Description

Technical Field

[0001] The utility model relates to a rehabilitation device, in particular to a post-operative straightening rehabilitation device for knee joints. Background Art

[0002] After knee surgery, patients need to keep their knees bent for a while to prevent cracking of the surgical site due to straightening and stretching of the knees. However, it is inconvenient for patients to straighten their knees while sitting on the bed. At the same time, the patient is in a state of waiting for recovery, and the knee joint is still swollen and painful and cannot be fully straightened. In response to this phenomenon, due to the lack of special rehabilitation facilities, the current measures taken are to use ice compresses to relieve swelling and pain, and the patient or the caregiver assists in pressing and straightening the knee joint with their hands for rehabilitation. Although the above method plays a certain role in rehabilitation assistance, it is not very convenient to operate. Therefore, it is necessary to develop a device specifically for straightening and rehabilitation of patients' knee joints after surgery. Summary of the invention

[0003] In view of the above situation, the utility model provides a postoperative straightening rehabilitation device for the knee joint, which effectively solves the rehabilitation problem of cold compress and weight-bearing correction and straightening.

[0004] The technical solution of the utility model is: a postoperative straightening rehabilitation device for knee joints, comprising:

[0005] A bag having two spaced air chambers, a connecting body after enclosing, and an air pump for inflating the bag;

[0006] There is at least one sand bag and a spare bag, and ice cubes can be put into the spare bag to form an ice bag; the sand bag and the ice bag can be wrapped by the surrounding bag.

[0007] In the present invention, the two air chambers are independently arranged or connected through an air path; and an air filling and discharging nozzle is arranged on the air chamber.

[0008] In the present invention, the air pump is a manual air bag or a foot-operated air pump, which is connected to the air filling and discharging nozzle on the air chamber through an air pipe.

[0009] In the present invention, hook and loop fasteners are arranged on the two air chambers, the sandbag and the spare bag, so that the sandbag and the spare bag can be bonded to the two air chambers.

[0010] In the present invention, the connector is a Velcro fastener or a zipper.

[0011] In the present invention, the spare bag is provided with a waterproof lining layer, which is a plastic film or a rubber coating layer.

[0012] The utility model has the beneficial effect of: through the specially designed airbag type knee joint postoperative straightening rehabilitation device, the ice pack and the non-inflated air bag are combined to surround the patient's postoperative knee joint healing area to physically cool down and relieve pain.

[0013] The sandbag and the surrounding bag are combined and placed around the patient's knee joint after surgery. The air chamber of the surrounding bag is filled with gas to form an inflatable airbag that combines with the sandbag to generate static pressure, which has a good rehabilitation effect on the straightening rehabilitation of the knee joint. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the a, b, and c parts of the present invention;

[0015] Figure 2 yes Figure 1 Reference picture of the surrounding bag after inflation and surrounding the sandbag. DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] As shown in FIG. 1, a postoperative straightening rehabilitation device for knee joint includes a bag A formed of two spaced first air chambers 1 and second air chambers 2. The bag A is provided with a connector after enclosing. The connector described in this embodiment is a hook and loop 3 provided at both ends of the bag A, which is enclosed and fixed by the hook and loop 3 at both ends. In the above, the first air chamber 1 and the second air chamber 2 are connected to each other through an air path 4, and a gas filling and discharging nozzle 5 is provided on the first air chamber 1, which is connected to an air pump 6 through the gas filling and discharging nozzle 5 (see a in the figure). The air pump 6 in the above is a manual inflatable bag. The first air chamber 1 and the second air chamber 2 on the bag A can be inflated and expanded by the air pump 6. In this embodiment, a sandbag 7 (see b in the figure) and a spare bag 8 (see c in the figure) are used. The spare bag 8 can be filled with ice cubes to form an ice bag. In order to prevent the ice bag from being permeable, a waterproof lining layer (not shown in the figure) can be provided on the spare bag 8. The waterproof lining layer of this embodiment adopts a composite plastic film. When physically cooling and relieving pain at the healing part of the patient's knee joint after surgery, an ice bag is placed at the healing part of the patient's knee joint, and the bag A is taken out. After the ice bag and the patient's knee joint are wrapped together, they are fixed by the Velcro 3 at both ends of the bag A, and physical cooling and pain relief can be provided. If the first air chamber 1 and the second air chamber 2 need to cooperate, the air bag is inflated by the manual inflatable bag, and the inflated air bag generates static pressure, which plays an auxiliary role in the patient's knee joint extension rehabilitation. Similarly, when the patient's knee joint needs to be straightened and rehabilitated separately, the sandbag 7 is placed at the healing part of the patient's knee joint, and the bag A is taken out. After the sandbag 7 and the patient's knee joint are wrapped together, they are fixed by the Velcro 3 at both ends of the bag A, and the first air chamber 1 and the second air chamber 2 are inflated and expanded by the manual inflatable bag connected to the inflation nozzle 5, and the sandbag 7 is used to apply a common static pressure to the patient's knee joint, accelerating the rehabilitation effect of the patient's knee joint extension.

[0018] In the above, except that the first air chamber 1 and the second air chamber 2 are connected through the air path 4, the first air chamber 1 and the second air chamber 2 can be independently arranged, and the inflation and deflation nozzles 5 are respectively arranged on the two independent first air chambers 1 and the second air chambers 2.

[0019] In the above, according to the need, Velcro can be provided on the first air chamber 1, the second air chamber 2, the sandbag 7 and the spare bag 8. In this way, the sandbag 7 and the spare bag 8 can be bonded to the first air chamber 1 and the second air chamber 2 (not shown in the figure).

[0020] In the above, in addition to the air pump 6 adopting a manual inflatable bag, a foot-operated air pump can be selected to connect the inflating and discharging nozzles 5 on the first air chamber 1 and the second air chamber 2 to inflate.

[0021] In the above, except that the connecting body is selected as the hook and loop fastener 3, it can be a zipper, and its functions are the same.

[0022] In the above, except that the waterproof lining layer in the spare bag 8 is made of a composite plastic film, the waterproof lining layer can be made of a rubber coating layer.

[0023] See Figure 2 A reference diagram of the state of the surrounding bag A and the sandbag 7 after being inflated is given. The sandbag 7 is placed on the second air chamber 2 of the surrounding bag A, and then the first air chamber 1 of the surrounding bag A is surrounded, and the surrounding bag A is fixed to each other through the hook and loop fasteners 3 at both ends of the surrounding bag A. Finally, the manual airbag-type air pump 6 is connected to the inflation nozzle 5 through the air pipe, and the air pump 6 is continuously pressed to the required inflation amount, and the inflation is stopped. When it is necessary to discharge the air, the inflation nozzle 5 switch is turned on to automatically deflate.

[0024] When applied to patients, the method is the same as above.
