Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a transfer device for critically ill patients. Background Technology

[0002] Critically ill patients are those whose condition develops suddenly, is critical, and changes rapidly. The slightest carelessness can often lead to irreparable consequences. Therefore, doctors must be able to make correct judgments and determine treatment measures in a short period of time. In order to make correct judgments, many medical professionals have proposed practical and feasible methods based on their personal clinical experience and insights.

[0003] For example, Chinese Patent CN215535738U discloses a transfer device for critically ill patients, including a base and a lifting frame. A fixing block is fixedly connected to the upper surface of the base, and a groove is formed on the surface of the fixing block. An electric telescopic rod is rotatably connected to the inner wall of the groove. The telescopic end of the electric telescopic rod is rotatably connected to the surface of the lifting frame. A mounting plate is rotatably connected to the upper end of the lifting frame. A limiting groove and a through groove are formed on the upper surface of the mounting plate. A bed board is slidably connected to the inner wall of the limiting groove, and a roller is rotatably connected to the inner wall of the through groove. A rotating block is threadedly connected to the surface of the roller, and the surface of the rotating block is fixedly connected to the lower surface of the bed board. This transfer device for critically ill patients, by setting up a bed board, roller, rotating block, servo motor, and second baffle, activates the servo motor when the second baffle is moved, driving the roller to rotate and moving the bed board under the patient. Moving the second baffle again reverses the servo motor, moving the bed board back to its initial position.

[0004] The existing technology has the following problems:

[0005] Some existing transfer devices for critically ill patients on the market lack adjustable mechanisms at the bottom, leaving the wheels in a state of free rotation at all times. When transferring a critically ill patient to this transfer device, the moving device could potentially cause further harm, posing a safety risk. Furthermore, the height of the patient's bed differs from that of an operating table, making height adjustment mechanisms crucial. However, existing height adjustment mechanisms are complex in structure and operation. In the race against time for critically ill patients, time-consuming mechanisms are unacceptable. Utility Model Content

[0006] This invention provides a transfer device for critically ill patients to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A transfer device for critically ill patients includes a bed board. A first guardrail is fixedly connected to the top of the bed board. A first support rod is fixedly connected to the inner wall of the first guardrail. The bottom of the first support rod is fixedly connected to the top of the bed board. A second guardrail is fixedly connected to the top of the bed board. A second support rod is fixedly connected to the inner wall of the second guardrail. The bottom of the second support rod is fixedly connected to the top of the bed board. A connecting block is fixedly connected to the side of the bed board. A thin rod is fixedly connected to the bottom of the connecting block. A thick rod is slidably connected to the outer wall of the thin rod. A device base is fixedly connected to the bottom of the device base. A moving mechanism housing is fixedly connected to the bottom of the device base. A connecting plate is fixedly connected to the inner wall of the moving mechanism housing. A motor is fixedly connected to the top of the device base. A threaded rod is fixedly connected to the top of the motor.

[0009] A further improvement of this utility model is that: a rotating rod is rotatably connected to the front of the connecting plate, a roller is rotatably connected to the outer wall of the connecting plate, and a sliding rod is movably connected to the bottom of the rotating rod.

[0010] A further improvement of the present invention is that: a fixed frame is fixedly connected to the front of the connecting plate, the inner wall of the fixed frame is slidably connected to the outer wall of the sliding rod, and a sliding block is slidably connected to the inner wall of the fixed frame.

[0011] A further improvement of this utility model is that: a rocker arm is slidably connected to the inner wall of the sliding block, one end of the rocker arm is rotatably connected to the front of the fixed frame, and a spring is fixedly connected to the lower surface of the inner wall of the fixed frame, with the top of the spring fixedly connected to the bottom of the sliding block.

[0012] A further improvement of this utility model is that: the outer wall of the threaded rod is threadedly connected to a threaded collar, and the outer wall of the threaded collar is fixedly connected to an arc-shaped block.

[0013] A further improvement of this utility model is that the side of the arc-shaped block is fixedly connected to the side of the bed board.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a transfer device for critically ill patients, which uses the cooperation between a rotating rod and a sliding block. The state of the roller can be controlled by the contact and separation of the rotating rod with the roller. By adjusting the rotating rod, the roller can have two states: one where it cannot rotate and the other where it can rotate freely. This allows the device to switch freely according to the scenario, improving its adaptability. A rocker arm slides in the groove on the front of the sliding block. The groove on the top of the sliding block has a curved groove that can firmly hold the rocker arm in place, preventing the roller from easily switching between the two states. This avoids the situation where the roller easily changes state due to external forces without user operation, thus improving the stability of the device.

[0016] 2. This utility model provides a transfer device for critically ill patients, which uses the cooperation between a threaded rod and a thin rod. The rotation of the threaded rod causes the threaded sleeve to rise or fall, thereby driving the bed board to rise or fall, facilitating the transfer of critically ill patients to the bed board and saving time, increasing the rescue time for critically ill patients, and increasing the practicality of the device. The thin rod provides stable support for the rise or fall of the bed board, making the rise or fall of the bed board more stable, improving the safety and comfort of critically ill patients during the transfer process.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-6 As shown, this utility model provides a transfer device for critically ill patients, including a bed board 1. A first guardrail 11 is fixedly connected to the top of the bed board 1. A first support rod 12 is fixedly connected to the inner wall of the first guardrail 11. The bottom of the first support rod 12 is fixedly connected to the top of the bed board 1. A second guardrail 13 is fixedly connected to the top of the bed board 1. A second support rod 14 is fixedly connected to the inner wall of the second guardrail 13. The bottom of the second support rod 14 is fixedly connected to the top of the bed board 1. A connecting block 32 is fixedly connected to the side of the bed board 1. A thin rod 31 is fixedly connected to the bottom of the connecting block 32. A thick rod 3 is slidably connected to the outer wall of the thin rod 31. A device base 15 is fixedly connected to the bottom of the thick rod 3. A moving mechanism housing 2 is fixedly connected to the bottom of the device base 15. A connecting plate 23 is fixedly connected to the inner wall of the moving mechanism housing 2. A motor 33 is fixedly connected to the top of the device base 15. A threaded rod 34 is fixedly connected to the top of the motor 33.

