Abstract
The utility model discloses an infusion bag accessory with double tubes, a saddle-type tube seat and an easy-tearing sealing film, which comprises a soft platy plastic tube seat, an infusion tube, a feeding tube, a triangular film-covered plate, a platy film connecting portion and a platy tube connecting portion. A sealing partition film hollowly arranged in the infusion tube can guarantee the surface of a sterilized cushion plate to be in a constant aseptic state. Rubber cushion scraps can be avoided in infusion, the infusion tube prevents slipping of an infusion needle and liquid leakage by the aid of friction force of the infusion needle with the inner wall of the infusion tube and conical self-locking function of the infusion tube, the infusion bag accessory avoids sterilization for the outer surface of the cushion plate before liquid medicine is injected into or taken out of a container, a portion with a thick center manufactured on the soft platy plastic tube seat is connected with the infusion tube and the feeding tube which are made of hard materials so as to realize optimal transitional connection of a thin portion of the plastic soft platy tube seat with the soft film of the infusion bag, and accordingly the infusion bag accessory prevents the liquid medicine inside a bag body spilling out and prevents the liquid medicine inside the bag from being polluted by external microorganisms.
Description
Technical field
This utility model belongs to medical infusion packing technique field, particularly has the two-tube transfusion bag accessory of dosing and two kinds of functions of transfusion
Background technology
Existing transfusion bag accessory generally has two kinds, a kind of is the single tube structure, form by interface and seal cover, dosing and transfusion are all undertaken by this single tube passage, its shortcoming is that the employed seal cover of this structure generally is made up of three parts: inner cap, enclosing cover and place inner cap and enclosing cover between pad (as the polyisoprene pad).When transfusion with thick resin needle penetration pad and inner cap,, in piercing process, pad and inner cap all easily fall bits, more can repeatedly puncture when dosing, have further increased the probability of falling to consider to be worth doing, often cause medicinal liquid contaminated; And penetration Resistance is big, and is not easy to operate; In addition, the production cost of this seal cover is also higher.Another kind is two single tube structures arranged side by side, and one is a chemical feed pipe, and it two is a tube for transfusion, this double pipe structure welds with the transfusion bag diaphragm seal respectively for two mouth pipes independently, two welding positions are arranged when the production transfusion bag, and the production technology cost is higher, and has increased the probability of medicinal liquid seepage.
The utility model content
Structure of the present utility model is:
Have and easily tear the two-tube of diaphragm seal and saddle type body seat transfusion bag accessory, comprise that plastic film body seat 1, tube for transfusion 2, chemical feed pipe 3, triangle film coated plate 6, sheet symphysis connect position 10, it is characterized in that: both connecting portions of tube for transfusion 2 and chemical feed pipe 3 are sheet pipe jointing part position 11, the edge of plastic film body seat 1 connects position 10 for the sheet symphysis, and the thickness of sheet pipe jointing part position 11 connects the thickness at position 10 greater than the sheet symphysis; The other end of tube for transfusion 2 and chemical feed pipe 3 stretches out and forms triangle film coated plate 6.
Tube for transfusion 2 one ends link to each other with plastic film body seat 1, and hollow and plastic film body seat 1 point of attachment be provided with tube for transfusion seal dissepiment 4, and the other end stretches out and forms triangle film coated plate 6, triangle film coated plate 6 and easily tore film 9 welding.
The internal diameter of tube for transfusion 2 is slightly less than the internal diameter of transfusion needle, and the polypropylene plastics material has certain elasticity, and tube for transfusion 2 can be placed the transfusion needle landing by frictional force with transfusion needle during puncture;
Seal dissepiment in tube for transfusion 2 and chemical feed pipe 3, seal dissepiment is suitably thick, when the people pushes liquid in the infusion bottle, and the fluid pressure packing film of decoding that can not rise, and transfusion needle can easier be punctured decode the packing film, make transfusion needle can touch solution in the infusion bottle.
The purpose of this utility model provide a kind of have easily tear the two-tube of diaphragm seal and saddle type body seat transfusion bag accessory, can realize dosing, two functions of transfusion, simultaneously in the vein puncture process, be difficult for falling bits, be easy to puncture, its tube for transfusion 2, chemical feed pipe 3 and bag material connecting portion are not fragile, and can guarantee that sterilization dosing hole, back and infusion hole are in aseptic condition all the time, the unlatching of easily tearing diaphragm seal during transfusion can be once from the dosing hole to infusion hole or secondary finish, need not sterilize, thereby prevent that the powder charge hydrorrhea goes out and an external microbe pollution bag inner liquid medicine in the bag.The utlity model has antiforge function, can discern and whether in drug container, added medicine or got medicine.
Tube for transfusion 2 and chemical feed pipe 3 separate cross-contamination when avoiding using medicinal liquid; The hollow of tube for transfusion 2 is provided with tube for transfusion seal dissepiment 4, when the people pushes liquid in the infusion bottle, the fluid pressure tube for transfusion seal dissepiment 4 that can not rise brokenly, and make the transfusion needle tube for transfusion seal dissepiment 4 that can easier puncture brokenly makes transfusion needle can touch solution in the infusion bottle.During transfusion, can not have the rubber cushion bits again, the frictional force and the tapering self-locking action of tube for transfusion 2 dependence and transfusion needle and tube for transfusion 2 inwalls prevent transfusion needle landing and leakage.Chemical feed pipe 3 is provided with chemical feed pipe seal dissepiment 5 with interior centre position, is provided with pad 7 more than the seal dissepiment, and triangle film coated plate 6 is provided with easily tore film 9 can guarantee that the sterilization back need not carry out disinfection to the outer surface of pad before injecting or taking out medicinal liquid in container; Plastic film body seat 1 is made thick position, center and is connected with chemical feed pipe 3 with the tube for transfusion 2 of hard material, and thin position is connected with the mantle optimum transfer of transfusion bag; Thereby prevented that the powder charge hydrorrhea goes out and an external microbe pollution bag inner liquid medicine in the bag; Production cost is low.
