Description

Technical Field

[0001] This invention relates to the field of surgical equipment technology, and in particular to a lateral decubitus fixation device for assisting in turning over. Background Technology

[0002] Intensive care refers to the intensive treatment and nursing care provided to critically ill patients based on the integration of basic and clinical medicine, utilizing advanced medical technologies and modern monitoring and resuscitation equipment to maximize patient survival and subsequent quality of life. Critical care medicine is the theoretical foundation of intensive care unit work, while the intensive care unit is the clinical practice base for critical care medicine.

[0003] The intensive care unit (ICU) primarily admits patients with various critical, acute, and reversible illnesses, such as those requiring monitoring after major surgery, patients with anesthetic accidents, patients with severe complex trauma, acute circulatory failure, acute respiratory failure, patients resuscitated from cardiac and respiratory arrest, patients resuscitated from electric shock or drowning, patients with various poisonings, patients with various types of shock, patients with sepsis, patients with amniotic fluid embolism, and patients with severe preeclampsia. Specialized ICUs admit critically ill patients within their respective specialties; for example, patients with myocardial infarction are admitted to the coronary ICU; patients with extensive burns are admitted to the burn ICU; and patients with various cerebrovascular accidents are admitted to the neurological ICU.

[0004] During the treatment of critically ill patients, medical staff usually need to perform various examinations and treatments on the patients, including not only the front of the patient's body, but also multiple organs on the back, buttocks, and other parts of the patient's body. At the same time, most patients in the intensive care unit are in a coma, and when examining the back of the patient, it is necessary to turn the patient into a side-lying position. Moreover, different examinations and treatments require different side-lying angles. Therefore, it is particularly important to equip the intensive care unit with a side-lying fixation device with an adjustable angle that can assist medical staff in turning patients. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention aims to provide a lateral decubitus fixation device that assists medical staff in turning patients over and allows for multi-angle adjustment. The device combines a fixed plate with a flipping plate, and utilizes a flipping adjustment mechanism at the bottom of the bed to raise the flipping plate to an appropriate angle. Simultaneously, the flipping plate from the patient's back to their thighs is movable, allowing it to be flipped downwards to expose the patient's back and buttocks, facilitating examination and treatment by medical staff. Furthermore, when it is necessary to adjust the patient's lateral decubitus angle, an auxiliary turning mechanism and an auxiliary traction mechanism work together to adjust the angle. Additionally, an arm support mechanism supports and fixes the patient's arms in the lateral decubitus position, and a front support mechanism supports the front of the patient's pelvis, making the patient's lateral decubitus position more stable, thus solving the problems existing in the prior art.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A lateral positioning fixation device for assisting in turning over, characterized in that it includes:

[0008] The bed frame includes a fixed plate and a tilting plate. The fixed plate is connected to the tilting plate along the length of one side, and the tilting plate has a movable plate in the middle.

[0009] Two sets of tilting adjustment mechanisms are symmetrically located at the head and foot of the bed at the bottom of the bed frame, used to adjust the angle of the tilting plate;

[0010] Two sets of auxiliary turning mechanisms are installed at the head and foot of the turning board;

[0011] The arm support mechanism, located at the head end of the fixed board, is used to support the arm of a patient in a lateral decubitus position.

[0012] The front support mechanism is located in the middle of the fixed plate on the side away from the flip plate, and is used to support the front of the pelvis of the patient in the lateral decubitus position.

[0013] To achieve the above objectives, a further preferred embodiment of the present invention is that the bed is also provided with an auxiliary traction mechanism for cooperating with the auxiliary turning mechanism to turn the patient over.

[0014] Furthermore, by adopting the above scheme, each set of tilting adjustment mechanisms includes a power component and a linkage component. The power component is connected to the bottom of the fixed plate, and one end of the linkage component is connected to the bottom of the tilting plate, while the other end is connected to the power component.

[0015] By adopting the above scheme, the power assembly further includes a lead screw and a nut. One end of the lead screw is connected to the output end of the motor, the motor is connected to the bottom of the fixed plate, and the nut is slidably connected to the lead screw.

[0016] By adopting the above scheme, the linkage assembly further includes a first linkage and a second linkage. The first linkage is connected to the bottom of the flip plate, and the second linkage is connected to the nut. The connection between the first linkage and the second linkage is hinged to each other.

