Description

Technical Field

[0001] The present invention relates to the technical field of postoperative care, and in particular to a breathing training tool after lung cancer surgery. Background Art

[0002] If cancer cells appear on the lungs, surgery can be performed to remove the affected area to prevent further spread of the cancer cells. In the early stages after lung resection, the patient's respiratory function will be affected to a certain extent, with symptoms such as wheezing and uneven breathing rate. These adverse conditions will gradually improve during the postoperative recovery phase. However, to improve the efficiency of postoperative recovery, patients will also use appropriate breathing training tools to assist in lung function training.

[0003] For example, the Chinese invention patent No. 201911085224.6 provides a breathing training device. The device is equipped with a breathing mouthpiece, a mounting cylinder, a purification component, a sliding cylinder, an adjustment rod, and a return spring. The sliding cylinder can slide in the mounting cylinder under the action of the pressure difference, and at the same time drive the valve stem to move to adjust the flow rate through the adjustment hole, thereby adjusting the impedance during breathing to exercise lung function. However, most traditional breathing training tools can only adjust the training intensity, but are not convenient for adjusting the breathing frequency according to the patient's specific situation. As a result, the recovery efficiency of postoperative patients is easily reduced due to the unstable breathing frequency and breathing speed during breathing. Summary of the Invention

[0024] 1. During use, this breathing training tool can be secured to the patient's chest via two sets of elastic straps and Velcro. A drive mechanism controls the rotation of a transmission disk within the housing, which in turn controls the sliding of two sets of sliders at both ends of the housing through the cooperation of two sets of rocker mechanisms. During the sliding process, the two sets of sliders control the expansion and contraction of the ends of the elastic straps within the housing, causing the ring formed by the elastic straps to cyclically expand and contract. The patient can adjust their breathing rate based on the expansion and contraction of the elastic straps and the changes in chest resistance, making their breathing more even and improving the efficiency of respiratory function rehabilitation. The position of the two sets of connecting blocks on the transmission disk can be adjusted according to the patient's chest expansion, thereby adjusting the sliding distance of the sliders and, therefore, the expansion and contraction range of the elastic straps, to accommodate different patients.

[0025] 2. When the breathing training tool is in use, the driving motor in the driving assembly drives the second driving gear to rotate during the rotation process, and then drives the second driven gear to rotate. Since the movement of the sliding frame is affected by the cooperation of the positioning rod and the positioning frame and can only move up and down, the second driven gear can drive the slider to slide up and down on one side of the sliding rheostat through the cooperation of the control column and the sliding frame during the rotation process, thereby adjusting the current of the indicator light circuit to control the synchronous change of the brightness of the indicator light while the elastic strap is retracted and extended. The patient can further adjust the breathing frequency and breathing amplitude according to the indication of the indicator light observed by the mirror, thereby further improving the efficiency of respiratory function rehabilitation.

[0041] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0042] Example:

[0043] like Figures 1 to 5 As shown, the present invention provides a breathing training tool for lung cancer surgery, comprising a housing 101 and a cover 107 fixed to one side thereof. A rotatable transmission disc 201 is disposed within the housing 101, with an annular groove 202 formed on both sides of the transmission disc 201. Two sets of brackets 103 are fixedly disposed within the housing 101, the two sets of brackets 103 being arranged opposite each other. The transmission disc 201 is rotatably clamped between the two sets of brackets 103 via the two sets of annular grooves 202. Rollers 104 are disposed within the brackets 103, which are clamped within the annular grooves 202 and contact the inner walls of the annular grooves 202. The transmission disc 201 is supported by the engagement of protrusions on the inner sides of the brackets 103 with the annular grooves 202 on the transmission disc 201, allowing the transmission disc 201 to rotate between the two sets of brackets 103. The rollers 104 reduce the friction between the brackets 103 and the transmission disc 201, making the rotation of the transmission disc 201 smoother.

[0044] A drive assembly for controlling the rotation of the transmission disc 201 is disposed within the housing 101. The drive assembly includes a drive motor 501, which is fixedly mounted within a support base 106 on one side of the card holder 103. A first driving gear 502 is fixedly mounted to the output shaft of the drive motor 501. The first driving gear 502 is disposed inside one of the card holders 103. A first driven gear 203 is disposed on the transmission disc 201, and the first driving gear 502 meshes with the first driven gear 203. By controlling the start-up of the drive motor 501, the first driving gear 502 is driven to rotate inside one of the card holders 103. The rotation of the transmission disc 201 is then controlled by the cooperation between the first driving gear 502 and the first driven gear 203.

