-limb circuit. The inspiratory conduit can be removed from the first patient interface assembly and, if desired, temporarily retained by the second retaining member 106 before it is attached to the second patient interface assembly (via an adapter, if desired). In other cases, a different inspiratory conduit and / or a different gas source may be used.

[0392] In some cases, the NIV circuit can be a dual-limb circuit. The inspiratory conduit can be removed from the expiratory conduit and the Y-piece and connected to a second patient interface assembly. The expiratory conduit and the Y-piece can be suspended from the second retaining member 106 of the respiratory therapy accessory 100.

[0393] In some cases, the NIV circuit and the NHF circuit may use different inspiratory catheters. For example, the NIV circuit may be a double-limb circuit, and the NHF circuit may be a single-limb circuit with a different inspiratory catheter. In this case, the NIV circuit and the NHF circuit will typically use different gas sources.

[0394] In some cases, both NIV and NHF therapy can use a two-limb circuit. The second patient interface assembly can be configured to be directly or indirectly connected to the same two-limb arrangement as the first patient interface assembly, and therefore connected to the same gas source. In this case, the gas source can block the expiratory port to which the expiratory conduit is connected, thereby preventing gas from returning to the gas source or bypassing the patient through the Y-shaped tube.

[0395] A gas source configured for NIV therapy can be turned off or placed in standby mode after the first patient interface assembly is removed from the patient. A gas source configured for NHF therapy can be turned on before or after the second patient interface assembly is placed on the patient's face. As noted above, a gas source can be configured for both NIV therapy and NHF therapy. In such an example, the gas source can be changed from a mode suitable for NIV therapy to a mode suitable for NHF therapy. In other cases, different gas sources can be used for NIV and NHF therapy.

[0396] In other cases, the patient may already be receiving NHF therapy, wearing a second patient interface assembly, and is about to switch to NIV therapy. Before switching to NIV therapy, the third retaining member 108 may have held a first patient interface assembly suitable for NIV therapy or a package containing a first patient interface assembly.

[0397] In order to switch to NIV treatment, the second patient interface assembly can be removed from the patient's face and suspended on the first retaining member 104. The first patient interface assembly can then be placed on the patient's face. In some examples, a breathing conduit configured to deliver gas to the patient through the first patient interface assembly can be connected to the first patient interface assembly before or after the first patient interface assembly is placed on the patient's face. In other examples, the first patient interface assembly can be connected to a dual-limb circuit. The dual-limb circuit can be configured to be connected to both the first patient interface assembly and the second patient interface assembly. A gas source configured for NHF treatment can be turned off after the second patient interface assembly is removed from the patient's face. A gas source configured for NIV treatment can be turned on before or after the first patient interface assembly is placed on the patient's face. As noted above, in some examples, a gas source can be configured for both NIV treatment and NHF treatment. In such an example, the gas source can be changed from a mode suitable for NHF treatment to a mode suitable for NIV treatment.

[0398] In another example process, a patient may change or alternate between invasive ventilation therapy and NHF therapy. The patient may already be receiving invasive ventilation therapy and is about to switch to NHF therapy. The patient may be equipped with a third patient interface assembly, such as an endotracheal tube or a tracheostomy tube through an intubation tube. The third patient interface assembly may be connected to a double limb circuit. Before switching to NHF therapy, the first retaining member 104 may hold the second patient interface assembly. Alternatively, the third retaining member 108 may hold a package containing the second patient interface assembly, such as the RT481 post-extubation kit available from Fisher & Paykel Healthcare in Auckland, New Zealand. The second retaining member 106 may hold a suction catheter configured to be connected to the second patient interface assembly. For example, the second retaining member 106 may include the above-mentioned boss 908, which engages with the corrugated or undulating portion of the suction catheter.

[0399] In order to switch from invasive ventilation therapy to NHF therapy, the patient can be extubated. That is, the third patient interface assembly is removed from the patient and can be discarded. The second patient interface assembly can then be placed on the patient's face. The same inspiratory catheter of the double-limb circuit can be used during both invasive ventilation therapy and NHF therapy. The second patient interface assembly will usually be connected to the single-limb circuit. The inspiratory catheter can therefore be removed from the double-limb circuit and fluidly connected to the second patient interface assembly and the expiratory catheter and Y-piece placed on the respiratory therapy accessory 100. The third retaining member 108 can hold the Y-piece. Additionally and / or alternatively, the second retaining member 106 can hold the expiratory catheter. However, in some cases, the second patient interface assembly can be connected to the same double-limb circuit connected to the third patient interface assembly, in which case the third patient interface assembly can be replaced with the second patient interface assembly. The second patient interface assembly can alternatively be connected to the second gas source through different inspiratory catheters (if necessary, through adapters). The second patient interface assembly can alternatively be connected to the same gas source through different inspiratory catheters. Different inspiratory catheters may be held ready for use on respiratory therapy accessory 100 .

[0400] Based on the above, it should be understood that the disclosed respiratory therapy accessories can advantageously provide convenient storage of various patient interfaces and / or respiratory conduits for non-invasive therapy, nasal high flow therapy, and / or invasive ventilation therapy. The disclosed respiratory therapy accessories can facilitate conversion between two different forms of respiratory therapy.

[0401] This application claims the benefit of and priority to Australian Patent Application No. 2021221574 filed on August 25, 2021 and U.S. Provisional Patent Application No. 63 / 269,535 filed on March 17, 2022.
