Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a cardiopulmonary rehabilitation exercise device for patients undergoing thoracic surgery. Background Art

[0002] After a patient undergoes thoracic surgery, in order to prevent complications such as pulmonary infection or atelectasis and improve respiratory function, it is necessary to actively carry out cardiopulmonary rehabilitation exercises. Among them, respiratory rehabilitation exercise is an important exercise method for cardiopulmonary rehabilitation exercise.

[0003] Currently, patients can choose to use a respiratory trainer for respiratory rehabilitation exercises. The respiratory trainer mainly consists of a hose and an instrument housing. Before use, connect the hose to the interface of the instrument housing, and connect the mouthpiece to the other end of the hose. When using, the patient holds the mouthpiece and exhales deeply. The patient can observe that the indicator ball inside the instrument housing floats up. After the exhalation ends, release the mouthpiece and inhale. After the breathing is balanced, repeat the breathing training multiple times. However, when the patient switches between exhalation and inhalation, the saliva in the patient's oral cavity may enter the respiratory trainer through the hose, easily resulting in a large number of bacteria inside the respiratory trainer, bringing adverse effects such as infection to the patient.

[0004] In view of this, we have designed a cardiopulmonary rehabilitation exercise device for patients undergoing thoracic surgery that can prevent saliva from entering the inside of the respiratory trainer. Summary of the Invention

Detailed implementation manners

[0036] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which the currently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present invention to those skilled in the art.

[0037] Embodiment 1:

[0038] A cardiopulmonary rehabilitation exercise device for patients undergoing thoracic surgery, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a breathing trainer 1, a fixed ventilation pipe 2, a transparent air intake hose 3, a first fixed block 4, a fixed rod 5, a rotating block 6, a clamping block 7, a connecting rod 8, a toggle block 9, a support rod 10 and a compression spring 11. The breathing trainer 1 is made of transparent material, and three cavities are opened inside the breathing trainer 1. Indicator balls are placed in the cavities of the breathing trainer 1. The fixed ventilation pipe 2 is connected to the upper right part of the breathing trainer 1, and the transparent air intake hose 3 is sleeved on the fixed ventilation pipe 2. The transparent air intake hose 3 is connected to the fixed ventilation pipe 2. The first fixed block 4 is fixedly connected to the upper right part of the breathing trainer 1. Two horizontally symmetrically arranged fixed rods 5 are fixedly connected to the first fixed block 4. Rotating blocks 6 are installed on the fixed rods 5 through bearings. Clamping blocks 7 are installed on the upper part of the rotating blocks 6 through bearings. The two clamping blocks 7 are mutually close to each other on one side. The clamping blocks 7 are clamped and fixed to the sleeve joints of the fixed ventilation pipe 2 and the transparent air intake hose 3. The clamping blocks 7 are all arranged in an arc shape with a high degree of fit with the transparent air intake hose 3. The inner sides of the clamping blocks 7 are fixed with rubber pads to prevent the clamping blocks 7 from wearing the sleeve joints of the fixed ventilation pipe 2 and the transparent air intake hose 3, and are also beneficial to sealing the sleeve joints of the fixed ventilation pipe 2 and the transparent air intake hose 3. The lower part of the rotating block 6 is fixed with a connecting rod 8, and the toggle block 9 is movably connected between the connecting rods 8. The toggle block 9 has through holes symmetrically opened on the front and rear sides. The through holes on the toggle block 9 are all inclined outward and downward. The connecting rod 8 slides in the through holes on the toggle block 9. The support rod 10 is slidably connected to the first fixed block 4, and the compression spring 11 is fixed between the support rod 10 and the first fixed block 4. The support rod 10 supports the toggle block 9.

[0039] like Figure 1 and Figure 5 As shown, it also includes a second fixed block 12, a push-type airbag 13, a connecting pipe 14, a one-way valve 1401 and an inflation airbag 15. The second fixed block 12 is fixedly connected to the lower right part of the breathing trainer 1, the push-type airbag 13 is fixedly installed on the second fixed block 12, the one-way valve 1401 is connected to the push-type airbag 13, the connecting pipe 14 is clamped on the one-way valve 1401, the connecting pipe 14 is connected to the one-way valve 1401, the inflation airbag 15 is connected to the upper part of the connecting pipe 14, the inflation airbag 15 is sleeved on the sleeved part of the fixed ventilation pipe 2 and the transparent air intake hose 3, and the inflation airbag 15 is located on the inner side of the clamped part of the two clamping blocks 7.

