DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stoma flange with a hole opening tool, which can easily make a hole suitable for an ostomy (patient = user).

[0002]

2. Description of the Related Art Costomy patients utilize a so-called ostomy system. The number of people who use the ostomy system by removing the rectum and related sites due to various diseases and the like is increasing. The ostomy system is a system for urination and defecation in which an ostomy flange is stuck to the skin at the artificial urinary opening or ostomy site so as not to leak, and a pouch (a bag for storing urine and stool) is attached. The stoma refers to the ostomy itself and sometimes refers to the protection plate around the ostomy.In the present invention, the stoma is used in the meaning of the ostomy itself, and in the sense of the protective flange attached to the periphery of the ostomy, the stoma is used. Used as a flange. Ostomy flanges (stoma protection plates) have been developed by the manufacturer in addition to those for the urinary tract and digestive system, and have various forms and structures. The basic configuration is a disk-shaped plate provided with an adhesive layer on the back surface. It is a plate that has a hole for inserting a stoma in the center and is used with an adhesive layer firmly adhered to the skin so as not to leak liquid. As the ostomy system, a one-piece pouch system, a two-piece system, and the like have been developed. The ostomy flange of each system has a disc-shaped basic structure and an adhesive layer formed on the back surface. Recently, there has been developed a two-piece system in which an annular standing edge is formed on the surface of a stomal flange to connect to a pouch (a bag body for storing urine and stool) with a single touch. The ostomy flange is used by an ostomy or caregiver or the like after making a hole having an appropriate inner diameter for each part thereof, and then attaching the hole to a user's body. Conventionally, as the means for making holes, there have been proposed a method using scissors and a means for making holes using a drill provided with a descending cutter.

[0003] Scissors that can be cut in a curved shape have been used for opening the stoma flange. The stoma flange before use is usually cut and sealed at the center so that a small hole with a diameter of about 1 Cm can be made, and is sealed and packaged. When opening and pressing this cut, a small hole is opened. However, a small hole is opened, and a small hole is cut into a hole of a required shape, and an unnecessary part is cut off to make a hole as needed. Some conventional stoma flanges are provided with a small hole at the center as an aid in drilling a hole and a groove provided concentrically with the small hole. This groove is used as a guide and cut with scissors to form a hole.

[0004] As a method not using scissors, Japanese Patent Laid-Open No.
No. 000-166952, "Stoma opening device" has been proposed. In this proposal, a cutter is guided around a central axis and descends to open a hole by threading a stoma (the plate itself is referred to as a stoma in the present invention). After opening the stoma, the stoma was taken out and set on the shaft of the opening tool to perform the cutting operation. A hole of a desired shape is formed by shifting the position by several degrees to create a delicate shape. Japanese Utility Model Laid-Open No. 3-118716, entitled "Punch Flange Drilling Tool" proposes a circular cutter with a lid. This invention is provided with a circular blade protruding from a stopper end surface (circular member) by a cutting thickness, and proposes a so-called circular punch.

[0005]

Conventional stoma flanges are provided with a small hole cut in the center to assist in drilling holes using scissors, and a groove is formed concentrically with the small hole. Some are provided. If a scissor is inserted from the small hole and cut appropriately, or cut along the groove with a scissor, a substantially circular large hole can be formed.
However, since the shape and size of the hole required for each ostomy differ, it is necessary to cut off a part of the inner edge of the opened hole to form an appropriate shape. Strictly speaking, the resection width is a few millimeters, which is a great task. In some cases, the presence of the groove did not allow for good resection.

On the other hand, Japanese Unexamined Patent Publication No. 2000-166952 "Stomal opening tool" requires an opening tool other than scissors, and is opened by cutting with a lowering cutter. It is necessary to purchase at a considerable price because it is a hole tool dedicated to the stoma. There are a few parts, the structure is complicated, there are still problems in rust prevention and cleaning, and the cut surface is twisted due to the configuration of opening by screwing. In several cutting operations, a wavy twisted surface may be formed on the adhesive layer on the back surface, or burrs may remain on the cut surface. Further, Japanese Utility Model Laid-Open No. 3-118716, "Pouch Flange Drilling Tool" is a circular blade with a lid-type stopper, and the drilling operation is set to use this tool, and the tool itself has a precise structure. A drilling tool is set on the stoma flange that has been requested and opened and exposed, and the tool is directly pressed, hit and opened.

