[0029] Combine the following Figures 1 to 3 As shown, the embodiment of the utility model provides a medical oxygen supply device, including an oxygen storage device 1, the gas outlet of the oxygen storage device 1 is connected to a pressure reducing device 4 through a first gas supply pipeline 2, and the gas outlet of the pressure reducing device 4 is connected to the oxygen supply outlets of each bedside of the hospital through a second gas supply pipeline 6;

[0030] An oxygen inlet chamber 10, an oxygen buffer chamber 13 and a gas mixing chamber 16 are provided inside the decompression device 4. The oxygen inlet chamber 10, the oxygen buffer chamber 13 and the gas mixing chamber 16 are connected in sequence, and an adjusting screw 7 for adjusting the oxygen outlet volume is provided on the upper side of the inner part of the decompression device 4. A sealable slide plate 11 is provided inside the oxygen inlet chamber 10, a plug 19 is provided on the upper part of the inner cavity of the oxygen buffer chamber 13, and a first mixing plate 20 and a second mixing plate 22 are provided inside the gas mixing chamber 16.

[0031] Specifically: the oxygen storage device 1 adopts the existing gas storage device on the market. When other gases need to be added, the other gases and oxygen are mixed for the first time inside the oxygen buffer chamber 13, and then pass through the circular holes 21 on the first mixing plate 20 and the second mixing plate 22, so that the other gases and oxygen will be collided and divided, so that the other gases and oxygen can be mixed more fully, and the gas inhaled by the patient will be more comfortable.

[0032] like Figure 2As shown: the upper side of the shell of the pressure reducing device 4 is movably connected to the adjusting sleeve 8, and the middle part of the upper end of the inner cavity of the adjusting sleeve 8 is fixedly connected with the adjusting screw 7, the lower end of the adjusting screw 7 is connected to the adjusting plate 9 through a bearing, and the adjusting screw 7 is inserted into the middle part of the upper end of the shell of the pressure reducing device 4 through a thread.

[0033] Specifically, the adjusting screw 7 can drive the adjusting plate 9 to move up and down as the adjusting sleeve 8 rotates forward and backward.

[0034] like Figure 1 As shown, the adjustment plate 9 is movably plugged into the upper side of the inner cavity of the shell of the pressure reducing device 4 , and a first sealing ring 17 is provided on the outer side of the adjustment plate 9 .

[0035] Specifically, the first sealing ring 17 can seal the upper portion of the housing of the decompression device 4 to prevent the slide plate 11 from being damaged and leaking.

[0036] like Figure 2 As shown: a second sealing ring is provided on the outer side of the slide plate 11 , the slide plate 11 is limitedly slidably arranged inside the oxygen inlet chamber 10 , and a decompression spring 12 is provided in the middle between the slide plate 11 and the adjustment plate 9 .

[0037] Specifically, the pressure reducing spring 12 can buffer the pressure force of oxygen.

[0038] like Figure 2 As shown: the oxygen inlet chamber 10 and the oxygen buffer chamber 13 are connected via a connecting hole 14, a push rod 15 is movably inserted inside the connecting hole 14, the upper end of the push rod 15 is fixedly connected to the lower end of the slide plate 11, and the lower end of the push rod 15 is fixedly connected to a plug 19.

[0039] Specifically, the push rod 15 is connected to the plug 19 , so that the plug 19 can be displaced along with the up and down displacement of the slide plate 11 .

[0040] like Figure 2 and Figure 3 As shown: a compression spring 18 is provided between the lower end of the plug 19 and the lower side wall of the oxygen buffer chamber 13 , and a sealing layer 26 is fixedly embedded on the upper outer portion of the plug 19 .

[0041] Specifically, the compression spring 18 is always in a compressed state, and the sealing layer 26 can increase the sealing degree of the plug 19 .

[0042] like Figure 2 and Figure 3 As shown: a gas mixing chamber 16 is provided on the right side of the oxygen buffer chamber 13, a first mixing plate 20 is fixedly provided on the left end of the gas mixing chamber 16, and a second mixing plate 22 is movably provided on the right end of the first mixing plate 20, and a plurality of circular holes 21 are evenly penetrated on the first mixing plate 20 and the second mixing plate 22.

