Airbag Brown frame

Abstract

The present invention discloses an airbag Brownian frame, which belongs to the technical field of medical equipment. It includes a load-bearing unit and an auxiliary unit, and both ends are attached to one side of a vertical plate, so that the upper end face and the lower end face become a whole. Not only does it strengthen the structural stability of the Brownian frame as a whole, but it also ensures that the upper end face and the lower end face can work together to share the external pressure. The synergistic effect of the overall structure improves the balance of the Brownian frame when bearing loads, and reduces the possibility of each component bearing pressure alone. The ring body and the annular airbag are made of a synthetic rubber material. This material has excellent elasticity and wear resistance, making the airbag Brownian frame more suitable for use in different environments and conditions. It can be inflated into the inner cavity of the wrapping ring and the annular airbag, and the airbag-like structure is wrapped from the outside to the inside instead of the traditional straps. Multiple airbag-like structures can be inflated and deflated independently of each other, so that they can accurately correspond to the position of the blister.

Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an airbag Brownian rack. Background Art

[0002] Patients with leg fractures often have tension blisters on their legs (due to trauma to the legs, the blood circulation around the injured area has been disrupted, causing some capillaries to rupture and become congested. The blood has nowhere to flow out in the muscles, causing swelling and squeezing the moisture in the outer layer of the skin). The traditional Brown frame uses a leg support platform wrapped with straps. When the legs are placed on it, it often squeezes tension blisters and does not form a special space to accommodate the blisters.

[0003] Patent No. CN202022801119.2 discloses an adjustable Brownian traction frame, including a Brownian frame and a load-bearing cloth installed on the Brownian frame, and also includes a suspension assembly installed at the rear end of the Brownian frame and a downward pressure assembly installed on the Brownian frame and close to the rear end; the suspension assembly includes a suspension, a fixed pulley and a support rod, the two ends of the suspension are rotatably installed at the rear end of the Brownian frame, the middle is arranged obliquely upward, a fixed pulley is installed on the outside of the middle position of the suspension, a pull rope is wound around the fixed pulley, one end of the pull rope is provided with a hook, the inner side of the middle position of the suspension is rotatably connected to one end of the support rod, and the other end of the support rod is downwardly connected to the middle connecting rod arranged at the rear end of the Brownian frame; the downward pressure assembly includes a plurality of fixed rods installed on the upper crossbeam of the Brownian frame and a protective shell installed at the upper end of the fixed rod, the protective shell opens downward, an air bag is arranged in the protective shell, and the air bag is connected to the valve nozzle arranged on the upper part of the protective shell. As a further improvement of the utility model, the protective shell is a semicircular empty shell, and a pressure gauge connected to the air bag is arranged on the upper part of the protective shell.

[0004] This patent solves the problem that when the affected limb is placed on a traditional Brownian frame, the patient's comfort is affected because it is supported by a wrapped bandage; but it is not possible to use multiple airbag-like structures that can be inflated and deflated independently so that they can accurately correspond to the location of the blister; for this reason, we propose an airbag Brownian frame to solve the above problem. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an airbag Brownian rack.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An airbag Brown frame includes a bearing unit and an auxiliary unit. The auxiliary unit is vertically arranged at the edge of the upper end face of the bearing unit. The bearing unit includes a bearing frame and an elastic mechanism arranged and installed between the bearing frames. A transverse support plate is horizontally arranged between two opposite groups of the elastic mechanism. First, the main structure of the airbag Brown frame consists of an upper end face and a lower end face. The lower end face is vertically arranged at the edge of the upper end face. This structure helps to provide more stable support during the use of the Brown frame and effectively distribute the load, thereby improving its overall stability; the upper end face bearing unit consists of two parts, namely the bearing frame and the elastic mechanism installed thereon. The two parts are connected by a transverse support plate arranged horizontally to form the basic structure of the upper end face. This design makes the entire upper end face more solid, and can better share and transmit pressure when subjected to external force, thereby improving the service life of the Brown frame. A mounting frame is installed on one side of the bearing frame, and a first wrapping mechanism is arranged at the other end of the mounting frame.

