Embodiment Construction

[0014] The present invention will be explained and described below in conjunction with a specific embodiment of the present invention.

[0015] The device provided by the present invention is mainly used in a fully automatic blood component separator. The technical problem to be solved is to squeeze the maintenance liquid into the blood collection bag that has completed plasma separation to resuspend the remaining red blood cells in the blood collection bag, and obtain the red blood cell suspension. Finally, in the process of quantitatively distributing the red blood cell suspension again, real-time monitoring of the weight of the red blood cell suspension squeezed into the empty maintenance solution bag that has been squeezed out of the maintenance solution is realized.

[0016] Such as figure 1 As shown, the present invention is provided with a slope-shaped top extrusion plate 1, and the top extrusion plate 1 is connected with a connecting rod 98, and the connecting rod 98 p...

Abstract

The invention discloses an extruding and weighing device of a full-automatic blood component separator. The extruding and weighing device comprises a supporting plate, a cylinder positioned below the supporting plate, a transverse z-shaped ejector rod pushed by the cylinder to move up and down, a connecting block arranged above the supporting plate, a weighing sensor, a maintenance solution holding plate and a top extruding plate, the weighing sensor, the maintenance solution holding plate and the top extruding plate are connected with the connecting block, and the maintenance solution holding plate and the weighing sensor are connected and fixed in a proper manner; when the transverse z-shaped ejector rod is driven by the cylinder to move downward, the top extruding plate extrudes a maintenance solution bag placed on the maintenance solution holding plate, and one end, fixed to the connecting block, of the weighing sensor is not supported by the z-shaped ejector rod, so that a weighing function is not realized; when being pushed by the cylinder to move upward, the transverse z-shaped ejector rod penetrates the supporting plate from bottom to top to jack up the connecting block, the weighing sensor and the maintenance solution holding plate, and the weighing sensor is supported by the connecting block to realize the weighing function so as to weigh the maintenance solution bag placed on the maintenance solution holding plate.

Description

technical field [0001] The invention relates to a device for the separation process of blood components, and is especially suitable for a device with maintenance fluid extrusion and weighing functions on an automatic blood component separation machine. Background technique [0002] The current mainstream automatic blood component separation machine adopts the process for blood component separation: the blood collection bag is squeezed by the front side extrusion plate of the automatic blood component separation machine and centrifuged, and the upper plasma in the blood collection bag is squeezed into the plasma collection bag to complete. Separation of plasma and red blood cells, and then squeeze the maintenance solution bag placed on the front baffle of the component separator through the front extrusion plate of the automatic blood component separator, and transfer the maintenance solution in it to complete the plasma separation and only the remaining Red blood cell bag in...
