現在壓力傳感器應用范圍非常的廣泛，它不僅應用在工業上，而且廣泛應用在醫學上。下面就來簡單介紹一下醫用壓力傳感器。
    醫用壓力傳感器是選用醫用級聚氯乙烯、聚碳酸脂作為傳感器的測壓連接管和主體的材料。它的包裝規格有CH-DPT-248、CH-DPT-248Ⅱ、CH-DPT-248Ⅲ三種。
它一般適用于檢測對人體有中心靜脈壓、創血壓如動脈壓、左冠狀動脈壓、肺動脈壓等等的壓力，它可以直接獲得血壓這個生理參數，能夠為臨床的時候對疾病的診斷、治療還有預后估計提供非常客觀的依據。
    下面介紹一下醫用壓力傳感器調零校準的知識。
1、最好把傳感器和它的三通閥放在腋中線的水平面上，三通的作用就是用來通氣還有給傳感器調零的；
2、要確認好三通閥上面的是有孔保護帽，而且要把監護儀和傳感器連接在一起，接著按照監護儀的說明書里面的內容，在大氣的條件下，把傳感器調零；
3、在監護儀調零之后，要把空氣連接口和三通閥關閉掉，接著把有孔保護帽換上無孔的保護帽；
4、需要使用方波來檢測系統的動力這個反應，而且動力反應檢測的實施應該是在管路沖洗完、氣泡排完之后，并且與病患者連接起來，還有調零校準等等的操作完成之后。
5、 當系統已經調零和校準都正常完成之后，就可以按照所需要的操作給病患者進行動態的檢測了。
    那么，醫用壓力傳感器又是如何安裝的呢？它的安裝主要分為六個步驟。
第一、在連接壓力傳感器系統之前要打開監護儀；
第二、需要通過消毒的措施來打開包裝，確保它所有的接口都是安全的密封的還有三通閥這些輔件的工作狀態都是良好的；
在這個安裝步驟中需要注意的是：在連接接頭的時候，千萬不要把它擰得太緊了。
第三、旋塞閥的全部通口都應該要蓋住有孔的保護帽，一直到傳感器系統里面裝滿了肝素生理鹽水的溶液以及把氣泡全部排完后，這才可以把有孔的保護帽換成沒有孔的保護帽；
第四、把傳感器跟監護儀連接起來，然后按照監護儀的說明書把監護儀調零；
在這個安裝步驟中需要注意以下兩點：1、在安裝DPT-248Ⅱ、CH-DPT-248Ⅲ這兩款傳感器的時候，要使用顏色編碼鑒別血壓的類型：藍色的時候是中心靜脈壓；綠色的時候是左冠狀動脈壓；黃色的時候是肺動脈壓；紅色的時候是動脈壓；而白色的時候是其他壓力；2、如果沒有辦法調零的話，就要更換傳感器，然后重新進行調零；如果調零沒有成功的話，那就需要檢查以下監護儀、電纜連線等是不是正常的。
第五、在使用肝素生理鹽水洗滌管路的時候，要同時把管路里的空氣排掉。
在這個安裝步驟中需要注意的是：管路里一定不可以帶有殘留的氣泡。
第六、等到全部管路里都充滿了肝素生理鹽水之后呢，就要把傳感器系統跟人體連接起來。
    隨著社會醫療的發展，醫用壓力傳感器在醫學上的使用會越來越廣泛的，而且對它的技術的研究也會越來越完善的。

Pressure sensors are now wide range of applications, it is not only used in industry, but also widely used in medicine. Here's a brief medical pressure sensors.
    Medical selection of medical grade pressure sensor is PVC, polycarbonate sensor manometry as a connecting pipe and the main material. It's packaging specifications CH-DPT-248, CH-DPT-248 Ⅱ, CH-DPT-248 Ⅲ three.
It generally applies to the detection of the human body have central venous pressure, invasive blood pressure, such as arterial pressure, left coronary artery pressure, pulmonary artery pressure, and so the pressure, it can be the physiological parameters of blood pressure, time to clinical diagnosis of disease, treatment There prognosis provide very objective basis.
    Here's what the pressure sensor zero calibration of medical knowledge.
1, the sensor and its best three-way valve on the axillary line of the horizontal plane, three-way function is used for ventilation, there is zero of the sensor;
2, a good three-way valve to be sure there is a hole above the protective cap, and should monitor and sensors, connected together, then follow the instructions which monitors the content of the atmosphere conditions, the sensor zero;
3, the monitor zero, the necessary air connections and the three-way valve shut off, then put a hole in the protective cap put on non-porous protective cap;
4, need to use the square-wave power to detect this reaction system, and the implementation of the dynamic response testing should be completed in the pipeline flush, drained after the bubble, and connect with patients, there is zero calibration is complete, etc. after.
5, when the system is zero and calibration are done properly, you can follow the action required to give patients a dynamic test.
    So, medical pressure sensor is how to install it? Its installation is divided into six steps.
First, the connection to open before the pressure sensor system monitor;
Second, the need to open the sterile package of measures to ensure the safety of all its interfaces are also three-way valve seal of the working status of these accessories are good;
In this installation step is to note: when the connector, do not tighten it too tight.
Third, plug all openings should be covered with protective cap hole, the sensor system has been filled with heparin saline solution and the bubble after all the rows, this can put a hole in the protective caps replace the protective cap without holes;
Fourth, the sensor with the monitor connected, and then follow the instructions to monitor the monitor zero;
In this installation steps need to pay attention to the following two points: 1, install the DPT-248 Ⅱ, CH-DPT-248 Ⅲ these two sensors when using color-coded to identify the type of blood pressure: when the blue is central venous pressure; green when the left coronary artery pressure; yellow when the pulmonary artery pressure; red when the arterial pressure; and white when the other pressure; 2, if there is no way to zero, then we would replace the sensor, and then re-zero; If zero is not successful, then it would need to check the following monitors, cables, connections, etc. is not normal.
Fifth, the use of heparin saline wash pipe when the pipe to the air while the drain.
In this installation steps that need attention are: pipe with residue inside the bubble must not.
Sixth, until all the pipes are filled with heparin in saline after that, it is imperative to connect the sensor system with the human body.
    With the development of social health, medical pressure sensors used in medicine will be more extensive, and its technology research will be more perfect.
