技术领域technical field
本公开涉及一种具有偏置件的推送装置。The present disclosure relates to a pusher having a bias.
背景技术Background technique
出于临床诊断或个人健康监测的需要，有时需要将包含分析物传感器的医疗器械插入皮肤以下以检测组织液中某特定成分(例如葡萄糖、盐、乳酸、氧)的浓度。For clinical diagnosis or personal health monitoring, it is sometimes necessary to insert a medical device containing an analyte sensor under the skin to detect the concentration of a specific component (eg, glucose, salt, lactate, oxygen) in interstitial fluid.
特别地，对于糖尿病患者而言，很有必要平日实时、连续监测组织液的葡萄糖浓度，以减少和降低胰岛素依赖性的糖尿病患者的低血糖症和高血糖症等并发症的发生。通常当血液中的葡萄糖浓度开始降低时，组织液中的葡萄糖浓度比血液中的葡萄糖先出现降低，由此表明组织液中的葡萄糖浓度的降低可以为即将出现的低血糖做出预测。方便用户在平日实时地监测组织液中某特定成分的浓度的分析物监测装置通常包括插入皮肤以下与组织液接触的分析物传感器和贴敷在皮肤上的传感器控制装置。而且分析物监测装置通常放置在上臂。为了将分析物监测装置放置在合适的工作位置，通常需要借助推送装置。即推送装置需要把分析物传感器插入皮肤以下同时将传感器控制装置贴敷在皮肤上。此类推送装置通常需要用户单手操作，所以要求推送装置操作简单、安全、插入和贴敷可靠。另外，为了将分析物传感器插入皮肤以下，通常使用针尖。然而，目前市场上的此类推送装置往往操作复杂、推送力度不可控、插入过程位置偏移，分析物监测装置未被合适的插入和贴敷，导致用户体验较差和监测结果不可靠等问题。Especially, for diabetic patients, it is very necessary to monitor the glucose concentration of interstitial fluid in real time and continuously on weekdays, so as to reduce and reduce the occurrence of complications such as hypoglycemia and hyperglycemia in insulin-dependent diabetic patients. Usually, when the glucose concentration in the blood begins to decrease, the glucose concentration in the interstitial fluid decreases before the glucose concentration in the blood, thus indicating that the decrease in the glucose concentration in the interstitial fluid can make a prediction for impending hypoglycemia. An analyte monitoring device that is convenient for users to monitor the concentration of a specific component in interstitial fluid in real time usually includes an analyte sensor that is inserted under the skin and contacts the interstitial fluid and a sensor control device that is attached to the skin. Also the analyte monitoring device is usually placed on the upper arm. In order to place the analyte monitoring device in a suitable working position, it is usually necessary to use a push device. That is, the push device needs to insert the analyte sensor under the skin and stick the sensor control device on the skin at the same time. This type of push device usually needs to be operated by the user with one hand, so the push device is required to be easy to operate, safe, reliable in insertion and application. Additionally, to insert an analyte sensor below the skin, a needle tip is typically used. However, such push devices currently on the market are often complicated to operate, with uncontrollable push force, position deviation during insertion, and improper insertion and application of analyte monitoring devices, resulting in poor user experience and unreliable monitoring results. .
发明内容Contents of the invention
本公开有鉴于上述现有技术的状况而完成，其目的在于提供一种用于医疗器械的操作简单、安全、插入和贴敷可靠的推送装置。The present disclosure is made in view of the above-mentioned state of the prior art, and its purpose is to provide a push device for medical devices that is easy to operate, safe, reliable in insertion and application.
