The utility model relates to a quantitative blood sampling device, which solves the problem of inconvenience in blood sampling of the existing finger. Including the blood sampling body to and locate the sacculus of blood sampling body one end, the other end of blood sampling body is the blood collection mouth, and the one end that the blood sampling body is close to the blood collection mouth is blood holding chamber, and the other end is restriction ball stroke chamber, through front end shrink mouth intercommunication between blood holding chamber and the restriction ball stroke chamber, through rear end shrink mouth intercommunication between restriction ball stroke chamber and the sacculus, restriction ball stroke intracavity is equipped with the restriction ball. Hold between the fingers the gasbag and make the gas in the gasbag extrude from the gas outlet, then plug up the gas outlet, restriction ball this moment is located front end shrink mouth department, then loosen the gasbag, take a blood sample through taking a blood mouthful, restriction ball removes to the back end shrink mouth this moment, when restriction ball removes and plugs up the back end shrink mouth, the sacculus no longer admits air, the blood is no longer inhaled to the blood mouth, at this moment, blood just in time is inhaled full blood holding chamber, then through extruding the sacculus, extrude other blood test wares with the blood base in. Thereby can absorb quantitative blood, convenient to use is swift.

Description

Quantitative blood sampling device
Technical Field
The utility model relates to a quantitative blood sampling device.
Background
Finger blood sampling is a common clinical blood sampling mode and is easy to accept by patients. At present, finger blood sampling is basically carried out by pricking fingertips with needles each time, removing blood suction with blood vessels after bleeding, and putting blood into a glass test tube after sucking blue threads. The blood sampling at present has the problems that the blood sampling tube is made of glass, is very fragile and thin, is easy to break due to improper operation, sudden action of fingers and the like in the operation process, is not safe and easily causes blood splashing. Meanwhile, blood pumped into the blood sampling tube is not easy to transfer into the glass test tube, and the rubber ball is commonly used for pressurizing to enable the blood to enter the glass test tube, but the blood is often sucked into the rubber ball carelessly, so that the blood waste is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem that the existing finger blood sampling is inconvenient.
The technical scheme adopted for solving the technical problems provided by the utility model is as follows: the quantitative blood sampling device comprises a blood sampling tube body and a balloon arranged at one end of the blood sampling tube body, wherein the other end of the blood sampling tube body is a blood sampling port, the blood sampling tube body is divided into two sections, one section of the blood sampling tube body, which is close to the blood sampling port, is a blood accommodating cavity, the other section of the blood sampling tube body is a ball stroke limiting cavity, the blood accommodating cavity is communicated with the ball stroke limiting cavity through a front end contraction port, the ball stroke limiting cavity is communicated with the balloon through a rear end contraction port, a limiting ball used for plugging the front end contraction port or the rear end contraction port is arranged in the ball stroke limiting cavity, the diameter of the limiting ball is smaller than that of the ball stroke limiting cavity, and an air outlet is formed in the balloon.
The technical scheme for further limiting the utility model comprises the following steps:
the bottom of the sacculus is provided with a clamping groove in interference fit with the blood sampling tube body, and the blood sampling tube body is clamped in the clamping groove.
The rear end contraction port is a conical contraction port arranged in the middle of the bottom of the balloon.
The front end contraction opening is gradually enlarged from the middle to two sides.
The blood holding cavity is provided with scales.
The blood sampling tube body is made of plastic or glass.
The limiting ball is made of a silica gel material.
Through the technical scheme, the utility model has the beneficial effects that: when the quantitative blood sampling device is used, the air bag is pinched to extrude gas in the air bag from the air outlet, then the air outlet is blocked, the limiting ball is positioned at the front end contraction opening, then the air bag is loosened to sample blood through the blood sampling opening, the limiting ball moves towards the rear end contraction opening, when the limiting ball moves to block the rear end contraction opening, the air is not fed into the air bag, the blood sampling opening does not suck blood, at the moment, the blood is just sucked into the blood accommodating cavity, and then the blood is extruded into other blood test vessels by extruding the air bag. Thereby can absorb quantitative blood, convenient to use is swift.
Drawings
Fig. 1 is a schematic structural view of a quantitative blood sampling device according to the present invention.
Fig. 2 is a sectional structure view of a quantitative blood sampling device according to the present invention.
Detailed Description
The structure of the present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1 and 2, a ration blood sampling device is including blood sampling body 1, and locate the sacculus 2 of blood sampling body one end, the other end of blood sampling body 1 is blood taking port 11, the blood sampling body divide into two sections, one section that the blood sampling body is close to the blood taking port is blood holding chamber 12, another section is restriction ball stroke chamber 13, communicate through front end throat 14 between blood holding chamber and the restriction ball stroke chamber, communicate through rear end throat 15 between restriction ball stroke chamber and the sacculus, restriction ball stroke intracavity is equipped with and is used for the restriction ball 3 that plugs up front end throat or rear end throat, the diameter of restriction ball is less than the diameter in restriction ball stroke chamber, the restriction ball can roll in the restriction ball stroke intracavity, be equipped with gas outlet 21 on the sacculus. The diameter of the air outlet is smaller than the width of the fingers, so that the air outlet can be directly plugged by the fingers during use, and the operation is convenient. The blood collection tube body can be made of plastic or glass. The restriction ball may be made of a silicone material. In this embodiment, the rear-end constriction is a tapered constriction disposed in the middle of the bottom of the balloon. The front end contraction opening is gradually enlarged from the middle to two sides. During the use, hold between the fingers the gasbag and make the gas in the gasbag extrude from the gas outlet, then plug up the gas outlet, restriction ball this moment is located front end shrink mouth department, then loosen the gasbag, take a blood sample through the mouth of taking a blood sample, restriction ball removes to the back end shrink mouth this moment, when the restriction ball removes to plug up the back end shrink mouth, the sacculus no longer admits air, the blood of taking a blood sample mouth no longer inhales blood, at this moment, blood just in time inhales full blood holding chamber, then through extruding the sacculus, extrude blood in other blood test dishes. Thereby can absorb quantitative blood, convenient to use is swift.
In this embodiment, the bottom of sacculus 2 is equipped with the draw-in groove 22 with blood sampling body interference fit, and the blood sampling body joint is in the draw-in groove. Thereby the saccule and the blood sampling pipe mouth are arranged in a sealing way.
In this embodiment, the blood containing cavity is provided with scales 4. Different sizes of blood containing cavities can be selected as required.
While the present invention has been described in detail and with reference to the accompanying drawings, it is not to be construed as limiting the scope of the utility model. Various modifications and changes may be made by those skilled in the art without inventive step within the scope of the present invention as described in the appended claims.
