Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary equipment, and in particular to a displacement device. Background Technology
[0002] Hemiplegic patients often have weakness throughout their body. When they need to go to the toilet or transition from bed to wheelchair, they need to be moved by medical staff, which is extremely inconvenient. Existing technologies have documented the use of transfer devices for transition, such as the retractable sliding frame structure and medical bed for assisting in the transfer and turning of the patient from a lying position to a sitting position, which still relies entirely on medical staff to operate when the patient needs to be turned from a lying position to a sitting position. This still cannot solve the problem of the convenience of medical staff to move the patient. Utility Model Content
[0003] The purpose of this utility model is to provide a transfer device that solves the problem of how to reduce the operational difficulty for medical staff when paralyzed patients are transferred from lying down to sitting up in the prior art.
[0004] This utility model is implemented as follows: a transfer device for transferring patients on a hospital bed, including a base, a seat plate, and a connecting mechanism. One end of the seat plate is connected to the base through the connecting mechanism, and the other end is suspended. The seat plate includes a fixed seat and a movable seat. The movable seat is rotatably connected to the fixed seat. A driving mechanism is provided between the fixed seat and the movable seat. The driving mechanism is used to make the movable seat flush with the fixed seat or at an angle α.
[0005] Paralyzed patients often lie flat on their hospital beds. When they need to use the toilet or be transferred, a transfer device is required to move them between the bed and their destination / wheelchair. However, because hemiplegic patients cannot turn from lying down to sitting up on their own, medical staff are needed to assist them. This assistance process presents a certain level of difficulty for medical staff. To address this technical problem, this invention first uses a drive mechanism to adjust the movable seat and the fixed seat to be level, preventing secondary injury when the base plate is inserted under the patient. Since the base and the seat plate are connected at only one end, the other end can be inserted along the bed and under the patient, placing the patient's body on the seat plate. Then, the patient is rotated. Because the fixed seat and the movable seat are level during rotation, no injury is caused to the patient. Once the patient is in position, the drive mechanism is activated, and the movable seat rotates along the fixed seat, simultaneously moving the patient from lying down to sitting up. During this transition, the drive mechanism can automatically adjust, reducing the difficulty of operation for medical staff. Moreover, the movable seat and the fixed seat can be adjusted to be level, preventing secondary injury to the patient.
[0006] A further technical solution of this utility model is as follows: the fixed seat has a first embedding groove on its side, the movable seat has a second embedding groove on its side, and the driving mechanism includes a connecting rod, the two ends of which are rotatably connected to the first and second embedding grooves respectively. Therefore, during rotation, the connecting rod can drive the movable seat to rotate along the fixed seat, thereby enabling the patient to switch between lying and sitting positions. Simultaneously, due to the presence of the first and second embedding grooves, when adjusting the patient to a lying position or when the seat is inserted under the patient, the connecting rod can be retracted into the first and second embedding grooves, ensuring the flatness of the seat and preventing secondary injury to the patient.
[0007] A further technical solution of this utility model is: the driving mechanism further includes a linear motor, one end of which is rotatably connected to the first embedded groove and the other end is connected to the rotating part of the connecting rod. The linear motor is used to provide power for the rotation of the connecting rod, and during the rotation of the connecting rod, it drives the movable seat to rotate along the fixed seat, thereby realizing the angle adjustment between the two.
[0008] A further technical solution of this utility model is as follows: the connecting rod is provided with a receiving portion, and the connecting rod, the first embedding groove, and the second embedding groove form a parallelogram structure. The linear motor and the connecting rod can be housed in the first embedding groove and the second embedding groove. When the linear motor drives the connecting rod to rotate, the connecting rod can be housed between the first embedding groove and the second embedding groove, while the linear motor is housed between the first embedding groove and the receiving portion; the space is fully utilized, ensuring that the fixed seat and the movable seat are flush.
[0009] A further technical solution of this utility model is that the driving mechanism is located on both sides of the seat plate. This not only allows for stable adjustment of the angle between the fixed seat and the movable seat, but also functions as an armrest.
