Description

A self-exhausting liquid-stopping infusion set

technical field

The product of the utility model belongs to the field of medical devices, in particular to an infusion device with automatic exhaust and liquid stop functions during the process of infusion of medicinal liquid for patients. the

Background technique

Now clinical use of ordinary infusion set before infusion of medicinal liquid, need to invert the dripping funnel, and squeeze the dripping funnel, so that a certain amount of liquid is filled with the dripping funnel, then put the dripping funnel in order to get rid of most of the air bubbles, if the operation Improperly, the liquid and gas mixture in the drip funnel enters the hose, forming air bubbles. If air bubbles enter the patient's body, it is easy to cause air embolism hazards. Therefore, before the infusion, the medical staff must remove the air bubbles in the infusion set hose as much as possible. This manual air bubble removal process is cumbersome and time-consuming, which increases the workload of the medical staff. Moreover, in the process of infusion of the medical solution by the patient, if the infusion needle is not pulled out after the medical solution is transfused, adverse consequences of blood backflow will occur. the

Contents of the invention

The purpose of this utility model is to provide an automatic exhaust and stop liquid infusion set, which can automatically exhaust the liquid during the infusion process, so that the liquid can be stopped after the liquid medicine is transfused, and blood backflow can be prevented. the

The utility model is realized by adopting the following technical solutions: an automatic exhaust and liquid-stopping infusion device, including a bottle stopper puncturer assembly, an air intake pipe, an air filter, a flow regulator, a three-way connecting pipe, a dropper, and a dropper Components, long tubes, hard joints, latex tubes, liquid medicine filters, and intravenous infusion needles are characterized in that: an automatic exhaust device (15) is inserted above the infusion set dripping funnel (7), and an automatic exhaust device (15) ) is equipped with an exhaust plug (16), an air filter membrane (19) and an exhaust pipeline (17), while the lower end of the automatic exhaust device (15) is close to the inner wall of the dripping funnel (7) and is located in the dripping funnel ( 7), the lower end of the exhaust pipe (17) is not on the same surface as the liquid outlet at the upper end of the dripping funnel (7), and the lower end of the dripping tube (6) is connected to the upper end of the dripping funnel assembly (7) by bonding. The upper end of the dropper (6) is connected with the three-way connecting pipe (5) or directly with the lower end of the cork piercer assembly (1) to form a liquid inlet passage. the

An automatic liquid-stopping device (8) composed of an upper shell (20), a lower shell (21) and a liquid-stopping film (22) is installed at the lower end of the dripping funnel (7) of the infusion set. The liquid inlet hole of the upper shell (20) is connected to the drip funnel (7), the liquid outlet hole of the lower shell (21) is connected to the long pipe (10), and there is a liquid stop film (22) in the middle for filtering, and the liquid stop film (22) It can be a precision filter membrane, which is used to filter insoluble particles in the liquid medicine during the infusion process. the

The utility model adds an automatic exhaust device with an exhaust function and an automatic liquid stop device with a liquid stop function on the basis of a common disposable infusion set. In the clinical infusion process, the utility model has the same steps as common infusion sets, and reduces the method of manually removing air bubbles by squeezing the drip funnel, and prevents adverse consequences of blood backflow or air embolism. Greatly reduce the workload of medical staff. the

The utility model has the advantages of simple structure, simple manufacturing process and low production cost. In particular, the automatic exhaust and stop liquid infusion set can automatically exhaust during the infusion process, which can stop the liquid after infusion of the medicine, automatically close the infusion channel to prevent blood backflow, easy to use, and make the whole process of infusion safer for patients. .
