Abstract
The utility model is a double-tube with a diaphragm seal and a transfusion bag accessory with a hollow ship-shaped tube seat. The double-tube and the transfusion bag accessory comprise a soft plastic tube seat, a transfusion tube, a medicine feeding tube, a triangular film-covered board, the film pieces connecting part and the tube pieces connecting part. The diaphragm seal arranged in the transfusion tube can keep the outer surface of the spacer in the germ-free state after the sterilization all the time; the rubber spacer bits cannot happen again when transfusion; the friction between the transfusion needle and the inner side of the transfusion tube and the self-locking taper function can prevent the transfusion needle from sliding off and leaking potions. The outer surface of the spacer are not needed the sterilization before the input and output of the potions; the part of the soft plastic tube seat with a thick center is connected with the hard material transfusion tube 2 and the medicine feeding tube; the thin part of the soft plastic tube seat is transitionally well connected with the soft film of the transfusion bag, therefore the potions in the bag can be stopped overflowing and being polluted by the outside microbe.
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
The tube for transfusion of medical infusion bags, chemical feed pipe are main accessories, because it is harder that the material of tube for transfusion, chemical feed pipe requires, and the requirement of the material of transfusion bag is softer, cause harder tube for transfusion, chemical feed pipe and a very soft bag connecting portion to produce breakage, thereby the powder charge hydrorrhea is gone out and external microbe pollutes a bag inner liquid medicine because of bending; 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:
Two-tube and the interior clean ship formula body seat transfusion bag accessory that easily tears diaphragm seal is arranged, comprise that ship shape body seat 1, tube for transfusion 2, chemical feed pipe 3, triangle film coated plate 6, ship symphysis connect position 10, it is characterized in that: both connecting portions of tube for transfusion 2 and chemical feed pipe 3 are ship pipe jointing part position 11, the edge of ship shape body seat 1 connects position 10 for the ship symphysis, and the thickness of ship pipe jointing part position 11 connects the thickness at position 10 greater than the ship 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 ship shape body seat 1, and hollow and ship shape 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.

Fig. 1 is that outward appearance of the present utility model is looked up structural representation;
Fig. 2 is an outward appearance plan structure sketch map of the present utility model;
Fig. 3 is a cross-sectional view of the present utility model;
1 is plastic film body seat, the 2nd among the figure, tube for transfusion, the 3rd, and chemical feed pipe, the 4th, tube for transfusion seal dissepiment, the 5th, chemical feed pipe seal dissepiment, the 6th, triangle film coated plate, the 7th, pad, the 8th, trim ring, the 9th, easily tore film, 10 symphysis connect position, 11 pipe jointing part positions
The purpose of this utility model provides a kind of two-tube and interior clean ship formula body seat transfusion bag accessory that easily tears diaphragm seal that has, 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; Ship shape 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.
