Definitions

  • the check valve for drainage of fluid into the vascular system or into a body cavity for the treatment of hydrocephalus internus and extemus is fabricated of synthetic material and has a body with screw thread on each side.
  • a connector On the proximal side of the valve is screwed a connector, which has a cone and a cylindrical part to receive a proximal catheter, in addition to a screw thread for the fixing of a screw cap.
  • a shoulder serving as a stop for the screw cap and preventing shearing of the proximal catheter.
  • the connector has a longitudinal bore which drains the fluid into the catheter, the bore widens to a cone and this cone is obturated by a piston, which possesses four longitudinal slots.
  • a spring lays in the bore and can be adjusted by a regulating screw for the purpose of pressure calibration of the fluid.
  • the present invention relates to a check valve for drainage of fluid into the vascular system or into a body cavity for the treatment of hydrocephalus intemus and extemus.
  • Electrostatic charging of the material; slit valve and pumping device are made of silicone so that in the case of infection the bacteria adhere to the valve and make this a source of infection.
  • the first two mentioned valves are slit valves of silicone rubber, which allow an excess pressure in the valve an out flow and inhibit a back flow on an excess pressure outside the valve.
  • the principle and the materials used do not allow an exact calibration. On storage and later after application of the valves, changes occur and in the course of time the elasticity and thereby the calibrated pressure of the silicone rubber change.
  • the inlet and outlet catheters are, in all the valves described till now, fixed by means of ligatures on metal connectors of the valve. There is the danger of these connections being severed by the ligatures cutting into the catheter, by slipping off of the end of the catheter and by shearing off the catheter and may lead in this manner sooner or later to serious complications.
  • valves are constructed with materials which take up electrostatic charges and therefore, in the event of infection, bacteria adhere to the valve and cleaning can only be effected in rare cases by self-rinsing or active antibiotic rinsing by puncture.
  • valves for a single use and if they are to be removed for renewal they can never be replaced, because they cannot be sterilized or are not dismountable.
  • the object of the invention is to effect draining of cerebrospinal fluid by means of a check valve, with which it is sought to overcome the above mentioned inadequacies.
  • the valveaccording to the invention is characterized by the fact, that it is made of synthetic material and consists of a body which has a threaded end part, on each side, that on the proximal side of the valve is screwed a connector, which has a cone and a cylindrical part to receive a proximal catheter, and has also a threaded part, for the fixing of a cap, which has a cone different from the connector and clamps in this manner the proximal catheter on the connector, that on the connector is formed a shoulder which serves as a stop for the cap and prevents shearing of the proximal catheter, that the connector has a longitudinal bore which conducts the fluid from the catheter, that the bore enlarges to a cone and that this cone is obturated by a piston which possesses on its circumference four longitudinal slots for the flow of the fluid, that inside the piston'a spring is disposed, which is situated outside the stream of fluid, that the spring can be adjusted with a regulating screw for calibrating the pressure of the
  • FIG. 1 shows a longitudinal section through the embodiment of the invention
  • FIG. 2 shows a cross section along the line A-B of FIG. 1.
  • the valve consists of a body 1 of a cylindrical shape and which has in both end portions a screw thread 2, each of which receives a connector 3 and 4 which, preferably, are made of polyphenylenoxide, since this material is physiologically neutral, possesses good mechanical qualities, is stable to changes in temperature, is easily sterilized, has very good dimensional stability, is insensitive to electrostatic charges, has good chemical resistance to most of acids, bases, alcohols and water, and guarantees a constant flow of the cerebrospinal fluid.
  • the proximal connector 3 consists of an internal conical part 3b, a shoulder 30, that serves as a stop to a screw cap 13, a threaded part 3d, on which, the cap 13 is screwed, a cylindrical part 32, a conical part 3f and a bore 33.
  • the catheter 16 is disposed on the cylindrical piece 32 and the conical part 3f
  • the distal connector 4 is constituted by the same elements and parts 4b-f.
  • valvepiston 6 In the cylindrical bore 5 of the valve 1 is situated the valvepiston 6.
  • This piston consists of a conical part 8 and a bore 7, which receives a steel spring 11.
  • the valve piston 6 has four longitudinal slots 10 through which flow the fluid to be drained.
  • the conical part 8 enters the conical part of the connector 3a and closes the latter.
  • the spring 11 is positioned in the bore 7 away from the fluid being drained and presses the valve piston 6 into the inner cone 3a.
  • the pressure regulation is effected by means of the regulating screw 12.
  • This consists of a threaded part 124, four longitudinal slots 12b and a cylindrical part which extends into the bore 7 and regulates the spring 11. By this means the pressure can be regulated to within 2 cm of water.
  • the catheter On the proximal connector 3 the catheter is fixed with the screw cap 13 and no ligature is disposed there.
  • This screw cap consists of a conical part 13a the slope of which is different from that of the conical part 3f, a cylindrical part 13b, which clamps the catheter l6 and a threaded part 13c, which is screwed on the threaded part 3d.
  • the catheter 17 On the distal connector 4 the catheter 17 is fixed with the screw cap 14 which is constituted by the parts 14a -l4c in an analogous manner.
  • the fluid to be drained is led by means of the bore 43 in the connector 4 to the distal catheter l7. lf the fluid is now flowing through the catheter 16 in the direction of the arrow through the bore 33,
  • the above-described novel valve is so constructed, that by means of regulation of a spring, the pressure may be regulated individually for each valve.
  • the spring is situated outside the stream of fluid.
  • the stream itself is wide and has no dead spaces. No parts are intercalated in the fluid path on which fragments of tissue, fibrin and coagula may adhere and could introduce occlusions. Even storage for many years or multiple sterilizations do not alter the pressure calibration.
  • the novel valve is provided with conical connectors by which the catheter is fixed by a conical screwed cap; ligatures are no longer utilized. Slipping off of the catheters is impossible.
  • the connection is constructed so that the screwed cap is drawn on to a shoulder. In this manner it is ensured that the surgeons connection is made correctly. This means of connection is rapid and positive and also offers great advantages at the time of subsequent recatherizations.
  • the above-described novel valve which, except for the spring 11, is constructed entirely of synthetic materials, is in length and in diameter smaller than the known valves. This is mainly based on the fact, that with this valve a pumping device can be dispensed with; if it is taken in consideration that the possibility of pumping was at first developed for control purposes, it is superfluous with a well-installed and well calibrated drainage system.
  • a pumping-system does not ensure freedom of flow and the final diagnosis of a valve connection will always be determined clinicaly or by ventrical puncture by pressure measurement and isotope methods.
  • the pumping device introduces more disadvantages (size of the valve, dead spaces in the flow path, electrostasis of the silicone) than advantages.
  • a check valve for draining fluid into the vascular system or into a body cavity for the treatment of hydrocephalus internus and extemus comprising a cylindrical body having a longitudinal bore and which has inlet and outlet ends thereof with screw threads in said ends; a proximal connector having first screw threads in threaded engagement with the screw threads in the inlet end of said body and closing said inlet end, said connector having a cone shaped part insertable in an end of a proximal catheter, a cylindrical part with an external screw threads and a shoulder between said cylindrical part and said first screw threads, a screw cap which has a bore with an internal cone shaped portion on a different slant from that of said connector cone shaped part and a cylindrical portion being in threaded engagement with said connector cylindrical part external screw threads whereby said cap can retain said proximal catheter end on said proximal connector, said screw cap being seated on said shoulder which serves as a stop for said screw cap, said connector having a longitudinal bore for the passage of the fluid
