Description

Protective sleeve for intravenous indwelling needle

technical field

The utility model relates to the technical field of medical auxiliary appliances, in particular to a protective cover for intravenous indwelling needles.

Background technique

The intravenous indwelling needle, its main components include a soft catheter that can be indwelled in the blood vessel and a stainless steel puncture guide core. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy. As a replacement product of scalp needles, intravenous indwelling needles have been widely used in recent years due to their advantages such as simple operation, long indwelling time, less pain caused by repeated venipuncture, less irritation to blood vessels, protection of blood vessels, and convenient clinical medication. It is used clinically and becomes an important tool for clinical infusion medicine.

At present, the method used to fix the venous indwelling needle in the hospital is mainly to use a transparent venous indwelling needle film, which is pasted on the surface of the skin through an adhesive layer and covers the surface of the indwelling needle as a whole. However, this fixing method has the following disadvantages: 1. The adhesive layer of the film is in close contact with the skin, which affects the air permeability of the skin, and easily causes skin allergies such as skin redness and itching, causing discomfort to the patient; 2. The film often curls up 3. Since the film is transparent, you can still see the exposed part of the intravenous indwelling needle, which will cause fear in children, and children will go to the place because of their active nature. Tear the film, and the infusion tee of the intravenous indwelling needle is still exposed outside when not infused, so patients are easy to pull and touch the infusion tee in daily care, especially children, they will deliberately pull the infusion tee, thus Dislodges and dislodges the IV catheter.

Utility model content

In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

A protective cover for intravenous indwelling needles, characterized in that it includes an elastic protective cover body and a transparent hard fixed cover, the protective cover body is in a grid-shaped hollow structure, and the middle part of the protective cover body is provided with an opening. Both the upper and lower ends of the fixed cover and the opening are provided with adhesive layers, the upper part of the inner side of the fixed cover is provided with a first sponge pad, and the side and lower part of the first sponge pad is provided with a second sponge pad. One side of the inner side is provided with a third sponge pad, the first sponge pad, the second sponge pad and the third sponge pad are distributed in a triangle, the side of the protective cover body is provided with an elastic band with the same length, and the protective cover The body and the upper and lower ends of the elastic band are provided with Velcro glued to each other.

The general idea of the utility model is: through the fixed cover and the adhesive layer at the upper and lower ends of the opening are bonded to each other, the first sponge pad covers and compresses the puncture needle part of the venous indwelling needle, the second sponge pad and the third sponge pad cover and compress The infusion tube part of the intravenous indwelling needle, so that the fixed cover maintains the fixed position of the intravenous indwelling needle, and the infusion tee of the intravenous indwelling needle is placed outside the fixed cover, which is convenient for medical staff to perform infusion operations. , so that the venous indwelling needle is covered under the elastic band as a whole, which effectively avoids pulling the infusion tee and causing the venous indwelling needle to shift and fall off, and at the same time reduces the fear of children.

In addition, the utility model also provides the following subsidiary technical solutions:

Further, a silicone waterproof layer is provided around the inner side of the opening. The protective cover is made waterproof to avoid infection caused by moisture entering the puncture area in the daily life of the patient. At the same time, the silicone is close to the human skin to improve the comfort of the patient.

Further, the outer surface of the elastic band is provided with a waterproof layer. Further improve the waterproofness of the protective case.

Further, the fixed cover is arc-shaped, which cannot be bent in the axial direction but can be bent in the radial direction. The arc-shaped fixed cover can be closer to the patient's arm, so that the fixed cover can fix the intravenous indwelling needle more firmly.

Further, the arc of the fixed cover is 150°-179°.

Further, the lower part of the elastic band is provided with a longitudinal zipper, and the distance between the zipper and the connection between the protective sheath body and the elastic band is 5cm-8cm. When you need to infuse or observe the condition of the intravenous indwelling needle, you only need to unzip the zipper and open the elastic band without disassembling the elastic band, which is convenient for medical staff to operate.

Further, the length of the first sponge pad is 3cm-6cm, the width is 2.5cm-4.5cm, and the thickness is 3-10mm. It can ensure that the puncture needle part of the intravenous indwelling needle is completely covered by the first sponge pad to prevent it from being polluted.

Compared with the prior art, the beneficial effects of the utility model are:

1. The utility model is simple in structure, easy to operate, can effectively fix the venous indwelling needle, prevent it from shifting or falling off, can completely replace the indwelling needle film, and avoid the occurrence of allergies in patients;

2. In the utility model, the intravenous indwelling needle is completely covered under the elastic band, so that the child patients cannot see the indwelling needle, which can reduce their sense of fear;

3. The utility model adopts a grid-shaped protective cover body, which can improve air permeability. At the same time, the fixed cover is made of transparent material, which is convenient for observing the situation of the intravenous indwelling needle, and the elastic band is equipped with a zipper, which is convenient for medical staff to perform infusion and observation , easy to operate, and can be widely promoted in the industry.

detailed description

The utility model is described below in conjunction with the accompanying drawings and embodiments, and the following embodiments are explained with the best effect of the utility model, but these embodiments are not limitations of the utility model.

Example 1:

As shown in Figures 1-3, a protective cover for intravenous indwelling needles includes an elastic protective cover body 1 and a transparent hard fixed cover 2. The protective cover body 1 has a grid-shaped hollow structure; the middle part of the protective cover body 1 An opening 3 is provided, and a silica gel waterproof layer 7 is provided around the inner side of the opening 3; an adhesive layer 5 is provided on the upper and lower ends of the fixed cover 2 and the opening 3; A second sponge pad 202 is provided under the side of the sponge pad 201, a third sponge pad 203 is provided on one side of the inner side of the fixed cover 2, and the first sponge pad 201, the second sponge pad 202 and the third sponge pad 203 are distributed in a triangle The side of the protective cover body 1 is provided with an elastic band 4 with the same length, and the outer surface of the elastic band 4 is provided with a waterproof layer (not shown in the figure), and the lower part of the elastic band 4 is provided with a longitudinal zipper 8, and the zipper 8 is connected to the protective cover body 1 and the elastic band The distance between the joints of 4 is 6cm; the upper and lower ends of the protective cover body 1 and the elastic band 4 are provided with Velcro 6 bonded to each other.
