Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an auxiliary sputum drainage device for the clinical treatment of elderly patients. Background Art

[0002] An auxiliary sputum drainage device for the clinical treatment of elderly patients is a medical device designed specifically for the elderly, aiming to help them more effectively drain sputum during the treatment of respiratory diseases. The device combines multiple functions to adapt to the physical conditions and treatment needs of elderly patients. It helps the elderly relieve the dyspnea caused by sputum accumulation through gentle and effective means, reducing the risk of lung infections. The design of the device takes into account the comfort and safety of the elderly, with simple operation and easy to use by medical staff and family members. In clinical treatment, the auxiliary sputum drainage device has become an important tool for improving the respiratory conditions of elderly patients and enhancing their quality of life, providing strong support for the treatment and rehabilitation of elderly respiratory diseases.

[0003] Traditional sputum drainage devices are widely used in the medical field. However, due to the limitations of their structures and working principles, there are often some problems that cannot be ignored. For example, traditional devices generally face the problem of single function. They mainly rely on mechanical vibration to help patients drain sputum. This single function mode often cannot be effectively adjusted according to the specific conditions of different patients and the characteristics of sputum, thus affecting the overall efficiency of sputum drainage. For example, for patients with relatively high sputum viscosity, simple vibration may not be sufficient to fully loosen the sputum, resulting in poor sputum drainage effect. In addition, multi-functional devices are large in size and cumbersome to operate, making them inconvenient to use. Moreover, the adaptability of traditional sputum drainage devices during positive pressure exhalation is limited, especially in terms of adjusting the vibration frequency. Positive pressure exhalation is a key link in the auxiliary sputum drainage process. It needs to adjust the vibration frequency according to the patient's breathing rhythm and sputum condition to achieve the best sputum drainage effect. However, many traditional devices cannot adjust the vibration frequency in real time during positive pressure exhalation, which means they cannot provide personalized treatment for each patient. This fixed vibration mode may not be suitable for all patients, especially for elderly patients with relatively weak respiratory functions or those sensitive to vibration, which may cause discomfort. Summary of the Invention

[0008] Further, the depth of the square groove matches the height of the lifting block, and the width of the through hole is greater than the maximum width of the rotating wheel.

[0009] Further, the butterfly valve unit includes a central shaft disposed on the inner wall of the air inlet, a first blade disposed in the middle of the central shaft, a second blade disposed at the end of the central shaft, and bumps symmetrically disposed on the inner wall of the air inlet.

[0010] Further, the position of the bump on the inner wall of the air inlet is higher than that of the first blade and the second blade, the shapes of the first blade and the second blade are semi-circular, and a butterfly valve unit is also provided in the middle of the long hole.

[0011] Further, the positive pressure mechanism includes a partition plate disposed at one end of the horizontal pipe away from the breathing hole, an orifice plate disposed on the side of the partition plate away from the breathing hole, a moving block disposed on the top of the orifice plate, a circular groove opened at one end of the long hole away from the breathing hole, a sliding groove opened at one end of the horizontal pipe away from the air inlet, a knob disposed inside the sliding groove, a bracket disposed at one end of the long hole close to the partition plate, a reed disposed on the top of the bracket, a strip hole opened on the top of the reed, a bidirectional lead screw disposed on the inner wall of the strip hole, the top of the bidirectional lead screw is fixedly connected to the bottom of the knob, an upper pressing block disposed on the top of the bidirectional lead screw, the bottom of the upper pressing block abuts against the reed, a lower pressing block disposed at the bottom of the bidirectional lead screw, the top of the lower pressing block abuts against the bottom of the reed, two guide posts symmetrically disposed at the bottom of the upper pressing block, and two guide holes symmetrically opened at both ends of the lower pressing block.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the atomization mechanism, the function of providing atomized liquid medicine during the patient's inhalation is realized. This design aims to help the patient better discharge sputum by inhaling the atomized liquid medicine. The atomized liquid medicine can directly reach the respiratory tract, dilute and loosen the sputum, making it easier to discharge.

During the treatment process, the patient inhales the atomized liquid medicine synchronously during inhalation, realizing the synchronization of treatment and sputum discharge and optimizing the treatment effect.