[0027] In this embodiment, the critically ill patient is first transferred to the bed board 1. The rotating rod 21 is then stepped on, causing the end of the rotating rod 21 that was originally in contact with the roller 22 to separate from the roller 22. At this point, the roller 22 can rotate freely. The two connecting blocks 32 are pushed by hand to transfer the critically ill patient. The rotating rod 21 is then stepped on and released, causing the roller 22 to be unable to rotate. The motor 33 is then started, causing the bed board 1 to rise or fall. Once the bed board 1 is adjusted to a suitable height, the critically ill patient is transferred. The motor 33 is then started again to adjust the height of the bed board 1 to the next suitable height for transferring the critically ill patient. This completes the use of the critically ill patient transfer device. The rotating rod 21 can contact and separate from the roller 22 to control the state of the roller 22. By adjusting the rotating rod 21, the roller 22 can have two states: one where it cannot rotate and the other where it can rotate freely. This allows the device to switch freely according to the scenario, improving its adaptability.

[0028] Example 2

[0029] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a rotating rod 21 is rotatably connected to the front of the connecting plate 23, a roller 22 is rotatably connected to the outer wall of the connecting plate 23, a sliding rod 24 is movably connected to the bottom of the rotating rod 21, a fixed frame 25 is fixedly connected to the front of the connecting plate 23, the inner wall of the fixed frame 25 is slidably connected to the outer wall of the sliding rod 24, a sliding block 26 is slidably connected to the inner wall of the fixed frame 25, a rocker arm 27 is slidably connected to the inner wall of the sliding block 26, one end of the rocker arm 27 is rotatably connected to the front of the fixed frame 25, a spring 28 is fixedly connected to the lower surface of the inner wall of the fixed frame 25, and the top of the spring 28 is fixedly connected to the bottom of the sliding block 26.

[0030] In this embodiment, stepping on the rotating rod 21 causes the sliding rod 24 to descend, which in turn causes the sliding block 26 to descend, allowing the rocker arm 27 to slide on the inner wall of the sliding block 26. At this time, the spring 28 contracts. When the rocker arm 27 reaches the apex of the inner wall of the sliding block 26, the rotating rod 21 is released, and the spring 28 releases some of its elastic force, pushing the sliding block 26 up slightly. This causes the top of the rocker arm 27 to engage with the sliding block 26, disengaging the end of the rotating rod 21 that was originally in contact with the roller 22. The roller 22 can rotate freely. By pushing the two connecting blocks 32, critically ill patients can be transferred. Then, step on the rotating rod 21 and release it to make the roller 22 unable to rotate. The rocker arm 27 slides in the groove on the front of the sliding block 26. The groove on the top of the sliding block 26 has a curved groove that can hold the rocker arm 27 firmly, so that the roller 22 will not easily switch back and forth between the two states. This prevents the roller 22 from easily changing its state due to external force without the user's operation, thus improving the stability of the device.

[0031] Example 3

[0032] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the outer wall of the threaded rod 34 is threadedly connected to a threaded collar 35, and the outer wall of the threaded collar 35 is fixedly connected to an arc-shaped block 36, and the side of the arc-shaped block 36 is fixedly connected to the side of the bed board 1.

[0033] In this embodiment, by starting the motor 33, the threaded rod 34 is rotated, which in turn causes the threaded collar 35 to descend, which in turn causes the arc-shaped block 36 to descend, thereby raising or lowering the bed board 1. Once the bed board 1 is adjusted to a suitable height, the critically ill patient is transferred. Then, the motor 33 is started again to adjust the height of the bed board 1 to a suitable height for transferring the critically ill patient. This completes the use of the critically ill patient transfer device. The rotation of the threaded rod 34 causes the threaded collar 35 to rise or fall, which in turn causes the bed board 1 to rise or fall, facilitating the transfer of the critically ill patient to the bed board 1, saving time, increasing the rescue time for critically ill patients, and increasing the practicality of the device.

[0034] The working principle of the transfer device for this critically ill patient will be explained in detail below.

[0035] like Figure 1-6 As shown, first, the critically ill patient is transferred to bed board 1. The rotating rod 21 is stepped on, causing the sliding rod 24 to descend, which in turn causes the sliding block 26 to descend. This causes the rocker arm 27 to slide on the inner wall of the sliding block 26. At this time, the spring 28 contracts. When the rocker arm 27 slides to the apex of the inner wall of the sliding block 26, the rotating rod 21 is released, and the spring 28 releases some of its elastic force, pushing the sliding block 26 up slightly. This causes the top of the rocker arm 27 to lock onto the sliding block 26, disengaging the end of the rotating rod 21 that was originally in contact with the roller 22. At this point, the roller 22 can rotate freely. The two... Connect block 32 to transfer critically ill patients. Then step on rotating rod 21 and release it to prevent roller 22 from rotating. Start motor 33 to drive threaded rod 34 to rotate, which in turn drives threaded collar 35 to descend, which in turn drives arc block 36 to descend, which in turn raises or lowers bed board 1. When bed board 1 is adjusted to a suitable height, transfer critically ill patients. Then start motor 33 to adjust the height of bed board 1 to a suitable height for transferring critically ill patients. This completes the use of the critically ill patient transfer device.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
