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.

Design Sketches

Rough sketches for mobile, home, and hospital systems

Here are some examples of what we will base our design on. The different components will all be combined in the best way possible ( logical, money saving, and space efficient. )

Examples of pressurized gas chambers. Our Chambers would more protected from the outside, either by being in a separate locked room in a hospital or in a larger hard to access chamber in the home. The mobile device would not be as protected to allow mobility and also the dosage contained inside the mobile device would not be fatal, eliminating health risks.

Hand scanner, important in the hospital device to allow recognition of specific individuals. This way specific dosage and medicine type can be administered to the patient. For confirmation the patient would also have to imput the last four digits of their SSN to ensure privacy and correct prescription.

body temperature scanner to detect varying pain levels and allow proper dosage administered to the patient. The doctor will input into the system the proper dosage required at each varying pain level determined by the device, which calculated pain from body temperature. Inflamed areas and pain has a higher temperature.

our gas detector will be directly linked to an emergency contact and the hospital will be notified. this is for safety. if their is ever a gas leak or a potentially hazardous fire is present near the gas chaimber the alarm will go off, sending out the imformation and projecting a loud warning alarm.
