Description

Technical Field

[0001] The utility model relates to the technical field of wound care, in particular to a clinical care wound cleaning device. Background Art

[0002] In clinical wound care, pus in the wound needs to be squeezed out and cleaned. During the squeezing process, it is necessary to squeeze from the periphery to the center gradually to promote the expulsion of pus from the wound. In the prior art, a wound cleaning device disclosed in publication number CN116211630A uses an arc-shaped block to squeeze from the periphery to the center, thereby squeezing pus toward the center of the wound. However, during the squeezing process toward the center, the arc-shaped block causes the surface of the human tissue to move, thereby pulling the wound. Moreover, when squeezing toward the center, the arc-shaped block cannot form a closed structure, and pus cannot be squeezed out in the area not squeezed by the arc-shaped block. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides a clinical nursing wound cleaning device, which can gradually squeeze inward from the periphery to expand the squeezing area and facilitate the squeezing of pus.

[0004] To achieve the above-mentioned purpose, the technical solution of the embodiment of the utility model is implemented as follows:

[0005] A clinical nursing wound cleaning device includes a negative pressure tank, an extrusion hood and an adsorption hood. The adsorption hood is connected to the negative pressure tank through a drainage tube. The adsorption hood is used to cover the wound. The extrusion hood is provided above the adsorption hood. The extrusion hood includes a conical shell, an extrusion ring and a conical pad. The conical pad is provided at the bottom of the conical shell. The conical pad and the conical shell are both elastic. A plurality of contraction seams are provided on the upper part of the conical shell. The extrusion ring is located above the conical shell. The conical pad and the conical shell are provided with through holes that pass through the drainage tube.

[0006] Furthermore, the conical housing includes a retaining ring and an elastic sheet, the elastic sheet and the retaining ring are integrally formed, a groove is provided at one end of the elastic sheet close to the retaining ring, and the shrinkage gap is provided between the elastic sheets.

[0007] Furthermore, an adhesive layer is provided in the middle of the elastic sheet, the covering width of the adhesive layer is smaller than the width of the elastic sheet, and the conical pad is connected to the elastic sheet through the adhesive layer.

[0008] Furthermore, the extrusion ring includes an upper ring, a lower ring and a rotating column, the rotating column is provided with a sliding groove for passing the elastic sheet, the upper ring and the lower ring are connected to each other by a connecting rod, and a plurality of cylindrical grooves are provided between the upper ring and the lower ring, and the rotating column is arranged in the cylindrical groove.

[0009] Furthermore, the adsorption cover includes a cover body and a connector, the cover body is conical, the top of the cover body is connected to the connector, and the connector is plugged into the drainage tube.

[0010] Furthermore, the negative pressure tank is an elastic tank, and the drainage tube is provided with a control valve.

[0011] Furthermore, the conical cushion is a conical air-filled bag, and the conical air-filled bag is filled with gas or liquid.

[0012] The beneficial effect of the present invention is that after the extrusion cover covers the periphery of the wound, the outer ring of the conical pad contacts the human tissue. As the extrusion ring is pressed downward, the conical outer shell gradually deforms and pushes the conical pad, so that the conical pad assembly squeezes the human tissue from the outer periphery inward, thereby achieving the effect of squeezing the wound from the outside to the inside, and can squeeze out the pus in the wound more thoroughly. The ability to squeeze gradually inward from the outer periphery expands the squeezing area and facilitates the squeezing of pus. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example 1

