Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field] The present invention relates to a device for reliably and safely fixing a catheter tube on the skin of a patient.

[Conventional technology]

In the treatment of patients, inserting a catheter tube into the affected area in order to drain body fluids such as pus and inject drugs into the affected area, guide the other end percutaneously outside the body, and leave it in place for a long period of time is a medical practice. It is often done in places like For example, in recent years, percutaneous transhepatobiliary drainage, in which a relatively hard tube is percutaneously placed in the hepatobiliary tract, has been used not only to alleviate jaundice and treat biliary tract infections, but also to treat bile duct obstruction caused by malignant tumors and in the elderly. With the increase in the number of cases, it has become actively used as a treatment method in place of surgery. Percutaneous transhepatic biliary drainage is often performed over a long period of time, and during this period, it is an important point in treatment and nursing to properly secure the indwelling catheter tube on the skin. This is also important for reducing patient pain and discomfort.

Conventionally, in order to fix a catheter tube onto a patient's skin, a method has been used in which a thick, soft tube is wrapped with a bandage or surgical tape and the end is adhesively fixed to the skin. Although this method has the advantage of not requiring any small tools and can be performed easily, it has the inconvenience of causing the tube to shift, and has the disadvantage that it cannot be sufficiently fixed to harder tubes.
For harder tubes, the general method is to roll gauze into a pillow, place the tube on top of it, and fix it on the skin with a bandage. However, with this method, when the patient moves, the tube bends or puts pressure on the patient, causing pain, or the tube often falls out or shifts, resulting in poor fixation, which causes the patient to feel pain, pressure, or discomfort. There was a drawback of giving. The main cause of poor fixation is that when the patient changes position, external forces are applied to the tube using conventional methods, causing the tube to move or bend. was expected to appear.

In particular, in the percutaneous transhepatic biliary drainage method, the catheter tube protrudes vertically from the skin, and in order to drain body fluids smoothly, the tube perpendicular to the skin is gently curved into the skin without bending the tube. It is desirable to curve it with an appropriate curvature so that it is parallel to the curve and hold it fixedly.
This fixing device (pillow) has a weak force in keeping the tube curved and fixed with the conventionally used rolled gauze, and when the patient changes his or her body position, external force is applied to the tube or the tube moves out of position. There was a tendency to

[Purpose of invention]

The object of the present invention is to provide a fixing device for a catheter tube that improves the above-mentioned drawbacks, that is, a catheter tube that can be curved and held at an appropriate curvature from the skin protrusion of the catheter tube.
Even when the patient moves, the tube does not bend or put pressure on the affected area, the skin at the tube insertion site remains clean, and it is small and lightweight, which reduces the pain associated with fixing the catheter tube for the patient. It is an object of the present invention to provide a device for fixing a catheter tube on the skin, which does not cause discomfort, discomfort, or pressure, and which is simple in terms of fixing technique for medical personnel and has excellent handling properties.

[Structure of the idea]

That is, the present invention comprises a main body block made of a semi-spherical or semi-ellipsoidal elastic foam (sponge) and an adhesive layer provided on the flat bottom surface of the main body block. A vertical cut is provided in the spherical surface of the main body block over the entire surface of one side from near the center of the body block, and a catheter tube is formed on the spherical surface of the main body block, extending from the top toward the opposite side of the cut to the outer periphery of the bottom surface. At the same time, a groove is provided that serves as a holding part for the main body block, and a groove is provided that extends from near the center of the bottom of the main body block toward the top side, penetrates the adhesive layer and the main body block, and curves toward the opposite side of the cutout near the top side opening. , a catheter tube fixing device characterized by having a passage that is smoothly connected to the groove in an arc shape and serves as a housing section for the catheter tube, and the main body block is directly attached to the patient's skin by means of an adhesive layer on the bottom surface. It can be pasted, and the catheter tube can be accommodated and fixed in the passage by expanding the cut of the main body block, and the catheter tube protruding from the top of the main body block can be fixed in place by the groove provided on the arcuate and spherical surface on the top side of the passage. By placing the catheter tube along the skin protrusion, the catheter tube can be curved and held at an appropriate curvature from the skin protrusion.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

The catheter tube 9 is curved on the patient's skin 2 using the main body block 3 as a pillow, and fixed on the skin with a bandage 10. Furthermore, the main body block 3 may be covered with a surgical drape 11 to strengthen and stabilize the fixation.

