Embodiment Construction

[0015] Next, a first embodiment of the present invention will be described with reference to FIGS. 1-4.

[0016] The indwelling catheter device 1 is similar to conventional indwelling catheter devices and has a catheter 3 . The catheter 3 is shaped like a tube and has a larger diameter proximal end portion 3A, a smaller diameter end portion 3B, and an intermediate tapered portion connecting the proximal end portion 3A and the end portion 3B. The end portion 3B is made relatively long, and has many through holes perpendicular to the axial direction of the conduit 3 at its end. The conduit 3 is inserted into the fitting hole 7A of the cover 7 having a pair of cover wings 5, and its proximal end portion 3A is tightly fixed to the cover 7 with its end portion 3B protruding from the fitting hole 7A.

[0017] The cover 7 has a connection portion 7B which is formed in a tubular shape and which is used to connect with the proximal end portion 3A of the catheter 3 . The connecting po...

Abstract

An indwelling catheter set is provided with a catheter, a cover connected with a proximal end of the catheter and a connector having a hemostatic valve housed therein. The connector is fixed to the cover. A hollow needle for transfusion to a patient is slidably fitted to an inside of the catheter.

Description

technical field [0001] The present invention relates to an indwelling catheter device for transfusion, which is used for treatment processes such as dialysis, infusion, blood transfusion, etc., especially relates to an indwelling catheter device that can effectively prevent blood from flowing out during each stage of infusion, for example, the device is placed on the patient's body The other end is connected with the infusion tube, and this device can ensure the safety after the needle is pulled out from the patient's body. Background technique [0002] A prior art of an indwelling catheter device has been disclosed in Japanese Patent Application Laid-Open No. 3-70502. This indwelling device has a hemostat that can be attached and detached from the catheter. The hemostat has a plurality of separable gaskets, each of which has a cylindrical bottom surface. When the needle of the catheter is pulled out, the many seals prevent blood from flowing out. [0003] When the cathet...
