DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to an external urinary catheter for the relief of male urinary incontinence comprising an inner catheter member with a tubular discharge spout for connection with a hose, said catheter member being arrangeable, in use, in a position under the foreskin of a penis in surface contact with the head (glans) thereof, and a separate outer holder member for circumferential engagement with the external side of the foreskin to maintain the inner catheter member in said position.
For the relief of male urinary incontinence, external catheters are generally used in the form of condomlike tubular sheaths to be placed externally on penis and having a discharge spout which via a hose is connected with a urine collection bag.
Such external catheters are known in numerous designs and in many cases serve as a satisfactory solution of male incontinence problems. The complete envelopment of penis may, however, give rise to troubles, partly because the application which is effected by unrolling the catheter requires a certain length of penis, partly in use due to the fact that the envelopment of the full length of penis with the catheter which is generally fastened adhesively either by means of a separate adhesive strip or by means of an internal adhesive layer involves strain of the skin and the constantly humid environment from the delivered urine entail skin problems, Such as allergy and maceration and in worst case ulceration.
The application problem entails that conventional external catheters cannot be used by incontinence patients having a too small or retracted penis.
Published patent application GB-A-2075847 proposes an external male urinary catheter in the form of a relatively short funnel-like uridom device which is placed directly against glans penis throughout its length, but nevertheless envelops glans and is kept in place under the foreskin. Around a discharge spout of the device, an external sheath is fastened which after the application of the catheter is brought in abutment with the outer side of the foreskin so that the whole device is kept in place by the position of the foreskin between the inner catheter element and the external sheath.
As conventional catheters of the above-mentioned kind, said prior art urinary catheter requires a relatively accurate adaptation to the anatomy of the user and must thus, inter alia, be manufactured in various sizes. The manufacturing which may be effected by injection moulding is further complicated by the integrated design of the inner catheter member and the outer holder member. The complete envelopment of glans penis with the inner catheter member, whereby the proximal end edge thereof which is provided with a bead is placed against the relatively sensitive skin band between glans and foreskin, may in use give rise to considerable nuisance. Furthermore, the fixation principle requires that the outer holder member during application is rolled onto the outer side of the foreskin. In spite of this, there may be a risk that the catheter might fall off in use in the case of a pull, e.g. from the collection bag connected with the discharge spout, or compressive load from the delivered urine.
GB-A-2 126 483 discloses a urine ducting device in the form of a tubular member, e.g. of silicone rubber, which in use is arranged outside the glans in extension thereof, so that a rather severe extension of the foreskin is required to keep the tubular member in place by the arrangement of an adhesive strip or a strap member sandwiched between adhesive strips on the external side of the foreskin.
This device has thus a structure which would result in considerable discomfort to the user.
SUMMARY OF THE INVENTION
On the basis of said prior art it is the object of the invention to provide an external urinary catheter which through a further development of the fastening concept explained in the above GB patent application entails an easier application and appreciably improved use properties as regards a more secure fastening and reduced i
