Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a respiratory training device for respiratory nursing. Background Technology

[0002] The respiratory department includes respiratory medicine and respiratory surgery. Currently, some patients in the respiratory department often use respiratory trainers for rehabilitation training of their breathing ability. A respiratory trainer is an active breathing exercise device that can train the respiratory muscle groups through the principle of resistance.

[0003] A respiratory training device for rehabilitation, disclosed in CN215741676U, relates to the field of respiratory training equipment technology. It includes a support base and a respiratory trainer. A main pipe is installed inside the arc-shaped trainer, with its left end extending through the arc-shaped trainer and connecting to a mouthpiece. Multiple respiratory training cylinders are equidistantly arranged above the trainer, each with an air outlet at its top. Gas flows through the main pipe, pushing a float upwards within the cylinder. A telescopic spring provides damping, thus achieving the respiratory training effect. Pulling a pull ring causes a reset rod and a sealing plate to move up and down via a support plate. The sealing plate seals the main pipe, and a positioning rod engages with a positioning hole to fix the position of the sealing plate.

[0004] The above-mentioned patent still has the following shortcomings: In daily use, after the patient finishes breathing training, the mouthpiece needs to be removed from the main tube for disinfection and cleaning so that it can be used by other patients. However, after the above-mentioned patent is used, the breathing mask needs to be manually disassembled and replaced. Some patients are prone to disassembly errors and the operation is troublesome when disassembling the breathing mask. It also takes a certain amount of time and affects the use of other patients.

[0005] Based on this, in order to solve the aforementioned technical defects, a respiratory training device for respiratory nursing is proposed. Summary of the Invention

[0006] To overcome the drawbacks of the aforementioned patents, which require manual disassembly of the mouthpiece, making the operation inconvenient and time-consuming, this invention provides a respiratory training device for respiratory nursing.

Gear rings are connected to the rear sides of both rotating cylinders. The gear rings are close to the rack frame and can engage with it. The engaging assembly is provided on the connecting cylinder.

[0008] As a further preferred embodiment, the support assembly includes an adjusting frame, a guide frame, a handle, and a support rod. The adjusting frame is slidably connected to the rear side of the support frame, and the guide frame is slidably connected to the front side of the support frame. A handle is connected to the upper side of the guide frame. A damper is installed between the adjusting frame and the support frame, and a damper is also installed between the guide frame and the support frame. The support rod is rotatably connected to the rear side of the guide frame. The support rod is connected to two flow pipes and two connecting cylinders. A motor is installed on the rear side of the guide frame. An electric valve is rotatably connected to the adjusting frame. The front end of the telescopic tube passes through the adjusting frame and is rotatably engaged with the inside of the electric valve. A rack frame is connected to the lower side of the adjusting frame.

[0009] As a further preferred embodiment, the auxiliary components include an adjusting valve, an indicator light, a float, a switch, and a return spring. An adjusting valve for adjusting breathing resistance is installed on the air inlet end of the breathing trainer and is fixed to the base plate. A float is slidably installed inside each connecting tube of the breathing trainer, and a switch is slidably connected to the top of each connecting tube. A return spring is connected between the switch and the inside of each connecting tube. An indicator light is installed on the top of each connecting tube. The indicator light and the switch are electrically connected to the controller. When the float moves upward and presses against the switch, the corresponding indicator light will be illuminated by the controller.

[0010] As a further preferred embodiment, the locking assembly includes a sliding ring, a compression spring, a locking block, a limiting rod, a knob, and a spring. Sliding rings are slidably connected to the rear side of the connecting cylinder, with the sliding rings located on the outer side of the rotating cylinder on the same side. Compression springs are connected between the sliding rings and the interior of the connecting cylinder on the same side. Reference grooves are symmetrically opened on the front side of the rotating cylinder. Locking blocks are symmetrically connected inside the mouthpiece sleeve. Limiting rods are symmetrically connected vertically to the outer side of the connecting cylinder, and the limiting rods are slidably locked into the mouthpiece sleeve. A knob is connected to the rear side of the rotating cylinder, and springs are connected to the lower and right sides of the knobs, with the springs contacting and engaging with the support rods.

[0011] As a further preferred option, the included angle between the two springs on each knob is 90 degrees.

[0012] As a further preferred embodiment, when the mouthpiece sleeve is in the locked state, the position of the locking block on the X-axis and the position of the reference groove on the Y-axis are such that the locking block contacts and engages with the reference groove, while the locking block engages and engages with the rotating drum.

