[0013] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments. However, the specific implementation methods and embodiments described below are only for illustrative purposes and are not intended to limit the present invention.

[0014] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate directions or positional relationships based on the attached text. Figure 1 The directions or positional relationships shown are only for the convenience of describing the present invention, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0015] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0016] In order to solve the above technical problems, Figure 1-2As shown, the utility model designs a medical needle protection device, including a needle 1, a needle fixing seat 2, and a protective sleeve 3. The needle 1 is fixedly mounted on one end of the needle fixing seat 2. The upper part of the needle fixing seat 2 is provided with a first limiting plate 4 that protrudes radially outward. The protective sleeve 3 includes a cylindrical support portion 31 and an outer baffle 32. The outer baffle 32 is arranged above the cylindrical support portion 31. The cylindrical support portion 31 of the protective sleeve 3 is sleeved on the outside of the needle fixing seat 2 and its top end contacts the first limiting plate 4. The needle fixing seat 2 is also connected to a second limiting plate 5. The second limiting plate 5 is provided on the upper part of the needle fixing seat 2. The second limiting plate 5 is arranged opposite to the first limiting plate 4. The cylindrical support portion 31 of the protective sleeve 3 is located between the first limiting plate 4 and the second limiting plate 5. The outer baffle 32 of the protective sleeve 3 can effectively cover the top of the needle fixing seat 2, thereby preventing the liquid at the needle hole position from overflowing before the needle 1 is connected to the catheter, reducing the potential contamination risk to patients and medical staff, and reducing the additional cleaning and disinfection work caused by contamination. The setting of the first limiting plate 4 and the second limiting plate 5 provides stable support for the protective sleeve 3, ensuring the stability and reliability of the device during use.

[0017] Furthermore, the outer surface of the needle fixing seat 2 is provided with an external thread, and the inner hole of the second limiting plate 5 is provided with an internal thread adapted to the external thread. The second limiting plate 5 is detachably connected to the needle fixing seat 2 by a threaded connection. The threaded connection method makes the connection more stable and the assembly is also more convenient, so that each component can be stored and used separately, and whether to install it can be selected according to actual conditions, thereby increasing the flexibility of use. The outer surface of the second limiting plate is preferably provided with anti-slip grooves to increase friction and avoid slipping when twisting.

[0018] Furthermore, the outer wall of the needle fixing seat 2 is also provided with a plurality of radial limiting protrusions 6 evenly spaced along the circumferential direction, and the inner hole wall of the cylindrical support portion 31 of the protective sleeve 3 is provided with a plurality of limiting grooves adapted to the limiting protrusions 6. The cooperation between the limiting protrusions 6 and the limiting grooves can enable the protective sleeve 3 to be stably mounted on the outside of the needle fixing seat 2.

[0019] Furthermore, the protective cover 3 is made of a transparent plastic material, which has a stable structure and provides a good visual effect without affecting the medical staff's observation of the needle 1 status.

[0020] Furthermore, the cylindrical support portion 31 and the outer baffle 32 are integrally formed, which enhances the overall structural strength of the device, makes it more durable, reduces the risk of failure due to loose structure, and reduces the cost of use.

[0021] The medical needle 1 protection device can effectively prevent the overflow of liquid from the needle hole, reduce the risk of infection for patients and medical staff, reduce the pollution of the medical environment, and improve the safety and hygiene of medical operations.

[0022] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
