Embodiment Construction
[0026] The technical solutions in the embodiments of the invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of them. Based on the embodiments of the invention, all other embodiments obtained by persons of ordinary skill in the art without creative work belong to the protection scope of the invention.
[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the invention are only used to explain the relative relationship between the components in a certain posture (as shown in the drawings). Positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0028] refer to figure 1 , Figure 5 As shown, the exhaust device 10 includes a support fr...

The invention discloses an air exhaust device. The air exhaust device comprises a support framework, the support framework comprises an extruding fixed plate, the air exhaust device further comprisesan extruding movable plate arranged on the support framework, and a driving mechanism arranged on the support framework and used for driving the extruding movable plate to move towards the direction of the extruding fixed plate, a clamping cavity used for clamping an external blood bag is formed between the extruding movable plate and the extruding fixed plate, the width of the clamping cavity isgradually increased from the rear end to the front end, the rear end of the clamping cavity clamps the lower part of the blood bag, and the front end of the clamping cavity clamps the upper part of the blood bag. The invention further discloses a blood composition segregating machine adopting the air exhaust device. The driving mechanism drives the extruding movable plate for realizing air exhauston the blood bag, so that the air exhaust is more thorough and more intelligent. The width of the clamping cavity is gradually increased from the rear end to the front end, thus during the extrudingprocess, the lower part of the blood bag is extruded first, gradually, the upper part of the blood bag is extruded, therefore, air is extruded from the lower part of the blood bag to the upper part (acatheter at the opening of the blood bag) of the blood bag, and finally, a better air exhaust effect is obtained.
Description
technical field [0001] The invention relates to the technical field of fully automatic blood component preparation, in particular to an exhaust device and a blood component separator using the exhaust device. Background technique [0002] After being separated by a centrifuge, the blood in the whole blood bag will be separated into layers, the upper layer is the plasma layer, the middle is the buffy coat layer (platelets, a very small, very thin layer), and the lower layer is the red blood cell layer. The blood component separator is used to divide a bag of blood into several small bags of blood or to separate the various components after the centrifuge. The separation process: hang the whole blood bag on the front side of the blood component separator, and squeeze it to move The plate squeezes the plasma layer (or buffy coat) on the blood bag to make it enter the empty collection bag along the catheter to achieve the purpose of component separation. The blood components ar...
