Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a device that facilitates bed transfer. Background Technology

[0002] A bed-movement aid is a medical device or nursing assistive tool typically used to transfer patients from bed to other locations or to help patients change position in bed. It is commonly found in hospitals, nursing homes, or long-term care settings, especially for patients with limited mobility who are unable to move independently.

[0003] Existing bed transfer devices are mostly flat or consist of two foldable panels covered with a cloth cover. Since the process of transferring patients using bed transfer devices involves placing two beds side by side and then transferring the patient from one bed to the other by pushing them on the device, the large contact area between the flat device and the bed results in significant friction. Therefore, medical staff need to exert considerable effort to complete the entire transfer process. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a bed transfer device to solve the technical problem that the bed transfer device is in a flat state with a large contact surface with the hospital bed, which will generate greater friction and therefore require medical staff to exert a lot of effort to carry out the entire transfer process.

[0005] To achieve the above objectives, this utility model provides a bed-crossing device, which includes a first folding plate and a second folding plate, and the first folding plate and the second folding plate are hinged together.

[0006] Fabric covers are fitted onto the first and second folding plates;

[0007] Rolling elements are provided on the bottom outer surfaces of the first and second folding plates;

[0008] Pull rods are provided at the outer ends of the first and second folding plates.

[0009] Preferably, the rolling element is a ball wheel, and the ball wheels are distributed on both sides of the bottom surface of the outer end of the first folding plate and on both sides of the bottom surface of the outer end of the second folding plate.

[0010] Preferably, the tie rod includes a beam frame and sliding rods disposed at both ends of the beam frame;

[0011] The outer bottom surfaces of the first and second folding plates are symmetrically provided with rod sleeves.

[0012] The sliding rod is slidably connected to and through the sleeve. The body of the sliding rod is divided into a narrow rod with a small diameter and a thick rod with a large diameter. The outer end of the sleeve is provided with an annular end plate for limiting the thick rod.

[0013] Preferably, the beam frame and the sliding rod have hollow interiors and are interconnected.

[0014] The beam frame is equipped with a lever plate and locking rods at both ends of the lever plate, and the locking rods are located inside the sliding rod.

[0015] Preferably, the sliding rod has an opening, and an insert rod is slidably disposed inside the opening. The inner end of the insert rod forms a hemisphere, and the flat surface of the hemisphere is connected to the inner end of the insert rod. A second spring is sleeved on the insert rod, and the two ends of the second spring respectively abut against the inner wall of the sliding rod and the flat surface of the hemisphere.

[0016] The locking rod has a large-diameter extrusion section and a small-diameter retraction section, and the spherical surface of the hemisphere is in contact with the rod wall of the locking rod.

[0017] The beam frame is equipped with a first spring for pushing the lever. In its normal state, the spherical surface of the hemisphere is in contact with the pressing part of the locking rod.

[0018] Preferably, a fixed support is provided at the bottom of the inner end of the first folding plate, and a roller support is provided at the bottom of the inner end of the second folding plate. A hinge pin is fixedly provided on the roller support, and the hinge pin passes through the fixed support and is rotatably connected to it.

[0019] Preferably, the outer end of the first folding plate is provided with a pin, and the outer end of the second folding plate is provided with a buckle strap. When the first and second folding plates are in a folded state, the buckle strap can be engaged with the pin.

[0020] The beneficial effects of this utility model are:

[0021] This utility model allows medical staff to place the transfer bed on the target patient's bed. After the patient is transferred to the transfer bed, the transfer bed carrying the patient can be smoothly moved to another bed by pushing the first and second folding plates, in conjunction with the ball wheels at the bottom of the first and second folding plates. The entire transfer process reduces the friction between the first and second folding plates and the bed, thus reducing the force required to push the transfer bed. Attached Figure Description

[0035] A pull rod 5 is provided at the outer end of the first folding plate 1 and the second folding plate 2.

[0036] The rolling element is a ball wheel 3, and the ball wheels 3 are distributed on both sides of the bottom surface of the outer end of the first folding plate 1 and on both sides of the bottom surface of the outer end of the second folding plate 2.

