Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a modular electric hospital bed with rehabilitation effect. Background Art

[0002] In order to meet the postoperative needs of patients, hospital beds usually have functions such as body position adjustment, installation of protection, and hygiene management to facilitate the daily nursing work of medical staff or caregivers for patients.

[0003] For some patients, such as orthopedic patients or stroke patients, etc., who need hand rehabilitation training after surgery, there are usually two traditional methods: one is to transfer the patient to a special rehabilitation training instrument in a trolley. This method involves the movement and transfer process of the patient. Medical staff need to carefully lift the patient onto the trolley first, then push it to the designated rehabilitation training area, and then transfer the patient from the trolley to the rehabilitation training instrument; the other method is to push the rehabilitation equipment and temporarily place it beside the bed for the patient to use. This requires moving a relatively large rehabilitation equipment and ensuring that the equipment is firmly placed beside the bed, and the operation is also rather troublesome.

[0004] Regarding the above related technologies, the use processes of these rehabilitation training methods are all rather inconvenient, which not only increases the workload of medical staff, but also may bring physical discomfort and psychological pressure to patients, and is not conducive to the smooth progress of patients' rehabilitation training. Summary of the Invention

[0005] In order to facilitate patients to perform rehabilitation on the hospital bed, this application provides a modular electric hospital bed with rehabilitation effect.

[0006] This application provides a modular electric hospital bed with rehabilitation effect, adopting the following technical solutions: A modular electric hospital bed with rehabilitation effect includes a bed frame and guardrails arranged on both sides of the bed frame. The guardrails include a guardrail body and an armrest seat. The armrest seat is detachably arranged on the side of the guardrail body close to the head of the bed, and a hand-held cavity for the patient to hold the armrest seat is formed on the armrest seat. An installation seat is slidably arranged on the side of the guardrail body facing the inner side of the hospital bed. The installation seat is detachably fixed on the installation seat. A movement chute for the installation seat to slide is formed on the inner side wall of the guardrail body. A driving device for driving the installation seat to slide is arranged inside the guardrail body, and the driving device can drive the installation seat to reciprocate along the movement chute. The movement chute includes a first section chute, a second section chute, and a third section chute that are sequentially connected to each other. The first section chute extends along the horizontal direction, the second section chute extends along the vertical direction, and the lower end of the second section chute communicates with the end of the first section chute away from the head of the bed. The upper end of the third section chute communicates with the upper end of the second section chute, and the lower end of the third section chute communicates with the end of the first section chute close to the head of the bed. The first section chute, the second section chute, and the third section chute are all connected by an arc-shaped chute.

[0007] By adopting the above technical solution, the electric hospital bed is provided with a detachable armrest seat with a hand-holding cavity, which is convenient for patients to hold; the driving device drives the mounting seat to reciprocate along each section of the movement chute, which can help patients achieve rehabilitation exercises and improve the rehabilitation effect; when the mounting seat reciprocates horizontally in the first section chute, the patient's arm straightens and bends with the reciprocating movement of the armrest seat, which can exercise the elbow joint; when the mounting seat reciprocates up and down in the second section chute, the patient's arm is straightened and rises and falls with the armrest seat, which can exercise the shoulder joint; when the mounting seat moves repeatedly in the third section chute, the elbow joint and the shoulder joint can be exercised simultaneously.

[0008] Optionally, the driving device includes a sprocket, a chain, a driving shaft, and a power source. A driving chute for the chain to slide circumferentially is provided in the guardrail body, and the extending direction of the driving chute corresponds to the extending direction of the movement chute; the sprocket is rotatably arranged in the guardrail body, the sprocket meshes with the chain, the power source is used to drive the sprocket to rotate, one end of the driving shaft is connected to the chain, and the other end of the driving shaft is connected to the mounting seat.

[0009] By adopting the above technical solution, the driving device composed of a sprocket, a chain, a driving shaft, and a power source, in cooperation with the driving chute whose extending direction corresponds to the movement chute, enables the power source to drive the sprocket to rotate and drive the chain to slide circumferentially, and further enables the driving shaft connected to the chain to drive the mounting seat to reciprocate along the movement chute, which helps the mounting seat and the fixed armrest seat to move along a preset path and assist patients in rehabilitation training.

