Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a medical body position adjustment device for critically ill patients. Background Art

[0002] During the treatment of critically ill patients, since most of them are unable to move by themselves, and in order to avoid poor blood circulation caused by patients lying in bed for a long time, which may lead to the occurrence of pressure sores, medical staff usually use critically ill patient position adjustment devices to turn patients over.

[0003] When the existing medical body position adjustment devices for critically ill patients are in use, most of them have poor protection functions, which makes it difficult for medical staff to turn over patients who are unconscious, restless or large in size. Since these patients cannot cooperate well with the turning action, their bodies may move uncontrollably to the bedside, making it easy for the patients to fall off the bed, thereby causing more serious injuries to the patients themselves.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing medical body position adjustment devices for critically ill patients on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

The upper surface of each concave block 2105 is in contact with the bottom surface of the adjustment plate 2102, and the power provided by the hydraulic rod 2104 cooperates with the connecting block 2103 and the concave block 2105 to drive the adjustment plate 2102 is rotated, so that the adjustment plate 2102 pushes the patient to turn over, and a toggle block 2106 is fixedly installed on the outer surface of the rotating shaft 2101, and two connecting plates 2107 are fixedly installed on the left side of the frame 11, and two connecting springs 2108 are fixedly installed on the side where the two connecting plates 2107 are close to each other, and a moving plate 2109 is fixedly installed on the end of each group of connecting springs 2108 away from the connecting plate 2107, and the number of each group of connecting springs 2108 is two, and a connecting ball 2110 is fixedly installed on the side where the two moving plates 2109 are close to each other. The setting of the connecting ball 2110 makes it convenient for the toggle block 2106 to press it, and will not prevent the toggle block 2106 from rotating. The two connecting plates A first touch switch 2111 is fixedly installed on the side where the two tactile switches 2107 are close to each other. The first touch switch 2111 is only triggered once during a turning over action. A mounting frame 2112 is fixedly installed on the front and back of the frame 11. The interiors of the two mounting frames 2112 are rotatably connected with reciprocating screw rods 2113. The bottom ends of the two reciprocating screw rods 2113 penetrate the mounting frames 2112 and are fixedly installed with connecting gears 2114. The outer surfaces of the two reciprocating screw rods 2113 are threadedly connected with protective plates 2115. A rubber block is provided on the side of the protective plate 2115 facing the frame 11, so as to increase the comfort of the patient's contact with the protective plate 2115. A mounting plate 2116 is fixedly installed on the front and back of the frame 11. The two mounting plates An electric push rod 2117 is fixedly installed on the upper surface of 2116, and a moving frame 2118 is fixedly installed on the telescopic end of the two electric push rods 2117. A rotating motor 2119 is fixedly installed on the inner top wall of the two moving frames 2118. A rotating gear 2120 is fixedly installed on the output end of the two rotating motors 2119. The interior of the two moving frames 2118 is rotatably connected with a rotating shaft 2121. The top of the two rotating shafts 2121 is fixedly installed with a rotating gear 2122. The outer surfaces of the two rotating gears 2122 are meshed with the outer surface of the connecting gear 2114. A rotating disk 2123 is fixedly installed on the bottom end of the two rotating shafts 2121. A connecting box 2124 is fixedly installed on the bottom surface of the two moving frames 2118.The inner walls of the two connection boxes 2124 are fixedly installed with electric telescopic rods 2125, and the telescopic ends of the two electric telescopic rods 2125 are fixedly installed with limit posts 2126. The two limit posts 2126 are clamped inside the rotating disk 2123. The power provided by the electric telescopic rods 2125 makes the limit posts 2126 clamped inside the rotating disk 2123, thereby locking the rotating disk 2123. The left sides of the two mounting frames 2112 are fixedly installed with laser rangefinders 2 127, the left side surfaces of the two protective plates 2115 are fixedly mounted with baffles 2128, and the height of the baffles 2128 is measured by using the laser rangefinder 2127, so that when the protective plates 2115 are in the raised state, the first touch switch 2111 is not triggered, and the first touch switch 2111 is electrically connected to the rotating motor 2119 and the electric push rod 2117 through wires, so that when the first touch switch 2111 is triggered, the electric push rod 2117 and the rotating motor The machine 2119 runs successively, so that the electric push rod 2117 drives the moving frame 2118 to move downward, thereby meshing the rotating gear 2120 with the connecting gear 2114, and then the power provided by the rotating motor 2119 is used to drive the reciprocating screw rod 2113 to rotate, so that the protective plate 2115 moves up and down for a cycle, and the time for completing the cycle is controlled after the patient turns over. Then, the power provided by the electric push rod 2117 is used to return the moving frame 2118 to its original position, that is, the rotating gear 2122 is meshed with the connecting gear 2114, so that it is convenient for subsequent medical staff to manually adjust the protective plate 2115. By providing a protective unit 21, the device automatically raises the protective plate 2115 facing the patient during the process of turning the patient over, thereby shielding the side of the patient turning around, thereby avoiding the risk of the patient falling out of bed during the process of turning around, so that the device plays a better protective role for the patient.