[0021] Please refer to the attached Figures 1-3The present application provides a clinical nursing wound cleaning device, comprising a negative pressure cup 1, an extrusion hood 2 and an adsorption hood 3. The adsorption hood 3 is connected to the negative pressure cup 1 through a drainage tube 4. The adsorption hood 3 is used to cover the wound. The edge of the adsorption hood 3 contacts the human tissue to form a relatively closed cavity. After the negative pressure cup 1 forms a negative pressure, a negative pressure can be formed inside the adsorption hood 3 to absorb the pus squeezed out of the wound. The extrusion hood 2 is provided above the adsorption hood 3. The extrusion hood 2 is used to squeeze the tissue around the wound to squeeze the pus out of the wound. The extrusion hood 2 includes a conical shell 5, an extrusion ring 6 and a conical pad 7. The conical pad 7 is provided at the bottom of the conical shell 5. The conical pad 7 and the conical shell 5 are both elastic. The upper part of the conical shell 5 is provided with a plurality of contraction seams 8. The contraction seams 8 can ensure that the conical shell 5 is stably deformed. The extrusion ring 6 is located above the conical shell 5. The conical pad 7 and the conical shell 5 are provided with a through hole 9 passing through the drainage tube 4. When cleaning the wound, the drainage tube 4 is passed through the through hole 9 and the extrusion ring 6 and connected to the adsorption cover 3. Then the adsorption cover 3 covers the wound. The adsorption cover 3 contacts the area around the wound. After the negative pressure tank 1 forms a negative pressure, it sucks the wound. When the pus in the wound is squeezed out, it can be sucked away. In the process of cleaning the wound, the extrusion ring 6 is pressed downward manually to squeeze the center above the conical shell 5, causing the conical shell 5 to deform. After the extrusion cover 2 covers the area around the wound, the outer ring of the conical pad 7 contacts the human tissue. As the extrusion ring 6 is pressed downward, the conical shell 5 gradually deforms and pushes the conical pad 7, causing the conical pad 7 assembly to squeeze the human tissue from the periphery to the inside, thereby achieving the effect of squeezing the wound from the outside to the inside, and can squeeze the pus in the wound more thoroughly. It can squeeze gradually inward from the periphery to expand the squeezing area, making it easier to squeeze out the pus.

[0022] Specifically, the conical shell 5 includes a retaining ring 10 and an elastic sheet 11. The elastic sheet 11 is integrally formed with the retaining ring 10. The retaining ring 10 is located at the bottom. The retaining ring 10 surrounds the human tissue around the wound. The elastic sheet 11 is provided with a groove 12 at one end close to the retaining ring 10. After the top of the elastic sheet 11 is squeezed, the end of the elastic sheet 11 close to the retaining ring 10 is deformed first, so that the elastic sheet 11 can be squeezed from the outside to the inside when the deformation squeezes the conical pad 7, which is convenient for squeezing out the pus. The shrinkage seam 8 is provided between the elastic sheets 11, which can prevent the elastic sheet 11 from conflicting when it is deformed, and can also reduce the upward arching of the middle part of the elastic sheet 11 when it bends downward. When squeezing the tissue around the wound, it can be better squeezed from the outside to the inside, promoting the clean discharge of pus.

[0023] Specifically, an adhesive layer 13 is provided in the middle of the elastic sheet 11, and the covering width of the adhesive layer 13 is smaller than the width of the elastic sheet 11. The conical pad 7 is connected to the elastic sheet 11 through the adhesive layer 13. The adhesive layer 13 fixes the conical pad 7 so that the conical pad 7 squeezes out the pus as the elastic sheet 11 deforms.

[0024] Example 2

[0025] Referring to FIG. 3 , the difference between this embodiment and embodiment 1 is that the extrusion ring 6 includes an upper ring 14, a lower ring 15, and a rotating column 16. The rotating column 16 is provided with a slide groove 17 for passing the elastic sheet 11. When the elastic sheet 11 is deformed, the elastic sheet 11 slides along the slide groove 17. The upper ring 14 and the lower ring 15 are connected to each other by a connecting rod 18, which keeps the position between the upper ring 14 and the lower ring 15 relatively fixed. A plurality of cylindrical grooves 19 are provided between the upper ring 14 and the lower ring 15. The rotating column 16 is disposed in the cylindrical grooves 19 and rotates within the conical grooves. When the elastic sheet 11 is deformed, the rotating column 16 rotates, thereby ensuring that the elastic sheet 11 can slide stably through the slide groove 17.

[0026] Specifically, the adsorption cover 3 includes a cover body 20 and a connector 21. The cover body 20 is conical and is used to cover the wound area, thereby ensuring that negative pressure is formed at the wound area to absorb the squeezed pus. The top of the cover body 20 is connected to the connector 21, and the connector 21 is plugged into the drainage tube 4. After the connector 21 is plugged into the drainage tube 4, the connection is firm, which facilitates the disassembly and replacement of the cover body 20.

[0027] Specifically, the negative pressure tank 1 is an elastic tank, and the drainage pipe 4 is provided with a control valve 22, which is used to control the opening and closing of the overflow pipe.

[0028] Specifically, the conical pad 7 is a conical air bag filled with gas or liquid. The inflated conical air bag can be deformed to squeeze the surrounding tissues of the human body and squeeze out the pus.

[0029] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The scope of protection of the present utility model should be based on the scope of protection of the claims.