[0010] Optionally, three sprockets are provided, and the three sprockets are respectively arranged at the arc-shaped connection parts of the first section chute, the second section chute, and the third section chute.

[0011] By adopting the above technical solution, the chain can stably slide circumferentially around the movement chute composed of the first section chute, the second section chute, and the third section chute, ensuring that the driving device can accurately drive the mounting seat to reciprocate along the movement chute and enabling the armrest seat to achieve precise displacement to assist patients in rehabilitation.

[0012] Optionally, a limiting groove is circumferentially formed on the side wall of the mounting base, and circumferential positioning strips are respectively arranged on the side walls of both sides of the movement sliding groove of the guardrail body. When the mounting base slides along the movement sliding groove, the positioning strips are clamped in the limiting groove.

[0013] By adopting the above technical solution, a limiting groove is formed on the side wall of the mounting base, and circumferential positioning strips are arranged on both sides of the movement sliding groove of the guardrail body. The positioning strips are inserted into the limiting groove, so that when the mounting base slides along the movement sliding groove, it is more stable, reducing shaking and deviation, improving the accuracy of the movement of the mounting base, and enhancing the reliability and safety of the use of the handrail base.

[0014] Optionally, two connecting columns are arranged at intervals along the vertical direction on the side wall of the handrail base facing the guardrail body. The guardrail body is provided with a first connecting groove for inserting the connecting columns on the side facing the head of the bed, and a first fixing member for fixing the connecting columns in the first connecting groove. A rotating ring is rotatably arranged on the side of the mounting base facing the inner side of the hospital bed. A second connecting groove for inserting the connecting columns is formed on the rotating ring, and a second fixing member for fixing the connecting columns in the second connecting groove is provided. Two groups of the first fixing member and the second fixing member are respectively arranged corresponding to the two connecting columns.

[0015] By adopting the above technical solution, the handrail base of the hospital bed can be inserted into the first connecting groove of the guardrail body and the second connecting groove of the rotating ring through the connecting columns, and is respectively fixed by the first fixing member and the second fixing member, realizing the reliable connection of the handrail base with the guardrail body and the rotating ring of the mounting base. At the same time, since the rotating ring of the mounting base can rotate, it is convenient to adjust the angle of the handrail base, improving the comfort of the patient during use.

[0016] Optionally, the second fixing member includes a fixing arc rod, a first spring and a control grip. An arc-shaped groove for the fixing arc rod to slide is formed in the rotating ring. One end of the arc-shaped groove is communicated with the second connecting groove. The first spring is arranged in the arc-shaped groove and is located at the end of the fixing arc rod away from the second connecting groove. An arc-shaped connecting hole is formed in the connecting column. A positioning groove is formed on the side of the second connecting groove away from the arc-shaped groove. When the connecting column is inserted into the second connecting groove, the fixing arc rod can pass through the connecting hole and be inserted into the positioning groove. At this time, the first spring is in a compressed state; the control grip is arranged on the side wall of the fixing arc rod, and the end extends out of the rotating ring. An arc-shaped relief groove for the control grip to slide is formed on the rotating ring.

[0017] By adopting the above technical solution, the connecting column of the armrest seat is firmly inserted into the second connecting groove of the rotating ring under the cooperation of the fixed arc rod with the connecting hole and the positioning groove, ensuring the stability of the connection; and the position of the fixed arc rod can be conveniently controlled by using the spring and the control grip, realizing the quick installation and disassembly of the armrest seat on the rotating ring.

[0018] Optionally, a ring groove for the circumferential rotation of the rotating ring is formed in the mounting seat. A plurality of first positioning grooves are circumferentially formed on the bottom wall of the ring groove. At least two first positioning holes are spaced apart on the rotating ring. A plurality of positioning bolts are detachably arranged on the mounting seat. The positioning bolts can pass through the first positioning holes and be threadedly connected with the first positioning grooves.

[0019] By adopting the above technical solution, the rotating ring can be positioned at different positions by screwing the positioning bolts through the first positioning holes and connecting them with the first positioning grooves. When the positioning seat reciprocates in a certain section of the movement chute, the rotation of the rotating ring is restricted by the positioning bolts, thereby restricting the rotation of the armrest seat, which can improve the stability when the patient uses it.