[0008] The support frame includes a first assembly frame and a second assembly frame installed on the upper end surface of the first assembly frame, the first assembly frame and the second assembly frame are connected in series through arranged vertical plates, the upper end surface of the second assembly frame is arranged with ventilation holes, and the support frame includes a first assembly frame and a second assembly frame installed thereon. This structural design enhances the rigidity of the upper end surface and further strengthens the connection through the arranged vertical plates. The ventilation holes arranged on the upper end surface help to provide more uniform support force when the airbag Brown frame is inflated, ensure the stability of the Brown frame, and can fill the gap between the first assembly frame and the second assembly frame with medical instruments, thereby increasing the storage space of the overall device.

[0009] Preferably, the elastic mechanism includes an assembly ring and an elastic sheet arranged between multiple groups of assembly rings, and interlaced vertical cylinders are interspersed between the vertically arranged assembly rings. The elastic mechanism includes an assembly ring and an elastic sheet arranged between multiple groups of assembly rings. This design makes the lower end face more elastic and flexible, and can better adapt to support surfaces of different shapes and sizes. The two ends are attached to one side of the vertical plate, so that the upper end face and the lower end face become a whole, which helps to improve the overall structural stability. The structural design of the elastic mechanism makes the lower end face have excellent elasticity and flexibility. This feature is crucial for adapting to support surfaces of different shapes and sizes in practical applications. Since the support surface may have an irregular shape or undergo slight changes during use, the elasticity and flexibility of the elastic mechanism ensure that the airbag Brownian frame can flexibly adapt to these changes and provide more stable support. This is very practical in the medical field, transportation or other occasions where support is required.

[0010] Preferably, the two ends of the elastic sheet are attached to one side of the vertical plate, so that the bearing frame and the elastic mechanism become a whole. This connection method not only strengthens the structural stability of the Brownian frame as a whole, but also ensures that the upper end face and the lower end face can work together to share the external pressure. The synergistic effect of the overall structure improves the balance of the Brownian frame when bearing loads, reduces the possibility of each component bearing pressure alone, and effectively increases the service life of the Brownian frame.

[0011] Preferably, the auxiliary unit includes an auxiliary bracket and a second wrapping mechanism installed at the bottom of the side end surface of the auxiliary bracket, a third wrapping mechanism is installed at the top of the side end surface of the auxiliary bracket, and a matching mechanism is installed at the top of the other end surface of the auxiliary bracket. The design of these parts enables the Brownian bracket to better adapt to different support surfaces and remain stable during use. In particular, the setting of the inner end surface and the design of the fitting installation enable the lower end surface to better cooperate with the upper end surface to form a more solid support structure. The second wrapping mechanism, the third wrapping mechanism and the first wrapping mechanism can be disassembled, so that the overall device can be used in a variety of situations.

[0012] Preferably, the third wrapping mechanism includes a first wrapping ring and a mounting plate arranged on the side end face of the first wrapping ring, two groups of the mounting plates are connected in series via a transversely arranged transverse through rods, and a second wrapping ring is arranged on the inner end face of the first wrapping ring.

[0013] Preferably, the second wrapping ring includes a ring body and a fitting sleeve arranged on the inner end surface of the ring body, and air inlet holes are arranged on the inner end surface of the fitting sleeve.

[0014] Preferably, the mating mechanism includes a mating ring and an annular airbag arranged on the inner end surface of the mating ring, and the two ends of the mating ring are fitted and installed on the side end surface of the auxiliary bracket. The ring body and the annular airbag are made of a synthetic rubber material. This material has excellent elasticity and wear resistance, making the airbag Brownian frame more suitable for use in different environments and conditions. The inner cavity of the wrapping ring and the annular airbag can be inflated, and the airbag-like structure can be wrapped from the outside to the inside to replace the traditional straps. Multiple airbag-like structures can be inflated and deflated independently of each other, so that they can accurately correspond to the position of the blisters.

