Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an adjustable intermittent oxygen supply device for respiratory rehabilitation training. Background Art

[0002] Pediatric pneumonia is a common disease in infancy and young children. In the early years, pediatric pneumonia was a common cause of death in infants and young children. With the advancement of modern medicine, pneumonia has become very easy to cure. However, after pneumonia is cured, due to the large-scale fragmentation of alveoli during the onset of the disease, problems such as respiratory function weakness will still occur. A series of postoperative rehabilitation measures are needed to help patients gradually restore their original lung capacity.

[0003] During rehabilitation training, in order to prevent the user from inhaling dry oxygen, which may cause chapped lips and respiratory pain in the user, the oxygen supplied by the oxygen supply device is usually humidified. In the prior art, a Chinese invention patent with announcement number CN109833555B discloses an oxygen humidification bottle. The utility model comprises a bottle body, a bottle cap, and an oxygen inlet pipe and an oxygen discharge pipe inserted in the bottle cap. An oxygen humidification mechanism is arranged at one end of the oxygen inlet pipe located in the inner cavity of the bottle body. The oxygen humidification mechanism comprises a rotating body rotatably arranged on the oxygen inlet pipe, and the driving force for the rotation of the rotating body is provided by the oxygen flowing in the oxygen inlet pipe. A gas collecting groove is arranged at the center position of the top of the rotating body, and the gas collecting groove is communicated with the oxygen inlet pipe and is rotatably connected with the oxygen inlet pipe. A plurality of radially distributed gas distribution channels are arranged at intervals on the rotating body between the outer edge of the rotating body and the gas collecting groove. All the gas distribution channels are arc-shaped and the bending direction of all the gas distribution channels along the circumference of the rotating body is consistent. The device can increase the specific surface area of ​​oxygen bubbles in contact with distilled water and prolong the travel of oxygen bubbles discharged from the distilled water, thereby significantly improving the humidification effect of oxygen.

[0004] The above-mentioned device drives the rotating body to rotate through the upper air channel, and the lower air channel discharges oxygen in a larger gas range, thereby realizing uniform diffusion of oxygen in distilled water. However, since the axis of the air outlet of the air channel in the above-mentioned device is still close to vertical to the axis of the rotating body, it only changes the curvature of the upper and lower air channels, which can change the passage time of oxygen through air channels with different curvatures. However, the power to drive the rotating body to rotate is relatively small, which in turn affects the direction of oxygen travel after leaving the air channel, and is not enough to prolong the travel distance and time of oxygen discharge from distilled water, ultimately affecting the humidification effect of oxygen. Summary of the invention

[0014] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0015] The present invention can change the curvature of the exhaust pipe and the outlet direction of the exhaust pipe by setting a squeezing bag 1, so that the squeezing bag 1 on the upper side is first expanded to a full state, and then the squeezing bag 1 on the lower side is expanded to a full state, and the maximum expansion degrees of the squeezing bags 1 at different upper and lower positions are different, so that the curvatures of the upper and lower air distribution pipes are changed. The curvature of the lower air distribution pipe is smaller, and oxygen can retain more power when passing through the air distribution pipe, so that the oxygen is farther away from the axis of the oxygen supply bottle after entering the distilled water; while the curvature of the upper air distribution pipe is larger, which can provide more power for the rotation of the rotating body, and the power loss of the oxygen in the air distribution pipe is more, so that the oxygen is closer to the axis of the oxygen supply bottle after leaving the air distribution pipe, so that the bubbles formed by the oxygen in the distilled water are more uniform and will not affect each other, so as to avoid the oxygen bubbles from contacting and adhering to each other or merging into large bubbles, thereby reducing the contact area between the oxygen bubbles and the distilled water and affecting the humidification effect of the oxygen;

[0016] Secondly, the present invention arranges the trigger bag and the squeeze bag 2. When the distilled water is heated, the heat can be transferred to the trigger bag. At this time, the paraffin in the medium layer is melted, and the gas in the squeeze bag 1 can enter the squeeze bag 2. When the squeeze bag 2 expands, it can push the middle position of the gas distribution pipe to move upward, thereby realizing the downward displacement of the gas outlet end of the gas distribution pipe, so that when the oxygen enters the distilled water through the gas distribution pipe, it moves toward the bottom of the oxygen supply bottle, thereby accelerating the rate at which the oxygen leaves the distilled water after the distilled water is heated, prolonging the time of oxygen in the distilled water, and maintaining the humidity of the oxygen on the premise of replenishing heat energy to the oxygen molecules, thereby enhancing the comfort of the user during breathing training;