[0010] A further technical solution of this utility model is: the connecting mechanism is connected to one end of the fixed seat, and the movable seat is connected to the other end of the fixed seat. The movable seat needs to be placed on the bed, while the connecting mechanism is placed on the side of the bed; therefore, it is more reasonable for the movable seat and the connecting mechanism to be on opposite sides of the fixed seat.
[0011] A further technical solution of this utility model is that the α angle is an obtuse angle or a right angle, which conforms to the patient's body position when sitting or standing and the switching of positions.
[0012] A further technical solution of this utility model is: the connecting mechanism includes a drive motor for driving the seat plate to rise and fall, and auxiliary cylinders placed on both sides of the drive motor. Depending on the bed height, the height of the seat plate can be adjusted through the connecting mechanism to accommodate the seat plate against the bed, facilitating patient transfer; the combination of the drive motor and auxiliary cylinders reduces the load on the drive motor.
[0013] A further technical solution of this utility model is: a foot pedal is provided on the base, and the foot pedal and the connecting mechanism are located at the same end of the base. This facilitates patient fixation.
[0014] A further technical solution of this utility model is: the bottom of the base is equipped with rollers with brakes. It can be used as a wheelchair.
[0015] The beneficial effects of this utility model: When a paralyzed patient lies flat on a hospital bed, a transfer device is needed to move the patient between the bed and the destination / wheelchair when the patient needs to go to the toilet or be transferred. However, in this process, since the paralyzed patient cannot turn from lying down to sitting up on their own, medical staff are required to assist them. This assistance process is somewhat difficult for medical staff to operate. To address this technical problem, this utility model first adjusts the movable seat and the fixed seat to be level through a drive mechanism, so that the base plate is locked under the patient to avoid secondary injury. Since the base and the seat plate are only connected at one end, the other end can be locked under the patient along the hospital bed, so that the patient's body is on the seat plate. Then, the patient is rotated. When rotating the patient, since the fixed seat and the movable seat are level, it will not cause injury to the patient. After the patient is rotated into position, the drive mechanism is activated, and the movable seat rotates along the fixed seat, simultaneously moving the patient from lying down to sitting up. During this switching process, the drive mechanism can automatically adjust, reducing the operational difficulty for medical staff. Moreover, the movable seat and the fixed seat can be adjusted to be level, which will not cause secondary injury to the patient. Attached Figure Description

[0022] Example 1:
[0023] Figure 1-3 A transfer device for transferring a patient on a hospital bed is shown, comprising a base 1, a seat plate 2, and a connecting mechanism 3. One end of the seat plate 2 is connected to the base 1 via the connecting mechanism 3, and the other end is suspended. The seat plate 2 comprises a fixed seat 21 and a movable seat 22, the movable seat 22 being rotatably connected to the fixed seat 21. A driving mechanism 4 is provided between the fixed seat 21 and the movable seat 22, the driving mechanism 4 being used to make the movable seat 22 flush with or at an angle α to the fixed seat 21.
[0024] In this embodiment, the fixed seat 21 has a first embedding groove 23 on its side, and the movable seat 22 has a second embedding groove 24 on its side. The driving mechanism 4 includes a connecting rod 41, the two ends of which are rotatably connected to the first embedding groove 23 and the second embedding groove 24, respectively. Therefore, during rotation, the connecting rod can drive the movable seat to rotate along the fixed seat, thereby enabling the patient to switch between lying and sitting positions. Simultaneously, due to the presence of the first and second embedding grooves, when adjusting the patient to a lying position or when the seat is inserted under the patient, the connecting rod can be retracted into the first and second embedding grooves, ensuring the flatness of the seat and preventing secondary injury to the patient.
[0025] In this embodiment, the connecting rod includes a first rod body and a second rod body rotatably connected to the first rod body. The end of the first rod body is placed in a first embedding groove and rotatably connected to a fixed seat, and the end of the second rod body is placed in a second embedding groove and rotatably connected to a movable seat.
[0026] In this embodiment, both the first and second embedding slots are open-top structures.
