Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a mechanical vibration-assisted sputum drainage device and method. Background Art

[0002] A vibration sputum drainage machine is a machine that loosens sputum through vibration to facilitate expectoration. When sputum is thick and difficult to expectorate in medicine, vibration sputum drainage is used as one of the treatment methods clinically. Vibration sputum drainage can make sputum easier to expectorate, facilitate the control of pneumonia, and reduce the risk of endotracheal intubation.

[0003] After retrieval, a patent with the Chinese patent application number CN221013877U discloses a vibration-assisted sputum drainage device, including a main body of the auxiliary sputum drainage device. The following deficiencies exist in the circumferential rotating shaft and the vibration generating roller in the above patent: Since the length of the circumferential rotating shaft and the mass of the vibration generating roller are both fixed, the rotation of the vibration generating roller around the circumferential rotating shaft as the radius driven by the rotating motor generates vibration, and the vibration frequency of this vibration is fixed. For different patients, there are differences in the tolerance and sputum drainage effect of this vibration frequency. Summary of the Invention

[0008] By providing a box body, a back pad, a front chest pad, a vibration mode switching module and an amplitude adjustment module, the device can change the vibration frequency of the device on the patient's chest by switching between a single-tooth rotating wheel, a double-tooth rotating wheel and a triple-tooth rotating wheel through the vibration mode switching module, thereby improving the adaptability of the device to the patient, so that the device can provide good treatment effects and experiences when facing patients with different vibration tolerances.

[0009] In a preferred embodiment, the movable rod is located inside the box body. A stabilizing frame is slidably connected to the outside of the movable rod.

Two symmetric second springs are fixedly connected to the outside of the guiding buckle. One ends of the second springs away from the guiding buckle are fixedly connected to the inner wall of the locking ring; a limiting rod is arranged on the outside of the locking ring. One side of the limiting rod is in contact with the locking ring. One end of the limiting rod is movably connected to a convex platform.

A single-tooth rotating wheel, a double-tooth rotating wheel and a triple-tooth rotating wheel are fixedly connected to the outside of the rotating shaft. A slide rail is fixedly connected to the inner wall of one side of the box body away from the lead screw. A sliding seat is slidably connected in the slide rail. A first motor is fixedly connected to the outside of the sliding seat. The output end of the first motor is connected to one side of the contact block away from the lead screw through a coupling. A contact block is arranged on the movable rod. The contact block and the double-tooth rotating wheel are in the same plane.

[0010] By providing a vibration mode switching module, the vibration mode switching module can use the single-tooth rotating wheel, the double-tooth rotating wheel and the double-tooth rotating wheel to enable the device to quickly switch the vibration mode, reducing the operation difficulty, shortening the waiting time of the patient, improving the treatment efficiency. Using the locking ring, the rack can lock the external toothed ring, ensuring the convenience of mode switching while reducing the probability of the single-tooth rotating wheel, the double-tooth rotating wheel and the triple-tooth rotating wheel disengaging from the contact block, ensuring the stable operation of the device and enhancing the reliability.

[0011] In a preferred embodiment, a rectangular groove is formed in the movable rod, and a supporting plate is slidably connected in the rectangular groove.

Two symmetric moving blocks are arranged on the outside of the bidirectional threaded rod, push rods are movably connected to the outside of the two moving blocks, and the ends of the two push rods away from the moving blocks are movably connected to the bottom of the supporting plate.

[0012] By providing an amplitude adjustment module, the amplitude adjustment module uses the bidirectional threaded rod and the moving block to change the contact time between the contact block and the rotating teeth of the device, so as to change the energy storage time of the spring I, thereby controlling the amplitude. While ensuring the treatment effect, the device takes into account the tolerance of the patient, effectively reducing the resistance of the patient and making the treatment process smoother.

[0013] A mechanical vibration-assisted sputum drainage method uses a mechanical vibration-assisted sputum drainage device as described above, and includes the following steps:

[0014] Step 1: After wearing the back pad and the front chest pad on the patient through the elastic band I, adjust the shoulder strap I and the shoulder strap II to make the back pad and the front chest pad fit the patient's body. Put the heating plate around the patient's neck, start the heating plate, and attach the box body to the back pad or the front chest pad so that the box body is located at the thoracic part of the patient. Use the vibration mode switching module to vibrate the patient's chest, and adjust the vibration frequency using the vibration mode switching module during vibration.

