Objectives

The primary objective of this tender is to procure a single portable shortwave diathermy unit for clinical application within the Physiotherapy Department at the Ugu District Office. The procurement seeks to upgrade therapeutic capacity for musculoskeletal and post-surgical rehabilitation while ensuring compliance with national health technology standards, medical device safety regulations, and government preferential procurement frameworks.

Scope

The scope covers the complete supply, delivery, installation, commissioning, and initial training of one diathermy system. This is a once-off contract requiring the successful bidder to provide the main generator unit, all mandatory accessories, comprehensive operational and technical documentation, and full staff training. The contract includes a mandatory twelve-month guarantee period commencing upon successful commissioning and acceptance. During this period, the supplier must cover all maintenance, spare parts, travel expenses, routine servicing, and mandatory regulatory quality assurance testing. Bidders must also demonstrate local service capability and compliance with South African medical equipment standards.

Technical Requirements

• Therapy Modes & Output: The unit must deliver both pulsed and continuous shortwave therapy. Pulsed mode requires a peak output of approximately 1000W at a 70Ω load, with a variable pulse repetition frequency (15–200Hz, minimum ten selectable steps) and a pulse duration of approximately 400µs. Continuous mode must allow intensity adjustment from 0 to 400W at a 70Ω load.
• Safety & Control Systems: Automatic tuning must maintain constant power output despite patient movement. Switching from pulsed to continuous mode is prohibited unless output intensity is first reduced to minimum. A built-in digital countdown timer (0–30 minutes) with audible warning and automatic power shutdown is mandatory.
• Electrodes & Accessories: Supply of reusable glass/plastic capacitive and inductive rubber electrodes in small, medium, and large sizes. Includes adjustable/swiveling electrode arms, compatible interface cables, and dedicated hand tools/test lamps.
• Compliance & Build Quality: Must meet IEC 60601-2-3 safety standards for shortwave therapy equipment. The chassis must be robust, impact-resistant, and sealed against liquid ingress. Operating environmental range: 5–40°C.
• Documentation: Provision of original operation/maintenance manuals and service/repair manuals in English, including circuit diagrams, PCB layouts, calibration guides, part numbers, and mechanical exploded views.
• Unusual/Complicated Terms Explained: PCB-Level Training refers to advanced biomedical engineering instruction that enables hospital technicians to diagnose faults, calibrate circuits, and perform repairs directly on individual printed circuit boards, rather than merely swapping pre-assembled modules. Radiation Control Board QA Testing denotes mandatory periodic quality assurance and electromagnetic safety inspections mandated by South African health authorities, which must be fully covered under the warranty period.

Skills Requirements

• Biomedical Engineering Expertise: Bidders must employ or contract certified biomedical/electronics engineers capable of delivering manufacturer-equivalent, PCB-level technical training to institutional staff.
• Clinical & Regulatory Proficiency: Demonstrated understanding of shortwave diathermy physics, physiotherapy applications, IEC medical device safety standards, and national radiation control protocols.
• Local Service Infrastructure: Availability of a qualified service technician or authorized agent based in KwaZulu-Natal to ensure rapid response for warranty claims, routine maintenance, and emergency repairs.
• Training & Communication Competency: Ability to design and execute structured training programs for both clinical practitioners and technical personnel, including assessment, certification of competency, and provision of ongoing educational support.
