Description

Technical Field

[0001] The present application relates to the technical field of monitoring equipment, and in particular to an infusion alarm system. Background Art

[0002] When people are sick and hospitalized, infusion is a basic operation. During the infusion, patients need medical staff or family members to pay attention to the amount of medicine in the infusion bottle at any time. If the medicine in the infusion bottle is not monitored, once the medicine in the infusion bottle is exhausted, it will endanger the health of the patient, which will cause certain dangers to the patient. Monitoring the amount of medicine in the infusion bottle not only increases the workload of medical staff and family members, but also prevents the family members of the infusion patients from resting. At present, most infusion alarm systems have insufficient monitoring capabilities for multiple infusion units. Simply put, it is impossible to uniformly monitor the infusion bottles of multiple patients, which leads to reduced management and control efficiency of medical staff. In order to solve the defect that the traditional infusion alarm system reduces the management and control efficiency of medical staff, the present application proposes an infusion alarm system.

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] The present application provides an infusion alarm system.

[0020] like Figure 1As shown, in one embodiment of the present application, an infusion alarm system includes a detection device 100, a signal concentrator 200, a signal isolator 300, a centralized transmitter 400 and a display screen 500.

[0021] The detection device 100 is attached to the outer surface of an infusion container and includes a digital sensor 150 .

[0022] The signal concentrator 200 includes a digital sensor interface 210 and a level transponder 220 . The digital sensor interface 210 is electrically connected to the detection device 100 , and the digital sensor interface 210 is electrically connected to the level transponder 220 .

[0023] The signal isolator 300 is communicatively connected to the signal concentrator 200 .

[0024] The centralized transmitter 400 is in communication connection with the signal isolator 300 .

[0025] The display screen 500 is in communication connection with the centralized transmitter 400 .

[0026] Specifically, the detection device 100 and the signal concentrator 200 form the smallest subsystem, and the subsystem is placed at the bottom of the infusion container. By adjusting the angle of the laser emitter 140 of the detection device 100, the laser emitter 140 is irradiated on the digital sensor 150 of the detection device 100. The digital sensor 150 receives the light data and sends it to the signal concentrator 200 through I2C communication. Thereafter, the completion of the infusion is determined based on the voltage data of the digital sensor 150 received by the signal concentrator 200 reaching the voltage threshold. Then the signal isolator 300 converts the I2C communication data of the subsystem into 485 communication data, and the signal isolator 300 continuously sends the 485 communication data to the centralized transmitter 400, and then the centralized transmitter 400 will issue a red alarm indication on the display screen 500 and sound a buzzer at the same time, until the medical staff clicks to confirm and returns the confirmation information to the subsystem through 485 communication, at which time the subsystem releases the alarm state.

[0027] The digital sensor 150 of the detection device 100 may be a TSL25911 digital sensor.

[0028] The present application relates to an infusion alarm system. The detection device 100 provides a convenient method for early warning based on the principle that light diffracts on the surface of the liquid. The detection device 100 does not come into contact with the liquid when using this method for infusion early warning. It is lightweight, convenient, and low-cost. According to the ID number assignment of the digital sensor 150 of the 485 communication of the signal isolator 300, it can be indicated on the display screen 500 which specific infusion container has completed the infusion. A digital sensor 150 and an infusion container are in a one-to-one correspondence. When the centralized transmitter 400 receives the infusion completion alarm of the subsystem, the subsystem will stop sending the alarm information only when the subsystem confirms the return of the information, which improves the safety factor of the infusion alarm system.

[0029] like Figure 2 As shown, in one embodiment of the present application, the digital sensor interface 210 includes a signal interrupt receiving pin INT, a clock pin SCL1, a display data pin SDA1, a power pin VCC and a ground pin GND. The display data pin SDA1 and the clock pin SCL1 are both electrically connected to the level responder 220. The signal interrupt receiving pin INT is electrically connected to the detection device 100. The power pin VCC is externally connected to a first power supply. The ground pin GND is grounded.

