Abstract
The utility model relate to a blood sample collecting device which comprises a test tube and an injector. A rubber soft plug is installed on the opening of the test tube in a sealing mode. An injector needle of the injector penetrates through the rubber soft plug and enters the cavity of the test tube. A blood collecting needle is also arranged on the rubber soft plug in a penetrating mode and connected with an infusion needle through a soft catheter, and the infusion needle is used for penetrating into venae of human bodies. The needle point end of the blood collecting needle goes deep into the position close to the bottom end of the test tube, and the needle point end of the injector needle stays on the position closes to the top end of the test tube. An infusion needle handle is installed on the infusion needle, and the infusion needle handle is two section-shaped sheets which are fixedly connected together and arranged symmetrically. The test tube is transparent tube, and a plurality of scale indicating lines are formed in the tube wall in the longitudinal direction at intervals. The blood sample collecting device has the advantages of being simple in structure and convenient to operate, blood collection amount is easily controlled, and the collection process is clean and pollution-free.
Description
Technical field
This utility model belongs to medical test apparatus field, a kind of blood sample collecting device specifically.
Background technology
Blood test is the important inspection item of judgement people health status, often needs to gather clinically the blood of human body sample.The gatherer process of blood of human body sample is: at first use syringe to extract blood of human body, and then the blood transfer in syringe is arrived test tube.There are many shortcomings in this kind blood sample acquisition method in practical operation: 1) for syringe, if use disposablely, can cause waste, if use the non-once of glass, also need syringe is carried out disinfection, increase medical worker's workload; 2) collecting flowchart is too loaded down with trivial details, has increased the contaminated probability of blood in the process of syringe transfer blood sample, can cause result of laboratory test inaccurate; 3) for collection capacity, only can when drawing blood, operating syringe control by rule of thumb, and after transferring in test tube, deviation can appear in collection capacity, waste that amount is many, amount has been lacked can impact chemical examination effect.
The utility model content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, easy to operate, collection capacity is easily controlled and the free of contamination blood sample collecting device of gatherer process health.
For solving the problems of the technologies described above, blood sample collecting device of the present utility model comprises the test tube of top end opening and with the syringe of injection needle, its construction features is to be sealed and installed with the rubber cork on the opening of described test tube, the injection needle of syringe pierces through the rubber cork and enters in vitro chamber, riposte on the rubber cork and be installed with blood collection needles, be connected be used to the infusion needle that thrusts human vein by flexible catheter on blood collection needles.
Adopt said structure, syringe is extracted the air of test tube inner chamber out by injection needle, make the test tube inner chamber form negative pressure, infusion needle thrusts human vein, blood in vein is introduced in vitro under the impact of negative pressure, after blood sampling is completed, injection needle and blood collection needles are extracted from the rubber cork, in vitro namely obtained blood sample; Blood collection procedure is simple, easy to operate, and blood only might touch a little in vitro residual air, and the contaminated probability of blood sample reduces greatly; Syringe does not directly contact blood sample, does not need sterilization, has reduced medical worker's workload.
The needle tip of described blood collection needles is deep into the position near the test tube bottom, and the needle tip of injection needle rests on the position near the test tube top.Adopt this kind structure, make blood directly drop into the bottom of test tube, avoided injection needle to touch blood, reduced to greatest extent the contaminated probability of blood sample.
The transfusion needle handle is installed on described infusion needle.Described transfusion needle handle is for being fixed together and symmetrically arranged two fanning strips.The transfusion needle handle is set, has facilitated medical worker's operation that infusion needle is thrust human vein, the transfusion needle handle adopts the structure of the fanning strip of two symmetries, and having facilitated has an effect simultaneously with two fingers operates acupuncture treatment, and structural design is exquisite, has reduced the acupuncture treatment difficulty.
Described test tube is that on transparent tube and tube wall, ordinate is interval with many graduation indication lines.The graduation indication line is set, has facilitated at any time and observed, thereby can control blood sampling volume easily.
In sum, the utlity model has simple in structure, easy to operate, blood sampling volume is easy to control and the free of contamination advantage of gatherer process health.
Description of drawings
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, a kind of embodiment of blood sample collecting device of the present utility model is to comprise the test tube 1 of top end opening and with the syringe 3 of injection needle 2, be sealed and installed with rubber cork 4 on the opening of test tube 1, the injection needle 2 of syringe 3 pierces through rubber cork 4 and enters in vitro chamber, riposting on rubber cork 4 is installed with blood collection needles 5, is connected be used to the infusion needle 7 that thrusts human vein by flexible catheter 6 on blood collection needles 5.Wherein, for the convenient blood sampling volume of observing, test tube 1 is interval with many graduation indication lines 8 for ordinate on transparent tube and tube wall.Test tube 1 can adopt common transparent glass tube or plastic tube etc.Rubber cork 4 adopts the medical grade rubber materials, still can keep sealing after penetrating syringe needle commonly used in it.Blood collection needles 5 can adopt the various syringe needles of injection, and it is connected with infusion needle 7 by conduit 6.Syringe 3 is taken the air of test tube inner chamber away by injection needle 2, make the test tube inner chamber form negative pressure, infusion needle 7 thrusts human vein, blood in vein is introduced in test tube 1 under the impact of negative pressure, observe the graduation indication line 8 on test tube, after reaching the blood volume that needs, injection needle 2 and blood collection needles 5 are extracted from rubber cork 4, namely obtained blood sample in test tube 1.
With reference to accompanying drawing, the needle tip of blood collection needles 5 is deep into the position near test tube 1 bottom, and the needle tip of injection needle 2 rests on the position near test tube 1 top.This kind structure makes blood can directly enter into the bottom of test tube 1, has also avoided injection needle 2 to touch blood simultaneously, prevents that blood sample is subject to the pollution of injection needle 2.During concrete enforcement, injection needle 2 uses the shorter small pinhead of pin, and blood collection needles 5 can adopt the long large syringe needle of pin.
With reference to accompanying drawing, transfusion needle handle 71 is installed on infusion needle 7.Transfusion needle handle 71 is for being fixed together and symmetrically arranged two fanning strips.The setting of transfusion needle handle 71 is for convenient, infusion needle 7 to be thrust human vein, and the structure that adopts the fanning strip of two symmetries is for convenient having an effect simultaneously with two fingers operates acupuncture treatment, thereby can reduce the difficulty of acupuncture treatment.
In sum, this utility model is not limited to the above-mentioned specific embodiment.Those skilled in the art under the prerequisite that does not break away from spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
