Optionally, based on the foregoing embodiment, as an optional implementation manner, the bluetooth gateway in fig. 2 may include: a Bluetooth antenna 201, a Bluetooth module 202, a processor 203, a WiFi antenna 204, a WiFi module 205, a memory 206, a signal power detector 207, and a timer 208; the processor is an operation and control center of the Bluetooth gateway and is respectively connected with the Bluetooth module and the WiFi module through serial ports, wherein the Bluetooth module is connected with the Bluetooth antenna, and the Bluetooth antenna is used for receiving Bluetooth signals broadcast by a plurality of sickbed terminals; the WiFi module is connected with the WiFi antenna and used for sending the received Bluetooth data from the plurality of sickbed terminals to the server through the WiFi antenna; the signal power detector is connected with the Bluetooth antenna to detect the signal intensity of the Bluetooth signals broadcasted by the plurality of sickbed terminals and received by the Bluetooth antenna; the timer is connected with the processor and used for timing.
Under the condition that the signal intensity of the Bluetooth signal received by the Bluetooth gateway is higher than a threshold value, the sickbed terminal sends a Bluetooth signal with first power; under the condition that the signal intensity of the Bluetooth signal received by the Bluetooth gateway is lower than a threshold value, the sickbed terminal sends a Bluetooth signal with second power; wherein the first power is lower than the second power; under the condition that the infusion parameters meet infusion early warning conditions, the Bluetooth gateway scans data broadcast by a plurality of sickbed terminals by adopting a first frequency and sends the received data to a server; under the condition that the liquid parameters do not accord with the transfusion early warning conditions, the Bluetooth gateway scans data broadcasted by the sickbed terminal by adopting a second frequency, and the received data is sent to the server; wherein the first frequency is greater than the second frequency.
It should be noted that, the signal power of the signals sent by the plurality of hospital bed terminals is controlled according to the strength of the bluetooth signals received by the bluetooth gateway, so that the signal power sent by the hospital bed terminals can be properly reduced under the condition of high received signal strength, the power consumption of the plurality of hospital bed terminals is further reduced, and power supply is saved. Optionally, in the case of low received signal strength, a signal power amplifier may be further disposed in the hospital bed terminal to amplify the transmitted bluetooth signal. In addition, the Bluetooth gateway scans Bluetooth signals of a plurality of sickbed terminals at a higher frequency under the condition that the infusion parameters accord with the infusion early warning conditions, so that the infusion parameters are sent to the server in time and then sent to each medical care terminal. Under the condition that the infusion parameters do not accord with the infusion pre-alarm condition, the Bluetooth signals of the plurality of sickbed terminals are scanned at a lower frequency, so that the power consumption of the Bluetooth gateway can be reduced.
When the Bluetooth gateway is powered on, firstly, automatically checking whether a network cable is connected, and if the network cable is not connected, starting WiFi; if no WiFi network name and key are configured by the gateway within a preset time period (for example, one minute), the gateway uses a default network name and key to connect WiFi; if a new WiFi network name and a new key need to be configured, an Android application EspTrach.apk can be used, namely, a mobile phone is firstly used for connecting the used WiFi network, then a password is input, and after confirmation, the mobile phone sends information to the gateway. The gateway can automatically start Bluetooth broadcast reception after being connected with the network, and forwards the received Bluetooth data to the server. As an optional implementation manner, an address of a server to which the gateway is to be connected may be set using an Android application serverp. The Bluetooth gateway can automatically connect a new server after updating the address of the server.
After the bluetooth gateway is connected to the corresponding server, the broadcast data sent by the hospital bed terminal communicating with the bluetooth gateway is received, and the received broadcast data, the identifier (for example, MAC address information) of the hospital bed terminal, the received signal strength, and the identifier of the gateway are forwarded to the server based on the MQTT (Message Queuing Telemetry Transport) protocol. The server establishes MQTT service and receives data sent by the sickbed terminal.
