Description

Technical Field

[0001] The present invention relates to the field of electronic body temperature measurement, and particularly to a passive thermometer based on NFC. Background Art

[0002] Common electronic thermometers on the market at present mainly consist of a temperature sensing probe, a display screen, buttons, a battery, etc.; their temperature measurement principle is to use a temperature sensor to output an electrical signal, directly output a digital signal or convert the current signal into a digital signal that can be recognized by the internally integrated circuit, and then display the temperature in digital form through a display, such as a liquid crystal, a digital tube, an LED matrix, etc.

[0003] This kind of electronic thermometer is convenient for reading, but the built-in battery may have an adverse impact on the environment; during the measurement process, the temperature sensing probe must reach thermal equilibrium with the measurement part, and this process takes 2 - 5 minutes, so the measurement time is relatively long; the structure is relatively complex, it is difficult to be thinner and lighter or the cost is relatively high. In addition, some infrared measurement thermometers have also appeared on the traditional market at present. This kind of thermometer measures temperature by using the infrared principle and performs non-contact temperature measurement operations. Although this kind of thermometer can measure body temperature quickly, its accuracy is relatively low, the measured value deviation is relatively large, and it is easily affected by external air temperature and environmental factors. In addition, electronic thermometers also have defects such as large energy consumption, complex structure, poor moisture-proof and waterproof performance, and being easily affected by external working conditions. These defects reduce the accuracy of temperature measurement operations and affect the overall temperature measurement efficiency.

[0004] In summary, the present invention provides a passive thermometer based on NFC with a simple structure, convenient operation, small volume, high accuracy, non-contact temperature measurement, while ensuring the accuracy of the temperature measurement result, strong stability during overall use, energy saving, reduced battery loss, thin and light body, high measurement efficiency, and fast measurement speed, and has a broad market prospect. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a passive thermometer based on NFC with a simple structure, convenient operation, small volume, high accuracy, non-contact temperature measurement, while ensuring the accuracy of the temperature measurement result, strong stability during overall use, energy saving, reduced battery loss, thin and light body, high measurement efficiency, and fast measurement speed, so as to overcome the defects in the prior art.

[0006] The technical solution of the present invention is implemented as follows: A passive thermometer based on NFC includes a body temperature sensor and a data collector. The body temperature sensor includes an NFC reading coil, and the NFC reading coil is electrically connected to a temperature sensing chip probe through a flexible wire. The data collector includes an NFC induction coil that cooperates with the NFC reading coil. The NFC induction coil is connected to a controller through a signal acquisition module. The controller is connected to a networking transceiver module, and the networking transceiver module is connected to a remote receiving and storing module through a wireless connection. The NFC induction coil is installed in an induction housing, and a handheld body is provided at the bottom of the induction housing. The signal acquisition module, the controller, and the networking transceiver module are installed in the handheld body, and a first battery pack electrically connected to the controller is installed in the handheld body.

[0007] Further, a flexible bag is provided outside the NFC reading coil, the flexible wire, and the temperature sensing chip probe. The flexible bag is a double-layer sealed bag structure. One end of the flexible bag is a square structure, the middle part is a long strip structure, and the other end is a circular structure.

[0008] Further, a patch box is provided outside the NFC reading coil, the flexible wire, and the temperature sensing chip probe. There is a patch mounting groove on the handheld body that cooperates with the patch box. A glass cover is provided at the center of the back of the patch box, and the temperature sensing chip probe is attached to the inner side of the glass cover.

[0009] Further, an energy-saving digital display screen is provided on the outer side of the induction housing. The energy-saving digital display screen is connected to the controller through a digital display processing module.

[0010] Further, an interface for charging the first battery pack is provided at the bottom of the handheld body, and a power switch connected to the first battery pack and the controller is provided on one side of the handheld body.

[0011] Further, a first replaceable flexible adhesive layer is provided on the back of the flexible bag.

[0012] Further, a second replaceable flexible adhesive layer is provided on the outer circumference of the glass cover. The patch box is a square sheet structure, and a pulling block is provided at the front edge position of the patch box.

