Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to an exercise cardiopulmonary test device. Background Art

[0002] Exercise cardiopulmonary testing measures metabolic and ventilatory indicators such as oxygen uptake and carbon dioxide excretion, as well as electrocardiographic changes, under a certain load to reflect changes in cellular respiratory function. Exercise cardiopulmonary testing emphasizes the interaction between cardiopulmonary function and gas exchange during exercise. It is a comprehensive assessment of the heart and lungs, emphasizing the coupling of external and cellular respiration, that is, the connection between the cardiopulmonary active muscle groups, and particularly emphasizes the combined measurement of cardiopulmonary function. In the presence of lung disease, abnormal cardiopulmonary coupling leads to decreased oxygen transport capacity and the premature onset of anaerobic exercise, resulting in abnormal energy metabolism, lung function, and heart function during exercise. Therefore, exercise cardiopulmonary testing can provide a basis for the comprehensive evaluation of cardiopulmonary function in patients with lung disease, the differential diagnosis of dyspnea, the early diagnosis of respiratory diseases, and the selection of surgical indications.

[0003] In the prior art, common exercise cardiopulmonary testing devices mainly include a power bike, a gas metabolism tester, and an auxiliary computer. Among them, the gas metabolism tester is connected to a breathing mask through a rubber hose, the power bike is fixed to the ground next to the gas metabolism tester by screws, and the body of the power bike is installed with a seat, footrests, and armrests. During the actual exercise cardiopulmonary test, the person being tested wears a breathing mask and sits on the seat of the power bike, holds the armrests with both hands, and places his feet on the two footrests respectively. The person being tested can drive the footrests to rotate for a period of time with his feet. The gas metabolism tester can monitor the cardiopulmonary function of the person being tested during exercise, and the auxiliary computer can display it. Medical staff can use the auxiliary computer to evaluate the cardiopulmonary function of the person being tested during exercise.

[0004] However, the existing cardiopulmonary exercise testing device can only be used to test the subject under a single load condition, and the load cannot be adjusted according to the physical fitness of different subjects. The applicable population is limited, and there is room for improvement. Utility Model Content

[0005] In order to meet different load requirements and improve the usability of an exercise cardiopulmonary testing device, the present application provides an exercise cardiopulmonary testing device.

[0006] The present application provides an exercise cardiopulmonary test device that adopts the following technical solutions:

[0007] An exercise cardiopulmonary test device includes pedals rotatably mounted on both sides of a power bike, each pedal including a pedal, a placement box fixedly mounted at the bottom of each pedal, a load adjustment box slidably mounted within the placement box, and a plurality of weight blocks detachably mounted within the load adjustment box;

[0008] A positioning mechanism is fixedly installed in the load adjustment box, and a plurality of weight-increasing blocks are tightly installed between the inner wall of the placement box and the positioning mechanism;

[0009] A driving module for driving the load adjustment box to slide into or out of the placement box is fixedly installed in the placement box.

[0010] By adopting the above technical solution, during the exercise cardiopulmonary test of the subject, medical personnel can determine the load on the pedals based on factors such as the subject's physical fitness and gender. When adjusting the load on the pedals, medical personnel can use the drive module to drive the load adjustment box to slide out of the placement box. By increasing or decreasing the number of weight blocks, the load on the pedals can be adjusted to meet the testing requirements of different loads and improve the usability of the exercise cardiopulmonary test device. The positioning mechanism within the load adjustment box can be used to position the weight blocks within the load adjustment box, reducing the possibility of the weight blocks loosening when the subject uses the sole of the foot to drive the pedals during the test.

[0024] By adopting the above technical solution, the servo motor can be controlled by the first button and the second button to drive the transmission gear to rotate in different directions. Since the transmission gear is engaged with the transmission rack and the transmission gear is fixed to the bottom of the load adjustment box, the load adjustment box can be driven to slide in or out of the installation cavity, which is convenient for medical personnel to adjust the number of weight blocks in the load adjustment box.

[0025] Preferably, the load adjustment box is fixedly connected to a first baffle at one end away from the positioning screw, and a groove adapted to the first baffle is provided on the side wall of the placement box. The entrance of the installation cavity is located at the bottom of the groove, and the first baffle covers the outside of the joint between the load adjustment box and the installation cavity.

By increasing or decreasing the number of weight blocks 5, the load on pedal 2 can be adjusted to meet the testing requirements of different loads and improve the usability of the cardiopulmonary exercise test device. The positioning mechanism 6 within the load adjustment box 4 can be used to position the weight blocks 5 within the load adjustment box 4, reducing the possibility of weight blocks 5 becoming loose when the subject uses the sole of the foot to drive the pedal 1 to rotate during the test.

[0041] It should be noted that the weight-increasing block 5 used in the embodiment of the present application is an iron block. The material of the weight-increasing block can be changed according to the weight-increasing requirements and is not limited here.

[0042] Reference Figure 2 and Figure 3 An installation cavity 31 adapted to the load regulating box 4 is opened in the placement box 3, and the load regulating box 4 is slidably installed in the installation cavity 31; limiting protrusions 41 are respectively formed on both sides of the load regulating box 4, and limiting grooves 32 adapted to the limiting protrusions 41 are respectively opened on the two opposite inner side walls of the installation cavity 31.
