Abstract
The invention discloses an efficient negative pressure blood collector which comprises a needle head (1), a Y-shaped tee joint (4) and a negative pressure blood bag (8). The efficient negative pressure blood collector is characterized in that a protecting shell (2) is arranged outside the needle head (1), the free end of the Y-shaped tee joint (4) is connected with a negative pressure ball (10) through a control valve (9), one end of the Y-shaped tee joint (4) is connected with the needle head (1) through a needle head base (3), the tail end of the Y-shaped tee joint (4) is connected with the negative pressure blood bag (8) through a blood collecting hose (5), a sealing part is arranged on the neck of the negative pressure blood bag (8) and composed of a puncture head (6) and an elastic sealing ring (7), and the puncture head (6) is arranged in the center of the elastic sealing ring (7). The efficient negative pressure blood collector is simple and novel in structure and easy to operate, and is a safe negative pressure blood collector.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of high-efficiency negative-pressure hemostix.
Background technology
The disposable blood taking needle of blood sample collection use clinically at present, front end is a scalp acupuncture, and end is a syringe needle, syringe needle overcoat rubber case, the way of existing hospital the needle portion of hemostix is cut to be placed in sharp instrument box, but careless slightly namely easily by pricking wound in transport process.
The hemostix of current use, under special circumstances, as: when patient circulate extreme exhaustion, become thin, blood vein pressure is lower, and disposable blood taking tube negative pressure is not enough, when using disposable blood taking needle collection inadequate blood volume, blood is just to having outflowed, have to blood taking needle be extracted, again with disposable syringe puncture blood drawing, so both add the misery of patient, turn increase the workload of staff, bring very large inconvenience to work.In addition, because bloodletting tube is separated with syringe needle, flexible pipe, bloodletting tube is separated with storage blood vessel, easily causes the pollution of blood.
Summary of the invention
In order to overcome above-mentioned defect, the object of the present invention is to provide a kind of high-efficiency negative-pressure hemostix, simple novel, the operation simplification of structure is a kind of hemostix of safety negative-pressure.
The technical solution used in the present invention is:
A kind of high-efficiency negative-pressure hemostix, comprise syringe needle (1), Y shape threeway (4) and negative pressure blood bag (8), it is characterized in that, described syringe needle (1) outer setting protecting sheathing (2), the free-end of described Y shape threeway (4) connects negative pressure ball (10) by control valve (9), one end of Y shape threeway (4) is by needle holder (3) connecting needle (1), the end of Y shape threeway (4) connects negative pressure blood bag (8) by blood drawing flexible pipe (5), the cervical region of negative pressure blood bag (8) arranges sealing member, the seal is made up of puncturing head (6) and elastic seal ring (7), puncturing head (6) is arranged on the center of elastic seal ring (7).
Further, described protecting sheathing (2) is plastic conduit.
Further, described negative pressure blood bag (8) arranges containing mark.
Beneficial effect of the present invention is:
1, negative pressure ball is connected at the free-end of Y shape threeway by control valve, achieve conventional disposable negative-pressure hemospast function, be convenient to staff run into when taking a blood sample blood vessel negative pressure not enough time, can directly with negative pressure ball from the threeway of Y shape by blood extract out, avoid repetition venipuncture, time saving and energy saving, can patient suffering be alleviated.
2, the present invention is structure as a whole on the whole, the cervical region of negative pressure blood bag arranges and forms sealing member by puncturing head and elastic seal ring, puncturing head is arranged on the center of elastic seal ring, good airproof performance, under negative pressure state, be conducive to blood to flow directly in negative pressure blood bag, avoid the results such as the haemolysis that the pollution of blood and maloperation cause.
3, syringe needle is hidden before blood drawing at syringe needle outer setting protecting sheathing by the present invention; ensure hemostix in transport process syringe needle not by pricking wound; ensure that air pollution avoided by syringe needle, hides syringe needle after blood drawing completes simultaneously, avoid the syringe needle that misoperation causes and stab or pollute.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1, syringe needle; 2, protecting sheathing; 3, needle holder; 4, Y shape threeway; 5, blood drawing flexible pipe; 6, puncturing head; 7, elastic seal ring; 8, negative pressure blood bag; 9, control valve; 10, negative pressure ball.
Detailed description of the invention
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1; a kind of high-efficiency negative-pressure hemostix; comprise syringe needle 1, Y shape threeway 4 and negative pressure blood bag 8; it is characterized in that; described syringe needle 1 outer setting protecting sheathing 2; the free-end of described Y shape threeway 4 connects negative pressure ball 10 by control valve 9; one end of Y shape threeway 4 is by needle holder 3 connecting needle 1; the end of Y shape threeway 4 connects negative pressure blood bag 8 by blood drawing flexible pipe 5; the cervical region of negative pressure blood bag 8 arranges sealing member; the seal is made up of puncturing head 6 and elastic seal ring 7, and puncturing head 6 is arranged on the center of elastic seal ring 7.
Further, described protecting sheathing 2 is plastic conduit.
Further, described negative pressure blood bag 8 arranges containing mark.
Concrete use procedure is: taken off by syringe needle 1 outer setting protecting sheathing 2; the free-end opening Y shape threeway 4 connects the control valve 9 of negative pressure ball 10; pinch pressure negative pressure ball 10; syringe needle 1 is inserted the blood vessel place of patient with blood drawing liquid simultaneously; draw blood; after blood is extracted out, the free-end of closedown Y shape threeway 4 connects the control valve 9 of negative pressure ball 10, make blood pass through blood drawing flexible pipe 5 and flow directly into negative pressure blood bag 8.
Above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-described embodiment, the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