[0013] As a further preferred embodiment, the training device also includes a fixed block, a pushing block, a connecting frame, and a squeezing block. The fixed block is connected to the upper side of the adjusting frame, the pushing block is connected to the bottom of the motor, and the connecting frame is connected to both flow pipes. The squeezing block is slidably connected to the connecting frame. The squeezing block is in contact with the flow pipe, and the part of the flow pipe in contact with the squeezing block is a flexible tube. The pushing block and the squeezing block are in contact and cooperate. The outer walls of both the pushing block and the squeezing block are arc-shaped. The pushing block pushes the squeezing block to squeeze the flexible part of the flow pipe, which can prevent the gas from flowing in the flow pipe.

[0014] As a further preferred embodiment, the training device also includes a guide plate and a collection frame, with the guide plate connected to the middle of the support frame, and a collection frame for collecting mouthpiece sleeves placed on the bottom plate to the left of the guide plate.

[0015] The present invention has the following advantages: 1. The motor drives the upper and lower connecting cylinders to rotate 180 degrees to change their positions. The mouthpiece sleeve rotates with it. Through the cooperation of the gear ring and the rack frame, the connecting cylinder can be rotated, so that the connecting cylinder can loosen the mouthpiece sleeve. The mouthpiece sleeve will then automatically pop out and be removed, thus completing the automatic disassembly of the mouthpiece sleeve, which provides convenience for patients and saves disassembly time. 2. The disassembled mouthpiece cover can fall into the collection box through the guide plate, which makes it convenient for staff to clean the mouthpiece cover in a unified manner and avoids the disassembled mouthpiece cover being discarded at will. 3. The adjustable frame and guide frame can be adjusted according to the patient's height, allowing the patient to complete the training in a standing or sitting position, making it more flexible to use.

[0027] Example: A respiratory training device for respiratory nursing, such as... Figures 1-9 As shown, the device includes a base plate 1, a breathing trainer 101, a support frame 103, a controller 104, a telescopic tube 106, an electric valve 204, a motor 205, a flow tube 206, a connecting tube 207, a mouthpiece sleeve 208, a rotating drum 301, a rack and pinion frame 501, a gear ring 502, a support assembly, an auxiliary assembly, and a snap-fit ​​assembly. The breathing trainer 101 is bolted to the rear top of the base plate 1. The breathing trainer 101 is existing technology and consists of three connecting tubes and an auxiliary assembly. The three connecting tubes are connected by pipes. An auxiliary assembly is provided on the breathing trainer 101. The support frame 103 is bolted to the front right side of the base plate 1. The controller 104 is mounted on the front side of the support frame 103. The telescopic tube 106 is detachably connected to the top of the rightmost connecting tube of the breathing trainer 101. A support assembly is provided on the support frame 103, and a motor 205 is mounted on the support assembly. 5. An electric valve 204 is connected to the output shaft of the motor 205. The electric valve 204 is a double-flow valve. Both ends of the electric valve 204 are connected to flow pipes 206. The front end of the telescopic pipe 106 passes through the support assembly and is rotatably snapped into the inside of the electric valve 204. The telescopic pipe 106 communicates with the two flow pipes 206 through the electric valve 204. Both the upper and lower sides of the support assembly are connected to connecting cylinders 207. The outer ends of the two flow pipes 206 are connected to the connecting cylinders 207 on the same side. The front side of the connecting cylinders 207 is snapped with a mouthpiece sleeve 208. The connecting cylinders 207 are rotatably connected with rotating cylinders 301. The flow pipes 206 communicate with the rotating cylinders 301. A rack frame 501 is connected to the support assembly. The rear side of the two rotating cylinders 301 is connected to a gear ring 502. The gear ring 502 is close to the rack frame 501 and can mesh with the rack frame 501. The connecting cylinder 207 is provided with a snapping assembly for fixing the mouthpiece sleeve 208.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, the support assembly includes an adjusting frame 201, a guide frame 202, a handle 7, and a support rod 203. The adjusting frame 201 is slidably connected to the rear side of the support frame 103, and the guide frame 202 is slidably connected to the front side of the support frame 103. The handle 7 is snapped onto the upper side of the guide frame 202. A damper is installed between the adjusting frame 201 and the support frame 103, and a damper is also installed between the guide frame 202 and the support frame 103. The support rod 203 is rotatably connected to the rear side of the guide frame 202. The support rod 203 is connected to two flow pipes 206 and two connecting cylinders 207. A motor 205 is installed on the rear side of the guide frame 202. An electric valve 204 is rotatably connected to the adjusting frame 201. The front end of the telescopic tube 106 passes through the adjusting frame 201 and is rotatably snapped into the electric valve 204. A rack frame 501 is connected to the lower side of the adjusting frame 201.

