Specifically, bag 1 is the container of splendid attire medicinal liquid, and it is substantially in cuboid, and certain bag 1 also can be made as other shapes, does not limit at this.The side of bag 1 is connected with chemical feed pipe 2 and grug transportation tube 3, and its opposite side is provided with hanging hole 11, is hung on a hanger by bag 1, make the medicinal liquid in bag 1 be positioned at bag 1 place of chemical feed pipe 2 and grug transportation tube 3 side under gravity to facilitate.In other embodiments, this bag 1 also can substitute with bottle, is not limited to the form of bag 1.
Chemical feed pipe 2 and grug transportation tube 3 are sealedly connected on the side of bag 1 side by side, chemical feed pipe 2 is connected with the container cavity of bag 1 respectively with grug transportation tube 3, wherein, chemical feed pipe 2 is sealedly connected with dosing interface 21, in this utility model, chemical feed pipe 2, grug transportation tube 3 and dosing interface 21 are parts well known in the prior art, its concrete structure no longer describes at this, such as, chemical feed pipe 2 and grug transportation tube 3 can be pipe body shape, the two can respectively with bag 1 seal welding, or after the two is combined into one by a connection piece, to be tightly connected by this connector and bag 1; Dosing interface 21 seal welding, in chemical feed pipe 2, can contain interior plug in this dosing interface 21, at needs in bag 1 during dosing, by acupuncture dosing interface 21, makes that needle-penetration is interior fills in, can realize the object of dosing in bag 1.
Transfusion device 5 is the medical apparatus to human transfusion, and this transfusion device 5 and infusion tube 51 thereof are parts well known in the prior art, and its concrete structure does not repeat them here.In this utility model, the infusion tube 51 of transfusion device 5 is connected with grug transportation tube 3 by a connection tube 4, and be sealedly connected with the plug 6 that fractures between grug transportation tube 3 and connection tube 4, this plug 6 that fractures, for sealed joint pipe 4 and grug transportation tube 3, prevents the medicinal liquid in bag 1 from spilling.
As shown in Figure 2, the plug 6 that fractures has body 61 and broken portion 62, body 61 is substantially in cylinder barrel shaped, it has hollow cavity 612, the upper end of body 61 is formed with link 611, this link 611 is welded to connect with grug transportation tube 3, and the hollow cavity 612 of body 61 is connected by the container cavity of grug transportation tube 3 with bag 1.The bottom of body 61 is inserted in connection tube 4, and is welded to connect on the inwall of connection tube 4.Certainly, in other implementations, interference fit or bonding connected mode also can be adopted to interconnect between link 611 with grug transportation tube 3 and between body 61 with connection tube 4, this is not restricted.
In this utility model, the outer wall of body 61 is convexly equipped with stopper section, this stopper section is located between grug transportation tube 3 and connection tube 4, and it is for isolating grug transportation tube 3 and connection tube 4, and plays and make body 61 form the effect of intact sealing with grug transportation tube 3 and connection tube 4 respectively.In one embodiment, as shown in Figure 2, stopper section can be the baffle ring 613 of a circular in configuration; In another embodiment, as shown in Figure 3, stopper section be two stop blocks, 614, two stop blocks 614 diametrically projection on the outer wall of body 61, stopper section is set to two stop blocks 614, can saves material.
Broken portion 62 is positioned at connection tube 4 and is connected to the lower end of body 61, and it can be cylindrical, also can be the inverted round stage bodily form, arranges the structure that can simplify broken portion 62 injection forming mold like this.Snap slot 621 is formed between broken portion 62 and body 61, in the present embodiment, the cross section of this snap slot 621 is V-shaped, be V-arrangement by the Cross section Design of snap slot 621, can guarantee that, when broken portion 62 is arranged in connection tube 4, staff can be realized the object of broken portion 62 under body 61 is pulled by suitable folding power of pulling.Certainly, in other implementations, the cross section of this snap slot 621 also can be taper, or this snap slot 621 is designed to circumferential intermittent formula syndeton (such as, being circumferentially provided with multiple fault troughs), and this is not restricted.
The hollow cavity 612 of body 61 extends to snap slot 621 place, and before discharging the retained water is pulled from body 61 by broken portion 62, broken portion 62 can reach the effect of the hollow cavity 612 in complete seal body portion 61.
Expand termination 63 and be shaped in one end away from body 61, broken portion 62, in this utility model, the external diameter of this expansion termination 63 is greater than the external diameter in broken portion 62, the benefit of such setting is, when broken portion 62 and expansion termination 63 are positioned at connection tube 4, are convenient to staff and grip expansion termination 63 through connection tube 4 and pull the broken portion 62 of folding.In the present embodiment, the external diameter of this expansion termination 63 is slightly smaller than the internal diameter of connection tube 4 and is greater than the internal diameter of infusion tube 51, thus after broken portion 62 is fractureed, by expanding the effect of termination 63, broken portion 62 can be retained in connection tube 4, and broken portion 62 can not enter in infusion tube 51.
This expansion termination 63 is along the circumferential direction provided with multiple flow path groove 631, those flow path groove 631 are for when broken portion 62 departs from body 61 and is trapped in connection tube 4, and the medicinal liquid flowed out from bag 1 flows in the infusion tube 51 of the transfusion device 5 be connected to below connection tube 4 by those flow path groove 631.In the present embodiment, this expansion termination 63 is inversed-cone shape, and its taper angle theta is obtuse angle, particularly the obtuse angle of non-pointed shape, and this setting can prevent in transportation, and transfusion device 5 and infusion tube 51 thereof and connection tube 4 are punctured by the broken portion 62 of tip.In the present embodiment, this cone angle is 100 ° ~ 150 °.
Transfusion flexible bag system of the present utility model, infusion safety can be improved, be connected owing to adopting fracture plug 6 and connection tube 4 between bag 1 with transfusion device 5, eliminate the use of infusion connector, production cost can be reduced, and the transfusion flexible bag that this transfusion flexible bag system is made without the need to using the complicated film with inner rosin joint structure, it uses the soft bag of common transfusion; Meanwhile, owing to avoiding with needle pierces loading interface, avoid elastomer exfoliation, therefore avoid affecting medicinal liquid physicochemical property and avoiding exfoliation to enter human body.In addition, when transfusion operation, the broken portion 62 of the plug 6 that fractures is folded down and can realizes transfusion, simplify nurse operation.Further, due to the plug 6 that fractures are Merlon hardened member, and be assemblied in connection tube 4, it is more easily controlled by the power fractureed, and needs artificial bending to be fractureed, and transfusion is flowed down, therefore more can ensure the safety of system in transportation.
The foregoing is only several embodiment of the present utility model, those skilled in the art can carry out various change or modification to this utility model embodiment according to content disclosed in application documents and not depart from spirit and scope of the present utility model.
