Description

A lower limb stretching exerciser

Technical Field

The present application relates to the technical field of medical appliances, and in particular to a lower limb stretching exerciser.

Background technique

As we all know, the lower limb stretching exerciser is one of the indispensable tools for hospital care. It is suitable for patients who have undergone lower limb orthopedic surgery. After a period of bed recuperation, patients need to exercise the muscles and bones of the lower limbs through exercise to accelerate the recovery of lower limb motor ability after surgery. All of these require the help of the lower limb stretching exerciser.

At present, in the relevant technology, after searching, the utility model with patent publication number CN206483064U discloses a lower limb auxiliary exerciser, including a front support tube, a rear support tube, an armrest tube, a horizontal connecting tube, a mesh stretching tube, a mesh storage tube, a telescopic mesh, a fixed ring, a movable clamp, a longitudinal connecting tube, a backrest plate, a soft cushion and a weight basket. The front support tube and the rear support tube are connected with a horizontal connecting tube and a mesh stretching tube, and a mesh storage tube is provided above one of the mesh stretching tubes.

Regarding the above-mentioned related technologies, although the existing devices can place drinking water, medicines and other items required by patients during the exercise process by setting a weight basket on the outer side of the backrest board, and can provide different weights for patients in different recuperation stages to achieve the best exercise effect, the applicant has found that after patients with leg injuries have been bedridden for a period of time, their legs have not been active for a long time, which leads to muscle weakness in the patients' legs. Therefore, it is difficult for patients to directly rely on lower limb auxiliary exercisers for walking rehabilitation exercises, and manual assistance is required to help patients use the lower limb auxiliary exercisers for rehabilitation training, which increases the workload and labor intensity of the accompanying personnel. Secondly, it is difficult for the existing devices to perform appropriate and simple traction on the patients' legs, and the practicality is insufficient.

Therefore, we propose a lower limb stretching exerciser which can perform simple rehabilitation training on the patient's legs, so that the patient's legs can gradually recover strength.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The present application is further described in detail below in conjunction with the accompanying drawings.

Referring to FIGS. 1 to 4 , in an embodiment of the present invention, a lower limb stretching exerciser includes:

A base 1, wherein a mounting groove and a connection groove are respectively opened in the base 1;

The support plate 2 is fixedly installed in the installation groove through the connecting shaft 3;

A connecting plate 4, wherein the connecting plate 4 is rotatably disposed in the connecting groove through a connecting rod 5;

Two connecting buckles 6, the two connecting buckles 6 are respectively fixedly welded on the base 1 and the connecting plate 4, and a composite spring 7 is fixedly connected between the two connecting buckles 6;

Two mounting frames 8, both of which are arranged at one end of the connecting plate 4, and a positioning rod 9 is arranged inside the mounting frames 8;

The supporting assembly is arranged at the bottom of the base 1 and is used to place the base 1 in a use position.

When the lower limb stretching exerciser is in use, a support component can be set up, and under the action of the support component, the base 1 can be stably placed in the use position. When it is necessary to perform lower limb rehabilitation training on patients with lower limb injuries, the patient is first allowed to sit on the base 1 and lean on the support plate 2, and then the legs are fixed and limited on the connecting plate 4 through the cooperation of the mounting frame 8 and the positioning rod 9, and then the patient's legs are gradually exerted. The patient's legs will drive the connecting plate 4, which is rotatably connected to the base 1 through the connecting rod 5, to rotate. At the same time, through the cooperation of the connecting buckle 6 and the composite spring 7, the connecting plate 4 has a certain resistance when rotating. On the one hand, it can exercise the patient's lower limb strength, and on the other hand, it can perform appropriate and simple traction on the patient's legs.

In Figures 1-3: the support assembly includes four electro-hydraulic push rods 10, the output ends of the four electro-hydraulic push rods 10 are fixedly welded to the bottom of the base 1, and a support seat 11 is provided at the bottom of the electro-hydraulic push rods 10, and the bottoms of the multiple support seats 11 are fixedly connected with anti-slip rubber pads 12.

The lower limb stretching exerciser, through the arrangement of this structure, can stably place the base 1 in the use position under the cooperation of the support seat 11 and the electro-hydraulic push rod 10. At the same time, when the patient is different, the electro-hydraulic push rod 10 can be started so that the output end of the electro-hydraulic push rod 10 pushes the base 1 to move, thereby adjusting the use height of the base 1, thereby improving applicability.

In Figures 1-4: elastic cushions 13 are provided on the base 1 and the support plate 2 to increase the comfort of the patient, and two strip blocks 14 are correspondingly provided on the base 1, and a U-shaped handle 15 is fixedly connected to the two strip blocks 14 for easy taking of the device, and an external fixing sleeve of the U-shaped handle 15 is provided with an anti-slip rubber sleeve 16 to prevent the user from slipping when holding the U-shaped handle 15.

In this embodiment, the electro-hydraulic push rod 10 is a well-known device for technical personnel in this field that is directly purchased on the market. It can be customized or selected according to actual needs. Here we only use it and do not make any structural and functional improvements to it. We will not go into details here. The electro-hydraulic push rod 10 is provided with a control switch that matches it. The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control. The technology is already very mature and can be implemented.

The implementation principle of a lower limb stretching exerciser in the embodiment of the present application is as follows: first, with the cooperation of the electro-hydraulic push rod 10 and the support seat 11, the base 1 is stably placed in the use position. At the same time, the electro-hydraulic push rod 10 can be started, and the use height of the base 1 can be adjusted accordingly under the action of the electro-hydraulic push rod 10. After the base 1 is stably placed in the use position, when performing lower limb rehabilitation training for patients with lower limb injuries, first let the patient sit on the base 1, and the patient's back can lean on the support plate 2. Then, through the cooperation of the mounting frame 8 and the positioning rod 9, the legs are fixed and limited on the connecting plate 4. The patient's legs gradually exert force to drive the connecting plate 4, which is rotatably connected to the base 1 through the connecting rod 5, to rotate. Through the cooperation of the connecting buckle 6 and the composite spring 7, the connecting plate 4 has a certain resistance when rotating, which can play a role in exercising the patient's lower limb strength, and at the same time, it can also perform appropriate and simple traction on the patient's legs.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
