Linearinfusionpumps
Linear infusion pumps are used for similar purpose as the infusion pumps - to
administer drugs. As opposed to the infusion pumps, however, they are modified for precise
dosing of small volumes, which are dispensed via a syringe placed in such a dispenser. The
substance in the syringe is pushed out via the injection dispenser’s arm.

Besides the actual medium drive, the infusion pumps and linear infusion pumps
contain other supporting systems controlling the correct functioning and correct
administration of the respective drug. The so called occlusion pressure sensor monitoring the
pressure of the medium within the set represents one of these systems. High value may mean,
for example, the obstruction of the set, its constriction, etc., and the other way round, low or
zero value may mean, for example, a disrupted or disconnected set. Another system is the so
called bubble detector, which checks the homogeneity of the dispensed mix. The presence of
a bubble may cause even severe medical complications, should such a bubble get into the
bloodstream. A deviation from normal state in these systems activates a visual and acoustic
alarm.
Generallegislation
STC (safety-technical check), which ensues from Law No. 123/2000 Coll., more
specifically from Chapter 27 thereof, is one of the most common activities of a biomedical
technician in a medical facility. STC stem from the necessity to check and verify the
parameters of medical devices in their clinical operation. This concerns devices with
a capacity of potential damage to the patient’s health in case of malfunction or impaired
