With the advancement of medical science, the drugs, the key discovery would have been to inject them to the patient great precision is necessary. In injection, these drugs are generally two major problems there: one is the half-life of many of them is short and immediately in the serum level of influence, so much so that a few minutes delay, rush, or the lack of accuracy in dose injection. the effectiveness of the drug on the patient would be changed. Second, due to the small size of these drugs, the speed of injection also plays quite a lot on the effectiveness of the medications. so that with little error in the speed of injection, or medication effect, do not have the required, or because the effects of abuse, over dose, there will be.
Nowadays, devices several have been made that use a system microprocessor, accuracy, high speed and volume of injection, types of medications, etc. for different patients. Of the most commonly used of these devices. a variety of infusion D'iris perfumed pumps, pump, syringe, etc. PCA(for infusion of analgesic drugs), the pump thalassemia is the pump, insulin pump implant (inside the body are planted) can be named.
Based on the work of this machine, injection drug use syringe. Because generally, the inner diameter of the syringe, standard, and fixed. can be adjust the speed of the linear motion, plunger, syringe, the speed of injection can be controlled. Typically, these devices for injection of medications in volume, are used, because generally, from a syringe, 5 cc, 50 cc. Since the accuracy of this device is 0.1 cc/h. in use, they generally, the medications, the less diluted are the advantage. Because a lot of the cases, the volume of most fluids is very harmful and if possible the patient medications without the accuracy of the device to also eat on low volume to the patient the injection. have a significant impact on the quality of the treatment will be.
This issue has led, in part, cardiac, CCU, more of the pump, the syringe used to pump another, like infusion D'iris perfumed pumps.
Plastic syringe containing liquid in the part retainer is to be placed, an inner tube along with set holder (Giving Set) by a needle or canola (Cannula) into the patient's vein or directly into the stomach, he connected. When the flow rate of liquid was determined. پلانگر (Plunger) of the syringe under pressure, put up a fluid stream. Speed of injection (move پلانگر) dependent on the diameter of the syringe and the flow rate set for the pump. When the pump is working, the amount of the flow rate, volume, and pressure fluid constantly measured, and if an error in these parameters or other parameters of the other occurs? alarms, the machine operator will be will be.
Injection of high or even low a certain drug, it is possible to each patient, is very dangerous. needles plastic produced by تولیدکنندههای completely different to both of them. for this reason, pumps, to work with the type (Brand) of certain of the needles is determined (a variety of needles usable for the label on the device is determined, in this case, the errors are noticeable changes in the flow rate and the volume of the liquid when the needles unauthorized use. characterized by. The result of the use of pumps, injection syringe, etc. control the pressure of the liquid injectable and prevention of damage to the vessel of the patient during the possible increase of excessive injection pressure. High pressure, with alarms, closing, and obstruction ( ...
