safety

instructions

1 . WARNING: Explosion hazard

if

used in

the

presence

of

flammable

anesthetics.

2. WARNING:

For

continued

protection

against

fire

hazard replace

fuses

only

with

ones

of

the

same

type

and rating.

3. Read,

understand

and

practice

the

safety

and operating

instructions.

Know

the

limitations

and

hazards

associated

with

the

Ultrasound.

Observe

the

safety

and operational decals placed on

the

unit.

4. Grounding-Make

certain

that

the

unit

is electrically grounded by plugging

into

an

electrical

outlet

with

a ground terminal

receptacle

CU-ground

outlet).

Follow

the

National

Electric

Code.

5. The

lntelect

Model

225P/230P

should

not

be

connected

to

any

other

device when

in

use.

6.

CAUTION: Federal law

restricts

this

device

to

sale by,

or

on

the

order

of, a physician

or

licensed

practitioner.

7. The

generator

should

be

routinely checked

before

each use

to

determine

that

all

controls

function

normally; especially

that

the

INTENSITY

control

does properly

adjust

the

intensity

of

the

ultrasonic

power

output

in a stable

manner. Also

determine

that

the

TREATMENT

TIME

control

does actually

terminate

ultrasonic

output

power

when

the

timer

reaches zero.

8.

CAUTION:-Use

of

controls

or

adjustments

or

performance

of

procedures

other

than

those

specified herein may

result

in

hazardous exposure

to

ultrasonic

energy.

indications for ultrasound therapy *

Some indications

for

the

use

of

ultrasound

include adhesive capsulitus,

bursitis

with

slight

calcification, myositis,

soft

tissue

injuries,

shortened

tendons

due

to

past

injury, healing

scar

tissue

and

plantar

warts.

Ultrasouno

is

an

efficient

modality when used

for

the

treatment

of

all

types

of

joint

contractures

resulting

from

capsular

tightness

and

scarring.

Ultrasound

is

the

modality

of

choice

to

obtain

therapeutic

levels

of

heating

within

body

structures

covered

by

thick

layers

of

soft

tissue.

Neither

shortwave

or

microwave

diathermy

is able

to

heat

these

underlying

structures

to

produce

results

comparable

to

ultrasound.

contraindications for ultrasound therapy *

Ultrasound

SHOULD

NOT BE

USED

over

the

eyes

or

the

reproductive

organs. Also

ultrasound

SHOULD

NOT BE

USED

over a pregnant

uterus.

Other

contraindications

include

acute

infection

or

septis,

deep vein

thrombosis,

or

arterial

disease, and

over

anesthetized

areas

or

conditions

that

cause

impairment

of

sensations, such as chemotherapy.

Ultrasound

IS NOT TO BE

USED

over

cancerous

lesions.

uniform

pressure.

You

must

keep

the

applicator

moving during

the

treatment.

Failure

to

keep

the

applicator

moving may

result

in

description of ultrasonic field

The spatial

distribution

of

the

radiated field

is

essentially a collimated beam

of

ultrasonic

energy

having a cross-sectional area

of

8.5

CM2

for

the

10

CM2

sound head when measured

at

a point 5

millimeters

from

the

transducer

face.

The energy

distribution

within

the

radiated field is

2.4

W/CM2 maximum, and

takes

a generally conic

shape having decreasing

intensity

at

progressively increasing distance

from

the

face

of

the

transducer.
This field

distribution

applies

for

the

radiation

emitted

into

the

equivalent

of

an

infinite medium

of

distilled degassed

water

at

30

deg.

C.

and

with

line voltage variations

in

the

range

of±

1 0

percent

of

the

rated

line voltage. The

ultrasonic

field spatial

distribution

of

the

5

CM

2

sound head is essentially

the

same as

the

field

of

the

10

CM2

sound head.

instructions

1. To fully maintain compliance

with

Federal Regulation

Title

must

be

recalibrated

annually.

It

is

recommended

that

all

Chattanooga

be

returned

to

the

or

an authorized servicing dealer

for

repairs

or

recalibrations.

It

is also recommended

after

the

replacement

or

repair

of

any

major

component. (See

Section

for

Calibration

Procedures.)
