Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of turning-over assisting devices, in particular to a turning-over assisting device for bedridden patients. BACKGROUND

[0002] Postoperative patients need a period of bed rest to promote wound healing. However, long-term bed rest of patients can also bring a series of complications, such as pressure sores, hypostatic pneumonia, deep vein thrombosis of lower extremity, muscle atrophy and joint stiffness, etc. In order to solve the contradiction between bed rest and complications, the clinical nursing standard requires that the postoperative patients be turned over regularly, which is one of the key basic nursing measures to prevent pressure sores, hypostatic pneumonia and promote blood circulation.

[0003] For some special patients, especially for bedridden patients after neck surgery, the turning-over operation has special requirements. During the turning-over process, the neck and body must be kept in a relatively static state to prevent excessive activity of the neck from causing damage to the surgical site, internal fixation failure or neurovascular complications. However, many existing turning-over assisting devices lack effective support and fixation design for the patient's neck during operation, which makes the trunk and head-neck of the patient prone to unsafe relative twisting during the turning-over process, which poses a significant risk of causing secondary injury to the neck or aggravating the original condition.

Detailed Implementation

[0029] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "forward" and "backward" are used to describe the drawings and not to indicate a limitation on the scope of the invention. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0030] When turning over patients after neck surgery, existing turning devices lack fixation for the patient's head, which can easily lead to the head and body rotating relative to each other during the turning process, resulting in secondary damage to the bellows.

[0031] Example 1: A turning assist device for bedridden patients, such as Figures 1-10 As shown, the bed includes a bed frame 1, which has a headboard and a footboard. Symmetrically distributed mounting brackets 2 are installed on the bed frame 1. The mounting brackets 2 are slidably connected to lifting brackets 3. A motor 4 is fixedly connected to the mounting brackets 2. A lead screw 5 is fixedly connected to the output shaft of the motor 4. The lead screw 5 is rotatably connected to the adjacent mounting bracket 2. The lead screw 5 is threadedly connected to the adjacent lifting bracket 3. Symmetrically distributed sliding brackets 6 are slidably connected to the lifting brackets 3. A rotating shaft 7 is fixedly connected to the sliding brackets 6. A push plate 8 is rotatably connected to the rotating shaft 7. Symmetrically distributed first electric push rods 9 are fixedly connected to the lifting brackets 3. The telescopic end of the first electric push rod 9 is fixedly connected to the corresponding sliding bracket 6. A connecting rod 10 is rotatably connected to the rotating shaft 7 near the headboard of the bed frame 1. A fixing bracket 11 is splined connected to the connecting rod 10. The fixing bracket 11 is used to fix the patient's head.

[0032] Furthermore, such as Figures 2-6 and Figure 10 As shown, the fixing frame 11 is composed of L-shaped rods and arc-shaped plates. The distance between the arc-shaped plates on the symmetrically distributed fixing frame 11 gradually increases from the edge to the center. The L-shaped rods of the fixing frame 11 are telescopic rods. The fixing part of the L-shaped rods of the fixing frame 11 is threadedly connected to a drive rod. This drive rod is used to adjust the position of the telescopic part of the L-shaped rods on the fixing frame 11.

