The utility model has the advantages that: when the patient needs infusion, the three-dimensional small square on the elastic broadband can partially compress the blood vessel and fill the blood vessel, thereby reducing the discomfort of the surrounding skin; To achieve the purpose of rapid hemostasis; the utility model is not only convenient and practical, but also can reduce the discomfort of patients, and is safe and reliable.

Description

a venous tourniquet

technical field

The utility model relates to a medical device, in particular to a venous tourniquet.

Background technique

A traditional tourniquet is a hollow rubber tube. Nurses usually use a tourniquet to compress blood vessels before intravenous infusion to facilitate needle insertion, but the compression of traditional tourniquets on the skin around the arm often makes patients feel uncomfortable. At the same time, we found that after the infusion, the patient usually panicked because of improper pressure on the needle hole, which caused bleeding at the needle hole.

Contents of the invention

The purpose of the utility model is to overcome the defects in the prior art and provide a venous tourniquet that can quickly stop bleeding, is comfortable and convenient to use, is safe and reliable.

The utility model is achieved in the following way: a venous tourniquet, characterized in that: it comprises a strip-shaped elastic broadband, the two ends of the elastic broadband are respectively fixed end and adjustment end, and the fixed end of the elastic broadband is set There is a ring buckle, the elastic wide band body at the adjustment end is provided with a male and female hasp, and the elastic wide band is provided with a three-dimensional small square that can slide along the elastic wide band.

The small three-dimensional block is provided with a through hole whose width matches the width of the elastic broadband. The through hole is located in the lower half of the small three-dimensional block. slidable connections.

The ring buckle is a rectangular plastic ring buckle or a semicircular plastic ring buckle.

The beneficial effect of the utility model is that: when the patient needs infusion, the three-dimensional small square on the elastic broadband can partially compress the blood vessel and fill the blood vessel, thereby reducing the discomfort of the surrounding skin; after the infusion, the three-dimensional small square can also be used to compress the eye of the needle , to achieve the purpose of rapid hemostasis; the utility model is not only convenient and practical, but also can reduce the discomfort of patients, and is safe and reliable.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a schematic diagram of the side structure of the utility model.

Fig. 3 is a structural schematic diagram of the utility model three-dimensional small cube.

In the figure: 1, elastic wide band; 2, fixed end; 3, adjusting end; 4, ring buckle; 5, male and female buckle; 6, three-dimensional small square; 7, through hole.

Detailed ways

According to Fig. 1-Fig. 3, the utility model comprises the elastic wide band 1 that is elongated, and the two ends of described elastic wide band 1 are fixed end 2, adjustment end 3 respectively, and the fixed end 2 of described elastic wide band 1 is provided with annular buckle 4, the ring buckle 4 is a rectangular plastic buckle or a semicircular plastic buckle. The elastic wide band 1 belt body of the adjustment end 3 is provided with a male and female buckle 5, and when the adjustment end 3 passes through the annular opening 4 during use, the elastic wide band 1 is adjusted and fixed by the male and female buckle 5, so that the elastic wide band 1 forms a ring. The elastic wide band 1 is provided with a small three-dimensional block 6 that can slide along the elastic wide band 1 . Described three-dimensional small square 6 is provided with the through hole 7 that width matches with the width of elastic broadband 1, and described through hole 7 is positioned at the lower half of three-dimensional small square 5, and described elastic wide band 1 passes through through hole 7 to form three-dimensional The slidable connection mode between small square 6 and elastic broadband 1; Because through hole 7 is positioned at the lower half of three-dimensional small square 5, so the lower half thickness of three-dimensional small square 5 is less than the upper half thickness, and the upper half is elastic Obvious bulges are formed on the broadband 1, and when the bulges act on the patient's local blood vessels, they can compress the local blood vessels. At the same time, there is a gap between the elastic broadband 1 and the skin around the compressed local blood vessels, so as to reduce The tourniquet of the utility model has an oppressive feeling to the surrounding skin of the patient.

When the patient does not need to compress the local blood vessels, the utility model can be turned over and used so that the lower half of the small three-dimensional block 6, that is, the thin side, contacts the patient's skin.

When the infusion is finished, move the upper half of the three-dimensional small square 6, that is, the part that is raised relative to the elastic broadband 1, toward the patient's skin, slide the three-dimensional small square 6 of the present utility model and adjust it according to the position of the needle eye, and pass the elastic broadband 1 Adjusting end 3 cooperates with male and female buckle 5 and ring buckle 4 to adjust the length of elastic wide band 1 so that the raised part presses the eye of the needle, thereby reducing the stress area on the eye of the needle, increasing the pressure, and realizing the purpose of rapid hemostasis.
