Description

Technical Field

[0001] This invention relates to the field of rehabilitation assistive devices, and in particular to a breathing vest with a multi-point pressure regulation mechanism. Background Technology

[0002] Breathing vests are commonly used for physical therapy or auxiliary training in chest and lung rehabilitation. The standard structure consists of multiple air sacs distributed on the main body of the vest. The air sacs are inflated by an external air source to compress the patient's chest and abdominal muscles, assisting the patient in respiratory muscle training or expectoration. During rehabilitation training, different parts of the body have different pressure requirements.

[0003] Conventional breathing vests typically use a centralized air supply system, which cannot provide targeted mechanical obstruction of the air intake channels for individual air bladders. This makes it difficult for the vest to apply pressure to different parts of the body to meet the diverse needs of local rehabilitation treatment. In order to achieve independent adjustment of air intake, some vest devices attempt to add external throttling components to the air intake lines. However, when wearing the vest, patients need to perform movements such as bending, turning, etc. The exposed adjustment components are easily scratched or bumped by the patient's arms or clothing during these movements. Physical contact can change the initial setting of the adjustment components, causing the originally adjusted air intake to deviate. This results in fluctuations and instability in the internal air pressure of the corresponding air bladder, affecting the actual rehabilitation effect.

[0004] Therefore, this invention proposes a breathing vest with a multi-point pressure regulation mechanism to address the shortcomings of the prior art. Summary of the Invention

[0005] In view of the problems in the existing technology of breathing vests, such as the inability to independently control the air intake of local air bags due to the unified air supply, and the fact that the external adjustment mechanism is easily touched during patient movement, causing the set angle to deviate and resulting in air pressure instability, the present invention aims to provide a breathing vest with a multi-point pressure adjustment mechanism that has been structurally improved and can effectively solve the above problems.

[0006] This invention provides a respirator vest with a multi-point pressure adjustment mechanism, comprising a respirator vest body and an air bladder fixedly connected to the outer wall of the respirator vest body. An air inlet pipe for delivering gas is connected to the side of the air bladder. A sliding groove penetrating the outer wall of the air inlet pipe is formed. An airflow control adjustment component is disposed within the internal cavity of the air inlet pipe. The adjustment component includes a fixing frame and a rotating ring. The fixing frame is fixedly connected to the inner wall of the air inlet pipe, and a through hole for airflow is formed at the center of the fixing frame. The rotating ring is fitted and rotates within the fixing frame. A force-operated pull rod is fixed to the outer wall of the rotating ring, which is connected to the outer wall of the fixed frame. The pull rod passes through the sliding groove and is slidably connected to the inner wall of the sliding groove. A transmission fixed rod is also fixed to the outer wall of the rotating ring. The outer wall of the fixed rod is slidably connected to the inner wall of the swing block. The swing block is fixedly connected to one end of the rotating column. The rotating column passes through and is rotatably connected to the side wall of the fixed frame. A guide plate for blocking airflow is fixed to the other end of the rotating column. The guide plate is located in the through hole and is rotatably connected to the inner wall of the fixed frame.

[0007] The outer end of the pull rod is connected to a fixed component that limits the trajectory. The fixed component includes a rotating block and a threaded post. The threaded post is fixedly connected to the end face of the pull rod, and the inner wall of the rotating block is rotatably connected to the outer wall of the threaded post.

[0008] A rubber ring that increases frictional resistance is fixedly connected to the outer wall of the rotating block. The rubber ring moves along the length of the threaded column with the rotating block and is squeezed and abuts against the outer wall of the air intake pipe.

[0009] The airbags and the air inlet pipe are provided in multiple locations corresponding to the stress area, and the multiple airbags are distributed at intervals on the outer wall of the main body of the breathing vest.

[0010] The guide plate, the rotating column, the swing block, and the fixing rod are all provided in multiple sets, and the multiple sets of guide plates are distributed in a ring array on the inner wall of the fixing frame.

[0011] The sliding groove extends in an arc shape along the circumference of the air intake pipe, and the pull rod slides within the sliding groove along the arc-shaped extension direction of the sliding groove.

[0012] The present invention has the following beneficial effects: 1. This invention solves the problem that existing breathing vests cannot independently intervene in the air intake volume of different parts of the airbag by setting a rotating ring and swing block driven by a pull rod inside the air intake pipe, and relying on the linkage of the mechanical structure to drive multiple guide plates to rotate synchronously to change the physical obstruction area of ​​the air intake channel. This achieves the technical effect of realizing multi-point independent airflow control and precise setting of internal air pressure for airbags in different distribution areas of the vest.

