Description

Hemostatic plaster

Technical Field

The utility model relates to the field of medical equipment, in particular to a hemostatic patch.

Background

In medical treatment, doctors need to carry out intravenous injection or blood sampling on patients, and when a disposable intravenous infusion needle or a disposable blood taking needle is pulled out, hemostatic cotton is pressed on wounds to prevent germs from infecting the wounds, so that the wounds are simply disinfected. When a patient presses the hemostatic cotton by using one or two fingers, the patient cannot accurately judge the position of a puncture bleeding point, so that the problem of inaccurate pressing position is easily caused, and blood spots at a wound are easy to deposit or excessive bleeding is caused by insufficient hemostasis due to inaccurate pressing position; sometimes, the pressed wound may be sore for several days due to the exertion of too much force; in addition, although hemostatic cotton can stop bleeding and sterilize wounds simply, it does not promote wound healing.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the prior art and provides a hemostatic patch which replaces hemostatic cotton used after intravenous injection or blood sampling.

In order to achieve the purpose, the utility model adopts the technical scheme that:

providing a hemostatic plaster, which comprises a transparent plaster cloth layer, a hemostatic layer, a first release paper and a second release paper which are arranged from bottom to top in sequence;

the size of the hemostasis layer is smaller than that of the transparent pasting layer and is arranged on the gluing surface of the transparent pasting layer in the middle, the hemostasis layer comprises a base layer on the lower side, chitosan hemostasis particles and acellular matrix particles, and the chitosan hemostasis particles and the acellular matrix particles are fixed on the upper surface of the base layer;

the first release paper is divided into an inner side part and an outer side part, the inner side part is adhered to the adhesive surface of the transparent adhesive tape layer, and the outer side part extends out of the outer side of the transparent adhesive tape layer;

the second from the type paper adhesion in the gluing face on transparent rubberizing layer and not cover hemostasis layer and inside portion, the second has the bellying from the outside extension of a side edge of type paper, the bellying with the outside portion corresponds the setting.

Further, the base layer is a non-woven fabric layer or a medical spinning cotton layer.

Further preferably, the chitosan hemostatic particles and the acellular matrix particles are fixed on the upper surface of the non-woven fabric or the upper surface of the medical spinning cotton layer through a medical adhesive.

Further, the first release paper is rectangular.

Further, the transparent cloth pasting layer is rectangular.

Further preferably, the shape of the second release paper except the protruding part is rectangular, and the size of the second release paper except the protruding part is the same as that of the transparent adhesive tape layer.

By adopting the technical scheme, compared with the prior art, the utility model has the following technical advantages:

the hemostatic plaster adopts the transparent plaster layer, so that a patient can accurately and intuitively see a bleeding point to perform compression hemostasis conveniently; the chitosan hemostatic particles fixed on the non-woven fabric layer or the medical spinning cotton layer have the effects of quickly stopping bleeding and inhibiting bacteria, and the acellular matrix particles fixed on the non-woven fabric layer or the medical spinning cotton layer have good anti-inflammatory, anti-infection and biocompatibility and can promote the wound to quickly heal.

Drawings

FIG. 1 is an exploded view of the hemostatic patch of the present invention;

wherein the reference numerals are:

the hemostatic cloth comprises a transparent cloth pasting layer 1, a hemostatic layer 2, a first release paper 3, a second release paper 4, a base layer 5, chitosan hemostatic particles 6, acellular matrix particles 7, an inner side part 8, an outer side part 9 and a convex part 10.

Detailed Description

The present invention will be described in detail and specifically with reference to the following examples and drawings so as to provide a better understanding of the utility model, but the following examples do not limit the scope of the utility model.

As shown in fig. 1, the utility model provides a hemostatic patch, which comprises a transparent patch layer 1, a hemostatic layer 2, a first release paper 3 and a second release paper 4, which are sequentially arranged from bottom to top.

The size of the hemostasis layer 2 is smaller than that of the transparent pasting layer 1 and is arranged on the adhesive surface of the transparent pasting layer 1 in the middle, the hemostasis layer 2 comprises a base layer 5 on the lower side, chitosan hemostasis particles 6 and acellular matrix particles 7, and the chitosan hemostasis particles 6 and the acellular matrix particles 7 are fixed on the upper surface of the base layer 5; the base layer 5 is a non-woven fabric layer or a medical spinning cotton layer; the chitosan hemostatic particles 6 and the acellular matrix particles 7 are fixed on the upper surface of the non-woven fabric or the upper surface of the medical spinning cotton layer through medical adhesive.

The first release paper 3 is divided into an inner side part 8 and an outer side part 9, the inner side part 8 is adhered to the adhesive surface of the transparent adhesive cloth layer 1, and the outer side part 9 extends out of the transparent adhesive cloth layer 1;

the second is from the sticky surface of type paper 4 adhesion in transparent rubberizing layer 1 and not cover hemostasis layer 2 and inside portion 8, and the second is from the outside bellying 10 that has of a side edge of type paper 4, and bellying 10 corresponds the setting with outside portion 9.

As a preferable example, the first release paper 3 is rectangular, the transparent adhesive layer 1 is rectangular, and the second release paper 4 except the protruding portion 10 is rectangular and has the same size as the transparent adhesive layer 1.

After pulling out disposable venous transfusion needle or disposable blood taking needle, take off the second from type paper 4 from transparent rubberized fabric layer 1 through the bellying 10 of second type paper 4, because the bellying 10 of second type paper 4 corresponds the setting and not the adhesion with the first outside portion 9 of type paper 3, so make things convenient for the second to take off from type paper 4 from transparent rubberized fabric layer 1. After the second release paper 4 is removed, the hand-held transparent adhesive plaster layer 1 is provided with one end of the first release paper 3, the hemostatic adhesive plaster is pasted on the skin, and the first release paper 3 is removed. The chitosan hemostatic particles fixed on the non-woven fabric layer or the medical spinning cotton layer play a role after being decomposed, and can quickly stop bleeding and inhibit bacteria. In addition, the acellular matrix particles fixed on the non-woven fabric layer or the medical spinning cotton layer have good anti-inflammatory, anti-infection and biocompatibility, and can promote the wound to heal quickly.

While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