[0017] By adopting the above scheme, the two sets of auxiliary turning mechanisms are respectively located at the head end and the foot end of the bed and have the same structure. Each set of auxiliary turning mechanisms includes an adjustment component and a gear assembly. The adjustment component is connected to the gear assembly, and the gear assembly is located at the bottom of the turning plate. The adjustment component includes lead screw two and lead screw three. The upper ends of lead screw two and lead screw three are connected to push handles. The gear assembly includes gear one, gear two and gear three. Gear one and gear two are respectively sleeved on lead screw two and lead screw three and are both meshed with gear three. Gear three is connected to the output end of motor three fixed at the bottom of the turning plate.

[0018] By adopting the above scheme, the arm support mechanism further includes a low arm support and a high arm support, both of which are U-shaped groove structures. The low arm support is connected to the side of the fixed plate away from the flip plate; the high arm support is located above the low arm support, and its bottom is provided with a telescopic cylinder, which is connected to the fixed plate for adjusting the height of the high arm support.

[0019] By adopting the above scheme, the front support mechanism further includes a support plate, a straight rod, and a moving part. The support plate is slidably sleeved on the straight rod. Limiting members are sleeved on both sides of the straight rod along the length of the bed. The moving part is connected to the straight rod and located below the support plate. The moving part includes an arc-shaped rack and a gear four. The gear four is sleeved on the straight rod and meshes with the arc-shaped rack. A motor four is provided at the bottom of the fixed plate. The center of the output shaft of the motor four is located at the center of the arc-shaped rack. The output shaft of the motor four is connected to the bottom of the straight rod through a gear seven and a sprocket.

[0020] By adopting the above scheme, the auxiliary pulling mechanism further includes a drum, an auxiliary belt and a pull rope. The drum is sleeved on the straight rod, the auxiliary belt is connected between the fixed plate and the flipping plate, one end of the pull rope is connected to the upper end of the auxiliary belt, and the other end is wound around the drum.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The bed frame of the present invention is configured as a combination of a fixed plate and a flip plate, so that the flip plate part can be adjusted to the required flip angle under the action of the flip adjustment mechanism at the bottom of the bed frame. At the same time, the middle part of the flip plate is configured as a movable plate, which can be flipped downward so that the back and thighs of the patient in the side-lying position are not obstructed in any way, which makes it convenient for medical staff to perform examinations, treatments and nursing operations on the back or buttocks of the patient in the side-lying position.

[0023] 2. The present invention provides auxiliary turning mechanisms at both the head and foot ends of the turning board, which are used to support and push the patient's back and legs respectively. The auxiliary turning mechanism is configured as a structure of two lead screws cooperating with a nut and gear, and the thread pitch of the outer lead screw two is greater than that of the inner lead screw three, so that the stroke of lead screw two under synchronous rotation is greater than that of lead screw three, which can make the patient rotate and push up to the required lateral lying position angle with the side supported by it.

[0024] 3. The front support mechanism and the auxiliary traction mechanism of the present invention move in a synchronized manner. While the patient is pushed up by the auxiliary turning mechanism, the auxiliary traction mechanism wraps around the patient's waist and hips to further pull the patient up. At this time, the front support mechanism is located on the front side of the patient's pelvis, which can provide better support for the patient's side-lying position.

[0025] 4. The present invention further provides headrests at both ends of the bed and armrests that are symmetrical about the length of the bed, so that both ends of the bed can be used as headboards to meet the needs of patients in different lateral positions (left or right side lying).

[0045] Example 1:

