Because the opposing one side of two dull and stereotyped openings does not have limited block,, utilize elastomer to limit gap between flat board and the box body by the elastomer support fixation, promptly two dull and stereotyped openings are free shape, distance therebetween is active, and is variable big, the fixed bit of two flat boards under free state when its minima is making, in case put into transfusion bag, the elastomer distortion, two dull and stereotyped spacings increase, and the elastomer of distortion is exerted pressure to transfusion bag, the infusion process steady and smooth, resistance is little.

The purpose of this utility model can also realize by following approach.

Two dull and stereotyped tail ends are hinged to one, two dull and stereotyped tail end closures, put into transfusion bag like this after, dull and stereotyped opening opens, and is horizontal V font, whole infusion process from after push liquid forward, until finishing transfusion.

Or the elastomeric elastic force of tail end is greater than opening, put into transfusion bag like this after two dull and stereotyped tail ends distortion little, the opening distortion is big, it is horn-like to be level, whole infusion process liquid flow trend from after squeeze forward, until finishing transfusion.

Gapped between the inwall of elastomer and box opening end in the vertical, this gap is generally greater than 1 centimetre.Can make opening soft more like this.

By increasing elastomeric quantity and their arrangement of adjustment, dull and stereotyped extruding force to transfusion bag is distributed rationally evenly.

Generally be fixed with a plurality of elastomers in the vertical and transversely, and a plurality of elastomer height in the vertical also can be different, reduced gradually by tail end to opening.

Elastomer is elastic such as compression spring, torsion spring and latch plate, and it is the most practical wherein to compress spring.

Opening at box body has an elasticity lockset, this elasticity lockset is reached with the vertical locking plate of lock by button, lock to be formed, button is connected with locking plate, inboard at button is fixed with return spring, the locked groove that matches with locking plate is arranged on the lock, and the upper end of lock is coniform, plays the guide-localization effect, button covers on box body, and there is lockhole with matching the corresponding position of lock on box body.

Have two observer bracket holes in the side of box body loam cake, the observer support takes the shape of the letter U, and horizontal fixed has two pairs of symmetric bayonet sockets on it is vertical between the observer bracket holes, and head exposes the observer bracket holes.

Adding external force during use shrinks with its dial-out the observer support.

Advantage of the present utility model is that processing technology is simple, and cost is low, and is easy to use, the infusion process steady and smooth, resistance is little, whole infusion process liquid flow trend from after forward the extruding, until finishing transfusion, because its infusion process is an extruded type, blood back with the location independent of transfusion bag, can not put arbitrarily, need not to replenish air, also with regard to need not to worry transfusion finish after air admission blood vessel and produce danger.
