Description

A tourniquet with a tightening buckle

technical field

The utility model belongs to the field of medical technology, in particular to a tourniquet with a tightening buckle.

Background technique

Venipuncture is one of the indispensable technical operations in the process of clinical medical diagnosis and treatment, and it is an important guarantee for various diagnosis and treatment. Venipuncture is required for blood tests, blood transfusion, and surgery. In venipuncture, the irreplaceable necessity of tourniquet is particularly important. There are two types of tourniquets commonly used clinically, one is the traditional rubber tube tourniquet, and the other is the strip-shaped thin silicone tourniquet. The traditional rubber tube is used as a tourniquet because it is economical and flexible. It is good and widely used, but it has the following defects when using it: 1. It needs to be tied live, but because of its high elasticity, it often bounces off automatically, and it has to be tied again, so repeated tying actions seriously affect The emotions of medical staff and patients increase the unnecessary labor intensity of the staff; 2. It is difficult to grasp the force when bandaging. Due to the uneven force, it is impossible to grasp the tightness of the rubber tube on the arm. If the bandage is too loose, the veins cannot It is very good to fill and expose. If the bandage is too tight, there will be deep strangle marks on the arm, which will make the patient feel pain and discomfort. For the improved strip silicone tourniquet, although it solves the defect that the traditional rubber tube is easy to slip when tied and knotted during use, the toughness and elasticity of the silicone tourniquet are not as good as the rubber tube, and there are silicone strip tourniquets. It is easy to form a deep strangulation phenomenon on the patient's skin at the edge, causing the long-term indentation on the patient's skin to be difficult to disappear and the patient's pain and discomfort. In order to improve the success rate of venipuncture in all age groups and overcome the above-mentioned deficiencies in the prior art, a tourniquet with a tightening buckle should be proposed.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model includes a rubber tube 1 and a tightening buckle sleeved on the rubber tube 1, and the tightening buckle includes a housing 2, which is inserted into the housing 2 The pressing piece 3 and the spring 4 installed inside the housing 2 and below the pressing piece 3, the housing 2 is provided with a waist-shaped hole 2-1, the pressing piece 3 includes an upper plate 3-1 and a sleeve The barrel 3-3 is connected to the lower plate 3-2 of the upper plate 3-1. The waist-shaped hole 2-1 is separated by the sleeve 3-3 to form two channels. One end of the rubber tube 1 is provided with a The ball head 6 of the outer diameter of the tube 1, the other end of the rubber tube 1 is provided with an anti-drop ring, and the shell 2 and the pressing member 3 are manually squeezed to make the size of the two channels the largest, respectively. The two ends pass through the two passages, pull the two ends of the rubber tube 1, so that the casing 2 and the pressing part 3 slide on the rubber tube 1 at the same time, until the tourniquet is tightly placed on the patient's wrist or arm, and the shell is released. The body 2 and the pressing part 3, the rubber tube 1 is tightened, the setting of the anti-loosening ring is to prevent the rubber tube 1 from falling off from the tightening buckle due to excessive force when the rubber tube 1 is loosened, And make the rubber tube 1 bounce to the patient's skin, and facilitate the rubber tube 1 to pass through the two passages of the tightening buckle.

In this embodiment, the ball head 6 is integrally formed with the rubber tube 1 to prevent the tightening buckle from being completely separated from the rubber tube 1 when the tourniquet is loosened.

In the present embodiment, the anti-off ring includes an anti-off ring body 5-1 pressed against the end of the rubber tube 1 and a catch 5-2 movably connected to the outside of the anti-off ring body 5-1. 5-2 can be folded along the outer side of the anti-off ring body 5-1. When the end of the anti-off ring of the rubber tube 1 passes through the two passages in sequence, the flap 5-2 is folded until it is close to the anti-off ring On the outside of the body 5-1, when the end of the anti-off ring of the rubber tube 1 passes through the two channels in sequence, the blocking piece 5-2 opens to form an angle with the outside of the anti-off ring body 5-1.

In this embodiment, the inner bottom surface of the housing 2 is provided with a pin shaft 2-2 for the installation of the spring 4, and the installation is reliable.

In this embodiment, the lower plate 3-2 is provided with a through hole having the same inner diameter as the sleeve 3-3, and the spring 4 is located inside the sleeve 3-3.

In this embodiment, the shell 2 and the pressing member 3 are both cylindrical in shape.

In this embodiment, the anti-falling ring body 5-1 and the blocking piece 5-2 are both made of elastic materials.

In actual use, firstly, manually squeeze the housing 2 and the pressing member 3 to make the size of the two passages the largest, and pass the anti-off ring end of the rubber tube 1 through the two passages in sequence. It should be noted that, The baffle 5-2 needs to be folded to be close to the outside of the anti-loosening ring body 5-1. Secondly, pull the two ends of the rubber tube 1 to make the pressing part 3 and the shell 2 slide on the rubber tube 1 at the same time until the tourniquet Put it on the patient's wrist or arm, loosen the housing 2 and the pressing part 3, and the rubber tube 1 is tightened. Simply put, the tourniquet is tied by "pressing, pulling, and releasing". The operation is simple and fast It is convenient and has a good tightening effect, which shortens the time wasted in tying the tourniquet, avoids the cumbersome procedures of repeated tying and knotting for medical staff, saves time and effort, and reduces the labor intensity of medical staff. After the operation is completed, "press and pull" Once the hand is loosened, the tourniquet is loosened, and the anti-loosening ring end of the rubber tube 1 is pulled to remove or the tourniquet is taken off directly after loosening.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical essence of the present utility model still belong to Within the scope of protection of the technical solution of the utility model.
