Abstract
UNIVERSAL PIERCING PIN
Abstract of the Disclosure A universal piercing pin for vented and unvented I.V. administration sets has a hollow spike member with fluid passages spaced apart around the external surface of the spike member. In vented sets, the tip of the spike member and an entry port to a fluid passage are inserted sufficiently through the seal of a rigid solution container to allow fluid to pass out of the container through the spike member and air to pass into the container through the fluid passage. A
hydrophobic filter, positioned in a fluid passage, prevents the passage of liquid but allows the passage of air into the container. In unvented sets, only a portion of the spike member is inserted through the seal of a flexible I.V. container which allows fluid to pass out of the flexible container through the spike member without allowing air to flow into the flexible container through the fluid passages.

Description
The present invention relates to I.V.
administration systems, and more particularl~, to piercing pins usable in both vented and unvented I.V.
administration systems using rigid and fle~ le containers respectively.
Liquids, such as amino acids, blood, de~trose, electrolytes, and saline are usually adrninistered to patients over a prolonged period of time through an I.V.
administration set. Generally, these I.~J.
administration sets employ a rigi~ container such as a glass bottle or a fle~ible container such as a plastic bag to store the liquid which is to be -fed intravenously to the patient. An example of such sets is an I.V.
administration set marketed under the trade name Venoset, by Abbott Laboratories. Similar systems are disclosed in U.S. Patent 3,886,937 to Bobo, et al.; and U.S. Patent 4,105,029 to Virag.
One of the problems with I.V. administration sets employing rigid containers is that in order to dispense liquids from a rigid container, air must be drawn into the container as liquid flows from the container. Accordingly, venting mechanisms are empLoye~
which allow for the entrance of air into the rigid liquid container as the liquid is being withdrawn. ~he conventional means of venting a rigid container is through a vented piercing pin whicih is inserted through the puncturable closure normally used to seal the rigid medical liquid container.
To avoid the necessity of venting the container of I.V. fluid and to reduce the cost of the system, a recent innovation in I.V. administration systems has been the use of blow-molded, collapsible, fle~ible -1- r~ ~
~ ~L ~3¢~
containers to dispense lir~ui-ls. These containers lo not require venting, as the sides of the container col'apse as the liquid supply is depleted. ~n eY.am~le of such containers may be found in U.S. Patent ~o. 4,2~,409 assigned to Abbott Laboratories.
A problem has arisen, nowever, in tihe manufacture of equipment sets in ~eneral and in the manufacture of piercing pins in partlcular.
Specifically, different piercins pins must be used for vented systems employing rigid con'ainers and unvented systems whicn employ flexible containers. It has been found that on some occasions, vented piercins pins have been used with flexible containers which results in the risk that air may be passed th~ough the I~V.
administration system to the patient. Converselv, in some instances, unvented piercing pins have been used with rigid containers, thereby rendering the vented system employing the rigid container inoperative because air is not allowed to flow into the container in place of dispensed fluid. One attempt to solve the venting problem for rigid containers may be seen in U.S. Patent NoO 3,662,752 to Yokoyama. The close proximity of the openings for air and fluid in the device disclosed in this patent render it unusable with flexible containers as the design of the piercing pin between its tip and the air vent would not allow it to be re~ained in tne closure of a flexible container.
It is, therefore, an advantage o~ the present invention to provide a universal piercing pin which ma~
be used in both vented and unvented l.V. administration systems. It is an additional advantage of the present invention to provide a piercing pin in which the ventiny of an I.V. administration system may be selectivel~
actuated.

~,~,'t~ ti~.3 According to the present lnventlon there i5 provided a piercing pin for providlng fluid communication with tne interior of a rlgicl or flexible liquid container, the pin having a substantially longitudinal spike member adapted for the flow of liquid having a piercing tip at one end. A lumen extends through the splke member having a first and second opening at either end of the lumerl, the first opening being operatively positioned proximate the piercing tip and the second opening being spaced from the piercing tip~ At least one fluid passage is positioned exteriorly of the spike member and having a first port and a second port, the first port being spaced inwardly from the first lumen opening. At least one of the fluid passage members is adapted for the flow of air. A hydrophobic membrane is operatively positioned within the fluid passage and is adapted for the flow of air. When the piercing pin is used with a rigid liquid container, the first port of the fluid passage is positioned in fluid communication with the inside of the rigid container and the spike member provides a path for the flow of liquid out of the rigid liquid container through the first opening, the lumen and the second opening, and the fluid passage provides a path for the flow of air into the rigid liquid container through the second port, the fluid passage and the first port.
When the piercing pin is used with a flexible container the first port of the air passage is positioned out of fluid communication with the inside of the flexible liquid container and the spike member provides a path for the flow of liquid out of the flexible liquid container through the first opening, the lumen and the second opening.
In a specific embodiment of the invention the hydrophobic membrane is positioned in the second port of the fluid passage.
More specifically, there may be provided a plurality of fluid passagesO
A rubber reseal may be operatively positioned in a second port of one fluid passage and a hydrophobic member is positioned in another second port of the fluid passage.