[0043] Specifically, the circular holes 21 on the first mixing plate 20 and the second mixing plate 22 are always in an overlapping state. When other gases need to be added, the mixed gas passes through the circular holes 21 on the first mixing plate 20 and the second mixing plate 22, so that the mixed gas will be impacted and divided, so that other gases and oxygen can be mixed more fully.

[0044] like Figure 2 and Figure 3 As shown: a rectangular opening 23 for limiting the insertion of the second mixing plate 22 is opened on the left side of the upper end of the gas mixing chamber 16, a displacement opening 24 is provided on the upper left end of the rectangular opening 23, a connecting rod 25 is fixedly connected to the upper left end of the second mixing plate 22, the connecting rod 25 is movably inserted inside the displacement opening 24, and the left end of the connecting rod 25 is fixedly connected to the outside of the plug 19.

[0045] Specifically, the connecting rod 25 moves up and down as the plug 19 moves up and down, thereby driving the second mixing plate 22 to move up and down.

[0046] like Figure 1 As shown: the left end of the oxygen buffer chamber 13 is connected to the air intake pipe 5, the oxygen air intake chamber 10 is connected to the first air supply pipe 2, the gas mixing chamber 16 is connected to the second air supply pipe 6, the first air supply pipe 2 is provided with a pressure gauge 3, and the air intake pipe 5 is provided with a switch valve.

[0047] Specifically, the pressure gauge 3 adopts the existing pressure gauge on the market, and the pressure gauge 3 can detect the pressure of oxygen inside the first gas supply pipeline 2. The second gas supply pipeline 6 also needs to be equipped with a pressure gauge.

[0048] Working principle: When the valve at the outlet of the oxygen storage device 1 is opened, oxygen will be supplied to the pressure reducing device 4 through the first gas supply pipeline 2. After the oxygen is decompressed by the pressure reducing device 4, it will be supplied to the patient at the bedside of the hospital through the second gas supply pipeline 6;

[0049] If it is not necessary to add other gases into the oxygen, the switch valve on the air intake pipe 5 needs to be closed. If it is necessary to add other gases into the oxygen, the air intake pipe 5 is connected through a pipe, and the other end of the pipe is connected to the gas supply device to be added, and then the switch valve on the air intake pipe 5 is opened to add the gas;

[0050] When oxygen enters the decompression device 4 to reduce pressure, oxygen will exert an upward force on the slide plate 11 to overcome the pressure of the decompression spring 12, and as the slide plate 11 moves upward, the plug 19 will also move upward under the upward force of the compression spring 18. When the plug 19 moves upward to the upper part of the oxygen buffer chamber 13, the amount of oxygen entering the oxygen buffer chamber 13 will be changed, so that the pressure of oxygen after entering the oxygen buffer chamber 13 is greatly reduced. At the same time, by manually twisting the adjustment sleeve 8, the position of the adjustment screw 7 can be adjusted, so that the adjustment plate 9 moves up and down, thereby adjusting the maximum height of the top rod 15, and also adjusting the maximum height of the plug 19. The position of the limit plug 19 can be adjusted to adjust the flow rate of oxygen after decompression;

[0051] Moreover, the circular holes 21 on the first mixing plate 20 and the second mixing plate 22 are always in an overlapping state, that is, when the plug 19 moves upward, the amount of oxygen entering the oxygen buffer chamber 13 decreases, the plug 19 will drive the second mixing plate 22 to move upward, and the overlapping area of ​​the circular holes 21 will also become smaller. On the contrary, when the plug 19 moves downward, the amount of oxygen entering the oxygen buffer chamber 13 increases, the plug 19 will drive the second mixing plate 22 to move downward, and the overlapping area of ​​the circular holes 21 will also become larger. Therefore, the up and down displacement of the second mixing plate 22 will not affect the decompression effect of oxygen.

[0052] And when other gases need to be added, after the other gases and oxygen are mixed for the first time inside the oxygen buffer chamber 13, they will pass through the circular holes 21 on the first mixing plate 20 and the second mixing plate 22, so that the other gases and oxygen will be collided and divided, so that the other gases and oxygen can be mixed more fully, and the gas inhaled by the patient will be more comfortable.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
