Description

Technical Field

[0001] The present invention relates to the technical field of breath-holding training, and specifically to a breath-holding training device for synchronous detection of respiratory rhythm and heart rate. Background Art

[0002] Synchronous detection of respiratory rhythm and heart rate is a process of precisely monitoring and collecting data on the rhythm changes of human respiration and the frequency of heartbeats with the aid of specific devices and technologies. Doctors can comprehensively analyze the cardiopulmonary function based on the synchronous detection results to make correct assessments and treatment plans for the condition.

[0003] During some medical examinations and treatments, such as MRI / CT examinations and radiotherapy, irregular respiratory rhythms or poor breath-holding can affect the scanning time and imaging quality, and patients are required to cooperate with breath-holding. However, relying solely on patients' own breath-holding has poor effects, and patients will have involuntary breathing, resulting in interrupted breath-holding. At this time, a breath-holding training device is needed.

[0004] Currently, the breath-holding training devices on the market mainly consist of an abdominal belt, sensors, and a display screen. When in use, the sensors are tied to the abdomen with the abdominal belt to sense the respiratory rhythm, and the display screen can display the data read by the sensors. However, when using this device, some patients cannot effectively regulate their breathing, resulting in a short breath-holding time. To solve the above problems, existing technologies often add a guiding function to this device, which can guide patients during breath-holding training and increase the patients' breath-holding time. However, in the actual use process of this device, medical staff need to use straps to tie the device to the patient's abdomen, and the fixing work is rather cumbersome. Moreover, after the fixing is completed, it is not convenient for patients to adjust the tightness of the device, reducing the convenience of the device and not meeting the needs of users.

[0035] Refer to Figure 2 、 Figure 6 and Figure 7, the detection mechanism 3 includes a first rotating rod 301. A plurality of first rotating rods 301 are respectively rotatably connected at equal intervals to the front end inside the hollow plate 5. A wire winding reel 302 is fixedly connected to the front side of the outer wall of each of the plurality of first rotating rods 301. The first rotating rod 301 drives the wire winding reel 302 to rotate. A connecting wire 303 is arranged inside each of the wire winding reels 302. One end of each of the plurality of connecting wires 303 penetrates through the hollow plate 5 and is fixedly connected to an electrode piece 304. The electrode piece 304 can detect the heart rate of the patient. A transmission rod 305 is rotatably connected to the front end inside the hollow plate 5. A first gear 306 is fixedly connected to the rear end of the transmission rod 305. The transmission rod 305 drives the first gear 306 to rotate. A plurality of second rotating rods 307 are rotatably connected at equal intervals to the rear end inside the hollow plate 5. A second gear 308 is fixedly connected to the outer side of each of the plurality of second rotating rods 307. Each of the plurality of second gears 308 is meshed with the first gear 306. When the first gear 306 rotates, the second gear 308 drives the second rotating rod 307 to rotate. A transmission assembly is arranged on the front side of each of the plurality of second rotating rods 307. The transmission assembly includes a first transmission tooth 309. The first transmission tooth 309 is fixedly connected to the front end of the second rotating rod 307. A second transmission tooth 310 is slidably connected to the rear side of the outside of the first rotating rod 301. When the first transmission tooth 309 rotates, the second transmission tooth 310 drives the first rotating rod 301 to rotate. A connecting second spring 311 is arranged in the middle of the outside of the first rotating rod 301. The rear end of the second spring 311 is fixedly connected to the second transmission tooth 310.

A clamping groove 403 is opened in the middle of the left and right sides of the hollow plate 5. The two clamping blocks 402 are respectively engaged with the corresponding clamping grooves 403. When the clamping blocks 402 are engaged with the clamping grooves 403, the hollow plate 5 can be rotated. The inner part of the clamping block 402 is slidably connected with a sliding plate 404. A rotating component is arranged on the lower side of the inner part of the support frame 1, and the rotating component includes a two-way The threaded rod 405 is rotatably connected to the lower inner side of the support frame 1. The left and right sides of the outer wall of the two-way threaded rod 405 are threadedly connected with sliders 406. When the two-way threaded rod 405 rotates, the slider 406 moves accordingly. The bottom ends of the two sliding plates 404 penetrate the corresponding blocks 402 and are rotatably connected to the sliders 406. The sliders 406 can drive the blocks 402 to rotate through the sliding plates 404.

