Description

Technical Field

[0001] This utility model belongs to the field of transfer machine technology, and specifically relates to a flat-lying transfer machine. Background Technology

[0002] A patient transfer machine is a medical and nursing device used to transfer patients. However, the patient transfer machines currently on the market have many problems, such as: some transfer machines require the patient to have strong arms and legs and be able to sit upright on their own; some transfer machines require a 15cm gap between the bottom of the bed and the ground; some require the patient to be lifted up by the armpits when transferring the patient; and some lift the patient by pressing against the chest and abdomen.

[0003] In summary, existing transfer machines have various limitations and drawbacks in use, and paralyzed patients, with weak hands and feet and poor physical condition, are even less able to withstand the various ordeals during transfer. Utility Model Content

[0004] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a supine transfer machine that can transfer the patient from the bed to the transfer machine, thereby reducing the patient's suffering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A horizontally oriented patient transfer machine includes a base, a support seat, and a lifting mechanism. The support seat is mounted above the base via the lifting mechanism. A horizontal leg frame is hinged to the front end of the support seat, and a horizontal back frame is hinged to the rear end of the support seat. A telescopic cylinder is hinged to the bottom of the support seat. The bottom back of the back frame is hinged to the telescopic rod of the telescopic cylinder. The telescopic rod is also hinged to a connecting rod, which extends to the leg frame and is hinged thereto. The telescopic cylinder can drive the back frame to rotate upward around the rear end of the support seat, and at the same time drive the leg frame to rotate downward around the front end of the support seat via the connecting rod.

[0007] To better realize this utility model, the above structure is further optimized by including a leg and a connecting arm. The leg is horizontally hinged to the front end of the leg frame, and one end of the connecting arm is hinged to the bottom front end of the support base, and the other end is hinged to the bottom rear end of the leg frame. When the leg frame rotates downward around the front end of the support base, the connecting arm pushes the leg frame to rotate upward around the front end of the leg frame.

[0008] To better realize this utility model, the above structure is further optimized by including two pairs of support rods and upright arms horizontally arranged on the left and right sides of the support base. The bottom of the upright arm is hinged to the side of the support base, one end of the support rod is hinged to the side of the back frame, and the other end is hinged to the top of the upright arm. When the back frame rotates upward around the rear end of the support base, the back frame pushes the top of the upright arm to rotate upward through the support rod.

[0009] To better realize this utility model, the above structure is further optimized by hinged the top of the upright arm to the bottom of the support rod.

[0010] To better realize this utility model, the above structure is further optimized by providing four universal casters under the base.

[0011] To better realize this utility model, the above structure is further optimized. The lifting mechanism is a scissor-type lifting mechanism, and the lifting mechanism is driven by an electric telescopic cylinder.

[0012] To better realize this utility model, the above structure is further optimized. A cushion is provided above the support base, and a convenient opening is provided on the cushion. A detachable support pad is provided inside the convenient opening.

[0013] To better realize this utility model, the above structure is further optimized, and the telescopic cylinder is an electric telescopic cylinder or a hydraulic telescopic cylinder.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] The supine patient transfer machine provided by this utility model controls the height of the transfer machine through a lifting mechanism, making it easy to adapt to beds of different heights and allowing patients to be easily transferred onto the transfer machine, reducing the suffering of patients; at the same time, it uses a mechanical lever structure to raise the backrest and lower the leg support, transforming the transfer machine into a wheelchair mode, which facilitates daily care.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0028] Please refer to Figures 1-6This application provides a flat-lying transfer machine, including a base 1, a support 2, and a lifting mechanism 3. The support 2 is mounted above the base 1 via the lifting mechanism 3. A horizontal leg frame 4 is hinged to the front end of the support 2, and a horizontal back frame 5 is hinged to the rear end of the support 2. A telescopic cylinder 6 is hinged to the bottom of the support 2. The telescopic cylinder 6 can be an electric telescopic cylinder or a hydraulic telescopic cylinder. The hinged telescopic cylinder can swing to a certain extent during telescopic operation, avoiding the problem of jamming and locking of the mechanical lever structure during transmission, thereby improving the stability and smoothness of the device during deformation.

