Description

Technical Field

[0001] The present invention relates to the technical field of nursing beds, in particular to a nursing bed adopting mechanical visual sensing and artificial intelligence control. Background Art

[0002] Totally disabled people mainly live in bed and require full-time care. They live with the disease for an average of more than eight years. In response to this new market demand, many companies at home and abroad have launched smart nursing bed products with their own characteristics.

[0003] Although these products are currently named as smart, they actually use traditional electromechanical control (such as PLC control) to control the bed to make a certain degree of deformation to provide assistance to the patient. It does not fundamentally solve the most important and prominent problem in the nursing process, that is, the problem of patients taking care of their own urination and defecation. Most of the solutions can be summarized into two routes: one is to open a hole in a fixed position on the bed, and add a toilet with a cleaning and drying function under the hole. When the patient urinates or defecates, the electric push rod removes the mattress of the hole in the bed to expose the toilet opening. After the patient urinates or defecates, the flushing and drying equipment attached to the toilet will flush and dry the patient. This type of technology has two defects. One is that the bed Most bedridden patients have lower limb disability and cannot move their bodies to face the toilet bowl by themselves. After defecation and urination, since the flushing equipment is fixed, bedridden patients cannot adjust their bodies like ordinary people, so it is impossible to ensure that the effective parts are flushed, let alone flushing cleanly. In actual use, without the assistance of caregivers, the mattress at the opening of the bed is often dirty and wet, and caregivers still need to manually scrub after defecation. Caregivers also need to clean and remove black water in time after defecation. Such patients still need nursing staff to participate in care and cleaning during defecation. Although such products have reduced the labor intensity of nursing to a certain extent, they are far from the concept of intelligent nursing. The second common technical route is to use wearable devices, which generally clamp the soft plastic briefs connected by pipelines in the patient's crotch. Such equipment is OK for short-term use, but the patient's feelings for long-term use can be imagined. For this reason, we propose a nursing bed that uses mechanical vision sensing and artificial intelligence control. Summary of the invention

[0034] A third stepper motor 8 is installed on the bed frame 1 and below the lifting platform 9. The output end of the third stepper motor 8 is connected to the lifting platform 9 through a driving shaft. The third stepper motor 8 can drive the lifting platform 9 to rise and fall.

[0035] Secondly, it also includes a fourth stepper motor 16 and a fifth stepper motor 17 installed on the bed frame 1. The fourth stepper motor 16 realizes the Y-axis positioning of the toilet seat 10 above the lifting platform 9 through the driving shaft, and the fifth stepper motor 17 drives the negative pressure toilet 7 to move in the X direction through the driving shaft.

[0036] Among them, see Figure 1 and Figure 2 As shown, a first electric push rod 14 is installed on the lower end surface of the first bed board 21 through a hinge seat, and the end of the first electric push rod 14 is installed on the manipulator 4. A first stepper motor 5 is installed on the bed frame 1 and below the first bed board 21. The output end of the first stepper motor 5 is connected to a guide rod through a driving shaft, and the guide rod is connected to the lower end surface of the first bed board 21. A second stepper motor 6 and a sixth stepper motor 18 are also installed below the first bed board 21. The second stepper motor 6 moves the first bed board 21 upward through the driving shaft, and the sixth stepper motor 18 is used to drive the manipulator 4 to move along the Y-axis. The first stepper motor 5 and the second stepper motor 6 cooperate to realize the tilt of the first bed board 21, and cooperate with the first electric push rod 14 to realize the change of the extended length of the manipulator 4.

[0037] See also Figure 1 and Figure 2 As shown, the visual monitoring component 11 includes a first visual sensor 111 and a second visual sensor 112, and an AI control model and a control program sensed by a mechanical visual sensor are established. The first visual sensor 111 is arranged at the first bed board 21, and the second visual sensor 112 is installed on the bed frame 1 and is directly opposite to the negative pressure toilet 7. The visual sensor is a device that can convert an optical image into an electronic signal. Its main function is to obtain image information of a target object, and to sense the intensity, color, and distribution of light through internal photosensitive elements (such as CCD-charge coupled device, CMOS-complementary metal oxide semiconductor). There are many tiny photosensitive units distributed on these photosensitive elements. When light shines on these units, corresponding charge or current changes will be generated, which will then be converted into digital signals, and finally form images that can be processed by computers or other devices.

[0038] See also Figure 5 As shown, the first adjustment assembly 12 includes a second electric push rod 121 and a first connecting rod 122. The second electric push rod 121 is installed on the bed frame 1 and is located below the second bed board 22. The first connecting rod 122 is connected between the output end of the second electric push rod 121 and the lower end surface of the second bed board 22.

[0039] See also Figure 4 As shown, the second adjustment assembly 15 includes a third electric push rod 151 and a second connecting rod 152. One end of the third electric push rod 151 is installed on the lifting platform 9 through a bracket, and the second connecting rod 152 is connected between the other end of the third electric push rod 151 and the third bed board 23.

[0040] Based on the above, the specific usage can be described as follows:

[0041] 1. The AI ​​model analyzes the patient's lying posture through the first visual sensor 111 to give the patient's armpit coordinate data. The control program controls the first stepper motor 5 and the second stepper motor 6 according to the coordinate data to realize the upward movement of the first bed board 21. After the manipulator 4 extends out of the space, the control program controls the sixth stepper motor 18 based on the coordinate data. After the sixth stepper motor 18 drives the manipulator 4 to make a Y-axis displacement into place, the first electric push rod 14 is pushed out to support and fix the patient's body.

[0042] 2. The third stepper motor 8 drives the lifting platform 9 to fall into place, and the second adjustment component 15 pulls the third bed board 23 to the rear. At the same time, the second visual sensor 112 scans the patient's buttocks and determines the coordinates through the AI ​​model. The control program controls the third stepper motor 8 to link the toilet seat 10 above the lifting platform 9 to perform Y-axis positioning according to the coordinate data, and moves the toilet seat 10 under the patient's buttocks and then rises, so that the patient sits accurately on the toilet seat 10. The control program controls the fifth stepper motor 17 to drive the negative pressure toilet 7 to move in the X direction and move it under the toilet seat 10, so that the patient can urinate and defecate.

[0043] 3. After the patient has defecated, the warm water flushing head on the toilet will be cleaned along with the toilet according to the coordinates before defecation. After cleaning, the second visual sensor 112 will scan the patient's buttocks and judge the cleanliness according to the AI ​​model. If it is clean, the heater on the lifting platform 9 will blow dry it and the bed will return to normal according to the program. If the AI ​​model determines that it is not flushed clean, the specific coordinates of the uncleaned area will be given according to the data of the second visual sensor 112 to control the movement of the fourth stepper motor 16 and the fifth stepper motor 17, driving the warm water flushing head on the negative pressure toilet 7 to accurately clean it, and blow dry it after it is determined to be clean. After that, the axis system returns to zero and the bed returns to its normal lying state.

[0044] Example 2: Please refer to Figure 1 and Figure 5 As shown, this embodiment is extended on the basis of embodiment 1: backrests 13 are provided at both ends of the upper end surface of the bed board body 2. When the patient leans back, the back will not feel sore due to lack of support for a long time, so that the body is in a more comfortable posture, reducing the pressure on the waist and back muscles, and the first visual sensor 111 is preferably installed on the backrest 13 corresponding to the first bed board 21.

[0045] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
