　　Introduction to the Role of Pumps in Medical Devices

　　Small compression and vacuum pumps are essential components in many medical devices, especially those used in medical aesthetics, healthcare, and therapeutic treatments. These pumps are employed to apply controlled pressure, either continuously or intermittently, based on the specific medical application. A key requirement in the medical field is the reliability of these pumps. To meet the stringent quality demands, opting for silent, long-lasting brushless pumps becomes crucial.

　　But what sets Shenzhen Jingsuguang Technology Co., Ltd.¨s miniature pumps apart in the medical device market? Below, we will explore various medical applications of these pumps. First, let¨s understand how small compression and vacuum pumps are integrated into medical equipment.

　　Small Pneumatic Compression Pumps for Shockwave Therapy Machines

　　Shockwave Therapy, or ESWT, is a non-invasive treatment designed to accelerate healing and alleviate pain in damaged tissues. By employing focused sound energy, this therapy stimulates deep tissue repair in a short time frame. Shockwave machines are equipped with a projectile enclosed within a tube, and a compression pump provides the necessary compressed air to propel this projectile. When it strikes the applicator head, the energy is transformed into pressure waves.

　　These waves penetrate tissues, promoting faster recovery than conventional massages. For joint and deep tissue issues, focused shockwave therapy, which employs piezoceramic stones, can be especially effective. Medical specialists such as podiatrists increasingly utilize these devices, which rely on high-efficiency, durable miniature compressor pumps.

　　Compact Vacuum Pumps for Portable Vacuum Therapy

　　Micro vacuum pumps, such as those provided by Shenzhen Jingsuguang Technology Co., Ltd., are critical in treating conditions like erectile dysfunction (ED). These pumps create a vacuum around the affected area, stimulating blood flow and promoting an erection. By removing air from a tube, these pumps create the necessary pressure differential to improve circulation.

　　It is essential for users to ensure their selected vacuum pump has a built-in limiter to prevent excessive pressure buildup, which could be harmful. Our micro vacuum pumps for portable therapy systems are designed with user safety and performance in mind.

　　Negative Pressure Pumps for Wound Therapy

　　Negative pressure wound therapy (NPWT) relies on specialized pumps to draw out fluid and infection from wounds, accelerating healing. These devices apply controlled vacuum pressure through a dressing, helping improve blood flow around the wound. Our mini pumps are engineered to deliver the precise pressure necessary for various wound types and healing requirements, contributing to faster recovery.

　　Shenzhen Jingsuguang¨s pumps can operate in either intermittent or continuous modes, providing versatility for different treatment plans.

　　Pneumatic Compression in Pressotherapy and Compression Therapy

　　Pressotherapy is a widely used treatment for enhancing lymphatic drainage and supporting detoxification and pain relief. The procedure requires the use of compact pneumatic compression pumps to deliver continuous, regulated pressure. The multi-chamber garment is gradually inflated and deflated to encourage lymphatic movement.

　　Our pumps deliver reliable performance, ensuring effective treatment with controlled pressure that helps achieve the desired therapeutic effects, such as improved circulation and reduced swelling.

　　Micro Vacuum Pumps for Cupping Therapy

　　In vacuum cupping therapy, micro vacuum pumps create suction in specialized cups applied to the skin. This technique helps increase blood flow to targeted areas, aiding in detoxification and muscle relaxation. Advanced models use rubber pumps for greater control over vacuum pressure.

　　Our vacuum pumps are engineered to provide consistent and safe pressure, ensuring effective cupping therapy for patients while maintaining a high standard of quality and durability.

Athens, May 13 (Reporter Chen Gang) Greek Prime Minister Mitsotakis criticized on the 13th that the new President of North Macedonia Davkova’s use of Macedonia when mentioning the name of the country in his inaugural speech was inconsistent with the previous agreement reached between the two countries.

North Macedonia President-elect Davkova was sworn in on the 12th. In her inaugural speech, she used Macedonia when referring to her country’s name, causing Greek Foreign Minister Jera Petritis to leave the table on the spot.

Mizotakis said North Macedonia’s new president’s call of his name was unacceptable, violating the agreement between the two countries.

The Office of the President of North Macedonia later issued a statement saying that Davkova insisted that she had the right to use the name of Macedonia and believed that her practice was in line with European values and principles.

European Commission President Von der Leyen and European Council President Michel successively issued articles on social media pointing out Davkova’s actions were inappropriate. Von der Leyen said on social media: If North Macedonia wants to successfully join the EU, the most important thing is to continue on the path of reform and fully respect binding agreements.

Macedonia became independent from Yugoslavia in 1991 and established its constitutional name as the Republic of Macedonia. Greece believes that this name implies that it has territorial and cultural heritage requirements for the Greek province of Macedonia. Due to a name dispute, Greece, a member of the European Union and NATO, opposes the Republic of Macedonia’s accession to the European Union and NATO.

After years of mediation negotiations, the two countries reached an agreement in June 2018 to change Macedonia’s name to the Republic of North Macedonia as a condition for Greece to agree to its accession to the European Union and NATO. In January 2019, the two parliaments successively approved the agreement. In February 2019, Macedonia officially changed its name to the Republic of North Macedonia.
