Definitions

  • the invention relates to a valve arrangement of the type corresponding to the preamble of claim 1.
  • Valve arrangements of this type are used in medical technology, for example to optionally supply fluid media to body cavities during operations or to suction off such or also tissue parts.
  • Valve arrangements of this type have connections on the primary side for in each case one feed or flushing line and one suction line. These connections can optionally be brought into fluid connection with at least one connection on the secondary side.
  • connections on the secondary side for this purpose, in the prior art either so-called trumpet valves, in which a separate actuating member is provided for each primary-side connection, or known 3-way valves, in which, depending on the position of the actuating member, one or the other primary-side connection is fluidly connected to the secondary-side connection becomes.
  • trumpet valves A disadvantage of the trumpet valves is that the correct actuation requires an increased concentration from the user, since the functions of the individual actuating elements can easily be confused.
  • a disadvantage of the 3-way valves is that a one-handed rotary actuation of the actuating member is difficult, and is often impossible in the case of stiffness.
  • the invention is therefore based on the object of creating a valve arrangement, the manageability and operational reliability of which is improved compared to the valve arrangements known from the prior art. This object is achieved by the invention reproduced in claim 1.
  • valve arrangement comprises an actuating member which can be actuated by overcoming a restoring force via an actuation path and is designed such that the various switching states are brought about when actuated via the actuation path, ensures that when the valve arrangement is not actuated, the same structurally predetermined switching state always occurs - mostly the interruption of the primary connections from the secondary connections. If the valve arrangement is now actuated by the user, the same switching state is always brought about after overcoming a first actuation path, and the same further switching state is always brought about after overcoming a second actuation path.
  • valve arrangement such that the connection of the lines between the supply line and the suction line, on the one hand, from the line (s) leading to the body cavity (s), on the other hand, is particularly advantageous if the actuating member is not actuated since Valve is not undesirably affected on the patient's body.
  • valve arrangement The operability of the valve arrangement is considerably simplified if it is designed such that between the connection of the supply line with a line leading to a body cavity and an actuation position causing the interruptions of the connection is provided for the connection between the suction line with an actuation position causing a body-leading line.
  • this preferred embodiment of the valve arrangement according to the invention is distinguished by the fact that there is a “dead” actuation path between the flushing and the suction actuation of the valve arrangement, in which no primary-side connection is fluidly connected to a secondary-side connection The risk of incorrect operation of the valve is once again reduced and its handling is easier since the correct use requires less precise actuation of the valve by the operating personnel.
  • valve arrangement is again more reliable when each of the actuating positions corresponding to a switching state is characterized by a predetermined restoring force of the actuating element.
  • the rinsing process can be effected while overcoming a first, low restoring force, " on the other hand, overcoming a higher restoring force may be necessary in order to switch over to the suction switching state.
  • the valve arrangement is particularly ergonomic when it includes a handle.
  • the actuating member is then preferably an actuating lever which is pivotably mounted about an axis.
  • a structural design of the valve arrangement is particularly preferred, in which a valve insert inserted into the handle is provided.
  • valve insert is arranged interchangeably in the handle.
  • the valve arrangement is then particularly easy to clean after use.
  • valve insert is structurally preferably effected in that the valve insert is provided in a receiving bore which runs transversely to the supply and discharge line and communicates with it. If the latter - as is particularly preferred - is designed as a blind hole drilled in the handle on the side of the actuating lever, the valve insert can be inserted from the outside in a particularly simple manner by pushing it into the receiving bore and correspondingly removed in reverse.
  • valve arrangement can be actuated with a corresponding structural design of the valve insert by moving the actuating lever until its side facing the handle presses the valve insert into the blind hole. Complex articulations of the valve insert for its actuation are thus avoided.
  • the valve insert preferably has two parts which can be displaced relative to one another. These can be designed such that they engage telescopically. It is then preferably provided between the two parts, a first compression spring causing the same to move apart. The valve insert is then, as is particularly preferred, supported by a second compression spring on the bottom of the blind hole.
