The transfusion bag accessory of fusiformis seat band push-pull-type filling infusion tube and gasket ring chemical feed pipe
Technical field
This utility model belongs to medical infusion packing technique field, particularly has the two-tube transfusion bag accessory of fill, dosing and three kinds of functions of transfusion.
Background technology
The transfusion bag accessory requires to have fill function, dosing function and transfusion function.
Existing transfusion bag accessory generally has two kinds, a kind of is the single tube structure, form by interface and seal cover, fill, 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).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 bits, often cause medicinal liquid contaminated when transfusion; 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.
Summary of the invention
The purpose of this utility model provides a kind of two-tube conjuncted transfusion bag accessory, can realize fill, dosing and three functions of transfusion, welding position in the time of can reducing transfusion production, reduce the probability of medicinal liquid seepage, simultaneously in the vein puncture process, be difficult for falling bits, be easy to puncture, and the production cost of this transfusion bag accessory is also lower.
This utility model also has a purpose to be, the spacers ring is set between pad and easy-open lid, on the one hand pad is played fixation, pad can not become flexible draw back easy-to-draw diaphragm seal when transfusion after, make on the other hand to keep rational distance between pad and the easy-open lid, pad can not destroyed by high temperature when the welding easy-open lid.
Structure of the present utility model is:
The transfusion bag accessory of fusiformis seat band push-pull-type filling infusion tube and gasket ring chemical feed pipe, comprise a push-pull-type filling infusion tube 1, chemical feed pipe 2 and fusiformis body seat 3, it is characterized in that: push-pull-type filling infusion tube 1 and chemical feed pipe 2 all are fixed on the same one side of fusiformis body seat 3, and both are substantially parallel.Fusiformis body seat 3 is used for and the smooth connection of transfusion bag thin film, prevents that push-pull-type filling infusion tube 1 and chemical feed pipe 2 directly is connected poorly sealed easy to leak, the problem such as fragile of causing with the transfusion bag thin film.

The logical integrative-structure in Kongxiang in chemical feed pipe 2 is connected to become with fusiformis body seat 3; Chemical feed pipe 2 is made up of dosing body 21, matrix spacer groove circle 12, pad 11, spacers ring 17,10 5 parts of easy-open lid; The open end of dosing body 21 is provided with matrix spacer groove circle 12, is provided with pad barrier film 22 near sky in the chemical feed pipe 2 of matrix spacer groove circle 12; Pad barrier film 22 is provided with pad 11, is provided with spacers ring 17 above the pad 11; Easy-open lid 10 comprises easy-to-draw matrix lid 13 and pull-tab 14, is easy-to-draw diaphragm seal 15 in the middle of the easy-to-draw matrix lid 13, and easy-to-draw diaphragm seal 15 peripheries are provided with easy-to-draw impression, and pull-tab 14 is connected above the easy-to-draw diaphragm seal 15; The lid welding ring 23 of the easy-to-draw matrix lid 13 of easy-open lid 10 is tightly connected with the pad welding ring 24 at matrix spacer groove circle 12 tops, and lid welding ring 23 is crimped on the spacers ring 17;
There are two perforates the middle part of fusiformis body seat 3, and a hole communicates with push-pull-type filling infusion tube 1, and another hole communicates with chemical feed pipe 2; Fusiformis body seat 3 bottom pars intermedia bit wides are rectangle, and two ends are shunk triangular in shape, and integral body is the fusiformis body structure.Two sides 16 of fusiformis body seat 3 are for being used for the solder side with the smooth connection of transfusion bag thin film.
Following structure is a preferred form of the present utility model:
The thickness of pad 11 is 4.0-6.0mm, and pad barrier film 22 thickness are 0.3-1.0mm;
Push-pull-type infusion needle guide tube 4 internal diameters are less than or equal to and connect body 5 internal diameters;
19 one-tenth shallow " V " shapes of seal dissepiment, " V " shape opening direction is the direction of push-pull-type seal cover 7;
Fusiformis body seat 3 both side surface that are used for being connected with the transfusion bag thin film are respectively equipped with a plurality of depression lattice 20;
Flakiness 18 extends respectively at fusiformis body seat 3 two ends.
Advantage of the present utility model:
This utility model is a kind of two-tube conjuncted transfusion bag accessory, can realize fill, dosing and three functions of transfusion, is difficult for falling bits in the vein puncture process, be easy to puncture, reduced the welding position simultaneously, reduced the probability of medicinal liquid seepage, and the production cost of this transfusion bag accessory has been also lower.
Being tightly connected of easy-open lid and matrix spacer groove circle can guarantee that chemical feed pipe water when sterilization can not infiltrate, and inner any position is in aseptic condition all the time, must not carry out disinfection to the pad outer surface before injecting in bag or taking out medicinal liquid.Matrix spacer groove circle makes falling bits and can not entering in the transfusion bag of pad, has got rid of to fall bits and has polluted.The easy-to-draw opening structure of easy-open lid can be simplified transfusion operation.
This utility model is provided with the spacers ring between pad and easy-open lid, on the one hand pad has been played fixation, pad can not become flexible draw back easy-to-draw diaphragm seal when transfusion after, make on the other hand pad and and easy-open lid between keep rational distance, pad can not destroyed by high temperature when the welding easy-open lid.
