I-Corps: Bleed Freeze

鼻出血是耳鼻喉科最常见的急症之一。它们是非常混乱、血腥、引发焦虑的经历，如果处理得当，在家里很容易处理。世界上60%的人口，超过40亿人，在他们的有生之年将经历鼻血。流鼻血最常见于2-10岁的儿童和50-80岁的成年人。某些高危人群，如老年人，需要快速干预以止血并防止进一步的并发症。在美国，鼻出血约占急诊室(ER)就诊人数的1/200。这相当于每年到急诊室就诊超过50万人次，其中90%被安全送回家。每年因鼻出血而去急诊室就诊的医疗费用超过3.5亿美元。如果采取适当的措施，大多数鼻出血都会消失。治疗方法是在鼻部柔软的侧壁施加适当的压力，持续15至20分钟不间断，并将头部略微前移。虽然这听起来很简单，但却很难做到。在家里，孩子和老人可能很容易疲倦、忘记或不理解这些步骤。这个i-Corps团队已经开发出“出血冻结器”，这是一种简单而有效的设备，可以帮助控制儿童和成年人的鼻出血。出血冷冻将压迫、冷却和药物治疗结合在一个单一的方便设备中，可以在医院、诊所或家里使用，这些都是治疗鼻出血的主要手段。该设备尺寸可调，可对鼻子柔软的侧壁施加恒定的免提压力，结合冷却功能帮助收缩血管，增加非处方药以进一步控制出血，并设计为在适当的时间内对鼻子施加足够的压力。出血冻结为三个不同的客户群提供价值：医疗提供者、学校/运动医学专业人员和父母、护理人员或经常流鼻血的个人。它通过减少在繁忙的临床环境中有效治疗患者所需的时间和资源，对医疗提供者来说是有价值的。对于需要获得简单易用的鼻出血治疗的教练、培训师和学校护士来说，这是很有用的。S说，即使在家里，父母和老年人也可以从止血冷冻舒适且廉价的鼻血解决方案中受益，这种解决方案可以减少或消除昂贵的急诊室或医生办公室。出血冻结有可能成为鼻血救援的家喻户晓的名字。

Nosebleeds are one of the most common ear, nose, and throat emergencies. They are very messy, bloody, anxiety provoking experiences that could be easily managed at home if treated appropriately. Sixty percent of the world population, over 4 billion people, will experience a nosebleed in their lifetime. Nosebleeds are most common in children 2-10 years old and adults 50-80 years old. Certain high-risk groups, such as the elderly, require rapid intervention to stem bleeding and prevent further complications. In the United States, nosebleeds account for approximately 1 in 200 emergency room (ER) visits. This amounts to over 500,000 visits to the ER annually, 90% of which are safely sent home. ER visits for nosebleeds are responsible for an annual healthcare cost of more than $350,000,000. Most nosebleeds will resolve if the proper steps are taken. They should be treated by applying appropriate pressure to the soft side walls of the nose, for 15 to 20 minutes without interruption, and positioning the head slightly forward. While this sounds simple, it is hard to do. At home children and elderly may easily tire, forget, or not understand these steps. This I-Corps team has developed the "Bleed Freeze," a simple and effective device to help control nosebleeds in children and adults. Bleed Freeze combines compression, cooling, and medication - the mainstays of treating nosebleeds, into a single convenient device that can be used in hospitals, clinics or at home. The device comes in adjustable sizes and applies constant hands-free pressure to the soft side walls of the nose, incorporates cooling to help constrict vessels, adds an over the counter medication to further control bleeding, and is designed to apply adequate pressure to the nose for the appropriate amount of time. Bleed Freeze provides value to three different customer segments: medical providers, schools/sports medicine professionals and parents, caretakers or individuals who suffer from frequent nosebleeds. It is valuable to medical providers by reducing the time and resources needed to effectively treat their patients in busy clinical settings. It is useful for coaches, trainers and school nurses who need access to easy-to-use nosebleed treatment. Even at home, parents and elderly can benefit from Bleed Freeze's comfortable and inexpensive solution to nosebleeds which can reduce or eliminate costly visits to the emergency room or doctor?s office. Bleed Freeze has the potential to become a household name for nosebleed rescue.
