DETAILED DESCRIPTION

[0017] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a subcutaneous injection scalp needle of the present invention in conjunction with the accompanying drawings.

[0018] Example 1 like Figures 1 to 10 As shown, a subcutaneous scalp injection needle of the present invention comprises a fixing base 1, a support base 2, and a scalp needle 3. The support base 2 is wedge-shaped, and the upper surface of the support base 2 forms an angle of 30° to 40° with its bottom surface. In actual production, three angles can be selected: 30°, 35°, and 40°.

[0019] like Figure 4 As shown, the surface of the mounting base 1 is provided with an adhesive layer made of the same material as medical tape. The mounting base 1 is shaped like an "X" (a cross), allowing for insertion of the puncture needle 3 in the center. The adhesive layer allows the mounting base 1 to be adhered to the patient's skin. The mounting base 1 is provided with a first securing buckle 11 and a second securing buckle 12, which are connected to the support base 2. The wedge-shaped surface of the support base 2 is provided with an arcuate groove 22 for securing the puncture needle 3.

[0020] like Figure 11 As shown, a fixing belt 21 is movably provided on the support base 2, and a fixing opening is provided on the support base 2. The fixing belt 21 is connected to the first fixing buckle 11, and the fixing opening is connected to the second fixing buckle 12. The fixing belt 21 is provided with a plurality of holes. The first fixing buckle 11 is frame-shaped, and its inner side is provided with protrusions that match the holes of the fixing belt 21.

[0021] like Figure 12 As shown, the second fixing buckle 12 is sheet-shaped with a protrusion on the surface, and the rear end of the support base 2 is provided with a card hole 251 that matches the protrusion. The first fixing buckle 11 and the second fixing buckle 12 have been used in common fixing structures such as binding belts.

[0022] When in use, the fixing base 1 is attached to the patient, and the supporting base 2 is fixed on the fixing base 1, and the skin needle 3 is pushed into the patient's skin along the arc groove 22, and the skin needle 3 is fixed to the supporting base 2 with tape.

[0023] The device of this embodiment solves the problem of poor fixation of scalp needles during long-term subcutaneous injections. The angle of the wedge-shaped support 2 is used to fix the insertion angle, alleviate the patient's pain, and improve the patient experience.

[0024] Example 2 In this embodiment, if Figure 3 As shown, the skin needle 3 is provided with a needle 32 and a handle 31, and the tail of the skin needle 3 is connected to a hose that is communicated with the needle 32. Medical staff can conveniently hold the handle 31 for operation.

[0025] Example 3 In this embodiment, if Figure 5 As shown, a clamping plate 24 is movably provided on the support base 2. One side of the clamping plate 24 is connected to one side of the support base 2 via a rotating shaft and can rotate relative to it. A recess is provided at the bottom of the support base 2 to accommodate the clamping plate 24 and the fixing belt 21. The fixing belt 21 is clamped between the clamping plate 24 and the base of the support base 2. The position of the fixing belt 21 is fixed by friction through the clamping of the clamping plate 24 and the support base 2. During use, by opening and closing the clamping plate 24, the support base 2 can be moved laterally on the fixing belt 21 to adjust the position of the front end of the support base 2. During use, when the second fixing buckle 12 is engaged with the support base 2, the support base 2 can be allowed to swing slightly around the second fixing buckle 12 to adapt to the use environment.

[0026] In actual use, the fixing belt 21 can be used alone without being fixed with the second fixing buckle 12, so as to facilitate the lateral movement of the support base 2 and facilitate use on parts of the human body with larger curved surfaces.

[0027] In actual use, if the patient's local position is not convenient to be fixed using the fixing seat 1, the patient can be tied to the patient through a longer fixing belt 21, and then the support seat 2 is fixed on the fixing belt 21.

[0028] Example 4 In this embodiment, if Figure 5 、 Figure 7 and Figure 9 As shown, the retaining plate 24 is provided with limiting plates 241 on both sides, each of which is provided with limiting holes 243 and positioning clamps 244. The support base 2 is provided with several anti-slip strips 242, which also have a space to accommodate the retaining plate 24 and the limiting plates 241. The anti-slip strips 242 and the retaining plate 244 work together to squeeze the fixing strap 21, preventing the fixing strap 21 from loosening.

[0029] When in use, the fixing belt 21 passes through the limiting hole 243 so that the fixing belt 21 and the supporting base 2 remain as a whole to prevent them from falling off.

[0030] The positioning clamp head 244 cooperates with the support seat 2 to prevent the clamping plate 24 from falling off.

[0031] Example 5 In this embodiment, if Figures 5 to 8 As shown, the bottom of the support base 2 is provided with several adjustment portions 25. These adjustment portions 25 are made of flexible rubber, one end of which is fixedly connected to the support base 2 and the other end of which is connected to an adjuster 27 movably mounted on the support base 2. By individually adjusting the position of each adjustment portion 25, the support base 2 can better adapt to the curvature of the human body surface at locations with larger curvatures, thereby increasing the contact area between the support base 2 and the skin and achieving better positioning. This also serves to control the angle of the skin needles 3.

[0032] Specifically, the adjusting portion 25 is a flexible surface. A support block 251 is provided on the adjusting portion 25 . The fixing port 251 is provided on the support block 251 . The adjuster 27 is connected to the support block 251 .

[0033] Specifically, the adjuster 27 is connected to the limit stopper 271 via a connecting rod 272. The connecting rod 272 is provided with a limit head 273. The support base 2 is provided with a limit slot 26. The connecting rod 272 is disposed on the limit slot 26. The limit heads 273 cooperate with the limit teeth 261 provided on both sides of the limit slot 26. By adjusting the position of the adjuster 27 within the limit slot 26, the extension of the push rod 28 is controlled, and the position of the support block 251 is further controlled.

[0034] The limiting baffle 271 is connected to the push rod 28 , and the push rod 28 is movably connected to the support block 251 .

[0035] Example 6 In this embodiment, if Figure 1 、 Figure 2 and Figure 5 As shown, an elastic fixing buckle 23 is provided on the support base 2. The elastic fixing buckle 23 is arc-shaped and cooperates with the arc-shaped groove 22 to hold the skin needle 3.

[0036] The elastic fixing buckle 23 is connected to an elastic mechanism 231, which is a soft steel sheet. The elastic mechanism 231 is connected to a fixing plate 232, which is rotatably mounted on the support base 2 via rivets.

[0037] Example 7 In this embodiment, each support block 251 of the adjustment portion 25 is provided with a fixing port, which is connected to the second fixing buckle 12 through the fixing port. In this embodiment, the purpose of adjusting the support base 2 can also be achieved by connecting the second fixing buckle 12 to fixing ports at different positions.

[0038] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
