Description

Portable moist applying ointment or plaster

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to portable moist applying ointment or plaster.

Background

The 'moist healing theory' proves that the moist environment on the surface of the wound can promote the healing of the wound, while the dressings such as gauze, sterilized absorbent cotton and the like which are commonly used in the traditional wound nursing can only provide physical protection, and the dressings are easy to adhere to the wound and the surface of the wound is easy to breed bacteria. Meanwhile, the sterile operation process is complicated, and the operation of professional medical personnel is needed to ensure the cleanness of the wound surface.

SUMMERY OF THE UTILITY MODEL

In view of the deficiencies of the prior art, it is an object of the present disclosure to provide a portable moist applicator which addresses at least one technical problem in the background art.

The purpose of the disclosure can be realized by the following technical scheme:

a portable moist applicator comprising a composite dressing comprising a soft silicone contact layer, a hydrophilic polyurethane foam layer and a polyurethane film; the antibacterial polyurethane foam film comprises a soft silicone contact layer, a hydrophilic polyurethane foam layer compounded on the soft silicone contact layer, antibacterial liquid loaded in a pore structure of the polyurethane foam layer, and a polyurethane film arranged on the hydrophilic polyurethane foam layer;

the hydrophilic polyurethane foam layer is embedded with a handheld part;

one end of the handheld part is exposed out of one side of the hydrophilic polyurethane foam layer.

In some disclosures, the composite dressings are arranged in plurality side by side, and adjacent composite dressings are connected through a tear line.

In some disclosures, both sides of the tear line are respectively connected to one of the soft silicone contact layer, the hydrophilic polyurethane foam layer, and the polyurethane film adjacent to the composite dressing.

In some disclosures, chitosan or lysozyme-antimicrobial peptide is included in the antimicrobial liquid.

In some disclosures, the handle is elongated.

In some disclosures, the material of the handle is polycarbonate.

In some disclosures, the applicator includes a sterile portion that is disposed separately from the composite dressing.

In some disclosures, the sterilizing portion includes three sterilized iodophor swabs.

In some disclosures, the antiseptic portion and the composite dressing are packaged by an overwrap; the extranal packing is provided with dressing cell and disinfection cell, disinfection portion arranges in the disinfection cell, compound dressing arranges in the dressing cell.

In some disclosures, the overwrap is provided with a tear-out portion.

The beneficial effect of this disclosure:

1. providing a sterile moist microenvironment for wound healing;

2. the detachable handheld structure can furthest ensure the sterility of the dressing change process, and provides a convenient dressing change way which can be operated by a patient who is not in hospital;

3. the packaging design of the combined disinfection tool and the composite dressing provides the necessary conditions for emergency treatment of wounds for families or outdoor players.

Drawings

In order to more clearly illustrate the embodiments or technical solutions of the present disclosure, the drawings used in the embodiments or technical solutions of the present disclosure will be briefly described below, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

Fig. 1 is a front view structural schematic diagram of a portable moist application provided by the present invention;

FIG. 2 is a schematic side view of a portable wet-applied composite auxiliary material according to the present invention;

fig. 3 is a schematic diagram of a layered structure of a portable wet-applied composite auxiliary material according to the present invention.

Detailed Description

The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the embodiments described are only some embodiments of the present disclosure, rather than all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

As shown in fig. 1 to 3, a portable moist application comprises a composite dressing 3 composed of a soft silicone 8, a polyurethane foam 7, a polyurethane film 6 and an antibacterial component, a hand-held portion 5, a disinfection tool 2 and an outer package 1. The soft silicone contact layer 8 can be gently attached to the wound surface and the surrounding skin, does not adhere to the wound surface, reduces the damage to the new granulation and promotes the growth of capillary vessels, and plays a role in reducing pain and eliminating swelling; the polyurethane foam layer 7 has a porous structure, can load antibacterial drugs and has the heat preservation and moisture preservation capabilities;

the polyurethane film 6 has adhesiveness and has waterproof and bacterium-isolating functions; the antibacterial component is a liquid containing chitosan and lysozyme-antibacterial peptide, and can provide an aseptic wet environment for wound healing;

the composite dressing 3 and the handheld part 5 can form a removable integral structure in an embedded mode, the dressing can be attached to a disinfected wound surface by using the handheld part 5, and the handheld part is removed after the dressing is used, so that the sterile and simple dressing changing process is kept;

the sealed package 1 is sterilized by high-temperature steam, so that the sterility of the internal dressing is ensured.

The utility model discloses a working process: opening disinfection cells in the outer package at the lower third of the hand-held part through the gap, and disinfecting the wound surface by using an iodophor cotton swab 2; continuously opening the composite dressing unit cells along the tearing part, holding the tail end of the handheld part, and attaching the composite dressing 3 to the disinfected wound surface, wherein the composite dressing is not touched by hands or other objects in the process;

after the composite dressing 3 is attached to the wound surface, the hand-held part 5 is slightly forcibly pulled out of the composite dressing 3, and the dressing change operation can be completed.

In some cases, of course, a plurality of composite dressings 3 are provided side by side, and adjacent composite dressings 3 are connected by a tear line 4; the tear line 4 can adjust the size of the composite dressing 3 according to the size of the wound surface, so that the dressing can achieve the effect of fitting the wound surface more.
