Description

  The present invention relates to a therapeutic material for umbilical hernia.

Infants and infants often have umbilical hernia, which is the bottom of the umbilicus that forms in the abdomen after the umbilical cord is removed, and the umbilical ring is the part of the umbilical ring that connects the umbilical cord and the infant's abdominal cavity. Occurs when the intestinal tract in the abdominal cavity protrudes from the patency of the umbilical ring.
Conventionally, this treatment of umbilical hernia includes a method in which the hernia protruding from the patency hole of the umbilical ring is pushed into the rectus abdominis with a finger and then a cotton ball or the like is pushed into the umbilical fossa and fixed with tape. It was done.

  However, if the push-in of the cotton ball or the like is weak, when the baby or the like suddenly rises and the pressure in the abdomen such as the intra-abdominal pressure temporarily rises, the cotton ball packed in the umbilical fossa is pushed out and slips. May be unable to provide reliable treatment. Therefore, it is necessary not only to apply cotton balls etc., but also to push it firmly so that it does not slip, and then fasten it with tape. There were inconveniences such as being unable to call.

  In addition, a treatment instrument in which a spherical protrusion formed of silicone rubber or the like is combined with a flat plate has been proposed (Patent Document 1). In such a treatment instrument, a spherical protrusion is inserted into the umbilical cavity, and a flat plate is placed on the skin surface around the umbilical cavity and fixed with a bandage, and the protrusion is securely inserted into the umbilical cavity. However, when this material is also used, there is a risk that the projections will concentrate on the patency of the umbilical ring and damage the skin of the umbilical fossa.

Utility Model Registration No. 3172156

  The present invention reliably holds the intestinal tract pushed inward from the patency of the umbilical ring in the rectus abdominis muscle without causing an action such as damaging the skin of the umbilical cavity, and increases the pressure in the abdomen. It is intended to provide a treatment material for umbilical hernia that receives and cushions against the strong force that is going to pop out.

  The present invention is used by being inserted into the umbilical fossa, and a tip protrusion that reliably closes the patent hole of the umbilical ring, and a body surface side that is behind the tip protrusion, When the pressure increases, a posterior protrusion is provided to receive the strong pressure and buffer it, thereby providing a therapeutic material for umbilical hernia.

  This treatment material pushes the protruding intestinal tract into the umbilical ring patency hole when the umbilical hernia has occurred, and closes the patency of the umbilical ring with the tip protrusion so that the intestinal tract is placed in the rectus abdominis muscle. Can be stored securely. Further, by receiving and buffering the strong pressure from the abdomen by the posterior process, the sealing action of the intestinal tract by the distal process can be maintained, and the umbilical hernia can be reliably treated.

  The umbilical hernia treatment material 1 of the present invention includes a tip protrusion 7 that closes the patency hole 5 of the umbilical ring and a rear protrusion 9 that is formed larger than the base 8 of the tip protrusion 7. In FIG. 1, the tip 11 of the tip projection 7 is formed in a dome shape with an arcuate shape, and a rear projection 9 having a thickness projecting laterally from the base 8 of the tip projection 7 is formed. ing. The posterior protrusion 9 has a rounded 19 side portion 21 following the contact surface 17 whose upper surface is spherical, and comes into contact with the upper surface of the umbilical fossa 13 and the skin surface around the abdomen 15. And has a back surface 23 facing the contact surface 17.

  The umbilical hernia treatment material 1 may be formed of a buffer elastic body having moderate elasticity and a certain degree of hardness enough to block the patent hole 5 of the umbilical ring. The shock-absorbing elastic body preferably has a low skin irritation that does not irritate the delicate skin of an infant.

  Examples of the buffer elastic body include, for example, synthetic rubber such as urethane resin, polyethylene resin, silicone resin, and silicone rubber, other rubber-like elastic bodies, urethane resin foam, polyethylene resin foam, foam such as silicone rubber, and other sponges. Fiber elastic bodies such as elastic bodies, compressed cotton, non-woven fabrics, and laminates of non-woven fabrics can be used. Further, various additives having low skin irritation can be used for these elastic bodies in order to obtain appropriate characteristics.

  Normally, the umbilical hernia treatment material 1 is often integrally formed of the above materials, but can also be integrally formed by using different materials for the distal protrusion 7 and the rear protrusion 9.

