[0002] Oxygen inhalers are the core equipment for oxygen therapy measurement and control in hospitals and homes. In hospitals, oxygen is delivered through oxygen supplies or gas cylinders, while at home, oxygen is delivered entirely through oxygen cylinders. Oxygen inhalers are connected to the end of the delivery pipeline or the outlet end of the gas cylinder. Oxygen is delivered to patients who need oxygen therapy through the inhaler and an additional humidification device.

[0003] In the prior art, when a hospital uses an oxygen inhaler on a patient, it is necessary to first connect the oxygen flow meter to the oxygen inhalation device, and then connect the assembled oxygen flow meter to the oxygen supply port. When the patient needs humidified oxygen inhalation, a humidification bottle needs to be installed at the bottom of the oxygen flow meter. The overall operation is too cumbersome, and the oxygen inhalation device is usually connected to the oxygen outlet of the oxygen inhaler using a hose. In this case, if the patient accidentally touches it, the hose may be knocked off the oxygen outlet, causing the patient to be unable to inhale oxygen, affecting the patient's health. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide an intelligent monitoring oxygen inhaler controlled by a touch screen to solve the technical problem that the patient needs to assemble the oxygen inhalation device with the oxygen flow meter and the humidification device before using it, which is too cumbersome to operate, and the oxygen inhalation device is connected to the oxygen flow meter using a hose, which is easy to be accidentally touched by the patient, causing the hose to fall off, affecting the patient's oxygen inhalation.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent monitoring oxygen inhaler controlled by a touch screen, comprising a fixed shell, a connecting mechanism is provided at the bottom of the fixed shell, a humidifying mechanism is provided at the bottom of the connecting mechanism, a self-locking mechanism is provided on one side of the connecting mechanism and a self-locking mechanism is provided on one side of the humidifying mechanism, wherein one group of the self-locking mechanisms is movably connected with the inside of the connecting mechanism by a clamping mechanism, the connecting mechanism comprises a connecting piece and a sealing ring, the connecting piece is located at the bottom of the fixed shell and is fixedly connected thereto, the sealing ring is fixed inside the connecting piece, the self-locking mechanism comprises a self-locking shell, a movable button and a one-way fastening wheel, the self-locking shell is fixed to one side of the connecting mechanism, the inside of the self-locking shell is rotatably connected with two groups of movable buttons, one end of the movable button is rotatably connected to the one-way fastening wheel, the clamping mechanism comprises a slider, a driving rod, a movable rod and a movable cavity, the slider is located inside the self-locking mechanism and is slidably connected thereto, a driving rod is provided at the end of the slider, the outer walls on both sides of the driving rod are movably connected with movable rods, an movable cavity is provided outside the movable rod, and the movable cavity is opened inside the connecting piece.

[0006] By adopting the above technical scheme, the present invention is that when the oxygen inhaler is used, the gas flow meter body is always installed on the oxygen supply belt. Therefore, when direct oxygen inhalation is required, the hose of the oxygen inhalation device can be inserted into the self-locking mechanism, the hose will be locked and difficult to withdraw, and the situation that the hose is accidentally touched by others and causes it to fall off is prevented. When the patient needs atomization oxygen inhalation, the humidification mechanism can be directly inserted into the device, and the plugging head can fix the humidification mechanism while blocking a group of oxygen outlets, and the self-locking mechanism is also provided on the outside of the humidification mechanism. At the same time, the display screen can display and adjust the oxygen flow concentration, and has a self-locking function. Only the authority of medical staff can unlock the device to adjust the oxygen flow and concentration. When the patient installs the oxygen inhalation device but does not inhale oxygen, the gas flow sensor device inside the device will detect the oxygen flow abnormality, so that an alarm appears on the display screen, which solves the technical problems that the patient needs to assemble the oxygen inhaler by medical staff before inhaling oxygen, the operation is too cumbersome, and the oxygen inhalation device uses a hose to connect with the oxygen flow meter, which is easy to be accidentally touched and cause the hose to fall off, affecting the patient's oxygen inhalation.

[0007] Furthermore, a display screen is provided on one side of the fixed shell, a battery is provided inside the fixed shell, a signal processing and control circuit is provided on one side of the battery, and the signal processing and control circuit is electrically connected to the display screen, a gas flow meter body is provided inside the fixed shell, a gas flow sensor device is provided on the top of the gas flow meter body, and the gas flow sensor device is electrically connected to the signal processing and control circuit, a gas flow electromagnetic regulating valve is provided on one side of the gas flow meter body, and the gas flow electromagnetic regulating valve is electrically connected to the signal processing and control circuit, and a fixed connecting mechanism is provided on one side of the fixed shell, and the gas flow meter body and the fixed connecting mechanism are connected.

