Abstract

A urinary catheter comprising a tubular elongated catheter body for insertion into the urinary channel. Means are provided for oscillating the catheter body in at least one area. By oscillating the catheter the risk of spasm are reduced. At the same time oscillation reduces contact with theurethra walls, thus, making it easier and more reliable to perform catheterization.

Description

Oscillating catheter
Field of the Invention
The present invention is related to a urinary intermittent catheter having means for oscillating the catheter body.
Background
During urinary catheterisation of both male and females, certain levels of inconvenience can appear like strain and some times pain. For some people the inconvenience escalates and turns into spasms in the urethra. The problem often appear during introduction of the catheter and for those people facing spasms in the urethra, catheterisation of the bladder will not be possible at that time. Postponing of catheterisation can lead to higher risk for re-run of urine to the kidney.
Such known catheters are typically formed of a tubular catheter body, wherein it in one end is attached to a connector, e.g. by gluing or welding. The end where the connector is provided is commonly referred to as the distal end, while the opposite end is referred to as the proximal end and is the end initially inserted into the urethra.
The proximal end is usually rounded at the tip to prevent trauma to the muscosa of the urethra. Openings, also referred to as 'eyes', are commonly provided at the proximal end along the side of the catheter body. When the catheter is inserted the urine will thus flow through the eyes through the catheter body and out through the connector. The connector is typically a tubular conical element, which function as a handle for manipulating the catheter and as a connector to connect the catheter to other devices such as extension tubes or urine bags.
Summary
According to the present invention it has been realised that in order to ease introduction of a catheter into the urethra and especially to minimize spasm and thereby preventing further introduction of the catheter the catheter may advantageously be oscillated. This reduces the risk of spasm while at the same time reduces contact with the urethra walls, thus, making it easier and more reliable to perform catheterisation.
Within the present description the term oscillating should be understood broadly. Thus oscillating is not necessarily a periodically vibration but can be a random vibration or shaking of the catheter.
Thus according to one aspect of the invention a urinary catheter is provided comprising a tubular elongated catheter body for insertion into the urinary channel, comprising means for oscillating said catheter body in at least one area.
By oscillating the catheter body in at least one area it should be understood that the catheter may be oscillated in the proximal end, however, no oscillation will occur in distal end.
The oscillating means may be provided in a multitude of different ways. In one embodiment the means for oscillating said catheter body comprises a drive device and for driving a shaft wherein said shaft extends inside the catheter channel from the distal end of the catheter by towards the proximal end of the channel and the driver device is connected to the shaft at the distal end of the catheter.
This is a simple way to provide the oscillating means. Advantageously the drive device may comprise an electric motor rotating a drive wheel, which is connected to the shaft.
In order to provide an oscillating motion the driver device may simply rotate the shaft around the longitudinal axis of the catheter. In order to further enhance the oscillation a weight can be attached to the proximal end of the shaft. In another aspect of the invention an apparatus for oscillating a catheter is provided.
Usually a user will catheterise several time during a day using disposable catheters. Thus, instead of disposing the means for oscillating the catheter after each catheterisation the means for oscillating may be provided as a separate apparatus.
According to the invention an apparatus is thus disclosed for oscillating a catheter, wherein the apparatus comprises a drive unit for driving a flexible shaft extending longitudinal from the drive unit. A weight is arranged on the shaft. As previously described the weight will cause the shaft to vibrate when the shaft is rotated.
The drive unit is arranged in a housing from which the shaft extends. The housing further comprises means for releasable accommodating the catheter around the shaft.
I should be understood that the following invention is especially advantageous when using intermittent urinary catheters, since spasm and other complications during insertion may more frequently occur.
Brief Description of the Drawings
The invention is disclosed more in detail with reference to the drawing in which
Fig. 1 shows seen in section a first embodiment of a catheter according to the invention.
Detailed Description of the Present Invention Fig. 1 shows one embodiment of a urinary catheter 1 having a catheter body attached to connector 3 at the distal end 4 of the catheter body. The connector is surrounded by a housing 5 holding a driver unit consisting of a electro magnet 6, which by using alternating current function as an electrical motor and drives a drive wheel 7 in a rotational movement indicated by the arrow.
The drive wheel is connected to a flexible shaft 8 extending from the drive wheel towards the proximal end 9 of the catheter body. At the tip of the shaft a small weight 10 is provided.
When the driver unit is activated it will rotate the shaft 8 and the small weight will begin to vibrate in contact with the catheter body transferring this motion into the proximal end of the catheter body. The vibrating motion will disperse down along the sides of the catheter thereby causing the catheter body to oscillate.
This allows the catheter to more easily be inserted into the urethra for draining urine (not shown) through the inlet eye 11 at the proximal end of the catheter and out through the outlet opening 12.
As a catheter a traditional PU catheter is used. Inside the catheter the shaft is arranged. The shaft is disposable and made of PU. Alternatively the shaft can be made of other types of flexible polymer or carbon material.
To generate the oscillation a small weight is placed at the end of the shaft. The weight is positioned asymmetrically on the shaft. To adjust the amplitude level of the oscillation, the weight can either be placed close to the centerline of the shaft or asymmetrically, between 0,2mm and 0,8mm from the centerline. The weight is made of titanium and mass is 1 ,2g.