[0007] It is very difficult to form a hole in the stoma flange because of the material of the stoma flange, the thickness of the adhesive layer, and the structural peculiarities of the release paper and the like attached to the surface to be attached. by. The layer structure of the relatively thick adhesive layer makes it difficult to carry out fine work with scissors, and it is even more difficult to cut the inner edge of the hole to a small size and to make fine correction cutting. In order to maintain cleanliness, the stoma flange needs to be replaced every one or two days, and such opening labor and labor are required every one or two days. Opening with scissors is a very painful task for ostomy. First, it is required to clean the whole work. When using tools such as disinfecting rooms and scissors, or using punches, it is necessary to disinfect those tools. Also, if the inner edge of the hole opened is not clean, it is a jagged edge, there is burrs, or if there is a wave or twist in the adhesive part, it will cause fine clearance, and it will cause dirt to accumulate during use. This was causing liquid leakage. That is, what is important in the opening of the stoma flange is the cleanness of the cut surface of the hole, the size of the hole, the position of the hole, and the like. Among them, the cleanness of the cut surface is important. This is because if the cut edge is jagged or if the lower surface is uneven, the probability of body fluid leakage increases. Therefore, it is necessary to provide a stoma opening tool whose edges are cut cleanly and the desired hole can be easily opened by the ostomy itself.In addition, the stoma opening tool can be cut more hygienic and the opening tool itself can be cleaned and repaired. It was developed with the intention of a configuration that does not need to be used.

[0008]

SUMMARY OF THE INVENTION The present invention proposes a stoma flange with an opening, wherein a cutter is placed on a stoma flange and packaged in a case that can be pressed. The cutter has a circular blade with a predetermined diameter or a slide cutter that can be circularly cut by pressing,
The upper surface is preferably a flat shape suitable for pressing. A spacer may be interposed between the cutter and the opening surface of the stoma flange to prevent unnecessary cutting. The pressure-variable case is composed of a cover that covers the surface and a base that covers the bottom surface, and the cover is made of a transparent material that is convex or roof-like and covers the stoma flange with an annular upright edge.
The base is composed of a release film or a thin transparent plate having a plurality of concentric annular grooves for guiding the circular blade of the cutter. It is necessary that the case is made of a material that can be pressed, that is, a material or a structure that transmits the pressing force to the internal cutter without attenuating when pressed from above the case.
In order to make the pressure variable structurally, the side periphery of the cover of the case may be made bellows-like or thin, or the whole cover may be made of a flexible material such as a soft material. For example, the cover is made of a soft transparent film. By the way,
The conventional cover is formed of a hard transparent plate, the base is formed of a thin release film to peel off and open the lid, but this material is reversed, the cover is a pressable release film, the base is a hard It is formed of a material. If the cutter having a required diameter is used by exchanging a combination of several kinds having predetermined diameters into a case and using a cutter having a required diameter, a hole having a desired diameter of the ostomy can be formed.

The stoma flange of the two-piece system is provided with an annular ridge with rubber packing for connection with the pouch, and this annular ridge is used to make use of the stomal flange having the annular ridge. At least one cutter having a circular blade with a predetermined diameter is fitted in the annular upright edge, wrapped in a pressable case, and struck from the top of the case to open a hole with a predetermined diameter. Suggest a flange. The cutter fitted inside the annular upright edge is guided in the descending direction and is stabilized. Thus, the present invention facilitates opening a stoma flange used in an ostomy system.

[0010] The stoma flange with a hole opening tool of the present invention comprises:
A hole with a predetermined diameter is made in the stoma flange by striking from above, but this can be done by hand, or by striking with a foot, or by striking with a hard object such as a hammer in the vicinity. Can be opened. You can open a hole even if you hit it several times with a fist. Anyone can open the hole more easily by using a dedicated pressing machine described later. The pressing machine is mounted on the base with a link so that the descending plate can be moved up and down by the handle.The cutter having an appropriate diameter can be selected from among the cutters below the descending plate, and can be attached with double-sided tape or the like. . That is, this press can be used as a normal punch if a cutter is attached.

The cutter of the present invention is of a disposable type. Of course, it can be used several times, but in principle it may be discarded after opening. Further, the cutter is not limited to a circular cutter, and may have any configuration as long as the cutter can cut the hole by pressing the case.

FIG. 6 is a side sectional view showing a state where one cutter 2 is placed on the stoma flange 1 and packaged in the case 3. FIG. 7 is a perspective view of a pressing machine 9 which is an auxiliary device for pressing, and presses and presses the stomal flange with the opening tool of the embodiment of FIG. FIG. 8 is a side view in which a spacer 4 having antibacterial property or the like is interposed between the cutter 2 in FIG. 6 and an opening surface of the stoma flange 1 and stored in the case 3. FIG. 9 is a different cutter of a so-called slide cutter. 2 is a side view of the embodiment in which the device 2 is installed. A variable pressure case provided with a cutter 2 provided with a hanging blade 25 supported by a flexible rod 24 which is slidably and removably inserted into a through hole of a block 23 provided slidably and detachably on an annular upright edge of the ostomy flange 1. It is packed in 3.

