Class I medical devices are: ordinary surgical knives and scissors, dressings and so on.
The second class of medical devices are: X-ray film machine, ultrasound, microscope, biochemistry and so on.
Three types of medical devices are: medical electronic instruments and equipment, medical optical instruments, instruments and endoscopic equipment, medical magnetic **** vibration equipment, medical X-ray equipment, operating room, emergency room, diagnostic and treatment room equipment and appliances, medical polymer materials and products, clinical testing and analytical instruments, in vitro diagnostic reagents, medical electronic instruments and equipment, disinfection and sterilization equipment and appliances and so on.
Listed below:
1, dressings
Dressings are used for the main material outside the auxiliary materials, mainly refers to the 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, biochemistry
Biochemistry is based on the principle of photoelectric colorimetry to measure the body fluids in a particular chemical composition of the instrument. Because of its fast measurement speed, high accuracy, small consumption of reagents, is now widely used at all levels of hospitals, epidemic prevention stations, family planning service stations. Used in conjunction with can greatly improve the efficiency of routine biochemical testing and revenue.
3, clinical testing and analyzing instruments
Clinical testing and analyzing instruments is a class of disease prevention, diagnosis and research, as well as therapeutic testing, drug analysis of precision equipment. With a wide range of technical areas involved, complex structure, high precision, advanced technology and other characteristics.
4, medical polymer materials
Medical polymer materials are used to manufacture human organs, organs in vitro, drug dosage forms and medical equipment polymer materials, the source of which includes natural biopolymers and synthetic biopolymers. Natural medical polymer materials from nature, including cellulose, chitin, hyaluronic acid, collagen, gelatin and sodium alginate, etc.;
Synthetic medical polymer materials is through chemical methods, synthetic polymer materials for medical use, the current commonly used polyurethane, silicone rubber, polyester fibers, polyethylene-based pyrrolidone, polyether ether ketone, polyethylene glycol, polyvinyl alcohol, polyvinyl lactic acid, polyethylene and so on. polyvinyl alcohol, polylactic acid, polyethylene, etc.
5, operating room
Operating room (operating room in English referred to as o.r.) is to provide patients with surgical and rescue places, is an important technical department of the hospital. Operating room should be connected with the surgical department, but also with the blood bank, monitoring room, anesthesia resuscitation room and other proximity. Grasp the surgical incision infection of the four pathways of link management, namely: the operating room air; items needed for surgery;
Doctors and nurses of the fingers and the patient's skin, to prevent infection, to ensure the success rate of surgery. Requirements for a rational design, well-equipped, responsive nurses work, fast, with efficient work efficiency. Operating room to have a set of strict and reasonable rules and regulations and aseptic operation norms. With the rapid development of surgical technology, the operating room work is increasingly modernized.
