Abstract
Description
Technical Field
[0001] This invention relates to a respiratory device for at least assisted artificial respiration of a patient. The respiratory device includes:
[0002] -Equipment housing,
[0003] - A functional device housed in a device housing, the functional device comprising, as a functional unit: at least one section of a breathing gas line; a pressure changing device for changing the pressure of the breathing gas in the breathing gas line; and a control device for controlling the operation of at least the pressure changing device; and - an input / output device disposed on the device housing and accessible from outside the device housing for its operation, the input / output device for inputting data and / or control commands to the control device and / or for outputting data and information, wherein the input / output device is connected to the control device in a signal transmission manner. Background Technology
[0004] Preferably, the breathing equipment is an emergency breathing equipment, such as an emergency breathing equipment used by emergency physicians and first responders in emergency situations.
[0005] As such emergency breathing equipment is known, it is manufactured by Fritz Stephan GmbH, located in Gackenbach, Germany, and is named "EVE". IN The breathing equipment and the breathing equipment named "Falco 202Evo" by Siare Engineering International Group, an Italian company located in Valsamoggia, Italy.
[0006] As a portable medical device, but not a respiratory device, it is also known that GS Medical Devices G.Stemple GmbH, located in Kaufering (Germany), has a type name of "corpuls". 3 The defibrillator is a device that is known to pivot within a support that houses the defibrillator in an operating configuration over an angle range of approximately 30°.
[0007] In addition, the applicant’s breathing apparatus, “Hamilton-G5,” is known to have a monitor with an operating panel that is pivotable relative to the rest of the device housing.
[0008] Emergency breathing equipment, also known specifically as "intensive care breathing equipment," is used to rapidly supply breathing gases to patients outside of clinical settings, such as at accident sites or locations and / or during patient transport. While emergency breathing equipment can obviously be used in clinical settings, hospitals typically provide higher-powered breathing equipment as emergency breathing devices.
[0009] As a respiratory device usable outside of clinical settings, emergency breathing equipment, preferably existing breathing equipment, has its own accumulator that enables the emergency breathing equipment to operate independently of the power grid for at least a certain period of time. Furthermore, emergency breathing equipment, preferably existing breathing equipment, is designed to be portable in terms of size and weight, allowing emergency medical personnel, such as emergency doctors called to an accident scene, to move over a distance of tens of meters using only their own muscle strength without excessive physical strain.
[0010] Emergency breathing devices, provided they have a fan as a preferred pressure-changing device, can provide at least ambient air as a breathing gas even without a supplemental special gas reserve, such as a releasably coupled oxygen reserve. The ambient air can be mixed with a special gas different from the ambient air when needed, most often pure oxygen, but also anesthetic and / or therapeutic gases and gas mixtures. For this purpose, emergency breathing devices, such as those of the present invention, typically have a connection structure for connecting a special gas reserve.
[0011] To protect the functional device from external influences such as mechanical impacts and contamination, the functional device is housed within the equipment casing.
[0012] To enable the input / output devices to operate the respiratory equipment and to perceive information about the operational status of the respiratory equipment and / or the respiratory status of the patient breathing through the respiratory equipment, the input / output devices are mounted on the equipment housing, more specifically, such that they are accessible to the operator from outside the equipment housing. Through a signal-based connection between the input / output devices and the control devices, signals can be transmitted between these devices, thereby enabling the transmission of data and information.
[0013] Given the availability of existing respiratory equipment as portable breathing devices at accident sites and in medical transport vehicles (including ground vehicles, aircraft, and watercraft), it is important that the equipment be adaptable to different operating environments and conditions and operate optimally in these diverse environments and conditions. Here, in very rare cases, an ergonomic support surface exists as the working surface for the respiratory equipment. Summary of the Invention
[0014] Therefore, the object of the present invention is to improve the breathing device mentioned at the beginning so that the breathing device can also be used and operate optimally in operating environments that are not prepared for its use.
[0015] This invention achieves this objective through a respiratory device of the type mentioned at the beginning, which has a support in which the device housing and the input / output devices disposed thereon are rotatably housed in the support about a virtual axis of rotation. The support, in principle, ensures the secure placement of the respiratory device at the appropriate location of use. By rotatably housing the device housing together with the input / output devices disposed thereon about the axis of rotation, the entire device, consisting of the device housing and / or the input / output devices, can rotate in an orientation after the support is placed, in which the entire device is not only operable but also as comfortably as possible for artificial respiration of the patient. Therefore, the respiratory device can be placed on the ground at an accident site, or spaced apart from the ground on the hood of a vehicle, or placed in a location existing at the appropriate location of use. In particular, the impact of different operating conditions caused by different possible placement heights on the operator of the respiratory device can be reduced by rotatably housing the device housing in the support. Therefore, the device housing and the input / output devices in the support can be twisted about the axis of rotation, so that the input / output devices are pointed towards the operator.
