Droppers for skin prick experiments

Abstract

Disclosed is a dropper for a skin prick test. The dropper comprises a suction tube, a suction bladder and a shell. The shell comprises a cover body and a body, wherein a cover body through hole is formed in the cover body, and a body through hole is formed in the body; the suction bladder is arranged in the shell, and the suction tube stretches out of the body through hole; a press plate and a press column are arranged in the cover body, one end of the press column is connected with the press plate, the other end of the press column stretches out of the cover body through hole, a press spring sleeves the press column, one end of the press spring is connected with the inner wall of the cover body, and the other end of the press spring is connected with the press plate; a plurality of side wall installation through holes which are arranged from top to bottom are formed in the shell, and locating columns and locating springs are arranged in the side wall installation through holes; a side cover plate is arranged on the outer wall of the shell, the lower end of the side cover plate is hinged to the shell, a clamping hook is arranged at the upper end of the side cover plate, and a chuck which is matched with the clamping hook in a clamping connection mode is arranged on the shell; one end of each locating spring is connected with the corresponding locating column, and the other end of each locating spring is connected to the side cover plate. The dropper has the advantages of being high in detection efficiency and safe.

Description

technical field [0001] The invention relates to a dropper, in particular to a dropper used for skin prick experiments. Background technique [0002] The existing human skin allergy test mainly obtains the required data through the skin prick test. At present, the clinical skin prick test mainly uses the skin prick allergen liquid test-disinfecting the patient's bilateral forearms, on the inner side of the forearm A drop of about 20 kinds of allergen drug solution was dripped every 3-5cm, and a positive control of histamine and a negative control of normal saline were added. In the center of the drug solution, a disposable needle was used to puncture the skin vertically to the subcutaneous area, and observed for 20 minutes. The amine group was compared with the saline group, and the location and size of the wheal were recorded. However, for the medical staff, in the process of dripping the original medicinal liquid, there are often too many original medicinal liquids, and th...

Problems solved by technology

However, for the medical staff, in the process of dripping the original medicinal liquid, there are often too many original medicinal liquids, and the medical staff will suck the original medicinal liquid back into the dropper, causing the head of the dropper to touch the patient's skin, and then give the patient When used by one patient, it is easy to cause cross-infection and there are potential safety hazards

Due to the high manufacturing cost of the original drug solution in the experiment, in order to save the original drug solution, the testing medical staff cannot let go during the operation, and it is difficult to drip an appropriate amount of the original drug solution, which makes the entire detection time too long
