Definitions

  • peritoneal dialysis and particularly continuous ambulatory peritoneal dialysis there is a great need to maintain aseptic conditions during the course of the procedure, during which peritoneal dialysis solution is passed into the peritoneal cavity and thereafter removed from the peritoneal cavity.
  • Typical peritoneal dialysis procedures require disconnection and reconnection of a connector which terminates a set communicating with the interior of the peritoneal catheter with other connectors on various bags or other containers of peritoneal dialysis solution. The slightest touch of a critical portion of the connector with a contaminated surface is believed to create a significant risk of peritonitis to the patient.
  • Steri-Track device which has been used and which is described in an article entitled “CAPD for the Blind” from the Periodical Nephrology Nurse, March/April 1981, pp.
  • This device is a self-contained, portable device.
  • a fresh bag of dialysis solution is placed into a stationary end of a holder.
  • the protective tab of the bag is removed, and a spike is taken from the discharge bag and fitted into the grooves of a movable plate.
  • the patient now manipulates the sliding plate toward the bag, with the result that the spike will plunge into the port of the bag with alleged 98 percent probability.
  • the apparatus shown uses a pair of shaped slots into which a movable retention means for a connector fits, to permit its motion between a first and a second position with the connection of a connector carried therein being made with a second connector in the first position and a third connector in the second position.
  • the device of this invention can be used for the precise, mechanical connection of connectors which fit together in screw-threaded or other rotary locking relationship.
  • This invention relates to apparatus for removing a first connector from a second connector and reconnecting the first connector with a third connector, which comprises first, second and third retention means for respectively carrying first, second and third connectors.
  • Platform means are provided for carrying the first, second and third retention means in typically fixed spatial relationship with each other.
  • First slot means * are provided to the platform means for permitting controlled movement of the first retention means along with the first slot means between a first position permitting disconnection between first and second connectors, and a second position permitting connection between first and third connectors, when the first, second and third connectors are respectively carried in the first, second and third retention means.
  • a first pin member is carried by the first retention means and is slidable in the slot means.
  • a second slot is defined in the first retention means, and a second stationary pin member is carried by the platform means in a position to be slidable in the second slot.
  • the first retention means carries rotatable barrel means defining an aperture for receiving a first connector.
  • the purpose of this is to permit rotational connection and disconnection between the first connector and other connectors, specifically the second and third connectors.
  • the barrel means may define an axis of rotation parallel to the axis of the second slot of the first retention means which, in turn, is typically parallel to the axis of the first retention means itself.
  • the aperture of the barrel means is also desirable for the aperture of the barrel means to be proportioned and adapted to prevent relative rotation of a connector carried in it with the barrel itself, so that the barrel means can be rotated with positive rotational control of the connector. Typically this may be accomplished by making the connector-gripping portion of the aperture of noncircular cross section and of a shape to grip the specific periphery of the desired connector, to prevent rotation.
  • the aperture of the barrel may constitute a bore extending the length thereof, plus a longitudinal slot which communicates between the bore and the exterior, so that the connector may be inserted laterally into the barrel means, and any tubing to which the connector is attached may also be inserted therein through the slot.
  • the second stationary pin member carried on the platform means to define an elongated head overlying the second slot of the first retention means, to lock the first retention means onto
  • the platform means may be proportioned to permit removal of the first retention means from the platform means when the head is in a position parallel to the second slot.
  • the first retention means may be removable from the platform means, with the elongated head passing through the second slot for separation of the components.
  • the first slot means may define a hooked section spaced from sections of the first slot which permit the movement between the first and second positions discussed above.
  • the hooked section permits movement of the first retention means into the position of parallel relation with the elongated head, permitting separation of the components.
  • the first slot means also may define a pair of angularly related straight sections, connected by an arcuate section, to permit movement of the first retention means between the first and second positions.
  • Figure 1 is a perspective view of one embodiment of the apparatus of this invention with the first retention means being shown in its first position.
  • Figure 2 is a perspective view of the apparatus of Figure 1 with the first retention means shown in a position intermediate between the first and second positions, with a portion of the set held therein broken away.
  • Figure 3 is a plan view of the apparatus of Figure 1 - 6 -
  • Figure 4 is a plan view of the apparatus of the previous drawings showing its mode of disassembly.
  • Figure 5 is a sectional view taken along line 5-5 of Figure 3.
  • Figure 6 is a sectional view taken along line 6-6 of Figure 3.
  • Figure 7 is a sectional view taken along line 7-7 of Figure 3.
  • apparatus 10 of this invention is for providing reliable mechanical means for removing a connection between a conventional CAPD set 12, for example, which connects to a peritoneal catheter of a patient at one end, and a first dialysis solution bag 14, and for providing reliable mechanical connection between set 12 and a second peritoneal dialysis solution bag 15.
