The monitor has the advantages of low price, convenient use, multiple monitoring functions and wide adaptive range, being especially suitable for being popularized and applied in hospitals.
Description
This utility model belongs to technical field of medical instruments, particularly a kind of medical infusion electronic watch-dog that can carry out the Monitoring and Controlling caution to the medical infusion process.
At present, when medical institutions such as hospital, clinic did the intravenous drip treatment to patient, drop bottle was suspended on the sick bed upside, and the transfusion drip velocity is adjusted by medical personnel.In infusion process because factors of affecting, its drip velocity is changed, at this moment need by medical personnel find and again adjustment adjust.When the medicinal liquid in the drop bottle soon is totally lost, also need medical personnel or patient constantly to monitor, change the operation that bottle continues transfusion or stops to infuse so that carry out.By personal monitoring's control, medical personnel's labor intensity is big, and influences the quality of infusion treatment fully for whole infusion process.
The purpose of this utility model is to provide a kind of medical infusion electronic watch-dog for overcoming above-mentioned defective, and it can be controlled quantitative infusion, and to drip velocity whether depart from setting valve, stop dripping, transfusion state such as empty bottle sends alarm signal.
The purpose of this utility model is achieved in that the medical infusion electronic watch-dog is by casing, the scale lifting regulating mechanism, the photoelectric probe position adjusting mechanism, wiring board, fixed hook, cover is formed, its circuit is by the photoelectric sensing circuit of the displacement of scale being carried out Photoelectric Detection, photoelectric detecting signal is differentiated, the voltage of shaping is differentiated shaping circuit, can produce positive pulse or negative pulse and count results be judged and informs the signal processing circuit of warning circuit, adjustable clock circuit as time reference, multi-stage counter, warning circuit and circuit work power with auto-lock function are formed, and circuit work power voltage is direct current 5V.
The scale lifting regulating mechanism is made up of pull bar, stator, the guide rod of scale, spring, band hook.Quantitative scale is carved with on the scale left side, and the right is the quantitative grating of string, and the bottom, bottom right is a zero locatino grating.
The photoelectric probe position adjusting mechanism is made up of probe socket, quantitative pointer, adjusting screw(rod), quantitative adjusting knob, jump ring.Two pairs of Photoelectric Detection probes are housed on the centrage of probe socket left side, the quantitative grating of the corresponding scale of wherein a pair of probe, another is positioned at quantitative scale and the middle place of quantitative grating to probe.
The material of casing, cover can be metal or phenolic resins or modified polypropene or flame-proof ABS plastics.
The corresponding quantitatively scale in cover the right, quantitatively there is a vertically arranged rectangle transparency window at the pointer place, and its left side has the hole that passes of two through holes that show the display lamp signals and a speed adjusting knob axle.
The operation principle of this medical infusion electronic watch-dog is: according to the principle that spring pressurized load is directly proportional with its length, design weight one displacement converted mechanism.When the drop bottle that fills solution hangs on the hook, its weight is applied on the spring by pull bar and stator, and the spring compression is shortened, and the turn adjusting screw(rod) points to probe socket and gives the quantitative scale of putting (for example 500 grams).Along with the minimizing of liquid measure, compressed spring extends gradually in infusion process, and scale also moves on gradually thereupon.Utilize photoelectric detective circuit that the speed (promptly to transfusion speed) of moving on the scale is carried out monitor alarm.When the zero point on the scale, the grating rising arrived corresponding Photoelectric Detection probe positions, send alarm signal by photoelectric detective circuit.Because the spring pressurized is the gross weight of drop bottle Jia Neisheng solution when select adjusting the quantitative scale of scale, and when zero point, grating rose to the Photoelectric Detection probe positions on the scale, the stroke that scale moves just in time reflects the reduction of solution, and therefore, the weight of drop bottle and quantitative infusion are irrelevant.The drop bottle of solution is housed, and himself weight comes down to be eliminated when selecting to adjust quantitative scale.
The spacing of every grating fringe is actual to be the light and shade optical window of 1 unit gauge length, just means Unit Weight of spring loss of weight when scale whenever moves 1 unit gauge length, and photoelectric detective circuit utilizes moving of this equidistant grating to realize monitor procedure.
The Photoelectric Detection probe is made up of two groups of infrarede emitting diodes, phototriodes.Wherein do the transfusion speed detection for one group, another group is made quantitative infusion and is detected.
Be provided with an adjustable clock in the photoelectric detective circuit,,, the multidigit enumerator counted setting under the clock as the time reference of transfusion speed.When scale moves 1 unit distance and when producing a photo-electric control signal, signal processing circuit is judged the count value on the enumerator:, represent that then transfusion speed is slow excessively if numerical value is excessive; If numerical value is too small, represent that then transfusion speed is too fast.Above-mentioned two kinds of situations, circuit will send alarm signal, call nursing staff's speed governing transfusion speed.If transfusion speed is in limited range, then produce a control signal to the enumerator New count of laying equal stress on that resets.Because being one, the photosignal that displacement produced of scale depends on the quantitative of solution weight variation, so, when selecting to set transfusion speed, come down to adjusting to clock frequency.
When transfusion stagnation and empty bottle state took place, spring elongation speed was zero.The spill-over of multi-stage counter meter does not also receive the photo-electric control signal when going out, and at this moment, circuit will send alarm signal.
When zero point on the scale, grating rose to corresponding Photoelectric Detection probe positions, its photoelectric detective circuit sent alarm signal, represents that quantitative transfusion finishes.
Alarm device adopts music integrated circuit or common news to ring circuit.Three level modes are adopted in outer signal output; Low level is represented to devote oneself to work; High level is represented to devote oneself to work; Control level is represented alarm condition.
In addition, the running voltage of this monitor circuit is direct current 5V, and is battery-powered by 6V.Power pack is provided with the light current alarm device, when battery electric quantity can send the light warning signal near before exhausting.
This utility model adopts photoelectric detective circuit that weight one displacement conversion amount is carried out Photoelectric Detection, thereby reach supervision and control to the medical infusion process status, can arbitrarily control quantitative infusion, can be too fast to instiling, slow excessively, stop dripping, transfusion state such as empty bottle sends alarm signal, call the nursing staff in time to handle, this improves the infusion treatment quality and all has very big meaning alleviating nursing staff's labor intensity.This watch-dog can pass through its signal output interface and the supporting use of 20-50 door Centralized Controller, can be implemented in the interior transfusion state of night shift room and carry out centralized Control institute's control sick bed, can also insert computer system by its signal output interface, transfusion time, process status etc. is noted down, printed and other technical finesse, so that make doctor's advice relatively, check medical record, usefulness such as analysis of cases.This medical infusion electronic watch-dog owing to have manipulate easy, control function is many, wide accommodation, inexpensive being easy to are popularized, be particularly suitable for medical institutions such as each hospital, clinic and use.