[0040] When a thoracic surgery patient needs to perform cardiopulmonary rehabilitation exercises, the present cardiopulmonary rehabilitation exercise device for thoracic surgery patients can be used to perform breathing exercises. People first press the support rod 10 to the left, so that the support rod 10 moves to the left and disengages from the toggle block 9, and the compression spring 11 is compressed. Then, the toggle block 9 is pressed downward, and the toggle block 9 squeezes the lower part of the rotating block 6 through the through hole and rotates inward to close, so that the upper part of the rotating block 6 rotates outward to open, and then the clamping block 7 rotates open. People separate the transparent air intake hose 3 and the fixed ventilation pipe 2, put a cotton ball of appropriate size in the fixed ventilation pipe 2, and then put the transparent air intake hose 3 on the fixed ventilation pipe 2, pull the toggle block 9 upward, and the toggle block 9 squeezes the lower part of the rotating block 6 through the through hole. The hole squeezes the lower part of the rotating block 6 to rotate outward, so that the upper part of the rotating block 6 rotates inward, and then the clamping block 7 rotates inward to clamp the socket joint of the fixed ventilation pipe 2 and the transparent air intake hose 3, thereby fixing the fixed ventilation pipe 2 and the transparent air intake hose 3 to prevent the fixed ventilation pipe 2 and the transparent air intake hose 3 from separating during exercise, which is beneficial for patients to perform cardiopulmonary rehabilitation exercises stably. After the toggle block 9 moves upward away from the support rod 10, the support rod 10 is released, and the compression spring 11 is reset to make the support rod 10 move outward to support the fixed toggle block 9, thereby fixing the rotating block 6, thereby maintaining the clamping block 7 firmly clamped between the fixed ventilation pipe 2 and the transparent air intake hose 3.

[0041] Subsequently, people repeatedly press the push-type airbag 13, and the gas in the airbag 13 smoothly enters the connecting pipe 14 through the one-way valve 1401. In this way, the push-type airbag 13 can inflate the inflatable airbag 15 through the connecting pipe 14, causing the inflatable airbag 15 to expand. The expansion of the inflatable airbag 15 seals the connection part of the fixed ventilation pipe 2 and the transparent intake hose 3, avoiding air leakage and facilitating the maintenance of the patient's exercise effect. When the inflatable airbag 15 expands to an appropriate degree, people stop pressing the push-type airbag 13, and the one-way valve 1401 prevents the air in the inflatable airbag 15 from flowing back, maintaining the inflated state of the inflatable airbag 15. Subsequently, the patient can perform cardiopulmonary rehabilitation exercises. The patient holds the end of the transparent intake hose 3 and exhales. The patient can observe the rising situation of the indicating ball through the transparent breathing trainer 1. After the exhalation is completed, the transparent intake hose 3 is released and inhalation is performed. After the breathing is balanced, the above breathing actions are repeated. During the patient's breathing training, the cotton ball intercepts the patient's saliva, preventing saliva from entering the interior of the breathing trainer 1, thereby avoiding a large number of bacteria in the interior of the breathing trainer 1 due to saliva, facilitating the patient to perform breathing training safely and hygienically. Moreover, the patient can immediately observe the saliva situation in the transparent intake hose 3. If obvious saliva is found in the transparent intake hose 3, the exercise can be terminated in time, and the saliva in the transparent intake hose 3 can be cleaned in time. In this way, it is beneficial to prevent saliva from entering the interior of the breathing trainer 1. After the exercise is completed, the connection between the connecting pipe 14 and the one-way valve 1401 is disconnected, and the air in the inflatable airbag 15 flows out through the connecting pipe 14, and the inflatable airbag 15 contracts and resets. Subsequently, the clamping block 7 is rotated to open, separating the fixed ventilation pipe 2 and the transparent intake hose 3. The cotton ball is taken away, the transparent intake hose 3 is cleaned, and the connecting pipe 14 and the one-way valve 1401 are snap-connected to reset the clamping block 7.

[0042] Embodiment 2:

[0043] Based on Embodiment 1, as Figure 6 shown, it further includes a cylinder 16 and a rubber push block 17. The cylinder 16 is fixedly installed in the upper part inside the breathing trainer 1. The rubber push block 17 is bolted to the telescopic part of the cylinder 16. The rubber push block 17 is located inside the fixed ventilation pipe 2, and the rubber push block 17 is in contact with the inner wall of the fixed ventilation pipe 2. The rubber push block 17 has little wear on the inner wall of the fixed ventilation pipe 2, and the rubber push block 17 is set in a circular sheet shape.

