Description

Technical Field

[0001] This utility model relates to the field of medical bed technology, and in particular to a medical bed with an easily replaceable inner liner. Background Technology

[0002] Examination beds, as essential equipment in hospitals and various medical institutions, are widely used in the diagnosis, treatment, nursing, and examination of patients. To maintain the cleanliness and hygiene of examination beds, a quilt is usually laid on their surface. These quilts are mostly made of non-woven fabric, but disposable paper sheets can also be used. During use, the quilt comes into direct contact with the patient's skin and clothing, easily absorbing sweat, secretions, and bodily fluids. Since some patients may carry different pathogens (such as multidrug-resistant bacteria and viruses), the quilt can become a potential medium for pathogen transmission. Timely changing of the quilt between different patients is a crucial measure to block pathogen transmission and prevent cross-infection, especially helpful in ensuring patient safety, particularly for patients with weakened immune systems (such as postoperative patients, the elderly, and critically ill patients), where cross-infection can lead to serious consequences. Therefore, timely changing of the quilt is of paramount importance in reducing the risk of infection and ensuring medical safety.

[0003] Most existing treatment beds rely on manual sheet changing. Medical staff must first remove the old sheets and then place the new sheets on the bed board or mattress one by one. This method is cumbersome and inefficient, especially in high-volume scenarios such as large patient flow or emergency rooms, where timely sheet changing is often difficult. This not only affects the continuity and efficiency of medical work but may also reduce patient safety and comfort.

[0004] To address the time-consuming and labor-intensive issue of manual sheet changing, some medical institutions have adopted roll-up sheet changing devices. However, these devices typically employ a simple winding and rolling mechanism, making it easy for the sheets to fold or shift during the pulling and rolling process. This results in uneven laying and even loose rolling, affecting the sheets' tightness and usability. Furthermore, most existing devices do not effectively protect the sides of the bed frame or mattress, causing the sheets to easily curl up or come off, reducing the hygiene and aesthetics of the treatment bed.

[0005] For example, a treatment bed described in patent publication number CN102579216A; although the above technical solution can achieve quick replacement of bed sheets, the above technical solution may result in the old bed sheets being folded during storage, and the above technical solution does not describe effective protection for the sides of the bed board or mattress.

[0006] In view of the above problems, this utility model provides a treatment bed that facilitates the changing of the bed sheet and allows the sides of the bed sheet to be folded at a certain angle for easy changing of the middle sheet. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a treatment bed with an easy-to-change drape.

[0008] The purpose of this utility model is achieved as follows: a treatment bed with easy-to-change sheets, including a support frame, on which a bed board is provided (a mattress or other material can be placed on the bed board as needed, and a sheet can be laid on the mattress; the specific structure depends on the situation). A roller shaft one is rotatably provided on the lower front side of the bed board, and a rotating roller and a roller shaft two are rotatably provided on the lower rear side of the bed board. The roller shaft two is located below the rotating roller, and a pressure roller is provided between the rotating roller and the roller shaft two. The sheet is wrapped around the roller shaft one, then laid on top of the bed board, passing over the rotating roller, then over the pressure roller, and collected by the roller shaft two. The sheet is existing technology and can be a paper sheet or a non-woven sheet, etc., without technical limitations; the length of the sheet is less than or equal to the length of the roller shaft one, the roller shaft two, and the rotating roller, and the width of the sheet is greater than the width of the bed board.

[0009] Furthermore, a housing is provided on both the left and right sides of the roller shaft, and the housing is fixedly connected to the bed board; the roller shaft is rotatably connected to the housing, and a strip hole is opened on the upper end face of the housing, through which the bed sheet passes.

[0010] Furthermore, one end of the pressure roller is connected to a transmission rod, and the pressure roller is rotatably located at one end of the transmission rod. The other end of the transmission rod is rotatably mounted on the housing two. A spring is provided in the middle of the upper surface of the transmission rod, and the other end of the spring is connected to the housing two. The length of the pressure roller is greater than or equal to the width of the bed sheet. A connecting ring is connected to the upper end of the spring, and the connecting ring is rotatably located on a rotating shaft. The rotating shaft is fixed on the housing two, and the spring is in a compressed state during use.

