Description

Technical Field

[0001] This utility model relates to the technical field of medical assistive devices, specifically a bedside mobility aid for critically ill patients. Background Technology

[0002] Critically ill patients or those with limited mobility often face higher safety risks when moving around at the bedside. Due to their weakness, limited mobility, or limb dysfunction caused by illness, they are prone to falls and slips when attempting to get out of bed, stand, or walk, which can lead to secondary injuries such as fractures, abrasions, or even more serious complications. Furthermore, patients often require external assistive devices for support during bedside movements to improve safety and stability.

[0003] Early postoperative mobilization is an adjunctive treatment for critically ill patients who have not been transferred out of the intensive care unit but whose condition allows for bedside movement. By getting out of bed and moving around, patients can promote bowel movements, reduce abdominal distension, prevent intestinal adhesions, promote systemic blood circulation, promote wound healing, and prevent the formation of deep vein thrombosis in the lower extremities, thereby shortening the surgical recovery period. It truly transforms patients from passive to active movement, enhances their subjective awareness, boosts their confidence in overcoming the disease, and helps them better cooperate with treatment.

[0004] Currently, commonly used bedside assistive devices in hospitals include handrails for getting up, fixed guardrails, and simple walking aids. However, these devices generally suffer from problems such as limited functionality, poor adaptability, and inconvenient adjustment. For example, ordinary handrails are usually fixed structures and cannot be flexibly adjusted according to the patient's height, body type, or specific needs; simple walking aids are mostly stand-alone devices with low integration with the bed, requiring additional movement during use, increasing the operational burden on both patients and medical staff. Utility Model Content

[0005] To address the aforementioned problems, namely the issues raised in the background section, this utility model proposes a bedside mobility aid for critically ill patients. The bed includes a bed frame composed of a bed board, a mattress, and a pillow. Symmetrical trapezoidal grooves are provided on both sides of the bed board. One end of each pair of trapezoidal grooves connects to a corresponding threaded groove. The pair of threaded grooves connects to the bed board at the foot of the bed. A set of symmetrical threaded holes is provided on both sides of the bed board. The bedside mobility aid is installed on the trapezoidal grooves. The bedside mobility aid consists of a sliding plate, a trapezoidal sliding rod, an upper handle, and a side handle. The trapezoidal slide rod is fixedly connected to the lower part of one side of the skateboard. The trapezoidal slide rod is slidably placed in a trapezoidal groove. The upper handle is fixedly connected to the upper side of the skateboard. The side handle is installed on one side of the skateboard. The lower part of the skateboard is provided with symmetrical through holes. Each through hole matches the diameter of the corresponding threaded hole. The other side of the skateboard is equipped with a handrail adjustment structure. The handrail adjustment structure includes a lifting component and a fastening component.

[0006] A further feature of this invention is that the lifting assembly includes a lead screw, a turntable, a slider, a movable ring, a fixed ring, a spiral handle, and an arc-shaped buckle. One end of the other side of the slide plate has a straight groove, and the other end of the other side of the slide plate has an arc-shaped buckle. The two ends of the straight groove are respectively connected to one end of the lead screw. The upper end of the lead screw passes through the slide plate and is fixedly connected to the turntable. The slider is slidably placed in the straight groove. The lead screw is threadedly connected to the slider. The movable ring is fixedly connected to the outside of the slider. The fixed ring is fixedly connected to the outside of the slide plate and is located below the straight groove. The movable ring and the fixed ring both have circular through holes inside. The two sides of the movable ring and the fixed ring are both flat. The circular through holes of the movable ring and the fixed ring are concentric. The cross-section of the spiral handle is circular. One vertical rod of the spiral handle is connected to the movable ring by a bearing. One vertical rod of the spiral handle passes through the fixed ring. The other vertical rod of the spiral handle is snapped into the arc-shaped buckle. The fastening assembly is installed on the movable ring.

[0007] A further feature of this invention is that the fastening assembly includes a spring, a pull plate, and a locking rod; The vertical rod of the U-shaped handle is provided with a pair of slots, the included angle of the pair of slots is 90°, the pair of slots are located at the connection with the movable ring, one end of the locking rod passes through the outer plane of the movable ring, one end of the locking rod is engaged in one of the slots, the other end of the locking rod is fixedly connected to the pull plate, the spring ring is sleeved on the outside of the locking rod, and the two ends of the spring are respectively fixedly connected between the outer plane of the movable ring and the pull plate.

[0008] A further feature of this invention is that one end of a pair of bolts passes through the corresponding through holes and is threaded into the corresponding threaded holes.

[0009] A further feature of this invention is that the arc-shaped buckle is an elastic buckle.

[0010] A further feature of this invention is that a pair of limiting bolts are threaded into the corresponding threaded grooves to limit the sliding range of the slide plate and prevent the bedside mobility aid from accidentally detaching from the bed and causing a fall when the patient walks.

[0011] A further feature of this invention is that the upper handle, side handle, and the wristwatch layer are all covered with a soft rubber layer.

[0012] A further feature of this invention is that the spacing between a pair of through holes matches the spacing between a set of threaded holes (the spacing between a pair of through holes = the spacing between four threaded holes).

