Abstract
An expendable perfusion device with automatic alarm and cut-off functions is composed of puncture unit, perfusion tube, dripping hopper, flow regulator, perfusion needle, two measuring electrodes on said puncture unit and dripping hopper, alarm circuit, cut-off valve, computer, and computer network.
Description
One, technical field:
The present invention relates to a kind of automatic alarming, disposable transfusion system, belong to technical field of medical instruments.
Two, background technology:
At present, the clinical disposable transfusion device that is used to infuse is made up of perforator, tube for transfusion, dropping funnel, flow regulator, infusion needle.During transfusion, perforator is inserted in the infusion bottle,, decide by medical worker's experience or timing fully by flow regulator control transfusion speed, whether transfusion is finished also by manual observation, has sometimes because patient is sleeping and does not notify the phenomenon generation that causes backflow of blood at once.
Three, summary of the invention:
The object of the present invention is to provide a kind of automatic alarming, disposable transfusion system.
Technical scheme of the present invention is: a kind of automatic alarming, disposable transfusion system, form by perforator, tube for transfusion, dropping funnel, flow regulator, infusion needle and automatic infusion alarm and computer and host computer network, it is characterized in that: on perforator and dropping funnel, be respectively equipped with measurement electrode and electrode contact, be connected with automatic infusion alarm by lead respectively; On the tube for transfusion between perforator and the dropping funnel, be provided with the stop valve of band measurement electrode and electrode contact, be connected with automatic infusion alarm by lead; Automatic infusion alarm is connected with computer and host computer network.
The present invention is the alarm core with CPU, and alarm is constantly gathered the signal of disposable automatic transfusion device, and according to the gained signal, CPU decisions making rapidly by alarm.Can show transfusion speed in the infusion process be what drip/minute.It is when medicament is totally lost in the infusion bottle that infusion process finishes, and this alarm sends the voice report, the warning of pointing out this bottle transfusion to be totally lost, and red lamp flass is arranged on alarm.The delayed startup stop valve stops transfusion simultaneously.Above process can be passed through wired or wireless lan line, concentrates supervision on the computer of medical matters night shift room, and can further incorporate network into by host computer and carry out telemonitoring.
The present invention can use by separate unit, also can many even thousands of computer monitor systems of concentrating jointly by wired or wireless LAN of hundreds of.Adopt wireless lan function, make things convenient for the patient movable within the specific limits.Lan line can be do not gone up when separate unit or many application yet, just supervision can not be concentrated.
The present invention uses installation simple, easy to operate.Use and install: the electricity level is inserted corresponding socket, and upper tubing is bumped in the stop valve, and energized is used to install and both finished, and the automatic infusion meter just can enter duty.
Volume of the present invention is little, the power consumptive province.Owing to itself carry transformation, charging, storage function, when having a power failure, also can not influence its unit work because of electric network fault.Because with the 220AC power conversion is safe voltage 12VDC, Gu the use of automatic infusion meter is very safe.
Use of the present invention can solve the contradiction between a lot of doctors and patients, make doctors and patients in time understand therapeutic process, and therapeutic process all can be noted, in order to searching, can carry out telemonitoring at any time by network, alleviated medical personnel's workload simultaneously, the patient is because of receiving treatment that the situation that can understand transfusion timely also just can be felt at ease.

Five, the specific embodiment:
As Fig. 1, Fig. 2, shown in Figure 3, the present invention is made up of computer and host computer network 1, automatic infusion alarm 2 and disposable automatic transfusion device 3 three parts, automatic infusion alarm 2 is the alarm core with CPU, alarm is constantly gathered the signal of disposable automatic transfusion device, according to the gained signal, decision making rapidly by CPU.
The present invention has the characteristic of certain conductive capability according to the medicine drop, and certain resistance value is promptly arranged, and after measurement electrode is inserted in the drop, but adopts single bridge of direct current with regard to the resistance value in the detection of drugs drop, obtains a voltage signal.This signal is amplified, after the integer, after delivering to cpu controller and handling, can obtain a pulse signal, remove the driving time basic circuit with it, displaying it just can obtain transfusion speed.Remove to drive the stop valve circuit with it, just can immediately the transfusion stop valve cut out.Transfusion in the transfusion device is stopped,, getting ready for following bottle of transfusion simultaneously in order to avoid enter the problem that air brings in the transfusion device.
The use of automatic infusion meter has just been installed measurement electrode additional with employed disposable transfusion device is identical in the market on perforator and dropping funnel, measurement electrode is used for detecting the variation of medicine drop resistance value in perforator and the dropping funnel.Narration respectively below.See figure two, figure three, the measuring process of dropping funnel is: when the 1st dropping liquid of drop drops on the measurement electrode, measuring circuit is conducting immediately.To remember in the control unit cpu circuit after this signal amplification, the shaping, dropping liquid can flow away very soon, and along with the 2nd dropping liquid drops on the measurement electrode, measuring circuit is conducting equally immediately.This signal is remembered in the control unit cpu circuit after amplification, shaping.Can obtain the time pulse between the 1st dropping liquid and the 2nd dropping liquid thus by the computing of cpu circuit, this burst length both had been the time of every dropping liquid, removed the triggered time basic circuit with this pulse, just can obtain medication infusion speed.
The measuring principle of perforator and the measuring principle of dropping funnel are basic identical, but it is to be used for detecting in the infusion bottle whether also having pharmaceutical liquid, and alarm was not reported to the police when liquid was arranged, when in the infusion bottle during no liquid CPU can send instruction, report to the police immediately by alarm.Work process is as follows: after the measurement electrode on the perforator is inserted infusion bottle with perforator, measuring circuit is conducting immediately, this signal is remembered in cpu circuit after amplification, shaping, when having only the interior liquid of infusion bottle to be totally lost, both no liquid between the measurement electrode, the resistance between the detecting electrode can be infinitely great.Utilize this variation to change into a pulse by CPU, go to trigger voice alarm circuit, just can obtain the warning of no liquid in the infusion bottle, alarm sends the voice report, the warning of pointing out this bottle transfusion to be totally lost, and red lamp flass is arranged on alarm.
The transfusion stop valve closes the signal of valve, utilizes the alarm signal that perforator records in the control unit cpu circuit exactly, and through removing to trigger the stop valve control circuit after the time-delay, the time-delay triggered time is set as required, and the transfusion stop valve cuts out, and stops transfusion.
