Description

Technical Field

[0001] This invention relates to the field of transfer machine technology, and in particular to a swing arm type electric transfer device and method. Background Technology

[0002] People being cared for are prone to secondary injuries during manual transfer. Transfer machines are designed for patients or elderly people who are disabled, semi-disabled, or paralyzed and have difficulty moving. They can meet the differentiated needs of different occasions, families, and elderly people.

[0003] Currently, patient transfer machines are mainly divided into two types: seated transfer and suspended transfer. Seated transfer machines have limited functionality and can only meet the needs of short-distance transfers. However, daily activities such as getting up, bathing, using the toilet, and getting out of bed require a lot of intervention from caregivers, which places a heavy burden on them. The process of transferring patients to the transfer machine increases the risk of secondary injury to the patients.

[0004] While suspended motorized patient transfer machines offer strong functionality, they neglect the comfort needs of the patient. These machines place a cushion under the patient and lift it using a lifting mechanism, reducing the burden on caregivers. However, during lifting and transfer, the cushion tightly wraps around the body, restricting the patient's posture and increasing the risk of compression to the arms and sides, thus increasing the risk of secondary injury. For example, CN215821499U, a rehabilitation transfer machine, suffers from this problem because its sling is suspended by a frame. Both types of transfer machines fail to simultaneously meet the needs of functionality and patient comfort, posing a risk of secondary injury. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a swing-arm type electric transfer device and method. Through the setting of a lifting mechanism, a swing arm, and a fabric support, the person being cared for can be slowly lifted directly from the fabric support without the need for assistance from caregivers, thus reducing the burden on caregivers. The fabric support can fully support the body of the person being cared for and distribute their body pressure.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] A swing arm type electric displacement device includes a base and a fabric support. The top of the base has a vertical opening. A lifting mechanism is set at the opening of the base. It includes two parallel push rods and a drive mechanism. The tops of the two push rods are rotatably connected to one end of a fixed block, and the other end of the fixed block is fixedly connected to a swing arm. The swing arm has a swing angle mechanism at both ends. The swing angle mechanism is connected to a sleeve, and the support arm passes through the inside of the sleeve.

[0008] The fabric support is used to support the human body, and its two ends are connected and fixed to the support arm; the drive mechanism controls the movement of the two push rods, and drives the swing arm to swing through the fixed block to adjust the position of the fabric support; the swing angle mechanism is used to adjust the position of the support arm and the distance between the support arms.

[0009] As a further implementation, the fabric support includes two sleeves that fit and are fitted into the support arm, and the two sleeves are connected by fabric.

[0010] As a further implementation, a guide column is vertically arranged at the top opening of the base, and the lifting mechanism is arranged inside the guide column.

[0011] As a further implementation, a control console is fixed to the top of the guide column. The control console is equipped with control buttons for controlling the lifting mechanism and the swing mechanism. The swing mechanism includes a rotating block, which is connected to the rotating shafts at both ends of the swing arm and to the rotating mechanism inside the swing arm.

[0012] As a further implementation, a groove is provided at the bottom of the console near the swing arm, and an opening is provided at the top of the guide post near the swing arm. The groove is located at the top of the opening, and one end of the fixed block connecting push rod moves between the groove and the opening.

[0013] As a further implementation, a limiting baffle is provided at the bottom of the control console near the swing arm, the limiting baffle being used to limit the swing amplitude of the swing arm.

[0014] As a further implementation, a battery is installed on the side of the base to power the control console and the lifting mechanism. The control console is equipped with a power indicator panel.

[0015] As a further implementation, a caster wheel is provided on the bottom of the base away from the swing arm, and a straight wheel is provided on the other side. A pull rod is also provided on one side of the base. The pull rod is U-shaped and is rotatably connected to the base.

[0016] As a further implementation, end caps are provided at both ends of the support arm, and multiple through holes are provided along the length of the support arm. The end caps are fitted with sleeves to abut against both ends of the sleeve, and the through holes are used to fit pins to position the support arm.

[0017] A method for operating a swing-arm type electric transfer device, employing the swing-arm type electric transfer device as described above, includes the following steps:

[0018] Place the fabric support under the person being cared for;

[0019] The electric shifting device approaches the fabric support and adjusts the position of the support arm through the lifting mechanism. The sleeve and the sleeve of the fabric support cooperate, and the end cap and pin are installed for locking.

[0020] The lifting mechanism raises and adjusts the position of the swing arm, while the tilting mechanism adjusts the position of the support arm and the spacing between the support arms.

[0021] The electric displacement device moves to the designated position.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. This invention, through the design of a lifting mechanism, a swing arm, and a fabric support, allows for the slow and direct lifting of the person being cared for from the fabric support without the need for assistance from caregivers, reducing their burden. The fabric support provides full support for the person's body, distributing pressure accordingly. The lifting mechanism controls the swing arm to adjust the angle of the fabric support, ensuring the person moves in the most comfortable posture.