[0013] A further feature of this invention is that the upper horizontal bar of the spiral handle matches the upper horizontal bar of the upper handle, and the other vertical bar of the spiral handle does not exceed the outer edge of the skateboard.

[0014] A further feature of this invention is that a lower U-shaped bar can be provided on the underside of the skateboard, which can be used to hang objects when the bedside activity aid is used as a handrail, or for seriously ill patients, such as children, to hold onto the lower handle.

[0015] A further feature of this invention is that there is a certain distance between the upper handle and the spiral handle, making it easier for the patient to grip the upper handle.

[0016] The beneficial technical effects of this utility model are as follows: This utility model can adjust and fix the position of the bedside mobility aid by cooperating with the limiting bolt, through hole and threaded hole, which is convenient for patients of different heights. When the patient needs to move, the U-shaped handle is opened, and the U-shaped handle is perpendicular to the slide plate. With the cooperation of the lifting component and the fastening component, the lifting component can adjust the height of the U-shaped handle according to the patient's height. The fastening component can quickly lock the handrail after it is opened to ensure that there will be no accidental displacement during use. This allows the patient to stand and walk back and forth along the bedside while holding onto the U-shaped handle, which promotes intestinal peristalsis, reduces abdominal distension, prevents intestinal adhesions, and promotes blood circulation throughout the body. This device effectively solves the problem of the single function of existing bedside assistive devices. It can assist patients to get up and walk along the bedside. This device is very convenient to operate and use, and does not require frequent moving or adjustment of the equipment. Attached Figure Description

[0022] The following is a reference to the appendix. Figures 1-4 The preferred embodiments of this utility model are described below. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0023] This utility model proposes a bedside mobility aid for critically ill patients. Before use, the other vertical rod of the U-shaped handle 3 is locked in the arc-shaped buckle 5, and the slider 14 is located in the middle of the straight groove, which is the retracted state. When using this device, it is installed on the corresponding side according to the position of the bed (if the bed is not against the wall, it can be installed on the side that is convenient for the patient, or it can be installed on both sides as a guardrail). The trapezoidal slide rod 10 of the bedside mobility aid is slidably placed in a trapezoidal slide groove 1 (the side handle 6 faces the pillow). The corresponding limiting bolt 9 is screwed in to limit the bedside mobility aid in the trapezoidal slide groove 1. The bedside mobility aid is pushed to slide to the patient's forearm, making it easy for the patient to reach and grab the side handle 6 and the upper handle 2. After passing one end of a bolt 8 through the corresponding through hole and screwing it into the corresponding threaded hole 7, the other bolt 8 is tightened. Bolt 8 secures the bedside mobility aid to the patient's side, facilitating adjustments for patients of different heights. When getting up, the patient can grip the upper handle 2 (or side handle 6) to assist. When the patient needs to move, the medical staff pulls the pull plate 11 outward with one hand, causing the lever to disengage from the corresponding slot 13. At this time, the spring 12 is in a stretched state. The other hand pulls the vertical rod of the U-shaped handle 3, which is engaged in the arc-shaped buckle 5, rotating the vertical rod 90°. After the vertical rod of the U-shaped handle 3 rotates 90° along the movable ring 17 and the fixed ring 15, the pull plate 11 is released. The spring 12 causes the pull plate 11 and the lever to spring back, locking the lever in another slot 13 (if not fully aligned, the U-shaped handle 3 can be swung slightly left and right to lock the lever in the slot 13). At this time, the U-shaped handle 3 and the sliding plate 4 are perpendicular. Figure 3As shown, the patient gets up and helps themselves off the bed, holding onto the upper horizontal plate of the loop handle 3. After the patient stands still, the medical staff rotates the turntable, which drives the lead screw 16 to rotate. The lead screw 16 drives the slider 14 to slide upward along the straight groove (conversely, reversing the handle causes it to slide downward). The slider 14 drives the movable ring 17 to slide upward, which in turn drives the loop handle 3 to slide upward. One vertical rod of the loop handle 3 slides upward along the fixed ring 15. When the loop handle 3 slides to a suitable height for the patient to hold onto, the turntable is stopped. The height of the loop handle 3 can be adjusted according to the patient's height. After unscrewing a pair of bolts 8, the patient can slowly walk towards the foot of the bed while holding onto the loop handle 3. The loop handle 3 drives the trapezoidal slide of the sliding plate 4 through the movable ring 17 and the slider 14. The rod 10 slides along the trapezoidal groove 1. When the patient walks to one end of the bed, the patient is guided to turn 180° around the other vertical bar of the loop handle 3. The patient then walks towards the head of the bed while holding onto the loop handle 3. While walking, the patient can hold onto the horizontal or vertical bar of the upper handle 2, thus enabling the patient to stand and walk back and forth along the edge of the bed while holding onto the loop handle 3. This promotes intestinal peristalsis, reduces abdominal distension, prevents intestinal adhesions, and promotes blood circulation throughout the body. After the patient finishes walking, the device is returned to its initial state after the patient is helped to lie down on the bed. This device effectively solves the problem of the single function of existing bedside assistive devices. It can assist the patient to get up and walk along the bedside. The device is easy to operate and use, and does not require frequent moving or adjustment of the device.