[0029] like Figures 1-3 As shown, the auxiliary components include a regulating valve 102, an indicator light 105, a float 107, a switch 108, and a return spring 109. A regulating valve 102 for adjusting breathing resistance is installed on the air inlet end of the breathing trainer 101. The regulating valve 102 is fixed on the base plate 1. A float 107 is slidably installed inside each connecting tube on the breathing trainer 101. A switch 108 is slidably connected to the top of each connecting tube. A return spring 109 is connected between the switch 108 and the inside of each connecting tube. An indicator light 105 for indication is installed on the top of each connecting tube. The indicator light 105 and the switch 108 are electrically connected to the controller 104. When the float 107 moves upward and presses against the switch 108, the controller 104 will control the corresponding indicator light 105 to light up.

[0030] like Figures 5-7 As shown, the locking assembly includes a sliding ring 302, a compression spring 303, a locking block 305, a limiting rod 306, a knob 307, and a spring 308. Sliding rings 302 are slidably connected to the rear side of the connecting cylinder 207. The sliding rings 302 are located outside the rotating cylinder 301 on the same side. Compression springs 303 are connected between the sliding rings 302 and the interior of the connecting cylinder 207 on the same side. Reference grooves 304 are symmetrically opened on the front side of the rotating cylinder 301. Locking blocks 305 are symmetrically connected inside the mouthpiece sleeve 208. When the mouthpiece sleeve 208 is in the locked state, the position of the locking block 305 on the X-axis and the position of the reference groove 304 on the Y-axis are determined by aligning the locking block 305 with the reference groove 304. The mouthpiece sleeve 208 is snapped onto the connecting cylinder 207. The mouthpiece sleeve 208 will compress the sliding ring 302. Rotating the mouthpiece sleeve 208 will cause the locking block 305 to be offset from the reference groove 304, thus fixing the mouthpiece sleeve 208. Limiting rods 306 are symmetrically connected to the upper and lower sides of the connecting cylinder 207. The limiting rods 306 are slidably snapped onto the mouthpiece sleeve 208. A knob 307 is connected to the rear side of the rotating cylinder 301. A spring 308 is connected to the lower and right sides of the knob 307. The spring 308 contacts and engages with the support rod 203. The included angle between the two springs 308 on each knob 307 is 90 degrees. The spring 308 is used to limit the rotation angle between the knob 307 and the rotating cylinder 301.

[0031] When performing breathing training, place the device on a table. Initially, the mouthpiece 208 is snapped onto the connecting tube 207 via a snap-fit ​​assembly. The height of the adjusting frame 201 and guide frame 202 can be adjusted according to height. Pulling the handle will move the adjusting frame 201 and guide frame 202 up and down, and the mouthpiece 208 will move accordingly. The damper will stabilize the adjusting frame 201 and guide frame 202. After adjusting the operating controller 104, turn on the power to the device. Then, adjust the regulating valve 102 according to the doctor's instructions to adjust the airflow resistance of the breathing trainer 101. Next, operate the electric valve 204 to open the upper flow port and close the lower flow port. Then, in a standing or sitting position, hold the mouthpiece 208 in your mouth with a deep and even depth. The exhalation method raises the float 107 in the connecting tube and maintains it for as long as possible. The same method is used during inhalation training. When exhaling into the mouthpiece 208, the air enters the breathing trainer 101 through the flow tube 206 and the telescopic tube 106. Each connecting tube of the breathing trainer 101 is equipped with a float 107. As air enters the connecting tube, the float 107 rises. When the float 107 contacts the switch 108 and squeezes the switch 108, the return spring 109 is compressed. The controller 104 then controls the corresponding indicator light 105 to illuminate, thus reminding the patient. When exhalation stops, the float 107 falls downwards due to gravity, causing the return spring 109 to rebound and reset, the switch 108 to reset, and the controller 104 to reset. Then, control the corresponding indicator light 105 to turn off. After exhaling, remove the mouthpiece cover 208 to inhale air. Repeat the above operation for exhalation training. After exhalation training, perform inhalation training by inhaling into the mouthpiece cover 208, causing the float 107 to rise, and hold it for as long as possible. Then remove the mouthpiece cover 208 to exhale, rest for a moment, and then continuously repeat the exhalation and inhalation training. The breathing trainer 101 can train the respiratory muscle groups through the principle of impedance. After the training is completed, operate the controller 104 to start the motor 205, causing the output shaft of the motor 205 to rotate 180 degrees and then automatically shut off. The output shaft of the motor 205 will drive the electric valve 204 and the flow pipe 206 to rotate, which in turn drives the connecting cylinder 207 and the support rod 203 to rotate. All components on part 7 will rotate, including the gear ring 502. When the gear ring 502 rotates to contact the rack frame 501, the rack frame 501 meshes with the gear ring 502, causing the gear ring 502 to rotate 90 degrees. The gear ring 502 then drives the knob 307, the spring 308, and the rotating drum 301 to rotate 90 degrees. Initially, the mouthpiece sleeve 208 is in a locked state, and the compression spring 303 is in a compressed state. The locking block 305 and the reference groove 304 are paired on the Y-axis and paired on the X-axis, respectively, with the locking block 305 and the reference groove 304 misaligned. After the rotating drum 301 rotates 90 degrees, the locking block 305 will align with the reference groove 304, and the locking block 305 will no longer be blocked by the rotating drum 301. At this time, the compression spring 303 resets, causing the sliding ring 302 to move forward.This pushes the mouthpiece sleeve 208 forward to disengage from the connecting cylinder 207 and the limiting rod 306, completing the disassembly of the mouthpiece sleeve 208. When driven by the motor 205, the lower connecting cylinder 207 rotates to the upper position. When the next patient uses this device, the sterilized mouthpiece sleeve 208 can be installed on the upper connecting cylinder 207. During operation, the mouthpiece sleeve 208 is aligned with the limiting rod 306 and placed on the connecting cylinder 207. At this time, the locking block 305 on the mouthpiece sleeve 208 is aligned with the reference groove 304 on the connecting cylinder 207. When the mouthpiece sleeve 208 is installed on the connecting cylinder 207, the mouthpiece sleeve 208 will contact the sliding ring 302, thereby squeezing the sliding ring 302 to move backward. When the device moves, the return spring 109 is compressed. At this point, rotating the knob 307 90 degrees causes the spring 308, connecting cylinder 207, and gear ring 502 to rotate. The reference groove 304 on the connecting cylinder 207 then misaligns with the locking block 305. The spring 308 is then held in place by the support rod 203, ensuring that the knob 307 can only rotate 90 degrees at a time. Since the reference groove 304 is not aligned with the locking block 305, the mouthpiece sleeve 208 can be released and secured. This achieves automatic disassembly of the mouthpiece sleeve 208. Both the upper and lower connecting cylinders 207 can be used to install the mouthpiece sleeve 208, allowing for alternating use and providing convenience for patients. After use, simply operate the controller 104 to turn off the power to the device.