[0024] 2. This invention, through the setting of the swing angle mechanism, can further adjust the position and spacing of the support arms, making it suitable for medical personnel of different heights. It can also compensate for the problem of insufficient swing arm angle.

[0025] 3. The present invention uses through holes and end caps on the support arm, along with pins and sleeves, to lock the sleeve of the fabric support, preventing secondary injury to medical personnel during relocation.

[0026] 4. This invention enables the transfer of patients by lifting and lowering the lifting mechanism of the transfer device, reducing the burden on caregivers and overcoming the poor functionality of seated transfer machines. During the transfer process, the patient's body is distributed with force, and their posture can be adjusted at will. The robotic arm provides a "princess hug," overcoming the poor comfort of suspended electric transfer machines. Furthermore, the device is small in size, lightweight, and easy to operate, enabling easy and user-friendly short-distance transfer work. Attached Figure Description

[0033] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0034] As described in the background section, existing technologies such as seated transfer machines increase the burden on caregivers and pose secondary risks to patients, while suspended transfer machines are uncomfortable. In order to solve the above technical problems, this invention proposes a swing-arm type electric transfer device and method.

[0035] Example 1

[0036] In a typical embodiment of the present invention, reference is made to Figures 1-4 As shown, a swing arm type electric displacement device includes a base 10 and a fabric support. The top of the base 10 has a vertical opening. A lifting mechanism 5 is provided at the opening of the base 10. It includes two parallel push rods and a drive mechanism. The tops of the two push rods are rotatably connected to one end of a fixed block 31, and the other end of the fixed block 31 is fixedly connected to a swing arm 3. The swing arm 3 has a swing angle mechanism at both ends. The swing angle mechanism is connected to a sleeve 21, and the support arm 1 passes through the inside of the sleeve 21.

[0037] The fabric support frame in this embodiment is used to support the human body. Its two ends are connected and fixed to the support arm. The drive mechanism controls the two push rods to move in opposite directions. The fixed block 31 drives the swing arm 3 to swing to adjust the position of the fabric support frame. The swing angle mechanism is used to adjust the position of the support arm 1 and the spacing between the support arms 1.

[0038] Specifically, the fabric support includes two sleeves that fit and connect with the support arm 1. The two sleeves are connected by fabric. When medical personnel need to be moved, the fabric support is placed under them. The height of the swing arm 3 is adjusted by the lifting mechanism 5 so that the support arm 1 is aligned with the sleeves of the fabric support. After the sleeves are fitted with the support arm 1, the lifting mechanism 5 can slowly lift the medical personnel. Its principle is similar to a "princess carry." The fabric support supports the human body. Compared with a hanging bag, the fabric support can fully support the human body, distribute the body pressure, ensure that the human body can perform work in a comfortable posture, and improve the stability during the relocation process.

[0039] like Figure 1 and Figure 2 As shown, a guide post 51 is vertically fixed at the top opening of the base 10. The guide post 51 protrudes from the base 10 and is hollow. The lifting mechanism 5 is located inside the guide post 51.

[0040] The lifting mechanism 5 includes two push rods and a drive motor that controls the two push rods to complete the lifting movement. In this embodiment, the push rods can be lifting rods. The drive motor controls the lifting of the lifting rods. In short, any mechanism that can achieve the lifting of the push rods is acceptable.

[0041] The tops of the two push rods are rotatably connected to one end of the fixing block 31, and the other end of the fixing block 31 is fixedly connected to the swing arm 3, so that the swing arm 3 is positioned on one side of the guide post 51. The cross-section of the guide post 51 is oblong, and the two push rods are located inside the guide post 51 with a set distance. The two push rods move independently.

[0042] When both push rods rise simultaneously, the swing arm 3 can be raised via the fixed block 31; when lowered, the height of the swing arm 3 decreases accordingly. When the two push rods move in opposite directions, or when one push rod rises or falls while the other remains stationary, the fixed block 31 can rotate, thereby causing the swing arm 3 to rotate. This achieves the adjustment of the position of the support arm 1.

[0043] like Figure 1 As shown, a battery 6 is installed on one side of the base 10, which powers the drive motor. A control console 8 is fixed to the top of the guide column 51. The battery 6 powers the control console 8 and the lifting mechanism 5. The control console 8 contains a power indicator panel to display the battery level. The base 10 also has a charging port for charging the device.

[0044] The control console 8 is equipped with multiple control buttons, which are used to control the drive motor to achieve lifting and lowering movements. A groove is provided on the bottom of the control console 8 near the swing arm 3, and an opening is provided on the top of the guide post 51 near the swing arm 3. The groove is located at the top of the opening. One end of the fixed block 31 connected to the push rod moves between the groove and the opening, and the opening aligns with the groove. The space between the opening and the groove is greater than the movement space of the rotating block 31, so the rotation of the rotating block 31 is not affected.

[0045] A caster wheel 7 is installed on the bottom of the base 10, away from the swing arm 3, and a straight wheel is installed on the other side. A pull rod 9 is also installed on the side of the base 10 where the caster wheel 7 is installed. The pull rod 9 is U-shaped and is rotatably connected to the base 10. The device can be moved by the pull rod, caster wheel, and straight wheel.

