Description

Technical Field

[0001] The utility model belongs to the technical field of sports rehabilitation equipment, and particularly relates to a quadriceps femoris exerciser capable of counting. Background Art

[0002] For the quadriceps femoris training of bedridden patients, the training purpose is achieved by relying on the verbal instruction of the patient's own quadriceps femoris muscle in the thigh to exert force / relax. This method depends on the patient's understanding ability to do, which is not intuitive enough. In addition, the patient can be taught to place a cylindrical object under the knee joint and press down the knee to achieve the purpose of quadriceps femoris training. The problem with this method is that it is impossible to quantitatively record and judge the exercise intensity of the patient. Therefore, how to develop a new-structured quadriceps femoris exerciser capable of counting, which can overcome the above problems existing in the prior art, is the direction that those skilled in the art need to further study. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a quadriceps femoris exerciser capable of counting, which can quantitatively record and judge the exercise intensity of patients during the quadriceps femoris training of bedridden patients, and improve the training effect of the quadriceps femoris.

[0004] The utility model discloses a quadriceps femoris exerciser capable of counting, which comprises:

[0005] A leg pad, a cavity is arranged inside the leg pad, and an extending guide groove leading to the cavity is arranged on the upper surface of the leg pad;

[0006] An elastic pressing rod, the lower end of the rod body of the elastic pressing rod is fixedly installed inside the cavity, and the upper end of the rod body of the elastic pressing rod extends out of the upper surface of the leg pad through the extending guide groove;

[0007] A pressure sensor, the pressure sensor is connected with the lower end of the rod body of the elastic pressing rod and is used for reading the pressure value borne by the elastic pressing rod;

[0008] A comparison counter, the comparison counter is signal-connected with the pressure sensor and is used for performing cumulative counting when the pressure value is greater than a preset threshold value and forming a count value;

[0009] A display panel, the display panel is signal-connected with the comparison counter and is used for displaying the count value.

[0010] By adopting this technical solution: during the process of quadriceps femoris training, place the patient's leg on the leg pad, and let the popliteal fossa on the dorsal side of the knee joint abut against the upper end of the rod body of the elastic pressing rod, and squeeze the elastic pressing rod downward along the extending groove when the quadriceps femoris exerts force. At this time, the pressure sensor obtains the pressure value generated by the downward pressure of the human popliteal fossa on the elastic pressing rod. The comparison counter generates a count value when the pressure value reaches the preset value, and the display panel displays the generated count value. Thus, during the quadriceps femoris training of bedridden patients, the exercise intensity of the patients is quantitatively recorded and judged, improving the training effect of the quadriceps femoris.

[0011] Preferably, it further includes: an arc-shaped pad, one end of the arc-shaped pad is fixedly connected to one end of the leg pad as a whole; the upper surface of the arc-shaped pad is an arc surface, and the higher side of the arc surface is located near the leg pad, and the lower side of the arc surface is located away from the leg pad.

[0012] By adopting this technical solution: during the process of quadriceps femoris exercise, let the patient's buttocks rest on the arc-shaped pad, so that the height of the patient's back is lower than the height of the legs during the exercise, improving the exercise effect.

[0013] Preferably, it further includes: an extension pad, one end of the extension pad is detachably fixedly connected to the other end of the leg pad as a whole.

[0014] By adopting this technical solution: for patients with longer legs, the extension pad is used to support their legs during the exercise to avoid the discomfort caused by the legs hanging in the air, making this device applicable to patients of different body types.

[0015] Preferably, the other end of the leg pad is provided with a hook surface of Velcro, and one end of the extension pad is provided with a loop surface of Velcro that matches the hook surface of Velcro.

[0016] By adopting this technical solution: utilize the adhesion cooperation of the hook surface and the loop surface of Velcro to facilitate the splicing and disassembly of the leg pad and the extension pad.

[0017] Preferably, the elastic pressing rod includes a spring column and a silica gel ball. The lower end of the spring column is located in the cavity, and the upper end of the spring column passes through the extending groove and extends out of the upper surface of the leg pad and is fixedly connected to the silica gel ball as a whole; the inner diameter of the extending groove is configured to be 2-3 mm larger than the outer diameter of the column body of the spring column.

[0018] By adopting this technical solution: The silica gel ball has a certain elasticity, avoiding the pain in the popliteal fossa during exercise. During exercise, when the quadriceps femoris exerts force, the popliteal fossa squeezes the silica gel ball downward along the protruding guide groove. At this time, the spring column is compressed, and when the popliteal fossa releases the silica gel ball, the spring column automatically resets. By setting the inner diameter of the protruding guide groove to be 2 - 3 mm larger than the outer diameter of the column body of the spring column, the situation of the column body bending during the compression of the spring column can be reduced, improving the accuracy of the pressure sensor reading.

[0019] Preferably, the display panel adopts an LED display screen, and the LED display screen is fixedly installed on the side wall of the leg pad.

[0020] Compared with the prior art, the present utility model has made the following technical progress:

[0021] First, the present utility model can quantitatively record and judge the exercise intensity of patients during the quadriceps femoris training of bedridden patients, improving the training effect of the quadriceps femoris.

[0022] Secondly, during the process of quadriceps femoris exercise, the present utility model can make the patient keep the back height lower than the leg height during exercise, improving the exercise effect.

[0023] Thirdly, for patients with longer legs, during exercise, the extension pad is used to support their legs, avoiding the discomfort caused by the legs hanging in the air, making the device applicable to patients of different body types.

[0024] Finally, the device structure of the present utility model is simple and suitable for mass production and preparation. Description of the Drawings
