Description

Pelvis fracture rehabilitation training device

Technical Field

The invention belongs to the field of fracture rehabilitation training, and particularly relates to a pelvis fracture rehabilitation training device.

Background

Pelvic fractures are a serious injury, often requiring surgical repair. Before and after surgery, patients need to perform systematic rehabilitation training to restore normal activity and quality of life. Preoperative pre-training is particularly important for patients with pelvic fractures. Through preoperative pre-training, the flexibility and the activity range of joints can be improved, the strength and the endurance of muscles are enhanced, and the blood circulation is promoted, so that the risks of postoperative joint stiffness, muscle atrophy and thrombosis are reduced, and the postoperative rehabilitation training can help patients to recover normal activity.

In order to achieve the best results of preoperative pre-training and postoperative rehabilitation training, patients often need to be effectively trained by means of some training device. However, the existing training devices have some disadvantages:

In the prior art, many rehabilitation devices can only perform a single type of training, which limits the overall rehabilitation effect of a patient in preoperative rehabilitation and postoperative rehabilitation, and cannot improve joint mobility, muscle strength and endurance at the same time. In addition, many existing rehabilitation training devices lack adaptability to patients of different sizes, and cannot be adjusted according to the sizes of the patients, resulting in insufficient comfort and effectiveness during training. And most of the existing rehabilitation devices need manual adjustment, are complex to operate and are inconvenient for medical staff to adjust.

Example 3

The operating principle of the invention is as follows:

The patient of pelvis fracture needs to use the device for pre-training before doing the operation, reduces the postoperative joint stiffness and the movement limitation by increasing the flexibility of the joint, increases the elasticity of the muscle, and reduces the postoperative muscle tension and pain.

The medical personnel first stretches the length of the first swivel plate 25 and the first swivel plate 24 according to the patient's stature to adapt the device to the patient's stature. The number of small pads 41 is then selected according to the stretched lengths of the connecting plate 21 and the first and second swivel plates 24, 25, and all small pads 41 are spliced together to form a mattress 4 of suitable length. After the mattress 4 is laid, the medical staff guides the patient to lie on the device. The ankle pump mechanism 33 is then moved and the length between the movable foot rest 336 and the fixed foot rest 334 is adjusted according to the size of the patient's foot to fit the patient's sole to the ankle pump mechanism 33. The foot is then secured with securing strap 337.

The medical staff selects the required functional mode through the key module of the controller 5 and performs timing operation. Then, the motor 333 receives the electric signal from the cpu, and drives the turning block 332 to repeatedly bend and extend the ankle joint of the whole ankle pump mechanism 33, and the rotation angle of the ankle pump mechanism 33 is between 0 ° and 60 °. The alarm sounds an alarm after the timing is finished, alerting completion of the flexion and extension movements of the ankle joint, and then the patient's foot is disengaged from the ankle pump mechanism 33.

The medical staff then rotates the limiting frame 342 of the leg lifting mechanism, so that the limiting frame 342 is parallel to the fourth sliding rail 252, and then the leg lifting mechanism 34 moves towards the foot of the patient, and the purpose of the rotation is to prevent collision with the ankle pump mechanism 33 in the moving process of the limiting frame 342. After the leg rest 34 is moved to the patient's foot position, the limit frame 342 is pivoted. The patient can put both feet on the both side support bars 343 or put both side support bars 343 along the limit frame 342, and the patient can put both feet on both side support bars 343. The medical staff can then select the required functional mode through the key module of the controller 5 and perform timing operation. The fourth electric push rod 342 is started after being transmitted by the central processing unit, and the lifting action of the fourth electric push rod 342 enables a patient to perform leg lifting training, straightens knee joints as much as possible and then lifts the straight legs to the position, where the heel is 15cm away from the bed. After the timing is finished, the alarm gives an alarm, the feet of the patient are separated from the leg lifting mechanism 34, and leg lifting training is completed.

Patients also need to strengthen the upper limb training. The patient lies on his/her back or his/her knees remain bent, and the support stand 311 is moved to the chest position of the patient. After holding the barbell 32 with both hands, the patient slowly lifts up and then slowly puts down the barbell, and makes 2 to 3 groups of barbells each for about 5 times. After the upper limb training is completed, the support frame 322 is moved to the outermost end.

After the support frame 322 is moved to the outermost end, the guard selects a desired functional mode through the key module of the controller 5. The first electric push rod 26 is started after being subjected to signals transmitted by the central processing unit, the telescopic rod of the first electric push rod 26 pushes the rotating frame 22 at the front end of the connecting plate 21, the rotating frame 22 rotates, and the rotating frame 22 drives the first rotating plate 24 to rotate upwards to form a backrest. Then, the second electric push rod 27 is started after being transmitted by the central processing unit, the telescopic rod of the second electric push rod 27 pushes the rotary rod 254 to rotate, the rotary shaft of the rotary frame 22 connected with the rotary rod 254 also rotates, and the rotary frame 22 and the second rotary plate 25 rotate downwards.

The patient sits on the connecting plate 21, the two lower legs are suspended outside the connecting plate 21, the ankle takes sandbags, rubber bands and the like as loads, the ankle is kicked to a knee straightening position, slowly falls down for 20-30 times/group, has a rest for 30 seconds between groups, has 4-6 groups/group and has 2-3 groups/day.

The above is the pre-rehabilitation training of the patient with the pelvic fracture before the operation. After the operation is finished, the patient can also perform postoperative rehabilitation training on the device in the later period.
