Description

Technical Field

[0001] The invention belongs to the technical field of oxygen supply equipment, in particular to an oxygen humidification device for respiratory medicine. Background Art

[0002] The main function of the oxygen humidifier is to increase the humidity of the delivered oxygen to ensure that the oxygen inhaled by the patient is not too dry, thereby protecting the patient's respiratory tract and promoting the discharge of sputum. For elderly patients in poor physical condition, their own breathing is relatively weak, and the carbon dioxide exhaled by the patient is easily retained in the breathing mask and cannot be fully discharged. Therefore, in the subsequent oxygen supply process, the oxygen supplied later is mixed with part of the previous carbon dioxide and inhaled by the patient, resulting in the re-inhalation of carbon dioxide, which not only reduces the patient's oxygen intake, but also may cause the patient to have too high a concentration of carbon dioxide in the blood due to the inhalation of carbon dioxide, which has an adverse effect on the body.

[0003] In order to solve the problem of carbon dioxide being retained in the breathing mask, existing oxygen humidification devices usually use a one-way valve and an open or semi-open circuit to discharge the air exhaled by the patient. However, when the patient's breathing is weak, the flow rate of the exhaled air is low and the one-way valve may not be opened, so that the carbon dioxide still remains in the breathing mask, and the problem of re-inhalation of carbon dioxide cannot be prevented. Summary of the invention

[0004] The object of the present invention is to provide an oxygen humidification device for respiratory medicine to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention provides the following technical solution: an oxygen humidifier for respiratory medicine, comprising a fixing mechanism, the fixing mechanism comprising a mounting frame fixed on a wall, the mounting frame being slidably connected with a fixing frame, and further comprising:

[0006] A humidifying mechanism, the humidifying mechanism comprises a humidifying shell clamped in a fixed frame, a top cover is fixedly sleeved on the top of the humidifying shell, a partition is fixedly connected to the inside of the humidifying shell, a central shaft is rotatably installed at the center of the partition, a rotating block is arranged between the partition and the inner bottom surface of the humidifying shell, a plurality of fins are fixedly connected to the side of the rotating block, a spring bin is opened inside the rotating block, a driving spring is arranged in the spring bin, a one-way bearing is fixedly sleeved on the side of the central shaft located at the spring bin, and a fixed end of the driving spring is fixedly sleeved on the outer circumferential surface of the one-way bearing The humidifier housing is fixedly connected to the humidifier housing, the free end of the driving spring is fixedly connected to the inner side of the spring bin, the interior of the humidifier housing is also fixedly connected to an upper disk, the top end of the central axis passes through the upper disk, an oxygen chamber is provided inside the upper disk, a rotating wheel fixedly sleeved on the side of the central axis is provided in the oxygen chamber, an oxygen inlet pipe is fixedly connected to the top surface of the upper disk, an oxygen outlet is provided on the bottom surface of the oxygen chamber, an oxygen pipeline is fixedly connected to the oxygen outlet, the other end of the oxygen pipeline is located in the humidifier liquid bin between the bottom surface of the upper disk and the top surface of the partition, and the top surface of the upper disk is fixedly connected to the oxygen outlet pipe.

[0007] Preferably, the oxygen inlet pipe and the oxygen outlet pipe both pass through the top cover, the oxygen inlet pipe is connected to the oxygen supply device, and the oxygen outlet pipe connects the humidifying liquid tank with the breathing mask.

[0008] Preferably, a plurality of thumbwheels are evenly and fixedly sleeved on the side surface of the central axis, and the thumbwheels are located in the humidifying liquid cavity and are all located in the humidifying liquid.

[0009] Preferably, an air inlet and an air outlet communicating with the spring bin are fixedly connected to the outer side surface of the humidifying housing, the air inlet is communicated with the breathing mask, and a one-way valve is fixedly connected to the air outlet.

[0010] Preferably, when the central shaft rotates forward, the one-way bearing rotates together and causes the driving spring to store energy and tighten. When the driving spring releases energy, it rotates reversely and drives the rotating block to rotate. At this time, the driving spring cannot drive the central shaft to rotate reversely.

[0011] Preferably, when the rotating block rotates in the reverse direction, the gas in the breathing mask is extracted through the fins and discharged from the one-way valve, and the one-way valve prevents the outside air from being sucked into the clockwork bin from the air outlet.

[0012] Preferably, the lowermost end of the oxygen pipeline is located below the lowest thumbwheel, and when the thumbwheel rotates, the oxygen bubbles entering the humidifying liquid tank from the oxygen pipeline are broken.