As shown in FIGS. 1, 2, 3, and 4, a stoma flange with a hole is provided on a circular stoma flange 1 having an adhesive layer formed on a back surface thereof. Is mounted and packaged in a case 3 that can be pressed. Transparent case 3
Therefore, the internal cutter 2 and the stoma flange 1 can be visually recognized. Alternatively, as shown in FIG. 9, the cutter 2 is a hanging cutter supported by a flexible rod 24 which is slidably inserted into a through hole of a block 23 which is slidably and detachably provided on the annular upright edge 10 of the stoma flange 1. The slide cutter 2 constituted by 25 is provided, and is wrapped in a case 3 capable of being pressed.

The stomal flange 1 is, for example,
A disc-shaped plate with a diameter of 120 mm, with a diameter of 90 mm on the back
An adhesive layer having a thickness of 1 mm is provided in a circular shape of mm. It has a configuration in which a ring-shaped thin adhesive layer having a width of 15 mm is provided therearound. Each adhesive layer adheres directly to the skin to prevent liquid leakage. A release paper to be peeled off at the time of use is stretched on the back surface adhesive layer so that it can be separated into a thick adhesive layer portion and a thin outer ring adhesive layer. At the center of the circular adhesive layer having a diameter of 9 Cm formed on the back surface, a notch for forming a small hole having a diameter of 10 mm is provided. In addition, an annular upright edge 10 having a diameter of 70 mm and a height of 8 mm with a rubber packing 11 is provided on the surface of the stoma flange 1 of the two-piece system for connection with a pouch (bag for discharging body fluid) not shown. ing. The inner surface of the annular rim 10 is a coated open surface, and the periphery of the annular rim 10 is a mesh fabric. This dimension is an example, but at the time of sale, the stoma flange 1 is sold in a transparent case 3 having a thickness of about 10 mm so as to cover the shape of each stoma flange for hygiene reasons.

A cutter 2 for making a hole in such a stoma flange 1 is placed. Cutter 2 having circular blade 21
Is pressed from above the case 3 to form a circular hole to be opened. As will be described later, the cutter 2 supported by the flexible rod 24 presses the finger from above the case 3 and pushes the stoma flange 1 with another fingertip. When rotated along the concave portion of the case 3, a circular cut can be made.

Now, as described above, the stoma flange 1 of the normal two-piece system is provided with the annular upright edge 10 with the rubber packing 11 for connection with the pouch, and the circular inside of the annular upright edge 10 is opened. It becomes a hole surface. The case 3 for accommodating the stoma flange 1 is a packaging form that is indispensable for hygiene. The conventional case is for protecting the items inside with a transparent plastic material, and has a form and strength that maintain a proper shape. Was. However, the present invention has a feature that the case 3 is configured as one element of the pressing means for opening. The cover 31 of the case 3 is variable in pressure (a material or shape that is easily crushed) at the same time as guiding the hole while holding the cutter 2 from above and supporting the cutter 2 at a predetermined position during the hole opening operation. That is the condition.

The height of the cutter 2 is higher than the height of the annular rim 10 by at least the thickness of the adhesive layer, and the upper surface of the cutter 2 is preferably a flat shape suitable for pressing. Further, it is preferable to prevent a sudden cutting by interposing a spacer 4 between the cutter 2 and the opening surface of the stoma flange 1. By making the spacer 4 from an antibacterial and sterilizing material, it becomes more hygienic.

The variable pressure case 3 comprises a cover 31 for covering the front surface and a base 31 for covering the bottom surface.
Reference numeral 1 denotes a convex or roof-shaped transparent material that can be pressed to cover the stomal flange 1 with the annular upright edge 10. The base 32 includes a release film and a plurality of concentric circular guides that guide the circular blade 21 of the cutter 2. And a transparent plate having an annular groove 34 formed thereon. In the present invention, the shape of the upper surface of the case 3 is specified by a shape suitable for a state where the cutter 2 is loaded. The shape conforms to the height and shape of the protrusion of the cutter 2.

