Description

  The present invention relates to an enema container that has a small amount of residual liquid and can improve usability.

  An enema container has been proposed in which a nozzle is erected on the top of the trunk of a pentahedral pyramid (Patent Document 1).

  The trunk portion has left and right planar side surfaces, front and rear substantially triangular pinions, and a rectangular bottom surface. In addition, inverted Y-shaped folds are formed on the front and rear toe surfaces, respectively, and linear folds are formed on the bottom surface in the front-rear direction. Each fold can be folded in a valley fold. Therefore, in this enema container, when both sides are pressed with fingers, each toe and bottom are both folded inward, and the entire amount of the chemical inside can be discharged through the nozzle, and the pressing force on both sides Even if it is lost, it will not return to its original shape, and there is no risk of reverse suction of the medicinal solution injected into the anus.

JP-A-61-213060

  According to such a prior art, the body of the pentahedron pyramid cannot be folded correctly inward by simply applying a pressing force to the left and right side surfaces, and the front and rear pinches in the initial stage of the folding operation. It is necessary to push the surface and bottom lightly inward, and it is not easy to use, and the torso of the pyramid is difficult to fold into a perfect flat plate, and the remaining liquid amount tends to be excessive. was there.

  Therefore, in view of the problems of the prior art, an object of the present invention is to further reduce the amount of remaining liquid and realize good usability by dividing the body part into a laterally symmetrical side part and a bottom part. The object is to provide an enema container that can be used.

  In order to achieve this object, the structure of the present invention is formed by integrally forming a body portion having a substantially triangular shape in front view and a nozzle standing on the top portion of the body portion, and the body portion can be folded in a mountain fold. It is divided into a laterally symmetrical side part and a bottom part through a first symmetrical fold, and each side part includes a diagonally downward ridge part and front and rear slopes formed on both sides of the ridge part, The bottom folds up and down through a symmetrical second fold that can be folded into a valley fold, and the bottom is formed in a rectangular grounding portion that is long on the left and right sides, and before and after forming on the long side and short side of the grounding portion, respectively. The body includes a slope and left and right slopes, and the body supports the bottom and presses each side so that the lower side of each side is in close contact with the left half or the right half of the bottom. The gist of this is that it can be folded with one hand.

  The first fold hangs down from the base of the nozzle to the front and rear branching points of the body and diverges diagonally downward and back and forth via the joint between the lower end of each side and the left and right ends of the bottom. The second folds can each continue across each side and to the vicinity of each branch point.

  Moreover, you may bulge each side part symmetrically right and left.

  According to the configuration of the present invention, the body portion is divided into the left and right symmetrical side portions and the bottom portion through the first fold, and each side portion is divided into the upper and lower portions through the second fold. By folding the lower side of each side portion so as to be in close contact with the bottom portion, the entire amount of the chemical solution inside can be discharged from the nozzle. At this time, the upper side of each side portion is deformed in a direction intimately contacting each other. In addition, the torso can be easily folded by one action with one hand even when the patient himself uses it, and the operation of injecting a drug solution with substantially no residual liquid is possible. Therefore, extremely good usability can be realized. However, “closely” as used herein includes a case where they are close enough. In addition, it is also easy to discharge only a part of the amount of the internal chemical solution by pressing the body part in the front-rear direction with fingers and elastically deforming the body part.

  The first fold, which can be folded in a mountain fold, hangs down from the base of the nozzle to the front and rear branch points of the body and branches obliquely downward, thereby clearly separating the body into left and right sides and bottom can do. At this time, before and after the first fold before branching above the branch point and above the first fold after branching below the branch point, the slopes before or after belonging to the left and right sides The front or rear slope belonging to the bottom is formed below the first fold after branching below the branch point.

  The second fold that can be folded into the valley fold can be easily folded into a predetermined shape by crossing the left and right side portions together with the first fold. This is because each side part can be folded at an acute angle of about 90 ° or less than 90 ° through the second fold.

  For each side, the lower side of the second fold is set to be equivalent to 1/2 of the effective length of the bottom, so that the lower side of each side is on the left or right half of the bottom. Can be folded so as to be in close contact with each other, and the amount of residual liquid can be minimized. At this time, each side part is not restored to its original shape by folding at an acute angle through the second fold, and there is no possibility of reverse suction of the discharged chemical. However, the effective length here means the length along the curved surface formed by the side portion or the bottom portion, that is, the length when the side portion or the bottom portion of the curved surface is extended in a planar shape.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The enema container is formed by integrally molding a body portion 10 having a substantially triangular shape in front view and a nozzle 21 standing on the top of the body portion 10 (FIGS. 1 and 2). However, FIGS. 2A to 2C are a front view, a side view, and a bottom view, respectively.

  The body 10 and the nozzle 21 are made of a thermoplastic resin having appropriate elasticity, and are integrally formed in a hollow shape by, for example, blow molding (FIGS. 1 and 3). 3 (A) and 3 (B) are central longitudinal sectional views of FIGS. 2 (A) and 2 (B), respectively.

  The upper end of the nozzle 21 is rounded into a dome shape, and a nozzle hole 21a is opened. In addition, a flange 21b for limiting the insertion length of the nozzle 21 is formed in the lower portion of the nozzle 21.

