Double Pump Cassettes

Most arthroscopy pumps on the market use tubes instead of cassettes. Tubes need manual setup which can result in pump inconsistency since the tube position can vary from case to case, it is normally also more time consuming. Double Pump uses Cassettes instead of tubes. The cassette house is constructed to easily fit the cassette which makes them easy and quick to mount.

Double Pump can be operated in either single mode or Double Pump mode. If the Double Pump is operated in single mode a Double Pump Day Cassette and a Double Pump Single is used. The Double Pump Day Cassette can be re-used during one surgical day, and the Double Pump Single is only used for one procedure.

If the pump is used in Double Pump mode, a Double Pump Day Cassette and a Double Pump Patient Cassette is needed. The Double Pump Patient Cassette actually consists of two (2) parts, one Irrigation tube (equal to the Double Pump Single), and the Patient Cassette, please see drawing below.

Product Overview

The Cassettes are designed to easy fit the cassette house on the pump. The cassettes snaps into place with a click sound and are easily removed by unlatching the cassette with the lever. The Double Pump cassettes have some other unique features:

The patented algorithm which calculates the true IAP (Intra Articular Pressure). The Cassettes are packaged in trays instead of pouches, which both prevents from dropping on the floor, but also makes them easier to keep sterile.

Behind the Double Pump Patient Cassette, the SmartVision optical sensor is located. With this sensor the Double Pump can automatically adjust pressure and flow when blood or debris is detected.
