Abstract

Methods and apparatuses for performing an insertion process for a plurality of penetrating elements are described. For example, a wearable fluid infusion device may include a cannula and/or needle for infusing a fluid into a patient and a sensor for sensing a physical characteristic of the patient. A non-limiting example of a fluid may be or may include insulin. An illustrative and non-restrictive example of a physical characteristic may include a blood glucose level. The wearable infusion device may be configured to facilitate insertion of the multiple penetrating elements, such as a cannula and a sensor, in a single simultaneous insertion step instead of requiring individual insertion steps for each of multiple penetrating elements. Other embodiments are described.

Claims (13)

1 . A fluid delivery device, comprising:

a fluid delivery penetration element operative to be inserted into a patient to deliver a fluid from a fluid delivery system to the patient;

a sensor device comprising a sensor penetration element operative to be inserted into the patient to measure patient information of the patient;

a catch coupled to the sensor penetration element; and

an activation device operative to force the fluid delivery penetration element to be inserted into a portion of the patient, the fluid delivery penetration element to engage the catch when traveling toward the portion of the patient to force the sensor penetration element into the portion of the patient.

2 . The fluid delivery device of claim 1 , the fluid delivery penetration element comprising at least one of a cannula and a needle.

3 . The fluid delivery device of claim 1 , the sensor device comprising a continuous glucose monitoring (CGM) device, wherein the sensor penetration element comprises a CGM sensor.

4 . The fluid delivery device of claim 1 , the sensor device comprising a housing having a seal arranged on an outer surface thereof, the fluid delivery penetration element to pierce the seal as the fluid delivery penetration element travels to engage the catch.

5 . The fluid delivery device of claim 1 , the fluid delivery penetration element comprising at least one engagement element operative to facilitate engagement of the fluid delivery penetration element with the catch.

6 . The fluid delivery device of claim 1 , the catch comprising a funnel.

7 . The fluid delivery device of claim 1 , the catch arranged on an insertion needle coupled to the sensor penetration element.

8 . The fluid delivery device of claim 1 , the fluid delivery device and the sensor device independently coupled to the portion of the patient via separate adhesive areas.

9 . The fluid delivery device of claim 1 , the activation device operative to retract the fluid delivery penetration element from the portion of the patient without removing the sensor penetration element from the portion of the patient.
