Abstract
The present invention relates to a valve-type labor-inducing water sac device, which is composed of a liquid-injecting tube and a water sac. Because the liquid-injecting tube in the water sac is provided with a through hole which is provided with a valve, that the injected liquid enters the water sac, and that the injected liquid can not flow back are ensured. The present invention has the advantages of simple structure, convenient manufacture, a high sterile degree, high reliable performance, etc. The tedious procedures of making the water sac before the operation, of stopping bleeding with a clamp and of stopping bleeding for ligation during the operation are omitted, which shortens operation time, and pains of the operated person can be reduced. In clinic, the present invention can be used for hospitals from all levels.
Description
The present invention relates to a kind of Valved water sac for induced labor.
In " obstetrics and gynecology " teaching material, introduced a kind of induced labor water pocket that is made by catheter and condom, its weak point is: 1, making is loaded down with trivial details before the art, and aseptic degree is low, the infection rate height; 2, the special messenger holds pincers in the art, and assistant's cooperation needs the fluid stopping of clamp liquid injection pipe in gradation between fluid injection in capsule, need the fluid stopping of ligation liquid injection pipe after fluid injection finishes; Operation sequence is many, and it is time-consuming to take the people; The operation receiveing person is painful big.
But task of the present invention provides a kind of independent operation, economizes the people and saves time the Valved water sac for induced labor that aseptic degree is high.
The present invention includes liquid injection pipe and water pocket, it is characterized in that liquid injection pipe and water pocket combine as a whole, be provided with through hole on the liquid injection pipe in water pocket, be provided with valve in the through hole.
Above-mentioned valve can be lamellar, and its two ends are pasted on the liquid injection pipe of through-hole side; Also can be tubular, be placed on the liquid injection pipe of through hole.
Liquid injection pipe of the present invention can select for use rubber, silica gel or non-toxic plastic to make, and water pocket and valve can select for use newborn rubber to make.
The present invention is open or close and control sanguimotor principle design and form according to cardiac valve, it has simple in structure, easy to make, aseptic degree height, advantages such as dependable performance, both can save the loaded down with trivial details program of making clamp fluid stopping and ligation fluid stopping in water pocket and the art before the art, shorten operating time, can alleviate operation receiveing person's misery again.In clinical, the present invention can be widely used in hospitals at different levels.
Below in conjunction with accompanying drawing embodiments of the invention are described further.
Fig. 1 is the structural representation of the embodiment of the invention 1
Fig. 2 is the structural representation of the embodiment of the invention 2
With reference to Fig. 1～Fig. 2, the embodiment of the invention 1 or 2 comprises liquid injection pipe 1 and water pocket 4, and liquid injection pipe 1 and water pocket 4 combine as a whole, and has through hole 3 to be provided with valve 2 at through hole 3 places on the liquid injection pipe 1 in water pocket 4.This valve 2 can be lamellar (referring to Fig. 1), and its two ends are pasted on the liquid injection pipe 1 of through hole 3 sides; Can be tubular (referring to Fig. 2), be placed on the liquid injection pipe 1 at through hole 3 places.When injecting fluid, injection enters water pocket from through hole through the valve side; When water pocket fluidified, valve was close to the fluid injection tube wall, and injection can not be flow backwards.
Claims (3)
1, a kind of Valved water sac for induced labor comprises liquid injection pipe and water pocket, and liquid injection pipe and water pocket combine as a whole, and it is characterized in that being provided with through hole on the liquid injection pipe in water pocket, establishes valve in the through hole.
2, valve induced labor water pocket as claimed in claim 1 is characterized in that valve can be lamellar, and two ends are pasted on the liquid injection pipe of through-hole side.
