Abstract
Abstract The coupling agent dispenser serves to guide and, at the same, possibly to warm up the coupling agent, which is required for many medical examinations, directly during the examination from a reservoir to a diagnostic probe.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A mechanism for transporting a coupling agent useable for various medical examination such as ultrasonic and doppler examinations, the mechanism comprising: a moveable probe; a reservoir for holding a coupling agent; a flexible hose having an inlet end adapted to be placed in communication with said reservoir and an outlet end in communication with said probe; pumping means coupled to said reservoir and to said probe to pump coupling agent from said reservoir through said flexible hose to said probe for application to a patient; control means adapted to work with said pumping means, said control means being positioned in said moveable probe, said control means for controlling the flow of coupling agent from said reservoir to said probe; said pumping means providing transport of said coupling agent in solely one direction, from said reservoir to said probe; flexible electrical cable means coupled to said probe, said flexible electrical cable means for providing information signals relevant to the examination; and said flexible hose and said flexible electrical cable means being the sole physical constraint on movement on said moveable probe.
Claim 2
Dependent Claim
180 words
A mechanism for transporting a coupling agent useable for various medical examination such as ultrasonic and doppler examinations, the mechanism comprising: a moveable probe; a reservoir for holding a coupling agent; a flexible hose having an inlet end adapted to be placed in communication with said reservoir and an outlet end in communication with said probe; pumping means coupled to said reservoir and to said probe to pump coupling agent from said reservoir through said flexible hose to said probe for application to a patient; control means adapted to work with said pumping means, said control means being positioned in said moveable probe, said control means for controlling the flow of coupling agent from said reservoir to said probe; said pumping means providing transport of said coupling agent in solely one direction, from said reservoir to said probe; flexible electrical cable means coupled to said probe, said flexible electrical cable means for providing information signals relevant to the examination; and said flexible hose and said flexible electrical cable means being the sole physical constraint on movement on said moveable probe.
Claim 3
Dependent Claim
32 words
The mechanism of claim 1 and further including a heater at said flexible hose for heating said coupling agent as it passes through said flexible hose from said reservoir to said probe.
Claim 4
Dependent Claim
45 words
The mechanism of claim 1 wherein said control means is a valve capable of assuming an open state in which coupling agent flows through said hose from said reservoir to said probe or a closed state in which said coupling agent does not so flow.
Claim 5
Dependent Claim
45 words
The mechanism of claim 3 wherein said control means is a valve capable of assuming an open state in which coupling agent flows through said hose from said reservoir to said probe or a closed state in which said coupling agent does not so flow.
Claim 6
Dependent Claim
28 words
The mechanism of claim 1 wherein said pumping means includes a cartridge filled with compressed gas to pressurize said reservoir, said cartridge being in communication with said reservoir.