[0013] Preferably, a heating sleeve is fixedly connected to the outer side of the humidifying shell, and the heating sleeve is responsible for heating the humidifying liquid in the humidifying liquid tank.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, by providing a central axis, a driving spring, a one-way bearing and a rotating wheel, when oxygen with a certain pressure is provided to the humidification mechanism through the oxygen inlet pipe, as the oxygen enters the oxygen chamber from the oxygen inlet pipe, the oxygen flow and the pressure generated by the transportation will drive the rotating wheel to rotate, thereby driving the central axis to rotate. When the kinetic energy provided by the oxygen cannot drive the central axis to rotate, a motor whose transmission shaft is coaxial with and connected to the central axis is provided on the humidification housing or the top cover to drive the central axis to rotate. At this time, under the transmission of the one-way bearing, the driving spring gradually accumulates energy. At this time, the resistance generated by the energy storage of the driving spring will reduce the flow rate of oxygen and increase its pressure. As the oxygen enters the humidification liquid through the oxygen pipeline, the oxygen with increased pressure can produce smaller bubbles in the water, so that the oxygen is fully humidified, thereby ensuring the humidification effect of the oxygen.

[0016] 2. After a single oxygen supply step is completed, as the supply of oxygen to the oxygen inlet tube is stopped, the central axis no longer rotates, and at the same time, the spring is driven to release its stored energy, driving the rotating block to rotate rapidly, and then the carbon dioxide and remaining oxygen in the breathing mask are drawn into the spring bin from the air inlet and out from the air outlet through the rotation of the rotating block and the fins. In this way, in a single breathing action, oxygen is supplied to the patient during his inhalation, and the carbon dioxide exhaled by the patient is drawn out of the breathing mask during his exhalation, thereby preventing the patient from inhaling carbon dioxide that was not discharged from the breathing mask in time during his next inhalation, resulting in reduced oxygen supply and high carbon dioxide concentration in the blood.

[0017] 3. Secondly, when the oxygen supply device inputs oxygen into the oxygen chamber and the humidifying liquid tank through the oxygen inlet pipe, as the oxygen drives the rotating wheel to rotate, the rotating wheel drives the central axis to rotate. At this time, the dial wheel connected to the central axis rotates together, thereby stirring and hitting the oxygen ejected from the oxygen pipeline. At this time, the larger oxygen bubbles are cut into multiple smaller bubbles by the dial wheel when being stirred and hit by the dial wheel, so that the oxygen is fully in contact with the humidifying liquid, thereby ensuring the humidification effect of the oxygen and preventing the dry oxygen from harming the patient's respiratory tract when inhaled.

[0018] 4. Finally, through the one-way valve, when the spring is driven to release energy to drive the rotating block to extract carbon dioxide and other gases in the breathing mask, as the rotating block rotates rapidly, carbon dioxide and other gases and remaining oxygen in the breathing mask are drawn into the spring bin, and then the one-way valve is opened and discharged into the surrounding environment. At this time, the remaining oxygen in the breathing mask and humidification mechanism is extracted and discharged into the surrounding environment, preventing excessive oxygen from being provided to the patient, causing oxygen poisoning, lung damage and other related problems, thereby ensuring the patient's health.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 5 As shown, an embodiment of the present invention provides an oxygen humidifier for respiratory medicine, including a fixing mechanism 1, the fixing mechanism 1 includes a mounting frame 11 fixed on a wall, a fixing frame 12 is slidably connected in the mounting frame 11, and further includes:

[0027] The humidifying mechanism 2 comprises a humidifying shell 21 clamped in the fixing frame 12, a top cover 22 is fixedly sleeved on the top of the humidifying shell 21, a partition 23 is fixedly connected to the inside of the humidifying shell 21, a central shaft 24 is rotatably installed at the center of the partition 23, a rotating block 25 is arranged between the partition 23 and the inner bottom surface of the humidifying shell 21, a plurality of fins 26 are fixedly connected to the side of the rotating block 25, a spring bin 27 is provided inside the rotating block 25, a driving spring 28 is arranged in the spring bin 27, a one-way bearing 29 is fixedly sleeved on the side of the central shaft 24 located at the side of the spring bin 27, a fixed end of the driving spring 28 is fixedly connected to the outer circumferential surface of the one-way bearing 29, and the driving spring 28 is driven by the central shaft 24. The free end of the spring 28 is fixedly connected to the inner side of the spring bin 27, and the interior of the humidifying shell 21 is also fixedly connected to an upper disk 210, the top end of the central axis 24 passes through the upper disk 210, an oxygen chamber 213 is provided inside the upper disk 210, a rotating wheel 216 fixedly sleeved on the side of the central axis 24 is provided in the oxygen chamber 213, an oxygen inlet pipe 211 is fixedly connected to the top surface of the upper disk 210, an oxygen outlet 214 is provided on the bottom surface of the oxygen chamber 213, an oxygen pipeline 215 is fixedly connected to the oxygen outlet 214, the other end of the oxygen pipeline 215 is located in the humidifying liquid bin between the bottom surface of the upper disk 210 and the top surface of the partition 23, and an oxygen outlet pipe 212 is fixedly connected to the top surface of the upper disk 210.

