Description

Technical Field

[0001] This utility model relates to the field of medical equipment auxiliary device technology, specifically to a lung rehabilitation training device. Background Technology

[0002] Pulmonary rehabilitation is a multidisciplinary, comprehensive intervention approach for patients with symptomatic chronic respiratory diseases and declining daily living abilities. The scope of pulmonary rehabilitation is expanding beyond patients with lung diseases. Breathing training is a method to ensure airway patency, improve respiratory muscle function, promote sputum expectoration and drainage, and enhance gas exchange efficiency.

[0003] In practice, after a patient completes surgery, in order to assist in the recovery of lung function, in addition to medication, physical therapy is often required. Currently, a common method is to increase expiratory resistance by blowing up balloons to improve respiratory muscle function. However, when exercising by blowing up balloons, after the balloon inflates, the mouth needs to be separated from the balloon opening to release all the air before the next lung breathing exercise. This significantly wastes time in lung respiratory rehabilitation training. Furthermore, during balloon blowing exercises, patients can only roughly estimate the change in pressure with each breath based on the degree of balloon inflation, and cannot directly perceive the extent of pressure change with each breath. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lung rehabilitation training device to solve the problem mentioned in the background art that when performing lung training by blowing up a balloon, the mouth must be kept away from the balloon opening to wait for the balloon to expel air, which wastes training time.

[0005] To solve the above-mentioned technical problems, the basic solution adopted by this utility model is: a lung rehabilitation training device, including a device body, one end of the device body is provided with an air blowing channel, the other end of the device body is provided with a cavity 1 communicating with the air blowing channel, and the device body is provided with an air outlet 1 communicating with the cavity 1 and the external space of the device body.

[0006] An elastic membrane is fixedly connected to the device body and seals the air inlet.

[0007] A one-way mechanism includes a sliding column sealed and slidably connected within the air blowing channel, an air intake bypass disposed within the device body, an elastic element disposed within the air blowing channel between the sliding column and the cavity, and an exhaust port connecting the inner cavity of the air blowing channel between the sliding column and the cavity to the external space of the device body. One end of the air intake bypass is connected to the cavity, and the other end of the air intake bypass is connected to the air blowing channel. Under the elastic force of the elastic element, the sliding column is positioned to block the air intake bypass and allow the cavity to communicate with the external space of the device body through the exhaust port.

[0008] Furthermore, the air inlet end of the air blowing channel is detachably connected to an air nozzle.

[0009] Furthermore, a retaining ring is provided on the inner wall of the air inlet end of the air blowing channel. When the sliding column contacts the retaining ring under the elastic force of the elastic element, the sliding column blocks the air intake bypass and allows the cavity to communicate with the external space of the device body through the exhaust hole.

[0010] Furthermore, a retaining ring two is provided on the inner wall of the air blowing channel near the cavity one, and the elastic element one is a spring one, one end of the spring one is fixedly connected to the retaining ring two, and the other end of the spring one is fixedly connected to the sliding column.

[0011] Furthermore, it also includes a pressure display mechanism disposed on the device body for reflecting the gas pressure in the cavity during blowing.

[0012] Furthermore, the pressure display mechanism includes a transparent cylinder arranged radially along the air blowing channel, a slider that is slidably and sealingly connected to the inner wall of the transparent cylinder, and an elastic element II disposed within the transparent cylinder. The outer wall of the transparent cylinder is engraved with scale lines. One end of the transparent cylinder is an open end that is sealed and connected to the cavity, and the other end of the transparent cylinder is a closed end. The closed end of the transparent cylinder is provided with a vent hole that connects the inner cavity of the transparent cylinder with the space of the outer wall of the transparent cylinder. The elastic element II is disposed near the closed end of the transparent cylinder and pushes the slider toward the cavity.

[0013] Furthermore, the device body is provided with an air port two that connects the cavity one to the external space of the device body, and the open end of the transparent cylinder is fixedly and sealed to the air port two.

[0014] Furthermore, the second elastic element is a second spring arranged radially along the transparent cylinder. One end of the second spring is fixedly connected to the inner wall of the closed end of the transparent cylinder, and the other end of the second spring is fixedly connected to the slider.

