A portable midwifery device

Abstract

The invention discloses a portable midwifery device, which belongs to the field of medical equipment, and is characterized in that it includes a suction device, a catheter and a negative pressure device; the two ends of the catheter are respectively connected to the suction device and the negative pressure device, The air between the suction head device and the negative pressure device is connected; the negative pressure device includes a cylindrical tank, and a partition and a piston are arranged in the tank; the partition is fixed in the middle of the tank, The inner part of the tank is divided into upper and lower chambers, i.e. an upper chamber and a lower chamber; the conduit is connected to the lower chamber; the piston is located in the upper chamber, the periphery of the piston is airtightly connected with the inner surface of the tank, and the upper surface of the piston The piston rod is fixedly connected; an air outlet valve is arranged in the lower chamber of the tank body, and the air outlet valve is connected with the lower chamber and the upper chamber. Compared with the prior art, it has the characteristics of adjustable and constant negative pressure.

Description

technical field [0001] The invention relates to a medical device, in particular to a portable midwifery device suitable for delivery of puerpera. Background technique [0002] At present, when the obstetrics fails to deliver newborns to the puerpera, medical staff often need to use midwifery devices to help the fetus deliver. The midwifery devices include a suction device and a negative pressure device. Pressure, the fetal head is pulled by the negative pressure of the suction device, thereby assisting the delivery of the fetus. In actual use, different negative pressure values ​​should be selected according to the actual situation of the mother and the fetus. For example, if the fetal head position is low, 40kpa negative pressure can be used; if the fetal head position is high or the fetus is large, 60kpa negative pressure can be used for those with difficult delivery. 50kpa negative pressure can be selected. [0003] Negative pressure devices include electric negative pr...

AI Technical Summary

Problems solved by technology

Among them, the electric negative pressure suction machine has a complex structure and high cost, and because it needs to be equipped with a power supply, it is not suitable for mobile medical equipment.

However, the manual air extraction device cannot accurately control the negative pressure value of the suction head

In addition, for the manual suction device, if the vacuum is too high, it will easily cause harm to the fetus. During the midwifery process, due to the action of the fetal hair, there will be tiny gaps between the suction head and the fetal scalp. The effect will cause air or amniotic fluid to enter the suction head, thereby reducing the negative pressure in the suction head and causing the suction head and the fetal scalp to fall off. It is necessary to re-attract the suction head to the fetal head, and it is easy to operate for many times fetal head injury
