Description

Technical Field

[0001] This invention relates to the field of medical respiratory device technology, and in particular to an intelligent controllable nebulizer oxygen inhalation integrated device. Background Technology

[0002] During the use of medical breathing devices, patients not only need to receive oxygen inhalation but also require intermittent nebulization therapy. Although existing integrated nebulization and oxygen inhalation devices are equipped with buttons to switch between oxygen inhalation and nebulization, nurses need to manually time and switch modes. Since nurses often take care of multiple patients, there is a shortage of manpower, making it impossible to control the duration of oxygen inhalation and nebulization in a timely manner. This leads to inaccurate timing of oxygen inhalation and nebulization therapy, affecting the treatment effect. Moreover, manually switching modes not only increases the workload of nurses but also easily leads to human error. Therefore, there is a need to propose an intelligent controllable integrated nebulization and oxygen inhalation device.

[0003] A medical oxygen supply controller, as proposed in CN202422031507.5, includes a ventilation seat with a flow meter and a humidification bottle at each end, a flow regulating valve on the ventilation seat, and a connecting seat between the ventilation seat and the humidification bottle; an oxygen supply tube connected to the ventilation seat; and a switching valve passing through the middle of the connecting seat, with an oxygen inlet and a nebulization port at each end, a through hole in the middle of the switching valve, and the switching valve slidably connected to the connecting seat. When the switching valve moves laterally towards the oxygen inlet, it switches the oxygen supply tube to connect with the nebulization port; when the switching valve moves laterally towards the nebulization port, it switches the oxygen supply tube to connect sequentially with the through hole, the humidification bottle, and the oxygen inlet. This invention uses a switching valve to switch the airflow channel, making it simple to operate and convenient to switch between oxygen supply and nebulization modes. However, it requires manual switching and fails to solve the aforementioned problem.

[0004] The present invention can achieve intelligent control of the flow control component and the switching component through the intelligent control component, automatically control the duration of oxygen inhalation and nebulization, and reduce the workload of nursing staff.

[0016] Beneficial effects The present invention has the following beneficial effects: (1) Intelligent control, precise and efficient -- This intelligent control type nebulizer oxygen inhalation device can accurately control the duration of oxygen inhalation and nebulizer treatment through the timing function integrated in the second circuit board of the intelligent control component. There is no need for nursing staff to manually time and switch modes, which greatly improves the accuracy of treatment time and ensures that patients receive more effective treatment. This not only solves the problem of insufficient nursing staff causing the inability to control the time in time, but also avoids human operation errors and reduces the adverse effects on the treatment effect.

[0017] (2) Multi-component collaboration and diverse functions: The flow control component, intelligent control component and switching component work together to achieve precise control of oxygen flow and intelligent switching of modes. The flow control component controls the push rod through the motor, thereby adjusting the position of the valve core to achieve precise adjustment of oxygen flow; the switching component can flexibly switch between nebulization mode and oxygen inhalation mode to meet the different treatment needs of patients.

[0018] (3) Reasonable design and easy to use -- The special design of the locking edge on the push ring and the flange on the humidification bottle connecting component allows the humidification bottle to be installed and disassembled with one hand, making the operation simple and convenient and improving nursing efficiency. At the same time, the first and second connecting ports are international interfaces of different standards, which can adapt to different specifications of wall-mounted oxygen interfaces, enhancing the versatility and applicability of the equipment. In addition, the limiting tube and sealing tube are made of transparent material. With the ruler sticker on the sealing tube and the Hall element and light-emitting diode on the first circuit board, it is easy for medical staff to intuitively observe the position of the magnetic bead, thereby accurately indicating the oxygen flow rate, facilitating the monitoring and adjustment of the oxygen flow rate, and providing patients with a more comfortable and effective oxygen inhalation and nebulization treatment experience, making it easy to operate and adjust.

[0019] (4) Safe and reliable, stable performance -- The equipment is designed with safety and stability in mind. The electromagnetic expansion valve is equipped with a corresponding freewheeling diode to prevent back electromotive force from burning out the circuit. The connection between each component is tight and the sealing performance is good, ensuring the normal delivery of oxygen and the stable operation of the equipment. At the same time, the diaphragm in the humidification component is made of elastic material, which can play a certain role in buffering and protection, and extend the service life of the equipment. Moreover, the elastic diaphragm on the inner side of the upper end of the bottle helps to maintain the sealing and stability of the bottle. With the setting of the gas collection hood, when the humidification component is tilted, the liquid in the bottle is not easy to flow out from the oxygen inhalation port due to the bending of the diaphragm, ensuring the safety of the patient. In addition, through the cooperation of the second spring and the sleeve, when the oxygen supply is stopped, the sleeve will also be reset by the second spring, thereby preventing liquid from entering the humidification tube and ensuring the safety of each device.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 - Figure 18 This invention provides a technical solution: an intelligent controllable nebulizer oxygen inhalation integrated device includes a flow control component 1, an intelligent control component 2, and a switching component 3.

