The dropping funnel capable of automatically reducing transfusion blood return comprises a blood return reducing device, wherein the blood return reducing device comprises a cavity, a guide rail, and a sealing sliding block capable of sliding up and down along the guide rail, a first interface and a second interface.
When the infusion device is used, the first interface is fixedly connected with the liquid inlet pipe, the second interface is fixedly connected with the infusion pipe, the injection liquid enters the cavity through the first interface, the injection liquid is accumulated in the cavity, and the liquid level in the cavity is gradually increased. At this time, because the density of the sealing slide block is smaller than that of the injection liquid, the sealing slide block ascends along the guide rail, the second interface closed by the sealing slide block 105 is opened, the injection liquid enters the infusion tube from the second interface until the injection liquid in the infusion bottle is exhausted, the liquid level in the cavity gradually descends, the sealing slide block slides downwards, the second interface is automatically closed, and the injection liquid in the infusion tube can enter the blood vessel until the internal pressure and the external pressure are balanced.
Blood returns in the infusion process, the injection can enter the cavity from the second interface, the injection is accumulated in the cavity, and the liquid level in the cavity is gradually increased. At this time, because the sealing slide block density is less than injection density, the sealing slide block rises along the guide rail until the sealing slide block contacts the top end of the cavity, the first interface is automatically closed, and blood return is stopped after the cavity is filled.