  • a third spring element is provided on the valve insert, which acts between the bottom of the blind hole and the second part of the valve insert. If the third spring element is designed in such a way that it is activated after about half the actuation path of the second part, three restoring forces have to be overcome when the actuation lever is actuated:
  • the valve insert is then preferably designed so that the suction is activated while overcoming the first restoring force, the valve is completely closed while overcoming the second restoring force and overcoming the third restoring force finally brings about the flushing process.
  • the valve insert is particularly easy to disassemble and replace if it is designed to be self-retaining in the blind hole. Additional fasteners can then be dispensed with.
  • the Self-holding can be brought about, for example, by the individual parts of the valve insert which surround radially surrounding sealing rings.
  • valve insert - as preferred - is intended for single use, the risk of infection for the patient is particularly low since a new, sterile insert can be used for each application.
  • FIG. 1 schematically - a valve assembly according to the invention in a side view
  • Fig. 6 the same view as in Figs. 2 to 5, but without the valve insert and Fig. 7 - a detail - an enlarged view of the sole area of the receiving bore with the valve insert partially inserted.
  • the valve assembly designated as a whole by 100 comprises a handle 1, on the underside 2 of which a connection piece 3 is provided for connecting a suction line (not shown in the drawing) and a connection piece 4 for connecting a supply line (also not shown in the drawing).
  • the suction line is symbolized in the drawing by arrows P, the supply line by arrows PP.
  • the connector 3 is fluidly connected to a suction channel 5 provided within the handle 1 and the connector 4 is fluidly connected to a supply channel 6 also provided within the handle 1. Both the suction and the supply channel are passed separately from one another through the entire handle 1 and open at the head of the handle into connecting means, not shown, for lines which likewise lead to a patient's body cavity and which are also not shown.
  • an actuating member 8 designed as an actuating lever 7 is mounted so as to be pivotable about a pivot axis A. It serves for the optional actuation of a valve insert 9, which projects beyond the outer contours of the handle 1 in its relieved position, by an actuation path B, as is to be symbolized by the position of the actuation lever 7 shown in dashed lines in FIG. 1.
  • the valve insert 9 which rests in a blind bore 10, comprises a first part 11 and a second part 12.
  • the first part 11 has a central bore 13, as shown in the drawing, closed towards the actuating lever, into which the second part 12 has a cross section adapted extension 14 engages.
  • both a first compression spring 15, which is accommodated in a space located within the bore between the extension and the bore end, and a second compression spring 16, which are located between the second Part 12 and the sole 17 of the blind bore 10 acts relaxed.
  • the parts 11, 12 of the valve insert are designed such that on the one hand they can still be displaced relative to one another from this position, and on the other hand completely close both the suction channel 5 and the feed channel 6.
  • the second compression spring 16 When the valve arrangement is actuated while overcoming a first restoring force, which is shown in FIG. 3, the second compression spring 16 is first compressed due to the preselected spring constants, so that a between the front end 18 of the first part 11 and a facing annular surface 19 of the second Part 12 remaining free space 20 is shifted into the position of the suction channel 5 and releases it.
  • the outer circumference of the first part 11 of the valve insert 9 is designed such that the cross section of the feed channel 6 remains completely closed in this position.
  • the sole 17 of the blind hole 10 has an extension 21 which is conical in longitudinal section and protrudes into the blind hole 10 over a length which corresponds approximately to the radius of the suction channel 5.
  • the end of the part 12 of the valve insert 9 facing the extension 21, as can be seen in FIG. 7, is equipped with a core 22 which has a longitudinal slot 23.
  • the core, the longitudinal slots and the extension are matched to one another in such a way that the part 12 can be moved up to the sole 17 of the blind bore 10 by widening the longitudinal slot 23, which require a spring-elastic bending of the parts of the core 22.
  • This switch position is shown in Fig. 5.
  • both the suction duct 5 and the feed duct 6 are completely closed by the valve insert 9. Due to the compression of the first compression spring 15, the two parts 11, 12 of the valve insert 9 are completely pushed into one another, so that the free space 20 according to FIGS. 2 and 3 no longer exists. 4 therefore characterizes a switching position between the suction and rinsing position of the valve insert, in which both channels 5 and 6 are closed.
  • the second compression spring 16 has a smaller spring constant than the compression spring 15, but the latter is smaller than the sum of the spring forces of the second compression spring and the third spring element 25 formed by the extension 21 and the core 22.
