US5221271A — Sample site with flow directors

Claim 1

Independent Claim 59 words

A sample site comprising: a housing having a cavity therein; seal means for selectively accessing fluid in the cavity; A pair of ports connected to the housing and in fluid communication with the cavity; and flow director means in the ports for creating non-laminar flow of fluid in the cavity from one of the ports to the other port.

Claim 2

Dependent Claim 59 words

A sample site comprising: a housing having a cavity therein; seal means for selectively accessing fluid in the cavity; A pair of ports connected to the housing and in fluid communication with the cavity; and flow director means in the ports for creating non-laminar flow of fluid in the cavity from one of the ports to the other port.

Claim 3

Dependent Claim 15 words

The sample site of claim 1, the ports being oppositely disposed along a common axis.

Claim 4

Dependent Claim 23 words

The sample site of claim 1, the flow director means including a ramp in at least one of the ports adjacent the cavity.

Claim 5

Dependent Claim 21 words

The sample site of claim 1, the flow director means including a ramp in each of the ports adjacent the cavity.

Claim 6

Dependent Claim 14 words

The sample site of claim 4, the ramps being rotated 180° relative each other.

Claim 7

Dependent Claim 24 words

The sample site of claim 1, the flow director means being positioned in the ports such that they are rotated 180° relative each other.

Claim 8

Dependent Claim 89 words

A sample site comprising: a housing having a cavity therein; seal means for selectively accessing fluid in the cavity; a pair of ports connected to opposite sides of the housing, the ports being in fluid communication with the cavity through an inlet in each of the ports; and a first flow director within a first of the ports whereby to diver fluid entering the cavity through the port from flowing along a direct line from the inlet of one of the ports to the inlet of the other port

Claim 9

Dependent Claim 89 words

A sample site comprising: a housing having a cavity therein; seal means for selectively accessing fluid in the cavity; a pair of ports connected to opposite sides of the housing, the ports being in fluid communication with the cavity through an inlet in each of the ports; and a first flow director within a first of the ports whereby to diver fluid entering the cavity through the port from flowing along a direct line from the inlet of one of the ports to the inlet of the other port

Claim 10

Dependent Claim 28 words

The sample site of claim 7, the first flow director including a ramp surface extending away from the interior wall of the first port and towards the cavity.

Claim 11

Dependent Claim 28 words

The sample site of claim 8 wherein the ramp surface extends to the cavity so as to define a semicircular cross-section to the inlet of the first port.

Claim 12

Dependent Claim 12 words

The sample site of claim 8 wherein the ramp surface is flat.

Claim 13

Dependent Claim 37 words

The sample site of claim 7 further comprising: a second flow director within a second of the ports whereby to divert fluid entering the cavity through that port from flowing along a direct line between the inlets.

Claim 14

Dependent Claim 28 words

The sample site of claim 11, the flow directors each including a ramp surface extending away from the interior wall of the associated port and towards the cavity.

Claim 15

Dependent Claim 76 words

A sample site comprising: a housing having a cavity therein; seal means for selectively accessing fluid in the cavity; a pair of ports connected to opposite sides of the housing along a common axis, the ports being in fluid communication with the cavity through inlets in the ports; and a first ramp surface within a first of the ports adjacent the inlet thereof to produce a flow from one of the ports to the other port.

Claim 16

Dependent Claim 76 words

A sample site comprising: a housing having a cavity therein; seal means for selectively accessing fluid in the cavity; a pair of ports connected to opposite sides of the housing along a common axis, the ports being in fluid communication with the cavity through inlets in the ports; and a first ramp surface within a first of the ports adjacent the inlet thereof to produce a flow from one of the ports to the other port.

Claim 17

Dependent Claim 27 words

The sample site of claim 13, the ramp surface being connected to the interior wall of the first port at a location spaced from the inlet thereof.

Claim 18

Dependent Claim 28 words

The sample site of claim 14 wherein the ramp surface extends to the cavity so as to define a semicircular cross-section to the inlet of the first port.

Claim 19

Dependent Claim 22 words

The sample site of claim 13 further comprising a second ramp surface within a second of the ports adjacent the inlet thereof.

Claim 20

Dependent Claim 27 words

The sample site of claim 16, each ramp surface being connected to the interior wall of the associated port at a location spaced from the inlet thereof.

Claim 21

Dependent Claim 28 words

The sample site of claim 16 wherein each ramp surface extends to the cavity so as to define a semicircular cross-section to the inlet of the associated port.

Claim 22

Dependent Claim 17 words

The sample site of claim 16, each of the ramp surfaces being aimed in a different direction.

Claim 23

Dependent Claim 15 words

The sample site of claim 16, the ramp surfaces being rotated 180° relative each other.