[0008] By adopting the above technical solution, medical staff can use the display screen to control the opening and closing state of the gas flow electromagnetic regulating valve by the signal processing and control circuit, thereby controlling the flow and concentration of oxygen. After passing through the gas flow sensor device, the flow and concentration of oxygen will be displayed in digital form on the display screen, which is convenient for medical staff to adjust the flow and concentration of oxygen. After the patient starts to inhale oxygen, the display screen will automatically lock to prevent others from accidentally touching the display screen during the patient's oxygen inhalation, thereby affecting the patient's oxygen inhalation.

[0009] Furthermore, the self-locking mechanism also includes a first rotating shaft, a spring and a vent head, the first rotating shaft is located inside the self-locking shell and is movably connected thereto, the spring is located between the movable button and the self-locking shell, and the movable button is elastically connected to the self-locking shell through the spring, the vent head is located inside the self-locking shell, one group of the self-locking mechanisms is provided with a sealing head at one end, the sealing head and the vent head are in interference fit, a one-way bearing is provided inside the one-way fastening wheel, and anti-slip texture is provided on the surface of the one-way fastening wheel.

[0010] By adopting the above technical solution, after the hose of the oxygen inhalation device is inserted into the self-locking mechanism on one side of the connecting mechanism, the hose will first lift up the two sets of one-way fastening wheels, and a one-way bearing is installed inside the one-way fastening wheel. Therefore, after the hose passes through the one-way fastening wheel, it will be locked by the one-way fastening wheel, so that the hose can only enter the self-locking mechanism and cannot exit. After the medical staff takes out the hose by pressing the movable button, after releasing the movable button, under the elastic action of the spring, the movable button and the one-way fastening wheel will return to the initial position, so that when the patient continues to inhale oxygen, the hose of the oxygen inhalation device can be locked.

[0011] Furthermore, the locking mechanism also includes a blocking block and a second rotating shaft, the blocking block is located at one end of the slider and is fixedly connected thereto, the second rotating shaft is located inside the movable rod, and the second rotating shaft is rotationally connected to the connecting mechanism, a sliding groove is provided inside the self-locking shell, and the cross-sectional size of the sliding groove inside the self-locking shell matches the cross-sectional size of the blocking block.

[0012] By adopting the above technical solution, after the hose enters the self-locking mechanism for a certain distance, it will push the slider to slide inside the self-locking shell. At the same time, the slider will push the driving rod to move and cause the sealing ring to deform. The two ends of the driving rod are located inside the two groups of movable rods, and the movable rods rotate inside the movable cavity through the second rotating shaft. Therefore, when one group of driving rods moves toward the center position of the sealing ring, it will force the movable rod to drive the other group of driving rods to move.

[0013] Furthermore, the humidification mechanism includes a humidification bottle, a connecting head and a fixed head. The humidification bottle is located at the bottom of the connecting mechanism.

After the humidifying mechanism is inserted into the connecting mechanism, the sealing head is taken out and inserted into the self-locking mechanism next to the connecting mechanism, which will also push the slider to move, so that the driving rod can drive the sealing ring to deform. At this time, the sealing ring is wrapped with the fixed head to form a clamping effect on the fixed head, thereby ensuring that the humidifying mechanism will not fall off easily after being connected to the interior of the connecting mechanism. Then, after passing through the interior of the device, the oxygen will enter the humidifying mechanism through the connecting mechanism. The humidified oxygen will flow out from the hose next to the fixed head and will be sucked away by the patient.

[0015] In summary, the present invention mainly has the following beneficial effects:

[0016] 1. When the oxygen inhaler is used, the gas flow meter body is always installed on the oxygen supply belt, and the display screen installed outside the oxygen inhaler can display and adjust the oxygen flow, oxygen concentration, oxygen inhalation time and total oxygen amount, and has self-locking and alarm functions.