Each slider 2129 is slidably connected inside the slide groove 2130. The number of the slide grooves 2130 is consistent with the number of sliders 2129. The installation of the slider 2129 and the slide groove 2130 plays a role in limiting the moving trajectory of the concave block 2105, thereby avoiding the concave block 2105 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the concave block 2105.

[0045] See also Figure 5Two telescopic columns 2131 are fixedly installed on the side where the two connecting plates 2107 are close to each other. The telescopic ends of the two groups of telescopic columns 2131 are respectively fixedly connected to the side where the two moving plates 2109 are away from each other. The installation of the telescopic columns 2131 plays a role in limiting the moving trajectory of the moving plates 2109, thereby ensuring the stability of the movement of the moving plates 2109.

[0046] See also Figure 4 and Figure 6 Slide bars 2132 are fixedly installed on the inner walls of the two mounting frames 2112, and the outer surfaces of the two slide bars 2132 are slidably connected to the inner walls of the two protective plates 2115 respectively. The installation of the slide bars 2132 serves to limit the moving trajectory of the protective plates 2115, thereby ensuring the stability of the movement of the protective plates 2115.

[0047] See also Figure 7-Figure 8 A slide plate 2133 is fixedly installed on the side where the two mobile racks 2118 are close to each other, and slide rails 2134 are provided on the front and back of the rack 11. The two slide plates 2133 are respectively slidably connected to the inside of the two slide rails 2134. The installation of the slide plates 2133 and the slide rails 2134 plays a role in limiting the moving trajectory of the mobile rack 2118, thereby ensuring the stability of the movement of the mobile rack 2118.

[0048] The specific implementation of this embodiment is as follows: when in use, the medical staff places the patient on the bed 12. When the patient needs to be turned over, the medical staff opens the hydraulic rod 2104 through the external remote control device, and uses the power provided by the hydraulic rod 2104 to drive the concave block 2105 to move, so that the concave block 2105 cooperates with the slider 2129 and the slide groove 2130 to drive the adjustment plate 2102 to rotate, and then the adjustment plate 2102 pushes the patient to turn over. During the rotation of the adjustment plate 2102, the rotating shaft 2101 drives the toggle block 2106 to rotate, so that the toggle block 2106 squeezes the connecting ball 2110 during the rotation, so that the connecting ball 2110 cooperates with the moving plate 2109 to press the connecting spring 21 08 is squeezed, so that the moving plate 2109 contacts the first touch switch 2111, and the laser rangefinder 2127 is used to measure the height of the baffle 2128 in the process again, so that when the protective plate 2115 is in the raised state, the first touch switch 2111 is not triggered. When the first touch switch 2111 is triggered, the first touch switch 2111 controls the electric push rod 2117 and the rotating motor 2119 facing the patient to run. If the adjustment plate 2102 located at the rear rotates, the electric push rod 2117 and the rotating motor 2119 located in the front are in operation. Similarly, the operation of the two electric push rods 2117 and the rotating motor 2119 at the front and rear are intersected with the operation positions of the two adjustment plates 2102. The power provided by the rod 2117 drives the moving frame 2118 to move downward, so that the rotating gear 2120 is meshed with the connecting gear 2114, and then the power provided by the rotating motor 2119 is used to drive the rotating gear 2120 to rotate, so that the rotating gear 2120 cooperates with the connecting gear 2114 to drive the reciprocating screw rod 2113 to rotate, and then the reciprocating screw rod 2113 drives the protective plate 2115 to move up and down, so that the protective plate 2115 shields the patient and avoids the risk of the patient falling out of bed. When the patient is turned over, the power provided by the electric push rod 2117 drives the moving frame 2118 to move upward, so that the rotating gear 2122 is meshed with the connecting gear 2114, so that it is convenient for medical staff to The height of the protective plate 2115 is adjusted as needed. When the medical staff adjusts the height of the protective plate 2115, the power provided by the electric telescopic rod 2125 is used to drive the limit column 2126 to move to the side away from the rotating disk 2123. Then the medical staff rotates the rotating disk 2123, so that the rotating disk 2123 drives the rotating shaft 2121 and the rotating gear 2122 to rotate, and then the rotating gear 2122 drives the connecting gear 2114 and the reciprocating screw rod 2113 to rotate, so that the medical staff adjusts the height of the protective plate 2115 as needed. After the adjustment is completed, the electric telescopic rod 2125 is used to provide power to clamp the limit column 2126 inside the rotating disk 2123, thereby locking the rotating disk 2123.

