Abstract
A vacuum positioner of a transfusion puncture needle belongs to the technical field of medical appliance. When the scalp acupuncture transfusion is carried out on some elder patient who has a low venous pressure and no blood returning in a hospital, whether or not the syring needle is entered into the blood vessel cannot be ensured, and the normal proceed of the transfusion is disturbed, and troubles will be brought to the operation of the medical care personnel at the same time. The technical proposal of the utility model is: a syring needle 4 with a stator 2, a fine plastic transfusion tube 5, a vacuum extruding air pocket 1, and a coarse plastic transfusion tube 3 are orderly fixed and communicated with each other. A switch 6 is positioned on the coarse plastic transfusion tube 3. The utility model has the advantages that the vacuum positioner of the transfusion puncture needle is rational and practical in structure and is skillful and novel in designing. With the utility model, the rapid blood returning can be fulfilled to ensure that the syring needle has entered into the blood vessel by the vacuum extruding air pocket action after the syring needle is pierced into the blood vessel, so that the operation is simple, the transfusion frequency is improve and the workload of the care personnel can be lightened.
Description
Technical field: this utility model relates to the medical device technical field, is vein puncture pin negative pressure positioner more specifically.
Background technology: when carrying out intravenous infusion with winged needle set, meet the low not blood back of some elderly patients' vein pressures in the hospital and can't determine that syringe needle whether in the intravasation, has hindered normally carrying out of transfusion, making troubles to medical personnel's operation simultaneously to patient.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of vein puncture pin negative pressure positioner of design.Its technical scheme is: the syringe needle 4 of band stator 2, thin plastic infusion pipe 5, negative pressure extruding gasbag 1 and thick plastic infusion pipe 3 are fixedly connected sequentially and communicate, and thick plastic infusion pipe 3 is provided with switch 6.The advantage of this utility model is: the practicality reasonable in design of this vein puncture pin negative pressure positioning device structure, novelty is skillfully constructed, thereby use it can realize the definite syringe needle of rapid blood back intravasation by the action of negative pressure extruding gasbag with syringe needle puncture back, it manipulates simple and convenient, has improved transfusion efficient and has also alleviated medical personnel's medical care precess amount of labour simultaneously.
Description of drawings: this accompanying drawing is this utility model structural representation.In the accompanying drawing: 1, negative pressure extruding gasbag, 2, stator, 3, thick plastic infusion pipe, 4, syringe needle, 5, thin plastic infusion pipe, 6, switch.
The specific embodiment: the syringe needle 4 of band stator 2, thin plastic infusion pipe 5, negative pressure extruding gasbag 1 and thick plastic infusion pipe 3 are fixedly connected sequentially and communicate, and thick plastic infusion pipe 3 is provided with switch 6.When infusing to elderly patients, thrust subcutaneously with syringe needle 4, close switch 6 then, thereby extruding negative pressure extruding gasbag 1 makes and keeps negative pressure state that blood is refluxed in the pipeline determining to open switch 6 then and infuse in syringe needle 1 intravasation.
Claims (1)
1, vein puncture pin negative pressure positioner, it is characterized in that: the syringe needle (4) of band stator (2), thin plastic infusion pipe (5), negative pressure extruding gasbag (1) and thick plastic infusion pipe (3) are fixedly connected sequentially and communicate, and thick plastic infusion pipe (3) is provided with switch (6).
