[0030] The embodiment of the present application provides a nursing rehabilitation chair, which is suitable for patients with Alzheimer's disease, cerebrovascular disease and other neuropsychiatric diseases, and is applied to nursing in a family, a medical institution or a nursing home. The rehabilitation chair can restrain the behavior of the patient, so that the patient cannot freely move away from the rehabilitation chair, and can realize functions such as alarm for incontinence, prevention of falling, remote voice call, AI intelligent conversation and music therapy, back and foot massage, etc. Meanwhile, the rehabilitation chair can also monitor the movement and behavior of the patient through a vibration sensor, and when the patient is in a state of frenzy, the patient's attention can be diverted through psychological treatment such as language and music based on artificial intelligence for timely intervention. The present application can greatly relieve the energy and psychological pressure of the caregiver, and at the same time, provide the patient with the greatest degree of comfort, and can divert the patient's attention through voice call or music therapy when the patient is in a state of frenzy or illness, and improve the patient's clinical symptoms.

[0031] The nursing rehabilitation chair disclosed in the present application does not have special restrictions on the specific form of the rehabilitation chair, and can adopt Figure 1 , 2 For an embodiment of the present application, Figure 3 For another embodiment, a flexible, easy-to-clean and detachable material is arranged at the chair back and the cushion part, in addition to the chair form shown in the figure, a sofa form can also be adopted, a large number of soft packages are arranged at the chair back, the headrest and the armrest, and the material arranged at the chair back and the cushion part needs to be easy to clean and detachable. In order to facilitate the description, the high back chair shown in Figures 1-3 is taken as an example for description.

[0032] Referring to Figure 1 , the anti-falling nursing rehabilitation chair of the present application comprises a chair surface 1, a chair back 2, a support body 3 and an armrest 4. A flexible cushion 11 is detachably arranged on the chair surface 1, and a back cushion 21 and a headrest 22 are detachably arranged on the chair back 2. A pair of armrests 4 are arranged on the left and right sides of the rehabilitation chair respectively.

[0033] Some sick people may want to escape from the care, and finally lost or refused to cooperate with the medical care such as injection, blood pressure measurement due to amnesia or behavioral cognitive bias. Therefore, the restraint strap 41 capable of fixing the small arm of the patient is arranged on each armrest 4. For some patients who are always agitated or often escape from the care, sometimes the arms of the patient need to be fixed through the restraint strap 41. The restraint strap 41 can be made of various forms, such as magic tape or woven belt, and can be fixed at both ends by means of buttons, buckles, Velcro, ties, pins, zippers or other known fasteners to prevent the arms of the patient from moving relative to the armrest. In one embodiment, the length of the restraint strap along the extension direction of the armrest is greater than or equal to 10 cm, so that the arms can be better prevented from escaping from the restraint.

[0034] In one embodiment, the rehabilitation chair further comprises a restraint plate 42 capable of being opened or locked between a pair of armrests 4. One end of the restraint plate 42 is rotatably connected to the end of one armrest 4, and the other end is fixed to the end of the other armrest 4 through a locking device 43. Figure 3 In the embodiment shown, the restraint plate 43 can also be detachable relative to the armrest, and both ends thereof are fixed to the ends of the armrests 4 through the locking devices 43. The locking device can adopt a lock mechanism with a lock core and a key, and can also adopt a mechanical structure capable of preventing damage, many of which are known in the prior art and will not be described here.

[0035] In one embodiment, the restraint plate 42 can also be adjusted forward and backward along the armrest direction to adapt to people of different weights, thereby preventing the person from escaping from the rehabilitation chair.

[0036] Most sick old people will have decreased spatial recognition ability and decreased motor coordination ability as the disease progresses, and are prone to fall when standing or walking, causing accidental injury. Therefore, the rehabilitation chair also adopts a design to prevent the rehabilitation chair from falling. Specifically, the rehabilitation chair has a support body 3 below the seat surface 1, and the center of gravity of the rehabilitation chair is located below the seat surface 1, and the support body 3 is designed to prevent the rehabilitation chair from falling in the forward, rear, left and right directions. The conventional chair can only prevent the chair from falling forward or backward, and cannot prevent the chair from falling left and right, so the present application provides various structures that can prevent the chair from falling in four directions.