[0046] Reference Figure 1-12This invention provides a side-lying position fixation device for assisting in turning over, including a bed frame 1. The bed frame 1 includes a fixed plate 11 and a tilting plate 12. Support columns 13 are connected to the bottom of the bed frame 1. The support columns 13 include three sets, wherein two sets of support columns 13 connected to the fixed plate 11 are fixed to the bottom of the fixed plate 11 by bolts. The middle part of the support column 13 near the tilting plate 12 is fixedly connected to the middle part of the support column 13 located below the tilting plate 12. When the tilting plate 12 is in a horizontal state, it is placed on top of the support columns 13 to provide support. Figure 1-2 As shown, the fixed plate 11 is connected to the flip plate 12 along the length of one side. The middle part of the flip plate 12 is set as a movable plate 121. The bottom of the movable plate 121 is connected to the flip plate 12 via a hinge 122 and a support plate 123, so that the movable plate 121 can be flipped downward. Specifically, both the fixed plate 11 and the flip plate 12 are provided with sleeves on their near sides. The sleeves are fitted onto the long shaft 14 to connect the fixed plate 11 and the flip plate 12. Meanwhile, the bed body 1 of the present invention does not make any improvements to the patient's headrest. It can adopt the adjustable angle structure design disclosed in the prior art or use a cushion, both of which are suitable for the patient's head comfort when in a side-lying position.

[0047] Furthermore, two sets of tilting adjustment mechanisms 2 are symmetrically arranged at the head and foot ends of the bed frame 1 to adjust the rotation angle of the tilting plate 12. The adjustment range of the angle is 30° to 45°. Each set of tilting adjustment mechanisms 2 includes a power assembly 21 and a linkage assembly 22, specifically:

[0048] like Figure 4 As shown, the power assembly 21 includes a lead screw 211 and a nut 212. The lead screw 211 passes through a mounting groove 111 fixedly connected to the bottom of the fixed plate 11. The nut 212 is slidably sleeved on the lead screw 211 and slides in a direction parallel to the mounting groove 111. A gear 213 is fixedly sleeved at one end of the lead screw 211 located outside the mounting groove 111. A motor 216 is fixedly installed in the middle of the bottom of the fixed plate 11. A gear 214 is provided on the output end of the motor 216. The gear 213 and the gear 214 are connected by a long chain 215. When the motor 216 is started, the output shaft of the motor 216 rotates, driving the two gears 214 sleeved on it to rotate. The gears 214 and the long chain 215 cooperate to drive the gears 213 at both ends to rotate synchronously. The lead screw 211 rotates under the drive of the gears 213, thereby driving the nut 212 to move on the lead screw 211 in a direction parallel to the mounting groove 111.

[0049] like Figure 5As shown, the linkage assembly 22 includes a first linkage 221 and a second linkage 222. The bottom of the flip plate 12 is provided with a fixing block 124. The first linkage 221 is hinged to the bottom of the fixing block 124, and the second linkage 222 is hinged to the bottom of the nut 212. The connection between the first linkage 221 and the second linkage 222 is hinged to each other. With the cooperation of the first screw 211 and the nut 212, the second linkage 222 is pushed to move along the first screw 211 towards the first linkage 221. Under the push of the first linkage 221 on the bottom of the flip plate 12, the flip plate 12 rotates upward at an angle.

[0050] Furthermore, two sets of auxiliary turning mechanisms 3 are provided on the turning board 12, both extending through the head and foot ends of the turning board 12. Specifically, as follows: Figure 2 As shown, the two sets of assisted turning mechanisms 3 adopt the same structural design to push and support the patient's back or legs, wherein:

[0051] like Figure 6 As shown, each auxiliary turning mechanism 3 includes an adjustment component 31 and a gear assembly 32. The adjustment component 31 is movably connected to the gear assembly 32, which is located in a mounting box at the bottom of the turning plate 12. The adjustment component 31 includes a second lead screw 311 and a third lead screw 312, which are respectively inserted into cavities in the turning plate 12. The second lead screw 311 is inserted into the cavity near the outer side of the turning plate 12, and the third lead screw 312 is inserted into the cavity on the inner side. The thread pitch on the second lead screw 311 is greater than that on the third lead screw 312. The upper ends of both the second lead screw 311 and the third lead screw 312 are connected to push handles 313. Specifically, the push handle 313 includes a base 3131 and an arc-shaped push head 3133. The second lead screw 311 and the third lead screw 312 are respectively rotatably connected to the inside of the base 3131 (e.g., ...). Figure 8-9 Specifically, lead screws 311 and 312 are provided with slots 310 on their upper parts. A retaining ring 3130 is fixedly connected inside the base 3131. The slots 310 are engaged in the retaining ring 3130, allowing lead screws 311 and 312 to rotate inside the base 3131. A support seat 3132 is fixedly connected between the top of the base 3131 and the arc-shaped push head 3133. The support seat 3132 has a U-shaped structure and can be made of polyurethane material with high resilience. A spring 3134 is provided between the support seat 3132 and the arc-shaped push head 3133, which can play a buffering role when pushing the patient's back. At the same time, a sponge pad or silicone pad can be fixedly connected inside the arc-shaped push head 3133 to make it more comfortable when it comes into contact with the patient's back.

