Reduced-spill hydrophilic catheter product with foamed hydration liquid
A reduced-spill urinary catheter product including a package containing a hydrophilic catheter and a foamed hydration liquid. The package having a void volume between the catheter and inner boundary of the package. The foamed hydration liquid having a density wherein the ratio of the density of the foamed liquid hydration medium to the volume of the void volume is less than 0.5.
1 . A catheter product, comprising:
a package comprising an inner boundary defining a cavity of the package;
a catheter located within the cavity of the package;
a void volume defined between an outer surface of the catheter and inner boundary of the package, the void volume having a volume (milliliters);
a foamed liquid hydration medium located in the void volume, wherein the foamed liquid hydration medium fills the entire void volume or substantially the entire void volume, the foamed liquid hydration medium having a density (grams per milliliters); and
wherein a ratio of the density of the foamed liquid hydration medium to the volume of the void volume is less than 0.5.
2 . The catheter product of claim 1 , wherein the ratio of the density of the foamed liquid hydration medium to the volume of the void volume is less than 0.1.
3 . The catheter product of claim 1 , wherein the density of the foamed liquid hydration medium is between 0.05 g/ml and 0.5 g/ml.
4 . The catheter product of claim 1 , wherein the density of the foamed liquid hydration medium is between 0.08 g/ml and 0.1 g/ml.
5 . The catheter product of claim 1 , wherein the foamed liquid hydration medium has a volume between 1 ml and 10 ml.
6 . The catheter product of claim 1 , wherein the foamed liquid hydration medium includes a liquid having a weight between 0.1 grams and 1 grams.
7 . The catheter product of claim 1 , wherein the void volume has a volume of between 3 ml and 100 ml.
8 . The catheter product of claim 1 , wherein the void volume has a volume of between 3 ml and 6 ml.
9 . The catheter product of claim 1 , wherein the void volume has a volume of 4 ml.
10 . The catheter product of claim 1 , wherein the foamed liquid hydration medium includes a surfactant.
11 . A method of making a catheter product, comprising:
placing a catheter and foamed hydration liquid into a cavity of a package wherein a void volume of the cavity is defined between an outer surface of the catheter and inner boundary of the package, wherein the foamed hydration liquid occupies the entire void volume, or substantially the entire void volume, of the cavity;
closing the package; and
wherein the foamed hydration liquid has a density (grams per milliliters) and the void volume has a volume (milliliters), and wherein a ratio of the density of the foamed hydration liquid to the volume of the void volume is less than 0.5.
12 . The method of claim 11 , wherein the ratio of the density of the foamed hydration liquid to the volume of the void volume is less than 0.2.
13 . The method of claim 11 , further including foaming a hydration liquid so as to comprise a density between 0.05 g/ml and 0.5 g/ml.
14 . The method of claim 13 , wherein the density of the foamed hydration liquid is between 0.08 g/ml and 0.1 g/ml.
15 . The method of claim 11 , wherein the foamed hydration liquid has a volume between 1 ml and 10 ml.
16 . The method of claim 11 , wherein the foamed hydration liquid includes a liquid having a weight between 0.1 gram and 1 gram.
17 . The method of claim 11 , wherein the void volume has a volume of between 3 ml and 100 ml.
18 . The method of claim 11 , wherein the void volume has a volume of between 3 ml and 6 ml.
19 . The method of claim 11 , wherein the void volume has a volume of 4 ml.
20 . The method of claim 11 , wherein the foamed hydration liquid includes a surfactant.
