Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a pressure-adjustable air bag blood pressure relief plate. Background Art

[0002] During surgical punctures, after the puncture wound is disinfected, it is compressed with hemostatic cotton and then tied with gauze. This method is inconvenient to operate, and multiple wraps are required to ensure the compression force, and the bleeding inside cannot be seen.

[0003] There are also pneumatic stenosis devices available on the market that can address this problem. These consist of a rigid plastic plate with an airbag at the bottom, an inflation connector, and a bandage around the edge. After treating the puncture wound normally, apply pressure with cotton swabs. The pneumatic stenosis device is then placed on top. After tightening the bandages, the inflation connector is connected to an inflation device (such as a squeezing balloon or syringe). The airbag beneath the plate inflates, increasing the pressure on the wound and promoting wound healing.

[0004] When you need to remove the hemostatic plate, you cannot directly open the inflation connector to release air (there is an on / off valve on the inflation connector) or remove the bandage directly, because too rapid decompression of the wound may cause hematoma or re-bleeding. Therefore, you need to open the inflation connector to release some air first, then release air again after a period of time, repeat this several times, and finally release the air completely, or directly remove the bandage.

[0005] However, it is difficult to accurately limit the opening degree and opening time of the inflation joint. In the event of improper operation, the pressure will still be released too quickly. Utility Model Content

[0006] In view of the above problems, the purpose of the present invention is to provide a pressure-adjustable airbag anti-blood pressure plate, aiming to solve the above technical problems.

[0007] The utility model adopts the following technical solutions:

[0008] The pressure-adjustable airbag anti-sphygmomanometer plate includes a hard plate with straps on both sides of the hard plate, an airbag is provided on the bottom surface of the hard plate, an inflation connector connected to the airbag is provided on the top surface of the hard plate, a window is opened at the center of the hard plate, a rubber block is contained in the window, and a driving component for driving the rubber block to move is also provided on the hard plate, and an elastic rubber sleeve is sealed on the bottom edge of the window, and the rubber block is located in the elastic rubber sleeve.

[0009] Furthermore, the driving assembly includes an upper seat, a center position of which is screwed with a resistance nut, and the bottom of the resistance nut is in resistance to the rubber block.

[0010] Furthermore, the four side walls of the upper seat are provided with guide holes, the top of the rubber block is provided with a cross plate, and the ends of the four supporting arms of the cross plate are located in the corresponding guide holes.

[0011] Furthermore, a positioning ring is provided at the top center of the cross plate, and a ring opening corresponding to the positioning ring is provided in the upper seat.

[0012] Furthermore, the top of the upper seat is located on the outer ring of the interference nut and has an indicator line.

[0013] The beneficial effects of this utility model are as follows: This product, based on existing airbag hemostasis plates, incorporates a rubber block that can move up and down, a drive assembly that drives the block's movement, and an elastic rubber sleeve that covers the rubber block within the airbag. After being applied to the wound, the rubber block is first driven to its lowest position, at which point the elastic rubber sleeve is stretched within the airbag, which is then inflated to expand and generate pressure. When pressure relief is required, the rubber block is controlled to move upward, and the elastic rubber sleeve gradually returns to its original position, thus enabling convenient and precise airbag pressure relief.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0019] like Figure 1-3 As shown, the pressure-adjustable airbag hemostasis plate provided in this embodiment includes a hard plate 1, with straps 2 on both sides of the hard plate 1, an airbag 3 is provided on the bottom surface of the hard plate 1, and an inflation connector 4 connected to the airbag is provided on the top surface of the hard plate 1. A window is opened at the center position of the hard plate 1, and a rubber block 5 is arranged in the window. The hard plate 1 also has a driving component 6 for driving the rubber block 5 to move, and the bottom edge of the window is sealed with an elastic rubber sleeve 7, and the rubber block 5 is located in the elastic rubber sleeve 7.

[0020] In this structure, the airbag is a transparent plastic soft film (elasticity is negligible), and there is an elastic rubber sleeve inside the airbag. The inflation connector is connected to the inflation device, and the gas fills the space between the airbag and the rubber sleeve. After being filled, the airbag is fully inflated and unfolded. Figure 2 The state shown is the initial state of the adhesive block. The adhesive block can move up and down. After the product is tied to the wound with a strap, the adhesive block is located Figure 2 The lowest position shown, at this time the elastic rubber sleeve is stretched in the airbag, and then inflated to expand the airbag to generate compression force.

[0021] When pressure relief is needed, the drive assembly controls the rubber block to gradually move upward, allowing the elastic sleeve to gradually return to its original position. As a result, the effective volume within the airbag increases, and the pressure exerted on the wound decreases. Therefore, simply controlling the position of the rubber block controls the pressure of the airbag, eliminating the need to open the inflation port for deflation, reducing operational complexity and providing more precise control.

[0022] As a specific structure, combined Figure 3 As shown, the drive assembly 6 includes an upper seat 61, with a resistance nut 62 screwed into the center of the upper seat 61. The bottom of the resistance nut 62 resists the rubber block 5. The position of the rubber block is determined by the resistance nut. The resistance nut is rotated forward until the rubber block is at the lowest position, and the elastic rubber sleeve is stretched. After inflation, the internal gas also exerts upward pressure on the elastic rubber sleeve. When the resistance nut is turned in the opposite direction, the rubber block can automatically move upward under the gas pressure and the rebound force of the elastic rubber sleeve, and the operation is simple.

[0023] To ensure stable movement, guide holes 63 are provided on the four side walls of the upper seat 61. A cross plate 64 is located on the top of the rubber block 5. The four arms of the cross plate 64 are positioned within the corresponding guide holes 63. The four arms of the cross plate 64 move up and down within the guide holes. A positioning ring 65 is located at the top center of the cross plate 64, and a ring opening 66 corresponding to the positioning ring is also located within the upper seat 61. The end of the abutment nut is located within the positioning ring, acting as a limiter to prevent the cross plate from deflecting. The ring opening within the upper seat 61 also serves to avoid the positioning ring, thereby reducing the thickness of the entire upper seat and maintaining a beautiful appearance.

[0024] Finally, the top of the upper seat 61 is located on the outer ring of the interference nut and there is an indicator line 67, which can indicate the state angle of the interference nut. For example, it can be rotated 1 and a half turns each time the air is deflated, so that precise operation control can be achieved.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
