[0001] The utility model relates to the technical field of medical devices, in particular to an infusion set for preventing gas embolism. Background Technique

[0002] Intravenous infusion is a common clinical treatment method. Different from forms such as oral administration, intravenous infusion is a method of injecting a large amount of sterile liquid, electrolyte, and drug into the body through a vein by using the principles of atmospheric pressure and hydrostatic pressure. During the process of intravenous infusion, an infusion set will be used. During the infusion process, if the liquid runs out and the normal saline medicine bottle or normal saline medicine bag is not replaced in time, it is easy for air to enter the human blood circulation system, thereby inducing gas embolism and causing discomfort to the patient. In severe cases, it will lead to life-threatening situations.

[0003] CN218889993U discloses an infusion set for preventing backflow and air entry during infusion.

Photosensors 52 are arranged at both ends of the clamping pads 55 fittingly installed on the U-shaped clamping blocks 54.

[0067] The specific usage method of the infusion set in this embodiment is as follows:

[0068] (1) First, the operator needs to connect the upper hanging bottle 4. Then, the Murphy's dropper 31 connected to the hanging bottle 4 connects the top pipe of the butyl rubber stopper 41. Moreover, the top of the hanging bottle 4 is buckled through the toggling buckle 66, and the piping of the infusion set is completed after buckling.

[0069] (2)Based on the penetration at one end of the hose 42: Install the liquid level alarm module 5 on the hose 42 to provide double insurance. When infusing, if the dripping stage of the infusion is completed, an alarm is first issued.

[0070] (3)Autonomous sealing: The Murphy's dropper 31 realizes the guiding and dripping of the liquid. At this moment, it is placed in a conical shape at one end of the Murphy's dropper 31. Once the liquid level is low during the placement stage, one end of the floating ball 322 naturally drops by using one end of the liquid guiding port 3211 at the bottom. During the dropping stage, the outer wall edge of the floating ball 322 seals with the outer wall of the conical hopper 321. Finally, after the sealing is completed, one end of the conical hopper 321 is closed. Controlled by the change of the internal and external air pressure difference, when one end of the floating ball 322 abuts and seals, it is ensured that the liquid below can be continuously guided and exported inside the accommodation cavity.

[0071] (4)The branch flexible hose 13 conveys the liquid: After guiding one end of the corresponding connecting head 12 and injecting it with one end of the injection needle 15, the liquid is conveyed to the patient. The purpose of this is to conveniently remind the medical staff to come and change the dressing in time. In addition, the combination of the alarm and the automatic sealing allows the medical staff to have enough time to prepare the medicine, avoiding putting the patient in an emergency situation and effectively preventing air embolism.
