Description

Technical Field

[0001] This utility model relates to the field of pressure chest straps, and more particularly to an adjustable and breathable pressure chest strap. Background Technology

[0002] Postoperative complications are common in cardiac surgery, one of which is subcutaneous emphysema, which can affect the patient's recovery. To address this, compression chest straps are commonly used as an adjunct therapy in clinical practice.

[0003] Existing compression chest straps typically use Velcro for fastening. After wearing, if the tightness needs to be adjusted, the entire strap must be loosened and then tightened again, which is time-consuming and laborious. Furthermore, since existing compression chest straps apply pressure as a whole, and the width and thickness of the human chest cavity vary from top to bottom, this can easily lead to excessive pressure in wider areas and insufficient pressure in narrower areas. Existing compression chest straps also cannot apply different pressures to different areas according to the patient's specific situation. Therefore, this solution proposes an adjustable and breathable compression chest strap. Utility Model Content

[0004] This invention proposes an adjustable breathable pressure chest strap, which solves the problems of inconvenient adjustment of the tightness of existing pressure chest straps and the inability to apply different pressures to different parts of the body.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable breathable compression chest strap includes a compression pad, the compression pad having an internal partition, and both ends of the compression pad being fitted with a tightening mechanism.

[0007] The partition contains an upper airbag, a lower airbag, and a right chest airbag and a left chest airbag located between the upper and lower airbags. An air supply tube is installed on one side of the pressure pad. A latex inflation ball is installed at one end of the air supply tube, and the other end of the air supply tube extends into the partition. A first branch tube communicating with the upper airbag and a fourth branch tube communicating with the lower airbag are installed on the air supply tube. A first valve is installed on the first branch tube, and a fourth valve is installed on the fourth branch tube. A second branch tube communicating with the right chest airbag and a third branch tube communicating with the left chest airbag are installed on the upper airbag. A second valve is installed on the second branch tube, and a third valve is installed on the third branch tube.

[0008] The tightening mechanism includes two connecting parts respectively installed at both ends of the pressure pad. Each connecting part includes a shoulder strap, multiple elastic straps fixed to one end of the shoulder strap, and an adjustment mechanism installed at the other end of the elastic straps. There is a gap between the multiple elastic straps.

[0009] The adjustment mechanism includes a fixed frame fixed to the end of the pressure pad, a rotatably connected roller within the fixed frame, and a limiting component mounted on the fixed frame to limit the rotation of the roller. One end of the elastic strap extends into the fixed frame and is fixed to the outer periphery of the roller, while one end of the roller extends out of the fixed frame and is fixed with a rotating wheel.

[0010] The above technical solution not only allows for convenient and quick adjustment of the tightness of the chest band, but also facilitates the application of different levels of pressure to different locations in the patient's chest cavity, thereby improving the treatment effect and making the patient more comfortable.

[0011] As a further improvement to the above solution, a male Velcro strap is fixed to the front of one of the shoulder straps, and a female Velcro strap that matches the male Velcro strap is fixed to the back of the other shoulder strap. The shoulder straps are provided with multiple ventilation holes.

[0012] The above technical solution allows for the convenient and quick wearing of a chest strap on the patient.

[0013] As a further improvement to the above solution, the top of the fixing frame is provided with a recessed hole coaxial with the scroll. The outer periphery of the portion of the scroll located in the recessed hole is provided with multiple limiting grooves. One end of the fixing frame is provided with a mounting hole. The limiting component includes a limiting rod disposed in the mounting hole and a spring movably sleeved on the outer periphery of the limiting rod. One end of the limiting rod extends to the outside of the mounting hole and is fixed with an adjusting block. The other end of the limiting rod extends into the recessed hole and matches the limiting groove. One end of the spring is fixedly connected to the adjusting block, and the other end of the spring is fixedly connected to the inner wall of the mounting hole.

