Two different designs for the public PCA model

Dispensing method

1. Nasal cannula

2. Oxygen mask

Display

1. Touch Screen

Touch Screen

2. Buttons

There is one LCD screen and a bunch of buttons (like ATMs)

Identification

1. Card

Patients are given cards that store information about their specific conditions. They can just tap their cards on a sensor on the public PCA. The sensor will read information in the cards and create an appropriate amount of medicine that patidents can take.

2. Handprint Scanner

Patients put their hands on a handprint scanner on the public PCA and the scanner recognizes patients' identities by reading their handprints. An appropriate amount of medicine is created according to information stored in the data base.

Storage

1. There is one central storage place where all the gas tanks are stored. There are many pipes that are connected from the central storage to different public PCAs spread throughout a hospital.

2. Each public PCA has its own gas tanks.

Some Major Change in Our Design

After talking to our TA Woojin, we decided to make one major change in our design.

Instead of focusing on all three of our designs (Hospital, Home, and Mobile), we decided to forget about the home design and integrate the hospital design and mobile design into one single system to be used in hospitals.

We thought that our design was somewhat not focused specifically and wanted to make our design as specific and targeted as possible.

After some discussion, we decided to have one design to be used publicly by many people and another design to be used by individual patients. The public design must contain some sort of data base to store information of different patients and the individual design should be more portable.

We are planning to have a total of 4 designs, 2 for the public design and 2 for the individual design.

We will meet tonight and write another post in more details.
