简要总结
This is an explorative, monocentric, feasibility study to evaluate the detectability of the bladder in healthy subjects by ultrasound monitoring with the early prototype of a future bladder sensor, which is intended for use for an individual suffering from urinary incontinence.
详细描述
The purpose of this clinical investigation with healthy subjects (defined as subjects without urological problems or lower urinary tract symptoms, assured by pre-defined inclusion and exclusion criteria) is to collect raw measurement data of the urinary bladder region of volunteers with the TENA-PROTO1, in multiple postural positions to evaluate the detectability of the bladder in the intended users and to determine the position criteria for the (future) ultrasound sensor on the lower abdomen. Secondarily, this clinical investigation aims to collect data on the adhesive and supportive belt used to fix the transducer assembly to the lower abdomen by the subject. Furthermore, safety of the subjects will be continously documented such as adverse events (AE) and device deficiencies (DD); AEs, Adverse Device Events (ADE), Severe Adverse Events (SAE), Severe Adverse Device effects (SADE), Unanticipated Serious Adverse Device Effects (USADE) and DDs.

研究组 & 干预措施
TENA-PROTO1
Investigational device. Early prototype
干预措施: TENA-PROTO1 (Device)
结局指标
主要结局
Bladder detectability rate as a function of gender, BMI, age, sensor position, posture and combinations of these variables
时间窗: 4 months
Percentage of those, where the bladder was detected in total or regarding different subgroups (BMI, age, sex, postural positions and sensor location ) based on raw measurement data of the urinary bladder region of volunteers with the early prototype of the Bladder Sensor in multiple postural positions to evaluate the detectability of the bladder in the intended users
Raw measurement data for the development of an algorithm to determine the bladder filling status
时间窗: 4 months
Raw data, that has been assessed by the prototype (TENA-PROTO1) will be used to develop a product specfic algorithm (R\&D outcome)
次要结局
- Evaluation of the fixation methods and device regarding user needs by the subjects on a score(4 months)
- Any adverse event (AE) or device deficiency (DD)(Ongoing documentation after enrolment until end of the measurement day (4 months))
