In some embodiments, the detecting operation may further include the following operations performed before the processor 30 receives the physiological parameter signal from the signal processing circuit 20: controlling at least one group of radio frequency signal transceiving components 10 to emit electromagnetic waves with specific frequency towards the patient on the sickbed and receive reflected beams reflected by specific parts of the body of the patient on the sickbed; the control signal processing circuit 20 converts the reflected beams received by each group of rf signal transceiving components into corresponding physiological parameter signals.

Wherein the preset time is expected to be the time for the patient to return to the respective bed after receiving the prompting message, such as 20 seconds, 30 seconds, etc. Therefore, the measurement is started after the preset time for generating the prompt signal, and the physiological parameter signal of the patient can be effectively obtained.

In other embodiments, the contactless physiological sign monitoring device 100 may not include the prompting unit 70, and the aforementioned detection operation is performed when it is determined that the physiological characteristic measurement needs to be performed, instead of generating the prompting information.

In some embodiments, the processor is configured to control the prompting unit 70 to generate the prompting message when a triggering instruction of an authorized user is received through the communication unit 50.

In some embodiments, the processor 30 may also directly perform the aforementioned measurement operation when receiving the trigger instruction of the authorized user through the communication unit 50 without controlling the prompting unit 70 to generate the prompting message.

Wherein the target equipment comprises at least one of a mobile phone of a medical worker, a department-level workstation device and a hospital-level data center/hospital-level first aid center management device.

Wherein, in the present embodiment, each set of physiological parameter values includes at least one of a respiration rate and a heart rate. The electromagnetic wave of the specific frequency emitted by the rf transceiver component 10 may be a millimeter wave.

Referring to fig. 6 and 7 together, fig. 6 is a block diagram of a non-contact physiological monitoring device 100 'in another embodiment, and fig. 7 is a schematic view of a scenario in which the non-contact physiological monitoring device 100' in another embodiment is installed in a patient room. Therein, the difference with the contactless physiological signs monitoring device 100 'shown in fig. 1 is that in another embodiment, the contactless physiological signs monitoring device 100' comprises only one radio frequency signal transceiving component 10. Namely, the contactless physiological signs monitoring device 100' comprises a radio frequency signal transceiver module 10, a signal processing circuit 20 and a processor 30.

In this embodiment, the radio frequency signal transceiving module 10 is configured to transmit electromagnetic waves with a specific frequency toward all patients on the patient beds in the patient rooms, and receive reflected beams reflected from specific parts of the patient beds. It should be noted that, when there are a plurality of patient beds in a patient room, the radiation range of the electromagnetic wave emitted by the radio frequency signal transceiver module 10 should cover all patient beds.

The signal processing circuit 20 is configured to convert each reflected beam received by the set of rf signal transceiving components 10 into a corresponding physiological parameter signal. The processor 30 is configured to analyze each physiological parameter signal to obtain a set of physiological parameter values, determine patient identity information corresponding to each set of physiological parameter values according to an association relationship between a receiving angle at which the preset radio frequency signal transceiver assembly 10 receives the reflected beam and a hospital bed in a hospital room, and bind and output each set of physiological parameter values and the corresponding patient identity information.

That is, in other embodiments, an association relationship between the receiving angle of the radio frequency signal transceiver component 10 for receiving the reflected beam and the patient bed in the patient room is preset, and the patient identity information corresponding to each group of physiological parameter values is determined according to the association relationship between the receiving angle of the radio frequency signal transceiver component 10 for receiving the reflected beam and the patient bed in the patient room when the processor 30 receives the reflected beam by the radio frequency signal transceiver component 10.

Similar to the foregoing, specifically, the processor 30 determines, according to the association relationship between the receiving angle of the reflected beam received by the radio frequency signal transceiver component 10 and the patient beds in the patient rooms, the patient beds corresponding to each group of physiological parameter values, and obtains corresponding patient identity information according to the corresponding patient beds, where the patient identity information includes at least one of a bed number and a patient name. Determining the hospital bed also refers to determining the serial number of the hospital bed, wherein the serial number of the hospital bed can be a serial number including a hospital room number and a bed number, and each hospital bed has a unique serial number in the hospital.

The radio frequency signal transceiving module 10 also includes a radio frequency signal transmitting module 11 and a radio frequency signal receiving module 12, the signal processing circuit 20 includes an analog-to-digital converter 21, and the analog-to-digital converter 21 is coupled to the radio frequency signal receiving module 12 in the radio frequency signal transceiving module 10 and is configured to acquire reflected beams received by the radio frequency signal transceiving module 12 from various angles and convert the reflected beams received by the radio frequency signal receiving module 12 from various angles into corresponding physiological parameter signals, respectively.

The analog-to-digital converter 21 may receive the reflected beams received at each angle in a time-sharing manner and convert the received reflected beams into corresponding physiological parameter signals, respectively.

In some embodiments, the signal processing circuit 20 may also include the same number of analog-to-digital converters 21 as the number of patient beds, each analog-to-digital converter 21 is configured to correspond to a receiving angle, and convert the reflected beam received by the rf signal receiving component 12 from the corresponding receiving angle into a corresponding physiological parameter signal.

In some embodiments, the rf signal receiving assembly 12 may include a plurality of sensors for receiving reflected beams at corresponding angles.

That is, each sensor has a specific receiving angle. The processor 30 may determine the receiving angle according to the sensor receiving the reflected beam, and then determine the patient identity information corresponding to each group of physiological parameter values according to the association relationship between the receiving angle of the reflected beam received by the preset radio frequency signal transceiver assembly 10 and the patient bed in the patient room. Obviously, in other embodiments, the radio frequency signal transceiving module 10 can also implement multi-angle transmission and reception in other manners.

As shown in fig. 7, the radio frequency signal transceiver 10 is disposed on a ceiling or a wall of a patient room, and the radio frequency signal transceiver 10 can emit electromagnetic waves of a specific frequency toward a plurality of patient beds at a plurality of angles and receive reflected beams. Therefore, the detection of patients on a plurality of sickbeds can be realized through one radio frequency signal transceiving component 10.

As shown in fig. 7, the rf signal transceiver module 10 has a transmitting and receiving surface that is an arc surface, a curvature center of the arc surface is located at a side away from the patient's bed, a plurality of sensors for receiving reflected beams may be arranged in an array on the transmitting and receiving surface F1 that is the arc surface, and each sensor corresponds to a different receiving angle. The radio frequency signal transmitting component 11 can transmit specific electromagnetic waves to various angles by means of scattering. Wherein, the inductor can be an electromagnetic wave inductor.

The non-contact physiological sign monitoring device 100' shown in fig. 6 and 7 is different from the non-contact physiological sign monitoring device 100 described above only in that the number of the radio frequency signal transceiver assemblies 10 is only one, and the processor 30 determines patient identity information corresponding to each group of physiological parameter values according to the association relationship between the receiving angle of the radio frequency signal transceiver assemblies 10 receiving the reflected beam and the patient bed in the patient room.

And will not be described in detail herein.