The switching component 3 is fixed below the flow control component 1 for switching between nebulization mode and oxygen inhalation mode.

[0025] like Figure 4 - Figure 10As shown, the intelligent controllable nebulizer oxygen inhalation integrated device includes a flow control component 1. The flow control component 1 includes a first housing 101, a first valve body 102, a second valve body 112, a nozzle 109, a limiting tube 110, a magnetic bead 111, a valve core 114, a push rod 115, a motor 116, a sealing tube 119, and a first circuit board 120.

The first valve body 102 is fixed inside the first housing 101, the second valve body 112 is fixed inside the first valve body 102, the nozzle 109 is fixed above the first valve body 102, the limiting tube 110 is fixed above the nozzle 109, the magnetic bead 111 is disposed inside the limiting tube 110, and the valve core 114 is installed on the second valve body 112. Inside, push rod 115 is installed inside the second valve body 112, motor 116 is fixed to the side of the first outer shell 101, sealing tube 119 is rotatably installed above the first valve body 102 via sealing bearing 123, first circuit board 120 is located inside the sealing tube 119, on the side of the limiting tube 110, the first circuit board 120 is connected to the intelligent control component 2 by wires for energy and data transmission, the first valve body 102 is provided with air inlet pipe 105, central pipe 106 and flow limiting pipe 108, the air inlet pipe 105 consists of two pipes, the two air inlet pipes 105 are respectively connected to the first connection port 103 and the second connection port 104, and connected to the central pipe 106, the flow limiting pipe 108 is connected to the central pipe 106, and the front end of the second valve body 112 is provided with A first sealing ring 113 is provided, and the valve core 114 is slidably mounted on the first sealing ring 113. The front end of the valve core 114 is located inside the central pipe 106, and the rear end of the valve core 114 is located inside the second valve body 112. The front end of the valve core 114 is tapered, which can block the flow limiting pipe 108 after contacting it, thereby controlling the oxygen flow. The rear end of the valve core 114 is rotatably mounted on the push rod 115. The rear end of the push rod 115 is provided with a first sliding groove 117, and the outer side of the rear end of the push rod 115 is provided with a thread. The push rod 115 is slidably mounted on the output shaft of the motor 116 through the first sliding groove 117. The push rod 115 is also threadedly mounted on the inner side of the second valve body 112. The nozzle 109 has a through hole and is connected to the flow limiting pipe 116. The flow tube 108 is connected. The limiting tube 110 and the sealing tube 119 are made of transparent material, making it easy to observe the position of the magnetic bead 111. The upper inner side of the sealing tube 119 is provided with a buffer block 122 made of elastic material, located above the limiting tube 110, to limit the magnetic bead 111. The buffer block 122 is a convex hemispherical shell shape with multiple through holes for oxygen flow and to prevent blockage of the limiting tube 110. The first circuit board 120 is provided with evenly distributed Hall elements and light-emitting diodes. The position, height, and number of Hall elements and light-emitting diodes are corresponding. The sealing tube 119 is provided with a scale sticker 121, which corresponds to the position and height of the Hall elements and light-emitting diodes, to indicate the oxygen flow rate.The first valve body 102 is provided with an outlet pipe 118, which is inclined. The upper end of the outlet pipe 118 is located between the limiting pipe 110 and the sealing pipe 119, and the lower end of the outlet pipe 118 is located at the center of the first valve body 102. The first connection port 103 and the second connection port 104 are international interfaces of different standards to adapt to different specifications of wall-mounted oxygen interfaces. The inlet pipe 105 is inclined, with the end connected to the first connection port 103 and the second connection port 104 being lower and the end connected to the central pipe 106 being higher. A ball bearing 107 is provided inside the inlet pipe 105.