[0027] In this embodiment, the drive mechanism 4 further includes a linear motor 42, one end of which is rotatably connected to the first embedded groove 23 and the other end is connected to the rotation point of the connecting rod 41. The linear motor provides power for the rotation of the connecting rod, which drives the movable seat to rotate along the fixed seat during the rotation of the connecting rod, thereby realizing the angle adjustment between the two.
[0028] In this embodiment, the connecting rod 41 is provided with a receiving portion. The connecting rod 41, the first embedding groove 23, and the second embedding groove 24 form a parallelogram structure. The linear motor 42 and the connecting rod 41 can be housed within the first embedding groove 23 and the second embedding groove 24. When the linear motor drives the connecting rod to rotate, the connecting rod can be housed between the first embedding groove and the second embedding groove, while the linear motor is housed between the first embedding groove and the receiving portion. The space is fully utilized, ensuring that the fixed seat and the movable seat are flush.
[0029] In this embodiment, the drive mechanism 4 is located on both sides of the seat plate 2. It can not only stably adjust the angle between the fixed seat and the movable seat, but also serve as a handrail.
[0030] In this embodiment, the connecting mechanism 3 is connected to one end of the fixed seat 21, and the movable seat 22 is connected to the other end of the fixed seat 21. The movable seat needs to be placed on the bed, while the connecting mechanism is placed on the side of the bed. Therefore, it is more reasonable for the movable seat and the connecting mechanism to be on opposite sides of the fixed seat.
[0031] In this embodiment, the movable seat rotates upwards along the rotation direction of the fixed seat, and the connecting mechanism is located below the fixed seat.
[0032] In this embodiment, the movable seat is provided with a handle.
[0033] In this embodiment, the α angle is an obtuse angle or a right angle, which corresponds to the patient's body position when sitting and the switching between positions.
[0034] In this embodiment, the connecting mechanism 3 includes a drive motor 31 for driving the seat plate 2 to rise and fall, and auxiliary cylinders 32 placed on both sides of the drive motor 31. Depending on the bed height, the height of the seat plate can be adjusted through the connecting mechanism to accommodate the seat plate against the bed, facilitating patient transfer; the combination of the drive motor and auxiliary cylinders reduces the load on the drive motor.
[0035] In this embodiment, the drive motor drives the threaded rod to move along the threaded sleeve through a gear set, thereby realizing the lifting and lowering of the seat plate.
[0036] In this embodiment, a foot pedal 5 is provided on the base 1, and the foot pedal 5 and the connecting mechanism 3 are located at the same end of the base 1. This facilitates patient fixation.
[0037] In this embodiment, the foot pedal is tilted for the convenience of the patient.
[0038] In this embodiment, the base 1 is equipped with braked casters 6 at its bottom, allowing it to be used as a wheelchair.
[0039] In this embodiment, the fixing base includes a square steel bar and a fixing base body. The square steel bar is connected to the connecting mechanism, and the fixing base body is fixed to the top of the square steel bar by a reinforcing member. The fixing base has higher stability.
[0040] The working principle of this invention: When a paralyzed patient lies flat on a hospital bed, a transfer device is needed to move the patient between the bed and the destination / wheelchair when the patient needs to use the toilet or be transferred. However, since the paralyzed patient cannot turn from lying down to sitting up on their own, medical staff are required to assist them. This assistance process is somewhat difficult for medical staff. To address this technical problem, this invention first uses a drive mechanism to adjust the movable seat and the fixed seat to be level, so that the base plate can be inserted under the patient without causing secondary injury. Since the base and the seat plate are only connected at one end, the other end can be inserted under the patient along the bed, so that the patient's body is on the seat plate. Then, the patient is rotated. During the rotation, since the fixed seat and the movable seat are level, no injury will be caused to the patient. After the patient is rotated into position, the drive mechanism is activated, and the movable seat rotates along the fixed seat, simultaneously moving the patient from lying down to sitting up. During this switching process, the drive mechanism can automatically adjust, reducing the difficulty of operation for medical staff. Moreover, the movable seat and the fixed seat can be adjusted to be level, which will not cause secondary injury to the patient.
