Musculo-skeletal Disorders (MSD) are regarded as a serious occupational health problem; they are causing human suffering, numerous functional deficits, and a serious economic damage. In hospital and non-hospital care; shaping activities are frequent and repetitive, that lead to well-documented MSD, and involve awkward postures. Among painful or tiring positions; the shaping of portable infusion pumps (PIPs) is often cited. The aim of this work was to develop a motorized apparatus, able to cope with the identified problem.
The technical development is the product of an hospital-industrial cooperation. A project management methodology has been used:
a) identify needs of health professional;
b) identify issues and resources to be mobilized;
c) draft the specifications;
d) write a business plan;
e) a design stage;
f) build the virtual prototype P0 using a CAD software;
g) produce the prototype P1;
h) assess and optimize P1 in actual conditions (experienced operators);
i) cross-analysis and active feedback;
j) build of a fully operational version P2.
All along the assessment stage, several models of PIPs were filled and tested.
The apparatus is compact, lightweight, robust, easy to transport; its use is intuitive and no captive consumables are required. The range of application does not only concern PIPs; it can also be used for the filling of soft bags and PCA pumps. We present a video of a PIP (Baxter, LV10, 230 mL final volume) filled with a solution of ceftazidime; the average processing time is of about 4 min.
This concurrent engineering project was carried out in 18 months; the new apparatus was called Hedfill®. A version with rechargeable battery is also being developed. We believe that the issue of MSD, caused by the shaping of PIPs, is largely solved by this new solution.
