Removable detection card for in-vitro medical diagnosis device and control method thereof

Abstract

The invention provides a removable detection card for an in-vitro medical diagnosis device, the removable detection card at least comprises an internal liquid path, a blood gas detection area, a hemoglobin and hemoglobin derivative detection area, a liquid path control area and a waste liquid area, the blood gas detection area and the hemoglobin and hemoglobin derivative detection area are distributed in different liquid paths, according to switching control of the liquid path control area on the internal liquid path of the removable detection card, the same blood sample or different blood samples can enter the blood gas detection area or the hemoglobin and hemoglobin derivative detection area, so that the use cost of the detection card is reduced, and the calibration precision of the detection card can be ensured; liquid path switching is achieved through the liquid path control area in the detection card, the same blood sample can be used for completing detection of blood gas and hemoglobin indexes in one detection card, the detection blood amount of a patient is greatly reduced, the treatment cost is reduced, and the detection precision is ensured.

Description

technical field [0001] The present invention relates to the field of in vitro technology, and in particular, to a test card used in an in vitro medical diagnostic device and a control method thereof. Background technique [0002] The determination of gas components in blood is important in various scientific researches and practical applications. In the rescue of critically ill patients in clinical medicine, rapid and continuous determination of blood carbon dioxide partial pressure is crucial. Especially for mechanically ventilated patients, the partial pressure of carbon dioxide in blood is a very key indicator to determine the breathing state of the patient. The parameters of the ventilator are mainly set according to the partial pressure of carbon dioxide in the patient's blood. At present, the most widely used blood gas component detector in medicine is a blood gas analyzer. However, conventional blood gas analyzers have defects such as the need to collect a large numb...

However, misuse by personnel handling samples can lead to contamination of surfaces, spillage of samples, or damage to diagnostic devices resulting in increased repair and maintenance costs

[0005] At the same time, in the in vitro diagnostic equipment of the prior art, if only one test card is used to detect the patient's blood, or only the blood gas test can be completed, or only the hemoglobin test can be completed. , it is often necessary to take two copies of the patient's blood, which is usually not a big problem for healthy adults, but for newborns with less blood or patients with blood diseases (such as anemia), it may bring various complications to the patient. Inconvenient, at the same time, even for healthy adults, if you need to test blood gas and hemoglobin indicators at the same time, you need to use two test cards, which greatly increases the diagnosis cost of the patient and may cause a waste of resources. Therefore, it is very It is necessary to design a removable test card for in vitro medical diagnostic devices, which can complete the detection of blood gas and hemoglobin indicators in one test card. It is more ideal to use the same blood sample in one test card. Complete the detection of blood gas and hemoglobin indicators within

[0006] At the same time, in the existing design technology, before the detection card is used, it is usually necessary to calibrate the sensor in the detection card. Therefore, in order to save costs, the designer usually stores the calibration solution required for calibration in the inside the detection card, but the ensuing problem is that if the calibration solution is stored inside the detection card, in order to ensure that the calibration solution will not be affected by environmental factors such as harsh temperature and humidity, the detection card must be stored during transportation and storage. Among them, the storage conditions and environmental requirements of the detection card are relatively high, so as to prevent the calibration liquid inside the detection card from being affected, thereby affecting the calibration of the detection card sensor
