Embodiment Construction

[0021] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0022] The blood drawing protection method includes using a blood drawing guarantee device to protect the operator, such as Figure 1 to Figure 6 The shown blood drawing guarantee device includes a guide cone 4 that is concave in the middle and is an inverted cone. The rigid resin guide cone guides the blood-drawing needle into the through hole in the middle of the cone, so that the puncture angle of the needle is accurate and will not slip off and injure the operator. One side of the guide cone 4 is longitudinally provided with a guide cone cutout, and a circular cover body 3 for inserting the open end of the test tube 6 is arranged under the guide cone 4, and the guide portion 4-1 of the guide cone 4 is inserted into the cover body 3, and the cover body 3 The lower end of the guide cone guide part 4-1 is provided with a groove 3-1 for inserting ...

Abstract

The invention discloses a blood drawing protection method, which includes using a blood drawing guarantee device to protect the blood draw operator; the blood drawing guarantee device includes a guide cone with a cutout, a cover body, a groove, and a plurality of protrusions. The rubber sleeve, the protection steps include: insert the test tube from the cutout and rotate it at an angle, and then force the test tube to the opposite direction of the rotation angle; processing steps: process the guide cone: make a double layer of inner and outer layers containing the tapered cutout and the guide part and its cutout Integral mould, insert the partition, heat, take out the partition after opening the mold, put the resin material of the color of the guide between the cone and the guide, heat again; secondary curing, coloring; process the cover; make silicone colloid to Make the overall mold; put the raw materials into the mold for vulcanization; after the mold is opened, the protrusions are turned out, and the car is finished. The invention can solve the problems that the operator is easily injured when the blood-drawing needle is inserted into the test tube, 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,...