[0052] The gear assembly 32 includes a first gear 321, a second gear 322, and a third gear 323. The first gear 321 and the second gear 322 are respectively fitted onto the second lead screw 311 and the third lead screw 312. The inner side of the first gear 321 is provided with a thread adapted to the second lead screw 311, and the inner side of the second gear 322 is provided with a thread adapted to the third lead screw 312. Each cavity on the flip plate 12 is provided with a limiting plate that mates with the first gear 321 and the second gear 322, allowing the first gear 321 and the second gear 322 to rotate within the range of their respective limiting plates. The gears 321 and 322 are used to restrict their vertical movement. The outer sides of the gears 321 and 322 mesh with the gear 323. The gear 323 is fixedly connected to the output end of the motor 33. The motor 33 is fixed to the outside of the mounting box at the bottom of the flip plate 12. When the motor 33 is started, the gear 323 rotates synchronously, driving the gears 321 and 322 to rotate. The lead screws 311 and 312, which are respectively engaged with the gears 321 and 322, rotate to push the patient's back and legs upward.

[0053] Before the adjustment component 31 is used to push the patient to turn over further, the push handle 313 is located in the cavity opened in the flip plate 12 and will not press against the patient's back to cause discomfort.

[0054] Furthermore, an arm support mechanism 4 is provided at the head end of the fixed plate 11 to support the arm of the patient in a lateral decubitus position. Specifically, as shown in the figure... Figure 2 As shown, the arm support mechanism 4 includes a low arm support and a high arm support, both of which are U-shaped groove structures. The patient's two arms can be placed on the low arm support and the high arm support respectively, and secured with straps as needed. The low arm support includes a support plate 41, which is hinged to the outer side of the fixing plate 11 along its length and is horizontally positioned with a groove on the fixing plate 11. The groove matches the position of the patient's arm and is used to support the lower arm when the patient is in a side-lying position. The support plate 41 is connected to the groove at the point furthest from the arm. The end of one side of the flip plate 12, which is slightly higher than the groove, allows the patient's arm tip to be slightly higher when lying on their side, preventing poor blood circulation in the arm tip and insufficient blood supply to the hand. The high arm support is connected to the side of the fixed plate 11 and is located above the low arm support. Its bottom is an adjustable telescopic cylinder 43, the bottom of which is connected to the fixed plate 11. Above the telescopic cylinder 43 is a rotatable support plate 42, which can be rotated to be parallel or perpendicular to the length of the bed 1 as needed.

[0055] Furthermore, a front support mechanism 5 is provided in the middle of the side of the fixation plate 11 away from the flipping plate 12, for supporting the anterior side of the pelvis of the patient in the lateral decubitus position, such as... Figure 1-2 , Figure 7As shown, specifically: the front support mechanism 5 includes a support plate 51, a straight rod 52, and a moving part 53. A sleeve is connected to the rear side of the support plate 51, allowing it to slidably mount on the straight rod 52. The straight rod 52 is inserted into a curved groove in the fixed plate 11 that tightly fits the straight rod 52. Limiting members are sleeved on both sides of the straight rod 52 along the length of the bed 1. The bottom of the limiting members slides within the arc-shaped grooves of the fixed plate 11 on both sides of the straight rod 52. Specifically, the arc-shaped grooves are T-shaped, allowing the bottom of the limiting members to engage with the T-shaped structure of the arc-shaped grooves. The moving part 53 is connected to the straight rod 52 and located below the support plate 51, wherein:

