Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a wrist joint activity trainer. Background Art

[0002] There are many methods of wrist joint training, such as passive movement or active movement. The rehabilitation therapist fixes the distal forearm near the wrist joint with the upper hand, and holds the fingers at the distal end of the wrist joint with the lower hand to perform wrist flexion and extension, radial and ulnar lateral flexion and rotation and other exercises. During exercise, the patient's wrist and fingers should be fully relaxed.

[0003] There are many devices for wrist joint activity training. For example, the utility model patent with announcement number CN201426826Y discloses a wrist joint flexion and extension trainer, and the utility model patent with announcement number CN205434031U discloses a medical wrist joint directional activity brace... However, most of these wrist joint training devices can only perform passive activity training on the wrist joint of one hand at a time. When passive activity training is required for both hands, only the two wrist joints can be trained one by one, which is inefficient. Utility Model Content

[0004] Aiming at the problem that wrist joint training devices in the prior art are inefficient when used by patients who need to perform activity training on the wrist joints of both hands, the utility model provides a wrist joint activity trainer.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A wrist joint activity trainer comprises a left wrist joint training mechanism and a right wrist joint training mechanism arranged on a supporting mechanism, the right wrist joint training mechanism comprises a base, a first rotating mechanism is arranged on the base, a second rotating mechanism is arranged on the first rotating mechanism, a palm model is arranged on the second rotating mechanism, a palm fixing mechanism is arranged on the palm model, the left wrist joint training mechanism has the same structure as the right wrist shutdown training mechanism, and the palm model of the right wrist shutdown training mechanism is a left palm model, and the palm model of the left wrist shutdown training mechanism is a right palm model.

[0007] After adopting this technical solution, when using it, the patient connects both hands to the two palm models respectively. For patients with self-control, they can hold the palm models with both hands, and for patients who cannot control themselves, the palms can be fixed on the palm models through the palm fixing mechanism. It is applicable to both patients with self-control and patients without self-control, and then the patient's wrist joints can be driven to move through the first rotating mechanism and the second rotating mechanism. The patient's wrist joint activity training can be performed on both hands at the same time, which improves the training efficiency.

[0008] Preferably, the supporting mechanism is a table body, the left wrist joint training mechanism and the right wrist joint training mechanism are arranged on the table top of the table body, the lower part of the table body is provided with a first foot pedal and a second foot pedal, and the on and off switches of the left wrist joint training mechanism and the right wrist joint training mechanism are respectively arranged on the first foot pedal and the second foot pedal.

[0009] After adopting this technical solution, when the patient feels very painful or unwell during training and wants to stop training, and at the same time fixes his palms on the palm model through the palm fixing mechanism, the switch cannot be turned off because both hands are training, and it is impossible for someone to watch over the patient at all times. Therefore, in order to avoid the patient having no way to stop the training by himself in this situation, the off switch is set; the on and off switches of the left wrist joint training mechanism and the right wrist joint training mechanism are respectively set on the first foot pedal and the second foot pedal, which is convenient for the patient to turn off.

[0010] Preferably, the supporting mechanism is further provided with a placement seat for placing the arm, and the placement seat is provided with a placement groove.

[0011] After adopting this technical solution, the arm is placed so that the arm and the height adapt to the height of the left wrist joint training mechanism and the right wrist joint training mechanism.

[0012] Preferably, the first rotating mechanism is a left-right rotating mechanism, and the second rotating mechanism is a front-back rotating mechanism.

[0013] Preferably, the left and right rotating mechanism includes a first outer rod fixedly connected to the base, a first rotating groove is provided on the first outer rod, a first inner rod is rotatably connected in the first rotating groove, a first driving motor is also provided on the first outer rod, and an output end of the first driving motor is connected to the first inner rod, and the front and rear rotating mechanism includes a second outer rod arranged perpendicular to the first inner rod, the first inner rod is fixedly connected to the second outer rod, a second rotating groove is provided on the second outer rod, a second inner rod is rotatably connected in the second rotating groove, a second driving motor is provided on the second outer rod, and an output end of the second driving motor is connected to the second inner rod.

[0014] Preferably, the palm model comprises a hard part and a silicone layer wrapped on the hard part, and the hard part is connected to the second rotating mechanism.

[0015] Preferably, the fixing mechanism comprises a fixing strap arranged on each finger of the palm model, one end of the fixing strap is fixedly connected to the finger, and the other end is detachably connected to the finger via Velcro.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. When using the device, the patient connects both hands to the two palm models respectively. For patients with self-control, they can hold the palm models with both hands. For patients who cannot control themselves, they can fix their palms on the palm models through the palm fixing mechanism. This is applicable to both patients with self-control and those without self-control. Then, the patient's wrist joints can be driven to move through the first rotating mechanism and the second rotating mechanism. The patient's wrist joint activity training can be performed on both hands at the same time, which improves the training efficiency.

[0018] 2. Set the closing switch: The on / off switches of the left wrist joint training mechanism and the right wrist joint training mechanism are respectively set on the first foot pedal and the second foot pedal, so that the patient can turn it off easily. BRIEF DESCRIPTION OF THE DRAWINGS
