Embodiment 1

[0042] figure 1 It is a structural diagram of Embodiment 1 of the oxygen surface humidification device of the present invention. see figure 1, the oxygen surface humidification device of the present invention includes a main casing 1 and a humidification unit 2 , and the humidification unit 2 is installed in the main casing 1 . The main housing 1 is made of medical-grade plastic material and is in the shape of a bottle as a whole. The main housing 1 includes a bottle cap 13 and a bottle body 14. The bottle cap 13 and the bottle body 14 are connected by threads. In order to ensure that the bottle cap 13 and the bottle The tightness between the body 14 is installed on the sealing ring 103 at the junction of the bottle cap 13 and the bottle body 14 . The main housing 1 is provided with at least one inlet pipe 11 for dry oxygen to enter the main housing 1 and at least one outlet pipe 12 for humidified oxygen to flow out. The main housing 1 is filled with humidification liquid. ...

Embodiment 2

[0047] figure 2 It is a structural diagram of Embodiment 2 of the oxygen surface humidification device of the present invention. see figure 2 , in the present embodiment, the oxygen guide body 3 is a trumpet-shaped structure, and its small end is connected to a position opposite to the coaxial center of the air intake pipe 11 inside the bottle cap 11, and its horn end opening is close to the humidification umbrella 22. The upper surface, and keep a certain gap with the upper surface of the humidification umbrella 22, so that oxygen can pass through smoothly. The oxygen guide body 3 is arranged in a trumpet-shaped structure, which can guide the flow of dry oxygen to the surface of the humidification umbrella, increase the contact area between oxygen and the humidification umbrella 22, and further enhance the humidification effect.

[0048] In addition, in this embodiment, the humidifying umbrella 22 is installed on the bottle body 14 , and at the same time, an annular step ...

Embodiment 3

[0050] image 3 It is a structural diagram of Embodiment 3 of the oxygen surface humidification device of the present invention. Figure 4 for image 3 The bottom view of the guide body 3 in the shown oxygen surface humidification device; Figure 5 for image 3 Top view of the humidification unit 2 in the shown oxygen surface humidification device. see Figure 3 to Figure 5 The difference between the present embodiment and the second embodiment is that the opening of the oxygen guiding body 3 abuts against the upper surface of the humidification umbrella 22 . A plurality of first guide grooves 131 extending in the radial direction of the humidification umbrella 22 are provided on the lower surface of the open end of the oxygen guide body 3 in contact with the humidification umbrella 22; or, in the The upper surface of the humidification umbrella 22 in contact with the oxygen guide body 3 is provided with a plurality of first guide grooves 131 extending radially along the ...

Abstract

The invention provides an oxygen surface humidifying device which comprises a main shell and a humidifying unit; at least one air inlet pipe allowing dry oxygen to enter the main shell and at least one air outlet pipe allowing humidified oxygen to flow out are arranged on the main shell, and humidifying liquid is contained in the main shell. The humidifying unit is mounted in the main shell and comprises a humidifying core and a humidifying umbrella, one end of the humidifying core extends in the direction of the air inlet pipe and is connected with or integrally formed with the humidifying umbrella, and the other end of the humidifying core extends into the humidifying liquid; dry oxygen enters the main shell through the air inlet pipe, flows through the surface of the humidifying umbrella to be humidified and then flows out through the air outlet pipe. The oxygen surface humidifying device is simple in structure and stable in humidifying effect.

Description

technical field [0001] The invention relates to an oxygen surface humidifying device, which is mainly used for humidifying dry oxygen in a hospital and belongs to the technical field of medical equipment. Background technique [0002] Oxygen inhalation is the most common clinical treatment method, and oxygen needs to be humidified before use. In the traditional water humidification method, bubbles rise from the bottom of the humidification bottle during the humidification process, accompanied by obvious noise and aerosol generation. The surface humidification method in the prior art is to use dry oxygen to flow through the surface of the wetted body to take away the saturated water vapor on the surface to achieve the purpose of oxygen humidification. However, the structural design of the existing oxygen surface humidification device is relatively complicated, requiring multiple humidification components to be assembled, which not only makes the production cost of the device ...
