Patent number: 7933817Abstract: Disclosed are methods of leasing or billing for the usage of a portable suction pump adapted for use in a suction-assisted would treatment system. The pump has means for recording time units corresponding to periods of time when the pump is operating and for providing reports of usage time. The pump further has means for detecting that the wound treatment system is operating normally so as to be compliant with standards for suction wound treatment, and for recording and reporting time of normal operation or compliant usage. The methods include leasing the pump at a payment schedule that is based upon the amount of actual usage time or the amount of compliant usage time. The lease payment may include an amount of pre-paid time units such that unused time units can be credited to a new or renewed lease for a replacement pump. The billing methods can also be based in whole or in part on a planned maintenance schedule for the pump.Type: GrantFiled: June 14, 2007Date of Patent: April 26, 2011Assignee: Boehringer Technologies, L.P.Inventors: Christopher L. Radl, Kevin P. Klocek, John Karpowicz, John R. Boehringer

Publication number: 20110077605Abstract: A pump system for applying negative pressure to a wound, including a flow monitor capable of detecting a deviation from a reference airflow rate provided by a controlled leak to determine whether the system is operating normally or abnormally, and a flow status annunciator to indicate a normal operating condition or whether an abnormal condition is a leak or an occluded line in the system. The pump system further includes a pressure controller for regulating operation of a pump to control pressure in the system at a range around a user-selected setpoint. The pump system may also include a waste collector and a level sensor for detecting when the collector is full.Type: ApplicationFiled: November 15, 2010Publication date: March 31, 2011Applicant: BOEHRINGER TECHNOLOGIES, L.P.Inventors: John Karpowicz, Christopher L.

Patent number: 7815616Abstract: A medical device is provided that encloses a wound and promotes wound drainage by suction. The device includes an enclosure to be placed over a wound, adhesively connected to the skin around the wound by a flange. Gauze type packing cylinders can be placed in the wound, and suction is provided either by a bulb type pump, or by a pair of regulators. When regulators are used, one alternates the suction that it provides, and the other is continuous, such that the level of suction is periodically varied. The suction facilitates the transfer of liquid from the wound to the packing cylinders and from the packing out of the enclosure. A leak detector is optionally provided.Type: GrantFiled: September 16, 2003Date of Patent: October 19, 2010Assignee: Boehringer Technologies, L.P.Inventors: John R.

Publication number: 20080177253Abstract: A wound contact device comprising a permeable material and a wound contact layer having voids extending through the contact layer to a depth in the permeable material. The wound contact layer can comprise a thin sheet or film forming a generally flat and smooth wound contact surface having essentially no discontinuities or gaps. The wound contact layer can comprise a thin sheet of highly calendered fabric forming a wound contact surface having a mean surface roughness in the range of about 0 microns to about 200 microns. In progressive wound healing, an embodiment of the wound contact device having the fabric contact surface is used in earlier healing stages and an embodiment of the wound contact device with film contact surface is used in later healing stages. The wound contact device is particularly useful in wound dressings for use in suction-assisted wound therapy.Type: ApplicationFiled: July 6, 2007Publication date: July 24, 2008Applicant: Boehringer Laboratories Inc.Inventors: John R.
