Description

{DEVICE FOR SUPPORTING FOLEY CATHETER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urethral catheter fixation device, and more particularly, to a urethral catheter fixation device which is supported by a penis and is inserted into a urethra so as to fix a urethral catheter for releasing urine inside the bladder.

Generally, a catheter is a device for injecting a catheter into a body cavity, a urethra, or a blood vessel so as to make access to a surgical tool, or to inject a body fluid into the outside or inject a drug into a surgical site.

The urethral catheter, which is an element of the catheter, is used to inject the drug into the bladder by inserting the tube into the inside of the bladder along the urethra, or to discharge the urine in the bladder to the outside in order to relieve extreme urine stagnation due to enlargement of the prostate.

However, because these urethral catheters are installed in the urethra, they may cause pain due to the friction between the urethral catheter tube and the urethra inner wall, or may cause inflammation due to the urethral injury. When the urethral catheter tube moves, the symptoms become more severe. In addition, when a long-term urethral catheter is to be maintained, side effects such as urinary tract infection and stenosis of the urethra may occur. In order to overcome the disadvantages of the urethral catheter, general hospitals disinfect the urethral end of the catheter and the urethral catheter After wrapping with a bandage, fixed with a bandage (dressing), a portion of the catheter outlet was fixed to the body with a bandage. However, in the above method, it is necessary to perform a process of removing the bandage and the gauze when dressing. In this process, the flow of the catheter tube may occur, causing the urethral pain or the urethral injury, and it takes a long time.

Korean Registered Patent No. 10-0982017 (Registered on Sep. 7, 2010, hereinafter referred to as 'Prior Art Document 1') proposed a catheter fixing device. The prior art document 1 includes a cradle having an injection port through which a catheter inserted in the urethra passes, and which is installed to enclose the penis; A catheter fixing unit installed at the injection port and fixing the catheter; A balloon member disposed at a rear end of the cradle; And a cradle fixing member for fixing the cradle to a human body. The above-mentioned prior art document 1 has a disadvantage in that it is inconvenient to move a patient because the bulb is covered with a dome around the genital area, and the fixing member fixing the body to the human body also provides a discomfort when worn.

A catheter with a protective cover of the Chinese Utility Model Registration 2052687995U (registration dated June 06, 2016; hereinafter referred to as 'Prior Art 2') was presented. In the catheter including the tubular body, the tubular body is coupled with a protective cover that covers the penis on the outer wall, and the protective cover is coaxial with the tubular body in the form of a tube whose upper end is closed and the lower end is opened And the lower end is attached to the outer wall of the penis by the medical tape. In the prior art document 2, since the material is made of an elastic material such as latex, it is directly mounted on the penis, and therefore, it can be used without a separate fixing member. However, the prior art document 2 has a small size because the hole through which the tubular body is inserted into the protective cover is in close contact with the tubular body. Therefore, when the catheter is applied to an existing catheter having one to three connecting means having a diameter larger than that of the tubular body such as a urine storage container or a distilled water injector of a balloon in an inlet portion, it's difficult. In addition, since a large stimulus is delivered to the catheter in the process of separating, it causes pain to the patient. Therefore, it is difficult to apply the catheter to the existing urethra catheter, and since it is closed by the elastic material, it interferes with skin respiration and causes inflammation of skin cells.

Hereinafter, the present invention will be described in detail with reference to preferred embodiments. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

FIG. 1 is a perspective view showing a urethral catheter fixing apparatus according to the present invention, and FIG. 2 is a perspective view showing an example in which a urethral catheter is installed in a urethral catheter fixing apparatus according to the present invention.

As shown, the urethral catheter securing device 10 according to the present invention includes a hemispherical end 20 at a front end, a body post 30 formed in a lengthwise direction from the hemispherical end, And a deforming portion (40) for changing the diameter of the column portion.

The hemispherical end 20 has a fixing hole 21 at the center thereof to allow the tubular body of the urethral catheter 60 to be inserted therethrough. The fixing hole 21 functions to prevent the urethral catheter tube body from moving in the longitudinal direction (axial direction) by pressing the tubular outer surface of the urethral catheter. Therefore, it is preferable that the fixing hole 21 has a fixing hole diameter smaller than the diameter of the urethral catheter by a predetermined size for strong coupling with the urethral catheter body.