[0020] Optionally, a pull ring, a stretching rope and a winding member are arranged in the armrest seat. A limiting member for restricting the sliding of the mounting seat is arranged at the upper end of the second section of the groove on the guardrail body. The pull ring is detachably embedded in the armrest seat. One end of the stretching rope is connected to the pull ring, and the other end is stored in the armrest seat through the winding member. The stretching rope has elasticity.

[0021] By adopting the above technical solution, the limiting member arranged at the upper end of the second section of the groove can restrict the sliding of the mounting seat. The pull ring arranged in the armrest seat and the elastic stretching rope cooperate with the winding member, enabling the patient to pull the pull ring for active rehabilitation training.

[0022] Optionally, the winding member includes a winding shaft, a winding roller, a coil spring and a positioning plug. The winding shaft is rotatably arranged in the armrest seat. The winding roller is coaxially fixed on the winding shaft. One end of the stretching rope away from the pull ring is fixed to the side wall of the winding roller. The coil spring is arranged in the armrest seat. The winding shaft is connected to the inner force-bearing end of the coil spring. The outer force-bearing end of the coil spring is fixed to the armrest seat. A second positioning groove is formed at the end of the winding roller. A third positioning groove is formed on the armrest seat. When the stretching rope is completely wound on the winding roller or pulled out of the winding roller, the second positioning groove is aligned with the third positioning groove, and the positioning plug can be inserted into both the second positioning groove and the third positioning groove simultaneously.

[0023] By adopting the above technical solution, it is ensured that the stretching rope can be stably positioned when being wound or pulled out, and the automatic winding function is realized in cooperation with the coil spring, improving the use convenience and the stretching operation experience.

[0024] Optionally, the limiting member is a limiting bolt. A limiting threaded groove is provided on the guardrail body, and a limiting hole for the limiting bolt to pass through is provided on the mounting seat. When the mounting seat slides to the upper end of the second section of the groove, the limiting hole can be aligned with the limiting threaded groove, and the limiting bolt can pass through the limiting hole and be threadedly connected to the limiting threaded groove. At least two limiting bolts are provided.

[0025] By adopting the above technical solution, it is possible to stably and reliably limit and fix the mounting seat when it slides to the upper end of the second section of the groove, ensure the stability of the position of the mounting seat, and thus improve the safety of the patient during active exercise.

[0026] In summary, the present application includes at least one of the following beneficial effects: 1. The armrest seat is detachably arranged and can reciprocally slide along the movement chute of a specific track under the action of the driving device with the mounting seat, which can improve the flexibility of the patient using the armrest and at the same time meet the patient's need for convenient passive rehabilitation training in the hospital bed; 2.

[0029] The following further elaborates on this application in conjunction with the attached Figure 1-8 drawings for a more detailed description.

[0030] Embodiment 1

[0031] The embodiment of this application discloses a modular electric hospital bed with a rehabilitation effect. Referring to Figure 1 , the electric hospital bed includes a bed frame 1 and guardrails arranged on both sides of the bed frame 1. Among them, the bed frame 1 plays a role in supporting the entire hospital bed, and the guardrails provide protection on the left and right sides for the patient, preventing the patient from accidentally rolling off the hospital bed and ensuring the safety of the patient.

[0032] Further, the guardrail further includes a guardrail body 2 and an armrest seat 3. The armrest seat 3 is detachably arranged on the side of the guardrail body 2 close to the head of the bed. A hand-holding cavity 31 for the patient to hold the armrest seat 3 is formed on the armrest seat 3. When the armrest seat 3 is fixed to the side of the guardrail body 2 close to the head of the bed, it provides support for the patient to hold, facilitating the patient with inconvenient body to borrow strength to get up or adjust the posture. A mounting seat 4 is slidably arranged on the side of the guardrail body 2 facing the inner side of the hospital bed. The armrest seat 3 is detachably fixed to the mounting seat 4. Thus, after the armrest seat 3 is detached from the guardrail body 2, it can be fixed to the mounting seat 4. A movement chute 21 for the mounting seat 4 to slide is formed on the inner side wall of the guardrail body 2. A driving device 5 for driving the mounting seat 4 to slide is arranged inside the guardrail body 2. The driving device 5 can drive the mounting seat 4 to reciprocally slide along the movement chute 21. This design enables the armrest seat 3 to be installed on the side of the guardrail body 2 facing the hospital bed and move together with the mounting seat 4, which can assist the patient with limited upper limb movement in passive rehabilitation training. When the armrest seat 3 moves, the patient's hand can follow its movement trajectory, thereby moderately exercising the hand joints and muscles. In addition, for patients with insufficient grip strength, the armrest seat 3 can be used in combination with straps or gloves to ensure that the hand is firmly fixed on the armrest seat 3 and avoid accidental slipping during the training process.

