Abstract
Embodiments relate to subcutaneous insertion systems comprising a surface device to be applied to a patient's skin and an insertion system for applying the surface device to the patient, wherein the applying can include subcutaneous insertion of a cannula or other element, and related devices and methods. The surface device comprises a surface for application to the skin of a patient and a subcutaneous element, such as a cannula, wire, filament or other device, extending from the skin's surface at an angle greater than 0 degrees and less than 90 degrees.
Claims21
An insertion device comprising:
- a housing comprising a first end;
- a sleeve slidably arranged at least partially in the housing;
- a cylinder hub at least partially arranged in the sleeve and the housing and comprising a shoulder portion, a body portion and an end portion, the shoulder portion proximate to the first end of the housing;
- a needle hub slidably arranged in the cylinder hub and comprising a needle;
- and
- a site comprising a patient-side surface, a central hub having a side aperture formed therein, a subcutaneous element coupled to the site at an angle greater than 0 degrees and less than 90 degrees with respect to the patient-side surface, and a septum having a longitudinal axis that is coaxial with a longitudinal septum axis of the central hub extending substantially orthogonally from the patient side surface, the site arranged within the housing such that the needle can pass through the side aperture of the central hub and pass through the septum at an oblique angle relative to the longitudinal septum axis, to enter the subcutaneous element at the oblique angle.
A method comprising:
- providing an insertion device comprising
- a housing comprising a first end,
- a sleeve slidably arranged at least partially in the housing,
- a cylinder hub at least partially arranged in the sleeve and the housing and comprising a shoulder portion, a body portion and an end portion, the shoulder portion proximate to the first end of the housing, and
- a needle hub slidably arranged in the cylinder hub and comprising a needle;
- providing a site to be applied by the insertion device, the site comprising a patient-side surface, a central hub having a side aperture formed therein, a subcutaneous element to be inserted by the insertion device, the subcutaneous element coupled to the site at an angle greater than 0 degrees and less than 90 degrees with respect to the patient-side surface, and a septum having a longitudinal axis that is coaxial with a longitudinal septum axis extending substantially orthogonally from the patient side surface;
- and
- configuring the insertion device and the site to be coupled with one another such that the needle can pass through the side aperture of the central hub and pass through the septum at an oblique angle relative to the longitudinal septum axis, to enter the subcutaneous element at the oblique angle to insert the subcutaneous element during use.
An insertion device comprising:
- a housing comprising a first end;
- a sleeve slidably arranged at least partially in the housing;
- a cylinder hub at least partially arranged in the sleeve and the housing and comprising a shoulder portion, a body portion and an end portion, the shoulder portion proximate to the first end of the housing;
- and
- a needle hub slidably arranged in the cylinder hub and comprising a needle;
- wherein the insertion device is configured to be coupled with a site to insert a subcutaneous element of the site subcutaneously, the subcutaneous element coupled to the site at an angle greater than 0 degrees and less than 90 degrees with respect to a patient-contacting surface of the site, the subcutaneous element secured in place with a septum having a longitudinal septum axis extending substantially orthogonally from the patient-contacting surface, the site coupled with the insertion device such that the needle can pass through at least a side aperture formed in a central hub of the site and pass through the septum at an oblique angle relative to the longitudinal septum axis, to enter the subcutaneous element at the oblique angle.
