Technical Field

[0001] This utility model belongs to the field of medical facility technology, and in particular relates to an auxiliary turning device for bedridden patients. Background Technology

[0002] Bedridden patients refer to individuals who require long-term or short-term bed rest due to illness, trauma, post-operative rehabilitation, or declining physical function. These patients are prone to various complications due to limited mobility and require professional care and attention. Hospital beds are basic medical facilities located in hospitals, nursing centers, and other similar settings. For bedridden patients, beds with assisted turning functions help reduce the workload of medical staff. Regular turning care can promote limb movement and alleviate pressure sores.

[0003] Existing technologies include hospital beds with electrically assisted turning functions. These beds have deformable surfaces, driven by electric actuators or other motorized components, to assist patients in turning over. However, the purchase cost of such beds is high. Meanwhile, a large number of ordinary hospital beds remain in use. How to modify ordinary hospital beds to include basic assisted turning functions is a crucial issue that needs attention. Modifying ordinary hospital beds to suit bedridden patients will help reduce the burden on healthcare. Therefore, there is a need to develop and design an assisted turning device for bedridden patients. Summary of the Invention

[0004] The purpose of this invention is to provide a bedridden patient assistive turning device that can be applied to ordinary hospital beds to enable them to have good assistive turning functions, so as to meet the needs of bedridden patients and reduce the operational burden of medical staff.

[0005] The technical solution adopted by this utility model is as follows: a bedridden patient assistive turning device, including a middle beam fixedly connected to the bed frame, a left frame and a right frame respectively hinged on both sides of the middle beam, a left support frame installed inside the left frame, a right support frame installed inside the right frame, a left roller and a left outer support beam installed on the outside of the left frame, and a right roller and a right outer support beam installed on the outside of the right frame, and also includes two hand-cranked components for driving the left and right rollers respectively; it also includes a mattress, the mattress including a left mattress on the left frame and a right mattress on the right frame; and a mattress pad, the middle of which is located above the mattress, with the left side wound on the left roller and the right side wound on the right roller.

[0006] Preferably, the inner top of the left and right mattresses are connected as one piece, the left mattress is fixedly connected to the left support frame, and the right mattress is fixedly connected to the right support frame.

[0007] Preferably, the hand crank assembly includes a worm gear mounted on the left or right frame via a bearing seat and a worm wheel mounted on the shaft end of the left or right reel. The worm wheel and the worm gear form a worm gear structure. A base is mounted on the outer end of the worm gear, and a connecting seat with a groove is mounted on the outer side of the base. It also includes a Z-shaped crank handle, the inner end of which is located in the groove of the connecting seat and is hinged.

[0008] Preferably, the mattress layer is a canvas layer, and a plastic underlayer is provided on the bottom surface of the canvas layer to reduce frictional resistance.

[0009] Preferably, longitudinal through mounting holes are provided at both ends of the intermediate beam, and the two ends of the intermediate beam are fixedly connected to the bed frame by assembly bolts.

[0010] Preferably, handles are installed at the front and rear of the left outer support beam, and handles are installed at the front and rear of the right outer support beam.

[0011] The advantages and positive effects of this utility model are:

[0012] This invention provides an auxiliary turning device for bedridden patients, applicable to existing ordinary hospital beds. By modifying ordinary hospital beds, it enables patients to turn over. The device is installed on the bed frame via a central beam. Its left frame and left mattress, as well as its right frame and right mattress, can be raised and lowered respectively around their respective hinges. When raised, the patient's body is lifted and gradually posed in a ready-to-turn position. Medical staff on the other side can then stabilize the patient and slowly complete the turning motion. Throughout the process, medical staff do not need to directly lift the patient, thus reducing their workload, meeting the needs of bedridden patients, and minimizing discomfort.

[0013] On the other hand, this assisted turning device is equipped with a patient transfer component consisting of a left roller, a right roller, and a bed pad. Before turning the patient, the position of the bedridden patient on the bed can be adjusted as needed, moving the patient to the left or right side of the mattress to prepare for turning. The patient transfer component allows medical staff to move the patient without directly lifting the patient's body, further reducing the workload of medical staff and the discomfort caused to the bedridden patient during the turning process.

