Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, in particular to a lung exhalation training device for thoracic surgery patients. Background Art

[0002] After thoracic surgery, patients often experience symptoms such as shallow and rapid breathing and weak coughing due to surgical trauma, pain, and changes in intrathoracic pressure, which can easily lead to the occurrence of pulmonary complications. Therefore, lung exhalation training (or respiratory function training) is an important part of postoperative rehabilitation for thoracic surgery patients. The respiratory trainer can exercise the function of respiratory muscles, improve vital capacity and lung function. Exhalation training can enhance lung function and improve lung ventilation and gas exchange efficiency. Through abdominal breathing, pursed lip breathing, etc., patients can deepen their breathing and increase lung ventilation, thereby exercising respiratory muscles and improving lung function. This is especially important for patients after thoracic surgery, because surgery may affect the normal function of the lungs, and exhalation training helps to accelerate the recovery of lung function. At the same time, for patients after thoracic surgery, exhalation training can relax the respiratory muscles and diaphragm, which helps to reduce wound pain caused by breathing.

[0003] However, existing exhalation training usually only has simple training functions. Patients who use it for the first time do not know how to use the correct exhalation method for training. They may exhale too quickly and have a bad rhythm, which is not conducive to patients who have just completed thoracic surgery. The effect of rehabilitation training is greatly reduced. For this reason, we propose a lung exhalation training device for thoracic surgery patients. Summary of the invention

[0008] Among them, an exhaust groove is opened at the rear end of the main body, the external size of the plug plate coincides with the internal size of the exhaust groove, and two second sliding grooves are opened at the rear end of the plug plate. The two second sliding grooves are inclined and the second sliding grooves are slidably connected to the adjustment plate through an adjustment block.

[0009] Among them, a movable groove is opened inside the intake pipe, and a leak-proof plate is arranged inside the movable groove. The leak-proof plate is made of a gel-like material, and the shape of the leak-proof plate is set to be pointed. The outer wall of the leak-proof plate is movably connected with multiple movable balls at equal intervals, and the outer wall of the movable balls fits with the inner wall of the intake pipe.

With the help of this device, the patient can extend the exhalation time, assist the patient to keep exhaling slowly and evenly, so that the exhalation training effect can be effectively improved, and help patients quickly master the correct training skills.

[0016] 2. Patients can adjust the current in the three solenoid valves by adjusting the sliding rheostat according to their own training intensity, so as to adjust the resistance of the ball. The setting of adjusting the resistance improves the practicality of the device, reduces the use of springs in traditional exhalation trainers, makes the device more durable, and adjusts the resistance for patients to gradually increase the training time and intensity. After thoracic surgery, patients need to adjust the training intensity according to their own physical condition to avoid high-intensity training at the beginning, which may lead to respiratory muscle fatigue or injury.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0020] See also Figures 1 to 11 , the present invention provides a technical solution: a lung exhalation training device for thoracic surgery patients, comprising: a main body 001; Also includes: The air intake pipe 002 is arranged at the front end of the main body 001. The air intake pipe 002 can collect all the exhaled air of the patient during training into the main body 001; Training tubes 003, there are three training tubes 003, the three training tubes 003 are arranged in series about the outer wall of the main body 001, and the training tubes 003 are used to help the patient to perform training; The guide assembly 004 includes two guide assemblies 004, which are arranged between the three training tubes 003. The guide assembly 004 is used to adjust according to the patient's exhalation intensity. The guide assembly 004 includes a movable rod 401, which is rotatably connected to the main body 001. A slide groove 402 is provided at the bottom end of the movable rod 401, and a pressure block 403 is slidably connected inside the slide groove 402.

[0021] Both ends of the movable rod 401 are provided with fixed rings 410, and the fixed ring 410 is fixedly connected to the training tube 003. The upper fixed ring 410 is movably connected inside with an adjusting ring 420, and the external transmission of the adjusting ring 420 is connected with multiple transmission rings 430. The outer wall of the adjusting ring 420 is provided with tooth marks 440, and the adjusting ring 420 is meshed with an adjusting gear 450 through the tooth marks 440.

