Abstract
The utility model provides a single vertical pipe sealing cover for a shuttle-shaped pipe body seat, which comprises a shuttle-shaped pipe body seat and a transfusion pipe, wherein one end of the transfusion pipe is fixed on the shuttle-shaped pipe body seat; the other end of the transfusion pipe extends outwards to form a welding ring; and an easily-torn film is connected on the welding ring in a welding manner. The sealing cover has the following advantages: as the shuttle-shaped pipe body seat is connected with the transfusion pipe into a whole, the working procedure of welding the transfusion pipe with a connecting pipe body can be reduced during the production of transfusion bags, and the pollution rate of liquid medicine is lowered after the transfusion bags are formed; the transfusion pipe prevents the falling of a transfusion needle and liquid leakage depending on the friction between the transfusion needle and the inner wall of the transfusion pipe and the taper self-locking function; during transfusion, a puncture sealing diaphragm cannot easily shed off scraps but is easy to puncture, while a present rubber pad can easily shed off scraps during puncture; moreover, the sealing cover has lower production cost.
Description
Technical field
This utility model fusiformis body seat list standpipe seal cover belongs to the supporting medicated bag material accessory of polypropylene transfusion bag.
Background technology
The accessory of existing plastic infusion bag comprises body seat (interface) and two parts of seal cover, earlier body seat and thin film heat seal is welded when producing plastic infusion bag, seal cover and the heat seal of body seat is welded after pouring into medicinal liquid again.This manufacture method has increased welding sequence one, must increase welding post on bag making, filling and sealing machine, thereby increase the device fabrication cost, and easily pollute when producing transfusion.Existing seal cover is made up of three parts again: inner cap, enclosing cover and place inner cap and enclosing cover between rubber sheet gasket (as the polyisoprene pad).When transfusion,, contact the back with medicinal liquid and realize transfusion with resin needle penetration rubber sheet gasket and inner cap.Because rubber sheet gasket and inner cap are thicker, in piercing process, rubber sheet gasket and inner cap all easily fall bits, often cause medicinal liquid contaminated; Penetration Resistance is big, and is not easy to operate; In addition, the production cost of this combined sealed cap is also higher.
The utility model content
Structure of the present utility model is:
This utility model fusiformis body seat list standpipe seal cover comprises fusiformis body seat 1, tube for transfusion 2.It is characterized in that: tube for transfusion 2 one ends be fixed on fusiformis body seat 1 above, the other end stretches out and forms welding ring 6, easily tore film 7 is connected on the welding ring 6 by welding manner.
Tube for transfusion 2 links to each other with fusiformis body seat 1, comprises transfusion body seat 3 and infusion needle guide tube 4, is provided with seal dissepiment 5 at transfusion body seat 3 to infusion needle guide tube 4 transition positions, and infusion needle guide tube 4 upper ends extend to form welding ring 6, welding ring 6 and easily tore film 7 welding.
The internal diameter of infusion needle guide tube 4 is slightly less than the internal diameter of transfusion needle, and the polypropylene material has certain elasticity, and infusion needle guide tube 4 can be placed the transfusion needle landing by frictional force with transfusion needle during puncture; In addition, infusion needle guide tube 4 top internal diameters are slightly larger than the bottom internal diameter, make infusion hole form about 1 ° tapering, and when the transfusion needle puncture entered infusion needle guide tube 4, the effect that can pass through the tapering self-locking had been avoided leakage with tightly clamping of transfusion needle like this.
Seal dissepiment in tube for transfusion 4, seal dissepiment 5 is suitably thick, promptly but people when pushing liquid in the infusion bottle, and the fluid pressure packing film 5 of decoding that can not rise, and transfusion needle can easier be punctured decode packing film 5, make transfusion needle can touch solution in the infusion bottle.
The fusiformis body seat 1 two ends flakiness 10 that extends respectively makes the sealing of fusiformis body seat 1 two ends and transfusion bag better.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a perspective view of the present utility model;
Fig. 3 is a cross-sectional view of the present utility model;
1 is fusiformis body seat, the 2nd among the figure, tube for transfusion, the 3rd, transfusion body seat, the 4th, infusion needle guide tube, the 5th, seal dissepiment, the 6th, welding ring, the 7th, easily tore film, the 8th, two sides, the 9th of fusiformis body seat, depression lattice, the 10th, thin slice.
The purpose of this utility model provides a kind of single vertical pipe sealing cover for shuttle-shaped pipe body seat, does not contain the rubber sheet gasket part in its structural design, has therefore reduced the possibility of falling bits, reduces the contaminated probability of soup; Infusion bag fitting needs only one welding sequence, and contaminated probability is low after the composition infusion bag, with infusion bag film energy good seal, and can guarantee to be in all the time germ-free condition after the infusion hole sterilization. Spindle pipe body base 1 and woven hose 2 are combined as a whole, when using the utility model production infusion bag, can reduce by one woven hose and be connected the body welding sequence, reduced the contaminated probability of soup after the composition infusion bag; Frictional force and the tapering self-locking action of woven hose 2 dependence and transfusion needle and woven hose 2 inwalls prevent transfusion needle landing and leakage. Puncture seal barrier film 5 is difficult for falling bits when transfusion, is easy to puncture, and bits are easily fallen in existing rubber blanket puncture; The utility model production cost is lower.
The specific embodiment
