Description

Technical Field

[0001] This utility model relates to the field of ventilators, and in particular to a humidifier tank water level alarm for ventilators. Background Technology

[0002] A ventilator is a medical device used to artificially replace or assist a patient's spontaneous breathing function, especially when the patient is unable to breathe independently or has impaired respiratory function. It improves respiratory function, reduces the work of breathing, and saves or prolongs the patient's life by providing a certain pressure or volume to help the patient achieve effective gas exchange.

[0003] The humidifier is a crucial component of a ventilator system, primarily functioning to humidify and warm the gas output by the ventilator, thereby improving patient comfort and treatment effectiveness. Adding water to the humidifier is generally done manually. The outer wall of the humidifier has water level markings; the standard water level is reached after filling to these markings. However, relying solely on these markings for precise measurement is not sufficiently effective as the warning system is inadequate. If the operator is not paying close attention, it is easy to add too much or too little water.

[0004] Therefore, it is necessary to provide a new humidifier tank water level alarm to solve the above-mentioned technical problems. Utility Model Content

[0008] The second mounting base is fixed to the lower end of the first mounting base, and an alarm structure is provided on the second mounting base;

[0009] The monitoring component includes a liftable slide mounted on a second mounting base, with an infrared generator and a water level probe fixed at the lower end of the slide.

[0010] Preferably, the first mounting base is also provided with a control button for controlling the suction cup pressure.

[0011] Preferably, the alarm structure includes an alarm and three warning lights, which emit green, yellow and red light respectively.

[0012] Preferably, a transmission seat is also fixed on one side of the slide, and a threaded rod is rotatably connected to the second mounting seat. The top of the threaded rod extends above the second mounting seat and is fixed with a knob. The threaded rod passes through the transmission seat and is threadedly connected to it.

[0015] Compared with related technologies, the humidifier tank water level alarm provided by this utility model has the following beneficial effects:

[0016] This utility model provides a humidifier tank water level alarm that can be directly fixed inside the humidifier tank by a suction cup.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 4 This utility model provides a humidifier tank water level alarm, which includes:

[0028] The first mounting base 1 has a fixing structure, which includes a suction cup 11. The suction cup 11 is fixed to the inner wall of the humidification tank by negative pressure adsorption. The first mounting base 1 is also provided with a control button 12 to control the pressure of the suction cup 11.

[0029] The second mounting base 2 is fixed to the lower end of the first mounting base 1, and an alarm structure is provided on the second mounting base 2.

[0030] The monitoring component 3 includes a liftable slide 31 mounted on the second mounting base 2, with an infrared generator 35 and a water level probe 36 fixed at the lower end of the slide 31.

[0031] It should be noted that this device is used for monitoring the water temperature during the filling of the humidification tank;

[0032] The fixing structure includes a suction cup 11 and a control button 12. The suction cup 11 is fixed to the inner wall of the humidification tank by negative pressure, so it can be disassembled after use to achieve multiple uses. After use, it can be disassembled and stored to avoid damage to the device (this fixing structure is a traditional suction cup structure, and its specific operation will not be described in detail here).

[0033] The monitoring component 3 is installed on the second mounting base 2. The water level probe 36 in the monitoring component 3 is the main monitoring structure. At the same time, an infrared generator 35 is also set on the slide base 31. The infrared generator 35 is used for positioning. That is, the infrared light emitted by it should be horizontally pointed to the standard scale line, so as to accurately locate the position of the water level probe 36, which will make the subsequent water injection more accurate.

[0034] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The alarm structure includes an alarm 21 and three warning lights 22, which emit green, yellow and red light respectively.

[0035] Meanwhile, the water level probe 36 includes three detection sections, which are respectively connected to three warning lights 22. The infrared generator 35 corresponds to the uppermost detection section of the water level probe 36 and emits light horizontally pointing towards the standard water level line.

[0036] It should be noted that: the alarm 21 can emit a warning sound to remind the operator, while the warning light 22 emits a warning light. The warning light 22 has three types of light. In the first detection zone when the water level just reaches the lowest position of the water level probe 36, it emits a green light. In this state, the operator raises the water level to the highest position, and water can still be injected. In the second detection zone when the water level rises to the middle position, it emits a yellow light, at which time the water injection speed can be slowed down. In the third detection zone when the water level rises to the highest position, it emits a red light, and water injection can be stopped. Therefore, the warning effect is very obvious.

[0037] In the embodiments of this utility model, please refer to Figure 4 A transmission seat 32 is fixed on one side of the slide 31, and a threaded rod 33 is rotatably connected to the second mounting seat 2. The top of the threaded rod 33 extends to the top of the second mounting seat 2 and is fixed with a knob 34. The threaded rod 33 passes through the transmission seat 32 and is threadedly connected to it.

[0038] It should be noted that when the device is fixed inside the humidification tank, but there is a deviation between the position of the infrared generator 35 and the standard scale line, the knob 34 can be turned to adjust the screw rod 33 to rotate, thereby driving the slide 31 to move in the vertical direction and adjusting the position of the infrared generator 35 to correspond with the standard scale line.

[0039] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0040] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