[0015] 2. By setting the positive pressure mechanism, which works in cooperation with the atomization mechanism, controls the exhalation resistance and generates vibration during the patient's exhalation, thereby promoting sputum discharge. At the same time, the device allows the vibration frequency to be adjusted to meet the needs of different patients. During exhalation, the increased resistance helps to push the sputum from the alveoli to the larger bronchi, and the vibration further loosens the sputum, making it easier to be discharged by coughing. By adjusting the vibration frequency, the patient can choose the most suitable vibration frequency according to their own comfort, which not only improves the sputum discharge efficiency but also ensures the comfort of the treatment process.

[0016] 3. By setting up the opening and closing unit, the patient can independently control the process of atomization therapy, which gives the patient greater freedom. The patient can decide whether to start atomization according to their own feelings and needs. When the patient feels short of breath or has difficulty discharging phlegm, they can turn on the opening and closing unit to start atomization therapy. When atomization is not needed, the patient can turn off the atomization and stop inhaling the medicine. This flexible control mechanism improves the convenience of treatment. Through independent regulation, the patient can obtain atomization therapy suitable for themselves at different times and in different states, thereby improving the breathing condition.

[0019] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0020] Example 1, referring to Figures 1-12 , which is the first embodiment of the present invention, provides an auxiliary sputum drainage device for the clinical treatment of elderly patients, including a horizontal tube 1, an atomization mechanism 2 installed at the bottom of the horizontal tube 1, and a positive pressure mechanism 3 installed at one end of the horizontal tube 1 away from the atomization mechanism 2; the positive pressure mechanism 3 is used to control the expiratory resistance of the patient and can generate vibration while exhaling; the atomization mechanism 2 includes a connecting ring 21 fixedly connected to the bottom of the horizontal tube 1, a vertical tube 22 fixedly connected to the middle of the horizontal tube 1 near the connecting ring 21, the liquid medicine at the bottom of the vertical tube 22 can move upward during the process of generating a pressure difference at the top, an opening and closing unit assembled at the top of the vertical tube 22 for controlling opening and closing, a breathing hole 23 opened at one end of the horizontal tube 1 away from the positive pressure mechanism 3, a fine hole 24 opened at one end of the breathing hole 23 close to the vertical tube 22, the flow rate of the fluid will increase during the process of passing through the fine hole 24, a long hole 25 opened at one end of the fine hole 24 away from the breathing hole 23, an air inlet 26 fixedly connected to the top of the horizontal tube 1, when a negative pressure is generated inside the long hole 25, the external air can flow into the inside of the horizontal tube 1 through the air inlet 26, a medicine bottle 27 meshingly connected to the bottom of the connecting ring 21, and a butterfly valve unit assembled inside the air inlet 26.

[0021] Specifically, the connecting ring 21 can fix the medicine bottle 27, enabling a stable connection between the medicine bottle 27 and the horizontal tube 1. The vertical tube 22 can guide the liquid medicine at the bottom to move upward through the pressure difference during the process of rapid air flow at the top. After the medicine is atomized, it will first diffuse through the breathing holes 23, avoiding cluster spraying and facilitating the patient's inhalation. The combination of the fine holes 24, the long holes 25, and the breathing holes 23 can form a Venturi tube, and the atomization of the liquid medicine is achieved by using the Venturi effect. The long holes 25 can form an air passage to realize the intake and exhaust of air when the patient breathes. After intake, it can guide the outside air into the interior of the long holes 25 during inhalation. The medicine bottle 27 can hold the liquid medicine, providing a drug reserve for the atomization of the patient. The setting of the atomization mechanism 2 realizes the function of providing atomized liquid medicine when the patient inhales. This design aims to help the patient better discharge sputum by inhaling the atomized liquid medicine. The atomized liquid medicine can directly reach the respiratory tract, dilute and loosen the sputum, making it easier to discharge. This method not only improves the sputum discharge efficiency but also enhances the patient's comfort. During the treatment process, when the patient inhales, the atomized liquid medicine is inhaled synchronously, realizing the synchronous progress of treatment and sputum discharge and optimizing the treatment effect.

