Description
Inclusion Criteria:
- Clinical diagnosis of type 1 diabetes for at least 12 months
- Using an insulin pump for at least 12 months
- Age ≥18 years
- Hemoglobin A1c level less than or equal to 8.5%
- Willing to use mylife™ YpsoPump® system while they are participating in the study
- Willing to use NovoRapid® insulin while they are participating in the study
- An understanding of and willingness to follow the protocol and sign the informed consent
Exclusion Criteria:
- Diabetic ketoacidosis in the past 3 months prior to enrollment
- Severe hypoglycemia resulting in seizure or loss of consciousness in the 3 months prior to enrollment
- Urea, Creatinine, ALT more than three times the upper limit of normal, or thrombocytopenia (<150 G/l)
- Female subjects: pregnancy, lactation period, lack of a negative pregnancy test (except in case of menopause, sterilization or hysterectomy), or unwilling to use an acceptable form of contraception during the study (for sexually active subjects of childbearing potential)
- Known severe tape reactions or allergies
- Known severe nickel allergies
- History of frequent catheter abscesses associated with pump therapy
- Serious acute or chronic disease besides diabetes mellitus or an anamnesis which might, in the opinion of the investigator, pose a risk to the subject, e.g. seizure disorder, adrenal disorder, dialysis for renal failure, cystic fibrosis, active infection
- Any incapacity or general condition that, in the opinion of the investigator, prevents adequate compliance with the study procedures, e.g. mental or visual incapacity, language barriers, alcohol or drug misuse
- Dependency from the sponsor or the clinical investigator

Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Experimental: Soft cannula first
Subjects will be randomized (50%) to the soft cannula infusion set for two weeks and then will be switched to the steel needle infusion set for two additional weeks.
Participants will aim for 7 day use of each infusion set type twice, starting with the soft cannula infusion set.

Insulin infusion sets will be used for up to 7 days or until failure

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Time to infusion set failure due to an occlusion
Time Frame: up to 7 days
|
an occlusion is defined by blood ketone concentration is > or = 0.6 mmol/l with blood glucose (BG) concentration >250 mg/dl, or BG concentration is >250 mg/dl for more than 2 h and a subsequent correction bolus failed, or pump occlusion alarm that cannot be fixed.
|
up to 7 days
