The surface design and reliability of medical devices are always one of the bottlenecks of industrial application. Vacuum technology has great advantages in the surface modification of medical devices (such as dental implants, cardiovascular stents, etc.). Compared with other conventional methods (such as sol gel, microarc oxidation, etc.), the vacuum method is very clean and can be closed-loop control without the influence of the external environment. This paper discusses the application value of the oil-free vacuum pump in medical devices, especially from the characteristics of the oil-free vacuum pump.

 The medical device industry involves medicine, machinery, electronics, plastics and other industries. It is a multi-disciplinary, knowledge-intensive and capital-intensive high-tech industry. As an important part of the pharmaceutical industry, medical devices for consumers, the configuration of medical machinery in medical institutions is second only to the standard used to judge medical institutions.

Compared with the oil pump, the oil-free vacuum pump has low vacuum, small gas extraction, but simple structure, small size, easy to install, simple maintenance, easy movement, does not produce lampblack, do not pollute the environment, especially in the higher requirements of the laboratory use is better. And good durability, is vacuum, compression vacuum pump, is also one of the most available equipment in the laboratory.

 Oil-free vacuum pump can be used in the following work:

1. The vacuum suction on the automatic packaging line opens the bag and packing.

2. Paper vacuum suction on the printing machine.

3. High efficiency vacuum filling of various liquids into the bottle.

4, all kinds of plastic products of the vacuum suction molding forming.

5. Air tightness test of the object surface in the vacuum state.

6, the carton and bottle of the standard is empty suction paste.

7, the photographic plate under the vacuum suction fixation.

8. Guide the gas analysis by using the pressure difference under the vacuum state.

9, the use of various pharmaceutical machinery automatic line.

10. A vacuum suction cup clamp for non-magnetic parts.

11. Leak detection test of various containers in the vacuum state.

12, food processing machinery on the application.

13, Chinese and Western medicine factory vacuum distillation and drying.

14. Vacuum attraction in the hospital operating room.

15, universities, research institute, factory and mine laboratory gas analysis, physical and chemical experiments.

16. The supporting use of various medical instruments, etc.

 Surface engineering technology plays a very important role in the design, manufacture and use of medical devices. The performance of a medical device mainly depends mainly on its composition and its microorganization. Most medical devices receive surface modification technology due to failure or failure due to surface related friction wear, corrosion oxidation and fatigue fracture.

Several methods of surface modification of medical devices using vacuum technology, especially plasma oxidation, carbon-based film preparation and electron beam evaporation, are listed.

1. The preparation of hydrophilic titanium oxide surface by plasma oxidation helps to promote the adhesion and proliferation of osteoblasts, and provides the possibility to shorten the healing time of medical implants;

2. The preparation of carbon-based film can enhance the pretension force of the implant system, and improve its long-term success rate and reliability;

3. Electron beam evaporation and other technologies provide feasible solutions to solve the problems of cardiovascular stent restenosis and long-term success rate. Because the vacuum technology can provide cleaner and more effective surfaces for medical devices, they can better meet the clinical needs.

By analyzing the application value of oil-free vacuum pump in medical devices, the results show that the surface prepared by vacuum technology has excellent wetting characteristics, which can control the adsorption and expansion of cells and improve the behavior of implants after implantation. Therefore, the vacuum technology is an effective method to improve the therapeutic effect of medical devices, and it has an important application value in the surface design of medical devices.https://www.taixingpump.com/screw-vacuum-pump
