Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an endoscope storage case used for storing and transporting an endoscope.

Conventionally, as an example of this type of storage case for an endoscope, the case body is provided with an insertion groove into which the flexible tube (insertion section) and light guide conduit of the endoscope are fitted, and a part of this insertion groove is provided. By providing a series of recesses shallower than the insertion groove, and on the other hand, providing a protrusion for the pot base corresponding to the hinge recess on the cover, these recesses will be removed when the cover marked H is closed. There is one in which the part and the convex part fit together to hold and fix the =J flexible tube and the light guide 1ITi tube. However, with this type of tube, when attempting to insert the flexible tube and light guide conduit tube into the insertion groove, the user accidentally does not insert them securely, and a portion of the flexible tube remains protruding from the insertion groove and the cover is covered. If you close the cover or forcefully close the cover even if it is housed in the insertion groove, there is a risk that the flexible tube, which has weak mechanical strength, will be destroyed. In addition, in order to always fit the recessed portion and the convex portion correctly, it is necessary to carry out the manufacturing process with precision, which has the drawback of increasing the cost.

In another example, the width of a portion of the insertion groove is narrower than the outer diameter of the flexible tube and the light guide conduit. However, with this latter type, if the user inadvertently tries to take out the flexible tube after placing it in the insertion groove when using the endoscope, the flexible tube may be stuck in the narrow part of the insertion groove. There were cases where weak flexible tubes (hanging numbers) that were pulled too hard would break.

The present invention focuses on the above circumstances.1. The purpose of this design is to allow the endoscope to be easily stored, to safely hold flexible tubes etc. that have weak mechanical strength and require careful handling, and to be able to take them out safely (111). Another object of the present invention is to provide a storage case for an endoscope that is easy to use.

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

The corresponding sides of the outer box 4.5 are connected by hinges 6, so that they can be opened and closed in the same way as the structure of a so-called attache case. A handle 7 for carrying the device is attached to the outer surface of the outer box 4.

In addition, each of the surface portions 8 and 9 that are exposed to the outside of the case body 2 and the cover 3 and that correspond to the case body 2 and the cover 3 when the cover 3 is closed is formed flat. The juices are flowing so that they join together. The surface portion 8 of the case body 2 is provided with insertion grooves 15° 16 and insertion holes I7 into which, for example, the flexible tube I2, light guide conduit I3, and operation portion 14 of the bronchial endoscope II are inserted, respectively. There is. The flexible tube insertion groove 15 is formed in a closed loop shape in order to arrange the distal end portion of the flexible tube 12 in a loop shape. In addition, rectangular recesses 19 and 19, for example, are formed by cutting out the right and left side portions of the insertion groove 15 at a plurality of locations in the 'closed loop portion I8. They are connected. Further, the depth of the recessed portion 19.19 is formed to be equal to the depth of the insertion groove 15, as shown in FIG. 2, and this depth is larger than the outer diameter of the flexible tube Z2 to be inserted.

For example, it is set to 3 to 5 times. In addition, the insertion groove I5
The width of the flexible tube I2 is also smaller than the outer diameter of the flexible tube I2, for example, 2
It is formed to ~4 times the size.

A flexible fitting member 21 that crosses the insertion groove I5 is fitted into the recessed portions 19, 19. The fitting member 2I is formed of a relatively flexible and cushioning material such as cross-linked foamed polyethylene into a thick rectangular plate having a thickness equal to the depth of the insertion groove Z5 and the recesses 191 and 19. ing. The fitting member 21 crosses the L-shaped insertion groove 15, and both ends of the fitting member 21 have concave portions 19, , ? It is provided at the attachment/detachment opening so that it can be installed in a closed state by being tightly fitted into the housing 9 and locked by frictional force.