The ends of the two air outlet pipes 2216 close to each other are fixedly installed with a delivery pipe 2219, and the ends of the two delivery pipes 2219 away from the air outlet pipes 2216 successively penetrate the frame 11 and the rubber pad 2202 and penetrate into the interior of the airbag 2203. The sides of the two airbags 2203 away from each other are fixedly connected with exhaust pipes 2220, and the outer surfaces of the two exhaust pipes 2220 are fixedly connected with solenoid valves 2221. Two placement plates 2222 are fixedly installed on the inner wall of the frame 11, and the upper surfaces of the two placement plates 2222 are fixedly installed with second touch switches 2223.The bottom surfaces of the two adjustment plates 2102 are in contact with the upper surface of the second touch switch 2223. The front and rear second touch switches 2223 are cross-connected and electrically connected to the front and rear solenoid valves 2221, so that when the second touch switch 2223 is triggered, the solenoid valve 2221 opens to discharge the gas. By providing the buffer unit 22, the protection unit 21 of the device fills the airbag 2203 facing the side with gas during operation, so that the airbag 2203 expands to support the patient, and then discharges the gas inside the airbag 2203, so that the patient slowly descends with the airbag 2203, thereby avoiding the patient from falling out of bed due to the large inertia when the patient turns over, and further plays a role in safety protection for the patient.

[0051] See also Figure 9-10 Four limit blocks 2224 are fixedly installed on the left side of the frame 11, and the inner wall of each limit block 2224 is slidably connected to the outer surface of the rack plate 2212. The installation of the limit block 2224 limits the moving trajectory of the rack plate 2212, thereby preventing the rack plate 2212 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the rack plate 2212.

[0052] The specific implementation of this embodiment is as follows: during the rotation of the rotating shaft 2101, the rotating shaft 2101 drives the large gear 2204 to rotate, so that the large gear 2204 drives the small gear 2207 meshing with it to rotate, and then the small gear 2207 drives the rotating rod 2206 and the transmission gear 2208 to rotate, so that the transmission gear 2208 drives the two mounting gears 2210 meshing with it to rotate, and then the mounting gear 2210 drives the rotating rod 2209 and the incomplete gear 2211 to rotate, so that the two incomplete gears 2211 alternately drive the rack plate 2212 to move up and down reciprocatingly, and then the rack plate 2212 drives the pressing plate 2213 to move up and down reciprocatingly, so that the pressing plate 2213 presses the inflatable block 2215. Repeated pressing makes the inflatable block 2215 cooperate with the two one-way valves 2218 to allow external air to enter the interior of the inflatable block 2215 through the air inlet pipe 2217, and then enter the interior of the airbag 2203 through the air outlet pipe 2216 and the delivery pipe 2219, so that the airbag 2203 expands, thereby supporting the patient who turns over. When the rotating shaft 2101 drives the adjustment plate 2102 back to its original position, the adjustment plate 2102 triggers the second touch switch 2223, so that the second touch switch 2223 controls the corresponding solenoid valve 2221 to open, so that the gas inside the airbag 2203 is discharged through the exhaust pipe 2220, so that the patient slowly falls on the bed body 12 during the exhaust of the airbag 2203, thereby preventing the patient from falling out of bed due to the large inertia.