[0016] Here, the rotatability of the entire device, consisting of the housing and the input / output devices, is preferred over the known relative flip-up of the control panel or control plate (which serves as the input / output device) relative to the rest of the housing, because the breathing apparatus remains compact regardless of the orientation of the entire device. If, instead, the input / output devices were simply flipped open away from the housing towards the operator, the risk of other personnel moving within the operating environment of the breathing apparatus colliding with the flipped-open portion of the apparatus and thus impairing the breathing of the patient requiring artificial respiration increases. Finally, it must be considered that there are diverse and partially uncoordinated rescue personnel, such as emergency physicians and paramedics, firefighters and police officers, and, when necessary, civilian first responders, especially in a hurried manner at the accident site. Many of these individuals, focused on their respective tasks, may overlook the breathing apparatus in use. Therefore, the more compact the breathing apparatus, the safer its operation, even under exceptional conditions of panic.
[0017] While the possibility that the input / output devices can be movable relative to the device housing should not be excluded, the device housing is preferably housed on a bracket together with the input / output devices in a manner rotatable about a rotation axis. Preferably, the input / output devices are rigidly, i.e., immovably mounted on the device housing relative to the device housing.
[0018] For forming the most compact device housing while occupying the smallest possible space volume while maintaining full functionality, it has proven advantageous for the device housing to have a prismatic structure extending along the prism axis. This prismatic structure includes an outer casing wall that surrounds the prism axis radially spaced apart from it. Preferably, the axis of rotation extends collinearly with and parallel to the prism axis, spaced apart from it. This has the advantage that the volume area swept by the device housing, along with the input / output devices, as a movement space when rotating about the axis of rotation is small compared to other relative orientations of the axis of rotation and the prism axis. This also reduces the risk of personnel moving unnoticed at the location of the breathing equipment colliding with it.
[0019] The support can define at least one support surface, for example, by at least one support structure, such as, for example, a plurality of support protrusions, which are configured to contact the placement surface when the support is placed. Preferably, the at least one support structure defines at least one virtual support surface, which can be, for example, a support surface tangentially abutting against the at least one support structure. Thus, when the support is placed, the support surface of the respiratory device coincides with the placement surface of the device environment. Alternatively or additionally, the axis of rotation can be parallel to the support surface. Preferably, the support surface is a support plane. Preferably, the at least one support structure defines a plurality of virtual support surfaces, whose orientation and / or orientation relative to each other can be changed by rotation of the device housing about the axis of rotation, so as to provide the operator with multiple options for placing the respiratory device.
[0020] Preferably, the axis of rotation extends spaced apart from at least one output surface of the input / output device, such as a monitor, and particularly from the input / output device, such that the output surface and / or the input / output device can pass through relatively long bends when the entire device rotates about the axis of rotation. Thus, the input / output device can be largely displaced relative to the operator of the breathing device and simultaneously oriented at an angle by rotating the entire device within a support.
[0021] In principle, the axis of rotation can extend outside the device housing, resulting in a relatively large space for movement of the device housing along with the input / output devices. A compact space for movement, but still sufficient to orient the entire device according to its placement, can be achieved by having the axis of rotation extend through the device housing.
[0022] Breathing devices typically have multiple physical functional interfaces. These interfaces may include, for example, a breathing gas suction opening and / or an interface for establishing an electrical connection and / or an interface for establishing a hydromechanical connection and / or an interface for establishing a mechanical connection.
[0023] Preferably, the breathing device includes a fan as a pressure changing device as mentioned at the beginning, enabling the breathing device to draw in ambient air, which is also present as a breathing gas and is not restricted, through the breathing gas suction opening and deliver it to the patient.
[0024] The functional interface used to establish electrical connections can be used to power respiratory equipment or to connect to external peripheral devices, such as printers, modems, or data storage devices.
