Description

Technical Field

[0001] The utility model relates to the technical field of medical tools, in particular to a medical dropper. Background Art

[0002] In the medical field, droppers are a common tool for measuring and transferring liquids and are widely used in various medical operations. Traditional medical droppers are usually made of glass or plastic. Although these materials have certain durability and chemical stability, they may break, deform or chemically corrode in certain specific application scenarios, such as when high-temperature disinfection is required or when they are in contact with certain chemicals for a long time, thus affecting the use effect and safety of the droppers. At the same time, droppers made of these materials need to be produced in a high-temperature environment, which results in high cost.

[0003] In addition, traditional medical droppers are usually simple in terms of flow rate control, often relying only on the diameter of the dropper body and the gravity of the liquid itself to control the flow rate, and lack a more precise flow rate adjustment mechanism. This, to a certain extent, limits the application of droppers in medical operations that require precise control of liquid flow rate.

[0004] In terms of structural design, traditional medical droppers also have some shortcomings. For example, the connection between the liquid-absorbing rubber tip and the dropper body may not be stable enough, and it is easy to loosen or fall off; at the same time, the grip of the dropper body may not be comfortable enough, and long-term use may easily cause hand fatigue.

[0005] Therefore, it is necessary to design a medical dropper to solve the above problems. Utility Model Content
