[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0039] like Figures 1 to 6 As shown, an umbilical vein catheter fixing device comprises:
[0040] A protective cover 1, wherein a cavity is provided in the protective cover 1;
[0041] A connecting plate 2, the connecting plate 2 is fixedly mounted on the opening end of the protective cover 1;
[0042] A connecting pipe 3, the connecting pipe 3 is connected to the cavity of the protective cover 1, the connecting pipe 3 is located on the end surface of the protective cover 1 away from the opening end, and is coaxially arranged with the protective cover 1, a plurality of grooves 301 are formed on the end surface of the connecting pipe 3 away from the protective cover 1, and an external thread is formed on the outer wall of the connecting pipe 3;
[0043] The fixing nut 4 has a threaded hole 403 and a tapered hole 404 connected in sequence on its inner side. The diameter of the tapered hole 404 at one end away from the threaded hole 403 is smaller than the diameter of the other end of the tapered hole 404. The fixing nut 4 is threadedly connected to the connecting pipe 3.
[0044] The inner diameter of the connecting tube 3 is larger than the outer diameter of the umbilical vein catheter 5, and the diameter of the tapered hole 404 near the threaded hole 403 matches the diameter of the threaded hole 403. The lower end surface of the connecting plate 2 is in the same plane as the end surface of the open end of the protective cover 1; the connecting plate 2 is a structural member made of silicone material, and there are two connecting plates 2. Both connecting plates 2 are provided with strip-shaped mounting holes 202, and straps are provided in the strip-shaped mounting holes 202. The straps are convenient for fixing the device on the patient's torso. In actual use, the device can be fixed with straps, or with adhesive tape, or with both adhesive tape and straps, which expands the scope of application of the device. The connecting plate 2 made of silicone material can be deformed to facilitate fixing to the patient's torso.
[0045] A positioning groove 201 is formed on the upper end surface of the connecting plate 2. Adhesive tape is pasted in the positioning groove 201 to facilitate the positioning of the tape and prevent the tape from falling off.
[0046] The outer edge of one end of the connecting tube 3 away from the protective cover 1 adopts a chamfered structure. The chamfered structure of the connecting tube 3 facilitates deformation of the connecting tube 3 at the groove 301 when the conical hole 404 squeezes the connecting tube 3.
[0047] A handle 401 is fixedly provided on the side wall of the fixing nut 4 , and the handle 401 is convenient for rotating the fixing nut 4 .
[0048] An anti-rotation plate 402 is provided at one end of the fixing nut 4 adjacent to the protective cover 1, and an anti-slip pattern 1 is provided on the end face of the anti-rotation plate 402 adjacent to the protective cover 1, and the protective cover 1 is provided with an anti-slip pattern 2 corresponding to the anti-slip pattern 1. The anti-rotation plate 402 presses the protective cover 1 tightly, and the anti-rotation plate 402 prevents the fixing nut 4 and the connecting pipe 3 from relative rotation, thereby improving the stability of the device during use.
[0049] The protective cover 1 is a transparent structural member. The protective cover 1 is a structural member made of acrylic material, or a structural member made of glass. The transparent protective cover 1 is convenient for observing the connection between the umbilical vein catheter 5 and the umbilical cord, and timely discovering whether there is bleeding or other problems.
[0050] A vent hole 101 communicating with the cavity is provided on the side wall of the protective cover 1. The vent hole 101 facilitates the drying of the umbilical cord in the cavity and prevents inflammation of the umbilical cord caused by poor air circulation.
[0051] Working process:
[0052] When this solution is implemented, the umbilical vein catheter 5 is passed through the fixing nut 4, the connecting tube 3, and the protective cover 1, and the umbilical vein catheter 5 is connected to the patient's umbilical cord. The position of the protective cover 1 is moved so that the lower end surface of the connecting plate 2 fits the patient's trunk, and then the protective cover 1 is fixed with a bandage, and then the protective cover 1 is fixed with an adhesive tape, and finally the fixing nut 4 is tightened, and then under the guidance of the tapered hole 404 of the fixing nut 4, the connecting tube 3 at the groove 301 moves inward to press the umbilical vein catheter 5, which plays a role in fixing the umbilical vein catheter 5. Compared with the traditional adhesive tape fixing of the umbilical vein catheter 5, the connecting plate 2 is connected to the patient's trunk, and the umbilical vein catheter 5 is connected to the protective cover 1 through the connecting tube 3, and the fixing effect is better, and the protective cover 1 plays a protective role, preventing accidental contact with the umbilical cord and improving the safety during the infusion process. The joint of the umbilical vein catheter 5 using this device is perpendicular to the patient's trunk, which is more convenient to connect, and there is no stress between the umbilical vein catheter 5 and the umbilical cord.
