Description

Technical Field

[0001] The present invention belongs to the technical field of intensive care assisted turning, and particularly relates to a patient assisted turning device for intensive care. Background Art

[0002] Some patients in the intensive care unit lose their own control ability and need to stay in bed for a long time. And it is necessary for medical staff to turn them regularly to prevent pressure sores and ensure blood circulation. When turning the patients in the intensive care unit, because the bodies of the patients in the intensive care unit are out of control, medical staff need to place corresponding sponge support pads at the back, waist, legs and other positions of the patients. However, when placing the corresponding sponge support pads, medical staff need to hold the patient with one hand and place the sponge support pad with the other hand. Therefore, when placing the sponge pads at different positions, it is impossible to ensure the stability of the entire body of the patient, and it is easy to distort and deform the body of the patient, so it is very dangerous.

The first pulley 8018 is fixedly installed in the middle of the first threaded rod 8011, and the second pulley 8014 is fixedly installed in the middle of the second threaded rod 8013. The second pulley 8014 is connected to the first pulley 8018 through the synchronous belt 8015. The rotation of the first threaded rod 8011 can drive the second threaded rod 8013 to rotate through the action of the first pulley 8018, the second pulley 8014 and the synchronous belt 8015, ensuring that the second threaded rod 8013 can rotate synchronously with the first threaded rod 8011. The synchronous rotation of the first threaded rod 8011 and the second threaded rod 8013 can drive the sliders 8017 on the first threaded rod 8011 and the second threaded rod 8013 to move simultaneously, preventing the bed board 802 from tilting when the lifting bed board 802 is lifted, and ensuring the safety of the patient on the bed board 802.

The first pulley 8018, the second pulley 8014 and the synchronous belt 8015 are arranged in the groove 808. The arrangement of the groove 808 facilitates the installation of the first pulley 8018, the second pulley 8014 and the synchronous belt 8015, and can also play the role of protecting the first pulley 8018, the second pulley 8014 and the synchronous belt 8015.

[0077] In this embodiment, guide rails 506 are fixedly installed on the side walls of the fixed grooves 507 on the first rotating disc 502 and the second rotating disc 503. Guide grooves 8010 are formed at the bottoms of the supporting plates 801 on the first supporting assembly 8 and the second supporting assembly 6. The guide grooves 8010 are slidably matched with the guide rails 506. The arrangement of the guide rails 506 and the guide grooves 8010 can play a role in guiding and positioning during the installation of the supporting plate 801, improving the installation efficiency of the first supporting assembly 8 and the second supporting assembly 6.

[0078] As an optimized solution of this embodiment, as Figure 5As shown, the positioning member 3 includes a support rod 301, a baffle 302, a bend 304, and a hand-operated bolt 303. The support rod 301 is fixedly installed at the edge of the fixing groove 507 on the first rotating disk 502. The baffle 302 is fixedly installed at the end of the support rod 301. The setting of the baffle 302 can limit the supporting plate 801 to ensure the normal installation of the supporting plate 801. A bend 304 is provided at the top of the baffle 302.

The middle of the lifting rod 708 is installed on the lead screw 705 and is threadedly connected to the lead screw 705. A handle 706 is fixedly installed at the top of the lead screw 705. Positioning columns 707 are fixedly installed at both ends of the lifting rod 708. Positioning grooves 809 are provided at the other end of the supporting plates 801 on the first supporting assembly 8 and the second supporting assembly 6. The positioning columns 707 cooperate with the positioning grooves 809. The setting of the fixing member 7 can fix the supporting plate 801 to ensure that the bed board 802 and the supporting plate 801 are always in a stable state during operation. Rotating the handle 706 drives the lead screw 705 to rotate. The rotation of the lead screw 705 drives the lifting rod 708 to move downward. The downward movement of the lifting rod 708 drives the positioning column 707 to move downward until the positioning column 707 extends into the positioning groove 809, thereby fixing the supporting plate 801.

[0081] In this embodiment, the lifting rod 701 is rotatably connected to the rotating arm 702. The rotating arm 702 rotates around the connection between the lifting rod 701 and the rotating arm 702, which can drive the lifting rod 708, the lead screw 705, and the vertical rod 703 to rotate, preventing interference with the rotating arm 702 when installing the first supporting assembly 8 and the second supporting assembly 6.

[0082] In this embodiment, vertical rods 703 are fixedly installed on both sides of the rotating arm 702. A guide block 704 is fixedly installed on the side wall of the vertical rod 703.

