Abstract
Disclosed is a test tube blood sampling device, belonging to the technical field of medical devices. The utility model is composed of a base (1), a test tube (2), a closure plug (3), a hose (4), a blood sampling needle (5) and an exhaust balloon (6). The utility model is characterized in that the test tube (2) is nested inside a sleeve (7) provided with a window on the base (1); the closure plug (3) is arranged on the upper end inside the test tube (2); the closure plug (3) is respectively provided with an exhaust tube (8) and a liquid inlet tube (9) which are communicated with the intra-cavity of the test tube (2); the upper end of the exhaust tube (8) is connected with the exhaust balloon (6); and the upper end of the liquid inlet tube (9) is connected with the blood sampling needle (5) by means of the hose (4). With simple structure and safe and convenient using, the utility model has the advantages that the test tube is placed stably, so the blood can directly go into the test tube, and the blood is reduced to be polluted without destroying the cells of the blood samples.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of test tube blood-taking 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 a kind of test tube blood-taking device that blood sample pollutes.
The purpose of this utility model is achieved in that this test tube blood-taking device is made up of base, test tube, sealing-plug, flexible pipe, blood collection needles, aerofluxus balloon, test tube is sleeved in the sleeve that has form above the base, inside, test tube upper end is provided with sealing-plug, be respectively equipped with the exhaustor and the feed tube that communicate with the test tube inner chamber on the sealing-plug, exhaustor upper end is connected with the aerofluxus balloon, and the feed tube upper end is by hose connection blood collection needles.
When specifically using this utility model, test tube is placed in the sleeve above the base, connect the aerofluxus balloon in the upper end of exhaustor, successfully back extruding aerofluxus balloon punctures, the aerofluxus balloon discharges invisible spectro air sucking-off, and the test tube inner chamber forms negative pressure, and blood sucks test tube by flexible pipe and feed tube, by continuously extruded aerofluxus balloon, blood can continuously be inhaled in the test tube.
Advantage of the present utility model: simple in structure, safe and convenient to use, test tube is placed stable, and blood can directly enter 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 test tube blood-taking device is made up of base 1, test tube 2, sealing-plug 3, flexible pipe 4, blood collection needles 5, aerofluxus balloon 6, test tube 2 is sleeved in the sleeve 7 that has form above the base 1, inside, test tube 2 upper end is provided with sealing-plug 3, be respectively equipped with the exhaustor 8 and the feed tube 9 that communicate with test tube 2 inner chambers on the sealing-plug 3, exhaustor 8 upper ends are connected with aerofluxus balloon 6, and feed tube 9 upper ends are connecting blood collection needles 5 by flexible pipe 4.
Claims (1)