[0037] In Figure 1 , 2In the shown embodiment, the seat surface 1 is supported and fixed by four support legs 31, and a counterweight base 33 is arranged between the support legs 31 and the lower part of the rehabilitation chair, in which a steel plate or cement filling can be placed to increase the weight, and each support leg 31 is fixedly connected with the counterweight base 33. The bottom surface of the counterweight base 33 directly contacts the ground, which on one hand increases the friction to prevent falling, and on the other hand can lower the gravity center of the rehabilitation chair, so that the gravity center of the rehabilitation chair is lower than or equal to one third of the overall height of the rehabilitation chair.

[0038] In Figure 3 In the shown embodiment, another structure for preventing falling is adopted. As shown, the support body 3 includes a bottom plate 32 directly contacting the ground and a plurality of support legs 31 fixedly installed above the bottom plate 32. Since the bottom plate directly forms a surface contact with the ground and the area of the bottom plate 32 is larger than that of the seat surface 1, the entire rehabilitation chair can be stably supported on the ground, and the bottom plate 32 can be made of a metal material with a large self-weight, so that the patient is not easy to fall whether he shakes in the seat or stands up from the seat. Generally, the projection edge of the bottom plate 32 on the horizontal plane exceeds the projection edge of the seat surface by 5-30 cm, which can form a good anti-falling support effect. To prevent tripping, the height of the bottom plate 32 should not be set too thick, and it is appropriate to be less than 2 cm. It should be noted that in alternative embodiments, the bottom plate can also be set to other appropriate sizes according to actual needs, as long as it can increase the friction area, increase the self-weight, and prevent falling, which does not limit the protection scope of the present application.

[0039] In addition to the above embodiments, the present application can also adopt various anti-falling structures, such as using a plurality of support bodies with thickened bottom ends to support the seat surface, and filling cement counterweight in the inside of each support leg. Alternatively, a connecting piece can also be arranged at the bottom of one or more support feet and fixedly installed on the ground by bolts or pins.

[0040] At the same time, in order to enable the caregiver to timely discover that the cared person has fallen, the rehabilitation chair is also provided with an inclination sensor 14, which can be arranged on the backrest 2 or the seat surface 1, or integrated in the incontinence detection circuit. The inclination sensor 14 can detect the inclination angle of the rehabilitation chair relative to the horizontal plane and feed back an inclination electric signal, and the control circuit can issue a falling alarm information based on the inclination electric signal.

[0041] In addition, due to the existence of cognitive impairment, delusion, irritability, mania, shouting and other emotional instability symptoms in some patients, such as hitting the seat, shaking the seat back and forth, shouting and trying to get out of the seat, etc., the caregiver needs to intervene in time to calm down or psychologically guide. Therefore, in one embodiment of the present application, a vibration sensor is further arranged on the rehabilitation chair, which can detect the vibration or acceleration change of the seat and feed back a vibration electric signal, and the control circuit can send out a first emotional alarm information based on the vibration electric signal fed back by the vibration sensor.

[0042] In another embodiment, a decibel detection sensor is further arranged on the rehabilitation chair, which can convert a sound signal into an electric signal, and the control circuit can judge the current emotional state of the patient based on the size and duration of the electric signal, and send out a second emotional alarm information when the sound size exceeds a threshold.

[0043] For the elderly with Alzheimer's disease, timely emotional soothing is very important and difficult in nursing work when the emotions fluctuate violently, especially some old people only have positive feedback and soothing effect on the language of specific relatives, and some old people will become stable after hearing specific music or audio. Therefore, in one embodiment of the present application, a speaker and a microphone are arranged on the rehabilitation chair, and a storage module storing therapeutic music and a communication module capable of remote communication are included in the control circuit.

[0044] In one embodiment, the control circuit automatically initiates a request for remote call and automatically connects the bound guardian's mobile terminal for call when sending out the first emotional alarm information or the second emotional alarm information, so as to make the guardian calm down the patient's emotions and divert the patient's attention.

[0045] In one embodiment, the control circuit automatically plays music to divert the patient's attention when sending out the first emotional alarm information or the second emotional alarm information, and the music can be selected as soothing pure music or five-tone therapeutic music.

[0046] In some medical institutions or health care institutions, some patients also need medical services such as infusion, in order to facilitate infusion, the rehabilitation chair further has a fixing sleeve 24, the fixing sleeve 24 is detachably mounted with a hanging water rod 25, and the top of the hanging water rod 25 has at least one hook. The fixing sleeve 24 can be arranged on the chair back 2 or below the support body 3.

[0047] In some embodiments, a massage mechanism (not shown in the figure) is further arranged on the rehabilitation chair, which can be arranged on the chair back 2 or on the ground in front of the support body 3 to massage the back or feet of the patient. In some embodiments, the massage can be automatically started to calm the mood by diverting the attention of the patient in the case of detecting mood alarm information.