[0022] The bottom end of the adjusting gear 450 is fixedly connected to a connecting frame 460 , which is rotatably connected to the fixing ring 410 . A rotating rod 470 penetrates the bottom end of the connecting frame 460 , and a movable frame 480 is slidably connected to the outer wall of the rotating rod 470 . The movable frame 480 is fixedly connected to the movable rod 401 .

[0023] A positioning block 412 is disposed inside one side of the fixing ring 410 at the bottom. The lower end of the positioning block 412 is rotatably connected to the fixing ring 410 , and the upper end of the positioning block 412 is movably connected to the pressing block 403 .

[0024] Among them, after holding a breath, the patient blocks his mouth and presses the mouthpiece 230, exhales deeply, and the airflow passes through the air inlet pipe 002 and enters the interior of the main body 001. Due to the setting of the guide component 004, the small balls 320 of the second training tube 003 and the third training tube 003 are stuck, and the gas exhaled by the patient first enters the first training tube 003, and the air pressure makes the small ball 320 float in the first training tube 003. When the small ball 320 reaches the top of the first training tube 003, it contacts the transmission ring 430 at the top of the training tube 003. Under the rise of the small ball 320, the transmission ring 430 is driven to rotate in the upper direction of the small ball 320, that is, reversely, so that the transmission adjustment gear 450 rotates clockwise, and under the action of the connecting frame 460, the movable rod 401 is moved through the movable frame 480 at the same time, so that the movable rod 401 performs a swinging motion, and then the pressing block 403 at the bottom of the movable rod 401 rapidly descends along the direction of the slide groove 402; Subsequently, the descent of the pressing block 403 will drive the positioning block 412 movably connected thereto to rotate inside the fixing ring 410, and then the positioning block 412 will be retracted into the fixing ring 410. After the small ball 320 inside the second training tube 003 loses its fixation, the gas will also drive the second small ball 320 to rise inside the second training tube 003, and so on. All three small balls 320 can rise under the patient's exhalation. The patient can rely on the exhaled gas to keep the small ball 320 in the rising state as much as possible to exercise the expiratory muscles.

[0025] Therefore, the front end of the air intake pipe 002 is fixedly connected with a pad 210, the inside of the pad 210 is slidably connected with a pressing nozzle 230, the rear end of the pressing nozzle 230 is fixedly connected with a plurality of movable springs 240, and the pressing nozzle 230 is movably connected with the main body 001 through the movable springs 240.

[0026] Both ends of the pressing nozzle 230 are fixedly connected with a pressing plate 250, the rear ends of the two pressing plates 250 are fixedly connected with a connecting rod 260, the rear ends of the two connecting rods 260 are slidably connected with an adjusting plate 270, the outer wall of the adjusting plate 270 is provided with a first adjusting groove 280, the first adjusting groove 280 is inclined, the rear end of the adjusting plate 270 is fixedly connected with an adjusting block 290, a plug plate 291 is provided between the two adjusting blocks 290, and the plug plate 291 is movably connected to the main body 001.

[0027] Among them, the patient blocks the pressing nozzle 230 after normal inhalation, and the pressing nozzle 230 is forced to move backward, while driving the pressing plate 250 to press the connecting rod 260 backward. Since the rear end of the connecting rod 260 is slidably connected to the adjusting plate 270, the connecting rod 260 will drive the adjusting plate 270 to move along the direction of the first adjusting groove 280 during the movement of the connecting rod 260, so that the two adjusting plates 270 expand outward at the same time.

[0028] An exhaust groove 110 is provided at the rear end of the main body 001, and the outer dimensions of the plug plate 291 are consistent with the inner dimensions of the exhaust groove 110. Two second sliding grooves 292 are provided at the rear end of the plug plate 291. The two second sliding grooves 292 are inclined, and the second sliding grooves 292 are slidably connected to the adjustment plate 270 through the adjustment block 290.

