[0003] The humidifier tank commonly used in clinical practice only has the water level line marked on it, so medical staff need to pay attention to the water level frequently. Too much water in the humidifier tank can easily cause the water in the tank to flow into the patient's airway along the ventilator pipeline, causing the patient to aspirate, and can also easily lead to respiratory tract infection. At the same time, water entering the ventilator pipeline can easily cause damage to the ventilator. Too little water in the humidifier tank can easily cause the patient's respiratory mucosa to dry out, and the respiratory secretions can become viscous and difficult to discharge, causing blockage.

[0004] The existing ventilator humidification tank on the market is connected to the liquid bottle. The liquid bottle (usually 500 ml, sterile water for injection) is generally fixed on a horizontal bracket. When in use, nursing staff often ignore the water level line of the humidification tank, causing the humidifier to dry out. When refilling water, the staff needs to manually operate it, which requires manpower, consumes manpower and time, and has a low level of automation, which cannot meet the needs of modern medical development.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1 and Figure 6, an embodiment provided by the utility model: an automatic regulating water-adding device for a humidifier tank of a ventilator, comprising a heating base 1 for heating the sterilized water inside the humidifier tank 2, the sterilized water will evaporate into water vapor after being heated, a bottom plate 3 is placed on the upper surface of the heating base 1, the upper surface of the bottom plate 3 is fixedly connected with the humidifier tank 2, the upper surface of the humidifier tank 2 is provided with a connecting component, the connecting component can maintain air circulation, the upper surface of the humidifier tank 2 is provided with a fixing component, the fixing component can fix the infusion tube 52 on the humidifier tank 2, the interior of the humidifier tank 2 is provided with an adjusting component, the adjusting component can control the amount of sterilized water inside the humidifier tank 2, the adjusting component comprises a connector 61, the connector 61 is configured as a flat-topped cone, the lower surface of the connector 61 is penetrated and slidably connected with a hollow tube 62, the lower surface of the hollow tube 62 is penetrated and slidably connected with a round rod 63, and the round rod 63 slides up and down along the lower surface of the hollow tube 62.

[0036] Reference Figure 4 - Figure 6 The lower surface of the round rod 63 is fixedly connected with a float mold 64, which is light and will float on the sterile water. When the amount of water inside the humidification tank 2 increases, the float mold 64 will float upward. The upper surface of the hollow tube 62 is fixedly connected with a rubber block 65, which can play a sealing role. The fixed component includes a connecting tube 51. The opening area of ​​the lower surface of the connecting tube 51 is smaller than the area of ​​the upper surface of the rubber block 65. The upper surface of the rubber block 65 is arc-shaped and can be tightly attached to the opening of the lower surface of the connecting tube 51. When tightly attached, the connecting tube 51 cannot discharge the sterile water. The outer wall of the connecting tube 51 is threadedly connected with an infusion tube 52, and a threaded groove is provided on the inner wall of the bottom end of the infusion tube 52 501, the outer wall at the top of the connecting tube 51 is set to be threaded, and fits tightly with the thread groove 501, and there is sealant on the thread to maintain the tightness of the connection and prevent the sterilized water from seeping out from the gap. The middle section of the infusion tube 52 is provided with an infusion switch 53. The infusion switch 53 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The upper surface of the infusion tube 52 is provided with a sterile water tank 54 for storing sterilized water. The upper surface of the sterile water tank 54 is fixedly connected with a hook 55, and the hook 55 can fix the sterile water tank 54 on a horizontal bracket or an IV stand.

[0037] Reference Figure 3 , Figure 6 and Figure 7 The connecting tube 51 passes through and is fixedly connected to the upper surface of the humidification tank 2. The upper surface of the connecting head 61 is fixedly connected to the lower surface of the connecting tube 51. A through groove 601 is provided on the lower surface of the connecting head 61. Sterilized water can enter the humidification tank 2 through the through groove 601. The rubber block 65 is made of rubber material, which can ensure the tightness of the rubber block 65 when it is close to the lower surface of the connecting tube 51.

[0038] Reference Figure 1 The connecting component includes an air inlet pipe 41 for air intake. The air to be humidified will enter the humidification tank 2 from the air inlet pipe 41. An air outlet pipe 42 is passed through and fixedly connected to the upper surface of the humidification tank 2. The humidified air will be discharged from the air outlet pipe 42. The air inlet pipe 41 passes through and is fixedly connected to the upper surface of the humidification tank 2.

[0039] Working principle: When the ventilator is working, the heating base 1 will heat the sterilized water in the humidification tank 2, and the water will evaporate into water vapor and follow the gas entering the humidification tank 2 from the air inlet pipe 41, and be discharged into the pipeline from the air outlet pipe 42, and enter the patient's trachea through the pipeline, playing the role of humidifying the airway, and the two types of sterilized water in the humidification tank will also be reduced.

[0040] As the amount of sterilized water inside the humidification tank 2 decreases, the water level will drop, and the float mold 64 will move downward under the influence of its own gravity, and will drive the round rod 63, the hollow tube 62 and the rubber block 65 to move downward. The rubber block 65 moving downward will release the obstruction to the connecting tube 51, and the sterilized water in the sterilized water tank 54 will flow into the humidification tank 2 through the infusion tube 52 and the connecting tube 51, ensuring that there is sufficient sterilized water inside the humidification tank 2, thereby solving the problem of the device drying up due to nursing staff forgetting to add water, and there is no need for nursing staff to add water specifically, thus reducing time consumption.

[0041] As the amount of sterilized water increases, the water level will rise, and the float mold 64 will move upward with the rising water level, driving the round rod 63 to move upward and retract into the hollow tube 62. When the float mold 64 contacts the hollow tube 62, it will also drive the hollow tube 62 and the rubber block 65 to move upward. The upward moving rubber block 65 will block the lower surface of the connecting tube 51, and the sterilized water cannot enter the humidification tank 2 through the infusion tube 52 and the infusion tube 52, ensuring that the amount of sterilized water in the humidification tank 2 will not be too much, solving the problem that too much sterilized water in the humidification tank 2 causes the sterilized water to enter the airway along the pipeline, causing the patient to aspirate and easily cause the patient's respiratory tract infection, and solving the problem that too much sterilized water enters the ventilator and causes damage to the ventilator.

[0042] When connecting the connecting tube 51, simply align the threaded end of the connecting tube 51 with the thread groove 501 at the bottom of the infusion tube 52 and screw it on. The connecting tube 51 will be fixed on the infusion tube 52 under the action of the thread and the thread groove 501, and will not slide easily, making it easy to install.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