[0029] The bottom rear of the back frame 5 is hinged to the telescopic rod 601 of the telescopic cylinder 6, as shown below. Figure 6 As shown, in this embodiment, a connecting rod extending to the bottom is provided on the back of the back frame 5. The telescopic rod 601 is hinged to the connecting rod. By providing the connecting rod, the distance from this point to the hinge point at the rear end of the support seat 2 is increased, that is, the length of the lever arm is increased, so that the back frame 5 can obtain a larger torque when rotating upward, thereby improving the support performance of the back frame 5.

[0030] In order to achieve the linkage between the back frame 5 and the leg frame 4 during deformation, the telescopic rod 601 is also hinged with a linkage rod 7. The linkage rod 7 extends to the leg frame 4 and is hinged thereto. In order to avoid jamming during linkage, a certain tilt angle can be set at the part where the linkage rod 7 is connected to the leg frame 4.

[0031] The following action effect can be achieved through the linkage setting: when the telescopic cylinder 6 drives the back frame 5 to rotate upward around the rear end of the support base 2, it simultaneously drives the leg frame 4 to rotate downward around the front end of the support base 2 through the linkage rod 7. The upward rotation of the back frame 5 forms a backrest, and the downward rotation of the leg frame 4 forms leg support.

[0032] To enhance comfort, a footrest 8 and a connecting arm 9 are also included. The footrest 8 is horizontally hinged to the front end of the leg support 4. One end of the connecting arm 9 is hinged to the bottom front end of the support base 2, and the other end is hinged to the bottom rear end of the footrest 8. When the leg support 4 rotates downward around the front end of the support base 2, the connecting arm 9 pushes the footrest 8 to rotate upward around the front end of the leg support 4. After two opposing rotations (one up and one down), the leg support 4 tilts downward to provide leg support, while the footrest 8 remains horizontal, providing foot support.

[0033] This application transforms the patient transfer machine into a flat plate that can be laid flat by setting the back frame 5, support base 2, leg frame 4 and foot frame 8 on the same horizontal plane. When transferring patients, the bed and the flat plate are on the same plane, and the patient can be easily moved to the transfer machine by using the sliding pad under the patient.

[0034] To provide arm support, two pairs of support rods 10 and upright arms 11 are horizontally positioned on the left and right sides of the support base 2. The bottom of the upright arm 11 is hinged to the side of the support base 2, and one end of the support rod 10 is hinged to the side of the back frame 5, while the other end is hinged to the top of the upright arm 11. When the back frame 5 rotates upward around the rear end of the support base 2, the back frame 5 pushes the top of the upright arm 11 upward through the support rod 10, providing support for the support rod 10 through the back frame 5 and the upright arm 11. The arm can rest on the support rod 10, providing lateral support for the patient's body. Furthermore, the top of the upright arm 11 is hinged to the bottom of the support rod 10, making the upper surface of the support rod 10 a flat surface, thus improving comfort.

[0035] In addition, the following design features are included: four omnidirectional casters 101 are installed under the base 1 for pushing and moving the patient transfer machine. The lifting mechanism 3 is a scissor-type lifting mechanism, driven by an electric telescopic cylinder, which has a simple structure and good stability. A seat cushion 201 is installed above the support base 2, with a convenient opening. A removable support pad 202 is installed inside the convenient opening. After removing the support pad 202, the patient can urinate and defecate through the convenient opening. Furthermore, the rear end of the base 1 of this application does not have a supporting crossbar, but is designed as an open structure, allowing the patient transfer machine to be directly pushed above the commode for direct urination and defecation.

[0036] During transformation, the telescopic rod 601 of the telescopic cylinder 6 extends outward, pushing the back frame 5 to rotate upward around the rear end of the support seat 2, transforming the back frame 5 into the backrest of the wheelchair. The back frame 5, in turn, pushes the top of the upright arm 11 upward through the support rod 10, transforming the support rod 10 into the handle of the wheelchair. Simultaneously, the telescopic rod 601, through the connecting rod 7, drives the leg frame 4 to rotate downward around the front end of the support seat 2, transforming the leg frame 4 into the leg support of the wheelchair. As the leg frame 4 rotates downward around the front end of the support seat 2, the connecting arm 9 pushes the footrest 8 to rotate upward around the front end of the leg frame 4, transforming the footrest 8 into the foot pedal of the wheelchair. Finally, the transfer machine is transformed into a wheelchair, which is then moved out of the room by caregivers for treatment, sunbathing, etc.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
