Abstract
The utility model relates to an injector for negative pressure suction. The injector for the negative pressure suction comprises an injector body. The injector for the negative pressure suction is characterized in that the tail portion of the injection body is provided with a lock catch used for fixing a push rod, and the head portion of the injector body is provided with a three-way type control valve. The push rod is provided with sawtooth grooves matching with the lock catch. The three-way type control valve is provided with a liquid inlet and a liquid outlet. The injector for the negative pressure suction has the advantages of being simple in structure, convenient to use, relatively low in cost, economical, durable, and capable of greatly improving work efficiency due to the fact that medical workers do not need to continuously pull to produce negative pressure due to the lock catch, and reducing pollution chance due to the fact that steps of replacing the injector are reduced through the three-way type control valve.
Description
Technical field
This utility model relates to a kind of medical auxiliary apparatus, is specifically related to a kind of vacuum suction syringe.
Background technology
At present, medical aspirator is very frequent and important in the application after clinical operation.Patient often need to near the liquid body exudate aspirator sucking-off operative incision/wound surface, to protect from infection, be convenient to carrying out smoothly of post-operative recovery afterwards in operation.The normally common syringe of existing vacuum extractor adds negative-pressure suction pipe, negative-pressure suction pipe one end is placed on position, operative incision below/wound surface top, the other end connects syringe, by forming negative pressure in syringe, with liquid from the negative-pressure suction pipe inhalation syringe; After syringe is filled with, need the nursing staff that negative-pressure suction pipe is blocked, change syringe, then continue imbibition.So not only complex operation, more increased opportunities for contamination, and expense is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of vacuum suction syringe, to make up the deficiencies in the prior art.
A kind of vacuum suction syringe comprises syringe body, it is characterized in that described syringe body afterbody is provided with for the fixing snap close of push rod, and head is the three way type control valve.
Above-mentioned snap close is provided with sawtooth, and above-mentioned push rod is provided with the serrated slot that matches with the sawtooth of snap close.
Above-mentioned three way type control valve is provided with inlet and leakage fluid dram.
The utility model has the advantage of: simple in structure, easy to use, cost is lower, and economy and durability arranges locker and can make medical personnel needn't continue to pull the generation negative pressure, has greatly increased work efficiency; The three way type control valve can reduce the step of changing syringe, has reduced opportunities for contamination.

The specific embodiment
A kind of vacuum suction syringe comprises syringe body 1, it is characterized in that described syringe body 1 afterbody is provided with for the fixing snap close 3 of push rod 2, and head is three way type control valve 5.
Above-mentioned snap close 3 is provided with sawtooth, and above-mentioned push rod 2 is provided with serrated slot 4, and this serrated slot 4 complements one another with described snap close 3, namely adopts the mode of sawtooth tooth to lock.
Above-mentioned three way type control valve 5 is provided with inlet 6 and leakage fluid dram 7.
When using this utility model, at first open fluid path between three way type control valve 5 and syringe, the leakage fluid dram 7 of three way type control valve 5 is closed, and inlet 6 becomes path with the syringe body row, then drainage tube on patient's health is connected with drainage bag in inlet connected drainage mouth 7; Then pull push rod 2 to make it produce negative pressure, determine corresponding vacuum magnitude according to the scale on syringe body 1.Mutually mate fixing by the snap close 3 that is arranged on syringe body 1 afterbody with the serrated slot 4 on push rod 2, make it produce the continuous negative pressure effect, penetrating fluid in patient's body flows in syringe body 1 under the effect of negative pressure, when the infiltration hydroful, three way type control valve 5 is closed, make leakage fluid dram 7 and syringe body 1 form path, open snap close 3 promotion push rods 2 penetrating fluid is flowed in drainage bag along tee T.
Claims (3)