Optionally, the power supply manner of the bluetooth gateway 2 includes, but is not limited to, the following three types: (1) USB power supply; (2) active power over ethernet (i.e., POE powered); (3) the power supply is directly plugged into a commercial power socket.
As shown in fig. 1, after receiving the infusion parameters of at least one hospital bed forwarded by the bluetooth gateway 2, the server 3 sends the received infusion parameters to a corresponding medical care terminal, which may be a desktop terminal 4 in an office of a medical care worker or a mobile terminal 5 carried by the medical care worker, where the mobile terminal 5 may be a terminal device special for a hospital or a mobile device such as a general mobile phone. No matter which kind of medical care terminal, can show the infusion parameter of at least one sick bed on the interface.
It is easy to note that if the server 3 only displays the infusion parameters of each hospital bed on the medical care terminal, the medical care personnel still needs to pay attention to the infusion information of each hospital bed displayed on the interface in real time, so as to perform needle pulling or dressing change treatment before the infusion is about to be completed and the patient arrives at the corresponding hospital bed in time.
This improves the work efficiency to further reduce the burden. The server 3 can judge whether the infusion parameter of each sickbed accords with the infusion alarm condition after receiving the infusion parameter of each sickbed forwarded by the plurality of sickbed terminals 1 through the Bluetooth gateway 2, and outputs alarm prompt information to the corresponding medical care terminal under the condition that the infusion parameter of any sickbed accords with the infusion alarm condition so as to timely inform medical care personnel. Optionally, the form of the alarm prompt message includes, but is not limited to, any one of the following: and displaying, voice broadcasting, text prompting and the like on a display interface of the medical care terminal.
Because the infusion bottle and the infusion bag are made of different materials, and the volume of the infusion bottle or the infusion bag made of the same material has different specifications such as 100ml, 250ml, 500ml and the like, the weights of the infusion bottles or the infusion bags made of different materials and different specifications are greatly different, and correspondingly, the adopted infusion alarm conditions are also different. Therefore, as an optional embodiment, the server 3 may collect the initial weight of the infusion bottle or the infusion bag of each hospital bed through the hospital bed terminal 1, and determine the specification information of the infusion bottle or the infusion bag of each hospital bed and the corresponding infusion alarm condition according to the initial weight of the infusion bottle or the infusion bag of each hospital bed.
As an alternative embodiment, the system may further include: the alarm is used for outputting alarm prompt information under the condition that the infusion parameters accord with the infusion alarm conditions, wherein the infusion alarm conditions comprise at least one of the following conditions: the weight of the liquid medicine is within the preset weight range, and the remaining transfusion time of the liquid medicine is within the preset time range.
The weight of the infusion bottle or the infusion bag is increased instantly due to the fact that the infusion bottle or the infusion bag is pulled manually, and when a patient leaves a bed with the infusion bottle or the infusion bag, the detected weight of the infusion bottle or the infusion bag is possibly zero instantly, so that in order to improve the accuracy of alarming, first prompt information can be output through the hospital bed terminal 1 or the server 3 under the condition that the weight of the infusion bottle or the infusion bag of each hospital bed is lower than a first weight in a first time interval, and/or under the condition that the remaining infusion time of the infusion bottle or the infusion bag of each hospital bed is lower than the first time in the first time interval, wherein the first prompt information is used for prompting that the infusion bottle or the infusion bag of each hospital bed is in a state of being taken down by a user; the hospital bed terminal 1 or the server 3 outputs second prompt information under the condition that the weight of the infusion bottle or the infusion bag of each hospital bed is higher than the second weight in the second time interval and/or the remaining infusion time of the infusion bottle or the infusion bag of each hospital bed is higher than the second time in the second time interval, wherein the second prompt information is used for prompting that the infusion bottle or the infusion bag of each hospital bed is in a state of being pulled by a user; and the sickbed terminal 1 or the server 3 outputs alarm prompt information under the condition that the weight and/or the remaining transfusion time of the transfusion bottle or the transfusion bag of each sickbed meet the transfusion alarm condition in a third time interval.
