Embodiment Construction

[0024] The present invention is described below in conjunction with accompanying drawing.

[0025] Such as Figure 1 to Figure 5 As shown, the present invention is composed of a needle point 1, a needle tube 2 and a connector 4. The needle point 1, needle tube 2 and the connector 4 are integrally structured. The cross section of the needle tube 2 is circular, and the upper surface is composed of a curve connected by ab a.

[0026] The needle tube 2 viewed from above is centered on the longitudinal axis c-c, and slide rails I3 and II5 are arranged symmetrically on both sides.

[0027] The starting point in slide rail I3 is e, the end point is f, and the line connecting ef forms curve B; the starting point in slide rail II5 is c, the end point is d, and the line connecting cd forms curve B'.

[0028] The mathematical expression of curve A is: y 1 =3.115×10 -5 x 3 -0.04847x 2 +27.36x-4688

[0029] Among them: 350≤x≤410.

[0030] The mathematical expression of curve B is: ...

Abstract

The invention discloses a bionic pain-free syringe needle, and belongs to the technical field of medical instruments. A needle tip, a syringe and a connector are structurally integrated, the cross section of the syringe is circular, a curve A is formed on the upper surface by a connecting line between a and b, the syringe under an overlooking angle takes a longitudinal axis c-c as a center, a sliding rail I and a sliding rail II are symmetrically arranged on two sides of the syringe under the overlooking angle, a starting point in the sliding rail I is e, a terminal point in the sliding rail Iis f, a curve B formed by a connecting line between the e and the f, a starting point in the sliding rail II is c, a terminal point in the sliding rail II is d, and a curve B' is formed by a connecting line between the c and the d. A mathematical expression of the curve A is y1=3.115*10<-5>x<3>-0.04847x<2>+27.36x-4688, wherein 350<=x<=410. The mathematical expression of the curve B is y2=5.407*10<-5>x<3>-0.07635x<2>+38.27x-6025, wherein 340<=x<=400. The bionic pain-free syringe needle simulates curve characters of a bee needle portion of a bumblebee, so that the needle of a syringe is designed and injected into the skin of a human body in a pain-free manner, and the pain of the human body can be relieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a bionic painless syringe needle. Background technique [0002] Subcutaneous injection is a relatively common medical method at present, which uses a syringe to puncture the skin of the human body to directly inject the drug into the body. In the medical injection process, the pain caused by the needle piercing the human body is related to the sensory organs in the human skin. Human skin is composed of three parts: epidermis, dermis and subcutaneous tissue. Pain receptors are located in the epidermis. When the medullary nerve fibers enter the epidermis, they lose the nerve membrane and branch into reticular or small balls, scattered in the intercellular space of the epidermis. Pain points exist and are densely distributed, so the epidermis is particularly sensitive to pain. Receptors depend on four factors: intensity of stimulation, rate of change, time of action, and a...
