The invention discloses an infusion apparatus capable of realizing blood returning resistance. The problems that the production cost is high, the manufacturing accuracy requirements ate high, the riskof infusion tube blockage exists, and needle puncture to observe blood returning is inconvenient in the prior art are mainly solved. The infusion apparatus comprises cork puncture needles, a murphy dropper air inlet pipes, a first infusion tube, air filters, a flow regulator, a second infusion tube, an intravenous infusion tube, an intravenous infusion needle and a non-return valve. The non-return valve comprises a valve body with the upper end connected with the first infusion tube, a valve core cavity, a valve core ball, a liquid inlet hole, a liquid outlet hole and a bracket, wherein the valve core cavity is arranged in the valve body and is in a cone shape, the valve core ball is arranged in the valve core cavity and is hollow, the liquid inlet hole is formed in the top of the valve core cavity, the liquid outlet hole is formed in the bottom of the valve core cavity, and the bracket is arranged at the bottom of the valve core cavity, connected to the edge of the top of the liquidoutlet hole in a spanned mode and in a cross shape. The infusion apparatus capable of realizing blood returning resistance has the advantages of simple structure, low processing accuracy requirement,low production cost, convenient and quick use and the like, and has very high practical value and popularizing value in the field of medical apparatus and instruments.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to an infusion set for realizing anti-blood regurgitation. Background technique [0002] The infusion set is a common disposable medical consumable used for sterile treatment of intravenous infusion and establishing a channel between the vein and the liquid medicine. It is mainly composed of a Murphy's dropper, a cork puncture needle, an infusion tube, a flow regulator, an intravenous infusion needle, an intravenous infusion tube, an air intake tube, and an air filter connection. The speed of the infusion was adjusted by the flow regulator, and the flow rate was observed with the Murphy's dropper. [0003] When using the infusion set, on the one hand, in order to facilitate the medical staff to confirm that the intravenous infusion needle enters the venous blood vessel accurately, it is necessary to observe the phenomenon of blood return in the intravenous infusion tube, so as to p...
