Technical Field

[0001] The invention relates to the field of medical rehabilitation equipment, and in particular to a pedal-type cardiopulmonary function rehabilitation training device. Background Art

[0002] In the early and middle stages of recovery, reasonable aerobic training to improve cardiopulmonary function is a common and effective means of rehabilitation for cardiac surgery patients. However, in actual clinical practice, many times, due to the influence of factors such as the narrow space in the ward, the relative weakness of patients and their limited mobility, slow walking and exercises are often effective but cannot be truly implemented. Moreover, due to the relative boredom, patients are not interested enough and their compliance is poor. In order to truly realize bedside recovery training, as a rehabilitation device, its compact structure, ease of use and economy are particularly important. At present, some simple rehabilitation training equipment used in clinical practice either has poor training effect or is not convenient enough to use. Summary of the invention

[0003] The purpose of the present invention is to provide a pedal-type cardiopulmonary function rehabilitation training device which can be flexibly arranged beside a bed and is easy to use.

[0004] To achieve the above-mentioned invention object, the technical solution adopted by the present invention is: a pedal-type cardiopulmonary function rehabilitation training device, comprising a hollow disc-shaped water storage tray, a center sleeve is arranged on the top of the water storage tray, and a water pushing mechanism for allocating water stored in the water storage tray is arranged inside the water storage tray;

[0005] A mounting bracket is provided on the top of the water storage tray, a transmission mechanism is provided inside the mounting bracket, and the transmission mechanism passes through the center sleeve and is transmission-connected with the water pushing mechanism; a pedal mechanism is provided on the top of the mounting bracket, and the pedal mechanism is transmission-connected with the transmission mechanism;

[0007] The water pushing mechanism comprises a plurality of upper blades and lower blades which are respectively arranged at the lower section of the central rotating sleeve and the lower end of the central rotating shaft.

[0008] Preferably, the upper blade is in an L-shape with the outer end bent downward, and the length of the lower blade matches the length of the horizontal side of the upper blade.

[0021] like Figure 1-4 As shown, a pedal-type cardiopulmonary function rehabilitation training device includes a hollow disc-shaped water storage pan 1 made of transparent plastic. The water storage pan 1 adopts a flat structure and is stable to install. It is not easy to shake during pedaling exercises. The bottom of the water storage pan 1 can be installed in the form of direct placement, or rollers can be added to facilitate movement. The rollers should have brakes for easy fixation, or rubber support feet can be directly set. In order to achieve water replenishment of the water storage pan 1 and drainage after use, the water storage pan 1 is generally provided with a water replenishment port (water inlet) at the top and a drainage port at the bottom, and is adapted to be equipped with a corresponding cover.

[0022] like Figure 1 and 2 As shown in the figure, a center sleeve 2 is provided on the top of the water storage tray 1, and a water pushing mechanism for allocating the water stored in the water storage tray 1 is provided inside the water storage tray 1. The center sleeve 2 is used to pass through the transmission mechanism. Since the transmission mechanism is rotatable, the center sleeve 2 can wrap the transmission parts of the transmission mechanism that have certain dangers for safety reasons. For the sake of clarity, the center sleeve 2 shown in the figure is shorter, and it can be set higher in actual application to achieve effective wrapping protection.

[0023] The water storage pan 1 of the present invention is provided with a mounting bracket 3 at the top. Generally, the mounting bracket 3 includes two vertical plates parallel to each other arranged on both sides of the central sleeve 2, and the tops of the vertical plates are connected by a top plate. A transmission mechanism is provided inside the mounting bracket 3, and the transmission mechanism passes through the central sleeve 2 and is in transmission connection with the water pushing mechanism. A pedal mechanism is provided at the top of the mounting bracket 3, and the pedal mechanism is in transmission connection with the transmission mechanism.

