Description

  The present invention relates to an endoscope water supply apparatus.

An endoscope is generally configured so that water for cleaning the surface of the observation window can be ejected from the tip of the insertion portion, and a water supply bottle for storing the water is provided in the housing of the light source device. It is attached to the outer surface of a side wall (for example, patent document 1).
Japanese Patent Publication 1-446141 Figure 1

  In such a state, the water supply bottle used in the endoscopic examination room is generally formed of a translucent plastic or the like so that the remaining amount of the stored water can be visually recognized by seeing through the light.

  However, since endoscopy is generally performed in a dim state, it is difficult to check the remaining amount of water stored in the water bottle during endoscopy, and the observation window is cleaned. During this time, the water suddenly ran out and the endoscopy was interrupted where it was important.

  Therefore, an object of the present invention is to provide an endoscope water supply device that makes it easy to visually recognize the remaining amount of stored water in a water supply bottle even in a dim endoscopic examination room or the like.

  In order to achieve the above object, an endoscope water supply device according to the present invention includes a translucent or transparent water supply bottle for storing water to be ejected from the distal end of an insertion portion of an endoscope. , A floating index is provided which floats on the surface of the water stored in the water bottle and is displaced with the displacement of the water surface and is visually recognized from the outside of the water bottle.

  In addition, the outer edge of the float indicator is formed in a shape along the entire circumference of the inner peripheral surface of the side wall of the water bottle, and an indicator line of a color different from the surrounding is provided on the outer peripheral surface of the float indicator in accordance with the position of the water surface. Visual recognition is easy.

  In addition, the floating index may be formed with a sealed space in which air is enclosed, and the floating index has a through-hole through which a water supply pipe for sending water stored in the water supply bottle passes vertically. It may be formed.

  According to the present invention, by providing a float indicator that floats on the surface of the water stored in the water bottle and is displaced along with the displacement of the water surface and is visible from the outside of the water bottle, a dim endoscopic examination room is provided. In such a case, the remaining amount of the stored water in the water bottle can be confirmed by visually checking the floating index from the outside of the water bottle, so that the endoscopic inspection can be prevented from being interrupted due to sudden water shortage.

  In an endoscope water supply device having a translucent or transparent water supply bottle for storing water to be ejected from the distal end of an insertion portion of an endoscope, the surface of the water stored in the water supply bottle is floated and displaced. Accordingly, a floating index that is displaced and visually recognized from the outside of the water supply bottle is provided, and an index line of a color different from the surrounding is provided on the outer peripheral surface of the floating index in accordance with the position of the water surface.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 3 schematically shows an endoscope water supply apparatus according to an embodiment of the present invention, and an endoscope connector 1 is connected to a light source device 10. FIG. 4 is a front view of the light source device 10 with the water supply bottle 20 of the endoscope water supply device attached thereto.

  An endoscope connector 1 detachably attached to the light source device 10 is attached to the distal end of a flexible connecting tube 2 extending from an operation portion of the endoscope, and a light guide protruding from the connector 1. The connecting rod 3 is inserted into the light source device 10 side, and the light guide fiber bundle incident end face is positioned at the light condensing position of the light source lamp 11 arranged in the light source device 10.

  Reference numerals 4 and 5 denote an air supply pipe and a water supply pipe that are piped in the endoscope so that the tip opens toward the surface of the observation window at the tip of the insertion portion of the endoscope, and is arranged in the operation part in the middle It is opened and closed by an operating valve (not shown). Both the proximal ends of the air supply pipe 4 and the water supply pipe 5 are connected to a connection base 6 disposed on the side surface of the connector 1.

  An air supply pump 12 is disposed in the light source device 10, and its outlet hole 12 a opens in the upper half of the side wall of the housing of the light source device 10, and water for feeding into the water supply pipe 5 at a lower position. A water supply bottle 20 is stored.

  The water supply bottle 20 is formed of a translucent or transparent plastic material or the like, and the water supply pipe is provided inside the air supply pipe 23 upward from a bottle lid 21 that is detachably attached to the upper end portion thereof by screwing or the like. A double tube with a structure 24 is extended. The air supply pipe 23 and the water supply pipe 24 are each formed of a flexible tube. A connection pipe 22 is inserted into the outlet hole 12 a of the air supply pump 12 and communicates with the water supply bottle 20.

  FIG. 2 is an external front view of the water supply bottle 20, and FIG. 1 is a side sectional view. The inner end of the water supply pipe 24 is arranged in a state of opening near the bottom surface in the water supply bottle 20. A switching cock 25 is inserted in the middle of the water supply pipe 24 and can be switched to a state in which the air in the water supply bottle 20 communicates with the water supply pipe 24 located in the air supply pipe 23.

  With such a configuration, the air supplied from the air supply pump 12 is sent out through the air supply pipe 23 to the air supply pipe 4 of the endoscope, and at the same time, the inside of the water supply bottle 20 is pressurized with pressurized air. The stored water 30 in the water supply bottle 20 is sent through the water supply pipe 24 to the water supply pipe 5 of the endoscope, and air and water can be ejected toward the surface of the observation window (not shown).

  Inside the water supply bottle 20, a plastic material that floats on the surface of the stored water 30 in the water supply bottle 20 and is displaced along with the displacement of the water surface, and is visible from the outside of the water supply bottle 20 formed transparent or translucent. A floating index 26 formed by, for example, is provided.

  The floating index 26 is guaranteed to have a function of forming a sealed space 27 filled with air and floating on the water surface of the stored water 30. However, since the plastic material having a specific gravity smaller than 1 floats on the surface of the water, the floating index 26 can be configured without providing the sealed space 27 in which air is enclosed.

  The floating index 26 is formed with a through hole 28 through which a water supply pipe 24 for sending out the stored water 30 in the water supply bottle 20 passes in the vertical direction so that it floats even if the water surface of the stored water 30 changes. The indicator 26 does not interfere with the water supply pipe 24.

  The floating index 26 has an outer edge formed in a disk shape extending along the inner peripheral surface of the side wall of the water supply bottle over the entire circumference, and an index line 29 of a color different from the surrounding area is provided on the outer peripheral surface of the stored water 30. It is provided over the entire circumference at a position that matches the position of the water surface. In addition, when the index line 29 is formed of a fluorescent paint or the like, the visibility from the outside of the water supply bottle 20 is further increased.

  With such a configuration, the remaining amount of the stored water 30 in the water supply bottle 20 can be confirmed by visually checking the index line 29 from the outside of the water supply bottle 20 even in a dim endoscopic examination room or the like. It is possible to prevent interruption of the endoscopic examination.
