Description

Stent system and connector for medical devices

Technical Field

The present application relates to a stent system for medical devices and components thereof to enable mobility of medical devices.

Background

Hospital patients often use respiratory equipment for respiratory therapy, such as "high flow" therapy equipment. Typically, once the initial procedure/treatment is completed, the patient undergoing respiratory therapy needs to be transferred to other rooms in the hospital for recovery. If the breathing apparatus does not have a battery, movement means that the patient being treated for breathing that is to be transferred will need some scheduling of the power supply of the breathing apparatus.

This situation can also occur with other medical devices.

Detailed Description

1. To summarize:

referring to fig. 1, a mobile rack system ("rack system") 10 for carrying a breathing apparatus 11 and a power supply 12 according to embodiments herein is depicted. The term "carrying" encompasses the support and/or movement of the breathing apparatus 11 and the power source 12. Embodiments may relate to a stent system 10 as a whole, including

stents

13A, 13B and stent links 20; the bracket coupling 20 itself may also be involved. This facilitates patient mobility when using the breathing apparatus.

The support system is described herein in connection with a breathing apparatus. The breathing apparatus may provide respiratory therapy, which may be, without limitation, one or more of the following:

high flow therapy devices capable of providing high flow therapy, such as non-invasive nasal high flow therapy devices, may provide nasal high flow therapy (NHF), or tracheal high flow therapy, or other non-invasive ventilation (NIV).

A Positive Airway Pressure (PAP) device that provides positive airway pressure, such as a CPAP (continuous positive airway pressure), bi-level PAP device, or other PAP device.

Any such breathing apparatus may also provide humidification of the gases provided to the patient. Humidity helps to improve the treatment, preferably for high flow treatments. Humidity improves treatment comfort and thus compliance. Humidity also helps maintain airway function.

By way of non-limiting example, the breathing apparatus may provide humidification at a minimum of 44mg/L humidity and/or 37 ℃ dew point.

The mounting system allows mobility of the breathing apparatus which requires high power requirements, especially when equipped with humidification. In general, the embodiments described herein make it easier for a patient to move and maintain continuity of treatment for the patient while using the breathing apparatus.

2. Exemplary embodiments:

one embodiment of the stent system will now be described.

2.1, mobile modular support system:

the rack system 10 includes a first (mobile breathing apparatus) rack 13A for supporting breathing apparatus 11, a second (mobile auxiliary) rack 13B for supporting a power source 12 (e.g., an uninterruptible power supply "UPS") and/or an auxiliary gas source 14, and a rack coupling 20, the rack coupling 20 coupling the first rack 13A and the second rack 13B together so that they may be moved as a single system/unit 10. Together, this forms a mobile module support system. By doing so, this allows one or more of the following: a) Supporting and moving the breathing apparatus 11 as the patient moves; so that b) the breathing apparatus can be carried as needed as the patient moves, while still remaining connected to the power supply 12 and remaining operational and/or therapeutic during the transfer; while c) reducing interference with the patient and/or reducing the difficulty of medical personnel moving the patient and the breathing apparatus 11. In addition or as an alternative, the modularity enables the power accessory rack with the power source to be interchanged and connected with any breathing apparatus/breathing apparatus rack. In this case, the breathing apparatus does not require its own power source, such as a battery. This makes the design of the breathing apparatus simpler.

In general, the embodiments described herein make it easier for a patient to move while using a breathing apparatus and maintain continuity of treatment to the patient.

The support system 10 is a modular system in which the respiratory apparatus support 13A, auxiliary support 13B, and support coupler 20 components can be selected and assembled together as desired, and each component can be manufactured and sold separately and/or together. Typically, in a hospital environment, there will be a number of

racks

13A, 13B and rack couplers 20, all of which may be interconnected in a modular "mixed-fit" fashion as desired.

2.2, breathing equipment support and auxiliary support:

the breathing apparatus support 13A and the auxiliary support 13B may be any suitable device capable of mounting and holding breathing apparatus, such as any device known to those skilled in the art.

Each stand (collectively 13, denoted 13A or 13B, unless a specific stand is referred to; hereinafter the same reference numerals will be used for both stands 13) includes a base 15, the base 15 carrying wheels (e.g. castors) 16 or other means for mobility. As shown, in this case, the base 15 comprises a four-point cross-type lower chassis, with two cross-members 17, at the end of each of which is attached in a suitable manner a caster 16, the caster 16 being rotatable about a connecting pivot 18 connected to the respective cross-member. The cross bar may be formed with a central depression 19 to reduce the overall height of the stand for ease of handling and stability by the medical staff whilst still providing sufficient height for the ends of the castors of the required size/height above the ground.

The bracket 13 also includes a support, optionally in the form of a post member (also referred to as a "post") 9, in the form of a post made of any suitable metal, plastic, or the like. At the top end, the stand comprises hooks or other attachments 8 for mounting iv bags or other medical supplies and a handle 7 (e.g. in the form of a handle) for moving the stand.

Breathing apparatus rack 13A includes an attachment for basket 6 or other container for holding medical supplies, documents, or other items and another attachment for breathing apparatus 11.

Accessory bracket 13B includes an attachment for basket 6 or other container for holding medical supplies, documents, or other items. It also includes an attachment for an auxiliary gas source 14, such as an oxygen tank. It also includes a mounting for the power supply 12, which may also be seated in a recess 19 formed by the base beam.

Each stud member may have other brackets, shelves or other fittings.

Each post member 9 may optionally have a receiver for a coupler locator, as described below.

The breathing apparatus support 13A and the auxiliary support 13B may be the same or have different configurations. The two brackets described above with reference to fig. 1 are merely examples and should not be considered limiting. More generally, a stand having a post may be used with a lower chassis to which a plurality of wheels are coupled to provide mobility, wherein the stand may include a bracket, shelf, or the like that is removably coupled to the post and/or other portions of the stand. Any device that has a base for transport and provides mounting for a breathing apparatus and/or a power supply may be used. For example, the stent of PCT/IB2020/056933 (WO 2021/014392) is another example that may be used, and is also incorporated herein by reference in its entirety.

2.3, bracket connector:

fig. 2 shows an overview of the bracket coupling 20, the coupling 20 comprising a coupling arm 21 with

post member couplings

22A, 22B (which may be the same or different, as described later, and may be collectively referred to as 22) at both ends of the coupling arm 21. The bracket coupling 20 may be (mechanically) connected at each end to the post member 9 of each of the breathing apparatus brackets 13A and the auxiliary bracket 13B (see fig. 1) to connect the two brackets together in an integral manner so that they can move together. The bracket coupler 20, once connected to the post member of each bracket, forms a bracket system.

