Description

本考案は採血、静脈注射、点滴等の血管注射を練習するため人体に装着して注射針を刺入する技術を取得するための装着型注射モデルに関する。   The present invention relates to a wearable injection model for acquiring a technique for inserting a needle into a human body and practicing blood vessel injection such as blood collection, intravenous injection, and drip.

従来から注射もしくは採血等の手技を修得するため手技練習モデルが用いられている。その手技練習モデルとして、例えば特許文献1(実公昭57−22195号公報)には「静脈を形成する管が配設された人体腕部模型と、模擬血液等の液体を蓄える貯液槽と、この貯液槽内の液体を、前記管を経て貯液層に循環させる循管路と、前記貯液槽の液体を前記管路に送り込む送液ポンプとを備えた静脈注射教習具」が開示されている。また、特許文献2(実開平5−27776号公報)には「人体の皮膚を模擬した軟質の薄皮状部材と、該薄皮状部材の一方の面に配設された皮下組織もしくは筋肉組織を模擬した軟質の肉厚部材とその下部の保護部材からなる帯状の装着型注射採血手技練習模型であって、前記肉厚部材中に血管を模擬した人体注射採血部模擬部を埋設すると共に、その両端部に人体または人体模型の所要個所に着脱自在に装着するための取付け部とを備えたことを特徴とする装着型注射採血手技練習模型」が、そして、特許文献3(実公平5−14293号公報)には「血管注射を練習するための器具であって、弾性体を素材とし、表層部内に複数の血管模倣弾性チューブが埋設された模倣上腕体と、血管模倣弾性チューブ内への注射針を刺入位置の正誤の判定表示部とを備え、前記模倣上腕体は、血管模倣弾性チューブに注射を刺入する位置を上面に示した刺入部と、前記刺入部に近接した位置で弾性チューブに刺入された注射針を感知する感知機構と、弾性チューブの下方に埋設され、チューブを突貫した注射針を受け止めるためのストップ板とを有し、前記判定表示部は、弾性チューブ内の注射針を感知機構が感知した時に点燈するランプを盤体に設けたことを特徴とする、血管注射針練習器。」が記載されている。
上記のように、従来の手技習得模型は、概ね肉質を模した合成ゴムの中にチューブ状の模擬血管を埋設し、これを針刺し防止用のトレイ状の容器に入れるか或いは保護部材に載せ、これらのトレイ状容器もしくは保護部材を人体又は人体モデルに装着するのであるが、保護部材としては実際には厚み約0.5mm程度のプラスチックシートを使用しており、従って、いずれの場合も硬く、合成ゴムの肉質を模した針刺部位が人体に近い柔らかさがあっても底が硬いものとなり、装着感、密着感に欠けるという欠点があった。
Conventionally, a technique practice model has been used to acquire techniques such as injection or blood collection. As the technique practice model, for example, in Patent Document 1 (Japanese Utility Model Publication No. 57-22195), “a human arm model in which a tube forming a vein is arranged, a liquid storage tank for storing liquid such as simulated blood, Disclosed is an intravenous learning tool comprising a circulation path for circulating the liquid in the liquid storage tank to the liquid storage layer through the pipe, and a liquid feed pump for feeding the liquid in the liquid storage tank to the pipe line. Has been. Patent Document 2 (Japanese Utility Model Laid-Open No. 5-27776) discloses “a soft thin skin member simulating human skin and a subcutaneous tissue or muscle tissue disposed on one surface of the thin skin member. A belt-like wearable blood sampling technique training model composed of a soft thick member and a protective member under the soft thick member, and a human injection blood sampling part simulating part simulating a blood vessel is embedded in the thick member, and both ends thereof "A wearable injection blood sampling technique practice model characterized by having a mounting part for detachably mounting on a required part of a human body or a human body model", and Patent Document 3 (Japanese Utility Model Publication No. 5-14293) Gazette) “A device for practicing vascular injection, which is made of an elastic body and has a surface layer portion in which a plurality of vascular mimetic elastic tubes are embedded, and an injection needle into the vascular mimetic elastic tube The correct insertion position The imitation upper arm was inserted into the elastic tube at a position close to the insertion portion, and a insertion portion showing the position where the injection is inserted into the blood vessel imitation elastic tube on the upper surface. A sensing mechanism for sensing the injection needle; and a stop plate embedded under the elastic tube for receiving the injection needle penetrating the tube. The determination display unit is configured to detect the injection needle in the elastic tube. "A blood vessel needle training device, characterized in that a lamp is provided on the board to turn on when it is sensed."
As described above, the conventional technique acquisition model embeds a tube-like simulated blood vessel in a synthetic rubber generally imitating the flesh and puts it in a tray-like container for preventing needle stick or put it on a protective member, Although these tray-shaped containers or protective members are mounted on a human body or a human body model, a plastic sheet having a thickness of about 0.5 mm is actually used as the protective member, and therefore, in either case, it is hard. Even if the needle stick part imitating the flesh of synthetic rubber has a softness close to that of the human body, the bottom is hard, and there is a drawback that it lacks a feeling of wearing and a feeling of adhesion.

