Laser welding is a technology that drives the advancement of the medical device industry

In recent years, policies on the construction of medical alliances have been introduced in various provinces. This is not only a sign of the accelerated implementation of the national hierarchical diagnosis and treatment system, but also means the expansion of market demand for medical devices. China has the potential to adopt positive policies and tap into huge market potential: revenue will reach one trillion US dollars, and it has become the world's second largest market. Relevant data show that by 2023, the number of private hospitals in my country will reach 35,900, and the compound growth rate from 2019 to 2023 will be about 11.53%.

The security of information and applications in the medical and health industry is related to people's livelihood. The Party Central Committee, the State Council, and the National Health Commission attach great importance to this. In addition, national certification also provides sufficient growth space for the scientific and technological transformation and independent research and development of pharmaceutical companies, and laser welding technology has played a boosting role in the development of the medical and health industry, and the market application space is huge.

Compared with other commonly used welding processes, plastic laser welding produces almost no welding slag and debris, and no adhesive is required during the welding process, so it can fully meet the welding requirements of clean rooms. Laser welding technology has played a great role in promoting the development of medical equipment. For example:

Earwax protector:

Currently, typical ITE hearing aids are only as big as the tip of a little finger, but all hearing aids have a big problem: the ear wax (also known as cerumen) produced in the ear canal will pollute the sound output area. To ensure that the hearing aid can perform its reliable function, a protective device must be set at its sound output position, and laser technology becomes the most suitable choice at this time.

Analyzer:

Analyzers are usually equipped with special plastic parts for one-time use for blood analysis. Contour welding is usually selected. In order to absorb laser beams, when joining two different parts, they are generally on the transparent part, and the parts below have absorption ability.

Balloon catheter:

Laser welding uses the laser of the balloon catheter as an energy source, and uses infrared welding to directly shoot the laser into the plastic surface to achieve plastic melting. Through advanced laser welding technology, the seamless connection between the balloon head and the tube body is achieved, so that the balloon head can be smoothly pushed into the curved and narrow blood vessels of the diseased blood vessels, reducing vascular damage and improving surgical safety.

Dispensing System:

This system can help patients better control the dosage of medication during medication. It is smaller and easier to carry. Because it is directly applied to the patient, the hygiene requirements are very high, the microchannel diameter is >10渭m, and the weld must be completely particle-free. These requirements can be met by laser welding technology.

Microfluidic components:

With the help of the mask welding principle, microfluidic parts can be welded accurately and reliably. The geometry of the channel will remain unchanged, avoiding the molten material from entering the narrow channel of only 200渭m.

Now, with the attention of the country, the frequency of the medical device industry is increasing. There is no doubt that the medical device industry has developed from a vertical industry to a comprehensive industry that integrates the whole society, integrating the transformation of digitalization and intelligence, and has become the key to the "Internet of Everything" in the human social form. At present, in addition to applying plastic laser welding technology to medical device production, there are many innovative laser processing technologies in medical device manufacturing, such as laser surface modification, laser cutting, laser beam micro-processing, etc. We firmly believe that through sufficient research and reference, using these advanced laser processing technologies, more high-quality medical devices will be designed.