The bracket coupling will now be described in more detail with reference to fig. 2 to 3H.

Referring first to fig. 2, the linkage arm 21 comprises an elongated/longitudinal member, such as a rod made of metal or plastic, preferably of elongated cylindrical nature, but other cross-sectional profiles (e.g., square, hexagonal, octagonal, or other polygonal profiles) are also possible. The attachment arm is of a suitable length to provide the required distance between the two brackets 13 when the two brackets 13 are connected together by the bracket attachment 20. By way of non-limiting example, the length of the arm may be in the range of about 30cm to about 2m to provide a suitable spacing between the two supports so that the wheels do not interfere with each other, while still providing a low profile to pass through hospital corridors without being cumbersome. In the case of the latter-mentioned telescopic embodiment, one or more of the extended, partially extended or even unextended configurations may vary from about 30cm to about 2 m.

A support coupling provides an electrical coupling between the breathing apparatus support and the auxiliary apparatus support to provide an electrical coupling between the power source and the breathing apparatus. In the fig. 2 embodiment, in one option, the link arm has a longitudinal channel 23 (e.g. as being hollow, or having some other longitudinal space-see dashed lines) and two

openings

24A, 24B, each opening towards one end of the link arm 21 to accommodate a power cable 25. The power cable extends through the longitudinal channel 23 and out of each

opening

24A, 24B and has a

power coupling

26A, 26B (preferably, but not necessarily, female) at each end. The power coupling 26A at one end is for connecting a power cable of the breathing apparatus 11 on the breathing apparatus support 13A, and the power coupling 26B at the other end is configured for plugging into a socket of the power source 12 on the auxiliary support 13B. This enables the breathing apparatus 11 on the first leg 13A to be coupled with the power source 12 on the second leg 13B to provide power to operate the breathing apparatus 11.

The power cable 25 is retrofittable so that the power cable 25 can pass through the longitudinal channel 23 via an opening (in this case, the opening is large enough to allow at least one

power coupling

26A, 26B to pass through); or the power cable 25 is made in the link arm 21 (in which case the

openings

24A, 24B may be smaller than the

power links

26A, 26B to prevent them from passing through, thereby preventing the power cable 25 from being removed from the link arm 21). Other types of electrical couplings may be used and any suitable alternative may be selected by those skilled in the art. For example, another option for the power coupling 27 is shown in FIG. 2A.

The power couplings are configured to be coupled to respective power output couplings of a power source. In one option, as shown in fig. 2B, a non-limiting example of a power output coupling 28A for the power source 12 is provided that may be used with a power coupling on the coupling arm 21. The mains power output coupling 28A comprises a power cable 29A with a mains or similar type of power socket 29B (e.g. a three-pin socket) for coupling to a power coupling on the coupling arm 21. The power output coupling 28A may be hardwired to the power source 12 via a power cable 29A. Alternatively, it may be removably coupled to the power source 12 by a power coupling 29C (e.g., a three pin connector as shown in fig. 2B) at the other end of the power cable that is compatible with the power source, the power coupling 29C being connected to a corresponding coupling on the power source 12. Such a connector may remain connected to the power source 12 to allow the medical device 11 to be easily plugged into the power source 12, much like a standard wall outlet.

In this configuration, the power coupling 28B on the coupling arm 21 will have a complementary, e.g., three-pin plug 29B' that couples to a three-pin receptacle 29B on the power output coupling 28A on the power source 12. Fig. 2C shows such a possible three pin plug 29B' that may be used in place of the receptacle 26B shown in fig. 2 or 2A. For example, the power cable 25 passing through the shaft of the coupling arm 21 may be connected at one end to the medical device 11 and at the other end (using the power coupling 28B/29B' in fig. 2C) to the three-pin socket 29B of the plug connector 28A shown in fig. 2B.

It should be noted that the three pin receptacle 28A and plug 28B shown in the figures are standard in new zealand. Those skilled in the art will appreciate that the multi-pin plug/jack standard is different in different countries and may be different than that shown. A standard plug/socket of a particular country may be used or the plug/socket may be a universal connector.

The bracket coupling 20 may be connected to the post member 9 of each bracket 13 by

post couplings

22A, 22B provided at each end of the coupling arm 21. The post coupling members may take any suitable form and may be the same, similar or different, depending on the embodiment to be elucidated. By way of example, referring to, for example, fig. 3A-3H, each

column coupling

22A, 22B (shown generally at 22) may take the form of an articulated clamp. Each comprising first and second clamp halves 30A, 30B. The first clamp member 30A generally takes the form of a semi-cylinder (ring) having a protruding hinge portion 31A on one edge 33A. The second clamp member 30B also generally takes the form of a semi-cylinder (ring), with a complementary notch hinge portion 32B on one edge 34B, which notch hinge portion 32B engages and is pivotally attached to the complementary projecting hinge portion 31A on the first clamp member 30A. The notch 32B is defined by two notch projections on the edge 34B. As shown, the first and second clamp members are hinged at hinge/pivot 37, the hinge/pivot 37 being formed by a pin 37A, the pin 37A passing through a hole extending through a notched tab on the second clamp 32B and a protruding hinge tab 31A on the first clamp half 30A. The first and second clamp halves may be pivotally/hingedly movable from an open configuration in which the clamp may be placed around a post member of the stand to a closed configuration in which the coupling member may clamp onto and couple to the post member. This forms a pivotable clamp.

Each of the first and second clamp halves 30A, 30B has complementary closure means to close and hold (e.g. lock) the two clamp halves in a closed configuration when placed and clamped around the post member 9 of the bracket 13. Examples of closure devices will be described in further detail later, but the closure devices may take the form of screws, clamps, latches, pins, or other suitable closure devices 38. To attach the bracket coupling 20 to the first and second brackets 13, each post coupling 22 is opened by manipulating the closure device 38, hingedly moved about the hinge portion 37, placed around the post member, and then clamped to the post member 9 by hingedly moving the half clamp members 22 at the hinge portion 37. The closure device 38 is then operated to lock the post coupler 22 to the post member 9.

In one example, the closure device 38 is in the form of a screw member that passes through a threaded hole 38C that extends through the first clamp half 30B to the second clamp half 30A. By tightening the screw members, the two

clamp halves

30A, 30B are brought together and can be clamped and held against the post member 9 of the bracket. The screw may take any suitable form. For example, as shown in fig. 3A, 3D, and 3H, the screw may take the form of a screw 38A, and the screw 38A may be manipulated (loosened and tightened) by a person without the use of tools via a screw handle at the head. In another option, a tool adjustable screw 38B may be used, such as a screw with a socket head, requiring a socket wrench (or other suitable device) to loosen and tighten (see fig. 3B, 3C, 3E, 3F, 3G).

