Abstract:
Objective To produce a plastic ampoule with an opening that fits syringe adapters to allow solutions to be drawn up without needles (to avoid needle stick and sharps injuries) and to test the effectiveness of the new design in terms of residual fluid volume and risk of microorganism contamination. Methods Evaluation study based on laboratory research was adopted. For the experimental group, 30 ampoules based on the new design were produced by 3D printing. The ampoules were sterilized and filled with 2 ml sterile water. The sterile water was drawn up without the use of needles, and the wastage fluid (i.e., 2 ml minus the quantity drawn up) was calculated. A 1 ml aliquot of sterile water from each ampoule was dropped onto a nutrient agar plate, and the number of colony-forming units was assessed after 48 h. For each ampoule, the experiment was performed twice. Sixty 2 ml glass-packaged sterile water injections constituted the control group. The fluid was drawn up with a needle, and the superfluous fluid and number of colony-forming units were assessed, as in the experimental group. Results The mean wastage fluid was 0.06 ml, 95% CI was 0.05-0.07 ml in the experimental group and the superfluous fluid was 0.06 ml, 95% CI was 0.06-0.07 ml in the control group, there was no significant difference between the two groups (Z=-1.194, P=0.233). The number of colony-forming units was 8 in the experimental group and 4 in the control group, there was no significant difference between the two groups (P=0.224). Conclusions The newly designed plastic ampoule opening could help health workers to avoid needle stick and sharps injuries when drawing up solution. The wastage fluid and microorganism contamination levels met the required standards, indicating that the new design is suitable for clinical application.
