Background
The humidifying water tank is a device used together with a respiratory humidifying system, and the respiratory humidifying system can be a respirator or other respiratory treatment equipment with the same function.
The humidifying water tank is internally stored with moisture, is usually connected between the breathing machine and the gas conveying pipeline and is used for humidifying the passing gas; if the humidifying water tank is heated, the passing gas can be heated.
When patients have hypoxic respiratory failure, such as ARDS, pneumonia, pulmonary fibrosis, cardiogenic pulmonary edema and other symptoms, high-flow oxygen therapy is needed. During treatment, a patient needs to fix the nasal plug or the breathing mask on the face, and airflow generated by the equipment is heated and humidified by the humidifying water tank assembly and then is conveyed to the patient end.
As shown in fig. 1, the buoy in the existing humidification water tank 1 controls the water in the water tank 1 to be kept at a constant water level all the time when in use, and the buoy plug 2 in the buoy plays a role of opening and closing the falling of water drops. When the water level is low, the buoy sinks, the buoy plug 2 is far away from the thimble 3, so that the water in the water injection pipe 4 drops into the water tank 1 through the thimble 3, and the water level rises. The buoy can float upwards along with the rising of the water level, and when the water level reaches the water level line, the buoy plug 2 can prop against the thimble 3 of the water injection pipe 4 to seal the water injection pipe, so that the water can not continuously drip.
When the humidification water tank is used for adding water, the water adding amount is ensured not to exceed a certain height, otherwise, water enters the gas conveying pipeline due to overflow, the patient is choked, and the life safety of the patient is seriously threatened even. In order to solve the problems, the existing humidification water tank adopts a water locking buoy, the buoy can lock water by means of buoyancy of the buoy, although the overflow problem is solved to a certain extent, the problem that the buoy fails is still caused, people using the product are in sleep or coma, and once the buoy fails to be treated timely, the water level gradually rises to cause the patient to choke and cough, so that danger is generated.
Therefore, how to solve the above-mentioned deficiencies of the prior art is a problem to be solved by the present invention.
