In this utility model; Two-tube conjuncted transfusion bag accessory can be realized fill, dosing, three functions of transfusion, the welding position in the time of can reducing the production transfusion bag; 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.
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 after when transfusion, drawing back easy-to-draw diaphragm seal, makes on the other hand to keep rational distance between pad and the easy-open lid, and pad can not destroyed by high temperature when the welding easy-open lid.
That ship shirt rim 16 opening outward flanges are used for is level and smooth with the transfusion bag thin film, flexible, be tightly connected, and prevents direct poorly sealed easy to leak, the problem such as fragile of causing that be connected with soft transfusion bag thin film of rigid tube for transfusion 1 and chemical feed pipe 2.
Body seat 3 shapes sizes aspect has increased with transfusion bag with chemical feed pipe 2 than tube for transfusion 1 and has been connected area, and the minimizing connecting portion is stressed, reduces connecting portion by the probability of pulling force damage; The thickness aspect of interior clean ship formula body seat 3 is as thick and hard tube for transfusion 1 and chemical feed pipe 2, with the transitional link of hard, soft two kinds of materials of thin and soft transfusion bag thin film.The diffusing pulling force of the joint face of increasing integration prevents to damage and hard, the soft two kinds of materials of transition prevent these two kinds of effects of bending damage it is thus clear that body seat 3 has.
In order to make body seat 3 better with the welding effect of transfusion bag thin film, the edge of body seat 3 openings is ship shirt rim 16, and the thickness of ship shirt rim 16 is thinner than the thickness of ship pipe jointing part position 20.The elastic reaction of the body seat 3 of this thick middle thin edge has solved hard tube for transfusion 1 and chemical feed pipe 2 and softish transfusion bag thin film in the flimsy problem of connecting portion.
The advantage of this utility model:
This utility model is a kind of two-tube conjuncted transfusion bag accessory, can realize fill, dosing and three functions of transfusion, in the vein puncture process, is difficult for falling bits; 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 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.The matrix spacer groove 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.
This utility model 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 when transfusion, drawing back easy-to-draw diaphragm seal; 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.
The body seat is a strip, makes side-pull type filling infusion tube and chemical feed pipe that the interval of big distance can be arranged, and convenient operation when fill, dosing and transfusion is particularly suitable for machinery in transfusion bag during the fill medicine, and machinery needs the working place of broad.
