Component blood donation sample retention bag capable of metering and automatically closing and control method

Abstract

The invention belongs to the technical field of sample retention bags, and discloses a component blood donation sample retention bag capable of metering and automatically closing and a control method.When blood is sampled, according to specific condition, blood sampling can be performed by connecting a puncture needle or three-way union, blood samples which are obtained are conveyed to a box body, and a temperature sensor and a pressure sensor in the box body are used for detecting temperature, flow rate and pressure of the blood samples; when the blood samples passing through the box body flow past an electrically operated valve, and flow to the sample retention bag; a flower sensor is arranged in front of the sample retention bag, and is used for detecting flow rate of pumping of the blood samples; according to detection data in steps, a controller controls the electrically operated valve to adjust the flow rate; a cooler and a heater are controlled to enable the blood samples in the sample retention bag to maintain certain temperature; and the controller is used for subsequent treatment on other data obtained by detection. The component blood donation sample retention bag is convenient to use, the sample retention bag is convenient to take, the component blood donation sample retention bag has the metering effect in the process of blood retention, the working efficiency isimproved, and the component blood donation sample retention bag is safe and convenient.

Description

technical field [0001] The invention belongs to the technical field of sample retention bags, and in particular relates to a measurable and automatically closed component blood donation sample retention bag and a control method. Background technique [0002] At present, the design of the sample retention bag on the market is very inconvenient to take the sample retention bag. In addition, after the blood sample is collected, the sample retention operation needs to be performed. Therefore, when the blood collector performs blood collection and blood sampling testing, It is inconvenient to operate, thereby reducing work efficiency. Generally, the sample retention bag does not have the function of metering. After the sampling is completed, it cannot be automatically closed, and it does not have the functions of puncture and connection at the same time. [0003] To sum up, the problems existing in the prior art are: the sample retention bag does not have the function of metering...