[0033] The above scheme provides a way to keep the patient's neck stable during the process of turning over in the patient's body; in this paper, the head of the bed 1 is located on the right side, that is, the patient's head is right when lying on the bed 1, the mounting frame 2 is two front and back symmetrical distribution, both located in the right part of the bed 1, initially, the lifting frame 3 is located in the lower part of the mounting frame 2, the motor 4 drives the lifting frame 3 to move up and down through the lead screw 5, the position of the lifting frame 3 and its upper parts in the following side is described, one lifting frame 3 has two symmetrical sliding frames 6, the number of sliding frames 6 can be adjusted according to the actual situation, the rotating shaft 7 is located in the front side of the corresponding sliding frame 6, the upper side of the push plate 8 is provided with an inclined surface, the thickness of the push plate 8 gradually decreases from back to front, which is used to facilitate the movement of the push plate 8 to the lower side of the patient, one lifting frame 3 has two first electric push rods 9 which are symmetrically distributed, the first electric push rod 9 is used to drive the sliding frame 6 to move forward and backward, the first electric push rod 9 is a multi-stage push rod, the extension end is in the initial state, the connecting rod 10 is located on the right rotating shaft 7, the fixed frame 11 is located on the right part of the connecting rod 10, the L-shaped rod on the fixed frame 11 is located in the rear part of the arc plate, the fixed frame 11 clamps the patient's head through the arc plate, in the process of pushing the patient to rotate, the patient's head and body keep relatively static, the drive rod of the L-shaped rod on the fixed frame 11 is used to adjust the overall length of the fixed frame 11, so that the overall length of the fixed frame 11 is adapted to the shoulder width of the patient.

[0034] Workflow: when the patient needs to turn over forward, the staff rotates the drive rod in the fixed frame 11 according to the patient's body characteristics, so that the overall length of the fixed frame 11 is adapted to the shoulder width of the patient, then starts the first electric push rod 9 on the two lifting frames 3, the extension end of the first electric push rod 9 is retracted and drives the sliding frame 6 to move, the sliding frame 6 drives the push plate 8 and the connecting rod 10 to move through the rotating shaft 7, the push plate 8 gradually extends into the lower side of the patient, the connecting rod 10 drives the fixed frame 11 to move and gradually approaches the patient's head, after the edge of the front (rear) side of the push plate 8 is flush with the edge of the front (rear) side of the patient's body, the fixed frame 11 contacts the patient's head and completes the fixation, the first electric push rod 9 is closed, the sliding frame 6 stops moving, then the rear motor 4 is started, the rear motor 4 drives the lifting frame 3 and its parts to move upward through the lead screw 5, the rear push plate 8 pushes the patient's body to rotate upward, so that the patient's body rotates along the front side, when the rear motor 4 is started, the rear first electric push rod 9 is started again, so that the rear push plate 8 and the fixed frame 11 move forward and upward with the patient's body, the rear connecting rod 10 and the fixed frame 11 rotate clockwise around the adjacent rotating shaft 7 Figure 1 , seen from left to right), in this process, the front fixed frame 11 and its parts rotate clockwise around the rotating shaft 7 Figure 1(see from left to right), ensure that the patient's head moves stably with the body, until the patient's body is turned to the appropriate angle, the opened electrical components are closed, and the staff supports the patient's back through the existing triangular pad.

[0035] Further, as shown in Figures 2-6 and Figure 10 , the fixed frame 11 is fixedly connected with a guide plate 1101, the guide plate 1101 is fixedly connected with a positioning rod 1102, the guide plate 1101 is provided with a blind hole, and the position of the positioning rod 1102 corresponds to the position of the blind hole on the other guide plate 1101. The blind hole on the guide plate 1101 is used to fix the corresponding positioning rod 1102 on the other guide plate 1101.

[0036] Further, as shown in Figures 2-6 and Figure 10 , the fixed frame 11 is fixedly connected with a soft pad 12, the thickness of the soft pad 12 gradually decreases from the upper side to the middle, and the soft pad 12 is fixedly connected with a fixed strip 13 which is uniformly distributed.

[0037] Further, as shown in Figures 3-6 and Figure 10 , the fixed frame 11 is rotatably connected with a threaded rod 14, and the threaded rod 14 is threadedly connected with the connecting rod 10.