For example, the diameter of the fixing hole 21 may be formed to be 1 to 10% smaller than the diameter of the urethral catheter 60 and fixed with a strong pressure to limit the movement of the urethral catheter. In this case, if the fixed ball is less than 1%, the force for compressing the urethral catheter is weak, and if it is formed as small as 10% or more, the discharge channel inside the urethral catheter becomes narrow due to excessive pressure, .

3A, the fixation hole 21 and the urethral catheter 60 may be formed by increasing the thickness of the hemispherical end 20 of the main body 21 having the fixation hole 21, as shown in FIG. 3A, The area of contact between the inner surface of the urethra catheter and the urethral catheter may be increased or a portion of the hemispherical end 20 where the fixing hole 21 is formed may be forwardly protruded as shown in FIG. Can be increased. At this time, the length of the fixing hole may be 2 to 10 mm to increase the contact area. In the case where the thickness is less than 2 mm, the improvement of the supporting force due to the increase of the contact area is insufficient, and in the case of 10 mm or more, the improvement of the supporting force is insufficient and the manufacturing cost is increased due to excessive thickness.

The body post 30 is formed integrally with the hemispherical end 20 and is formed long in the longitudinal direction from the rear surface of the hemispherical end,

The male pillar 30 is inserted into the inner receiving space through the opened portion of the rear end of the main pillar 30 to be positioned. At this time, it is preferable that the main body post portion is provided with a structure which can cope with the inner size of the penis because it has various sizes due to its own size or therapeutic gauze attached to the outer surface for treatment.

In addition, the material of each part of the urethral catheter fixing device is preferably made of a material harmless to the human body, and has a structural strength to some extent, so as to prevent the structure from being deformed by an external force. Typically, there are LDPE, HIPE, and PVC having a Shore hardness D40 to 80. Or may be formed of a silicon material including PDMS having an elastic force by itself.

Further, the rear end of the main body post may be formed to have a diameter slightly larger than that of the front end where the hemispherical end is formed, or a support base extending in a direction orthogonal to the longitudinal direction may be formed at the rear end, Structural changes are possible.

The deformed portion 40 is formed on a side surface of the main body column portion 30 so that the inner diameter of the main body column portion can be varied by expansion. The deformed portion 40 may be formed by forming a part of the side surface of the main column portion with a corrugated plate of a Lycra® type or by attaching a corrugated plate or a corrugated tube after the incision so that the folded portion of the deformed portion is expanded, .

The deformed portion 40 is formed by partially cutting the side surface of the main pillar portion in addition to the wrinkle shape and connecting the cut portion to the genital part inserted into the main body by the elastic force of the elastic band, So that it can be fixed. Using the elastic band in this way, the urethral catheter securing device can be attached and fixed to the human body without a separate fixing means.

4A, the deformation portion 40 may be formed on only one side surface of the end surface of the body column 30. [ In this case, the main body post 30 has a C-shaped cross section, and when an external force is applied, the portion where the deformed portion 40 is formed is expanded and the inside diameter is enlarged. In addition, as shown in FIG. 4B, the deformed portions 40 may be formed on both side surfaces of the main body column portion 30 so that both sides of the main body column portion 30 can be expanded, thereby changing the inner diameter in such a manner that the inner main body column portions are opened or closed.

As shown in FIG. 5, a plurality of ventilation holes 41 are formed in the deformation portion 40 to allow the air to flow into the interior of the deformation portion 40, thereby preventing the skin from being scratched, . For example, since the genital organs are wrapped with gauze, the gauze forms an air flow path between the skin and the main pillar portion, so that air introduced into the air through the air hole can be circulated through the air flow path of the gauze.

However, the deformed portion may be extended to a fixed hole, or may be extended to various lengths such as a portion where the opening and closing hole is formed when the opening and closing hole is formed.

In addition, the urethral catheter securing device 10 of the present invention may further include a coupling means 31 for limiting extension of the deformed portion. As the coupling means 31, various means such as a Velcro tape, a buckle, and a ring which can adjust the degree of tightness of the main body column can be applied.

As shown in FIG. 5, male and female coupling means 31 are formed on the body column portions 30 on both sides of the deformation portion 40 to limit the expansion of the deformation portion 40 by fastening of the coupling means . That is, when the pen is inserted into the receiving space of the main body post 30, the deformed portion 40 is expanded to form a large internal space. The urinary catheter fixing device 10 can be fixed to the human body without a separate body fixing means and can be easily worn corresponding to various sizes.