[0015] Preferably, the fitting sleeve and the annular airbag are both components made of a synthetic rubber material.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The main structure of the airbag Brownian rack is composed of an upper end face and a lower end face, and the lower end face is vertically arranged at the edge of the upper end face. This structure helps to provide more stable support during the use of the Brownian rack, effectively distribute the load, and thus improve its overall stability. The upper end face bearing unit is composed of two parts, namely the bearing frame and the elastic mechanism installed thereon. The two parts are connected by a transverse support plate arranged laterally, forming the basic structure of the upper end face. This design makes the entire upper end face more solid, and can better share and transmit pressure when subjected to external force, thereby increasing the service life of the Brownian rack.

[0018] 2. The arranged ventilation holes help to provide more uniform support force when the airbag Brown frame is inflated, ensure the stability of the Brown frame, and fill the gap between the first assembly frame and the second assembly frame with medical instruments, thereby increasing the storage space of the entire device.

[0019] 3. The two ends are attached to one side of the vertical plate, so that the upper and lower end surfaces become a whole, which helps to improve the overall structural stability. The structural design of the elastic mechanism makes the lower end surface have excellent elasticity and flexibility. This feature is crucial for adapting to support surfaces of different shapes and sizes in practical applications. Since the support surface may have an irregular shape or undergo slight changes during use, the elasticity and flexibility of the elastic mechanism ensure that the airbag Brownian frame can flexibly adapt to these changes and provide more stable support. This is very practical in the medical field, transportation or other occasions where support is required.

[0020] 4. The two ends are attached to one side of the vertical plate, so that the upper and lower ends become a whole. This connection method not only strengthens the overall structural stability of the Brownian frame, but also ensures that the upper and lower ends can work together to share the external pressure. The synergy of the overall structure improves the balance of the Brownian frame when bearing loads, reduces the possibility of each component bearing pressure alone, and effectively increases the service life of the Brownian frame.

[0021] 5. The ring body and the annular airbag are made of a synthetic rubber material with excellent elasticity and wear resistance, making the airbag Brownian frame more suitable for use in different environments and conditions. The inner cavity of the wrapping ring and the annular airbag can be inflated, and the airbag-like structure can be used to wrap from the outside to the inside to replace the traditional straps. Multiple airbag-like structures can be inflated and deflated independently of each other, so that they can accurately correspond to the position of the blister. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-Figure 6 , Example 1

[0031] An airbag Brown frame includes a bearing unit 1 and an auxiliary unit 2. The auxiliary unit 2 is vertically arranged at the edge of the upper end surface of the bearing unit 1. The bearing unit 1 includes a bearing frame 11 and an elastic mechanism 12 arranged and installed between the bearing frames 11. A transverse support plate 13 is transversely arranged between two sets of opposite elastic mechanisms 12. First, the main structure of the airbag Brown frame consists of an upper end surface and a lower end surface. The lower end surface is vertically arranged at the edge of the upper end surface. This structure helps to provide more stable support during the use of the Brown frame, effectively distribute the load, and thus improve its overall stability; the upper end surface bearing unit 1 consists of two parts, namely the bearing frame 11 and the elastic mechanism 12 installed thereon. The two parts are connected by a transverse support plate 13 arranged transversely to form the basic structure of the upper end surface. This design makes the entire upper end surface more solid, and can better share and transmit pressure when subjected to external force, thereby improving the service life of the Brown frame. A mounting frame 14 is installed on one side of the bearing frame 11, and a first wrapping mechanism 15 is arranged at the other end of the mounting frame 14.

[0032] Example 2

[0033] The carrier 11 includes a first assembly frame 111 and a second assembly frame 112 installed on the upper end surface of the first assembly frame 111. The first assembly frame 111 and the second assembly frame 112 are connected in series through arranged vertical plates 113. The upper end surface of the second assembly frame 112 is provided with ventilation holes 114. The carrier 11 includes a first assembly frame 111 and a second assembly frame 112 installed thereon. This structural design enhances the rigidity of the upper end surface and further strengthens the connection through the arranged vertical plates 113. The ventilation holes 114 arranged on the upper end surface help to provide more uniform support when the airbag Brown frame is inflated, ensure the stability of the Brown frame, and can fill the gap between the first assembly frame 111 and the second assembly frame 112, thereby increasing the storage space of the overall device.