[0038] In the above scheme, the guide plate 1101 is located on the right side of the upper side of the fixed frame 11. During the process of the two connecting rods 10 approaching each other, the guide plate 1101 drives the positioning rod 1102 thereon to move, so that the positioning rod 1102 is inserted into the corresponding blind hole on the other guide plate 1101. Until the facing surfaces of the two guide plates 1101 contact, the positions of the two connecting rods 10 are fixed, avoiding the change of the relative positions of the two connecting rods 10 during the process of the connecting rod 10 turning over the patient's head, which affects the stability of the patient's head position; the material of the soft pad 12 is used to increase the contact area between the soft pad 12 and the patient's head during the process of fixing the patient's head, thereby improving the stability of the patient's head during the moving process. All the fixed strips 13 on the same soft pad 12 are uniformly distributed left and right, and the fixed strips 13 are used to increase the roughness of the surface of the soft pad 12, thereby reducing the probability of relative sliding between the soft pad 12 and the patient's head; the threaded rod 14 is used to adjust the relative position between the fixed frame 11 and the patient's head, so as to facilitate the fixed frame 11 to clamp the patient's head. Initially, the upper side of the connecting rod 10 is in contact with the fixed frame 11.

[0039] Embodiment 2: based on embodiment 1, as shown in Figures 2-7 , Figure 9 and Figure 10As shown, the sliding frame 6 is fixed with a second electric push rod 15, the telescopic end of the second electric push rod 15 is fixed with a limiting frame 16, the telescopic end of the second electric push rod 15 penetrates through the sliding frame 6, the limiting frame 16 is slidingly connected with the adjacent lifting frame 3, the limiting frame 16 close to the connecting rod 10 is fixed with a limiting plate 17, the side of the connecting rod 10 away from the adjacent second electric push rod 15 is fixed with a positioning block 18, and the limiting plate 17 is used to limit the position of the adjacent positioning block 18.

[0040] The above scheme provides a way to limit the position of the connecting rod 10, so that the fixed frame 11 remains stable during movement. Figure 5 For example, the position of the parts, the second electric push rod 15 is located at the rear of the sliding frame 6, the limiting frame 16 is composed of a round rod and an L-shaped plate, the round rod is located at the rear side of the L-shaped plate, the horizontal part of the L-shaped plate on the limiting frame 16 is located at the front side of the vertical part, the telescopic end of the second electric push rod 15 is fixed with the round rod of the limiting frame 16, the limiting plate 17 is located on the limiting frame 16 on the right side in the same mounting frame 2, and the positioning block 18 is located on the front side of the left part of the connecting rod 10. Initially, the upper side of the limiting plate 17 is in contact with the lower side of the positioning block 18, so that the connecting rod 10 cannot drive the parts on it to rotate clockwise (from left to right), and thus the fixed frame 11 and the parts on it remain stable during the process of approaching the patient's head. Figure 1 During the process of the rear side push plate 8 driving the patient's body to turn over, the telescopic end of the rear side second electric push rod 15 drives the limiting frame 16 to move backward, so that the limiting frame 16 releases the limiting of the positioning block 18, thereby enabling the rear side connecting rod 10 to drive the parts on it to rotate around the rotating shaft 7 during the patient's turning over.

[0041] The existing device mostly only lifts one side of the patient's body when turning over the patient's body, which will cause the other side of the patient's body that is not lifted to lack support, so that the patient's body may slip during the turning over process due to gravity, affecting the normal turning over of the patient.

[0043] Further, as shown in Figures 2-5 and Figure 7 and Figure 9 The rotating shaft 7 is rotatably connected with a positioning plate 19, the positioning plate 19 is rotatably connected with the adjacent push plate 8, the positioning plate 19 is slidingly connected with a sliding plate 20, a first spring 21 is fixed between the adjacent positioning plate 19 and the sliding plate 20, the sliding plate 20 is hingedly connected with a fixed plate 22, and a torsional spring 23 is fixed between the fixed plate 22 and the sliding plate 20.