[0011] In use, the sheet is wound around roller one. The controller controls the drive mechanism to rotate roller two. Roller two pulls the sheet to move and rewind, which in turn drives roller one to rotate, pulling the sheet out. At this time, the sheet first passes through the rotating roller, and the guide plate above the rotating roller flattens the sheet so that roller two can rewind the sheet. A pressure roller is provided to tighten the sheet between roller two and the rotating roller, preventing looseness that would cause the sheet to be rolled up too loosely when roller two rewinds the sheet. That is, when the sheet between the two is too loose, the spring force drives the rotating rod to rotate, causing the pressure roller to move towards the sheet, thus tightening the sheet.

[0012] After the new bed sheet is laid on the bed board, the controller stops the drive mechanism from rotating and simultaneously controls the lifting mechanism to move downwards, causing the pressure rod to move downwards. When the pressure rod moves downwards, it causes the bed sheet on the side of the bed board to fold downwards, thereby achieving a certain degree of downward bending of the bed sheet to protect the side of the bed board or mattress.

[0013] Beneficial effects: This utility model has the following technical effects when used:

[0014] 1. By installing roller one, rotating roller, pressure roller, and roller two under the treatment bed board, a structure is formed that can automatically pull out and roll up the bed sheet, making the process of laying and changing the bed sheet more efficient and convenient. Medical staff no longer need to manually change the bed sheet repeatedly; they only need to drive roller two to rotate via a drive mechanism to achieve automatic pulling out and rolling up of the bed sheet, significantly reducing labor intensity and improving the utilization efficiency of the treatment bed.

[0015] 2. Equipped with a guide plate and its arc-shaped structure, it can flatten and limit the sheet during movement, preventing the sheet from folding or shifting in the middle, and facilitating the even winding of the sheet by the two rollers.

[0016] 3. By adding a pressure roller between roller shaft two and the rotating roller, and in conjunction with a spring and transmission rod structure, the bed sheet can be automatically tensioned. When the bed sheet becomes loose during movement or rolling, the pressure roller automatically closes to the bed sheet under the action of the spring, achieving a tightening effect, avoiding wrinkles or looseness during rolling, and improving the tightness and neatness of the roll.

[0017] 4. Both housing one and housing two are equipped with vertically movable pressure rods, which work in conjunction with the lifting mechanism. After the bed sheet is laid out, the pressure rods can fold the two sides of the bed sheet downwards, thereby wrapping and protecting the sides of the bed board or mattress. This not only improves the fixation of the bed sheet, but also enhances the protective performance of the bed board sides, thus improving the patient's user experience. Attached Figure Description

[0024] Example 1, as Figure 1-4 As shown, the purpose of this utility model is achieved as follows: a treatment bed that facilitates changing the bed sheet includes a support 1, on which a bed board 4 is provided (a mattress or other material can be placed on the bed board 4 as needed, and a bed sheet 3 is laid on the mattress; the specific structure depends on the situation); a roller 8 is rotatably provided on the lower front side of the bed board 4, and a rotating roller 13 and a roller 5 are rotatably provided on the lower rear side of the bed board 4. The roller 5 is located below the rotating roller 13, and a pressure roller 11 is provided between the rotating roller 13 and the roller 5. The bed sheet 3 is wrapped around the roller 8, then laid on top of the bed board 4, passing over the rotating roller 13, then over the pressure roller 11, and collected by the roller 5. The bed sheet 3 is existing technology and can be a paper bed sheet 3 or a cloth bed sheet 3, etc., without technical limitations; the length of the bed sheet 3 is less than or equal to the length of the roller 8, the roller 5, and the rotating roller 13, and the length of the bed sheet 3 is greater than the width of the bed board 4.

