Description

A four-link automatic liquid changing and flushing device

Technical Field

The invention relates to the technical field of infusion equipment, and in particular to a four-connection automatic liquid-changing and tube-flushing device.

Background technique

Infusion is the most common nursing operation in hospitals. The main problem now is that most patients in hospitals have many types of infusions, such as the infusion set disclosed in the disposable infusion set (patent number: CN204092706U). There are many specifications for each infusion volume, especially for surgical patients, who need about 5 to 10 bottles of 100ml liquid. In addition, there are 250ml, 500ml and three-liter bags. The infusion time of these liquids is short and the replacement is frequent. When collective infusion is performed, many replacements are not timely, which brings many disputes and takes up most of the nurses' time. It can be said that nurses' time is almost all changed by changing the dressings. Secondly, constantly changing the liquid increases the risk of infusion reaction.

In order to solve the shortcomings currently existing in the market, it is urgent to improve the technology of infusion devices.