[0028] In the present invention, by providing the central shaft 24, the driving spring 28, the one-way bearing 29 and the rotating wheel 216, when oxygen with a certain pressure is provided to the humidifying mechanism 2 through the oxygen inlet pipe 211, as the oxygen enters the oxygen chamber 213 from the oxygen inlet pipe 211, the oxygen flow and the pressure generated by the delivery will drive the rotating wheel 216 to rotate, thereby driving the central shaft 24 to rotate. When the kinetic energy provided by the oxygen cannot drive the central shaft 24 to rotate, a motor having a transmission shaft coaxial with and connected to the central shaft 24 is provided on the humidifying housing 21 or the top cover 22 to drive the central shaft 24 to rotate. At this time, under the transmission of the one-way bearing 29, the driving spring 28 gradually accumulates energy. At this time, the resistance generated by the energy storage of the driving spring 28 will reduce the flow rate of oxygen and increase its pressure. As the oxygen enters the humidifying liquid through the oxygen pipeline 215, the oxygen with increased pressure is increased. The air can produce smaller bubbles in the water, so that the oxygen is fully humidified, thereby ensuring the humidification effect of the oxygen. After the single oxygen supply step is completed, as the oxygen is stopped from being delivered to the oxygen inlet tube 211, the central shaft 24 no longer rotates, and at the same time drives the spring 28 to release its stored energy, driving the rotating block 25 to rotate rapidly, and then through the rotation of the rotating block 25 and the fins 26, the carbon dioxide and the remaining oxygen in the breathing mask are drawn into the spring bin 27 from the air inlet 218 and leave from the air outlet 219, so that in a single breathing action, oxygen is supplied to the patient during his inhalation, and the carbon dioxide exhaled by the patient is drawn out of the breathing mask during the patient's exhalation, thereby preventing the patient from inhaling carbon dioxide that was not discharged from the breathing mask in time during his next inhalation, resulting in reduced oxygen supply and high carbon dioxide concentration in the blood.

[0029] Secondly, when the oxygen supply device inputs oxygen into the oxygen chamber 213 and the humidifying liquid tank through the oxygen inlet pipe 211, as the oxygen drives the rotating wheel 216 to rotate, the rotating wheel 216 drives the central shaft 24 to rotate. At this time, the dial wheel 217 connected to the central shaft 24 rotates together, thereby stirring and striking the oxygen ejected from the oxygen pipeline 215. At this time, the larger oxygen bubbles are cut into multiple smaller bubbles by the dial wheel 217 when being stirred and struck by the dial wheel 217, so that the oxygen is fully in contact with the humidifying liquid, thereby ensuring the humidification effect of the oxygen and preventing the dry oxygen from harming the patient's respiratory tract when being inhaled.

[0030] Finally, through the one-way valve 220, when the driving spring 28 releases energy to drive the rotating block 25 to extract the carbon dioxide and other gases in the breathing mask, as the rotating block 25 rotates rapidly, the carbon dioxide and other gases in the breathing mask and the remaining oxygen are all drawn into the spring bin 27, and then the one-way valve 220 is opened and discharged into the surrounding environment. At this time, the remaining oxygen in the breathing mask and the humidification mechanism 2 is extracted and discharged into the surrounding environment, preventing the patient from being provided with excessive oxygen, causing oxygen poisoning, lung damage and other related problems, thereby ensuring the patient's health.

[0031] Among them, the oxygen inlet pipe 211 and the oxygen outlet pipe 212 both penetrate the top cover 22, the oxygen inlet pipe 211 is connected to the oxygen supply device, the oxygen outlet pipe 212 connects the humidifying liquid tank with the breathing mask, and the side of the central axis 24 is evenly fixed with a plurality of dial wheels 217, the dial wheels 217 are located in the humidifying liquid cavity and are all located in the humidifying liquid, and the breathing mask is connected with two pipes, which are respectively connected to the oxygen outlet pipe 212 and the air inlet 218, so that the oxygen supply pipe and the pipe for extracting carbon dioxide are separated; the plurality of dial wheels 217 can break up larger oxygen bubbles in the oxygen supply link, thereby ensuring the humidification effect of oxygen.

