Medical venous indwelling needle convenient for blood circulation

Abstract

The invention discloses a medical venous indwelling needle convenient for blood circulation in the technical field of medical injection devices. The medical venous indwelling needle comprises a diversion cavity, wherein fixing straps are arranged on the upper and lower sides of the diversion cavity; rotating rods are movably clamped with the interiors of the two sides, close to one sides, of the diversion cavity; the rotating rods are fixed to the side walls of the fixing straps; an energy storage spring is sleeved to the two ends of each rotating rod; the two ends of the rotating rods are movably connected with the inner wall of the diversion cavity through the energy storage springs; a connector is arranged at the upper end of the fixing strap at the top; a fixed clamping block is arranged on the side surface of the connector; a rotating pin is arranged at one end of the fixed clamping block; one end of the fixed clamping block is movably connected with one end of the side surface ofthe connector through the rotating pin; a clamping groove is formed in the side surface of the fixed clamping block. The medical venous indwelling needle is simple in structure and convenient to use,and ensures that the transfusion effect is better through fixing to a device and adjustment of a diversion tube.

Description

technical field [0001] The invention relates to the technical field of medical injection devices, in particular to a medical venous indwelling needle for blood circulation. Background technique [0002] The application of intravenous indwelling needles is a better method for clinical infusion. On the one hand, it can reduce the pain caused by repeated scalp needle punctures in infants and young children and can be applied to adults with long-term infusions. On the other hand, it also reduces the workload of clinical nurses; if the indwelling time of intravenous indwelling needle is short, it can reach 27 days for the elderly. Zhao Gaiting suggested to keep it for 96 hours through animal experiments. Qi Hong believes that it is completely feasible to leave it for 7 days as long as the puncture site is kept relatively sterile and the surrounding skin is clean, as long as there is no blockage and leakage. Li Xiaoyan et al. observed 50 patients with indwelling trocars for an av...

Problems solved by technology

[0005] The purpose of the present invention is to provide a medical venous indwelling needle that is convenient for blood circulation, to solve the problem that a large amount of medical tape will be wasted when the existing venous indwelling needle proposed in the above-mentioned background technology is used, and at the same time, the indwelling needle is fixed by using medical tape , it also needs to be replaced regularly with medical tape, which is very inconvenient, and there is no good way to fix the drainage tube, and it is easy to cause the problem of blood backflow
