For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following is combined with Figure 1-5 The present application is further described in detail. An embodiment of the present application discloses a CT bed sheet changing device.

[0029] Reference Figure 1 and Figure 2 As shown, a CT bed sheet changing device includes a bed frame, a changing device and a control system.

[0030] The bed frame includes a bed base 100 and a bed body 110 mounted on the bed base 100, and the bed body 110 is used to support the patient to lie down. The bed base 100 can drive the bed body 110 to move in the vertical direction (height direction) and the horizontal direction (length direction), ensuring that the bed body 110 and the patient carried by it can smoothly enter the CT machine for examination. The bed frame corresponds to the scanning bed of the CT (computed tomography) machine in the prior art, and this application will not disclose it in detail.

[0031] The replacement device is installed on the side wall of the bed body 110, and its installation method can be adaptively adjusted according to needs and conditions. The replacement device includes a storage mechanism 200 and a storage mechanism 300 symmetrically fixedly installed on the two side walls of the bed body 110. They are used to store unused sheets and collect used sheets respectively. Efficient management of sheets and automated replacement process are ensured, which greatly simplifies the steps of sheet replacement, greatly improves work efficiency and reduces the workload of medical staff.

[0032] The disinfection mechanism 400 is installed in the storage mechanism 200 to disinfect the unused bed sheets that are replaced each time, thereby ensuring that each new bed sheet provided to the patient meets strict hygiene standards.

[0033] The control system is installed on the bed frame and is used to adjust and control the storage mechanism 200 and the storage mechanism 300. When the bed sheets need to be replaced, the control system adjusts the storage mechanism 300 and the storage mechanism 200 to roll up the used bed sheets and lay unused bed sheets to cover the surface of the bed body 110, thereby completing a continuous and seamless replacement operation. The entire replacement process is free from manual intervention, thereby significantly reducing the risk of cross infection.

[0034] Reference Figure 2 and Figure 3As shown, the storage mechanism 200 includes a receiving box 210 and a cover plate 220 .

[0035] The receiving box 210 is fixedly mounted on a side wall of the bed body 110 in the length direction, and its length direction is consistent with that of the bed body 110 to facilitate laying sheets of the same length.

[0036] The storage box 210 has a storage chamber 201 for storing rolled sheets. The storage chamber 201 has a feed port on one side wall of the storage box 210 in the width direction, which is convenient for users to put in or take out rolled sheets. The top surface of the storage box 210 has a discharge port 202 connected to the storage chamber 201. The length of the discharge port 202 matches the length of the bed body 110 to ensure the normal laying of the sheets. When the rolled sheets are placed in the storage chamber 201 through the feed port, the end of the sheets extends out of the discharge port 202 and bypasses the upper surface of the bed body 110 to be placed at the storage mechanism 300.

[0037] The cover plate 220 is detachably buckled at the feed port of the container box 210 and is made of easy-to-clean materials, which is convenient for daily maintenance and cleaning. The cover plate 220 not only prevents dust and other pollutants from entering the container chamber 201, but also protects the inner bed sheet from external pollution, ensuring that the bed sheet is clean and hygienic every time it is used.

[0038] The storage mechanism 200 also includes a fixed shaft 230 and a pressing assembly.

[0039] The fixed shaft 230 is used to carry and rotate the rolled sheets to ensure that unused sheets can be released smoothly. The fixed shaft 230 is installed inside the accommodating cavity 201 of the accommodating box 210, one end of which is connected to the side wall of the accommodating cavity 201 in the width direction, and the other end is connected to the cover plate 220, ensuring the stability of the fixed shaft 230.

[0040] The extrusion assembly consists of two groups, which are precisely installed on the side walls of the accommodating cavity 201 in the width direction and the cover plate 220 respectively.

[0041] Each set of the pressing assemblies includes a spring 250 and a slider 240 .

[0042] A slide groove 205 is provided on the inner wall of the accommodating box 210 in the width direction and the cover plate 220 . The slider 240 is slidably disposed in the slide groove 205 . The sliding direction thereof is horizontally slidably disposed along the width direction and the sliding direction thereof is perpendicular to the axial direction of the fixed shaft 230 .

