Description
Technical field
The present invention relates to be housed in the blow-molded plastic infusion container of the transfusion used in the drop treatment etc. or glucose etc.
Background technology
As plastic infusion vessel, the container of the known in the past plastic bottle type that the container of the bag type that is formed by plastic sheet is arranged and form by jetting.
The infusion vessel of bottle type has can make the axial advantage of infusion vessel.But the infusion vessel of the type forms owing to being shaped by winding-up, thus aspect flexible, have problem, thereby, owing to container when the outflow of medicinal liquid flattens fully, so have the residual shortcoming of the medicinal liquid of sizable amount.So, in the past with medicinal liquid during with the transfusion of certain flow, adopt in the thromboembolism that for example pneumatic needle is punctured to container finish and make container inside and outside connection, cooperate the outflow of medicinal liquid and import the method for air or in order to reduce debris the container capacity conservatively fill medicinal liquid, increase the method for the amount of gases such as air in advance.
But the method that pneumatic needle is punctured in the thromboembolism of container finish not only spends time in the operation of puncture pneumatic needle, and needs prudent operation so that deleterious antibacterial can not sneaked into, and is inconvenient in operation.In addition, the space that the method for the amount of the gas of increase air etc. need guarantee to fill air, having correspondingly, container becomes big problem, and under the situation of using infusion pump, need not and can be injected into supervision such in patient's the blood vessel, so need staff and device because of a large amount of air of fault that liquid is used up pick off.
On the other hand, the infusion vessel of bag type is owing to the part except oral area is formed by softish plastic sheet, so even do not use pneumatic needle, container self also easily flattens when the outflow of medicinal liquid, so have the advantage that debris does not take place.But the infusion vessel of the type sees that from the aspect of material and form have can not axial shortcoming, is inconvenient when the transfusion operation therefore.
So, about can be axial the infusion vessel of bottle type, in order to reduce air capacity and debris, the structure that makes container become and flatten has easily been proposed.Have the structure (patent documentation 1) of 4 parallel grooves with respect to the bottom surface is set on the lateral suitable position of the wider width of trunk or be arranged on the two sides central authorities stringer of trunk, to the mountain broken line in two bights, both sides of container bottom and in the both sides of this mountain broken line the paddy broken line being set near the bottom, near the paddy broken line that makes bottom two sides and the structure (patent documentation 2) that is communicated with of the paddy broken line bottom being parallel to of leading flank etc. by the container trunk being set.
But, the shoulder of the infusion vessel of patent documentation 1 and the flattening of bottom are inadequate, thereby, be that the amount of the air that injects is more and have unsatisfied structure, in addition, about the infusion vessel of patent documentation 2, though also can approve some improvement, but the flattening of same shoulder and bottom, particularly shoulder is insufficient, thereby the air capacity of injecting is more, exists dissatisfied.
