DESCRIPTION:
BRIEF SUMMARY
The invention relates to an applicator for the arrangement of an external catheter of a male urinary incontinence equipment, said catheter being of the kind comprising a soft elastic thin-walled, substantially cylindrical body portion which is open at one end and is joined at the other end with a narrowed drainage tube portion for connection with a collection bag, said catheter being supplied to the user with the body portion rolled up from the open end towards the drainage tube end, said applicator comprising an annular or tubular member of a resilient thin-walled material having a greater rigidity than the catheter and being designed for arrangement externally on the catheter.
For catheters of this kind having the shape of condoms problems frequently occur in practice with respect to the arrangement of the catheter as a result of the fact that the catheter which is delivered in a rolled-up condition and, having regard to the comfort of the user, is manufactured from a thin-walled very flexible latex material, is to be arranged on a normal flaccid penis. Since the users of such articles are often elderly persons under nursery or disabled persons, the arrangement must frequently be performed by the nursing personnel, but this in addition to hygienic problems is often considered psychically embarrassing to the users.
In order to remedy these disadvantages an applicator for use in the arrangement of an external catheter has been suggested in international patent application, publication No. WO81/03609. The applicator is delivered to the user with the catheter arranged on it in a flat condition so that a rather great application of pressure is required in use for expanding the opening of the applicator which might be difficult for elderly or disabled users.
Moreover, from SE published patent application No. 362,584 an applicator is known formed as a cylindrical envelope having two parts which are axially displaceable relative to each other, and in which the expansion of the catheter for its arrangement is conditional upon the generation of a subpressure by drawing out the inner part of the applicator. This known applicator which accommodates the catheter in its entire extension has a length which makes it less suitable for disposable use, and also in this case the operation requires a certain exercise of force.
On this background it is the object of the invention to provide an aiding means for use in the arrangement of the catheter with which a substantially simplified and safer arrangement of the catheter is obtained so that the arrangement may more frequently be performed by the user himself, even by patients suffering from reduced finger movability.
According to the invention this is achieved by means of an applicator which is characterized in that the annular or tubular member is designed so as to surround the catheter through an axial length from the transition between the body portion and the drainage tube portion corresponding substantially to the length of the penis glans, the end of said member facing the open end of the body portion being designed to retain the rolled-up portion of the catheter in the supply condition, whereas the drainage tube portion of the catheter is accommodated in a closed narrowed tube portion formed in extension of said annular or tubular member. By means of this applicator which is delivered as a disposable article together with the catheter the arrangement is performed in a simple way in that the drainage tube end of the catheter surrounded by said annular or tubular element is placed on the penis glans and held against it by a slight external pressure on the element itself without any contact with the off from the rolled-up supply condition, since the resilient thin-walled applicator has such an increased rigidity relative to the catheter that it stabilizes the shape of the drainage tube end of the catheter upon arrangement around the penis glans and, moreover, covers the glans due to its axial extension so that the rolling-off will take place over the length of penis on