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0020] Please see Figure 1 and Figure 2 The bedridden patient turning device of this utility model includes a middle beam 3 fixedly connected to the bed frame 16 of a regular hospital bed. A left frame 2 and a right frame 4 are respectively hinged on both sides of the middle beam 3 using hinges 7. A left support frame 5 is installed inside the left frame 2, and a right support frame 6 is installed inside the right frame 4.

[0021] In this embodiment, longitudinally penetrating mounting holes are provided at both ends of the intermediate beam 3, and the two ends of the intermediate beam 3 are fixedly connected to the bed frame 16 using assembly bolts 15. During installation, the intermediate beam 3 should be positioned in the middle of the bed frame 16 of a standard hospital bed. Mounting holes are drilled on the profile of the bed frame 16 at positions corresponding to the mounting holes at the ends of the intermediate beam 3. Assembly bolts 15 are installed in both the front and rear sets of mounting holes to fix the intermediate beam 3 to the bed frame 16. Therefore, this auxiliary turning device... Figure 1 In the state shown, both the left frame 2 and the right frame 4 rest on the bed frame 16, which bears the weight.

[0022] The left frame 2 and the right frame 4 are each welded together from the front frame, rear frame, inner frame, and outer frame. The left support frame 5 is welded and installed inside the left frame 2 to enhance the overall structural strength, and the right support frame 6 is welded and installed inside the right frame 4 to enhance the overall structural strength. The left hinge 7 is installed between the inner frame of the left frame 2 and the middle beam 3, and the right hinge 7 is installed between the inner frame of the right frame 4 and the middle beam 3. Therefore, the left frame 2 and the right frame 4 can swing up or down with their respective hinge 7 as the center, with the downward swing ending at a horizontal position on the bed frame 16.

[0023] A left-side roller 9 and a left-side outer support beam 10 are installed on the outside of the left-side frame 2, and a right-side roller 12 and a right-side outer support beam 11 are installed on the outside of the right-side frame 4. The frame also includes two hand-cranked components 1, one on the left and one on the right, which drive the left-side roller 9 and the other on the right-side roller 12 to rotate respectively.

[0024] like Figure 1 As shown, the front and rear frames of the left frame 2 extend outwards by a certain length, and the left outer support beam 10 is fixed between the ends of the front and rear frames. The left scroll 9 is located between the left outer support beam 10 and the outer frame of the left frame 2, while the front and rear axle seats of the left scroll 9 are respectively installed on the front and rear frames of the left frame 2. Similarly... Figure 1 As shown, the front and rear frames of the right frame 4 extend outward by a certain length, and the right outer support beam 11 is installed and fixed between the ends of the front and rear frames. The right scroll 12 is located between the right outer support beam 11 and the outer frame of the right frame 4, and the front and rear shaft seats of the right scroll 12 are respectively installed on the front and rear frames of the right frame 4.

[0025] Please see Figure 3 It can be seen that:

[0026] The hand crank assembly 1 includes a worm 1-1 mounted on the left frame 2 or the right frame 4 via a bearing 1-3, and a worm wheel 1-2 mounted on the shaft end of the left reel 9 or the right reel 12. The worm wheel 1-2 and the worm 1-1 form a worm wheel and worm gear structure. A base 1-5 is mounted on the outer end of the worm 1-1, and a connecting seat 1-4 with a groove is mounted on the outer side of the base 1-5. It also includes a Z-shaped crank handle 1-6, the inner end of which is located in the groove of the connecting seat 1-4 and is hinged.

[0027] As shown in the figure, in order to avoid adverse effects on patients getting in and out of bed and on nursing operations by medical staff, the hand-cranked component 1 is placed at the foot of the bed. Figure 1 (As shown in the diagram, the upper part is the foot of the bed and the lower part is the head of the bed). The worm gear mechanism is located inside the rear frame of the left frame 2 and the right frame 4, achieving a concealed installation. When operating the hand crank assembly 1, the worm gear mechanism drives the left reel 9 or the right reel 12 to rotate.

[0028] Because the inner end of the crank handle 1-6 is located in the groove of the connecting seat 1-4 and is hinged, when performing hand cranking, the crank handle 1-6 is raised to... Figure 3 As shown in the hand-crank operation state, after the hand-crank operation is completed, the crank handle 1-6 can be folded downwards and stored with the hinge axis between it and the connecting seat 1-4 as the center. In this way, the hand-crank assembly 1 will not protrude outwards from the device, thus avoiding obstruction to patients and medical staff.

