Anticoagulation liquid-stopping transfusion device with liquid-stopping sealant floating plug balloon catheter

Abstract

The invention discloses an anticoagulation liquid-stopping transfusion device with a liquid-stopping sealant floating plug balloon catheter, which comprises a bottle stopper puncture device, an upper infusion tube, a droplet bucket, a lower infusion tube, a flow regulator, an outer cone connector, a capillary infusion tube, a flank and an intravenous injection needle. The transfusion device is characterized in that the transfusion device also comprises a liquid storage capsule that has a lower neck provided with an exhaust pipe upward, and has a liquid-guiding aperture on a lower collet; a liquid-stopping sealant floating plug balloon catheter set below the liquid storage capsule; a drainage tube that connects the liquid-guiding aperture and the second protruding pipe below the liquid-stopping sealant floating plug balloon catheter; an anti-bubble tube set in the lower infusion tube; and a flow transposing device set between the liquid-guiding aperture and the second protruding pipe that can convert the transfusion flow from microfluidic to non-microfluidic. According to the invention, the transfusion device can stop the liquid automatically; when the liquid is stopped, the blood clotting block won't be generated at the intravenous route needle place because of long off time; and the waste of transfusion in the liquid storage capsule because of short liquid stopping time is avoided; besides, the air is prevented from getting into the lower infusion tube.

Description

【Technical field】 [0001] The invention relates to a one-time use infusion set, and is especially suitable for a one-time use anticoagulant hemostatic liquid infusion set. 【Background technique】 [0002] At present, some liquid stopper infusion devices, after stop liquid start, just do not have transfusion to be transfused into the vein under the intravenous injection needle again. In general patients, after a period of hemostasis, if there is no nurse to deal with it, there will be blood clots at the intravenous injection needle; in addition, almost all severe patients with diseases will cause blood coagulation disorders, if this This kind of patient uses stop liquid infusion set, after stop liquid, in a short time, blood coagulation will take place in intravenous injection needle. Once a blood clot occurs, it will panic the patient and even cause disputes between doctors and patients. [0003] In order to overcome the above-mentioned defects, a liquid storage bag is arran...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned deficiencies of the hemostatic infusion set, the present invention proposes an anticoagulant hemostatic infusion set with a hemostatic sealant floating plug capsule tube, which can make the hemostatic infusion set make the intravenous injection needle stop when the liquid is stopped. Within a few hours, a small amount of infusion can be infused into the vein, so it can not only avoid the above-mentioned blood coagulation at the intravenous injection needle due to the long time of stopping the liquid, but also prevent the infusion tube from getting air, In addition, if the nurse handles the infusion set in time, it can avoid the waste of infusion caused by the infusion of the residual infusion in the dripping funnel due to the short stop time.