[0032] like Figure 7 As shown, the training device also includes a fixed block 401, a pushing block 402, a connecting frame 403, and a squeezing block 404. The fixed block 401 is connected to the upper side of the adjusting frame 201, and the pushing block 402 is welded to the bottom of the motor 205. The connecting frame 403 is connected to both flow pipes 206, and the squeezing block 404 is slidably connected to both connecting frames 403. The squeezing block 404 contacts the flow pipe 206, and the part of the flow pipe 206 that contacts the squeezing block 404 is a flexible tube. The pushing block 402 contacts and cooperates with the squeezing block 404. The outer walls of the pushing block 402 and the squeezing block 404 are both arc-shaped. The pushing block 402 pushes the squeezing block 404 to squeeze the flexible tube part of the flow pipe 206, which can prevent gas from flowing in the flow pipe 206.

[0033] Initially, the push block 402 presses against the lower compression block 404. Through the cooperation of the fixing block 401 and the lower compression block 404, the flexible portion of the lower flow tube 206 is compressed, and airflow ceases. When using this device for breathing training, the electric valve 204 can be opened directly without controlling the opening and closing of the upper and lower flow ports within the electric valve 204. When changing the mouthpiece sleeve 208, the electric valve 204 and flow tube 206 rotate, and the connecting bracket 403 and compression block 404 rotate accordingly. The lower compression block 404 disengages from the push block 402, and the compression block 404 is no longer compressed by the push block 402, allowing airflow to resume. The flexible part of 206 will rebound back to its initial state under its own elastic force, thereby pushing the corresponding squeezing block 404 to move and reset. After the upper flow tube 206 rotates 180 degrees, the squeezing block 404 on the upper flow tube 206 will contact the pushing block 402. The pushing block 402 pushes the squeezing block 404 to move backward. The flow tube 206 is held in place by the fixing block 401, while the squeezing block 404 squeezes the flexible part of the flow tube 206, closing the internal channel of the flow tube 206 and stopping the airflow. During breathing training, the gas will not enter the lower flow tube 206, thus eliminating the trouble of manually adjusting the electric valve 204.

[0034] like Figure 1 As shown, the training device also includes a guide plate 601 and a collection frame 602. The guide plate 601 is connected to the middle of the support frame 103. The collection frame 602 is placed on the bottom plate 1 at the left side of the guide plate 601. The disassembled mouthpiece cover 208 will fall onto the guide plate 601 and slide down into the collection frame 602, which facilitates the uniform disinfection of the mouthpiece cover 208.