[0083] As an optimized solution of this embodiment, as Figure 8 、 Figure 9 shown, it further includes a locking member 2. The locking member 2 is installed on the cross bar 4. The locking member 2 includes a push-pull rod 202, limiting rods 201 installed at both ends of the push-pull rod 202, a spring 205, a guide rod 204, and a lifting plate 2010. The guide rod 204 is fixedly installed at the bottom of the cross bar 4. A fixed block 206 is provided at the bottom of the guide rod 204. The limiting rod 201 is slidably matched with the cross bar 4. Limiting grooves 505 matched with the limiting rod 201 are formed on both the first rotating disk 502 and the second rotating disk 503. The lifting plate 2010 is slidably installed on the guide rod 204 of the support plate. Limiting columns 2011 are provided at both ends of the lifting plate 2010. Through holes 2012 are provided at both ends of the limiting rod 201. The limiting columns 2011 penetrate through the cross bar 4 and extend into the through holes 2012. The locking member 2 is used to lock the first rotating disk 502 and the second rotating disk 503, ensuring that the first rotating disk 502 and the second rotating disk 503 are always in a stable state during the working process, and ensuring the safety of critically ill patients.

[0084] In this embodiment, the spring 205 is sleeved on the guide rod 204, and the spring 205 is located between the fixed block 206 and the lifting plate 2010. The spring 205 is used to provide power for the lifting plate 2010, ensuring that the lifting plate 2010 always moves upward, so that the limiting column 2011 on the lifting plate 2010 always cooperates with the through hole 2012 on the limiting rod 201, and also ensuring that the limiting rod 201 always cooperates with the limiting groove 505 on the first rotating disk 502 or the second rotating disk 503.

[0085] As an optimized solution of this embodiment, as Figure 8 、 Figure 9As shown in the figure, a sliding rod 207 is provided at the bottom of the lifting plate 2010. The sliding rods 207 are symmetrically arranged on both sides of the guiding rod 204. Chutes 209 are formed on both sides of the fixed block 206. The chutes 209 are in sliding fit with the sliding rods 207. A pedal 208 for easy stepping is fixedly installed at the bottom of the sliding rod 207. The setting of the fixing hole 203 facilitates the staff to pull the push rod 202, improving work efficiency.

[0086] In this embodiment, a fixing hole 203 for easy gripping is formed in the middle of the push rod 202, facilitating the staff to pull the push rod 202 and improving work efficiency.

[0087] In this embodiment, the guiding rod 204 adopts a structure with an elliptical cross-section, ensuring that the lifting plate 2010 does not shake during the lifting movement along the lifting plate 2010, greatly ensuring the normal operation of the device.

[0088] In this embodiment, a strip-shaped groove 2013 is also formed at the bottom of the sliding rod 207. The end of the strip-shaped groove 2013 coincides with the through holes 2012 at both ends of the limiting rod 201, and the strip-shaped groove 2013 is in sliding fit with the positioning post 707. The setting of the strip-shaped groove 2013 can limit the limiting rod 201, preventing the large amplitude of pulling the limiting rod 201 from pulling the limiting rod 201 out of the cross bar 4 and ensuring the normal operation of the limiting rod 201.

[0089] Embodiment 1

[0090] During operation, the first supporting component 8 or the second supporting component 6 is installed on the vertical surface of the fixing groove 507. The guide groove 8010 on the supporting plate 801 is thus pushed onto the guide rail 506 on the first rotating disc 502 until the end of the supporting plate 801 contacts the baffle 302. Rotate the hand screw 303 until the end of the hand screw 303 extends into the fixing hole 203 at the end of the supporting plate 801, achieving the purpose of fixing one end of the supporting plate 801. Finally, rotate the rotating arm 702 until the vertical rod 703 and the guiding block 704 on the rotating arm 702 are located above the supporting plate 801. Rotate the handle 706 to drive the lead screw 705 to rotate until the positioning post 707 on the lifting rod 708 penetrates through the guiding block 704 and extends into the positioning groove 809, thereby achieving the purpose of fixing the other end of the supporting plate 801 and ensuring that the supporting plate 801 and the bed board 802 are always in a stable state during operation;

