The present invention relates to a guider for separating a tube, and more particularly, to a guider for easily separating a tube and a catheter which are coupled to each other.
In a medical field, medical image is obtained by using CT, PET, or MRI to inspect functions of the brain or circulatory organs in human bodies. In this case, an external material such as a contrast agent is injected into a patient's body to increase a degree of image contrast.
To inject the contrast agent into the patient, a tube is connected to a catheter connected to a blood vessel, and the contrast agent is injected into the human body through the tube. A Y-type adapter (or connector) may be used as the catheter for injecting the contrast agent.
To take the medical imaging several times, a process of separating the tube from the catheter connected to the patient and connecting the tube to the catheter again is repeated. However, because the contrast agent has significantly high viscosity, there is a problem in that it is physically difficult to perform the process of separating the catheter and the tube.
In the related art, a user (e.g., a physician, a nurse, a radiographer, etc.) separates a tube and a catheter by applying grasping power to a connecting portion between the tube and the catheter with bare hands or the user separates the tube and the catheter by holding (or fixing), with medical forceps, the connecting portion between the catheter and the tube and then rotating the connecting portion.
To solve the above-mentioned problem, an object of the present invention is to provide a guider for separating a tube which may be used to enable a user to easily separate the catheter and the tube without great effort. That is, an object of the present invention is to provide a dedicated guider for separating a tube from a catheter.
An exemplary embodiment of the present invention may provide a guider for separating a tube.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
The guider for separating a tube according to the exemplary embodiment of the present invention may include: a cylindrical body portion 100 which includes a through space 110 which is opened at both ends thereof and formed to enable a tube 10 to penetrate therethrough; and a wing portion 200 which is connected to an outer surface of the body portion 100 and transmits rotational force to the body portion 100.
Referring to
However, when a contrast agent is injected into the catheter and the tube 10, a significantly large amount of energy is required to rotate and separate, by hand, the Y-type adapter 20 and the tube 10 because of high viscosity of the contrast agent.
According to the exemplary embodiment of the present invention, the guider for separating a tube is fitted with the tube 10 and fixed to a coupling portion 11 of the tube 10, and then the user rotates the wing portions 200 by hand, such that a portion of the tube 10, which is coupled to the Y-type adapter 20, is rotated together with the body portion 100, and as a result, the tube 10 and the Y-type adapter 20 may be easily separated. The coupling portion 11 of the tube 10 according to the exemplary embodiment of the present invention means a tip portion of the tube where the tube 10 and the Y-type adapter 20 are connected to each other.
That is, the wing portions 200 according to the exemplary embodiment of the present invention may increase torque applied to the coupling portion 11 of the tube 10, thereby facilitating the rotation of the coupling portion 11 of the tube 10. That is, the wing portions 200 according to the exemplary embodiment of the present invention may serve to reduce the amount of effort required to rotate the coupling portion 11 of the tube 10.
In addition, each of the wing portions 200 according to the exemplary embodiment of the present invention may be formed in a thin plate shape to increase a contact area with the user's hand. In other words, each of the wing portions 200 may be manufactured to have a predetermined area and a predetermined shape that allow the user to easily hold the wing portions 200. Therefore, the user may hold or rotate the guider for separating a tube by using the wing portions 200.
In other words, when the user rotates the coupling portion 11 of the tube 10 by using the guider for separating a tube according to the exemplary embodiment of the present invention, the effort, which is required to rotate the coupling portion 11 of the tube 10, may be reduced in comparison with the related art, and as a result, it is possible to more easily separate the tube 10 from the Y-type adapter 20 in comparison with the related art.
Therefore, each of the wing portions 200 according to the exemplary embodiment of the present invention may protrude from the outer surface of the body portion 100 so as to have a predetermined length and may be formed in a thin plate shape which is curved from the upper side to the lower side of the body portion 100, so that the user may hold and rotate the wing portions 200.
That is, each of the wing portions 200 according to the exemplary embodiment of the present invention may be shaped such that the user easily holds and rotates the wing portions 200 by hand. In addition, the number of wing portions 200 according to the exemplary embodiment of the present invention may be at least one.
In more detail, only one wing portion 200 may protrude from the body portion 100, or a pair of wing portions 200 may be formed straight, that is, at 180°. In addition, two or more wing portions 200 may be formed at a predetermined angle, for example, at an angle of 120°.
Referring to
The body portion 100 according to the exemplary embodiment of the present invention may further include a fixing groove 400 which is fastened to a protrusion 12 that protrudes from the coupling portion 11 of the tube 10. As illustrated in
Referring to
When separating and rotating the guider for separating a tube with respect to the tube 10 coupled to the Y-type adapter 20, the fixing groove 400 according to the exemplary embodiment of the present invention may prevent the guider for separating a tube from spinning with respect to the tube 10 and allow the guider for separating a tube to rotate together with the coupling portion 11 of the tube 10, such that the tube 10 may be separated from the Y-type adapter 20.
Holes 210 each having a predetermined size may be formed at parts of the wing portions 200 according to the exemplary embodiment of the present invention.
The hole 210 according to the exemplary embodiment of the present invention is held or fitted with a latch including a nail or a pin, and as a result, the guider for separating a tube may be stored at a specific location. That is, the hole 210 according to the exemplary embodiment of the present invention may provide a loss prevention function so that the user does not lose the guider for separating a tube.
The guider for separating a tube according to the exemplary embodiment of the present invention may be manufactured by using at least one of metal and synthetic resin. In other words, the guider for separating a tube according to the exemplary embodiment of the present invention may be manufactured by using a material such as plastic having high strength in addition to iron.
