Description

Medical dressing

Technical field

This technical solution belongs to the technical field of medical auxiliary devices, specifically a medical dressing.

Background technique

Venipuncture is suitable for intravenous infusion, intravenous injection and blood drawing. After venipuncture, the patient presses the needle for insufficient time or the position is inaccurate, resulting in ineffective local hemostasis, resulting in bleeding, oozing, subcutaneous congestion and ecchymosis, which not only damages the blood vessels, but also causes ecchymosis. It also makes the choice of next puncture more difficult.

In clinical treatment, taking intravenous infusion as an example, a medical patch (also called an infusion patch) is attached to the puncture site of the skin after puncture to fix the puncture needle. When the infusion is completed, pull out the puncture needle and directly press the needle hole with a medical dressing. Since the medical patch covers the needle eye when the puncture needle is fixed, after the needle is pulled out, the medical patch also covers the needle eye and can be easily used to press on the needle eye to stop bleeding. Different from the past use of cotton swabs and other methods to directly press on the needle hole, when using medical compresses, the following problems often occur after the needle is pulled out:

1. When pressing, the medical patch covers the puncture site. For ordinary people, it blocks the eye of the needle, causing the pressing position of the human hand to deviate from the eye of the needle, resulting in poor hemostasis.

2. If the subcutaneous fat is thick, the fat will affect the effect of external force on the needle eye, resulting in poor hemostatic effect.

Analyze the reasons:

1. There are usually two needle holes in venipuncture. One is the needle hole that passes through the skin, which is visible; the other is the needle hole that goes into the skin and then moves the needle along the blood vessel for a while and then enters the blood vessel and passes through the blood vessel wall. Out of sight. There is a certain distance between the two needle holes. If you press the needle hole in the skin but not the needle hole in the blood vessel, the blood will still flow into the subcutaneous from the needle hole in the blood vessel wall. If you only press the needle hole in the blood vessel but not the skin needle hole, the blood will be affected when passing through the skin. Damaged capillaries will still have blood flowing out.

2. The area of medical application is not large, and it cannot form enough pressure on the needle hole, so that the fat has a certain "buffering" effect on the smaller pressure, resulting in poor hemostatic effect.

In addition, there are also problems when using medical dressings with intravenous indwelling needles: medical dressings are adhesive, while the needle eye of the intravenous indwelling needle has a film directly attached to the skin. When the medical dressing is removed, it is easy to remove it. The film used for the intravenous indwelling needle is also taken off.

Contents of the invention

In order to solve the problems existing in the prior art, the present utility model proposes a medical patch, which can more conveniently and effectively stop the bleeding of the venipuncture needle after the needle is pulled out, and can replace the existing infusion patch, as follows.

A medical dressing, including a cloth layer, and an absorbent pad connected to the bottom surface of the cloth layer, characterized in that the absorbent pad is located in the center of the cloth layer;

There is an auxiliary mark on the top surface of the fabric layer showing the direction of the blood vessels. Below the cloth layer where the auxiliary mark is located is an absorbent pad; the direction of the blood vessels indicated by the auxiliary mark is consistent with the width direction of the cloth layer;

Assume that the two ends of the length direction of the cloth layer are the front end and the rear end respectively, and the two ends of the width direction of the cloth layer are the upper end and the lower end respectively; the length of the cloth layer is not less than 20cm (not less than the arm circumference of an ordinary adult's arm);

It is divided into three sections connected in sequence along the width direction of the cloth layer. The material of the upper section of the cloth layer and the lower section of the cloth layer is elastic; the material of the middle section of the cloth layer is inelastic, and the width of the absorbent pad is smaller than the width of the middle section of the cloth layer;

Only the bottom surface of the upper section and the lower section of the cloth layer has an adhesive layer; the front and rear ends of the middle section of the cloth layer have connecting structures for mutual connection respectively;

The length of the main body of the water-absorbent pad is smaller than the width of the main body.

The middle section of the non-elastic cloth layer mainly plays a pressing role, while the upper and lower sections of the elastic cloth layer are mainly used to seal the skin part where the needle hole is to isolate it from the external environment.

A further improvement is that the shape of the main body of the water-absorbent pad is an ellipse, and there are extensions along the straight line where the short axis is located on both sides of the ellipse's short axis.

When in use, the two extended parts of the absorbent pad are below the middle section of the cloth layer. They have a large contact area with the middle section of the cloth layer. When the two ends of the middle section of the cloth layer are tightened, the middle section of the cloth layer has a greater impact on the two extended parts. , and then affects the middle part of the absorbent pad (the part that presses on the needle holes and blood vessels), improving the pressure exerted on the needle holes and blood vessels.