[0017] 2. When direct oxygen inhalation is required, the hose of the oxygen inhalation device can be inserted into the self-locking mechanism, and the hose will be locked and difficult to withdraw, thereby preventing the hose from falling off due to accidental touching by the patient. When the patient needs atomized oxygen inhalation, the humidification mechanism can be directly inserted into the device, and the blocking head can fix the humidification mechanism while blocking a group of oxygen outlets. A self-locking mechanism is also provided on the outside of the humidification mechanism, which solves the technical problem that the patient needs medical staff to assemble the oxygen inhaler before using it, which is too cumbersome to operate, and the oxygen inhalation device uses a hose connected to the oxygen flowmeter, which is easy to be accidentally touched and cause the hose to fall off, affecting the patient's oxygen inhalation.

DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The following describes an embodiment of the present invention based on its overall structure.

[0034] An intelligent monitoring oxygen inhaler controlled by a touch screen, such as Figure 1-13As shown, it includes a fixed shell 1, a connecting mechanism 2 is provided at the bottom of the fixed shell 1, a humidifying mechanism 5 is provided at the bottom of the connecting mechanism 2, a self-locking mechanism 3 is provided on one side of the connecting mechanism 2 and a self-locking mechanism 3 is provided on one side of the humidifying mechanism 5, wherein a group of the self-locking mechanisms 3 is movably connected with the inside of the connecting mechanism 2 by a locking mechanism 4, wherein the connecting mechanism 2 includes a connecting member 201 and a sealing ring 202, the connecting member 201 is located at the bottom of the fixed shell 1 and is fixedly connected thereto, and the sealing ring 202 is fixed inside the connecting member 201;

[0035] Furthermore, the self-locking mechanism 3 includes a self-locking housing 301, a movable button 303 and a one-way fastening wheel 305. The self-locking housing 301 is fixed to one side of the connecting mechanism 2, the interior of the self-locking housing 301 is rotatably connected to the two sets of movable buttons 303, and one end of the movable button 303 is rotatably connected to the one-way fastening wheel 305;

[0036] When the patient needs to inhale oxygen, the hose is inserted into the self-locking mechanism 3. After the hose is inserted into the self-locking mechanism 3, the upper and lower sets of one-way fastening wheels 305 will be lifted up first, and one-way bearings are installed inside the one-way fastening wheels 305. Therefore, the hose will be locked by the one-way fastening wheels 305, so that the hose can only enter the self-locking mechanism 3 and is difficult to exit from the self-locking mechanism 3, ensuring that the hose will not fall off when the patient accidentally touches the hose.

[0037] When the patient has finished inhaling oxygen, the medical staff can manually press the movable buttons 303 at the upper and lower ends of the self-locking mechanism 3, and one end of the movable button 303 will be lifted up under the action of the first rotating shaft 302, so that the one-way fastening wheel 305 is not in contact with the hose, thereby releasing the restriction of the self-locking mechanism 3 on the hose, making it convenient for the user to pull the hose out of the self-locking mechanism 3;

[0038] Further, the locking mechanism 4 includes a slider 402, a driving rod 403, a movable rod 404 and a movable cavity 406. The slider 402 is located inside the self-locking mechanism 3 and is slidably connected thereto. The driving rod 403 is provided at the end of the slider 402. The outer walls on both sides of the driving rod 403 are movably connected with the movable rod 404. The movable cavity 406 is provided outside the movable rod 404, and the movable cavity 406 is opened inside the connecting member 201.

[0039] After the hose enters the self-locking mechanism 3 for a certain distance, it will contact the slider 402 and push the slider 402, and at the same time push the driving rod 403 to move. Since the sealing ring 202 itself is made of rubber material and the driving rod 403 penetrates both sides of the sealing ring 202, the driving rod 403 will force the sealing ring 202 to deform when it moves.

[0040] After the two sets of driving rods 403 move to the center of the sealing ring 202, the inner wall of the sealing ring 202 will fit tightly, thereby preventing the oxygen flowing out of the gas flow meter body 10 from passing through the position of the sealing ring 202. In this way, the oxygen will only pass through the self-locking mechanism 3 and then be inhaled by the patient through the hose;

[0041] When the patient needs atomized oxygen inhalation, the medical staff can insert the plugging head 13 into the self-locking mechanism 3 next to the connecting mechanism 2. The one-way fastening wheel 305 can ensure that the plugging head 13 is difficult to withdraw from the self-locking mechanism 3.

