Problems solved by technology

Due to the use of inclined plane sealing, the sealing surface is large, which will lead to the disadvantage of dead sealing. When the first infusion is completed, when the second infusion is performed, the floating body cannot drive the sealing body to rise due to insufficient buoyancy or other reasons. Squeeze the dropper with your hand to remove the gas in the dropper. The dropper sucks the liquid in the bottle. In principle, the floating body floats up by its own buoyancy. However, when squeezing the dropper, press up and down to make the lower seal tighter. It is also necessary to shake the dropper so that the sealing body is separated from the bottom of the dropper. This operation is more time-consuming and easily leads to damage to the sealing body; how to reduce the dressing change time of medical staff and the patient's ability to It is very important to change the medicine independently

no. 1 example

[0032] refer to figure 1 ,like figure 1 A kind of automatic stop liquid drop bucket shown, comprises casing 1, floating body 2 and sealing body 3, wherein, described sealing body 3 is connected under floating body 2, and is placed in casing 1; Said sealing body 3 and The lower end of the housing 1 is sealed with an inclined surface to further strengthen the sealing of the dropping funnel; the upper end of the floating body 2 is provided with a handle 4; in order to prevent the sealing body 3 from rising due to the buoyancy of the liquid during the second infusion, a handle 4 is formed at the upper end. On the table top, as long as the hollow part of the dropping funnel is pressed, the pressure on the handle table top makes the sealing body 3 break away from the slope seal and enter the normal infusion.

Abstract

The invention discloses a self-stopping dropping funnel and an infusion set comprising same. The self-stopping dropping funnel comprises a housing, a floating body and a sealing body, wherein the sealing body is connected at the lower surface of the floating body and arranged in the housing; the sealing body is sealed with the lower inclined surface of the housing; the self-stopping dropping funnel is characterized in that a lifting handle is arranged at the upper end of the floating body. With the aim of realizing continuous use, the self-stopping dropping funnel can be automatically sealed when an infusion bottle is exchanged and the infusion is to be finished, and can be automatically lifted during a secondary infusion process to prevent the air from entering the body of a patient, prevent repeated operation and avoid returning blood, thereby improving the reliability of sealing the infusion pipeline and further improving the safety. The invention discloses the self-stopping dropping funnel which is provided with a good blocking effect and is capable of conveniently removing the blocking to realize continuous use, as well as the infusion set comprising the self-stopping dropping funnel.

Description

technical field [0001] The invention relates to a medical device for intravenous transfusion for clinical patients, in particular to an automatic liquid-stop dripping funnel and an infusion set with the dripping funnel. Background technique [0002] When carrying out intravenous infusion to patient at present, widely use disposable infusion set, mainly by bottle stopper piercer, air inlet device, dropping funnel, flow regulator, medicinal liquid filter, venous infusion needle and some connecting conduits. Under the action of atmospheric pressure, the liquid in the bottle flows into the drip funnel along the thinner infusion hose, and when the water column pressure in the drip funnel is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose. During the infusion process, the attendant needs to pay close attention to the liquid level of the liquid medicine. Otherwise, when the liquid level of the liquid medicine falls to the lower end of t...
