An infusion set comprising a base and a cap. The base can comprise a portion to be placed against skin, a first cannula extending downwardly below the portion to be placed against skin, and a septum. The cap can comprise a tube and a second cannula. The cap can be configured for removable attachment to the base such that the cap is rotatable with respect to the base while the first cannula, the second cannula, and the tube are in fluid communication.

Infusion hub assembly and fluid line disconnect system

An infusion hub assembly, comprising: a hub received in a hole in a wing, the hub having a bore passing therethrough, with an upper portion of the circular hub having an attachment surface thereon; an infusion cannula extending downwardly away from the wing, the infusion cannula being in fluid communication with the bore passing through the hub; a cover having a bore passing therethrough and having an inner attachment surface adapted to mate with the attachment surface on the upper portion of the hub; and a septum positioned in alignment with the bore passing through the cover. An infusion connector set comprising: a first connector; a septum received in the first connector; a second connector; a septum received in the second connector; and a flanged needle which penetrates both the septums in the first and second connectors when the first and second connectors are connected together.

An infusion set includes a needle hub with a needle to be inserted in a through passageway of the cannula housing through a sealing surface of a soft cannula. The infusion set includes a guide for centering the needle relative to the cannula sealing surface, a dirt trap, and the through passageway, as well as a locking device for locking the cannula housing and the needle hub together to prevent inadvertent disengagement. The guide includes co-operating guide pins and guide openings and a draft angle on the needle hub. The pins are located on each side of the needle and the through passageway. The connecting tube includes an inner tube of polyethylene and shrink fitted tubing at each end suitable for a solvent bonding layer. The composite can be reinforced with monofilament strands sandwiched between the two tubular layers to prevent kinking, or the inner tube can be formed in a triangular shape. The triangular shape composite is incased in a thin polyester shrink tube.

Subcutaneous injection set for use with a reservoir that has a septum

An infusion hub assembly, comprising: a hub received in a hole in a wing, the hub having a bore passing therethrough, with an upper portion of the circular hub having an attachment surface thereon; an infusion cannula extending downwardly away from the wing, the infusion cannula being in fluid communication with the bore passing through the hub; a cover having a bore passing therethrough and having an inner attachment surface adapted to mate with the attachment surface on the upper portion of the hub; and a septum positioned in alignment with the bore passing through the cover.

The infusion set comprises of a connecting tube of polyethylene which is treated to form a wetable surface or treated with a primer and then bonded to a PVC hub by using solvent adhesive to solvent bond the low density polyethylene tubing or Teflon tubing to a PVC hub. The surface treatment methods include a methane plasma surface that is applied to tubing in a continuous manner and alternatively a primer that is applied locally and dried prior to applying the adhesive. Both techniques form a strong and resilient bond for the infusion needle and tube when assembled to the PVC hubs.

Subcutaneous injection set tubing with solvent bonding

A medication injection or delivery system is provided for injecting fluids such as insulin within body tissue. The device includes a housing, a flexible shaft movably mounted within the housing, and a dose setting mechanism for controlling the movement of the shaft with respect to a fluid-containing cartridge removably positioned within or mounted to the housing. The flexible shaft, according to exemplary embodiments, includes a plunger and a flexible cable connected to the dose setting mechanism. The plunger and dose setting mechanism are connected together by the flexible shaft. The dose setting mechanism, in one aspect of the invention, includes a screw, a locking mechanism, and a nut assembly connected to the flexible shaft. The dose setting mechanism is used to set the dosage and prime the catheter. The plunger retracts into a recess to permit a new cartridge to be installed quickly.
