[0018] Example 1

[0019] This embodiment describes an injection site care device, such as... Figure 1 and Figure 2 As shown, it includes a vertically arranged square frame 3, the cross-section of which is rectangular, the square frame 3 is connected vertically, and the square frame 3 is made of plastic;

[0020] A cover plate 4 is hinged to the top of the frame 3. The cover plate 4 is hinged to the top of the frame 3 and is used to seal the frame 3 to prevent the wound from contacting the outside world, reduce the pollution of the wound by the external environment, and facilitate the healing of the wound. The cover plate 4 is made of plastic.

[0021] The bottom of the frame 3 is horizontally fixed with non-woven fabric 9. The non-woven fabric 9 is horizontally fixed at the lower end of the frame 3. The non-woven fabric 9 separates the frame 3 from the patient's skin. The non-woven fabric 9 absorbs the oozing blood and body fluids, keeping the wound clean and promoting wound healing. The non-woven fabric 9 is a new type of fiber product made of oriented or random fibers. As a new generation of environmentally friendly material, it has the characteristics of moisture resistance, breathability, flexibility, light weight, easy decomposition, non-toxicity, non-irritation and low price.

[0022] The non-woven fabric 9 has a pressure block 8 embedded in the middle. The non-woven fabric 9 has a through groove that is open from top to bottom. The pressure block 8 is horizontally placed in the through groove. The wound is pressed by the pressure block 8. The pressure is applied to avoid bleeding and exudation from the wound, which is conducive to wound healing. The pressure block 8 is made of rubber.

[0023] Elastic bands 1 are fixed on both the left and right sides of the frame 3. The elastic bands 1 are elastic and can be adjusted according to the patient's reminders to wear the frame 3 on the wound.

[0024] Two first airbags 2 are fixed to the inner wall of the elastic band 1, respectively fixed to the side of the elastic band 1 closest to the patient's limb. When the elastic band 1 wraps around the patient's limb, the patient's limb compresses the first airbag 2, driving the air flow within the first airbag 2. A second airbag 5 is installed inside the frame 3, installed at the top of the frame 3 and resting against the bottom of the cover plate 4. When the second airbag 5 inflates, it pushes the connecting column 6 downward. A channel 7 is provided inside the frame 3 to connect the first airbag 2 and the second airbag 5. One end of the left channel 7 connects to the left first airbag 2, and the other end connects to the left end of the second airbag 5. One end of the right channel 7 connects to the right first airbag 2, and the other end connects to the right end of the second airbag 5. The two first airbags 2 are connected to the second airbag 5 through the channel 7. 5. The connection is continuous; a connecting post 6 is vertically fixed at the bottom of the second airbag 5, and the lower end of the connecting post 6 is fixed to the pressure block 8. The connecting post 6 is located between the second airbag 5 and the pressure block 8, with the upper end of the connecting post 6 in contact with the second airbag 5 and the lower end of the connecting post 6 fixed to the pressure block 8. This section as a whole constitutes a driving component for pushing the pressure block 8 to press the puncture point. When the driving component is in use, the elastic band 1 is wrapped around the patient's limb, and the two first airbags 2 are squeezed by the patient's limb, forcing the gas in the first airbags 2 into the second airbag 5. After the second airbag 5 is inflated, it expands and presses down on the connecting post 6, pressing the pressure block 8 tightly onto the wound to prevent wound bleeding and exudation, and to facilitate wound healing. Of course, the driving component can also have a trachea between the first airbag 2 and the second airbag 5, connecting the first airbag 2 and the second airbag 5 through the trachea.

[0025] In this embodiment, the frame 3 is placed on the wound, the pressure block 8 is aligned with the wound, and the frame 3 is worn on the limb by passing two elastic bands 1 around the patient's limb. When the elastic bands 1 are tightened, the pressure block 8 is moved by the drive component to compress the wound, reduce bleeding and exudation, keep the wound clean, and promote wound healing.

[0026] Example 2

[0027] This embodiment further illustrates the technology, such as Figure 1As shown, a pressure plate 12 is fixed to the upper end of the connecting column 6, and the second airbag 5 abuts against the pressure plate 12. The pressure plate 12 has an arc-shaped structure with the opening facing upward. The arc-shaped pressure plate 12 is more compatible with the second airbag 5, increases the contact area between the connecting column 6 and the second airbag 5, effectively utilizes the thrust generated after the second airbag 5 expands to push the pressure block 8, and at the same time improves the service life of the second airbag 5.

[0028] The bottom of the pressing block 8 has an upward-facing groove, in which chitosan fiber 10 is fixed. The groove is located at the bottom of the pressing block 8 and extends vertically upward. Chitosan fiber 10 is a prior art material. Chitosan fiber is a fiber made by removing acetyl groups from chitin through concentrated alkali treatment. Chitosan raw material is dissolved in acetic acid solution, filtered and degassed to make spinning solution, which is then solidified into solid fiber through spinning process. After further stretching, the finished fiber is obtained. It has excellent biocompatibility and safety and is often used in surgical sutures, medical dressings, artificial skin, etc. It also has broad-spectrum antibacterial, anti-mildew and deodorizing, moisture-absorbing and quick-drying, and rapid hemostatic properties. Chitosan fiber 10 can help wounds stop bleeding quickly and prevent exudation, which is beneficial to wound healing.

[0029] The pressure block 8 is made of transparent material, specifically transparent rubber. The transparent pressure block 8 allows medical staff to observe the blood staining status of the chitosan fibers 10, which helps determine whether hemostasis is successful and to take timely countermeasures, thus promoting wound healing.

[0031] This embodiment further illustrates the technology, such as Figure 1 As shown, the movable end of the elastic band 1 is equipped with a buckle 11, and the right end of the left elastic band 1 and the left end of the right elastic band 1 are equipped with buckles 11. The movable ends of the two first airbags 2 are connected by the buckles 11. Alternatively, the elastic band 1 can be fixed to the limb by wrapping or knotting.

[0032] like Figure 1 As shown, the rear end of the cover plate 4 is hinged to the rear end of the frame 3 via a hinge. One end of the hinge is fixed to the top of the rear side wall of the frame 3 by a screw, and the other end is fixed to the rear end of the cover plate 4 by a screw, which facilitates the flipping of the cover plate 4.

[0033] The cover plate 4 and the frame 3 are connected by a latch 13. The latch is installed on the front side wall of the frame 3. The front end of the cover plate 4 is equipped with a matching buckle 13. By inserting the buckle into the latch 13, the cover plate 4 is fixed to the top of the frame 3, separating the wound from the outside world and forming an independent space, reducing the impact of the external environment on the wound.
