Description

A new type of infusion device that can remove air bubbles

technical field

The utility model belongs to the technical field of novel infusion sets, in particular to a novel air permeable infusion set capable of removing air bubbles.

Background technique

Disposable infusion set is a common medical consumable. After aseptic processing, a channel is established between the vein and the liquid medicine for intravenous infusion. Generally, it is composed of eight parts connected by intravenous needle or injection needle, needle protective cap, infusion hose, liquid medicine filter, flow rate regulator, drip pot, cork puncture device, and air filter, and some infusion sets also have injection parts. , dosing port, etc.

Working principle: Under the action of atmospheric pressure, the liquid in the bottle flows into the drip bucket along the thinner infusion hose. When the pressure of the drip bucket water column is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose.

Before use, medical staff check the disinfection validity period of the disposable infusion set and whether there is any air leakage or other abnormalities in the packaging, take out the infusion set, and insert the bottle insertion needle part into the infusion bottle (if it is an infusion bag, unless the air inlet tube and the bottle insertion needle are integrated. Infusion set, otherwise it is not necessary to open the air inlet device, that is, insert the air inlet needle or open the air inlet hole), hang the infusion bottle on the infusion rod, exhaust the air until the liquid flows to the lower end of the infusion tube, close the regulator, and then insert the intravenous needle Puncture the sterilized vein, and after fixing it, untie the tourniquet and adjust the flow rate.

Intravenous infusion is a nursing activity with the most clinical application. In clinical practice, when patients are treated with infusion, air bubbles are often generated in the infusion tube. There are many reasons for bubbles, such as: ambient temperature difference, drug characteristics, pipeline defects, and improper operation. If air bubbles enter the patient's venous blood vessels through the infusion tube, it can cause air embolism and be life-threatening, so it is strictly forbidden for air to enter the vein from the intravenous infusion route.

With the extensive use of infusion tubes and other products in clinical practice, the problem of air bubbles cannot be ignored and has always been the focus of doctors and patients. Clinically, there are three methods of exhausting we usually use: the upper-bounce method, the lower-row method and the acupressure method. The loading method is mainly used to enter a small amount of gas into the infusion set. For a large amount of gas entering in this case, the loading method is very laborious and time consuming. The down-flow method usually results in waste of liquid medicine, and it is not suitable to use this method when the more expensive liquid medicine is input. The acupressure method is to close the regulator, gently squeeze the Murphy dropper with your hands, so that the liquid in the Murphy dropper reaches 1/2 to 2/3, place the index finger of the left hand under the air section, and wrap the infusion tube tightly around On the left index finger, twist upwards in sequence until the air bubble is pressed into the Murphy dropper. In clinical practice, once air bubbles are found in the infusion tube, the infusion is stopped immediately, and the infusion is continued after the air bubbles are removed. This will adversely affect the treatment of patients, increase the psychological burden of patients, and increase the workload of medical staff.

The intelligent infusion pump commonly used in clinical can detect air bubbles. Once air bubbles pass through the intelligent infusion pump, the intelligent infusion pump will alarm and automatically stop the infusion. After the medical staff have finished processing the air bubbles, the infusion will continue. The detection of the intelligent infusion pump can effectively prevent air from entering the vein, but it is powerless to remove air bubbles, and the inconvenience caused by air bubbles in the infusion tube still exists.

Therefore, it is urgent to solve the problem of removing air bubbles under the premise of uninterrupted infusion process.
