[0041] On the basis of the first embodiment, Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a groove 15 is opened in the sliding seat 1, and a plurality of guide rollers 16 are arranged in the groove 15. The elastic band 3 is overlapped on the plurality of guide rollers 16. Due to the guide rollers 16, when the bracket 9 is pulled left and right, the sliding seat 1 can drive the pressure plate 801 to slide freely on the elastic band 3. The guide rollers 16 play a role in reducing friction, so that the sliding seat 1 can slide on the elastic band 3 more easily, and the service life of the elastic band 3 can also be guaranteed.

[0042] The limiting assembly 11 includes an adjusting plate 111. The two sides of the bottom of the adjusting plate 111 are fixed to the tops of the two clamping assemblies 12. The bottom of the adjusting plate 111 is provided with an arc groove 112, and the arc groove 112 is located between the two clamping assemblies 12.

[0043] Four telescopic rods 113 are fixed to the top of the adjusting plate 111, and the outer sleeve of the telescopic rod 113 is connected with a spring 2 114. The top ends of the telescopic rod 113 and the spring 2 114 are fixedly connected to the top of the bracket 9, and the bottom ends of the telescopic rod 113 and the spring 2 114 are fixed to the top of the adjusting plate 111. After adjusting the position of the pressure plate 801, slowly release the adjusting plate 111, and support the adjusting plate 111 through the elastic force of the spring 2 114, so that the telescopic rod 113 drives the adjusting plate 111 to move downward, and the adjusting plate 111 drives the card strip 122 to be stuck in the card hole 14 through the slide plate 121, so as to achieve the purpose of limiting the sliding seat 1, prevent the sliding seat 1 and the pressure plate 801 from shifting and affecting the effect of applying medicine, and at the same time, the position of the pressure plate 801 is adjusted to meet the purpose of applying medicine to wounds in different positions.

[0044] The clamping assembly 12 includes a slide plate 121, which is slidably connected in the through hole 13. A clamping strip 122 is fixed to the bottom of the slide plate 121, and the clamping strip 122 is clamped in the clamping hole 14. The bottom of the clamping strip 122 is designed to be arc-shaped, so that the clamping strip 122 can be easily inserted into the clamping hole 14, thereby improving the adjustment stability of the sliding seat 1.

[0045] From the above we know:

[0046] The pressure plate 801 is tied to the patient's chest by setting an elastic band 3, and the elastic band 3 is prevented from loosening by the buckle 5. During the process of applying medicine, the medicine is applied to the wound or filled in the gauze layer 804 at the bottom of the pressure plate 801. The portable bracket 9 drives the pressure plate 801 to move upward, and after the pressure plate 801 is moved to just above the wound, the bracket 9 is slowly released. The pressure plate is tightly attached to the wound by the elastic force of the elastic band 3, so that the purpose of applying medicine to the patient is achieved. Since the ball 7 on the top of the pressure plate 801 is slidably connected to the ball groove 6 on the sliding seat 1, the pressure plate 801 can be deflected at multiple angles, so that it can be needled. The pressure plate 801 is adaptively adjusted to the structure around the wound, and the elastic force of multiple springs 803 is used to support the pressure plate 801, so that the pressure plate 801 can fully fit the human skin, further improving the positioning effect of the dressing. During the dressing change process, it is only necessary to lift the bracket 9 to drive the pressure plate 801 to move up through the sliding seat 1, remove the gauze layer 804 for replacement, and then press the pressure plate 801 with the elastic bandage 3. The traditional method of applying medicine with medical tape is abandoned, so as to prevent the sticky medical tape from causing secondary damage to the wound during the pulling process, thereby improving the treatment effect.

[0047] The pressure plate 801 is set to position the medicine dressing. During the process of adjusting the position of the pressure plate 801, the bracket 9 is held and the adjusting plate 111 is squeezed, so that the adjusting plate 111 drives the two slide plates 121 to move upward, so that the slide plate 121 drives the card strip 122 to disengage from the card hole 14. Secondly, the bracket 9 is pulled left and right so that the sliding seat 1 can drive the pressure plate 801 to slide freely on the elastic bandage 3. After adjusting the position of the pressure plate 801, the adjusting plate 111 is slowly released, and the adjusting plate 111 is supported by the elastic force of the spring 2 114, so that the telescopic rod 113 drives the adjusting plate 111 to move downward, so that the adjusting plate 111 drives the card strip 122 to be stuck in the card hole 14 through the slide plate 121, thereby achieving the purpose of limiting the sliding seat 1, preventing the sliding seat 1 and the pressure plate 801 from shifting positions and affecting the medicine dressing effect. At the same time, by adjusting the position of the pressure plate 801, the purpose of applying medicine to wounds at different positions can be met, making it widely used.

[0048] Working principle:

[0049] When in use, the pressure plate 801 is tied to the patient's chest through the elastic band 3, and the buckle 5 is used to prevent the elastic band 3 from loosening. During the process of applying medicine, the medicine is applied to the wound or filled in the gauze layer 804 at the bottom of the pressure plate 801, and the portable bracket 9 drives the pressure plate 801 to move upward, and after the pressure plate 801 is moved to just above the wound, the bracket 9 is slowly released, and the pressure plate is tightly attached to the wound through the elastic force of the elastic band 3, so that the purpose of applying medicine to the patient is achieved. Since the ball 7 on the top of the pressure plate 801 is slidably connected to the ball groove 6 on the sliding seat 1, the pressure plate 801 can be deflected at multiple angles, so that the pressure plate 801 can be adaptively adjusted according to the structure around the wound, and the elastic force of multiple springs 803 is used to support the pressure plate 801, so that the pressure plate 801 can fully fit the human skin. When adjusting the position of the pressure plate 801, hold the bracket 9 and squeeze the adjustment plate 111, the adjusting plate 111 drives the two slide plates 121 to move upward, and the slide plate 121 drives the card strip 122 to disengage from the card hole 14, and then pulls the bracket 9 left and right, so that the sliding seat 1 can drive the pressure plate 801 to slide freely on the elastic band 3. After adjusting the position of the pressure plate 801, slowly loosen the adjusting plate 111, and support the adjusting plate 111 through the elastic force of the spring 2 114, so that the telescopic rod 113 drives the adjusting plate 111 to move downward, so that the adjusting plate 111 drives the card strip 122 to be stuck in the card hole 14 through the slide plate 121, so as to achieve the purpose of limiting the sliding seat 1, and prevent the sliding seat 1 and the pressure plate 801 from shifting their positions and affecting the dressing effect. During the dressing change process, you only need to lift the bracket 9, so that the bracket 9 drives the pressure plate 801 to move upward through the sliding seat 1, remove the gauze layer 804 for replacement, and then press the pressure plate 801 tightly through the elastic band 3.