[0026] More preferably, the light-emitting diodes on the first circuit board 120 are set with at least two different colors. The uppermost light-emitting diode is set with conspicuous warning colors such as yellow and red and is kept constantly lit to indicate the upper limit of oxygen flow. The remaining light-emitting diodes are set with non-conspicuous indicator colors such as white and green to indicate the current value of oxygen flow. The Hall element on the first circuit board 120 is an all-polar Hall element, which facilitates accurate sensing and detection of the position of the magnetic bead 111.

[0027] In a specific embodiment: during connection, the corresponding first connection port 103 or second connection port 104 is selected according to the specifications of the wall-mounted oxygen interface, so that the atomizing oxygen inhalation integrated device is fixed to the wall. During startup and adjustment, the motor 116 is started by the control of the intelligent control component 2, which drives the push rod 115. The push rod 115 rotates in the second valve body 112 through the thread, thereby driving the valve core 114 to move back and forth, controlling the gap between the front end of the valve core 114 and the front end of the flow limiting tube 108, thereby controlling the oxygen flow rate. In use, oxygen enters the intake pipe 105 through the first connection port 103 or the second connection port 104, and pushes the ball 107, thereby entering the central pipe 106 through the intake pipe 105. Then, it enters the flow limiting pipe 108 through the gap between the front end of the control valve core 114 and the front end of the flow limiting pipe 108, and then enters the nozzle 109 through the flow limiting pipe 108. It is then ejected from the nozzle 109, thereby pushing the magnetic bead 111 to move upward. Then, the oxygen enters the sealing pipe 119 through the through hole on the buffer block 122 from the limiting pipe 110, and then is discharged through the outlet pipe 118. During the process, since only one end of the air intake pipe 105 is inlet, taking the first connection port 103 as an example, the ball bearing 107 of the other end of the air intake pipe 105 will block the connection between the air intake pipe 105 and the second connection port 104 due to gravity. At the same time, due to the positive pressure in the central pipe 106, the ball bearing 107 will press more tightly to block the connection between the air intake pipe 105 and the second connection port 104, thereby preventing oxygen leakage.

[0028] When the magnetic bead 111 moves upward, the Hall element on the first circuit board 120 senses the height position of the magnetic bead 111 and sends a feedback signal to the intelligent control component 2. The position of the valve core 114 is adjusted in real time according to the usage requirements to change the oxygen flow rate and make the corresponding LED light up. The real-time oxygen flow rate can be observed intuitively through the transparent limit tube 110 and the sealing tube 119.

[0029] like Figure 3 and Figure 4 As shown, the intelligent control type atomizing oxygen inhalation integrated device includes an intelligent control component 2. The intelligent control component 2 includes a second housing 201, a second circuit board 202, a display screen 203, and a battery 204. The second housing 201 is fixed to the side of the first housing 101 by a clamp 205. The second circuit board 202 and the battery 204 are installed inside the second housing 201. The display screen 203 is installed at the front end of the second housing 201. The display screen 203 and the battery 204 are connected to the second circuit board 202 by a connecting wire. The second circuit board 202 integrates power management, network communication, timing, display, and load drive functions to realize mobile phone and remote system control. It is also equipped with a Type-C female charging interface. The integrated power management function realizes the charging and discharging of the battery 204. It is connected to the first circuit board 120 by a wire for data transmission and is also connected to the motor 116 by a wire to control the start and stop of the motor 116.

[0030] In a specific embodiment: the second circuit board 202 uses an ESP32-WROOM-32 as the main controller, integrates Wi-Fi + Bluetooth dual-mode communication, and has a built-in 32-bit MCU and RTC real-time clock (timing function). When in use, it controls the motor 116 to work according to the usage requirements, thereby adjusting the oxygen flow rate. When the patient needs a larger oxygen flow rate, he / she can send a command through a mobile phone or remote system. After receiving the command, the second circuit board 202 transmits a signal to the motor 116 through a wire to control the working time of the motor 116, thereby increasing the gap between the front end of the valve core 114 and the front end of the flow limiting tube 108, and increasing the oxygen flow rate.

[0031] Furthermore, during the adjustment process, the second circuit board 202, through its integrated display function, feeds back the oxygen flow data detected by the first circuit board 120 to the display screen 203 in real time, allowing users to intuitively understand the working status of the equipment. At the same time, the timing function records the usage time of the equipment, making it convenient for medical staff or users to keep track of the usage time and ensure the standardization and effectiveness of the treatment. In addition, the network communication function of the equipment can also upload the usage data to a remote system, making it convenient for doctors to remotely monitor the patient's usage and provide timely professional guidance and suggestions.

