Abstract

The invention discloses a sterile catheter sheath comprising a socket, a tube and a cover. The tube is inserted into the socket, the socket comprises a front end and a rear end, and a seal gasket is mounted in the socket, and is pressed and fixed to the end opening of the socket through the cover. The sterile catheter sheath is characterized by further comprising a sleeve and a circular steel cap, the circular steel cap has a flared opening, the tube is sleeved on the circular steel cap, and the front end and the rear end of the socket are molded integrally. The sterile catheter sheath overcomes the defect of cost increase due to the design of dividing the socket into the front part and the rear part in the prior art.

Description

technical field [0001] The invention relates to a medical device, in particular to a sterile catheter sheath for assisting interventional therapy. Background technique [0002] As an auxiliary guiding device for arteriovenous interventional surgery, the introducer sheath plays an important role in interventional therapy. In particular, the disposable sterile catheter sheath is an in vitro auxiliary consumable for cardiovascular interventional diagnosis and treatment. During PTCA angioplasty, the catheter sheath is left in the arterial vessel to establish a connection channel between the blood vessel and the outside world, so that it can be used for cardiovascular interventional angiography. , Cardiovascular dilation or placement of stents. The catheter sheath usually mainly includes a sheath tube seat and a sheath tube inserted into the sheath tube seat, wherein there is a large difference in the wall thickness of the front and rear parts of the sheath tube seat (the wall t...
