Description

technical field

[0001] The invention relates to the technical field of medical device manufacturing, in particular to a device for protecting an operator when a blood-drawing needle that has just drawn blood is inserted into a test tube. 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, the blood-drawing needle is eas...

Embodiment Construction

[0015] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0016] Such as Figure 1 to Figure 6 The shown blood drawing protective cover includes a guide cone 4 that is recessed in the middle and is an inverted cone. A 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 slit, and a circular cover body 3 for inserting the open end of the test tube 6 is provided 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 is placed in the The lower end of the guide cone guide part 4-1 is provided with a groove 3-1 for the insertion of the test tube 6 open ends, and the through hole 5 in the guide cone guide part 4-1 commu...
