Problems solved by technology

The existing white blood cell filter has a hard shell. After blood is collected by the blood station, when the blood bag and the hard shell leukocyte filter are put into the centrifuge for high-speed and strong centrifugation, the hard shell will be cracked and polluted by the outside air. The clinical use of white blood cell filters polluted by outside air will cause medical accidents. Therefore, the method of high-temperature fast connection is basically used now, that is, the blood in the blood bag is centrifuged in the component department of the blood bank. After the composition is completed, the white blood cell filter is connected to the pipeline of the blood bag through a high-temperature fast connection to filter out the white blood cell components in the blood. Although it is connected through a high-temperature fast connection, it is already Open the original blood bag closed system, so it is easy to be polluted by the outside air, causing medical accidents

Embodiment Construction

[0024] Referring to the accompanying drawings, specific embodiments of the present invention will be described.

[0025] figure 1 with figure 2 It is a cross-sectional schematic diagram of a bag-type leukocyte filter, which is composed of a leukocyte filter 1, a sealed bag 2, a tube 3, a tube 4 and a control clip 5, and is characterized in that: the leukocyte filter 1 has a filter membrane (used to remove leukocytes in the blood) ), the inlet junction pipe 3, the outlet junction pipe 4 of the leukocyte filter 1, the outer periphery of the leukocyte filter 1 has a sealing bag 2, the sealing bag 2 surrounds the leukocyte filter 1, and the sealing bag 2 is heat sealed with the tube 3 , there is a control clip 5 on the tube 3, and the bottom of the sealing bag 2 is heat sealed with the tube 4. The regulating clip 5 controls the conduction or cut-off of the pipeline. In order to prevent the regulating clip 5 from puncturing the blood bag during centrifugation, the regulating cli...

Abstract

A bagged white cell filter for blood transfusion or taking blood to remove white cell from blood is composed of bag-type white cell filter with hard casing, by-pass tube, single bag or double bag or triple bag, and the blood taking single bag or double bag or triple bag. It features that when it is strongly centrifugalized, the filter can not be polluted even if its hard casing is cracked.

Description

technical field [0001] The invention relates to a blood transfusion (collection) device used in medical equipment, more precisely a filter for removing white blood cell components in blood after blood collection from a human body. Background technique [0002] Because there are certain differences between people even with the same blood type, adverse reactions often occur during blood transfusion, and these adverse reactions basically come from the white blood cells in the blood. Therefore, the white blood cells in the blood should be removed to reduce the clinical blood transfusion. Adverse reactions. The existing white blood cell filter has a hard shell. After the blood station collects blood, when the blood bag and the hard shell leukocyte filter are put into the centrifuge for high-speed and powerful centrifugation, the hard shell will be cracked and polluted by the outside air. The clinical use of white blood cell filters polluted by outside...
