Single-use anti-acupuncture insulin injection pen and anti-acupuncture method

Abstract

The invention discloses a single-use anti-acupuncture insulin injection pen, which comprises a casing (10), a needle seat (20), an injection needle (21), a needle tip protection sleeve (30), an elastic member (1), and a sliding sleeve (50) and a retaining claw (60), wherein the sliding sleeve (50) sleeves the needle seat (20), and the retaining claw (60) is fixedly connected to the needle seat (20); a claw portion (62) at least partially is located outside the sliding sleeve (50) and flared outward; when the needle tip protection sleeve (30) is pressed against the needle seat (20), the slidingsleeve (50) is pressed to be deformed and the needle tip protection sleeve (30) is hooked with the sliding sleeve (50); when the pressure is lost, the elastic member (1) pushes the needle tip protection sleeve (30) to move, and the sliding sleeve (50) is disengaged; and the retaining claw (60) is restored to its original shape and the sliding sleeve (50) and the needle tip protection sleeve (30)are prevented from moving downward. The injection needle can be self-locked reliably and safer after use.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable acupuncture-proof insulin injection pen needle and a needle-proof method. Background technique [0002] Diabetes is a common chronic disease. As the disease progresses, patients need to inject insulin to achieve the goal of lowering blood sugar. Needles for insulin injection pens are rapidly being widely used in the field of diabetes treatment. Compared with traditional needle injections, insulin pens usually have the following advantages: 1. Eliminate the tediousness of needle injections, avoid embarrassment in public places, and are more convenient for patients with poor eyesight. 2. The insulin dose is more precise, and the insulin dose can be adjusted by 1 unit. Syringes are usually as accurate as 2 units. 3. Basically painless, the needle is thinner than that of a special insulin syringe, and some patients feel that there is basically no pain after using it. H...

Problems solved by technology

However, most of the needles were not removed from the injection pens in time and were discarded in covered hard-shell containers, and these irregular operations greatly increased the risk of needle-stick injuries for patients, their families, and even sanitation workers

[0003] The frequent use of needles for insulin injection pens is the most likely to cause secondary injuries to medical staff. At present, there are many types of needles for disposable needle-proof insulin injection pens in the market, but each has its own problems, such as complex structure and high production cost; complex structure and corresponding It leads to large volume and inconvenient use; in addition, after using the current insulin injection pen needle, people cannot clearly know whether it has been used. To determine whether it has been used, it needs to be determined by pressing the needle tip protective cover. If the pen needle has not been used or When the self-locking mechanism fails, the needle tip is easy to hurt people, and there is a greater safety risk