A second spring 314 is installed between the movable ring 313 and the sliding ring. A third sliding groove 315 is opened on the movable ring 313, and the third sliding groove 315 is inclined. A limiting rod 312 is installed, and a second sliding groove 310 corresponding to the limiting rod 312 is provided on the humidification bottle connecting assembly 304. The limiting rod 312 is slidably installed in the second sliding groove 310. A pushing ring 316 is also fitted on the humidification bottle connecting assembly 304. The pushing ring 316 is located outside the movable ring 313. A boss 318 is provided at the lower end of the pushing ring 316. The boss 318 is located below the movable ring 313. A retaining ring 311 is provided on the humidification bottle connecting assembly 304. The retaining ring 311 is located below the boss 318. The upper end of the pushing ring 316 has retaining flanges 317 on both sides. A third sealing ring 319 is fixed inside the humidification bottle connecting assembly 304.

[0033] In a specific embodiment: during use, the third valve body 301 is fixed below the first outer shell 101, so that the straight hole 321 is connected to the air outlet pipe 118. The humidification bottle connecting assembly 304 is equipped with the humidification assembly 4 or the external humidification bottle through the third sealing ring 319, and is fixed by the limiting rod 312 to prevent it from falling off. In the initial position (oxygen inhalation), oxygen enters the shunt tube 302 through the straight hole 321. Due to the obstruction of the second sealing ring 309 in the middle, the oxygen can only enter the humidification bottle connection assembly 304 through the annular groove 308, and then enter the humidification assembly 4 or the external humidification bottle to humidify the oxygen, making it easier for the patient to inhale oxygen. During adjustment (atomization), oxygen enters the distributor pipe 302 through the straight hole 321. Under the control of the intelligent control component 2, the telescopic rod of the electromagnetic telescopic valve 307 extends, thereby pushing the piston rod 305 and compressing the first spring 306. This causes the annular groove 308 to move to the atomization interface 303 and the straight hole 321. At this time, the second sealing ring 309 in the middle is located on the left side of the atomization interface 303, and the second sealing ring 309 on the right side is located between the straight hole 321 and the humidification bottle connection component 304. This allows oxygen to enter the atomization interface 303 through the annular groove 308, thus switching to the atomization mode.

[0034] When removing the humidification component 4 or the external humidification bottle, the push ring 316 is moved upward, thereby driving the movable ring 313 and compressing the second spring 314. At the same time, the third sliding groove 315 drives the limiting rod 312 to move, thereby causing the limiting rod 312 to slide in the second sliding groove 310, thus disengaging the limiting rod 312 from the humidification component 4 or the external humidification bottle, canceling the limitation on the humidification component 4 or the external humidification bottle. Then, the push ring 316 is rotated, causing the retaining edge 317 on the push ring 316 to rotate above the flange 325, thereby limiting the push ring 316 and preventing the push ring 316 from resetting through the second spring 314. Then, the humidification component 4 or the external humidification bottle is pulled down, thereby removing the humidification component 4 or the external humidification bottle. The entire process can be operated with one hand, while traditional nebulizer oxygen inhalation devices require one hand to move the push ring 316 upward and the other hand to pull down the humidification bottle. In comparison, this integrated nebulizer oxygen inhalation device is much easier to operate.

[0035] like Figure 3 , Figure 4 , Figure 16 , Figure 17 and Figure 18As shown, the intelligent controllable nebulizer oxygen inhalation integrated device also includes a humidification component 4. The humidification component 4 includes an upper cover 401, a humidification tube 405, and a bottle body 406. The upper cover 401 has a connecting nozzle 402 for connecting to the humidification bottle connecting component 304. The upper cover 401 has a gas collecting hood 403 below it. The upper cover 401 also has an oxygen inhalation interface 404, the lower end of which is connected to the gas collecting hood 403. The humidification tube 405 is fixed below the upper cover 401. The upper end of the humidification tube 405 is connected to the connecting nozzle 402, and the lower end of the humidification tube 405 is slidably fitted with a sleeve. A third spring 413 is provided between the lower end of the tube 408 and the sleeve 408. The lower end of the humidification tube 405 has an exhaust hole 407. The humidification tube 405 has a buckle 411 to limit the sleeve 408. The outer side of the sleeve 408 has a humidification ring 409 and a vent hole 410. The upper outer side of the bottle body 406 has a threaded structure. The bottle body 406 is installed and fixed below the top cover 401 by the threaded structure. The inner side of the upper end of the bottle body 406 has a diaphragm 414. The diaphragm 414 is made of elastic material and is annular.

