Abstract

The invention discloses a blood drawing protection method, which comprises the steps that a blood drawing guaranteeing device is used for protecting a blood drawing operator, wherein the blood drawing guaranteeing device comprises a guide cone which is provided with a cut, a cover body, a groove, a plurality of bulges and a rubber sleeve; the protection steps comprise the steps that a test tube is inserted from the cut and rotates for an angle, and the force opposite to the rotating angle is applied to the test tube; the processing steps comprises the steps that the guide cone is processed; a double-layer integral mold comprising the conical cut, the guide part and the inner and outer layers of the cut is manufactured; a separation plate is inserted; heating is performed; the separation plate is taken out after mold opening; resin raw materials of the guide part color are placed between the conical cut and the guide part; secondary heating is performed; secondary curing and coloring are performed; the cover body is processed; a colloidal silica body is manufactured as a whole mold; the raw materials are put into the mold for vulcanization; after the mold opening, the bulges are turned out; finish turning is performed. The blood drawing protection method can solve the problems that when a blood drawing needle is inserted into the test tube, the injury can be easily caused on the operator, and the work efficiency is low.

Description

technical field

[0001] The invention relates to the technical field of medical device manufacturing, in particular to a method for protecting an operator from injury when a blood-drawing needle just after blood-drawing is inserted into a test tube during blood-drawing. Background technique

[0002] At present, medical staff generally use blood-drawing needles to insert blood vessels into the patient's arm blood vessels to draw blood for patients. When the amount of blood drawn is sufficient, medical staff need to inject the freshly drawn blood through the blood-drawing needle into the test tube for identification and storage, and draw blood When the needle is inserted into the test tube with a plug, due to the small opening of the test tube, the blood drawing needle is not easy to align, and it takes a certain force to insert the blood drawing needle into the plug of the test tube. If the blood drawing needle is not perpendicular to the plug If the cover surface is inserted,...
