Description

A kind of medical indwelling needle eye patch

technical field

The present application relates to the technical field of medical devices, and more particularly, to an eye patch for medical indwelling needles.

Background technique

The venous indwelling needle includes a soft catheter/cannula that can be indwelled in the blood vessel, and a stainless steel puncture needle guide needle core. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter is fully inserted into the blood vessel, the needle is withdrawn. Core, only the flexible catheter is left in the blood vessel for infusion therapy.

Intravenous indwelling needles are widely used in clinical infusion and blood transfusion due to their simple operation and convenient use, which can reduce the pain of repeated puncture of patients. Since the venous indwelling needle is to indwell the catheter in the blood vessel, compared with the traditional steel needle, the puncture needle of the venous indwelling needle is larger. In the prior art, cotton swabs are usually used to press the needle eye position after the indwelling needle is pulled out to stop bleeding. In clinical practice, due to insufficient pressing time and incorrect pressing method, subcutaneous bleeding often occurs after needle extraction, which brings certain pain to patients.

Therefore, there is an urgent need for a medical indwelling needle eye patch, which can be firmly and reliably fixed, can reduce the local pressing time after the needle is pulled out, and reduce the subcutaneous bleeding at the puncture site after the needle is pulled out.

Utility model content

In order to solve the above technical problems, the present application provides a medical indwelling needle eye patch, which is firmly and reliably fixed, can reduce the local pressing time after the needle is pulled out, and reduce the subcutaneous bleeding at the puncture site after the needle is pulled out.

The technical solutions provided by this application are as follows:

A medical indwelling needle eye patch, characterized in that it comprises,

an adhesive bandage on the lower surface;

a waterproof layer fixed with the partial adhesion of the bandage;

an adhesive layer arranged on the side of the waterproof layer away from the bandage;

a liquid-absorbing layer adhered and fixed with the middle position of the adhesive layer;

A protective film covering the surface of the liquid absorbing layer and adhering to the adhesive layer around it.

Preferably, the bandage is made of elastic material.

Preferably, the waterproof layer is medical waterproof non-woven fabric, polyethylene impermeable film or polyurethane film.

Preferably, the adhesive layer is a medical pressure-sensitive adhesive layer.

Preferably, the waterproof layer and the adhesive layer are integrally formed.

Preferably, the liquid-absorbing layer is a non-woven water-absorbing pad, a polymer liquid-absorbing material or a biological liquid-absorbing material.

The embodiments of the present utility model are written in a progressive manner.

As shown in FIG. 1 , an embodiment of the present utility model provides a medical indwelling needle eye patch, including a bandage 1 with adhesiveness on the lower surface; a waterproof layer 2 that is partially adhered and fixed with the bandage 1; The adhesive layer 3 on one side of the 1; the liquid absorbing layer 4 in the middle position with the adhesive layer 3;

In the prior art, cotton swabs are usually used to press and stop bleeding at the position of the indwelling needle after the needle is pulled out. However, in clinical practice, due to insufficient pressing time and incorrect pressing method, subcutaneous bleeding often occurs after the needle is pulled out. The patient suffers a certain amount of pain.

It should be noted that the "partial adhesion and fixation of the waterproof layer and the bandage" in the present invention means that the size of the waterproof layer 2 is smaller than the size of the bandage 1, and the bandage 1 around the waterproof layer 2 can be connected with the patient's skin. Adhesion fixation provides a sterile and closed environment for the damaged part of the skin after the indwelling needle is removed, and reduces the hidden danger of local infection caused by the exposure of the wound.

The medical indwelling needle eye patch provided by the present invention is firstly provided with a bandage 1, a waterproof layer 2 and a liquid-absorbing layer 4, wherein the lower surface of the bandage 1 is sticky, and the waterproof layer 2 and the bandage 1 are partially adhered and fixed to prevent the patient from suffering. The blood at the needle eye seeps out from the bandage 1, the waterproof layer 2 is provided with an adhesive layer 3 on the side away from the bandage 1, the liquid-absorbing layer 4 is fixed at the middle position of the adhesive layer 3, and the protective film 5 is covered on the liquid-absorbing layer 4. The surface of the protective film 5 is adhered to the adhesive layer 3 around the protective film 5. When the indwelling needle needs to be pulled out, the indwelling needle is torn off to fix it, and the protective film 5 is torn off. Press the bandage 1 on the outside of the water-absorbing layer with the thumb of the right hand, pull out the indwelling needle with the left hand, smooth the waterproof layer 2, make the waterproof layer 2 and the skin around the patient flat, wrap the bandage 1 around the affected area under pressure, pass the bandage 1 time The adhesiveness of the surface fixes the bandage 1 , and local hemostasis is performed on the affected area through the pressure action of the bandage 1 , thereby reducing the time for the patient or nurse to acupressure to stop the bleeding.

It can be seen that, compared with the prior art, the medical indwelling needle eye patch in the embodiment of the present invention is firmly and reliably fixed, and can reduce the local pressing time after the needle is pulled out, and reduce the subcutaneous bleeding at the puncture site after the needle is pulled out.

As a more preferred embodiment, the adhesive layer 3 in the embodiment of the present invention is a medical pressure-sensitive adhesive layer. The medical pressure-sensitive adhesive layer has good air permeability, does not affect the normal ventilation of the skin during use, and does not affect the normal suction function of the skin during use. It does not hurt the skin when exposed, its sensitization is low, and no adverse reactions occur.

Preferably, the waterproof layer 2 in the embodiment of the present invention is a medical waterproof non-woven fabric, a polyethylene impermeable film or a polyurethane film.

More preferably, the medical pressure-sensitive adhesive layer in the embodiment of the present invention is a medical hot-melt pressure-sensitive adhesive layer, and is integrally formed with a waterproof non-woven fabric.

Preferably, the protective film 5 in the embodiment of the present invention is a release-type release paper.

As a more preferred embodiment, the bandage 1 in the embodiment of the present invention has a rectangular structure.

As a more preferred implementation of waterproofing, the bandage 1 in the embodiment of the present invention is a self-adhesive medical elastic bandage; the waterproof layer 2 is a medical waterproof non-woven fabric; and the adhesive layer is a pressure-sensitive adhesive layer. The medical indwelling needle eye patch in the embodiment of the utility model has a simple structure and simple operation, and adopts a self-adhesive medical elastic bandage, a medical waterproof non-woven fabric and a pressure-sensitive adhesive layer, which is non-toxic, safe, low in cost, and easier in clinical practice. promotion.
