Description

Technical Field

[0001] This utility model relates to the field of ultrasonic medical equipment technology, specifically to an ultrasonic medical examination bed. Background Technology

[0002] Ultrasound medicine studies the effects of ultrasound on the human body and its clinical applications from a medical perspective. It involves the physiological effects of ultrasound, instruments and equipment, clinical applications, and related theories and technologies. Ultrasound workstations support various models of color and black-and-white ultrasound equipment. They are fully functional, integrating patient registration, image acquisition, diagnostic editing, report printing, image post-processing, medical record retrieval, statistical analysis, and other functional modules, making them a powerful assistant for the scientific management of ultrasound departments.

[0003] Currently, when patients undergo ultrasound examinations in hospitals, they generally need to lie on the examination bed. To maintain hygiene and avoid cross-infection, medical staff need to change the sheets promptly. Common sheet-changing mechanisms currently use motor-driven rollers to collect and roll up the used portion of the sheet, which in turn drives the roller for rolling up the new sheet to release it, thus completing the sheet change. In current sheet-changing mechanisms, the roller for rolling up the sheet is typically connected to the bed frame via a bearing seat. When the sheet is fully rolled up and needs to be changed, the bearing seat needs to be disassembled to remove the roller, which is inconvenient and time-consuming. Furthermore, the roller for rolling up the new sheet is simply placed in the bed frame without a fixing mechanism. This causes the sheet roll in the bed frame to easily slip during the rolling process, resulting in the sheet on the bed being tilted, requiring frequent adjustments and significantly impacting subsequent use.

[0004] Currently, the common practice in hospitals is to lay a non-woven fabric on the bed sheet. Generally, medical staff need to replace this fabric after each patient's examination. This process is time-consuming, physically demanding, and increases the workload for medical staff. It also prolongs ultrasound examination time and reduces efficiency. The single-sided use of the non-woven fabric also results in some waste. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an ultrasound medical examination bed that can automatically change the bed sheet and disinfect and sterilize it during the recycling process, thereby reducing the workload of medical staff and improving the efficiency of ultrasound examinations.

[0006] This utility model is achieved through the following technical solution:

[0007] An ultrasound medical examination bed is provided, including a bed frame with a cavity below the bed surface. A headrest cabinet with a top opening is connected to the head of the bed frame, and a cover plate for mounting the headrest is hinged thereto. A headrest roller is rotatably mounted on the top of the headrest cabinet away from the bed frame, and a notch I for a sheet to pass through is provided below the headrest roller. An upper headrest roller, opposite the headrest roller, is rotatably mounted above the tail of the bed frame, and a lower headrest roller is rotatably mounted below the upper headrest roller. A notch II for a sheet to pass through is provided in the cavity of the bed frame corresponding to the lower headrest roller. The cavity of the bed frame contains... Ultraviolet lamps are installed above and below the bed sheet along the length of the bed frame. Tensioning rollers that slid up and down between the two side walls along the length of the bed frame are installed inside the cavity of the bed frame to abut against the bed sheet. The two ends of the tensioning rollers are connected to the bottom surface of the cavity through a tensioning mechanism. The bottom wall of the bed pillow cabinet is in the shape of two steps. A retraction roller is rotatably installed on the lower step of the bed pillow cabinet, and a motor for driving the rotation of the retraction roller is installed on one side of the bed pillow cabinet. A support roller for rolling up the bed sheet is rotatably installed on the upper second step of the bed pillow cabinet.

[0008] This solution, by designing a cavity in the bed frame and installing ultraviolet lamps on the inner wall of the cavity, can disinfect and sterilize both sides of the bed sheet during the bed sheet recycling process, ensuring the cleanliness of the bed sheet. After the recycling roller is full of bed sheets and the support roller is exhausted, the two rollers can be removed and their positions swapped, so that the other side of the bed sheet can be laid on the bed frame surface, realizing the double-sided use of the bed sheet and reducing waste.

[0009] Furthermore, the mandrels at both ends of the recovery roller and the mandrels at both ends of the support roller are respectively connected to the bearings by snap rings. The inner wall of the bed pillow cabinet is provided with mounting plates corresponding to the two ends of the recovery roller and the support roller, respectively. The side of the mounting plate facing the two ends of the roller is connected to the mounting seat. The surface of the mounting seat is recessed to form a mandrel groove for accommodating the mandrel and a positioning ring groove for positioning and accommodating the bearing. The mounting seat is hinged to the end cap for covering the mandrel and the bearing.

