[0002] The ventilator is a commonly used device in the respiratory department. Its function is to provide oxygen to patients to maintain normal breathing. The humidifier is an important accessory of the ventilator. Its main function is to heat and humidify the inhaled air so that the patient's airway remains moist. The structure of the ventilator humidifier mainly includes a water tank and a heating device, which are then connected to the ventilator through a pipe. The commonly used ventilator humidifiers are simple in structure. Water is generally added and the water level is controlled manually, which requires users to pay attention at all times during use, resulting in excessive energy consumption. In addition, the amount of water added during use often deviates due to the experience of the personnel, resulting in large disturbances during use. How to achieve liquid level control and timely alarm when using the ventilator humidifier so that users can get feedback in a timely manner has become a technical problem that needs to be solved.

The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the scope of protection of the utility model.

[0040] (Example 1)

[0041] like Figure 1-6 As shown, a ventilator humidification tank water level alarm device comprises a tank body 101, a base 102 arranged at the bottom of the tank body 101, and a sealing cover 103 movably plugged into the top of the base 102, wherein a first connecting pipe 2011 is vertically connected to the inside of the tank body 101, and a second connecting pipe 2012 is vertically connected to the first connecting pipe 2011 and passes through the tank body 101, a floating ball 2021 is slidably connected to the inner wall of the second connecting pipe 2012, a resistance ring 20222 is fixedly connected to the inner wall of the second connecting pipe 2012, and a sliding plug 20221 is slidably connected, a connecting rod 20223 is fixed to the sliding plug 20221, a conductive rod 20224 is arranged on the connecting rod 20223, the conductive rod 20224 is in sliding contact with the inner wall of the resistance ring 20222, and an ammeter is connected in series in the power supply circuit of the resistance ring 20222, and the ammeter is connected to an alarm.

[0042] The height of the float 2021 changes with the liquid level in the tank 101. When the height of the float 2021 increases, the air pressure in the first connecting tube 2011 and the second connecting tube 2012 gradually increases, pushing the sliding plug 20221. The sliding plug 20221 drives the connecting rod 20223 and the conductive rod 20224 to slide. At this time, the resistance value of the resistance ring 20222 decreases, and the ammeter detects that the current gradually increases until it exceeds the set range. The ammeter transmits a signal to the alarm, and the alarm sounds an alarm to remind medical staff. Conversely, when the ammeter detects that the current is too small, it transmits a signal to the alarm, and the alarm still sounds an alarm to remind medical staff.

[0043] The float 2021 is arranged to drive the sliding plug 20221, the connecting rod 20223 and the conductive rod 20224 to move and change the resistance value of the resistor ring 20222, thereby changing the current. After the ammeter measures the change in current, the alarm sounds an alarm to prompt medical staff to increase or decrease the amount of liquid in the tank 101, thereby improving the accuracy and continuity of observation and avoiding large errors in observation results caused by manual subjective observation.

[0044] In this embodiment, a rubber sealing ring is provided between the top of the base 102 and the tank body 101 to increase the sealing performance of the connection between the tank body 101 and the base 102 and prevent the liquid from flowing out.

[0045] In this embodiment, a baffle 20111 is fixedly connected to the bottom end of the second connecting tube 2012 , and a liquid leakage groove 20112 is opened on the surface of the baffle 20111 .

[0046] The baffle 20111 can prevent the float 2021 from falling out of the first connecting pipe 2011 , thereby ensuring the stability of the float 2021 .

[0047] In this embodiment, a heating wire 4 is provided inside the tank body 101 , and the heating wire 4 and the resistance ring 20222 are connected in series in the same circuit. The temperature of the liquid can be adjusted by providing the heating wire 4 .

[0048] (Example 2)

[0049] A humidifier tank water level alarm device for a ventilator, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 2-4 As shown:

[0050] A spring 20227 is sleeved on the outer wall of the conductive rod 20224 , one end of the spring 20227 is fixedly connected to the connecting rod 20223 , and the other end of the spring 20227 is fixedly connected to a limit ring 20226 , and the limit ring 20226 is fixedly connected to the side of the conductive rod 20224 close to the resistance ring 20222 .

[0051] A ball 20225 is disposed at one end of the conductive rod 20224 close to the resistance ring 20222 , and the ball 20225 rolls and fits with the inner wall of the resistance ring 20222 .

[0052] The sliding plug 20221 drives the connecting rod 20223, the conductive rod 20224 and the ball 20225 to slide back and forth on the inner wall of the resistance ring 20222. During the sliding process, the spring 20227 undergoes elastic deformation.

[0053] By providing the spring 20227 and the ball 20225, a buffer can be provided, the friction and wear between the resistance ring 20222 and the conductive rod 20224 can be reduced, and the working efficiency and performance stability of the resistor can be improved.

[0054] During work, after the medical staff assembles the clean tank body 101, the base 102, and the sealing cover 103, they turn on the heating wire 4 to keep the liquid warm. When the liquid level in the tank body 101 is too high, the float 2021 moves up with the liquid level, and the air pressure in the cavity of the first connecting tube 2011 and the second connecting tube 2012 gradually increases, pushing the sliding plug 20221 toward the first connecting tube 2011, and the sliding plug 20221 drives the connecting rod 20223 and the conductive rod 20224 to slide. At this time, the resistance value of the resistance ring 20222 becomes smaller, and the ammeter detects that the current gradually increases until it exceeds the set range. The ammeter transmits a signal to the alarm, and the alarm sounds an alarm to remind the medical staff to reduce the amount of liquid. Conversely, when the liquid level in the tank body 101 is too low, the ammeter detects that the current is too small and transmits a signal to the alarm, and the alarm still sounds an alarm to remind the medical staff to increase the amount of liquid.

[0055] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
