Description

Technical Field

[0001] This invention relates to the field of patient restraint, specifically to a multifunctional patient restraint strap fixation device for operating room care. Background Technology

[0002] Operating room nursing is a professional nursing service provided to patients during surgery and resuscitation, and it is an important part of hospital nursing work. To improve the safety of operating room nursing, restraint straps are used to restrain patients. To enhance the restraint effect, restraint strap fixing devices are needed. The "Multifunctional Automatic Adjustment Device for Restraint Straps for Psychiatric Patients" disclosed in application number "202510343758.3" is an increasingly mature technology. This invention, through the setting of a take-up roller, an internal hexagonal threaded plug, an annular plate, a circular plate, and an mounting sleeve, provides support for restraining psychiatric patients. Two support rods are fixedly connected to the outer side of the circular plate. A fixing plate is fixedly connected to the external bed frame with fixing bolts, thus supporting and fixing the circular plate. A T-shaped plate is slidably installed inside the take-up roller, limited by the internal hexagonal threaded plug. Then, a second strap is fastened inside the connector, limited by a baffle for easy disassembly. The C-shaped restraint plates at both ends of the second strap are fastened to the patient's legs. The device uses a forward and reverse motor to wind up the first pull strap, and the length of the first pull strap is adjusted according to the patient's height. However, this adjustment device has the following drawbacks: While the T-shaped plate, in conjunction with the winding roller, support rod, first pull strap, and second pull strap can indeed restrain the patient's legs, this structure only restrains the patient's legs and is not very effective at restraining the patient's hands. Furthermore, it is inconvenient to use with different hospital beds. Therefore, it is necessary to provide a fixation device that can easily restrain the patient's upper and lower limbs and enhance versatility. In addition, this adjustment device is not convenient for restraining different parts of the patient's body and the comfort is not significant. Therefore, it is necessary to provide a fixation device that can easily restrain different parts of the patient's body and improve comfort. Also, this adjustment device is not convenient for height adjustment as needed, thus affecting the ease of use. Therefore, it is necessary to provide a fixation device that is height-adjustable and improves ease of use. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. When simultaneously restraining and limiting the patient's upper and lower limbs, first guide the patient to lie on the upper part of the bed board. Then, install the mounting plate on both sides of the bed board, with two clamps located at the upper and lower ends of the bed board. Then, tighten the third bolt. With the help of the first guide rod, the two clamps can be controlled to rise and fall along the third bolt to clamp and fix the bed board, so that the leg restraint assembly can be used for different hospital beds. The presence of the anti-slip plate can enhance the installation stability of the leg restraint strap. Then, simply wrap the leg restraint strap around the patient's legs. At this time, the Velcro and Velcro are glued together to restrain the patient's legs. At the same time, wrap the hand restraint strap around the mounting rod, and then wrap the wristband around the patient's wrist to protect it. At the same time, wrap the hand restraint strap around the wristband. According to the size of the patient's wrist, insert the pin into one of the pin holes to limit the patient's upper limbs through the wristband and hand restraint strap. Compared with the restraint strap adjustment device in the existing technology "A Multifunctional Psychiatric Patient Restraint Strap Automatic Adjustment Device", the present invention can restrain the patient's upper and lower limbs through the above structure and is suitable for use in different hospital beds, thus significantly enhancing the versatility of the fixation device.

[0020] 2. When restraining the patient's body at different positions, the first transmission mechanism is activated to rotate the first reciprocating screw. This, combined with the mounting rod, controls the two limiting shafts to move closer or further apart along the first reciprocating screw and the fixing rod. When the two limiting shafts move further apart, the adjusting block sleeved on the side surface of the limiting shaft stretches the restraint spring, facilitating the adjustment of the position of the abdominal limiting plate. When the abdominal limiting plate is in different positions on the patient's body, an external power source can be used to energize the heating grid, heating the abdominal massage pad and providing heat therapy to the patient. Simultaneously, ventilation holes facilitate airflow, and the massage heads on the surface of the abdominal massage pad provide massage to the patient's body. Finally, a temperature controller adjusts the temperature of the abdominal massage pad. Compared to the adjustment device in the existing "Multifunctional Automatic Adjustment Device for Psychiatric Patient Restraint Belt," this invention, through the coordinated structure described above, not only facilitates restraint at different positions on the patient's body but also enables heat therapy and massage, thereby enhancing the versatility and comfort of the restraint device.

[0021] 3. When adjusting the height of the fixing device, the second transmission mechanism is first activated to rotate the second reciprocating screw clockwise or counterclockwise. This, combined with the second guide rod, controls the two first sliders on the side surfaces to move closer or further apart. Simultaneously, the second sliders move closer or further apart along the positioning rod. This controls the relative rotation of the first and second inclined plates on both sides, allowing for adjustment of the angle between them, thus facilitating the adjustment of the bed board height. The self-locking casters also allow the fixing device to be moved and used. Compared to the adjustment device in the existing "Multifunctional Automatic Adjustment Device for Psychiatric Patient Restraint Belts," this invention, through the cooperation of the above structures, facilitates height adjustment as needed, thereby improving the ease of use of the fixing device.

