Intermittent negative-pressure sputum suction device for child patients suffering from congenital esophageal atresia, and using method of intermittent negative-pressure sputum suction device

Abstract

The invention discloses an intermittent negative-pressure sputum suction device for a child patient with congenital esophageal atresia, and a using method of the intermittent negative-pressure sputumsuction device. The device comprises a liquid storage bottle, a bottle cap, a processor, an alarm module, an electromagnetic valve control module, an electromagnetic valve, a battery, an AC / DC conversion module, a working mode knob, a touch screen, a liquid level sensor, a negative pressure interface, an air pressure adjusting knob and a barometer, wherein the liquid storage bottle is of a hollowcylinder structure with an opening in the upper end, a threaded opening matched with the bottle cap is formed in the upper end face of the liquid storage bottle, a bottle cap negative pressure pipe isarranged at the circle center of the bottle cap in a penetrating mode and extends into an inner cavity of the liquid storage bottle, the upper end of the bottle cap negative pressure pipe is connected with the output end of the electromagnetic valve, the input end of the electromagnetic valve is connected with the negative pressure interface, the air pressure adjusting knob and the barometer arearranged on the negative pressure interface, and a sputum suction tube interface connected with a sputum suction tube is arranged on the side face of the bottle cap. The intermittent negative pressuresputum suction device for the child patient with the congenital esophageal atresia is simple in structure and convenient to use.

Description

technical field

[0001] The invention belongs to the technical field of negative pressure sputum suction, and in particular relates to an intermittent negative pressure sputum suction device for children with congenital esophageal atresia and a use method thereof. Background technique

[0002] Congenital esophageal atresia and tracheoesophageal fistula are collectively referred to as congenital esophageal atresia, which is a serious developmental malformation of the digestive tract in the neonatal period. The main manifestations are vomiting, bruising, coughing, and dyspnea when the infant is breastfeeding. This type of infant occurs immediately after birth and will be sent to the Intensive Care Unit (hereinafter referred to as ICU) for rescue. Because such infants will frequently cough and increase oral and nasal secretions, frequent airway management and sputum suction operations are required for such infants, otherwise, the infants will suffocate due to excessive oral and ...
