Detailed Description

The present invention will be further described with respect to the following examples, but it is to be understood that these examples are for illustration purposes only and are not to be construed as limitations on the practice of the invention, and that like elements are designated by the same reference numerals.

Referring to fig. 1, 2 and 3, the turn-over monitoring device of the present invention is adapted to be mounted on a carrier 800 for a user 900 who is not mobile and cannot turn over himself/herself, and is capable of wirelessly communicating with an electronic device 700. The carrier 800 may be a bed or a chair, and is not limited to the above types, for convenience of description, in the following embodiments, the carrier 800 is provided in a bed type. The electronic device 700 may be a smart bracelet, a smart watch, smart glasses, a mobile phone, a tablet pc or a notebook pc, or a monitoring device of a medical station, or a cloud server, and the like, and is not limited to the above types.

The turn-over monitoring device comprises an RFID tag unit 3 arranged on the carrier 800 and against which the user 900 can lie, a reader 4 arranged around the carrier 800 and capable of driving the RFID tag unit 3, and a turn-over monitor 5 in signal connection with the reader 4 and capable of wireless communication with the electronic device 700.

The RFID tag unit 3 includes a plurality of RFID tags 31 arranged at intervals on the carrier 800. The RFID tag 31 is disposed on the carrier 800 in a position where the carrier 800 is leaned against and shielded by the user 900 when lying, for example, arranged in an area where the upper half of the user 900 is leaned against and shielded when lying.

In the present embodiment, nine RFID tags 31 arranged in a matrix arrangement are provided in the RFID tag unit 3, but the number and arrangement are not limited to the above. Each RFID tag 31 that is not shielded by the user 900 can be activated by the reader 4 to emit an identification signal.

In the embodiment, each RFID tag is passive, and needs to obtain the power source required for operation through the reading signal of the reader 4, but in other implementation aspects of the invention, a semi-active or active design may be adopted. In addition, since the human body is a substance with high dielectric constant, when the human body is tightly attached to the RFID tag 31, the resonant frequency of the antenna of the RFID tag 31 is also changed, and the reader 4 cannot drive the RFID tag to emit the identification signal.

The reader 4 can drive the RFID tag 31 to charge and send out the identification signal, and can receive the identification signal. Since the reader 4 is an existing component and numerous in type, it will not be described in detail.

The turn-over monitor 5 is signal-connected to the reader 4, and includes a recording unit 51, a wireless communication unit 52, a status setting unit 53, a turn-over program setting unit 54, a turn-over monitoring unit 55, a bed leaving warning unit 56, and a reminding unit 57.

The recording unit 51 records the reading time of each identification signal received by the reader 4. The wireless communication unit 52 can wirelessly communicate with the electronic device 700 for data transmission, and in the present embodiment, the wireless communication unit 52 wirelessly communicates with the electronic device 700 by bluetooth wireless communication technology, but in the implementation, common wireless communication technologies such as infrared, WiFi, ZigBee and the like may be adopted, and the types of the wireless communication technologies are not limited.

The state setting unit 53 is built-in with a plurality of turning postures representing postures of the user 900 lying on the carrier 800, and is operable to set a scheduled time for a specific time duration for each of the turning postures, and to set a posture judgment condition for each of the turning postures. Such as, but not limited to, lying on the back, lying on the left side, lying on the right side, or the like. Each posture determining condition can be used by the turn-over monitoring unit 55 to analyze and determine the turn-over posture of the user 900 currently.

In the present embodiment, each posture determination condition is a string of codes formed by arranging a plurality of "0" and/or "1" numbers in sequence, and each number in the posture determination condition corresponds to one RFID tag 31. Wherein "0" indicates that the corresponding RFID tag 31 is shielded and not read by the reader 4, and "1" indicates that the corresponding RFID tag 31 is exposed and read by the reader 4.

Taking fig. 2, 4, and 5 as an example, when the user 900 lies on the carrier 800 in a turning-over posture in which the user lies on his back, as shown in fig. 2, all the RFID tags 31 are shielded by the body of the user 900, so the corresponding posture determination condition is "0000000000000", when the user 900 lies in a turning-over posture in which the user lies on the right side, as shown in fig. 4, the corresponding posture determination condition is "000111111", and when the user 900 lies in a turning-over posture in which the user lies on the left side, as shown in fig. 5, the corresponding posture determination condition is "111111000".

