Abstract

The utility model discloses a blood collection device, and relates to a medical inspection appliance. The blood collection device consists of a blood collector (1), a test tube (2) and an air suction ball (3), wherein the blood collector (1) consists of a blood collection needle (11), a blood sample catheter (12) and a test tube cover (13); the blood collection needle (11) is connected to one end of the blood sample catheter (12); the other end of the blood sample catheter (12) passes through the test tube cover (13); the test tube (2) and the test tube cover (13) are connected and sealed by a polished ring; and one end of an air suction tube (31) is connected to the air suction ball (3), and the other end of the air suction tube (31) is inserted into an air suction tube insertion opening (15) of the test tube cover (13). According to the blood collection device, a syringe is replaced by the blood collector, blood is adjusted by the vacuum degree of the air suction ball and automatically flows into the test tube, and a blood sample which is sucked into the syringe is not required to be transferred into the test tube, so that blood collection cost is reduced, and the working strength of medical inspection personnel is lightened; and the blood collection device can be widely applied in medical inspection institutions.

Description

A kind of blood-taking device

Technical field

This utility model relates to the medical test utensil, employed a kind of blood-taking device when relating in particular to a kind of collection venous blood.

Background technology

The clinical blood check is one of routine inspection project of medical test, and the clinical blood check can be divided into blood routine examination and blood biochemical check.Blood routine examination is to puncture fully the blood capillary at inspection person's finger top to draw a little blood sample with tubule, and during the biochemical investigation blood-sample withdrawal, the blood volume of collection is more relatively, so must adopt patient's vein blood.The situation of gathering venous blood at present is such: because the vacuum test tube price is high; Have certain shortcomings such as failure chance during blood sampling; So; Medical inspection mechanism gathers blood sample and all adopts plastic injector for temporary use, extracts blood appearance with syringe from patient's vein, the blood sample in the syringe is transferred to sent control laboratory to test in the test tube then.The drawback of this way is: 1, exhausted plastic injector for temporary use is all discarded, has caused very big waste, has strengthened the cost of blood sampling; 2, complex operation; The medical test personnel need twitch pintle and could be drawn into needle tubing to blood during blood sampling, then blood sample are transferred to test tube from syringe, have strengthened medical test personnel's working strength and workload; Especially the out-patient for a long time, the medical test personnel are very tired.

Summary of the invention

This utility model does not use syringe when being to provide a kind of blood-sample withdrawal, and blood sample directly gets into test tube, does not need to transfer to test tube again, and simple in structure, easy to use, cheap a kind of blood-taking device.

In order to reach above purpose, the technical scheme that this utility model is taked is: this a kind of blood-taking device is become by hemostix, test tube, air-breathing set of balls.It is characterized in that: hemostix is made up of blood taking needle, blood sample conduit and test tube lid; Blood taking needle is connected an end of blood sample conduit, and the other end of blood sample conduit passes the test tube lid, and its open-ended also is angled section; The height that is shorter in length than test tube that the blood sample conduit passes, the blood sample conduit is provided with switch; The interior warp of test tube lid is complementary with test tube external diameter suitable for reading, and polishing is connected sealing to test tube with the test tube lid, and test tube covers and also is provided with the suction nozzle socket; One end of suction nozzle is connected on the air-breathing ball, and the other end of suction nozzle is inserted on the suction nozzle socket of test tube lid.

When using this utility model, the medical test personnel insert the test tube lid with the test tube mouth, and the open end of suction nozzle is inserted on the airway socket of test tube lid; Pinch air-breathing ball with hands then, after the air scavenge in the air-breathing ball is gone out, close the supravasal switch of blood sample; Blood taking needle is thrust inspection person's vein fully, open the supravasal switch of blood sample, blood flows into test tube by the blood sample conduit automatically; Air in the test tube is discharged into air-breathing ball, when treating that the blood sample that flows in the test tube reaches some, closes the supravasal switch of blood sample; Take off blood taking needle, test tube is covered to take down to be equipped with from test tube check, the suction nozzle on the air-breathing ball is covered from test tube take off; Be equipped with the next bit patient use of taking a blood sample, hemostix is abandoned into medical waste.

The beneficial effect of this utility model is: this a kind of blood-taking device has substituted syringe by hemostix; Blood leans on the vacuum of air-breathing ball to regulate and flow into automatically test tube; The blood sample that does not need to be drawn into syringe shifts into test tube again; Reduce the blood sampling cost, alleviated medical test personnel's working strength; Can be widely used in medical test mechanism.