[0013] Further, a partition is provided inside the patch box. The NFC reading coil is arranged on one side of the partition, the temperature sensing chip probe is arranged on the other side of the partition, and the middle part of the flexible wire is arranged between one end of the partition and the inner wall of the patch box.

[0014] The present invention has the following positive effects: The NFC reading coil, flexible wire, and temperature-sensing chip probe of the present invention are wrapped in two different ways on the outside. The first way is to use a flexible bag for wrapping, which can be made of flexible materials, pasted on the patient's body, and can be flexibly creased according to the deformation of the pasting part. It can maintain adhesion to the outer layer of the patient's skin within a certain range of use and be used for temperature measurement for a long time. At the same time, the present invention provides a way to wrap the NFC reading coil, flexible wire, and temperature-sensing chip probe with a patch box. In this way, the patch box can be used in combination with the patch mounting groove on the handheld body. When not performing body temperature measurement, the patch box is installed in the patch mounting groove. When temperature measurement needs to be carried out, it is taken out and pasted on the skin surface for non-contact temperature measurement operation. No matter which of the above methods is adopted, the body temperature sensor itself is not equipped with a power supply, but uses the NFC method for temperature measurement operation. The overall body temperature sensor does not contain a battery, which can reduce battery consumption and reduce the harm of waste batteries to the environment. Since the body temperature sensor itself does not involve complex structures such as batteries and displays, it can be made very thin and light. When the body temperature needs to be measured, the data collector is brought close to it, and the body temperature data can be instantly collected without waiting. The body temperature sensor is pasted on the patient's body and is always in a thermal equilibrium state with the measurement part, so the collected body temperature data is more accurate and faster.

[0029] Embodiment 1: As Figure 1 , 2 , 3, 4, and 5 show, a passive thermometer based on NFC includes a body temperature sensor and a data collector. The body temperature sensor includes an NFC reading coil 2, and the NFC reading coil 2 is electrically connected to a temperature sensing chip probe 4 through a flexible wire 3. The data collector includes an NFC induction coil 10 that cooperates with the NFC reading coil 2. The NFC induction coil 10 is connected to a controller 13 through a signal acquisition module 12.

When temperature measurement needs to be performed, hold the handheld body 6 and bring the induction housing 8 close to the position of the NFC reading coil 2. After the power switch 7 is turned on, when the NFC induction coil 10 approaches the NFC reading coil 2 in a non-contact manner, the NFC reading coil 2 receives the electromagnetic signal emitted by the data collector, converts it into an electrical signal, drives the temperature-sensing chip probe 4 to collect the human body temperature, and then transmits the temperature signal to the temperature data through the NFC reading coil 2 and the NFC induction coil 10 for processing by the signal acquisition module 12. Finally, after processing, it is transmitted to the controller 13 and the reading is displayed on the energy-saving digital display screen 9. At the same time, it can also be transmitted to the HIS system of the hospital through the network transceiver module 14 for docking to achieve rapid measurement, collection, transmission, and management of the patient's body temperature.

[0032] Embodiment 2: As Figure 4 , 5 , 6, 7, and 8 show, a passive thermometer based on NFC includes a body temperature sensor and a data collector. The body temperature sensor includes an NFC reading coil 2, and the NFC reading coil 2 is electrically connected to a temperature-sensing chip probe 4 through a flexible wire 3.

[0034] During the operation of this embodiment, the patch box 17 is a hard structure that can be reused after disinfection and is made of plastic in this embodiment. Also, when in use, the second replaceable flexible adhesive layer 20 is in a replaceable mode. When it is necessary to attach the patch box 17 to the skin position, it is pasted on the back of the patch box 17 through the disposable replaceable second replaceable flexible adhesive layer 20 for use. The glass cover 19 is a circular structure, and the second replaceable flexible adhesive layer 20 is a ring-shaped adhesive layer structure. When in use, the glass cover 19 can conduct heat quickly and reach a rapid thermal equilibrium with the human body temperature.