FIG. 1 and FIG. 4 show a case where large, medium and small ring-shaped cutters 2 are sequentially combined and loaded, and a plurality of cutters 2 are combined in a stepwise manner in the order of a small cutter 2, a middle cutter 2, and a large cutter 2. Things. For this reason, since the side surface of the case 3 has a step-like shape, a step-like cover shape is selected in a side view suitable for it. In the case of the slide cutter type cutter 2 as shown in FIG. 9, a shape in which the upper surface of the cover 31 that covers the annular upright edge 10 is flat is selected.

The case 3 is required to be variable in pressing, that is, when pressed from above the case 3, it must be made of a material or a structure that transmits the pressing force downward to the internal cutter 2 without attenuating. In order to make it structurally variable in pressure, the side peripheral portion 33 of the cover 31 of the case 3 (each side peripheral portion in the case of a staircase) may be formed in a bellows shape or a thin shape, or the entire cover 31 may be made of a thin material or a soft material. The material is made variable by pressing, for example, by forming it. For example, the cover 31 is made of a soft transparent film. By the way, conventionally, the cover 31 on the upper surface is generally formed of a hard transparent plate, and the base 32 is formed of a thin release film to peel off and open the lid,
Conversely, the cover 31 is a release film that can be pressed,
The base 32 may be formed of a hard material. Base 3
2 is formed with an annular groove 34 corresponding to the cutter 2 and
It is also preferable to make the cut edge sharper by cutting inside. In order to prevent the circular blade 21 from breaking through the base 32, an appropriate stopper may be provided or the base 3 may be provided.
2 may be formed of a harder material than the circular blade 21.

The cutter 2 shown in FIG. 1 is a combination of several kinds of predetermined diameters, for example, large, medium and small, and is formed by combining them into a hollow ring shape in plan view. The cutter 2 is provided with a center hole for combination, and is inserted into the center hole one after another and assembled. The illustrated cutter 2 is set higher in the order of small cutter 2, middle cutter 2, and large cutter 2. The cutter 2 is merely mounted on the annular upright edge 10 and is replaceable. The cover 31 of the case 3 is covered and loaded at a predetermined position. The cutter 2 with a small diameter
Since it is at the center, if the upper part is pressed or hit, a small opening is formed first, and if the hitting is performed successively, the opening with a larger diameter is formed sequentially. Of course, the cutter 2 having a necessary diameter can be selected and hit.

The cutter 2 shown in FIG.
In this example, the circular blade 21 is horizontal (a), inclined (b), and formed with a protruding blade at an appropriate position (c). The slanted blade is cut sequentially from the point where the blade hits, and the one where the protruding blade is formed at another appropriate place is the one that opens the hole after inserting the protruding blade, and the contact point with the stoma flange 1 becomes small. It is easy to cut and does not require force. The cutting force of the cutter 2 is related to the sharpness of the blade, but it is only necessary to be able to press and cut the flexible adhesive layer.

The concrete configuration of the cutter 2 having the circular blade 21 is as follows: (1) The cutter 2 is made of a hard synthetic resin, and has a striking flat portion 22 on an upper surface and a sharp circular blade 21 on a lower end. The flat portion 22 does not need to be the entire upper surface, but the pressing portion preferably has a flat shape or a dome shape so as to be suitable for pressing, and is provided at least above the circular blade 21. (2) The cutter 2 is dimensioned to fit inside the annular upright edge 10 of the stomal flange 1 having the annular upright edge 10 with the rubber packing 11, and is guided by the annular upright edge 10 in the descending direction. (3) There is a height protruding from the annular upright edge 10. Is requested. Further, the cutter 2 has a circular blade 2
However, the present invention is not limited to the above-described one, and may be one that can be cut by pressing the case 3 such as a so-called slide cutter disclosed in the present invention.

FIGS. 6 and 8 are exploded cross-sectional views showing a state in which one cutter 2 is placed on the stoma flange 1 and packed in a case 3 that can be pressed. The cutter 2 having the circular blade 21 according to the order of the ostomy is loaded. This means that one of the large, medium and small cutters 2 is combined with the case 3 that can be pressed. When the cutter 2 is set alone, a part in the hollow portion of the circular blade 21 may be reinforced in a honeycomb shape or a cross shape.

If there is a fine adjustment, the ostomy selects a size that fits the stoma, presses the cutter 2 from above to open a hole, and if necessary, the position of the cutter 2 Is shifted and pressed again to perform fine adjustment of the edge size.

FIG. 8 shows a case in which a spacer 4 such as an antibacterial paper piece is interposed between the cutter 2 and the opening surface of the stoma flange 1 and housed in the case 3. Spacer 4
Is a disinfecting piece that prevents accidental cutting and for sterilization and antibacterial. However, a material made of an antibacterial mesh or the like and easily cut by pressing is preferable.

