Embodiment Construction

[0018] Referring to the drawings in detail, and in particular, a general method of use for forming a blood seal of FIGS. 1a-1d, FIG. Constructed of strong molded plastic material, it is mounted on the front end 12 of the cover 14 . The steel sleeve 16 can be drawn back into the cover 14 through the head end 10 as the former is withdrawn from the patient's body, so as to protect clinical personnel or physicians from needle sticks. The rear port 18 of the sleeve 16 extending into the cover 14 is fixedly connected to the port 20 of the blood chamber 22 so that it can communicate with the interior space 24, and this rear port 18 is also adapted to extend around the sleeve 16. adhesive, so that as described below, the cannula 16 is permanently fastened to the blood chamber 22.

[0019] The head end 10, which is fixedly mounted on the end or front end 12 of the housing 14 and is formed of molded plastic material, generally has a cylindrical outer profile 28, such profile 28 having a ...

Abstract

An intravenous catheter insertion devices, and in particular an extruded plastic blood sealing gasket for a blood chamber of the safety catheter. A cannula extends through the blood gasket with the assurance of a seal being present therebetween during relative sliding movement between the cannula and the blood gasket. Moreover, disclosed is a method of forming a blown-in-place extruded plastic gasket for a safety catheter adapted to slidingly receiving a cannula in sealing engagement therewith in a simple and inexpensively produced manner.

Description

technical field [0001] The present invention relates generally to an insertion device for an intravenous catheter, and is particularly applicable to a blood seal for a blood lumen of a safety catheter. Under the condition that the cannula and the blood sealing pad can be relatively slidable and sealed, the sleeve tube extends out through the blood sealing pad. The present invention introduces a new method of forming blown-in-situ gaskets for safety conduits which accept sleeves smoothly in a sealed connection and which are simple and inexpensive to produce. Background technique [0002] According to the special characteristics of the present invention, various safety catheter structures must prepare a blood sealing gasket, for example, in the shape of a hollow steel needle, which can pass through smoothly under the condition of sealed connection. Typically, a component of an IV catheterization device, such as a tip or shield mounted on a cap containing a blood lumen, has a ...