[0025] Roller shaft 8 has housings 7 on both sides, which are fixedly connected to the bed board 4. Roller shaft 8 is rotatably connected to housing 7. A slotted hole 1 is provided on the upper surface of housing 7, through which the bed sheet 3 passes. Roller shaft 5 has housings 2 on both sides, which are fixedly connected to the bed board 4. Roller shaft 5 is rotatably connected to housing 2. A slotted hole 2 is provided on the upper surface of housing 2, through which the bed sheet 3 passes. Pressure rods 6 are provided on both housing 7 and housing 2, which can move up and down.

[0026] The pressure rod 6 has an L-shaped structure, with an arc-shaped inner side at its lower end. Located above the bed sheet 3, the pressure rod 6 moves up and down, causing the bed sheets 3 on both sides of the bed board 4 to fold downwards. This helps to bend the bed sheets 3 on both sides of the bed board 4 downwards, protecting the sides of the bed board 4 (or mattress). A lifting mechanism 18 is installed at the lower end of the pressure rod 6. The lifting mechanism 18 is fixed to the corresponding housing 7 and housing 2. The lifting mechanism 18 moves the pressure rod 6 up and down. The output end of the lifting mechanism 18 is located outside the bed sheet 3, preventing interference with the bed sheet 3 when it moves the pressure rod 6 up and down.

[0027] A drive mechanism 17 is provided inside the housing 2. The drive mechanism 17 drives the roller 2 5 to rotate. (The drive mechanism 17 can drive the roller 2 5 to rotate and can also control its start and stop; for example, it can be a motor, etc., without technical limitations and is existing technology).

[0028] A guide plate 14 is provided above the rotating roller 13, and a connecting rod 15 is provided on the guide plate 14. The guide plate 14 is fixedly connected to the bed board 4 through the connecting rod 15. The upper end surface of the guide plate 14 is an upwardly convex arc-shaped structure. When the bed sheet 3 moves downward, it can prevent the bed sheet 3 from first contacting the middle of the arc-shaped structure, thus preventing the bed sheet 3 from folding or shifting in the middle, so that the bed sheet 3 can open to both sides, which is conducive to the roller shaft 5 storing it.

[0029] One end of the pressure roller 11 is connected to a transmission rod 12. The pressure roller 11 is rotatably located at one end of the transmission rod 12, and the other end of the transmission rod 12 is rotatably mounted on the housing 2. A spring 10 is provided in the middle of the upper surface of the transmission rod 12, and the other end of the spring 10 is connected to the housing 2. The length of the pressure roller 11 is greater than or equal to the width of the bed sheet 3. A connecting ring 16 is connected to the upper end of the spring 10. The connecting ring 16 is rotatably located on the rotating shaft 9, and the rotating shaft 9 is fixed on the housing 2. The spring 10 is under pressure during use.

[0030] In use, the sheet 3 is wound around roller 8. The controller controls the drive mechanism 17 to drive roller 5 to rotate. Roller 5 pulls the sheet 3 to move and roll it up, which in turn drives roller 8 to rotate, pulling the sheet 3 out. At this time, the sheet 3 first passes through the rotating roller 13. The guide plate 14 above the rotating roller 13 flattens the sheet 3 so that roller 5 can roll it up. The pressure roller 11 can tighten the sheet 3 between roller 5 and rotating roller 13 to prevent loosening and the sheet 3 from being rolled up loosely by roller 5. That is, when the sheet 3 between the two is loose, the elastic force of the spring 10 drives the rotating rod to rotate, so that the pressure roller 11 moves towards the sheet 3, thereby tightening the sheet 3.

[0031] After the new bed sheet 3 is laid on the bed board 4, the controller controls the drive mechanism 17 to stop rotating and at the same time controls the lifting mechanism 18 to move downward, so that the pressure rod 6 moves downward. When the pressure rod 6 moves downward, it drives the bed sheet 3 on the side of the bed board 4 to fold downward, thereby achieving a certain degree of bending of the bed sheet 3 downward to protect the side of the bed board 4 or the mattress.