[0013] 2. This invention, by using a rotating block and a rubber ring screwed into a threaded post on the outside of the pull rod, relies on the threaded thrust to force the rubber ring to abut against and squeeze the outer wall of the air intake pipe to generate structural friction force, thereby limiting the sliding trajectory of the pull rod. This solves the problem that existing external adjustment structures are easily touched and deviate in state when the user is active, and achieves the technical effect of firmly restricting the internal flow guiding structure to a specific control position to maintain the long-term stability of the local pressure of the airbag.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please refer to Figures 1 to 7This invention provides a breathing vest with a multi-point pressure adjustment mechanism, which solves the problems in the prior art where breathing vests cannot accurately and stably adjust the air intake of the airbag independently, and where the internal mechanism is easily displaced due to external touch after adjustment, resulting in pressure instability.

[0018] The breathing vest with a multi-point pressure regulation mechanism includes a breathing vest body 1 and an airbag 4 fixedly connected to the outer wall of the breathing vest body 1. The breathing vest body 1 serves as the basic wearable structure to carry various functional components. The airbag 4 applies wrapping pressure to specific parts of the human body by inflating. There are multiple airbags 4 and air inlet pipes 5. Multiple airbags 4 are distributed at intervals on the outer wall of the breathing vest body 1. The multiple sets of airbags 4 correspond to different pressure areas of the human body to achieve independent pressure regulation of multiple parts. The airbag 4 is connected to the air inlet pipe 5. An external air supply device delivers gas to the inside of the airbag 4 through the air inlet pipe 5. The outer wall of the air inlet pipe 5 is provided with a sliding groove 204, which extends along the circumference of the air inlet pipe 5.

[0019] An adjustment component 2 is provided inside the air intake pipe 5. The adjustment component 2 mechanically controls the airflow entering the airbag 4. The adjustment component 2 includes a fixed frame 201 and a rotating ring 205. The fixed frame 201 is fixedly connected to the inner wall of the air intake pipe 5 as an internal support carrier. The fixed frame 201 has a through hole 202, which provides a channel for airflow to pass through the fixed frame 201 and enter the airbag 4. The rotating ring 205 is sleeved on and rotatably connected to the outer wall of the fixed frame 201. A pull rod 203 is fixed to the outer wall of the rotating ring 205. The outer operating end of the pull rod 203 passes through the sliding groove 204 and is slidably connected to the inner wall of the sliding groove 204. The pull rod 203 extends along the sliding groove 204. The directional sliding mechanism is fitted within the sliding groove 204. When the operator pulls the lever 203, it slides circumferentially along the inner wall of the sliding groove 204. The synchronous sliding process of the lever 203 drives the rotating ring 205 to rotate outside the fixed frame 201. When the lever 203 moves along the inner wall of the sliding groove 204, it is limited and guided by the wall of the air intake pipe 5. The mechanical guiding relationship ensures the stability of the rotating ring 205 during its rotation on the outer wall of the fixed frame 201. The rotation of the rotating ring 205 provides the basic driving force for the subsequent change of the opening and closing area of ​​the airflow channel. The inner diameter of the through hole 202 is adapted to the flow section of the air intake pipe 5 to ensure the gas flow rate under maximum inflation conditions.

[0020] The breathing vest with a multi-point pressure adjustment mechanism also includes a fixed rod 206, a swing block 207, a rotating column 208, and a guide plate 209 to regulate airflow. The fixed rod 206 is fixedly connected to the outer wall of the rotating ring 205, and the outer wall of the fixed rod 206 is slidably connected to the inner wall of the swing block 207. The swing block 207 is fixedly connected to one end of the rotating column 208, which passes through and is rotatably connected to the side wall of the fixed frame 201. When the pull rod 203 is pulled to rotate the rotating ring 205, the fixed rod 206 on the outer wall of the rotating ring 205 moves synchronously in a circular motion. During the movement of the fixed rod 206, relative sliding occurs on the inner wall of the swing block 207. The sliding force causes the swing block 207 to rotate and deflect with the rotating column 208 as the support point. The other end of the rotating column 208 is fixed with a guide plate. 209, the guide plate 209 is located in the through hole 202 inside the fixed frame 201 and is rotatably connected to the inner wall of the fixed frame 201. The deflection of the swing block 207 directly drives the rotating column 208 to rotate synchronously in the side wall of the fixed frame 201. The rotation of the rotating column 208 drives the guide plate 209 fixed at its end to change the flip angle in the through hole 202. There are multiple guide plates 209, rotating column 208, swing block 207 and fixed rod 206. Multiple guide plates 209 are distributed in a ring array on the inner wall of the fixed frame 201. Multiple transmission structures make the multiple guide plates 209 distributed in the ring array rotate synchronously. The multiple guide plates 209 surround and change the physical blocking area between each other. The air intake of the airbag 4 is precisely controlled by changing the actual gas flow diameter of the through hole 202.

