The present application claims the benefit of priority to German Patent Application No. 10 2006 53 582.0 filed on Nov. 10, 2006. Said application is incorporated by reference herein.
The invention concerns a manual connector for a hose line that is used to connect the hose line to a counterpart.
Such a hose line can be used in particular to transport fluid or gaseous media in medical technology, especially also as low pressure or vacuum pipe to suction off body fluids or surgical debris.
The invention is particularly well suited to realize the suctioning of debris from the surgical field occurring during a laser cornea treatment or to maintain a vacuum during such a procedure. The lasers used here are especially femtosecond lasers.
During such an operation, the eye is affixed with a contact glass using vacuum, as described e.g. in U.S. Pat. No. 6,254,595 or U.S. Pat. No. 6,676,652. Since debris occurring during the laser treatment, such as lachrymal fluid, is suctioned off by vacuum and thereby could contaminate the device used to generate the vacuum, special measures are necessary to prevent the contamination of sterile parts of the treatment devices.
One option, as utilized by the patent holder of the above patents, Intralase Corp., Irvine, Calif., USA, with its device Intralase® FS, is to merely generate the vacuum mechanically, using a simple vacuum suction pump with pistons, which is connected to the contact glass by using a hose that is discarded together with the contact glass following the procedure.
If the vacuum, or the low pressure, is to be generated using a motor-driven suction pump, it must by all means be prevented that debris or fluids get into the suction pump; in this context, it is known to place a filter before the suction pump. Due to the required sterile environment, this is subject to special procedures, or it must be exchanged regularly, which requires considerable effort.
The invention addresses the problem of how to overcome the disadvantages described above and to provide a simple manually operated hose connector.
The problem is solved by the invention by providing a manual connector for a hose line to connect to a pressure- or vacuum-generating device with an additional functional element.
It represents an even greater advantage, if this additional functional element is a filter or a separator for water or liquid.
With a different aspect of the invention, this additional functional element can also be e.g. an RFID (Radio Frequency Identification) chip or a visually identifiable mark (e.g. color marking or similar).
The plug according to this invention is preferably fashioned as a locking Luer plug.
It represents an advantage, if the hose line cannot be disconnected from the manual connector.
Thereby, the invention assures a connection between the pressure or vacuum hose and the device used to generate the pressure or vacuum that is easy to handle and prevents that these become dirty or contaminated by the debris particles or fluids.
The invention is described below in two embodiments (
The invention is not limited to the embodiments with the connection to a contact glass, as described, but encompasses in general the integration of an additional functional element in a manual connector for a hose line.
