Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a sputum removal device. Background Art

[0002] Difficulty in expectoration is a common symptom of the respiratory system. Clinical patients often have difficulty in expectoration due to excessive and viscous sputum. Poor sputum discharge often leads to respiratory dysfunction and lung infection. Timely removal of sputum is the primary nursing measure to ensure that the patient's respiratory tract is unobstructed and is also an effective method for preventing lung infection. It can be seen that effectively removing sputum from the patient's respiratory tract is very important. In order to help patients expectorate, the prior art CN 216366534 U discloses a respiratory training expectoration device. This solution uses the airflow during the user's breathing to push the seesaw to flip and intermittently open or close the airway to form an oscillating airflow. In this solution, when the seesaw closes the airway, the respiratory airflow is blocked and exhalation / inhalation is blocked. Then the seesaw suddenly opens quickly again, forming an intermittent on / off rapid airflow under the user's exhalation / inhalation action. That is, this air oscillation is caused by the intermittent on / off of gas during the user's breathing. The pressure difference formed when the airflow is on / off easily causes the user to have difficulty breathing and choke instead of cough effectively, causing discomfort to the user. Summary of the Invention

[0003] The purpose of the present invention is to provide a sputum removal device to effectively solve the problem in the prior art that the air oscillation formed by intermittently interrupting / opening the user's respiratory airflow easily causes the user to choke and cough, thereby reducing the sputum removal efficiency.

[0004] To achieve the above object, the basic scheme of the present invention is as follows:

[0005] A sputum removal device comprises a shell and an oscillation mechanism arranged in the inner cavity of the shell, the oscillation mechanism comprises a slide fixedly connected to the inner wall of the shell, a slide column arranged in the slide, a driving unit for driving the slide column to slide, a control unit for controlling the operation of the driving unit and a vibrating member arranged at one end of the slide and vibrating synchronously with the slide column, the shell and the slide are both cylindrical bodies with openings at both ends, the slide is coaxially arranged with the shell, the outer diameter of the slide is smaller than the inner diameter of the shell, the slide is fixedly connected to the shell by a connecting rod, the slide column is slidably connected to the inner wall of the slide, and the control unit controls the driving unit to drive the slide column to slide back and forth according to the airflow rate during the user's breathing / inhalation to force the vibrating member to vibrate and thereby generate air oscillations in the user's respiratory tract.

[0006] The principle and beneficial effects of the basic solution of the present invention are:

[0007] The user holds the first end of the shell with his mouth and breathes, and the control unit controls the vibration frequency of the vibrator according to the user's breathing / exhaling rate, and further controls the air oscillation frequency in the user's respiratory tract. The air oscillation acts in the user's respiratory tract, which can promote the swing amplitude of the respiratory cilia, loosen sputum and promote sputum discharge. Under this solution, the user can control the vibration frequency of the vibrator by independently adjusting the breathing / exhaling rate based on personal experience during use, including the smoothness, comfort, and sputum loosening rate of the vibrator when breathing at different vibration frequencies, thereby achieving optimal use comfort and optimal sputum discharge effect.

[0008] Furthermore, the sliding column is an iron column, and the driving unit includes an annular electromagnet arranged near the inner cavity of the first end of the slide cylinder, a vibration spring arranged between the annular electromagnet and the sliding column, and a power supply arranged on the outer shell. The annular electromagnet is electrically connected to the power supply, and a power switch is provided on the outer shell. One end of the vibration spring is fixedly connected to the sliding column, and the other end of the vibration spring is fixedly connected to the annular electromagnet.

[0009] Furthermore, the vibrating member is a vibrating membrane provided at the first end of the slide cylinder, and the vibrating membrane is fixedly connected to the inner wall of the slide cylinder along its circumference to seal the first end of the slide cylinder.

[0010] Furthermore, the control unit includes a first control unit for controlling the operation of the driving unit according to an inhalation rate of the user and a second control unit for controlling the operation of the driving unit according to an exhalation rate of the user.