It should be noted that the alarm may be installed in a hospital room, or may be installed in an office of a medical care provider, or may be carried around. The alarm can be a separate alarm, or can be arranged on other devices, for example, on the hospital bed terminal 1 (for example, the trumpet holes 1-8 on the hospital bed terminal 1 shown in fig. 3), or on a mobile terminal carried by the medical staff.
Optionally, as shown in fig. 3, the hospital bed terminal 1 provided in the embodiment of the present application may further include a call key 1-4, a setting key 1-5, a switch key 1-6, and a power key 1-7.

When the power key 1-7 of the sickbed terminal 1 is pressed, the sickbed terminal 1 enters a standby state, and if the power key 1-7 is pressed again, the sickbed terminal 1 is powered off. When an infusion bottle or an infusion bag is hung on the sickbed terminal 1, the sickbed terminal enters a working state, optionally, the current task can be finished by long-pressing of a power key 1-7, and the sickbed terminal returns to a standby state; if the infusion bottle or the infusion bag is taken down in the infusion process, the display screen 1-3 displays LEA, the patient enters a leaving state, the infusion bottle or the infusion bag is hung again, and the sickbed terminal 1 enters a working state again; after the transfusion is finished, the transfusion bottle or the transfusion bag is taken down, and the sickbed terminal returns to the standby state.
It should be noted that, when the hospital bed terminal 1 is in the working state, the data displayed by the display screens 1-3 includes, but is not limited to, the number of the bed, the working state of the infusion bottle or the infusion bag, the amount of the infused liquid medicine, the weight of the remaining liquid medicine, the remaining power of the hospital bed terminal, a mute icon, and the like.
The working mode of the sickbed terminal 1 can be switched by the switching key 1-6, and the sickbed terminal 1 can be switched between a glass bottle mode and a plastic bag by pressing the switching key 1-6 for a short time no matter the sickbed terminal is in a standby state or a working state. Alternatively, switching between silent and non-silent modes can also be performed by pressing the switch keys 1-6 for a long time. According to the different pressing time of the keys, different functions are realized, and the number of the used keys is reduced. When the sickbed terminal is in a mute state, a mute icon can be displayed on the interface on the display screen 1-3.
The setting keys 1-5 can be used for setting bed information, but not limited to setting bed information, when the hospital bed terminal 1 is in a standby state, long pressing of the setting keys 1-5 can enter the bed setting state, and after the bed number is set, long pressing of the setting keys 1-5 or detection of no key operation for a preset time (for example, 10 seconds), the currently set bed number is saved and the hospital bed terminal returns to the standby state. It is easy to note that when the hospital bed terminal with the built-in NFC reader approaches to the bed card (NFC tag), the bed number can be automatically read, and the bed number in the hospital bed terminal is reset for storage.
The call keys 1-4 may be used for a patient or an attendant to call a medical professional. When the patient or the attendant sees that the liquid medicine in the infusion bottle or the infusion bag is about to be infused, the corresponding medical attendant can be called through the calling key 1-4. When the hospital bed terminal is in a calling state, an interface of the calling state can be displayed on the display screen 1-3.
In addition, it should be noted that, because the remaining weight of the liquid medicine collected by the hospital bed terminal is used for judging the infusion condition of the infusion bottle or the infusion bag, the hospital bed terminal provided by the application can also support weighing calibration in order to prevent the problem that the hospital bed terminal is inaccurate in long-term use. Specifically, when the hospital bed terminal 1 is in the standby state, the switching key and the setting key are pressed, so that the hospital bed terminal 1 enters a weighing calibration state, an icon with a predetermined weight (for example, 1Kg) can be displayed on the display screen 1-3 to flash, after the calibration is started, a weight (for example, 1Kg) with the same weight is hung below the hospital bed terminal, after the icon stops flashing, the calibration is completed, the weight is taken down, and the hospital bed terminal returns to the standby state.
