Abstract

The utility model discloses a cutting edge negative-pressure drainage pack for breast surgery. The cutting edge negative-pressure drainage pack comprises a pack body and a push-pull piston injector, wherein the pack body is provided with a liquid inlet tube, a drain tube and an exhaust tube; the liquid inlet tube, the drain tube and the exhaust tube are provided with control valves for controlling the ventilation and closing of tube bodies; and the air inlet end of the push-pull piston injector is connected with the pack body through the exhaust tube. When the cutting edge negative-pressure drainage pack is used, the pack body is vacuumized into a negative-pressure state through the push-pull piston injector, and the liquid inlet tube is connected with a drainage tube, so that liquid is drained into the pack body under the action of negative pressure. When a large amount of drainage liquid is filled in the pack body, the control valve of the drain tube is opened to drain the drainage liquid, and the pack body is vacuumized into the negative-pressure state through the push-pull piston injector for repeated use. The cutting edge negative-pressure drainage pack has the advantages of simple structure, convenience for using, low cost and the like.

Description

A kind of mammary gland surgery edge of a knife negative pressure drainage bag
Technical field
This utility model relates to a kind of mammary gland surgery with edge of a knife negative pressure drainage bag, belongs to medical instruments field.
Background technology
Mammary gland edge of a knife negative pressure drainage is the operation that must carry out behind the mammary gland surgical operation, it is the successful important assurance of performing the operation, suitable negative pressure drainage can make the art district be the persistence negative pressure state, can play the effect of abundant drain, to the dead space between oozing of blood, sepage and the elimination wound surface of control postoperative wound surface, prevention of postoperative infection has the important clinical meaning.In addition, the volume of metering drain liquid can help the doctor to judge the healing and the rehabilitation of patients situation of the edge of a knife, all needs drain every day, when every day, drainage flow was lower than 10 milliliters, just can pull out drainage tube.Common clinically negative pressure drainage device mainly contains at present: wall type central negative pressure drainage device, lower negative pressure electric suction apparatus, disposable negative pressure drainage ball etc., and these apparatus structure complexity, cost is higher, and this has limited its clinical applying.
Summary of the invention
At above-mentioned prior art, this utility model provides a kind of mammary gland surgery simple in structure edge of a knife negative pressure drainage bag, and it is easy to use, and cost is lower.
This utility model is achieved through the following technical solutions:
A kind of mammary gland surgery edge of a knife negative pressure drainage bag, comprise bag, also comprise plug-type piston syringe, described bag is provided with feed tube, discharging tube and exhaustor, wherein, be equipped with ventilation of control body and the control valve of closing on feed tube, discharging tube and the exhaustor, the inlet end of plug-type piston syringe is connected with bag by exhaustor.
Described bag is provided with scale.
Described plug-type piston syringe can be common common plug-type piston syringe, can be following structure also: comprise transparent cylindrical shell (front end of transparent cylindrical shell is an inlet end), piston and piston rod, piston is positioned at transparent cylindrical shell, and being connected the piston rod front end, piston rod is provided with elastomeric element.
Described transparent cylindrical shell is provided with scale.
Described control valve is the control folder.
During use, close the control valve of feed tube and discharging tube, open the control valve of exhaustor, by plug-type piston syringe bag is pumped into negative pressure state, close the control valve (plug-type piston syringe is extracted, connected again behind the piston reset) of exhaustor then, feed tube is connected with drainage tube, open the control valve of feed tube, then liquid under suction function by drain to bag.Can read the volume of drain liquid by the scale on the bag.When drain liquid is too much in the bag, close the control valve of feed tube, open the control valve of discharging tube, drain liquid is discharged.After closing the control valve of discharging tube, by plug-type piston syringe bag is pumped into negative pressure state again, uses so repeatedly.When the intravital liquid volume of range estimation bag is less than 10 milliliters, plug-type piston syringe can be received on the discharging tube, liquid is sucked in the transparent cylindrical shell, with accurate measurement liquid volume, to judge whether to reach the condition that can pull out drainage tube.In the time can pulling out drainage tube, mammary gland surgery of the present utility model taken off with edge of a knife negative pressure drainage bag get final product.
This utility model is when taking out negative-pressure operation, people's operation gets final product: when piston rod is pulled out, because the existence of negative pressure, for preventing rebounding of piston rod, this utility model is provided with elastomeric element on piston rod, elastomeric element is that to be contracted in transparent tube intravital when piston does not have pull to put in place, when the piston pull put in place, elastomeric element stretched out in transparent cylindrical shell, withstood on the end face of transparent cylindrical shell, stop rebounding of piston, at this moment, the operator can decontrol plug-type piston syringe, removes closed control valve thereby vacate hands, cooperate thereby need not two people, people's operation gets final product.When needing return piston, pinch elastomeric element with hands, elastomeric element can be retracted in the transparent cylindrical shell.
The utlity model has simple in structure, easy to use, low cost and other advantages.