[0042] Afterwards, the sealing head 13 will also push the slider 402 to move, thereby moving the driving rod 403, and further deforming the sealing ring 202. At this time, the sealing ring 202 is wrapped with the fixing head 503, and the driving rod 403 will form a clamping effect on the fixing head 503, thereby ensuring that the humidification mechanism 5 will not fall off easily after being connected to the inside of the connecting mechanism 2, thereby achieving a self-locking effect on the humidification mechanism 5.

[0043] See also Figure 8 and Fig. 9 A display screen 6 is provided on one side of the fixed shell 1, a battery 8 is provided inside the fixed shell 1, a signal processing and control circuit 7 is provided on one side of the battery 8, and the signal processing and control circuit 7 is electrically connected to the display screen 6, a display screen 6 is provided on one side of the fixed shell 1, a battery 8 is provided inside the fixed shell 1, a signal processing and control circuit 7 is provided on one side of the battery 8, and the signal processing and control circuit 7 is electrically connected to the display screen 6, a gas flow electromagnetic regulating valve 11 is provided on one side of the gas flow meter body 10, and the gas flow electromagnetic regulating valve 11 is electrically connected to the signal processing and control circuit 7, a fixed communication mechanism 12 is provided on one side of the fixed shell 1, and the gas flow meter body 10 and the fixed communication mechanism 12 are connected;

[0044] The medical staff can use the display screen 6 to control the signal processing and control circuit 7 to control the opening and closing state of the gas flow electromagnetic regulating valve 11, thereby controlling the flow and concentration of oxygen;

[0045] The flow rate and concentration of oxygen will be displayed in digital form on the display screen 6 after passing through the gas flow sensor device 9, so that the medical staff can adjust the flow rate and concentration of oxygen. After the patient starts to inhale oxygen, the display screen 6 will be automatically locked to prevent others from accidentally touching the display screen 6 during the patient's oxygen inhalation, thereby affecting the patient's oxygen inhalation.

[0046] See also Figure 3 and Figure 4The self-locking mechanism 3 further includes a first rotating shaft 302, a spring 304 and a vent head 306. The first rotating shaft 302 is located inside the self-locking housing 301 and is movably connected thereto. The spring 304 is located between the movable button 303 and the self-locking housing 301, and the movable button 303 is elastically connected to the self-locking housing 301 through the spring 304. The vent head 306 is located inside the self-locking housing 301. A plugging head 13 is provided at one end of one group of the self-locking mechanisms 3. The plugging head 13 and the vent head 306 are interference fit. A one-way bearing is provided inside the one-way fastening wheel 305, and an anti-slip pattern is provided on the surface of the one-way fastening wheel 305.

[0047] After the hose of the oxygen inhalation device is inserted into the self-locking mechanism 3 on one side of the connecting mechanism 2, the hose will first lift up the two sets of one-way fastening wheels 305, and a one-way bearing is installed inside the one-way fastening wheel 305. At the same time, the surface of the one-way fastening wheel 305 is provided with anti-slip textures, so the hose will be locked by the one-way fastening wheel 305, so that the hose can only enter the self-locking mechanism 3 and is difficult to exit;

[0048] After the medical staff removes the hose by pressing the movable button 303 and releases the movable button 303, the movable button 303 and the one-way fastening wheel 305 return to their initial positions under the elastic action of the spring 304, so that the hose of the oxygen inhalation device can be locked when the patient continues to inhale oxygen.

[0049] See also Figure 3 , Figure 5 , Figure 6 and Fig.10 The locking mechanism 4 further includes a block 401 and a second rotating shaft 405. The block 401 is located at one end of the slider 402 and is fixedly connected thereto. The second rotating shaft 405 is located inside the movable rod 404, and the second rotating shaft 405 is rotationally connected to the connecting mechanism 2. A sliding groove is provided inside the self-locking housing 301, and the cross-sectional size of the sliding groove inside the self-locking housing 301 matches the cross-sectional size of the block 401.

[0050] After the hose enters the self-locking mechanism 3 for a certain distance, it will push the slider 402 to slide inside the self-locking shell 301. At the same time, the slider 402 will push the driving rod 403 to move and cause the sealing ring 202 to deform. The two ends of the driving rod 403 are located inside the two groups of movable rods 404, and the movable rods 404 rotate inside the movable cavity 406 through the second rotating shaft 405. Therefore, one group of driving rods 403 moves toward the center of the sealing ring 202, which will force the movable rods 404 to drive the other group of driving rods 403 to move.

