Abstract
The utility model relates to a blood collecting device, which belongs to the technical field of blood collecting device structures. The blood collecting device comprises a venous puncture needle, a test tube puncture needle and a hose, wherein the venous puncture needle is provided with a first needle guard; the test tube puncture needle is provided with an elastic protection jacket; the hose is used for connecting the venous puncture needle with the test tube puncture needle; a second needle guard is sleeved on the test tube puncture needle and the elastic protection jacket; and the upper end of the test tube puncture needle is provided with an inverted-U-shaped anti-loosening buckle which can just clamp the lower edge of a tube cap of a vacuum blood collecting tube, so that the elastic protection jacket is prevented from ejecting the test tube puncture needle away from the tube cap of the vacuum blood collecting tube. The blood collecting device disclosed by the utility model is simple in structure, and is convenient to operate; and the anti-loosening buckle on the upper part of the test tube puncture needle is tightly matched with the tube cap of the blood collecting tube, so that the test tube puncture needle is always positioned in an enclosed blood collecting space, the needle tube is prevented from being separated, blood leakage pollution is avoided, and the safety of medical personnel is protected.
Description
Technical field
This utility model relates to a kind of blood-taking device, belongs to disposable blood-taking device technical field of structures.
Background technology
At present, disposable blood taking needle commonly used generally comprises venipuncture needle, flexible pipe and puncture of test tube pin three parts.Wherein the outer flexible rubber protecting jacket of puncture of test tube pin can avoid blood excessive, is used for continuous many test-tube bloods collection.In use find, when the operator takes on the other hand new test tube or gets cotton swab and can not bimanualness the time, because the elasticity of puncture of test tube pin rubber protecting jacket is larger, easily puncture of test tube pin bullet is covered from vacuum test tube, and then cause leaking blood, pollute.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and provides simple and direct, easy to operate, the difficult generation of a kind of structure to leak the blood-taking device that blood stains dye.
A kind of blood-taking device of the present utility model, comprise venipuncture needle 1 with the first needle guard 2, with the puncture of test tube pin 3 of elastic protecting sleeve 4 and with the flexible pipe 5 of the two connection, cover has the second needle guard 6 on puncture of test tube pin 3 and the elastic protecting sleeve 4, special character is that puncture of test tube pin 3 upper ends are provided with fastener 7, fastener 7 is inverted U, the lower edge of pipe cap 9 just in time can be blocked with crotch in two ends, prevent elastic protecting sleeve 4 with puncture of test tube pin 3 bullets from plug 10; Fastener 7 is moulded goods for elasticity, can untie easily buckle, carries out the replace tubes blood sampling.
On vacuum test tube 8 mouths of pipe pipe cap 9 is arranged, pipe cap 9 centers are for being used for the plug 10 of puncture of test tube pin puncture.
A kind of blood-taking device of this utility model; simple in structure; easy to operate; by the design to puncture of test tube pin top fastener; cooperatively interacting of itself and blood taking tube pipe cap is in the blood sampling space of sealing the puncture of test tube pin all the time, prevents that needle tubing breaks away from; avoid leak that blood stains dye, protection medical personnel safety.
Description of drawings
Fig. 1: the structural representation of a kind of blood-taking device of this utility model;
Among the figure: 1: venipuncture needle; 2: the first needle guards; 3: the puncture of test tube pin; 4: elastic protecting sleeve; 5: flexible pipe; 6: the second needle guards; 7: fastener; 8: vacuum test tube; 9: pipe cap; 10: plug.
The specific embodiment
Referring to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.
A kind of blood-taking device of present embodiment; comprise venipuncture needle 1 with the first needle guard 2, with the puncture of test tube pin 3 of elastic protecting sleeve 4 and with the flexible pipe 5 of the two connection; cover has the second needle guard 6 on puncture of test tube pin 3 and the elastic protecting sleeve 4, and puncture of test tube pin 3 upper ends are provided with fastener 7.Described fastener 7 is inverted U, and the lower edge of pipe cap 9 just in time can be blocked with crotch in two ends, prevent elastic protecting sleeve 4 with puncture of test tube pin 3 bullets from plug 10; Fastener 7 is moulded goods for elasticity, can untie easily buckle, carries out the replace tubes blood sampling.
On vacuum test tube 8 mouths of pipe pipe cap 9 is arranged, pipe cap 9 centers are for being used for the plug 10 of puncture of test tube pin puncture.
During use, take off the first needle guard 2, after venipuncture 1 is punctured for patient's ulnar vein, the puncture of test tube pin 3 that takes off the second needle guard 6 is passed elastic protecting sleeve 4, the plug 10 of puncture vacuum test tube 8 enters in the vacuum test tube 8.The crotch hasp at fastener 7 two ends is in pipe cap 9 times along upper, prevent elastic protecting sleeve 4 with puncture of test tube pin 3 bullets from plug 10, fix after making puncture of test tube pin 3 enter the blood taking tube vacuum tube chamber of vacuum, blood flows into vacuum test tube.
A kind of blood-taking device of this utility model; simple in structure; easy to operate; by the design to puncture of test tube pin top fastener; closely cooperating of itself and blood taking tube pipe cap is in the blood sampling space of sealing the test tube blood taking needle all the time, prevents that needle tubing breaks away from; avoid leak that blood stains dye, protection medical personnel safety.
