Description
One, technical field
This utility model belongs to the monitoring infusion technical field, is specifically related to a kind of multifunctional transfusion guard and alarm device.
Two, background technology
Venous transfusion is a kind of mode common in the disease treatment.Because transfusion time is very long, when changing liquid feeding and transfusion termination, change liquid feeding or extract syringe needle as untimely, the air admission human body promptly can bring life danger, in addition in the infusion process, occur other situations such as leakage sometimes, need in time notify medical personnel to handle, thereby all need someone guard specially generally speaking.In addition, special or critical patients for some, as the heart disease people, its transfusion speed needs to be controlled especially, otherwise, also can bring life danger, therefore also need the special messenger to guard especially.Obviously, it is time-consuming that artificial monitoring accounts for the people, nonetheless, and also unavoidable carelessness and cause patient's misery or malpractice.
In order to solve the problem that artificial monitoring brings, people have researched and developed venous transfusion monitor device various in style.The major function of these devices is concluded: report to the police when transfusion stops, close infusion pipeline simultaneously; Can indicate number of infusion drops, the wireless transmission alarm signal.And the design principle and the structure that obtain these functions also have nothing in common with each other, and as sensing mechanism capacitance level gauge are just arranged, lever weighing and sensing, spring tension sensing, probe sensing contact, correlation photoswitch etc.; Controlling organization or employing on-off switch formula, non-logical promptly disconnected, or adopt the non-commentaries on classics of peristaltic pump promptly to stop; And on its functional circuit, all adopting electronic hardware to take structure, its circuit structure then has nothing in common with each other.But these install most function singleness, promptly only possess above-mentioned wherein a kind of function, even possess above-mentioned two kinds of functions simultaneously, can not monitor the variation of number of drops in real time, and compare, or report to the police with setting value, automatically close simultaneously, or automatically adjust to recover normal; Can not in remote alarming system, show berth, be convenient to medical personnel, differentiate and judge contingent problem, to take measures areput according to this berth patient.
Three, summary of the invention
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of multi-functional transfusion guard and alarm device is provided.
The multi-functional transfusion guard and alarm device that this utility model provides, comprise signal gathering unit, centralized control unit, regulate performance element, onsite alarming unit and remote centralized alarm unit, signal gathering unit is transferred to centralized control unit with the signal of gathering, centralized control unit with signal processing after, as required more respectively to regulating performance element, onsite alarming unit and remote centralized alarm unit send instruction, carry out adjusting respectively by it, onsite alarming, the function of remote alarms, it is characterized in that also comprising a digital display indicating member, this digital display indicating member links to each other with centralized control unit, signal gathering unit is made up of a reflective photoelectric sensor and fixed clamp device, is installed on the Murphy tube of infusion pipeline; Centralized control unit by a single-chip microcomputer with form with its input circuit that links to each other respectively, time reference circuit, infusion flow preinstalled circuit, infusion flow display circuit, warning circuit, adjusting executive circuit and reset circuit; Regulate performance element and form, be placed on the infusion pipeline by actuator and controlling organization; The digital display indicating member is to be made of LCD MODULE; The onsite alarming unit is to be made of light emitting diode; The remote centralized alarm unit is made up of radio receiver, light emitting diode, computing circuit, music module and speaker.
During use, medical personnel can be according to patient's the situation and the kind of institute's loading liquid, at first, signal gathering unit is installed on the Murphy tube of infusion pipeline, in the usual way patient is infused then by the default infusion flow of the infusion flow preinstalled circuit of centralized control unit.When drop passes through Murphy tube, the reflective photoelectric sensor of signal gathering unit is about to number of drops and converts electric impulse signal to, input circuit by centralized control unit flows to single-chip microcomputer, the time reference that single-chip microcomputer provides according to the time reference circuit, will be after the signal that the unit interval obtains be handled by the interior software program of establishing, on the one hand the flow of current transfusion is sent on-the-spot demonstration information by the infusion flow display circuit to the digital display indicating member, compare with the default infusion flow of infusion flow preinstalled circuit on the other hand, if because of transfusion finishes or the leakage-stop liquid fault causes infusion flow and setting value when inconsistent, then give onsite alarming unit and remote centralized alarm unit by the warning circuit output alarm signal, send and close fluid-delivery valve gate signal or valve regulated signal and give and regulate performance element and carry out handling failure by regulating executive circuit simultaneously.Cause closing the transfusion valve if break down because of transfusion, treat that medical personnel are according to the troubleshooting that occurs after, can make digital display indicating member indication reset by reset circuit.
The utlity model has following advantage:
1, this utility model can show the venous transfusion flow by liquid crystal display screen is digital, and can artificially set automatic adjusting control, writes down the accumulative total amount of infusion automatically, and not only form is intuitively accurate, also is convenient to medical worker's control operation in accordance with regulations simultaneously.
2, this utility model can judge automatically whether the venous transfusion state is normal, and when transfusion finishes or break down, in time carries out scene and remote centralized and report to the police, and economizes the people, saves trouble, and can prevent effectively that malpractice from taking place.
3, this utility model can be regulated flow continuously automatically or close infusion pipeline automatically when venous transfusion finishes or break down, and races against time for waiting for that medical personnel handle.
4, advanced reflective photoelectric sensor has been adopted in this utility model design, and LCDs and computer software automatic program control technology greatly improve accuracy, reliability and the monitoring function of venous transfusion.