[0029] Among them, when the two adjustment plates 270 move outward, under the action of the two second sliding grooves 292, the plug plate 291 can be driven to slide on the outer wall of the adjustment plate 270, and then the plug plate 291 moves toward the outside of the main body 001, blocking the tail end of the main body 001, that is, blocking the exhaust groove 110 of the main body 001, so that when the patient blows, the exhaled gas only circulates in the main body 001 and the training tube 003.

[0030] A movable groove 220 is opened inside the air intake pipe 002, and a leak-proof plate 221 is arranged inside the movable groove 220. The leak-proof plate 221 is made of a gelatinous material and is shaped as a pointed angle. A plurality of movable balls 222 are movably connected to the outer wall of the leak-proof plate 221 at equal intervals. The outer wall of the movable balls 222 fits with the inner wall of the air intake pipe 002. The diameter of the movable groove 220 is larger than the diameter of the inner wall of the air intake pipe 002. The rear end of the leak-proof plate 221 is fixedly connected to a fixed plate 223. The rear end of the fixed plate 223 is fixedly connected to a buffer spring 224. The buffer spring 224 is arranged inside the movable groove 220.

[0031] Among them, the leak-proof plate 221 blocks the entrance of the air inlet pipe 002. When the patient blows air, the air pressure presses the leak-proof plate 221 to move backward, and under the action of the movable ball 222, the friction between the leak-proof plate 221 and the main body 001 can be reduced, which facilitates the movement of the leak-proof plate 221. The tail end of the leak-proof plate 221 moves to the inside of the movable groove 220, so that a gap appears in the air inlet pipe 002, so that the air inlet pipe 002 is connected with the main body 001, and the gas exhaled by the patient will enter the inside of the main body 001. When the patient stops exhaling, the buffer spring 224 drives the leak-proof plate 221 back to its original position, quickly blocking the entrance of the air inlet pipe 002, preventing the exhaled gas from returning to the patient's mouth and increasing the risk of respiratory infection in the patient.

[0032] An air hole 310 is provided on the outer wall of the top end of the three training tubes 003, and a small ball 320 is arranged inside the three training tubes 003. A mounting groove 330 is provided on the top end of the small ball 320, and a magnetic sheet 340 is arranged inside the mounting groove 330. A mounting ring 350 is fixedly connected to the top end of the three training tubes 003, and an electromagnetic valve 360 ​​is installed inside the mounting ring 350, and a sliding rheostat 370 is installed between the three solenoid valves 360.

[0033] Among them, the three solenoid valves 360 are interconnected and have the same magnetic force. The solenoid valves 360 and the magnetic sheet 340 repel each other. The patient can adjust the sliding rheostat 370 to adjust the current in the three solenoid valves 360 according to his own training intensity. The larger the current, the stronger the magnetic field generated by the solenoid valve 360, and the greater the magnetic force. Therefore, the greater the resistance of the ball 320, the greater the training intensity of the patient, thereby improving the practicality of the device, which is suitable for exhalation training of patients with lung diseases, improving lung function, alleviating dyspnea, assisting in the treatment of respiratory diseases, improving the quality of life and preventing complications. Embodiment 2

[0034] like Figure 8In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the outer wall of the ball 320 is fixedly connected with a movable ring 321, and a positioning groove 322 is provided on the outer side of the movable ring 321. The inner size of the positioning groove 322 coincides with the outer size of the positioning block 412. The outer wall of the movable ring 321 fits the inner wall of the training tube 003. The outer wall of the movable ring 321 is provided with anti-wear material. The bottom ends of the three training tubes 003 are movably connected with an adjusting rod 323, and the adjusting rod 323 is slidably connected with the ball 320.

[0035] Among them, by setting the adjustment rod 323, it is convenient to limit the position of the ball 320, so that the movable ring 321 can be close to the inner wall of the training tube 003, preventing the ball 320 from contacting the training tube 003, thereby improving the durability of the ball 320. At the same time, the movable ring 321 is convenient for positioning the ball 320, so that the device can work stably.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
