Abstract
The invention relates to an infusion bag part with a fusiform seat, a top pull infusion tube and a gasket ring dosing tube, and belongs to a pipeline for liquid to pass in and out of an infusion bag and a pipeline sealing device. The infusion bag part comprises the top pull infusion tube, the dosing tube and the fusiform tube body seat, and is characterized in that: the top pull infusion tube and the dosing tube are fixed on the same surface of the fusiform tube body seat and basically parallel to each other; a top pull infusion needle conduit is hollow and provided with a sealing diaphragm, and the top end of the top pull needle conduit is provided with a top pull sealing cover for sealing the top pull needle conduit; and a gasket is arranged in the dosing tube, a gasket fixing ring is arranged on the gasket, and the top of the dosing tube is sealed by an easy open end. The infusion bag part has the advantages that: the infusion bag part is a double tube integrated infusion bag part, can realize the functions of dosing and infusing, reduce welding positions during infusion production, and reduce the probability of liquor leakage; and meanwhile, scraps are difficult to fall off in the process of infusion and puncture, the infusion bag part is convenient to puncture, and the production cost of the infusion bag part is relatively low.
Description
Technical field
The invention belongs to medical infusion packing technique field, particularly have the two-tube transfusion bag accessory of dosing and two kinds of functions of transfusion.
Background technology
The transfusion bag accessory requires to have the transfusion function, preferably also the dosing function should be arranged.
Existing transfusion bag accessory generally has two kinds; A kind of is the single tube structure; Form by interface and seal cover; Dosing with the transfusion all carry out through 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 (like the polyisoprene pad).With thick resin needle penetration pad and inner cap, in piercing process, pad and inner cap all are prone to bits, when dosing, more can repeatedly puncture when transfusion, have further increased the probability of falling bits, 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 of which 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 invention is to provide a kind of two-tube conjuncted transfusion bag accessory; Can realize dosing, two functions of transfusion; Welding position in the time of can reducing transfusion production, the probability of reduction medicinal liquid seepage is difficult for falling bits simultaneously in the vein puncture process; Be easy to puncture, and the production cost of this transfusion bag accessory is also lower.
A further object of the invention is; The spacers ring is set between pad and easy-open lid; On the one hand pad is played fixation; Pad can not become flexible after transfusion the time is drawn back easy-to-draw diaphragm seal, make on the other hand pad with and easy-open lid between keep rational distance, pad can not destroyed by high temperature when welding easy-open lid.
Structure of the present invention is:
The transfusion bag accessory of fusiformis seat band top-pull type transfusion pipe and gasket ring chemical feed pipe; Comprise a top-pull type transfusion pipe 1, chemical feed pipe 2 and fusiformis body seat 3; It is characterized in that: top-pull type transfusion pipe 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 top-pull type transfusion pipe 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.
Top-pull type transfusion pipe 1 is formed by connecting body 5, push-pull-type infusion needle guide tube 4 and push-pull-type seal cover 7 three parts, connects body 5 and is connected to become the logical structure in interior Kongxiang with fusiformis body seat 3; Push-pull-type infusion needle guide tube 4 one port edges stretch out into welding ring 6, and the edge, another port stretches out and becomes to hold ring 61, and with is connected body 5 connections; The hollow cross-section of push-pull-type infusion needle guide tube 4 is provided with seal dissepiment 19; Be sealed with push-pull-type seal cover 7 on the welding ring 6; Push-pull-type seal cover 7 comprises push-pull-type matrix lid 30 and push-pull-type draw ring 31, is push-pull-type diaphragm seal 32 in the middle of the push-pull-type matrix lid 30, and push-pull-type diaphragm seal 32 peripheries are provided with easy-to-draw impression, and push-pull-type draw ring 31 is connected above the push-pull-type diaphragm seal 32;
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 of matrix spacer groove circle 12, 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 top-pull type transfusion pipe 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 invention:
The thickness of pad 11 is 4.0-6.0mm;
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;
Advantage of the present invention:
The present invention is a kind of two-tube conjuncted transfusion bag accessory, can realize dosing, two functions of transfusion, the 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 be 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, before in bag, injecting or taking out medicinal liquid, must not carry out disinfection to the pad outer surface.Matrix spacer groove circle makes falling bits and can not getting 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.
The present invention is provided with the spacers ring between pad and easy-open lid; On the one hand pad is played fixation; Pad can not become flexible after transfusion the time is drawn back easy-to-draw diaphragm seal, make on the other hand pad with and easy-open lid between keep rational distance, pad can not destroyed by high temperature when welding easy-open lid.
