Description

A closed sputum suction tube

technical field

The utility model relates to a closed sputum suction tube.

Background technique

Existing sputum suction operation: endotracheal tube: enter the lungs of the child for oxygen supply, the biggest complication: respiratory-related pneumonia; 2. Y-shaped connector: connected to the endotracheal tube, one end connected to the ventilator circuit: oxygen supply, the other end Connecting a closed suction tube: to clean up respiratory secretions, that is, suction; 3. Closed suction tube: one of the measures to prevent ventilator-associated pneumonia, used to clean up respiratory secretions. It consists of four parts: suction tube, plastic film outside the suction tube, negative pressure suction head and flushing suction tube connector; 4. Clinical use: when the respiratory tract of a child has secretions, the respiratory tract needs to be cleaned immediately, and the closed type is used. Suction tube, put the suction tube into the endotracheal tube, press the negative pressure suction head to suck out the secretions, and then flush the suction tube with water from the joint of the flushing suction tube.

Disadvantages of the existing operation: 1. Flushing Clinically, a syringe is often used to flush the suction tube, which is replaced every 4 hours. Each flush requires a tube of water, and the nurse needs to repeatedly draw out the saline from the large container bottle, which is time-consuming and convenient. Poor performance; secondly, more consumables need to be prepared for each flushing. 2. Nosocomial infection and infection problems: Due to the needs of the patient's condition, the patient needs to do fiberoptic bronchoscopy and respiratory sputum culture. The entrance for operation or collection is the closed suction tube and the Y-shaped interface, and the closed suction needs to be disconnected Tube fiberoptic bronchoscopy or the collection of sputum culture in the airway, every time it is disconnected, part of the gas entering or expelled by the child will overflow from the disconnection, especially for patients with respiratory infectious diseases, resulting in the spread of the disease and harm Safety of medical staff and other patients. 3. Patient safety: For patients with severe pulmonary infection, such as children with ARDS, pulmonary hemorrhage, and pulmonary edema, it takes a long time to perform fiberoptic bronchoscopy, and disconnecting the closed suction tube will cause gas to overflow, resulting in tidal air Reduced blood pressure and lung pressure will aggravate pulmonary hemorrhage and exudation in children, leading to safety problems in children.
