Abstract
A transfusion alarming device comprises a fixing device and a transfusion alarming circuit arranged on the fixing device. The transfusion alarming circuit adopts two detection electrodes to detect whether liquid exists in a transfusion pipe, controls a capacitive touch chip to transmit signals to a micro control unit when no liquid exists, and finally controls an alarming unit to send out alarm to remind medical workers to conduct treatment. The transfusion alarming device adopts the capacitive mode for detection and has the advantages of being high in anti-jamming capability, low in cost, free of drug contact and the like.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of transfusion reporting device for detection of the transfusion situation.
Background technology
In hospital, have a large amount of patients to accept transfusion every day, and infusion-completed must in time be processed----pull out pin or change dressings, otherwise will cause adverse consequencess such as " blood backs ".And the timely processing of infusion-completed depends in time obtaining of infusion-completed information.The method of obtaining the information of completing of infusing commonly used has two kinds usually at present; A kind of nursing staff of being sets flow rate of liquid (drip number/minute) according to medicinal property and patient's state of an illness in advance, estimate the required time of transfusion, in time patrol again every patient's transfusion progress, but this method is not only loaded down with trivial details, nor reliable, the one, error is large, and the 2nd, unavoidable patient or its entourage have changed flow velocity midway privately, and estimation and practical situation that the guiding doctor protects personnel are not inconsistent; Another kind is to rely on patient or its entourage to observe at the scene the transfusion progress, calls out medical personnel and process when infusing approaching completing.
But because transfusion time is mostly grown (one bottle of 500ml liquid is generally all more than 1.5 hours), this is a no small psychological burden to patient and entourage thereof, neither is beneficial to patient's recuperation, also easy " causing delay ".
Summary of the invention
The object of the present invention is to provide the strong and comparatively cheap a kind of infusion alarm of cost of a kind of capacity of resisting disturbance.
A kind of infusion alarm is characterized in that, infusion alarm comprises: fixture, and be arranged at infusion alarming circuit on fixture; Fixture comprises the first fastening part and second fastening part that can mutually clamp; The infusion alarming circuit comprises battery case, two detecting electrodes, capacitive touch chip, micro-control unit and alarm units; Battery case is used for the battery that accommodating other electronic devices and components to the infusion alarming circuit provide power supply; Detecting electrode is individually fixed in the inboard of the first fastening part, the second fastening part, for detection of the capacitance variations in tube for transfusion, and to the capacitive touch chip output detection signal; Capacitive touch chip is used for the detection signal according to detecting electrode, starts micro-control unit; Micro-control unit is used for controlling alarm unit and reports to the police after starting; Alarm unit is installed in the opening part of the first fastening part, is used for sending alarm signal under micro-control unit controls.
Whether the specific embodiment of the present invention adopts capacitive way to detect tube for transfusion liquid, and capacity of resisting disturbance is stronger, and therefore, the detecting reliability of testing result is higher, and cost is also lower; And because being detects in the tube for transfusion outside, need not contact medicine, therefore also can not produce medicine and pollute.The use of this infusion alarm will make traditional infusion management pattern be changed, and reduce medical personnel's labor intensity, can avoid again patient and entourage thereof the unnecessary participation in infusion management simultaneously.