[0011] Furthermore, the first control unit includes a first impeller mounted outside the slide and connected to the slide for unidirectional rotation, and a first contact switch arranged on the inner wall of the outer shell, the first impeller includes a plurality of spiral blades evenly spaced apart, the first contact switch is connected in series to the circuit electrically connecting the power supply and the annular electromagnet, and when the first impeller rotates so that the spiral blades on the first impeller pass through the position of the first contact switch, the spiral blades on the first impeller squeeze and trigger the first contact switch.

[0012] When the user inhales, air flows through the annular area between the slide and the housing, impacting the first impeller and causing it to rotate. When the spiral blades on the first impeller rotate past the location of the first spring, the ends of the spiral blades press against the spring, causing the first moving contact to contact the first static contact. The annular electromagnet is energized, attracting the slide to slide closer to the annular magnet. After the spiral blades of the first impeller rotate past the first spring, the spring rebounds, separating the first static contact from the first moving contact. The annular electromagnet loses power, and the vibration spring forces the slide to slide away from the annular magnet. As the user inhales, the rotation of the first impeller causes the spiral blades on the first impeller to continuously squeeze and release the first spring, causing the slide to repeatedly slide within the slide, thereby vibrating the diaphragm. This vibration generates air oscillations in the user's respiratory tract, promoting the discharge of phlegm.

[0013] The cam is secured to the outer wall of the sliding member with a secure connection to the first end of the sliding member and secured to the second end of the sliding member with a secure connection to the first end of the sliding member.

[0014] Furthermore, a first mounting groove is recessed on the inner wall of the shell, and the first contact switch is arranged in the first mounting groove. The first contact switch includes a first spring piece, a first static contact electrically connected to one pole of the power supply, and a first moving contact electrically connected to the other pole of the power supply. The first static contact is fixed in the first mounting groove, one end of the first spring piece is fixed in the first mounting groove, and the other end of the first spring piece is a free end. The free end of the first spring piece extends out of the first mounting groove at an angle along the rotation direction of the first impeller, and the first moving contact is arranged at the free end of the first spring piece.

[0015] When the user inhales, the airflow acts on the first impeller to make the first slip ring slide a certain distance toward the limit ring and make the first impeller rotate, and the first return spring is compressed. At this time, the radial projection of the first impeller and the first elastic piece in the slide cylinder has an overlapping area. When the first impeller rotates, the end of the spiral blade on the first impeller can squeeze the first elastic piece. When the user stops inhaling, the first return spring forces the first slip ring to slide away from the limit ring, and the first impeller and the first elastic piece are staggered to prevent the situation where the end of a spiral blade on the first impeller just stops at the position pressing the first elastic piece when the first impeller stops, so that the annular electromagnet is always in the state of energizing the adsorption column slide.

[0016] Furthermore, the second control unit includes a second impeller mounted outside the slide and connected to the slide for unidirectional rotation, and a second contact switch arranged on the inner wall of the outer shell, the second impeller includes a plurality of spiral blades evenly spaced apart, the second contact switch is connected in parallel with the first contact switch and then in series with the circuit electrically connecting the power supply and the annular electromagnet, when the second impeller rotates so that the spiral blades on the second impeller pass through the position of the second contact switch, the spiral blades on the second impeller squeeze and trigger the second contact switch.

[0017] The cam is secured to the outer wall of the sliding member with a spring which is secured to the outer wall of the sliding member with a spring which is secured to the outer wall of the sliding member with a spring which is secured to the inner wall of the sliding member with a spring which is secured to the outer wall of the sliding member with a spring which is secured to the outer wall of the sliding member with a spring which is secured to the outer wall of the sliding member with a spring which is secured to the outer wall of the sliding member with a spring

[0018] Furthermore, a second mounting groove is recessed on the inner wall of the shell, and the second contact switch is arranged in the second mounting groove. The second contact switch includes a second static contact electrically connected to one pole of the power supply, a second moving contact electrically connected to the other pole of the power supply, and a second elastic piece. The second static contact is fixed in the second mounting groove, one end of the second elastic piece is fixed in the second mounting groove, and the other end of the second elastic piece is a free end. The free end of the second elastic piece extends out of the second mounting groove at an angle along the rotation direction of the second impeller, and the second moving contact is arranged at the free end of the second elastic piece.

