Abstract

The utility model discloses a fetal head suction, comprising a conical hollow drum. The fetal head of the conical hollow drum is nested with a rubber sleeve; the small end of the conical hollow drum is connected with two corresponding short handles; a hollow pipe is arranged inside the small end, and the hollow pipe is communicated with the intra-cavity of the fetal head by means of a unidirectional valve; the other end of the hollow pipe stretches out of the small end of the conical hollow drum; and the middle part of a small pipe is provided with a unidirectional valve communicated with the outside. With simple structure and convenient operation, the utility model can shorten the delivery time, thereby reducing the possibility of hurting the fetus.

Description

A kind of vacuum extractor

One, technical field

This utility model relates to a kind of armarium, a kind of vacuum extractor of assisting fetus to quicken childbirth of more specifically saying so.

Two, background technology

At present, be used to assist the medical apparatus and instruments of fetus birth to mainly contain negative pressure vacuum extractor and obstetric forceps in the hospital, but these two kinds of apparatuses in use at present, uses inconvenience, delivery time is longer, easily fetus is formed damage.

Three, summary of the invention

The purpose of this utility model provides vacuum extractor a kind of easy to use, simple in structure.

The purpose of this utility model is to be achieved by following technical proposals.

Vacuum extractor of the present utility model, it includes the empty tube of a taper, be with a rubber case on the fetal head end of the empty tube of described taper, the thin termination of the empty tube of taper has the short handle of two correspondences, in the thin end hollow pipe is arranged, and communicate with the inner chamber of fetal head end by a unidirectional flap valve, the other end of described hollow pipe stretches out the thin end of the empty tube of taper, also has a unidirectional flap valve with exterior in the middle of tubule.

This utility model is simple in structure, and is easy to use, can shorten delivery time, is difficult for fetus is formed damage.

Four, description of drawings

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model.

Five, specific embodiment

In Fig. 1, a kind of vacuum extractor of the present utility model, it includes the empty tube 5 of a taper, be with a rubber case 1 on the fetal head end 6 of the empty tube 5 of described taper, the thin end 8 of the empty tube 5 of taper is connected to the short handle 2 of two correspondences, and carefully holding has a hollow pipe 3 in 8, and communicates with the inner chamber of fetal head end 6 by a unidirectional flap valve 4, the other end of described hollow pipe 3 stretches out the thin end 8 of the empty tube 5 of taper, also has a unidirectional flap valve 7 with exterior in the middle of tubule 3.

During use, can be with the hollow pipe 3 external negtive-pressure implements of tubule 8, after starting negtive-pressure implement, unidirectional flap valve 4 is opened, unidirectional flap valve 7 sealings, thereby make the inner chamber of the fetal head end 6 of the empty tube 5 of taper produce negative pressure, when the head of fetus enters fetal head end 6, can hold firmly, assist the fetus childbirth, owing to be with a rubber case 1 on the fetal head end 6 of the empty tube 5 of taper, be difficult for the head of fetus is caused damage.
