Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically a nursing device with a turning function. Background Technology

[0002] Chinese Patent Publication No. CN107242949A discloses a nursing device for critically ill elderly patients, including a bed frame, mattress, bed sheet and pillow, bed back, left turning support, right turning support, lower body lifting support, upper body lifting support, casters, drive wheels, support frame, drive transmission wheel, drive motor, motor transmission wheel, transmission belt, bed legs, lower body lifting hydraulic device, upper body lifting hydraulic device, central support wheel, drive device frame, etc. The upper body lifting support and lower body lifting support are provided at the front and rear ends of the upper part of the bed frame, and the left turning support and right turning support are provided on both sides of the middle of the upper part of the bed frame. The drive device frame is provided at the front and rear of the bottom of the bed frame. This nursing device for critically ill elderly patients not only enables patients to get up and turn over, but also enables patients to move their bodies. At the same time, patients can move around indoors using this nursing device, which helps patients with self-care and assists in activity therapy. However, the device has a flaw in its use. The upper body lifting support is hinged to the bed frame. When the upper body lifting support is used to lift the patient's upper body, the upper body lifting support and the bed frame rotate. Since everyone's height is different, different parts of the body will be in contact with the bed frame at different positions. When lifting the patient's upper body, the patient's buttocks will form a support point against the horizontal bed frame. If they are not in contact, the patient will slide along the bed frame, and the pillow will also slide or even fall off the bed frame. This makes it impossible to support the patient's head and neck at all times, and it is not convenient to use. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art; to this end, the present invention proposes a nursing device with a turning function.

[0004] The objective of this invention can be achieved through the following technical solutions: A nursing device with a turning function includes a support frame and a bed board, wherein the bed board is composed of a first plate and a second plate, and the first plate and the second plate are rotatably connected.

[0005] An adjustment mechanism is mounted on the first plate. Upon receiving an adjustment signal from the controller, the adjustment mechanism adjusts the headrest position. The adjustment signal is determined through adjustment analysis by the controller. Specifically, the adjustment analysis method is as follows: The weight recognition module uses gravity sensors on the bed board to obtain the weight on the bed board and generate weight information; An angle recognition module is used to acquire the angle change of the first plate and generate angle information, and generate a start / stop signal for controlling the electromagnet by analyzing the information. The acquisition and analysis module is used to analyze the acquired weight and angle information. By comparing the weight information with the basic weight of the bed board and combining it with the angle information, the module generates a second start / stop signal to control the infrared sensor. The infrared sensor on the connecting rod captures the real-time position of the patient's head on the first board and generates position information. Then, the weight information, start / stop signal one, start / stop signal two, and position information are transmitted to the control information output module. The control information output module is used to feed back the acquired weight information, start / stop signal one, start / stop signal two and position information to the first cylinder, and use the first cylinder to control the headrest to move under the patient's head.

[0006] A turning mechanism is installed between the support frame and the bed board, and the turning mechanism is used to adjust the angle of the first board.

[0007] As a further aspect of the present invention: the adjustment mechanism includes a first cylinder fixedly connected to the first plate, a connecting frame fixedly connected to the output end of the first cylinder, a connecting rod connected to the connecting frame via a connecting assembly, and a fixing clip for holding the headrest fixedly connected to the connecting rod.

[0008] As a further aspect of the present invention: the connecting assembly includes a support plate fixedly connected to the connecting frame, and a connecting block fixedly connected to the bottom of the connecting rod, wherein the support plate is provided with an electromagnet that cooperates with the connecting block.

[0009] As a further aspect of the present invention: a through groove is provided on one side of the support plate, the top of the through groove cavity is open, and the through groove is composed of dovetail grooves and placement grooves that are interconnected.

[0010] As a further embodiment of the present invention: the connecting block and the dovetail groove are slidably connected, and the electromagnet is disposed in the placement groove.

[0011] As a further aspect of the present invention: the support plate is slidably connected to the first plate body, and the connecting rod is in contact with the support plate.

[0012] As a further embodiment of the present invention: the turning mechanism includes a first shaft mounted on a support frame, a second shaft mounted on a first plate, and a rotating frame rotatably connected to a second plate. A rotating body is rotatably connected to the first shaft, and a connecting shaft first and a connecting shaft second are fixedly connected to the rotating body respectively. A connecting arm is rotatably connected between the first connecting shaft and the second shaft, and a second cylinder is rotatably connected between the second shaft and the rotating frame.

[0013] As a further aspect of the present invention: two inclined blocks are fixedly connected to the first plate, and the second shaft is fixedly connected between the two inclined blocks; two connecting plates are fixedly connected to the support frame, and the first shaft is fixedly connected between the two connecting plates.

[0017] 2. This application utilizes the dovetail groove, connecting block, and electromagnet in combination. When the patient's upper body is supported, the electromagnet and connecting block attract each other, causing the headrest to move with the adjustment mechanism.