Detailed Description of the Preferred ~mbodiment While this invention is susceptible of man~
embodiments in many different forms, there is shol/n in the drawings and will be herein described the preferred embodiment, with the unders-tanding that the preferrec~
embodiment illustrated hereitl is an e~emplificati~ll of the principles of the invention and is not intended to limit the invention to the preferred eml~odiment illustrated.
As best seen in FIGURE 1 of the drai~ings, vented I.V. administration set generally L0 has a rigid medical liquid container 11 with a resilient, resealable, penetrable sealing member 12 at container opening 13. Extending through resilient, penetrable sealing member 12 is the device of this invention, piercing pin generally 30, which in this case has a drip ~ ¢~3 chamber 16 attached theret:o. E,Yten~irlg frorr, dri~
chamber 16 is a l.ength of ~lexi~le tuhing 17, upon lhich is affixed a roller clamp 18, and an on/ofE sli-le clarnp 27 for contr~Lli.ng the flow of medical liqui~i 19 frorn container 11. At the opposite end of flexibLe tubing 17 is a hypodermic needle 20, which is inserted into t~e arm of a patient Eor the administration of medical liquid 19~
As further seen in FI~-U~E 2 of the dra~ gs, an unvented I.V. administration system, generally 21, ihas a collapsible medical liquid container 22 with a resilient rubber reseal 23 affi~ed at container end 24. ~xtendin~
through resilient rubber reseal 23 is the device of this invention piercing pin 30. Extending from piercina pin 25 is a drip chamher 25 which may be used to count the number of drops per minute and thereby determine the rate of flow of medical liquid 19 from container 22.
Extending from drip chamber 26 is a length of fle~ible tubing 17, on whicll is mounted a roller clamp 1~, an on/off slide clamp 27, and a hypodermic syringe 20.
The construction of the improved universal piercing pin of this invention is best seen in FIGURES 3 and 4. Specifically, the device of this invention consists of a spike member 32 having a substantially longitudinal lumen 36 running therethrough. The snike member terminates at a piercing tip 34 which is adaptecl for penetration oE a punc~urable sealing member roun~ in either ri~3id container 11 (FIGURE 1) or Elexible container 22 (FIGUR~ 2). The ll~men 3~ runnin~3 throuah spike member 32 begins at first opening 40 and ends at second opening 48. Supportinc3 spike member 32 is a oase flange 52. Furtner support for spike member 32 is provided by ring 54 which, in the preferred embodiment, is shown as having a substantially triangular cross section. Located on the e~ternal sur~ace oE piercing _. 5 _ , ....
pin 32 are fluid passages 3B which are ~orme~1 b~ the presence of an oversllroud 50 formed aroun~l spike~ mernber 32. The fluid passages 38 exten~3 from first port ~ to second port 43. Shown positioned at the second port 43 of one flui~ passage 38 is hy~lrophobic membrane ~4.
Shown positioned in another fluid passage 3~ is an optional rubber reseal 45. Overshroud 50 is maintained in place by frictional interfitment 51 over spi~.e ~ember 32.
Operation The operation of the universal piercing pin 30 of this invention is best seen in FIGURES 5 and 6.
In FIGURE 5, pin 30 is sho~n as protrudin?
through resilient, resealable, penetaDle sealing member 12 to point 45. The insertion o-F piercing pin 30 into resilient, resealable, penetrable sealing memDer 12 to point 45 causes lumen 36 to be in fluid communica~ion with the liquid contained within the I.V. container, thus allo~ing the liquid to pass through fluid passage 36 from first ~pening 40 to second opening 48. As the fluid flows out of the container, air must replace .he displaced fluid. This air is supplied to the container by first passing tllrough hydrop11obic me~brane 44 in port 43, then through passage 3~ aild finall~ throu(3h secon-l port 42 into the container.
In FIGUR~ Z, it is shown that the same improved piercing pin 30 used with the port o~ a rigi~ container (FIGURE 5) may also he used in the por-t of a fle~i~le container. Specifically, piercing pin 30 is inserted through protective cap 7~ so that opening 40 is in --lui~
communication with the liquid witnin the fle~ible container. Rather than being inserted through resilient rubber reseal 23 to point 45 as ~ith the rigi,-l container (FIGUR~ 5), improved piercing pin 30 is inserted o~
partway through reseal 23 so as to Leave first port 42 out~ide the container of I.V. solution. In this ~ay, air does not pass throu~h hydrophobic membrane 44 to the inside oL the container, but I.V. flui~ may pass from the interior of the flexible container through first opening 40, lumen 36 and out second openin~ 4~ in~o the l.V. administration system (not above).
The preferred material for fabrication of the improved universal piercing pin 30 is rigid polyvinylchloride. However, other plastic materials such as polycarbonate, ~BS, or styrene could be utilized. Inserted within second port 43 is a hydrophobic membrane 44 as previously stated.
Optionally, inserted within one fluid passage 38 is rubber reseal 46 which allows for the temporary insertion oE a cannula or hypodermic needle to add medicament to or extract samples from the I.V.
ad~inistration system.
It will tnus be seen that through the present invention there is now provided a improved universal piercing pin for both vented and nonvented I.V.
administration sets wherein rapid connection and disconnection may be made with a source of I.V. fluid.
The improved universal piercing pin of this invention can be readily molded and fabricated at little cost so as not to appreciably add to the cost of a complete I.~v7.
administration set~