[0038] In the present invention, when the hollow plate 5 needs to be disassembled and the fixing belt 207 needs to be cleaned and repaired, the third knob 407 is rotated, and the third knob 407 drives the bidirectional threaded rod 405 to start rotating. As the threaded rod rotates, the slider 406 connected thereto moves along the bidirectional threaded rod 405. The slider 406 can drive the block 402 to rotate through the sliding plate 404. When the block 402 rotates, it can be disengaged from the engagement with the slot 403, so that the hollow plate 5 can be easily disassembled, reducing the workload of the staff.

[0039] Reference Figure 1 and Figure 3 The fixing mechanism 2 further includes a toggle block 220, which is fixedly connected to the top of the connecting rod 205.

Moreover, the loudspeaker 6 can play the pre-recorded breathing instructions to let the patient be familiar with the breathing instructions in advance and perform breath-holding training.

[0043] Working principle: When using this device, first rotate the connecting rod 205. The connecting rod 205 will drive the ratchet pawl 206 to rotate, so as to disengage from the ratchet wheel 204 and release the limit on the support rod 202. At this time, pull the fixing belt 207, wrap the fixing belt 207 around the patient's waist, and push the mounting piece 208, so that the first ratchet plate 209 is inserted into the plug-in block 210. The first spring 216 will push the second ratchet plate 214 to engage with the first ratchet plate 209, and the mounting piece 208 can be fixed, so that the device can be conveniently fixed on the patient's waist. When it is necessary to adjust the tightness, rotate the support rod 202. The support rod 202 drives the winding roller 203 to rotate, and the tightness of the fixing belt 207 can be conveniently adjusted. And when it is necessary to remove this device, pull the pull ring 219. The pull ring 219 can drive the front second ratchet plate 214 to move through the lever 218. The front second ratchet plate 214 can push the rear second ratchet plate 214 to move through the connecting plate 212. The second ratchet plates 214 on both sides will disengage from the engagement with the first ratchet plate 209, so as to remove the mounting piece 208. At this time, rotate the support rod 202, and the winding roller 203 can be driven to rotate, so as to wind the fixing belt 207 into the first hollow block 201;

[0044] When it is necessary to detect the heart rate of the patient, pull the electrode plate 304. The electrode plate 304 drives the wire winding reel 302 to rotate through the connecting wire 303, and the connecting wire 303 will elongate accordingly, so as to attach the electrode plate 304 to the patient's body, which is convenient for detecting the heart rate of the patient. And when it is necessary to retract the connecting wire 303, rotate the second knob 312. The second knob 312 drives the first gear 306 to rotate through the transmission rod 305. Since the second gear 308 meshes with the first gear 306, the second gear 308 will drive the second rotating rod 307 to rotate accordingly. The second rotating rod 307 drives the first transmission tooth 309 to rotate, and the second transmission tooth 310 drives the first rotating rod 301 to rotate, so as to drive the wire winding reel 302 to rotate, and the connecting wire 303 can be wound up. And when paying out the wire, the first transmission tooth 309 cannot drive the second transmission tooth 310 to rotate in the reverse direction, and the wire can be paid out for a single electrode plate 304;

[0045] When it is necessary to remove the hollow plate 5 and clean and repair the fixing belt 207, rotate the third knob 407. The third knob 407 will drive the bidirectional threaded rod 405 to rotate, and the slider 406 will move accordingly. When the slider 406 moves, it can drive the clamping block 402 to rotate through the sliding plate 404. When the clamping block 402 rotates, it can disengage from the clamping state with the clamping groove 403, and then the hollow plate 5 can be easily removed.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
