Automatic water adding humidification tank for respirator heating humidifier

Abstract

The invention relates to an automatic water adding humidification tank for a respirator heating humidifier. The automatic water adding humidification tank comprises a tank body, and a gas inlet and agas outlet are formed in the top end of the tank body; a fixing mechanism is arranged in the tank body; a guide disc and a floating ball are sequentially hinged to the fixing mechanism; a sealing valve is arranged on the guide disc; a transmission rod is arranged between the floating ball and the guide disc; a water inlet is also formed in the position, over the sealing valve, on the tank body; and the water inlet is matched with the sealing valve. The automatic water adding humidification tank has the advantages that two-time sealing can be carried out, that is, when the water line reaches the floating ball, the guide disc and the floating ball act jointly for the first time to seal the water inlet, when the water level rises to the upper end of the floating ball due to other external reasons, the water inlet can further be sealed for the second time through the guide disc, and the double-sealing function is achieved; and in addition, the guide disc can provide an optimized gas flow direction for gas flowing through the humidification tank, and the function of enhancing the gas humidifying effect is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic water-filling humidification tank for a ventilator heating humidifier. Background technique [0002] Respiratory assistance equipment such as ventilators or respiratory humidification therapy instruments for treating patients with respiratory diseases generally include heating and humidifying devices. The ventilator heating humidifier is used to heat the dry gas delivered to the patient during the ventilator treatment process. Humidification device. The automatic water-filling humidification tank matched with the heating humidifier has gradually been popularized and applied in clinic due to its advantages of reducing nursing workload, reducing ventilator-associated pneumonia and simple operation. [0003] However, there are the following defects and deficiencies in the automatic water-filling humidification tank for the ventilator heating humidifier in the p...

AI Technical Summary

Problems solved by technology

However, there is no corresponding disclosure about a technical solution that has double safety limit switches to control the automatic water filling level of the humidification tank used for heating the humidifier of the ventilator, and can optimize the gas flow direction in the humidification tank and enhance the humidification effect.

[0008] To sum up, there is an urgent need for an automatic water filling humidification tank with double safety limit switches to control the automatic water filling level of the humidification tank used for ventilator heating humidifier, and can optimize the gas flow direction in the humidification tank, and about this A kind of automatic water adding humidification tank has not been reported yet