[0010] The mandrels at both ends of the recovery roller and support roller are connected to the bearings by snap rings. By snapping the bearings into the positioning ring grooves in the mounting seats on both sides of the mounting plate, when replacing or installing the roller body, you only need to open the end cover and lift the recovery roller and support roller directly to take them out from the bed pillow cabinet. It is simple, quick and convenient for replacement and installation.

[0011] Furthermore, the inner wall of the bed pillow cabinet has vertical guide rails installed above both ends of the recycling roller. The back of the mounting plate at both ends of the recycling roller is equipped with a sliding seat that slides with the guide rail. Cylinders are installed at the openings on both sides of the bed pillow cabinet, and the piston rods of the cylinders are connected downwards to the upper end of the mounting plate.

[0012] By installing guide rails on the inner wall of the bed and pillow cabinet, which slide in conjunction with the slide block on the back of the mounting plate, the cylinder can drive the mounting plate and the recycling roller between the two mounting plates to lift up and down, making it easy to lift the recycling roller full of bed sheets for easy replacement.

[0013] Furthermore, the two ends of the tension roller are connected to sliders, and the inner wall of the cavity of the bed is vertically formed with limiting grooves for accommodating the sliders and guiding their sliding.

[0014] The mandrels at both ends of the tensioning roller are slidably engaged with the limiting grooves on both sides of the inner wall of the bed cavity by setting sliders, which provide auxiliary limiting when the tensioning roller is tensioned up and down.

[0015] Furthermore, the tensioning mechanism includes bearing seats rotatably mounted on the mandrels at both ends of the tensioning roller. Each bearing seat has a guide rod vertically connected to its bottom surface facing downwards. The bottom surface of the bed cavity has a guide opening that mates with the guide rod. A compressed support spring is fitted on the guide rod between the bottom surface of the bed cavity and the bearing seat.

[0016] The tensioning mechanism uses bearing seats installed on the spindles at both ends, along with the guide rod and support spring below, to tighten the bed sheet using the elastic force of the support spring. The elastic deformation of the support spring can adapt to the overall tightness of the bed sheet, thus achieving automatic tensioning.

[0017] The beneficial effects of this utility model are:

[0018] In use, this invention involves winding the bed sheet around the headboard roller via a support roller, then through the upper and lower footboard rollers, into the bed cavity. Tensioned by a tension roller, it is then wound onto a recovery roller. A drive motor rotates the recovery roller to roll up the sheet. After a patient's use, the used sheet can be rolled up and replaced with a new, unused sheet, allowing for manual sheet replacement and reducing the workload of medical staff. After passing through the bed cavity, the used sheet is disinfected by ultraviolet light, improving its cleanliness. The disinfected sheet is then collected on the recovery roller. By swapping the recovery roller and support roller in the bed frame, the other side of the sheet can be laid on the bed for continued use, achieving double-sided utilization and reducing waste.

[0019] During use, the collection roller collects a full load of sheets. After the sheets on the support roller are used up, the collection roller and support roller can be lifted and removed by opening the end cover on the mounting base for replacement or swapping. Installation and disassembly are convenient, improving ease of use. Attached Figure Description

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0028] like Figure 1-Figure 5As shown, an ultrasound medical examination bed includes a bed body 1. A cavity 2 is provided below the bed surface of the bed body 1. A headrest cabinet 3 with a top opening is connected to the head of the bed body 1, and a cover plate 4 for installing a headrest is hinged thereto. A headrest roller 5 is rotatably mounted on the top of the headrest cabinet 3 away from the bed body 1, and a notch 16 for a bed sheet 14 to pass through is provided below the headrest roller 5. An upper headrest roller 7, directly opposite the headrest roller 5, is rotatably mounted above the tail of the bed body 1, and a lower headrest roller 8 is rotatably mounted below the upper headrest roller 7. The cavity 2 of the bed body 1 has an opening corresponding to the lower headrest roller 8 for the bed sheet 14 to pass through. Through the notch II9 of the single sheet 14, ultraviolet lamps 10 are installed above and below the sheet 14 along the length of the bed body 1 in the cavity 2. Tensioning rollers 11, which abut against the sheet 14, are slidably installed between the two side walls of the bed body 1 along the length of the bed body 1 in the cavity 2. The two ends of the tensioning rollers 11 are connected to the bottom surface of the cavity 2 through a tensioning mechanism. The two end spindles of the tensioning rollers 11 are respectively connected to sliders 15. The inner wall of the cavity 2 of the bed body 1 has vertically formed limiting grooves 16 for accommodating the sliders 15 and guiding their sliding. The tensioning mechanism includes bearing seats 17 rotatably mounted on the spindles at both ends of the tensioning rollers 11. Each bearing seat 17 has a guide rod 18 vertically connected to the bottom surface of the bottom surface of the bed body 1, facing the guide rod 18. A guide opening that cooperates with the guide rod 18 is opened on the bottom surface of the cavity 2 of the bed body 1, between the bottom surface of the bed body cavity 2 and the bearing seat 17, and a compressed support spring 19 is sleeved on the guide rod 18.