[0045] like Figure 2 、 4 As shown, in this embodiment, slidably mounted connecting blocks 303 are provided on both sides of the transmission disk 201, and slidably mounted sliders 401 are provided on both ends of the inner side of the housing 101. Each set of connecting blocks 303 is connected to one set of sliders 401 via a rocker mechanism, controlling the reciprocating sliding of the sliders 401 at one end of the housing 101. The rocker mechanism includes a transmission rod 308, a mounting post 307 provided on one side of the connecting block 303, and a hinged seat 402 provided on one side of the slider 401. The ends of the transmission rod 308 are hingedly connected to the mounting post 307 and the hinged seat 402, respectively.

[0046] During the rotation of the transmission disk 201, the two sets of connecting blocks 303 can be driven to rotate accordingly, so that the mounting column 307 on one side of the connecting block 303 rotates along the center of the circle of the transmission disk 201. The mounting column 307, the transmission rod 308 and the slider 401 cooperate to form a crank rocker structure, and then the two sets of sliders 401 can be driven to slide back and forth at the two ends of the inner side of the shell 101 by controlling the rotation of the transmission disk 201.

[0047] One end of each of the two sets of sliders 401 is provided with an elastic strap 405 connected by a connecting shaft 404. One side of the two sets of elastic straps 405 can be connected by a Velcro 406. The Velcro 406 cooperates to bind the breathing training tool to the outside of the patient's chest cavity. During the reciprocating sliding of the two sets of sliders 401 at both ends of the inner side of the housing 101, the one end of the two sets of elastic straps 405 is controlled to move within the housing 101, thereby controlling the ring formed by the two sets of elastic straps 405 to retract and expand at a certain frequency. The patient can adjust the breathing frequency and breathing intensity according to the retraction and expansion of the two sets of elastic straps 405 and the changes in the force on the chest cavity, thereby improving the efficiency of respiratory function rehabilitation.

[0048] like Figure 1 、 5As shown in , 6, in the present embodiment, the two groups of connecting blocks 303 are connected to the transmission disk 201 through an adjusting component, which includes a bidirectional screw 301, and mounting grooves 205 are provided on both sides of the transmission disk 201. The two groups of connecting blocks 303 are slidably clamped in the two groups of mounting grooves 205, and both ends of the bidirectional screw 301 are rotatably passed through the two groups of mounting grooves 205. The two groups of connecting blocks 303 are respectively sleeved on the two ends of the bidirectional screw 301 and engaged with them through threads. A first bevel gear 302 is provided on the bidirectional screw 301; a mounting frame 204 is provided in the transmission disk 201, and a rotatable second bevel gear 305 is provided in the mounting frame 204. The second bevel gear 305 meshes with the first bevel gear 302, and an adjusting knob 306 is provided on one side of the second bevel gear 305. A through hole 109 is provided on one side of the cover body 107, and an openable shielding cover 108 is provided on one side of the cover body 107.

[0049] After the shielding cover 108 is opened, the second bevel gear 305 can be rotated by adjusting the knob 306. During the rotation process, the second bevel gear 305 controls the rotation of the bidirectional screw 301 by meshing with the first bevel gear 302. Since the threads at both ends of the bidirectional screw 301 rotate in opposite directions and respectively engage with the two sets of connecting blocks 303 through threads, the two sets of connecting blocks 303 can be controlled to move in opposite directions within the two sets of mounting slots 205, respectively, to adjust the distance between the connecting blocks 303 and the center of the transmission disk 201. In this way, the movement distance of the slider 401 is adjusted, that is, the retraction and extension range of the elastic band 405 is adjusted to adapt to the expansion range of the chest cavity of different patients during breathing, thereby improving the applicability of the breathing training tool.

[0050] like Figure 5 、 6 As shown, in this embodiment, positioning blocks 304 are provided on both sides of the connecting block 303, and first positioning grooves 206 are provided on both sides of the inner wall of the mounting groove 205. The connecting block 303 is slidably connected to the mounting groove 205 by two sets of positioning blocks 304 being retained within the two sets of first positioning grooves 206. The cooperation between the positioning blocks 304 and the first positioning grooves 206 positions the movement of the connecting block 303, preventing the connecting block 303 from shifting during movement, thereby improving the stability of the internal structure of the respiratory training tool.

