1. The brand specification and registration number of consumables are not clearly marked;
2. Ordinary gravity infusion sets are prone to fatigue and fracture under the peristaltic extrusion of pressure infusion pumps;
3. The peristaltic mechanism of general infusion pump will destroy the elasticity of PVC plastic pipe of gravity infusion set, and the infusion volume and flow accuracy will drop sharply within two or three hours.
4. The pressure sensitivity is 4. PVC plastic pipe is very low, which can't meet the safety requirements of needle running alarm when it is matched with most infusion pumps.
5. The pill dose storage capacity of each gravity infusion set is very different. If there is no professional testing and restriction, it may have a great impact on the patient's pill dosage.
(2) When the JMS infusion pump OT70 1 was registered, it was explicitly required to use the original special consumables. If common infusion sets are used as supporting consumables in clinic, there are also the above five risks.
(3) OT70 1 infusion pump has opened the parameter setting of infusion set specifications to clinic, that is to say, clinicians can set the parameter of 1mm=( 15~60) drops on a single package of infusion set, thus achieving the purpose of maintaining the accuracy of volume and flow to a certain extent. However, the following risks still exist.
1. The drop number parameter 1mm=( 15~60) on the single package of infusion set is greatly influenced by factors such as liquid type, and the error is above 30%.
2. The risks such as fatigue fracture of consumables, no alarm in needle operation and influence of pill dosage have not been improved at all.
(4) In order to overcome the risk factor that the parameter of 1mm=( 15~60) on the single package of infusion set is greatly influenced by the liquid type and other factors, OT70 1 opened the capacity adjustment parameters to clinicians, with the adjustable range as high as 30%. In this way, although the trouble of frequent alarm is reduced to some extent through technical measures. However, it brings more clinical risks. Because clinical nurses are allowed to make artificial adjustments of up to 30%, there is a huge risk.
(5) In a word, OT70 1 provides technical means for clinical adjustment when it is used together with ordinary gravity infusion sets. These measures can only increase some safety in dripping and pipeline leakage, but there are still great risks in terms of accuracy of flow rate, damage of consumables, alarm of needle leakage, influence of pill dosage and clinical misoperation.
