Abstract
The utility model relates to a disposal venous blood sampler and belongs to the technical field of medical appliances. The utility model is composed of a blood sampling pinhead, a flexible pipe, a test tube, a closing plug and an air exhausting balloon. The utility model is characterized in that scale marks are arranged on the outer wall of the test tube, the closing plug is arranged inside the upper end, a catheter which is communicated with the inner cavity of the test tube is arranged on the closing plug, a ball-shaped hollow shell is communicated on the upper end of the catheter, a liquid inlet connector and an air suction connector are respectively communicated on the ball-shaped hollow shell, the blood sampling pinhead is connected on the liquid inlet connector through the flexible pipe, and the air exhausting balloon whose two ends are respectively provided with one-way valves is connected on the air suction connector through a rubber hose. The utility model has the advantages that the structure is simple, the use is safe and convenient, blood is directly inputted into the test tube under the completely closed condition, blood pollution is deduced, and blood sample cells can not be broken.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically disposable vein hemostix.
Background technology
At present, the used utensil of taking a blood sample generally adopts 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 sample of gathering can directly enter test tube, does not destroy the blood sample cell, prevents the contaminated disposable vein hemostix of blood sample.
The purpose of this utility model is achieved in that this disposable vein hemostix is made up of blood collection needles, flexible pipe, test tube, sealing-plug, aerofluxus balloon, the test tube outer wall is provided with scale mark, inside, upper end is provided with sealing-plug, sealing-plug is provided with the conduit that communicates with the test tube inner chamber, the conduit upper end is being communicated with the spherical hollow housing, on the spherical hollow housing, be communicated with liquid inlet joint and air-breathing joint respectively, on liquid inlet joint, the aerofluxus balloon that two ends are respectively equipped with check valve is connected on the air-breathing joint by sebific duct blood collection needles by hose connection.
During use, liquid inlet joint is connected blood collection needles and aerofluxus balloon respectively with air-breathing joint, successfully back extruding aerofluxus balloon punctures, the aerofluxus balloon discharges invisible spectro air sucking-off, the test tube inner chamber forms negative pressure, and blood enters the spherical hollow housing by flexible pipe, by the effect lower edge conduit inflow test tube of gravity, by continuously extruded loosening aerofluxus balloon, blood just can continuously enter test tube.
Advantage of the present utility model: simple in structure, safe and convenient to use, blood directly enters test tube under the complete closed condition, 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 vein hemostix is by blood collection needles 1, flexible pipe 2, test tube 3, sealing-plug 4, aerofluxus balloon 5 is formed, test tube 3 outer walls are provided with scale mark, inside, upper end is provided with sealing-plug 4, sealing-plug 4 is provided with the conduit 6 that communicates with test tube 3 inner chambers, conduit 6 upper ends are being communicated with spherical hollow housing 7, on spherical hollow housing 7, be communicated with liquid inlet joint 8 and air-breathing joint 9 respectively, blood collection needles 1 is connected on the liquid inlet joint 8 by flexible pipe 2, and the aerofluxus balloon 5 that two ends are respectively equipped with check valve is connected on the air-breathing joint 9 by sebific duct.