In practice, the digital content of the posture determination condition is not limited to the above, and the digital content of the posture determination condition for each turning posture may be adjusted and set for users 900 with different body types, carriers 800 with different shapes, and different arrangement manners of the RFID tags 31. In addition, when the gesture determination condition is implemented, the content of the gesture determination condition is not limited to the code formed by the above-mentioned numbers, and may be presented in other forms capable of identifying that the RFID tag 31 is in the shielded state or the exposed state.

The turning program setting unit 54 is operable to set a plurality of turning postures in sequence, and to collect the scheduled time corresponding to each of the scheduled turning postures to establish a turning time schedule.

The turn-over monitoring unit 55 will drive the reader 4 to perform a reading identification operation on the RFID tag 31 at regular time, for example, once every 30 seconds or 1 minute, the turn-over monitoring unit 55 will determine that the RFID tag 31 corresponding to each identification signal read by the reader 4 is in an exposed state which is not shielded, and is determined as "1", and determine that the rest of the RFID tags 31 which are not read by the identification signal are in a shielded state which is shielded by the user 900, and are determined as "0". And the turn-over monitoring unit 55 will collect the current reading result of the RFID tag 31 by the reader 4 to establish a current posture data composed of sequentially arranged "0" and/or "1" numbers. Then, the turning posture corresponding to the current posture data is compared according to the posture judgment condition.

When the turning-over monitoring unit 55 is operated and started to execute a turning-over time schedule, the turning-over time schedule is timed, that is, the timing is timed according to the scheduled time of the turning-over postures, and when the timing reaches one of the turning-over postures, the reminding unit 57 is driven to send out a turning-over reminding message corresponding to the one of the turning-over postures. After a delay time, for example, 30 seconds, the user 900 is analyzed and determined to be in the current turning posture, and when the current turning posture is different from the one of the turning postures, the reminding unit 57 is driven to send out a warning message. When the currently compared turning-over posture is judged to be the same as the one turning-over posture, the turning-over monitoring unit 55 starts to time the scheduled time of the one turning-over posture in the turning-over time schedule, and ends the time counting at the scheduled time of the one turning-over posture, and when the time is counted to the next turning-over posture, drives the reminding unit 57 to send out the turning-over reminding message for the next turning-over posture, and continuously judges whether the current turning-over posture corresponds to the next turning-over posture.

When the reader 4 receives the identification signals sent by all the RFID tags 31 at the same time, the bed exit warning unit 56 determines that the user 900 leaves the vehicle 800, for example, falls off the vehicle 800 or leaves the vehicle 800 privately, and drives the reminding unit 57 to send a warning message indicating that the user 900 leaves the vehicle 800.

In this embodiment, when the body turning monitoring unit 55 activates the reminding unit 57 to send the body turning reminding message and the warning message, it synchronously sends a notification message to the electronic device 700 via the wireless communication unit 52, so that the electronic device 700 outputs the notification message to remind the user. However, in practice, it is not necessary to notify the electronic apparatus 700 through the wireless communication unit 52.

The turn-over reminding message and the warning message sent by the reminding unit 57 are message types capable of being perceived by the surrounding nursing staff, such as sound, voice, image, light and/or vibration.

Referring to fig. 1, 2 and 3, when the turn-over monitoring device of the present invention is used, according to the area of the carrier 800 that is to be covered when the user 900 lies in various turn-over postures, the RFID tags 31 are arranged on the carrier 800, so that when the user 900 changes to various turn-over postures, different RFID tags 31 are covered, and each covered RFID tag 31 cannot be read by the reader 4, that is, when the user 900 turns over to various turn-over postures, different RFID tags 31 are exposed and can be read by the reader 4.

Then, the caregiver can operate the state setting unit 53 to set the posture determination condition corresponding to each turning-over posture, based on the aforementioned positions of the RFID tags 31 set for the different turning-over postures. And further operates the turn-over procedure setting unit 54 to establish a turn-over time schedule according to the turn-over requirements of the user 900. Then, the wireless communication unit 52 is connected to the electronic device 700.

