An inflatable film midwifery device

Abstract

The invention relates to an inflatable film obstetric apparatus, belonging to the field of medical equipment. The inflatable film obstetric apparatus is characterized by comprising a casing and a control host, wherein the casing is a cylindrical sleeve which is composed of two layers of films and has two open ends, and a sealed inflation space is formed between the two layers of films. The inflatable film obstetric apparatus abandons the structure that a support arm of an original support rod is pushed open, the two layers of films are inflated by gas so as to wrap the head of a fetus, and the fetus is pulled out through the casing. The inflation volume and deflation volume are controlled by a control system and an inflation pump according to production processes; the structure of the inflatable film obstetric apparatus is reasonable; when the inflatable film obstetric apparatus is used, the fetus can not be injured; and the operation is very simple, the pain of a pregnant woman caused by delivery is reduced while the delivery process is accelerated, and thus the fetus is prevented from being injured in the delivery process. More than two one-way air supply valves are arranged on an inside film at the inner end, the one-way air supply valves only can supply air to the outside of the inflation space, and the one-way air supply valves directly correspond to the mouth and nose of the fetus, thereby ensuring the oxygen supply of the fetus and reducing the danger coefficient in delivery.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an inflatable film midwifery device. Background technique [0002] Childbirth is a normal physiological process for pregnant women. Most pregnant women can give birth naturally from the vagina. In order to speed up the delivery process, reduce the pain of childbirth for pregnant women, and prevent the fetus from being injured during delivery, there are two commonly used instruments for midwifery. : One is the suction device midwifery. It uses the principle of negative pressure suction to suck the fetal head suction device to the top of the fetal skull, and when the uterus contracts and the mother breathes in, the fetus is sucked out with the help of the suction device. The structure of the equipment required by this method is complicated, and the operation needs to be operated by relevant medical technology professionals. The other is to use forceps to assist delive...

AI Technical Summary

Problems solved by technology

In the course of practice, the applicant found that the above-mentioned patented technology depends to some extent on the technical ability of the physician, such as setting more than three strut arms at the end of the strut set for pushing the strut set to the fetal head. , the strut arm is naturally stretched around, which drives the membrane sleeve to wrap the fetal head, and pulls the fetus out through the membrane sleeve. However, since the strut set and its strut arm are parts with certain hardness, the When advancing and touching the fetal head, if it cannot be deployed in time, continuing to advance will harm the fetal body

In addition, the oxygen tube is set on the innermost layer of the membrane sleeve to provide oxygen supply to the fetus during delivery, but practice has proved that when the fetus is pulled out from the womb, the membrane sleeve is tightly attached to the fetus' face, and the oxygen tube is compressed , unable to supply sufficient oxygen in time, bringing unnecessary danger to childbirth
