Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a device for assisting stroke patients in getting out of bed. Background Art

[0002] Stroke is a very common cerebrovascular disease with an acute onset, rapid progression, and severe sequelae. It poses a serious threat to the patient's life, health, and quality of life, and even affects the entire family.

[0003] Stroke patients are often prone to unilateral limb numbness or weakness, facial numbness, crooked mouth corners, and staring in one direction. Symptoms include sudden limb weakness and collapse while walking, or falling to the ground when holding a cup unsteadily. Among them, difficulty getting up from bed is a problem faced by most stroke patients.

[0004] Existing bed-raising assistive devices are generally divided into two types: one is to support the patient's back and lift the patient through a flip-up support plate; the other is to use a power-assisting belt fixed at the end of the bed, and the patient pulls himself up through the power-assisting belt. The above existing bed-raising assistive devices have the following shortcomings:

[0005] 1. Most elderly stroke patients, when using power belts to help them get up, have to rely solely on the belts to pull themselves up due to their lack of strength. This not only makes it easy for them to be unable to pull themselves up during the getting up process or for the belts to slip out of their hands, but it can also cause strains in their upper limbs.

[0006] 2. Generally, for patients with mild symptoms, in order to avoid worsening of limb weakness, patients need to undergo appropriate rehabilitation exercises during the stable period of the disease. The patient is completely dependent on the flip board to lift the patient, and the patient lacks the opportunity to exercise during the process of getting up, which is poor in usability.

[0007] Therefore, how to design a device for assisting stroke patients in getting out of bed that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content

[0008] In order to solve the above problems, the purpose of the utility model is to provide a device for assisting stroke patients to get up, which solves the problem that the existing standing up assisting devices have single functions and patients lack the opportunity to safely perform standing up exercises.

[0009] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: comprising two groups of symmetrically arranged support assemblies, two groups of transmission devices symmetrically arranged and fixed at the bottom of the support assemblies, a flip plate arranged between the two groups of support assemblies, and a power-assisting belt arranged between the flip plate and the transmission assembly; the two groups of support assemblies each comprise a hand support plate and a fixed plate vertically fixed to the inner side of the hand support plate; the two groups of transmission devices each comprise a connecting plate, a servo motor, a transmission wheel 1, a transmission wheel 2, a transmission plate and a transmission belt; the connecting plate is fixedly arranged at the bottom of the hand support plate; the output end of the servo motor is connected to the transmission wheel 1 through a coupling, and the transmission wheel 1 is connected to the hand support plate through a coupling. The transmission wheel 1 is connected to the transmission wheel 2 through a transmission belt through a rotating shaft that is rotatable on the inner side of the connecting plate; a transmission rod is fixedly provided between the two transmission wheels 2; a square transmission block is fixedly provided at the center position of the outer side of the transmission wheel 2, and a buckle groove matching the transmission block is provided on the inner side of the transmission plate, and the square transmission block is embedded in the buckle groove; the outer side of the transmission plate is rotatable on the inner side of the connecting plate through a rotating shaft; a through groove is provided on the fixed plate, and the upper part of the transmission plate passes through the through groove and extends to the top of the fixed plate; one end of the power-assisting belt is fixedly provided on the outer peripheral wall of the transmission rod, and the other end is fixedly provided on the upper end surface of the flip plate.

[0010] Furthermore, a plurality of grip belts are provided on the power-assisting belt along the length direction of the power-assisting belt.

[0011] Furthermore, the two servo motors are both connected to an external power supply via a PLC controller.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model drives the transmission wheel and the transmission wheel 2 to rotate simultaneously through a servo motor, so that the flip plate flips upward and the power-assisting belt is wound and tightened. Compared with the ordinary pull-belt assistive device, the power-assisting belt is tightened to provide pulling force for the patient, and the flip plate provides support for the patient's back, so as to reduce the difficulty for the patient to stand up independently.

[0014] 2. According to the present invention, the patient can also choose to use the power belt to pull himself up under the support of the flip board as needed, so as to effectively exercise some muscles of the patient's upper body. If the patient's limbs are weak, the patient's upper body can be completely lifted by the flip board, thereby improving the flexibility of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0024] See also Figure 1-3 As shown, the invention comprises two groups of symmetrically arranged support components 1, two groups of transmission devices 2 fixedly arranged at the bottom of the support components 1 and symmetrically arranged, a flip plate 3 arranged between the two groups of support components 1, and a power-assisting belt 4 arranged between the flip plate 3 and the transmission components;

[0025] The two groups of support assemblies 1 each include a hand support plate 11 and a fixing plate 12 vertically fixed to the inner side of the hand support plate 11;

[0026] The two sets of transmission devices 2 each include a connecting plate 21, a servo motor 22, a transmission wheel 1 23, a transmission wheel 24, a transmission plate 25 and a transmission belt 26; the connecting plate 21 is fixedly arranged at the bottom of the hand support plate 11; the output end of the servo motor 22 is connected to the transmission wheel 1 23 through a coupling, the transmission wheel 1 23 is rotatably arranged on the inner side of the connecting plate 21 through a rotating shaft, and the transmission wheel 1 23 is connected to the transmission wheel 2 24 through a transmission belt 26; the two transmission wheels 2 4; a square transmission block 241 is fixedly provided at the center position of the outer side surface of the transmission wheel 24, a buckle groove 251 matching the transmission block 241 is provided on the inner side surface of the transmission plate 25, and the square transmission block 241 is embedded in the buckle groove 251; the outer side surface of the transmission plate 25 is rotatably arranged on the inner side surface of the connecting plate 21 through a rotating shaft; a through groove 121 is provided on the fixing plate 12, and the upper part of the transmission plate 25 passes through the through groove 121 and extends to the upper part of the fixing plate 12;

[0027] One end of the power-assisting belt 4 is fixed to the outer peripheral wall of the transmission rod 27, and the other end is fixed to the upper end surface of the flip plate 3.

[0028] The working principle is roughly as follows:

[0029] When in use, the fixing plate 12 is symmetrically placed between the mattress and the bed board to fix the use position of the fixing plate 12. The patient lies flat on the flip plate 3 and places both arms under the power-assisting belt 4. Figure 3 As shown, the resistance band is passed around the end of the bed, and the servo motor 22 is started at this time. The servo motor 22 drives the rotating wheel 1 to rotate, and the rotating wheel 1 drives the transmission wheel 24 to rotate through the transmission belt 26. When the two transmission wheels 24 rotate, on the one hand, they can drive the transmission rod 27 between the two transmission wheels 24 to rotate synchronously, and the power-assisting belt 4 is synchronously retracted during rotation. On the other hand, the outer side transmission block 241 drives the transmission plate 25 to rotate, and the transmission plate 25 can drive the flip plate 3 to flip upward with the transmission wheel 24 as the axis when rotating. The flip plate 3 supports the patient and assists the patient to stand up. At the same time, the patient holds the grip 41 of the power-assisting belt 4. Since the power-assisting belt 4 is retracted, the power-assisting belt 4 provides tension for the patient to stand up, which is convenient for the patient to stand up independently.
