What are the medical devices? Common types, uses and technical requirements of medical devices

People who work in hospitals always deal with all kinds of medical equipment, but this is normal, 

after all, the work must be good first, with medical equipment to better treat patients. What are 

the medical devices? Today, Xiaobian network will tell you in detail, and introduce the common 

types and uses of medical devices and technical requirements, let's hurry to listen to it!

What are the medical devices?

The medical devices in the hospital can be divided into three categories, namely diagnostic and 

therapeutic categories and the different requirements of different levels of necessary medical 

devices.

First, diagnostic equipment can be divided into the following categories:

Physical diagnostic instruments (thermometer, sphygmomanometer, microscope, audiometer, 

various physiological recorders, etc.), imaging (X-ray machine, CT scan, magnetic resonance, 

B-ultrasound, etc.), analytical instruments (various types of counters, biochemical, immunoanalytical 

instruments, etc.), electrophysiological (such as electrocardiograph, electroencephalogram machine, 

electromyogram machine, etc.).

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

Common surgical instruments, optical surgical instruments (fiber endoscopes, laser therapy machines, 

etc.); Auxiliary surgical instruments (such as various anesthesia machines, ventilators, extracorporeal 

circulation, etc.); Radiotherapy machinery (such as deep X-ray therapy machine, cobalt-60 therapy 

machine, accelerator, gamma knife, various isotope therapy equipment, etc.); Other categories 

(microwave, hyperbaric oxygen, etc.).

Third, the level requirements of the necessary medical devices in the hospital can be divided into three 

categories:

Category I, Category II and Category III. That is, the first category refers to medical devices that are 

sufficient to ensure their safety and effectiveness through routine management; The second category 

refers to medical devices whose safety and effectiveness should be controlled; The third category refers 

to the implantation of human body, used to support and maintain life; Medical devices that are 

potentiallydangerous 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 the medical device is Class II. 

If a medical device contains Class II and Class III, then the medical device belongs to Class III. And so on, 

we can all come to the same conclusion.

Home a variety of simple medical devices, such as thermometers, stethoscopes, sphygmomanometers, 

etc., with the development of electronic technology, automatic, semi-automatic electronic home medical 

devices such as electronic sphygmomanometers, blood glucose testers, electronic thermometers and so 

on have been marketed.

Common types of medical devices:

Home health care equipment:

Pain massage equipment, home health self-testing equipment, blood pressure monitor, electronic 

thermometer, multifunctional therapy instrument, laser therapy instrument, blood glucose meter, 

diabetes therapy instrument, vision improvement equipment, sleep improvement equipment, oral 

health products, home emergency treatment products.

Home massage products:

Electric massage chair/bed, massage stick, massage hammer, massage pillow, massage cushion, 

massage belt, blood circulation machine, foot bath, foot massager, handheld massager, Jacuzzi, 

fat belt, treatment instrument, foot therapy instrument, weight loss belt, car cushion, kneading 

pad, massage chair, breast enhancement device, beauty massager.

Home medical rehabilitation equipment:

Home cervical and lumbar retractor, traction chair, physiotherapy instrument, sleep instrument, 

massage instrument, functional chair, functional bed, support device, medical air cushion, oxygen 

generator, medicine cooker, hearing aid, etc.

Home nursing equipment: home rehabilitation nursing AIDS, female pregnancy and baby care 

products, family support gas equipment, oxygen bottles, oxygen bags, home emergency medicine 

kits, blood pressure monitors, blood glucose meters, nursing beds.

New medical devices:

With the development of science and technology, the scientific and technological achievements 

of some colleges and universities have also been rapidly transformed into results. Some patented 

products produced by new manufacturers are also appearing in the market. It includes equipment 

commonly used in homes and hospitals, such as medical trauma vehicles.

Commonly used medical equipment in hospitals:

Trauma treatment cart, operating bed, operating lamp, monitor, anesthesia machine, ventilator, 

blood cell analyzer, differentiation analyzer, enzyme marker, plate washing machine, urine analyzer,

ultrasound (color ultrasound, B ultrasound, etc.), X-ray machine, nuclear magnetic resonance, etc.

Uses of medical devices:

Medical equipment is an important symbol of the degree of modernization, is the most basic element 

of medical treatment, scientific research, teaching and research, teaching work, but also the basic 

condition for constantly improving the level of medical science and technology. The development 

of clinical disciplines depends largely on the development of instruments, and even plays a decisive 

role. Therefore, medical equipment has become an important field of modern medical treatment. 

Medical equipment means instruments, equipment, appliances, materials or other articles used on 

the human body alone or in combination, including required software; Its effects on the body surface 

and in vivo are not obtained by pharmacological, immunological or metabolic means, but these means 

may participate in and play a certain auxiliary role; Its use is intended to achieve the following intended 

purposes:

(1) the prevention, diagnosis, treatment, monitoring and remission of diseases;

(2) diagnosis, treatment, monitoring, mitigation and compensation of injury or disability;

(3) The study, substitution or regulation of anatomical or physiological processes;

(4) Pregnancy control.

Technical requirements for medical devices:

The hospital is not allowed to power off, once the problem of power failure, it may threaten the safety 

of the patient's life. Similarly, medical equipment can not be powered off, so medical equipment has 

very strict requirements for the specifications of the power supply. Therefore, there are special specifications 

in the design of medical device batteries.

China's demand for medical electronic products is growing faster than the global average - a huge population 

base and a rapidly increasing aging population and people's increasing health awareness, driven by national 

policies, medical informatization and technological revolution. The market demand for medical electronic 

products in China continues to grow rapidly.

In addition, China began to implement the 12th Five-Year Plan, in which the future development of medical 

equipment, there are the following three goals: 1) accelerate the development of domestic medical 

equipment industry; 2) Implement a unified procurement system; 3) Domestic medical institutions should 

give priority to the purchase of domestic medical equipment. With the gradual implementation of this 

medical reform program, domestic medical equipment manufacturers have made all preparations to take 

advantage of this rare development opportunity to develop a new generation of medical equipment. In 

addition to the medical equipment must meet the 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 

equipment related to patient care, clinical treatment, health monitoring, or image scanning fails to power on, 

power out, or other aspects of the problem, the consequences may directly affect the health of the patient, or 

even cause temporary or permanent harm 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 several 

tests, which is a waste of time, but also increase the mental burden of medical staff and patients.

In addition, once the power supply of a medical device fails, even if it does not pose an immediate safety problem, 

it will not be able to perform its basic functions, so medical device developers not only have to plug design 

loopholes at the idea stage of the product, but also have to continuously manage the risks throughout the life 

cycle of the product to avoid equipment failure.

Ok, what are the above medical devices? The common types and uses of medical devices and technical requirements 

of the relevant introduction, Xiaobian I almost said here, I believe that everyone should know what medical 

equipment after reading it!