Further improvement is as follows: the auxiliary mark of the direction of the blood vessel is a "cross" mark, the center point of the "cross" mark coincides with the center of the absorbent pad; the straight line corresponding to the width direction of the cloth layer in the "cross" mark extends to the cloth layer. The upper and lower ends of the layer. This mark helps align the direction of the blood vessels when applying the applicator. The "cross" mark may be a "cross" pattern printed on the top surface of the cloth layer.

The first improvement is: the connection structure between the front and rear ends of the middle section of the cloth layer is: there is an adhesive layer on the bottom surface of the front end of the middle section of the cloth layer; there is a matte surface of Velcro on the top surface of the front end of the middle section of the cloth layer. There is a hook surface of Velcro on the bottom surface of the rear end of the middle section of the layer.

The second improvement is: the connection structure between the front and rear ends of the middle section of the cloth layer is: there is an adhesive layer on the bottom surface of the front end of the middle section of the cloth layer, and there is an adhesive layer on the bottom surface of the rear end of the middle section of the cloth layer.

Both of these improvements can help improve practical convenience and reliability. In the first improved use, first bond the adhesive layer at the front end to the skin, then wrap the back end around the arm, and then bond it with the Velcro at the front end. In the second improved use, first bond the adhesive layer of the front end to the skin, then wrap the back end around the arm, and then bond it to the top surface of the front end.

In the unused state, there is an isolation film on the bottom of the cloth layer, a water-absorbent pad is between the isolation film and the cloth layer, and the isolation film is attached to the surface of the adhesive layer. Isolation films help protect various parts of the application during packaging, storage and transportation, especially to prevent the adhesive layer from sticking to other items.

During use, for the most common arm venipuncture, the blood vessels are basically along the length of the arm. For medical staff, they are familiar with the direction of blood vessels. Combined with the auxiliary markings of the blood vessel direction, they can more accurately align the central line of the absorbent patch with the blood vessels, so that the main body of the absorbent patch can be pressed against the inner and outer needle holes. After the medical staff has applied the patch, if the patient wants to press the absorbent patch inside the patch, it will also help to accurately press to the needle hole.

Examples of how to use this applicator are as follows:

For example, after removing the needle for venous blood collection: Step 1) Align the direction of the blood vessel direction indicated by the auxiliary mark on the application with the width of the cloth layer, and press the absorbent pad at the needle eye. Step 2) After wrapping the cloth layer around the arm along its length, tightly connect the front and back ends of the middle section of the cloth layer so that the absorbent pad presses against the eye of the needle. Step 3) Bond the elasticity of the upper and lower sections of the cloth layer to the skin.

Since the middle section of the cloth layer is made of non-elastic material, the absorbent pad does not rebound when it exerts pressure on the needle eye after tightening. Moreover, during the tightening operation, the negative impact of the subcutaneous fat layer on the pressure test of the absorbent pad can be reduced.

If it is intravenous infusion, after venipuncture, follow the above steps 1) to 3) to put the patch on. However, in step 2), the middle section of the fabric layer does not need to be pulled too tightly. When removing the needle after the infusion, first uncover more than half of the cloth layer along the length direction, then remove the needle, and then follow the above steps 1) to 3) to put the dressing in place.

If it is used with an intravenous indwelling needle, follow the above steps 1) to 3) to put the patch on after venipuncture. However, in step 2), the middle section of the fabric layer does not need to be pulled too tightly. In step 1), pay attention to the adhesive on the bottom surface of the upper and lower sections of the cloth layer to avoid the film that matches the intravenous indwelling needle. In this application, since there is no adhesive layer in the middle of the fabric layer, the middle part of the fabric layer is wide enough to cover the film without sticking to the film.

In actual production, from the perspective of production convenience, the overall material of the cloth layer is elastic (can be elastic cloth); a non-elastic cloth is connected to the bottom or top surface of the cloth layer to form the middle section of the cloth layer.

When the production scale is large, the middle section of the cloth layer can be a woven non-elastic medical bandage cloth. The upper section of the cloth layer and the lower section of the cloth layer are respectively bonded to the upper and lower sides of the middle section of the cloth layer with medical silicone tapes. Medical silicone has adhesion to the skin, which can better seal the skin at the eye of the needle and isolate it from the external environment.

The medical patch can better solve the problems existing in the existing technology, is convenient to use, and achieves good results after application.
