Abstract
The utility model provides a disposable test tube type blood donor set, belonging to the medical equipment technology, which comprises a plastic test tube (1), a sealing bung (2), an exhaust pipe (3), a liquid inlet pipe (4), an one-way air escape valve (5), an one-way liquid inlet valve (6), a plastics collapsible tube (7) and a blood taking needle tip (8). The sealing bung (2), which is arranged at the superior extremity of the plastics test tube (1), is provided with exhaust pipe (3) and liquid inlet pipe (4) that is connected with the inner cavity of the plastics test tube (1) respectively. The utility model is characterized in that the superior extremity of the exhaust pipe (3) is connected with the one-way air escape valve (5), and the superior extremity of the liquid inlet pipe (4) is connected with the one-way liquid inlet valve (6), the blood taking needle tip (8) is connected with the one-way liquid inlet valve (6) through plastics collapsible tube (7). The utility model has the advantages of simple in structure and convenient in use, blood enters the test tube directly and the blood contamination is reduced without damage to cells in blood sample.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of disposable test blood sampling tube device.
Background technology
At present, the used utensil of taking a blood sample generally is to adopt 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, in the time of in injecting tube, destroys the blood sample cell easily; When carrying out various blood examination, also to repeatedly from test tube, extract blood sample, cause blood sample to pollute easily.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of blood of gathering can directly enter test tube, does not destroy the blood sample cell, prevents the disposable test blood sampling tube device that blood sample pollutes.
The purpose of this utility model is achieved in that this disposable test blood sampling tube device is made up of plastic test tube, sealing-plug, exhaustor, feed tube, one-way exhaust valve, unidirectional feed liquor valve, plastic flexible pipe, blood collection needles, the plastic test tube upper end is provided with sealing-plug, be respectively equipped with the exhaustor and the feed tube that communicate with the plastic test tube inner chamber on the sealing-plug, the upper end of exhaustor is connected with one-way exhaust valve, the feed tube upper end is connected with unidirectional feed liquor valve, and blood collection needles is connected on the unidirectional feed liquor valve by plastic flexible pipe.When specifically using this utility model, the extruding plastic test tube is discharged invisible spectro air by exhaustor and one-way exhaust valve after puncturing successfully, the test tube inner chamber forms negative pressure, blood sucks test tube by unidirectional feed liquor valve and feed tube, by continuously extruded test tube, blood can continuously suck in the test tube.
This utility model has following actively useful effect: simple in structure, easy to use, blood directly enters test tube, reduces blood contamination, does not destroy the blood sample cell.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this disposable test blood sampling tube device is made up of plastic test tube 1, sealing-plug 2, exhaustor 3, feed tube 4, one-way exhaust valve 5, unidirectional feed liquor valve 6, plastic flexible pipe 7, blood collection needles 8, plastic test tube 1 upper end is provided with sealing-plug 2, be respectively equipped with the exhaustor 3 and the feed tube 4 that communicate with plastic test tube 1 inner chamber on the sealing-plug 2, the upper end of exhaustor 3 is connected with one-way exhaust valve 5, feed tube 4 upper ends are connected with unidirectional feed liquor valve 6, and blood collection needles 8 is connected on the unidirectional feed liquor valve 6 by plastic flexible pipe 7.
Claims (1)
1, disposable test blood sampling tube device, by plastic test tube (1), sealing-plug (2), exhaustor (3), feed tube (4), one-way exhaust valve (5), unidirectional feed liquor valve (6), plastic flexible pipe (7), blood collection needles (8) is formed, plastic test tube (1) upper end is provided with sealing-plug (2), be respectively equipped with the exhaustor (3) and the feed tube (4) that communicate with plastic test tube (1) inner chamber on the sealing-plug (2), the upper end that it is characterized in that exhaustor (3) is connected with one-way exhaust valve (5), feed tube (4) upper end is connected with unidirectional feed liquor valve (6), and blood collection needles (8) is connected on the unidirectional feed liquor valve (6) by plastic flexible pipe (7).
