Description

Humidification tank Technical Field The present utility model relates to the field of medical auxiliary devices, and in particular to a humidification tank for providing humidified gas to a patient. Background In the medical field, a medical humidification tank is an important device matched with a humidification heater for use, and the main function of the medical humidification tank is to heat and humidify dry gas and then convey the dry gas to a patient. The process can effectively reduce the stimulation of dry gas to the respiratory tract mucous membrane of a patient, protect the integrity of the respiratory tract mucous membrane, moisten alveoli and enhance the activity of the alveoli, thereby promoting gas exchange and improving the respiratory comfort and the treatment effect of the patient. The working principle of the humidification tank is based on the automatic control of the liquid. Liquid is injected into the tank body through the water inlet pipe, and when the liquid reaches a certain amount, the buoy floats upwards to block the liquid inlet, so that the excessive injection of the liquid is prevented. The liquid in the tank body evaporates under the heating action of the humidifying heater, and the generated humidifying gas is mixed with the gas delivered to the patient through the gas outlet. The liquid level descends along with continuous evaporation of the liquid in the tank body, the buoy descends along with the liquid level, and the blocking of the liquid inlet is loosened, so that the water inlet pipe continuously injects the liquid into the tank body, automatic control of the liquid amount in the tank body is realized, and the humidification tank is ensured to continuously and stably provide proper humidification gas for patients. The humidifying tanks on the market at present have some problems in the design and use process. The common humidifying tank adopts an independent small buoy and large buoy structure design with an outer sleeve, and the liquid inlet is plugged through floating of the buoy to control the liquid inlet amount. However, in unstable environments (e.g., in ambulances), the small buoy may become stuck, resulting in excessive filling, which may affect the safe use of the device. In addition, the part of the humidifying tank adopts a floating body capable of moving up and down along the height direction, and the liquid injection pipe orifice is plugged by floating up and moving up through the floating body, so that the effect of limiting liquid injection when the water is full and automatically supplementing liquid when the liquid is insufficient is realized. However, the design only adopts the top of the floating body to seal the bottom of the liquid injection pipe orifice, the sealing effect is poor, the leakage phenomenon is easy to occur, the independent small buoy floats on the liquid in the tank body in a suspended manner, the guide pipeline is perpendicular to the bottom surface of the tank body, and when the device is used in a shaking environment, the small buoy can be blocked in the guide pipeline, so that the liquid inlet cannot be effectively sealed. Disclosure of Invention The medical humidification tank solves the problems that a buoy is easy to be clamped, the sealing effect is poor and leakage occurs when the humidification tank is used in an unstable environment in the prior art, can control liquid inlet amount stably and reliably in various environments, and ensures safe use of equipment.