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0022] Please see Figures 1-5 As shown, this application provides a nursing device with a turning function, including a support frame 1 and a bed board 2. The bed board 2 is composed of a first plate 21 and a second plate 22, and the first plate 21 and the second plate 22 are rotatably connected. Adjustment mechanism 3 is disposed on the first plate 21. When the adjustment mechanism 3 receives an adjustment signal from the controller, it adjusts the position of the headrest 4. The adjustment signal is determined by the controller through adjustment analysis. The specific adjustment analysis method is as follows: The weight recognition module uses a gravity sensor on the bed board 2 to obtain the weight on the bed board 2 and generate weight information. The specific method for generating weight information is as follows: gravity sensors are installed on the first plate 21 and the second plate 22. The gravity sensors can be used to identify whether a patient is lying on the bed board 2 and generate weight information.

[0023] Angle recognition module, which is used to acquire the angle change of the first plate 21 and generate angle information, and generate start and stop signals for controlling electromagnet 333 by analysis; The specific method for generating start / stop signal 1 is as follows: when the first plate 21 rotates, the electromagnet 333 will work and generate start / stop signal 1, and the electromagnet 333 will be attracted and fixed together with the connecting block 332.

[0024] The acquisition and analysis module is used to analyze the acquired weight and angle information. By comparing the weight information with the basic weight of the bed board 2 and combining it with the angle information, the module generates a second start / stop signal to control the infrared sensor. The infrared sensor on the connecting rod 34 captures the real-time position of the patient's head on the first board 21 and generates position information. Then, the weight information, start / stop signal one, start / stop signal two and position information are transmitted to the control information output module. The specific method for generating start / stop signal two is as follows: when the gravity sensor detects that a patient is lying on the bed board 2 and the first board 21 rotates, the infrared sensor is in working condition and generates start / stop signal two.

[0025] The specific method for generating position information is as follows: when the first plate 21 rotates, the position of the patient's head on the first plate 21 will change, and the infrared sensor in working state will constantly identify the position of the patient's head and generate position information.

[0026] The control information output module is used to feed back the acquired weight information, start / stop signal one, start / stop signal two and position information to the first cylinder 31, and use the first cylinder 31 to control the headrest 4 to move under the patient's head. A turning mechanism 5 is installed between the support frame 1 and the bed board 2. The turning mechanism 5 is used to adjust the angle of the first board 21.

[0027] The adjustment mechanism 3 includes a first cylinder 31 fixedly connected to the first plate 21. The first cylinder 31 is electrically connected to an external power source and controlled by a control program. A connecting frame 32 is fixedly connected to the output end of the first cylinder 31. A connecting rod 34 is connected to the connecting frame 32 via a connecting assembly 33. A fixing clip 35 for holding the headrest 4 is fixedly connected to the connecting rod 34. When the first plate 21 rotates on the second plate 22, when supporting the patient's upper body, the patient's buttocks will form a support point against the horizontal bed frame. If they are not against the bed frame, the patient will slide along the bed frame. At the same time, the control system will intervene (when the gravity sensor can detect the patient's weight on the bed board 2, the infrared sensor will work when the first plate 21 rotates, and the electromagnet 333 will also work; when the gravity sensor cannot detect the patient's weight on the bed board 2, the infrared sensor will not work when the first plate 21 rotates). (While the infrared sensor detects the patient's head movement, the first cylinder 31 and the electromagnet 333 work simultaneously with the infrared sensor, which in turn moves the connecting frame 32, which in turn moves the support plate 331. The electromagnet 333 and the connecting block 332 are attracted to each other, so the connecting rod 34 moves synchronously with the support plate 331, which in turn moves the headrest 4 synchronously through the connecting rod 34 and the fixing clamp 35, thus ensuring that the headrest 4 always supports the patient's head and neck.)

[0028] The connecting assembly 33 includes a support plate 331 fixedly connected to the connecting frame 32, and a connecting block 332 fixedly connected to the bottom of the connecting rod 34. The support plate 331 is provided with an electromagnet 333 that works in conjunction with the connecting block 332. The electromagnet 333 is electrically connected to an external power source and is controlled by a control program.

[0029] Both the connecting rod 34 and the fixing clamp 35 are wrapped with sponge, and the connecting rod 34 is attached to the first plate 21. Example 2

[0030] Based on Example 1, see Figure 4 and Figure 5 As shown.