[0036] In a specific embodiment: during use, the top cover 401 is separated from the bottle body 406, distilled water is added to the bottle body 406, then the bottle body 406 is connected to the top cover 401, and the gas collecting hood 403 is secured in the diaphragm 414, causing the diaphragm 414 to deform and bend, as shown. Figure 16 As shown, the humidification assembly 4 is then connected to the humidification bottle connection assembly 304 via the connection nozzle 402, allowing oxygen to enter the humidification tube 405. Due to the air pressure, the oxygen pushes the sleeve 408 and stretches the third spring 413, thereby allowing the oxygen to enter the humidification ring 409 through the vent 410 and disperse into the water through the humidification ring 409 for humidification. Then, the oxygen leaves the liquid surface and enters the gas collection hood 403, and is discharged through the oxygen inhalation port 404 for patient use.

[0037] Working principle: Flow control component 1: First, select the corresponding connection port according to the wall-mounted oxygen interface specifications and fix the device to the wall. During startup and adjustment, intelligent control component 2 controls motor 116 to operate. Motor 116 drives push rod 115 to rotate within the second valve body 112 via a thread, thereby driving valve core 114 to move back and forth, changing the gap between the front end of valve core 114 and the front end of flow restrictor 108, thus controlling the oxygen flow rate. During use, oxygen enters the inlet pipe 105 from the connection port, pushes ball bearing 107 into the central pipe 106, and then passes through valve core 114... 4 enters the flow-limiting tube 108 through the gap between the flow-limiting tube 108 and the flow-limiting tube 108, and then is ejected from the nozzle 109, pushing the magnetic bead 111 to move upward. Oxygen enters the sealing tube 119 through the through hole on the buffer block 122 from the limiting tube 110, and finally is discharged through the outlet tube 118. During this period, the Hall element on the first circuit board 120 senses the height position of the magnetic bead 111 and feeds back the signal to the intelligent control component 2. The intelligent control component 2 adjusts the position of the valve core 114 in real time according to the needs to change the oxygen flow rate. At the same time, the corresponding LED lights up, so that the user can intuitively observe the real-time oxygen flow rate.

[0038] Regarding the intelligent control component 2: The ESP32-WROOM-32 is the main controller, integrating Wi-Fi + Bluetooth dual-mode communication, power management, network communication, timing, display, and load driving functions. During use, it controls the motor 116 to adjust the oxygen flow rate as needed. When a patient requires a higher oxygen flow rate, a command can be sent via mobile phone or remote system. Upon receiving this command, the second circuit board 202 controls the operating time of the motor 116, increasing the gap between the front end of the valve core 114 and the front end of the flow restrictor 108 to improve the oxygen flow rate. During adjustment, the second circuit board 202 provides real-time feedback of the current oxygen flow rate data to the display screen 203. The timing function records the device usage time, and the network communication function uploads the usage data to the remote system for convenient remote monitoring and guidance by doctors.

[0039] Regarding the switching component 3: When initially in oxygen inhalation mode, oxygen enters the shunt tube 302 through the straight hole 321. Due to the obstruction of the second sealing ring 309 in the middle, the oxygen can only enter the humidification bottle connecting component 304 through the annular groove 308, and then enter the humidification component 4 or the external humidification bottle to humidify the oxygen for the patient to inhale. When it is necessary to switch to nebulization mode, the intelligent control component 2 controls the extension rod of the electromagnetic telescopic valve 307 to extend, push the piston rod 305 to compress the first spring 306, and move the annular groove 308 to the nebulization interface 303 and the straight hole 321. At this time, oxygen enters the nebulization interface 303 through the annular groove 308, completing the mode switching.

[0040] Regarding the humidification component 4: Before use, first separate the top cover 401 from the bottle body 406, add distilled water to the bottle body 406, then connect the bottle body 406 to the top cover 401, so that the gas collection hood 403 is locked in the diaphragm 414 and the diaphragm 414 is deformed and bent. Then, the humidification component 4 is connected to the humidification bottle connection component 304 through the connection nozzle 402, oxygen is introduced into the humidification tube 405, the air pressure pushes the sleeve 408 to stretch the third spring 413, and the oxygen enters the humidification ring 409 through the vent hole 410 and is dispersed into the water to achieve oxygen humidification. The humidified oxygen leaves the liquid surface and enters the gas collection hood 403, and finally is discharged through the oxygen inhalation interface 404 for the patient to use.
