Electric continuous flow device of circulation loop

Abstract

An electric continuous flow device of a circulation circuit relates to a continuous flow device of a circulation loop, and solves the problems that a semi-open anesthetic loop for pediatric anesthesia causes low respiratory efficiency, the unutilized oxygen and volatile anesthetics are discharged into the atmosphere, medical resources are wasted, the environment is polluted, and a pediatric anesthetic close circulation loop has large resistance and high respiratory power consumption. A disc flow deflector is fixedly installed on a fan blade and is positioned at one side of an air inlet side, the external diameter of the disc flow deflector is d1, the external diameter of the fan blade is d2, and di equals to d2 minus 4mm; and the control signal output end of a touch screen is connected with the control signal input end of an external rotor electric machine, the signal output end of the external rotor electric machine is connected with the signal input end of the touch screen, the loop inspiration port of a respiration loop is communicated with the inspiration end of a disposable anesthetic loop through the external rotor electric machine, and the loop expiration port of the disposable anesthetic loop is communicated with a respiration loop through a dioxide carbon absorption unit. The electric continuous flow device is used in the anesthetic loop systems for children and adults.

Description

technical field [0001] The invention relates to a continuous airflow device for a circulation loop, which belongs to the technical field of anesthesia medical equipment. Background technique [0002] The anesthesia circuits used in pediatric anesthesia centers mostly use semi-open circuits, which are widely used due to their advantages of low resistance, low breathing power consumption, and taking into account both controlled breathing and spontaneous breathing. The flow of fresh air can dry out a child's airway, leading to heat loss and inefficient breathing. In order to solve spontaneous breathing and control breathing, various circuits need to be designed and produced. In the process of surgical anesthesia, the body absorbs and utilizes very little oxygen and volatile anesthetics, and a large amount of unused oxygen and volatile anesthetics are discharged into the atmosphere, wasting precious medical resources and seriously polluting the environment. [0003] Due to the...

AI Technical Summary

Problems solved by technology

[0004] The present invention solves the problem of the semi-open anesthesia circuit used in pediatric anesthesia. The high-flow fresh airflow can make the airway of children dry, heat loss, and respiratory efficiency low. In addition, during the operation anesthesia process, the body absorbs and utilizes very little oxygen and volatile anesthetics. , a large amount of unused oxygen and volatile anesthetics are discharged into the atmosphere, wasting precious medical resources and seriously polluting the environment. Due to the large resistance and high power consumption of the closed circuit of pediatric anesthesia, it can only be used to control breathing, making the airway pressure Problems such as barotrauma and other problems that limit its clinical application can be raised, and then a circular loop electric continuous airflow device is provided.