[0043] The two ends of the fixed shaft 230 are respectively fixedly connected to the two sliders 240. The spring 250 is installed in the slide groove 205, one end of the spring 250 is fixedly connected to the side wall of the slide groove 205 away from the bed body 110, and the other end of the spring 250 abuts against the side of the slider 240 away from the bed body 110. In this way, the fixed shaft 230 and the slider 240 are pushed toward the bed by the spring 250, and the surface of the rolled bed sheet is pressed against the side wall of the length direction of the accommodating chamber 201. This prevents the bed sheet from being accidentally released in a tension-free state, and ensures that the bed sheet can be kept tight when in use.

[0044] When the rolled bed sheet is pulled for replacement, the storage mechanism 300 works to store the used part and release the new bed sheet. In this process, the preload force of the spring 250 needs to be overcome. When the replacement is completed, the rolled bed sheet will be tightly attached to the inner wall of the accommodating cavity 201 again under the action of the spring 250, and return to the initial tight state, ensuring that the bed sheet is always kept in the best use state.

[0045] A plurality of limit blocks 130 are also fixedly installed on the bed body 110. The limit blocks 130 are distributed in two groups and fixedly connected to the two ends of the head box and the foot of the bed. Each limit block 130 is provided with a limit groove 131 on the side facing the bed body 110. Both ends of the bed sheet on the bed body 110 are in the limit groove 131, so that the limit blocks 130 can make it fit tightly to the surface of the bed body 110, thereby ensuring that the bed sheet is laid flat.

[0046] Reference Figure 2 and Figure 3 As shown, the disinfection mechanism 400 includes an atomization plate 420 and an electric pump 430 .

[0047] A disinfection chamber 203 is provided at the corner of the top of the container box 210 away from the bed 110. The disinfection chamber 203 is not only used to store disinfectant, but also provides a stable installation platform for the atomization plate 420. A liquid inlet 204 and a sealing cover 410 are also provided at the top of the container box 210.

[0048] The atomizing plate 420 is fixedly mounted on the top of the accommodating chamber 201 and is arranged to fit closely with the disinfection chamber 203 to reduce the flow path of the disinfectant and ensure that the sprayed disinfectant can accurately cover the target area. The atomizing plate 420 is arranged at an angle, and a plurality of nozzles are fixedly mounted thereon, facing the side of the single vertical surface formed when the bed sheet extends from the discharge port 202. When the nozzle sprays the disinfectant, the disinfectant falls accurately on the top surface of the bed sheet after it is laid. The direction and position of the nozzle improve the coverage rate and disinfection efficiency of the disinfectant and reduce unnecessary waste.

[0049] The electric pump 430 is fixedly mounted on the outer wall of the container box 210 to pressurize the container box 210 so that the disinfectant is forced to be sprayed out through the nozzle. This ensures that the disinfectant can be evenly sprayed onto the bed sheet at an appropriate rate and pressure, thereby enhancing the disinfection effect. The stable pressure provided by the electric pump 430 helps to achieve uniform spraying of the disinfectant, further improving the disinfection quality.

[0050] The disinfection mechanism 400 also includes an ultraviolet lamp board 260, which is fixedly mounted on the inner wall of the accommodating cavity 201 near the bed body 110 and is symmetrically arranged with the atomizing plate 420. The ultraviolet lamp board 260 is arranged vertically so that the ultraviolet light emitted by it can directly and evenly cover the entire surface of the bed sheet. By vertically arranging the ultraviolet lamp board 260, all-round irradiation of the surface of the bed sheet is achieved, which greatly enhances the sterilization effect and reduces the risk of disinfection blind spots caused by insufficient light.

[0051] Reference Figure 4 and Figure 5 As shown, the storage mechanism 300 includes a storage box 310, a box cover 370 and a storage assembly.

[0052] The storage box 310 is fixedly mounted on a side wall of the bed body 110 in the length direction, and its position is symmetrical with the storage box 210, so that the user can efficiently recycle the used sheets when changing the sheets. This layout not only optimizes the space utilization, but also improves the convenience of operation, making the whole process smoother.

[0053] A storage cavity 301 for accommodating rolled sheets is provided inside the storage box 310, and a sheet outlet connected to the storage cavity 301 is provided on the side wall at one end in the width direction of the storage box 310, so that users can place or take out rolled sheets conveniently. An inlet 302 connected to the storage cavity 301 is provided on the top surface of the storage box 310, and its length is precisely matched with the length of the bed body 110 to ensure that the sheets can smoothly enter the storage cavity 301, and the end of the sheets extends into the storage cavity 301 through the inlet 302. The design of the inlet 302 ensures the smooth storage of sheets and avoids the inconvenience of operation or the risk of damage caused by size mismatch.

