Description

Transfusion system convenient for flow regulation

Technical Field

The utility model belongs to the technical field of the medical supplies technique and specifically relates to a transfusion system convenient to adjust flow is related to.

Background

The infusion apparatus is a common medical consumable, and a channel between a vein and liquid medicine is established through aseptic treatment for intravenous infusion. Generally, the infusion set is formed by connecting eight parts, namely a vein needle or a needle, a needle head protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a Murphy dropper, a puncture outfit, an air filter and the like, and a part of the infusion set also comprises an injection piece, a medicine adding port and the like. At present, the flow rate of the infusion is adjusted by a roller to slide in an inclined cam groove, and the flow rate is adjusted by adjusting the compression degree of the roller on the infusion tube. The different degree of compaction makes the size of liquid latus rectum (passageway) change, and the big latus rectum that according to fluid dynamics principle fluid passed through is the resistance that produces less for the pipeline, and on the contrary, the small latus rectum is less, and the resistance just is big. The regulator can regulate the pipeline resistance, and the smaller the resistance, the faster the flow rate. Conversely, the greater the resistance, the slower the flow rate. The conventional flow rate regulator has the following disadvantages: (1) the nurse needs to adjust the flow rate according to experience during the transfusion operation, and the work of adjusting the flow rate is complicated. (2) The roller is easy to loosen or damage when in use, and the flow speed stability is influenced. (3) The patient regulates the flow privately and has risk.

Disclosure of Invention

During the infusion operation, the height of the suspension liquid can be set by referring to two marking lines, and the specific setting method comprises the following steps: the height difference between the needle head and the end position of the puncture outfit is kept within the range of 80-100 cm by adjusting the liquid suspension height, so that no obvious difference in liquid flow rate can be realized, and the stability and the standardization of the liquid flow rate are further ensured.

The utility model discloses the advantage as follows: 1. the operation is simple and convenient, the labor and the time are saved, and the selection of different flow rates can be realized by clamping different branch pipelines. 2. The reliability is good, and the problem that the roller of the traditional flow rate regulator is easy to loosen or damage to influence the stability of the flow rate is avoided. 3. Standardized operation is achieved without adjusting the flow rate by empirical estimation. 4. The marking line is arranged on the infusion tube, so that the stability and the standardization of the flow rate of the liquid are further ensured.
