Abstract
A catheter with liquid flow control means having a hub portion and a bore therethrough, where the hub portion is resiliently distortable to close the bore by manual pressure prior to connection of the hub portion to other apparatus, but closure of the bore by manual pressure is prevented after the connection has been made.
Claims1
In a catheter assembly comprising a flexible catheter tube having an axial bore, a unitary hollow body having a distal end and a proximal end, said catheter tube being inserted into the distal end of said hollow body and in fluid communication with the hollow of the body, the proximal end of said hollow body forming a female infusion fitting, and a male infusion fitting inserted into said female infusion fitting;
- the improvement which resides in that the hollow body of the catheter assembly consists of a non-collapsible portion extending rearwardly from the distal end and a collapsible portion with memory immediately adjacent to said non-collapsible portion extending to the proximal end, and has a rigid male infusion fitting of the same length as the collapsible portion removably inserted into the collapsible portion, whereby said hollow body becomes non-collapsible over its entire length.
