Description

Technical Field

[0001] The present invention relates to the field of ventilation therapy equipment, and more specifically, to a patient interface fixation patch for securing a ventilation interface device or monitoring element in a predetermined wearing position. Furthermore, the present invention also relates to a ventilation interface device including the patient interface fixation patch and a ventilation therapy device including the ventilation interface device. Background Art

[0002] In recent years, with the increasing maturity of non-invasive respiratory support technology, non-invasive ventilation therapy has become an important treatment for early-stage chronic respiratory failure and chronic obstructive pulmonary disease. Non-invasive ventilation therapy devices include a ventilation interface device worn on the patient's face. These devices typically include nasal masks, oronasal masks, nasal pillows, nasal oxygen cannula, full-face masks, and other respiratory masks. During treatment, oxygen-containing gas provided by the non-invasive respiratory support device is delivered to the patient's airway through the ventilation interface device.

[0003] Taking the nasal oxygen cannula as an example, it includes a nasal prong tube structure for inserting into the patient's nostrils to supply respiratory airflow to the patient through the nasal cavity. Compared with other types of respiratory masks, nasal oxygen cannula has the advantages of small size, flexible movement and comfortable wearing, and is therefore more easily accepted by patients. Usually, it is necessary to use a mechanical fixing structure such as a headband to fix the nasal oxygen cannula to the predetermined wearing position on the patient's head to ensure that the nasal oxygen cannula is worn stably. However, for some special patient groups such as infants and young children, the compressive effect of the headband can easily damage the infant's undeveloped head tissue, and wearing the headband for a long time may cause unbearable discomfort.

[0004] To this end, the prior art has proposed a solution of fixing the nasal oxygen cannula in the wearing position by means of facial adhesive. Since it is flexible to wear, easy to operate and relatively comfortable, it is suitable for patients such as infants and young children. This type of fixing structure usually adopts a facial fixing patch for sticking to the patient's face, and the ventilation interface device is fixed to the facial fixing patch by a connecting medium such as Velcro to facilitate position adjustment and repeated sticking and tearing. However, the structure of connecting media such as Velcro is relatively complex and has poor compliance to the patient's face, resulting in poor wearing comfort; and when the ventilation interface device is torn off, a relatively large pressing force needs to be applied to the facial fixing patch to prevent it from falling off the patient's face, which causes the patient's face to be pressed and feel uncomfortable. Utility Model Content

[0005] The purpose of the utility model is to overcome the problem of poor wearing comfort caused by poor compliance of facial fixation patches to the patient's face in the prior art, and to provide a patient interface fixation patch that can avoid the problem of poor compliance to the patient's face due to the complex structure of the connecting medium, thereby effectively improving wearing comfort.

[0006] In order to achieve the above-mentioned objectives, the present invention provides, on the one hand, a patient interface fixing patch, comprising a user-end patch and an interface-end patch, wherein one side of the user-end patch can be glued to the user's skin surface, and the interface-end patch is glued to the other side of the user-end patch, and allows the ventilation interface device body or monitoring element to be removably glued to the side of the interface end patch facing away from the user-end patch, so as to fix the ventilation interface device body or monitoring element in a predetermined wearing position.

[0007] Preferably, the side of the user-end patch for adhering to the user's skin surface has an adhesive layer and is formed as a single-sided adhesive patch; the two sides of the interface-end patch can be respectively adhered to the user-end patch and the ventilation interface device body or monitoring element.

[0008] Preferably, the size of the interface end patch in any extension direction is smaller than the size of the user end patch in the corresponding extension direction.

[0009] Preferably, the outer contour edge of the user-end patch surrounds the outer contour edge of the interface-end patch.

[0010] Preferably, one side of the user-end patch and the interface-end patch are configured so that: the bonding force between the ventilation interface device body or the monitoring element and the interface-end patch is smaller than the bonding force between the interface-end patch and the user-end patch and the bonding force between the user-end patch and the user's skin.

[0011] Preferably, the interface end patch is configured to allow the ventilation interface device body or monitoring element to be repeatedly pasted no less than 10 times.

