Abstract

The invention discloses a double-pipe and double-channel syringe and a needle. The double-pipe and double-channel syringe comprises a needle tubing. The needle is arranged at the front end of the needle tubing. A first partition plate is arranged in the needle tubing in the length direction and segments the needle tubing into a first cavity and a second cavity. A first piston is arranged in the first cavity. A first piston handle is arranged on the first piston. A second piston is arranged in the second cavity and connected with a second piston handle. The second piston handle is arranged outside the second cavity. The needle is segmented into a third cavity and a fourth cavity through a second partition plate in the length direction. The third cavity is communicated with the first cavity. The fourth cavity is communicated with the second cavity. Through the design that the first cavity and the second cavity are separated but the needle enters the same blood vessel, hyaluronic acid injecting and blood returning and drawing are independent, the most severe complication blood vessel embolism caused by hyaluronic acid injecting is effectively avoided, hyaluronic acid injecting can be effectively and safely conducted, and doctors and patients can be more assured of injection.

Description

A kind of Dual pipe dual passage needle and syringe head
Technical field
The invention belongs to medical treatment shaping technique field, be specifically related to a kind of Dual pipe dual passage syringe one Dual pipe dual passage needle and syringe head.
Background technology
Currently, it is very general 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 gently 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 the hemorrhage explanation syringe needle of pumpback has entered blood vessel.But owing to hyaluronic acid quality is dense 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 improvement of general hyaluronic acid syringe is contemplated to solve this problem by the design, neither affects normal injection, pumpback can detect whether intravasation again.
Summary of the invention
It is an object of the invention to provide a kind of Dual pipe dual passage syringe, solving traditional hyaluronic acid syringe of existing in prior art cannot the problem of pumpback.
The technical solution adopted in the present invention is, 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 is provided with first piston handle, being provided with the second piston in second cavity, the second piston is connected to the second piston handle, the second piston handle is arranged at the outside of the second cavity;Along its length, syringe needle is divided into the 3rd cavity and the 4th cavity by second partition, and the 3rd cavity and the first cavity are connected;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 invention has the beneficial effects as follows: the present invention 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, can effective and safe carry out hyaluronic acid injection, make doctor and more relieved the carrying out of patient inject.
Accompanying drawing explanation
Fig. 1 is the structural representation of Dual pipe dual passage syringe of the present invention.
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, the present invention is described in detail.
The present invention 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 6 is provided with first piston handle 7, being provided with the second piston 8 in second cavity 5, the second piston 8 is connected to the second piston handle 9, the second piston handle 9 is 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.
