Automatic suction and cleaning device for secretion of upper portion of airbag of trachea cannula

Abstract

The invention relates to an automatic suction and cleaning device for secretion of the upper portion of an airbag of a trachea cannula. The device comprises a shell, an infusion pump, a secretion storage tank, a cleaning liquid storage tank and a control circuit board. An inlet pipe and an outlet pipe are arranged on the infusion pump. The device is characterized in that an infusion pipe and a hydraulic filling liquid level meter are arranged in the secretion storage tank, the infusion pipe is communicated with the outlet pipe through a first single-way valve, and a cleaning pipe and an emptyliquid level meter are arranged in the cleaning liquid storage tank; the lower end of the cleaning pipe is located at the bottom of the cleaning liquid storage tank, the upper end of the cleaning pipeis communicated with the outlet pipe through a second single-way valve, and during use, the inlet pipe is communicated with a suction pipe on the trachea cannula. According to the suction and cleaning device, secretion and backflow residues in the trachea of a patient can be automatically sucked out, cleaning liquid can also be used for cleaning the suction pipe and the upper portion of the airbag of the trachea cannula of the patient, complications, such as pneumonia and asphyxia, of the patient can be effectively avoided, and the automatic suction and cleaning device has the obvious advantages and is suitable for application and popularization.

Description

technical field [0001] The invention relates to a suction and cleaning device, in particular to an automatic suction and cleaning device for secretions above a tracheal intubation air bag. Background technique [0002] For patients with respiratory dysfunction and during cardiopulmonary resuscitation, it is necessary to insert a tracheal tube into the patient's trachea, and use the tracheal tube to connect to a ventilator for a long time to assist the patient to breathe. In order to fix the endotracheal tube and ensure no gas leakage during mechanical ventilation, the air bag under the endotracheal tube needs to be inflated for a long time and attached to a fixed position on the tracheal wall. However, as time goes by, the upper airway secretions stagnant or refluxed food residues will form a secretion "effusion lake" above the endotracheal intubation balloon. The flow of food residues flows down into the trachea, leading to pneumonia and aggravated respiratory failure, and...