When the turn-over monitor 5 is activated to execute a turn-over time schedule, the turn-over monitoring unit 55 starts timing the turn-over time schedule, periodically drives the reader 4 to read the RFID tag 31, and recognizes the current turn-over posture according to the read result. When one of the turning-over postures scheduled by the timing to the turning-over time is reached, the reminding unit 57 is driven to send out a corresponding turning-over reminding message, so that the surrounding nursing staff can know that the user 900 needs to turn over. The turning-over monitoring unit 55 will drive the reminding unit 57 to send the warning message for reminding the surrounding care giver to assist the user 900 to turn over as soon as possible when determining that the current turning-over posture is different from the one of the turning-over postures of the turning-over time schedule after the delay time, and will send the control signal via the wireless communication unit 52 to drive the electronic device 700 to generate a message for reminding the relevant person, and when determining that the user 900 has been turned over to the turning-over posture corresponding to the turning-over time schedule, continue the timing of the turning-over time schedule until the last turning-over posture is over. In practice, the turn-over monitoring unit 55 may be driven to execute the turn-over time schedule in an infinite loop, or only in a certain number of loops.

When the turn-over monitoring unit 55 executes the turn-over time schedule, the bed exit warning unit 56 will drive the reminding unit 57 to send out a corresponding warning message when the reader 4 simultaneously reads the identification signals of all the RFID tags 31, and send out a corresponding warning message to the electronic device 700, so as to remind surrounding nursing staff and other related staff to immediately go to check whether the user 900 falls from the carrier 800.

It should be noted that, when the vehicle 800 is a chair type such as a wheelchair, the RFID tags 31 may be disposed at the chair back and the chair cushion where the limbs of the vehicle 800 abut, so that the RFID tags 31 can be exposed or shielded when the user 900 changes the sitting posture, but the implementation is not limited to the above-mentioned setting.

In the present embodiment, a plurality of RFID tags 31 are disposed on the carrier 800, the posture determination conditions of various turning postures are set by the state setting unit 53, the turning time schedule corresponding to the user 900 is planned and set by the turning program setting unit 54, and then a caregiver is reminded according to the turning time schedule, and whether the user 900 is turned correctly is monitored. In practice, however, the state setting unit 53 and the turning-over program setting unit 54 are not necessary, and the turning-over monitoring unit 55 may receive and analyze all the reading times recorded by the recording unit 51 for each RFID tag 31, and drive the reminding unit 57 to send out the turning-over reminding message when the time of one or more of the RFID tags 31 in the shielded state or the exposed state exceeds the corresponding scheduled time, so as to also remind the user of turning over.

In addition, in implementation, the RFID tag unit 3 may also be provided with only one RFID tag 31, and the turning-over monitoring unit 55 drives the reminding unit 57 to send a turning-over reminding message when determining that the time of the RFID tag 31 in the shielded state or the exposed state exceeds the corresponding scheduled time, so as to remind the user of turning over.

Referring to fig. 3 and 6, in the implementation of the turn-over monitoring device of the present invention, the RFID tag 31 may be disposed on the clothes 801 worn by the user 900 instead, for example, adhered and fixed to the back of the clothes 801 or the hip side of the trousers, and the turn-over posture of the user 900, such as lying on the back, lying on the left side or lying on the right side, can be detected by the RFID tag 31 being shielded when the user lies or sits on a carrier. That is, the RFID tag 31 can be disposed on one of the carrier and the clothes 801 worn by the user, or on both of them.

In summary, by the design of the RFID tag unit 3, the reader 4 and the turn-over monitor 5, it is able to more efficiently monitor whether the caregiver actually turns over the user 900 of the vehicle 800, and determine whether the turn-over posture is correct, and by the design of setting the schedule time for each turn-over posture and establishing the schedule of the turn-over time, it is convenient to respectively define specific turn-over plans for users 900 in various states, and it is able to assist the caregiver in taking care of the user 900 who needs to turn over frequently in a planned way, which is a very innovative design of turn-over monitoring device. Therefore, the object of the present invention can be achieved.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the contents of the specification should be included in the scope of the present invention.
