[0002] In order to adapt to the patient's postoperative needs, hospital beds are usually equipped with functions such as position adjustment, installation protection, and hygiene management to facilitate medical staff or accompanying personnel to carry out daily care work for patients.

[0003] For some patients, such as orthopedic patients or stroke patients, who need hand rehabilitation training after surgery, there are usually two traditional methods: one is to transfer the patient to a special rehabilitation training device via a cart. This method involves the movement and transportation of the patient. Medical staff need to carefully move the patient onto the cart, then push it to the designated rehabilitation training area, and then transfer the patient from the cart to the rehabilitation training device; the other method is to push the rehabilitation equipment and temporarily place it at the bedside for the patient to use. This requires carrying larger rehabilitation equipment and ensuring that the equipment is placed firmly at the bedside, which is also more troublesome to operate.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-8 This application is described in further detail.

[0042] Example 1

[0043] The present application embodiment discloses a modular electric hospital bed with rehabilitation effect. Figure 1 The electric bed includes a bed frame 1 and guardrails arranged on both sides of the bed frame 1. The bed frame 1 supports the entire bed, and the guardrails provide left and right side protection for the patient to prevent the patient from accidentally rolling off the bed, thereby ensuring the patient's safety.

[0044] Furthermore, the guardrail includes a guardrail body 2 and an armrest 3. The armrest 3 is detachably mounted on the side of the guardrail body 2 near the bedside. The armrest 3 has a handhold 31 for the patient to grasp. When the armrest 3 is secured to the side of the guardrail body 2 near the bedside, the patient can grasp the armrest 3 to provide support, facilitating the patient's ability to stand up or adjust their posture. A mounting seat 4 is slidably mounted on the side of the guardrail body 2 facing the inside of the bed. The armrest 3 is detachably secured to the mounting seat 4, allowing the armrest 3 to be removably secured to the mounting seat 4 after being removed from the guardrail body 2. A sliding groove 21 is defined on the inner sidewall of the guardrail body 2 for the mounting seat 4 to slide. A drive mechanism 5 is provided within the guardrail body 2 to drive the mounting seat 4 to slide back and forth along the sliding groove 21. This design allows the armrest 3 to be mounted on the side of the guardrail body 2 facing the bedside and to move with the mounting seat 4, thereby assisting patients with limited upper limb mobility in passive rehabilitation training. As the armrest 3 moves, the patient's hand can follow its trajectory, thereby moderately exercising the hand joints and muscles. In addition, for patients with insufficient grip strength, the armrest 3 can be used with straps or gloves to ensure that the hand is firmly fixed on the armrest 3 to prevent accidental slipping during training.

[0045] Reference Figure 1 and Figure 2 In the embodiment of the present application, the lower end of the guardrail body 2 can be detachably fixed to the bed frame 1 by means of bolts or the like. Optionally, the lower end of the guardrail body 2 can be fixedly connected to a plurality of connecting seats 25, and the side wall of the bed frame 1 is also welded and fixed with a connecting plate 11 along its own length direction. The connecting plate 11 is provided with a plurality of groups of threaded holes at intervals along its own length direction, and each connecting seat 25 can be provided with four openings in a circumferential direction, so that by providing bolts passing through the openings and being threadedly connected to the threaded holes, the connecting seat 25 can be detachably fixed to the connecting plate 11, that is, the guardrail body 2 can be detachably fixed to the bed frame 1; at the same time, by providing a plurality of groups of threaded holes, the position of the guardrail body 2 can also be moved along the length direction of the bed frame 1, so that the position of the armrest seat 3 can be adjusted according to the arm length of different patients, thereby improving the adaptability of the patient's use.

[0046] Reference Figure 2 and Figure 3In the embodiment of the present application, the motion slide groove 21 includes a first section groove 211, a second section groove 212 and a third section groove 213 which are connected to each other in sequence. The first section groove 211 extends in the horizontal direction, the second section groove 212 extends in the vertical direction, and the lower end of the second section groove 212 is connected to the end of the first section groove 211 away from the head of the bed, the upper end of the third section groove 213 is connected to the upper end of the second section groove 212, and the lower end of the third section groove 213 is connected to the end of the first section groove 211 close to the head of the bed. The third section groove 213 can be set as an oblique groove or an arc-shaped groove; the first section groove 211, the second section groove 212 and the third section groove 213 are all connected by an arc-shaped groove, and the cross-section of the mounting seat 4 can be circular, so as to facilitate the movement of the mounting seat 4 along the motion slide groove 21.