[0012] Preferably, the ventilation interface device body or monitoring element has an interface device patch for being removably adhered to the interface end patch, and the size of one side surface of the interface device patch for being adhered to the interface end patch in at least one direction is larger than the size of the interface end patch in that direction.

[0013] Preferably, the user-end patch is made of silicone, and the interface-end patch is made of adhesive.

[0014] A second aspect of the present invention provides a ventilation interface device for ventilation therapy equipment, comprising a ventilation interface device body for supplying air to a user and the above-mentioned patient interface fixing patch for fixing the ventilation interface device body to a predetermined wearing position.

[0015] A third aspect of the present invention provides a ventilation therapy device, comprising a ventilation therapy device host and the above-mentioned ventilation interface device connected to the ventilation therapy device host.

[0016] Through the above technical solution, the patient interface fixing patch of the present invention can be adhered to the user's skin surface through the user end patch, and then the ventilation interface device body or other monitoring elements, such as a nasal prong structure, can be adhered to the interface end patch to fix it in a predetermined wearing position. The user can adjust the position and repeatedly wear and remove it as needed, reducing the tearing pain caused by repeatedly removing it from the patient's skin surface. By configuring the interface end patch to allow the ventilation interface device body or monitoring element to be removably adhered thereto, the interface end patch can have higher flexibility than connecting media such as Velcro, thereby allowing the patient interface fixing patch to better adapt to the patient's facial expression changes and other movements, thereby effectively improving wearing comfort.

[0027] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0028] Reference Figures 1 to 8 As shown, one aspect of the present invention provides a patient interface fixing patch 1 for fixing a respiratory mask or a monitoring element (such as a non-contact vital signs monitoring element) such as a nasal oxygen cannula to a predetermined wearing position on the patient's body. Therefore, although the following will mainly use nasal oxygen cannula as an example to explain in detail the application of the patient interface fixing patch of the present invention and the ventilation interface device including the patient interface fixing patch, the ventilation interface device can also be other types of respiratory masks, such as nasal masks, oronasal masks, nasal pillows, full-face masks, etc. The patient interface fixing patch can be used to fix it to the patient's face so as to provide breathing gas to the patient through the mouth and nose. In addition, the provided patient interface fixing patch can also be used to fix the monitoring element to an appropriate position on the patient's body, such as by affixing it to the chest to monitor vital signs such as heartbeat and respiratory rate.

[0029] Figure 1 The figure shows a schematic diagram of the structure of a nasal oxygen tube. Figures 2 to 4 An enlarged view and a projection view of the nasal prong body and the patient interface fixing patch are shown respectively. The nasal oxygen tube includes a connector 6 for connecting to a ventilation therapy device host (such as a ventilator host), a nasal prong body 3 having a nasal prong tube structure for inserting into the patient's nostrils, a gas duct 4 connected between the nasal prong body 3 and the connector 6, and a patient interface fixing patch 1 provided by the present invention, which will be described in detail later, wherein the gas duct 4 may have an adjustable slider 5 to constrain the gas duct 4. Since the nasal prong body 3 usually spans the patient's philtrum (the nasal plug is inserted into the nasal cavity) and is respectively connected to a gas duct 4 at both ends, the nasal oxygen tube can have a pair of symmetrically arranged patient interface fixing patches 1 so as to fit respectively to the cheeks on both sides of the nose for stable fixation. Among them, a sheet-like interface device patch 2 can be formed on the nasal prong body 3 to connect to the patient interface fixing patch 1.

[0030] like Figures 5 to 8 As shown, the patient interface fixation patch 1 of the present invention includes a user-end patch 11 and an interface-end patch 12, wherein one side of the user-end patch 11 can be glued to the user's skin surface, such as on the patient's face; the interface-end patch 12 is glued to the other side of the user-end patch 11, and allows the ventilation interface device body or monitoring element to be removably glued to the side of the interface-end patch 12 facing away from the user-end patch 11, so as to fix the ventilation interface device body or monitoring element in a predetermined wearing position. When the ventilation interface device is a nasal prong tube as described above, its predetermined wearing position is the wearing position where the nasal prong body 3 spans the patient's philtrum and the nasal plug is inserted into the nasal cavity.

