Abstract

Claims (33)

1 . An apparatus for accessing contents of a medicinal container, the apparatus comprising:

a fluid exchange connector comprising a flange to aid in coupling the apparatus with an exchange device or instrument used in extracting fluid from or injecting fluid into the medicinal container;

a housing comprising an engagement assembly configured to be coupled to the medicinal container, wherein the engagement assembly comprises at least one of a cap connector, an adhesive, or tape;

an insertion assembly comprising:

a piercing member having an extractor aperture;

an insertion member comprising the piercing member at a distal end of the insertion member;

an insertion member channel having a proximal end; and

a locking ring configured to engage with a protrusion at the proximal end of the insertion member channel,

wherein the insertion member is configured to slide along the insertion member channel, and the piercing member is configured to pierce a septum of the medicinal container;

an extractor channel configured to connect the extractor aperture to the fluid connector; and

a regulator channel configured to regulate pressure within the medicinal container while extracting fluid from or injecting fluid into the medical container;

wherein the engagement assembly is configured to prevent the insertion member from sliding along the insertion member channel until the apparatus is coupled to the medicinal container;

wherein the engagement assembly engages the locking ring when the insertion member is moved into a fully inserted position; and

wherein the engagement assembly is configured to prevent the piercing member from piercing the septum of the medicinal container until the apparatus is coupled to the medicinal container.

2 . The apparatus of claim 1 , wherein the extractor channel runs parallel to the insertion assembly.

3 . The apparatus of claim 1 , configured such that the piercing member pierces the septum of the medicinal container while the insertion assembly slides along the insertion member channel.

4 . The apparatus of claim 1 , wherein the insertion assembly is maintained parallel to the insertion member channel by the engagement assembly.

5 . The apparatus of claim 1 , configured such that sliding the insertion assembly along the insertion member channel towards the septum of the medicinal container moves the insertion assembly into the fully inserted position.

6 . The apparatus of claim 5 , wherein at least a portion of the piercing member is inside the medicinal container when the insertion assembly is in the fully inserted position.

7 . The apparatus of claim 5 , wherein the engagement assembly engages the insertion assembly when the insertion assembly is in the fully inserted position.

8 . The apparatus of claim 5 , wherein one or more arms of the engagement assembly engage the insertion assembly when the insertion assembly is in the fully inserted position.

9 . The apparatus of claim 8 , wherein the one or more arms of the engagement assembly are in a second position when the insertion assembly is in the fully inserted position.

10 . The apparatus of claim 5 , wherein the engagement assembly keeps the piercing member inside the medicinal container when the insertion assembly is in the fully inserted position.

11 . The apparatus of claim 5 , wherein the engagement assembly prevents the insertion assembly from sliding along the insertion member channel away from the septum of the medicinal container when the insertion assembly is in the fully inserted position.

12 . The apparatus of claim 5 , wherein apparatus produces a snap sound when the insertion assembly is moved into the fully inserted position.

13 . The apparatus of claim 1 , wherein the engagement assembly comprises one or more arms, and wherein the one or more arms are configured to move between a first position and a second position.

14 . The apparatus of claim 13 , wherein the one or more arms are further configured to engage the insertion assembly.

15 . The apparatus of claim 13 , wherein the one or more arms are further configured to disengage the insertion assembly.

16 . The apparatus of claim 13 , wherein the one or more arms engage the insertion assembly before the apparatus is coupled to the medicinal container.

17 . The apparatus of claim 13 , wherein the one or more arms are in the first position before the apparatus is coupled to the medicinal container.

18 . The apparatus of claim 13 , wherein the one or more arms move from the first position to the second position as the apparatus is coupled to the medicinal container.

19 . The apparatus of claim 13 , wherein the one or more arms are in the second position when the apparatus is coupled to the medicinal container.

20 . The apparatus of claim 13 , wherein the one or more arms disengage the insertion assembly as the one or more arms move from the first position to the second position.