[0022] Referring to Figures 2-6 , the opening and closing unit includes a stopper 28 rotatably connected to the inner wall of the top of the vertical tube 22, a variable-diameter hole 29 opened on the side of the horizontal tube 1 away from the air inlet 26, a sealing ring 210 rotatably connected to the side of the stopper 28 close to the variable-diameter hole 29, a rotating shaft 211 fixedly connected to the side of the stopper 28 away from the vertical tube 22, a torsion spring 212 fixedly connected to the side of the rotating shaft 211 close to the vertical tube 22, with both ends of the torsion spring 212 fixedly connected to the horizontal tube 1 and the rotating shaft 211 respectively, a runner 213 fixedly connected to the end of the rotating shaft 211 away from the vertical tube 22, a square groove 214 opened at the bottom of the horizontal tube 1, a lifting block 215 slidably connected to the inside of the square groove 214, a through hole 216 opened at the end of the lifting block 215 close to the rotating shaft 211, a plurality of racks 217 fixedly connected to the inner wall of the through hole 216 in a linear array, and a rubber block 218 fixedly connected to the bottom of the lifting block 215.

[0023] Specifically, the diameter of the block 28 matches the inner diameter of the vertical tube 22. When the block 28 is in a horizontal state, the vertical tube 22 can be blocked to prevent leakage of the liquid medicine. When the block 28 is in a vertical state, the blockage of the vertical tube 22 can be released. The sealing ring 210 can prevent the liquid medicine from penetrating into the interior of the variable diameter hole 29. The variable diameter hole 29 can provide a relatively closed space for the moving parts of the opening and closing unit. The rotating shaft 211 can transmit the power of the torsion spring 212. The torsion spring 212 can reset when the rotating shaft 211 is free from external force interference. The rotating wheel 213 can drive the rotating shaft 211 to rotate together while rotating. The square groove 214 can accommodate the internal movement of the lifting block 215. The lifting block 215 moves up and down through the rack 217 squeezes the rotating wheel 213 to make it rotate, and the rubber block 218 can prevent the patient's teeth from directly contacting the lifting block 215 to prevent the patient's teeth from being damaged. The patient can independently control the process of atomization treatment through the opening and closing unit, which gives the patient greater freedom and allows him to decide whether to start atomization according to his own feelings and needs. When the patient feels difficulty in breathing or sputum is difficult to discharge, the opening and closing unit can be turned on to start atomization treatment. When atomization is not needed, the patient can turn off the atomization and stop inhaling the medicine. This flexible control mechanism improves the convenience of treatment. Through autonomous regulation, the patient can obtain atomization treatment suitable for him at different times and states, thereby improving his breathing condition.

[0024] Reference Figure 2 and Figure 6 The depth of the square groove 214 matches the height of the lifting block 215 , and the width of the through hole 216 is greater than the maximum width of the rotating wheel 213 .

[0025] Specifically, the square groove 214 can move upward to the inside of the square groove 214 after being squeezed, and the through hole 216 can accommodate the rotating wheel 213 to rotate inside.

[0026] Reference Figure 2 and Figure 7 The butterfly valve unit includes a central shaft 219 fixedly connected to the inner wall of the air inlet 26, a blade 1 220 rotatably connected to the middle of the central shaft 219, a blade 221 rotatably connected to the end of the central shaft 219, and a protrusion 222 symmetrically fixedly connected to the inner wall of the air inlet 26.

[0027] Specifically, the central axis 219 can limit the position of the blade 1 220 and the blade 2 221 , so that the two can only rotate around the central axis 219 after being subjected to force.

[0028] Reference Figure 2 and Figure 7 The position of the protrusion 222 on the inner wall of the air inlet 26 is higher than the blade 1 220 and the blade 2 221 . The blade 1 220 and the blade 2 221 are semicircular in shape. A butterfly valve unit is also provided in the middle of the long hole 25 .

[0029] Specifically, due to the blockage of the bump 222, the rotation ranges of the first blade 220 and the second blade 221 will be limited. When the first blade 220 and the second blade 221 expand to the same plane, they can block the channel where they are located.

