Abstract
According to the present invention, there is provided a device for inserting a urethral catheter having a fluid passage and a through-hole communicating with the fluid passage and smaller than the fluid passage at the distal end, the fluid passage having a diameter smaller than the diameter of the fluid passage, There is provided a guiding catheter for inserting a urethral catheter having a body portion extending longer than a urethral catheter and an extension extending from a distal end of the body portion and having an outer diameter smaller than the diameter of the through-hole.
Description
The present invention relates to a technique for inserting a urethral catheter into a urethra, and more particularly, to a guide mechanism and a urethral catheter kit having the guide mechanism used to allow a urethral catheter to pass through a narrow stenosis site.
Urethral catheters are inserted through the urethra to drain urine from the patient's bladder. Because the urethral catheter is made of a flexible and soft material, when the portion of the urethra is narrowed by stenosis or the like during insertion through the urethra, the distal end portion may not be bent and can not enter. The inventor of the present application has developed a method of inserting the
It is an object of the present invention to provide a guider mechanism and a urethral catheter kit having the guider mechanism used for insertion of the urethral catheter.
Another object of the present invention is to provide a guider mechanism and a urethral catheter kit having the guider catheter that are used to allow the urethral catheter to easily pass through the narrowed region in the urethra.
According to an aspect of the present invention,
A device for inserting a urethral catheter having a fluid passageway and a through-hole communicating with the fluid passageway and smaller than the fluid passageway at its tip, the device having an outer diameter smaller than the diameter of the fluid passageway and greater than the through- And an extension portion extending from a distal end of the body portion and having an outer diameter equal to or smaller than a diameter of the through-hole.
The body may have a linear portion extending in a straight line and a curved portion bent in one direction from a tip of the straight portion, and the extension portion may be connected to the tip of the curved portion.
The guider mechanism may further include a handle formed on the body, and the handle may be positioned to be exposed to the outside of the urethral catheter when the distal end of the body is inserted into the urethral catheter.
According to another aspect of the present invention,
A urethral catheter having a fluid passageway, said urethral catheter communicating with said fluid passageway and provided at its distal end with a penetration smaller than said fluid passageway; And a guider mechanism having a body portion that is smaller than the diameter of the fluid passage and has an outer diameter larger than the through-hole and that is longer than the urethral catheter, and an extension portion extending from a distal end of the body portion and having an outer diameter smaller than the diameter of the through- Lt; / RTI > catheter kit is provided.
According to another aspect of the present invention,
A device for inserting a urethral catheter having a fluid passage and a through-hole communicating with the fluid passage and smaller than the fluid passage, the guide wire having an outer diameter smaller than the diameter of the through-hole; And a guider tube extending in the longitudinal direction and having guide passages open at both ends thereof, wherein a diameter of the guide passage is larger than an outer diameter of the guide wire, and an outer diameter of the guider tube is smaller than a diameter of the fluid passage Wherein the catheter is inserted into the catheter.
The guider tube may have a linear portion extending straight and a curved portion bent in one direction from a tip of the straight portion.
The guider tube may have a handle portion positioned to be exposed to the outside of the urethral catheter when the distal end of the guider tube is inserted into the urethral catheter.
According to another aspect of the present invention,
A urethral catheter having a fluid passageway, said urethral catheter communicating with said fluid passageway and provided at its distal end with a penetration smaller than said fluid passageway; And a guider tube having a guider wire and a guider tube extending in the longitudinal direction and having both ends opened, wherein the guider wire has an outer diameter of not more than a diameter of the through-hole, Is larger than the outer diameter of the guide wire, and the outer diameter of the guider tube is smaller than the diameter of the fluid passage.
According to the present invention, all of the objects of the present invention described above can be achieved. Specifically, the catheter is inserted into the urethral catheter so as to support the urethral catheter by inserting the body or the guider tube into the urethral catheter because the catheter is inserted into the urethral catheter. This allows the urethral catheter to easily pass through the site of stenosis.
