Description

The full-automatic venous transfusion modulator of micro computer

This utility model relates to the full-automatic venous transfusion modulator of a kind of micro computer, belongs to technical field of medical instruments.

In the clinical vein transfusion, air admission vein in the time of will finishing for preventing to infuse, or continuous many bottles of transfusions have been developed multiple tramsfusion controller device at present, but their volume is big, carry inconvenience, and control accuracy is poor, function singleness, cost are higher, popularize and use very difficult.

The purpose of this utility model is in order to overcome above-mentioned shortcoming, propose a kind of reasonable in design, be easy to carry, the collection monitoring, regulate, reporting to the police is the multi-functional venous transfusion modulator of one.

In order to achieve the above object, this utility model now is illustrated by the following technical solutions in conjunction with the accompanying drawings.

Accompanying drawing 1 is a circuit block diagram of the present utility model.

Accompanying drawing 2 is circuit structure diagrams of the present utility model.

Accompanying drawing 3 is structural representations of the present utility model.

This modulator has a casing, and its front end has a panel, and there is a link (1) on the top, There is the groove of discharge pond assembling box (22) rear end, with battery cage knob (21) box is locked; Side There is the individual side cover (17) that connects with casing by little axle in section, can be around axle 180-degree opening, China ink Fei Shi pipe (15) is placed in the side cover (17), and the both sides of pipe are equipped with photoelectric sensor (16), Side cover is by snap close (19) and (20) locking; In the casing Circuits System is installed and machinery drives Moving part.

Be equipped with on the panel power switch (4), indicator lamp (2), green LED (3), Display screen (5), subtract key (7), add key (8), operation key (6), set per minute and drip number Button (9), alarm indication screen (13).

Circuits System comprises photoelectric sensor circuit, filtering shaping circuit, button inputting circuits, display screen, display lamp, warning circuit, chip microprocessor circuit.Circuit part is summarized as follows:

Various requirement at first will infusing passes through KDEC, KFUN, and KADD presets setup parameter to CPU, obtains the drop signal by photoelectric sensor from the Murphy's dropper both sides and enters U6.(be sent to simultaneously green LED make it is luminous) with high and low level.Export U5 to through filter shape, after U5 is anti-phase, enter the external counting pulse input end of CPU.Like this, the drop of liquid CPU that whenever drips obtains a count pulse, this pulse signal with preset the routine processes of setup parameter by CPU, from 4,8,10,11 foot output control pulses, by the U4 drive stepping motor.5,6,7 feet of CPU connect the drive circuit U3 of display screen simultaneously, export with serial mode by 7 feet of CPU again, show on display screen X1.

This circuit uses the chargeable source of 5V, when voltage drops to below the 4.3V, by the T1 circuit red indication diode is lighted.

Mechanical Driven partly comprises motor (12), and the leading screw on the motor shaft partly is equipped with nut (11), and it is to be embedded in the gate valve made from ABS plastic (14), and the gate valve front end is infusion rubber tubing (18).

When using this instrument, link (1) is suspended on the infusion bottle below, parallel with black Fei Shi pipe (15), press on and off switch (4), energized.Black Fei Shi pipe is put into side cover (17), and this side cover can 180 ° of activities, by side cover snap close locking (19) (20).Green LED (3) glimmers when whenever dripping a drop of liquid, sets per minute by button (9) and drips number, infusion bottle amount of capacity (is unit with the milliliter), and transfusion total amount.Perhaps set the infusion bottle amount of capacity, the transfusion total amount requires transfusion time.(its numerical values recited enters operation by (6) at last by adding key (8) and change by subtracting key (7).Single-chip microcomputer is according to the signal of photoelectric sensor (16), and the data that calculate per minute drop number and setting are (per 15 by Murphy's dropper of the conversion constants of per minute drop and milliliter are one milliliter and convert) relatively.Relatively the back is according to its positive and negative error, send the positive and negative rotation of pulse enable signal motor by chip microprocessor, the nut that drives on the motor shaft slides before and after the screw thread groove of screw mandrel upper edge, make gate valve also advance simultaneously, retreat, the infusion rubber tubing of its front end is compressed or is loosened, and it is accurately infused according to the parameter that sets.During this period, display screen (5) can select to show current per minute drop number, transfusion total amount and transfusion time.When the one bottle of liquid that sets drips off, send the flicker of chimes of doom (13) display screen, remind and change bottle.When the transfusion total amount that sets drips off, send the flicker of chimes of doom (13) display screen, remind and change bottle.When the transfusion total amount that sets drips off, remove and report to the police, outside the display screen flicker, the motor running clamps tube for transfusion, and transfusion stops.Prevent the air admission vein like this.If the transfusion fault causes fluid drips not down,, remind nursing staff's handling failure also with sound and light alarm.After transfusion was finished, display screen still can show the last various data of transfusion.Drip number as per minute, the total amount of infusing at last, the omnidistance institute time-consuming of infusing is for medical personnel relieve and case taking is provided convenience.

This machine uses No. 5 chargeable batteries of four joints to be assembled into box (22), and when cell voltage drops to 4.3V when following, the shinny prompting changing battery of display lamp (2) at this moment, can be stirred battery cage knob (21) and take off battery case and charge.

In sum, because this utility model is simple in structure, chip microprocessor stable performance, and control accuracy height, tool can be realized unmanned nurse transfusion in Real Time Control Function.The needs of accurate control transfusion speed have fundamentally been solved.
