People who work in hospitals always deal with various medical devices, but this is normal. After all, if you want to do your job well, you must first sharpen your tools. Only with medical equipment can you better treat patients. So what are the medical equipment? Today, the editor of Xianji.com will tell you in detail and introduce the common types, uses and technical requirements of medical devices. Let's listen to it!

What are the medical devices?

Medical devices in hospitals can be divided into three categories, namely diagnostic and therapeutic categories and different requirements for each level of necessary medical devices.

Diagnostic equipment can be divided into the following categories:

Physical diagnostic instruments (thermometers, sphygmomanometers, microscopes, audiometers, various physiological recorders, etc.), imaging (X-ray machines, CT scans, magnetic resonance imaging, B-ultrasound, etc.), analytical instruments (various types of counters, biochemical, immunoassay instruments, etc.), electrophysiological instruments (such as electrocardiographs, electroencephalographs, electromyography, etc.).

2. Treatment equipment can be divided into the following categories:

General surgical instruments, optical surgical instruments (fiber endoscopes, laser therapy machines, etc.); auxiliary surgical instruments (such as various anesthesia machines, ventilators, extracorporeal circulation, etc.); radiotherapy machines (such as deep X-ray therapy machines, cobalt 60 therapy machines, accelerators, gamma knives, various isotope therapy machines, etc.); other categories (microwaves, hyperbaric oxygen, etc.).

3. The grade requirements of medical devices required by hospitals can be divided into three categories:

Class I, Class II and Class III. That is, Class I refers to medical devices that are sufficient to ensure their safety and effectiveness through routine management; Class II refers to medical devices whose safety and effectiveness should be controlled; Class III refers to medical devices that are implanted in the human body, used to support and maintain life; and are potentially dangerous to the human body and whose safety and effectiveness must be strictly controlled.

It is worth noting that if a medical device contains Class I and Class II, then this medical device is Class II. If a medical device contains Class II and Class III, then this medical device belongs to Class III. By analogy, everyone can draw the same conclusion.

Various simple medical devices for home use, such as thermometers, stethoscopes, sphygmomanometers, etc. With the development of electronic technology, automatic and semi-automatic electronic home medical devices such as electronic sphygmomanometers, blood glucose testers, electronic thermometers, etc. have been launched one after another.

Common types of medical devices:

Home health care equipment:

Pain massage equipment, home health care self-testing equipment, sphygmomanometers, electronic thermometers, multi-functional therapeutic instruments, laser therapeutic instruments, blood glucose meters, diabetes therapeutic instruments, vision improvement equipment, sleep improvement equipment, oral hygiene and health products, home emergency treatment products.

Home care equipment:

Home rehabilitation nursing aids, women's pregnancy and baby care products, home supply and transmission equipment, oxygen cylinders, oxygen bags, home first aid kits, blood pressure monitors, blood glucose meters, nursing beds.

New medical equipment:

With the development of science and technology, the scientific and technological achievements of some colleges and universities have also been rapidly transformed into results. Patented products produced by some new manufacturers have also appeared in the market. Including some equipment commonly used in homes and hospitals, such as medical trauma treatment vehicles, etc.

Common medical equipment in hospitals:

Trauma treatment vehicles, operating tables, operating lights, monitors, anesthesia machines, ventilators, blood cell analyzers, differentiation analyzers, enzyme markers, plate washers, urine analyzers, ultrasound machines (color ultrasound, B-ultrasound, etc.), X-ray machines, nuclear magnetic resonance, etc.

Purpose of medical devices:

Medical equipment is an important symbol of modernization, the most basic element of medical, scientific research, teaching and research, and the basic condition for continuously improving the level of medical science and technology. The development of clinical disciplines depends to a large extent on the development of instruments, and even plays a decisive role. Therefore, medical equipment has become an important field of modern medicine. Medical equipment refers to instruments, equipment, appliances, materials or other items used on the human body alone or in combination, including the required software; its effects on the human body surface and body are not obtained by pharmacological, immunological or metabolic means, but these means may be involved and play a certain auxiliary role; its use is intended to achieve the following intended purposes:

(i) Prevention, diagnosis, treatment, monitoring, and relief of diseases;

(ii) Diagnosis, treatment, monitoring, relief, and compensation of injuries or disabilities;

(iii) Research, substitution, and regulation of anatomical or physiological processes;

(iv) Pregnancy control.

Technical requirements for medical devices:

Power cannot be cut off in hospitals. Once a power outage occurs, it may threaten the life safety of patients. Similarly, medical equipment cannot be powered off, so medical equipment has very strict requirements for power supply specifications. Therefore, there are special specifications in the design of medical equipment batteries.

The growth of demand for medical electronic products in China is higher than the global average-the huge population base, the rapidly increasing aging population and the people's increasing health awareness, the promotion of national policies, medical informationization and technological revolution. The demand for medical electronic products in China continues to grow rapidly.

In addition, China has begun to implement the 12th Five-Year Plan, which has the following three goals for the future development of medical equipment: 1) Accelerate the development of the domestic medical equipment industry; 2) Implement a unified procurement system; 3) Domestic medical institutions should give priority to purchasing domestic medical equipment. With the gradual implementation of this medical reform plan, domestic medical equipment manufacturers have made all preparations to take advantage of this rare development opportunity to fully develop a new generation of medical equipment.

In addition to meeting internationally recognized standards, other aspects such as basic performance and whether the power supply used meets the specifications are very important, because the patient's health will be directly or indirectly affected by it. If the power supply of any electronic medical device related to patient care, clinical treatment, health monitoring, or image scanning fails to power on, loses power, or has other problems, the consequences will directly affect the patient's health, and may even cause temporary or permanent damage to the patient.

Taking laboratory instruments or diagnostic equipment as an example, once there is a problem with the power supply, medical staff will not be able to make a correct diagnosis in time, and sometimes even have to do more tests, which not only wastes time, but also increases the mental burden of medical staff and patients.

In addition, once the power supply of medical equipment fails, even if it does not immediately pose a safety problem, it will not be able to perform its basic functions. Therefore, medical equipment developers must not only plug design loopholes in the product conception stage, but also continuously manage related risks throughout the product life cycle to prevent equipment failure.

Well, the above introduction to "What are medical devices? Common types, uses and technical requirements of medical devices" is almost here. I believe that everyone should know what medical devices are after reading it!
