Methods: The technology of the double perfusion cannula accompanied with low negative pressure drainage was used to treat complexity of abdominopelvic and perineal infections. Results: Double perfusion cannula accompanied with low negative pressure drainage can be applied to the treatment of complexity of abdominopelvic and perineal infections. It has an obvious effect on infection control and reduces recovery time. Conclusion: Double perfusion cannula accompanied with low negative pressure drainage has a good effect on complexity of abdominopelvic and perineal infections; it can be used in wider surgical fields to prevent infections.展开更多

The antenna is constructed by semi-circular patch and hexagonal closed ring resonator (HCRR). For medical applications such as wireless patient movement monitoring, telemetry and telemedicine, communication devices working at ISM band frequency is needed. Here, the requirement is completed with improved directivity such as 16 dBi. And also impedance matching also achieved with low reflection loss -20 dB. This antenna works for multiple frequency bands (Industrial, Scientific and Medical-ISM 2.45 GHz, WLAN 5.3 GHz and GSM 1.9 GHz) with improved directivity.展开更多
