Abstract
This utility model belongs to technical field of medical instruments, be specifically related to a kind of negative pressure drainage device, comprise flexible pipe and syringe, also comprise three-way valve and collecting bag, described three-way valve comprises valve body and is arranged on the spool in body cavity, by the position of spool in regulating three-way valve, make syringe and flexible pipe or syringe and collecting bag conducting, realize the suction to wound bed fluid, liquid is pushed collecting bag, is convenient to observe liquid.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of negative pressure drainage device.
Background technology
At present, the Thyroid gland puncture drainage device used clinically, all that puncture needle connects drainage tube draining hole, during operation, puncture needle is passed outside skin by Intradermal, draining hole is stayed Intradermal, then puncture needle is cut off, by skin closure, by drainage tube, needle tubing is connected with syringe, repeatedly aspirated by syringe and the liquid in wound is extracted out, syringe need be changed when liquid reaches a certain amount of in syringe, now nurse then needs drainage tube to fold and clutches to keep the negative pressure in wound constant, careless slightly, just have gas and enter wound, cause unnecessary trouble, liquid repeatedly aspirates discharge by syringe simultaneously, be difficult to metering and observe, certain negative effect is had to follow-up treatment.
Utility model content
The technical problems to be solved in the utility model is to provide one and is convenient to keep negative pressure, is convenient to the negative pressure drainage device observing extracted liquid simultaneously.
The technical solution of the utility model is: a kind of negative pressure drainage device, comprise flexible pipe and syringe, also comprise three-way valve and collecting bag, described three-way valve comprises valve body and is arranged on the spool in body cavity, described valve body comprises main body, first siphunculus, second siphunculus and tee T, described main body is circular tube structure, described first siphunculus, second siphunculus and tee T are along the circle distribution of described tubular body, and be communicated with described tubular body, described spool is placed in the inner chamber of described tubular body, and be connected with described body seal, described spool is cylindric, be provided with in its underpart and described first siphunculus, be interconnected three through holes that second siphunculus and tee T position relationship match, the top of described spool is provided with knob, described flexible pipe, syringe and collecting bag are tightly connected with described first siphunculus, the second siphunculus and tee T respectively.
Further, described valve inner is provided with packing ring, and valve body and spool are arranged by washer sealing.
Further, described syringe is 5---10mL.
Further, described collecting bag is transparent material, which is provided with scale.
The beneficial effects of the utility model: when placing drain in thyroid operation art, described flexible pipe is cut to appropriate length, cut 2-3 side opening, be placed in above thyroid sternal notch, draw from otch side, and be fixed on otch, connect a three-way valve, another termination 5mL asepsis injector of three-way valve, rotational valve core after syringe pump hydrops, make syringe and collecting bag conducting, liquid in syringe is pushed rotational valve core after collecting bag, flexible pipe and syringe conducting is made again to aspirate hydrops, repetition like this is for several times until extract out without obvious hydrops, the visible local dent of flap, syringe needle guard is fixed on syringe tail end, adhesive tape is wound around, get final product stable maintenance negative pressure, finally with adhesive tape, syringe is fixed on shoulder, rotational valve core is got final product when drainage-fluid exceedes over half in syringe, liquid in syringe is pushed in collecting bag, and keep negative pressure, be convenient to like this observe extracted liquid, simultaneously easy and simple to handle.
