Abstract
The utility model discloses a double -barrelled binary channels syringe and syringe needle. The syringe: including the needle tubing, the front end of needle tubing is provided with the syringe needle, along length direction, is provided with first baffle in the needle tubing, and first cavity and second cavity are cut apart into through first baffle to the needle tubing, are provided with first piston in the first cavity, are provided with first piston handle on the first piston, are provided with the second piston in the second cavity, are connected with second piston handle on the second piston, and second piston handle sets up in the outside of second cavity, along length direction, third cavity and fourth cavity are cut apart into through the second baffle to the syringe needle, and the third cavity is linked together with first cavity, the fourth cavity is linked together with the second cavity. The utility model discloses a same hematal design is gone into to the separately nevertheless syringe needle of first cavity and second cavity, and to realize injecting the glass uric acid relatively independent with pumpback blood, has effectively avoided the most serious complication blood vessel embolism of glass uric acid injection, effective safe glass uric acid injection of carrying on, and make the doctor and the patient more sets one's mind at rest injects.
Description
Technical field
This utility model belongs to medical treatment shaping technique field, is specifically related to a kind of Dual pipe dual passage needle and syringe head.
Background technology
Currently, it is very universal that implant (particularly hyaluronic acid) injects micro-shaping, but adverse side effect happens occasionally, and the most serious surely belongs to blood vessel embolism, and blood vessel embolism the most then causes cutaneous necrosis, heavy then can cause blind, even death.If syringe needle intravasation, and inject hyaluronic acid, hyaluronic acid will be made to enter blood, cause blood vessel embolism.Currently, it is judged that whether syringe needle enters blood vessel the easiest most effective method to syringe needle is pumpback, if pumpback hemorrhage explanation syringe needle has entered blood vessel.But owing to hyaluronic acid quality is thick, adding hyaluronic acid injection needle relatively carefully, pressure problem cannot pumpback.Current implant syringe is exactly common single tube single cavity injection device, and the design is contemplated to solve this problem to the improvement of general hyaluronic acid syringe, neither affects normal injection, can detect whether intravasation with pumpback again.
Utility model content
The purpose of this utility model is to provide a kind of Dual pipe dual passage syringe, and solving tradition hyaluronic acid syringe present in prior art cannot the problem of pumpback.
This utility model be employed technical scheme comprise that, a kind of Dual pipe dual passage syringe, including needle tubing, the front end of needle tubing is provided with syringe needle, along its length, being provided with the first dividing plate in needle tubing, needle tubing is divided into the first cavity and the second cavity by the first dividing plate, is provided with first piston in the first cavity, first piston handle it is provided with on first piston, being provided with the second piston in second cavity, the second piston connects has the second piston handle, the second piston handle to be arranged at the outside of the second cavity；Along its length, syringe needle is divided into the 3rd cavity and the 4th cavity, the 3rd cavity and the first cavity to be connected by second partition；4th cavity and the second cavity are connected.
Further, the side of the second cavity is provided with elongate holes, and the second piston handle is stretched out outside the second cavity by elongate holes.
Further, the external diameter of syringe needle is 0.4mm；The internal diameter of syringe needle is 0.25mm.
The beneficial effects of the utility model are: this utility model by hyaluronic acid chamber (the first cavity) and air chamber (the second cavity) separately but syringe needle enters the design of same blood vessel that to realize injecting hyaluronic acid relatively independent with pumpback blood, effectively prevent the complication blood vessel embolism that hyaluronic acid injection is the most serious, hyaluronic acid injection can be carried out with effective and safe, make doctor and more relieved the carrying out of patient inject.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model Dual pipe dual passage syringe.
In figure, 1. needle tubing, 2. syringe needle, 3. the first dividing plate, 4. the first cavity, 5. the second cavity, 6. first piston, 7. first piston handle, 8. the second piston, 9. the second piston handle, 10. second partition, 11. the 3rd cavitys, 12. the 4th cavitys, 13. elongate holes.
Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is described in detail.
This utility model provides a kind of Dual pipe dual passage syringe, as shown in Figure 1, including needle tubing 1, the front end of needle tubing is provided with syringe needle 2, along its length, the first dividing plate 3 it is provided with in needle tubing 1, needle tubing 1 is divided into the first cavity 4 and the second cavity 5 by the first dividing plate 3, it is provided with first piston 6 in first cavity 4, first piston handle 7 it is provided with on first piston 6, being provided with the second piston 8 in second cavity 5, the second piston 8 connects has the second piston handle 9, the second piston handle 9 to be arranged at the outside of the second cavity 5；Along its length, syringe needle 2 is divided into the 3rd cavity 11 and the 4th cavity 12 by second partition 10, and the 3rd cavity 11 is connected with the first cavity 4；4th cavity 12 is connected with the second cavity 5.The side of the second cavity 5 is provided with elongate holes 13, and the second piston handle 9 is stretched out outside the second cavity 5 by elongate holes 13.The external diameter of syringe needle 2 is 0.4mm；The internal diameter of syringe needle 2 is 0.25mm.
In use, it is contained with hyaluronic acid in the first cavity 4；Syringe needle 2 is entered the tissue location needing injection；Pulling back the second piston handle 9, the second piston handle 9 moves along elongate holes 13；See if there is blood and enter the second cavity 5 by the 4th cavity 12；If entering the second cavity 5 without blood, promoting piston handle 1, making hyaluronic acid pass through the 3rd cavity 11 and be injected in tissue；Repeat above operation, complete the injection of hyaluronic acid.