[0033] Referring to Figure 1 and Figure 2 , in the embodiment of the present application, the lower end of the guardrail body 2 can be detachably fixed to the bed frame 1 by means of bolts or the like. Optionally, a plurality of connecting seats 25 can be fixedly connected to the lower end of the guardrail body 2. A connecting plate 11 is also welded and fixed on the side wall of the bed frame 1 along its own length direction. A plurality of groups of threaded holes are arranged at intervals along the length direction of the connecting plate 11. Four openings can be circumferentially arranged on each connecting seat 25. Thus, by setting bolts to pass through the openings and threadedly connecting them to the threaded holes, the connecting seat 25 can be detachably fixed to the connecting plate 11, that is, the guardrail body 2 can be detachably fixed to the bed frame 1. At the same time, by setting a plurality of groups of threaded holes, the position of the guardrail body 2 can also be moved along the length direction of the bed frame 1, so that the position of the armrest seat 3 can be adjusted according to the arm lengths of different patients, improving the adaptability of the patient's use.

[0034] Referring to Figure 2 and Figure 3, in the embodiment of the present application, the movement chute 21 includes a first section chute 211, a second section chute 212, and a third section chute 213 that are sequentially connected to each other. The first section chute 211 extends along the horizontal direction, the second section chute 212 extends along the vertical direction, and the lower end of the second section chute 212 communicates with the end of the first section chute 211 away from the head of the bed. The upper end of the third section chute 213 communicates with the upper end of the second section chute 212, and the lower end of the third section chute 213 communicates with the end of the first section chute 211 close to the head of the bed. The third section chute 213 can be set as an inclined chute or an arc-shaped chute; the first section chute 211, the second section chute 212, and the third section chute 213 are all connected by arc-shaped chutes. The cross-section of the mounting seat 4 can be circular, so as to facilitate the movement of the mounting seat 4 along the movement chute 21.

[0035] Such a design makes the movement trajectory of the mounting seat 4 more diverse, and patients can perform rehabilitation training during movements in different directions. For example, when the mounting seat 4 reciprocally slides horizontally within the first section chute 211, the patient's arm straightens and bends as the armrest seat 3 reciprocally moves, which can exercise the elbow joint; when the mounting seat 4 reciprocally slides up and down within the second section chute 212, the patient's arm is straightened and moves up and down with the armrest seat 3, which can exercise the shoulder joint; when the mounting seat 4 repeatedly moves within the third section chute 213, the elbow joint and the shoulder joint can be exercised simultaneously.

[0036] Refer to Figure 3 and Figure 4 , the driving device 5 includes a sprocket 51, a chain 52, a driving shaft 53, and a power source 54. A driving chute 22 for the circumferential sliding of the chain 52 is provided within the guardrail body 2, and its extending direction corresponds to the extending direction of the movement chute 21. The sprocket 51 is rotatably arranged within the guardrail body 2 and meshes with the chain 52. The power source 54 is used to drive the rotation of the sprocket 51. The driving shaft 53 is connected between the mounting seat 4 and the chain 52. The rotation of the chain 52 drives the movement of the driving shaft 53, thereby realizing the sliding of the mounting seat 4 along the movement chute 21. Specifically, the surface of the sprocket 51 has evenly distributed teeth, and these teeth fit with the links of the chain 52 to ensure the stability and accuracy of the transmission. The sprocket 51 can be made of alloy steel material, which has high hardness, good wear resistance, and can withstand large torques without being easily damaged. The chain 52 is an ordinary transmission chain 52, and the links are tightly connected and can be flexibly bent to adapt to movement conversions in different directions. The power source 54 can be a motor, and its output shaft is coaxially connected to the sprocket 51. Optionally, a reduction device can also be configured to cooperate with the motor to precisely control the moving speed of the mounting seat 4; in order to facilitate the control of the movement of the armrest seat 3, an induction device can also be used in combination to precisely control the moving position of the mounting seat 4.