In one possible option, it is desirable that the bracket coupling 20 be permanently or semi-permanently attached to one of the brackets 13. In this way, the bracket coupling 20 is always available and will not be lost and unnecessarily searched. In this case, the bracket coupler 20 may have a human adjustable screw 38A at one end and a tool adjustable screw 38B at the other end. The bracket 13 with the attachment arm 21 permanently or semi-permanently attached is attached by a post coupling 22 with a tool adjustable screw 38B. This means that the coupling 22 is not easily or inadvertently removed, but requires a tool to work in tandem to remove it. This means that the bracket coupling 20 is less likely to be unnecessarily detached from the bracket 9. At the other end, the post coupler 22 uses a user adjustable screw 38A so that it can be easily attached to and detached from the post member 9 of the bracket. In one embodiment, it is preferable to form semi-permanent/permanent attachments on the cradle 13B with the power source 12, as there are fewer of these attachments around. But this is not a necessary requirement. It should be noted that other closure devices 38 are contemplated, including permanent, semi-permanent tool-operated and/or human-operated.

Each

clamp half member

30A, 30B may be configured to be permanently, semi-permanently, or removably attached to the attachment arm 21. Alternatively, each clamp half member may be integrally formed with one end of the linkage arm 21 in a suitable manner. As shown in fig. 3G and 3H, the coupling arm 21 (which is cylindrical) may be attached by a screw 35, the screw 35 passing through a hole 36 in the second clamp member 30A, the hole 36 passing through a corresponding hole in the rod.

The stent coupling 20 may also include a gas conduit that extends externally along the coupling arm or in a channel.

2.4, a using method:

a method of assembling the rack system so as to be able to carry the breathing apparatus and to be able to give mobility to the overall patient will now be described with reference to fig. 4. It should be understood that the steps herein do not have to be performed in the particular order presented. The order may be changed.

The patient is using the breathing apparatus 11 carried on the breathing apparatus support 13A. When a patient wants to move, they need to carry with them a breathing apparatus. However, the breathing apparatus may be plugged into a wall socket, for example, to provide power. Therefore, if they want to carry the breathing apparatus with them, another solution must be found because they cannot move the breathing apparatus while plugging it into a wall socket.

First, the patient or medical personnel (collectively "the user") collects the modular components, namely the breathing apparatus support 13A, the auxiliary support 13B, and the support coupling 20. These may be in different places. For example, a plurality of auxiliary racks 13A with power sources 12 and/or oxygen sources 14 are distributed throughout the hospital, possibly connected to wall outlets, to charge the power sources 12 on the racks 13B. Once the components are collected, they may be assembled into the stent system 10. Referring to step 40 of fig. 4, the patient or medical personnel (user) attaches (detachably couples) the rack coupling 20 to the post members 9 of the breathing apparatus rack 13A and the auxiliary power rack 13B in any suitable order. The user does this by operating each respective post coupling 22 in the required manner to attach it to the respective upright member 9. This will vary depending on the type of embodiment of the post coupling 22.

For the above-described column coupling 22 embodiment, to attach the bracket coupling 20 to the first and

second brackets

13A, 13B, each column coupling 22 is opened and placed about each column member 9 by manipulating the closure device 38 and hingedly moving the coupling 22 about the hinge portion 37, and then clamped thereto by hingedly moving each half clamp member 22 at the hinge portion 37. The closure device 38 is then manipulated to lock the post coupling 22/clamp halves 30A, 30B to the post member 9. Once the rack coupler 20 is installed, the modular components are assembled into the rack system 10, and the rack system 10 is mobile and ready for removal.

Referring to step 41, once the two brackets 13 are coupled by the bracket coupling 20, the breathing apparatus 11 is de-energized; and if the breathing apparatus needs to be connected to an oxygen source, in the case where the breathing apparatus is connected to a fixed oxygen source in a hospital wall or the like, the oxygen source is switched from the wall source to the oxygen source 14 carried on the auxiliary support 13B. The breathing apparatus 11 is connected to a support link power cable 25, the support link power cable 25 also being connected to the power source 12 on the auxiliary support 13B. The breathing apparatus 11 is then switched on again. This results in the rack system arrangement 10 of fig. 1.

Referring to step 42, at this point, the patient (who is receiving therapy from the breathing apparatus) may move anywhere they are going with the support system 10, including the breathing apparatus 11, power source 12 and oxygen source 14 on both supports coupled to the support coupling.

Referring to step 43, once the patient reaches the destination, the gantry system 10 can optionally be disassembled. Although this is not required, it may be preferred so that the auxiliary stent 13B can be released and used for other patients in a similar manner. To disassemble the rack system 10, the breathing apparatus 11 is shut down and disconnected from the rack coupling power cable 25. The oxygen source is switched from the oxygen source 14 on the accessory bracket to, for example, a stationary oxygen source (e.g., on a wall). The breathing apparatus 11 may then be switched on. The power source 12 on the auxiliary stand 13B may also be plugged into a wall outlet to recharge its power source 12.

Referring to step 44, the bracket coupler 20 may then be detached from the post member 9 of the respiratory bracket 13A and the auxiliary bracket 13B. This may occur in any suitable manner depending on the nature of the post coupling but, for example, with reference to the coupling 22 described above, the closure device 38 may be opened and the clamp halves 30A, 30B hingedly moved and opened and removed from the post member 9 of each

bracket

13A, 13B as required.

There are many variations of this assembly and disassembly method.

As previously mentioned, in one possible embodiment, the bracket coupling 20 may be permanently, semi-permanently, or integrally attached to one of the bracket post members 9 (most likely, but not limited to, the post member of the power auxiliary bracket 13B). The user does not have to search for the stand coupling 20, which is instead already coupled to the auxiliary stand.

3. Alternative embodiments:

some alternatives of the bracket coupling, power cable and post coupling will be described below. These are just some variations and others are possible. It should be understood that these may be mixed and matched with any of the embodiments described above, and that any of these may be used in the same way as described above.

Additionally or alternatively, the stand coupling may include a coupling arm that is electrically conductive with an integral or removably attachable electrical connector to electrically couple the breathing apparatus and the power source, either in place of or in addition to the cable. The breathing apparatus and the power source and/or each of the brackets may be coupled to a respective electrical connector on the bracket coupling. This helps to simplify the connection of the breathing apparatus to the power supply, due to the electrical connector.

Additionally or alternatively to any of the above, the support coupling may include an integral conductor (e.g., hard-wired) to electrically couple the breathing apparatus with the power source, instead of or in addition to the cable. For example, the bracket coupling may have an integral wire formed in the coupling arm with integral or removably attached electrical connectors at both ends of the coupling arm. The breathing apparatus and the power source and/or the respective support may be coupled to the respective electrical connector. This helps to simplify the connection of the breathing apparatus to the power supply, because the electrical connector in the arm and the integral conductor are coupled.

