Description

A Portable Automatic Squeezing Infusion Set

technical field

The utility model relates to the field of medical equipment, in particular to a portable automatic squeeze infusion set.

Background technique

The survey shows that clinically about 90% of hospitalized patients still use the infusion device invented by "Murphy's" more than 110 years ago for infusion therapy, which completely relies on the difference in atmospheric pressure at different heights for infusion. It is inconvenient for patients to perform other activities during infusion. This infusion set has the deficiencies in the following aspects: (1) there must be a height difference in body position, the position of the liquid is raised to form a liquid level difference between the liquid medicine and the infusion person, and the liquid medicine is imported into the vein by the effect of gravity, i.e. infusion The bottle must be hung above the patient; (2) when the medical personnel do not operate properly, the infusion pipeline expands and enters the air. The workload of medical staff increases the psychological burden of patients and their families; (3) the existing common infusion set adopts a pulley type without fixed gears, which can only be obtained from the dripping speed in Murphy's dropper and the experience value of medical staff. To control, can not accurately control the infusion speed and specific infusion flow, prone to infusion speed is too fast or too slow to cause adverse reactions or fail to achieve curative effect.

Beneficial effects: the portable automatic squeeze infusion device breaks the traditional way of gravity infusion, and gets rid of the limitations of being accompanied by someone and holding the infusion bottle high when the infusion moves around, no matter whether the patient is lying, walking, lying, static or dynamic , will not affect the infusion, alleviate the patient's physical discomfort caused by long-term lying or sitting quietly, and avoid the existing problems caused by ordinary infusion sets. For example, in the case of insufficient or no infusion stand for battlefield rescue and disaster relief, the portable automatic squeeze infusion set can overcome adverse environmental factors such as severe bumps and swings on the way, and its operation is simple and convenient, and the infusion quality is reliable, which can greatly improve Reduce the workload of medical staff. The portable automatic squeeze infusion set is easy to carry and safe to use. The flow controller is combined with the application of gear position control and fuzzy control to precisely control the infusion flow rate of the medicinal liquid and improve the safety and comfort of intravenous infusion. The low-cost design concept of the portable infusion set is more conducive to its large-scale promotion in clinical care, which not only brings convenience to more patients, but also further improves the level of care and work efficiency.