[0051] See also Figure 3 and Figure 7The humidification mechanism 5 includes a humidification bottle 501, a connector 502 and a fixed head 503. The humidification bottle 501 is located at the bottom of the connection mechanism 2. The top of the humidification bottle 501 is provided with a connector 502. The top of the connector 502 is provided with a fixed head 503. The fixed head 503 and the sealing ring 202 are interference fit. A self-locking mechanism 3 is provided on one side of the connector 502. The ventilation head 306 is connected to the external nasal tube.

[0052] The humidifying mechanism 5 is inserted into the interior of the device from the bottom of the connecting mechanism 2, and the fixing head 503 of the humidifying mechanism 5 and the sealing ring 202 are interference fit, which can ensure that the humidifying mechanism 5 is initially fixed on the connecting mechanism 2;

[0053] After the humidifying mechanism 5 is inserted into the connecting mechanism 2, the plugging head 13 is taken out and inserted into the self-locking mechanism 3 beside the connecting mechanism 2, which also pushes the slider 402 to move, so that the driving rod 403 can drive the sealing ring 202 to deform, and the sealing ring 202 is wrapped with the fixing head 503 to form a clamping effect on the fixing head 503, thereby ensuring that the humidifying mechanism 5 will not fall off easily after being connected to the inside of the connecting mechanism 2;

[0054] After passing through the inside of the device, the oxygen will enter the humidification mechanism 5 through the connecting mechanism 2. The humidified oxygen will flow out from the hose next to the fixed head 503 and will be inhaled by the patient.

[0055] The working principle of the present invention is as follows: when in use, the user can first take out the whole device, fix the device on the oxygen supply belt of the hospital through the fixed connecting mechanism 12 on one side of the fixed shell 1, and start the device, so that the oxygen supply belt supplies oxygen into the device;

[0056] When the patient needs to inhale oxygen directly, the hose of the oxygen inhalation device is inserted into the self-locking mechanism 3 on one side of the connecting mechanism 2, and the hose will wrap the ventilation head 306. When the hose is inserted into the self-locking mechanism 3, the hose will first lift up the two sets of one-way fastening wheels 305, and the one-way bearing is installed inside the one-way fastening wheel 305. Therefore, after the hose passes through the one-way fastening wheel 305, it will be locked by the one-way fastening wheel 305, so that the hose can only enter the self-locking mechanism 3 and cannot exit;

[0057] After the hose enters the self-locking mechanism 3 for a certain distance, it will contact the slider 402 and push the slider 402 to slide inside the self-locking housing 301. At the same time, the slider 402 will push the driving rod 403 to move. Since the sealing ring 202 itself is made of rubber material and the driving rod 403 passes through both sides of the sealing ring 202, when the driving rod 403 moves inward, it will force the sealing ring 202 to deform.

[0058] The two ends of the driving rod 403 are located inside the two groups of movable rods 404, and the movable rods 404 are movable inside the movable cavity 406 via the second rotating shaft 405. At this time, one group of driving rods 403 moves toward the center of the sealing ring 202, which forces the movable rod 404 to rotate inside the movable cavity 406 with the second rotating shaft 405 as the center, thereby driving the other group of driving rods 403 to move;

[0059] The two sets of driving rods 403 move toward the center of the sealing ring 202 at the same time, so that the sealing ring 202 is deformed. When the two sets of driving rods 403 move to the center of the sealing ring, the inner wall of the sealing ring 202 is tightly fitted, thereby preventing the oxygen from the gas flow meter body 10 from passing through the position of the sealing ring 202. In this way, the oxygen will pass through the ventilation head 306 and then be inhaled by the patient through the hose;

[0060] When the patient needs to remove the oxygen inhalation device from the oxygen flow meter after oxygen inhalation, the user can manually press the movable buttons 303 at the upper and lower ends of the self-locking mechanism, and one end of the movable button 303 will be lifted up with the one-way fastening wheel 305 under the action of the first rotating shaft 302, thereby releasing the restriction of the self-locking mechanism 3 on the hose, making it convenient for the user to pull the hose out of the self-locking mechanism 3;

[0061] When the patient needs to absorb oxygen through atomization, the humidification mechanism 5 can be inserted into the interior of the connection mechanism 2 from the bottom of the connection mechanism 2, and the inner diameter of the sealing ring 202 is slightly smaller than the outer diameter of the fixed head 503, so that the fixed head 503 and the sealing ring 202 are interference-fitted, thereby ensuring that the oxygen from the gas flow meter body 10 enters the interior of the humidification bottle 501 through the fixed head 503;

[0062] After the humidifying mechanism 5 is inserted into the connecting mechanism 2, the user takes out the plugging head 13 and inserts it into the self-locking mechanism 3 next to the connecting mechanism 2. The one-way fastening wheel 305 ensures that the plugging head 13 will not withdraw from the self-locking mechanism 3. After the plugging head 13 enters a certain distance inside the self-locking mechanism 3, it will also push the slider 402 to move, thereby moving the driving rod 403 and deforming the sealing ring 202.