The closure device 38 may also be used to clamp the

clamp members

30A, 30B, thereby allowing the clamp members to be attached around column members 9 of different diameters. Either or both clamp members of the linkage arm may have a closure device 38 or a plurality of closure devices.

Referring to fig. 5, rather than the power cable 25 passing through the longitudinal passage 23 in the coupling arm 21, the power cable 25 is disposed outside of the coupling arm 21 and attached to the coupling arm 21 by a suitable fastener 50, such as by a cable tie, clip, or strap. It may also be helically wound. This provides a retrofittable option. Likewise, any suitable power cable may be used. Any suitable number of cable attachments may be used. Alternatively or additionally, the power cable may be helically wound around the attachment arm.

Referring to fig. 6, the attachment arm may be attached to the post coupler in different ways. One of the clamp members (e.g., 30A) has an opening 60 sized and shaped/contoured to fit the corresponding end shape/contour 61 of the cross-section of the linkage arm 21. The respective ends of the attachment arms 21 are tapered to allow a friction fit into the openings 60. It should be understood that the shape/profile of the opening 60 and the attachment arm end shape 61 may be other forms, such as circular, square, triangular, hexagonal, octagonal, or any other polygonal or other shape. Furthermore, the shape of the end portion need not be the same as the cross-sectional shape of the main portion of the attachment arm 21-the cross-sectional shape 61 of the attachment arm end portion may be shaped differently. Furthermore, the opening 60 in the clamp member half need not pass completely through the clamp member-it may pass partially or completely through. In addition, there may be other attachment means than a friction fit, and FIG. 4 is only one example.

Referring to fig. 7A to 7D, the link arm 21' is telescopic so that the length of the link arm can be varied. It comprises a first portion 21A and a second portion 21B, wherein the second portion slides within the first portion. The screw coupling 71 can be used to release and adjust the extension of the telescopic coupling arm. For example, the threaded coupling may take the form of an attachment portion 72A and a threaded portion 72B that may be connected together to secure the first and

second portions

21A, 21B of the coupling arm 21. This enables the distance between the breathing apparatus support 13A and the auxiliary support 13B to be adjusted before or after coupling. The telescopic feature may further enable more efficient storage by allowing the linkage arm to occupy less space in the retracted state if the linkage is to remain attached to the stand during storage. The telescoping linkage arm helps the user to change the spacing between the breathing apparatus support and the accessory support. This facilitates handling of the rack system throughout the hospital, for example in corners, in narrow corridors, or in elevators. This also helps to space the carriages apart so that the two chassis or wheels of each carriage do not interfere with each other. Further changing the spacing allows the user to walk between the two stands, making it easier to control the coupled system from place to place. In addition, the addition of the handle 70 in FIG. 7D facilitates maneuvering of the system.

The post coupler 22 may take any suitable form. Another example is shown in fig. 8. Each post coupling may take the form of an articulated

clamp

30A, 30B, as previously described, but with variations. They comprise first and second

clamp half members

30A, 30B. The first clamp member 30A is generally in the form of a semi-cylinder having a protruding hinge portion 31A on one side edge 33A and a notched hinge portion 32A on the other side edge 34A. The notch is formed by two notch projections on edge 34A. The second clamp member 30B also takes the form of a generally semi-cylinder having on one edge 33B a complementary projecting hinge portion 31B configured to engage a complementary notch hinge portion 32A on the first clamp member 30A, and on the other edge 34B a notch hinge portion 32B which engages and is pivotally attached to the complementary projecting hinge portion 31A on the first clamp member 30A. The notch is formed by two notch projections on the edge 34B. The second clamp member 30B also has a secondary coupling 39 for positioning the coupling on the column member 9 so that it remains fixed in the vertical direction and/or is prevented from rotating about the column member 9. The secondary coupling 39 may have a corresponding coupling 39' on the post member 9. The secondary link 39 and the link 39' on the column member together may be referred to as a "locating link" 39.

For example, in one embodiment, the secondary link 39 takes the form of a locator 39, the locator 39 being shaped to key with a corresponding receiver 39' on the post member of the bracket. The retainer 39 and corresponding receiver 39' as shown in fig. 8 take the form of a dumbbell-shaped profile, the retainer 39 comprising an extruded portion which may be attached to or formed with one of the clamp members (in this case the second clamp member 30B) in the form of two extruded flanges bridged by a web portion. The receiving portion takes the form of a correspondingly shaped hole comprising two circular holes bridged by a straight portion. The contours of the retainer 39 and the receiving portion 39' may take different contour shapes. Furthermore, the secondary link 39 and the corresponding column link 39' may also take entirely different forms and are not limited to the forms described herein. Any secondary link 39 and corresponding column link 39' that is capable of positioning the link 22 on the column member 9, holding it vertically fixed and/or preventing rotation about the column member 9 is suitable. Each of the first and

second clamp members

30A, 30B has a complementary closure device 38 for closing and locking the two

clamp halves

30A, 30B when placed and clamped around the post member 9 of the stand. Examples of these will be described in further detail later, but they may take the form of screws, clamps, latches, pins, or other suitable closing mechanisms. To attach the bracket couplers to the first and second brackets, each column coupler is clamped to the respective bracket. Specifically, the post link clamp is opened, then placed around the bracket, then hingedly moved and clamped/fastened about the bracket for insertion of the positioner into the receiver. The coupling is then locked using the closure device.

A handle may be coupled to one of the

column members

13A, 13B to enable movement of the support system. In one example, as shown in fig. 7D, the handle has a horizontal arm, which may take any suitable form, extending outwardly from the post member 9. At one end there is a post coupler 22. It may be a post coupling as previously described, or any other suitable coupling, either permanent (including one-piece), semi-permanent, or removable. At the other end, the arms are bent to have an outward bend and a return to form a handle that helps control the stand. This allows the user to grasp the stent system 10 from a distance.

Fig. 9A-9E illustrate another alternative form of post coupling. In this case, it is not a complete two-piece clamp, but a one-piece clevis 90, which can still be used as a clamp with the aid of a cam lock. The diameter of the inner side of the coupling is commensurate with the diameter of the column member and has

extensions

91A, 91B which extend beyond the column member in use. The post link 90 includes a closure mechanism 93 in the form of a latch that is pivotally attached to one of the extensions 91A. It is a cam-type arrangement having a lever portion 93A and a cam portion 93B and can be flipped closed as shown, for example, to a locked position such that the cam portion abuts the post member 9 and frictionally clamps or otherwise holds the coupling in place. The post coupling 90 can be released by flipping the lever 93 to the open position. As shown, there is a hole 94 for screwing the coupling piece onto the coupling arm 21; there is also a shaped notch 95 (octagonal in this example, but this is not essential) which corresponds to the shaped end of the link arm 21 so that the end of the link arm 21 can be properly seated in the post link 90, the shape of which (if polygonal) would reduce the risk of twisting.