[0047] This design allows for more diverse motion paths for the mounting base 4, allowing patients to undergo rehabilitation training in various directions. For example, when the mounting base 4 slides horizontally back and forth within the first slot 211, the patient's arm straightens and bends as the armrest 3 reciprocates, exercising the elbow joint. When the mounting base 4 slides up and down within the second slot 212, the patient's arm straightens and rises and falls with the armrest 3, exercising the shoulder joint. When the mounting base 4 repeatedly moves within the third slot 213, both the elbow and shoulder joints can be exercised simultaneously.

[0048] Reference Figure 3 and Figure 4 The drive device 5 includes a sprocket 51, a chain 52, a drive shaft 53, and a power source 54. A drive chute 22 is provided within the guardrail body 2 for the circumferential sliding of the chain 52, extending in the same direction as the motion chute 21. The sprocket 51 is rotatably disposed within the guardrail body 2 and meshes with the chain 52. The power source 54 is used to drive the sprocket 51 in rotation. The drive shaft 53 is connected between the mounting base 4 and the chain 52. The rotation of the chain 52 drives the drive shaft 53 to move, thereby enabling the mounting base 4 to slide along the motion chute 21. Specifically, the sprocket 51 has evenly distributed teeth on its surface, which mate with the links of the chain 52 to ensure stable and accurate transmission. The sprocket 51 can be made of alloy steel, which has high hardness, good wear resistance, and can withstand large torques without damage. The chain 52 is a conventional transmission chain 52, with each link tightly connected and flexible to accommodate motion conversion in different directions. The power source 54 can be a motor, whose output shaft is coaxially connected to the sprocket 51. Optionally, a reduction device can be configured to cooperate with the motor to accurately control the movement speed of the mounting base 4; in order to facilitate the control of the movement of the armrest base 3, a sensing device can also be used to accurately control the movement position of the mounting base 4.

[0049] In an optional embodiment, three sprockets 51 are preferably provided, respectively disposed at the arc-shaped junctions of the first groove 211, the second groove 212, and the third groove 213, and each sprocket 51 is aligned with a link of the chain 52. This arrangement enables the chain 52 to rotate smoothly at each turning point, ensuring efficient operation of the drive device 5. Three power sources 54 can be provided, or one can be provided, and is used to control any of the sprockets 51.

[0050] In other embodiments, the driving device 5 can also adopt a combination of gears and racks. For example, a rack is arranged in a circumferential direction inside the guardrail body 2 corresponding to the trajectory of the moving slide 21, and then the gear is driven to rotate by the power source 54, so that the gear can slide along the extension direction of the rack when meshing with the rack. The mounting seat 4 is connected to the gear shaft, and the mounting seat 4 can be driven to move by the movement of the gear.

[0051] Reference Figure 3 and Figure 4 To ensure the stability of the movement of the mounting base 4, a circumferential limit groove 41 is provided on the side wall of the mounting base 4. The guardrail body 2 is provided with circumferential positioning strips 23 on the side walls of the motion groove 21. When the mounting base 4 slides along the motion groove 21, the positioning strips engage within the limit groove 41, preventing the mounting base 4 from deviating from its motion trajectory. The limit groove 41 is an annular groove, and the positioning strip is a raised strip. The two cooperate like a track and a slider. The positioning strip can be made of an alloy material with high strength and can maintain its shape for a long time.

[0052] Reference Figure 3 and Figure 5 In the embodiment of the present application, two connecting posts 32 are fixed vertically at intervals on the side wall of the armrest base 3 facing the guardrail body 2. The guardrail body 2 is provided with a first connecting groove 24 on the side facing the bed head for the connecting posts 32 to be inserted into, and a first fixing member 6 is provided to fix the connecting posts 32 in the first connecting groove 24. The first fixing member 6 can be a combination of a bolt and a nut. By providing through holes in the side walls of the guardrail body 2 and the connecting posts 32, after the connecting posts 32 are inserted into the first connecting groove 24, the bolts are sequentially passed through the guardrail body 2 and the connecting posts 32, and tightened with the nuts to achieve fixation. In other embodiments, a slider can also be used for fixation.

