Description

本考案は、座薬を肛門内の所定位置に安定的に挿入できる座薬挿入器に関する。 The present invention relates to a suppository inserter capable of stably inserting a suppository into a predetermined position in the anus.

プランジャーで筒状体の先端に保持した座薬を肛門に挿入する技術は、特開平５−２６１１５８号公報（特許文献１）、特開平５−２６１１５９号公報（特許文献２）、特開２０００−１５７６３８号公報（特許文献３）が提案されている。特許文献１、２に開示された技術は座薬挿入時の筒状体の肛門挿入位置決め端を設けるのみで抜け止め手段がないため、プランジャー押し出し時に筒状体の位置決め端がずれ易いことと、筒状体の内周全長に渡りプランジャーの外周を案内することでプランジャーの動きが挿入時の指の挟持状態によって不必要に滑り難くなること、また、特許文献３に開示された技術は、注入器本体の筒体の先端に肛門当部を設けたもので座薬を肛門内部まで安定的に挿入できないことなどの欠点を内在していた。
特開平５−２６１１５８号公報特開平５−２６１１５９号公報特開２０００−１５７６３８号公報 Techniques for inserting a suppository held at the tip of a cylindrical body with a plunger into the anus are disclosed in Japanese Patent Laid-Open Nos. 5-261158 (Patent Document 1), 5-261159 (Patent Document 2), and 2000-. Japanese Patent No. 157638 (Patent Document 3) has been proposed. Since the techniques disclosed in Patent Documents 1 and 2 simply provide the anus insertion positioning end of the cylindrical body at the time of suppository insertion, and there is no retaining means, the positioning end of the cylindrical body tends to shift when the plunger is pushed out, By guiding the outer circumference of the plunger over the entire inner circumference of the cylindrical body, the movement of the plunger becomes difficult to slip unnecessarily depending on the clamping state of the finger during insertion, and the technique disclosed in Patent Document 3 is In addition, since the anus contact portion is provided at the tip of the cylindrical body of the injector main body, there are inherent disadvantages such that the suppository cannot be stably inserted into the anus.

本考案は、筒状体が肛門内の所定位置に挿入されるとともに、抜け止めされて安定的に位置決めされ、しかも、筒状体の肛門内への挿入時には、プランジャーが容易に摺動できず、所定位置に挿入後、プランジャーのみが滑らかに摺動して座薬を挿入できる座薬挿入器を提供する。 In the present invention, the cylindrical body is inserted into a predetermined position in the anus, is prevented from coming off and is stably positioned, and the plunger can easily slide when the cylindrical body is inserted into the anus. In addition, the present invention provides a suppository inserter capable of inserting a suppository by smoothly sliding only a plunger after being inserted into a predetermined position.

本考案の座薬挿入器は、筒状体にプランジャーが下端の押し部を介して摺動自在に挿入され、該筒状体の先端部から所要寸法後退した外周に挿入位置決め突部が周設されて成り、筒状体の先端部に座薬が保持されて使用される座薬挿入器において、
筒状体は、前記挿入位置決め突部より前方にその先端から滑らかに連続するテーパ面を形成した抜け止め突部が周設されて成り、
プランジャーは、その長手方向中間部に前記筒状体に嵌入する膨径部が配設され、該膨径部の前後の棒状体の外周と筒状体の内周間に変形空間が形成されて成る。 In the suppository inserter of the present invention, a plunger is slidably inserted into a cylindrical body via a pushing portion at the lower end, and an insertion positioning projection is provided around the outer periphery of the cylindrical body that is retracted by a required dimension. In the suppository inserter that is used, with the suppository being held at the tip of the cylindrical body,
The cylindrical body is formed by surrounding a protrusion protrusion that forms a taper surface that is smoothly continuous from the tip of the insertion positioning protrusion in front of the insertion positioning protrusion,
The plunger is provided with an enlarged diameter portion that fits into the cylindrical body at a longitudinal intermediate portion thereof, and a deformation space is formed between the outer periphery of the rod-like body before and after the expanded diameter portion and the inner periphery of the cylindrical body. It consists of

本考案の座薬挿入器によれば、プランジャーは筒状体挿入時に変形空間の変形によって摺動が阻止されるから、座薬は筒状体の挿入位置決め突部が肛門に当接するまで押し出されることがなく、常に一定深さの肛門内に挿入され、しかも、筒状体は抜け止め突部によって挿入状態が保持されるから、座薬は不十分な位置で肛門外に融出されることなく、その効能が安定的に確保される効果がある。 According to the suppository inserter of the present invention, since the plunger is prevented from sliding by deformation of the deformation space when the cylindrical body is inserted, the suppository is pushed out until the insertion positioning projection of the cylindrical body comes into contact with the anus. The tube is always inserted into the anus at a certain depth, and the cylindrical body is kept inserted by the retaining projection, so that the suppository is not melted out of the anus at an insufficient position. There is an effect that the efficacy is stably secured.