[0015] Furthermore, the device body is provided with a flow-blocking mechanism, which includes a rectangular slide groove arranged radially within the device body along the air blowing channel, a slide plate arranged within the rectangular slide groove, and a threaded rod for adjusting the slide plate to slide within the rectangular slide groove. The rectangular slide groove is intersecting and communicating with the air intake bypass. The slide plate is slidably connected to the rectangular slide groove in a sealed manner. The threaded rod is arranged radially along the air blowing channel. The inner end of the threaded rod is rotatably connected to the slide plate. The outer end of the threaded rod extends out of the device body. The device body is provided with an internal thread that mates with the threaded rod.

[0016] When the threaded rod is rotated to drive the slide plate to slide in the rectangular groove, the slide plate changes the size of the intake bypass channel, thereby adjusting the resistance of the blowing airflow.

[0017] Furthermore, the elastic membrane is an elastic balloon that is sealed and connected to the air vent.

[0018] Compared with existing technologies, the pulmonary rehabilitation training device of this solution has at least the following beneficial effects:

[0019] 1. During use, the user does not need to remove their mouth from the device. The air exhaled into the device is automatically expelled through the exhaust port when the user stops exhaling and inhales through the nose, simplifying the exercise steps and making full use of exercise time to improve the exercise effect.

[0020] 2. During the blowing exercise, this device allows for a direct comparison of the blowing pressure each time, making it convenient for users to adjust the blowing force.

[0021] 3. During use, this device can adjust the air intake bypass area by rotating the threaded rod to drive the slide plate, thereby adjusting the blowing resistance. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0037] A lung rehabilitation training device according to this embodiment includes a device body 10, an elastic membrane disposed on the device body 10, a one-way mechanism that allows only one-way flow of blowing air within the device body 10, a pressure display mechanism for observing the blowing pressure within the device body 10, and a flow-assisting mechanism for adjusting the resistance of the blowing air.

[0038] like Figures 1-5As shown, the device body 10 is a horizontally arranged cylinder. The first end of the device body 10 is the air inlet section of the air blowing channel 101. The air inlet section is provided with an air blowing channel 101 extending into the device body 10. The air inlet section of the air blowing channel 101 is detachably connected to the air nozzle 40. Specifically, the air nozzle 40 can be connected to the device body 10 by a threaded connection or a plug-in connection, which facilitates the replacement and disassembly and cleaning of the air nozzle 40 when used by different patients. The second end of the device body 10 is provided with a cavity 102 communicating with the air blowing channel 101. The device body 10 is provided with an air outlet 1021 communicating with the external space of the device body 10. The air outlet 1021 is located at the second end of the device body 10. The end of the device body 10 near the air outlet 1021 is provided radially with an air outlet 103 communicating with the external space of the device body 10.

[0039] The elastic membrane is an elastic balloon 20 that is sleeved on the second end of the device body 10 to close the air port 1021. The elastic balloon 20 is tied to the device body 10 with a strap, and a new elastic balloon 20 can be replaced after the strap is loosened.

[0040] The one-way mechanism includes a sliding column 31 that is sealed and slidably connected in the air blowing channel 101, an air intake bypass 32 disposed in the device body 10, a spring 33 disposed in the air blowing channel 101 between the sliding column 31 and the cavity 102, and an exhaust port 34 that connects the inner cavity of the air blowing channel 101 between the sliding column 31 and the cavity 102 with the external space of the device body 10. One end of the air intake bypass 32 is connected to the cavity 102, and the other end of the air intake bypass 32 extends toward the air nozzle 40 and is connected to the air blowing channel 101. A retaining ring 35 is provided on the inner wall of the air inlet end of the air blowing channel 101, and a retaining ring 36 is provided on the inner wall of the air blowing channel 101 near the cavity 102. Both retaining rings 35 and 36 are annular. The outer walls of both retaining rings 35 and 36 are fixedly connected to the inner wall of the air blowing channel 101. One end of the spring 33 is fixedly connected to the retaining ring 36, and the other end of the spring 33 is fixedly connected to the sliding column 31. Figure 1As shown, under the elastic force of spring 33, the end of the slide column 31 near the air nozzle 40 contacts the single ring. At this time, the slide column 31 blocks the air intake bypass 32 and allows the cavity 102 to communicate with the external space of the device body 10 through the exhaust port 34. When the slide column 31 contacts the retaining ring 35, the spring 33 is still in a compressed state to prevent the slide column 31 from sliding back and forth in the air blowing channel 101. The elastic force of the spring 33 is set to be small, only used to keep the slide column 31 in contact with the retaining ring 35 and push the slide column 31 to reset when the air blowing stops. It will not produce a large resistance effect on the air blowing airflow.

