Description

Technical Field

[0001] The utility model relates to the technical field of humidification tanks, in particular to a water injection device for a humidification tank. Background Art

[0002] The ventilator is equipped with a humidifier tank. The main function of the humidifier tank is to add necessary moisture to the respiratory airflow to ensure that the patient obtains appropriate humidity when inhaling air, which is essential for protecting the patient's respiratory mucosa and improving breathing comfort. However, as the treatment time increases, the amount of water in the humidifier tank will gradually decrease. Therefore, it is necessary to regularly add pure water to the humidifier tank to maintain its humidification function. At present, a conventional humidifier tank is provided with a joint on the top. The humidifier tank is replenished by opening the end cover of the joint and then injecting water into the humidifier tank with a syringe to complete the hydration operation.

[0003] However, repeatedly opening and closing the connector end cap can easily cause the end cap to loosen, which not only affects the sealing performance of the humidification tank, but also makes it easier for external contaminants to enter the tank, thereby increasing the risk of infection for patients. Secondly, when the end cap is open, before the syringe is docked with the connector, the connector is in an open state, which also provides a path for bacteria and other microorganisms to enter the humidification tank, further exacerbating the contamination problem.

[0021] 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.

[0022] The utility model provides a humidification tank water injection device, such as Figure 1-Figure 3 As shown, it includes a humidification tank 1, a syringe 3, a connecting component 2 and a valve component 4.

[0024] The connecting component 2 includes a connecting tube 21, both ends of which are respectively connected to the liquid adding interface 12 and the syringe 3. Water is injected into the connecting component 2 through the syringe 3 and then enters the humidification tank 1 to perform a water replenishment operation.

[0025] Preferably, a joint 22 is provided at the top of the connecting tube 21, an inner gasket 221 is installed on the inner wall of the joint 22, and a lower gasket 222 is installed on the bottom of the inner wall of the joint 22, the injection end of the syringe 3 can be inserted into the joint 22, so as to facilitate the tight connection between the joint 22 and the syringe 3, an outer gasket 24 is provided on the outer side of the bottom end of the connecting tube 21, and the bottom end of the connecting tube 21 can be inserted into the liquid filling interface 12, so as to facilitate the tight connection between the connecting tube 21 and the liquid filling interface 12.

[0026] Furthermore, a filter screen 23 is installed inside the connecting pipe 21 to play a filtering effect and prevent impurities from entering the humidification tank 1.

[0027] Preferably, the connecting pipe 21 is made of a transparent glass material to facilitate observation of the water replenishment situation.

[0028] The valve assembly 4 includes a connecting rod 412, which is rotatably inserted into one side of the connecting pipe 21. A valve plate 41 is provided at one end of the connecting rod 412 located in the connecting pipe 21, and a knob 42 is provided at the other end of the connecting rod 412.
