Abstract
The utility model discloses an online electronic transfusion monitor. A master control chip which is composed of a single chip microcomputer is connected with a power supply. The single chip microcomputer is respectively connected with the following components: a display circuit which is used for displaying the number of drops of soup and the residual time of transfusion, an alarming circuit, a wireless transmission module, a communication circuit, an amplification comparing circuit and a resetting circuit. The amplification comparing circuit is connected with an infrared sensor which is equipped to two sides of a dropper and is composed of two parts of a transmission part and a receiving part. The wireless transmission module is connected with a soup monitoring wireless receiving host placed in a nursing office through a wired or wireless mode. The online electronic transfusion monitor can quickly and accurately display the dropping speed of the soup drops and the residual time of transfusion through a liquid crystal display. The medical care personnel can communicate with the patient through a prior-art calling system for adjusting to a most ideal dropping speed for the patient in time and greatly reducing working load of medical personnel. The blood backflow phenomenon caused by a fact that the transfusion needle is not drawn out in time after all the soup is transfused.
Description
Technical field
This utility model relates to a kind of medical device product, specifically a kind of networking electronic infusion monitor.
Background technology
Have only a simple velocity modulation regulating device during hospital's transfusion at present, a speed of once being regulated by the nurse before transfusion is not an optimal speed for different patients probably; What have may feel that a speed is too fast, and also the meeting that has feels too slow, often will be by regulating several times; Whether whether transfusion is finished also and can only often be removed to watch attentively liquid level in the transfusion medicine bottle by medical personnel or patient or its nurse personnel in addition, finish to judge transfusion; Can not in time remind medical personnel or patient when finishing soon in transfusion, also cause medical personnel will carry out several times observation; This has increased their work load undoubtedly; Especially more as patient, when work is busy, and can not take care of oneself or not have the patient that the special messenger keeps an eye on for some; In time do not find after also causing transfusion to finish possibly; Might cause " blood back " or make in the part air admission patient body.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of and can monitor infusion process automatically, and can in time notify medical personnel's networking electronic infusion monitor when the infusion bottle inner liquid medicine will be use up.
This utility model is achieved through the following technical solutions: the main control chip that is made of single-chip microcomputer is connected with power supply, single-chip microcomputer respectively be used to show that medicine drips number and display circuit, automatic alarm circuit, wireless transmitter module, telecommunication circuit, amplification comparison circuit, the reset circuit of transfusion remaining time is connected; Amplify comparison circuit and be installed on the dropper both sides and be connected by transmitting and receiving the infrared sensor that two parts constitute, described wireless transmitter module is by wired or wireless mode and place and nurse the medicinal liquid monitoring wireless reception main-machine communication of doing and be connected.
Described telecommunication circuit is connected with existing medical calling system.
Described single-chip microcomputer is the 89c2051 single-chip microcomputer.
Described display circuit is the LCD display circuit that has the LCD LCDs.
Described power supply is a dc source, and its voltage range is 2.7～5V, and the single-chip microcomputer of described main control chip is electrically connected with voltage detecting circuit.Described voltage detecting circuit can detect supply voltage in real time, if supply voltage drops to below the work allowed band, monitor quits work automatically, is beneficial to point out patient or medical personnel in time to handle.
Described reset circuit can detect supply voltage in real time, if supply voltage drops to below the work allowed band, monitor quits work automatically, is beneficial to point out patient or medical personnel in time to handle.
This utility model can show a medicine speed and transfusion fast and exactly remaining time by liquid crystal display screen, patient can grasp the transfusion situation at any time; Need not to change existing medical calling system interface, medical personnel can exchange with patient by the existing call system, grasp different patients' requirement at any time, in time are adjusted to optimal speed of patient, alleviate medical personnel's workload greatly; Whether in time close by automatic alarm circuit prompting patient or medical personnel simultaneously and drip a velocity modulation regulating device, can avoid medicinal liquid to be totally lost and then cause " blood back " phenomenon because of in time not dialling pin.This utility model volume is little, low cost, be easy to carry, economical and practical, simple, convenient reliable.
Description of drawings
Fig. 1 is the theory diagram of this utility model one embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
With reference to Fig. 1: the power supply 1 of present embodiment is that voltage range is the dc source of 2.7～5V, model is that the single-chip microcomputer 2 of AT89c2051 is connected with dc source 1, single-chip microcomputer 2 drips the LCD display circuit 3 of number and transfusion remaining time with being used to show medicine respectively, warning circuit 4, wireless transmitter module 5, telecommunication circuit 6, amplify comparison circuit 8, reset key 9, voltage detecting circuit 10 is electrically connected, it amplifies comparison circuit and is installed on the dropper both sides and is connected by transmitting and receiving the infrared sensor 7 that two parts constitute, wireless transmitter module 5 receives main frame 11 by wired or wireless mode and the medicinal liquid monitoring wireless that places nursing to do and communicates to connect, and telecommunication circuit 6 is connected with existing medical calling system.Its LCD display circuit has the LCD LCDs.
After the start, single-chip microcomputer carries out self check, after the every function of initialization, enter duty, when process was installed on the infrared sensor of dropper both sides under the infusing medicine drippage, infrared sensor produced small voltage change signal, and infrared sensor sends voltage change signal to the amplification comparison circuit, voltage change signal is shaped to square-wave signal through amplifying comparison circuit, and this square-wave signal is admitted to single-chip microcomputer; Enumerator in the single-chip microcomputer is started working simultaneously, enumerator calculates fast when a prodrug speed, and it is fast to show that by the LCD LCDs medicine drips, unison counter drips the remaining time of infusing that how much calculates of speed and infusion bottle inner liquid medicine according to medicine, and the LCD LCDs of passing through the LCD display circuit shows the remaining time of infusing, in single-chip microcomputer under the effect of intervalometer interrupt mode, enumerator can recomputate a medicine and drip speed and infuse remaining time every 6 seconds, and by the demonstration of LCD liquid crystal display screen, if the LCD liquid crystal display screen shows " End ", and no longer show when medicine drips speed and infuses remaining time, illustrate that medicinal liquid has been totally lost or tube for transfusion stops up, at this moment, warning circuit starts automatically, and the buzzer of being located in the warning circuit sends prompt tone; Simultaneously, patient also can send the signalisation medical personnel to nurse station (nursing is done) by the existing medical calling system that links to each other with telecommunication circuit.