[0051] like Figure 3 、 4As shown, in this embodiment, second positioning grooves 403 are formed at both ends of the slider 401, and two sets of positioning ridges 102 are provided on the inner sides of both ends of the housing 101. The slider 401 is slidably connected to the housing 101 by being clamped on the two sets of positioning ridges 102 by the two sets of second positioning grooves 403. The cooperation between the second positioning grooves 403 and the positioning ridges 102 positions the slider 401 during movement, preventing the slider 401 from slipping during movement, and further improving the stability of the internal structure of the breathing training tool.

[0052] like Figure 2 、 3 As shown in Figures 7 and 8, an indication assembly is provided in the shell 101, and the indication assembly includes an indicator light 110 fixedly provided on one side of the cover body 107, a second driving gear 503 is fixedly installed on the output shaft of the drive motor 501, a second driven gear 504 rotatably mounted through an axis and a sliding frame 506 slidably mounted are provided on one side of the card frame 103, a control column 505 on one side of the second driven gear 504 is slidably clamped in the sliding frame 506, a slide 509 is provided on one side of the sliding frame 506, a sliding rheostat 508 is provided on the inner side of the cover body 107, the slide 509 is in contact with the coil of the sliding rheostat 508, the indicator light 110, the terminal of the sliding rheostat 508, the slide 509 and the internal power supply (not shown) and the switch (not shown) are connected in series, and the drive motor 501 is connected in series with the internal power supply and the switch.

[0053] The driving motor 501 controls the rotation of the first driving gear 502 while driving the second driving gear 503 to rotate synchronously on one side of the card frame 103, and then controls the rotation of the second driven gear 504 through the engagement of the second driving gear 503 with the second driven gear 504. Since the slide frame 506 can only move up and down due to the cooperation of the positioning rod 105 and the positioning frame 507, the second driven gear 504 can drive the slider 509 to reciprocate up and down on one side of the coil of the sliding rheostat 508 through the cooperation of the control column 505 and the slide frame 506 during the rotation process. During the movement, the slide 509 adjusts the current passing through the indicator light 110, thereby controlling the brightness of the indicator light 110 to change. The tooth ratio of the first driving gear 502 to the first driven gear 203 is equal to the tooth ratio of the second driving gear 503 to the second driven gear 504, so that the brightness change of the indicator light 110 is synchronized with the retraction and extension of the elastic band 405, so that the patient can adjust the breathing frequency according to the indication of the indicator light 110 observed through the mirror, making the patient's breathing more even, thereby improving the practicality of the breathing training tool.

[0054] Specific usage and beneficial effects of the present invention:

[0055] When in use, the breathing training tool is fixed to the patient's chest through the cooperation of Velcro 406 and two sets of elastic straps 405, and controls the drive motor 501 to start, driving the first driving gear 502 and the second driving gear 503 to rotate simultaneously. During the rotation process, the first driving gear 502 controls the rotation of the transmission disk 201 by cooperating with the first driven gear 203. During the movement, the transmission disk 201 drives the two sets of connecting blocks 303 to rotate simultaneously. Then, through the cooperation of the mounting post 307 and the transmission rod 308 on one side of the connecting block 303, the slider 401 is controlled to slide back and forth at one end of the housing 101. During the movement of the two sets of sliders 401, the belt loop formed by the two sets of elastic straps 405 can be controlled to be retracted and extended. The patient can adjust the breathing frequency according to the frequency and amplitude of the elastic straps 405, making the patient's breathing more even and improving the efficiency of respiratory function rehabilitation.

[0056] When using the breathing training tool, the shielding cover 108 can be opened and the adjusting knob 306 can be turned to drive the second bevel gear 305 to rotate. During the rotation, the second bevel gear 305 controls the bidirectional screw 301 to rotate in the two groups of mounting grooves 205 through the engagement with the first bevel gear 302. During the rotation, the bidirectional screw 301 controls the two groups of connecting blocks 303 to slide in the two groups of mounting grooves 205 respectively through the reverse threads at both ends thereof, so as to adjust the distance between the connecting block 303 and the center of the transmission disk 201, thereby adjusting the retraction and extension range of the elastic strap 405 to adapt to patients with different chest expansion ranges during breathing.

[0057] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
