Description

Technical Field

[0001] The present invention relates to the field of reproductive medicine detection technology, and in particular to an intelligent monitoring and safety management system for reproductive medicine sperm collection rooms based on non-invasive sensing. Background Art

[0002] In cases of fertility or male diseases, as well as when testing semen quality before pregnancy, men need to collect sperm for analysis. This allows doctors to identify the cause of infertility (such as necrospermia, oligoasthenozoospermia, teratozoospermia, etc.) and to understand the quality of male semen before pregnancy. At this time, the patient needs to go to the semen collection room for sperm collection. Usually, medical staff will inform the patient of the semen collection process, and the patient will then go to the semen collection room on their own. For the sake of patient privacy, the patient is usually not with the medical staff, making on-site instruction almost impossible. In addition, the semen collection room is a blind spot for monitoring. Because semen collection from male patients involves privacy, medical staff are generally unable to monitor when the patient is nervous. This is especially true when the patient's heart rate is abnormal due to nervousness. Unsafe situations may occur due to lack of monitoring.

[0003] At present, most reproductive centers use the basic solution of mechanical door lock + indicator light. Some sperm collection rooms also use patients to adjust the sign by themselves to indicate whether there is someone in the room or not. If the patient forgets to adjust it after leaving, the sperm collection room will be mistakenly judged as idle. There is a lack of medical data linkage capability (the sperm collection time record is disconnected from the medical record system, and the occupancy status of the sperm collection room is difficult to control). Manual inspections have blind spots in the monitoring period, resulting in the sperm collection room being idle for too long and unable to be used by subsequent patients in a timely manner.

[0004] Existing alarm systems are passively triggered (requiring patients to actively press the emergency button); they rely on patients to actively trigger the switch (poor compliance leads to missed operations) Wearable devices such as bracelets used as monitoring devices are prone to false alarms and missed alarms. Additional devices are not conducive to sperm retrieval operations for patients, and the disinfection and cleaning of electronic wearable devices are relatively cumbersome.

[0005] Therefore, those skilled in the art have provided a non-invasive sensing-based intelligent monitoring and safety management system for sperm collection rooms in reproductive medicine to solve the problems raised in the above background technology. Summary of the Invention