[0014] The above technical solution relies on the rotation of the roller to achieve the purpose of tightening and loosening the elastic strap, while the limiting rod can easily lock the roller to prevent it from loosening.

[0015] As a further improvement to the above solution, the end of the limiting rod located in the concave hole has a right-angled triangular structure.

[0016] The above technical solution enables the roller to rotate in the forward direction but not in the reverse direction when the limiting rod is stuck in the limiting groove.

[0017] As a further improvement to the above solution, the pressure pad has five electrode holes on its front side, with two electrode holes located on the upper part of the pressure pad, two electrode holes located on the lower part of the pressure pad, and the last electrode hole located in the middle part of the pressure pad.

[0018] The above technical solution allows for easy insertion of electrode pads into the inside of the pressure pad to adhere to the patient's skin surface.

[0019] As a further improvement to the above solution, one end of the valve stem of the first valve, one end of the valve stem of the second valve, one end of the valve stem of the third valve, and one end of the valve stem of the fourth valve all extend to the outside of the front of the pressure pad and are fixed with a knob.

[0020] The above technical solution allows for convenient opening and closing of the first, second, third, or fourth valves via a knob.

[0021] As a further improvement to the above solution, a pressure gauge and a pressure relief valve are installed on the portion of the gas pipeline located outside the pressure pad.

[0022] With the above technical solution, the pressure inside different airbags can be clearly known through the pressure gauge, while the pressure relief valve can conveniently release the air inside different airbags.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. By setting a partition inside the pressure pad and installing an upper airbag, a lower airbag, a left chest airbag, and a right chest airbag inside the partition, and then inflating different airbags with a latex inflation ball, it is possible to conveniently apply different pressures to a certain area according to the actual situation, making the pressure application more precise and the patient's comfort level higher.

[0025] 2. The adjustable mechanism allows for easy adjustment of the elastic straps' tightness by rotating the roller after the two straps are glued together, thus preventing the entire strap from opening and providing greater convenience for medical staff.

[0026] 3. There are gaps between the multiple elastic straps on the same side to facilitate the passage of the drainage bottle, while the electrode holes are designed to make it easy to place the electrodes inside the pressure pad. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] Example 1:

[0036] Please combine Figure 1 - Figure 5 An adjustable breathable compression chest band according to this embodiment includes a compression pad 1. The compression pad 1 has an internal partition, and both ends of the compression pad 1 are equipped with a tightening mechanism. The compression pad 1 is made of elastic breathable fabric. When in use, the compression band 1 is tied to the chest of the patient to achieve the purpose of applying pressure.

[0037] An upper airbag 17, a lower airbag 22, and a right chest airbag 18 and a left chest airbag 21 located between the upper airbag 17 and the lower airbag 22 are installed within the partition. An air supply tube 10 is installed on one side of the pressure pad 1. A latex inflation ball 11 is installed at one end of the air supply tube 10, and the other end of the air supply tube 10 extends into the partition. A first branch tube 13 communicating with the upper airbag 17 and a fourth branch tube 23 communicating with the lower airbag 22 are installed on the air supply tube 10. A first valve 14 is installed on the first branch tube 13, and a fourth valve 24 is installed on the fourth branch tube 23. A second branch tube 15 communicating with the right chest airbag 18 and a third branch tube 19 communicating with the left chest airbag 21 are installed on the upper airbag 17. A second valve 16 is installed on the second branch tube 15, and a third valve 20 is installed on the third branch tube 19. One end of the valve stem of the first valve 14, one end of the valve stem of the second valve 16, one end of the valve stem of the third valve 20, and one end of the valve stem of the fourth valve 24 all extend to the outside of the front of the pressure pad 1 and are fixed with a knob 6. The knob 6 is designed to facilitate the opening and closing of the first valve 14, the second valve 16, the third valve 20, and the fourth valve 24. After the pressure pad 1 is tied to the patient's chest, the latex inflation ball 11 can be pressed continuously to inflate different air bladders. The upper air bladder 17, the lower air bladder 22, the right chest air bladder 18, and the left chest air bladder 21 expand after inflation, thereby further applying pressure to the patient's chest cavity. By controlling the degree of expansion of the upper air bladder 17, the lower air bladder 22, the right chest air bladder 18, and the left chest air bladder 21, different pressures can be applied to different parts.

