  • 我想成為醫藥行業的銷售代表。我選擇的公司是強生醫療器械公司。強生公司成立于1886年,是一家美國跨國醫療器械、藥品和消費品包裝制造商。它的普通股是道瓊斯工業平均指數(dowjonesindustrialaverage)的一個組成部分,該公司是《財富》500強之一。強生公司在2005年之前連續七年在哈里斯互動公司的全國企業聲譽調查中名列榜首,[2]2008年被《巴倫雜志》評為世界上最受尊敬的公司,[3]2005年被美國國務院授予本杰明·富蘭克林公共外交獎的第一家公司為國際教育項目提供資金。
     
    在這本雜志中,作者提到,醫生們想知道是否有一種更簡單、侵入性更小的方法來評估有睡眠問題的患者,他們現在必須在醫院或診所呆上一晚,戴著幾十個連接到昂貴電子設備的電極。美國每年進行100多萬項睡眠研究,以檢測慢性睡眠障礙。目前,這些要求患者在一家診所過夜,診所連接多達30個傳感器,從腦電波電極到血氧追蹤器。這些研究的數據被分為時間段,并在一個昂貴的過程中被人工分類為各種睡眠狀態。對此,一組學生想出了一件“睡眠感應襯衫”,病人可以在家里、自己的床上穿。這件襯衫可以記錄足夠的關于呼吸模式的數據,以提供標準方法的成本和不便的一小部分答案。
     
    在清醒、睡眠和活動狀態下對心肺參數進行動態監測可以擴大我們對健康和疾病的了解。傳感襯衫由一件集成了生理監測傳感器的T恤、一個數據采集單元(大曲)和一套基于PC的軟件組成。一些生命體征,如心電圖(ECG)、胸腔(RC)和腹部(AB)呼吸。光容積圖(PPG)。SpO2和姿勢/活動可通過襯衫獲得。生理數據存儲在microSD存儲卡中,離線分析提取心率(HR)、呼吸頻率、血氧飽和度、潮氣量(TV)、脈搏波傳導時間(pwt)、呼吸竇性心律失常(RSA)等參數。在傳感襯衫系統中,心電信號是通過有源電極采集的。PPG和ECG由一個高速16位模數轉換器以500hz采樣,用于精確的pwt計算。在呼吸感應容積描記和PPG電路中,均采用脈沖幅度調制技術進行信號調理,以降低功耗。整個系統由2節1600毫安時AA電池供電,可連續工作48小時以上,不間斷。基本性能測試表明,該系統能夠有效地采集ECU-RC和AB呼吸信號,PPG信號,提取HR等參數。呼吸頻率。SpO2和電視信號。這種先進的動態監測系統可用于家庭保健和科學研究。這一概念目前正在進行廣泛的測試,由一家總部位于波士頓的名為Rest Devices的公司進行商業化,這家公司是前學生和他們的醫學導師建立的。

    I would like to be a GO Sales Representative in the Pharmaceutical industry. The company I choose is Johnson & Johnson Medical Devices. Johnson & Johnson is a U.S multinational medical devices, pharmaceutical and consumer packaged goods manufacturer founded in 1886. Its common stock is a component of the Dow Jones Industrial Average and the company is listed among the Fortune 500. Johnson & Johnson ranked at the top of Harris Interactive's National Corporate Reputation Survey for seven consecutive years up to 2005,[2] was ranked as the world's most respected company by Barron's Magazine in 2008,[3]and was the first corporation awarded the Benjamin Franklin Award for Public Diplomacy by the U.S. State Department in 2005 for its funding of international education programs.
    In this journal, the author mentioned that Doctors wondered if there might be a simpler and less-invasive way of assessing patients with sleep problems, who must now spend a night in a hospital or clinic wearing dozens of electrodes connected to expensive electronic equipment. Over 1 million sleep studies are performed annually in the US to detect chronic sleep disorders. Currently these require a patient to spend a night in a clinic connected to up to 30 sensors, ranging from brain wave electrodes to blood oxygen trackers. Data from these studies are divided into time segments and which are manually categorized into various sleep states in a costly process. In response, a team of students came up with a “sleep sensing shirt” that patients could wear at home, in their own beds. The shirt could record enough data about breathing patterns to provide answers at a fraction of the cost — and inconvenience — of the standard approach.
    Ambulatory monitoring of cardiopulmonary parameters during wake, sleep, and activity states can expand our understanding of health and diseases. The Sensing Shirt Consists of a T-shirt with sensors integrated for physiological monitoring, a data acquisition unit (DAQU), and a set of PC-based software. A number of vital signs such as electrocardiogram (ECG), rib cage (RC) and abdominal (AB) respiration. photoplethysmogram (PPG). SpO2, and posture/activities can be acquired by the shirt. The physiological data are stored in a microSD memory card, and then analyzed offline to extract parameters such as heart rate (HR), breathing rate, SpO2, tidal volume (TV), pulse wave transit time (PWTT), and respiratory sinus arrhythmia (RSA). In the Sensing Shirt system, the ECG is acquired by means of active electrodes. PPG and ECG are sampled by one high-speed 16-bit, analog-to-digital converter at 500 Hz for precise PWTT calculation. Technique of pulse amplitude modulation is used for signal conditioning both in respiratory inductive plethysmography and PPG circuits to reduce the power consumption. Powered by 2 AA batteries with 1600 mAh capacity, the whole system can work more than 48 h continuously without interruption. Basic performance tests demonstrate that prototypes of this system can capture ECU RC and AB respiration, and PPG signals effectively, and extract parameters such as HR. breathing rate. SpO2, and TV accurately. This advanced ambulatory monitoring system may be used in both home healthcare and scientific research. That concept is now undergoing extensive testing, on its way to commercialization by a Boston-based company, called Rest Devices, that former students and their medical mentor have set up.