  A detachable cap 22 is attached to the nozzle 21. An anti-slip knurl 22 a is formed at the lower outer periphery of the cap 22, and a spigot 22 b that fits the nozzle hole 21 a of the nozzle 21 is suspended from the inner top surface.

  The trunk | drum 10 is divided into the side parts 12 and 12 and the bottom part 13 which are left-right symmetric via the 1st folds 11 and 11 symmetrical with front and back (FIG. 1, FIG. 2). Further, the left and right side portions 12 and 12 are divided into upper and lower portions through second symmetrical folds 14 and 14, respectively. The first folds 11, 11 hang down from the base of the nozzle 21 to the branch point 11 a in front of or behind the body 10, branch off obliquely downward, and the left and right sides of the bottom 12 and the bottom 13 of each side 12. It continues to the front and rear through the joint with the tip. The second folds 14, 14 respectively cross the side portions 12 and continue to the vicinity of the branch points 11 a, 11 a before and after the first folds 11, 11.

  Each side portion 12 includes an obliquely downward ridge portion 12a, and front and rear slopes 12b and 12b formed on both sides of the ridge portion 12a via front and rear bending lines 12c and 12c (FIG. 2A). ), (B)). However, the ridge portion 12a and the slopes 12b and 12b are divided into upper and lower portions through a common second fold line 14, respectively. Further, the bottom portion 13 is formed with a rectangular frame-shaped grounding portion 13a that is long on the left and right at the center (FIGS. 2A and 2C), and bent lines 13d and 13d that are in contact with the long side of the grounding portion 13a. ..., front and rear slopes 13b and 13b and left and right slopes 13c and 13c are formed.

  The inside of the grounding part 13a is curved upward and is formed in a shallow concave shape (FIGS. 3A and 3B). Therefore, the enema container can be stably erected on an arbitrary plane such as a desk via the grounding portion 13a.

  The first fold 11 can be mountain-folded (solid line, two-dot chain line in FIG. 4A). Further, the second fold line 14 can be valley-folded (solid line, two-dot chain line in the same figure (B)), and the bending line 12c can be extended in a planar shape (solid line in the same figure (C), Two-dot chain line). However, FIGS. 4A to 4C are enlarged sectional operation diagrams corresponding to the Z1-Z1 line, the Z2-Z2 line in FIG. 2A, and the Z3-Z3 line in FIG. 2B, respectively. . Note that the first fold 11 after branching below the branch point 11a in FIG. 2A can also be folded in the same manner as the first fold 11 in FIG. 4A. Each bending line 13d of C) can be extended in the same manner as the bending line 12c of FIG.

  In such an enema container, the cap 22 is removed and the nozzle hole 21a is opened, the thumb and index finger are placed on the left and right side portions 12 and 12 (FIG. 5A), and the bottom portion 13 is supported by the other three fingers. In this way, holding the nozzle 21 upward with one hand, inserting the nozzle 21 into its own anus, pressing the side parts 12 and 12 with the thumb and index finger and folding the body part 10 to discharge the total amount of the internal chemicals (FIGS. 5B and 5C). The left and right side portions 12 and 12 are valley-folded via the second fold line 14 and the first folds 11 and 11 are arranged below the left half of the bottom portion 13 or the right half. This is because it is folded in close contact with the part. In addition, at this time, the upper side of each side part 12 deform | transforms in the direction which mutually contacts. However, the support form of the bottom portion 13 by three fingers other than the thumb and index finger may be mainly the middle finger as shown in FIGS. 5 (A) to 5 (C), and the three fingers as shown in FIGS. 6 (A) to (C). All of these may be used in parallel.

  The enema container holds the thumb and forefinger or middle finger on the branch points 11a and 11a before and after the first folds 11 and 11 (FIG. 7A), and presses the torso 10 in the front-rear direction to be elastic. By deforming, a part of the internal chemical solution may be discharged (FIGS. 7B and 7C). At this time, the body portion 10 can be easily restored to the original shape by removing the front and back pressing force.

Other embodiments

  The body portion 10 may bulge the left and right side portions 12 and 12 symmetrically left and right (FIG. 8). However, FIGS. 8A to 8D are a perspective view, a front view, a side view, and a bottom view, respectively.

  Each side portion 12 is set such that c> a≈b / 2 as an effective length a on the lower side of the second fold line 14, an effective length c on the upper side, and an effective length b in the left-right direction of the bottom portion 13. (FIG. 8B). Therefore, when the body 10 folds the side portions 12 and 12 through the first folds 11 and 11 and the second folds 14 and 14 (FIG. 9), the body 10 passes through the second folds 14 and 14. Since each side portion 12 is bent at an acute angle of less than 90 °, the original shape is not restored. However, FIGS. 9A to 9C are a front view, a side view, and a bottom view, respectively, in a state in which the body portion 10 is folded. 8 and 9 has an increased internal volume by expanding the side portions 12 and 12 and enlarging in the front-rear direction compared to the barrel portion 10 of FIGS. ing. However, in FIG. 8 and FIG. 9, it is good also as c <= a.

  The present invention can be suitably applied not only when the patient himself uses it but also when the caregiver uses it for a third party.