[0015] Step 2: During the process of vibrating and draining sputum, when the patient feels discomfort with the vibration amplitude, use the amplitude adjustment module to control the amplitude.

[0016] As can be seen from the above, a mechanical vibration-assisted sputum drainage device provided by the present invention can change the vibration frequency of the device on the patient's chest by switching between a single-tooth rotating wheel, a double-tooth rotating wheel, and a triple-tooth rotating wheel, thereby improving the adaptability of the device to the patient and enabling the device to provide good treatment effects and experiences for patients with different vibration tolerances.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0026] A mechanical vibration-assisted sputum drainage device disclosed in the present invention is mainly applied to scenarios where the applicability of existing mechanical vibration-assisted sputum drainage devices is poor.

One-sided hook-and-loop fasteners are arranged on the opposite sides of the back pad 2 and the front chest pad 4, and two symmetrical loop-and-loop fasteners are arranged on the side of the box body 1 close to the back pad 2. The side of the box body 1 opposite to the back pad 2 is attached. An observation window 12 is opened on the side of the box body 1 away from the back pad 2.

[0028] The vibration mode switching module 8 includes a movable rod 803 and an impact block 804;

[0029] The amplitude adjustment module 9 includes a rectangular groove 901 and a supporting plate 902.

[0030] Specifically, after wearing the back pad 2 and the front chest pad 4 on the patient through the first elastic band 5, adjust the first shoulder strap 3 and the second shoulder strap 6 to make the back pad 2 and the front chest pad 4 fit the patient's body. Put the heating plate 10 around the patient's neck, start the heating plate 10, and attach the box body 1 to the back pad 2 or the front chest pad 4 so that the box body 1 is located at the thoracic part of the patient. Use the vibration mode switching module 8 to vibrate the patient's chest. During vibration, use the vibration mode switching module 8 to adjust the vibration frequency. During the process of vibrating and draining sputum, when the patient feels discomfort with the vibration amplitude, use the amplitude adjustment module 9 to control the amplitude; the device can change the vibration frequency of the device on the patient's chest by switching between the single-tooth rotating wheel 819, the double-tooth rotating wheel 820 and the three-tooth rotating wheel 821 by using the vibration mode switching module 8, so as to improve the adaptability of the device to the patient, so that the device can provide good treatment effects and experiences for patients with different vibration tolerances.

[0031] Refer to Figure 3 , Figure 4 and Figure 5, in a preferred embodiment, the movable rod 803 is located inside the box body 1. A stabilizing frame 802 is slidably connected to the outside of the movable rod 803. One side of the stabilizing frame 802 opposite to the inner wall of the box body 1 is connected by bolts. A round opening is formed on one side of the box body 1 close to the stabilizing frame 802. A rubber sheet 801 is connected to the inner wall of the round opening by bolts. One side of the movable rod 803 close to the box body 1 is connected to the outside of an impact block 804 by bolts, and the outside of the impact block 804 is in contact with the outside of the rubber sheet 801. One side of the movable rod 803 away from the impact block 804 is connected to an adapter plate 806 by bolts; a first spring 805 is connected to the outside of the adapter plate 806 by bolts. One end of the first spring 805 away from the adapter plate 806 is connected to the outside of the stabilizing frame 802 by bolts. A round hole is formed on the outside of the box body 1. A lead screw 807 is arranged in the round hole. An external tooth ring 808 is arranged on the outside of the lead screw 807. The external tooth ring 808 is located outside the box body 1, and one side of the external tooth ring 808 opposite to the outside of the box body 1 is rotatably connected by a bearing. A locking ring 809 is arranged on the outside of the external tooth ring 808; one side of the locking ring 809 opposite to the outside of the box body 1 is slidably connected. A rack 810 is connected to the inner wall of the locking ring 809 by bolts. The rack 810 is engaged with the external tooth ring 808. A guide buckle 811 is slidably connected to the outside of the locking ring 809. One side of the guide buckle 811 opposite to the box body 1 is connected by bolts. One side of the lead screw 807 away from the box body 1 is connected to a knob 813 by bolts. Two symmetric second springs 812 are connected to the outside of the guide buckle 811 by bolts. One end of each of the second springs 812 away from the guide buckle 811 is connected to the inner wall of the locking ring 809 by bolts; a limiting rod 814 is arranged on the outside of the locking ring 809. One side of the limiting rod 814 is in contact with the locking ring 809. One end of the limiting rod 814 is rotatably connected by a bearing to a convex platform. One side of the convex platform away from the box body 1 is connected to an elastic reed 815 by bolts. One end of the elastic reed 815 away from the convex platform is connected to the outside of the limiting rod 814 by bolts. One end of the limiting rod 814 away from the elastic reed 815 is engaged with a clamping seat 816. One side of the clamping seat 816 opposite to the box body 1 is connected by bolts; one end of the lead screw 807 away from the knob 813 is rotatably connected by a bearing to a rotating shaft 818. A single-tooth rotating wheel 819, a double-tooth rotating wheel 820 and a triple-tooth rotating wheel 821 are connected to the outside of the rotating shaft 818 by bolts. A slide rail 822 is connected to the inner wall of one side of the box body 1 away from the lead screw 807 by bolts. A sliding seat 823 is slidably connected in the slide rail 822. A first motor 824 is connected to the outside of the sliding seat 823 by bolts. The output end of the first motor 824 is connected to one side of a contact block 817 away from the lead screw 807 by a coupling. A contact block 817 is arranged on the movable rod 803. The contact block 817 and the double-tooth rotating wheel 820 are in the same plane.

