Abstract
The utility model relates to a micro negative pressure transfusion device that could make the puncture blood feedback apparent and could be easily observed, comprising a transfusion device needle that the top is connected with a transfusion dropper provided with a micro pressure bag, the utility model could be simply produced with a low cost, and the utility model could be operated easily.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of little negative pressure transfusion device.
Background technology
At present, transfusion device is comprising syringe needle for transfusion device and transfusion drip tube, when giving patient's venipuncture, because syringe needle for transfusion device directly connects transfusion drip tube, and caliber full of liquid more again, the blood back amount is few, and difficulty is seen blood and returned and stay phenomenon, is difficult for observing, be difficult to determine whether syringe needle enters vein, might increase puncture time, increase misery, cause trouble to the operator to the patient.
Summary of the invention
The purpose of this utility model provides a kind of puncture blood back amount little negative pressure transfusion device obvious, that easily observe that makes.
To achieve these goals, the technical scheme that this utility model is taked is: a kind of little negative pressure transfusion device, comprising syringe needle for transfusion device, the upper end of syringe needle for transfusion device is connecting the transfusion device dropper, it waits to levy: design has little negative pressure capsule on the transfusion drip tube of the upper end of syringe needle for transfusion device, and little negative pressure capsule communicates with syringe needle for transfusion device and transfusion drip tube respectively.
The utility model has the advantages that: make easyly, cost is low, because design has little negative pressure capsule on the transfusion drip tube, when pushing little negative pressure capsule, blood back is increased, be convenient to observe, thus the puncture success rate height, for the patient has alleviated misery.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment this utility model is described further:
A kind of little negative pressure transfusion device, as shown in Figure 1, comprising syringe needle for transfusion device 1, the upper end of syringe needle for transfusion device 1 is connecting transfusion device dropper 3, design has little negative pressure capsule 2 on the transfusion drip tube 3 of the upper end of syringe needle for transfusion device 1, little negative pressure capsule 2 has the 20cm place apart from syringe needle for transfusion device 1, be " Semen Persicae or cylinder " type, volume is about 0.25ml, little negative pressure capsule 2 communicates with syringe needle for transfusion device 1 and transfusion drip tube 3 respectively, and is when puncturing to the patient, that little negative pressure capsule 2 is overlapping with syringe needle for transfusion device 1, suitably the little negative pressure capsule 2 of extruding makes and produces negative pressure in the transfusion device, blood back is abundant, obviously, improve puncture success rate, reduced patient's misery.
