Leakage detecting device and leakage detecting method for blood cell separating bag

Abstract

The invention provides a leakage detecting device and a leakage detecting method for a blood cell separating bag. The leakage detecting device comprises a clamp outer wall, a clamp inner wall and a base plate. The clamp outer wall and the clamp inner wall are fixedly connected with the same side of the base plate. Furthermore an interlayer space between the clamp outer wall and the clamp inner wall forms an annular accommodating trough. The clamp inner wall is provided with a first bayonet and a second bayonet. The leakage detecting method is performed through the leakage detecting device and comprises the steps of firstly, mounting the to-be-detected blood cell separating bag on the leakage detecting device; then, only keeping one hose leading-out opening of the blood cell separating bag unclosed, integrally placing the leakage detecting device and the blood cell separating bag into a water trough; and finally, inputting compressed air into the blood cell separating bag from the reserved hose leading-out opening of the blood cell separating bag, and observing whether air bubbles overflow in the water trough. By means of the leakage detecting device and the leakage detecting method, leakage detection of the blood cell separating bag can be quickly finished. Furthermore the leakage detecting device and the leakage detecting method have remarkable advantages of easy operation, high leakage detecting efficiency, reliable leakage detecting result, etc.

Description

technical field [0001] The invention relates to the technical field of leak detection of blood cell separation bags, in particular to a leak detection device and method for blood cell separation bags. Background technique [0002] Common blood cell separation bags such as figure 1 As shown, the first hose connection plate 2 and the second hose connection plate 7 are respectively connected to the two ends of the separation bag body 3, the first hose connection plate 2 is connected to the first hose 1, and the second hose connection plate 2 is connected to the first hose connection plate 2. The hose connection plate 7 is connected to the second hose 4 , the third hose 5 and the fourth hose 6 . [0003] During the blood cell collection operation, the blood cell separation bag is installed in the centrifuge compartment of the bag-type blood cell separator, and is connected with the monitoring system and the collection system of the bag-type blood cell separator. In the centrif...

Problems solved by technology

However, during the centrifugation process, the blood cell separation bag is squeezed by the blood in the bag, and it is easy to cause bad situations such as bag breakage, which leads to waste of blood cell separation products and blood sources.

When the blood cell separation bag breaks and other adverse conditions, is it because the blood cell separation bag has broken bags and other adverse conditions before the separation operation? Or unfavorable conditions such as broken bags produced during the separation operation of the blood cell separation bag? It will be difficult to make an accurate judgment