[0017] Thirdly, the present invention can increase the hardness of the medium layer by filling the medium layer with metal powder. When the air distribution pipe receives the resistance of distilled water, the medium layer with hardness can produce a certain resistance to the resistance of distilled water, thereby reducing the possibility of deviation of the outlet end of the air distribution pipe. In addition, the metal powder can also accelerate the transfer of heat, so that the paraffin can respond to the temperature change more quickly, thereby ensuring the humidification and heating effect of oxygen, and further improving the comfort of the user in breathing training.

[0018] Fourthly, the present invention realizes uniform heating of oxygen by changing the filling amount of metal powder in the upper and lower gas distribution pipe groups, and reduces the response time of oxygen heating, thereby further improving the comfort of the user during breathing training.

[0034] Embodiment 1: Figure 1-Figure 6 , Fig. 9As shown, the embodiment of the present application provides an adjustable intermittent oxygen supply device for respiratory rehabilitation, including an oxygen supply bottle 100, an oxygen supply cover 120, an air inlet pipe 130 and an exhaust pipe 140. The oxygen supply bottle 100 is provided with an opening facing upward, distilled water is injected into the oxygen supply bottle 100, the oxygen supply cover 120 is detachably fixed to the top of the oxygen supply bottle 100, the air inlet pipe 130 is mounted on the oxygen supply cover 120, and the air inlet pipe 130 extends downward to a lower position inside the oxygen supply bottle 100, an end of the air inlet pipe 130 away from the oxygen supply bottle 100 is connected to an oxygen source (not shown in the figure), the exhaust pipe 140 is mounted on the oxygen supply cover 120, and an end of the exhaust pipe 140 away from the oxygen supply cover 120 is connected to a breathing mask (not shown in the figure), and The invention comprises a rotating body 150, wherein a support plate 110 is installed at the inner bottom of the oxygen supply bottle 100, wherein the bottom of the rotating body 150 is rotatably connected to the support plate 110, wherein an air collecting groove 151 is provided inside the rotating body 150, wherein the top of the rotating body 150 is rotatably connected to the air inlet pipe 130, and the air collecting groove 151 is communicated with the air inlet pipe 130, wherein a plurality of air pipe groups 200 are installed in the rotating body 150, wherein the plurality of air pipe groups 200 are arranged in sequence from top to bottom along the axis direction of the rotating body 150, wherein each air pipe group 200 comprises a plurality of air distribution components, wherein the plurality of air distribution components are fixedly installed in the rotating body 150 in a circular array, wherein each air distribution component comprises an air distribution pipe 210, a fixing plate 220 and a control plate 230, wherein the control plate 230 and the fixing plate 220 are both The control panel 230 is fixed in the rotating body 150, and the fixing plate 220 is located on the side of the control panel 230 away from the axis of the rotating body 150. A through hole 231 is opened on the control panel 230. One end of the air distribution pipe 210 is fixed on the rotating body 150, and the air distribution pipe 210 is connected to the air collecting groove 151. The other end of the air distribution pipe 210 passes through the through hole 231 and is connected to the fixing plate 220 through the ball head 221. An extrusion bag 300 is installed on the inner wall of one side of the through hole 231 in the control panel 230, and the air distribution pipe 210 is made of elastic material. When the extrusion bag 300 expands, it can squeeze the air distribution pipe 210 and make the air distribution pipe 210 bend and deform. When the extrusion bag 300 expands, it can squeeze the middle position of the air distribution pipe 210, thereby making the air distribution pipe 210 The middle part of the air distribution pipe 210 is bent and deformed. Since one end of the air distribution pipe 210 is fixed on the rotating body 150, the other end of the air distribution pipe 210 is connected to the fixing plate 220 through the ball head 221 (since the length of the air distribution pipe 210 remains unchanged, in order to avoid the air distribution pipe 210 being deformed by the thrust of the squeeze bag 300 and conflicting with the fixing force of the ball head 221 on it, the air distribution pipe 210 is slidably connected to the ball head 221, and the air distribution pipe 210 will not be separated from the ball head 221. This is the prior art and will not be elaborated on). Therefore, when the middle part of the air distribution pipe 210 is bent, the air outlet end of the air distribution pipe 210 can be rotated in the opposite direction of the bending direction in the middle, so that the air distribution pipe 210 forms an arc at one end, and the air outlet direction of the air distribution pipe 210 is changed.When oxygen enters the oxygen supply bottle 100 through the gas distribution pipe 210, it can provide more power for the rotating body 150. The oxygen enters the distilled water to form bubbles, and finally enters the breathing mask through the exhaust pipe 140, waiting for the user to perform breathing training.

