Abstract
Abstract A system for cleansing a patient's ear is disclosed. This system contains a control unit, a portable applicator, and a means for modifying the flow of fluid from the device when temperature or pressure limits are exceeded. The control unit contains a heater, a pump, and control means for maintaining the temperature of the liquid within certain limits, for limiting the pressure of the liquid, and for varying the flow rate of the liquid. The portable applicator contains a handpiece, a nozzle which is connected to the fluid source and is mounted on the handpiece, and a means for providing a signal to the control unit.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
238 words
A system for cleaning a patient's ear, wherein said system is comprised of a control unit, a portable applicator, a transparent, magnifying shield connected to said portable applicator, means for lighting, means for producing a signal by actuating a control device, means for limiting fluid flow when a fluid pressure exceeds a certain limit, and means for stopping fluid flow when a fluid temperature exceeds a certain limit, wherein: (a) said control unit is comprised of a heater means and heater control means for maintaining the temperature of fluid within preset limits, a fluid supply line, a pump operatively connected to said fluid supply line to dispense said fluid through said supply line to said applicator, and flow control means for limiting the pressure of fluid from said pump according to said control signal; (b) said portable applicator is operatively connected to said control unit and is comprised of a handpiece, a flow-directing first orifice through said shield connected to said fluid supply line from said pump, and a signal generator to generate said control signal to said flow control means; (c) said means for limiting fluid flow when the fluid pressure exceeds a certain limit is connected to said fluid supply line and is configured to divert a portion of the fluid flow when fluid pressure limits are exceeded; and (d) said means for lighting is comprised of a second orifice disposed within said transparent, magnifying shield.
Claim 2
Independent Claim
238 words
A system for cleaning a patient's ear, wherein said system is comprised of a control unit, a portable applicator, a transparent, magnifying shield connected to said portable applicator, means for lighting, means for producing a signal by actuating a control device, means for limiting fluid flow when a fluid pressure exceeds a certain limit, and means for stopping fluid flow when a fluid temperature exceeds a certain limit, wherein: (a) said control unit is comprised of a heater means and heater control means for maintaining the temperature of fluid within preset limits, a fluid supply line, a pump operatively connected to said fluid supply line to dispense said fluid through said supply line to said applicator, and flow control means for limiting the pressure of fluid from said pump according to said control signal; (b) said portable applicator is operatively connected to said control unit and is comprised of a handpiece, a flow-directing first orifice through said shield connected to said fluid supply line from said pump, and a signal generator to generate said control signal to said flow control means; (c) said means for limiting fluid flow when the fluid pressure exceeds a certain limit is connected to said fluid supply line and is configured to divert a portion of the fluid flow when fluid pressure limits are exceeded; and (d) said means for lighting is comprised of a second orifice disposed within said transparent, magnifying shield.