[0032] Among them, the outer side of the humidifier shell 21 is fixedly connected with an air inlet 218 and an air outlet 219 which are communicated with the spring bin 27. The air inlet 218 is communicated with the breathing mask, and the air outlet 219 is fixedly connected with a one-way valve 220. When the central shaft 24 rotates forward, the one-way bearing 29 rotates together and causes the driving spring 28 to store energy and tighten. When the driving spring 28 releases energy, it rotates in the opposite direction and drives the rotating block 25 to rotate. At this time, the driving spring 28 cannot drive the central shaft 24 to rotate in the opposite direction. When the rotating block 25 rotates in the opposite direction, the gas in the breathing mask is extracted through the fins 26 and discharged from the one-way valve 220. The one-way valve 220 prevents outside air from being sucked into the spring bin 27 from the air outlet 219.

[0033] The arrangement of the one-way bearing 29 allows the driving spring 28 to be tightened by the one-way bearing 29 when the central shaft 24 is driven to rotate in the forward direction. After the central shaft 24 stops rotating, the driving spring 28 releases its stored energy, thereby causing the outer ring of the one-way bearing 29 to rotate in the reverse direction. At this time, due to the characteristics of the one-way bearing 29, the central shaft 24 will not be driven to rotate, thereby preventing the central shaft 24 from being rotated in the reverse direction and extracting the liquid in the humidification liquid tank, causing the humidification liquid to flow back into the oxygen input pipe.

[0034] The lowermost end of the oxygen pipe 215 is located below the lowermost dial wheel 217 , and when the dial wheel 217 rotates, the oxygen bubbles entering the humidifying liquid tank from the oxygen pipe 215 are broken.

[0035] The outer side of the humidifying housing 21 is fixedly connected with a heating sleeve 13 , and the heating sleeve 13 is responsible for heating the humidifying liquid in the humidifying liquid tank.

[0036] Working principle:

[0037] When using the device to humidify oxygen, first connect the oxygen supply pipe of the oxygen supply device to the oxygen inlet pipe 211, then connect the two pipes on the breathing mask to the oxygen outlet pipe 212 and the air inlet 218 respectively, and finally wear the breathing mask on the patient's face to complete the preliminary preparations.

[0038] In the subsequent oxygen supply process, as oxygen is injected into the humidification mechanism 2 by the oxygen supply device, the oxygen enters the oxygen chamber 213 through the oxygen inlet pipe 211, and then the oxygen enters the oxygen pipe 215 through the oxygen outlet 214. Subsequently, the oxygen leaves the oxygen pipe 215 and enters the humidification liquid in the humidification housing 21, so that the oxygen contacts the humidification liquid to humidify the oxygen. While the oxygen is being injected, the flow of oxygen drives the rotating wheel 216 to rotate, thereby driving the central shaft 24 to rotate in the forward direction. (If the flow of oxygen cannot drive the rotating wheel 216 to drive the central shaft 24 to rotate, the humidification housing 21 Or a motor is fixedly installed on the top cover 22, so that the output shaft of the motor is connected to the central shaft 24, and the motor is used to drive the central shaft 24 to rotate in the positive direction.) As the central shaft 24 rotates forward, the central shaft 24 stores energy and tightens the driving spring 28 through the one-way bearing 29. During the rotation of the central shaft 24, the dial wheel 217 rotates together. At this time, under the rotation of the dial wheel 217, the dial wheel 217 will come into contact with the large oxygen bubble in the humidifying liquid, thereby breaking the bubble, so that the large bubble is divided into multiple small bubbles, and as the oxygen enters the breathing mask from the oxygen outlet pipe 212, it is inhaled by the patient's inhalation action.

[0039] As the patient enters the exhalation phase, oxygen supply is stopped and the central shaft 24 no longer rotates, i.e., the driving spring 28 is no longer tightened to store energy, so that the driving spring 28 releases its stored energy and rotates in the opposite direction, thereby driving the rotating block 25 to reverse. The reverse rotation of the rotating block 25 will extract the carbon dioxide in the breathing mask through the pipe connected to the breathing mask through the air inlet 218 and discharge it to the surrounding environment.

[0040] After the exhalation phase is finished, the inhalation phase begins, and the above steps are repeated in a cycle to fully humidify the oxygen supplied to the patient and extract the carbon dioxide produced by the patient's exhalation.
