Detailed Description

The utility model discloses a function gel wound dressing's embodiment for wound surface is restoreed:

the specific structure of the functional gel wound dressing for wound repair of the utility model is shown in fig. 1 to 3, and comprises an upper half part and a lower half part, wherein the upper half part comprises a hard support body 201, and an upper groove 202 is arranged in the middle of the hard support body 201; the lower half includes a hard-fit body 801, with a lower groove 802 provided in the middle of the hard-fit body 801. The lower end of the hard support body 201 is provided with a buckle 203, the upper end of the hard matching body 801 is provided with a clamping groove 803, and the buckle 203 is matched with the clamping groove 803 to fix the upper half part on the lower half part.

The upper groove 202 is vertically penetrated through the rigid support 201, a liquid absorption layer 301 made of polyurethane foam is arranged in the upper groove, and the upper half part further comprises a waterproof dustproof layer 101 fixed above the rigid support 201. The lower groove 802 penetrates through the hard matching body 801 up and down, the hydrogel layer 501 and the hemostatic layer 601 are arranged in the lower groove, the hemostatic layer 601 is made of chitosan fibers, and the chitosan has the functions of deodorization and bacteriostasis besides the hemostatic function. The lower half part also comprises a breathable layer 901 and a release layer 701 which are fixed below the hard matching body 801, wherein the breathable layer 901 is positioned above and is made of polyurethane breathable mucosa, and the release layer 701 needs to be torn off when in use so that the breathable layer 901 can directly contact with the skin of a wound.

In this embodiment, the size of the air permeable layer 901 and the release layer 701 is larger than that of the hard fitting body 801 to ensure that the hard fitting body 801 can be firmly fixed on the mucosa.

The periphery of the lower half part of the hard support body 201 is processed into a special-shaped structure to form the buckle 203, and the lower end surface of the buckle 203 is the lower end surface of the upper groove 202. The upper end of the hard fitting body 801 is bent inward to form the catching groove 803, and the catching groove 803 is higher than the lower groove 802. The groove in the hard mating body 802 that is flush with the groove top of the lower recess 802 forms a mating surface 804 along a plane. The lower end surface of the liquid absorbent layer 301 is higher than the lower end surface of the hard support 201, and the upper end surface of the hydrogel layer 501 is flush with the groove top of the lower groove 802, so that a gap is left between the liquid absorbent layer 301 and the hydrogel layer 501. After the buckle 203 and the clamping groove 803 are installed in place, the lower end surface of the hard support body 201 is supported by the matching surface 804 on the hard matching body 801 to play a positioning role, and different medicines can be added into the gap between the liquid absorption layer 301 and the hydrogel layer 501 according to the diagnosis condition of a doctor. In other embodiments, the upper end surface of the hydrogel layer 501 may be lower than the groove top of the lower groove 802 to leave a gap between the liquid absorbent layer 301 and the hydrogel layer 501; because hydrogel and polyurethane foam all can be out of shape when being pressed, also can not leave the clearance between hydrogel layer 501 and imbibition layer 301, also can directly load powder or liquid medicine between the two at this moment, but use this kind of technical scheme time load powder or liquid medicine between hydrogel layer 501 and imbibition layer 301 and be easy because of receiving the extrusion and run off to cause the effect that the drug effect declines, influence is applied ointment or plaster.

The upper groove 202 is provided with the liquid absorbing layer 301, and the lower groove 802 is provided with the hydrogel layer 501, so that a high-humidity environment can be provided for the wound, and seepage at the wound can be absorbed completely. In other embodiments, the hydrogel layer 501 in the lower recess 802 may also be other functional materials made of hydrogel together with liquid absorbing material or material with other functions; in the case where the functional material having liquid-absorbing property is provided in the lower concave groove 802, the liquid-absorbing layer 301 in the upper concave groove 202 may be another functional material such as a hydrogel material that provides a high-humidity environment only to the wound, a mixture of a hydrogel material and a material having liquid-absorbing property, or the like.

In this embodiment, the outer end surface of the buckle 203 gradually inclines inward from top to bottom to form the clamping surface 204, the arrangement of the clamping surface 204 can facilitate the assembly of the buckle 203 and the clamping groove 803, and the inner diameters of the upper end edge of the clamping groove 803 are equal up and down to prevent the buckle 203 from being separated from the clamping groove 803. This kind of structure of detaining has guaranteed the utility model discloses can only disposable, can send buckle 203 and/or draw-in groove 803 impaired when violently dismantling buckle 203, thereby can avoid the utility model discloses by the patient cross infection situation that repetitious usage and sent. In other embodiments, the inner edge of the upper end of the slot 803 may also be processed to be gradually inclined inward from top to bottom, and at this time, the inner edge of the upper end of the slot 803 forms a clamping surface for facilitating the insertion of the buckle 203 into the slot 803; a clamping groove can be arranged at the lower end of the hard support body 201, and a buckle is arranged at the upper end of the hard matching body 801 to realize the connection between the upper half part and the lower half part.

In other embodiments, the upper groove 202 may also be a sinking groove with only the lower end penetrating through the rigid support 201, and at this time, the upper end surface of the rigid support 201 may have a waterproof and dustproof effect, in which case the waterproof and dustproof layer 101 may also be omitted, but when this scheme is adopted, it needs to consider that an auxiliary structure is arranged on the upper end surface of the rigid support 201 to ensure the air permeability; the air-permeable layer 901 can also be omitted; the hemostatic layer 601 is used for achieving hemostasis, and the hemostatic layer 601 can be omitted under the condition that no corresponding functional requirement exists.
