An apparatus for inserting a continuous analyte monitoring transmitter
A recently filed patent (Publication Number: US20230310029A1) describes a continuous analyte monitoring inserter apparatus. The apparatus includes an outer member and an inner member that can slide axially within the outer member. A transmitter carrier, which supports a transmitter and biosensor assembly, is housed within the inner member. The apparatus also includes an insertion device and a pivot member that can pivot to support the insertion device.
During the insertion process, the outer member slides over the inner member, pressing a bias member against the pivot member. This causes the pivot member to move the transmitter carrier and insertion device during the first portion of the stroke. In the second portion of the stroke, the pivot member pivots to retract the insertion device when the pivot member passes through an opening created by the overlapping of pivot windows in the outer and inner members. Once the second portion of the stroke is complete, a locking feature engages with the pivot window to prevent further pivoting, ensuring the biosensor remains inserted.
The apparatus also includes alignment features in the outer and inner members to vertically align the pivot windows. The pivot member has an insertion device support feature and a bias member interface feature to interact with the insertion device and bias member, respectively. The bias member, which is curved, contacts the inner and outer members as well as the pivot member during insertion.
The transmitter carrier, bias member, and other components can be formed from a single piece of material. The transmitter carrier includes a housing with a top region and a bottom region that supports the transmitter and biosensor assembly. A compression relief feature is positioned between these regions.
The inner member has a pre-insertion lock feature that extends into the pivot window of the outer member, preventing sliding until the insertion process begins. The bias member is flexible, and both the outer and inner members have an oval outer shape in cross-section.
The inner member includes retainer tangs that hold the transmitter and biosensor assembly, while the outer member has relief openings. The inner member's local contact features can snap into the relief openings, allowing the retainer tangs to move and release the assembly.
The patent also describes a method of forming the inserter apparatus, involving assembling the transmitter carrier assembly and inserting it into the inner member, which is then inserted into the outer member. The method also includes bending the bias member to contact the bias member interface feature of the pivot member.
Additionally, the patent outlines a method of inserting a biosensor using the inserter apparatus. The method involves pushing on the outer member to move the transmitter carrier and pivot member towards the insertion site. The insertion device inserts the biosensor, and the pivot member retracts the insertion device during the second portion of the stroke. The locking feature of the bias member prevents further pivoting after insertion.
