Abstract

The utility model discloses a disposable convenient blood sampler used in a testing laboratory, which comprises a needle head (1), a handheld handle (2), a piston handle (3) and a piston (4). The handheld handle (2) is arranged on the needle head (1). The disposable convenient blood sampler is characterized in that a handheld disc (5) is arranged at the base end of the piston handle (3), a needle base (6) is connected to the handheld disc (5), a flow passage (7) is arranged inside the piston handle (3), the pipe cavity of the needle base (6) is communicated with the flow passage (7), a test tube (8) is arranged at the rear end of the handheld disc (5) and is sheathed outside the piston handle (3) and the piston (4), and the flow passage (7) passes through the piston (4) to be communicated with the bottom cavity of the interior of the test tube (8). The disposable convenient blood sampler has simple structure, is convenient for use, can reduce use cost and avoid cross contamination, and can directly sample blood into the test tube under a completely-sealed condition.

Description

Control laboratory disposable and convenient hemostix

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically a kind of control laboratory disposable and convenient hemostix.

Background technology

At present, the used hemostix of hospital laboratory mostly is syringe greatly, comprises that puncture needle, conduit, syringe, piston, piston handle constitute, and after in the venous blood suction syringe, are divided in vitro according to lab work and chemically examine.The weak point of this hemostix is: easily infected after in blood is adopted syringe to the different processes of in vitro injecting respectively, also cause cross infection simultaneously easily; It is 200420099304.X " can directly adopt the disposable vein negative pressure hemostix into test tube " that Chinese patent discloses the patent No., its structure is made of puncture needle, conduit, syringe, piston, piston handle, though this hemostix can directly be adopted blood sample in vitro under the condition of sealing fully, but complex structure, increased use cost, be not suitable for promoting the use of.

Summary of the invention

The purpose of this utility model be to provide a kind of not only simple in structure, can reduce use cost, and easy to use, can avoid cross infection, can fully the sealing condition under blood sample is directly adopted into the control laboratory of test tube disposable and convenient hemostix.

For reaching above purpose, the technical scheme that this utility model adopted is: this control laboratory disposable and convenient hemostix, constitute by syringe needle, hand holding handle, piston handle and piston, hand holding handle is located on the syringe needle, it is characterized in that being provided with hand-held disk at the seat end of piston handle, on hand-held disk, connect needle stand, in piston handle, be provided with runner, the tube chamber of needle stand is connected with runner, rear end at hand-held disk is provided with test tube, test tube is set in the outside of piston handle and piston, and runner passes piston and is connected with the inner bottom part chamber of test tube.

This utility model is also implemented by following measure: the inner bottom surface shape of described piston end face shape and test tube matches, and after test tube was shifted the end onto, piston end face was adjacent to the interior diapire of test tube, prevents from vitro to have air; The outer wall of described test tube is provided with scale, can in time observe aspiration in aspiration procedure.

The beneficial effects of the utility model are: not only simple in structure, can reduce use cost, and easy to use, can avoid cross infection, can under the condition of sealing fully, blood sample directly be adopted into test tube.

The specific embodiment

Make this utility model with reference to accompanying drawing 1,2.This control laboratory disposable and convenient hemostix, constitute by syringe needle 1, hand holding handle 2, piston handle 3 and piston 4, hand holding handle 2 is located on the syringe needle 1, it is characterized in that being provided with hand-held disk 5, on hand-held disk 5, connect needle stand 6, in piston handle 3, be provided with runner 7 at the seat end of piston handle 3, the tube chamber of needle stand 6 is connected with runner 7, rear end at hand-held disk 5 is provided with test tube 8, and test tube 8 is set in the outside of piston handle 3 and piston 4, and runner 7 passes piston 4 and is connected with the inner bottom part chamber of test tube 8.

This utility model is also implemented by following measure: the inner bottom surface shape of the end surface shape of described piston 4 and test tube 8 matches, and after test tube 8 was shifted the end onto, the end face of piston 4 was adjacent to the interior diapire of test tube 8, prevents that test tube 8 internal memories from having air; The outer wall of described test tube 8 is provided with scale 9, can in time observe aspiration in aspiration procedure.

When using this utility model, hands takes hand holding handle 2 to puncture, and after puncturing successfully, pinches the hand-held disk 5 of seat end of piston handle 3 with the finger of a hands, the another hands is arrested test tube 8, outwards spur test tube 8, can be the direct suction test tube 8 of blood, at this moment, can directly send into the laboratory, send in the process in laboratory again, can not need to extract piston 4, can be used as the test tube plug and use this moment.

Claims

1. control laboratory disposable and convenient hemostix, by syringe needle (1), hand holding handle (2), piston handle (3) and piston (4) constitute, hand holding handle (2) is located on the syringe needle (1), it is characterized in that being provided with hand-held disk (5) at the seat end of piston handle (3), go up connection needle stand (6) at hand-held disk (5), in piston handle (3), be provided with runner (7), the tube chamber of needle stand (6) is connected with runner (7), rear end at hand-held disk (5) is provided with test tube (8), test tube (8) is set in the outside of piston handle (3) and piston (4), runner (7) passes piston (4), is connected with the inner bottom part chamber of test tube (8).

2. control laboratory disposable and convenient hemostix according to claim 1 is characterized in that the end surface shape of described piston (4) and the inner bottom surface shape of test tube (8) match; The outer wall of described test tube (8) is provided with scale (9).
