Multifunctional medical breathing heat and moisture exchanger

Abstract

The invention discloses a multifunctional medical breathing heat and moisture exchanger. The multifunctional medical breathing heat and moisture exchanger comprises a breathing machine air inlet, a breathing machine extension pipe connector, a plurality of fixed bulges, an air particle filtering material, a heat preservation and moisture retention macromolecule material, a liquid outlet cover, a sputum secretion collecting cavity, two stretchable hoses, a liquid outlet and a filtering cavity, wherein the breathing machine air inlet is connected to the filtering cavity through the stretchable hoses; the fixed bulges are arranged in the filtering cavity; the air particle filtering material and the heat preservation and moisture retention macromolecule material are respectively arranged in the filtering cavity through the fixed bulges; the rear end of the filtering cavity is connected to the front end of the sputum secretion collecting cavity; the rear end of the sputum secretion collecting cavity is connected to the breathing machine extension pipe connector through the stretchable hoses; the liquid outlet is formed in the sputum secretion collecting cavity; the liquid outlet cover covers the liquid outlet. The multifunctional medical breathing heat and moisture exchanger has an effect of filtering air particles and can realize a constant-temperature moisture retention effect so as to protect normal exertion of functions of cilia and glands of respiratory mucosa.

Description

technical field [0001] The invention relates to a medical device, in particular to a multifunctional medical respiratory moisture heat exchanger. Background technique [0002] Ventilators and anesthesia machines supply dry and low-temperature gas to critically ill and tracheotomized patients. After tracheal intubation or surgery, due to the rerouting of the respiratory tract, the normal respiratory tract loses its ability to adjust the temperature and humidity of the inhaled gas. Heated and humidified gas can easily lead to viscous bronchial secretions, difficult to cough up sputum, aggravate airway blockage, increase the peak airway pressure, cause the patient's blood oxygen saturation to drop, and fail to achieve the expected curative effect of the ventilator. At the same time, bacteria Can not be effectively filtered at the same time to cause lung and respiratory infections. [0003] The existing humidification and warming method for the pipeline of the ventilator is t...

Problems solved by technology

Its shortcoming is that the humidification tank needs to be used in conjunction with various equipment and requires loss of filter paper consumables. When using it, the heating temperature in the airway needs to be set in advance, but it cannot accurately meet the ideal temperature requirements of the patient.

When the humidification tank is humidified, the humidity in the airway is high. When the temperature differen