[0053] Example 3: Please refer to Figure 1 and Figure 13-Figure 16 The present invention provides a technical solution: a medical device for adjusting the body position of critically ill patients. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A restraint mechanism 3 is arranged above the frame 11, and the processing mechanism 2 is used in conjunction with the restraint mechanism 3. The restraint mechanism 3 is used to limit the position of the patient when turning over.

[0054] As a further limitation of the constraint mechanism 3 of the present invention, the constraint mechanism 3 includes four elastic bands 301, the bottom surface of each elastic band 301 is fixedly installed with the inner wall of the rubber pad 2202, the upper surface of each group of elastic bands 301 is fixedly installed with a magnet 302, the number of each group of elastic bands 301 is two, the upper surface of the frame 11 is fixedly installed with a connecting frame 303, the inner top wall of the connecting frame 303 is fixedly installed with two groups of cylinders 304, the number of each group of cylinders 304 is at least two, and each The telescopic ends of the cylinders 304 are fixedly mounted with electromagnets 305, the bottom surface of one of the electromagnets 305 is in contact with the upper surface of one of the magnets 302, and the magnet 302 is lifted into the air by the attraction between the electromagnet 305 and the magnet 302, thereby causing the elastic band 301 to unfold. The inner wall of the connecting frame 303 is fixedly mounted with four fixed boxes 306, one of the magnets 302 is clamped in the inside of the two fixed boxes 306, and the inner wall of each fixed box 306 is fixed with A fixed spring 307 is fixedly installed, and a third touch switch 309 is fixedly installed on the inner wall of each fixed box 306. A wedge block 308 is fixedly installed on the end of each group of fixed springs 307 away from the third touch switch 309. A linear driver 310 is fixedly installed on the upper surface of each fixed box 306. The third touch switch 309 is electrically connected to the linear driver 310. When the third touch switch 309 is triggered, the linear driver 310 located on the same fixed box 306 contracts, and then cooperates with the attraction of the wedge block 308, the L-shaped plate 311 and the electromagnet 305 to limit the magnet 302. The telescopic end of each linear driver 310 is fixedly installed with an L-shaped plate 311, and each L-shaped plate 311 is clamped in the interior of the fixed box 306. By providing a constraint mechanism 3, the device uses the elastic belt 301 to limit the side of the patient's flip during the flipping process, thereby further avoiding the risk of the patient falling out of bed.

[0055] See also Figure 15-16 Two T-shaped plates 312 are fixedly installed on the front and back of each wedge block 308, and two connecting grooves 313 are provided on the inner wall of each fixed box 306. Each T-shaped plate 312 is slidably connected inside the connecting groove 313. The installation of the T-shaped plates 312 and the connecting grooves 313 serves to limit the moving trajectory of the wedge block 308, thereby ensuring the stability of the movement of the wedge block 308.

[0056] The specific implementation of this embodiment is as follows: while the protection unit 21 is running, the medical staff opens the cylinder 304 and the electromagnet 305 on the patient side, and uses the power provided by the cylinder 304 to drive the electromagnet 305 to move downward, so that the magnet 302 is adsorbed on the electromagnet 305 by the attraction between the electromagnet 305 and the magnet 302, and then uses the power provided by the cylinder 304 to drive the magnet 302 to move upward, thereby making the elastic band 301 vertically unfolded. In the process of the magnet 302 moving upward, the magnet 302 will push the wedge block 308 to move to the side close to the fixed spring 307, so that The fixed spring 307 is compressed, and the wedge block 308 comes into contact with the third touch switch 309. When the magnet 302 moves above the wedge block 308, the operation of the cylinder 304 is stopped. At this time, under the action of the elastic force of the fixed spring 307, the wedge block 308 supports the magnet 302. At the same time, the linear drive 310 provides power to insert the L-shaped plate 311 into the interior of the fixed box 306, thereby further limiting the magnet 302. After that, the elastic force of the elastic belt 301 is used in conjunction with the airbag 2203 to slowly lower the patient, thereby further reducing the patient's inertia and avoiding the risk of the patient falling out of bed.