[0054] The box cover 370 is detachably buckled at the outlet of the storage box 310 and is made of easy-to-clean materials for easy daily maintenance and cleaning. The box cover 370 not only prevents dust and other pollutants from entering the storage cavity 301, but also protects the sheets inside from external pollution.

[0055] The storage assembly includes a motor 360 fixedly connected to the outer side wall of the storage box 310 in the width direction and a transmission shaft 350 coaxially fixedly connected to the output shaft of the motor 360 .

[0056] The output end of the motor 360 extends from the side wall of the storage box 310 into the storage cavity 301, and the transmission shaft 350 is rotatably arranged in the storage cavity 301, and the length direction of the transmission shaft 350 extends along the length direction of the storage box 310. This design not only ensures the stability of the structure, but also improves the transmission efficiency. The transmission shaft 350 driven by the motor 360 can run smoothly, providing reliable power support for the automatic winding of the bed sheet, and effectively improving the convenience of operation and work efficiency.

[0057] During use, the user only needs to pass the rolled sheet tube with adhesive on the outer side onto the transmission shaft 350 , and then the transmission shaft 350 can roll up the sheet neatly onto the sheet tube under the drive of the motor 360 .

[0058] The winding assembly further includes an electromagnetic slide rail 320 , an electromagnetic slider 330 and a push plate 340 .

[0059] The electromagnetic slide rail 320 is fixedly connected to the inner wall of the storage box 310, and the length direction of the electromagnetic slide rail 320 extends along the length direction of the storage box 310. The electromagnetic slide rod is arranged at the corner of the storage box 310 close to the bed body 110 to maximize the use of the space of the storage cavity 301 to store more sheets. The rationally arranged electromagnetic slide rail 320 optimizes the space utilization, so that the entire system can accommodate as many sheets as possible in a limited space, thereby improving the overall performance of the device.

[0060] The electromagnetic slider 330 is slidably disposed on the electromagnetic slider 330, and the push plate 340 is fixedly connected to the electromagnetic slider 330, and is driven by the electromagnetic slider 330 to slide back and forth along the length direction of the storage chamber 301. A through hole is provided in the center of the push plate 340 for the transmission shaft 350 to pass through, allowing it to slide back and forth along the length direction of the storage chamber 301 driven by the electromagnetic slider 330.

[0061] When the bed sheet needs to be rolled up, the push plate 340 is located on the side close to the motor 360; and when the bed sheet is stored, the electromagnetic slide rail 320 and the electromagnetic slider 330 work together to push the push plate 340 to move toward the sheet outlet, thereby pushing the rolled-up bed sheet tube out of the storage cavity 301. The combination of the electromagnetically driven slide rail and the slider 240 not only realizes precise position control, but also ensures the smoothness and reliability of the pushing action, greatly simplifying the process of taking out the bed sheet.

[0062] The control system includes a controller and a pressure sensor 120 fixedly installed on the surface of the bed 110 . The controller is electrically connected to the motor 360 , the electromagnetic slider 330 , the electromagnetic slide rail 320 and the pressure sensor 120 , respectively.

[0063] The main function of the pressure sensor 120 is to monitor the pressure on the bed 110 and feed back the collected data to the controller in real time.

[0064] First, a preset value is set in the controller, and during use, the controller makes a comparison based on the signal fed back by the pressure sensor 120 .

[0065] During the operation of the system, when the user lies on the mattress, the pressure sensor 120 fixedly mounted on the surface of the bed 110 begins to monitor the pressure of the bed 110 in real time. These pressure data are quickly transmitted to the controller for analysis and processing.

[0066] When the pressure value detected by the pressure sensor 120 is continuously higher than the preset value, it indicates that the user may need to change the bed sheet, and the controller enters the pre-start state.

[0067] The pressure value decreases rapidly and is lower than the preset value, and the controller responds immediately, activating the motor to rotate 360 ​​degrees to change the bed sheet. This process does not require manual intervention, which greatly facilitates the user's life.

[0068] In addition, the user can also control the movement of the electromagnetic slide rail 320 and the electromagnetic slider 330 by adjusting the controller, so that the push plate 340 moves along the length direction of the storage cavity 301, thereby effectively pushing the rolled bed sheet tube on the transmission shaft 350 out of the sheet outlet.

[0069] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
