Blood filter device

The present invention relates to a blood filtering device, and more particularly to a blood filtering device having a teardrop type flow channel function.

In general, blood is responsible for the important work of oxygen and energy transfer in living organisms, and is one of the indispensable elements for the normal operation of living systems. Blood transfusion is one of the first aid measures when the body suffers from a lot of blood loss. For some patients, such as patients with special blood diseases, cancer patients receiving chemotherapy, or patients receiving bone marrow transplantation, the number of blood transfusions is even more Far higher than the average person. Based on this, various blood-centered application technologies have been developed in the field of clinical treatment and medical examination. It is hoped that the cells or substances contained in the blood can be accurately and quickly obtained to further solve the problem caused by the disease. Appropriate, improve the quality of human life. However, although blood transfusion can increase the chances of saving lives, patients who receive blood transfusions often have adverse reactions due to blood transfusions. The cause of these adverse reactions is often because the recipients also accept white blood cells in the blood of the donors. The recipient receives a transfusion reaction that is chilly or feverish. Under this concept, blood separation or filtration technology, which is the basis of many advanced applications, has been regarded as one of the key development projects. In order to solve the above problems, at present, the hospital will use the white blood cell filter to filter out white blood cells and then input the blood into the recipient's body before the bedside or before entering the blood bank inventory according to the needs of the patient.

At present, it is known that techniques for separating blood cells and plasma can be mainly classified into several categories. The first type is a centrifugal technique, in which the blood cells are placed in a test tube through the characteristics of a large proportion of blood cells, and the centrifugal force generated by the high-speed rotation is achieved to achieve the goal of separating blood cells from plasma. However, because the density and deposition rate of some blood cells are very close to, or even overlapping with, the plasma components, centrifugation techniques do not provide the required purity for certain applications. Moreover, this technology usually consumes a large amount of samples and medicines, and the processing takes a long time, and the overall cost is high. Deep filtration is a common method used in the separation of blood cells and plasma technology, and it is circulated in the vertical direction by driving blood. The layer film structure allows solid matter such as blood cells to be trapped on the surface of the film. However, the biggest problem with this technique is the formation of filter cake on the surface of the film, especially as the amount of blood introduced increases, the thickness of the filter cake will inevitably increase, so that it must be rinsed and removed every time it is used, which is quite expensive. More manpower. In addition, more importantly, deep filtration tends to exert greater pressure on blood cells in the blood, causing hemolysis during the filtration process, resulting in failure of the separation operation.

In addition, because the traditional white blood cell filter is too expensive and the filtering effect is limited, it cannot be fully popularized, which will result in the decline of medical quality and the harm of life. Therefore, how to provide a liquid filtering device with low equipment cost and simple structure, which not only has a rapid response, but also requires a small amount of sample, and the operation is economical, so that it can effectively prevent the formation of a filter cake and the phenomenon of hemolysis. The blood cell filter allows the user to obtain a blood cell filter with low cost and good filtering effect when filtering the blood cell, which should be an optimal solution.