[0025] Alternatively, a functional interface for establishing a fluid-mechanical connection, either in conjunction with or other than a fan, can be used to connect to a respiratory gas reservoir or to a special gas reservoir, such as oxygen or nitrous oxide, which should be mixed into the respiratory gas. Such a connection structure, for example a quick-connect device for fluid mechanics, can be this functional interface. The functional interface for establishing a fluid-mechanical connection can also be used to connect a breathing hose, through which respiratory gas is delivered from the pressure-changing device within the device housing to the patient.
[0026] The functional interface for establishing a mechanical connection can be used to connect to a filter on the inhalation side, which has specialized filtration characteristics that exceed those of a breathing gas filter that is preferably interchangeably disposed in the device housing.
[0027] According to the present invention, a gas storage can be a gas storage contained in a container or a gas storage prepared for connection in a building or transport vehicle by means of the installation of pipelines and coupling structures.
[0028] Because tubing is connected to at least a portion of the functional interfaces on the device housing during operation of the breathing device, and the tubing extends away from the device housing, multiple functional interfaces are positioned on at least one main or even only section of the device housing along the axis of rotation by rotating the entire device about the axis of rotation to avoid unnecessary large-scale tubing movement.
[0029] In the case of a preferred prismatic housing, multiple functional interfaces are provided on at least one end face of the housing located on the axial end side with respect to the prismatic axis. For the aforementioned reasons, it is particularly preferred that all functional interfaces provided on the housing are located on a section of the housing pointing along the axis of rotation or the prismatic axis, especially on the end face of the housing on the axial end side.
[0030] In the preferred case where the fan is used as a pressure changing device, the functional interfaces are preferably distributed on the end faces of the two axial ends of the device housing, so that breathing gas is drawn into the device housing by the fan on the end face and can leave the device housing on the opposite axial end face for delivery toward the patient.
[0031] Preferably, the functional interfaces of multiple entities of the device housing, particularly all entities, are configured and arranged on the device housing such that they can be oriented in the axial direction about the axis of rotation and / or connected to mating interfaces via a connecting movement in the axial direction. Thus, by twisting the entire device about the axis of rotation, only the location of the functional interfaces and the trajectory for establishing connection with said functional interfaces are slightly altered. This simplifies the operation and use of the respiratory device in confined environments.
[0032] In a preferred embodiment of a device housing having a prismatic structure and a rotation axis parallel to or coaxial with the prismatic axis, the functional interfaces of the multiple entities of the device housing, particularly all the functional interfaces of the entities, are arranged on the end face of the axial end side of the device housing in the manner described above.
[0033] In principle, it is possible for the equipment housing to be directly and rotatably supported on the bracket, for example, by means of sliding support members, one of which is a sliding support structure on the bracket and the other is a sliding support mating structure on the equipment housing. However, it is advantageous for the equipment housing to be conventionally and releasably coupled to the bracket. "Conventionally and releasably" in this application means that the equipment housing can be coupled to the bracket without damage and then removed from the bracket with reasonable installation costs.
[0034] Preferably, the bracket thus has a first bracket section for holding the device housing and a second bracket section for holding the first bracket section, wherein the first bracket section is rotatably supported on the second bracket section about a rotation axis. Thus, the rotation support device can be configured separately and independently of the device housing and its construction between the first and second bracket sections. Therefore, the device housing, together with the input / output devices disposed thereon, can be without the functional components of a rotation support device.
[0035] According to a preferred improvement of the invention, the bracket, particularly the aforementioned second bracket section, has a locking device for locking the entire device in a rotatable position on the bracket. One device, consisting of the entire device and / or the first or second bracket section, movable relative to the locking device about a rotational axis, can have at least one notch, into which a protrusion of the corresponding other device can form-fit to establish a locking engagement, thereby securing the entire device, particularly the first and second bracket sections, in a relative rotatable position about the rotational axis. Preferably, the locking device is disposed on the bracket, and particularly preferably operably disposed on the second bracket section. Thus, the entire device, and (if present) the first bracket section, can rotate relative to the locking device about a rotational axis.
[0036] The locking engagement is released from the notch and protrusion by operating the locking device's mechanism, for example, by flipping at least one lever around the locking axis or by pressing the locking key. To avoid undesirable torsion of the entire device around the axis of rotation, the locking device is preferably pre-tightened toward the locking engagement, for example, by a spring mechanism. Instead of a form-fit engagement, the locking engagement can also be a friction fit. Thus, the entire device can be steplessly adjusted and stationary about the axis of rotation relative to the support, especially relative to the second support section. Since the entire device is reliably locked in the rotating position, a form-fit engagement is preferred as the locking engagement.
