Design and Implementation of Quality and Safety Traceability System for Reusable Medical Devices Disinfection Based on RFID Technology / 中国医疗器械杂志

Focusing on the requirements of visual traceability for reprocessing of reused medical devices under the background of deep integration of intelligent medical treatment, a quality and safety traceability system for disinfection of reused medical devices is developed. The multi-dimensional data of the reprocessing chain of reusable medical devices are acquired in real time by the RFID mobile terminal handset and stored temporarily. The data package is formatted based on LoRa protocol and uploaded to the management and control platform in multi-threaded transmission mode for in-depth analysis and traceability. The corresponding prototype system is developed. The first-line operation and maintenance test results show that the prototype system has strong cooperation, strong operation robustness, and obvious advantages in the identification rate and other layers of sterile equipment package.

Menstrual cup: awareness among reproductive women

Background: Menstrual cup is an alternative to sanitary pads, which has received attention in relatively small-scale studies in high income, and low- and middle-income countries, including among schoolgirls. Made of high-grade medical grade silicone (biodegradable) have the advantage of reuse, and can potentially last up to 10 years. Objective of this study was to assess and analyse the awareness regarding menstrual cup among the women of reproductive age group.Methods: Data collected from the selected eligible participants by an interviewer administered study proforma. It is a descriptive cross-sectional study over 1 month in women in reproductive age in A. J. Institute Mangalore, Karnataka, India.Results: A total 82% were aware about menstrual cup but only 2.6% have used it.Conclusions: One challenge of menstruation that is taken for granted in affluent countries is the simple question of how to manage or contain the menstrual flow and what happens to a girl or woman who is not able to do this successfully. Menstrual hygiene management is therefore an increasingly important (yet often unrecognized) issue that is heavily intertwined with girls’ education, empowerment, and social development.

Microsurgical Training using Reusable Human Vessels from Discarded Tissues in Lymph Node Dissection

The use of human vessels at the beginning of microsurgery training is highly recommended. But vessels with the appropriate length for training are not often obtained. Whether these vessels may be reused for training has not been reported. Accordingly, we harvested vessels from discarded tissues in lymph node dissection and demonstrated that vascular anastomosis training using the same human vessels several times is possible by placing the vessels in a freezer and defrosting them with hot water. Vascular walls can be stored for microsurgical training until about 4 years after harvest, as shown in the gross appearance and histologic findings of our preserved vessels. We recommend the technique presented here for the long-term reuse of human vessels for microsurgery training that closely resembles real procedures.
