Abstract
The utility model relates to a medical instrument, in particular to a novel blood collector for blood test. The technical scheme is that the novel blood collector comprises a blood collection needle head, a control valve, a blood collection tube, a syringe, a piston and a blood outlet tube, wherein the piston is arranged in the syringe; the bottom of the syringe is connected with the blood outlet tube; the blood collection needle head is arranged at the tail end of the blood outlet tube; the control valve is arranged on the blood outlet tube; a spring is arranged between the top of the syringe and a handle at the tail end of the piston; and the syringe is movably connected with the handle at the tail end of the piston through a latch. The utility model has the beneficial effects that the novel blood collector is simple in structure; and blood can be uniformly extracted by utilizing the expansion and contraction of the spring, so that the pain of a patient is alleviated.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and hemostix is used in particularly a kind of novel blood test.
Background technology
At present, in medical and health industry, medical test is the effective way to medical diagnosis on disease; Often will use blood taking needle blood is tested, the test tube that used very now blood sampling and splendid attire blood are used is disposable plastic test tube basically, at first takes a blood sample on human body with blood taking needle when in use; Then blood is moved in the test tube, blood will in air, expose a period of time, especially this section from syringe to the process that in vitro shifts blood sample; Cause blood to spatter easily outward, cause environmental pollution, blood sample also can be polluted simultaneously; The blood sample cell is damaged easily, and then influences the accuracy of assay.The Chinese patent document number is that CN201958891U discloses a kind of " the special-purpose disposable blood taking needle of blood test "; Its structure comprises blood collection needles, syringe, piston; Blood collection needles is connected the syringe front end through blood taking tube; The rearward end of this blood taking tube stretches in the syringe and a puncture needle is set, and has and the corresponding puncture needle placing trough of puncture needle at the leading section of piston, and the anterior hollow of piston has a cavity; The front end of above-mentioned syringe is also installed and is provided with blood and goes out pipe, and described blood taking tube, blood go out on the pipe to be provided with flow control valve.Adopt manually pulling piston but remain, have the uneven situation of speed, cause blood draw not at the uniform velocity, cause bigger misery to the patient.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists to prior art, provides a kind of novel blood test to use hemostix, can extract blood uniformly through telescopic spring, has alleviated patient's misery.
Its technical scheme is: comprise by blood collection needles, control valve, blood taking tube, syringe, piston and go out blood vessel; Be provided with piston in the described syringe; The bottom of syringe connects blood vessel, and the end that goes out blood vessel is provided with blood collection needles, goes out blood vessel and is provided with control valve; Be provided with spring between the top of described syringe and the end hand grip of piston, snap close flexibly connects the end hand grip of syringe and piston.
The beneficial effect of this utility model is: it is simple in structure, can extract blood uniformly through telescopic spring, has alleviated patient's misery.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model;
Among the last figure: blood collection needles 1, control valve 2, blood taking tube 3, syringe 4, piston 5, spring 6, go out blood vessel 8 at snap close 7.
The specific embodiment
In conjunction with accompanying drawing 1, this utility model is done further to describe:
This utility model comprises by blood collection needles 1, control valve 2, blood taking tube 3, syringe 4, goes out blood vessel 8; Be provided with piston 5 in the described syringe 4; The bottom of syringe 4 connects blood vessel 8, and the end that goes out blood vessel 8 is provided with blood collection needles 1, goes out blood vessel 8 and is provided with control valve 2; Be provided with spring 6 between the end hand grip of the top of described syringe 4 and piston 5, snap close 7 flexibly connects the end hand grip of syringe 4 with piston 5.
During blood sampling, open snap close 7, piston is applied strength, avoid pulling the imbalance of the moving piston application of force, can alleviate patient's misery through spring 6 stretching, extensions.