Fig. 2 is a top view of Fig. 1, Fig. 3 is a sectional view taken along line A-A' of Fig. 2, and Fig. 4 is a cross-sectional view taken along line B of Fig. 2.
It is a sectional view at -B'. Fixing tool 1 of the present invention
The device consists of a main body block 3 made of an elastic foam (sponge) with a flat bottom and a semicircular or semielliptical shape, and an adhesive layer 4 laminated on the bottom and attached directly to the patient's skin. There is. The material of the main body block 3 is preferably a semi-rigid or soft elastic foam that uses synthetic resin-based or rubber-based foam and has a compressive rebound force that is comparable to the bending rigidity of the catheter tube 9. . Specifically, polyethylene foam, semi-rigid polyurethane foam, soft vinyl chloride resin foam, etc. can be used, and they are integrally molded. The adhesive layer 4 is preferably made of a material that has strong adhesion to the skin and is less irritating to the skin and does not cause skin irritation or sagging, and it is preferable to use adhesive for bandages or skin protection materials for stomas. good. Moreover, the adhesive layer 4 is protected by pasting release paper before use.

The fixing tool 1 has an adhesive layer 4 on the bottom surface extending from the vicinity of the center of the bottom surface toward the top side of the main body block 3.
A cylindrical hole or passageway 5 is provided perpendicularly or slightly obliquely to the adhesive layer 4 and the main body block 3 to serve as a storage area for the catheter tube, and the diameter of the hole is determined according to the catheter used. Although it is determined according to the outer diameter of the tube 9, it is preferable that the hole passageway 5 has a diameter slightly smaller than the outer diameter of the tube in order to increase the force for holding and fixing the accommodated catheter tube.

Also, a cutout 7 is provided extending from the passage 5 to the entire one side of the main body block 3 for storing the catheter tube 9 into the passage 5 from the outside. When the main body block 3 has a semi-elliptic spherical shape, the cut 7 is preferably provided in the longitudinal direction of the main body block 3.

The inner surface 8 (see FIG. 3) of this cut 7 is planar and can be used for practical purposes, but it is preferable to provide a linear protrusion on one side of the inner surface 8 by a conventional means.
It is also possible to provide a mechanism in which a concave groove is provided on the other surface facing the other surface, and when the cut 7 is closed, the linear protrusion and the concave groove fit into each other to maintain the closed state.

Further, the catheter tube 9 housed in the passage 5 is arranged along the surface of the main body block 3, but the catheter tube 9 is placed along the surface of the main body block 3, and the catheter tube 9 is placed along the surface of the main body block 3 from the opening 6 on the top side of the passage 5 to the spherical surface of the main body block 3 in the opposite direction from the cutout 7. above,
It is preferable to provide a groove 12 having a continuous semicircular cross section all the way to the outer peripheral edge of the bottom surface so that the catheter tube 9 can be stably held. In addition, in order to curve the catheter tube 9 smoothly from the opening 6 along the surface of the main body block 3,
The passage 5 is curved toward the opposite side of the slit 7 near the opening 6, and the groove 12, which serves as a holding portion for the catheter tube 9, is formed in a continuous smooth arc shape as a whole. As a result, the catheter tube 9 that is housed and fixed can be easily bent into an arc shape, and the catheter tube can be fixed to the patient's skin 2 using the main body block 3 as a pillow, so that the main body block 3 is formed. Combined with the elasticity of the foam, this reduces excessive external force being applied to the catheter tube even when the patient changes position.

The procedure for a medical worker to attach the fixing device 1 according to this embodiment to the patient's skin is to first disinfect and dry the skin 2 around the catheter tube 9 protruding from the patient's skin. Next, the protective release paper of the adhesive layer 4 on the bottom of the sterilized fixture 1 is removed, the cutout 7 is opened, and the catheter tube 9 is removed.
The catheter tube is inserted into the passage 5, the cut 7 is closed, and the top of the main body block 3 is pressed down to adhere the adhesive to the skin 2. aisle 5
The catheter tube 9 protruding from the top side opening 6 of the catheter tube 9 is inserted into the groove 1 provided on the surface of the main body block 3.
