A power transfusion device used in the portable intravenous injection system

Abstract

The invention relates to a fluid supply power device used in portable intravenous injection transfusion system. It belongs to medical equipment fields comprising drives, peristaltic pump, actuating mechanism and fluid hoses, and is characterized in that the peristaltic pump is planetary rotor pump, actuating mechanism and peristaltic pump are installed side-by-side in a portable flip-shell consisting of lower case, upper cover and rotational axis, connected by drives , transfusion curved pipe jacket and jacket pressure regulation mechanism cell are set at the outside of peristaltic pump roller, part of transfusion hose, is fixed outside of roller by curved pipe jacket, a flip-top control unit is installed on the upper cover of portable flip-shell, set the parameter input unit on inner surface of upper cover and a screen on external surface, set power under lower cover shell of portable flip-shell, connect the power and drive and control together. The whole device has a small size, light weight, nice portable and mobile performances and can achieve intelligent controlled transfusion. It can be widely used in transfusion therapy.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a device for inputting a liquid medium into a human body. Background technique [0002] Intravenous infusion is the most commonly used clinical rescue and treatment method, and it is also a commonly used drug delivery treatment technique in nursing profession. [0003] Clinically, depending on the drug and the condition of the patient, an appropriate infusion rate is often required. [0004] If the infusion is too fast, it may lead to poisoning, and in severe cases, it may cause edema and heart failure; if the infusion is too slow, the dosage may be insufficient or the infusion time may be unnecessarily prolonged, which will affect the treatment and increase unnecessary burden on patients and nursing work . [0005] The current routine clinical infusion generally adopts the gravity infusion method (commonly known as "hanging bottle"), and observes with eyes, and relies on manual ...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned technical solution adopts the mechanical pressure injection infusion method, which solves the shortcomings of the existing gravity infusion method, but because it uses a linear peristaltic pump (Linear Peristaltic Pump) as a pressure source, the entire device is relatively large in size, heavy and movable Poor performance, unable to meet the needs of use in a mobile state (such as stretcher transportation), limiting the freedom of movement of the patient during infusion / treatment