[0037] The tie rod 5 includes a beam frame 51 and sliding rods 52 disposed at both ends of the beam frame 51;

[0038] Rod sleeves 6 are symmetrically provided on the bottom outer ends of the first folding plate 1 and the second folding plate 2;

[0039] The sliding rod 52 is slidably connected to the through rod sleeve 6. The rod body of the sliding rod 52 is divided into a narrow rod with a small diameter and a thick rod with a large diameter. The outer end of the rod sleeve 6 is provided with an annular end plate 61 for limiting the thick rod.

[0040] The beam frame 51 and the sliding rod 52 have hollow interiors and are connected to each other;

[0041] The beam frame 51 is equipped with a lever plate 53 and locking rods 54 located at both ends of the lever plate 53, and the locking rods 54 are located inside the sliding rod 52.

[0042] An opening is formed on the sliding rod 52, and an insert rod 55 is slidably disposed inside the opening. The inner end of the insert rod 55 forms a hemisphere, and the flat surface of the hemisphere is connected to the inner end of the insert rod 55. A second spring 551 is sleeved on the insert rod 55, and the two ends of the second spring 551 respectively abut against the inner wall of the sliding rod 52 and the flat surface of the hemisphere.

[0043] The locking rod 54 has a large-diameter extrusion part and a small-diameter retraction part, and the spherical surface of the hemisphere is in contact with the rod wall of the locking rod 54.

[0044] The beam frame 51 is equipped with a first spring 531 for pushing the lever. In its normal state, the spherical surface of the first spring 531 is in contact with the pressing part of the locking rod 54.

[0045] A fixed support 11 is provided at the bottom of the inner end of the first folding plate 1, and a roller support 21 is provided at the bottom of the inner end of the second folding plate 2. A hinge pin 22 is fixedly provided on the roller support 21, and the hinge pin 22 passes through the fixed support 11 and is rotatably connected to it.

[0046] The outer end of the first folding plate 1 is provided with a pin 12, and the outer end of the second folding plate 2 is provided with a buckle strap 23. When the first folding plate 1 and the second folding plate 2 are in a folded state, the buckle strap 23 can be engaged with the pin 12.

[0047] In this embodiment, the bed can be divided into three states according to its use: unfolded state, unfolded lever 5 extended state, and folded state. These three states will be described in detail below.

[0048] 1. In the unfolded state, medical staff can place this transfer device on the target patient's bed. After the patient is transferred to the transfer device, by pushing the first folding plate 1 and the second folding plate 2, and with the help of the ball wheels 3 at the bottom of the first folding plate 1 and the second folding plate 2, the transfer device carrying the patient can be smoothly moved to another bed. During the entire transfer process, the friction between the first folding plate 1 and the second folding plate 2 and the bed is reduced, and the force required to push the transfer device is reduced.

[0049] 2. With lever 5 extended: Since there may be a certain height difference between the two beds, or a certain distance between the two beds during the transfer of patients, lever 5 can be used to facilitate the lifting of the beds by medical staff.

[0050] Specifically, by holding the beam frame 51 and pressing the lever 53, the lever 53 moves the locking rod 54 under the action of overcoming the pre-tightening force of the first spring 531. At this time, the pressing part that contacts the spherical body of the insertion rod 55 changes to the retracting part. Since the diameter of the retracting part is smaller than that of the pressing part, the second spring 551 pushes the spherical body to make the insertion rod 55 retract into the sliding rod 52. At this time, the annular end of the outer end of the rod sleeve 6 can no longer restrict the sliding rod 52 through the insertion rod 55. The operator can then pull the beam frame 51 out from the bottom of the outer end of the first folding plate 1 and the second folding plate 2.

[0051] 3. Folded state: Since the rest of the structure is located at the bottom of the first folding plate 1 and the second folding plate 2, and the folding direction is also to fold to the bottom, after the folding is completed, it is in a folded state, and the buckle strap 23 on the outer end face of the second folding plate 2 can be fastened to the pin 12 on the outer end face of the first folding plate 1.
