Adhesive and peripheral systems and methods for medical devices
Fill stations and base stations are provided for personal pump systems. The fill stations may be opened and closed to accept a reservoir and to allow fluid to be introduced into the reservoir for use with personal pump systems. The fill stations may hold the reservoir at a tilt relative to an underlying surface and may discourage overfilling of the reservoir. The filling stations may also include viewing windows having fluid lines marked thereon for indicating volume of fluid within the reservoir.
1. A method of filling a reservoir with a liquid therapeutic, the method comprising:
providing a fill station comprising:
a substantially rigid fill station base for holding the reservoir at a tilt; and
a substantially rigid fill station cover attached to the fill station base, the fill station cover having a filling aperture for receiving fluid from a syringe, the filling aperture having a length that controls penetration of a needle into the reservoir to prevent puncture of the reservoir, the fill station cover and the fill-station base defining a volume so as to prevent over filling of the reservoir;
placing the reservoir in the fill station and closing the fill station cover over the reservoir;
applying a syringe containing the liquid therapeutic to the filling aperture; and
ejecting the liquid therapeutic from the syringe through the filling aperture into the reservoir.
2. A method according to claim 1 , further comprising removing any remaining air in the reservoir after injecting a desired amount of liquid therapeutic into the reservoir.
3. A method according to claim 1 , further comprising viewing the amount of liquid in the reservoir through a window in the fill station cover.
4. A method according to claim 3 , further comprising estimating the amount of liquid by comparing the liquid level viewed through the window to a fluid-level indicia.
5. A fill station for filling a reservoir with a liquid therapeutic, the fill station comprising:
means for holding the reservoir at a tilt;
means for receiving fluid from a syringe;
means to prevent over-filling of the reservoir; and
means for estimating the fluid level of the reservoir even while the reservoir is held at a tilt;
wherein the means for holding the reservoir at a tilt includes a reservoir housing formed between a fill station base and a fill station cover, the fill station base having a surface for contacting the reservoir and supporting the reservoir thereon within the reservoir housing; and
wherein the surface for contacting the reservoir and supporting the reservoir thereon within the reservoir housing extends within the fill station base at a tilt relative to a surface underlying the fill station.
6. The fill station of claim 5 , further comprising wherein the means for holding the reservoir at a tilt comprising a substantially rigid base hingedly attached to a substantially rigid cover.
7. The fill station of claim 6 , further comprising wherein the substantially rigid cover further comprising a filling aperture whereby a syringe needle is inserted through to inject liquid into reservoir and wherein the rigid cover limits the travel of the syringe with respect to the filling aperture.
8. The fill station of claim 5 , further comprising wherein the means for holding the reservoir at a tilt comprising a leg and whereby air will rise upwardly toward a fill aperture in a cover on the fill station.
9. The fill station of claim 5 , further comprising wherein the means to prevent over-filling comprises a viewing window for viewing a fluid line whereby the fluid line indicates the volume of liquid in the reservoir.