[0035] Preferably, it also includes an air supply pipe 170 and a shunt pipe 180, wherein the air supply pipe 170 is fixed at the bottom of the oxygen supply bottle 100, the shunt pipe 180 is fixed inside the rotating body 150, and the air outlet end of the shunt pipe 180 is connected to a plurality of extrusion bags 300, the air inlet end of the shunt pipe 180 is rotatably sealed and connected to the air supply pipe 170, and one end of the air supply pipe 170 away from the shunt pipe 180 is connected to the air pump.

[0036] Preferably, the elastic coefficient of the squeezing bag 300 in the air pipe group 200 located on the upper side is greater than the elastic coefficient of the squeezing bag 300 in the air pipe group 200 located on the lower side; the maximum expansion degree of the squeezing bag 300 in the air pipe group 200 located on the upper side is greater than the maximum expansion degree of the squeezing bag 300 in the air pipe group 200 located on the lower side.

[0037] When the air pump is working, the gas enters each squeezing bag 300 through the gas supply pipe 170 and the shunt pipe 180, thereby driving the multiple squeezing bags 300 to expand, changing the curvature of the gas distribution pipe 210 and the gas outlet direction of the gas distribution pipe 210, and because the elastic coefficient of the squeezing bag 300 in the gas distribution pipe group 200 located on the upper side is greater than the elastic coefficient of the squeezing bag 300 in the gas distribution pipe group 200 located on the lower side; the maximum expansion degree of the squeezing bag 300 in the gas distribution pipe group 200 located on the upper side is greater than the maximum expansion degree of the squeezing bag 300 in the gas distribution pipe group 200 located on the lower side, so the gas input by the air pump can first make the squeezing bag 300 on the upper side expand to a full state, and then make the squeezing bag 300 on the lower side expand to a full state, and through the squeezing bags 300 at different positions on the upper and lower sides. 00 has a different maximum expansion degree, which changes the curvature of the upper and lower air distribution pipes 210. The air distribution pipe 210 on the lower side has a smaller curvature, and oxygen can retain more power when passing through the air distribution pipe 210, so that the oxygen is further away from the axis of the oxygen supply bottle 100 after entering the distilled water; while the air distribution pipe 210 on the upper side has a larger curvature, which can provide more power for the rotation of the rotating body 150, and the oxygen in the air distribution pipe 210 loses more power in the air distribution pipe 210, so that the oxygen is closer to the axis of the oxygen supply bottle 100 after leaving the air distribution pipe 210, so that the bubbles formed by oxygen in the distilled water are more uniform and will not affect each other, avoiding the oxygen bubbles from contacting and sticking to each other or merging into large bubbles, reducing the contact area between the oxygen bubbles and the distilled water, and affecting the humidification effect of the oxygen.

[0038] Preferably, an intermittent control component 190 is also installed in the exhaust pipe 140, and the intermittent control component 190 includes a valve body 191, a button 192, a support rod 193, a valve core baffle 194 and a magnet 195. The valve body 191 is installed in the exhaust pipe 140, and the valve body 191 is connected to the exhaust pipe 140. The button 192 is slidably installed on the valve body 191, and a spring is installed between the button 192 and the valve body 191. The support rod 193 is installed on a side of the button 192 close to the valve body 191, and the support rod 193 extends to the inside of the valve body 191. The valve core baffle 194 is slidably installed in the valve body 191, and a spring is installed between the valve core baffle 194 and the valve body 191. The valve core baffle 194 can close the internal channel of the valve body 191 through the spring force. The valve core baffle 194 and the support rod 193 are both equipped with magnets 195, and the magnet 195 on the valve core baffle 194 5 and the magnet 195 on the support rod 193 can generate a magnetic attraction. When oxygen supply is needed, the user can press the button 192. At this time, the button 192 drives the support rod 193 to move. At this time, the magnetic attraction between the two magnets 195 can overcome the elastic force of the spring and drive the valve core baffle 194 to move, thereby realizing the circulation of the airway inside the valve body 191. At this time, the gas in the oxygen supply bottle 100 can enter the breathing mask through the exhaust pipe 140 and the valve body 191, thereby realizing oxygen supply for the user, which is convenient for the user to perform breathing training. When the user increases the pressure on the button 192, as the support rod 193 and the valve core baffle 194 continue to move, the elastic force of the spring overcomes the magnetic attraction between the magnets 195, so that the support rod 193 is separated from the valve core baffle 194, and the valve core baffle 194 is reset by the elastic force of the spring, closing the airway in the valve body 191, thereby realizing intermittent oxygen supply. This is a prior art and will not be elaborated in detail.

