Description

Technical Field

[0001] The utility model relates to the technical field of arteriovenous fistula puncture needles, in particular to a protection device for preventing needle stick injuries of arteriovenous fistula puncture needles. Background Technique

[0002] An arteriovenous fistula puncture needle is a medical device mainly used for puncturing arteriovenous fistulas for hemodialysis and other treatments. It is usually made of medical stainless steel or titanium alloy and other materials. The needle tip part is conical or blunt, and can be selected according to the patient's blood vessel conditions and puncture sites. Commonly used models are 17G, 16G, 15G, etc. The puncture needle is recommended in the initial stage of using the arteriovenous fistula because theoretically using a small-sized puncture needle can reduce the irritation and damage to the arteriovenous fistula. The arteriovenous fistula puncture needle mainly consists of a needle tip, a needle tube, a connector, needle wings, a flexible tube, a clip, a protective cap and other structures. Among them, the needle wings are protective wings on both sides of the needle tube, used to stabilize the needle tube during puncture to ensure the safety and accuracy of the puncture process. The protective cap is located at the needle tip part, used to protect the needle tip before puncture to prevent it from being contaminated or damaged.

[0003] In the current prior art, the arteriovenous fistula puncture needle uses a protective cap to protect the needle tip. Only by removing the protective cap can the needle puncture operation be carried out. Since the protective cap and the needle tip are of a split structure, the removed protective cap is easy to be lost after use, making the needle tip without a protective cap easy to stab patients or medical staff, thus causing infections. Therefore, a protection device for preventing needle stick injuries of arteriovenous fistula puncture needles is proposed to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a protection device for preventing needle stick injuries of arteriovenous fistula puncture needles, which has the advantage of preventing the needle tip from stabbing, and solves the problem that the arteriovenous fistula puncture needle uses a protective cap to protect the needle tip. Only by removing the protective cap can the needle puncture operation be carried out. Since the protective cap and the needle tip are of a split structure, the removed protective cap is easy to be lost after use, making the needle tip without a protective cap easy to stab patients or medical staff, thus causing infections.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A protection device for preventing needle stick injuries of arteriovenous fistula puncture needles, including a connecting flexible tube, a connector is arranged on the connecting flexible tube, a puncture needle is arranged on the connector, and a plastic ring is arranged on the connector;

[0006] A transparent shield for protecting the puncture needle is installed on the connecting hose. An arc-shaped clip is clamped on the connecting hose and fixedly connected to the front of the transparent shield. A positioning buckle for clamping the plastic ring is arranged on the arc-shaped clip. The plastic ring is fixedly installed on the outer surface of the joint. Needle wing assemblies for keeping the connecting hose stable are arranged at the top and bottom of the plastic ring.

[0007] Furthermore, one end of the joint penetrates into the interior of the connecting hose and is fixedly connected to the connecting hose. The puncture needle includes a needle tip and a needle tube, which are fixedly connected. One end of the needle tube penetrates into the interior of the joint and is fixedly connected to the joint. A needle cap is sleeved on the joint.

[0008] Furthermore, a groove is formed on the transparent shield. A transparent acrylic support sheet is fixedly installed inside the transparent shield, and a placement groove is formed on the transparent acrylic support sheet.

[0009] Furthermore, the positioning buckle includes a card slot and a positioning ball. The positioning ball is fixedly installed on the back of the plastic ring, and a card slot is formed on the back of the transparent shield. The sizes of the card slot and the positioning ball are adapted to each other.

[0010] Furthermore, the needle wing assembly includes two protective wings and a buckle. The two protective wings are respectively fixedly installed on the outer surface of the plastic ring, and the buckle is fixedly installed on the two protective wings.

[0011] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0012] In the arteriovenous fistula puncture needle anti-needle-stick injury protection device, by providing a transparent shield and an arc-shaped clip, when using the puncture needle, the needle cap sleeved on the puncture needle can be removed, and then the puncture work can be carried out. After the puncture is completed, the transparent shield can be folded along the left side of the plastic ring and sleeved on the puncture needle, so as to protect the puncture needle with the transparent shield and avoid the puncture needle after use from stabbing patients or medical staff. Then, the card slot on the transparent shield is clamped on the positioning ball to limit the transparent shield. Moreover, a buckle is installed on the two protective wings to facilitate fixing the positions of the connecting hose and the puncture needle, ensuring the stability of the needle tube during the puncture process, and enhancing the practicability of the arteriovenous fistula puncture needle anti-needle-stick injury protection device.