[0048] The cushion 11 of the present application is generally made of soft, waterproof, odor-resistant, and easy-to-clean materials. The surface of the cushion can also be provided with a permanent anti-virus and antibacterial coating. The cushion 11 can be of an integral structure, or can adopt a structure as shown, including a surface material 111 and a filling material 112. The surface material 111 is made of waterproof material, and the filling material 112 is made of high-elasticity or supporting sponge material. The surface material of the cushion is made of one or more than two of silicone material, resin material, ultra-fine polyethylene fiber material, or high-elasticity gel polymer material. To improve the comfort of the cushion, the cushion can also be provided with a cladding material, which is breathable and moisture-permeable. It should be noted that in alternative embodiments, the material of the cushion can also be plastic material or fabric material, etc., which does not limit the scope of protection of the application. Figure 4

[0049] The rehabilitation chair is provided with an incontinence detection circuit capable of detecting urinary and fecal incontinence, and a control circuit for sending alarm information outside in response to the detection result of the incontinence detection circuit. The incontinence detection circuit generates an electrical signal according to the incontinence condition information collected by the sensor and sends the electrical signal to the control circuit.

[0050] The incontinence detection circuit includes a first sensor mainly for detecting whether urinary incontinence occurs and a second sensor for detecting whether fecal incontinence occurs. The first sensor is placed on the cushion and is electrically connected to one or more detection probes. It can judge whether urinary incontinence occurs by detecting the humidity, temperature, or presence of conductive liquid in the environment, while the second sensor can judge whether fecal incontinence occurs by detecting the odor in the environment.

[0051] ​In one embodiment, the first sensor is a humidity sensor, a temperature sensor or a conductivity detection sensor, and the second sensor is an odor sensor. The humidity sensor, the temperature sensor or the conductivity detection sensor can use a chip known in the art. After incontinence, the humidity of the local part of the seat cushion will change, so that the change of the current detected by the humidity sensor can easily determine whether the incontinence of urination occurs. Similarly, after incontinence, the seat cushion surface is in contact with the conductive liquid, and the incontinence of urination can also be directly determined by the conductivity detection sensor. The body surface temperature of the human body is generally lower than the temperature of the body fluid, and the temperature of the urine of the human body is generally close to the temperature of the inside of the human body, and the temperature of the urine is generally between 37°C and 37.5°C, so when the first sensor is a temperature sensor, if the temperature detected is higher than 37 degrees, it can be judged that the incontinence of urination occurs. Of course, in some embodiments, in order to improve the accuracy of detection and prevent false alarms, a plurality of sensors can also be used for detection at the same time, and an alarm is given after comprehensive judgment.

[0052] In one embodiment, the detection probe 12 can be arranged in the seat cushion together with the first sensor, and the circuit part is separated from water by waterproof structure design, while the detection probe can be wet with water. The detection probe can be made of FPC flexible flat cable, which can be bent and conductive. In other embodiments, the first sensor can also be fixedly installed on the armrest, the back of the chair, the seat or the support body, and the detection probe can be movably placed on the seat cushion. Preferably, the detection probe has a certain flexibility and can be bent, such as being integrated on a soft film (such as FPC flexible circuit board). In this way, before each ride, the detection probe can be placed on the seat cushion and connected with the first sensor through a plug-in connector, and when the seat cushion is cleaned, the surface of the probe can be wiped and cleaned, and the seat cushion can be washed with water.

[0053] In one embodiment, the second sensor uses an odor sensor. Human feces contains skatole, amine gas, indole, hydrogen carbon and other substances, and thus emits a unique odor of feces. Urine also has some special components and presents a unique odor. Therefore, by detecting the odor of the seat cushion area, it can be determined whether there is a possibility of defecation and / or urination. The second sensor can convert the collected odor into an electrical signal and feed it back to the control circuit, and the control circuit can determine whether there is fecal incontinence according to the preset detection standard threshold.

[0054] In one embodiment, the first sensor and the second sensor are located on the surface of the seat cushion. It should be noted that in alternative embodiments, the first sensor and the second sensor can also be embedded in the seat cushion, or the first sensor and the second sensor can be arranged on the seat or the back of the chair, and only the detection probe is movably placed on the seat cushion.

[0055] The communication between the incontinence detection circuit and the control circuit can be realized by wired connection or wireless transmission.
