Medical instruments designed to safely and reliably access a patient’s bloodstream for diagnostic, therapeutic, or monitoring purposes. This category includes central venous catheters (CVCs), peripherally inserted central catheters (PICCs), port implants, and dialysis catheters. These devices enable long-term medication administration, fluid delivery, blood draws, and hemodialysis, reducing the need for repeated needle insertions and improving patient comfort and care efficiency.

Commode Chair

 A Commode Chair is a portable, standalone toilet designed for use at the bedside or in a room away from a bathroom. It consists of a chair frame with a seat opening and a removable collection bucket underneath. Its primary use is to provide a safe, convenient toileting solution for non-ambulatory, fall-risk, or post-operative patients, eliminating the need for hazardous trips to the bathroom. It is a critical tool for incontinence management, fall prevention, and preserving patient dignity. Rigorous cleaning and disinfection after each use are mandatory for infection control.

Ultrasonic Doppler

An Ultrasonic Doppler is a handheld or tabletop medical device that uses continuous wave Doppler ultrasound (2-10 MHz probes) to detect and amplify blood flow sounds for fetal heart rate monitoring and peripheral vascular assessment. Available with obstetric probes (2-3 MHz for deep fetal detection) and vascular probes (4-5 MHz for deep vessels, 8-10 MHz for superficial vessels). Features audio output through speaker or headphones, digital heart rate display (30-300 bpm), and directional flow capability on select models. Primary clinical applications include fetal heart rate detection and monitoring (as early as 10-12 weeks gestation), peripheral arterial disease assessment (ankle-brachial index calculation), deep vein thrombosis evaluation, blood pressure measurement in difficult populations, intraoperative and postoperative vascular monitoring, wound healing assessment, and penile blood flow evaluation for erectile dysfunction. Class II medical device requiring FDA clearance. Critical safety considerations include following ALARA principle for ultrasound exposure, appropriate gel use, probe pressure avoidance, infection control (probe cleaning and sterile covers), and qualified interpretation of Doppler sounds.
