Systems and methods related to collection of biological fluids

Abstract

Collection of biological fluids. At least one example is a polymeric sleeve including: an elongate body that defines a main passageway; an internal chamber defined within the main passageway; a first flange suspended within the internal chamber at a first position along the longitudinal central axis; and an aperture through the first flange, the aperture at least partially aligned with the longitudinal central axis.

         12 . A method of making a polymeric sleeve comprising:
 placing a lower mold component, the lower mold component structurally defines a negative image of an insertion end of the polymeric sleeve, and the lower mold component defines a negative image of a first portion of a main passageway of the polymeric sleeve;   assembling into mating relationship a disk assembly, the disk assembly structurally defines a negative image of an internal volume of the polymeric sleeve, and the disk assembly defines a negative image of at least two stanchions and a first flange;   stacking the disk assembly into mating relationship with the lower mold component;   coupling a rod member to the disk assembly, an exterior surface of the rod member defines a negative image of the main passageway from the internal volume to a vent end of the polymeric sleeve;   closing an outer mold assembly around the disk assembly and rod member, an interior surface of the outer mold assembly structurally defines a negative image of an outer surface of the polymeric sleeve; and   injecting a polymeric compound in a liquid state into the outer mold assembly.

         14 . The method of  claim 13  wherein the lower disk member and the upper disk member, when assembled, define a negative image of a first stanchion at a first radial direction, a second stanchion at a second radial direction and a third stanchion at a third radial direction. 
     
     
         15 . The method of  claim 12  wherein assembling further comprises:
 abutting a lower disk member against a medial disk member, and abutting the medial disk member against an up upper disk member; 
 the lower disk member and medial disk member define the negative image of at least two stanchions and the first flange; and 
 the medial disk member and the upper disk member define a negative image of at least two stanchions and a second flange. 
 
     
     
         16 . The method of  claim 12  wherein assembling further comprises:
 abutting a lower disk member against a medial disk member, and abutting the medial disk member against an up upper disk member; 
 the lower disk member and medial disk member defines a negative image of three stanchions and the first flange; and 
 the medial disk member and the upper disk member define a negative image of three stanchions and a second flange. 
 
     
     
         17 . A mold system for creating a polymeric sleeve, the mold system comprising:
 a lower mold defining a mold surface and a stem that protrudes upward from the mold surface along a longitudinal axis;   a disk assembly configured to stack into mating relationship with an upper end of the stem, the disk assembly defining at least two channels into a first interior volume that circumscribes the longitudinal axis; and   a rod configured to couple to an upper surface of the disk assembly and extend along the longitudinal axis.   
     
     
         18 . The mold system of  claim 17  wherein the disk assembly further comprises a lower disk member and an upper disk member, the lower and upper disk members defining three channels into the interior volume, the three channels extending along three distinct radial directions relative to the longitudinal axis. 
     
     
         19 . The mold system of  claim 17  wherein the disk assembly further comprises:
 a lower disk member abutting a medial disk member, and the medial disk member abutting an upper disk member; 
 the lower disk member and medial disk member defining at least two channels into the first interior volume; and 
 the medial disk member and the upper disk member defining at least two channels into a second interior volume, the second interior volume circumscribing the longitudinal axis. 
 
     
     
         20 . The mold system of  claim 17  wherein the disk assembly further comprises:
 a lower disk abutting a medial disk member, and the medial disk member abutting an upper disk member; 
 the lower disk member and medial disk member defining a first, second, and third channels into the first interior volume, the first, second, and third channels extending along a first, second, and third radial directions, respectively; and 
 the medial disk member and upper disk member defining a fourth, fifth, and sixth channels into a second interior volume that circumscribes the longitudinal axis, the fourth, fifth, and sixth channels extending along a fourth, fifth, and sixth radial directions, respectively. 
 
     
     
         21 . The mold system of  claim 20  wherein the first radial direction is 60 angular degrees from the fourth radial direction.
