Purifying and filtering device used for humidifying airway of tracheotomy patient

Abstract

The invention discloses a purifying and filtering device used for humidifying an airway of a tracheotomy patient. The purifying and filtering device comprises a mixing pipe, wherein a connector is arranged at each of two ends of the mixing pipe; a valve bin is arranged above the mixing pipe; a through pipe is arranged at the central part of the bottom end of the valve bin; the bottom end of the through pipe communicates with the interior of the mixing pipe; a buffering piece is arranged in the through pipe; four groups of supporting rods are arranged at the outer side of the bottom end of thebuffering piece; the supporting rods are fixed to the inner wall of the through pipe; a connecting pipe is arranged at the central part of the top end of the valve bin; and the outer side of the top end of the connecting pipe is connected with a purifying pipe in a sleeved mode. According to the invention, particulate matters in water mist are intercepted; the cleaning degree of the water mist entering oxygen is greatly improved; meanwhile, dismounting and mounting are easy and convenient; and the long-acting cleaning and purifying effects of the purifying and filtering device are effectivelyguaranteed.

Description

technical field [0001] The invention relates to the technical field of airway humidification, in particular to a purification filter device used for airway humidification of patients with tracheotomy. Background technique [0002] For the needs of treatment, the trachea of ​​some patients needs to be incised, and the trachea after incision needs to be airway humidified. Airway humidification refers to the use of humidifiers or other devices to disperse the solution into fine particles to increase the temperature and humidity in the inhaled gas, so that the respiratory tract and lungs can inhale gas with sufficient moisture and appropriate temperature to achieve humidified gas. It is a physical therapy to improve the mucous membrane of the tract, maintain the motility of cilia, dilute sputum and clear out the function. [0003] However, in the prior art, in the process of airway humidification, the water mist output by the humidifier contains fine particles, which will not o...
