[0031] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0032] The utility model provides Figs. 1-3 As shown in the figure, a quadriceps contraction exercise reminder is intended to solve the shortcomings of existing quadriceps contraction exercise equipment that lacks feedback devices.

[0033] The quadriceps contraction exercise reminder mainly includes: a patellar sleeve 100, an air bag 200, a sound generator 211, a pressure recorder 321 and a counter.

[0034] The patella sleeve 100 is used for fixing at the joint, and the patella sleeve 100 preferably does not limit the joint bending of the patient, reducing the impact on the flexibility of the joint of the patient. The air bag 200 is arranged on the patella sleeve 100, and the air bag 200 is arranged corresponding to the popliteal fossa. When the patient exercises the quadriceps femoris, the patient needs to force the knee downward, at this time the popliteal fossa of the patient will press the air bag 200. The air bag 200 is provided with an air outlet 210, and the air bag 200 is used to generate air flow in the air outlet 210 under pressure. Specifically, when the air bag 200 is pressed, the gas in the air bag 200 is sprayed out through the air outlet 210. When the pressure on the air bag 200 disappears or decreases to a certain extent, the air bag 200 will rebound to restore its original shape, preparing for the next pressure deformation. The sound generator 211 is detachably arranged in the air outlet 210, and the sound generator 211 is used to generate a prompt sound through the air flow generated in the air outlet 210. Specifically, the structure of the sound generator 211 is the structure of a whistle, which vibrates the air flow in the whistle to produce a whistling sound. The principle of the sound generator 211 and the air bag 200 can refer to the "squeeze to call small yellow duck" or "call shoes" in children's toys. The prompt sound generated by the sound generator 211 replaces the prompt of the family members to the patient, which can improve the self-care ability of the patient and reduce the labor cost.

[0035] The pressure recorder 321 and the counter are arranged on the patella sleeve 100 respectively. The pressure recorder 321 is used to detect whether the air bag 200 is pressed, and the counter is used to count the number of times of pressure on the air bag 200 through the pressure recorder 321. The pressure recorder 321 can have various forms, as long as it can detect whether the air bag 200 is pressed, such as indirectly judging whether the air bag 200 is pressed by detecting the air pressure of the air bag 200, the volume of the air bag 200, the distance between the surfaces of the air bag 200, the air flow of the air outlet 210, whether the sound generator 211 generates a prompt sound, etc. Through the cooperation of the pressure recorder 321 and the counter, the action of the patient during exercise can be counted, so that the exercise is effective and quantifiable.

[0036] In actual use, the patella sleeve 100 is first fixed to the leg of the patient, and the air bag 200 is placed in alignment with the popliteal fossa of the patient, so that the air bag 200 is located between the popliteal fossa of the patient and the bed. When the patient needs to exercise, the patient moves the knee downward to press the air bag 200. The air bag 200 is deformed under pressure and blows out the gas in it through the air outlet 210. When the gas blown out of the air outlet 210 passes through the sound generator 211, vibration is generated to produce a sound that the patient can hear, which serves as a prompt for the patient to perform the action correctly. Specifically, the length of the air bag 200 between the popliteal fossa of the patient and the bed can be adjusted so that the patient can hear a suitable sound when the action is correct.

[0037] Postoperative rehabilitation is an important part of hip and knee arthroplasty, and patients usually start rehabilitation training soon after surgery, mainly through quadriceps muscle exercise to promote muscle strength recovery. The patients of hip and knee arthroplasty are mainly the elderly, and the quadriceps muscle contraction exercise needs to force the knee downward, but it is difficult for the elderly to complete it regularly, and the family members need to put their hands under the patient's knee to feel whether the patient is forcing downward, so as to ensure the effectiveness of quadriceps muscle exercise, but this operation needs to be accompanied by family members, which is more labor-intensive, and manual recording of exercise times is prone to errors.

[0038] The utility model discloses a knee cap 100 is set up on the leg to fix the air bag 200 on the popliteal fossa of patient, when the patient carries out quadriceps muscle exercise, forces the knee downward to pressurize the air bag 200, the air bag 200 contracts and sends the prompt sound through the sounder 211, thereby realizing the effect that the patient is informed whether the action is qualified without the accompaniment of family members, and the air bag 200 is counted by the counter to judge the number of patient's exercise, which is convenient for medical staff to judge the effectiveness of quadriceps muscle exercise, promotes patient recovery, improves patient's self-care ability, and reduces labor cost.

[0039] In some embodiments, as shown in Figs. 1-3 The knee cap 100 includes a first mounting plate 110 and a plurality of fixing belts 120.

[0040] The first mounting plate 110 is arranged corresponding to the popliteal fossa, and the air bag 200 is arranged on the surface of the first mounting plate 110 away from the leg. The plurality of fixing belts 120 are connected with the mounting plate to form a plurality of ring structures, and the plurality of ring structures are used to be sleeved on the leg.

[0041] Specifically, the first mounting plate 110 can be stably fixed on the leg of the patient by the plurality of fixing belts 120. Since the joints of the patient can be bent, a part of the fixing belts 120 can be fixed to the thigh, and the other part of the fixing belts 120 can be fixed to the calf. When the joint of the patient is bent, the first mounting plate 110 can still be stably fixed on the leg of the patient.

[0042] In some embodiments, as shown in Figs. 2-3 The first mounting plate 110 is folded in half along the joint to form a mounting portion 111 and a pressing portion 112. The air bag 200 is arranged on the mounting portion 111, and the plurality of fixing belts 120 are arranged on the mounting portion 111 and the pressing portion 112.

