During use, can in a plurality of wards of hospital, install one or more veins intelligent controller of infusing continuously respectively, add in nurse station and load onto a central display monitor, specifically with reference to following steps:

One, start earlier can begin transfusion work after the machine self check is errorless.For example: according to patient's state of an illness, prepared that 9 bags of medicines, 1 bag of fat milk, 1 bag of insulin drip slowly, 1 bag of normal saline washing pipe is with totally 12 bags of transfusion liquids.

The first step: rationally arrange the transfusion order according to the physical property of medicine.Take out 6 bags of medicines 1---the physical property according to medicine on 6 passages successively hangs on the suspension holdfast second layer tee T support, and normal saline is suspended on 7 passages, and insulin is suspended on 8 passages, remains 3 bags of medicines and one bag of nutritional solution.

Second step: assembling transfusion control valve and transfusion gather the mouth of pipe.That gets that the total mouth of pipe 66 that 8 root canal orifice arms are arranged hangs over the instrument below gathers mouth of pipe hook last 29, getting the total mouth of pipe 66 that 2 root canal orifice branched pipes are arranged again hangs over and gathers mouth of pipe hook last 29, mouth of pipe hook has respectively one of 2 road mouths of pipe and 8 road mouth of pipe like this, be exactly Zong the effect of the mouth of pipe 66 is aggregated into the liquid of each road transfusion on the pipeline, the below connects the patient by disposable transfusion device again, realizes the uninterrupted continuously transfusion of multichannel.Find passage 1, earlier the syringe needle in the transfusion control valve is inserted in the medicated bag mouth of pipe, see and have medicinal liquid to flow out from lower end tube for transfusion union joint 62 through the Mo Feishi dropper, then close the transfusion pipe clamp 61 in the tube for transfusion, the Mo Feishi dropper is pushed in the Mo Feishi dropper draw-in groove of passage 1, the shape of the shape of Maufee type dropper draw-in groove 22 and Mo Feishi dropper 58 is coincide.Check whether tighten card well, errorless, then press the card pipe reset key 26 under the Maufee type dropper draw-in groove 22, its effect is that motor 25 cuts out this passage automatically, wait command is to prepare next step instruction.Transfusion pipe clamp 61 opened see that the mouth of pipe has or not medicinal liquid to flow out, no medicinal liquid outflow illustrates that then motor is working properly, pathway closure.Next find 8 tunnel transfusions to gather the mouth of pipe, look for 65 pairs of the branched pipes of a mouth of pipe to connect.Channel hardware connects to be finished, and next is the setting of infusion data: the first step clicks the passage 1 in the arrangement of passages key of keyboard below, and aisle light is bright, and then expression can be carried out data setting.Set according to order from the bottom up, at first nethermost is heating setpoint button 39, the transfusion temperature can cause when surpassing 300ml below 7 ℃ that shivering appears in the patient, extreme cold of the limbs, local vascular spasm and pain, even it is phlebitis occurs, so necessary when medicine suitably heated.Add thermal control and be made up of external heating module 55, external heating module can heat at the transfusion device end, and temperature loss is little, heating-up temperature is accurate.Adding thermal control has an ambient temperature to show that 38 and design temperatures show 14.Connect the panel 20 of outer heating main body, click and add hot key, the bright expression of heating lamp can be provided with, digital input key 9 and adjust key 15 with data and configure temperature.

Up be the flushing infusion pipeline again, the transfusion that can not mix of some medicine is so will rinse tube for transfusion well.Press washing pipe and set button 37, the bright washing pipe data setting that carries out of lamp, washing pipe drips speed and has been set at a fixed value, required setting be exactly the washing pipe time, as no special requirement, the time is defaulted as 60 seconds, the button affirmation, operation is finished.

Preset value is set, and the control valve that uses in this example is to be 20 droplets/milliliter standard pipe, can calculate the transfusion total amount according to dripping a number.General medicine does not need set amount, but needs set amount sometimes as insulin, presses preset value setting button 34 and comes amount of infusion is set, and setting is finished definite.This passage is closed behind the scheduled volume of being totally lost when transfusion automatically, jumps and links next passage continuation transfusion.

Press drug code enter key 35, represent and to set when a drug code and a fast setting key are all bright, affirmation is set with controlling key.Drip and to occur dripping fast data on the fast display screen, check to press after checking to deposit key 12 in and confirm, need to change and then adjust key 15 with digital setting key and data and carry out data setting by right side change key as dripping speed, after finishing by depositing key 12 affirmations in.If having code to need not to set, medicine then can not skip drug code enter key 35, directly set button 36 by dripping speed, this moment the meansigma methods of coming out, if it is suitable just by depositing the key affirmation in, then set dripping fast numerical value as if improper, confirm by depositing key 12 in after setting is finished by data adjustment key 15.

So far, first passage is set and is finished, and by that analogy, requires to finish the setting of 2-6 passage according to transfusion.What the 7th passage hung is normal saline, and the transfusion control valve of then preceding 7 passages can gather the mouth of pipe with the transfusion of 8 road branched pipes and connect, and gathers under the mouth of pipe and connects the patient with disposable transfusion device.What the 8th passage hung is insulin, gathers mouth of pipe connection with the transfusion of another two branched pipes, gathers under the mouth of pipe and connects the patient with disposable transfusion device.So far connect and all finish.1-6 passage below has a passage to begin Pause key 41, presses the transfusion beginning, and motor is detected by two groups of photoelectricity pilot switches, command transfer is given single-chip microcomputer, single-chip microcomputer sends instruction and gives motor, and machine operation is adjusted and dripped speed to predetermined value, launches orderly infusion process.Whether there is a drop display lamp 16 passage key top, does not drip and glimmers, normal in order to observe a speed.Because insulin requirement imports simultaneously, press eight passages and begin Pause key 21, eight passages and begin to work independently, drip speed by setting, close automatically after dripping to scheduled volume.

The mode of operation of preceding 6 passages is: first road pathway closure of being totally lost, aisle light goes out, first passage drips fast display lamp and goes out, and second channel is started working, and the second channel display lamp begins flicker, when second channel is totally lost, need wash pipe, then according to setting, the 7th passage was opened one minute, automatically close after washing pipe is finished, jump to third channel and continue transfusion.When being passed to the five-way road, preceding four passages transfusion is finished, and display lamp goes out, and then can change at following medicated bag of preceding four passages of non-stop-machine situation, need not change the transfusion control valve.Set passage 1, passage 2, passage 3, passage 4 by the order of setting just now, after passage 6 transfusions are finished, can jump to passage 1 automatically and continue transfusion operation, finish until transfusion, all pathway closures, report to the police, the information transmission is given nurse station, waits for that the nurse comes to do transfusion and finishes processing.

After transfusion is finished, click each channel card pipe reset key 26, motor is opened, and takes off Mo Feishi dropper 58, total mouth of pipe 66 and medicated bag, inspection machine, and powered-down, transfusion is finished.

Because the Chinese patient means of receiving treatment are mainly venous transfusion, the amount of infusion of inpatient every day is generally more than five bags, so when design control, can become 4 passages, 8 passages and more multichannel type according to the different designs of principle and infusion channel.
