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


Refined drawing for mobile system (front and back)

Add power component*

"GOZINTO" diagram for the home system

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.

In hospital ideas:

identification scanner

vending machine like structure

varying dose amounts

At home ideas:

semi portable device

inflammation, chronic pain, increases body temperature.

constant online connection to hospital

automatic dialing of emergency service if body temperature is out of range or consistently high dosages have been administered.

body temperature sensing, doctor assigns dosage to specific temperatures, machine administers medicine.

height specific (individually modified) dose administration to allow easy access to medicine. ( some diseases may prevent or increase pain if patient has to pick up a pill or open a container)

liquid form. This avoids the complication of drinking water (which means the machine has to be near water). Faster absorption into the body.

can vary amount more accurately. however liquid may need to be shaken or replaced more often to maintain freshness.

can have pill form, water as part of the machine. pill is hard to swallow. however pill allows for us to control the speed of the medicine being absorbed in the body.

slight pressure to the tube causes the machine to dispense medicine.

Gas???

similar to laughing gas, xenon

light weight, machine is more portable and compact

under pressure (compressed), less refills

fast

varying dosages

directly to lung then brain

only requires breathing, no swallowing

taste is less obvious

carry more dosages

for hospital use,minimizes sanitation problems(no mouth contact).

Mobile:

smaller component of home device.

easily transportable

max of a daily dose

Gas: carry more dosages

small pressurized pain packets

inhaler type model, capsule tank

Customer:

young adults to senior

non bed ridden patients

patients with access to medical care

Safety:

gas in inside chamber, only the doctor/hospital can access. multiple protective chambers, to prevent leaks and unauthorized penetration.

doctor controls dosage through computer program that recognizes individual body heat.

warning siren if problem occurs.

emergency dial up connection all day long

approximate size:

hospital- basement containing pressurized gas, but substations the size of ATM machines located sporadically throughout the hospital. connected to basement by tubing.

Home device- tall and narrow (only one type of medicine and has to be taller than person) tall vertical heater size.

Mobile device size- inhaler, size of a aluminum coke can.

Electronics:

main control board- LCD screen/voice control/buttons(not likely)/ rolling ball ( like golf arcade game)

heat sensor

height sensor (hospital)

alarm system

hospital connection/doctor access

portable- charger

Energy sources:

electricity

wall socket

battery- portable

emergency backup power to prevent depressurization, medicine needed in a power outage.

We had our first out of class meeting today!