[0019] When the user inhales, the first impeller rotates clockwise under the impact of the inhaled airflow, and the second impeller cannot rotate. When exhaling, the first impeller cannot rotate, and the exhaled airflow impacts the second impeller, causing the second slip ring to approach the limit ring and rotate the second impeller, and the second return spring is compressed. At this time, the second impeller and the second elastic piece have an overlapping area of ​​projection in the radial direction of the slide cylinder. When the second impeller rotates, the end of the spiral blade on the second impeller can squeeze the second elastic piece. When the user stops exhaling, the second return spring forces the second slip ring to slide away from the limit ring, and the second impeller and the second elastic piece are staggered to prevent the situation where the end of a spiral blade on the second impeller just stops at the position that presses the second elastic piece when the second impeller stops, so that the annular electromagnet is always in the state of energizing the adsorption column slide.

[0020] Compared with the prior art method of forming an oscillating airflow by intermittently interrupting and connecting the user's breathing airflow, the present invention has at least the following beneficial effects:

[0021] 1. When the present invention is in use, the airflow during the user's breathing is only used to drive the impeller to rotate, and is not used to push a sealing member to open or close the channel for the breathing airflow. Therefore, the user's breathing airflow will not be intermittently switched on / off, and the user will not feel shortness of breath, nor will the user experience choking or other discomfort caused by the intermittent switching on / off of the breathing airflow.

[0022] 2. In this solution, users can control the vibration frequency of the vibrator by adjusting their breathing rate based on their personal experience of the smoothness, comfort, and sputum loosening rate of the vibrator at different vibration frequencies, thereby achieving optimal comfort and expectoration effect.

When the slide 201 slides back and forth in the inner cavity of the slide cylinder 20 under the action of the electromagnet and the vibration spring 204, the vibration membrane 205 vibrates synchronously with the slide 201, thereby generating air oscillations in the user's respiratory tract. The vibration membrane 205 closes the first end of the slide cylinder 20 and can also prevent liquid from entering the interior of the slide cylinder 20 from the user's mouth.

[0037] The control unit includes a first control unit for controlling the operation of the driving unit according to an inhalation rate of a user and a second control unit for controlling the operation of the driving unit according to an exhalation rate of the user.