[0030] This embodiment relates to a digital sensor interface 210. The display data pin SDA1 is used to receive a level signal for stopping the alarm. Only when the subsystem confirms the information is returned, the subsystem will stop sending the alarm information. This improves the safety factor of the infusion alarm system. The signal interrupt receiving pin INT is actually the start pin for starting the display screen 500 resolution format. When the signal interrupt receiving pin INT receives a high level signal, the clock pin SCL1 and the display data pin SDA1 will convert the high level signal of the power pin VCC into a data frame corresponding to the display screen 500 resolution format.

[0031] like Figure 2 As shown, in one embodiment of the present application, the level responder 220 includes a data communication pin SDA2 and a clock signal pin SCL2. The display data pin SDA1 is electrically connected to the data communication pin SDA2. The clock signal pin SCL2 is electrically connected to the clock pin SCL1.

[0032] Specifically, the level transponder 220 is preferably a level transponder of the STM8S003F3P6T model. In fact, the digital sensor interface 210 and the level transponder 220 implement data communication. The data transmission speed is faster, and the data flow efficiency of the entire system is higher. This improves the timeliness of monitoring the liquid level of the infusion bottle.

[0033] This embodiment relates to a level transponder 220. The TSL25911 model digital sensor sends the received signal to the STM8S003F3P6T model level transponder in the form of I2C communication, and the STM8S003F3P6T model level transponder judges the light intensity data transmitted by the TSL25911 model digital sensor, and then packs the judgment result and its own ID number into a data frame.

[0034] like Figure 2 As shown, in one embodiment of the present application, the level responder 220 further includes a first input terminal PC5 and a first output terminal PD6. The signal isolator 300 includes a second output terminal RE and a second input terminal DE. The first input terminal PC5 is electrically connected to the second output terminal RE. The first output terminal PC6 is electrically connected to the second input terminal DE.

[0035] Specifically, the first output terminal PC6 provides a reference voltage for the half-duplex communication output of the signal isolator 300 , and the first input terminal PC5 provides a reference voltage for the half-duplex communication output of the signal isolator 300 .

[0036] The present embodiment involves the communication between the level responder 220 and the signal isolator 300. Through the 485 communication isolation conversion of the signal isolator 300, the signal isolator 300 converts the I2C communication into the 485 communication mode and transmits it to the centralized transmitter 400. The use of the 485 communication mode can effectively increase the transmission distance and expand the scope of use of the product to a certain extent.

[0037] like Figure 2 As shown, in one embodiment of the present application, the level responder 220 further includes a first differential output terminal PD5 and a first differential input terminal PD6. The signal isolator 300 further includes a second differential output terminal RXD and a second differential input terminal TXD. The first differential output terminal PD5 is electrically connected to the second differential input terminal TXD. The first differential input terminal PD6 is electrically connected to the second differential output terminal RXD.

[0038] The present embodiment involves the communication between the level responder 220 and the signal isolator 300. The signal isolator 300 and the level responder 220 perform half-duplex communication. At the same time, in order to improve the stability of data transmission, the signal isolator 300 and the level responder 220 perform data transmission using differential signals, which has strong anti-interference performance.

[0039] like Figure 2As shown, in one embodiment of the present application, the signal isolator 300 further includes a half-duplex power input pin VISOIN, a half-duplex power output pin VISOOUT and a first capacitor 310. The half-duplex power input pin VISOIN and the half-duplex power output pin VISOOUT are electrically connected to point A. One end of the first capacitor 310 is electrically connected to point A. The other end of the first capacitor 310 is grounded.

[0040] This embodiment involves a signal isolator 300, and the signal isolator 300 is preferably a signal isolator of the ADM2587E model. The isolator is capable of duplex communication and half-duplex communication. This embodiment uses half-duplex communication, so it is necessary to electrically connect the half-duplex power input pin VISOIN and the half-duplex power output pin VISOOUT through a wire. It is worth mentioning that there is still noise interference when the half-duplex power input pin VISOIN and the half-duplex power output pin VISOOUT are electrically connected through a wire, and the first capacitor 310 needs to be grounded to filter out the noise.

