Definitions

  • the present invention is related to a urinary intermittent catheter having means for oscillating the catheter body.
  • 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.
  • the catheter 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.
  • oscillating should be understood broadly. Thus oscillating is not necessarily a periodically vibration but can be a random vibration or shaking of the catheter.
  • a urinary catheter comprising a tubular elongated catheter body for insertion into the urinary channel, comprising means for oscillating said catheter body in at least one area.
  • the catheter body 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.
  • 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.
  • the drive device may comprise an electric motor rotating a drive wheel, which is connected to the shaft.
  • the driver device may simply rotate the shaft around the longitudinal axis of the catheter.
  • a weight can be attached to the proximal end of the shaft.
  • an apparatus for oscillating a catheter is provided.
  • the means for oscillating may be provided as a separate apparatus.
  • an apparatus 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.
  • Fig. 1 shows seen in section a first embodiment of a catheter according to the 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.
  • the driver unit 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.
  • a traditional PU catheter is used inside the catheter. Inside the catheter the shaft is arranged.
  • the shaft is disposable and made of PU.
  • the shaft can be made of other types of flexible polymer or carbon material.
  • a small weight is placed at the end of the shaft.
  • the weight is positioned asymmetrically on the shaft.
  • 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.

Abstract

L'invention concerne un cathéter urinaire comprenant un corps de cathéter allongé tubulaire adapté pour être introduit dans le canal urinaire. Des moyens sont disposés pour faire osciller le corps de cathéter dans au moins une zone. En faisant osciller le cathéter, les risques de spasme sont réduits. En même temps, l'oscillation réduit le contact avec les parois de l'urètre, rendant ainsi plus facile et plus fiable la mise en place du cathéter.
