Vacuum-controlled aspiration catheter - a device used to remove biological fluids from the upper respiratory tract through an endotracheal or tracheostomy tube. The main area of application is for patients in intensive care units and intensive care units undergoing mechanical ventilation, as well as patients with severe respiratory diseases. The aspiration catheter has a design that allows for efficient and rapid suction of secretions from cavities, bronchi, lungs, trachea, pharynx, and restores nasal and oral breathing necessary for better oxygen supply to organs. Also, aspiration catheters with vacuum control can be used during open surgeries to remove fluids from cavities and wounds and maintain the cleanliness and dryness of the operating field. Structurally, the aspiration tracheobronchial catheter with vacuum control consists of two parts: a body in the form of a tube made of transparent plastic material and a plastic connector that allows it to be connected to a vacuum aspirator. The tube has a small diameter so that it can be placed in an endotracheal or tracheostomy tube, it usually reaches 40-56 cm (16-22 inches). Vacuum control is a device in the form of a hole in the connector that allows you to control and regulate the intensity of fluid suction using your thumb. The characteristics of aspiration catheters make them effective and convenient to operate: due to universal connectors, they are compatible with all models of vacuum aspirators; in the connector area, additional stiffening edges are located so that the connection with the vacuum aspirator is more reliable; are equipped with color coding of size to speed up the procedure for selecting size, taking into account the patient's age and complexion; The transparent material of both the tube and the connector allows you to control the correct installation and operation of the system, the characteristics of the separated liquid; made of thermoplastic non-toxic polyvinyl chloride, which softens from body temperature and becomes even more plastic and safe; along its entire length, there is an X-ray contrast band to monitor the patient's body position; due to the ergonomic shape of the handle, the instrument lies comfortably in the hand, which ensures atraumatic and gentle insertion and use; the soft material and rounded end make aspiration a comfortable procedure for the patient without the risk of sucking and injuring the mucous and soft membranes