[0041] like Figure 2 As shown, in one embodiment of the present application, the signal isolator 300 further includes a first enable pin A1, a second enable pin Y1, a third enable pin B1, a fourth enable pin Z1 and a first resistor 320. The first enable pin A1 and the second enable pin Y1 are electrically connected at point B. The third enable pin B1 and the fourth enable pin Z1 are electrically connected at point C. One end of the first resistor 320 is electrically connected to point B. The other end of the first resistor 320 is electrically connected to point C. The centralized transmitter 400 is electrically connected to points B and C.

[0042] Specifically, the centralized transmitter 400 preferably uses a transmitter of the STM32F103ZET6 model. Based on the signal isolation characteristics of the ADM2587E model, when the signal isolator 300 performs half-duplex communication, the first enable pin A1 and the second enable pin Y1 need to be electrically connected, and the third enable pin B1 and the fourth enable pin Z1 need to be electrically connected. It is worth mentioning that the first resistor 320 is set between point B and point C to consume serial noise.

[0043] This embodiment relates to the communication method of the centralized transmitter 400 and the signal isolator 300. When the centralized transmitter 400 receives the data frame based on 485 communication from the signal isolator 300, the data frame can be converted into an 8080 communication data frame to provide a video signal to the display screen 500. Of course, when the centralized transmitter 400 receives the data frame based on 485 communication from the signal isolator 300, the data frame can also be directly converted into a high or low level signal using 485 communication to drive the display composed of LED lights.

[0044] like Figure 2As shown, in one embodiment of the present application, the signal isolator 300 further includes a plurality of ground terminals, a first power terminal VCC1, a second power terminal VCC2 and a second power supply 330. Each of the ground terminals is grounded. The first power terminal VCC1 and the second power terminal VCC2 are both electrically connected to the second power supply 330.

[0045] Specifically, the multiple ground terminals of the level responder 220 are ground terminal GND1, ground terminal GND2, ground terminal GND3 and ground terminal GND4. These pins are used to ensure the normal operation of the signal isolator 300.

[0046] like Figure 3 As shown, in one embodiment of the present application, the detection device 100 includes an annular base frame 110, a first support arm 120 and a second support arm 130. The first support arm 120 and the second support arm 130 are both fixedly connected to the annular base frame 110. The first support arm 120 and the second support arm 130 are arranged on the same plumb plane.

[0047] This embodiment relates to a detection device 100. The annular base frame 110 can support an infusion bottle, and the first support arm 120 and the second support arm 130 can lift the bottom of the infusion bottle. In addition, the first support arm 120 and the second support arm 130 increase the contact area between the annular base frame 110 and the infusion bottle, thereby improving the support stability of the detection device 100 for the infusion bottle.

[0048] like Figure 3 As shown, in one embodiment of the present application, the detection device 100 further includes a laser emitter 140 and a digital sensor 150. The laser emitter 140 is disposed on the first support arm 120. The digital sensor 150 is disposed on the second support arm 130. The laser emitter 140 and the digital sensor 150 are disposed on the same horizontal plane. The digital sensor interface 210 is electrically connected to the digital sensor 150.

[0049] This embodiment relates to a detection device 100. Since the laser emitter 140 is arranged on the first support arm 120 and the digital sensor 150 is arranged on the second support arm 130, for a liquid medicine with low light transmittance, it is only necessary to keep the first support arm 120 and the second support arm 130 on the same plumb plane and to arrange the laser emitter 140 and the digital sensor 150 on the same horizontal plane. When there is a liquid medicine with low light transmittance between the laser emitter 140 and the digital sensor 150, the digital sensor 150 cannot receive the laser of the laser emitter 140, and when the liquid medicine drops below the page of the horizontal plane where the laser emitter 140 and the digital sensor 150 are located, the transparent infusion bottle enables the digital sensor 150 to receive the laser of the laser emitter 140, thereby realizing an alarm. For a liquid medicine with high light transmittance, the liquid medicine will refract the laser, and when the liquid medicine drops below the page of the horizontal plane where the laser emitter 140 and the digital sensor 150 are located, the transparent infusion bottle enables the digital sensor 150 to receive the laser of the laser emitter 140, thereby realizing an alarm.

[0050] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
