Abstract
The utility model relates to a disposable hemostix, which belongs to the technical field of medical appliances. The disposable hemostix consists of a needle tube (1), a test tube (2), an axis tube (3), a needle head (4) and a piston (5). The utility model is characterized in that the test tube (2) with the outer diameter adapting to the inner diameter of the needle tube (1) is glidingly sheathed inside the needle tube (1), mutually symmetrical handles (6) arranged on the back section of the test tube (2) respectively pass through mutually symmetrical axial notches (7) arranged on the back section of the needle tube (1) to be exposed out of the needle tube (1), the outer end of the axis tube (3) fixed in the center of the front end surface of the needle tube (1) is connected with the needle head (4), the piston (5) adapting to the inner diameter of the test tube (2) is connected and fixed on the outer wall of the inner end of the axis tube (3). The disposable hemostix has a simple structure and is simple and convenient to operate, and collected blood samples can directly enter the test tube without damaging blood sample cells, so the detection results are accurate.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of disposable blood taking device.
Background technology
At present, the used utensil of taking a blood sample generally is a disposable syringe, and it is that syringe needle with hollow syringe front end thrusts veins beneath the skin, with blood suction syringe, and then is injected in vitro.This traditional approach formality is loaded down with trivial details, and troublesome poeration spatters outside easy from syringe blood when in vitro shifting blood sample, not only easy contaminated environment, and destroy the blood sample cell easily, influence the accuracy of testing result.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of blood sample of gathering can directly enter the disposable blood taking device of test tube.
The purpose of this utility model is achieved in that this disposable blood taking device is made up of syringe, test tube, axle center pipe, syringe needle, piston, syringe slides within suit the test tube that external diameter and syringe internal diameter adapt, and symmetrical handle is exposed at the syringe outside after passing axial gap symmetrical above the syringe back segment respectively above the test tube back segment; The pipe outer end, axle center that is fixed on syringe front end face center links to each other with syringe needle, is being connected and fixed the piston that adapts with the test tube internal diameter on the inner outer wall.
Outwards spur test tube after puncturing successfully, blood just is drawn in vitro by syringe needle, axle center pipe.
Advantage of the present utility model: simple in structure, easy and simple to handle, the blood sample of being gathered can directly enter test tube, does not destroy the blood sample cell, makes testing result accurate.
Description of drawings
Accompanying drawing is a structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this disposable blood taking device is made up of syringe 1, test tube 2, axle center pipe 3, syringe needle 4, piston 5, syringe 1 slides within suit the test tube 2 that external diameter and syringe 1 internal diameter adapt, and symmetrical handle 6 is exposed at syringe 1 outside after passing axial gap 7 symmetrical above syringe 1 back segment respectively above test tube 2 back segments; The axle center that is fixed on syringe 1 front end face center is managed 3 outer ends and is linked to each other with syringe needle 4, is being connected and fixed the piston 5 that adapts with test tube 2 internal diameters on the inner outer wall.
Claims (1)
1. disposable blood taking device, form by syringe (1), test tube (2), axle center pipe (3), syringe needle (4), piston (5), it is characterized in that syringe (1) slides within suit the test tube (2) that external diameter and syringe (1) internal diameter adapt, test tube (2) above the back segment symmetrical handle (6) pass syringe (1) respectively and be exposed at syringe (1) outside behind the symmetrical axial gap (7) above the back segment; Pipe (3) outer end, axle center that is fixed on syringe (1) front end face center links to each other with syringe needle (4), is being connected and fixed the piston (5) that adapts with test tube (2) internal diameter on the inner outer wall.