[0037] Preferably, the first and second support sections each form part of a support structure on which the breathing device can be placed on the ground. Preferably, the first support section has at least one, preferably at least two, support protrusions configured for support on the ground. Preferably, the second support section also has at least one, preferably two, support protrusions, such that the support protrusions of the first and second support sections together form at least one three-point support structure, based on which the breathing device can be reliably placed on the ground regardless of the corresponding rotational position of the entire device relative to the support. To avoid the typical rotation around the axis connecting two of the three support points for three-point mounting, the first and second support sections can together form a four-point support structure, wherein preferably two support points are formed by the first support section and the other two by the second support section, so that the breathing device can also be mounted on a flat ground regardless of the corresponding rotational position of the entire device.
[0038] The first support segment can have more than two support protrusions, such that, in the same relative position of the support segments, the breathing device can be placed on the ground either by means of a support structure formed by the support points of the first and second support segments, or by means of a support structure formed only by the support points of the first support segment. Similarly, it is also conceivable that the second support segment has more than two support protrusions. Thus, the breathing device can be placed on the ground by means of a support structure formed only by the support points of the second support segment.
[0039] In specific applications, a compact breathing device requiring minimal structural space may be more advantageous than a breathing device consisting entirely of a housing and input / output devices that are rotatable relative to a support around a rotation axis. In such cases, it is possible to propose that the first support section is conventionally and releasably accommodated on a second support section. Thus, either the housing can be used without a support, or without the first support section, or without the second support section.
[0040] To ensure that each of the two support sections can be individually connected to the equipment housing, it is advantageous that the first and second support sections each have a fixing structure configured to cooperate with a fixing structure provided or configured on the equipment housing for fixing to the respective support section. Thus, the equipment housing can be fixed only to the first support section, which is also rotatably connected to the second support section about a rotation axis relative to the support section. Alternatively, the equipment housing can be fixed only to the second support section, wherein the equipment housing is then immovable relative to the second support section. The second support section can then be used as a load-bearing support.
[0041] The device housing can be secured to one of the support sections originating from the first and second support sections via a clamping connection or a locking connection. For this purpose, a clamping structure can be provided on the first and / or second support section to clamp one section of the device housing. Alternatively, a locking structure can be provided that engages with a locking section of the device housing.
[0042] When each bracket segment is to be directly connected to the equipment housing, bolted connections are advantageous due to the need for both high connection security and a small structural space. For this purpose, each bracket segment can, for example, have a predetermined number of through holes, and the equipment housing can have threaded holes, which are flush with the through holes of the corresponding bracket segment in a predetermined fixed position on the equipment housing.
[0043] To simplify the carrying of the breathing equipment, it is theoretically possible to have a handle on the equipment housing. However, when the equipment housing is already designed for use with a support, it is more advantageous to design the equipment housing as compactly as possible and to incorporate a handle for hand gripping on the support.
[0044] For operating a breathing instrument, and especially for orienting the input / output devices around the axis of rotation, it is advantageous for the handle to extend parallel to the axis of rotation.
[0045] Especially for the safe transport of respiratory equipment in emergency medical transport vehicles, the respiratory equipment can have a suspension device configured to reliably and conventionally secure the respiratory equipment to an external structure. The term "transport vehicle" herein includes ground vehicles, particularly motor vehicles, aircraft, and water vehicles. Emergency medical transport vehicles typically have little to no surface space in the environment of the patient being transported, which would allow for the placement of the respiratory equipment. The patient transport space in such vehicles is usually maximized to accommodate onboard emergency medical equipment and storage space. However, with a suspension device, if the respiratory equipment cannot be placed due to ground conditions or a lack of sufficient space, a simple external structure within the transport vehicle or even at the point of use (e.g., at the accident site) is sufficient to secure the respiratory equipment to said structure. Therefore, the present invention also relates to respiratory equipment of the type mentioned at the beginning, having a suspension device for reliably securing at least one entire device, consisting of a housing and input / output devices, to an external structure. A respiratory equipment with a suspension device can have a support on which the housing is housed. Breathing devices with suspension devices are not necessarily required to be rotatably housed on a support about an axis of rotation, although this is preferred. The aforementioned improvements to the support, which do not involve the rotatability of the entire device about an axis of rotation, are also improvements to breathing devices with supports and suspension devices, wherein the entire device is non-rotatably housed on a support.