[0038] A pressure gauge 9 and a pressure relief valve 12 are installed on the part of the air supply pipe 10 located outside the pressure pad 1. The pressure gauge 9 can display the pressure inside the upper airbag 17, the lower airbag 22, the right chest airbag 18, and the left chest airbag 21, thereby achieving precise pressure application, while the pressure relief valve 12 can release the air inside each airbag.

[0039] The tightening mechanism includes two connecting parts installed at both ends of the pressure pad 1. The connecting parts include a shoulder strap 3, multiple elastic straps 2 fixed at one end of the shoulder strap 3, and an adjustment mechanism 4 installed at the other end of the elastic straps 2. There is a gap between the multiple elastic straps 2, and the number of elastic straps 2 is set to 2-3. The gap between the elastic straps 2 is used to facilitate the passage of the drainage bottle.

[0040] One of the shoulder straps 3 has a male Velcro 8 fixed to its front, and the other shoulder strap 3 has a female Velcro 8 fixed to its back. The shoulder straps 3 have multiple ventilation holes 7. The Velcro 8 can be used to quickly attach the two shoulder straps 3 together, making it convenient to quickly put the chest strap on the patient.

[0041] The adjustment mechanism 4 includes a fixed frame 401 fixed to the end of the pressure pad 1, a roller 404 rotatably connected inside the fixed frame 401, and a limiting component installed on the fixed frame 401 to limit the rotation of the roller 404. One end of the elastic strap 2 extends into the fixed frame 401 and is fixed to the outer periphery of the roller 404. One end of the roller 404 extends outside the fixed frame 401 and is fixed with a rotating wheel 402. The rotating wheel 402 facilitates the rotation of the roller 404. When the rotating wheel 402 is rotated in the forward direction to drive the roller 404 to wind up the elastic strap 2, the entire chest strap is tightened. Conversely, when the rotating wheel 402 is rotated in the reverse direction to drive the roller 404 to release the elastic strap 2, the chest strap is loosened, thereby achieving the purpose of conveniently adjusting the tightness of the chest strap.

[0042] The top of the fixing frame 401 has a recessed hole coaxially arranged with the scroll 404. Multiple limiting grooves 403 are evenly distributed on the outer periphery of the portion of the scroll 404 located within the recessed hole. One end of the fixing frame 401 has a mounting hole 405. The limiting assembly includes a limiting rod 406 disposed within the mounting hole 405 and a spring movably sleeved on the outer periphery of the limiting rod 406. One end of the limiting rod 406 extends outside the mounting hole 405 and is fixed with an adjusting block 407. The other end of the spring extends into the recessed hole and matches the limiting groove 403. One end of the spring is fixed to the adjusting block 407, and the other end of the spring is fixed to the inner wall of the mounting hole 405. Under the action of the spring, one end of the limiting rod 406 will be stuck in the limiting groove 403. At this time, the scroll 404 cannot rotate. After the limiting rod 406 is pulled out to the outside of the limiting groove 403, the scroll 404 can be rotated. Thus, the limiting rod 406 is used to lock the scroll 404.

[0043] Five electrode holes 5 are provided on the front of the pressure pad 1, with two electrode holes 5 located on the upper part of the pressure pad 1, two electrode holes 5 located on the lower part of the pressure pad 1, and the last electrode hole 5 located in the middle part of the pressure pad 1. The positions of the electrode holes 5 avoid the airbag setting, and the setting of the electrode holes 5 facilitates the electrode pad to be attached to the patient's skin surface.

