The specific embodiment
Fig. 1 shows first embodiment of a kind of infusion set of this utility model, infusion vessel 5 is that the translucent non-toxic plastic of employing is the raw material once injection moulding, its profile is the top cover that connects a cone on the cylinder, the cone top cover of infusion vessel 5 is provided with one section infusion port that stretches out 11, and it is connected with tube for transfusion 10.Two medicinal liquid input ports 14 also are set on the cone top cover of infusion vessel 5, and medicinal liquid input port 14 has one to be screwed hole.
The below of infusion vessel 5 is provided with a pressing mechanism, and pressing mechanism is made up of collet 1, piston 4, spring 3, and the spring 3 of pressing mechanism is between collet 1 and piston 4, and piston 4 is positioned at the top of collet 1, and a sealed hollow 2 is arranged between piston 4 and the collet 1.Collet 1 is made up of the upwardly extending sidewall of a circular bottom plate and base plate edge, infusion vessel 5 cylinder outer walls bottom is provided with external screw thread, the cylindrical inner wall of collet 1 is provided with the female thread that matches with external screw thread, collet 1 and infusion vessel 5 form going to the bottom of infusion vessel 5 by being threaded and heating and seal.Can store transfusion solution 12 in the infusion vessel 5, the piston of pressing mechanism contact with transfusion solution 12 in the infusion vessel 5, and the cylindrical inner wall precision-fit of piston 4 and infusion vessel 5 can move up and down along the cylindrical inner wall of the body 5 of infusing.
The center that collet 1 forms the circular bottom plate of cavity 2 has the groove of a placement spring 3, and two tapped through holes are set on the circular bottom plate of collet 1, and two air control valves 13 are installed on it, by these two air control valves 13 cavity 2 is formed negative pressure of vacuum.Regulate air control valve 13, can regulate the pressure in the cavity 2.
Piston 4 is reached by a cylinder to be formed for the cone of one with it, and center, cylindrical below has the groove of a placement spring 3.The cone tapering of piston 4 is consistent with the cone top cover tapering of infusion vessel 5, piston 4 and infusion vessel 5 can be matched, the transfusion solution 12 that helps being mixed with medicinal liquid is unlikely to waste, and transfusion solution 12 has been totally lost in the infusion vessel 5, pressure in the cavity 2 still acts on the piston 4, the blood back phenomenon can not occur.
The top of infusion vessel 5 is provided with a drug-adding device 9.Drug-adding device 9 has a rectangular openable sealing cavity volume, two drug liquid tubes 6 that are connected with medicinal liquid input port 14 are arranged at its bottom, two ends, a drug liquid tube 6 wherein has the external screw thread that matches with screwed medicinal liquid input port 14, and another root drug liquid tube 6 matches with not threaded medicinal liquid input port 14.Medicinal fluid bag 7 is placed in the bottom of sealing cavity volume, but the top chamber wall of medicinal fluid bag 7 is provided with the perforator 8 of a precession, perforator 8 is blunt nosed pin plastic production and top medicinal fluid bag 7 chamber wall threaded engagement, or has the blunt nosed pin (not shown) that can move up and down along the hole that is provided with on the top chamber wall of medicinal fluid bag 7 of spring.Perforator 8 is gapped with medicinal fluid bag.Through the bonding of heating between tube for transfusion 10 and the infusion port 11 and between medicinal liquid input port 14 and the drug liquid tube 6.
Before treatment, need to inject transfusion solution 12 by infusion port 10, seal the drug liquid tube 6 of drug-adding device 9 with sealing film, make and fill transfusion solution 12 in the infusion vessel 5, because piston 4 can move up and down along the inwall of infusion vessel 5, and the cavity 2 of pressue device is a negative pressure of vacuum, therefore, when injecting transfusion solution 12, to promote piston 4 and move to collet 1 direction, the spring 3 under the piston 4 is compressed, and gives 4 one counteracting forces of piston, after filling transfusion solution 12 in the infusion vessel 5, keep balance at cavity 2 under the situation of negative pressure of vacuum, open air control valve 13, in the cavity 2 of air admission pressue device, increased the pressure in the cavity 2, promotion piston 4 is clamp-oned tube for transfusion 10 with the mixed transfusion solution 12 of medicinal liquid and is carried out transfusion work.
When precession perforator 8, puncture medicinal fluid bag 7, medicinal liquid flows out, mix with transfusion solution through drug liquid tube 6, when piston when tube for transfusion 10 directions are moved, transfusion solution 12 is circulated in two drug liquid tubes 6, make medicinal liquid fully mixed, need not the reuse syringe, avoided artificially extracting medicinal liquid when careless with syringe, it is not enough and influence the generation of therapeutic effect situation liquid dose to occur.
Fig. 2 shows second embodiment of a kind of infusion set of this utility model, removes its drug-adding device and is different from outside first embodiment, and other structures all are identical.Drug-adding device 9 has a foursquare openable cavity volume 17, there is the medicine of a similar ink bottle to inject chamber 15 in this cavity volume, medicine injects the accent and plastic plug 16 tight fits in chamber 15, medicine injects bottom, 15 two ends, chamber two drug liquid tubes 6 that are connected with medicinal liquid input port 14, a drug liquid tube 6 wherein has the external screw thread that matches with screwed medicinal liquid input port 14, and another root drug liquid tube 6 matches with not threaded medicinal liquid input port 14.Medicine injects between chamber 15 and the openable cavity volume 17 can vertically place four vials 18 that medicinal liquid is housed.
During rescue, open openable cavity volume 17, pull out plastic plug 16, take out the vial 18 that medicinal liquid is housed, vial 18 tops are destroyed, pour medicinal liquid into medicine and inject chamber 15, the jam-pack plastic plug 16 again.When the piston 4 of pressing mechanism when tube for transfusion 10 directions are moved, transfusion solution 12 is circulated in two drug liquid tubes 6, makes medicinal liquid fully mixed.
To be placed with a kind of infusion set of this utility model of medicinal liquid in the drug-adding device 9, unified with oxirane disinfection and standby with the outer package sealing.When to be used, tear outer package, just can give first aid to, do not need to use syringe to extract medicinal liquid.The air control valve 13 of re-adjustment infusion vessel 5 bottoms makes the cavity 2 of the negative pressure of vacuum of air admission pressing mechanism, just can not need drip stand also can finish transfusion.Reduce the transfusion step, accelerated the speed of rescue, reduced the chance of cross infection, whenever and wherever possible can normal infusion, be applicable on ambulance and the rescue in battlefield.
