Abstract
The utility model belongs to the technical field of a medical instrument and especially relates to a vein blood taking needle. The technical scheme of the disposable vein blood sampling needle is that the disposable vein blood sampling needle is characterized in that the middle part of a hose (3) is divided into two segments, namely a puncture segment (31) connected with a vein puncture needle (1) and a blood sampling segment (32) connected with a blood sampling test tube puncture needle (4). The back end of the puncture segment (31) is fixedly connected with a connection tube (6); the front end of the blood sampling segment (32) is fixedly connected with a casing pipe (7) matching with the connection pipe (6); the connection tube (6) is movably connected with the casting pipe (7); and when the connection tube (6) is movably connected with the casting pipe (7), the hose (3) is sealed and the interior of the hose (3) is communicated. When negative pressure happens and a patient blood vessel collapses and blood sampling work cannot be done, the connection tube (6) can be pulled out of the casing pipe (7) and negative pressure disappears; and blood can enter a test tube via the connection tube (6). The disposable vein blood sampling needle is simply structured with convenient operation.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly a kind of vein blood taking needle.
Background technology
Existing disposable vein blood taking needle adopts negative pressure blood collecting tube, and blood flows to blood sampling test tube by human vein under the effect of negative pressure.This kind of venous blood collection is directed to the poor patients of blood vessel condition such as neonate, infant, old people, because vein caliber is thin, poor flexibility, after puncturing successfully, connect after negative pressure blood-taking tube, a powerful negative pressure usually causes vein blood vessel to subside rapidly, venous blood samples smoothly, or cause haemolysis or blood coagulation phenomenon to affect result of laboratory test.
Utility model content
The purpose of this utility model is: a kind of disposable vein blood taking needle is provided, can overcomes without negative pressure hemostix prior art deficiency.
The technical solution of the utility model is: a kind of disposable vein blood taking needle, comprise venipuncture needle, the pin wing, flexible pipe, blood sampling test tube puncture needle, needle stand, it is characterized in that: in the middle of described flexible pipe, is split up into two sections, is connected with described venipuncture needle for puncture section, what is connected with described blood sampling test tube puncture needle is to take a blood sample section; A described puncture section rear end is fixedly connected with connection tube, and described blood sampling section front end is fixedly connected with the sleeve pipe matching with described connection tube, and described connection tube is flexibly connected with described sleeve pipe, and the described flexible pipe of energy seals and internal communication while connecting.
This utility model will be split up into puncture section, blood sampling section in the middle of flexible pipe, described puncture section is fixedly connected with connection tube, and described blood sampling section is fixedly connected with the sleeve pipe matching with described connection tube.Described connection tube is inserted in described sleeve pipe at ordinary times, when generation cannot be taken a blood sample because negative pressure is subsided patient vessel, connection tube is extracted from sleeve pipe, and negative pressure disappears, and blood enters test tube along connection tube.This utility model is simple in structure, easy to operate.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model structural representation;
Accompanying drawing 2 is this utility model clip (9) front view.
The specific embodiment
Embodiment 1: referring to accompanying drawing 1, a kind of disposable vein blood taking needle, comprise venipuncture needle 1, the pin wing 2, flexible pipe 3, blood sampling test tube puncture needle 4, needle stand 5, it is characterized in that: in the middle of described flexible pipe 3, is split up into two sections, is connected with described venipuncture needle 1 for puncture section 31, what is connected with described blood sampling test tube puncture needle 4 is to take a blood sample sections 32; Described puncture section 31 rear ends are fixedly connected with connection tube 6, and described blood sampling section 32 front ends are fixedly connected with the sleeve pipe 7 matching with described connection tube 6, and described connection tube 6 is flexibly connected with described sleeve pipe 7, and can guarantee that described flexible pipe 3 seals and internal communication during connection.
Described connection tube 6 is inserted in described sleeve pipe 7 at ordinary times, when generation cannot be taken a blood sample because negative pressure is subsided patient vessel, connection tube is transferred to from sleeve pipe 7, and negative pressure disappears, and blood enters test tube along connection tube 6.
Embodiment 2: referring to accompanying drawing 1., a kind of disposable vein blood taking needle, is characterized in that described connection tube 6 and described sleeve pipe 7 are rigid plastics as described in Example 1, and described sleeve pipe 7 is tapered cylinder cylinder, and described connection tube 6 is inserted in described sleeve pipe 7.
Sleeve pipe 7 is made into tapered cylinder cylinder, while making connection tube 6 insert wherein, more steps up, and is convenient to sealing.
Embodiment 3: referring to accompanying drawing 1, a kind of disposable vein blood taking needle, is characterized in that described connection tube 6 is hard material as described in Example 1, and described sleeve pipe 7 is elastic rubber material, and described connection tube 6 is inserted in described sleeve pipe 7.
Embodiment 4: referring to accompanying drawing 1, a kind of disposable vein blood taking needle described in above-described embodiment, is characterized in that described connection tube 6 front ends are provided with inclined-plane 8.The design on inclined-plane is convenient to blood and is splashed into test tube along test tube wall.
Embodiment 5: referring to accompanying drawing 1, accompanying drawing 2, a kind of disposable vein blood taking needle described in above-described embodiment, is characterized in that also comprising clip 9, for clamping or open the path of described puncture section 31.