[0024] The pedal mechanism is a component used to drive the transmission mechanism to rotate, such as Figure 1 As shown in , the pedaling mechanism generally includes a rotating wheel 13 between the tops of the two vertical boards on which the mounting bracket 3 is arranged, and the wheel axles at both ends of the rotating wheel 13 extend outside the vertical boards and are fixedly connected to one end of a crank arm 14, and the other end of the crank arm 14 is connected to a pedal 15. The rotating wheel 13 is a worm wheel, and the upper section of the central rotating shaft 4 (a component of the transmission mechanism) is a worm section 16 that matches the worm wheel. This method has a more compact and stable structure and a good transmission effect. Compared with the chain and sprocket method, it is conducive to direct force transmission and has a better exercise effect.

[0025] As one of the core mechanisms of the present invention, combined with Figure 1 and 2 As shown in the figure, the transmission mechanism includes a central rotating shaft 4 and a central rotating sleeve 5 sleeved outside the lower section of the central rotating shaft 4, the upper end of the central rotating shaft 4 is connected to the pedal mechanism, and the lower end extends to the lower part of the water storage tray 1, and is used to connect with the lower blade 10; due to its longer overall length, in order to improve its stability, a stabilizing bearing 17 is provided outside the central rotating shaft 4 below the worm section 16, and the stabilizing bearing 17 is connected to the vertical plate of the mounting bracket 3 through a short support rod.

[0026] The lower end of the central rotating sleeve 5 extends into the upper part of the water storage tray 1, and is used to connect with the upper blade 9. The central rotating shaft 4 and the central rotating sleeve 5 are connected through a reverse transmission assembly, and the reverse transmission assembly includes an upper bevel gear 6 and a lower bevel gear 7 respectively arranged outside the central rotating shaft 4 and the central rotating sleeve 5, and a transition arranged on the inner side wall of the central sleeve 2, and the transition bevel gear 8 is respectively meshed with the upper bevel gear 6 and the lower bevel gear 7.

[0027] Since the upper paddle blade 9 and the lower paddle blade 10 drive the water to move in different directions, there is no inertial influence of the entire water moving in the same direction. When the pedaling speed is fast, it can also ensure that the water produces sufficient resistance to the upper paddle blade 9 and the descending blade 10. At the same time, since the influence of the inertial motion of the water is eliminated, the pedaling mechanism can be prevented from idling under the reaction, avoiding harm to the patient.

[0028] On this basis, in order to further improve the use effect of the present invention, a better way can also be that the upper blade 9 is L-shaped with the outer end bent downward, and the length of the lower blade 10 matches the length of the horizontal side of the upper blade 9. In this way, in addition to realizing the upper and lower layer water diversion, the inner and outer layer water diversion can also be realized, so that the resistance of the entire water body to the blade is more stable overall. In addition, if Figure 4 As shown in the figure, it is further possible to provide a plurality of flow holes 11 extending along the length direction of the upper blade 9 and the lower blade 10 on both the upper blade 9 and the lower blade 10, and both the upper blade 9 and the lower blade 10 located at the rear side of the flow hole 11 in the rotation direction are provided with an extension plate 12, the extension plate 12 on the upper blade 9 extends obliquely downward, and the extension plate 12 on the lower blade 10 extends obliquely upward. Through the warm flow of the flow hole 11 and the counter-flow guidance of the extension plate 12, the consistency of the water flow direction caused by the directional rotation of the blades within the range is eliminated again, and the effectiveness of the resistance is ensured.

[0029] Since different patients have different recovery exercise requirements, in order to meet different needs. A resistance adjustment tube 18 is also provided on the top plate of the mounting bracket 3, and a rubber resistance plug 19 is provided in the lower section of the resistance adjustment tube 18, and the rubber resistance plug 19 is connected to the central rotating shaft 4, and a through hole is provided in the center of the upper end. The resistance adjustment tube 18 is externally threaded and connected with a resistance cap 20, and a friction rod 21 matching the through hole is provided on the inner side of the resistance cap 20, and the friction rod 21 extends into the through hole of the rubber resistance plug 19. By rotating the resistance cap 20, the friction rod 21 can be driven to move up and down, and then by changing the length of the friction rod 21 in the through hole of the rubber resistance plug 19, the friction force between the two is changed, and then the rotation resistance of the central rotating shaft 4 is changed to adapt to different patients.
