Medical Device Needle Receiving Port

Abstract

A medical device needle receiving port configured to stop a needle's penetration without physically engaging the needle's tip thereby reducing the likelihood of tip damage. The port preferably incorporates a particulate chamber for collecting particulates larger then a fluid outlet dimension.

1 - 11 . (canceled) 
   
   
       12 . A needle port, comprising:
 a needle entrance including an entrance opening that defines a width and a length that is greater than the width;   a needle stop including a converging wall and a stop hole that is smaller than the width of the entrance opening; and   a septum located between the entrance opening and the needle stop hole.   
   
   
       13 . A needle port as claimed in  claim 12 , wherein the entrance opening comprises a slot. 
   
   
       14 . A needle port as claimed in  claim 12 , wherein the needle entrance includes a converging wall that terminates at the entrance opening. 
   
   
       15 . A needle port as claimed in  claim 12 , wherein the stop hole defines a diameter that is less than the width of the entrance opening. 
   
   
       16 . A needle port as claimed in  claim 12 , wherein the needle stop converging wall terminates at the stop hole. 
   
   
       17 . A needle port as claimed in  claim 12 , wherein the needle stop converging wall defines a funnel-shaped recess. 
   
   
       18 . A needle port as claimed in  claim 12 , wherein a portion of the septum is located within the needle stop. 
   
   
       19 . A needle port as claimed in  claim 12 , wherein
 the needle stop includes a recess; and   the stop hole is located between recess and the converging wall.   
   
   
       20 . A needle port as claimed in  claim 19 , wherein the recess defines a particulate chamber. 
   
   
       21 . A needle port for use with a needle having a pointed distal tip and a bevel where the needle diminishes in size down to the pointed distal tip, the needle port comprising:
 a needle entrance including an entrance opening;   a surface located in spaced relation to and aligned with the entrance opening; and   means, located between the entrance opening and the surface, for preventing the pointed distal tip of the needle from contacting the surface by engaging the needle bevel after the needle passed through the entrance opening.   
   
   
       22 . A needle port as claimed in  claim 21 , further comprising:
 a septum located between the entrance opening and the means for preventing.   
   
   
       23 . A needle port as claimed in  claim 21 , wherein the entrance opening defines a width and a length that is greater than the width. 
   
   
       24 . A needle port as claimed in  claim 21 , wherein the entrance opening comprises a slot. 
   
   
       25 . A needle port as claimed in  claim 21 , wherein the needle entrance includes a converging wall that terminates at the entrance opening. 
   
   
       26 . A needle port as claimed in  claim 21 , further comprising:
 a converging wall located between the entrance opening and the means for preventing.   
   
   
       27 . A method for use with a needle having a pointed distal tip and a bevel where the needle diminishes in size down to the pointed distal tip, the method comprising the step of:
 engaging the bevel after the needle has passed through a septum to prevent further movement of the needle.   
   
   
       28 . A method as claimed in  claim 27   wherein the engaging the bevel comprises engaging the bevel with a surface after the needle has passed through a septum to prevent further movement of the needle; and   the method further comprises the step of funneling the needle toward the surface that engages the bevel after the needle has passed through the septum.   
   
   
       29 . A method as claimed in  claim 27   wherein the engaging the bevel comprises engaging the bevel with a surface that defines a hole after the needle has passed through a septum to prevent further movement of the needle; and   the method further comprises the step of funneling the needle toward the hole after the needle has passed through the septum and the pointed distal tip has passed through the hole.   
   
   
       30 . A method as claimed in  claim 27 , further comprising the step of:
 funneling the needle toward an entrance opening before the needle passes through the septum.   
   
   
       31 . A method as claimed in  claim 27 , further comprising the step of:
 funneling the needle toward an entrance opening defining a width and a length that is greater than the width before the needle passes through the septum.
