Abstract
The utility model provides a negative pressure fetal head aspirator and belongs to the technical field of medical instruments. The aspirator structurally comprises a sucker and a negative pressure suction pipe. The wide opening end of the sucker is arranged in the axis direction of the negative pressure suction pipe, the shrinkage opening end of the sucker is connected with the front end of the negative pressure suction pipe in sealing mode, an air discharge valve switch and a pressure meter are communicated with the pipe wall of the negative pressure suction pipe, a holding handle is arranged on the negative pressure suction pipe, and a bellows connector is arranged at the tail end of the negative pressure suction pipe. The negative pressure fetal head aspirator adopts matching arrangement of the air discharge valve switch and the pressure meter, is capable of enabling users to grasp intervals of operation conditions of negative pressure values on one hand and releasing or adjusting pressure in the sucker matched with use of the air discharge valve switch under special conditions on the other hand, effectively increases operation parameters of operations and increases odinopoeia success ratio.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of negative pressure vacuum extractor.
Background technology
General, vacuum extraction is that the suction pump collar extension is placed on the fetal head that exposes, the reuse syringe forms negative pressuren zone with air sucking-off in the suction pump, utilizes the vacuum suction principle, holds fetal head, cooperates uterine contraction, the fetal head of giving birth to.The syringes of a constant volume that adopt provide negative pressure more under the prior art, are mostly the free-hand operation of surgical staff, and its negative pressure value is fluctuated, instability, and the risk that then can occur disposable attraction failure during misoperation takes place.
Summary of the invention
The technical assignment of this utility model is the deficiency that solves prior art, and a kind of negative pressure vacuum extractor is provided.
The technical scheme of this utility model realizes by following mode; This negative pressure vacuum extractor, its structure comprise sucker, negative pressure-pumping pipe, and the wide mouth part of sucker is arranged on the negative pressure-pumping tube axis direction; The necking end of sucker is connected with negative pressure-pumping pipe forward end seal; Be communicated with on the tube wall of negative pressure-pumping pipe and unload air valve switch and Pressure gauge, the negative pressure-pumping pipe is provided with holds handle, and negative pressure-pumping pipe end is provided with corrugated pipe connector.
The beneficial effect that this utility model is compared with prior art produced is:
This negative pressure vacuum extractor adopts and unloads air valve switch and manometric being equipped with; The interval that can grasp the operating condition of negative pressure value on the one hand; On the other hand as cooperate when special circumstances occurring the use of unloading air valve switch the pressure in the sucker to be discharged or regulate; More effective raising operation technique parameter increases the induced labor success rate.
Work as fetal distress in uterus, can adopt this negative pressure vacuum extractor to finish childbirth as early as possible.Fetus is big, when the puerpera is exhausted, can help fetus to descend.Relative obstetric forceps, this negative pressure vacuum extractor is few to the soft birth canal injury chance, and fetus maternal infuries chance also is less than obstetric forceps.This negative pressure vacuum extractor is simple to operate, be easy to grasp, and is safe and reliable, easy to use, be easy to safeguard to have good operation popularizing value.
