[0002] Examination beds are dedicated beds in medical institutions used for patient diagnosis and treatment. They are typically equipped with mattresses and pillows to enhance patient comfort. Paper sheets are often laid on top of the mattress, and these sheets are changed after each patient to ensure cleanliness and reduce the risk of cross-infection. Furthermore, using disposable paper sheets avoids the bacterial growth problems that can occur with traditional cloth sheets during washing and reuse, thus more effectively protecting patient health and safety. Currently, paper sheets on examination beds are often manually changed by medical staff, increasing their workload. Furthermore, unsterilized paper sheets may pose a risk of cross-infection. Timely disposal of used paper sheets is also necessary to prevent environmental and human contamination. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a treatment bed with an automatic paper sheet replacement function. This function can automatically replace the paper sheet laid on the treatment bed, reducing the workload of medical staff. Furthermore, the paper sheet can be disinfected promptly during the rolling process, thus avoiding pollution and harm to the environment and human body.

[0004] In view of this, the present invention provides a medical bed with an automatic paper sheet replacement function, including a bed frame and a mattress set on top of the bed frame, and an automatic paper sheet unwinding device set on both sides of the bed frame along the length of the bed frame. The automatic paper sheet unwinding device includes an unwinding section set on either the head or foot of the bed, and a corresponding winding section set on the other side. A clean sheet is laid on the surface of the mattress from the unwinding section and connected to the winding section on the other side. The winding section can wind up the used sheet. The winding roller in the winding section is used to wind up the used sheet. The winding roller is set in a disinfection chamber, and a disinfection unit is set in the disinfection chamber.

[0005] In this technical solution, the bed sheet is connected to the unwinding section and the rewinding section, which enables automatic bed sheet replacement. At the same time, the rewinding roller of the rewinding section is set in the disinfection chamber, which can disinfect and rewind the used bed sheet. This device avoids manual bed sheet replacement and laying, reduces the burden on medical staff, and can promptly disinfect the used bed sheet, avoiding pollution and harm to the environment and human body.

[0006] In the above technical solution, the unwinding section further includes first fixed plates disposed on both sides of the end of the bed body, an unwinding roller rotatably disposed between the first fixed plates, the unwinding roller being used to cover a clean bed sheet, and a guide roller rotatably disposed between the two first fixed plates on the upper side of the unwinding roller.

[0007] In the above technical solution, the take-up section further includes a take-up roller rotatably disposed on the side of the bed away from the unwinding section. The take-up roller is connected to a drive section, which can drive the take-up roller to rotate. The take-up roller is rotatably disposed in the disinfection chamber of the disinfection compartment. The disinfection compartment includes a shell with an opening at one end. The shell is fixedly disposed on a second fixed plate on the side away from the opening. The second fixed plate is fixedly connected to the bed. A closing plate for closing the disinfection compartment to form the disinfection chamber is hinged to the opening side of the bed. A third fixed plate is provided at one end of the bed at the unwinding section. A locking component for locking the closing plate is provided on the third fixed plate. A paper inlet communicating with the internal disinfection chamber is provided on the side wall of the disinfection compartment.

[0008] In this technical solution, the drive unit is a common setup of a motor, pulley, and transmission belt, which can drive the winding roller to rotate and wind up the bed sheet. Therefore, it will not be described in detail. The locking component can be any locking structure in the prior art, as long as it can achieve a closable connection between the closing plate and the disinfection chamber.

[0009] In the above technical solution, the disinfection unit is a set of ultraviolet lamps installed in the disinfection chamber, which can irradiate and sterilize the sheets that enter the disinfection chamber from the paper inlet.

[0010] In this technical solution, at least one ultraviolet lamp group is set, depending on the material of the paper sheet. Different paper sheet materials may have different transmittance of ultraviolet light. When setting a single ultraviolet lamp group, it is necessary to confirm that the selected paper sheet material can be effectively penetrated by ultraviolet light. When setting two ultraviolet lamp groups, they are set on both sides of the sheet. After the sheet enters the disinfection chamber and is disinfected by the ultraviolet lamp group, it is rolled up on the take-up roller.

[0011] In the above technical solution, the ultraviolet lamp assembly further includes an ultraviolet lamp body that extends along the length of the disinfection chamber. A fixed sliding plate is provided on the back of the ultraviolet lamp body. The fixed sliding plate is slidably disposed in a sliding groove opened on the mounting block. The mounting block is fixedly disposed on the inner wall of the disinfection chamber.

[0012] In the above technical solution, further, the bottom of the bed is connected to a base via a support plate. The base includes a bracket, the ends of which are connected to casters. A mesh plate is provided in the middle of the bracket, and the mesh plate and the bracket form an upward-opening placement area.

[0013] In this technical solution, the casters facilitate the movement of the treatment bed, while the mesh panel and support form a placement area that can be used to place clean paper sheets or other medical supplies.

[0014] Furthermore, the above technical solution also includes an anti-deviation component, which is located on one side of the winding section and can adjust the position of the bed sheet during winding.

[0015] In the above technical solution, the anti-deviation component further includes an anti-deviation roller, which is adjustablely disposed between the third fixed plate and the second fixed plate. Photoelectric sensors are disposed at both ends between the anti-deviation roller and the bed, and the photoelectric sensors are disposed on the connecting plate. The connecting plate and the end of the bed are fixedly connected. A pushing unit is disposed on the third fixed plate, which can push the anti-deviation roller on the same side to move and adjust.

[0016] In this technical solution, the pushing unit can be a cylinder, a hydraulic rod, or an electric telescopic rod. If either of the photoelectric sensors at both ends is not blocked by the upper paper sheet, a shift occurs, and the pushing unit pushes the anti-deviation roller to move until both photoelectric sensors at both ends are blocked by the top paper sheet. The pushing unit, photoelectric sensors, and PLC control unit are electrically connected. The PLC control unit in this patent adopts existing technology, and its specific implementation, function, and performance are all based on existing mature technology. Therefore, it will not be discussed in detail in the patent text.

[0017] In the above technical solution, a connecting ball is fixedly installed on one side of the anti-deviation roller. The connecting ball is rotatably installed in the rotating groove corresponding to the mounting base. The mounting base and the second fixed plate are fixedly connected.