[0048] The above scheme provides a way to support the patient's body and increase the stability of the patient's body during the patient's turning over; in this paper, the same push plate 8 has two adjusting rods 25, which are respectively located on the left and right sides of the positioning plate 19, for increasing the stability of the positioning plate 19 when it rotates relative to the push plate 8, the guide groove on the positioning plate 19 and the parts in it are both two, the push plate 8 is provided with an avoiding groove, which is used for avoiding the positioning plate 19 and the parts on it during the counterclockwise rotation of the push plate 8 relative to the positioning plate 19 (from front to back), the push plate 8 avoids the positioning plate 19 and the parts on it through the avoiding groove thereon, initially, the adjusting rod 25 is located at the lower part of the guide groove of the positioning plate 19, when the push plate 8 rotates counterclockwise relative to the positioning plate 19, the adjusting rod 25 moves upward along the guide groove of the positioning plate 19 and compresses the second spring 27 through the limiting block 26, the limiting block 26 is located at the upper part of the adjusting rod 25, the lower side of the limiting block 26 is in contact with the adjusting rod 25, for ensuring that the adjusting rod 25 can normally rotate and adjust its angle during the relative rotation of the push plate 8 and the positioning plate 19, and the second spring 27 is always in a force storage state, for pushing the adjusting rod 25 to move and reset through the limiting block 26. Figure 8

[0049] Work flow: when the patient needs to turn over, taking the patient turning over from back to front as an example, the telescopic end of the front second electric push rod 15 extends and drives the limiting frame 16 to move backward, the horizontal part of the front limiting frame 16 extrudes the limiting strip 801, the front limiting strip 801 drives the push plate 8 and the parts thereon to rotate clockwise (from left to right), and then the push plate 8 gradually changes from the horizontal state to the vertical state, and then the front first electric push rod 9 is started, the sliding frame 6 and the parts thereon move backward until the rear side of the front push plate 8 contacts the patient's body, then the front first electric push rod 9 is closed, and the front push plate 8 after rotation supports and limits the front part of the patient, thereby increasing the stability of the patient during turning over and reducing the probability of secondary injury of the patient during turning over. Figure 1

[0050] ​​When the front push plate 8 moves backward, the rear first electric push rod 9 is activated, causing the rear push plate 8 to move its upper parts forward, and repeating the above process to extend into the lower part of the patient's body. When the rear fixing plate 22 contacts the patient's body, the rear fixing plate 22 moves its upper parts upward along the patient's body to adapt to the characteristics of the patient's body until the baffle 24 contacts the patient's body. Then, the rear baffle 24 drives the fixing plate 22 to rotate clockwise. Figure 1 (Viewed from left to right) The fixing plate 22 cooperates with the adjacent push plate 8 to clamp the patient's body, increasing the stability during the patient's turning process. Until the baffle 24 contacts the adjacent positioning plate 19, the baffle 24 and its parts stop moving. At this time, the first electric push rod 9 on the rear side closes.

[0051] After the first electric push rod 9 is closed, the rear motor 4 starts, causing the lifting frame 3 to move its parts upward to flip the patient. At this time, the first electric push rod 9 starts again and repeats the above process, causing the rear push plate 8 to move with the patient's body as it flips. During this process, the second electric push rod 15 starts, causing the telescopic end of the second electric push rod 15 to drive the limiting frame 16 to gradually move backward, so that the pressure of the limiting frame 16 on the rear limiting strip 801 gradually decreases. As a result, the rear push plate 8 gradually rotates clockwise under the pressure of the patient's body, so that the rear push plate 8 is always in contact with the lower side of the patient, adapting to the changes in the body angle during the patient's rotation.

[0052] During the patient's turning process, the patient's body presses against the front push plate 8, which rotates clockwise and causes the adjusting rod 25 to move along the guide groove of the positioning plate 19. The adjusting rod 25 compresses the second spring 27 by pushing the limiting block 26, increasing the resistance to the rotation of the push plate 8, thereby increasing the resistance during the patient's turning process and ensuring the stability of the patient's turning process. After the second spring 27 can no longer be compressed, the front push plate 8 and its parts stop moving, and the staff turns off the electrical components, and the patient's turning is completed.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
