Description

  The present invention relates to an endoscope water supply bottle device for storing water supplied to an endoscope.

  In endoscopes for digestive organ examinations and the like, in general, an air / water supply conduit capable of selectively ejecting air and water is provided on the surface of the observation window at the distal end of the insertion portion. There is one provided with a water supply conduit for cleaning mucosal surface that can eject cleaning water toward the mucosal surface (for example, Patent Document 1).

  Such a mucosal surface cleaning water supply line has a simple structure in which a cleaning water injection port is provided at the proximal end of a water supply tube piped in an endoscope. Previously, a syringe was connected thereto. The water supply operation was performed manually.

However, since it is troublesome to manually perform the water supply operation using the syringe barrel during endoscopy, in recent years, the water supply tube extended from the bottle for storing the wash water is endoscopically viewed through the water supply pump. It is connected to the washing water inlet of the mirror.
JP-A-10-276968

  An endoscope water bottle apparatus used for such an application includes a water pump provided at the end of a water supply tube disposed through the lid body, the lid body being detachably attached to the bottle. The end of the bottle is open near the bottom of the bottle, and it is necessary to clean and disinfect the entire tube including the inside of the water supply tube before or after use. is there.

  And when washing the inside of the water supply tube, if the syringe barrel etc. can be connected, the washing water can be easily sent manually and washed, but in the conventional endoscope water bottle apparatus, Since the syringe barrel cannot be directly connected, it is necessary to connect a separately installed syringe barrel adapter to the pump connection base, and handling and management of members are very complicated and troublesome.

  Therefore, the present invention connects the syringe barrel without using an adapter or the like to the water supply tube attached to the end portion outside the bottle with the pump connection base connected to the water pump, so that the inside of the water supply tube is easily and reliably washed. An object of the present invention is to provide an endoscope water supply bottle device.

  In order to achieve the above object, the endoscope water supply bottle device of the present invention is provided with a lid detachably attached to a bottle for storing water supplied to the endoscope, and penetrates the lid. In a water supply bottle device for an endoscope in which a pump connection base connected to a water supply pump is attached to an end portion of the water supply tube arranged outside the bottle, and an end portion in the bottle is opened near the bottom of the bottle. The luer lock cap for the injection needle to which the syringe barrel can be connected is attached to the end portion in the bottle of the water supply tube.

  According to the present invention, by attaching a luer lock cap for an injection needle to which the syringe barrel can be connected to the end of the bottle of the water supply tube, the syringe barrel can be connected to the water supply tube without using an adapter or the like. The inside of the water supply tube can be easily and reliably washed.

  A lid body is detachably provided on a bottle for storing water supplied to the endoscope, and is connected to a water feed pump at an end portion of the water supply tube disposed through the lid body outside the bottle. In a water supply bottle device for an endoscope in which a pump connection cap is attached and an end portion in the bottle is arranged near the bottom of the bottle, a luer lock cap for an injection needle to which a syringe can be connected is connected to a water supply tube. Attach to the end of the bottle.

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 2, 1 is a water supply pump, and the tip of the water supply tube 2 connected to the discharge path side is a cleaning water inlet provided at the proximal end of a water supply tube for cleaning the mucosal surface of an endoscope (not shown) Connected to.

  Reference numeral 10 denotes a water supply bottle device for storing water supplied to an endoscope, and an outer end of a flexible water supply tube 13 disposed through a lid body 12 detachably provided to the bottle 11. A pump connection cap 14 that is detachably connected to the water pump 1 is attached to the portion (that is, the end outside the bottle 11).

  Further, the inner end of the water supply tube 13 (that is, the end in the bottle 11) is disposed in the vicinity of the bottom of the bottle 11 and can be connected to a syringe barrel not shown in FIG. A luer lock base 15 is attached thereto.

  FIG. 1 shows a water supply bottle device 10, and a lid 12 is detachably attached to an upper end opening of a bottle 11 for storing water supplied to an endoscope by screwing. The water supply tube 13 is divided at a portion penetrating the lid body 12 and connected through a metal connecting pipe 16. Reference numeral 17 denotes a nut for fixing the connection pipe 16 to the lid body 12.

  The injection needle luer lock cap 15 is made of, for example, a metal having high water resistance such as stainless steel or hard plastic, and is connected to the inner end of the water supply tube 13 by press-fitting (or press-fitting adhesion). Has been.

  The water supply tube 13 is arranged in a state where it is bent in the bottle 11 to such an extent that the injection needle luer lock cap 15 is placed on the bottom surface of the bottle 11, and the injection needle luer lock cap 15 is made of metal. Has a function of a weight that sinks the tip of the water supply tube 13 to the bottom of the bottle 11.

  In the endoscope water bottle apparatus of the embodiment configured as described above, when in use, the water in the bottle 11 passes from the luer lock cap 15 for the injection needle through the water supply tube 13 to the endoscope by the water supply pump 1. Supplied and sprayed toward the mucosal surface.

  When the endoscope water supply bottle apparatus is cleaned and disinfected before or after using the endoscope, the lid body 12 is removed from the bottle 11 and the luer lock cap 15 for the injection needle is removed as shown in FIG. The inside of the water supply tube 13 can be easily and surely cleaned and disinfected by connecting the syringe 20 containing the cleaning liquid or the disinfecting liquid to the luer lock cap 15 for the injection needle. As for 20, the outlet portion can be connected depending on the situation regardless of whether it is a luer mouthpiece type or a normal tapered tube type.

It is side surface sectional drawing of the water supply bottle apparatus for endoscopes of the Example of this invention. It is a side schematic diagram of the state where the water supply bottle device for endoscopes of the example of the present invention was connected to the water supply pump. It is a perspective view of the state which wash | cleans the inside of the water supply tube of the water supply bottle apparatus for endoscopes of the Example of this invention.
