[0024] In a specific embodiment of the present invention, the prefilled flush syringe with a stable effect allows the user to directly hold the entire device through the grip assembly 1, and at the same time, the drug solution is poured into the injection assembly 3 for pre-filling. At this time, pressing the grip assembly 1 can cause the injection assembly 3 to inject the drug solution into the front injection needle 5. Under the pressure of the grip assembly 1, the drug solution will use the injection assembly 3 to flow from the injection needle 5 to the needle outlet 7, and then from the needle nozzle 8 to the needle connecting port 9 to complete the injection. The injection posture of this device only needs to hold the grip assembly 1, and will not cause any burden on the user's finger joints throughout the process, thereby further increasing the overall comfort of the user during the injection process.

[0025] Specifically, the grip assembly 1 includes a lower handle 101, an adapter frame 102, a first rotating shaft 103, an upper handle 104 and a thumb grip 105. The lower handle 101 is arranged on one side of the connecting ring 4, the adapter frame 102 is rotatably connected to one end of the lower handle 101, the first rotating shaft 103 is rotatably connected to the inner wall of the adapter frame 102, and the upper handle 104 is fixedly connected to the surface of the first rotating shaft 103.

[0026] In a specific embodiment of the present invention, the grip assembly 1 supports the entire device through the lower handle 101, and the adapter frame 102 can drive the first rotating shaft 103 to rotate, thereby ensuring the range of motion of the upper handle 104, and the upper handle 104 and the lower handle 101 are both adapted to the base of the thumb of the human hand, thereby helping the user to hold the grip assembly 1 more comfortably for use, thereby further improving the overall comfort of the device.

[0027] Specifically, the thumb grip 105 is fixedly connected to the top of the upper top handle 104 , and the thumb grip 105 matches the upper top handle 104 .

[0028] In a specific embodiment of the present invention, the thumb grip 105 can provide a fulcrum for the thumb when the user tightly grips the grip assembly 1 , thereby further improving the comfort of the grip assembly 1 .

[0029] Specifically, the injection assembly 3 includes a second rotating shaft 301, a rotating shaft fixing cap 302, a pushing hook 303, a protective liquid infusion column 304 and a hook moving handle 305. The second rotating shaft 301 is rotatably connected to the top inner side of the handle assembly 1, and multiple rotating shaft fixing caps 302 are fixedly connected to both sides of the second rotating shaft 301.

[0030] In a specific embodiment of the present invention, the injection assembly 3 is connected to the top inner wall of the handle assembly 1 through the second rotating shaft 301. Therefore, when the user holds the handle assembly 1, the second rotating shaft 301 will also rotate under the action of the handle, thereby driving the rotating shaft fixing cap 302 to rotate.

[0031] Specifically, the pushing hook 303 is fixedly connected to the surface of the second rotating shaft 301, the protective liquid infusion column 304 is arranged on the inner side of the bottom of the handle assembly 1, the hook moving handle 305 is fixedly connected to the surface of the protective liquid infusion column 304, and the hook moving handle 305 matches the pushing hook 303.

[0032] In a specific embodiment of the present invention, the pushing hook 303 will rotate under the rotation of the second rotating shaft 301. At this time, the protective liquid infusion column 304 and the hook moving handle 305 are at the bottom of the pushing hook 303, and the protective liquid infusion column 304 and the hook moving handle 305 are slidably connected to the bottom of the handle assembly 1. Therefore, the rotation of the pushing hook 303 will become to push the protective liquid infusion column 304 and the hook moving handle 305 forward, thereby completing the injection of the drug solution. During the process, you only need to hold the handle assembly 1, which will further improve the overall comfort and injection efficiency of the device.

[0033] Specifically, the anti-slip cover 2 is fixedly connected to the top of the handle assembly 1 , and the anti-slip cover 2 matches the handle assembly 1 .

[0034] In a specific embodiment of the present invention, the anti-slip cover 2 can help the user prevent the hand from slipping when using the handle assembly 1, thereby further improving the overall safety of the device.

[0035] Specifically, the label box 6 is fixedly connected to the surface of the injection needle tube 5 .

[0036] In a specific embodiment of the present invention, the label box 6 can be replaced at any time to remind the user of the type of liquid medicine, thereby further improving the overall safety performance of the device.

[0037] Working principle: This kind of stable prefilled flush syringe allows the user to hold the whole device directly through the grip assembly 1, and at the same time, the drug solution is poured into the injection assembly 3 for prefilling. At this time, pressing the grip assembly 1 can make the injection assembly 3 inject the drug solution into the injection needle tube 5 in front. Under the pressure of the grip assembly 1, the drug solution will be injected from the injection needle tube 5 to the needle tube outlet 7 through the injection assembly 3, and then from the needle tube nozzle 8 to the needle tube connection port 9 to complete the injection. The injection posture of this device only needs to hold the grip assembly 1, and there is no need to touch the needle tube 5 during the whole process. The user's finger joints are not burdened, thereby further increasing the overall comfort of the user during the injection process. The grip assembly 1 supports the entire device through the lower bottom handle 101, and the adapter frame 102 can drive the first rotating shaft 103 to rotate, thereby ensuring the range of motion of the upper top handle 104, and the upper top handle 104 and the lower bottom handle 101 are both adapted to the base of the thumb of the human hand, so it can help the user to hold the grip assembly 1 more comfortably for use, further improving the overall comfort of the device, and the thumb grip 105 can be used when the user tightly grasps the grip assembly The second rotating shaft 301 is connected to the top inner wall of the grip assembly 1, so when the user holds the grip assembly 1, the second rotating shaft 301 will also rotate under the action of the grip, thereby driving the rotating shaft fixing cap 302 to rotate, and the pushing hook 303 will rotate under the rotation of the second rotating shaft 301. At this time, the protective liquid infusion column 304 and the hook moving handle 305 are at the bottom of the pushing hook 303, and the protective liquid infusion column 304 and the hook moving handle 305 are at the bottom of the pushing hook 303. The handle 305 is slidably connected to the bottom of the grip assembly 1, so that the rotation of the pushing hook 303 will push the protective liquid infusion column 304 and the hook moving handle 305 forward to complete the injection of the drug solution. During the process, only the grip assembly 1 needs to be held, which will further improve the overall comfort and injection efficiency of the device. The anti-slip cover 2 can help the user prevent the hand from slipping when using the grip assembly 1, further improving the overall safety of the device. The label box 6 can be replaced at any time to remind the user of the type of drug solution, further improving the overall safety performance of the device.
