Definitions

  • the invention relates to a patient safety connector, in particular in the form of a Luer connector for connecting medical hose lines or other medical components.
  • Patient connectors are connection elements that are arranged at the end on infusion devices, connection lines or other medical components. These connectors are used to establish connections to patient-side mating connectors that are attached, for example, to intravenous cannulas, connecting lines or tap banks.
  • the one connector which is referred to as a female connector
  • the other connector which is referred to as a male connector
  • Radial lugs of the female connector engage in the threaded sleeve.
  • the invention has for its object to provide a patient safety connector with which it is ensured that the connector connection can be released again with little effort.
  • the connector body on which the connecting part and the screw part is provided, has a rotatable grip part which is coupled to the connector body by an overload coupling.
  • the handle part is used to grip by hand for the purpose of tightening and loosening.
  • the handle part takes the connector body with it via the overload coupling, so that it is rotated in relation to the mating connector and the Luer lock connection is tightened.
  • the limit torque of the overload clutch is reached, the handle part can be turned further, but it then no longer takes the connector body with it. This prevents the connection from being over-tightened.
  • the connection is easy and can be released at any time without any tools.
  • the overload clutch only acts in the direction of rotation that corresponds to the tightening of the screw part.
  • the opposite direction i.e. in the direction of rotation, which corresponds to the loosening of the screw part, it has no torque limitation. This ensures that when tightening the connector connection Torque is limited, but such a limitation does not occur when loosening. This ensures that turning up is possible in every case.
  • the connector body has sawtooth-shaped locking teeth and resilient tongues are provided on the handle part, which slide over the locking teeth. This enables a simple and inexpensive implementation of the security connector. Another advantage is that the overload clutch generates clicking noises when the limit torque is exceeded and signals the user clearly that the connection has been tightened to the required torque.
  • the invention prevents not only excessive tightening of the connection, but also insufficient tightening, which could lead to unintentional loosening, is prevented if the user tightens the connection until the overload clutch slips.
  • the invention is generally applicable to connectors with a screw part.
  • This screw part can be an internal thread or an external thread or, as in the case of female Luer lock connectors, approaches that protrude radially from a sleeve. In other words: it does not matter whether the connector or the mating connector is equipped with the overload coupling.
  • the handle part should extend so far over the length of the respective connector that the user is not tempted to directly attack the connector body with his hand. Rather, it should only grip the connector on the handle part. A preferred embodiment of the invention is explained in more detail below with reference to the drawings.
  • FIG. 2 shows a longitudinal section through the safety connector according to FIG. 1,
  • Fig. 5 is a section along the line V-V of Fig. 2, and
  • Fig. 6 is an exploded view of the security connector.
  • the patient safety connector shown is a male Luer connector with a V-shaped elongated connector body 10, which has a tube extension 11 at one end for pulling on the end of a tube 12 and an outer cone 13 at the opposite end.
  • the tube extension 11 and the outer cone 13 are arranged coaxially and connected by a straight longitudinal channel 14.
  • the outer cone 13 is surrounded by a screw 15.
  • This is a union nut 16 with threads 17 arranged on the inside.
  • a union tube 18 surrounds part of the length of the tube extension 11.
  • the connector body Approximately in the middle of its length, the connector body has an outer circumferential groove 19 and adjoining it a radially standing ring 20 on.
  • the groove 19 and the ring 20 serve to hold a grip part 21 axially, which is pushed onto the connector body from the rear end (from the tubular extension 18).
  • the grip part 21 consists of a tubular ring part 22 which has an inner annular groove 23 and an annular projection 24 adjoining it.
  • the annular groove 23 receives the projection 20 of the connector body and the projection 24 dips into the annular groove 19 of the connector body. In this way, the ring part 22 is rotatably but axially immovably fixed to the connector body 10.
  • the handle part 21 has at the rear end an annular end wall 25, from which a plurality of resilient tongues 26 project axially parallel to the front. These resilient tongues 26 run in the axial direction of the connector body, but are slightly inclined, and they each have a tip 27 at their front ends.
  • a rearward-facing shoulder 28 is provided, in which a plurality of sawtooth-shaped locking teeth 29 are formed.
  • the tips 27 of the resilient tongues 26 engage in the tooth gaps between the ratchet teeth 29, as is shown in FIG. 5.
  • the resilient tongues 26 and the locking teeth 29 form an overload clutch 30.
  • This overload clutch is shown in engagement in FIG. 5. If the tubular handle part 21 is rotated in the tightening direction, which is indicated in FIG. 5 by the arrow 31, then the tongues 26 move in the direction of the arrow 32, pressing against the oblique flanks of the saw teeth 29 and thereby rotating the connector body 10 as well. When the limit torque is reached, the resilient tongues 26 bend, as a result of which the tips 27 slide over the locking teeth 29, so that there is no rotational entrainment more done. This prevents excessive tightening of the screw connection.
  • the handle part 21 When loosening the screw connection, the handle part 21 is rotated in the loosening direction against the arrow 31 in FIG. 5, the tips 27 of the resilient tongues 26 being pressed against the steep flanks of the saw teeth. Since the tongues 26 are subjected to pressure and are not bent, they take the connector body 10 in this direction without torque limitation.
  • a protective cap 33 is provided, which is attached to the front end of the union nut 16 and sealingly engages the outer cone 13. This protective cap 33 can be removed in order to be able to connect the mating connector.
  • the grip part 21 covers the connector body 10 over a substantial part of its length. It has a cylindrical outer surface with a corrugation 34 to allow firm gripping by hand.
  • the safety connector consists of only two parts, namely the connector body 10 and the handle part 21 sitting on it.

Abstract

L'invention concerne un connecteur de sécurité comprenant un corps (10) avec une partie de raccordement (13) et une partie filetée (15). Pour empêcher un serrage excessif avec le connecteur correspondant, une partie de préhension (21) rotative est disposée sur le corps (10), cette partie étant raccordée au corps par l'intermédiaire d'un accouplement de surcharge (30), ce qui permet de limiter le couple de vissage de sorte qu'il soit possible de desserrer les éléments à tout moment.