The coupling means 31 can be used in a form of one or more, preferably two to four, so as to be able to tightly contact the human body while preventing the extension of the deformed portion, It can also be formed at the end portion.

In the meantime, the urethral catheter securing device 10 of the present invention may further include an opening / closing port 22 for enlarging the size of the fixing hole 21.

5 and 6, the opening / closing port 22 is formed at a hemispherical end portion between the fixing hole 21 formed in the hemispherical end portion 20 and the deformation portion 40 of the main column portion, Quot; C "shape in a direction perpendicular to the longitudinal direction (axial direction) from the first-cut end, and a portion connected to the hemispherical end is formed on the hinge axis or the folding reference So that one side of the fixing hole 21 can be expanded.

When the size of the fixing hole 21 is enlarged in this manner, the main discharge pipe 61 of the urethral catheter 60 and the balloon extension pipe 62 and / or the washing water inlet pipe 63 branched from the main discharge pipe are positioned together, Since the expanded portion can easily pass through the fixing hole, the urethral catheter securing device 10 can be easily detached from the urethral catheter. That is, when replacing the therapeutic gauze, the urethral catheter securing device can be separated and mounted by passing the branched portion of the bulky urethral catheter through the extended fixation hole without the need to separate the urethral catheter. Therefore, since the movement of the urethral catheter can be minimized in the process of detaching and mounting the urethral catheter fixing device, the stimulation transmitted to the patient can be minimized, thereby preventing the pain from occurring and shortening the time for replacing the therapeutic gauze .

In addition, the opening and closing means 22 may be provided with a door fitting means 23 to prevent the opening and closing means 22 from being opened when the apparatus is mounted on the human body. A variety of known techniques can be applied to the opening and closing means 23, and the opening and closing opening can be prevented from being opened except when the urethra catheter fixing device is detached and attached by connecting the deformed portion with a Velcro tape that restricts expansion.

In addition, the deformable part 40 according to the present invention may be extended to a part where the opening / closing part 23 is formed in the hemispherical end part 20, so that the deformable part 40 can be expanded in the opened state to enlarge the size of the fixing hole.

7, the deformable portion 40 may be extended to the fixing hole 21, and a part of the deformed portion adjacent to the fixing hole may be cut to be used as a door. At this time, as shown in the drawing, the opening and closing means 23 is a full coupling method which connects both hemispherical ends of the deformed portion to each other to enable opening and closing of the opening and closing port. A partial coupling method in which only the opening / closing opening and closing is made, or a partial coupling method and a full coupling method are both formed.

8, the deforming portion 40 may be formed as a cutting line 42 cut to the portion where the fixing hole 21 is formed, so that the cut surfaces separated by the cutting line are overlapped with each other to be overlapped with each other The inner diameter can be expanded or contracted. At this time, it is also possible to form an opening / closing port on the hemispherical end portion of the portion close to the fixing hole 21 so that the opening / closing port is provided so as to overlap with the other hemispherical end surface, and the expansion of the inside diameter can be restricted through the opening / However, the structure overlapped by the cutting line can separate the penis and the catheter through the gap formed by widening the gap between the two cut surfaces on both sides forming the cutting line, so that it is not necessary to form a complex opening and closing opening.

The urethral catheter securing device 10 of the present invention configured as described above is a device for inserting the urethral catheter 60 through the urinary tract of the male genital tract and introducing therapeutic gauze to prevent urine from flowing out or inflammation discharge or bacterial penetration I wrap my penis through. Thereafter, the urethral catheter securing device 10 is inserted into the sanitary napkin, and the urethra catheter securing device is firmly fixed to the human body by tightening the tape with a belt, which is the engaging means 31 of the body post 30. In the fixed urethral catheter securing device 10, since the fixation hole 21 is fixed to the urethral catheter body by consolidation, the interval between the balloon in the bladder and the end of the urethral catheter securing device can be kept constant.

Also, when the gauze for internal therapy is periodically replaced, both the coupling means 31 are opened, the opening / closing port 22 is opened to enlarge the size of the fixing hole 21, and the tubular body of the urethral catheter 60 It is possible to easily remove the urethral catheter fixing device from the urethral catheter by passing the branched portion, and when the gauze replacement is completed, the dressing can be completed by reattaching in the reverse order to complete the dressing.