[0091] Step on the pedal 208 downward to drive the lifting plate 2010 to move downward along the guide rod 204 until the limit post 2011 is pulled out from the through hole 2012 at one end of the limit rod 201, and the top of the limit post 2011 is located in the strip groove 2013. Pull the push rod 202 to drive the limit rod 201 out of the limit groove 505 on the first rotating disk 502 or the second rotating disk 503 until the through hole 2012 on the other end of the limit post 2011 coincides with the through hole 2012 on the other end of the limit rod 201. Stop stepping on the pedal 208. Under the action of the spring 205, the lifting plate 2010 resets, driving the limit post 2011 to move upward until the limit post 2011 extends into the through hole 2012 on the other end of the limit rod 201;

[0092] Rotate the handle 8012 on the vertically arranged first supporting component 8 or the second supporting component 6 to drive the first threaded rod 8011 to rotate. The rotation of the first threaded rod 8011 drives the first belt pulley 8018 to rotate. The first belt pulley 8018 drives the second belt pulley 8014 to rotate through the synchronous belt 8015. The rotation of the second belt pulley 8014 drives the second threaded rod 8013 to rotate. The rotation of the first threaded rod 8011 and the second threaded rod 8013 will drive the sliders 8017 installed on both sides of the center lines of the first threaded rod 8011 and the second threaded rod 8013 to move simultaneously. While the sliders 8017 are moving, one end of the connecting rod 8016 will be driven to move, and the other end of the connecting rod 8016 will push the bed board 802 to move to the side away from the supporting board 801 until the bed board 802 contacts the patient on the bed board 802 of the second supporting component 6 or the first supporting component 8 on the horizontal plane;

[0093] Turn on the driving motor 508 to drive the worm 509 to rotate. The worm 509 meshes with the worm gear 5010. The rotation of the worm 509 drives the worm gear 5010 to rotate. The rotation of the worm gear 5010 drives the rotating shaft 5011 to rotate. The rotation of the rotating shaft 5011 drives the second gear 5012 to rotate. The second gear 5012 meshes with the first gear 5013. The rotation of the second gear 5012 drives the first gear 5013 to rotate. The rotation of the first gear 5013 drives the first rotating disk 502 and the second rotating disk 503 to rotate. The first rotating disk 502 and the second rotating disk 503 will drive the patient on the first supporting component 8 or the second supporting component 6 to rotate 90°. Finally, with the assistance of medical staff, the purpose of turning the patient over by 180° is achieved, and the labor intensity of medical staff is greatly reduced during the entire turning process;

[0094] After the turning is completed, the staff can remove the vertical second supporting component 6 or the first supporting component 8 as needed, and at the same time, the locking member 2 resets to achieve the purpose of limiting the first rotating disk 502 and the second rotating disk 503;

[0095] If turning over is needed again, just repeat the above steps.

[0096] Example 2

[0097] When it is necessary to adjust the position where the patient's turning over is completed, before turning over the patient, it is necessary to rotate the first driving screw rod 8011 on the horizontally placed first supporting component 8 or the second supporting component 6. The rotation of the first driving screw rod 8011 drives the rotation of the first belt pulley 8018. The first belt pulley 8018 drives the rotation of the second belt pulley 8014 through the synchronous belt 8015. The rotation of the second belt pulley 8014 drives the rotation of the second driving screw rod 8013. The rotation of the first driving screw rod 8011 and the second driving screw rod 8013 drives the sliders 8017 installed on both sides of the center lines of the first driving screw rod 8011 and the second driving screw rod 8013 to move simultaneously. While the sliders 8017 are moving, one end of the connecting rod 8016 is driven to move, and the other end of the connecting rod 8016 will push the bed board 802 to move away from the supporting board 801 until the bed board 802 is lifted to a suitable position to ensure that the position where the patient is located after turning over is a suitable position, and then the turning member is opened to drive the patient to turn over.

[0098] Example 3

[0099] When a critically ill patient only needs to turn over by 90°, it is only necessary to adjust the bed board on the vertically arranged first supporting component 8 or the second supporting component 6 to contact one side of the critically ill patient on the horizontally arranged second supporting component 6 or the first supporting component 8, and then open the turning member to turn over by 90°. At this time, the horizontally arranged second supporting component 6 or the first supporting component 8 becomes vertical to achieve the purpose of supporting the side of the critically ill patient, and the vertically arranged first supporting component 8 or the second supporting component 6 becomes horizontal to achieve the purpose of supporting the critically ill patient from the bottom, ensuring that the body of the critically ill patient is still in a stable state after turning over and guaranteeing the personal safety of the critically ill patient.