[0046] The suspension device can include a ring or eyelet. Thus, the external structure can include a hook or / and a protrusion. Preferably, the suspension device includes at least one hook or latch, such that a simple ring or eyelet or just a rod or beam is sufficient as an external structure for a suspended, fixed breathing device.
[0047] To enable the respiratory device to be suspended on as many different external structures as possible, the suspension device according to a preferred improvement of the invention is movable relative to the device housing and / or relative to the support. Thus, the suspension device, in particular the hook, can enter positions relative to the support that are advantageous for securing the respiratory device to the respective external structures. Preferably, the suspension structure is rotatable about a suspension axis. Preferably, this suspension axis is oriented parallel to the axis of rotation so that, after the respiratory device is suspended on the external structure, rotation of the entire device about the axis of rotation ensures the most advantageous and simple operability of the respiratory device in its subsequent positions.
[0048] Particularly preferably, the suspension device includes multiple hooks. Preferably, the suspension axis extends through a handle on the support, configured for hand gripping, wherein the handle itself is stably configured compared to a rod or rod segment. According to a particularly preferred embodiment for achieving a stable suspension of the breathing device without swaying tendency, hooks are respectively provided at two longitudinal ends of the handle. For easy and synchronous twisting of the multiple hooks, the handle preferably has at least two hooks, and particularly preferably a rotating shaft connecting the two hooks provided at the longitudinal ends of the handle.
[0049] The suspension device is preferably able to stop in different relative positions with respect to the support it supports, so as to lock the breathing instrument to the external structure in one position. Attached Figure Description

[0055] exist Figure 1 In this application, a preferred embodiment of the breathing device according to the invention is generally designated as 10 as an emergency breathing instrument. The emergency breathing instrument 10 includes a device housing 12 having a prism-like basic shape, currently having a square basic shape with rounded edges.
[0056] The device housing 12 extends along a virtual prism axis P, which is imaginary to pass through the device housing centrally along its longitudinal dimension. Around the prism axis P, a housing outer surface 14 extends radially spaced from the prism axis, housing a structural unit 16 having an input / output device 18. The input / output device 18 includes a monitor 20 for visually outputting data and information. Preferably, the monitor 20 is a touchscreen, allowing data and control commands to be input into the input / output device 18 via the monitor 20. A rotary switch 22 and a keyboard area 24 for inputting data and / or control commands are also shown on the input / output device 18. The switch is selected only by way of example. A frame 26 overlaps the edge of the housing outer surface 14 to seal the opening in the housing outer surface 14 through which the structural unit 16 of the input / output device 18 passes and is limited by the edge of the housing outer surface 14. Through the opening pierced by structural unit 16, input / output device 18 and control device 28 (see [reference]) are located inside device housing 12. Figure 4 They are connected by transmitting signals.
[0057] Figure 1 An observer also sees the end face 30 located on the right side, as viewed from the operator of input / output device 18. This end face has different surface areas for accommodating functional interfaces, which will be referred to below. Figure 3 A detailed explanation is provided. Figure 1 and 2 In this context, the functional interface becomes identifiable only through placeholders.
[0058] The outer casing 14 is formed by extruded or pressed pipe components 15, especially pipe components made of aluminum, for better heat conduction.
[0059] End face 30 includes a cover plate 32, which is preferably part of the functional device 34 (see [link]). Figure 4 The functional device includes a control device 28 and a fan 36 as a pressure changing device, and includes a breathing gas conduit 38. The control device 28 is connected to the fan 36 by transmitting signals, enabling the control device 28 to control the operation of the fan 36. Preferably, the functional device 34 is a pre-installed component, which is introduced as a whole into the conduit member 14 along the prism axis P. The functional device 34 may also include other functional units, which are not shown here but are only mentioned, such as a breathing gas filter, a power supply for converting external voltage into the instrument voltage of the breathing device 10, a housing well and / or a storage battery for the battery, a cooling body for drawing heat from the fan 36 to the outer casing 14, etc.
[0060] An elastomeric buffer 40 is provided around the area where the pipe member 15 and the cover plate 32 collide, serving as edge protection for the shell edges formed by the pipe member 15 and the cover plate 32. The elastomeric buffer 40 can be injection molded from a thermoplastic elastomer. The elastomeric buffer can be formed from silicone rubber, raw rubber, or rubber.
[0061] The breathing device 10 also includes a support 42, which includes a first support section 44 that is directly connected to the entire device 45, which consists of the device housing 12 and the input / output device 18, for example by screwing. Screwing, or generally the connection to the first support section 44, is preferably performed on the rear side of the device housing 12 opposite to the front side of the housing having the input / output device 18.