[0031] Thus, the patient interface fixation patch 1 can be adhered to the user's skin surface via the user-end patch 11, and then fixed to a predetermined wearing position by adhering the ventilation interface device body or other monitoring elements to the interface-end patch 12. The user can adjust the wearing position as needed and repeatedly wear and remove the device, thereby reducing the tearing pain caused by repeated removal from the patient's skin surface. In particular, by configuring the interface-end patch 12 to allow the ventilation interface device body or monitoring elements to be removably adhered thereto, the interface-end patch 12 can have greater flexibility than connecting media such as Velcro, thereby enabling the patient interface fixation patch 1 of the present invention to better adapt to changes in the patient's facial expressions and other movements, thereby effectively improving wearing comfort.

[0032] According to the above, the user-end patch 11 and the interface-end patch 12 and the adhesive thereon for bonding can be selected to have high flexibility so as to have better compliance. Among them, the side of the user-end patch 11 used for bonding to the user's skin surface can be configured to have an adhesive layer and formed into a single-sided adhesive patch, the side with the adhesive layer is used to bond to the user's skin surface, and the other side is a non-adhesive surface, and the interface-end patch 12 is bonded to the non-adhesive surface. The interface-end patch 12 can be configured as a double-sided adhesive patch, one side of which is bonded to the non-adhesive surface of the user-end patch 11, and the other side can be bonded to the ventilation interface device body or monitoring element, thereby fixing the ventilation interface device body or monitoring element to a position such as the user's face. The user-end patch 11 can be configured to be made of silicone, and the adhesive layer thereon can also be configured to be of a type that is non-damaging to the skin in contact with the skin, so as to avoid damage caused by prolonged contact with the skin surface. In an alternative embodiment, both sides of the user-end patch 11 can have an adhesive layer respectively and form a double-sided adhesive patch, while the interface-end patch 12 is still configured as a double-sided adhesive patch or is configured as a sticky surface only on the side away from the user-end patch 11. By ensuring that there is appropriate adhesion between the ventilation interface device body or monitoring element and the interface-end patch 12 and between the interface-end patch 12 and the user-end patch 11, the operational convenience can be improved, which will be described in detail later.

[0033] It should be understood that the patient interface patch 1 of the present invention can be pre-connected to the ventilation interface device body or monitoring element when not in use, or can be stored independently of the ventilation interface device body or monitoring element. To this end, the adhesive surface of the user-end patch 11 and the side of the interface-end patch 12 facing away from the user-end patch 11 can be covered with release paper. Since the interface-end patch 12 serves only as a connecting medium between the ventilation interface device body or monitoring element and the user-end patch 11, it can be configured as a layer of adhesive material without a base material, such as multiple adhesive tape, to ensure the conformability of the patient interface patch 1 to the patient's face as much as possible.

[0034] If the user-side patch 11 is configured as a single-sided adhesive patch, the user can press on the user-side patch 11 when removing the ventilation interface device or monitoring element to prevent it from being removed. Depending on the usage scenario, the patient interface patch 1 of the present invention can have a variety of different shapes, such as rectangular, circular, elliptical, polygonal, or fan-shaped. Alternatively, the entire patient interface patch 1 or its user-side patch 11 can be a large sheet of material, which can be cut to the desired shape, size, and area.

[0035] To facilitate connection and removal operations, such as Figure 6 and Figure 8 As shown, in a preferred embodiment of the patient interface fixation patch 1 of the present invention, the size of the interface-end patch 12 in any extension direction is smaller than the size of the user-end patch 11 in the corresponding extension direction. This prevents the interface-end patch 12 from directly adhering to the patient's skin, facilitating the interface-end patch 12 to be adhered to the user-end patch 11 with a strong adhesive force. Furthermore, the outer contour edge of the user-end patch 11 surrounds the outer contour edge of the interface-end patch 12, meaning that the interface-end patch 12 completely falls within the contour range of the user-end patch 11. When attaching and detaching the ventilation interface device body or monitoring element, the user-end patch 11 can be pressed on either side, ensuring good ease of use.

