Abstract

Provided is a fixation device for retaining a skin penetrating medical device, such as a cannula, on the skin of a patient. The fixation device includes a retaining component including a support layer having an adhesive coating, and a landing zone component, including a support layer having an adhesive coating, the landing zone component being adapted to be adhesively attached to the skin around the point of penetration. The retaining component acts as a skin-contacting component and is adapted to be applied on top of the landing zone component, and at least partially cover the medical device, such that the adhesive coating of the retaining component is applied to the support layer of the landing zone component. The adhesive coating of the retaining component includes a first adhesive, and the adhesive coating of the landing zone component includes a second adhesive, the first adhesive being different from the second adhesive.

Dependent claims

A fixation device for retaining a skin penetrating medical device on the skin of a patient, said fixation device comprising:

a retaining component, including a support layer having a first adhesive coating;
and
a landing zone component, including a support layer having a second adhesive coating, said landing zone component acting as a skin-contacting component and being adapted to be adhesively attached to the skin around a point of penetration of the skin penetrating medical device, wherein said landing zone component has a surface area that is larger than the surface area of the first adhesive coating of the retaining component,
wherein said retaining component is adapted to affix the medical device, and is adapted to be applied on top of the landing zone component to concentrate a load exerted by the skin penetrating medical device to a central area of the landing zone component, and at least partially cover the skin penetrating medical device, such that the first adhesive coating of the retaining component is applied to the support layer of the landing zone component, and wherein the first adhesive coating of the retaining component comprises a first adhesive, and the second adhesive coating of the landing zone component comprises a second adhesive, said first adhesive being different from said second adhesive, wherein the first adhesive of the retaining component comprises an acrylic adhesive, and the second adhesive of the landing zone component comprises a soft, skin-friendly adhesive comprising a silicone gel adhesive or soft hot-melt adhesive.

1 more element

A method of affixing a skin penetrating medical device to the skin of a patient comprising the steps of:

puncturing the skin of the patient with the skin penetrating medical device;
applying an adhesive landing zone component to the skin of the patient, said landing zone component comprising a support layer and an adhesive coating comprising a soft, skin-friendly adhesive comprising a silicone gel adhesive or soft hot-melt adhesive;
and
applying an adhesive retaining component on top of the landing zone component, and partially covering the skin penetrating medical device, so that an adhesive coating of the retaining component is applied to the support layer of the landing zone component to concentrate a load exerted by the skin penetrating medical device to a central area of the landing zone component, wherein the adhesive coating of the retaining component comprises an acrylic adhesive,
wherein said landing zone component has a surface area that is larger than the surface area of the first adhesive coating of the retaining component,
wherein the step of applying the adhesive landing zone component includes applying the adhesive landing zone component to the skin underneath the skin penetrating medical device, and applying the landing zone component to the skin in front of the skin penetrating medical device, and wherein the step of applying the landing zone component can be performed prior to or subsequent to puncturing the skin with the skin penetrating medical device.
