Vezi

Needle Destroyer for Hospital and Pathological Laboratories Project carried at NID Ahmedabad, Gujrat India

Needle stick injury

Infections HIV HBV HCV Cancer and many more

Many articles were read and found, recuse of needles used causing killer infections like HIV, HCV etc...and few articles talks about needle stick injuries

Needle Destroyer is Very Important to Avoid Infections and Reuse of Needles and Syringes.

Product Life Cycle Mapping for Needle Destroyer

Existing product comparison and inferential analysis ASCO

Form is not pleasing Sharp edges on cutter is not advisable Blending of metallic strip in between large mass of plastic is aesthetically disturbing Regarding needle collector, it is having good signifier There is no indicator Switch is also not having monotony with product Regarding graphics its very poor Surface graphics provided may lead to place for stagnation of blood and other stray marks

Red box brand

Form is Basic but fillets are appreciated Color shows dangerous one can appreciate that but medical use ?

Also if any star marks of blood on body panel cant be identified.

Embossed graphics may lead to stagnation of blood stray marks Steel strip provided not goes with product Screw may get corroded upon usage Thin and bad knob for drawer Switch is accessible but it looks like assembled and it also looks like it is not done for it.

Needle burner and syringe cutter are different and needle burner is provided with cover and it is big?

Body panel is appreciated because of plastic material Extra material in assembly look bad Yellow light indicator is there! But not highlighted

NET brand

Form is appealing Color is shuttled Graphics is looking cheap, like sticker Steel strip provided not goes with product Slot to drawer Switch is accessible but it looks like assembled and it also looks like it is not done for it.

Needle burner and syringe cutter in same slot Body panel is appreciated because of plastic material Sharp edge near burner ?

No indicator? Are the natural sound act as feedback of process

X brand

Form is Basic Black Color is not suggestible to be used in medical purpose Small and unwanted graphics Poor built product and can be seen in alignment of nozzle cutter Needle burning by straight aligning Nozzle cutting in perpendicular direction Cutting action may lead to instability of machine