筒状体の先端からテーパ面を形成する抜け止め突部は、その先端が滑らかに該テーパ面に連続する形状が肛門内挿入に最良であり、また、プランジャーに配設される膨径部は一体構造のものから、着脱自在に嵌着又は螺着されるものなどである。 The retaining protrusion that forms a tapered surface from the distal end of the cylindrical body is best for insertion into the anus with its distal end smoothly continuing to the tapered surface, and the expanded diameter portion disposed on the plunger Is one having a monolithic structure and is detachably fitted or screwed.

本考案の座薬挿入器Ａを実施例により説明すると、筒状体であるシリンダー１はその先端を丸めて後方へ末広がり状のテーパ面２が形成され、その後端にシリンダー１の外周より僅かに突出する抜け止め突部３が配設され、その後方所要位置（先端から略23mm）には同様にシリンダー１の外周より所要に突出する挿入位置決め突部４が配設されて成る。
また、シリンダー１に挿入されるプランジャー５はシリンダー１の内径より僅かに小径の棒状体６の後端にＴ字状に押し部としての押し棒７を一体に成形し、棒状体６の長手方向中間部にその外径をシリンダー１の内径に摺動自在に内嵌する膨径部８を所要長さ分形成して成る。
シリンダー１にプランジャー５を膨径部８において摺動自在に嵌入したとき、プランジャー５の棒状体６の外径とシリンダー１の内径間に変形空間９が形成される。 The suppository inserter A according to the present invention will be described with reference to an embodiment. A cylinder 1 which is a cylindrical body is rounded at its tip to form a taper surface 2 which is widened toward the rear, and slightly protrudes from the outer periphery of the cylinder 1 at its rear end. A retaining protrusion 3 is provided, and an insertion positioning protrusion 4 that protrudes from the outer periphery of the cylinder 1 is similarly disposed at a required rear position (approximately 23 mm from the tip).
The plunger 5 inserted into the cylinder 1 is integrally formed with a push rod 7 as a pushing portion in a T-shape at the rear end of the rod-like body 6 having a diameter slightly smaller than the inner diameter of the cylinder 1. A swelled diameter portion 8 is formed in the middle portion in the direction by the required length so that the outer diameter of the cylinder 1 is slidably fitted into the inner diameter of the cylinder 1.
When the plunger 5 is slidably fitted into the cylinder 1 at the expanded diameter portion 8, a deformation space 9 is formed between the outer diameter of the rod-like body 6 of the plunger 5 and the inner diameter of the cylinder 1.

このようにして成る座薬挿入器Ａは、シリンダー１の先端部の内径に座薬１０が保持され、図２に示すように、プランジャー５の膨径部８より先方のシリンダー１の外周が指で挟持されるから変形空間９の変形によってプランジャー５の動きが阻止され、挿入位置決め突部４が図２の仮想線で示すように、肛門１１に当接されるまで挿入され、当接状態で変形空間９の変形が解放され、プランジャー５が押し棒７によって押し込まれると座薬１０は肛門内の所定位置に挿入される。
前記したようにシリンダー１の挿入位置決め突部４が肛門１１に当接された状態で抜け止め突部３は肛門内に係着されるから、常に肛門内の所定位置に座薬１０が挿入され、不十分な位置で座薬１０を肛門外に融出させることなく、座薬１０の効能が安定的に確保される。 In the suppository inserter A constructed as described above, the suppository 10 is held on the inner diameter of the tip of the cylinder 1, and the outer periphery of the cylinder 1 ahead of the expanded diameter portion 8 of the plunger 5 is a finger as shown in FIG. The movement of the plunger 5 is prevented by the deformation of the deformation space 9 since it is held, and the insertion positioning protrusion 4 is inserted until it comes into contact with the anus 11 as shown by the phantom line in FIG. When the deformation of the deformation space 9 is released and the plunger 5 is pushed by the push rod 7, the suppository 10 is inserted into a predetermined position in the anus.
As described above, since the retaining projection 3 is engaged in the anus while the insertion positioning projection 4 of the cylinder 1 is in contact with the anus 11, the suppository 10 is always inserted into a predetermined position in the anus, The efficacy of the suppository 10 is stably ensured without causing the suppository 10 to melt out of the anus at an insufficient position.

本考案の座薬挿入器は、病院などの医療現場では元より個人的にも簡便に且つ安定的に座薬の効能を確保できるから、大いにその需要が期待できる。 Since the suppository inserter of the present invention can secure the efficacy of the suppository easily and stably personally at the medical site such as a hospital, the demand can be expected greatly.
