AI Technical Summary
Technical Problem
Existing medical fluid connectors use razors to cut the seals during manufacturing, leading to inconsistencies and easy tearing, which affects the sealing effect.
Method used
The seals of the pinless fluid connector are manufactured using molding, compression, and lubrication techniques. Tension is reduced through guide grooves and lubrication grooves, avoiding the use of razor cutting, and forming an insertion area to allow the center post to penetrate and provide a fluid path.
Benefits of technology
It improves the sealing and consistency of the connector, reduces the risk of tearing, and ensures the stability and flow of fluid paths.

Abstract
Seals for needleless fluid connectors are disclosed. A seal for a medical fluid connector can include a first portion and a second portion compressed together to form the seal. Inner surfaces of the first portion and the second portion include grooves. When the first portion and the second portion are compressed together, fluid cannot pass between the two portions. In other words, fluid cannot pass through the seal. The seal can be penetrated by a center post at an insertion region compressed by the grooves. When the center post penetrates the seal, the center post provides a fluid path through the seal. The grooves also include a lubricant that limits the amount of friction between the seal and the center post.
