衛生福利部桃園醫院胸腔內科與台北榮總胸腔部的研究團隊合作進行了一項的研究，發現長新冠患者持續性呼吸困難及疲倦的新機轉。研究顯示，超過5成的長新冠患者在康復8個月後仍持續出現肺部過度充氣和小氣管功能受損，藉此研究提供了未來醫療新的方向。

研究團隊由桃醫胸腔內科醫師羅柏鈞、台北榮總胸腔部教授彭殿王、主任柯信國和桃醫內科部長李世偉通同完成，研究成果於今年5月在國際知名學術期刊《Respiratory Research》上發表。

研究團隊觀察，雖然國外研究顯示大部分長新冠症狀在一年內會緩解，但呼吸困難和疲倦的症狀往往持續存在。這次的前瞻性觀察研究調查了靜態肺過度充氣、小氣管功能障礙與長新冠患者持續性呼吸道症狀之間的關聯。

The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.

Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.

This antenna's operating frequency has recently been increased to 60 GHz. The research process for the product line is still ongoing but is planned to be completed this year. To receive the most recent price and technical information on the new product, please contact us for more information.

Double Ridged Horn Antennas are suitable for both transmitting and receiving purposes, with applications:

• - Antenna measurement
• - Communication systems
• - Satellite tracking systems
• - Radar Detection System
• - Surveillance System
• - Electromagnetic Compatibility Testing (EMC test)

Recommended Accessories

• - Antenna Tripod: easy and fast-changing position. 100% stable after installing.
• - SMA Cable: High-quality special SMA cable

SUMMARY TABLE OF DOUBLE-RIDGED HORN ANTENNA (HA-SERIES) 

研究結果顯示，超過五成的長新冠患者在康復八個月後仍持續出現肺部過度充氣和小氣管功能受損，這些患者更容易出現呼吸困難和疲勞。羅柏鈞表示，這項研究突顯了肺部過度充氣對新冠肺炎患者的潛在長期影響，為未來治療長新冠提供了新的方向。

李世偉指出，長新冠的機轉非常複雜，此次發現為未來治療提供了新的可能性。雖然目前已有藥物可治療小氣管功能受損，但仍需後續臨床研究來確認是否能改善長新冠症狀。未來，研究團隊計畫進一步深入探討長新冠患者持續肺過度充氣和小呼吸道受損的機轉。
