MODE FOR INVENTION

(9) Hereinafter, embodiments of the present invention are described in detail with exemplary drawings. When components are given reference numerals in the drawings, the same components are given the same reference numerals even if they are shown in different drawings. Further, in the following description of embodiments of the present invention, when a detailed description of well-known configurations or functions is determined as interfering with understanding of the embodiments of the present invention, they are not described in detail.

(10) Further, terms first, second, A, B, (a), and (b) can be used in the following description of embodiments of the present invention. The terms are provided only for discriminating components from other components, and the essence, sequence, or order of the components are not limited by the terms. When a component is described as being connected, combined, or coupled with another component, it should be understood that the component may be connected or coupled to another component directly or with another component interposing therebetween.

(11) A catheter fixture for a PEG tube of catheters T is exemplified in the following description. Obviously, the catheter T according to the present invention may be applied all of various catheters T.

(12) A catheter T is described first for the convenience of description. The catheter T, which is a kind of medical tube, is made of a flexible material such that a portion is inserted into the body of a patient and the other portion is left outside the body. A syringe etc. is connected to the portion of the catheter T left outside the body of the patient to inject medicine or food into the body through the catheter T.

(13) A catheter fixture is combined with the catheter T. The catheter fixture allows the catheter T to be fixed to a portion of the body of a patient and they may be combined by fitting the catheter T through the fixture.

(14) The catheter fixture is clearly shown in the perspective view of FIG. 2. As shown in the figure, the frame of the catheter fixture is formed by a base plate 10. The base plate 10 is a substantially thin plate and is a part to be actually brought in contact with the skin of a patient. Obviously, a gauze etc. may be inserted between the base plate 10 and the skin of a patient. In this embodiment, although the base plate 10 is a circular plate, but it is not limited thereto and may be formed in various shapes of plates such as an ellipse or a polygon.

(15) A base hole BH is formed through the base plate 10. The base hole BH, which is a part through which the catheter T passes, has an inner diameter the same as or larger than the outer diameter of the catheter T. The base hole BH is formed vertically through the base plate 10.

(16) The fixture body 20 is formed on the top of the base plate 10. The fixture body 20 is integrally formed with the base plate 10, protruding at a predetermined height from the base plate 10. That is, the base plate 10 and the fixture body 20 are made of the same material in one unit, and they are made of silicon in this embodiment. The catheter fixture may be made of flexible materials such as silicon.

(17) The fixture body 20 has a guide fence 25 at a side. The guide fence 25 protrudes upward from a side of the base plate 10. The guide fence 25 supports a side of the catheter T extending vertically through a first guide hole GH1 to be described below or moving horizontally through a second guide hole GH2.

(18) The guide fence 25 is formed close to the base hole BH and the first guide hole GH1 connected to the base hole BH is vertically formed at a side of the guide fence 25. More accurately, the first guide hole GH 1 is formed between the guide fence 25 and a cover 30 to be described below. The first guide hole GH1 is connected to the base hole BH and extends in the open direction of the base hole BH1, so, as shown in FIG. 7, when the catheter T passes through the first guide hole GH1, the catheter T can extend in the insertion direction into the body of a patient. In this state, medicine or food can be injected from an end of the catheter T.

(19) The cover 30 is formed at a side of the guide fence 25. The cover 30 protrudes upward from the base plate 10 with one end directed back toward the base plate 10. That is, the cover 30 is rounded such that the outer surface curved and covers the second guide hole GH2 thereunder. As shown in FIGS. 4 and 5, the cover 30 may continue from the guide fence 25.

(20) The cover 30 forms the second guide hole GH2 and holds the upper surface of the catheter T guided through the second guide hole GH2 to prevent the catheter T from separating from the second guide hole GH2. That is, the second guide hole GH2 is formed between the cover 30 and the base plate 10.

