               Occupational Therapy Department, Queen Elizabeth Hospital, Hong Kong                                HOSPITAL AUTHORITY CONVENTION 2017
               Introduction
               3D printing allows occupational therapist to provide sophisticated splint and specific assistive devices to tackle patients’
               problems in activities of daily living. Four scenarios in applying 3D printing will be illustrated. Also, the outcome compared
               with conventional methods will be further elaborated.

               Objectives
               To determine the outcome of applying 3D printing in four scenarios:
               (1)  Continuous ambulatory peritoneal dialysis (CAPD) connective device
               (2)  Hand functional splint for amputated fingers
               (3)  Ear splint
               (4)  Needle assistive device
               Methodology
               First scenario
               Poor eye-hand coordination of patient may increase the risk of peritonitis when performing CAPD. A connective device could
               be precisely produced with 3D printing technology. The CAPD system was anchored on the connective device. The Tenckhoff
               Catheter was stabilised on the movable tracks of the connective device. By moving the catheter along the tracts, this ensures
               the connection process of Tenckhoff Catheter contamination-free .

               Second scenario
               A gentleman with four fingers amputated had limited hand function. By use of 3D printing, sophisticated parts with hinge to
               mimic little finger (L/F) were made. A dynamic functional splint was prescripted that allowed patient to control the mimicked
               L/F by wrist action.

               Third scenario
               Ear splint has been used to control ear keloid. However, the pressure reduces once the keloid decreases in thickness.
               A 3D-printed G-shape serial adjustable clip was provided according to the shape of keloid. Patient could self-adjust the
               pressure by turning the screw to accommodate the reduction of keloid size.

               Fourth scenario
               Self-injection is a challenge for patients with fair hand functions. Without good anchor over injector, patients encounter
               difficulty to hold and control the depth of needle insertion. A 3D-printed adaptor allowing precise configuration to fit with
               injector can solve the problem of fair hand function.

               Results
               First scenario                                                                                      Wednesday, 17 May
               More renal patients could perform CAPD by themselves with the connective device. The risk of peritonitis for the patients can
               also be reduced.

               Second scenario
               The hand function of patient was improved that one could grasp and release small size object and paper. Patient could also
               generate a pinch grip of 0.5kg and pick up 100g object.

               Third scenario
               The keloid size and pigmentation was reduced. Patient reported that the pressure of splint could be adjusted, and was more
               consistent compared with conventional design.

               Fourth Scenario
               Patient reported that the depth of needle insertion was well controlled and the custom-made design on wings of adaptor also
               improved the handling of injector.

               Conclusion
               3D printing does enhance our clinic service qualities in splinting and assistive devices prescription. It helps therapists to
               create a real product from an idea.