The surface of the second restraint strap 105 has several connecting grooves 108 spaced equidistantly. Several connecting blocks 109 are hinged to the side surface of the abdominal limiting plate 102. Two restraint springs 110 are detachably mounted on the surface of each connecting block 109. An adjustment block 120 is detachably installed at the end of the tension spring 110. An abdominal massage pad 130 is embedded at the lower end of the abdominal limiting plate 102. An electric heating grid 140 is installed inside the abdominal massage pad 130. A temperature controller 150 is installed at the upper end of the abdominal limiting plate 102. Guide grooves 160 are opened on both sides of the bed board 101. A first reciprocating screw 170 and a fixed rod are rotatably connected inside the two guide grooves 160 respectively. Two limiting shafts 180 are sleeved on the side surfaces of the first reciprocating screw 170 and the fixed rod. A first transmission mechanism 190 is installed at one end of the first reciprocating screw 170. Several massage heads 1300 are provided on the surface of the abdominal massage pad 130.

[0036] The hand restraint assembly 200 includes mounting rods 201 installed on both sides of one end of the bed board 101. A hand restraint strap 202 is wrapped around the side surface of the mounting rods 201. A plurality of pin holes 203 are equidistantly opened on the surface of the hand restraint strap 202. A pin head 204 is connected to one end of the hand restraint strap 202. A wrist guard 205 is detachably installed on the surface of the hand restraint strap 202.

[0037] The leg restraint assembly 300 includes mounting plates 301 installed on both sides of the other end of the bed board 101. Two clamps 302 are detachably installed on the surface of the mounting plates 301. Anti-slip plates 303 are embedded on the opposite sides of the two clamps 302. A third bolt 304 and a first guide rod 305 are rotatably connected inside the mounting plates 301. A leg restraint strap 306 is provided on the back of the mounting plates 301. A barbed Velcro 307 and a hook-and-loop Velcro 308 are respectively installed on both sides of the leg restraint strap 306.

[0038] The lifting assembly 400 includes a movable plate 401. The upper end of the movable plate 401 is rotatably connected to a second reciprocating screw 402 and a second guide rod 403. A second transmission mechanism 404 is installed at one end of the second reciprocating screw 402. The upper ends of the movable plate 401 are hinged to a first inclined plate 405 and a second inclined plate 406. Positioning rods 407 are inserted into the interior of the first inclined plate 405 and the second inclined plate 406. Several self-locking casters 408 are detachably installed at the lower end of the movable plate 401.

[0039] In one specific embodiment, the abdominal restraint component 100, hand restraint component 200, leg restraint component 300, and lifting component 400 not only facilitate the adjustment of the height of the fixation device and its movement as needed, thus significantly improving the ease of use of the fixation device, but also, through the cooperation of the above structures, facilitate the simultaneous restraint of the patient's upper and lower limbs. Furthermore, it is applicable to different hospital beds, thereby enhancing the versatility of the fixation device. Additionally, the cooperation of the above structures facilitates the restraint of different parts of the patient's body and the application of massage and heat therapy, thus improving the practicality and comfort of the fixation device. In use, the second transmission mechanism 404 is first activated to drive the second reciprocating... The screw 402 rotates clockwise or counterclockwise, cooperating with the second guide rod 403 to control the two first sliders 412 on the side surfaces to move closer or further apart, while the second sliders 414 move closer or further apart along the positioning rod 407. This controls the relative rotation of the first inclined plates 405 and the second inclined plates 406 on both sides, thereby adjusting the angle between them to adjust the height of the bed board 101. The self-locking casters 408 allow the fixing device to be moved, improving its ease of use. When restraining the patient's upper and lower limbs, the patient is first guided to lie on the upper part of the bed board 101, and the mounting plates 301 are installed on both sides of the bed board 101. At the same time, the two clamping plates 302 are located on the upper and lower sides of the bed board 101. Tightening the third bolt 304, in conjunction with the first guide rod 305, controls the two clamping plates 302 to rise and fall along the third bolt 304, clamping and fixing the bed board 101. This allows the leg restraint assembly 300 to be used with different hospital beds. Finally, simply wrap the leg restraint strap 306 around the patient's legs, and simultaneously attach the Velcro 307 and Velcro 308 to each other to restrain the patient's legs. Simultaneously, wrap the hand restraint strap 202 around the mounting rod 201, and then wrap the wrist brace 205 around the patient's wrist for protection. The hand restraint strap 202 is also wrapped around the wrist brace 205. Based on the patient's wrist size, the pin head 204 is inserted into one of the pin holes 203, thus allowing the wrist brace 205 and hand restraint strap 202 to restrain the patient's legs. The upper limbs are restricted to enhance the versatility of the fixation device. Then, the first transmission mechanism 190 is activated, rotating the first reciprocating screw 170. This, in conjunction with the mounting rod 201, controls the two limiting shafts 180 to move closer or further apart along the first reciprocating screw 170 and the fixing rod. When the two limiting shafts 180 move further apart, the adjusting block 120, sleeved on the side surface of the limiting shaft 180, stretches the constraint spring 110, thereby adjusting the position of the abdominal limiting plate 102. When the abdominal limiting plate 102 is in different positions on the patient's body, an external power source powers the heating grid 140, heating the abdominal massage pad 130 for heat therapy. Simultaneously, the vent 103 facilitates ventilation.Meanwhile, the massage heads 1300 on the surface of the abdominal massage pad 130 can massage the patient's body. Finally, the temperature of the abdominal massage pad 130 is adjusted by the temperature controller 150, thereby improving the comfort and practicality of the fixation device.