[0038] Combine Figure 1 、 Figure 2 、 Figure 4 As shown, the first control unit specifically includes a first slide rail 302 arranged on the outer wall of the slide 20 in a direction parallel to the axis of the slide 20, a first slip ring 303 sleeved on the outer wall of the slide 20 and slidably connected to the outer wall of the slide 20, a first impeller 301 sleeved outside the first slip ring 303 and unidirectionally connected to the first slip ring 303, a limit ring 309 fixedly connected to the outer wall of the slide 20, a first contact switch arranged on the inner wall of the housing 10 and a first return spring 304 arranged between the limit ring 309 and the first slip ring 303. The first sliding ring 303 is provided with a sliding groove that slides with the first sliding rail 302, and the limiting ring 309 is provided on the side of the first sliding ring 303 close to the first end of the slide cylinder 20. The limiting ring 309 is provided with a sliding groove that cooperates with the first sliding rail 302 so that the limiting ring 309 can slide over the first sliding rail 302 during actual installation, and then the limiting ring 309 can be fixedly connected to the slide cylinder 20 by screws. One end of the first return spring 304 is fixedly connected to the limiting ring 309, and the other end of the first return spring 304 is fixedly connected to the limiting ring 309. The first end is fixedly connected to the first slip ring 303, the first impeller 301 includes a plurality of spiral blades 3011 evenly spaced, and the first impeller 301 and the first slip ring 303 are connected in one direction by a one-way bearing so that the first impeller 301 can only rotate clockwise. The first contact switch is arranged on the inner wall of the housing 10 between the first impeller 301 and the limit ring 309. The first contact switch is connected in series with the power switch 104. Specifically, a first mounting groove 305 is recessed on the inner wall of the housing 10. The first contact switch is arranged on the inner wall of the housing 10. In the first mounting slot 305, the first contact switch includes a first spring 308, a first static contact 306 electrically connected to one pole of the rechargeable battery through the power switch 104, and a first moving contact 307 electrically connected to the other pole of the rechargeable battery. The first static contact 306 is fixed in the first mounting slot 305. One end of the first spring 308 is fixed in the first mounting slot 305, and the other end of the first spring 308 is a free end. The free end of the first spring 308 extends out of the first mounting slot 305 in an inclined manner along the rotation direction of the first impeller 301. 05. The first moving contact 307 is arranged at the free end of the first elastic piece 308. In the original state when the sputum discharge device is not in use, under the elastic force of the first return spring 304, the first slip ring 303 is located at a position where the first impeller 301 and the radial projection of the first elastic piece 308 in the slide cylinder 20 are staggered, specifically, the end of the spiral blade 3011 on the first impeller 301 is staggered with the first elastic piece 308 so that the end of the spiral blade 3011 on the first impeller 301 cannot contact the first elastic piece 308 when the first impeller 301 rotates.

[0039] Combine Figure 1 、 Figure 2 、 Figure 5 As shown, the second control unit specifically includes a second slide rail 402 arranged on the outer wall of the slide cylinder 20 along a direction parallel to the axis of the slide cylinder 20 and arranged on the outer wall of the slide cylinder 20 corresponding to the second slide rail 402, a second slip ring 403 slidingly connected to the outer wall of the slide cylinder 20, a second impeller 401 sleeved outside the second slip ring 403 and unidirectionally connected to the second slip ring 403, a second contact switch arranged on the inner wall of the housing 10, and a second return spring 404 arranged between the limit ring 309 and the second slip ring 403. The second slip ring 403 is provided with a sliding groove that slides with the second slide rail 402. The second impeller 401 and the second slip ring 403 are connected in one direction by a one-way bearing so that the second impeller 401 can only rotate counterclockwise. The second impeller 401 includes a plurality of spiral blades 4011 evenly spaced. One end of the second return spring 404 is fixedly connected to the limit ring 309, and the other end of the second return spring 404 is fixedly connected to the second slip ring 403. The second contact switch is provided on the inner wall of the housing 10 between the second impeller 401 and the limit ring 309. The second contact switch is connected to the first contact The point switch is connected in parallel with the power switch 104 in series. Specifically, a second mounting groove 405 is recessed on the inner wall of the housing 10. The second contact switch is arranged in the second mounting groove 405. The second contact switch includes a second elastic piece 408, a second static contact 406 electrically connected to one pole of the rechargeable battery through the power switch 104, and a second movable contact 407 electrically connected to the other pole of the rechargeable battery. The second static contact 406 is fixed in the second mounting groove 405. One end of the second elastic piece 408 is fixed in the second mounting groove 405, and the other end of the second elastic piece 408 is a free end. The second elastic piece 408 is free. The second end extends out of the second mounting slot 405 obliquely along the rotation direction of the second impeller 401, and the second moving contact 407 is arranged at the free end of the second elastic piece 408. When the sputum discharge device is in the original state when it is not in use, under the elastic force of the second reset spring 404, the second slip ring 403 is located at a position that staggers the radial projection of the second impeller 401 and the second contact switch in the slide cylinder 20, specifically, the end of the spiral blade 4011 on the second impeller 401 is staggered with the second elastic piece 408 so that the end of the spiral blade 4011 on the second impeller 401 cannot contact the second elastic piece 408 when the second impeller 401 rotates.