[0037] In an alternative embodiment, preferably three sprockets 51 are provided, which are respectively arranged at the arc-shaped joints of the first section of groove 211, the second section of groove 212, and the third section of groove 213, and each sprocket 51 fits with the link of the chain 52. Such a layout enables the chain 52 to rotate smoothly at each turning point, ensuring the efficient operation of the driving device 5. The power source 54 can be provided with three, or can be provided with one, and is used to control any one of the sprockets 51.

[0038] In other embodiments, the driving device 5 can also adopt the cooperation mode of a gear and a rack. For example, corresponding to the trajectory of the moving chute 21, a rack is circumferentially arranged inside the guardrail body 2, and then the power source 54 drives the gear to rotate, so that the gear can slide along the extending direction of the rack under the meshing with the rack. The mounting seat 4 is coaxially connected with the gear, and the mounting seat 4 can be driven to move by the movement of the gear.

[0039] Refer to Figure 3 and Figure 4 To ensure the stability of the movement of the mounting seat 4, a limiting groove 41 is circumferentially formed on the side wall of the mounting seat 4, and circumferential positioning strips 23 are respectively arranged on the side walls of both sides of the moving chute 21 of the guardrail body 2. When the mounting seat 4 slides along the moving chute 21, the positioning strips are clamped in the limiting groove 41 to prevent the mounting seat 4 from deviating from the movement track. The limiting groove 41 is an annular groove, and the positioning strip is a protruding long strip. The cooperation relationship between the two is like that of a track and a slider. The positioning strip can be made of alloy material, which has high strength and can maintain its shape unchanged for a long time.

[0040] Refer to Figure 3 and Figure 5 In the embodiment of the present application, two connecting columns 32 are fixedly arranged at intervals along the vertical direction on the side wall of the armrest seat 3 facing the guardrail body 2. The guardrail body 2 is provided with a first connecting groove 24 for inserting the connecting columns 32 on the side facing the head of the bed, and a first fixing member 6 for fixing the connecting columns 32 in the first connecting groove 24 is provided. The first fixing member 6 can be a combination of a bolt and a nut. By respectively forming through holes on the side walls of the guardrail body 2 and the connecting columns 32, when the connecting columns 32 are inserted into the first connecting groove 24, the bolt is sequentially passed through the guardrail body 2 and the connecting columns 32, and locked by the nut, so as to achieve fixation; in other embodiments, it can also be fixed by means of a slider.

[0041] Refer to Figure 6 and Figure 7, a rotating ring 42 is rotatably arranged on one side of the mounting base 4 facing the inner side of the hospital bed. A second connecting groove 43 for inserting the connecting column 32 is formed on the rotating ring 42, and a second fixing member 7 for fixing the connecting column 32 in the second connecting groove 43 is provided. Specifically, the second fixing member 7 includes a fixing arc rod 71, a first spring 72 and a control grip 73. An arc-shaped groove for the fixing arc rod 71 to slide is formed in the rotating ring 42. One end of the arc-shaped groove communicates with the second connecting groove 43. The first spring 72 is arranged in the arc-shaped groove and is located at one end of the fixing arc rod 71 away from the second connecting groove 43. An arc-shaped connecting hole is formed on the connecting column 32, and a positioning groove is formed on one side of the second connecting groove 43 away from the arc-shaped groove. When the connecting column 32 is inserted into the second connecting groove 43, the fixing arc rod 71 can pass through the connecting hole and be inserted into the positioning groove. At this time, the first spring 72 is in a compressed state, so that the connecting column 32 can be fixed to the rotating ring 42. The control grip 73 is arranged on the side wall of the fixing arc rod 71, and one end facing the inside of the hospital bed extends out of the rotating ring 42. An arc-shaped relief groove for the control grip 73 to slide is formed on the rotating ring 42. Two fixing arc rods 71 corresponding to the two connecting columns 32 are respectively arranged on the rotating ring 42. The two fixing arc rods 71 are preferably arranged on the same side, so that it is convenient to simultaneously control the two control grips 73 with one hand to simultaneously control the two fixing arc rods 71. In the two groups of second fixing members 7, two first springs 72 can be provided, or one first spring 72 can be shared.

