Gas humidification bottle capable of automatically supplementing water

Abstract

The invention provides a gas humidification bottle capable of automatically supplementing water. The gas humidification bottle comprises a sealed water storage tank, a multi-path valve block, a heating water box and a pressure balance pipe, wherein the sealed water storage tank, the multi-path valve block and the heating water box are connected into a whole from top to bottom in sequence; the pressure balance pipe is penetrated in the multi-path valve block, the first end of the pressure balance pipe extends into the inner cavity of the sealed water storage tank and is exposed out of the highest water surface of the sealed water storage tank, and the second end of the pressure balance pipe extends into the inner cavity of the heating water box for balancing air pressure in the sealed water storage cavity and the air pressure in the heating water box; the second end of the pressure balance pipe is exposed out of the water surface of the heating water box; and water in the sealed water storage tank automatically supplements water to the heating water box through the water supplementing channel of the multi-path valve block, and otherwise, the water in the sealed water storage tank stops supplementing water into the heating water box through the water supplementing channel of the multi-path valve block under a negative pressure function. The pressure balance pipe is arranged, a pressure difference of two ends of the pressure balance pipe automatically realizes on and off of the water supplementing channel so as to realize automatic water supplementation of the heating water box, and a structure is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of gas humidification, and in particular relates to a self-hydrating gas humidification bottle. Background technique [0002] At present, the medical oxygen humidification bottle on the market is to pass the oxygen from the hospital wall into the normal temperature pure water in the humidification bottle. When the oxygen contacts with the water, bubbles will be generated. In the process of generating bubbles, the oxygen and water are mixed, so that to the purpose of oxygen humidification. However, because it is water at normal temperature, the water content in oxygen after humidification is very low, because the water saturation in oxygen at normal temperature is low, and the humidification effect is not obvious. [0003] In the prior art, heating is often used to increase the amount of gas humidification. Some humidification methods include heating the bottom of the humidification bottle with a heating pl...

Problems solved by technology

[0004] 1. During the heating process, the traditional heating rod must be completely submerged in water for heating, but when the water is consumed, if the water cannot be replenished in time, the heating rod will be exposed to the water surface, and there is a risk of dry burning;

[0005] 2. After the water is heated, hot and humid gas will be generated, and condensed water will be generated quickly when it enters the nasal oxygen tube, and the condensed water will directly enter the patient's nasal cavity, causing the patient to have the risk of choking

[0006] Traditionally, a Chinese patent with the application number CN201320775409.1 discloses an oxygen humidification bottle, including a bottle body, a water inlet pipe, an air inlet pipe, an air outlet pipe, a bottle stopper, a noise reduction pipe, a control chip, a temperature detector, Heating layer and contactor, the bottle stopper is located at the mouth of the bottle body, the water inlet pipe, the air inlet pipe and the air outlet pipe pass through the bottle stopper and are fixed on the bottle stopper, the bottom of the air inlet pipe is connected to the noise reduction pipe, and the top of the air outlet pipe passes the oxygen through the pipe Delivered to the patient, the heating layer is coated on the outside of the bottle, the shape and size of the heating layer are adapted to the bottle, the contactor and the control chip are located on the outer surface of the heating layer, the temperature detector is located in the bottle, and the temperature detector and the contactor are controlled The terminals are respectively connected to the control chip through the control line, the control chip is connected to the power supply, the heating layer is connected to the power supply through the power supply terminal of the contactor, and the oxygen humidification bottle can increase the humidity of oxygen and increase the temperature of oxygen. Similarly, this patent adopts the heating method of the heating layer The generation of humid and hot gas will still inevitably produce condensed water in the nasal oxygen tube, which will bring discomfort to the patient and the risk of choking water. In addition, the patented humidification bottle cannot automatically replenish water, which will inevitably affect the use efficiency