[0062] The bracket 42 also includes a second bracket section 46, on which the first bracket section 44 is rotatably guided about a rotation axis D. The first bracket section 44, together with the entire device 45 fixed thereto, can rotate about the rotation axis D over an angular range of at least 40°, preferably at least 50°. In this example, the rotation axis D coincides collinearly with the prism axis P. Preferably, the rotation axis D does not penetrate the bracket 42.
[0063] The first support segment 44 has two arms 44a and 44b that are curved in a fan shape at least along their guide region. These arms surround the segment of the device housing 12 in a circumferential direction around the prism axis P, and each arm has a fan-shaped profile structure 48a or 48b within the guide 50 (see [link]). Figure 3 Along the fan-shaped configuration of arms 44a and 44b, along a fan-shaped track around the rotation axis D, with the rotation axis D as the midpoint axis of the fan-shaped track, it can be translated and moved. The profile structures 48a and 48b can be T-shaped profiles, L-shaped profiles, or double T-shaped profiles, to name a few.
[0064] The second support section 46 has two parallel arms 46a and 46b, and a handle 52 connecting the arms 46a and 46b is provided on the longitudinal end of the arms away from the equipment housing 12. (See the following text for further details.) Figure 4 As described in a preferred improvement of the breathing device 10, the handle 52 is rotatably disposed relative to the arms 46a and 46b about the suspension axis A. The suspension axis A is preferably parallel to the rotation axis D. The handle 52, when rotatably supported about the rotation axis A, is preferably cylindrical, such that its exterior is as constant as possible or completely constant with respect to rotation about the suspension axis A.
[0065] Arms 46a and 46b are configured to bend around a curved axis parallel to the axis of rotation D or the prism axis P. More specifically, it is preferable that arms 46a and 46b partially encircle the entire device 45 along the circumferential direction around the axis of rotation D, independent of the rotational position of the entire device 45. The total mass of the breathing device 10 is balanced here, or the handle 52 is positioned such that when the breathing device 10 is freely suspended on the handle 52 by means of a suspension axis A orthogonal to the direction of gravity, the connecting plane including the suspension axis A and the prism axis P is inclined relative to the housing 42 at a value of no more than 10°, preferably no more than 7°, with respect to the direction of gravity and the corresponding rotational position of the entire device 45.
[0066] exist Figure 2 Re-shown in Figure 1 The breathing device 10, wherein the entire device 45 rotates clockwise around the axis of rotation D to another position.
[0067] When the breathing device 10 is set at a relatively high height, such as above the head height of the person operating the breathing device 10, it is possible to select... Figure 1 The entire device 45 is positioned within the support 42. The entire device 45 can then be oriented such that the operating area of the input / output device 18, along with the monitor 20, switch 22, and button 24, points downwards away from the handle 52. In contrast, when the breathing device 10 is positioned relatively low, for example, on the ground where the person operating the breathing device 10 stands, it is possible to select... Figure 2 The entire device 45 is positioned within the bracket 42. Thus, the entire device 45 can be oriented such that the operating area of the input / output device 18 points upward toward the handle 52.
[0068] The bracket 42, particularly the second bracket section 46 in the preceding embodiments, has a locking device 53 for locking the entire device 45 in a rotatable position. In the locking device 53, in... Figures 1 to 3The diagram shows two levers 53a and 53b that are reversible about a locking axis preferably parallel to the rotation axis D and / or parallel to the device axis A. Alternatively or additionally, levers 53a and 53b can be translationally movable. One of the devices, particularly the fan-shaped profile structure 48a or 48b, from the locking device 53 and the first support section 44, can have at least one notch into which the protrusion of the corresponding other device can form-fit, so as to fix the first support section 44 and the second support section 46 in a relative rotational position about the rotation axis D. The locking engagement is released by flipping levers 53a and / or 53b about the locking axis. To prevent undesirable rotation of the entire device 45 about the rotation axis D relative to the second support section 46, the locking device 53 is pre-tightened toward the locking engagement. Instead of a form-fit engagement, the locking engagement can also be a friction fit engagement. Thus, the entire device 45 can be steplessly adjusted and stationary about the rotation axis D relative to the second support section 46. Due to the more reliable locking of the entire device 45 in the rotational position, the form-fit engagement is preferred as a locking engagement.
