ABSTRACT:
The disclosures made herein relate to an infusion device specifically adapted for syringe injections. In one embodiment of the disclosures made herein, an infusion device comprises a body including an accessible surface having a single inlet port therein, an engagement surface having a single outlet port therein, a medication delivery channel extending between the single inlet port and the single outlet port, and an identification feature on the accessible surface of the body adjacent to the single inlet port. The single inlet port of the medication delivery channel is tapered thereby forming a funnel-shaped entry into the medication delivery channel. A cannula is coupled to the body at the single outlet port and is adapted for receiving medication from the single outlet port and transmitting the medication therethrough. The cannula has an essentially straight longitudinal axis that extends generally perpendicular to the engagement surface of the body. A first self-sealing member is attached to the body and forms a first septum for the medication delivery channel. A needle stop is positioned within the medication delivery channel. An infusion device in accordance with embodiments of the disclosures made herein may be mounted on a patient with the cannula extending into or through subcutaneous tissue of the patient. Once the infusion device is mounted on the patient, the patient may use a syringe and injection needle for receiving an injection of one or more medications via the infusion device. An advantage of receiving an injection via an infusion device as disclosed herein is that the patient is spared having their skin pierced by the injection needle. After an initial skin piercing by an insertion needle of the infusion device, all injections are facilitated via the injection needle being engaged with the infusion device rather than through the skin of the patient.
