Brook Life-Saving Airway in Case This is a Brook Life-Saving Airway device in case. The rectangular clear plastic case has white and red writing that reads: "The Brook Life-Saving Airway for mouth-to-mouth artificial respiration without oral contact with the Brook non-return valve. T.M/ Reg. Professional Model No 900 for professional and trained first-aiders on victims over 9 years of age. Distributed by (missing label). Instructions enclosed. GHWood." Inside, the airway device is contained within plastic packaging. It features a rigid clear plastic non-return valve and tube, and a curved soft mouthpiece of clear plastic. There are also two leaflets: one rectangular, book-folded, blue with white ink, showing images and instructions on how to insert and use the airway in English, Spanish, French, and German. The other leaflet is an A4 pounched paper, folded as a leaflet. It has an image of an individual using the airway device on another person on one side and features feedback from various doctors who used it since its introduction in 1959 on the other. This side also shows images of the two models, 400 and 900. The model 400 is smaller and was designed for general use and for victims of all ages. The back of the plastic case has residue of glue, which covered the two adhesives provided by the manufacturer for wall mounting. This indicates that the case was mounted vertically, so that in case of emergency, the operator would remove the push-fit lid and use the instrument, as reported by a second rectangular blue paper leaflet with white ink images. The device was designed to be washed with water and soap and not meant to be sterilized in an autoclave, but rather with a sterilizing cold solution, as indicated in the leaflet. It is named after its inventor, Dr. Morris Brook, who developed it in 1957. He had the idea after providing mouth-to-mouth resuscitation to a miner, inspired by the need for a more hygienic method. Designed to clip onto a miner’s helmet, it ensured quick access in emergencies. However, from the 1980s, newer devices made it obsolete, but it was a crucial step in modern lifesaving techniques. Indeed, mouth-to-mouth resuscitation was reintroduced and endorsed by the American Medical Association in 1958, and combined with chest compressions to form CPR by 1962. 1950-1999