  The hardness of the buffer elastic body that forms the umbilical hernia treatment material 1 is a compression stress when a cylindrical shape having a diameter of 12 mm and a height of 10 mm is compressed by the treatment material by 5 mm in height. Furthermore, it is 6N / 12mmφ × 5mm or more and 280N / 12mmφ × 5mm or less, preferably 7N / 12mmφ × 5mm or more and 250N / 12mmφ × 5mm or less. If the compressive stress is smaller than this, when the hernia is pushed in or when the pressure in the abdominal cavity such as the pressure in the abdominal cavity increases, it may be pushed out like a cotton ball and the compressive stress may be shifted. Larger ones are too hard and can damage the skin.

  The umbilical hernia treatment material 1 should have different sizes depending on the size of the infant's body, the shape of the umbilical fossa 13, the pressure in the abdomen, the size of the patent hole 5 of the umbilical ring, etc. Therefore, it is advisable to prepare a plurality of items of different sizes and use a size suitable for the infant.

  In the example shown in FIG. 1, the length from the dome-shaped tip 11 of the tip projection 7 to the base 8 is about 15 mm, the diameter of the base 8 is about 20 mm, and the thickness of the rear projection 9 is about 10 mm. The diameter is about 35 mm. As for the medium size, the length from the tip 11 to the base 8 of the tip projection 7 is about 15 mm, the diameter of the base 8 is about 14 mm, the thickness of the rear projection 9 is about 10 mm, Is formed in about 30 mm. As a small one, the length from the tip 11 to the base 8 of the tip projection 7 is about 10 mm, the diameter of the base 8 is about 10 mm, the thickness of the rear projection 9 is about 10 mm, and the diameter is about 25 mm. It is formed.

  When using this umbilical hernia treatment material 1, first, the umbilical cavity 13 of an infant or the like and the surface of the abdomen 15 at the periphery of the umbilical cavity 13 are cleaned, and then protruded from the open hole 5 of the umbilical ring in the fascia 3. The intestinal tract is placed in the patent hole 5 with a finger or the like, that is, pushed into the abdominal cavity.

  Next, when the umbilical hernia treatment material 1 is inserted into the umbilical fossa 13 from the distal projection 7, the distal end portion 11 of the distal projection 7 closes the umbilical ring patency hole 5, and from the umbilical ring patency hole 5. It becomes possible to prevent the intestinal tract from protruding. At this time, the posterior protrusion 9 is also inserted into the umbilical fossa 13, and the upper surface of the umbilical fossa 13 and the skin around the umbilical fossa 13 are in contact with the surface of the posterior protrusion 9. . If the adhesive tape 25 is applied from the back 23 side of the umbilical hernia treatment material 1 thus inserted into the umbilical fossa 13, it can be fixed to the umbilical fossa 13.

  The tip protrusion 7 inserted into the umbilical fossa 13 can maintain a state in which the patent hole 5 is closed while the intestinal tract is accommodated in the rectus abdominis muscle 4. Further, when the baby is aggravated and the abdominal pressure rises, the rear protrusion 9 receives the action of the abdominal pressure and cushions it, and the tip protrusion 7 enters the patent hole 5 and absorbs it. Since the patency hole 5 can be stably occluded and the sealed state of the intestinal tract can be suitably maintained without being expanded, umbilical hernia can be reliably treated.

  In FIG. 1 described above, the back surface 23 of the rear projection 9 is formed in an arc shape, and the adhesive tape 25 can be applied to the back surface 23 along the skin roundness of the abdomen 15 of the infant. It is possible to stabilize the pressing action on the tip projection 7 and to improve the compression fixation.

  FIG. 3 shows that the portion from the base of the tip projection 7 to the upper surface of the rear projection 9 is formed in an arcuate shape that draws a gentle round 29, and the compression action and the buffering action are further merged for convenience. Sometimes it can be used.

  FIG. 4 shows the tip 11 of the tip projection 7 having a planar shape. In this case, even when the patency hole 5 is large, the distal end portion 11 of the distal projection 7 can stably store the intestinal tract in the rectus abdominis muscle 4.

  5 and 6 are the ones in which the rear protrusions 9 are formed in multiple stages 31, and the buffering action can be performed stepwise and in a distributed manner, so that they can be used conveniently.

  The tip protrusion 7 described above has been described as having a smooth dome-shaped surface, but it is also possible to appropriately form a longitudinal groove, a lateral groove, a spiral groove, or the like on the surface.

