Description

A kind of novel blood collecting pen

Technical field

This utility model relates to a kind of medical device, particularly a kind of novel blood collecting pen.

Background technology

In the prior art, chemical examination department in the hospital extracts the blood collecting pen that is adopted when micro blood is simply chemically examined, because of in the shaft of a writing brush, being provided with blood taking needle, though avoided the aerial pollution of blood taking needle, when operating, still needed to poke skin with syringe needle earlier, then with capillary tube blood sampling sampling, because syringe needle and capillary tube are placed apart, blood is exposed to for a long time and causes cross infection in the air easily, and gets the capillary tube troublesome poeration in addition.

The utility model content

Technical assignment of the present utility model is to provide a kind of novel blood collecting pen at above prior art deficiency.The technical scheme that its technical problem that solves this utility model adopts is: a kind of novel blood collecting pen, this blood collecting pen comprises the syringe needle and the shaft of a writing brush, the described shaft of a writing brush is a flat, in the described shaft of a writing brush, also be provided with capillary tube, described syringe needle and capillary tube are fastened in the shaft of a writing brush by latch closure, syringe needle and capillary tube top are equipped with elastic device, syringe needle links to each other with the button of being located at shaft of a writing brush both sides respectively with the capillary tube side, shaft of a writing brush both sides are respectively equipped with two grooves that respond with button up and down, and the medical worker can be by regulating button control syringe needle or the length of capillary tube outside the shaft of a writing brush.

This utility model can produce following beneficial effect:

1, syringe needle is placed with capillary tube, can take a blood sample immediately after poking skin, has avoided cross infection;

2, reasonable in design, simple to operate.