Referring to fig. 10, an alternative embodiment of a bracket coupling 100 is shown. This is an integral version in which the link arm 101 is integral with a post link 102, the post link 102 being in the form of a U-shaped link that can be press/friction fit onto the swivel joint 103 of the caster 16, which is the portion of the caster 16 that is connected to the pedestal of the stand and allows the caster to swivel. The bracket coupling 100 may be made of any suitable material and the post coupling 102 preferably has a suitable resilient material to achieve a press fit. The shape of the coupling 102 will be commensurate with the swivel cross-sectional shape.

Fig. 11 shows another alternative to the bracket coupling 110. The coupling is attached to the base, in particular to the cross-member of the base. The attachment arm 110 is integral with a post coupler 112, the post coupler 112 taking the shape of a rectangular profile commensurate with the cross-sectional profile of each base beam. Each post coupler may be clipped onto and/or sleeved over a portion of the cross beam of each bracket. This will connect the two brackets at the base.

The arm/axle of the wheel base may also have its own interlocking features, such as protrusions or recesses that directly engage each other to provide the coupling. Multiple arms/shafts on the wheel base may be coupled to the arms/shafts on each post-mount wheel base using multiple connecting members/interlocking features. These wheel base coupler embodiments can also be used in conjunction with the various coupler device variations described above, such as with the coupler arm embodiments.

Fig. 12A-12E and 13 illustrate another embodiment of a bracket coupling 20". As previously described, this embodiment of the stand coupling has a coupling arm 21 "and a

post coupling

22A, 22B, but is also hinged by, for example, a hinge 141. The articulated bracket coupling 20 "will now be described in more detail. The hinge 141 allows one end to be detached from the upright member 7 of the respective bracket 13 and to fall and hang vertically (see fig. 13) if the coupling arm 21 "of the bracket coupling 20" is to remain attached to the bracket 13 during storage or transport. This reduces the amount of the coupling arm 21 "protruding from the bracket 13 to which it remains attached. This has various advantages, including providing more efficient storage of the linkage arms 21 "and at least partially mitigating health and safety risks (otherwise personnel may accidentally bump into the extended linkage arms 21" attached to the bracket 13).

The articulated bracket coupling 20 "will now be described in more detail. This embodiment is similar to that previously described (e.g., described in connection with the embodiment of fig. 3E), and may have any of the clamping methods 22, cables 25, and any of the other features previously described. It should also be noted that this articulation may also be combined with any other linkage arm described herein, such as the telescoping linkage arms shown in fig. 7A-7D. The hinge may be used with any of the other variations described above. Accordingly, additional details of the bracket coupling 20 "similar to the other embodiments will not be described herein, and the following description will focus on the articulation.

The articulation is provided by a hinge 141, which hinge 141 may take any suitable form, one non-limiting option being shown in fig. 12A-12E and 13. The hinge 141 may be located at any suitable distance X along the length L of the link arm 21", but is preferably closer to the post link 22B that is permanently/semi-permanently attached to the post member 7 of the bracket 13 (as described with respect to other embodiments). Thus, when the coupling arm 21 "is not being used to couple two brackets 13 together, it can be held on only one bracket 13 and dropped to a position close to the vertical axis of the post member 7 (as shown in fig. 13). The hinge 141 may even be located at (near/adjacent to) one of the

column couplings

22A, 22B.

The hinge 141 divides the link arm into a first portion 142A (length = L-X) and a second portion 142B (length = X), which can pivot/articulate relative to each other. The hinge 141 may be formed of any suitable material, such as plastic and/or metal. Referring to fig. 12A, for example, the hinge 141 includes a receiving (female) hinge portion 141A defined by two arms and a notch therebetween and an engaging (male) hinge portion 141B having a tab. The tab engages in a slot receiving the hinge portion 141A and is secured in place by a pin 143 and hingedly moves/pivots about the pin 143.

The hinge 141 is configured to pivot (hinge-type movement) between about 90 ° in a folded/stored state (see fig. 12D, 12E, 13) and about 180 ° in an extended state, which may be attached to another stand 13 (see fig. 12B, 12C). These angles are non-limiting and any suitable range of angles may be provided. For example, the folded state may exceed 90 °, and may also reach or exceed 90 ° in either direction. As the linkage arm 21 "pivots between the folded and extended states, there is also a series of transition states, one of which is shown in fig. 12A.

The hinge 141 may also have a retainer (in the form of a retaining member or retaining arrangement, lock, stop, latch, or other physical structure) that removably retains the hinge 141 in one of the extended and folded states as desired. In one example shown in fig. 12D, 12E, and 13, the retainer is a combination of an abutment 150 and an edge 151. Specifically, the retainer takes the form of an abutment 150 (stop edge) on the male hinge portion 141B between the base of the protrusion of the male hinge portion and the base of the male hinge portion 141B. For example, there are abutments 150 on both sides of the projection. The edges of the arms 151 of the female hinge portion 141A abut against stop edges 150 on the male hinge portion to limit the pivot range of the hinge 141 to between about 90 degrees (when the edges 151 of the hinge portion 141A abut against stop edges 150-see, e.g., fig. 12E) and about 180 degrees (when the edges 152 abut against stop edges 150-see, e.g., fig. 12C). Between the

edges

151 and 152 is a curved edge 153 to allow movement between the two positions. The

edges

151, 152 of the arms of the female hinge portion 141A may in some cases be considered part of the retainer.

In this embodiment the hinge 141/coupling arm 21 "is pivoted a in a vertical plane (through the length/longitudinal axis of the coupling arm 21", see fig. 12C). However, in other embodiments, the hinge 141/link arm 21 "may pivot in a horizontal plane (through the length/longitudinal axis of the link arm 21"). A horizontal hinge 141 can be used to fold the arms and bring the two coupled brackets 13 closer to each other. Horizontal and vertical are relative to a bracket coupling that is attached horizontally between two brackets during normal use.

