Abstract
This utility model relates to disposable lancet, comprise scalp acupuncture, joint, draw point and draw point cover for blood sampling, blood sampling is connected by joint with draw point with scalp acupuncture, and draw point is set on joint below, draw point is in draw point cover, and draw point cover top is the camber structure with cross recess.The apical end of draw point cover is made to cross recess shape, when draw point inserts blood taking tube, draw point inserts rapidly through cross recess, the cross recess of extracting draw point rear distraction from blood taking tube is closed, and in the situation that there is no pressure, residual blood sample just can not overflow like this, has guaranteed medical personnel's safety.
Description
Technical field
This utility model belongs to medical mechanical domain, specifically be disposable lancet.
Background technology
Blood taking needle is conventional medical apparatus and instruments, and it generally comprises scalp acupuncture, joint, draw point and draw point cover for blood sampling, and blood sampling is connected by joint with draw point with scalp acupuncture, and draw point is set on joint below, and draw point is in draw point cover.During use, scalp acupuncture front end syringe needle penetrates in blood vessel, and draw point inserts in blood taking tube, and blood flows into blood taking tube by blood vessel.The draw point cover of existing blood taking needle seals, and when draw point is inserted to blood taking tube, draw point need be pricked and wear draw point cover, and after blood sampling task completes, draw point draw point after blood taking tube is transferred to puts and can leave pin hole, and blood sampling can be overflowed outside needle guard by the remained blood in scalp acupuncture.Overflowing blood can cause susceptible accident potential to medical personnel, has security risk.
Summary of the invention
Technical problem to be solved in the utility model is blood from overflowing draw point cover after blood taking needle is used, and has potential safety hazard, and a kind of safe blood taking needle is provided.
The technical scheme in the invention for solving the above technical problem is: disposable lancet, comprise scalp acupuncture, joint, draw point and draw point cover for blood sampling, blood sampling is connected by joint with draw point with scalp acupuncture, draw point is set on joint below, draw point is in draw point cover, and described draw point cover top is the camber structure with cross recess.
The beneficial effects of the utility model are: the apical end of draw point cover is made to cross recess shape, when draw point inserts blood taking tube, draw point inserts rapidly through cross recess, the cross recess of extracting draw point rear distraction from blood taking tube is closed, in the situation that there is no pressure, residual blood sample just can not overflow like this, has guaranteed medical personnel's safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is draw point cover of the present utility model top schematic diagram;
Label in figure is: 1 blood sampling scalp acupuncture, 2 joints, 3 draw points, 4 draw point covers, 5 draw point cover tops, 6 cross recess.
The specific embodiment
Blood taking needle of the present utility model, comprise scalp acupuncture 1 for blood sampling, joint 2, draw point 3 and draw point cover 4, blood sampling is connected by joint 2 with draw point 3 with scalp acupuncture 1, and draw point cover 4 is arranged on joint 2 belows, draw point 3 is in draw point cover 4, and draw point cover top 5 is the camber structure with cross recess 6.This blood taking needle is simple in structure, and when the cross recess structure that draw point puts makes draw point insert blood taking tube, resistance is little, extracts after draw point, and cross recess is closed, prevents from remaining in the blood from overflowing in blood taking needle, improves safety in utilization.