[0040] When the present invention is in use, the power switch 104 is manually closed, and the air nozzle 101 is aimed at the mouth for breathing. When the user inhales, the air flow flows from the annular area between the slide cylinder 20 and the housing 10 to the air nozzle 101. Under the impact of the inhaled air flow, the first impeller 301 rotates clockwise, and the second impeller 401 cannot rotate. When inhaling, the air flow acts on the first impeller 301 to make the first slip ring 303 slide a certain distance toward the limit ring 309 and rotate the first impeller 301. The first return spring 304 is compressed. At this time, the projections of the first impeller 301 and the first elastic piece 308 in the radial direction of the slide cylinder 20 overlap. When the first impeller 301 rotates, the end of the spiral blade 3011 on the first impeller 301 can squeeze the first spring 308, causing the first static contact 306 of the first contact switch to contact the first movable contact 307, thereby energizing the annular electromagnet 203 and attracting the slide 201 to slide closer to the annular magnet. After the spiral blade 3011 of the first impeller 301 rotates over the first spring 308, the first spring 308 rebounds, separating the first static contact 306 from the first movable contact 307. The annular electromagnet 203 loses power, and the vibration spring 204 forces the slide 201 to slide away from the annular magnet. As inhalation proceeds, the first impeller 301 rotates, causing the spiral blade 3011 on the first impeller 301 to intermittently squeeze and release the first spring 308, causing the slide 201 to repeatedly slide within the slide cylinder 20, thereby causing the vibrating membrane 205 to vibrate. The vibration of the vibrating membrane 205 generates air oscillations in the user's respiratory tract, promoting the loosening and discharge of sputum in the respiratory tract.

[0041] When the user stops inhaling, the first return spring 304 forces the first slide ring 303 to slide away from the limit ring 309, and the first impeller 301 is staggered with the first elastic piece 308 to prevent the end of a spiral blade 3011 on the first impeller 301 from stopping at the position pressing the first elastic piece 308 when the first impeller 301 stops, so that the annular electromagnet 203 is always in a state of being energized to adsorb the column slide 201.

[0042] When exhaling, the exhaled airflow impacts the second impeller 401, causing the second slip ring 403 to approach the limit ring 309 and causing the second impeller 401 to rotate counterclockwise, and the second return spring 404 is compressed. At this time, the radial projection of the second impeller 401 and the second elastic piece 408 in the slide cylinder 20 has an overlapping area. When the second impeller 401 rotates, the end of the spiral blade 4011 on the second impeller 401 can squeeze the second elastic piece 408, so that the second static contact 406 of the second contact switch contacts the second moving contact 407, and the annular electromagnet 203 is energized to attract the slide column 201 to slide close to the annular magnet. After the spiral blade 4011 of the second impeller 401 rotates over the second elastic piece 408, the second elastic piece 408 rebounds to separate the second static contact 406 from the second moving contact 407, and the annular electromagnet 203 loses power. The vibration spring 204 forces the slide column 201 to slide away from the annular magnet. As the exhalation proceeds, the second impeller 401 rotates so that the spiral blade 4011 on the second impeller 401 intermittently squeezes and releases the second elastic piece 408, causing the slide column 201 to slide repeatedly in the slide cylinder 20, thereby causing the vibration membrane 205 to vibrate. When the user stops exhaling, the second return spring 404 forces the second slide ring 403 to slide away from the limit ring 309, and the second impeller 401 is staggered with the second elastic piece 408 to prevent the end of a spiral blade 4011 on the second impeller 401 from stopping at the position pressing the second elastic piece 408 when the second impeller 401 stops moving, so that the annular electromagnet 203 is always in a state of being energized to adsorb the column slide column 201.

[0043] The above are only embodiments of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
