Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a plastic and leak-proof double-connected medicine-mixing syringe nozzle. Background Art

[0002] When using a double-mixing syringe to mix drugs, the drugs need to be sprayed on the affected area in actual applications. If the double-mixing syringe needs to be temporarily stored after the nozzle is installed, the nozzle needs to be kept upward. If the nozzle of the mixing syringe is accidentally knocked over or other reasons cause it to be placed downward or flat, the liquid may flow to the nozzle of the mixer, causing the drugs to mix prematurely, affecting the use effect. When spraying, the spraying position may not be suitable for nozzle operation, and the operator's hands or other body parts may come into contact with other parts of the patient while spraying, posing a risk of infection. Utility Model Content

[0003] The utility model provides a plastic and leak-proof double-connected medicine-mixing syringe nozzle to overcome the deficiencies of the prior art.

[0005] The rear end of the medicine liquid pipeline is communicated with the syringe outlet through an inverted Y-shaped pipeline.

[0006] The rubber nozzle is fixed in the mounting hole by glue.

[0007] The material of the catheter is one of TPU, PE, PVC and TPE.

[0008] The rubber nozzle is made of halogenated butyl rubber.

[0009] The cross section of the conduit is elliptical.

[0010] Compared with the prior art, the utility model has a plastic catheter that can be used to spray wounds with complex conditions and angles, and when preparing to spray, the leak-proof spray head can also protect the liquid medicine from being mixed in advance and affecting the treatment effect when the double mixer is inverted.

[0014] See also Figure 1-Figure 2 , wherein 1 is a catheter, 1-1 is a metal wire, 1-2 is a drug liquid pipeline, 1-3 is a syringe outlet, 2 is a rubber nozzle, 2-1 is a drug liquid channel, 2-2 is a slit, and 2-3 is a nozzle. DETAILED DESCRIPTION

[0015] The utility model is further described below with reference to the accompanying drawings.

[0016] like Figure 1-Figure 2 As shown, it includes a catheter 1, characterized in that: a metal wire 1-1 is provided in the middle of the catheter 1, liquid medicine pipes 1-2 are provided on both sides of the catheter 1, a mounting hole is provided at the front end of the catheter 1, a rubber nozzle 2 is embedded in the mounting hole, liquid medicine channels 2-1 are provided on both sides of the rubber nozzle 2, the end of the liquid medicine channel (2-1) is a slit 2-2, the slit 2-2 is connected to the nozzle 2-3, and the front end of the liquid medicine channel 2-1 is connected to the liquid medicine pipes 1-2 on both sides of the rubber nozzle 2. After the catheter 1 is bent, the metal wire 1-1 is used to shape it to ensure that the catheter 1 does not rebound, the liquid medicine enters the slit 2-2 through the liquid medicine pipe 2-1, the slit 2-2 is in the shape of a knife edge, and pressure is required to discharge the liquid, which can prevent leakage, and the liquid medicine is mixed and sprayed out from the nozzle after passing through the slit 2-2.

[0017] The rear end of the liquid medicine pipeline 1-2 is communicated with the syringe outlet 1-3 through an inverted Y-shaped pipeline. The inverted Y-shaped pipeline is convenient for arranging the syringe outlet 1-3. There are two syringe outlets 1-3, which are connected to a double syringe for injecting two liquid medicines.

[0018] The rubber nozzle 2 is fixed in the mounting hole by glue. The glue connection can prevent the rubber nozzle 2 from coming out of the mounting hole.

[0019] The material of the catheter 1 is one of TPU, PE, PVC, and TPE. Soft materials such as TPU, PE, PVC, and TPE facilitate the bending of the catheter 1.

[0020] The material of the rubber nozzle 2 is halogenated butyl rubber, which can play a good sealing role.

[0021] The cross section of the conduit 1 is elliptical, which facilitates the layout and bending of the inner pipeline of the conduit 1.

[0022] The nozzle 2-3 is a rectangular channel, which can control the spraying range of the medicine.

[0023] When the utility model is used, the double syringe is inserted into the syringe outlet 1-3, the catheter 1 is bent and adjusted to a direction convenient for drug administration, the syringe is pushed to make the drug liquid flow into the drug liquid channel 1-2, and then enter the drug liquid pipeline 2-1 on both sides of the rubber nozzle 2, and the drug liquid is continuously squeezed to pass through the slit 2-2. After the two drug liquids pass through the slit 2-2, they are fully mixed and sprayed out from the nozzle 2-3.

[0024] The liquid medicine needs pressure to flow out through the slit 2-2. If the syringe is not used temporarily after installation, the slit 2-2 can prevent the liquid medicine from mixing in advance and prevent the liquid medicine from leaking.