[0030] Example 2, refer to Figures 1-12 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the positive pressure mechanism 3 includes a partition plate 31 fixedly connected to the end of the horizontal pipe 1 far from the breathing hole 23, an orifice plate 32 rotatably connected to the side of the partition plate 31 far from the breathing hole 23, a moving block 33 fixedly connected to the top of the orifice plate 32, a circular groove 34 opened at the end of the long hole 25 far from the breathing hole 23, a sliding groove 35 opened at the end of the horizontal pipe 1 far from the air inlet 26, a knob 36 slidably connected to the inner side of the sliding groove 35, a bracket 37 fixedly connected to the end of the long hole 25 close to the partition plate 31, a reed 38 fixedly connected to the top of the bracket 37, a strip hole 39 opened at the top of the reed 38, a bidirectional lead screw 310 slidably connected to the inner wall of the strip hole 39, the top of the bidirectional lead screw 310 is fixedly connected to the bottom of the knob 36, an upper pressing block 311 abutted against the top of the bidirectional lead screw 310, the bottom of the upper pressing block 311 abuts against the reed 38, a lower pressing block 312 abutted against the bottom of the bidirectional lead screw 310, the top of the lower pressing block 312 abuts against the bottom of the reed 38, two symmetrically fixedly connected guide posts 313 at the bottom of the upper pressing block 311, and two symmetrically opened guide holes 314 at both ends of the lower pressing block 312.

[0031] Specifically, the partition plate 31 can block part of the air flow passing through the long hole 25, and the orifice plate 32 can also block part of the air flow. When the orifice plate 32 and the partition plate 31 are at different staggered angles, the size of the air flow channel in the long hole 25 can be controlled. The moving block 33 can drive the orifice plate 32 to move together while being pushed. The circular groove 34 can restrict the orifice plate 32 so that it can only rotate in place. The knob 36 can drive the bidirectional lead screw 310 to rotate and can move along the sliding groove 35. The sliding groove 35 can restrict the maximum stroke of the knob 36. The bracket 37 can fix one side of the reed 38 against the partition plate 31. The reed 38 will vibrate when blown by the air flow. The bidirectional lead screw 310 can perform linear motion under the guidance of the strip hole 39. By rotating the bidirectional lead screw 310, the upper pressing block 311 and the lower pressing block 312 can approach or move away from each other. Through the cooperation of the guide post 313 and the guide hole 314, the upper pressing block 311 and the lower pressing block 312 can move synchronously. The positive pressure mechanism 3 can cooperate with the atomization mechanism 2 to control the expiratory resistance and generate vibration when the patient exhales, thereby promoting the discharge of sputum. At the same time, the device allows the vibration frequency to be adjusted to meet the needs of different patients. During exhalation, the increased resistance helps to push the sputum from the alveoli to the larger bronchi, and the vibration further loosens the sputum, making it easier to be discharged by coughing. By adjusting the vibration frequency, the patient can choose the most suitable vibration frequency according to their own comfort, which not only improves the sputum discharge efficiency but also ensures the comfort of the treatment process.

[0032] Refer to Figure 9 , the length of the guide post 313 is equal to the length of the bidirectional lead screw 310, and the diameter of the guide post 313 matches the diameter of the guide hole 314.

[0033] Specifically, the top and bottom of the bidirectional lead screw 310 are the strokes of the upper pressing block 311 and the lower pressing block 312. Within the strokes of the upper pressing block 311 and the lower pressing block 312, the guide post 313 can play a constraining role.

[0034] Refer to Figure 10 , the connection between the knob 36 and the sliding groove 35 is spherical, and fan-shaped holes are symmetrically opened on one side of the orifice plate 32 close to the partition plate 31.

[0035] Specifically, the knob 36 is connected to the sliding groove 35 through a spherical part and can slide while rotating. The orifice plate 32 allows air to pass through through the fan-shaped holes, and the structure is the same as that of Embodiment 1.