[0069] As in Figure 3 The most clearly identifiable, yet also Figure 2 As can be identified, the support 2 has a support structure 54, which in the illustrated example has four support protrusions 56a, b, c, and d. Of these, support protrusions 56a and 56b are formed on the arm 44a of the first support segment 44, and support protrusions 56c and 56d are formed on the parallel arm 44b of the first support segment 44. Furthermore, the support structure 54 has a support protrusion 58a formed on the arm 46a of the second support segment 46 and a support protrusion 58b formed on the arm 46b of the second support segment 46. Support protrusions 58a and 58b can also be replaced by a single support protrusion extending along the axis of rotation D over the entire length of the second support segment 46.
[0070] The support protrusions 56a, b, c, and d of the first support section 44, protruding from the lower side of the device housing 12, do not change their relative positions to each other. Similarly, the support protrusions 58a and 58b of the second support section 46 do not change their relative positions to each other. However, rotation of the entire device 45 about the rotation axis D changes the relative positions of the support protrusions 56a, b, c, and d of the first support section 44 with respect to the support protrusions 58a and 58b of the second support section 46.
[0071] exist Figure 3It is clearly identifiable that, depending on the rotational position of the entire device 45 and thus the first support section 44 relative to the second support section 46, the breathing device 10 can be placed on a support surface defined only by the support protrusions 56a, b, c, and d of the first support section 44, or on a support surface defined only by the support protrusions 56b and 56d of the first support section 44 and the support protrusions 58a and 58b of the second support section 46, or on a support surface defined only by the support protrusions 56a and 56c of the first support section 44 and the support protrusions 58a and 58b of the second support section 46.
[0072] Figure 3 An example is shown with a breathing gas outlet 60 as a functional interface through which inhaled breathing gas, delivered by the fan 36 of the pressure-changing device, is discharged from the device housing 12 toward the patient connected to the emergency breathing apparatus 10. The breathing gas outlet 60 forms the end of the breathing gas line 38 of the functional device 34. A supply device or special gas reserve can be connected to the special gas coupling section 62 to supply a gas different from the air drawn in by the fan as breathing gas, either as inhaled breathing gas or as part thereof, into the breathing gas line 38.
[0073] Figure 3 Connecting sleeves 64a and 64b are shown as additional functional interfaces to which pressure sensing hoses can be connected. The pressure sensing hoses, at their ends furthest from connecting sleeves 64a or 64b, are respectively connected to the internal regions of a differential pressure flow sensor to measure proximal inhaled gas flow and, preferably, also exhaled respiratory gas flow. These two internal regions of the differential pressure flow sensor are separated from each other in a manner known per se by the variable flow resistance due to the respiratory gas flow.
[0074] Via grid input 66, the emergency breathing device 10 can operate using energy from an external power network, such as from the public power grid or the vehicle's onboard power grid, provided the space for the grid interface is available. All electrical functional units of the emergency breathing device 10 can then be supplied with grid energy, wherein the grid voltage is converted to a low-volt DC voltage via a power supply unit that is a pre-installed functional unit 34. Similarly, a battery (not shown) can be charged. A socket 68, serving as another functional interface in the housing 12, is provided for connecting external sensors, particularly a CO2 sensor. This CO2 sensor can, for example, be installed on a flow sensor coupled to the emergency breathing device 10 and coupled as a sensor device.
[0075] By arranging the functional interfaces within the cover 32, the travel distance of each functional interface is short when the entire device 45 is rotated about the axis of rotation D. Furthermore, all functional interfaces can be connected to their respective associated conduits via axial movement about the axis of rotation D through mating interfaces (e.g., plugs or sockets) to which they are to be connected. Thus, rotation of the device housing 12 about the axis of rotation D does not alter, or only slightly alters, the orientation of the conduits spatially configured to establish connections with the functional interfaces in the cover 32.
[0076] Furthermore, the conduits connected to the functional interfaces exit the respective functional interfaces parallel to the rotation axis D, ensuring that possible rotations of the equipment housing 12 around the rotation axis D of 40° to 50° do not cause undesirable conduit entanglement, such as that that might occur when the conduits exit the housing outer cover 14 in a directional manner. This also approximately eliminates the possibility of collisions between the connected conduits and the support 42.
[0077] exist Figure 4 Roughly illustrated in three dimensions Figures 1 to 3 The breathing device 10 is an advantageously improved type. Figure 4 An observer also sees another end face 69 of the device housing 12 opposite to end face 30, which is formed by a cover 70 that can be locked and unlocked by a rotation protection device 72 on the pipe member 15. In the unlocked state, the cover 70 can be removed from the pipe member 15 along the rotation axis D.