The hinge/link arm may also pivot through other planes at other angles. For example, in a variant, in addition to the articulation about the hinge 141, the coupling arm 21 ″ can also be rotated B on/about its longitudinal axis Xc relative to one or both of the column couplings 22 by means of bearings, swivel joints, pivots, ball joints or other rotational connections. For example, the entire coupling arm 21 ″ can be rotated B about its longitudinal axis Xc relative to the column coupling 22 at one and/or both ends to switch from a hinge 141/coupling arm pivoting in the vertical plane (according to a hinge) to a hinge 141/coupling arm pivoting in the horizontal plane. Furthermore, the coupling arm 21 "can rotate about its axis Xc to any relative angle; thus, the plane through which the hinge/linkage arm hingedly moves may pass through the arm 21 at any angle "(that is, the plane is not limited to being merely vertical or horizontal). This means that the hinge 141 can pivot the link arm 21 "in any angular plane (through the length of the link arm). That is, the link arm and/or hinge may be rotated about the longitudinal axis to change the angle of the plane in which the link arm articulates.

In a variant, instead of rotating the coupling arm 21", the hinge 141 may rotate about its longitudinal axis Xc by means of a bearing, a swivel joint, a pivot, a ball joint or other rotational connection forming part of the hinge 141. A combination of rotation of the coupling arm 21 "and the hinge 141 about the axis Xc is also possible. Any of these combinations may change the plane through which the linkage arm articulates.

The hinge 141 allows the two

parts

142A, 142B of the link arm 21 "to pivot about an axis Xp created by a pin (see fig. 13) -for example, when the other part 142B is coupled to a post member of the stand 13, the first part 142A pivots in the direction of arrow a. Fig. 12D, 12E and 13 show the articulated coupling arm 21 "in a fully folded state (about 90 degrees). Figure 13 shows the articulated coupling arm 21 "folded and attached to the upright member 7 of the stand 13 for the power source 12. When not in use, the free ends of the link arms not attached to the bracket may hang downwardly in a compact/folded/stored state. This is a non-limiting example illustrating how articulated linkage arm 21 "works during, for example, storage (e.g., when the linkage arm is not being used to connect a breathing apparatus stand to a power supply stand).

In the embodiment shown, the pivot 143 of the hinge is created by a pin joint, but this is only an example. Any suitable pivot may be used, such as a nut and bolt, a ball joint, a push-on pin joint, and the like. These connections may be accessible and adjustable, or may be overmolded (hidden) and inaccessible. Ball joint type hinges may provide a greater range of pivoting and movement in multiple planes. Ball joints may also be used to connect the shaft to the attachment to provide a greater range of motion at the shaft end of the coupling arm 21". For example, rather than rotating the link arm and/or hinge about the longitudinal axis Xc of the link arm to change the plane through which the link arm articulates; rather, a ball joint or similar device may be used and the hinge 141 may be moved through a hemispherical range (or even more preferably a full spherical range of motion) so that the linkage arm may be articulated to lie in and at any angle within a plane. Of course, ball joint type hinges may be used in combination with the ability to rotate the hinge and/or the linkage arm about axis Xc.

Hinge 141 may also comprise any suitable form of damping material that fits between the joint regions. This will provide wear resistance and sound attenuation of the hinge movement when the

surfaces

151 and 152 abut the stop edge 150.

There may also be a plurality of hinges 141, each taking the form described above, to allow articulation at a plurality of positions.

The articulated linkage arm 21 'embodiment may be combined with the telescoping linkage arm 21' embodiment to provide an articulated telescoping linkage arm.

Preferably, there is at least one hinge. In a variant, the coupling arm may comprise a plurality of hinges 141, so that the coupling arm can be articulated in a plurality of positions on a plane, as previously described. Furthermore, each hinge and/or the coupling arm portion may be rotatable about the axis Xc, and/or each hinge may have a ball joint to enable articulated movement in a hemispherical region or a larger region tending towards the whole sphere. The coupling arm can thus be articulated in a plurality of positions of the coupling arm and/or in a plurality of planes through the longitudinal axis of the coupling arm. For example, the plane may be oriented: through the longitudinal axis of the attachment arm, perpendicular to the longitudinal axis of the attachment arm, and/or at other angles relative to the longitudinal axis of the attachment arm.

4. Breathing equipment, power supply, humidity requirements and power requirements:

some details of the breathing apparatus will be provided, as well as the humidity requirements, power requirements and power supply. This detail is relevant to and can be used with any of the embodiments herein.

The mount system described herein is used with a breathing apparatus 11. Unless the context indicates otherwise, the term "respiratory device" as used in the specification and the indicative claims means any type or form of device, machine, system or apparatus configured to provide and/or generate a flow of gas to a user for respiratory support, respiratory therapy, and includes devices that provide one or more different modes of operation and types of support or therapy, whether flow control, pressure control or otherwise, and includes devices configured or operable to provide flow therapy, high flow therapy, oxygen therapy, positive Airway Pressure (PAP) therapy, such as, but not limited to, continuous Positive Airway Pressure (CPAP) therapy or bi-level CPAP (BiPAP) therapy; the terms "flow therapy device", "respiratory support device", "respiratory assistance device", "high flow device", "non-invasive ventilation (NIV)" may be used to refer to a type of "breathing device" that is context dependent. This list is not exhaustive.

Unless the context indicates otherwise, the term "flow generator" as used in this specification and the indicative claims means any device, system, component, or configuration configured to produce a pressurized gas flow, including but not limited to a blower having an impeller driven by a motor, a compressor, or other source of pressurized gas.

A flow therapy device 11 (as an example of a respiratory device) is shown in fig. 14. The device 11 may include a main housing 120 that houses a flow generator 121 in the form of a motor/impeller arrangement (e.g., a blower), a humidifier 122, a controller 123, and a user interface 124 (e.g., including a display and input means such as buttons, a touch screen, etc.). The controller 123 may be configured or programmed to control the operation of the device. For example, the controller may control components of the apparatus including, but not limited to: operating flow generator 121 to generate a flow of gas for delivery to a patient, operating humidifier 122 (if present) to humidify and/or heat the generated flow, controlling the flow of oxygen into the flow generator blower, receiving user input from user interface 124 for reconfiguration and/or user-defined operation of device 11, and outputting information to a user (e.g., on a display).

The addition of humidity to the airflow may improve the comfort of the treatment, increase patient compliance with the treatment, and prevent or minimize patient airway drying. For high flow therapy, humidifiers are particularly advantageous because high flow without humidity can dry the airways and reduce lung function, e.g. reduce mucociliary transport. Humidity helps to improve comfort by keeping the lungs warm and moist, and helps to improve/maintain healthy mucociliary transport. Humidity also helps maintain physiological stability of the damaged airway and helps with compliance with therapy.