[0063] At this time, the sealing ring 202 wraps the fixing head 503, and the driving rod 403 moves toward the inside of the sealing ring 202, which will form a clamping effect on the fixing head 503, thereby ensuring that the humidifying mechanism 5 will not fall off easily after being connected to the inside of the connecting mechanism 2;

[0064] At this time, the hose of the oxygen inhalation device is also taken out and inserted into the self-locking mechanism 3 connected to one side of the humidification mechanism 5. The hose will be locked by the self-locking mechanism 3 and cannot be withdrawn. After the oxygen enters the humidification bottle 501 through the fixed head 503 and is humidified, it will enter the self-locking mechanism 3 through the connecting head 502 on the top of the humidification bottle 501, and enter the hose from the ventilation head 306 inside the self-locking mechanism 3, and then be inhaled by the patient.

[0065] After the medical staff has adjusted the equipment and installed the oxygen inhalation device for the patient, because the display screen 6 is a liquid crystal touch screen, the medical staff can click the display screen 6 to make the signal processing and control circuit 7 control the opening and closing state of the gas flow electromagnetic regulating valve 11, thereby controlling the flow rate and concentration of oxygen. The flow rate and concentration of oxygen will be displayed in digital form on the display screen 6 after passing through the gas flow sensor device 9, which is convenient for the medical staff to adjust the flow rate and concentration of oxygen.

[0066] After the patient starts to inhale oxygen, the display screen 6 will be automatically locked, and the unlocking requires the permission of medical staff to prevent the patient from accidentally touching the display screen 6 during the oxygen inhalation process, thereby affecting the patient's oxygen inhalation;

[0067] During the patient's oxygen inhalation process, the gas flow sensor device 9 will always monitor the inside of the gas flow meter body 10 to monitor the oxygen flow rate, and when the patient's oxygen inhalation state is abnormal or oxygen leaks, the gas flow sensor device 9 can send an electrical signal to the signal processing and control circuit 7, so that the buzzer inside the device will sound an alarm, so that medical staff can find the abnormality of the patient's oxygen inhalation in time;

[0068] When the patient is breathing oxygen, the display screen 6 will always display the oxygen flow, oxygen concentration, oxygen breathing time and total oxygen volume, so that the medical staff can monitor the patient's oxygen breathing status at all times. After the oxygen breathing is finished, the display screen 6 will also display the patient's total oxygen breathing volume, providing a scientific and objective basis for charging oxygen. After each patient is discharged from the hospital, the medical staff can operate the display screen 6 with their own authority to reset the oxygen breathing volume to zero.

[0069] With the above structure, when the oxygen inhaler is used, the gas flow meter body 10 is always installed on the oxygen supply belt. Therefore, when oxygen inhalation is required directly, the hose of the oxygen inhalation device can be directly inserted into the self-locking mechanism 3. After the hose is inserted into the self-locking mechanism 3, it will be locked and difficult to withdraw, thereby preventing the hose from falling off due to accidental contact by the patient.

[0070] When the patient needs atomized oxygen inhalation, the humidification mechanism 5 can be directly inserted into the device, and the plugging head 13 can fix the humidification mechanism 5, and the self-locking mechanism 3 is also provided on the outside of the humidification mechanism 5, so that the patient can always inhale oxygen;

[0071] The display screen 6 can display and adjust the oxygen flow concentration and has a self-locking function. Only medical staff can unlock the device to adjust the oxygen flow and concentration. When the patient does not inhale oxygen, the gas flow sensor device 9 inside the device will detect abnormal oxygen flow, so that the buzzer inside the device will sound an alarm.

[0072] It solves the technical problems that the oxygen inhaler needs to be assembled by medical staff before the patient can use it, which is too cumbersome to operate, and the oxygen inhalation device uses a hose connected to the oxygen flow meter, which is easy to be accidentally touched and cause the hose to fall off, affecting the patient's oxygen inhalation.