[0040] Please see Figures 2-4 The first transmission mechanism 190 includes a first motor 1901 mounted on the lower end of the bed board 101, a first synchronous pulley 1902 mounted on the output end of the first motor 1901, a second synchronous pulley 1903 mounted on one end of the first reciprocating screw 170, and a synchronous belt 1904 connected between the first synchronous pulley 1902 and the second synchronous pulley 1903.

[0041] In one specific embodiment, by starting the first motor 1901 to rotate the first synchronous pulley 1902, the synchronous belt 1904 can rotate the second synchronous pulley 1903, which in turn can rotate the first reciprocating screw 170, thus enabling the adjustment of the positions of the two limit shafts 180.

[0042] Please see Figures 2-4 A sliding block 111 is fixedly connected to the surface of the limiting shaft 180. The first reciprocating screw 170 and the fixing rod are both inserted into the sliding block 111. Several hinge seats 112 are installed at the lower end of the bed board 101, and the positioning rod 407 is inserted into the hinge seat 112.

[0043] In one specific embodiment, controlling the sliding block 111 to move along the first reciprocating screw 170 can improve the smoothness of movement, and the hinge seat 112 can improve the installation stability of the positioning rod 407.

[0045] In one specific embodiment, the hinge shaft 123 is hinged inside the hinge piece 122, thereby improving the smoothness of the connection between the connecting block 109 and the abdominal limiting plate 102, and thus improving the ease of use.

[0046] Please see Figures 2-4Two positioning holes 131 are provided on both sides of the abdominal limiting plate 102. Two positioning blocks 132 are fixedly connected to one end of the first constraint band 104 and the second constraint band 105. The two positioning blocks 132 are snapped into the inside of the positioning holes 131. The two ends of the constraint spring 110 are fixedly connected to the first bolt 133. The first bolt 133 is threaded into the inside of the connecting block 109 and the adjusting block 120.

[0047] In one specific embodiment, the positioning block 132 is snapped into the positioning hole 131, so the patient's body can be wrapped and restrained as needed by the first restraint band 104 and the second restraint band 105. The first bolt 133 is threaded into the connecting block 109 and the adjusting block 120, which can improve the connection stability between the restraint spring 110 and the ease of disassembly and replacement.

[0048] Please see Figure 5 and Figure 6 The hand restraint strap 202 has an installation block 211 inside, and the wrist guard 205 has a locking block 212 fixedly connected to the back, which is engaged inside the installation block 211.

[0049] In one specific embodiment, the locking block 212 is engaged inside the mounting block 211, which can improve the connection stability and ease of disassembly and replacement between the wristband 205 and the hand restraint strap 202.

[0050] Please see Figure 5 and Figure 6 Both ends of the mounting rod 201 are fixedly connected to the screw tube 221. A hexagonal shaft 222 is inserted into the inside of the hexagonal hole 121. A second bolt 223 is fixedly connected to one end of the hexagonal shaft 222. The second bolt 223 is threaded into the inside of the screw tube 221.

[0051] In one specific embodiment, the hexagonal shaft 222 is inserted into the hexagonal hole 121, which can improve the ease of disassembly and assembly of the mounting rod 201 and the bed plate 101. The second bolt 223 is threaded into the screw tube 221, which can improve the ease of disassembly and assembly of the mounting rod 201 and the hexagonal shaft 222.

[0052] Please see Figures 7-9 Both sides of the leg restraint strap 306 are provided with fitting grooves 311. The hook and loop fasteners 307 and the hook and loop fasteners 308 are installed inside the fitting grooves 311. The clamp plate 302 is fixedly connected to one side with an ear block 312. The third bolt 304 and the first guide rod 305 are inserted into the ear block 312. The surface of the clamp plate 302 is provided with an installation groove 313. The anti-slip plate 303 is installed inside the installation groove 313.

