Embodiment Construction

[0033] The making and using of the embodiments are discussed in detail below. It should be understood that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention. The expression of the structural position of each component such as up, down, top, bottom, etc. in the description is not absolute, but relative. These directional expressions are appropriate when the various components are arranged as shown in the drawings, but when the positions of the various components in the drawings are changed, these directional expressions are also changed accordingly.

[0034] The volume of the cavity in the existing connector is larger than that of the pipeline in the front section, resulting in a rapid decrease in the flow rate of the flushing fluid after entering the cavity of the connector, and it is difficult to rinse off the residual blood in some corners. Therefore, the embodiment of the p...

Abstract

The invention provides a connector comprising a housing having a first port, a second port and a first cavity communicating with the first port and the second port, a cover body connected with the housing and provided with a second cavity communicating with the first cavity, and a bulging part arranged in the first cavity and protruding and extending towards the second cavity; and the first cavity is provided with a side edge groove extending towards the second cavity in an inclined and bent mode. The groove structure of the connector can guide part of fluid flowing into the first cavity from the first port to the second cavity to form spiral upward vortex, so that the flushing area is enlarged, the flushing efficiency is improved, and the pollution risk is reduced.

Description

technical field [0001] The present invention relates to a connector, such as a connector suitable for connecting a plurality of conduits to each other in a liquid transport pipeline. Background technique [0002] In some cases of infusion, blood transfusion or blood collection operations on patients, in order to achieve therapeutic effects, it is necessary to connect multiple catheters to form an infusion line from the liquid medicine (or blood) to the patient. Among the multiple infusion lines are connected through connectors. [0003] For example, in order to collect blood samples from patients in the process of blood pressure monitoring, a connector is usually added to the monitoring pipeline, and the blood collection operation is carried out after connecting the connector with a syringe. Condensation in the circuit requires flushing of the circuit (including connectors) to remove blood. A typical way is to flush the flushing liquid in the flushing bag on the upstream s...