更に、従来の注射モデルでは血管に模した合成ゴムよりなる合成ゴムチューブを肉質部に埋設しているので、肉質部を刺通した針が模擬血管を刺通するとき、その感触は異なる。ところが、解剖学上静脈には血管壁が無く、血管壁が存在するのは動脈で合成ゴムのチューブに針を刺すのは人体静脈への注射した感覚とは程遠く、従って、合成ゴムチューブが埋設されている肉質部よりなる注射モデルは静脈血管への注射モデルとは言い難い。しかも、チューブ自体の肉厚のためこれを埋設したモデル本体も厚くなる。
また、従来の練習モデルには所定部位への装着機能をもたないものがあり、このような練習モデルを使用するには手技を受ける者が練習モデルを保持することになるため、不自然な位置、姿勢で患者に注射角度や針の打ち方などを練習することとなり現実の実施場面からはほど遠く、患者への関心も減弱することになる。そして、従来の練習モデルは人体の特定部位の忠実な模型にまで仕上げる必要があるため、高価になるという欠点があった。
Furthermore, in the conventional injection model, since a synthetic rubber tube made of synthetic rubber imitating a blood vessel is embedded in the meat part, the feel is different when the needle that has penetrated the meat part pierces the simulated blood vessel. However, the anatomical vein has no blood vessel wall, and the blood vessel wall exists in the artery, and the needle inserted into the synthetic rubber tube is far from the sense of injection into the human vein, so the synthetic rubber tube is embedded. It is difficult to say that the injection model consisting of the fleshy part is a model of injection into a venous blood vessel. In addition, because of the thickness of the tube itself, the model body in which it is embedded also becomes thick.
In addition, some of the conventional practice models do not have a function to attach to a predetermined site. To use such a practice model, the person receiving the procedure will hold the practice model, which is unnatural. The patient will practice the injection angle and how to shoot the needle in the position and posture, which is far from the actual implementation scene, and the patient's interest will be reduced. In addition, the conventional practice model has a disadvantage that it is expensive because it needs to be finished to a faithful model of a specific part of the human body.

本考案者らはこれらの欠点を改良すべく種々検討した結果、本考案を完成したもので、本考案はより実感のある安価な装着型注射モデルを提供することを目的とする。 As a result of various studies to improve these drawbacks, the present inventors have completed the present invention, and the present invention aims to provide a more practical and inexpensive wearable injection model.

本考案の要旨は、人体の血管を模擬した細管状の内腔部を設けた皮下組織もしくは筋肉組織を模擬した軟質の肉厚部材と、その下面に線径が0.08〜0.12mmの金属平織又はプラスチック網及び台紙を順次貼着、積層したことを特徴とする装着型注射採血手技練習模型である。
そして、前記金属平織の目開きが100メッシュ程度で、織り厚が約0.2mm程度であることが好ましく、また、前記台紙面に該練習模型を人体又は人体模型の所要個所に着脱自在に装着するための取付け部材を設けることが好ましい。
The gist of the present invention is that a soft thick member simulating a subcutaneous tissue or a muscular tissue provided with a thin tubular lumen simulating a human blood vessel, and a wire diameter of 0.08 to 0.12 mm on its lower surface A wearable injection blood sampling technique practice model characterized by sequentially attaching and laminating a metal plain weave or plastic net and a mount.
It is preferable that the mesh of the metal plain weave is about 100 mesh and the weaving thickness is about 0.2 mm, and the practice model is detachably attached to the mount or a required part of the human model on the mount surface. It is preferable to provide an attachment member for this purpose.

本考案においては従来の弾性チューブ状の模擬血管を使用することなく、肉厚部材に直接細管状の内腔を設け、更に、装着者への針刺し貫通を防止するため金属平織り又はプラスチックネットを使用したので、全体として柔軟性に富み、装着者の人体に密着感が良好で、更に金属平織り又はプラスチックネットによって針刺し貫通を防止し、安全性をも確保することが出来る等の効果を奏するのである。   In the present invention, without using a conventional elastic tube-like simulated blood vessel, a thick tubular member is directly provided with a thin tubular lumen, and a metal plain weave or plastic net is used to prevent needle penetration into the wearer Therefore, it is rich in flexibility as a whole, has a good feeling of close contact with the wearer's human body, and has the effect of preventing needle penetration with a metal plain weave or plastic net and ensuring safety. .