[0036] As mentioned above, the ventilation interface device body or monitoring element, such as the nasal prong body 3, can have an interface device patch 2 for being releasably adhered to the interface end patch 12, thereby facilitating connection with the interface end patch 12 via the interface device patch 2 over a relatively large area. Figure 5 、 Figure 7 and Figure 8As shown, in a preferred embodiment, the side surface of the interface device patch 2 used for adhering to the interface end patch 12 is set to be larger than the area of the interface end patch 12, and can be further smaller than the area of the user end patch 11. As a result, when adhering and removing the ventilation interface device body or monitoring element, the operator's (such as medical staff) fingers can easily enter the space between the interface device patch 2 and the user end patch 11 that is not adhered to the interface end patch 12, which not only facilitates the application of appropriate pressure to the user end patch 11, but also prevents their fingers from being adhered to the interface end patch 12 or directly contacting the patient's skin. In order to facilitate the operation of the interface device patch 2 when removing the ventilation interface device body or monitoring element, the side surface of the interface device patch 2 used for adhering to the interface end patch 12 only needs to be larger in at least one direction than the size of the interface end patch 12 in that direction.

[0037] In a more preferred embodiment of the present invention, the user-end patch 11 and the interface-end patch 12 are configured so that: the bonding force between the ventilation interface device body or the monitoring element and the interface-end patch 12 is less than the bonding force between the interface-end patch 12 and the user-end patch 11 and the bonding force between the user-end patch 11 and the user's skin, which can be achieved by selecting adhesives and adhesive materials of appropriate materials. Thus, when removing the ventilation interface device body or the monitoring element, the operator can simply pull the aforementioned interface device patch 2 away from the patient without applying additional pressing force to the user-end patch 11, and can keep the user-end patch 11 and the interface-end patch 12 in their pasted positions. Through this configuration, the problem of the patient feeling uncomfortable due to pressure on the face or being stuck to the user-end patch 11 due to contact with the user-end patch 11 during operation can be avoided, which significantly improves the ease of use and patient comfort.

[0038] Combine Figures 5 to 8 As shown, when the patient uses the nasal oxygen cannula normally, it is fixed by the patient interface fixing patch 1. The patient interface fixing patch 1 is in the form of a film, which ensures a firm adhesion while greatly reducing the space for structural connection, making the operation simpler and the cost lower, and greatly improving the patient's compliance and wearing comfort. When the patient needs to temporarily remove the nasal oxygen cannula (for example, to eat, check, etc.), the outermost edge of the interface device patch 2 can be torn off to separate it from the patient interface fixing patch 1. At this time, the patient interface fixing patch 1 still remains on the patient's face, as shown in FIG. Figure 6As shown. Compared with connection structures such as Velcro, the patient interface fixing patch 1 of the present invention has a simple structure and a small tearing force, which greatly reduces the discomfort caused by pressing on the patient's face during tearing. When the patient uses the nasal oxygen cannula again, the interface device patch 2 can be pasted again with the interface end patch 12 of the patient interface fixing patch 1 to fix it on the patient's face. Among them, the interface end patch 12 is configured to allow the ventilation interface device body or monitoring element to be repeatedly pasted not less than 10 times. For example, when the aforementioned interface device patch 2 is made of plastic elastomer materials such as silicone, TPE, TPU, etc., it can be repeatedly pasted with the interface end patch 12 up to about 50 times.

[0039] On this basis, another aspect of the present invention provides a ventilation interface device for ventilation therapy equipment, such as the above-mentioned nasal oxygen tube, nasal mask, oronasal mask, nasal pillow, full-face mask, etc. The ventilation interface device includes a ventilation interface device body for supplying air to the user and the above-mentioned patient interface fixing patch 1 for fixing the ventilation interface device body to a predetermined wearing position. The patient interface fixing patch 1 can be used to fix different patient interfaces to the skin of the face or other positions.

[0040] In addition, the present invention also provides a ventilation interface device including a ventilation therapy device host and the above-mentioned ventilation interface device connected to the ventilation therapy device host.

[0041] While the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple variations and combinations should also be considered as disclosed in the present invention and fall within the scope of protection of the present invention.