The patient breathing conduit 125 is coupled at one end to an airflow outlet 126 in the housing 120 of the flow therapy device 11. For example, one end of a patient breathing conduit may be equipped with a conduit connector that couples to an electrical/pneumatic connector on the housing 120 of the flow therapy device. A conduit connector of a patient breathing tube has a pneumatic coupling that facilitates gas flow from the device to the conduit, and an electrical connector. The patient breathing conduit 125 is coupled at the other end to a patient interface 127 (e.g., a non-sealed nasal cannula with a manifold 128 and nasal prongs 129). Additionally or alternatively, the patient breathing conduit 125 may be coupled to a face mask, nasal pillow, endotracheal tube, tracheostomy interface, or the like. The flow of gas generated by the flow therapy device 11 may be humidified and delivered to the patient through the cannula 127 via the patient conduit 125. The patient conduit 125 may have heating wires 125A for heating the flow of gas through the conduit to the patient. The heating wire 125A may be under the control of the controller 123. The patient conduit 125 and/or patient interface 127 may be considered part of the flow therapy device 11, or alternatively be peripheral thereto. The flow therapy device 11 with or without the breathing conduit 125 together with the patient interface 127 may form a flow therapy system (breathing apparatus).

The controller 123 may control the flow generator 121 to generate the air flow at a desired flow rate and humidity. The controller 123 may also control the supplemental oxygen inlet to allow delivery of supplemental oxygen, the humidifier 122 (if present) may humidify the gas stream and/or heat the gas stream to an appropriate level, and/or the like. In this configuration, the humidifier 122 includes a water chamber or humidification chamber component through which gases flow, and a heating plate or heater component configured to heat water within the chamber. The flow of gas is directed out to the patient via the patient conduit 125 and the cannula 127. The controller 123 may also control a heating element in the humidifier 122 (e.g., a water chamber through which gases flow or a heating plate of the humidification chamber) and/or a heating element 125A in the patient conduit 125 to heat the gases to a desired temperature for a desired level of therapy and/or patient comfort.

The oxygen inlet may comprise a valve through which the pressurised gas may enter the flow generator or blower. The valve may control the flow of oxygen into a flow generator (e.g., a blower).

Operational sensors

129A, 129B, 129C (such as flow sensors, temperature sensors, humidity sensors, and/or pressure sensors) may be placed at various locations in the flow treatment apparatus 11. Other sensors (e.g., sensors 130, 131) may be placed at different locations on the patient conduit 125 and/or the cannula 127 (e.g., there may be temperature sensors at or near the end of the inspiratory tube). The output from the sensors may be received by the controller 123 to assist the controller in operating the flow therapy device 11 in a manner that provides the appropriate therapy.

The flow therapy device 11 may comprise a high flow therapy device. Unless the context indicates otherwise, 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 a breathing assistance system delivering a targeted humidified flow of breathing gas via a deliberately unsealed patient interface whose flow is generally intended to meet or exceed the patient's inspiratory flow. Typical patient interfaces are unsealed interfaces including, but not limited to, nasal interfaces (e.g., intubation tubes), tracheal interfaces, or oral interfaces. Typical flow rates for adults are generally in the range of, but not limited to, about 15 Liters Per Minute (LPM) to over about 70 liters per minute. Typical flow rates for pediatric patients (e.g., neonates, infants, and children) typically range from, but are not limited to, about 1 liter per minute per kilogram of patient weight to about 3 liters per minute or more per kilogram of patient weight. High flow therapy may also optionally include gas mixing compositions, including supplemental oxygen and/or administration of therapeutic drugs.

By way of example only, high flow therapy is commonly referred to by the common names Nasal High Flow (NHF), humidified High Flow Nasal Cannula (HHFNC), high Flow Nasal Oxygen (HFNO), high Flow Therapy (HFT), or Tracheal High Flow (THF). For example only, the flow rate used to achieve "high flow" may be any of the flow rates listed below. For example, in some configurations, "high flow therapy" for an adult patient may refer to delivery of gas to the patient at a flow greater than or equal to about 10 liters per minute (10 LPM), such as between about 10LPM and about 100LPM, or between about 15LPM and about 95LPM, or between about 20LPM and about 90LPM, or between about 25LPM and about 75LPM, or between about 25LPM and about 85LPM, or between about 30LPM and about 80LPM, or between about 35LPM and about 75LPM, or between about 40LPM and about 70LPM, or between about 45LPM and about 65LPM, or between about 50LPM and about 60 LPM. In some configurations, for a neonatal, infant, or pediatric patient, "high flow therapy" may refer to delivery of gas to the patient at a flow greater than 1LPM, for example between about 1LPM and about 25LPM, or between about 2LPM and about 5LPM, or between about 5LPM and about 25LPM, or between about 5LPM and about 10LPM, or between about 10LPM and about 25LPM, or between about 10LPM and about 20LPM, or between about 10LPM and about 15LPM, or between about 20LPM and about 25 LPM. A high flow therapy device for an adult patient, a neonatal, infant or a pediatric patient may deliver gas to the patient at a flow rate between about 1LPM to about 100LPM or at any subrange of the flow rates described above.

The flow therapy device 11 can deliver any concentration of oxygen (e.g., fdO 2) up to 100% at any flow rate between about 1LPM to about 100 LPM. In certain configurations, any flow rate may be combined with an oxygen concentration (FdO 2) of about 20% -30%, 21% -40%, 30% -40%, 40% -50%, 50% -60%, 60% -70%, 70% -80%, 80% -90%, and 90% -100%. In some combinations, the flow rate may be between about 25LPM and 75LPM in combination with an oxygen concentration (FdO 2) of about 20% -30%, 21% -40%, 30% -40%, 40% -50%, 50% -60%, 60% -70%, 70% -80%, 80% -90%, and 90% -100%. In some configurations, when operating in the manual mode, the flow therapy device 11 may include a safety threshold to prevent the user from delivering too much oxygen to the patient.

High flow therapy may be applied to the nasal and/or oral cavity of the user, or through a tracheostomy interface. High flow therapies may deliver gas to a user at a flow rate that equals or exceeds the expected user's peak inspiratory flow requirements. High flow therapy can produce a flushing effect in the nasopharynx, flushing anatomical dead spaces of the upper respiratory tract with high flow inlet airflow. This allows the generation of a reserve of fresh gas available for each breath, while minimizing re-breathing of nitrogen and carbon dioxide. Meeting inspiratory demand and flushing the airway are also important when attempting to control the patient's FdO 2. High flow therapy may be achieved through a non-sealing patient interface (e.g., a nasal cannula). The nasal cannula may be configured to deliver breathing gas to the user's nares at a flow rate that exceeds the expected user peak inspiratory flow requirement. Nasal high flow also provides dynamic pressure and increased pressure during exhalation. This helps to reduce the patient's breathing rate. The high humidity of the nasal high flow helps to maintain the function of the lungs and airways.