[0044] When manually removing the cotton ball from the fixed ventilation pipe 2, the cotton thread of the cotton ball may remain inside the fixed ventilation pipe 2. The remaining cotton thread enters the inside of the breathing trainer 1 with the patient's next exhalation, which will affect the use effect of the breathing trainer 1. Therefore, it is necessary to prevent the cotton thread from remaining inside the fixed ventilation pipe 2. The specific operation is as follows: When placing the cotton ball, make the cotton ball located to the right of the rubber push block 17. When separating the fixed ventilation pipe 2 and the transparent intake hose 3 and it is necessary to remove the cotton ball, the patient controls the telescopic part of the cylinder 16 to extend, so that the rubber push block 17 moves to the right. The rubber push block 17 moving to the right can quickly and completely push out the cotton ball, thus preventing the cotton thread of the cotton ball from remaining inside the fixed ventilation pipe 2 and avoiding the cotton thread from affecting the patient's cardiopulmonary rehabilitation exercise effect. After the cotton ball is removed, control the telescopic part of the cylinder 16 to contract, so that the rubber push block 17 moves to the left to reset.

[0045] As Figure 1 , Figure 7 and Figure 8 shown, it also includes a U-shaped connecting block 18 and a fan 19. The U-shaped connecting block 18 is fixedly connected to the transparent intake hose 3, the fan 19 is fixedly installed on the U-shaped connecting block 18, the air outlet part of the fan 19 faces the transparent intake hose 3, and the fan 19 is close to the air inlet of the transparent intake hose 3.

[0046] As Figure 1 and Figure 9 shown, it also includes a third fixing block 20, an electric push rod 21 and a rubber pushing ring 22. The third fixing block 20 is fixedly installed on the upper right side of the breathing trainer 1, the electric push rod 21 is fixedly connected to the third fixing block 20, the rubber pushing ring 22 is bolted to the telescopic part of the electric push rod 21, the rubber pushing ring 22 is sleeved on the transparent intake hose 3, and the rubber pushing ring 22 causes little wear to the outside of the transparent intake hose 3.

[0047] As Figure 1 , Figure 10 and Figure 11 shown, it also includes a pull ring 23 and a filter net 24. The filter net 24 is snap-connected to the part of the transparent intake hose 3 close to the air inlet, and the pull ring 23 is fixedly connected to the filter net 24.

[0048] When the patient exhales into the transparent intake hose 3, compared with the breathing trainer 1 placed in the air, the temperature inside the patient's mouth is higher, and the temperature of the exhaled gas is also higher. The water vapor mixed in the gas liquefies into water droplets when it enters the interior of the breathing trainer 1 and encounters cold. These water droplets adhering to the indicating ball will change the weight of the indicating ball, thus affecting the patient's cardiopulmonary rehabilitation exercise. Therefore, it is necessary to prevent the water vapor mixed in the patient's exhaled gas from liquefying into water droplets on the indicating ball of the breathing trainer 1. The specific operation is as follows: When the patient exhales while holding the transparent intake hose 3, the filter net 24 intercepts the water vapor in the patient's exhaled gas, thereby preventing the water vapor from entering the interior of the breathing trainer 1, and further preventing the water vapor from liquefying into water droplets on the indicating ball, which is beneficial to improving the patient's exercise effect. In addition, the filter net 24 can intercept saliva, which is beneficial to preventing saliva from entering the interior of the breathing trainer 1. Subsequently, people can start the fan 19, and the fan 19 cools the exhaled gas of the patient, causing the water vapor in the gas to liquefy in advance inside the transparent intake hose 3 instead of inside the breathing trainer 1, so as to prevent the water vapor in the gas from liquefying into water droplets and adhering to the indicating ball, which is beneficial to improving the patient's cardiopulmonary rehabilitation exercise effect. Moreover, during the exercise, people can control the telescopic part of the electric push rod 21 to extend, so that the rubber pushing ring 22 moves downward. The downward movement of the rubber pushing ring 22 squeezes the transparent intake hose 3 into a U shape. In this way, the U-shaped part of the transparent intake hose 3 can intercept the water vapor in the patient's exhaled gas, further preventing the water vapor from entering the breathing trainer 1. And the U-shaped part of the transparent intake hose 3 can intercept saliva to a certain extent, which is also beneficial to preventing saliva from entering the interior of the breathing trainer 1. When the exercise is over, control the telescopic part of the electric push rod 21 to contract and reset, turn off the fan 19 and the electric push rod 21, hold the pull ring 23, take out the filter net 24, clean the filter net 24, and after cleaning, snap the filter net 24 into the transparent intake hose 3.

[0049] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
