Embodiment Construction

[0040] The specific content and implementation of the present invention will be further described below in conjunction with the examples shown in the accompanying drawings.

[0041] A syringe needle with a needle tip in a bionic shape, which is composed of a needle and a bionic structure on the needle tip. The bionic structure can be divided into two types according to the size: macroscopic and microscopic; ; According to the position, it can be divided into two types: the outer wall surface of the needle tip and the beveled surface of the needle tip.

[0042] The size range of the needle-tip bevel bionic structure: in the macroscopic form, the groove depth of the stripe form is 0.01-0.05mm, the groove width is 0.01-0.10mm, and the spacing is 0.02-0.10mm; 0.10mm, spacing 0.02-0.10mm, corrugation depth 0.01-0.05mm, width 0.01-0.10mm, spacing 0.02-0.10mm; in microscopic form, the depth of the part to be etched or sandblasted is 1-10nm, Width 1-10nm, pitch 1-20nm.

Abstract

The invention relates to an injector needle head with a needle point in a bionic form, which is applied to the field of disposable intervention medical appliances in the processes of clinical infusion, puncture, sampling and the like. The injector needle head is characterized in that the needle point outer wall face (3) or the needle point inclined surface (4) of the injector needle head has a macroscopic or microscopic bionic structural form. A bionic structure comprises a strip-shaped structure, a pit-shaped structure and a corrugated structure. The bionic form is added to the needle point of the needle head to reduce the friction force on the needle point in injection and puncture processes, reduce the stimulation effect of the needle point on subcutaneous nerve endings in a puncture process and achieve the effect of relieving pain.

Description

technical field [0001] The invention relates to a syringe needle whose needle tip has a bionic shape. It is used in the field of disposable interventional medical devices for clinical infusion, puncture and sampling. Background technique [0002] Interventional therapy such as drug injection and puncture sampling are the main means of clinical medicine. In the process of injection and puncture, the skin tissue is damaged, and the nerve endings are stimulated to cause pain. The troubles brought by this process to the patient cannot be ignored. In the context of people's pursuit of happiness in life today, effectively reducing injection pain is an effective means to reduce medical fear and improve people's quality of life. Since human beings have to face the problem of injection pain that coexists with the efficacy of the medicine since they are injected with vaccines at the beginning of birth, effectively reducing the injection, puncture pain and body damage of patients is ...