[0032] Specifically, when performing vibration sputum drainage treatment on a patient, the first motor 824 is started. The first motor 824 drives the rotating shaft 818 to rotate, so that the teeth on the double-toothed rotating wheel 820 push the contact block 817 during rotation, causing the contact block 817 to drive the movable rod 803 to move away from the rubber sheet 801, thereby storing energy in the first spring 805. After the teeth on the double-toothed rotating wheel 820 rotate and no longer contact the contact block 817, the energy of the first spring 805 is released, driving the impact block 804 on the movable rod 803 to impact the rubber sheet 801, causing the rubber sheet 801 to transmit the vibration to the thoracic part of the patient. When it is necessary to change the impact frequency, the limit rod 814 is pulled out against the elastic force of the elastic reed 815, and the locking ring 809 is pushed against the elastic force of the second spring 812, so that the rack 810 on the locking ring 809 releases the locking of the external toothed ring 808. The knob 813 is rotated to move the lead screw 807 to the outside or inside of the box body 1, thereby pushing the single-toothed rotating wheel 819 and the three-toothed rotating wheel 821 on the rotating shaft 818 to move to the same plane as the contact block 817. After the change is completed, the locking ring 809 is released, and the limit rod 814 is reinserted into the positioning seat 816.

[0033] In a specific application scenario, the vibration mode switching module 8 is mainly applicable to the vibration mode switching link during the vibration mode switching process. That is, the vibration mode switching module 8 can enable the device to quickly switch the vibration mode by using the single-toothed rotating wheel 819, the double-toothed rotating wheel 820, and the three-toothed rotating wheel 821, reducing the operation difficulty, reducing the waiting time of the patient, and improving the treatment efficiency. The rack 810 can lock the external toothed ring 808 by using the locking ring 809. While ensuring the convenience of mode switching, it reduces the probability of the single-toothed rotating wheel 819, the double-toothed rotating wheel 820, and the three-toothed rotating wheel 821 separating from the contact block 817, ensuring the stable operation of the device and improving the reliability.

[0034] Refer to Figure 6 and Figure 7, in a preferred embodiment, a rectangular groove 901 is formed on the movable rod 803. A support plate 902 is slidably connected in the rectangular groove 901. The upper side of the support plate 902 is bolted to the bottom of the contact block 817. And two symmetric elastic bands 5 are bolted between the back pad 2 and the front chest pad 4. Two symmetric shoulder straps 3 are bolted to the upper side of the back pad 2. Smooth magic tapes 2 are arranged on the shoulder straps 3. Two symmetric shoulder straps 6 are bolted to the upper side of the front chest pad 4. Hairy magic tapes 2 are arranged on the shoulder straps 6. The opposite sides of the shoulder strap 3 and the shoulder strap 6 on the same side are attached to each other; two symmetric supports 903 are bolted to the bottom of the rectangular groove 901. The same bidirectional threaded rod 904 is rotatably connected to the two supports 903 through bearings. The inner wall of the rectangular groove 901 is bolted with a second motor 905. The output end of the second motor 905 is connected to one side of the bidirectional threaded rod 904 through a coupling. And two symmetric heating plates 10 are arranged above the back pad 2. Two symmetric elastic bands 11 are bolted to the outside of the two heating plates 10. A braided belt 7 is bolted to the bottom of one of the heating plates 10. One end of the braided belt 7 away from the heating plate 10 is bolted to the upper side of the box body 1; two symmetric moving blocks 906 are arranged on the outside of the bidirectional threaded rod 904. Push rods 907 are rotatably connected to the outside of the two moving blocks 906 through bearings. And one end of the two push rods 907 away from the moving blocks 906 is rotatably connected to the bottom of the support plate 902 through a bearing.

