First Claim
1. An aseptic covering device for the connection between the tubular port of a medical liquid container and a piercing pin comprising:
- a clasp member comprising first and second substantially C-shaped body portions hingedly connected to each other and further including latching means at opposing ends thereof;
said clasp member being constructed and arranged for the pivotal enclosure of said connection between said medical liquid container and said piercing pin;
a plurality of absorbent sponge members containing an antiseptic solution disposed within each of said substantially C-shaped portions constructed and arranged for asepticizing the connection between said tubular port and said piercing pin;
a coaxial tubular end port extending distally from said clasp member and having helically arranged threading disposed thereon; and
lock nut means coaxially disposed about said tubular port member, constructed and arranged for threaded engagement with said threading means on said tubular end port of said clasp member so as to fixedly attach said tubular port to said clasp member and said piercing pin.

Abstract
A connecting device for medical liquid administration sets, particularly for use in continuous ambulatory peritoneal dialysis comprises a tubular port extending from a medical liquid container. The tubular port has a pierceable diaphragm positioned within and sealing the same. A hollow tubular piercing pin having a sharpened tip is used for penetrating the pierceable diaphragm. A length of flexible tubing extends from the piercing pin and is connected to a catheter positioned in the peritoneum of the patient once the piercing pin and port are connected. A locking mechanism is utilized for selectively retaining the piercing pin within the tubular port following insertion, and for asepticizing the connection.

11. An aseptic covering device for the connection between the tubular port of a medical liquid container and a piercing pin comprising:
-
a clasp member comprising first and second substantially C-shaped body portions hingedly connected to each other and further including latching means at opposing ends thereof;
said clasp members being constructed and arranged for the pivotal enclosure of said connection between said medical liquid container and said piercing pin;a plurality of absorbent sponge members containing an antiseptic solution disposed within each of said substantially C-shaped portions constructed and arranged for asepticizing the connection between said tubular port and said piercing pin; a first semicircular flange member coaxially extending from the distal end of said first substantially C-shaped body portion; a second semicircular flange member of substantially the same size as said first semicircular flange member and coaxially extending from the distal end of said second substantially C-shaped body portion; said first and second semicircular flange members being constructed and arranged to meet upon closure of said substantially C-shaped body, thereby forming a tubular end port from said clasp member; threading means integrally formed on and extending from said first and second semicircular flange members, constructed and arranged so as to form a helical array about said tubular end port from said clasp member; and lock nut means coaxially disposed about said tubular port member, constructed and arranged for threaded engagement with said threading means on said tubular end port of said clasp member thereby fixedly attaching said tubular port to said clasp member and said piercing pin. - View Dependent Claims (12)

20. A connecting device for medical liquid containers comprising:
-
a tubular port member extending from the container; a pierceable diaphragm positioned within and sealing said tubular port member; a hollow tubular piercing pin connected at its proximal end to a length of flexible tubing and having a sharpened tip at its distal end adapted for penetration of said pierceable diaphragm member; locking means for the selective retention of said piercing pin within said tubular port member; said locking means comprising a clasp member including first and second substantially C-shaped body portions hingedly connected to each other and further including latching means at opposing ends thereof, said clasp member being constructed and arranged for the pivotal enclosure of said connecting device and fixed positioning therein; said clasp member further including a plurality of absorbent sponge members containing an antiseptic solution disposed within each of said substantially C-shaped portions constructed and arranged for asepticizing the connection between said tubular port and said piercing pin; a first semicircular flange member coaxially extending from the distal end of said first substantially C-shaped body portion; a second semicircular flange member of substantially the same size as said first semicircular flange member and coaxially extending from the distal end of said second substantially C-shaped body portion; said first and second semicircular flange members being constructed and arranged to meet upon closure of said substantially C-shaped body, thereby forming a tubular end port from said clasp member; threading means integrally formed on and extending from said first and second semicircular flange members, constructed and arranged so as to form a helical array about said tubular end port from said clasp member; and lock nut means coaxially disposed about said tubular port member, constructed and arranged for threaded engagement with said threading means on said tubular end port of said clasp member thereby fixedly attaching said tubular port to said clasp member and said piercing pin.

21. A method of aseptically sealing the connection between a piercing pin and the tubular port of a medical liquid container with a clasp member having a plurality of sponge members therein, saturated with antiseptic solution, said clasp member comprising:
- a first semicircular flange member coaxially extending from the distal end of said first substantially C-shaped body portion, a second semicircular flange member of substantially the same size as said first semicircular flange member and coaxially extending from the distal end of said second substantially C-shaped body portion, said first and second semicircular flange members being constructed and arranged to meet upon closure of said substantially C-shaped body, thereby forming a tubular end port from said clasp member, threading means integrally formed on and extending from said first and second semicircular flanges, constructed and arranged to as to form a helical array about said tubular end port from said clasp member, and locknut means coaxially disposed about said tubular port member, constructed and arranged for threaded engagement with said threading means on said tubular end port of said clasp member for fixed attachment of said tubular port to said clasp member and said piercing pin, comprising the steps of;
inserting said pin into said port; piercing the diaphragm of said port with said pin; enclosing the assembled port and pin within said clasp mechanism having a plurality of sponge members therein, saturated with antiseptic solution; rotatably threading said lock nut means onto said threading means of said tubular end port until said lock nut means about said clasp member, thereby fixedly attaching said tubular port member to said tubular piercing pin.
- a first semicircular flange member coaxially extending from the distal end of said first substantially C-shaped body portion, a second semicircular flange member of substantially the same size as said first semicircular flange member and coaxially extending from the distal end of said second substantially C-shaped body portion, said first and second semicircular flange members being constructed and arranged to meet upon closure of said substantially C-shaped body, thereby forming a tubular end port from said clasp member, threading means integrally formed on and extending from said first and second semicircular flanges, constructed and arranged to as to form a helical array about said tubular end port from said clasp member, and locknut means coaxially disposed about said tubular port member, constructed and arranged for threaded engagement with said threading means on said tubular end port of said clasp member for fixed attachment of said tubular port to said clasp member and said piercing pin, comprising the steps of;
