Description

Technical Field

[0001] This invention relates to the field of sputum expectoration technology, specifically to a sputum expectoration device. Background Technology

[0002] Many critically ill patients experience impaired pulmonary ventilation, and some may have lung infections. This obstruction of ventilation, coupled with weakness and an inability to cough up sputum, leads to a buildup of secretions in the lungs, especially during recovery and periods of restricted activity. Assisting post-operative or weakened patients to enhance their expectoration abilities and improve stagnant pulmonary blood circulation is crucial. This is where expectoration machines come in, helping to promptly remove sputum from the patient's body. For example, after a tracheotomy, the limited cough mechanism can lead to secretion buildup and difficulty breathing; therefore, clearing secretions from the trachea, maintaining a clear airway, and preventing suffocation become particularly important. Sputum expectorants are a commonly used clinical device to assist patients in expectorating sputum. Most current sputum expectorants utilize vibration to cause the cilia deep in the airway to vibrate, loosening the sputum and other secretions stuck in the airway and detaching them from the airway surface. There are many ways to generate vibration, but current sputum expectorants cannot effectively adjust the frequency and amplitude of the vibration. Summary of the Invention

[0003] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is that the current sputum suction device cannot effectively adjust the frequency and amplitude of vibration.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a sputum suction device, comprising: The casing has an air inlet and an air outlet. A vibration mechanism is located between the air inlet and the air outlet. The vibration mechanism includes a base, a rotating shaft, a spring, and fan blades. The base is fixedly installed inside the housing and has mounting holes. The base also has multiple inclined openings communicating with the mounting holes, arranged in a circular array around the mounting holes. One end of the rotating shaft is inserted into the mounting hole, and the other end passes through the housing and extends outside the housing. The spring provides a thrust to the rotating shaft towards the mounting holes. The multiple fan blades are fixedly installed on the rotating shaft. An inclined member, mounted on a rotating shaft, is located within an inclined opening, and the inclined angle of the inclined member is adjustable; and An air blowing pipe is installed on the housing and is fitted onto the rotating shaft; a connection port is provided on one side of the air blowing pipe, the connection port is located on the stroke of the rotating shaft, and the connection port is connected to the air inlet.

[0005] Preferably, the tilting component includes a tilting rod, a tilting sleeve, and a sliding seat; one end of the tilting rod is slidably inserted into one end of the tilting sleeve; the other end of the tilting rod is hinged to the sliding seat, the other end of the tilting sleeve is hinged to the rotating shaft, and the sliding seat is slidably installed inside the rotating shaft along the length direction of the rotating shaft.

[0006] Preferably, it also includes an adjustment mechanism, which can adjust the sliding distance of the sliding seat.

[0007] Preferably, the adjusting mechanism includes: a threaded sleeve, a threaded rod, and a driving component; the threaded sleeve is fixedly connected to the sliding seat, the threaded rod is rotatably connected to the rotating shaft, and the threaded rod is threadedly connected to the threaded sleeve; the driving component can drive the threaded rod to rotate.

[0008] Preferably, the rotating shaft includes a rotating section, a plugging section, and a sealing section; one end of the plugging section is fixedly connected to one end of the rotating section, and the plugging section is configured to mate with a mounting hole; one end of the sealing section is slidably plugged into the other end of the rotating section along the length of the rotating section; the adjusting mechanism is installed inside the rotating section; the sealing section is threadedly connected to the end of the threaded rod away from the threaded sleeve; and the internal thread of the sealing section is opposite in direction to that of the threaded sleeve; the sealing section extends into the air blowing pipe.

[0009] Preferably, the spring is sleeved on the sealing section, with one end of the spring abutting against the housing and the other end of the spring abutting against the rotating section.

[0010] Preferably, there are multiple tilting members, and each tilting member corresponds to a mounting hole.

[0011] Preferably, the connection port is connected to the air inlet via a connecting pipe.

