Abstract
The invention discloses an angiographic multi-cavity diameter-variable hydrophilic catheter which is a multi-cavity medical catheter having more than two cavities. The multiple cavities of the catheter can simultaneously expand or contract in a suddenly-changed or gradually-changed extrusion mode. The angiographic multi-cavity diameter-variable hydrophilic catheter disclosed by the invention is convenient to operate, and has the advantages of high service efficiency, high safety and reliability and cost saving.
Description
Technical field
The present invention relates to a kind of conduit, be specifically related to a kind of development multi-cavity reducing hydrophilic catheter.
Background technology
At present, along with the raising of therapeutic treatment level and the segmentation of catheter purposes.The effect of catheter in the diagnosis and treatment operation is more and more important.Varying in size owing to body cavities in some traditional operation.Need have development at a body, reducing, multi-cavity, hydrophilic functional character hardly may.The doctor can be in use, and the repeatedly different conduit of plug perhaps uses stainless steel tube to wait and reaches the successful purpose of operation repeatedly.Cause very big misery to patient.
Summary of the invention
Goal of the invention: the objective of the invention is for customer service deficiency of the prior art, a kind of simple in structure, esy to use, safe and reliable, development multi-cavity reducing hydrophilic catheter that product cost is low is provided.
Technical scheme: for achieving the above object, the invention provides a kind of development multi-cavity reducing hydrophilic catheter, have the above multi-cavity medical conduit in two chambeies, the multi-cavity cavity of described conduit enlarges simultaneously according to the pattern of extruding of sudden change or gradual change or dwindles.
Described reducer pipe is made in the raw material and is contained materials such as barium, bismuth, tungsten.Materials such as the barium that adding can be developed under X-ray in the raw material that material is selected and the human-body biological compatibility is best, bismuth, tungsten, raw material can raise and the softness of change along with body temperature.
Described development reducing catheter tube scribbles hydrophilic coating.Smeared the hydrophilic coating of 0.5 μ m-1.0 μ m on body, it is smooth and easy to make that body becomes when entering human body.
Described conduit is plastic catheter, rubber catheter or the conduit made by plastics and rubber mix.Body is provided with the measurement scale, makes things convenient for the doctor to locate in use.
Beneficial effect: development multi-cavity reducing hydrophilic catheter of the present invention, easy to operate, the service efficiency height, safe and reliable and saving cost, the multi-cavity reducing has been saved the program of many conduits of plug repeatedly, the potential medical hidden danger of having avoided plug process repeatedly to bring; The hydrophilic coating of body makes things convenient for conduit to insert human body, reduces patient's misery, has avoided the destruction of the relevant people soma that causes greatly because of resistance; During use, body is scale and development effect clearly, is easy to enter the human lesion position under the X-ray irradiation.