[0021] Based on the above embodiments, the respirator with a multi-point pressure adjustment mechanism also includes a preferred technical solution. As a preferred embodiment, to lock the angle position of the internal mechanical mechanism after adjusting the air intake of the airbag 4 to prevent pressure instability caused by user movement, a fixing component 3 is connected to the outer end of the pull rod 203. The fixing component 3 includes a rotating block 301 and a threaded post 302. The threaded post 302 is fixedly connected to the outer end face of the pull rod 203 as a threaded screw base. The inner wall of the rotating block 301 has an internal thread structure, and the inner wall of the rotating block 301 is rotatably connected to... A rubber ring 303 to increase contact friction is fixedly connected to the outer wall of the threaded column 302 and the outer wall of the rotating block 301. When the rotating block 301 is turned, the rotating block 301 rotates relative to the outer wall of the threaded column 302. During the rotation process, the rubber ring 303 moves along the length direction of the threaded column 302 with the rotating block 301. The rubber ring 303 moves towards the direction of the air intake pipe 5 and finally abuts against the outer wall of the air intake pipe 5. The friction generated by the rubber ring 303 abutting against and squeezing the outer wall of the air intake pipe 5 firmly restricts the pull rod 203 to the current adjustment position of the sliding groove 204.

[0022] The working principle of the breathable vest with a multi-point pressure regulation mechanism of the present invention is as follows: External equipment delivers gas into the intake pipe 5. The airflow passes through the through hole 202 inside the fixed frame 201 and enters the airbag 4, causing it to inflate and wrap around a specific part of the human body. When it is necessary to adjust the internal pressure of a certain airbag 4, the operator moves the pull rod 203 to slide it circumferentially along the inner wall of the sliding groove 204. The translation of the pull rod 203 drives the fixed rotating ring 205 to rotate synchronously on the outer wall of the fixed frame 201. When the rotating ring 205 rotates, it drives the fixed rod 206 fixed to its outer wall to move synchronously. During the movement, the fixed rod 206 slides relative to the inner wall of the swing block 207 and generates a mechanical pulling force. The power forces the swing block 207 to deflect around the rotating column 208 as the axis. The deflection of the swing block 207 directly drives the rotating column 208 to rotate synchronously within the side wall of the fixed frame 201. The rotation of the rotating column 208 drives the guide plate 209 fixed at one end of its inner side to flip within the through hole 202. Multiple sets of transmission mechanisms work together to make the multiple guide plates 209 distributed in a ring array change their angles synchronously. The airflow through the through hole 202 is controlled by the change in the enclosed area of ​​the multiple guide plates 209. The mechanical linkage mechanism converts linear sliding into the synchronous opening and closing of the guide plates 209, thus precisely controlling the internal air pressure of a single airbag 4.

[0023] After the angle of the guide plate 209 is adjusted, the operator turns the rotating block 301 on the fixing component 3 clockwise. The rotating block 301 is screwed inward on the outer wall of the threaded column 302 through the threaded structure on the inner wall. The screwing action of the rotating block 301 simultaneously pushes the rubber ring 303 fixed on its end face to move inward until the rubber ring 303 tightly abuts against and squeezes the outer wall of the air intake pipe 5. After the rubber ring 303 is squeezed and deformed, a high-intensity frictional force is generated between it and the outer wall of the air intake pipe 5. This frictional force firmly locks the pull rod 203 in the adjustment position of the sliding groove 204. The locking method of threaded screwing and rubber friction avoids the problem of the angle of the guide plate 209 being offset due to the user's body movement touching the pull rod 203, and maintains the stability of the state after multi-point pressure adjustment. When it is necessary to adjust the air intake again, the rotating block 301 is loosened counterclockwise to release the rubber ring 303 from the air intake pipe 5, which can release the movement restriction on the pull rod 203.
