Description

An anti-stab protection device for puncture needles

technical field

The utility model relates to medical equipment, in particular to an anti-stab protection device for puncture needles.

Background technique

The venous indwelling needle is a medical device used for intravenous infusion therapy. The venous indwelling needle is easy to operate and is suitable for puncture in any part. It also reduces the pain of repeated puncture for patients and the workload of nurses. Nurses welcome. In clinical use, the puncture needle guides the cannula of the indwelling needle into the vein of the human body. After seeing the return of blood, confirm the success of the venipuncture, withdraw the puncture needle, and only keep the soft indwelling needle cannula in the vein. The medicinal solution is injected into the human body through the cannula of the indwelling needle. The cannula of the indwelling needle is made of soft and elastic material, which can be used within the safe indwelling time of the human vein, and bends synchronously with the vein with the movement of the human body, so that the injection site can still move freely without the risk of puncturing the vein Yu. This prevents frequent punctures from causing pain to the patient.

However, it is found in clinical operations that when the medical staff pulls out the puncture needle of the intravenous indwelling needle, the needle point of the puncture needle may stab the medical staff. The cause of this accident is mainly due to a common but often overlooked instinctive reaction. Take the common action of pulling out the cork in life as an example: when a person holds the bottle body with one hand and keeps still, the other hand exerts force to remove the cork. When pulling out the cork, the hand holding the cork will stop quickly and retract in the opposite direction during the swing away from the bottle body. An instinctive reaction to hard objects is basically difficult to overcome. Like pulling out the cork, after the medical staff pulls out the puncture steel needle forcefully, the hand holding the steel needle will also have a retraction process, and at this time the needle just corresponds to the other hand of the medical staff. Once the retraction action is too large, the puncture steel needle sticking with the patient's blood may accidentally injure the medical staff, which in turn may cause the medical staff to be infected by the bacteria carried in the patient's blood. In addition, when disposing of discarded puncture needles, it may also cause staff to be stabbed, making it difficult for special treatment of medical waste, thus causing serious social security risks.

Contents of the invention

In order to solve the above-mentioned existing problems, the utility model provides an anti-stab protection device for a puncture needle.

The technical scheme of the utility model is achieved in that:

An anti-stab protection device for a puncture needle, comprising a puncture needle base, the puncture needle base is tightly connected with the puncture needle, and a protective cover is provided at the connecting end of the puncture needle base and the puncture needle, and the protective cover is in the shape of a spring.

The spring-like boot has more coils at the head than at the middle and bottom.

The length of the spring-shaped protective cover in an uncompressed state is greater than the length of the part of the puncture needle extending out of the puncture needle seat.

The diameter of the spring-shaped protective cover is smaller than that of the puncture needle seat.

The diameter of the spring-shaped protective cover is smaller than the diameter of the insertion end of the indwelling needle hub.

The utility model solves the problem that once the retraction action of the current puncture needle is too large during use, the puncture steel needle sticking with the patient's blood will accidentally injure the medical staff, and further cause the medical staff to be infected by the bacteria carried in the patient's blood. The novel structure is simple and practical, suitable for straight and Y-shaped indwelling needles, and has great market promotion value.

detailed description

Embodiment 1, as shown in Figure 1, the utility model includes a puncture needle base, the puncture needle base is tightly connected with the puncture needle, a protective cover is provided at the connecting end of the puncture needle base and the puncture needle, and the protective cover is spring-shaped , the number of coils at the head of the spring-shaped protective cover is greater than that at the middle and bottom, the length of the spring-shaped protective cover in an uncompressed state is greater than the length of the puncture needle extending out of the puncture needle seat, and the diameter of the spring-shaped protective cover is less than The puncture needle hub, the diameter of the spring-shaped protective cover is smaller than the diameter of the insertion end of the indwelling needle hub.

As shown in Fig. 2 and Fig. 5, after the puncture needle punctures the blood vessel, when the utility model pulls out the puncture needle, the spring will reset along with the backward movement of the puncture needle seat. Prevent stab wounds.

Embodiment 2, as shown in Figure 3, the utility model includes a puncture needle base, the puncture needle base is tightly connected with the puncture needle, a protective cover is provided at the connection end of the puncture needle base and the puncture needle, and the protective cover is a folded tubular , the material of the protective cover is a highly elastic material, the diameter of the protective cover is smaller than the puncture needle hub, the diameter of the protective cover is smaller than the diameter of the insertion end of the indwelling needle hub, and the length of the protective cover in an uncompressed state is greater than the length of the puncture needle extending out of the puncture needle hub.

As shown in Figure 4 and Figure 6, after the puncture needle punctures the blood vessel, when the utility model pulls out the puncture needle, the telescopic tube will reset with the backward movement of the puncture needle seat, until it is fully reset, the telescopic tube will completely wrap the puncture needle , Effectively prevent stab wounds.
