Definitions

  • Valve device in particular for a urological catheter
  • the invention relates to a valve device, in particular for a urological catheter with a housing having a passage opening for liquid, on which a connection piece for a catheter tube is arranged, and with a membrane closing the passage opening in the interior of the housing.
  • the urine is drained from the bladder using a permanent catheter either in the form of a permanent drain or intermittently by using a catheter plug.
  • the permanent drainage of urine from the bladder is generally perceived as a burden. Plugging the catheter in and out is a major problem for many patients, since it requires a certain skill. This poses particular problems for those patients who are severely limited in their manual dexterity. In any case, two healthy hands of the patient are required for plugging and unplugging. Removing the plug is usually made difficult by a plug that is too tight. There is also a risk of infection when the plug is put down. Incontinence problems continue to arise from improperly plugging the catheter.
  • the object is achieved in that in the passage opening there is provided an axially displaceable tubular valve opening part which can be actuated from outside the housing and which, with its end facing the catheter tube, penetrates the membrane in the open position of the valve device and can be withdrawn from the membrane in the closed position.
  • the membrane is arranged in the outflow direction of the liquid in front of the end of the tubular valve opening part facing the catheter tube.
  • actuation of the valve opening part from outside the housing causes the membrane to penetrate or withdraw from the membrane.
  • the housing and the connecting piece are preferably formed in two parts and firmly connected to one another, the membrane being arranged between the housing and the connecting piece.
  • the housing can be plugged or screwed onto the connector for the catheter, for example.
  • the tubular valve opening part is connected to a slide arranged on the outside of the housing, which engages in a latching device formed on the housing. Since the slide is connected to the valve opening part, a displacement of the slide inevitably also results in a displacement of the valve opening part in the housing either in the direction of the membrane in order to pierce it, or away from the membrane, so that the latter automatically closes the passage opening to the catheter tube.
  • the latching device ensures easy handling during the emptying phase of the bladder.
  • the latching device consists of latching elements which can be brought into engagement with corresponding latching elements formed on the slide.
  • the locking elements on the locking device are expediently designed as locking grooves and at least one locking element on the slide as a locking lug.
  • the tubular valve opening part opens or closes the membrane and ensures or prevents the urine from being discharged from the bladder via the catheter tube to the outside.
  • the latching of the slide in the closed position guarantees a secure closure of the catheter, which securely holds the valve device closed even with every movement, especially since an opening of the catheter is only achieved by actively moving the valve opening part through the membrane.
  • the slide is provided with a resilient handle part.
  • the resilient handle part is used for easier handling of the slide in order to move it along the locking device.
  • the resilient handle part can be easily gripped and actuated by a finger or a fingernail.
  • the tubular valve opening part has a tapering cross-section with its end facing the membrane or the catheter tube, so that the end of the valve opening part is formed in a somewhat truncated cone shape.
  • the membrane is provided centrally with at least one radially extending incision.
  • the membrane can have a cruciform incision in the center. Here, the incision of the membrane is pressed when it pierces through the valve opening part into a space arranged behind the membrane in the passage opening of the housing or the connecting piece.
  • the membrane consists of a material without a latex portion. Dispensing with a latex portion of the membrane material has the particular advantage that the membrane material and thus the membrane itself achieves greater stability, thereby ensuring a secure closure of the valve device, even with prolonged and multiple daily use. In addition, the risk of bacteria attaching to the membrane material is reduced and the protection against infection is improved.
  • FIG. 1 shows a longitudinal section through the valve device according to the invention in the closed state to the catheter tube
  • Fig. 2 shows a longitudinal section through the invention
  • Fig. 3 shows a cross section through the valve device of FIG. 1 along the line III-III and
  • Fig. 4 shows a cross section through the valve device according to Fig. 2 along the line IV-IV.
  • the valve device 1 comprises a housing 2 which has a nozzle 3 on one side.
  • a connector 4 is plugged onto this, an annular groove 5 on the connector 4 receiving a corresponding collar 6 on the housing 2 in a locking manner.
  • a schematically indicated catheter tube 7 is attached, which is inserted into the bladder of a patient.
  • a through opening 8 runs axially through the connecting piece 4, which on the one hand opens into the catheter tube 7 and on the other hand continues with a changing cross section in the housing 2.
  • a membrane 9 made of a latex-free material is arranged between the front end of the housing 2 and an expanded receiving section for the connecting piece 3 of the housing 2.
  • Centrally radially extending incisions 10 are made in the membrane 9, as is shown in particular in FIG. 3.
  • the passage opening 8 is provided with an extension 11 behind the membrane 9.
  • a tubular valve opening part 12 is inserted in the through opening 8 of the housing 2 so as to be longitudinally displaceable.
  • the end of the tubular valve opening part 12 facing the catheter tube 7 is tapered. This has two circumferential collars 13 in the center, which can move in an enlarged area of the passage opening 8 of the housing 2.
  • a catch 16 is provided on the slide 15, which engages in one of two corresponding catch grooves 17 of a catch device 18.
  • This locking device 18 is formed on the outer surface of the housing 2.
  • the slide 15 is located in a tapered section of the housing 2, so that the slide 15 does not protrude beyond the outer circumference of the housing 2. Furthermore, the slide 15 is provided with a resilient handle part 19.
  • FIG. 1 shows the valve device 1 in the closed state, the membrane 9 being closed and thereby preventing urine from escaping from the bladder via the catheter tube 7.
  • Fig. 2 shows the valve device 1 in the open state.
  • the tapered area of the valve opening part 12 penetrates the incisions 10 in the membrane 9, so that this area of the membrane 9 is slightly pressed into the extension 11 in the through opening 8 of the connector 4.
  • the incisions 19 of the membrane 9 clear the passage of the catheter tube 7. Now the urine can flow out of the bladder to the outside via the catheter tube 7, the passage opening 8 of the connector 4 and the tubular valve opening part 12.
  • the slide 15 is moved back into its position according to FIG. 1 in the reverse manner.
  • the membrane 9 automatically returns to its starting position and closes the passage opening 8 to the catheter tube 7.

Abstract

L'invention concerne un système de clapet, notamment pour cathéter urologique, qui comprend un boîtier (2) présentant une ouverture de passage (8) pour un liquide et auquel est raccordé un raccord (4) de flexible de cathéter (7). Ce système de clapet comprend également une membrane (9) fermant l'ouverture de passage (8) à l'intérieur du boîtier (2). L'invention concerne un obturateur de cathéter qui n'a plus à être enlevé et fonctionne selon un système de clapet. A cet effet, il est prévu dans l'ouverture de passage (8) une partie d'ouverture de clapet (12) tubulaire à déplacement axial et actionnable depuis l'extérieur, dont l'extrémité qui fait face au flexible de cathéter (7) pénètre dans la membrane (9) en position d'ouverture du système de clapet (1) et peut en être retirée en position de fermeture.