[0053] Reference Figure 6 and Figure 7The mounting base 4 is provided with a rotating ring 42 on one side thereof which is rotatable toward the inner side of the bed. The rotating ring 42 is provided with a second connecting groove 43 for the connecting column 32 to be inserted therein, and a second fixing member 7 is provided for fixing the connecting column 32 in the second connecting groove 43. Specifically, the second fixing member 7 includes a fixed arc rod 71, a first spring 72 and a control handle 73. An arc groove for the fixed arc rod 71 to slide is provided in the rotating ring 42, and one end of the arc groove is connected to the second connecting groove 43. The first spring 72 is arranged in the arc groove and is located at the end of the fixed arc rod 71 away from the second connecting groove 43. An arc-shaped connecting hole is provided on the connecting column 32, and a landing groove is provided on the side of the second connecting groove 43 away from the arc groove. When the connecting column 32 is inserted into the second connecting groove 43, the fixed arc rod 71 can pass through the connecting hole and be inserted into the landing groove. At this time, the first spring 72 is in a compressed state, thereby fixing the connecting column 32 to the rotating ring 42; the control handle 73 is provided on the side wall of the fixed arc rod 71, and the rotating ring 42 extends from one end toward the inside of the bed, and the rotating ring 42 is provided with an arc-shaped clearance groove for the control handle 73 to slide. Two fixed arc rods 71 ​​are respectively provided on the rotating ring 42 corresponding to the two connecting columns 32. The two fixed arc rods 71 ​​are preferably provided on the same side, so that it is convenient to control the two control handles 73 at the same time with one hand to simultaneously control the two fixed arc rods 71. In the two sets of second fixing parts 7, two first springs 72 can be provided, or one first spring 72 can be shared.

[0054] During use, by pressing the control handle 73 to compress the first spring 72, the fixed arc rod 71 is withdrawn from the positioning groove and the connecting hole, thereby achieving the installation and separation of the armrest seat 3 and the rotating ring 42, which is convenient and quick to operate. The connecting column 32 is fixed to the rotating ring 42, and the armrest seat 3 is fixed to the mounting seat 4. At the same time, because the rotating ring 42 rotates within the mounting seat 4, when the mounting seat 4 moves with the driving device 5, especially when the mounting seat 4 moves between the first section groove 211, the second section groove 212, and the third section groove 213 to change the exercise mode, the armrest seat 3 can rotate with the direction perpendicular to the surface of the guardrail body 2 as the rotation center, so that the patient can always maintain a relatively comfortable grip when holding the mounting seat 4.

[0055] Reference Figure 6 and Figure 7In an optional embodiment, the mounting base 4 defines an annular groove 44 for circumferential rotation of the rotating ring 42. A plurality of first positioning grooves 45 are circumferentially defined on the bottom wall of the annular groove 44. The rotating ring 42 is provided with a first positioning hole 421. A removable positioning bolt 46 is provided on the mounting base 4. The positioning bolt 46 passes through the first positioning hole 421 and is threadedly engaged with the first positioning groove 45. In this manner, the positioning bolt 46 secures the rotating ring 42, restricting its rotation and thereby fixing the armrest 3 at a specific angle. When a patient exercises their elbow joint by sliding back and forth within a certain section of the motion chute 21, such as within the first section 211 alone, the armrest 3 is secured, restricting its rotational direction and improving exercise stability.

[0056] The implementation principle of the modular electric hospital bed with rehabilitation effect in the embodiment of the present application is as follows: in daily use, the armrest seat 3 is fixed to the side of the guardrail body 2 facing the bedside through the first fixing member 6, so that patients with physical disabilities can use the force to get up or adjust their posture; when the patient needs to perform passive exercise, the first fixing member 6 can be unlocked, the armrest seat 3 can be removed, and the armrest seat 3 can be fixed to the mounting seat 4 through the second fixing member 7, and then according to the exercise mode required by the patient, the mounting seat 4 is first moved to the first section groove 211, the second section groove 212 or the third section groove 213, and then the patient's hand is fixed to the armrest seat 3, and the power source 54 is started. The mounting seat 4 is controlled to move back and forth by the power source 54, so that the armrest seat 3 drives the hand to move, and rehabilitation exercise is performed on the corresponding part; after the exercise is completed, the armrest seat 3 is re-fixed to the side wall of the guardrail body 2.

[0057] Example 2

[0058] The difference between the embodiment of the present application and embodiment 1 is that a pull ring 33 is further provided on the armrest seat 3, and the patient can perform active exercise through the pull ring 33.

[0059] Reference Figure 1 and Figure 8 Specifically, in the embodiment of the present application, a pull ring 33, a stretching rope 34 and a winding piece 35 are further provided in the armrest seat 3, and a limit piece 8 for limiting the sliding of the mounting seat 4 is provided at the upper end of the second section groove 212 of the guardrail body 2. The pull ring 33 is detachably embedded in the armrest seat 3. Preferably, a groove for embedding the pull ring 33 is provided on the side wall of the armrest seat 3 facing away from the bed. The armrest seat 3 can be fixed in the groove by interference fit or by providing a positioning buckle.