[0056] like Figure 7 As shown, the moving part 53 includes an arc-shaped rack 531 and a gear 532. The arc-shaped rack 531 is formed on one side of the curved groove in the middle of the fixed plate 11, and the curved groove and the arc-shaped rack 531 are concentric and have the same curvature. The gear 532 is sleeved on the straight rod 52 and meshes with the arc-shaped rack 531. A motor 54 is fixedly connected to the bottom of the fixed plate 11, and the center of the output shaft of the motor 54 is located at the center of the arc-shaped rack 531. The output shaft of the motor 54 and the bottom of the straight rod 52 rotate in cooperation with the sprocket 56 through the gear 55 connected on both. This ensures that the straight rod 52 and the arc-shaped rack 531 always move within the radius of the arc-shaped rack 531. When the motor 54 is started, its gear 55, the gear 55 at the bottom of the straight rod 52, and the sprocket 56 work together to drive the straight rod 52 to rotate. At the same time, the gear 532 on the straight rod 52 works with the arc-shaped rack 531 to move forward, driving the support plate 51 to a position suitable for the lateral decubitus patient and stopping. After the support plate 51 is moved to a suitable height on the straight rod 52, it is supported on the front of the patient's pelvis to further stabilize the lateral decubitus patient.

[0057] Example 2:

[0058] Normally, when a patient is adjusted from a supine to a lateral position, medical staff need to assist by applying force to their back and waist. Based on the above embodiment 1, in order to further reduce the workload of medical staff and to work with the auxiliary turning mechanism 3 and the front support mechanism 5 to pull the patient to a suitable lateral angle and fix them, an auxiliary traction mechanism 6 is added between the fixed plate 11 near the turning plate 12 and the front support mechanism 5. This can further provide a wrapping traction to the patient's waist and hips, thereby working with the auxiliary turning mechanism 3 to help the patient reach the required lateral angle.

[0059] like Figure 10-11As shown, the auxiliary traction mechanism 6 includes a drum 61, an auxiliary belt 62, and a pull rope 63. The drum 61 is sleeved on the straight rod 52 and is used to wrap one end of the pull rope 63. The auxiliary belt 62 is made of nylon or fiber fabric. The bottom end of the auxiliary belt 62 is connected to the long shaft 13 between the fixed plate 11 and the flip plate 12 and is used to wrap around the back of the patient's waist and hips. Its upper end is provided with a hook and pull ring, which can be connected to the hook at the other end of the pull rope 63. When the straight rod 52 rotates, it can wind one end of the pull rope 63 onto the drum 61, so that the patient can be pulled to the required lateral lying position angle with the cooperation of the auxiliary belt 62, the pull rope 63, and the straight rod 52.

[0060] Example 3:

[0061] Based on the above embodiments one and two, in order to make the bed 1 more practical, the structure of the bed 1 is further improved as follows to meet the needs of patients in two different lateral decubitus positions, left and right.

[0062] With other structural elements remaining unchanged in the two embodiments described above, a headrest identical to that at the head of the bed is provided at the foot of the bed, and an armrest mechanism 4 with the same structure and function as that at the head of the bed is provided at the original foot of the bed. The improved overall structure is as follows: Figure 12 As shown, this structure can be used to assist patients in turning over when they are in a left or right lateral decubitus position. Simply select the occiput position according to the direction of turning over during treatment.

[0063] In practical use, the lateral recumbent position fixation device of the present invention is as follows: The patient lies flat on the bed 1 according to the required lateral recumbent angle. First, motor 216 is started, simultaneously driving the tilting adjustment mechanism 2 at the head and foot of the bed, causing the tilting plate 12 to rotate and adjust the patient to a suitable angle. Motor 216 then stops working. Next, motor 33 is started, causing lead screws 311 and 312 to extend from the cavities at the head and foot of the tilting plate 12 at different heights, acting on the patient's back and legs to push the patient to the position required by the medical staff. At the same time, start motor 4 54, so that when the straight rod 52 rotates and pulls the auxiliary belt 62 and the pull rope 63, it moves synchronously towards the direction of the patient. When the patient is pulled to the required angle, stop motor 3 33 and motor 4 54. Then, place the patient's lower arm on the support plate 1 41 of the low arm rest and place the patient's upper arm on the support plate 2 42 of the high arm rest. Finally, flip the movable plate 121 in the center of the flip plate 1 downward to fully expose the patient's waist and buttocks, so that medical staff can carry out the corresponding treatment and care for the patient.

[0064] The foregoing description illustrates the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