[0041] The pressure display mechanism includes a transparent cylinder 51 coaxially arranged with the second air port 103, a slider 52 slidably connected to the inner wall of the transparent cylinder 51, and a second spring 53 disposed inside the transparent cylinder 51. One end of the transparent cylinder 51 near the second air port 103 is an open end, which is sealed and fixedly connected to the second air port 103. The other end of the transparent cylinder 51 is a closed end, which is provided with a vent hole 54 that connects the inner cavity of the transparent cylinder 51 with the outer wall space of the transparent cylinder 51. The second spring 53 is arranged along the axis of the transparent cylinder 51. One end of the second spring 53 is fixedly connected to the inner wall of the closed end of the transparent cylinder 51, and the other end of the second spring 53 is fixedly connected to the slider 52. Under the elastic force of the second spring 53, the slider 52 is located at the end of the transparent cylinder 51 near the second air port 103. The outer wall of the transparent cylinder 51 is engraved with scale lines.

[0042] like Figure 1 , Figure 2As shown, the flow obstruction mechanism includes a rectangular slide groove 61 radially disposed within the device body 10 along the air blowing channel 101, a sliding plate 62 disposed within the rectangular slide groove 61, and a threaded rod 63 for adjusting the sliding plate 62 within the rectangular slide groove 61. The rectangular slide groove 61 is intersecting and communicating with the air intake bypass 32. The sliding plate 62 is slidably connected to the rectangular slide groove 61. The threaded rod 63 is radially disposed along the air blowing channel 101. The inner end of the threaded rod 63 is rotatably connected to the sliding plate 62, and the outer end of the threaded rod 63 extends outside the device body 10. The device body 10 is provided with an internal thread that mates with the threaded rod 63. When the threaded rod 63 is rotated to drive the sliding plate 62 to slide within the rectangular slide groove 61, the sliding plate 62 changes the channel size of the air intake bypass 32, thereby adjusting the resistance of the blowing airflow. To facilitate the installation of the slider 52 and the threaded rod 63, the device body 10 also includes a movable block 64. Specifically, an opening communicating with the rectangular slide groove 61 is provided in the device body 10 corresponding to the rectangular slide groove 61. A movable block 64 is screwed to the opening to block it. The movable block 64 is provided with a threaded through hole that mates with the threaded rod 63. A cap that is detachably connected to the outer end of the threaded rod 63 is provided to facilitate the screwing of the threaded rod 63.

[0043] In this device, when no air is being blown in, spring 33 forces slide 31 to contact retaining ring 35. At this time, slide 31 blocks the air intake bypass 32, and exhaust port 34 connects to cavity 102 via air blowing channel 101. Gas in cavity 102 can be discharged to the outside of the device body 10 through exhaust port 34. Under the elastic force of spring 53, slider 52 is located in the inner cavity of transparent cylinder 51 near cavity 102. When breathing training and lung rehabilitation are needed, hold the device body 10 so that the closed end of transparent cylinder 51 is in an upright position facing upwards to facilitate observation of the scale lines on transparent cylinder 51. When air is blown into air blowing channel 101 through nozzle 40, under the compression of the blowing air pressure, slide 31 slides towards cavity 102, combined with... Figure 4 , Figure 5 As shown, when the slide column 31 slides to connect the air intake bypass 32 with the air blowing channel 101 near the nozzle 40, the slide column 31 completely blocks the exhaust port 34. The blowing gas flows through the air intake bypass 32 into the cavity 102, causing the elastic balloon 20 to expand and forcing the slider 52 to slide upward. The greater the blowing pressure, the higher the slider 52 slides upward. The pressure change during each blowing can be compared through the scale lines on the transparent cylinder 51. When the blowing ends, the blowing pressure drops sharply, and the spring pushes the slide column 31 to slide towards the nozzle 40 until it contacts the retaining ring 35. At this time, the slide column 31 blocks the air intake bypass 32 and opens the exhaust port 34. The elastic membrane contracts and the slider 52 descends, venting the gas in the cavity 102 to the outside of the device body 10 through the exhaust port 34. Then the user can blow again.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
