Infusion general flow velocity regulator

Abstract

The invention discloses an infusion general flow velocity regulator. The regulator comprises a shell, a roller and an infusion conduit, wherein the shell comprises an inclined bottom wall and a pair of side walls; a pair of opposite sliding chutes is formed on the pair of side walls; the roller is provided with a roller shaft; the two ends of the roller shaft are arranged in the pair of sliding chutes respectively; and the infusion conduit passes through the shell and is positioned between the bottom wall of the shell and the roller. The regulator is characterized in that: the two ends of the roller shaft are provided with a gear respectively; racks are arranged on the side walls of the pair of sliding chutes; and the two gears are engaged with the racks in the pair of sliding chutes respectively. In the long-time infusion process, the gears are engaged with the racks in the sliding chutes, so that the roller cannot move without artificial factors, and the stability of infusion speeds is ensured.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a flow rate regulator for clinical infusion. Background technique [0002] Infusion is a commonly used treatment method in clinic. According to the needs of the patient's condition, various drugs, blood, nutrients, etc. are injected into the human body. The adjustment of the infusion rate is the primary task after successful venipuncture, the basic technical operation of nursing. The infusion speed should be adjusted according to the patient's age, condition, drug properties, and infusion purpose. According to the clinical nursing experience of the hospital for many years, the infusion adjustment speed is summarized as follows: [0003] 1. Adjusted according to the properties of the drug, certain drugs such as antibiotics and hemostatic drugs are routinely infused clinically, and the infusion rate is generally 60-80 drops per minute; [0004] 2. According to the condition and th...

Problems solved by technology

[0004] 2. According to the condition and the purpose of infusion, the infusion speed should be slow for patients with craniocerebral and cardiopulmonary diseases

During the infusion process of this roller-slope flow rate regulator, the rollers often slip, which causes non-human factors to change the infusion speed, and cannot guarantee the accuracy of infusion adjustment.

Simultaneously, above-mentioned defective also can force medical personnel to increase the frequency of infusion monitoring, has increased the workload of nursing personnel
