Description

Disposable use sequential injection device
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of disposable use sequential injection device of common disposable syringe being improved to rear acquisition.
Background technology
Intravenous injection is clinical conventional treatment means, substantially all intravenous drugs are all with in normal saline washing intravasation system, need to be first with after heparin class compatibility medicine liquid washing for part and the inconsistent medicinal liquid of saline, use again salt water sealing (sealing water) pipe, to guarantee making full use of of medicinal liquid, avoid contacting with the medicine of infusion subsequently, and ensure the patency of conduit.At present, two kinds of different medicinal liquids of sequential injection still need two syringes of continuous consumption to inject respectively, not only lose time, increase nursing staff's workload, and increase the consumption of medical disposable material, and intermittent infusion has also increased the probability infecting simultaneously.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned deficiency exactly, and a kind of rational in infrastructure, easy to use, effective disposable sequential injection device of realization order infusion is provided.
The technical scheme in the invention for solving the above technical problem is:
Disposable use sequential injection device, comprise the large syringe of encapsulation injection A and the little syringe of encapsulation injection B, the front end of described large syringe is provided with the conehead with liquid outlet, little syringe inserts in the overcoat of large syringe, its front end is provided with the large piston with large syringe jacket inwall interference fit, little syringe front end liquid outlet is provided with diaphragm seal, push rod inserts in little syringe jacket, push rod front end is provided with the valve piston with little injector wall interference fit, in large syringe conehead, be provided with syringe needle and aim at the plastic connector pin of the lateral opening hole of little syringe diaphragm seal.
Described diaphragm seal is the materials such as masking foil, rubber.
The conehead of described large syringe is provided with block outward.
Described large syringe jacket end is provided with handle.
Described little syringe jacket end is provided with handle.
Described little injector push-rod end is provided with by hands.
Described large syringe piston adopts and is threaded with little syringe jacket surface.
The beneficial effects of the utility model are: the push rod that replaces large syringe with little syringe, by promoting little injection overcoat, the injection A of large syringe encapsulation is infused in human body, inject when complete at injection A, diaphragm seal on the broken little syringe of plug bottle cushion, promote little injection putter the injection B being encapsulated in little syringe is infused to human body, thereby realize the sequential injection of injection A and injection B.This utility model is simple in structure, production cost is low, two kinds of liquid of order infusion are quick and easy.
Brief description of the drawings:
Below in conjunction with accompanying drawing, this utility model is further described.
Fig. 1 is the structural representation of this utility model sequential injection device;
Fig. 2 is the anterior partial schematic diagram of the large syringe of this utility model sequential injection device;
Fig. 3 is the anterior partial schematic diagram of the little syringe of this utility model sequential injection device;
1 block in figure, 2 coneheads, 3 plastic connector pins, 4 injection A, 5 large syringes, 6 sealings, 7 large pistons, 8 injection B, 9 little syringe pistons, 10 little syringes, 11 large handles, 12 push rods, 13 miniature levers, 14 press hands, 15 side pin holes, 16 large syringe jackets, 17 little syringe jackets.
Detailed description of the invention
As shown in Figure 1-Figure 3, disposable use sequential injection device of the present utility model, comprise the large syringe 5 of encapsulation injection A4 and the little syringe 10 of encapsulation injection B8, the front end of described large syringe 5 is provided with the conehead 5 with liquid outlet, little syringe 10 inserts in the overcoat 16 of large syringe, little syringe 10 front ends are provided with the large piston 7 with large syringe jacket 16 inwall interference fit, make little syringe 10 become the push rod of large syringe 5.Little syringe 10 front end liquid outlets are provided with diaphragm seal 6, push rod 12 inserts in little syringe jacket 17, push rod 12 front ends are provided with the valve piston 9 with little syringe jacket 17 inwall interference fit, are provided with syringe needle and aim at the plastic connector pin 3 of the lateral opening hole of little syringe diaphragm seal 6 in large syringe conehead 2.For the ease of operation, be respectively equipped with handle 11 and handle 13 at large syringe jacket end and little syringe jacket end, little injector push-rod 12 ends are provided with by hands 14.
When use, opening block 1 is connected large syringe conehead 2 with infusion pipeline, the hands of pressing using the handle of little syringe 13 as large syringe, promote miniature lever 13, injection A4 in large syringe 5 is injected in blood system, along with the promotion of injection A4, little syringe forward end seal film 6 contacts with plastic connector pin 3, and plastic connector pin 3 is entered in little syringe 10, when after injection A4 infused, control miniature lever 13 and press hands 14, promoting push rod 12 moves forward, at this moment little syringe inner liquid medicine will contact the side pin hole 15 of plastic connector pin, now continue promote miniature lever 13 and press hands 14, injection B8 will enter people's Hematological System of Professional Workers along the conehead of large syringe 2, realize the sequential injection of continuous injection injection liquid A and B.
This utility model is simple in structure, easy to use, with low cost, is a kind of desirable mixed type order infusion set.
