In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ Bed exit sensors notify wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

On February 24 (Tuesday), the Japan Meteorological Agency announced its three-month forecast for March to May. In the vicinity of Japan, the upper-level westerlies are expected to flow more to the north than usual, making it likely to be covered by warm air. As a result, above-average temperatures are predicted for March and April in regions excluding Okinawa and Amami, and nationwide in May. With an increase in warm days, there may also be days when it feels hot enough to sweat during the daytime. On sunny days, ultraviolet rays are likely to be strong, so please take precautions such as wearing hats and using sunscreen. For more details, please visit our website.
