WATER BOTTLE CAP ASSEMBLIES FOR AN ENDOSCOPIC DEVICE

BACKGROUND

The present disclosure relates to endoscope systems. More particularly, the present disclosure relates to water bottle cap assemblies, wherein the cap assemblies are operative for coupling a water bottle to an endoscope device in order to deliver sterilized water to the endoscope device.

Many invasive medical procedures that previously required major surgery are now performed using endoscopic instruments. Such instruments can provide an internal view of particular body parts, organs, or passages without requiring invasive surgery. Generally, an endoscopic instrument may include one or more channels through which miniaturized, flexible instruments can be inserted and advanced. The endoscope typically includes an elongated flexible insertion tube equipped at one end with an eyepiece or other viewing means and at the other end with an optical lens. The insertion tube transmits images or image-producing signals from the illuminated operative site to the viewing means to provide the instrument operator with full vision of the actions being performed at the instrument's working end.

The insertion tube of an endoscope also provides a flow passage for the delivery of fluid (e.g., liquid or gas) for irrigation, insufflation or other purposes. In conventional practice, it is necessary to provide a flow of sterile water across the optic lens to prevent the buildup of materials (e.g., surgical debris and body fluids) on the optic lens. This flow of water operates, in a sense, like a windshield wiper/washer assembly.

In common designs, an endoscopic instrument typically has a control body which is connected by a light guide tube to a light guide connector, which includes a plurality of connectors that can suitably receive various fittings. For example, the light guide connector can include a connector orifice that receives a grounding lug, a suction port, an air inlet, and a water inlet. As such, the air and water are delivered through the light guide connector, through the light guide tube and into the control body. Alternatively, the control body can also include a water port so as to allow water to be directly provided to the control body. Suitable valves are provided on the control body so as to control the flow of water through the control body and over the optic lens of the instrument.

SUMMARY

Embodiments of the present invention provide water bottle cap assemblies for use in endoscopy procedures. The inventive water bottle cap assemblies can be designed and shaped to function with endoscopic devices generally or may be designed and shaped to function with endoscopic devices having a particular structure unique to a single manufacturer of endoscopic devices. Similarly, the water bottle cap assemblies may be configured for use with a variety of different water sources. In light of their economical nature (and option for disposable, single or daily use), the inventive water bottle cap assemblies allow for provision of a secondary gas in an endoscopy. In one embodiment, the water bottle cap is configured to also support irrigation. These and other benefits of the present invention are more fully described herein.

In certain embodiments, the present invention provides water bottle cap assemblies that can be used with endoscopic devices. In particular, the water bottle cap assemblies allow for in-line placement between the endoscopic device and a water source. For example, the water bottle cap assembly may include a cap comprising a plurality of ports (e.g., two, three, four, etc.) and an engageable member (e.g., internal threads, a sealing ring, an annular sealing platform) configured to sealingly engage with a water source (e.g., a water bottle or suitable container for holding one or more fluids). The assembly also includes a plurality of passage members, each passage member coupled to a respective port so as to be in fluid communication therewith. The tubular members may be single or multiple channels for conveying fluid between the water source and the endoscopic device. In addition, the assembly includes an adaptor coupled to an end of one of the tubular members that is configured to engage with an endoscopic device. At least one of the tubular members may be configured to convey at least one fluid (e.g., water, air, or secondary gas) between the water source and the endoscopic device.

Further features and advantages of the invention will become apparent from the following detailed description made with reference to the accompanying drawings.