[0029] The inner bottom wall of the bed pillow cabinet 3 is shaped like two steps. A retraction roller 12 is rotatably mounted on the lower step of the inner wall of the bed pillow cabinet 3. A motor 20 for driving the rotation of the retraction roller 12 is installed on one side of the bed pillow cabinet 3. A button for controlling the motor 20 is installed on the side of the bed body 1. A support roller 13 for rolling up the bed sheet 14 is rotatably mounted on the upper second step of the inner wall of the bed pillow cabinet 3. In order to facilitate the motor 20 to drive the retraction roller 12 and facilitate the loading and unloading of the retraction roller 12, the two can be driven by gears. A drive gear 30 is installed on the main shaft of the motor 20. A driven gear 25 is provided on the spindle of the retraction roller 12 on the side corresponding to the motor 20, which can mesh with the drive gear 30. When the retraction roller 12 is placed on the first step, the driven gear 25 meshes with the drive gear 30 below. By starting the motor 20, the motor 20 and the gear can drive the retraction roller 12 to rotate and roll up the bed sheet 14.

[0030] like Figure 5As shown, the mandrels at both ends of the recovery roller 12 and the mandrels at both ends of the support roller 13 are respectively connected to the bearings 21 by snap rings. The inner wall of the bed pillow cabinet 3 is provided with mounting plates 22 corresponding to the two ends of the recovery roller 12 and the support roller 13. The side of the mounting plate 22 facing the two ends of the rollers is connected to the mounting seat 23. The surface of the mounting seat 23 is recessed to form a mandrel groove for accommodating the mandrel and a positioning ring groove 24 for positioning and accommodating the bearing 21. The mounting seat 23 is hinged to the end cap 29 for covering the mandrel and the bearing 21.

[0031] To facilitate the removal of the collection roller 12 from the bed pillow cabinet 3 after collecting the bed sheet 14, guide rails 26 are vertically installed above both ends of the collection roller 12 on the inner wall of the bed pillow cabinet 3. Slide seats 27 that slide in cooperation with the guide rails 26 are installed on the back of the mounting plates 22 at both ends of the collection roller 12. Cylinders 28 are installed at the openings on both sides of the bed pillow cabinet 3. The piston rod of the cylinder 28 is connected downward to the upper end of the mounting plate 22.

[0032] In use, the recycling roller 12 and the support roller 13 with the sheet 14 rolled up are placed on the first and second steps inside the bed and pillow cabinet 3, respectively. Then, the sheet 14 is led out through the notch I6 and wound around the headboard roller 5. After passing the bed surface, it is guided by the upper headboard roller 7 and the lower headboard roller 8 and enters the cavity 2 through the notch II9. Then it is wound around the recycling roller 12. After the patient has used the bed surface, the motor 20 is controlled by the operation control button to rotate. After the recycling roller 12 rotates a fixed number of times, the used sheet 14 on the bed surface can be collected on the recycling roller 12 and the support roller 13 is driven to rotate passively to lay the new unused sheet 14 on the bed surface, thus completing the sheet replacement.

[0033] During the bed sheet changing process, after the used bed sheet enters the cavity 2, the upper and lower surfaces of the bed sheet 14 can be disinfected and sterilized by the ultraviolet lamps 10 installed at the top and bottom of the cavity 2, thereby improving the cleanliness of the bed sheet 14. As the support roller 13 rotates, after the bed sheet 14 on the support roller 13 is consumed, the bed sheet 14 on the recycling roller 12 is also full. The recycling roller 12 and the support roller 13 can be lifted directly out of the bed pillow cabinet 3 by opening the cover plate 4 and the end cover 29 respectively, for replacement. Of course, the positions of the support roller 13 and the recycling roller 12 can also be swapped, so that the bed sheet 14 can be used on both sides, reducing waste. Because the first step inside the bed pillow cabinet 3 is quite deep, and the weight increases after being fully wrapped with bed sheets 14, making it inconvenient to remove, the piston rod of the cylinder 28 can be used to pull the mounting plate 22 to lift the recycling roller 12 to the first step, which makes it easier to remove the recycling roller 12 and improves the convenience of operation.

[0034] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