(21) As shown in FIG. 6a, the second guide hole GH2 gradually declines as it goes away from the end connected to the base hole BH. In this embodiment, the top 35 of the cover 30 gradually declines as it goes away from the guide fence 25, so the guide hole GH2 also declines. Accordingly, the catheter T can be bent slight down from the right angle when passing through the second guide hole GH2, so backflow through the catheter T can be more stably prevented.

(22) The catheter T passing through the declining second guide hole GH2 is naturally guided gradually closer to the skin of a patient, so the catheter T can be easily fixed to the patient's skin. For reference, in FIG. 6a, the arrow {circle around (1)} indicates the direction in which the catheter T is guided into the second guide hole GH2 and the arrow {circle around (2)} indicates the direction in which the catheter T is guided into the first guide hole GH1.

(23) As shown in FIGS. 3 and 5, the second guide hole GH2 is laterally open. That is, a predetermined space S is defined between the cover 30 and the fixture body 20, so a portion of the second guide hole GH2 is open to the outside. Further, a portion of the catheter T can be easily inserted into and taken out of the second guide hole GH2 through the space S.

(24) Since the catheter fixture is made of a flexible material in this embodiment, a user can open the second guide hole GH2 by holding and opening an end of the cover 30 upward (in FIG. 5) from the space S and then insert or take the catheter T into or out of the second guide hole GH2.

(25) A projective grip 32 is formed at a side of the cover 30. The projective grip 32 protrudes from a side of the cover 30 perpendicular to the longitudinal direction of the second guide hole GH2 so that a user can easily open the cover 30 by holding it.

(26) As shown in FIG. 5, the guide fence 25 may protrude from the base plate 10 less than the cover 30. This is for more easily handling an end of the catheter T through the gap formed by the height difference between the cover 30 and the guide fence 25.

(27) Meanwhile, as shown in FIG. 6a, a third guide hole GH3 may be formed through the guide fence 25 to be open to the outside opposite to the second guide hole GH2. The third guide hole GH3 allows the catheter T to extend opposite to the second guide hole GH2. The third guide hole GH3 may have a different diameter from the second guide hole GH2 so that the catheter fixture can be applied to catheters T having various diameters. Non-stated reference numeral 12 indicates through-holes formed through the base plate 10 and the fixture body. The through-holes 12 decrease the contact area between the skin of a patient and the catheter fixture and increase the contact area between the skin of a patient and air.

(28) A process of using the catheter fixture according to the present invention is described hereafter.

(29) First, a user inserts a portion of the catheter T into the body of a patient and then fixes the catheter fixture on the patient's skin. In this state, the catheter T exposed out of the patient's body extends through the first guide hole GH1 of the catheter fixture, that is, as shown in FIG. 7, the catheter T extends vertically through the first guide hole GH1.

(30) In this state, food or medicine is injected from a first end of the catheter T and is supplied into the patient's body through the catheter T.

(31) When injection of food or medicine is finished, the user blocks the first end and puts the catheter T into the second guide hole GH2. In more detail, when the cover 30 of the catheter fixture is elastically deformed and the space S between the cover 30 and the base plate 10, that is, the inlet of the second guide hole GH2 is widened, the catheter T can be easily inserted into the second guide hole GH2.

(32) Accordingly, as shown in FIG. 8, the catheter T is partially bent at a right angle and backflow of the food or medicine can be more stably prevented at the bent portion. Further, since the catheter T extends in parallel with the patient's skin by the catheter fixture, the user can more easily fix a portion of the catheter T to the patient's skin after finishing injecting food or medicine.

(33) If necessary, the user may fix the base plate 10 to the patient's skin using an adhesive such as an adhesive tape.

(34) As described above, according to the present invention, since it is possible to extend the catheter T using one catheter fixture, it is possible to inject food or medicine through the catheter T and prevent backflow of the food or medicine.

(35) Even if all components of the embodiments of the present invention were described as being combined in a single unit or operated in combination with each other, the present invention is not limited to the embodiments. That is, one or more of all components may be selectively combined to operate within the scope of the present invention.
