[0034] As Figure 1 shown, an embodiment of the present utility model provides an anti - allergy and pressure - sore - prevention intravenous indwelling needle device, including a catheter connector base 1. A end cap 2 is installed on the side of the catheter connector base 1. A heparin cap 3 is installed at one end of the catheter connector base 1. A long catheter 4 is connected to the end of the catheter connector base 1 away from the end cap 2 and the heparin cap 3. The long catheter 4 is connected to a Y - shaped hose seat 5. A steel needle 6 for puncture is fixed at one end of the Y - shaped hose seat 5. And a needle - holding handle 7 is arranged on the side of the Y - shaped hose seat 5. An anti - allergy and pressure - sore - prevention sponge pad 8 is detachably installed on the lower end surface of the needle - holding handle 7.
[0035] AsFigure 2 As shown in Figure 3 Figure 3 , the anti-allergy and pressure ulcer prevention sponge pad 8 includes a fixing piece 801. A vertical fixing column 802 is fixed on the upper end surface of the fixing piece 801. A jack for inserting the fixing column 802 is provided on the needle holder 7. Specifically, in this embodiment, an external thread is configured on the fixing column 802, and an internal thread is configured on the inner wall of the jack on the needle holder 7, so that the fixing piece 801 can be detachably fixed by the threaded insertion of the fixing column 802 and the jack on the needle holder 7. Therefore, it is convenient to choose whether to install the anti-allergy and pressure ulcer prevention sponge pad 8 on the needle holder 7 for use according to actual needs.
[0036] In addition, a sponge layer 803 is detachably installed on the lower end surface of the fixing piece 801. Among them, in this embodiment, a hook surface portion 804 is provided in the middle of the lower end surface of the fixing piece 801, and a fluff surface portion 805 is provided on the upper end surface of the sponge layer 803. The fluff surface portion 805 is adhesively engaged with the hook surface portion 804. Therefore, in this embodiment, the structure of Velcro is used to detachably install the sponge layer 803. In other embodiments, other methods such as snap connection and glue pasting can also be used for detachable installation, aiming to facilitate the replacement of the sponge layer 803 to ensure hygiene, so that parts of the anti-allergy and pressure ulcer prevention sponge pad 8 other than the sponge layer 803 can be reused to reduce the use cost.
[0037] Specifically, the sponge layer 803 is made of sponge in line with medical specifications and is disinfected. It is cleaner than the cotton pad placed under the indwelling needle in the prior art and can greatly reduce the infection rate at the puncture site.
[0038] As shown in Figure 1 As shown in Figure 4 Figure 4 , a stop clamp 9 is sleeved on the long catheter 4. The stop clamp 9 is of a C-shaped structure. One end of the stop clamp 9 is a pressing portion 901, and an extrusion convex block 902 is configured on the inner wall of the stop clamp 9 corresponding to the pressing portion 901, so that the long catheter 4 can be squeezed and intercepted by pressing the extrusion convex block 902 to make it dock with the pressing portion 901, achieving the stop flow effect.
[0039] At the same time, in this embodiment, a positioning slot 903 is provided on the pressing portion 901. The other end of the stop clamp 9 faces the pressing portion 901, and a movable plug 904 is elastically inserted. The movable plug 904 is inserted and matched with the positioning slot 903. Specifically, a movable plug 904 is inserted at one end of the stop clamp 9 facing the pressing portion 901. A plug handle 906 is fixed at one end of the movable plug 904 away from the positioning slot 903. A spring 905 is connected between the plug handle 906 and the end of the stop clamp 9. Therefore, the elastic installation of the movable plug 904 and the positioning slot 903 can be used to conveniently keep the pressing portion 901 and the extrusion convex block 902 docked for continuous stop flow, without the need for medical staff to continuously press to maintain stop flow, which is convenient to use.
[0040] The working principle of the present utility model is as follows: When in use, according to actual needs, such as when puncturing a sensitive skin patient like a child with an intravenous indwelling needle, the anti-allergy and pressure ulcer prevention sponge pad 8 can be first fixed to the lower end surface of the needle holding handle 7 by using the fixing column 802. After successful puncture, it is convenient to use the sponge layer 803 of the anti-allergy and pressure ulcer prevention sponge pad 8 to contact the patient's skin, so that the sponge layer 803 can play the role of anti-allergy and pressure ulcer prevention, thereby better protecting the service life of the indwelling needle and the skin of sensitive skin patients such as children.
[0041] Meanwhile, when the indwelling needle device is in use, the flow stop clip 9 on the long catheter 4 can be used to stop the flow. The difference in the use effect compared with the existing flow stop device is that in this device, when using the pressing part 901 to press and cooperate with the squeezing convex block 902 to intercept and squeeze the long catheter 4, it is convenient to insert and cooperate with the positioning slot 903 opened at the end of the pressing part 901 through the movable pin 904. During the process of using the flow stop clip 9 to stop the flow, the movable pin 904 can be used for limiting, without the need for medical staff to continuously press the pressing part 901 to stop the flow, which is conducive to freeing the hands of medical staff for other nursing operations.
[0042] In summary, by setting the anti-allergy and pressure ulcer prevention sponge pad 8 on the lower end surface of the needle holding handle 7, the present device can effectively solve the problems that the existing intravenous indwelling needle is likely to cause red rashes and itching when used for sensitive skin patients such as children, and is also likely to cause skin pressure ulcers after long-term use. Moreover, the present device can also facilitate continuous flow stop operation, which is conducive to liberating the hands of medical staff that originally needed to continuously press to stop the flow, and the overall use effect is good.