[0035] The elastic mechanism 12 includes an assembly ring 122 and an elastic sheet 121 arranged between multiple groups of assembly rings 122, and an interlaced vertical cylinder 123 is interspersed between the vertically arranged assembly rings 122. The elastic mechanism 12 includes an assembly ring 122 and an elastic sheet 121 arranged between multiple groups of assembly rings 122. This design makes the lower end surface more elastic and flexible, and can better adapt to support surfaces of different shapes and sizes. The two ends are attached to one side of the vertical plate 113, so that the upper end surface and the lower end surface become a whole, which helps to improve the overall structural stability. The structural design of the elastic mechanism 12 makes the lower end surface have excellent elasticity and flexibility. This feature is very important for adapting to support surfaces of different shapes and sizes in practical applications. Since the support surface may have an irregular shape or undergo slight changes during use, the elasticity and flexibility of the elastic mechanism 12 ensure that the airbag Brownian frame can flexibly adapt to these changes and provide more stable support. This is very practical in the medical field, transportation or other occasions where support is required.

[0036] The two ends of the elastic sheet 121 are attached to one side of the vertical plate 113, so that the support frame 11 and the elastic mechanism 12 become a whole. This connection method not only strengthens the structural stability of the Brownian frame as a whole, but also ensures that the upper end face and the lower end face can work together to share the external pressure. The synergistic effect of the overall structure improves the balance of the Brownian frame when bearing loads, reduces the possibility of each component bearing pressure alone, and effectively increases the service life of the Brownian frame.

The design of these parts enables the Brownian bracket to better adapt to different support surfaces and remain stable during use. In particular, the setting of the inner end surface and the design of the fitting installation enable the lower end surface to better cooperate with the upper end surface to form a more solid support structure. The second wrapping mechanism 22, the third wrapping mechanism 23 and the first wrapping mechanism 15 can be disassembled, so that the overall device can be used in a variety of situations.

The two sets of mounting plates 232 are connected in series via a transversely arranged transverse through rod 233 . The second wrapping ring 234 is arranged on the inner end surface of the first wrapping ring 231 .

[0041] The second wrapping ring 234 includes a ring body 2341 and a fitting sleeve 2342 arranged on the inner end surface of the ring body 2341 , and air inlet holes 2343 are arranged on the inner end surface of the fitting sleeve 2342 .

[0042] The mating mechanism 24 includes a mating ring 241 and an annular airbag 242 arranged on the inner end surface of the mating ring 241. The two ends of the mating ring 241 are fitted and installed on the side end surfaces of the auxiliary bracket 21. The ring body 2341 and the annular airbag 242 are made of a synthetic rubber material. This material has excellent elasticity and wear resistance, making the airbag Brownian frame more suitable for use in different environments and conditions. The second wrapping ring 234 and the inner cavity of the annular airbag 242 can be inflated, and the airbag-like structure can be wrapped from the outside to the inside to replace the traditional straps. Multiple airbag-like structures can be inflated and deflated independently of each other, so that they can accurately correspond to the position of the blisters.

[0043] In summary: As a special support structure, the airbag Brownian frame has a wide range of applications in many fields, especially in medical treatment, transportation and other occasions that require support and fixation. This patent provides a novel airbag Brownian frame design with a unique structure that can bring many beneficial effects during use.

[0044] First, the main structure of the airbag Brown frame consists of an upper end face and a lower end face, and the lower end face is vertically arranged at the edge of the upper end face. This structure helps to provide a more stable support during the use of the Brown frame, effectively distribute the load, and thus improve its overall stability.

[0045] The upper end surface bearing unit 1 is composed of two parts, namely, a bearing frame 11 and an elastic mechanism 12 mounted thereon. The two parts are connected by a transverse support plate 13 arranged transversely, forming the basic structure of the upper end surface. This design makes the entire upper end surface stronger, and can better share and transmit pressure when subjected to external force, thereby increasing the service life of the Brownian frame.