[0036] Based on Examples 1-2, the working principle of the present invention is as follows: the medicine bottle 27 is filled with expectorant liquid, and the patient inhales by holding the end of the horizontal tube 1 close to the breathing hole 23 in his mouth when expectoration is needed. At this time, the interior of the horizontal tube 1 is in a negative pressure state, and the outside air enters the long hole 25 through the air inlet 26 and the partition 31. The air entering the long hole 25 from the partition 31 will push the blade 1 220 and the blade 2 221 in the long hole 25 to rotate and expand around the corresponding central axis 219 when passing through them. When the two expand to the maximum extent, they will be blocked by the corresponding protrusion 222 and stop rotating, thereby blocking the air circulation between the breathing hole 23 and the partition 31. The airflow entering the long hole 25 from the air inlet 26 will cause the blades in the air inlet 26 to rotate and expand around the corresponding central axis 219. The first blade 220 and the second blade 221 are close together to keep the air inlet 26 unobstructed. After the air enters the long hole 25, it enters the breathing hole 23 through the fine hole 24 and is inhaled into the body by the patient. While holding the horizontal tube 1, the patient can bite the rubber block 218 with his teeth. The rubber block 218 pushes the lifting block 215 to move up. While the lifting block 215 moves up, it drives the rotating wheel 213 to rotate through the rack 217. While the rotating wheel 213 rotates, the torsion spring 212 accumulates force, and the rotating shaft 211 can drive the stopper 28 to rotate. After the lifting block 215 moves up to the limit, it will be able to drive the stopper 28 to rotate ninety degrees through rotation, so that the stopper 28 releases the blockage of the vertical tube 22, so that the long hole 25 is connected with the medicine bottle 27 through the vertical tube 22. In the process of the airflow passing through the fine hole 24 In the process, since the passage becomes narrower, the flow rate will increase, so that the air pressure at the top of the vertical tube 22 is reduced, and the liquid medicine in the medicine bottle 27 will move upward under the action of the pressure difference and be brought into the fine hole 24 by the airflow. The liquid medicine is broken up and mixed with the airflow in the fine hole 24, thus becoming mist. After the mist liquid medicine enters the breathing hole 23, it diffuses and is inhaled into the body by the patient, thereby diluting the sputum. The patient releases the bite of the rubber block 218, and the torsion spring 212 will reset the stopper 28 and the lifting block 215 through the rotating shaft 211. At this time, no liquid medicine will move upward through the vertical tube 22 during the inhalation, so the atomization function is turned off. When the patient exhales, the air inlet 26 will be blocked by the corresponding butterfly valve unit. At this time, the long hole 25 and the partition 31 will remain unobstructed, and the airflow exhaled by the patient will pass through the reed 38. The reed 38 will generate vibration, and the vibration is transmitted to the patient's body through the air and the cross tube 1 to assist the patient in expectoration. When patients with different conditions and physical conditions need to adjust the vibration frequency, they can rotate the knob 36 to rotate the bidirectional screw rod 310. While the bidirectional screw rod 310 rotates, the upper pressing block 311 and the lower pressing block 312 move away from each other, thereby releasing the clamping of the reed 38. By pushing the knob 36 to move along the slide groove 35, the upper pressing block 311 and the lower pressing block 312 are driven to move in different directions by the bidirectional screw rod 310 while the knob 36 moves. The upper pressing block 311 and the lower pressing block 312 maintain synchronous movement under the constraints of the guide column 313 and the guide hole 314. After the knob 36 is moved to a suitable position, it is rotated in the opposite direction.The upper pressing block 311 and the lower pressing block 312 are brought closer to clamp the reed 38. The shorter the distance between the side of the reed 38 close to the fine hole 24 and the bidirectional lead screw 310, the higher the vibration frequency; conversely, the lower the vibration frequency. By rotating the moving block 33, the orifice plate 32 can be driven to rotate. The less the fan-shaped holes of the orifice plate 32 coincide with the holes of the partition plate 31, the slower the overall air flow speed, and the greater the force required for the patient to exhale; conversely, the smaller the force. By controlling the resistance of the patient's exhalation, it is easier for individual sputum to move from the alveoli to the larger bronchi, facilitating sputum discharge.
