Embodiment Construction
[0081] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the disclosure as recited in the claims.
[0082] The invention provides an oxygen humidification device. Dry oxygen is humidified by the oxygen humidification device to form moist oxygen. The first embodiment of the oxygen humidification device provided by the present invention is introduced below.
[0083] Such as figure 1 with figure 2 As shown, in the first embodiment of the oxygen humidification device provided by the present invention...

The invention provides an oxygen wetting device. The oxygen wetting device comprises a housing, a humidifying core, a gas guiding flow channel and a connecting seat, wherein the humidifying core extends into wetting liquid in an accommodating cavity; the connecting seat is provided with a seat chamber; the seat chamber is provided with a chamber wall which extends in the extending direction of thehumidifying core; the top end of the humidifying core is located in the seat chamber; the outer surface of the top end of the humidifying core is propped against the chamber wall in the radial direction of the humidifying core; the gas guiding flow channel comprises a gas guiding groove or a gas guiding hole formed in the chamber wall; one end of the gas guiding flow channel communicates with a gas inlet pipe, and the other end of the gas guiding flow channel communicates with the accommodating cavity; and dry oxygen enters the accommodating cavity along the gas guiding flow channel and is separated from the gas guiding flow channel outside the wetting liquid. Through the adoption of the oxygen wetting device disclosed by the invention, surface wetting is performed on the dry oxygen, so that the dry oxygen can smoothly enter the gas guiding flow channel to enter the accommodating cavity, the air resistance in the oxygen flowing process is reduced, and the situation that the flowing ofthe dry oxygen is not smooth is avoided; and besides, the situation that the dry oxygen enters the inner part of the humidifying core from the top end of the humidifying core can also be avoided, andaerosol is not produced in the wetting process.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to an oxygen humidification device. Background technique [0002] Oxygen inhalation is a common clinical treatment method. Oxygen needs to be humidified before use. There are two main ways to humidify oxygen at present, namely surface humidification and water humidification. Traditional water-entry humidification refers to passing dry gas into the interior of the humidification liquid, and the gas continuously impacts in liquid water and emerges from the water surface, and then mixes with many small droplets to increase the total water content in the gas. The method of water humidification is noisy, and the small droplets can easily carry the aerosol in the water into the airflow, which is harmful to human health, and has been gradually eliminated. Surface wetting refers to the flow of dry gas over the surface of a wetted material and carry away the water vapor. The me...
