Description

Anesthesia machine ACGO gas circuit pressure monitoring alarm system

Technical Field

Background

Anesthesia machines are important medical devices used for inhalation anesthesia and respiratory management. Acgo (automatic Common Gas outlet) refers to an auxiliary Common Gas outlet, and is a function of the anesthesia machine configuration. The ACGO outlet can be connected with Bain loops and other open loops, and the problem that carbon dioxide retention is easy to occur in pediatric operations can be effectively solved.

The clinical application of ACGO is that the number of alveoli of children under 4 years old or with the body weight less than 20 kg, especially young children and newborn children is only equal to 1/10 of adults, the surface area of the alveoli is 1/3 of the adult, but the metabolic rate is about twice of that of the adult. Furthermore, the newborn infant has a fast respiratory rate and a limited respiratory reserve, and the oxygen supply of the infant patient must be paid great attention during the operation. For an anesthesia machine with a minimum tidal volume of more than 50ml, the tidal volume is larger than the required upper limit of the neonate, so the neonate in general anesthesia operation cannot use the anesthesia machine to maintain respiration (although the minimum tidal volume of the mei rui anesthesia machine is 20ml, the ACGO interface is configured to enable an anesthesia doctor skilled in using the function to more subjectively sense the respiration condition of the infant). The Bain breathing circuit solves the problem well, and can ensure that the neonate keeps good ventilation in the operation, thereby ensuring the safety of anesthesia and the smooth operation.

The ACGO of the anesthesia machine in the prior art mainly has the following defects: the pressure of current ACGO gas circuit leans on the manometer to show the pressure value, and the operator need observe the manometer numerical value in real time or rely on the size of experience perception air flue pressure, when the operator appears the human negligence, causes harm for the patient because air flue pressure is too high very easily.
