Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an intravenous infusion anti-leakage device. Background Art

[0002] Intravenous infusion utilizes atmospheric pressure and hydrostatic pressure to deliver large quantities of sterile fluids, electrolytes, and medications through the veins. The injection of large quantities of fluids, electrolytes, or blood into the veins is called intravenous infusion. Depending on the injection site and the type of infusion, it can be categorized as peripheral intravenous infusion, central intravenous infusion, high-nutrient infusion, and blood transfusion. To prevent leakage of the delivered fluid during intravenous infusion, an intravenous infusion anti-leakage device is currently required.

[0003] An intravenous infusion anti-leakage device disclosed in publication number CN209154741U has a simple structure and good safety. When the infusion is normal, the liquid enters the infusion needle through the opening formed by the valve of the one-way valve structure. When liquid leakage occurs, the subcutaneous tissue causes the pressure on one side of the infusion needle to increase due to liquid accumulation. When the pressure on one side of the infusion needle is greater than the pressure of the liquid in the pipeline, the free edge of the one-way valve structure is closed, the infusion channel is closed, and the leakage is blocked in time to prevent the liquid from entering the subcutaneous tissue, causing subcutaneous tissue necrosis or more serious accidents. At the same time, an alarm is used in conjunction with the use of an alarm. Due to the closure of the one-way valve structure, when no liquid drips into the dropper of the infusion device, the alarm sounds, prompting the nursing staff to deal with it in time. However, if the nursing staff is short of manpower, no accident will be caused by leakage. The device is easy to use and can reflect and solve leakage problems in a timely, effective and rapid manner. The device is suitable for industrial production and market promotion and application.

[0004] However, the intravenous infusion anti-leakage device has the following disadvantages:

[0005] (1) The intravenous infusion anti-leakage device has a weak fixing function. Due to the different conditions of each patient during use, the patient may move around, which may cause the infusion device to leak;

[0006] (2) The intravenous infusion anti-leakage device has a weak adjustment function. When used, due to the different body shapes of patients, the fixation effect may not be effective, which may cause discomfort to the patient. Utility Model Content
