Problems solved by technology

The controllable air bag midwifery that appeared in the early 1990s has helped many pregnant women relieve pain and reduce the probability of cesarean section; however, there are two problems in the existing controllable air bag midwifery: first, the diameter of the air bag is It is obtained through the simulation calculation of the pressure change of the air tank, and the error is relatively large, up to ±10%. Test to finally determine the balloon diameter
The controllable balloon midwifery has hardly changed in the past two decades, which has brought a lot of inconvenience and troubles to the clinical application of this technology

Abstract

The invention discloses a full-automatic bionic air-bag midwifery instrument and belongs to the field of medical equipment. The instrument comprises an air bag, an air pump, an air storage tank and an automatic control system, wherein the air bag is connected with an air bag handle, and an air channel is formed in the air bag handle; the air bag handle is connected with an inflation valve and a bleed valve, the other end of the inflation valve is connected with the air storage tank, and the air storage tank is connected with the air pump through a non-return valve; the automatic control system comprises a keyboard control system and an analog-to-digital conversion control system; an output end of the keyboard control system is connected with the analog-to-digital conversion control system and further comprises a foot switch; the analog-to-digital conversion control system comprises a first pressure sensor, a second pressure sensor and an alarm prompting system; the first pressure sensor is connected with the air storage tank, the non-return valve and one end of the inflation valve; the second pressure sensor is connected with the air bag, the other end of the inflation valve and the bleed valve; the alarm prompting system gives alarm prompt tones when the pressure of the air storage tank and the diameter of the air bag meet requirements. According to the instrument, the diameter of the air bag is accurate.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to the structure of an airbag bionic obstetrical instrument. Background technique [0002] With the continuous development of computer and sensor technology, many electronic products, including medical devices, have begun to be widely controlled by embedded microcomputers and various sensors. The current ultrasonic diagnostic technology is also very mature. In human reproductive health and eugenics, Ultrasonic diagnostic technology plays an irreplaceable role. The controllable air bag midwifery that appeared in the early 1990s has helped many pregnant women relieve pain and reduce the probability of cesarean section; however, there are two problems in the existing controllable air bag midwifery: first, the diameter of the air bag is It is obtained through the simulation calculation of the pressure change of the air storage tank, and its error is relatively large, reaching a maxim...