[0012] Compared with the prior art, the present invention has at least the following advantages: 1. In this invention, the patient blows air through one end of the air inlet, causing the gas to enter the housing through the connection port and air inlet. The gas drives the fan blades to move, which in turn drives the rotating shaft to rotate. The rotating shaft drives the tilting member to move within the tilted opening. Under the action of the tilted surface within the tilted opening, the tilting member moves outward, thereby causing the rotating shaft to move towards the air inlet. This causes the end of the rotating shaft to partially block the connection port, thus reducing the cross-sectional area of ​​the connection port and increasing the resistance during the patient's blowing. Simultaneously, the movement of the rotating shaft compresses the spring. Then, the rotating shaft continues to move, causing the tilting member to enter the next tilted opening. At this point, the spring pushes the rotating shaft towards the side away from the air inlet. The movement increases the cross-sectional area of ​​the connection port, thus reducing the resistance when the patient blows air. This cycle repeats, causing the shell to vibrate. The exhaled air also vibrates as the resistance changes. This air vibration causes the cilia deep within the airway to vibrate, loosening sputum and other secretions adhering to the airway and detaching them from the airway surface. Once the sputum and other secretions have loosened and detached, the sputum expectoration device can be removed for coughing. Repeated operation has a good sputum expectoration effect. Furthermore, by adjusting the tilt angle of the tilting component, the distance of the reciprocating movement of the rotating shaft can be adjusted, thereby adjusting the maximum resistance during exhalation, and thus adjusting the frequency and amplitude of the vibration.

[0013] 2. In this invention, the driving component drives the threaded rod to rotate, and the threaded rod can adjust the length of the protruding sealing section; thereby, the size of the sealing section's blockage of the connection port can be adjusted; thus, the frequency and amplitude of vibration can be further adjusted.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] See Figures 1-5The present invention provides an embodiment of a sputum expectoration device, comprising: a housing 1, a vibration mechanism 2, an inclined member 3, and an air blowing pipe 4; the housing 1 has an air inlet 11 and an air outlet 12; the vibration mechanism 2 is located between the air inlet 11 and the air outlet 12; the vibration mechanism 2 includes: a base 21, a rotating shaft 22, a spring 23, and a fan blade 24; the base 21 is fixedly installed inside the housing 1, and the base 21 has a mounting hole 211, and the base 21 also has a plurality of inclined openings 212 communicating with the mounting hole 211, the plurality of inclined openings 212 being distributed in a circular array with the mounting hole 211 as the center; one end of the rotating shaft 22 is inserted into the mounting hole 211, and the other end of the rotating shaft 22 passes through the housing 1 and extends outside the housing 1; the spring 23 provides a thrust to the rotating shaft 22 toward the mounting hole 211; further, the spring 23 is sleeved on the blocking section 223. The spring 23 is mounted on the rotating shaft 22, with one end abutting against the housing 1 and the other end abutting against the rotating section 221. This applies a thrust toward the mounting hole 211 to the rotating shaft 22. Multiple fan blades 24 are fixedly mounted on the rotating shaft 22. An inclined member 3 is mounted on the rotating shaft 22, located inside the inclined opening 212, and the inclined angle of the inclined member 3 is adjustable. Furthermore, multiple inclined members 3 are provided, and each inclined member 3 corresponds one-to-one with the mounting hole 211. This improves the stability of the reciprocating movement of the rotating shaft 22. An air blowing pipe 4 is mounted on the housing 1 and fits onto the rotating shaft 22. A connection port 41 is provided on one side of the air blowing pipe 4, located on the stroke of the rotating shaft 22, and the connection port 41 is connected to the air inlet 11. Furthermore, the connection port 41 is connected to the air inlet 11 through a connecting pipe 6.

