What are Class 1, 2 and 3 medical devices?

Detailed catalog.

Class I medical devices include: ordinary surgical knives, scissors, dressings, etc.

Class II medical devices include: X-ray film machines, B-ultrasounds, microscopes, biochemical instruments, etc.

The three categories of medical equipment include: medical electronic equipment, medical optical equipment, instruments and endoscopic equipment, medical magnetic resonance imaging equipment, medical X-ray equipment, operating room, emergency room, diagnosis room equipment and appliances, and medical polymers

Materials and products, clinical testing and analysis instruments, in vitro diagnostic reagents, medical electronic instruments and equipment, disinfection and sterilization equipment and appliances, etc.

Listed below: 1. Dressings Dressings refer to auxiliary materials used in addition to the main materials of items, mainly referring to hemostatic gauze (usually medical skim gauze).

Traditional dressings are mainly dry gauze and oil gauze.

Modern wound dressings include interactive wound dressings, calcium alginate dressings, silver dressings, foam dressings, hydrocolloid dressings, and hydrogel dressings.

2. Biochemical instrument A biochemical instrument is an instrument that measures a specific chemical component in body fluids based on the principle of photoelectric colorimetry.

Due to its fast measurement speed, high accuracy, and small consumption of reagents, it has been widely used in hospitals, epidemic prevention stations, and family planning service stations at all levels.

Used together, the efficiency and benefits of routine biochemical testing can be greatly improved.

3. Clinical testing and analysis instruments Clinical testing and analysis instruments are a type of precision equipment used for disease prevention, diagnosis and research, as well as treatment testing and drug analysis.

It has the characteristics of covering a wide range of technical fields, complex structure, high precision and advanced technology.

4. Medical polymer materials Medical polymer materials refer to polymer materials used to manufacture human internal organs, external organs, pharmaceutical dosage forms and medical devices. Their sources include natural biopolymer materials and synthetic biopolymer materials.

Natural medical polymer materials are derived from nature, including cellulose, chitin, hyaluronic acid, collagen, gelatin, sodium alginate, etc.; synthetic medical polymer materials are artificially synthesized polymer materials for medical use through chemical methods.

, currently commonly used ones include polyurethane, silicone rubber, polyester fiber, polyvinylpyrrolidone, polyetheretherketone, polymethyl methacrylate, polyvinyl alcohol, polylactic acid, polyethylene, etc.

5. Operating room The operating room (operating room, abbreviated as o.r in English) is a place that provides surgery and rescue for patients. It is an important technical department of the hospital.

The operating room should be connected to the surgical department, and should also be close to the blood bank, intensive care unit, anesthesia recovery room, etc.

Pay close attention to the management of the four channels of surgical incision infection, namely: the air in the operating room; the items required for surgery; the fingers of doctors and nurses and the patient's skin to prevent infection and ensure the success rate of surgery.

It is required that the design is reasonable, the equipment is complete, the nurses work responsively, quickly, and have high work efficiency.

The operating room must have a set of strict and reasonable rules and regulations and aseptic operating procedures.

With the rapid development of surgical technology, operating room work is becoming increasingly modern.