[0035] Specifically, when the patient feels discomfort with the amplitude or the vibration feeling is weak, the second motor 905 is started. The second motor 905 drives the bidirectional threaded rod 904 to rotate, so that the moving block 906 moves on the bidirectional threaded rod 904. The moving moving block 906 pulls the push rod 907, so that the included angle between the push rod 907 and the bidirectional threaded rod 904 changes, thereby driving the support plate 902 to move up and down on the rectangular groove 901, so that the contact time between the contact block 817 connected to the support plate 902 and the teeth on the double-toothed rotating wheel 820 changes, thereby changing the amplitude.

[0036] In a specific application scenario, the amplitude adjustment module 9 is mainly applicable to the amplitude adjustment link in the amplitude adjustment process. That is, the amplitude adjustment module 9 uses the bidirectional threaded rod 904 and the moving block 906 to change the contact time between the contact block 817 and the rotating teeth of the device, so as to change the energy storage time of the first spring 805, thereby controlling the amplitude, making the device take into account the patient's tolerance while ensuring the treatment effect, effectively reducing the patient's resistance, and making the treatment process smoother.

[0037] A mechanical vibration-assisted sputum drainage method uses a mechanical vibration-assisted sputum drainage device as described above, including the following steps:

[0038] Step 1: After wearing the back pad 2 and the front chest pad 4 on the patient through the first elastic band 5, adjust the first shoulder strap 3 and the second shoulder strap 6 so that the back pad 2 and the front chest pad 4 fit the patient's body. Put the heating plate 10 around the patient's neck, start the heating plate 10, attach the box body 1 to the back pad 2 or the front chest pad 4 so that the box body 1 is located at the thoracic part of the patient. Use the vibration mode switching module 8 to vibrate the patient's chest. When vibrating, use the vibration mode switching module 8 to adjust the vibration frequency (when performing vibration-assisted sputum drainage treatment on the patient, start the first motor 824. The first motor 824 drives the rotating shaft 818 to rotate, so that the teeth on the double-toothed rotating wheel 820 push the contact block 817 when rotating, and the contact block 817 drives the movable rod 803 to move away from the rubber sheet 801, thereby storing energy in the first spring 805. After the teeth on the double-toothed rotating wheel 820 stop contacting the contact block 817, the energy of the first spring 805 is released, driving the impact block 804 on the movable rod 803 to impact the rubber sheet 801, so that the rubber sheet 801 transmits the vibration to the patient's chest. When it is necessary to change the impact frequency, pull out the limit rod 814 against the elastic force of the elastic reed 815, push the locking ring 809 against the elastic force of the second spring 812, so that the rack 810 on the locking ring 809 releases the locking of the external toothed ring 808, rotate the knob 813, so that the lead screw 807 moves to the outside or inside of the box body 1, thereby pushing the single-toothed rotating wheel 819 and the three-toothed rotating wheel 821 on the rotating shaft 818 to move to the same plane as the contact block 817. After the change is completed, release the locking ring 809 and insert the limit rod 814 back into the positioning seat 816);

[0039] Step 2: During the vibration-assisted sputum drainage process, when the patient feels discomfort with the vibration amplitude, use the amplitude adjustment module 9 to control the amplitude (when the patient feels discomfort with the amplitude or the vibration sensation is weak, start the second motor 905. The second motor 905 drives the bidirectional threaded rod 904 to rotate, so that the moving block 906 moves on the bidirectional threaded rod 904. The moving moving block 906 pulls the push rod 907, so that the angle between the push rod 907 and the bidirectional threaded rod 904 changes, thereby driving the supporting plate 902 to move up and down in the rectangular groove 901, so that the contact time between the contact block 817 connected to the supporting plate 902 and the teeth on the double-toothed rotating wheel 820 changes, thereby changing the amplitude).