In the above-described umbilical hernia treatment material 1, the tip protrusion 7 has a substantially conical dome and the rear protrusion 9 has a disk shape. However, the shape of the tip protrusion 7 has a substantially elliptical cone dome shape, and the rear protrusion 9 has a substantially circular shape. An elliptical disk shape can be used, or these can be combined.
7 is formed so that the long axis of the substantially elliptical cone dome shape of the tip protrusion 7 and the long axis of the substantially elliptical disk shape of the rear protrusion 9 are orthogonal to each other. The major axes of these two protrusions can be crossed at an appropriate angle, or both major axes can be aligned in the same direction. If the tip projection 7 and the rear projection 9 are selected, there is a case where the tip projection 7 and the rear projection 9 can be used without giving a sense of pressure depending on the shape of the infant's navel. If the rear projections 9 have different vertical and horizontal lengths, if they are used so as to be horizontally long, the infant's body movements may occur even when the infant is bent forward or starts to stand. May not interfere with, and may be effective.

  7, the tip projection 7 is formed in a substantially elliptical cone dome shape with a length from the tip 11 to the base 8 of 15 mm, a major axis of the base 8 of 20 mm, and a minor axis of about 15 mm. 9 is formed in a substantially elliptical disk shape having a thickness of 10 mm, a major axis of 43 mm, and a minor axis of about 32 mm. As a smaller one, the tip protrusion 7 has a length of 15 mm, the base 8 has a long axis of 14 mm and a short axis of about 10.5 mm, and the rear protrusion 9 has a thickness of 10 mm and a long axis. The minor axis is about 26 mm at 35 mm. As a smaller one, the tip protrusion 7 has a length of 10 mm, the base 8 has a major axis of 10 mm and a minor axis of about 7.5 mm, and the rear protrusion 9 has a thickness of 10 mm and a major axis of 29 mm. Thus, the minor axis may be formed to about 22 mm.

  8 is provided with a plurality of arc-shaped cutout portions 33 on the side portion 21 of the rear projection 9, which can provide a buffering action against the abdominal pressure as the rear projection, and an infant or the like may mistakenly. Even in the case of aspiration in the mouth, the presence of the notch 33 ensures that the airway is not blocked, thus increasing safety.

  The thing of FIG. 9 is provided with the several through-hole 35 which leads to the contact surface 17 from the back surface 23 of the back protrusion 9, and can be used like the above. Further, in the case shown in FIG. 10, a hole 35 penetrating from the rear projection 9 to the tip projection 7 is provided. In these cases, it is preferable to adjust the elasticity, hardness, etc. of the buffer elastic body appropriately so that the hardness and strength of the entire treatment material 1 are not lowered by providing the notch 33 and the hole 35.

  In addition to the above, the shape of the tip protrusion 7 can be a substantially rounded polygonal pyramid shape or a rounded elliptic frustum shape as long as it has a curved surface on the top or side surface. As long as 9 has an arcuate surface that protrudes laterally from the base 8 of the tip projection 7, it can also be formed in a substantially polygonal shape with rounded corners.

  This umbilical hernia treatment material 1 can be enclosed with an adhesive tape, disinfectant solution, sterilized absorbent cotton, etc. to form a umbilical hernia treatment kit, which can be used by mothers and medical professionals such as nurses. This is more convenient when used by a person.

On the other hand, the test piece of Sample 8 could not be firmly fixed with the adhesive tape, and the state where the patency of the umbilical ring was blocked could not be maintained after 3 days. Five days later, when the test piece was removed, a slight symptom changed due to skin irritation or the like was observed on the umbilical fossa in contact with the test piece or the skin around the umbilical fossa.

※圧縮応力：（Ｎ／１２ｍｍφ×５ｍｍ）

* Compressive stress: (N / 12mmφ × 5mm)

[Discussion]
Samples 1 to 5 have a compressive stress in the range of 8.5 to 38.0 N / 12 mmφ × 5 mm and show an appropriate compressive stress. It is as low as 0.0 N / 12 mmφ × 5 mm, and the sample 7 is not preferable because it is too high as 300 N / 12 mmφ × 5 mm.
Samples 1 to 5 are all good (◯) in compression force and skin irritation and show excellent results. On the other hand, Samples 6, 8, and 9 gave acceptable (◯) results in skin irritation, but were not (x) in the compression force test, which is not preferable. In Sample 7, a good (◯) result was obtained in the compression force test, but it was impossible (×) in the skin irritation test, which is not preferable.
The results obtained by the model test using the above samples 1 to 9 can be obtained in the same manner in the umbilical hernia treatment material of the present invention. When the umbilical hernia treatment material of the present invention is fixed to the umbilical fossa, It can be seen that an effective pressing action can be obtained without applying excessive pressure to the skin or giving any irritation.
Further, the therapeutic material test shows that the sample 10 has a good therapeutic effect, whereas the sample 8 does not have a sufficient therapeutic effect.
