(2) consumables open infusion pump is divided into two forms:
1. drops type infusion pump: by the electronic eye to monitor the number of drops per minute, open consumables for different brand specifications for the infuser by clinical nursing staff infuser drip nozzle type adjustments related to the settings and then put into use. For the plastic material gravity infusion device extrusion fatigue characteristics, dynamic pressure characteristics caused by running needles are completely ignored.
2. Simple infusion pump: by the indicator or switch to distinguish the difference between the consumables, the hospital to replace the brand specifications of the consumables by the hospital equipment section or clinical nursing staff to carry out a simple standardization and then put into use. For the plastic material gravity infusion device of extrusion fatigue characteristics, the dynamic pressure characteristics caused by the running needle is completely ignored.
(3) Consumables open infusion pump advantages:
1. hospitals to replace the infusion pump consumables simple procedures;
2. manufacturers of after-sales service costs are low, there are clinical staff to complete the calibration of the replacement of consumables.
3. Clinical staff are simple to operate and it is easy to switch between two or three common consumables.
(iv) Disadvantages of open-ended infusion pumps for consumables:
1. nursing staff are highly susceptible to confusion when switching between multiple consumables;
2. the risk of rupture from crush fatigue and the risk of running needle alarms for plastic tubing consumables is not managed in a limited way.
3. The wide openness of core parameters such as the accuracy characteristics of consumables is potentially risky.
(E) Violations of open-ended infusion pumps for consumables:
1. According to the requirements of the IEC's safety management code for infusion pumps, which is the equivalent adopted in China, infusion pumps that use multiple specifications of tubing consumables should prominently display a unique identification of the brand specifications of the consumables.
2. The pressure characteristics of the consumables should be precisely managed and not open to adjustment by clinical staff.
3. The timing of consumable replacement (prior to fatigue rupture) should be alarmed.
It can be seen that the domestic infusion pump industry manufacturers simply claim that their infusion pumps "can be open to the consumables, can use ordinary gravity infusion set" is in fact a serious violation of the law, although catering to the clinical staff, "infusion pumps the simpler the better! Although catering to the requirements of clinical staff "the simpler the infusion pump, the better," but the hospital and patients at great risk of use. The momentum of the rapid development of such consumables open infusion pumps should be curbed as soon as possible.