[0078] The cover 70 has a breathing gas suction opening 74 centrally traversed by the prism axis P and the rotation axis D. A fan 36 draws ambient air through this opening as breathing gas. Preferably, the drawn-in ambient air is drawn in and cleaned by a filter (not shown) located downstream of the breathing gas suction opening 74. The inner surface of the breathing gas suction opening 74 has an internal thread 76, on which a mechanical object, such as an additional high-powered filter, can be releasably coupled to the breathing device 10. The breathing gas suction opening 74 and the internal thread 76 form additional functional interfaces of the breathing device. Furthermore, these functional interfaces point in a direction parallel to the rotation axis D. The turning axis of the internal thread 76 is collinear with the central axis of the breathing gas suction opening 74 and with the rotation axis D.
[0079] Respiratory equipment 10 Figure 4 It has a suspension device 78, and the bracket 42 together with the entire device 45 housed therein can be housed on an external structure 79, such as a rod, by means of the suspension device.
[0080] The suspension device 78, in the example shown, has two hooks 78a and 78b. A gripper 52, in the current example, is positioned between these two hooks 78a and 78b and is rigidly connected to the hooks 78a and 78b for common rotational movement about the suspension axis A. Therefore, the gripper 52 and the hooks 78a and 78b are rotatable about the suspension axis A relative to the arms 46a and 46b of the second support section 46.
[0081] Each hook 78a and 78b is in Figure 4 The middle part is shown in three different positions. The position shared by hooks 78a and 78b is indicated by an apostrophe and a double apostrophe.
[0082] The release button 80 is used to release the stop of the suspension device 78 together with the gripper 52 on the arms 46a and 46b of the second bracket 46. For example, when the stop device that causes the stop is engaged by form-fitting engagement, the stop can be a graded stop with a predetermined scale. When the stop device is engaged by friction, the stop device can be steplessly engaged. When the release button is not pressed and there is no load, the stop device of the structural unit consisting of the suspension device 78 and the gripper 52, which can move together, is preloaded by at least one spring device to the stop position that stops the structural unit. By the axially centered arrangement of the release button 80, which is radially operable relative to the gripper 52 about the device axis A, the hooks 78a and 78b can be twisted about the device axis A by one hand, not only by the left hand but also by the right hand.
[0083] Alternative to Figure 4 As shown in the diagram, the two hooks 78a and 78b are capable of rotating together, however, independently of the gripper 52, about the suspension axis A. Alternatively, each of the hooks 78a and 78b is capable of rotating individually, independently of the other components of the breathing device 10, about the suspension axis A.
[0084] Hooks 78a and 78b are preferably shaped such that there are operating positions for hooks 78a and 78b, in which sections extend from the rotational joints of hooks 78a and 78b toward the corresponding hook tips, and preferably also include curved sections to which the hook tips are connected, extending parallel to the following sections of arms 46a or 46b, which also extend from suspension axis A. The operating positions are in... Figure 4 The middle position is the initial position of hooks 78a and 78b, indicated by "78a" or "78b".
[0085] The position indicated by 78a' or 78b' can be an intermediate position in which the breathing device 10 suspended on the external structure 79 bears a supporting moment by gravity toward the wall close to the external structure 79 but on the other side of the breathing device 10. In this case, the breathing device 10, supported toward the wall located behind the external structure 79, occupies a stable position solely due to its own weight, in which the breathing device can be operated and manipulated.
[0086] The position indicated by 78a or 78b can be a terminal position, in which the breathing device 10, suspended from the external structure 79, can be suspended freely by gravity, for example, when there is no wall near the external structure 79 to support the breathing device 10. The breathing device 10 can operate even when suspended in the terminal position.
[0087] Hooks 78a and 78b can be preloaded into their initial positions by a spring mechanism. The spring mechanism can be located in the second support section 46, for example, in one of the sleeve sections between hook 78a or 78b and the gripper 52. These three positions can be the only locking positions for hooks 78a and 78b, or other locking positions for hooks 78a and 78b can be provided around the device axis A.
[0088] exist Figure 4 The suspension device 78 shown can also be mounted on the bracket 42, and especially on the second bracket section 46, without the torsion of the entire device 45 about the rotation axis D, and especially without the relative torsion of the entire device 45 relative to the second bracket section 46.
