Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an airway humidification device. Background Art

[0002] Airway humidification devices play an indispensable role in the field of healthcare, especially in long-term oxygen therapy, respiratory support and anesthesia management. During natural breathing, the respiratory system can effectively humidify and regulate the inhaled air through the regulation of the nasal cavity, providing a suitable climate for the lungs. Therefore, airway humidification devices have become a necessary component to ensure normal breathing of patients, and by adding an appropriate amount of moisture to the transported gas, the purpose of protecting the respiratory tract and promoting respiratory health is achieved.

[0003] Although airway humidification devices have important functional value, existing products often encounter the problem of droplets condensing in the mask and overflowing onto the human face in actual applications. This phenomenon not only causes discomfort to patients, such as a wet and cold feeling, and may even cause facial skin problems, but in severe cases, the condensation and overflow of a large number of droplets may hinder gas circulation, affecting the efficiency and safety of gas delivery. In addition, excessive condensation in the mask may also become a culture medium for bacterial growth, increasing the risk of infection.

[0004] For example, an airway humidification device with patent application number CN202320600199.6 discloses "comprising a bottom plate, a liquid storage tank is fixedly mounted on the upper surface of the bottom plate, a base is fixedly mounted on the lower surface of the liquid storage tank, an atomizer is fixedly mounted on the surface of the bottom plate, a mixing tank is fixedly mounted on the end of the atomizer away from the liquid storage tank, and an oxygen supply device is fixedly mounted on the surface of the bottom plate. In the utility model, by arranging the atomizer, the oxygen supply device and the mixing tank and other structures, the humidifying liquid in the liquid storage tank is transported to the atomizer through the pipe for atomization treatment, and the atomization is completed. The moisture will be transported to the mixing tank under the action of the air pump. At the same time, the oxygen supply device is also transporting oxygen to the mixing tank. A stirring paddle is designed inside the mixing tank. The stirring paddle will rotate rapidly under the drive of the motor. During the rotation of the stirring paddle, the moisture and oxygen will be fully mixed. This design can ensure that the patient can be supplied with moisture and oxygen at the same time. "Although the above structure can deliver moisture to the patient; however, since the gas contains a large amount of water vapor, it will cause droplets to condense in the mask. Long-term use will cause the condensed droplets to enter the human face, causing discomfort to the human body.

[0005] In order to solve the above problems, we provide an airway humidification device that can prevent the droplets of condensed humidified gas in the mask from overflowing onto the human face. Utility Model Content

[0006] The utility model aims to overcome the deficiencies in the prior art and provide an airway humidification device.

[0007] The purpose of the utility model is achieved as follows: an airway humidification device comprises an atomizer, the atomizer is connected to a medicine storage box, the atomizer is connected to an air inlet pipe, and the rear end of the air inlet pipe is connected to a mask; a circle of water retaining strips is arranged on the inner side of the mask, a liquid discharge port is arranged at the bottom of the mask, and water storage cotton is arranged in the liquid discharge port.

[0008] Furthermore, a retractable flexible tube is provided between the air inlet pipe and the mask.

[0009] Furthermore, a breathing port is provided at the front end of the mask.

[0010] Furthermore, an arc-shaped groove is provided on the inner side of the water retaining strip.

[0011] Furthermore, a drainage groove is arranged around the drainage port at the bottom of the mask, and water storage cotton is arranged in the drainage groove.

[0012] When the utility model is used, liquid is supplied to the atomizer through the medicine storage box, the atomizer supplies gas containing a large amount of moisture to the air inlet pipe, the gas is supplied to the mask through the retractable flexible tube, and the person inhales the gas containing moisture when breathing and discharges it through the breathing port; when the gas containing a large amount of moisture enters the mask, long-term use will cause a large amount of droplets to form on the inner wall of the mask; ordinary masks will cause droplets to flow to the face of the person, causing discomfort to the person. In order to prevent a large amount of condensed droplets from entering the face of the person, a circle of water retaining strips is provided, so that the condensed droplets cannot flow along the mask to the face.

[0013] The water retaining strip blocks the blocked droplets to the inner wall of the mask, and the droplets are then absorbed by the drainage groove, the drainage port and the liquid storage cotton in the liquid storage box to prevent the droplets from splashing due to the shaking of the mask.

[0014] An arc-shaped groove is provided in the water retaining strip, and the arc-shaped groove can prevent the liquid droplets not absorbed by the liquid storage cotton from escaping from the water retaining strip and splashing onto the human face when the mask shakes.

[0015] Beneficial effects: The present application can provide humidified gas to the patient, and at the same time, a retractable flexible tube is provided to prevent the mask from pulling the patient's face when the patient moves suddenly. A water retaining strip is provided to prevent condensed droplets from covering the human face, and a liquid storage cotton is provided to prevent droplets from overflowing when the mask shakes.