[0039] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0040] The squeezing bag 1300 provided can change the curvature of the exhaust pipe 140 and the outlet direction of the exhaust pipe 140, so that the squeezing bag 1300 on the upper side is first expanded to a full state, and then the squeezing bag 1300 on the lower side is expanded to a full state, and the maximum expansion degrees of the squeezing bags 1300 at different upper and lower positions are different, so that the curvatures of the air distribution pipes 210 at the upper and lower positions are changed. The curvature of the air distribution pipe 210 at the lower side is smaller, and oxygen can retain more power when passing through the air distribution pipe 210, so that oxygen can enter the steam. The air distribution pipe 210 on the upper side has a larger curvature, which can provide more power for the rotation of the rotating body 150, and the oxygen in the air distribution pipe 210 loses more power in the air distribution pipe 210, so that the oxygen is closer to the axis of the oxygen supply bottle 100 after leaving the air distribution pipe 210, so that the bubbles formed by the oxygen in the distilled water are more uniform and will not affect each other, avoiding the oxygen bubbles from contacting and sticking to each other or merging into large bubbles, reducing the contact area between the oxygen bubbles and the distilled water, and affecting the humidification effect of the oxygen.

[0041] Embodiment 2: When the weather is relatively cold, the device can only humidify the oxygen but cannot heat the oxygen. This will cause the oxygen provided in the oxygen supply bottle 100 to be at a low temperature and humidified when the user performs breathing training. When the user performs breathing training for a long time, the discomfort in the respiratory tract will gradually increase, and may even cause damage to the user's respiratory tract. In order to avoid this problem, the prior art usually heats distilled water. However, when the distilled water is heated, the oxygen molecules in the water will obtain more thermal energy, which will speed up their movement and weaken the interaction force between molecules, making it easier to form bubbles and rise to the water surface. As the water temperature increases, the density of the water will decrease slightly, which will also help the oxygen bubbles float to the water surface faster, which may affect the humidification effect of the oxygen. In order to solve this problem, Figure 7-Figure 8 As shown, further improvements are made to the first embodiment:

[0042] Preferably, the oxygen supply bottle 100 is further provided with an electric heating wire 160, and each gas component further includes a second squeezing capsule 310 and a trigger capsule 320, wherein the second squeezing capsule 310 is installed on the inner bottom wall of the through hole 231 of the control board 230 in the gas component, and the second squeezing capsule 310 and the first squeezing capsule 300 are connected to each other through a connecting pipe, and the trigger capsule 320 is installed on the inner bottom wall of the through hole 231 of the control board 230 in the gas component, and the trigger capsule 3 20 wraps the extrusion capsule 2 310, and a medium layer 330 is formed between the trigger capsule 320 and the extrusion capsule 2 310. The medium layer 330 is filled with paraffin, and the melting point of the paraffin is 50-60 degrees Celsius. When the temperature rises to the point where the paraffin melts, the gas can enter the extrusion capsule 2 310 through the extrusion capsule 1 300 to expand the extrusion capsule 2 310. After the extrusion capsule 2 310 expands, it can squeeze the middle position of the gas distribution pipe 210 upward, so that the gas outlet end of the gas distribution pipe 210 moves downward.