FIG. 7 shows an auxiliary device for pressing, and FIG.
It is a perspective view of the press machine 9 which puts and presses the stoma flange with an opening tool of embodiment of this invention as it is, and opens a hole. Originally, the stoma flange with the opening tool is opened by simply pressing, but it is convenient to use the pressing machine 9 when a plurality of sheets are continuously opened. Pressing and opening may cause uneven cutting even before the ostomy is used to adjusting the force, but if the pressing machine 9 is used to assist in such a case, the pressing force will be substantially constant, and There is an advantage that the periphery is made uniform and sharp. If the pressing machine 9 is used, the holes can be continuously and easily opened even with a weak force. The pressing machine 9 is provided with a link 94 such that the lowering plate 92 is vertically moved up and down by a handle 93 on a base 91.
It was attached with. A desired hole is formed by placing the case 3 together with the pressing machine 9 and lowering and pressing the lowering plate 92. Although not shown, the lowering plate 92 of the pressing machine 9 can be configured as a jack that descends stepwise, so that the case 3 having a stepped upper surface as shown in FIG.
Can also be pressed stepwise.

Further, the cutter 2 having an appropriate diameter can be selected on the lower surface of the descending plate 92 of the pressing machine 9 and can be attached with a double-sided tape or the like. That is, the press 9 can be used as a normal punch. Case 3
The stoma flange 1 taken out from the base 91,
On the other hand, the cutter 2 having a desired diameter can be attached to the descending plate 92 with a double-sided tape or the like, and the handle 93 can be operated to press the cutter 2 to open the hole. In this case, the shape of the hole can be finely adjusted as needed by slightly moving the stomal flange 1 after the first opening and pressing it again.
Even if the cutter 2 in use is damaged, etc.
Is attached to each stoma flange with opening,
It is easy to replace only the cutter 2. The base 91 is designed with consideration such as forming a concave surface for placing the stoma flange 1 at a predetermined position and forming a film with a resin having appropriate hardness.

FIG. 9 is a side view of a stoma flange with an opening provided with a different cutter 2 of a so-called slide cutter type embodiment. The cutter 2 in FIG. 9
The hanging blade 25 is supported on a flexible rod 24 which moves left and right in a through horizontal hole formed in an inverted concave block 23 slidably and detachably provided on the annular upright edge 10 of the stoma flange 1. is there. The cutter 2 has a transparent case 3 that can press the upper part of the hanging blade 25 and that can be pressed.
Annular edge 1 of stoma flange 1 with cover 31
Locked to zero.

The hanging blade 25 is attached to the flexible rod 24 and has a sharp cutting edge at its tip. The flexible rod 24 is inserted into the through-hole of the block 23, and is configured to be able to be moved forward and backward by a finger and stopped at an arbitrary position. The diameter of the hole to be opened in the stomal flange 1 is determined by the degree of advance of the rod 24, and the diameter of the hole can be arbitrarily adjusted. When opening a large diameter hole, use rod 24
Is retracted, but if the rear end is in the way, it may be cut off. The through-hole is for sliding the rod 24 and may be of a frame type for guiding as shown in the enlarged view of FIG. Then, the flexible rod 24 is bent by pressing from above, and the hanging blade 25 can be lowered. The cutting edge of the hanging blade 25 has a length that allows the rod 24 to bend into the stoma flange 1 due to the curvature of the rod 24, and the thumb of one hand to the case 3.
Is pressed from above, inserted into the stoma flange 1 and supported from below by the index finger, the case 3 is opened slightly, and the stomal flange 1 is sandwiched between the thumb and the index finger of the other hand, and the cover 3 of the case 3 When the blade 25 is rotated to feed along the stoma flange 1 with a predetermined diameter.
Will be opened. The ostomy flange 1 is rotated with the other fingertip, and the thumb of one hand presses the hanging blade 25 to pierce the stoma flange 1 and make an incision. It is important to use it in a balanced manner. Since this opening is a method of making an incision instead of pressing from above, the incision is clean and the work is easy once it gets used. The cutter 2 can be manufactured at a low cost. In the case of such a configuration in which the cutting is performed using the hanging blade 25 for cutting, the spacer 4 is preferably interposed at the time of packaging. Also, for safety when cutting,
It is important that the base 32 of the case 3 be made of, for example, ABS resin if possible to enhance safety.

As described above, since the stoma flange with a hole tool according to the present invention is obtained by packing the stoma flange 1 provided with the cutter 2 in the pressable case 3, the ostomy can be opened only by simple pressing. It can be perforated, thereby relieving the trouble of the perforating operation by scissors as in the conventional case.
