Rinsing device and method for the operation thereof

Номер: US20120006415A1
Автор: Thomas Baur
Принадлежит: Individual

The invention provides a rinsing device, in particular for endoscopy, comprising an electrically driven pump, in particular a peristaltic roller pump, as well as a method of operating such a device. A control device is provided to detect and/or adjust a flow rate. In order to avoid an excessively high pressure in case of an unintended stenosis, e.g. kinking of the supply tube, or also intended stenoses, e.g. insertion of a narrow rinsing probe, a current-measuring device is provided to detect a current being received by the pump. The control device is adapted such that when the flow rate exceeds a prespecified limiting value and at the same time the current exceeds a first predetermined current value, the flow rate is reduced to a safe flow-rate value.

Chemical liquid supply device and chemical liquid supply method

Номер: US20120241469A1
Автор: Toshio Takeishi
Принадлежит: Koganei Corp

A chemical liquid supply device has a pump provided with a pump chamber which is expanded and contracted by an elastically deformable bellows, and chemical liquid in a chemical liquid container flows into the pump chamber through a suction channel. The chemical liquid in the pump chamber is discharged through a discharge channel to a discharge nozzle. A looped circulation channel for returning the chemical liquid supplied from the pump chamber to the pump chamber is connected to the pump, and provided with an expanding and contracting portion. A filter for filtering the chemical liquid which is returned to the pump chamber is provided to the circulation channel. Since flow resistance of the filter is not applied to the pump when the chemical liquid is discharged from a discharge nozzle, it's possible to discharge a specific amount of chemical liquid from the discharge nozzle with a high degree of accuracy.

The rotary diaphragm pump has a flexible, resilient diaphragm band surrounding an elliptical frame within a case having four chambers surrounding an elliptical core. An articulating mechanism has a plurality of wheels traveling along the elliptical edges of the frame. The mechanism extends and retracts as the wheels move from maximum extension along the major axis of their elliptical tracks to minimum extension at the minor axis of their tracks. This mechanism drives a pair of actuator rollers along the inner surface of the diaphragm, periodically forcing the diaphragm into the surrounding chambers to produce the pumping action. Each chamber has an inlet port and an outlet port. The various ports may be interconnected to provide one or more multi-stage pumps in combination with one or more single-stage pumps, as desired. Two or more pumps may be joined in tandem to provide greater capacity from a single drive shaft.

A hydraulically driven diaphragm pumping machine (“pump”), in particular for water and difficult-to-pump materials, comprises at least two side-by-side pumping units. Each pumping unit comprises a hydraulically-driven pump cylinder ( 1,2 ) and a separate non-pump hydraulic drive cylinder ( 9,10 ). The pump cylinder ( 1,2 ) has a lower first end with a first inlet and outlet for fluid to be pumped and an upper second end with a second inlet and outlet for hydraulic fluid. The pump cylinder ( 1,2 ) contains a bellows ( 3,4 ) closed at its lower end and open at its upper end for communication with hydraulic fluid. The outside of the bellows ( 3,4 ) defines a space for fluid to be pumped. The bellows ( 3,4 ) of the pump cylinder ( 1,2 ) is arranged to be driven by hydraulic fluid supplied at its top end, in concertina like expansion and contraction to pump the fluid to be pumped adjacent the lower first end of the pump cylinder ( 1,2 ). The hydraulic drive cylinder ( 9,10 ) is placed side-by-side the pump cylinder ( 1,2 ). The hydraulic drive cylinder ( 9,10 ) has a lower first end associated with a hydraulic drive an upper second end containing hydraulic fluid communicating with the upper second end of the pump cylinder ( 1,2 ). The hydraulic drive terminates at its upper end with a drive piston ( 19,20 ) slidably mounted in the hydraulic drive cylinder ( 9,10 ). The hydraulic drives of the hydraulic drive cylinders ( 9,10 ) of the two pumping units are connected by a hydro-mechanical connection ( 25,27 ) designed to control drive of the hydraulic fluid to advance and retract the pistons ( 19,20 ) of each hydraulic drive cylinder ( 9,10 ).

An improved diaphragm type chemical dosing pumps can be designed as both a variable displacement accurate dosing pump and a fixed displacement accurate dosing pump. The improved dosing pump provides a required supply of pressurized fluid, to be called hereafter as process fluid, to an injection point against varying gas or liquid pressures. By eliminating the use of elastomeric sealing, the failing of the pump due to seal wear is eliminated. An internal pressure relief valve protects the pump mechanicals from premature failure. Use of a spring assisted suction assists positive suction for very accurate dosing. The working fluid is a driver fluid that is used to lubricate working components of the pump. The angled ports minimize friction losses to further improve pump efficiency and also eliminate building up of air pockets. 1.

An example of recovery catheter assembly comprises an actuator element and a mechanically radially expandable and contractible recovery device operably connected to the actuator element. The recovery device has proximal and distal blocking portions and a central portion therebetween. The recovery device is at least partially placeable in a first, radially collapsed configuration and in a second, radially expanded configuration by manipulation of the actuator element. When in the second, radially expanded configuration, the proximal and distal blocking portions have radial dimensions greater than the radial dimension of the central portion thereby at least partially defining a collection chamber at the central portion. 1. A recovery catheter assembly comprising:a first actuator element;a second actuator element;a mechanically radially expandable and contractible recovery device operably connected to the the first actuator element and the second actuator element, the recovery device having a proximal end operably connected to the first actuator element and a distal end operably connected to the second actuator element;the recovery device comprising:proximal and distal blocking portions at the proximal and distal ends thereof; anda central portion between the proximal and distal blocking portions;the recovery device at least partially placeable in a first, radially collapsed configuration and in a second, radially expanded configuration by manipulation of the first actuator element and the second actuator element so that when in the second, radially expanded configuration the proximal and distal blocking portions have radial dimensions greater than the radial dimension of the central portion thereby at least partially defining a collection chamber at the central portion, the manipulation of the first actuator element and the second actuator element comprises movement of the first actuator element and the second actuator element with respect to the recovery device.2. ...