[0053] In one specific embodiment, the fitting groove 311 can improve the installation stability of the barbed hook and loop fastener 307 and the rough hook and loop fastener 308. The third bolt 304 is inserted into the ear block 312. By turning the third bolt 304, the two clamps 302 can be controlled to move closer or further apart in conjunction with the first guide rod 305, so that the leg restraint assembly 300 can be used in different hospital beds.

[0054] Please see Figures 7-9 The second transmission mechanism 404 includes a first transmission disc 4041 installed at one end of the second reciprocating screw 402, a second motor 4042 installed at the upper end of the moving plate 401, a second transmission disc 4043 installed at the output end of the second motor 4042, and a transmission belt 4044 connecting the first transmission disc 4041 and the second transmission disc 4043.

[0055] In one specific embodiment, by starting the second motor 4042 to rotate the second transmission disk 4043, the transmission belt 4044 can rotate the first transmission disk 4041, which in turn can rotate the second reciprocating screw 402. With the help of the second guide rod 403, the first slider 412 can be moved, thereby adjusting the angle between the first inclined plate 405 and the second inclined plate 406, so as to adjust the height of the fixing device.

[0056] Please see Figures 7-9 The upper end of the movable plate 401 has two slide grooves 411. The second reciprocating screw 402 and the second guide rod 403 are rotatably connected inside the two slide grooves 411. The lower ends of the first inclined plate 405 and the second inclined plate 406 are hinged to the first slider 412. The two first sliders 412 are rotatably connected to the transmission rod 413. The upper ends of the first inclined plate 405 and the second inclined plate 406 are hinged to the second slider 414. The positioning rod 407 is inserted into the second slider 414.

[0057] In one specific embodiment, when the second reciprocating screw 402 rotates, the first slider 412 rotates along the slide groove 411, and in conjunction with the second guide rod 403, the angles of the first inclined plate 405 and the second inclined plate 406 can be adjusted.

[0058] Working principle: In use, the second transmission mechanism 404 is activated first, causing the second reciprocating screw 402 to rotate clockwise or counterclockwise. This, combined with the second guide rod 403, controls the two first sliders 412 on their side surfaces to move closer or further apart. Simultaneously, the second sliders 414 move closer or further apart along the positioning rod 407, controlling the relative rotation of the first inclined plates 405 and second inclined plates 406 on both sides. This allows for adjustment of the angle between them, thereby adjusting the height of the bed board 101. The self-locking casters 408 enhance the ease of use of the fixing device by allowing it to be moved around, facilitating patient movement. When restraining the limbs, first guide the patient to lie on the upper part of the bed board 101. Simultaneously, install the mounting plate 301 on both sides of the bed board 101. Two clamping plates 302 are positioned at the upper and lower ends of the bed board 101, and the third bolt 304 is tightened. With the first guide rod 305, the two clamping plates 302 can be raised and lowered along the third bolt 304 to clamp and fix the bed board 101, thus making the leg restraint assembly 300 suitable for different hospital beds. Finally, simply wrap the leg restraint strap 306 around the patient's legs, and simultaneously attach the hook and loop fasteners 307 and velvet fasteners 308 together to restrain the patient's legs. At the same time, wrap the hand restraint strap 202 around... The wrist brace 205 is wrapped around the patient's wrist via the mounting rod 201 for protection. Simultaneously, the hand restraint strap 202 is wrapped around the wrist brace 205, and the pin 204 is inserted into one of the pin holes 203 according to the patient's wrist size. This allows the wrist brace 205 and hand restraint strap 202 to limit the patient's upper limb, thereby enhancing the versatility of the fixation device. Then, the first transmission mechanism 190 is activated, rotating the first reciprocating screw 170. In conjunction with the mounting rod 201, this controls the two limiting shafts 180 to move closer or further apart along the first reciprocating screw 170 and the fixing rod. When the two limiting shafts 180 move further apart, the restraint strap 202 is wrapped around the limiting shaft 180. The adjustment block 120 on the side surface stretches the restraint spring 110 away, thereby adjusting the position of the abdominal limiting plate 102. When the abdominal limiting plate 102 is in different positions on the patient's body, the heating grid 140 is energized by an external power source, thus heating the abdominal massage pad 130 to facilitate heat therapy on the patient's body. At the same time, the vent 103 facilitates ventilation. The massage head 1300 on the surface of the abdominal massage pad 130 can massage the patient's body. Finally, the temperature of the abdominal massage pad 130 is adjusted by the temperature controller 150, thereby improving the comfort and practicality of the fixation device.