Unless the context indicates otherwise, the term "non-sealing patient interface" or "unsealed interface" as used herein may refer to an interface that provides a pneumatic connection between a patient's airway and a source of airflow (e.g., from airflow generator 121) without completely blocking the patient's airway. In one configuration, the unsealed pneumatic connection may include an obstruction of less than about 95% of the airway of the patient. In another configuration, the non-sealing pneumatic connection may include an obstruction of less than about 90% of the patient's airway. In another configuration, the non-sealing pneumatic connection may include blocking the airway of the patient by about 40% to about 80%. The airway may include one or more of the patient's nares or oral cavity. For nasal cannula, the airway is through the nostril.

The flow generator or blower 121 may include an ambient air inlet to draw ambient room air into the blower. The flow therapy device 11 may also include an oxygen inlet to a valve through which pressurized gas may enter the flow generator 121. The valve may control the flow of oxygen into the flow generator blower 121. The valve may be any type of valve, including a proportional valve or a two-position valve.

The target output parameter may alternatively be pressure. The target pressure may be a constant value, such as Continuous Positive Airway Pressure (CPAP). Alternatively, the target pressure may be a fluctuating value, possibly fluctuating over time with breathing, such as bi-level pressure therapy. In both scenarios, the total flow is not easily constant.

The high flow therapy device 11 provides humidity. Some examples of humidity and power requirements are listed below.

Alternatively, the minimum humidity may be:

providing water vapor at an absolute humidity greater than 12mg/L to a patient having a non-bypass airway, at a flow rate in the range of about 2 to 60 liters/minute, or

Providing water vapor at an absolute humidity greater than 33mg/L to a patient with a bypass airway, at a flow rate in the range of about 10 to 60 liters/minute.

This is achieved by controlling the heating plate and/or heating the breathing tube. Examples of power requirements for a Heating Plate (HP) and a Heating Breathing Tube (HBT) for high flow therapies such as NHF are given below.

In one example, where the breathing apparatus includes a heater rated at about 150W, the heated breathing tube may nominally provide a maximum power of about 65W, but only about 60W in practice due to the 90% load limit. The actual power consumption in use depends to a large extent on the following conditions:

for example, when the dew point of the heater plate is set to 37 ℃, the heater plate can consume about 100W or more at a high flow rate.

For heated breathing tubes, 60W can be consumed at low flow, but typically lower. For example, from 60W at low temperature/low flow to about 30W at high temperature/high flow.

In use, the high flow therapy device 11 uses a power supply that meets the following specifications, as an example:

power supply frequency: 50-60Hz

Supply voltage/current: 100-115V 2.2A (2.4A max), 220-240V 1.8A (2.0A max)

Average power consumption (operating parameters): 165W (37 degrees and 60 liters/minute), 110W (34 degrees and 30 liters/minute). The power consumption during the warm-up phase is higher depending on ambient temperature, altitude and flow resistance (since flow resistance varies with interface selection).

An example portable power supply that can meet the above-described power requirements needed to support the above-described humidity requirements is a 700VA 450W lithium Uninterruptible Power Supply (UPS).

A power supply as described above or meeting the above requirements may be used to power the breathing apparatus 11 and/or may serve as the power supply 12 for the accessory carriage.

These parameters are merely examples and are not limiting.

The above are examples of power requirements that need to be met while making the entire device mobile.

5. The advantages are that:

the described embodiments provide one or more of the following advantages, alone or in combination.

Providing a breathing apparatus, especially when having a humidifying function, requires high power requirements. Balancing mobility and high power requirements is a challenge. To meet power requirements, breathing apparatus have traditionally been plugged into the mains, but this limits mobility because there is a power cable between the apparatus and the mains plug. On the other hand, if a battery is provided, the device may be difficult to receive sufficient power to meet demand, and/or the breathing apparatus may be large and bulky and reduce mobility. Another challenge is the retrofittability and simpler design of the breathing apparatus. Embodiments of the present invention provide a solution that may address or at least ameliorate some or all of these challenges.

For example, one or more embodiments allow for one or more of the following: a) support and movement of the breathing apparatus 11 as the patient migrates so that b) the breathing apparatus can be carried as needed as the patient moves while still remaining connected to the power supply 12 and maintaining the mode of operation and/or providing treatment during the migration, while c) reducing interference with the patient and/or reducing the difficulty of medical personnel migrating the patient and the breathing apparatus 11.

In general, the embodiments described herein facilitate patient mobility while the patient is using the breathing apparatus and maintain continuity of treatment to the patient.

The support system 10 is a modular system in which the respiratory apparatus support 13A, auxiliary support 13B, and support coupling 20 components can be selected and assembled together as desired, and the individual components can be manufactured and sold separately and/or together. Typically, in a hospital environment, there are a number of

racks

13A, 13B and rack couplers 20 that can be interconnected in a modular "mixed-fit" fashion as desired.

In addition to or in lieu of the foregoing, other advantages may include one or more of the following:

to provide mobility to the patient while still receiving treatment.

Providing mobility to the breathing apparatus while maintaining operability and the ability to maintain therapy to the patient.

The power source can provide power to the breathing apparatus, wherein the power source is supported by another support than the support supporting the breathing apparatus.

The breathing apparatus can be powered to provide the flow of gas.

The ability to power the breathing apparatus to humidify the gas flow.

Humidity is important in providing high flow therapy. It helps to be comfortable, helps to keep the airways hydrated, and thus ensures that mucociliary transport can continue. In addition, high flow therapy helps to eliminate carbon dioxide, i.e., eliminate dead zones. An embodiment of the utility model provides an equipment, this equipment can make respiratory equipment continuous operation to can maintain respiratory support, including providing flow and/or humidity. It may provide humidity, for example 37 deg.C dew point or 44mg/L humidity. This requires power to be supplied to the HP to generate sufficient water vapour, while the heating wires need to be heated to reduce the condensation in the tubes. This may be provided by the power supply 12 on the accessory carriage.

The cradle coupling is retrofittable, allowing the breathing apparatus to be powered on existing cradles without built-in batteries. Breathing apparatuses with built-in batteries can be expensive and difficult to manufacture because of the other regulatory and safety requirements. Embodiments of the present invention provide for the use of a power source on a mobile support that is safe and generally approved for use by regulatory agencies, and allows mobility while providing power, allowing for delivery of humidified high flow at appropriate humidity and flow therapy levels during patient flow.

Modularity enables the power accessory cradle with power supply to be interchangeable and connected with any breathing apparatus. In this case, the breathing apparatus does not require its own power supply, such as an internal battery. This makes the design of the breathing apparatus simpler.