  • the specific design of connectors utilized in the bags and sets for connection and disconnection may be in accordance with U.S. Patent No. 4,294,250, for example.
  • Bag 15 may be sealed with a break-away member 20 for access to the contents of the bag in accordance with U.S. Patent No. 4,340,049, for example.
  • the apparatus comprises a first retention means 22, typically for holding connector 18 of set 12.
  • Second and third retention members 24, 26 define slots 28, each of which are proportioned to hold a connector 16, of one of the dialysis solution bags 14, 15.
  • Slots 28 may be of trapezoidal shape in plan view (figs. 3 and 4), so that narrow rear ends 29 of slots 28 can grip the - 7 -
  • Each of retention means 22, 24, 26 are carried on platform 30, which may be a plastic plate or the like.
  • Platform 30 defines a first slot 32 of the shape indicated in Figure 4, for permitting controlled movement of first retention means 22 along first slot ' 32 between a first position permitting disconnection between first and second connectors 16, 18, as shown in Figure 1, and a second position permitting connection between first and third connectors 18, 16a_, resulting from advancement of first retention means 22 to a position where the two connectors can be locked together i.e. approximately that shown in Figure 3.
  • Pin member 34 is carried by first retention means 22 and projects in sliding relationship into slot 32, which can extend completely through platform 30 for ease of cleaning. Thus the position of the front end of first retention means 22 is controlled by the position of pin member 34 in slot 32.
  • First retention means 22 also defines a second slot 36, typically a straight slot, into which projects stationary pin 38, immovably affixed to platform means 30.
  • Stationary pin 38 carries an elongated head 40 which, in most positions of member 22 in slot 32, retains member 22 in sliding, retained relationship with platform 30. Accordingly, first retention means 22 is retained on platform 30 due to its double retention at two positions, one by the action of pin 38 in slot 36, and the other by the action of pin 34 in slot 32. This permits first retention member 22 to be precisely aligned in its first position as shown in Figure 1, so that connectors 16, 18 can be disconnected or connected together in that position. - 8 -
  • First retention means 22 can then slide along the precisely defined continuum of positions to the second position in which connector 18 can lock with connector 16a_, with pin 34 moving from one end 42 of slot 32 ( Figure 3) almost to intermediate corner 44 of slot 32, at which time the second position is achieved.
  • first retention means 22 is held in pivoting relationship with pin 38 in slot 36 for precise, angular guidance of member 22 as its pin 34 slides along slot 32, being retained in locked relation with platform 30 by elongated head 40.
  • First retention means 22 carries a block 46 defining a slot in which rotatable barrel means 48 is carried.
  • Barrel means 48 defines an aperture 50, plus an added slot 52 extending its entire length, for receiving and retaining a connector 18 as well as the length of set tubing 12 to which the connector is attached.
  • Set 12 may be placed into the rotating barrel means while connector 18 is carried within aperture 50. See Figure 7, for example.
  • aperture 50 may be proportioned to prevent relative rotation of a connector 18 held therein by being, for example, of square or rectangular cross-section, so that rotation of barrel member 48 can cause rotation of the connector. This permits locking of the screw threaded connectors together with ease, simply by grasping handle 54 and rotating while engaging the respective connector 16 (for unlocking) or 16a_ (for locking). Barrel member 48 may be held in snapfit relation in the slot 47 of post 46,
  • Bolts 53 hold post 46 onto member 22, while bolts 55 may retain each of second and third retention means 24, 26 onto platform member 30.
  • slot 32 may comprise a pair of angularly related straight sections 56, 58, connected by an arcuate section 60 to permit movement of the first retention means 22 between the first and second positions.
  • slot 32 defines a hooked section 62 which is spaced from sections of slot 32 which permit movement between the first and second positions.
  • This hooked section 62 may be present to permit movement of first retention means 22 into a position where second slot 36 is essentially parallel to the long axis of elongated head 40.
  • Elongated head 40 may then be proportioned so that member 22 may be lifted off in that position, as shown in Figure 4, for cleaning and the like, with pin 34 simply lifting out of slot 32 in that position.
  • member 22 may be replaced, with head 40 of pin 38 passing through slot 36, and pin 34 passing into hooked section 62 of slot 32. Thereafter, member 22 may be moved again so that pin 34 passes into sections 56, 58 and 60 of slot 32, in which position head 40 is in angular relation to slot 36, thus locking first retention means 22 onto platform member 30.
  • a CAPD patient who is blind or physically debilitated may have a transfer set 12 connected to his peritoneal catheter, terminating in a connector 18, which, in turn, is connected to a connector 16 of an empty bag 14.
  • the patient has the peritoneal dialysis solution in is peritoneal cavity, and he seeks to make an exchange.
  • an outer protector may be applied to the joined connectors 16a_, 18 of the type shown in U.S. Patent No.4,340,052, to further protect the connection.