[0035] During the operation of this embodiment, hold the handheld body 6 and bring the induction housing 8 close to the position of the NFC reading coil 2. After the power switch 7 is turned on, when the NFC induction coil 10 approaches the NFC reading coil 2 in a non-contact manner, the NFC reading coil 2 receives the electromagnetic signal emitted by the data collector, converts it into an electrical signal, drives the temperature sensing chip probe 4 to collect the human body temperature, and then transmits the temperature signal to the temperature data through the NFC reading coil 2 and the NFC induction coil 10 for processing by the signal acquisition module 12. Finally, it is processed and transmitted to the controller 13 and displayed on the energy-saving digital display screen 9. At the same time, it can also be transmitted to the HIS system of the hospital through the network transceiver module 14 for docking, realizing the rapid measurement, collection, transmission, and management of the patient's body temperature.

[0036] Embodiment 3: As Figure 9 、 10As shown in FIGS. 10 and 11, when the present invention is in operation, it includes a body temperature sensor and a data collector. The data collector includes an induction housing 8. A wireless receiving module 27 is installed inside the induction housing 8. A handheld body 6 is provided at the bottom of the induction housing 8. A controller 13 electrically connected to the wireless receiving module 27 is installed inside the handheld body 6. The controller 13 is connected to a networking transceiver module 14. The networking transceiver module 14 is connected to a remote receiving and storage module by wireless connection. A first battery pack 15 electrically connected to the controller 13 is installed inside the handheld body 6. The body temperature sensor includes a patch box 17. A wireless transmitting module 24 matching the wireless receiving module 27 is installed inside the patch box 17. The wireless transmitting module 24 is connected to a temperature sensing processor 23. The temperature sensing processor 23 is connected to a temperature sensing chip probe 4. A glass cover 19 is provided at the center of the back surface of the patch box 17. The temperature sensing chip probe 4 is attached to the inner side surface of the glass cover 19. A lithium battery 25 connected to the temperature sensing processor 23 is installed inside the patch box 17. A partition 21 is provided inside the patch box 17.

[0037] In this embodiment, the patch box can be attached to the skin surface or fixed to the skin surface by using a fixing band. A temperature sensing chip probe is installed inside the patch box, which can perform timed temperature measurement operations within a preset time range. The temperature measurement data is processed by the temperature sensing processor and then sent to an external wireless receiving module through the wireless transmitting module. The wireless receiving module displays it on the energy-saving digital display screen, or the body temperature data can be obtained by accessing the controller through the networking transceiver module by a remote monitoring device. Overall, it does not require contact temperature measurement operations and can achieve remote monitoring.

[0038] When this embodiment is in operation, the similarities with Embodiment 1 and Embodiment 2 are that it also adopts the structural settings of the handheld body 6, the patch box 17, and the induction housing 8, and at the same time, it also sets up the controller 13, the networking transceiver module 14, and the first battery pack 15. The difference is that the induction temperature measurement method in this embodiment is different. It sets up a wireless receiving module 27 and a wireless transmitting module 24. The independent lithium battery 25 in the patch box 17 is used to provide an independent power supply for the temperature sensing processor 23 and drive the temperature sensing chip probe 4 to perform temperature measurement operations. The measured data is transmitted to the wireless receiving module 27 through the wireless transmitting module 24, stored in the controller 13, and can be displayed on the energy-saving digital display screen 9 for viewing at any time within the wireless transceiver range. The controller 13 can drive the temperature sensing processor 23 to perform temperature measurement operations through the wireless receiving module 27 and the wireless transmitting module 24, and observe the temperature measurement data of the energy-saving digital display screen 9 within the wireless transceiver range. At the same time, the remote control terminal can also drive the controller 13 to issue a temperature measurement command by connecting to the networking transceiver module 14, and observe the measured body temperature through the display port of the remote control terminal, which is convenient for the user to send remote temperature measurement commands and observe body temperature data outside the wireless transceiver range.

[0039] Different from Embodiment 1 and 2, this embodiment adopts the method of setting an independent lithium battery 25 in the patch box 17. During operation, its temperature measurement operation is either regular temperature measurement or driven temperature measurement after receiving a command. During the overall use process, the power consumption of the lithium battery 25 during driving is relatively low, and it is ensured that its power will not generate excessive heating. The lithium battery 25 can be rechargeable for power replenishment. When in use, it is fixed at the measurement position by means of sticking or a fixing band. And in this embodiment, the patch box 17 can also be used repeatedly after disinfection, or be fixed for long-term use by the user.