[0046] In this embodiment, the swing angle mechanism is located at the end of the swing arm 3. It includes a rotating block, which is cylindrical. The rotating block is rotatably connected to the rotating shafts 22 at both ends of the swing arm 3. The rotating block is also connected to the rotating mechanism inside the swing arm 3.

[0047] like Figure 4 As shown in the principle diagram, the rotating mechanism preferably uses a rotating motor. The rotating motor and the rotating block are at a set distance. The rotating block is gear-shaped circumferentially, and the output end of the rotating motor is also a gear structure. It engages with the rotating block via a chain. The rotating motor is powered by a storage battery 6 and its operation is controlled by a control button. When the rotating motor rotates, it drives the rotating block to rotate via the chain.

[0048] The rotating block is connected to the sleeve 21 via a support rod of a set length. The rotation of the rotating block drives the sleeve 21 to rotate, thereby enabling the sleeve 21 to drive the support arm 1 to rotate.

[0049] In this embodiment, the swing angle of the swing arm 3 can be adjusted by setting the lifting mechanism 5. By setting the swing angle mechanism 2, the support arm can be further fine-tuned on the basis of adjusting the swing arm. At the same time, the distance between the first support arm 11 and the second support arm 12 can be changed, so that the device can adapt to medical personnel of different heights and also make up for the problem of insufficient swing arm angle.

[0050] In this embodiment, the change in the support arm spacing alters the distance between the two sleeves of the fabric support. When the fabric support supports a human body, the first support arm 11 supports the neck, and the second support arm 12 supports the popliteal fossa, similar to a "princess carry." This allows the human body to move in a more comfortable posture. The swing mechanism 2 ensures that the support arm 1 is higher than the swing arm 3, thereby preventing the fabric support from contacting the top of the swing arm.

[0051] A limit baffle is also provided at the bottom of the control console 8 near the swing arm 3. The limit baffle is used to limit the swing amplitude of the swing arm 3. This is to prevent the swing arm from losing control and causing secondary injury to the human body in the event of a sudden power failure.

[0052] like Figure 1 As shown, the support arm 1 is sleeved with the sleeve 21. The length of the support arm 1 is greater than the sleeve length of the fabric support. The end of the support arm 1 is provided with an internal thread for mating with the end cap 13. The end cap 13 is provided with an external thread on one side. The support arm 1 is in the shape of a round rod, and the other side of the end cap 13 is a circular baffle. The diameter of the baffle is greater than the diameter of the support arm 1 and the diameter of the sleeve.

[0053] The support arm 1 has multiple through holes along its length. The end cap 13 engages with the sleeve 21 at both ends of the sleeve. The through holes are used to engage pins to position the support arm 1. During relocation, the end cap 13 is removed, the support arm 1 is fitted onto the sleeve of the fabric support, and the end cap 13 is reinstalled to prevent the fabric support from slipping. The other end of the sleeve 21, away from the end cap 13, engages with the through holes via a pin, thus locking the sleeve 21 and end cap 13 onto the fabric support and ensuring stability during relocation.

[0054] In another example, the swing arm 3 is also equipped with an LED yellow light, which is powered by a battery and controlled by a control button on the console. The LED yellow light can prevent white light from hurting the eyes of the person being cared for, and also provide them with a warm and comfortable atmosphere, while facilitating nighttime relocation work.

[0055] This embodiment overcomes the problem of poor functionality of seated transfer machines by rotating the swing arm 3 and raising and lowering the lifting mechanism; and makes up for the shortcomings of hanging transfer machines in meeting the comfort requirements of the patients by using LED yellow light lighting and the combined application of support arm 1 and fabric bracket.

[0056] Example 2

[0057] A method for operating a swing-arm type electric displacement device includes the following steps:

[0058] Before the person being cared for needs to be moved, place the fabric support under the person being cared for;

[0059] The electric transfer device is placed near the fabric support, and the caregiver pushes the transfer device to the side of the bed where the person being cared for is located, extending the support part where the straight wheels are located under the bed and locking the casters.

[0060] Start the control button, and control the push rod to lift and lower according to the height of the bed through the drive motor in the lifting mechanism 5. Adjust the height of the support arm 1, and the sleeve of the fabric bracket cooperates with the sleeve 21. Install the end cover 13 and the pin to lock it.

[0061] The lifting mechanism 5 raises and adjusts the position of the swing arm 3, and the tilt mechanism 2 adjusts the position of the support arm 1 and the distance between the support arms to ensure the posture of the medical staff.

[0062] After the person being cared for is slowly raised to a suitable height, the caregiver opens the casters and slowly moves the device, using the lever to move the person to the desired location.

[0063] Twist the rotary button (left / right) on top of the control panel 8 to tilt and rotate the swing arm 3 to the appropriate angle (in conjunction with the button on the angle adjustment mechanism), and adjust the lifting mechanism to slowly place the person being cared for onto the prepared wheelchair or bed frame. This completes one transfer operation.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