[0025] In practice, the patient blows air through one end of the air inlet pipe 4, causing the gas to enter the housing 1 through the connection port 41 and the air inlet 11. The gas pushes the fan blade 24 to move, which in turn drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the tilting member 3 to move within the tilting port 212. Under the action of the tilted surface within the tilting port 212, the tilting member 3 moves outward, causing the tilting member 3 to drive the rotating shaft 22 towards the air inlet pipe 4. This causes the end of the rotating shaft 22 to partially block the connection port 41, thereby reducing the cross-sectional area of ​​the connection port 41 and increasing the resistance when the patient blows air. Simultaneously, the movement of the rotating shaft 22 causes the spring 23 to compress. Then, the rotating shaft 22 continues to move, causing the tilting member 3 to enter the next tilting port 212. At this time, the spring 23... 3. Push the rotating shaft 22 to move away from the blowing pipe 4, so that the cross-sectional area of ​​the connection port 41 increases, thus reducing the resistance when the patient blows air. Repeat this cycle, so that the shell 1 vibrates, and the exhaled air will also vibrate when the resistance changes. The vibration of the air causes the cilia on the inner wall of the airway to vibrate, loosening the sputum and other secretions stuck in the airway and detaching them from the airway surface. After feeling the sputum and other secretions loosened and detached, the sputum expectoration device can be removed and coughing can be performed. Repeated operation has a good sputum expectoration effect. Furthermore, by adjusting the tilt angle of the tilting part 3, the distance of the reciprocating movement of the rotating shaft 22 can be adjusted, thus adjusting the magnitude of the maximum resistance during exhalation, and thus adjusting the frequency and amplitude of vibration.

[0026] See Figures 1-5 In other embodiments, the tilting member 3 includes a tilting rod 31, a tilting sleeve 32, and a sliding seat 33; one end of the tilting rod 31 is slidably inserted into one end of the tilting sleeve 32; the other end of the tilting rod 31 is hinged to the sliding seat 33, and the other end of the tilting sleeve 32 is hinged to the rotating shaft 22; the sliding seat 33 is slidably installed within the rotating shaft 22 along its length. In specific implementation, the sliding seat 33 can be manually slid, thereby adjusting the angle between the tilting sleeve 32 and the tilting rod 31, while the tilting rod 31 adaptively slides within the tilting sleeve 32.

[0027] See Figures 1-4In other embodiments, an adjustment mechanism 5 is also included, which can adjust the sliding distance of the sliding seat 33. By adjusting the sliding distance of the sliding seat 33 through the adjustment mechanism 5, the angle of the tilting member 3 can be adjusted. Further, the adjustment mechanism 5 includes: a threaded sleeve 51, a threaded rod 52, and a driving member 53; the threaded sleeve 51 is fixedly connected to the sliding seat 33, the threaded rod 52 is rotatably connected to the rotating shaft 22, and the threaded rod 52 is threadedly connected to the threaded sleeve 51; the driving member 53 can drive the threaded rod 52 to rotate. In a specific implementation, the driving member 53 can be a motor; when the driving member 53 is activated, the driving member 53 drives the threaded rod 52 to rotate, and the threaded rod 52 drives the threaded sleeve 51 to move, thus driving the sliding seat 33 to slide, thereby realizing the adjustment of the sliding seat 33.

[0028] See Figures 1-4 In another embodiment, the rotating shaft 22 includes a rotating section 221, a plugging section 222, and a sealing section 223; the diameters of the plugging section 222 and the sealing section 223 are smaller than the diameter of the rotating section 221; one end of the plugging section 222 is fixedly connected to one end of the rotating section 221, and the plugging section 222 is configured to cooperate with the mounting hole 211; one end of the sealing section 223 is slidably plugged into the other end of the rotating section 221 along the length of the rotating section 221; the adjusting mechanism 5 is installed inside the rotating section 221, and the sealing section 223 is threadedly connected to the end of the threaded rod 52 away from the threaded sleeve 51; and the internal thread of the sealing section 223 is opposite in direction to that of the threaded sleeve 51; the sealing section 223 extends into the air blowing pipe 4.

[0029] In practice, the fan blade 24 is fixedly installed on the rotating section 221. The rotating section 221 and the insertion section 222 are hollow inside. The tilting rod 31 is hinged to the rotating section 221, and the tilting sleeve 32 extends into the insertion section 222. The driving component 53 drives the threaded rod 52 to rotate, and the threaded rod 52 can adjust the length of the sealing section 223. This allows for adjustment of the sealing size of the sealing section 223 on the connection port 41. In this way, the frequency and amplitude of the vibration can be further adjusted.
