Description

Technical Field

[0001] This application relates to the field of humidification liquid preparation technology, and in particular to a humidification liquid concentration ratio device. Background Technology

[0002] Humidifying fluid is a liquid used to increase the humidity of inhaled air and lubricate the bronchial walls. It plays a crucial role in airway management by keeping the respiratory tract moist, thinning sputum, promoting sputum expectoration, and maintaining normal respiratory function, making it important in the medical field. Common humidifying fluids include sodium chloride solution, sodium bicarbonate solution, and distilled water. Except for distilled water, most are compound solutions, therefore, the concentration of humidifying fluid needs to be controlled. In the preparation process, humidifying fluid is usually produced through manual proportioning; however, manual proportioning has poor accuracy and cannot effectively improve the precision of humidifying fluid concentration, thus requiring improvement. Utility Model Content

[0003] To improve the accuracy of humidification solution concentration ratio, this application provides a humidification solution concentration ratio device.

[0004] The humidification liquid concentration proportioning device provided in this application adopts the following technical solution:

[0005] A humidification solution concentration proportioning device includes a proportioning tank with a bottom cylinder inside. The bottom cylinder includes a body and a cover. A first weight sensor is installed inside the body, and a proportioning container is placed on the surface of the first weight sensor. A water storage tank and a solute storage tank are located above the bottom cylinder. A drain pipe is connected to the bottom wall of the water storage tank, and a discharge pipe is installed on the bottom wall of the solute storage tank. A transfer platform is installed at the end of the discharge pipe away from the solute storage tank. The transfer platform is rotatably connected to the inner wall of the proportioning tank. A second weight sensor is installed inside the transfer platform. An inlet for solute and water to enter the proportioning container is opened at the top of the cover. A control module is installed on the outer wall of the proportioning tank. Solenoid valves are installed on both the drain pipe and the discharge pipe. The first weight sensor, the second weight sensor, and the solenoid valves are all communicatively connected to the control module.

[0006] By adopting the above technical solution, when it is necessary to prepare a humidification solution, the required solute is added to the solute storage tank, the solenoid valve on the drain pipe is opened, and water enters the preparation tank through the drain pipe. The first weight sensor weighs the water and transmits the weight data to the control module. The control module calculates the required solute mass based on the concentration of the humidification solution, the solenoid valve on the discharge pipe is opened, and the solute is poured onto the surface of the transfer platform. When the solute mass reaches the preset value of the second weight sensor, the solenoid valve is closed, and the control module drives the transfer platform to rotate, pouring the solute into the preparation tank. In this way, a humidification solution of the target concentration can be prepared, improving the accuracy of the preparation.

[0007] Preferably, the surface of the transfer platform has a receiving cavity, the second weight sensor is disposed in the receiving cavity, and a carrier film is also disposed in the receiving cavity. The carrier film is located above the second weight sensor, and the bottom wall of the carrier film is attached to the surface of the second weight sensor.

[0008] By adopting the above technical solution, the accuracy of solute mass measurement can be effectively improved, thereby making the concentration ratio of the humidification solution more accurate.

[0009] Preferably, the cylinder cover is provided with a connecting flange for fixing it to the cylinder body.

[0010] By adopting the above technical solution, the connection flange can effectively improve the ease of connection between the cylinder cover and the cylinder body.

[0011] Preferably, the inner wall of the cylinder is provided with a plurality of positioning pins, one end of which is bent toward the cylinder cover, and the peripheral wall of the opening of the mixing tank is provided with a connecting edge, and the bottom wall of the connecting edge is provided with a plurality of positioning holes for the positioning pins to be inserted.

[0012] By adopting the above technical solution, the positioning pin can facilitate the precise installation of the mixing tank, thereby reducing the shaking of the mixing tank during the mixing process, reducing the leakage of the solution, and further improving the accuracy of the humidification solution mixing.

[0013] Preferably, the surface of the cylinder cover is provided with a rotating component, the output shaft of the rotating component passes through the cylinder cover, the output shaft of the rotating component is connected to a stirring shaft, and the peripheral wall of the stirring shaft is provided with a plurality of stirring blades.

[0014] By adopting the above technical solution and setting up rotating parts and stirring shaft, the mixing speed of solute and water can be improved, thereby improving the proportioning efficiency of the humidified solution.

[0015] Preferably, the inner wall of the mixing tank is provided with a concentration detection module, and the concentration detection module is communicatively connected to the control module.

[0016] By adopting the above technical solution, a concentration detection module can be set up to detect the solution obtained by mixing, so as to ensure that the concentration of the humidification solution is within the target range.

[0017] Preferably, a guide pipe is provided at the input port, and the end of the guide pipe away from the bottom cylinder is flared.

[0018] By adopting the above technical solution, the flow guide pipe can ensure that both solute and water can accurately enter the mixing tank, thereby ensuring that the precise amount of solute and water can be mixed to form a wetted solution of the target concentration, thus improving the accuracy of the mixing ratio.

[0019] Preferably, the drain pipe has a purging device connected to its side wall.

[0020] By adopting the above technical solution, connecting the drain pipe to the purging device allows all the water in the drain pipe to enter the mixing tank, thereby enabling the first weight sensor to accurately detect the mass of all the water participating in the mixing. This prevents the water that has not been discharged from the drain pipe from gradually entering the mixing tank after the first weight sensor has measured the weight, thus avoiding the problem of affecting the accuracy of the humidification solution concentration ratio.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When it is necessary to prepare a humidification solution, add the required solute to the solute storage tank, open the solenoid valve on the drain pipe, and water enters the mixing tank through the drain pipe. The first weight sensor weighs the water and transmits the weight data to the control module. The control module calculates the required solute mass based on the concentration of the humidification solution. The solenoid valve on the discharge pipe opens, and the solute is poured onto the surface of the transfer platform. When the solute mass reaches the preset value of the second weight sensor, the solenoid valve closes, and the control module drives the transfer platform to rotate, pouring the solute into the mixing tank. This allows for the preparation of a humidification solution with the target concentration, improving the accuracy of the preparation.

[0023] 2. The addition of a rotating component and a stirring shaft can increase the mixing speed of the solute and water, thereby improving the efficiency of the wetted solution preparation. Attached Figure Description
