Abstract

A securement device, system, and method for use with a medical article. The securement device, system, or method may include a body that has a top surface and a bottom surface. The bottom surface has an adhesive compound thereon. A resilient retainer formed from a soft, tacky elastomeric gel or foam is supported by the bottom surface of the body. The resilient retainer receives and secures a medical device. The medical device is secured to the skin of a patient upon affixing the bottom surface to the patient via the adhesive compound.

a reinforcing filler;

a platinum catalyst; and

a hydrogen containing polysiloxane copolymer,

wherein a molar ratio of hydrogen to vinyl radicals in the total composition is less than 1.2, such that after curing, the degree to which said tacky, reinforced polysiloxane elastomer is partially crosslinked is about 30 to about 90%.

7. The securement device of claim 6, wherein the organopolysiloxane composition has a hardness of about 5 to about 55 durometer units (Shore 00), a tackiness of about 0 to about 450 grams as determined by a polyken probe tack tester or about 0 to about 7.6 cm as determined by a rolling ball tack tester and a tensile strength of about 0.14 to about 5.52 mega Pascals, a minimum elongation of about 250 to about 1100 percent and a tear strength of about 0.8 to about 35.2 kN/m.

8. The securement device of claim 1, wherein the organopolysiloxane composition comprises, based upon 100 parts total composition:

20 to 90 parts of a vinyl-containing high viscosity organopolysiloxane or a blend of high viscosity vinyl-containing organopolysiloxanes having no more than 25 mole percent of phenyl radicals and having a viscosity of 2,000 to 1,000,000 centipoise at 25°

C. of the formula;

9. The securement device of claim 1, wherein said elastomeric foam is a memory foam comprising polyurethane.

10. A method of securing a medical device to a patient, comprising:

providing a securement device for the medical device, and including a body having a top surface and a bottom surface, the bottom surface having an adhesive compound thereon, and a retainer formed from a soft, tacky elastomeric gel or an elastomeric foam, the retainer being supported by the bottom surface of the body and having a channel extending along a longitudinal axis, said channel being adapted for receiving a medical device, wherein the elastomeric gel is formed by curing an organopolysiloxane composition;

locating the medical device on the resilient retainer; and

securing the securement device and medical device to the patient with the body via the adhesive compound.

11. The method of claim 10, wherein the medical device is a catheter.

12. The method of claim 10, wherein the channel has a size and shape to receive at least a portion of the medical device.

13. The method of claim 12 further comprising filling a space between the channel and the medical device with a gel or foam.

14. The method of claim 13, wherein the gel or foam comprises spray gel or foam.

15. The method of claim 10, wherein said organopolysiloxane composition comprises:

a vinyl-containing high viscosity organopolysiloxane or a blend of high viscosity vinyl-containing organopolysiloxanes;

a low viscosity organopolysiloxane or a blend of low viscosity organopolysiloxanes;

a reinforcing filler;

a platinum catalyst; and

a hydrogen containing polysiloxane copolymer,

wherein a molar ratio of hydrogen to vinyl radicals in the total composition is less than 1.2, such that after curing, the degree to which said tacky, reinforced polysiloxane elastomer is partially crosslinked is about 30 to about 90%.

16. The method of claim 15, wherein the organopolysiloxane composition has a hardness of about 5 to about 55 durometer units (Shore 00), a tackiness of about 0 to about 450 grams as determined by a polyken probe tack tester or about 0 to about 7.6 cm as determined by a rolling ball tack tester and a tensile strength of about 0.14 to about 5.52 mega Pascals, a minimum elongation of about 250 to about 1100 percent and a tear strength of about 0.8 to about 35.2 kN/m.
