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...

Abstract

The invention discloses a blood drawing protection cover. The blood drawing protection cover comprises a guide cone with a guide portion, a guide cone notch is longitudinally formed in one side of the guide cone, a circular cover body is arranged under the guide cone, a groove is formed in the cover body, and a cover body notch is formed in one side of the groove of the cover body; multiple protrusions are circumferentially arranged in the groove of the cover body side by side from top to bottom and are conical protrusions, and multiple radial cracks are formed in each protrusion; the guide cone is a colored transparent resin guide cone, and the cover body is a semi-transparent thermal plastic rubber cover body; the portion, on the other side of the guide cone notch, of the cover body is provided with a rubber sleeve, the sleeve is connected with the cover body through an insertion block and a circular insertion groove formed in the cover body, the insertion block in a wedged shape, and a cross-shaped crack for allowing the insertion block to enter and exit is formed in the outer surface of the circular insertion groove. According to the blood drawing protection cover, the problems that when a blood drawing needle is inserted into a test tube, harm is likely generated to an operator, and the working efficiency is low can be solved.

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...
