Specific embodiments

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. The components of the embodiments of the present utility model described and illustrated herein are generally arranged and designed in a variety of different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but is merely representative of the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0022] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0023] The following is further described in conjunction with specific embodiments. Refer to Figures 1 - 5As shown in the figure, this embodiment is a medical oxygen supply controller, which includes a ventilation seat 2. A flow meter 1 and a humidifying bottle 3 are respectively arranged at both ends of the ventilation seat 2. A flow regulating valve 4 is arranged on the ventilation seat 2. It also includes a connecting seat 5 arranged between the ventilation seat 2 and the humidifying bottle 3; an oxygen supply pipe 9, which is communicated with the ventilation seat 2; a switching valve 6, which passes through the middle of the connecting seat 5. Oxygen inhalation ports 61 and atomizing ports 62 are respectively arranged at both ends of the switching valve 6. A through hole 63 is arranged in the middle of the switching valve 6, and the switching valve 6 is slidably connected with the connecting seat 5; when the switching valve 6 transversely moves towards the oxygen inhalation port 61 side, the oxygen supply pipe 9 is switched to be communicated with the atomizing port 62; when the switching valve 6 transversely moves towards the atomizing port 62 side, the oxygen supply pipe 9 is switched to be sequentially communicated with the through hole 63, the humidifying bottle 3 and the oxygen inhalation port 61; specifically, this oxygen supply controller is usually installed on the wall. The oxygen input through the oxygen supply pipe 9 can be observed through the flow meter 1 to know the amount of oxygen intake, and the amount of oxygen intake is controlled by the flow regulating valve 4. When oxygen inhalation is needed, the humidifying bottle 3 is installed below the connecting seat 5, and the switching valve 6 is pushed axially for a certain distance, so that oxygen enters the connecting seat 5 through the ventilation seat 2, and the oxygen enters the humidifying bottle 3 through the through hole 63 of the switching valve 6, and then is discharged from the side hole at the top of the humidifying bottle 3 and enters the oxygen inhalation port 61 of the switching valve 6 for output. The oxygen inhalation port 61 is connected to a nasal oxygen tube or an oxygen mask. After oxygen inhalation is completed, the flow regulating valve 4 is closed and the humidifying cup is removed; when atomization is needed, the switching valve 6 is pushed in the reverse direction, so that the through hole 63 is misaligned with the hole of the connecting seat 5, and the hole of the connecting seat 5 is aligned and communicated with the atomizing port 62, and oxygen then enters the atomizing port 62 for output. The atomizing port 62 is connected to an atomizer, and the flow regulating valve 4 is closed after the oxygen atomization process is completed. Thus, this controller integrates two functions of oxygen inhalation and atomization, and it is very convenient to switch and use.

[0024] Referring to Figures 1 - 3 As shown in the figure, this embodiment further includes a quick-connect component 8 connected to the ventilation seat 2. The quick-connect component 8 includes a valve body 81, a valve core 82, a first spring 83, a second spring 84 and an outer sleeve 85. The valve core 82 is arranged inside the valve body 81, and the first spring 83 is sleeved on the valve core 82; the outer sleeve 85 is slidably sleeved outside the valve body 81, and both ends of the second spring 84 are respectively abutted between the outer sleeve 85 and the valve body 81. A plurality of steel balls 87 are embedded and installed on the inner wall of the valve body 81. By sliding the outer sleeve 85 to squeeze the second spring 84, the steel balls 87 radially retract into the inner wall of the valve body 81; specifically, in order to further increase the integrated functions of the controller, the quick-connect component 8 is used to connect to a ventilator for use. A special insert of the ventilator trachea is inserted into one end of the valve body 81, the valve core 82 is pushed to open by squeezing the first spring 83, and the insert is fixed in the valve body 81 by the steel balls 87. After use, the outer sleeve 85 is pressed to squeeze the second spring 84, so that the steel balls 87 move radially outward along the valve body 81 and retract, and then the insert is automatically released after losing the restraint of the steel balls 87. At the same time, the valve core 82 is sealed under the action of the gas force and elastic force of oxygen.

[0025] Therefore, the controller integrates the functions of oxygen inhalation, atomization, and connection to a ventilator, improving the usage efficiency and facilitating management.

[0026] Refer to Figure 3 As shown, in order to improve the sealing effect between the valve core 82 and the valve body 81, a first sealing ring 86 is sleeved on the outer surface of the valve core 82, and the first sealing ring 86 is squeezed between the valve body 81 and the valve core 82; in addition, a retaining ring is provided between the valve body 81 and the outer sleeve 85 to prevent the second spring 84 from pushing the outer sleeve 85 to separate from the valve body 81.

[0027] This embodiment further includes a connecting pipe 10 connected to the ventilation seat 2, and the connecting pipe 10 is communicated with the flow meter 1. One end of the connecting pipe 10 is provided with a base assembly 7, and the connecting pipe 10 is detachably connected to the base assembly 7. The middle part of the connecting pipe 10 is provided with a screw cap 101 for fitting the installation surface; specifically, during installation, first fix the base assembly 7, and at the same time connect the pipeline to the oxygen source pipeline, then install the remaining part of the connecting pipe 10 on the base assembly 7, and tighten the screw cap 101 to be tightly fixed against the wall panel. When disassembly and maintenance are required, loosen the screw cap 101, and at the same time rotate the connecting pipe 10 to remove the upper part for maintenance.

[0028] Refer to Figure 5 As shown, sealing gaskets 631 in contact with the inner wall of the connecting seat 5 are provided at both openings on both sides of the through hole 63; the switching valve 6 is slidably connected to the connecting seat 5, and a limit screw 11 for inserting into the switching valve 6 is screwed into the side surface of the connecting seat 5; specifically, the limit screw 11 is installed in the waist-shaped groove of the switching valve 6, and pushing left and right can limit the moving distance of the switching valve 6. When the switching valve 6 is pushed to the extreme position towards the atomizing port 62 side, the oxygen inhalation port 61 is communicated with the through hole 63. When the switching valve 6 is pushed to the extreme position towards the oxygen inhalation port 61 side, the atomizing port 62 is communicated with the through hole 63. The sealing gasket 631 at the through port of the switching valve 6 can prevent oxygen from leaking through the gap between the switching valve 6 and the connecting seat 5.