[0043] When the weather is relatively cold, the electric heating wire 160 is energized to heat the distilled water in the oxygen supply bottle 100 to 55-70 degrees Celsius. When oxygen passes through the distilled water, it can be affected by the heated distilled water, thereby improving the comfort of the user performing breathing training when the temperature is relatively low. When the distilled water is heated, the heat can be transferred to the trigger bag 320. At this time, the paraffin in the medium layer 330 is melted, and the gas in the squeezing bag 1 300 can enter the squeezing bag 2 310. When the squeezing bag 2 310 expands, it can push the middle position of the gas distribution pipe 210 to move upward, thereby achieving the downward displacement of the gas outlet end of the gas distribution pipe 210, so that when oxygen enters the distilled water through the gas distribution pipe 210, it moves toward the bottom of the oxygen supply bottle 100, thereby accelerating the rate at which oxygen leaves the distilled water after the distilled water is heated, prolonging the time of oxygen in the distilled water, and maintaining the humidity of the oxygen on the premise of replenishing thermal energy to the oxygen molecules, thereby enhancing the comfort of the user during breathing training.

[0044] Preferably, the elastic coefficient of the extrusion bag 1 300 in the same-component gas component is greater than the elastic coefficient of the extrusion bag 2 310 .

[0045] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0046] By setting the trigger bag 320 and the squeeze bag 2 310, when the distilled water is heated, the heat can be transferred to the trigger bag 320, and the paraffin in the medium layer 330 is melted, and the gas in the squeeze bag 1 300 can enter the squeeze bag 2 310. When the squeeze bag 2 310 expands, it can push the middle position of the gas distribution pipe 210 to move upward, thereby realizing the downward displacement of the gas outlet end of the gas distribution pipe 210, so that when the oxygen enters the distilled water through the gas distribution pipe 210, it moves toward the bottom of the oxygen supply bottle 100, and then accelerates the rate at which the oxygen leaves the distilled water after the distilled water is heated to supplement it, prolonging the time of oxygen in the distilled water, and maintaining the humidity of the oxygen on the premise of replenishing heat energy to the oxygen molecules, thereby enhancing the comfort of the user during breathing training.

[0047] Embodiment 3: Since the rotating body 150 performs self-rotation during the oxygen supply operation, the downward gas distribution pipe 210 with the gas outlet end facing downward is susceptible to the resistance of distilled water when the rotating body 150 rotates, which may affect the direction of the gas outlet end of the gas distribution pipe 210. In order to solve this problem, further improvements are made to Embodiment 2:

[0048] Preferably, the dielectric layer 330 is also filled with metal powder.

[0049] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0050] By filling the medium layer 330 with metal powder, the hardness of the medium layer 330 can be increased. When the air distribution pipe 210 receives the resistance of distilled water, the medium layer 330 with hardness can produce a certain resistance to the resistance of distilled water, thereby reducing the possibility of deviation of the air outlet end of the air distribution pipe 210. In addition, the metal powder can also accelerate the transfer of heat, allowing the paraffin to respond to temperature changes more quickly, thereby ensuring the humidification and heating effect of oxygen, and further improving the comfort of the user in breathing training.

[0051] Embodiment 4: Since the gas distribution pipe group 200 located at the upper layer has a short travel in the distilled water after exhausting the oxygen, in order to speed up its temperature sensing after heating, further improvements are made to Embodiment 3:

[0052] Preferably, the amount of metal powder filled in the medium layer 330 in the upper air pipe group 200 is greater than the amount of metal powder filled in the medium layer 330 in the lower air pipe group 200, and the maximum expansion degree of the extrusion bag 2 310 in the upper air pipe group 200 is greater than the maximum expansion degree of the extrusion bag 2 310 in the lower air pipe group 200.

[0053] When the electric heating wire 160 is powered on and heated, the filling amount of metal powder in the medium layer 330 of the upper air distribution pipe group 200 is larger, and the content of paraffin is smaller. Therefore, the metal powder transfers heat faster, and the time for the paraffin to melt is reduced, which can make the air outlet end of the air distribution pipe 210 shift downward more quickly. On the other hand, the filling amount of metal powder in the medium layer 330 of the lower air distribution pipe group 200 is smaller, and the content of paraffin is higher, and its response speed to temperature is slower. Therefore, it can achieve uniform heating of oxygen, reduce the response time of oxygen heating, and further improve the comfort of the user during breathing training.

[0054] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0055] By changing the filling amount of metal powder in the upper and lower gas distribution pipe groups 200, uniform heating of oxygen is achieved, and the response time of oxygen heating is reduced, further improving the comfort of the user during breathing training.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
