Abstract

The invention provides a skin prick test slope pushing block elastic pin needle. The skin prick test slope pushing block elastic pin needle comprises a needle head, a needle seat, a slope pushing rod and a shell. A transverse hole and a vertical hole which are formed at a certain angle and communicated with each other are formed in the shell. The needle seat is arranged in the vertical hole. The slope pushing rod is arranged in the transverse hole. A slope is arranged at the tail of the needle seat. A dovetail groove is formed in the slope and matched with a protrusion of the slope pushing rod, the protrusion can only slide in the dovetail groove, thus, the slope pushing rod moves in the transverse hole to make the needle seat move in the vertical hole, the tail of the slope pushing rod stretches out of the shell and is provided with a pushing disc, a thick spring is arranged between the pushing disc and the shell, the thick spring can be compressed by pushing the pushing disc, and the thick spring can automatically rebound after the pushing disc is released.

Description

technical field [0001] The invention relates to a needle, in particular to a skin-pricking experiment slope pushing block spring pin needle. Background technique [0002] The existing human skin allergy test mainly obtains the required data through the skin prick test. At present, the skin prick allergen is mainly used in clinical practice-disinfect the patient's bilateral forearms, and drop it on the inside of the forearm every 3-5cm. One drop of allergen drug solution (about 20 kinds), and dripped with histamine positive control and normal saline negative control, puncture the skin vertically with a disposable needle in the center of the drug solution to subcutaneous, observe for 20 minutes, and compare with histamine group and saline group Compare and record the location and size of the wheal. However, for operators, especially beginners, the depth of needle penetration is often uncertain, and the penetration is too shallow to pierce the skin, which may lead to false neg...
