Problems solved by technology

In this disposable medical injection needle, the needle tube is mostly made of stainless steel, and the needle seat is made of petroleum plastic. After use, it is mainly disposed of through incineration, which will generate a large amount of greenhouse gas and discharge it into the air, causing the greenhouse effect and even releasing nitrogen compounds. , sulfide and other toxic gases, seriously polluting the environment; in addition, the needle material is relatively hard, which is easy to damage the patient's skin

Embodiment Construction

[0026] Such as figure 1 As shown, this biodegradable disposable medical injection needle includes a needle tube 1 and a needle base 2, the lower end of the needle tube 1 is connected to the needle base 2, the upper end of the needle tube 1 has a needle point 3, the cavity 4 of the needle tube 1 and the cavity 5 of the needle base 2 connected. In this embodiment, the upper end of the needle tube 1 has an inclined end face 6 (that is, the end face 6 is a plane, and the angle α between the end face 6 and the center line of the needle tube 1 is greater than 0° and less than 90° (for example, 40°)) The point where the inclined end surface 6 intersects with the outer surface of the needle tube 1 forms the needle tip 3 . The needle tube 1 is made of polylactic acid fiber. In this embodiment, the needle tube 1 is formed by melting and extruding polylactic acid fiber pellets through an extruder, forming and cold stretching through a tubular drawing die. The needle holder 2 is made of...

Abstract

The invention provides a biodegradable disposable medical syringe needle which comprises a needle tube and a needle base, wherein the lower end of the needle tube is connected with the needle base, the upper end of the needle tube is provided with a needle tip, and a cavity of the needle tube is communicated with a cavity of the needle base. The biodegradable disposable medical syringe needle is characterized in that the needle tube is made of polylactic acid fiber, and the needle base is made of polylactic resins. The invention further provides a manufacturing method of the biodegradable disposable medical syringe needle. The disposable medical syringe needle is totally made of polylactic acid materials, can be totally degraded into water and carbon dioxide after being destroyed and disinfected after use in an ecological environment, cannot pollute the environment, reduces environment pollution caused by medical rubbish and reduces the damage of the syringe needle capable of infecting germs and viruses in public places. Further, the disposable medical syringe needle uses soft materials, the surface of the needle tip is smooth and has no sharp edges, and the damage to the skin of a patient is reduced.

Description

technical field [0001] The invention relates to medical equipment, in particular to a biodegradable disposable medical injection needle and a manufacturing method of the disposable medical injection needle. Background technique [0002] Usually, when a patient is treated with injection, the medicinal liquid is injected into the blood vessel of the patient through an injection needle. Currently commonly used disposable medical injection needles include a needle tube and a needle base. The lower end of the needle tube is connected to the needle base, and the upper end of the needle tube has a needle point. In this disposable medical injection needle, the needle tube is mostly made of stainless steel, and the needle seat is made of petroleum plastic. After use, it is mainly disposed of through incineration, which will generate a large amount of greenhouse gas and discharge it into the air, causing the greenhouse effect and even releasing nitrogen compounds. , sulfide and other...