[0043] Specifically, if the first mounting plate 110 is too hard, the first mounting plate 110 will not bend when the patient bends the joint, which will affect the joint flexibility of the patient and affect the exercise effect. Through the above structure, the mounting portion 111 and the pressing portion 112 are respectively fixed on the thigh and the lower leg of the patient, and the angle between the mounting portion 111 and the pressing portion 112 will change when the patient bends the joint, thereby reducing the influence on the joint flexibility of the patient. Since the air bag 200 is only arranged on the mounting portion 111, the air bag 200 will not be subjected to force when the bending angle of the joint of the patient is normal, so that the sound is not easily emitted or the joint flexibility of the patient is not easily affected when walking normally.

[0044] In some embodiments, as shown in Fig. 3 The patellar sleeve 100 further comprises a second mounting plate 130, which is arranged on the fixing belt 120 and corresponds to the knee.

[0045] The quadriceps muscle contraction exercise prompter further comprises a display 310, which is electrically connected with the counter and is used to display the value recorded by the counter. This facilitates the medical staff or family members to determine the exercise times of the patient.

[0046] In some embodiments, the pressure recorder 321 comprises an airflow sensing switch (not shown in the figure), which is arranged in the air outlet nozzle 210 and is electrically connected with the counter.

[0047] In actual use, the patient moves the knee downward to press the air bag 200, the air bag 200 is deformed under pressure and blows out the gas in the air bag 200 through the air outlet nozzle 210, at which time the airflow sensing switch can detect the airflow to indirectly determine that the state of the air bag 200 has changed.

[0048] In some embodiments, as shown in Fig. 3 The pressure recorder 321 comprises a whistle sound sensor 320, which is arranged on the second mounting plate 130 and is used to identify the prompt sound emitted by the sound emitter 211, and the whistle sound sensor 320 is electrically connected with the counter.

[0049] Specifically, in actual use, the gas blown out by the air outlet nozzle 210 will vibrate when passing through the sound emitter 211 to emit a sound that can be heard by the patient, and the whistle sound sensor 320 can identify the sound emitted by the sound emitter 211.

[0050] In some embodiments, the quadriceps muscle contraction exercise prompter further comprises a vibrator (not shown in the figure), which is arranged on the second mounting plate 130 and is electrically connected with the pressure recorder 321, and is used to feed back whether the air bag 200 is subjected to pressure through the pressure recorder 321.

[0051] Specifically, the hearing of the elderly patient is generally poor, and the prompt sound emitted by the sound emitter 211 can be difficult to hear, and the vibration of the vibrator can better prompt the patient whether the action is in place.

[0052] In some embodiments, as shown in Fig. 3 the quadriceps muscle contraction exercise prompter further comprises: a shell 300 detachably arranged on the second mounting plate 130, the counter, the display 310, the whistle sound sensor 320 and the vibrator are arranged in the shell 300.

[0053] Specifically, since the prompt sound emitted by the sound emitter 211 is transmitted through the air, the sound emitter 211 can emit wireless signals to the whistle sound sensor 320 in one direction without the need for circuit connection, so that multiple electronic components can be detached from the patella sleeve 100 to reduce the weight of the patella sleeve 100 on the patient's leg and reduce the burden on the patient. Preferably, a battery can be provided in the shell 300 to power the multiple electronic components, so that it can be used without connecting the power cord.

[0054] In some embodiments, as shown in Fig. 2 the quadriceps muscle contraction exercise prompter further comprises: a pressure relief valve and a one-way valve 220.

[0055] The air bag 200 is in communication with the sound emitter 211 through the pressure relief valve, and the one-way valve 220 is arranged on the air bag 200, and the one-way valve 220 is used to allow external gas to enter the air bag 200.

[0056] Specifically, the sound emission of the sound emitter 211 is the vibration generated when the gas blown out of the air outlet 210 flows through the sound emitter 211 to emit a sound that the patient can hear, so when the gas flow rate blown out of the air outlet 210 is too low, the sound emitted by the sound emitter 211 is small, so the pressure in the air bag 200 can be increased through the pressure relief valve, and when the pressure in the air bag 200 reaches the preset value, the gas inside is quickly blown out through the air outlet 210, so that a loud sound can be emitted through the sound emitter 211.

[0057] In some embodiments, the pressure relief valve is an adjustable pressure relief valve, which can adjust the preset value of the pressure relief valve according to the actual situation to achieve better prompting effect while reducing the impact on the patient.

[0058] In summary, a quadriceps muscle contraction exercise prompter is provided, which comprises a patella sleeve, a sounder, and an air bag, a pressure recorder and a counter arranged on the patella sleeve respectively, the air bag is arranged corresponding to the popliteal fossa, the air bag is provided with an air outlet, and the sounder is detachably arranged in the air outlet. The air bag is fixed on the popliteal fossa of the patient by arranging the patella sleeve on the leg, when the patient exercises the quadriceps muscle, the knee is forced downward to press the air bag, the air bag emits a prompt sound through the sounder after contraction, thereby achieving the effect that the patient can be informed whether the action is qualified without accompanying family members, and the number of times of pressure of the air bag is counted by the counter to judge the number of times of exercise of the patient, which is convenient for medical staff to judge the effectiveness of the quadriceps muscle exercise, promotes the recovery of the patient, improves the self-care ability of the patient, and reduces the labor cost.

[0059] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. Other different forms of changes or variations can be made on the basis of the above description for those skilled in the art. All the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