[0044] The implementation principle of this embodiment is as follows: When putting on the chest strap for the patient, the pressure pad 1 is placed in front of the patient's chest, and then the two back straps 3 are wrapped around the patient's back and the two back straps 3 are fastened together so that the entire chest strap will not slip off the patient's body. Then the tightness of the chest strap and the pressure on different parts can be adjusted according to the specific treatment needs.

[0045] First, adjust the tightness of the chest strap. If the chest strap is too loose, adjust the different elastic straps 2 in turn. When adjusting, you can first pull one end of the limiting rod 406 out to the outside of the limiting groove 403, and then rotate the rotating wheel 402 in the forward direction, thereby driving the roller 404 to rotate in the forward direction, thereby gradually winding the elastic strap 2 onto the roller 404, and further tightening the chest strap. After the adjustment is completed, release the limiting rod 406 so that one end of the limiting rod 406 is inserted into the limiting groove 403, thereby locking the roller 404. Then perform the same operation on the other elastic straps 2 to further tighten the chest strap. Conversely, after rotating the roller 404 in the reverse direction, the chest strap can be loosened.

[0046] Applying different pressures to different parts can be achieved by inflating different air bladders using the latex inflation balloon 11. When only the first valve 14 is open, pressing the latex inflation balloon 11 allows air to enter the upper air bladder 17 through the air supply tube 10 and the first branch tube 13, causing the upper air bladder 17 to inflate and apply greater pressure to the upper part of the patient's chest cavity. To apply greater pressure to the lower part of the patient's chest cavity, the knob 6 on the valve stem of the fourth valve 24 can be turned to open it. At this time, the air in the air supply tube 10 will also enter the lower air bladder 22 through the fourth branch tube 23, causing the lower air bladder 22 to inflate and further pressurize the lower part of the patient's chest cavity. After opening the second valve 16, air will first enter the upper air bladder 17 and then enter the right chest air bladder 18 through the second branch tube 15. The third valve 20... After opening, the air in the upper airbag 17 will also enter the left chest airbag 21 through the third branch tube 19. After the second valve 16 is opened, the pressure in the right chest airbag 18 will be consistent with the pressure in the upper airbag 17. After closing the second valve 16, the first valve is opened, and then the pressure relief valve 12 is opened, which can release the air in the upper airbag 17, thus keeping only the right chest airbag 18 under pressure. Similarly, the same pressure operation can be performed on the left chest airbag 21. When it is necessary to release the pressure in the lower airbag 22, the fourth valve 24 and the pressure relief valve 12 can be opened at the same time, so that pressure can be applied to different parts of the patient according to different pressure needs. The pressure value displayed by the pressure gauge 9 can clearly show the pressure value in the airbag connected to the air supply tube 10.

[0047] Example 2:

[0048] Combination Figure 5Based on Embodiment 1, this embodiment is further improved in that: one end of the limiting rod 406 located in the concave hole is a right-angled triangle structure. When one end of the limiting rod 406 is stuck in the inner wall of the limiting groove 403, the roller 404 can only rotate in one direction, that is, 404 can only rotate in the forward direction. This can effectively prevent the elastic strap 2 from loosening and also facilitate the forward rotation of the roller 404 to tighten the elastic strap 2.

[0049] The implementation principle of this embodiment is as follows: When one end of the limiting rod 406 is stuck inside the limiting groove 403, the roller 404 cannot reverse, so the elastic strap 2 cannot be loosened. However, at this time, the roller 404 can be rotated in the forward direction to wind the elastic strap 2 onto the roller 404, thereby achieving the purpose of conveniently tightening the elastic strap 2. After the limiting rod 406 is pulled out of the mounting hole 405, one end of the limiting rod 406 will be pushed out of the limiting groove 403. At this time, the roller 404 can be rotated in the forward direction to loosen the elastic strap 2.

[0050] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
