Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the high-speed precision intelligent safety infusion set with automatic exhaust, automatic liquid stop and anti-blood return includes a drip funnel 1, a downcomer 9 arranged at the bottom of the drip funnel, a positive pressure needleless connector special interface 10 and an infusion needle 11 arranged at the end of the downcomer 9 . The dripping funnel 1 is provided with a drug filter membrane 6 through which all the liquid medicine passes. The drug filter film 6 is a hydrophilic filter membrane with countless fine inner holes, which can effectively filter out insoluble particles of more than 5um and more than 95% of the drug liquid. The insoluble particles below 5um, and the patency is good and not easy to block. Under the action of a static pressure head of 1 meter, it can infuse more than 1200ml of normal saline in 10 minutes, wh...

Abstract

The invention relates to an automatic exhaust and liquid stop and anti-blood backflow high-speed precision intelligent security infusion set, and belongs to the technical field of medical appliances. The infusion set comprises a drip chamber, a lower catheter arranged at the bottom of the drip chamber, a special interface for a positive pressure needle-free connector arranged at the tail end of the lower catheter, and an infusion needle, wherein a drug passing membrane through which all liquid drugs pass is arranged in the drip chamber, and comprises a drug passing membrane fixing belt fixed by the drip chamber, and a drug passing membrane free belt unfixed by the drip chamber, and a partition plate is arranged above the drug passing membrane; and a cavity above the drug passing membrane in the drip chamber is divided into a liquid inlet outer cavity and a liquid inlet inner cavity by the partition plate, and the liquid inlet outer cavity is communicated with the drug passing membrane fixing belt through a channel arranged on the drug passing membrane fixing belt. The infusion set has the advantages of automatic exhaust, automatic liquid stop and blood backflow prevention, high-speed precision filtration, the special interface for the positive pressure needle-free connector, automatic liquid storage and the like, thus realizing the safe and intelligent infusion.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a high-speed precision intelligent safety infusion set with automatic exhaust, automatic liquid stop and anti-blood return. Background technique [0002] At present, most of the infusion sets used in medical institutions are traditional infusion sets. Traditional infusion sets have the following disadvantages: 1. Manual exhaust is required for medical staff, which is time-consuming and labor-intensive and has residual air bubbles; 2. Failure to change the bottle in time may lead to blood return or gas input 3. The insoluble particles in the liquid are injected into the human body, and long-term accumulation forms embolism, which endangers the human body; 4. The flow rate is slow, which is not suitable for first aid; 5. The interface at the end of the catheter is not firm and cannot be stably combined with the positive pressure needleless connector (positive Th...
