Description

A puncture-resistant blood collection device

technical field

The utility model relates to a blood sampling device, in particular to a stab-proof blood sampling device.

Background technique

Blood collection needles are widely used clinically. When using blood collection to collect blood from a patient, first insert the venipuncture needle of the blood collection needle into the vein, and pierce the rubber stopper of the vacuum blood collection bottle with the butt-end needle tube, and the blood enters the vacuum blood collection via the passage of the blood collection needle under the vacuum suction of the vacuum blood collection bottle. Blood vessel. As the vacuum degree in the vacuum blood collection tube decreases, the blood collection is terminated when the pressure in the vacuum blood collection tube is approximately equal to the pressure of the blood vessel. For the venipuncture needle end of the blood collection needle, many devices have appeared to cover it to prevent infection caused by stabbing medical staff, but most of the needle tubes at the docking end are only provided with a layer of rubber sleeve to prevent it from being stabbed. Medical personnel, although there is a layer of rubber sleeve on the outside, this can only prevent occasional scratches. If the operation is wrong, the needle is not aligned with the mouth of the blood collection bottle. With a little force, the rubber sleeve will shrink, and the needle will Exposed, causing stab wounds to medical staff, more likely to cause infection, if the patient is a patient of SARS, AIDS, hepatitis B or other infectious diseases, cross-infection will lead to more serious consequences.

Utility model content

The technical problem mainly solved by the utility model is to provide an anti-stab blood collection device which can completely prevent the medical staff from being stabbed by the needle tube connected to the end of the blood collection needle.

In order to solve the above-mentioned technical problems, a technical solution adopted by the utility model is: a stab-proof blood collection device, including a vacuum blood collection bottle and a blood collection needle, the vacuum blood collection bottle includes a bottle body and a bottle cap, and the bottle cap is provided with A threaded through hole, the blood collection needle includes a venipuncture needle and a docking needle, a hose is connected between the venipuncture needle and the docking needle, the outside of the docking needle is wrapped with a rubber sleeve, and the end of the rubber sleeve The head is fixed with an anti-stab head, and the periphery of the anti-stab head is provided with external threads. A stopper, the stopper penetrates to the inside of the anti-stab head, the stopper is provided with a strip-shaped hole, one end of the stopper is connected to a reset element, and the other end of the reset element is connected to the inside of the anti-stab head.

Preferably, when no external force acts on the stopper, the strip-shaped hole on the stopper does not communicate with the rubber sleeve.

Preferably, when an external force acts on the stopper, the reset element is in a compressed state, the position of the strip-shaped hole communicates with the rubber sleeve, and the docking pin can pass through the strip-shaped hole.

Preferably, the reset element is a spring.

Preferably, a rubber stopper is provided inside the bottle cap, and the rubber stopper seals the bottle body.

Preferably, the bottle body is made of transparent material.

Beneficial effects: the utility model adds an anti-stab head at the end of the rubber sleeve of the blood collection needle. If the stopper is not pressed, the docking needle cannot cause stab wounds to the medical staff, which fully guarantees the risk of medical staff being infected , The utility model has reasonable structure and is easy to operate.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, a stab-proof blood collection device includes a vacuum blood collection bottle and a blood collection needle, the vacuum blood collection bottle includes a bottle body 11 and a bottle cap 12, and the bottle body 11 is made of a transparent material for easy observation In the case of blood collection, the bottle cap 12 is provided with a rubber stopper, which seals the bottle body 11 and keeps the inside of the bottle body 11 in a vacuum state. The bottle cap 12 is provided with a threaded through hole, and the blood sample The needles include a venipuncture needle 21 and a docking needle 22, a hose is connected between the venipuncture needle 21 and the docking needle 22, and the outside of the docking needle 22 is wrapped with a rubber sleeve 23, and the end of the rubber sleeve 23 is The head is fixed with an anti-stab head 24, which is used to prevent accidental stab wounds. The periphery of the anti-stab head 24 is provided with external threads, and the external threads on the anti-stab head 24 and the threaded through holes on the bottle cap 12 threaded connection.

As shown in Figure 3, the anti-stab head 24 is provided with a block 25, the block 25 penetrates to the inside of the anti-stab head 24, the block 25 is provided with a strip hole 251, the block 25 One end is connected with a spring 252, and the other end of the spring is connected to the inside of the anti-stab head. When no external force acts on the block 25, the bar-shaped hole 251 on the block 25 is not in contact with the rubber sleeve 23. In communication, under the action of an external force, the spring 252 is in a compressed state, and the position of the strip-shaped hole 251 communicates with the rubber sleeve 23 .
