DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] A venous indwelling needle fixator, such as Figure 1-Figure 4 As shown, it includes a positive pressure connector 1, and a fixing mechanism 2 is provided on the rear side of the positive pressure connector 1 for fixing the intravenous indwelling needle;

[0024] The fixing mechanism 2 includes a mounting plate 21, a support frame 22, a fixing belt 23, a positioning clamp block 28, a positioning clamp rod 210 and a clamp angle block 211;

[0025] The support hoop frame 22 is located at the rear side below the positive pressure connector 1, and is used to support the bottom of the positive pressure connector. The rear side of the support hoop frame 22 is slidably connected with a mounting plate 21 for mounting the support hoop frame 22 and the positioning clamp 28. The rear side of the mounting plate 21 is fixedly connected with an adhesive sheet 26 for pasting the fixing mechanism to the patient's skin. The upper part of the mounting plate 21 is slidably connected with a positioning clamp 28 for limiting the upper part of the positive pressure connector. One end of the front side of the support hoop frame 22 and the positioning clamp 28 is fixedly connected with a fixing belt 23 for fixing the front side of the positive pressure connector 1. A positioning rod 210 is provided at the upper and lower ends of one end of the fixed belt 23, which is used to fix the adjusted positioning clamp 28 and the support clamp frame 22. A clamp corner block 211 is fixedly connected to the middle of the other end of the support clamp frame 22 and the positioning clamp 28, which is used to fix one end of the fixed belt 23. Both ends of the adhesive sheet 26 are fixedly connected with multiple adhesive strips 27, which are used to fix the four corners of the adhesive sheet 26 to prevent the four corners of the adhesive sheet 26 from curling. A plurality of fixing holes 25 are opened on the fixing belt 23, and the size of the fixing hole 25 matches the size of the clamp corner block 211 after being squeezed and folded.

[0026] It should be pointed out that when the clamp is fixed, the support clamp frame 22 is slid to the bottom of the slide groove 24, and then the positioning clamp rod 210 provided on the support clamp frame 22 is pressed, so that the positioning clamp rod 210 is clamped into the positioning clamp hole at the corresponding position in the slide groove 24. After the triangular block provided on the positioning clamp rod 210 is pushed into the positioning clamp hole, the smooth block at the connection position between the triangular block and the positioning clamp rod 210 blocks the positioning clamp hole, and then the bottom of the positive pressure joint is clamped to the top of the support clamp frame 22, so that the auxiliary pipe 5 is clamped to the arc-shaped support block fixed at one end of the support clamp frame 22, and then the positioning clamp block 28 is slid so that the positioning clamp block 28 slides along the slide groove 24 from the top and bottom of the slide groove 24 to the bottom of the slide groove 24. When the positioning clamp block 2 When the top of the inner side of 8 contacts the top of the positive pressure connector 1, stop sliding the positioning clamp 28 down, and the positioning clamp 28 will half-wrap the upper part of the positive pressure connector 1, and the V-shaped block fixed at one end of the positioning clamp 28 will be stuck to the V-shaped corner of the auxiliary pipe, and then press the positioning clamp rod 210 provided on the positioning clamp 28, so that the positioning clamp rod 210 is stuck in the positioning clamp hole provided at the corresponding position, and the adjusted position of the positioning clamp 28 is fixed, and then pull the fixing belt 23, so that the fixing belt 23 is attached to the front surface of the positive pressure connector 1, and go around to the position of the clamp angle block 211, and the corresponding fixing hole 25 on the fixing belt 23 is stuck to the clamp angle block 211, and the clamp angle block 211 fixes one end of the fixing belt 23;

[0027] When the positive pressure connector 1 is fixed, the protective film behind the adhesive sheet 26 is removed and the adhesive sheet 26 is attached to the designated position of the patient's skin, and then the protective film on the rear side of the adhesive tape 27 is removed and smoothed and attached to the skin.

[0028] See also Figure 1 and Figure 2 A slide groove 24 is provided at the connection between the two ends of the rear side of the support hoop frame 22 and the front surface of the mounting plate 21. Two sliders are slidably connected to the inner side of the slide groove 24. One of the two sliders is fixedly connected to the support hoop frame 22, and the other slider is connected to the positioning clamp 28. A plurality of indicator strips 29 are provided at one end of the slide groove 24, and a plurality of fixed card holes are provided in the middle of the inner rear surface of the slide groove 24. The number of the indicator strips 29 matches the number of the fixed card holes, and the spacing between the indicator strips 29 is the same as the spacing between the fixed card holes.

[0029] It can be understood that when sliding and adjusting the support hoop frame 22 and the positioning clamp block 28, the positioning rod 210 provided on the sliding support hoop frame 22 and the positioning clamp block 28 is always facing the indicator bar 29, so that the positioning hole provided on the adjusted position is just located below the positioning rod 210, which is convenient for the positioning rod 210 to fix the adjusted position of the support hoop frame 22 and the positioning clamp block 28. When the support hoop frame 22 and the positioning clamp block 28 slide, the sliding groove 24 and the slider guide the sliding trajectory of the support hoop frame 22 and the positioning clamp block 28.

[0030] See also Figure 1 , Figure 2 and Figure 4 , protective sponges are fixedly connected to the inner surfaces of the positioning clamp block 28 and the support clamp frame 22, the spacing between the fixed clamp holes matches the spacing between the positioning clamp rods 210 provided on the positioning clamp block 28 and the spacing between the positioning clamp rods 210 provided on the support clamp frame 22, an extension tube 3 is fixedly connected to the middle of the bottom end of the positive pressure joint 1, a needle 4 is fixedly connected to one end of the extension tube 3, and a secondary tube 5 is fixedly connected to the lower part of one end of the positive pressure joint 1.

[0031] It can be understood that when the positioning clamp 28 and the support clamp frame 22 are clamped onto the positive-pressure connector 1 and the auxiliary pipe 5, the protective sponge fixedly connected to the inner side of the positioning clamp 28 and the support clamp frame 22 will directly contact the outer surfaces of the positive-pressure connector 1 and the auxiliary pipe 5, preventing the positioning clamp 28 and the inner wall of the support clamp frame 22 from directly contacting the outer surfaces of the positive-pressure connector 1 and the auxiliary pipe 5, squeezing the outer surfaces of the positive-pressure connector 1 and the auxiliary pipe 5, and causing certain damage to the positive-pressure connector 1 and the auxiliary pipe 5.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