[0042] During use, by pressing the control grip 73, the first spring 72 is compressed, and the fixing arc rod 71 is withdrawn from the positioning groove and the connecting hole, so that the installation and separation of the armrest seat 3 and the rotating ring 42 can be realized, and the operation is convenient and fast. Fixing the connecting column 32 on the rotating ring 42 can fix the armrest seat 3 on the mounting base 4. At the same time, since the rotating ring 42 rotates in the mounting base 4, during the movement of the mounting base 4 along with the driving device 5, especially when the mounting base 4 moves between the first section groove 211, the second section groove 212 and the third section groove 213 to change the exercise mode, the armrest seat 3 can rotate with the direction perpendicular to the surface of the guardrail body 2 as the rotation center, so that when the patient holds the mounting base 4, a relatively comfortable holding state can be always maintained.

[0043] Refer to Figure 6 and Figure 7, in an optional embodiment, a ring groove 44 for circumferential rotation of the rotating ring 42 is formed in the mounting base 4. A plurality of first positioning grooves 45 are circumferentially formed on the bottom wall of the ring groove 44. A first positioning hole 421 is provided on the rotating ring 42. A positioning bolt 46 is detachably provided on the mounting base 4. The positioning bolt 46 can pass through the first positioning hole 421 and be threadedly connected to the first positioning groove 45. In this way, the rotating ring 42 can be fixed by the positioning bolt 46 to restrict its rotation, so as to fix the armrest seat 3 at a certain angle. When the patient is at a certain position in the movement chute 21, such as reciprocally sliding in the first section of the chute 211 alone for elbow joint exercise, the armrest seat 3 can be fixed to restrict its rotation direction, which can improve the stability of the exercise.

[0044] The implementation principle of a modular electric hospital bed with rehabilitation effect in the embodiment of the present application is as follows: During daily use, the armrest seat 3 is fixed to the side of the guardrail body 2 facing the head of the bed through the first fixing member 6, which is convenient for patients with inconvenient bodies to borrow strength to get up or adjust their postures; when the patient needs to perform passive exercise, the first fixing member 6 can be unlocked, the armrest seat 3 can be removed, and through the second fixing member 7, the armrest seat 3 can be fixed on the mounting base 4. Then, according to the exercise mode required by the patient, first move the mounting base 4 into the first section of the chute 211, the second section of the chute 212 or the third section of the chute 213. Then, hold and fix the patient's hand to the armrest seat 3, and start the power source 54. Control the reciprocating movement of the mounting base 4 through the power source 54, so that the armrest seat 3 drives the hand to move and perform rehabilitation exercise on the corresponding part; after the exercise is over, fix the armrest seat 3 back to the side wall of the guardrail body 2.

[0045] Embodiment 2

[0046] The difference between the embodiment of the present application and Embodiment 1 is that a pull ring 33 is further provided on the armrest seat 3, and the patient can perform active exercise through the pull ring 33.

[0047] Referring to Figure 1 and Figure 8 , specifically, in the embodiment of the present application, a pull ring 33, a stretching rope 34 and a winding member 35 are further provided in the armrest seat 3. A limiting member 8 for restricting the sliding of the mounting base 4 is provided at the upper end of the second section of the chute 212 of the guardrail body 2. The pull ring 33 is detachably embedded in the armrest seat 3. Preferably, a groove body for embedding the pull ring 33 is formed on the side wall of the armrest seat 3 facing away from the hospital bed. The armrest seat 3 can be fixed in the groove body by interference fit or by setting positioning buckles. Optionally, a groove (not shown in the figure) convenient for taking out the pull ring 33 can be further provided on the surface of the armrest seat 3. One end of the stretching rope 34 is connected to the pull ring 33, and the other end is stored in the armrest seat 3 through the winding member 35. The stretching rope 34 has elasticity, and it is preferably made of rubber material. The patient can perform stretching strength rehabilitation training by stretching the pull ring 33.

[0048] Specifically, the winding member 35 includes a winding shaft 351, a winding roller 352, a coil spring 353, and a positioning plug 354. The winding shaft 351 is rotatably arranged in the armrest seat 3. The winding roller 352 is coaxially fixed to the winding shaft 351 and can be an I-shaped roller. One end of the stretching rope 34 away from the pull ring 33 is fixed to the side wall of the winding roller 352, and its rope body can be wound around the side wall of the winding roller 352.