[0031] A through groove 6 is provided on one side of the support plate 331. The top of the groove 6 is open. The through groove 6 consists of a dovetail groove 61 and a placement groove 62 that are interconnected. When the first plate 21 is in a horizontal state, the electromagnet 333 is not in a working state. Therefore, the electromagnet 333 and the connecting block 332 are only in contact and not attracted together. When the patient needs to adjust the position of the headrest 4 (along the direction of the human body from head to toe), the headrest 4 can be moved directly. When the headrest 4 is moved, the connecting block 332 will slide in the dovetail groove 61. Through the cooperation of the connecting block 332 and the dovetail groove 61, the headrest 4 can be moved normally. At the same time, it is also beneficial for the first plate 21 to be fixed together with the electromagnet 333 when the angle is adjusted.

[0032] The connecting block 332 is slidably connected to the dovetail groove 61, and the electromagnet 333 is disposed in the placement groove 62.

[0033] The support plate 331 is slidably connected to the first plate 21, and the connecting rod 34 is attached to the support plate 331. Example 3

[0034] Based on Example 1, see Figure 2 , Figure 3 and Figure 6 As shown.

[0035] The turning mechanism 5 includes a first shaft 51 mounted on the support frame 1, a second shaft 52 mounted on the first plate 21, and a rotating frame 53 rotatably connected to the second plate 22. A rotating body 54 is rotatably connected to the first shaft 51. A first connecting shaft 55 and a second connecting shaft 56 are fixedly connected to the rotating body 54. A connecting arm 57 is rotatably connected between the first connecting shaft 55 and the second shaft 52. A second cylinder 58 is rotatably connected between the second shaft 52 and the rotating frame 53. The second cylinder 58 is electrically connected to an external power source and is controlled by a control program. When the patient needs to sit up while lying on the bed board 2, the second cylinder 58 is activated, and the output end of the second cylinder 58 retracts, causing the second cylinder 58 to rotate on the rotating frame 53. The rotating frame 53 rotates on the second plate 22, and the second cylinder 58 drives the rotating body 54 to rotate on the connecting plate 8 via the shaft 1 51. The rotating body 54 drives the connecting arm 57 to rotate via the connecting shaft 1 55, and thus drives the first plate 21 to rotate along the second plate 22 via the inclined block 7 and the shaft 2 52.

[0036] Two inclined blocks 7 are fixedly connected to the first plate 21. The second shaft 52 is fixedly connected between the two inclined blocks 7. Two connecting plates 8 are fixedly connected to the support frame 1. The first shaft 51 is fixedly connected between the two connecting plates 8.

[0037] The length of the second connecting shaft 56 is greater than the length of the first shaft 51, and the length of the first shaft 51 is greater than the length of the first connecting shaft 55. Example 4

[0038] Referring to Embodiments 1, 2, and 3, see Figures 1-6 As shown.

[0039] When the patient's upper body is supported, the control system identifies the position of the patient's head and activates the first cylinder 31 to move the headrest 4, so that the headrest 4 is always supporting the patient's head and neck.

[0040] The working principle of this invention is as follows: When the patient needs to sit up while lying on the bed board 2, the second cylinder 58 is activated, and the output end of the second cylinder 58 retracts, causing the second cylinder 58 to rotate on the rotating frame 53. The rotating frame 53 rotates on the second plate 22, and the second cylinder 58 drives the rotating body 54 to rotate on the connecting plate 8 via the shaft 1 51. The rotating body 54 drives the connecting arm 57 to rotate via the connecting shaft 1 55, and thus drives the first plate 21 to rotate along the second plate 22 via the inclined block 7 and the shaft 2 52. As the first plate 21 rotates on the second plate 22, supporting the patient's upper body, the patient's buttocks will form a support point against the horizontal bed frame. If they are not in contact, the patient will slide along the bed frame. Simultaneously, the control system will intervene (when the gravity sensor can detect the patient's weight on the bed plate 2, the infrared sensor will activate while the first plate 21 rotates, and the electromagnet 333 will also operate; when the gravity sensor cannot detect the patient's weight on the bed plate 2, the infrared sensor will not activate while the first plate 21 rotates). The first cylinder 31 and the electromagnet 333 work together with the infrared sensor, which in turn will move the connecting frame 32 and the support plate 331. The electromagnet 333 and the connecting block 332 are attracted to each other, so the connecting rod 34 moves synchronously with the support plate 331. In turn, the connecting rod 34 and the fixing clamp 35 will move the headrest 4 synchronously, thus ensuring that the headrest 4 always supports the patient's head and neck. When the first plate 21 is in a horizontal state, the electromagnet 333 is not in working state. Therefore, the electromagnet 333 and the connecting block 332 are only in contact and not attracted together. When the patient needs to adjust the position of the headrest 4 (along the direction of the human body from head to toe), the headrest 4 can be moved directly. When the headrest 4 is moved, the connecting block 332 will slide in the dovetail groove 61. Through the cooperation of the connecting block 332 and the dovetail groove 61, the headrest 4 can be moved normally, and it is also beneficial for the first plate 21 to be fixed together with the electromagnet 333 when the angle is adjusted.

[0041] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