[0029] The system also includes a mattress 13, which comprises a left mattress on the left frame 2 and a right mattress on the right frame 4. In this embodiment, the inner top edges of the left and right mattresses of the mattress 13 are connected as one unit. The left mattress is fixedly connected to the left support frame 5, and the right mattress is fixedly connected to the right support frame 6. This prevents separation between the left and right mattresses, between the left mattress and the left support frame 5, and between the right mattress and the right support frame 6, thus preventing displacement of the left and right mattresses during the turning process. Specifically, the inner top edges of the left and right mattresses can be connected by stitching, ensuring that the connection between the left and right mattresses does not affect their upward and downward swinging movements. The left mattress can be fixed to the left support frame 5, and the right mattress can be fixed to the right support frame 6 using straps located at the bottom.

[0030] It also includes a mattress pad 14, with the middle of the mattress pad 14 located above the mattress 13, the left side wound around the left roller 9, and the right side wound around the right roller 12. When the left hand crank component 1 is operated, the left side of the mattress pad 14 gradually rolls up to the left roller 9 while the right side of the mattress pad 14 gradually releases from the right roller 12. Similarly, when the right hand crank component 1 is operated, the right side of the mattress pad 14 gradually rolls up to the right roller 12 while the left side of the mattress pad 14 gradually releases from the left roller 9. During this process, the middle of the mattress pad 14 moves to the left or right above the mattress 13. This allows a bedridden patient lying flat on the mattress pad 14 to move their body to the left and onto the left side of the mattress, or to the right and onto the right side of the mattress, which prepares them for subsequent turning over.

[0031] In this embodiment, the mattress pad 14 is a canvas layer, with a plastic underlayer on its bottom surface to reduce frictional resistance. The canvas layer has a certain degree of roughness, and the plastic underlayer reduces the coefficient of friction, thus the mattress pad 14 can be described as having a relatively smooth bottom surface. Therefore, when the hand-cranked assembly 1 drives the mattress pad 14 to move left or right on the mattress 13, the relatively smooth bottom surface reduces resistance to movement, making the movement smoother. Figure 2 As shown, the two sides of the mattress pad 14 pass around the two side edges of the mattress 13 and pass under it. Since the two side edges of the mattress 13 are not directly pressed, and with the drag-reducing effect of the relatively smooth bottom surface, the mattress pad 14 does not obstruct the two side edges of the mattress 13.

[0032] In this embodiment, handles 8 are installed at the front and rear of the left outer support beam 10, and at the front and rear of the right outer support beam 11. The purpose of the handles 8 is to improve the convenience for medical staff to swing the left frame 2 or the right frame 4 up or down. It can be imagined that the position of the handles 8 can be set as needed.

[0033] How to use:

[0034] The assistive turning device is installed onto the bed frame 16 of a regular hospital bed. The front and rear ends of the intermediate beam 3 are fixedly connected to the bed frame 16 using two assembly bolts 15. At this point, as... Figure 1 As shown, the left frame 2 and the right frame 4 rest on the bed frame 16, and the cranks 1-6 of the two hand-cranked components 1 are folded downwards; a sheet can be laid on the bed pad 14 or the bedridden patient can lie directly on the bed pad 14.

[0035] When turning a patient over, first observe the patient's position on the bed. If the patient's body is pressing on the center line (the seam between the left and right mattresses), the hand crank component 1 should be operated to adjust the patient's position. For example, if the patient's body is more on the left mattress, operate the left hand crank component 1 to roll the left side of the mattress pad 14 more onto the left roller 9 while the right roller 12 rolls freely until the patient's body is off the center line and completely on the left mattress. Then, the medical staff on the left side slowly raise the left frame 2. When the left frame 2 and the left mattress are raised to a certain height, the patient's body rolls to the right and falls onto the right mattress. Of course, during this process, the medical staff on the right side can also raise the right frame 4 and the right mattress to a certain height in advance to receive the patient's body. After receiving the body, the patient is then smoothly lowered to a horizontal position, and the patient's overturning is complete. It is worth noting that the patient's body must be stabilized throughout the overturning operation to ensure the safety of the action.
