[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0021] like Figure 1-Figure 3As shown, an indwelling needle for injection provided in this embodiment includes an injection tube 1, a catheter 9 is arranged at one end of the injection tube 1, a needle 7 is arranged in the injection tube 1, and a needle holding handle 5 is connected to one end of the injection tube 1. A rotating chamber 11 is opened in the needle holding handle 5, a rotating shaft 13 is installed in the rotating chamber 11, an extension rod 6 is fixed on the rotating shaft 13, a magnetic block 2 12 is installed on one side wall of the extension rod 6, a magnetic block 10 is arranged in the rotating chamber 11, and the position of the magnetic block 10 corresponds to the position of the rotating magnetic block 2 12 of the extension rod 6.

[0022] The catheter 9 is formed on the injection tube 1, and the needle 7 passes through the catheter 9. The surface of the catheter 9 is formed with scale lines 8. The scale lines 8 are convenient for medical staff to observe the insertion depth to avoid discomfort to the patient.

[0023] The needle holding handle 5 is fixedly connected to the injection tube 1 , and a rotating cavity 11 is formed on the needle holding handle 5 , and the rotating cavity 11 provides a rotating space for the extension rod 6 .

[0024] The rotating shaft 13 is rotatably connected to the rotating chamber 11, and the extension rod 6 is fixedly connected to the rotating shaft 13. The extension rod 6 can be flipped under the action of the rotating shaft 13, and then adjusted to a vertical state during the acupuncture process, and adjusted to a horizontal state when in use, without increasing the occupied space of the device.

[0025] The second magnetic block 12 is fixedly connected to the extension rod 6, and the first magnetic block 10 is fixedly connected to the rotating chamber 11. The magnetic properties of the first magnetic block 10 and the second magnetic block 12 are opposite. The combination of the first magnetic block 10 and the second magnetic block 12 can adsorb and fix the extended rod 6 after rotation.

[0026] A guide tube 2 is connected to one side wall of the injection tube 1. The guide tube 2 is a transparent structure and can guide the drug solution.

[0027] One end of the guide tube 2 is connected to a positive pressure tube 3, and one end of the positive pressure tube 3 is formed with a positive pressure valve 4. The medicine bottle is connected to the positive pressure valve 4, and the medicine is then input into the patient's body through the positive pressure tube 3, the guide tube 2 and the catheter 9.

[0028] Working principle of the device: During the use of the device, when the medical staff holds the needle, the extension rod 6 can be flipped in the rotating chamber 11 under the action of the rotating shaft 13, and after flipping, it can be fixed by the attraction between the magnetic block 10 and the magnetic block 2 12. The extension rod 6 can increase the handholding area of ​​the medical staff, thereby facilitating the operation of the medical staff and ensuring the stability during the needle. After the needle is completed, the extension rod 6 is folded to ensure that it does not take up space, and then the medicine bottle is connected to the positive pressure valve 4. At this time, the medicine is input into the patient's body through the positive pressure tube 3, the guide tube 2 and the catheter 9.

[0029] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