[0046] The carrier frame 11 includes a first assembly frame 111 and a second assembly frame 112 mounted thereon. This structural design enhances the rigidity of the upper end surface and further strengthens the connection through the vertical plates 113 arranged in an array. The vents 114 arranged in an array on the upper end surface help to provide a more uniform support force when the airbag Brown frame is inflated, ensure the stability of the Brown frame, and can fill the gap between the first assembly frame 111 and the second assembly frame 112 with medical instruments, thereby increasing the storage space of the overall device.

[0047] The elastic mechanism 12 includes an assembly ring 122 and an elastic sheet 121 arranged between multiple groups of assembly rings 122. This design makes the lower end surface more elastic and flexible, and can better adapt to support surfaces of different shapes and sizes. The two ends are attached to one side of the vertical plate 113, so that the upper end surface and the lower end surface become a whole, which helps to improve the overall structural stability. The structural design of the elastic mechanism 12 makes the lower end surface have excellent elasticity and flexibility. This feature is very important for adapting to support surfaces of different shapes and sizes in practical applications. Since the support surface may have an irregular shape or undergo slight changes during use, the elasticity and flexibility of the elastic mechanism 12 ensure that the airbag Brownian frame can flexibly adapt to these changes and provide more stable support. This is very practical in the medical field, transportation or other occasions where support is required.

[0048] Secondly, the two ends are attached to one side of the vertical plate 113, so that the upper end surface and the lower end surface become a whole. This connection method not only strengthens the overall structural stability of the Brownian frame, but also ensures that the upper end surface and the lower end surface can work together to share the external pressure. The synergistic effect of the overall structure improves the balance of the Brownian frame when bearing loads, reduces the possibility of each component bearing pressure alone, and effectively increases the service life of the Brownian frame.

[0049] In addition, the design of the two ends being attached to the vertical plate 113 also provides convenience for the assembly and disassembly of the airbag Brownian frame. This integral connection method simplifies the manufacturing process, reduces the number of parts, reduces the manufacturing cost, and also facilitates the user to maintain and replace parts of the Brownian frame when necessary.

[0050] The auxiliary unit 2 includes an auxiliary bracket 21, a second wrapping mechanism 22, a third wrapping mechanism 23 and a matching mechanism 24. The design of these parts enables the Brownian bracket to better adapt to different support surfaces and remain stable during use. In particular, the setting of the inner end surface and the design of the fitting installation enable the lower end surface to better cooperate with the upper end surface to form a more solid support structure. The second wrapping mechanism 22, the third wrapping mechanism 23 and the first wrapping mechanism 15 can be disassembled, so that the overall device can be used in a variety of situations.

[0051] The ring body 2341 and the annular airbag 242 are made of a synthetic rubber material, which has excellent elasticity and wear resistance, making the airbag Brownian frame more suitable for use in different environments and conditions. The second wrapping ring 234 and the inner cavity of the annular airbag 242 can be inflated, and the airbag-like structure can be wrapped from the outside to the inside to replace the traditional straps. The multiple airbag-like structures can be inflated and deflated independently of each other, so that they can accurately correspond to the position of the blisters.

[0052] In general, the beneficial effects of the present invention are embodied in the following aspects:

[0053] Enhanced structural stability: Through the vertical setting of the upper and lower end surfaces and the reasonable connection between various components, the airbag Brown frame can provide more stable support during use.

[0054] Improved durability: Structural design and material selection help increase the life of the airbag Brown frame, making it more durable.

[0055] Strong adaptability: The structural design of the upper and lower end surfaces makes the Brownian rack more adaptable to support surfaces of different shapes and sizes, improving its adaptability and versatility.

[0056] Evenly distributed support force: The arrangement of the upper end surface and the specific structural design of the inner end surface help to provide more even support force during inflation, ensuring the stability of the entire Brownian frame.

[0057] Reasonable material selection: The inner end surface made of synthetic rubber has excellent elasticity and wear resistance, and is suitable for use in different environments and conditions.

[0058] In general, this patent provides a novel, stable and durable airbag Brown frame design with broad application prospects.

[0059] The above is the entire working principle of the present invention.
