Abstract
The utility model provides a surgical instrument of a dual negative pressure system, which consists of a negative pressure suction bottle and a negative pressure system which is connected by a pipeline; the negative pressure system is composed of a vacuum pump negative pressure generator and a centralized type negative pressure supply device; and a switching valve is arranged between the vacuum pump negative pressure generator and the centralized type negative pressure supply device. The switching valve can be a three-way valve which is provided with two valve imports and one valve export; both the valve imports are respectively connected with the vacuum pump negative pressure generator and the pipeline of the centralized type negative pressure supply device; the valve export is connected with the negative pressure suction bottle. As the advantages of two kinds of negative pressure systems are integrated, the utility model can lead the operator to make a reasonable choice according to the actual circumstance and adopt an appropriate negative pressure system, thereby improving the surgical efficiency and safety.
Description
One, technical field
This utility model relates to the surgery apparatus of negative pressure system, and the obstetrics and gynecology operation instrument of especially two negative pressure systems relates to the negative pressure switching device shifter, especially negative pressure generator and hospital's centralizedly supply negative pressure switching device shifter in the machine of negative pressure surgery apparatus.
Two, background technology
At the existing vacuum extractor that is used for obstetrics and gynecology operation, substantially all be to adopt vacuum pump to produce negative pressure.Perhaps, provide the centralizedly supply negative pressure in some hospital with good conditionsi.This dual mode respectively has advantage.Adopt the systematic comparison of vacuum pump flexible, can start at any time, in the system that does not possess the centralizedly supply negative pressure, can use, bigger but shortcoming is a noise.And the system of centralizedly supply negative pressure is relatively cleaner, and the efficient height does not have noise, but requires hospital foundation conditional request height.
Three, summary of the invention
The purpose of this utility model is: propose a kind of pair of negative pressure system and switchable surgery apparatus, especially the vacuum extractor surgery apparatus.
Technical solution of the present utility model is: the surgery apparatus of two negative pressure systems, the negative pressure system that is connected with pipeline by the vacuum suction bottle constitutes, negative pressure system is vacuum pump negative pressure generator and centralized negative voltage supply device, it is characterized in that being provided with transfer valve between vacuum pump negative pressure generator and the centralized negative voltage supply device.
This utility model can comprehensive two kinds of negative pressure systems advantage, make the operator can be according to practical situation, choose reasonable adopts suitable negative pressure system, improves the efficient and the safety of operation.
Four, description of drawings
Fig. 1 is a structural representation of the present invention
Five, the specific embodiment
Shown in Fig. 1, in the negative pressure surgery apparatus, be provided with the interface of vacuum pump negative pressure generator 3 and concentrated negative voltage supply device 4.
In system, be provided with the negative pressure switching device shifter,, be used for a cover of two cover negative pressure is switched to the work negative pressure as transfer valve 5.In this system, at first be equipped with a cover vacuum pump negative pressure system, reach the interface of external concentrated negative voltage supply, and then connect two cover supply systems with transfer valve, its delivery outlet is linked liquid containing bottle, uses during for operation.(seeing accompanying drawing).Advantage that like this can comprehensive two kinds of negative pressure systems makes the operator can be according to practical situation, and choose reasonable adopts suitable negative pressure system, improves the efficient and the safety of operation.Draw operation suction pipe 6 again from vacuum suction bottle 1.
Described transfer valve 5 can be a three-way valve, be provided with two valve imports and an outlet, valve outlet port of two valve imports connects the pipeline and the vacuum suction bottle of vacuum pump negative pressure generator, centralized negative voltage supply device respectively, and the different valve import when diverse location of valve block connects with outlet (being connected the vacuum suction bottle).
Transfer valve also can be that two stop valves are contained in respectively on the connecting line of centralized negative voltage supply device and vacuum pump negative pressure generator, is contained in two intermediary pipelines of stop valve and is connected with the vacuum suction bottle.Stop valve is that electromagnetic valve or mechanical valve all can.
When adopting centralized negative voltage supply device, centralized negative voltage supply device 4 connects pressure-regulating valves 7 earlier and connects transfer valve or stop valve again.
