Abstract
Abstract An ultrasound generator and emitter suitable for use in ultrasound therapy has an electrical signal generator for charging an ultrasound resonator in an ultrasound head with electrical signals, which are converted into ultrasound energy to be emitted. The ultrasound head also includes an adapter element which electrically matches the particular ultrasound head being used to the electrical signal generator. The adapter is in the form of a removable adapter element which is electrically matched to the ultrasound resonator. The adapter element can be easily plugged into and removed from a circuit board in the ultrasound head. When the ultrasound resonator is replaced, the adapter element can be easily interchanged with an adapter element for matching the new ultrasound resonator to the signal generator.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
An ultrasound device comprising: an ultrasound head; an ultrasound transducer; an adaptation element electrically connected to said ultrasound transducer and means for removably mounting said ultrasound transducer and said adaptation element in said ultrasound head; electronic means electrically connected to said ultrasound transducer in a signal path which includes said adaptation element for generating electronic signals for driving said ultrasound transducer; said adaptation element including a plurality of electrical components having pre-set values for electrically matching said ultrasound transducer to said electronic means and wherein said means for removably mounting enables substitution of a new ultrasound transducer and a new adaptation element matched thereto whereby said new ultrasound transducer is electrically matched to said electronic means without further adjustment.
Claim 2
Dependent Claim
119 words
An ultrasound device comprising: an ultrasound head; an ultrasound transducer; an adaptation element electrically connected to said ultrasound transducer and means for removably mounting said ultrasound transducer and said adaptation element in said ultrasound head; electronic means electrically connected to said ultrasound transducer in a signal path which includes said adaptation element for generating electronic signals for driving said ultrasound transducer; said adaptation element including a plurality of electrical components having pre-set values for electrically matching said ultrasound transducer to said electronic means and wherein said means for removably mounting enables substitution of a new ultrasound transducer and a new adaptation element matched thereto whereby said new ultrasound transducer is electrically matched to said electronic means without further adjustment.
Claim 3
Dependent Claim
27 words
An ultrasound device as claimed in claim 1, wherein said components of said adaptation element comprise a plurality of ohmic fixed resistors mounted on an IC base.
Claim 4
Dependent Claim
158 words
An ultrasound device as claimed in claim 1, wherein said electronic means comprises: means for supplying current to said ultrasound transducer; an ammeter which measures said current supplied to said ultrasound transducer; voltage monitoring means for monitoring the voltage supplied to said ultrasound transducer; a multiplexer to which output from said ammeter and said voltage monitor are supplied; an analog-to digital converter having an input connected to an output of said multiplexer to which signals from said ammeter and said voltage monitoring means are alternatingly supplied by said multiplexer; and processor means having an input connected to an output of said analog-to-digital converter for controlling said means for generating electronic signals by comparing said signals from said ammeter and said voltage monitoring means to reference values and altering the operations of said means for generating electronic signals based on the amount of deviation of said signals from said ammeter and said voltage monitoring means from said reference values.
Claim 5
Dependent Claim
44 words
An ultrasound device as claimed in claim 1, wherein said values of said components of an adaptation element are uniquely matched to an ultrasound transducer so that said ultrasound transducer and said adaptation element form a unique pair adapted for use and replacement together.
Claim 6
Dependent Claim
31 words
An ultrasound device as claimed in claim 1, wherein said ultrasound head includes a printed mother board, and wherein said adaptation element is plugged into receptacles in said printed mother board.
Claim 7
Independent Claim
132 words
A method for substituting components in an ultrasound device having an ultrasound head which includes an ultrasound transducer and having a drive circuit for driving said ultrasound transducer, wherein said ultrasound transducer is removably mounted in said ultrasound head and an adaptation element which is electrically connected in a signal path between said ultrasound transducer is removably mounted in said ultrasound head, said method comprising the steps of: electrically matching said adaptation element to said ultrasound transducer before installation of said adaptation element and said ultrasound transducer in said ultrasound head; installing the matched ultrasound transducer and adaptation element as a pair in said ultrasound head; and removing the matched ultrasound transducer and adaptation element as a pair from said ultrasound head in the event of a substitution of said ultrasound transducer.