本考案について詳細に説明する。
本考案における皮下組織若しくは筋肉組織を模擬した軟質の肉厚部材としては、人体の皮下組織若しくはか筋肉組織に注射針又は採血針を刺入するときの感触が得られるような適度に軟質で、所要の強度、耐久性、耐熱性、耐薬品性、安全性等を有するものであれば特に制限されない。例えばエチレン・プロピレン共重合体等のオレフィン系ゴム、低密度ポリエチレン、ブチルゴム、軟質ポリ塩化ビニル、アクリル酸エステルの共重合体等のアクリル系ゴム、ポリエステル系エラストマ−、ポリエステルポリウレタン、ポリウレタン、シリコ−ンゴムなどの合成ゴム類や軟質合成樹脂類等の合成ゴム類、軟質合成樹脂類のほか、それらの発泡体、例えばポリウレタンフォ−ムなどが使用される。
The present invention will be described in detail.
As a soft thick member simulating the subcutaneous tissue or muscle tissue in the present invention, it is moderately soft so that the touch when inserting an injection needle or blood sampling needle into the subcutaneous tissue or muscle tissue of the human body is obtained, There is no particular limitation as long as it has the required strength, durability, heat resistance, chemical resistance, safety, and the like. For example, olefin rubber such as ethylene / propylene copolymer, low density polyethylene, butyl rubber, soft polyvinyl chloride, acrylic rubber such as acrylate copolymer, polyester elastomer, polyester polyurethane, polyurethane, silicone rubber In addition to synthetic rubbers such as the above, synthetic rubbers such as soft synthetic resins, and soft synthetic resins, foams thereof such as polyurethane foam are used.

そして、肉厚部の全体の厚さとしては約8mm程度である。この肉厚部の内部に模擬血管に相当する細管状の内腔(以下、これを模擬血管腔という場合がある。)を設ける。この模擬血管腔の径としては静脈に相当する径が好ましく、約4mm程度であり、従って、表面まで約2mm程度の肉厚が再現できる。模擬血管腔部の形成方法としては肉厚部材を金型で成型する際、金属の棒を肉厚部成型内に挿入し、ゴム状合成樹脂を成型する。ゴム状合成樹脂の硬化後、金属棒を引き抜くことによってトンネル状の模擬血管腔が形成される。模擬血管腔の本数は特に制限されること無く、1本若しくは数本設けてもよく、その形状は直線状であっても或いは曲線状であっても良い。
本考案では従来品のようなプラスチックチューブ壁による模擬血管壁が無い分肉厚部表面に近く模擬血管腔を成型することが出来、模擬肉質部全体を薄くすることが可能となると共に、注射針を刺通する際の感覚は従来品に比して実体に近いものとすることが出来た。
模擬血管腔の端部には必要に応じてポリエチレンなどの合成樹脂管を肉厚部から管を突設させておくと肉厚部材の外部より模擬血管腔に模擬血液を循環させるに好適である。
The total thickness of the thick portion is about 8 mm. A thin tubular lumen corresponding to a simulated blood vessel (hereinafter, this may be referred to as a simulated blood vessel cavity) is provided inside the thick portion. The diameter of the simulated blood vessel cavity is preferably a diameter corresponding to a vein, and is about 4 mm. Therefore, a thickness of about 2 mm can be reproduced up to the surface. As a method for forming the simulated blood vessel cavity, when a thick member is molded with a mold, a metal rod is inserted into the thick portion molding, and a rubber-like synthetic resin is molded. After the rubber-like synthetic resin is cured, a tunnel-like simulated blood vessel cavity is formed by pulling out the metal rod. The number of simulated blood vessel cavities is not particularly limited, and one or several simulated blood vessel cavities may be provided, and the shape thereof may be linear or curved.
In the present invention, the simulated blood vessel cavity can be molded close to the surface of the thick wall portion where there is no simulated blood vessel wall by the plastic tube wall as in the conventional product, and the entire simulated meat quality portion can be made thin, and the injection needle The sensation when piercing the can was made closer to the substance compared to the conventional product.
If necessary, a synthetic resin tube made of polyethylene or the like is projected from the thick part to the end of the simulated blood vessel cavity so that the simulated blood can be circulated from the outside of the thick member to the simulated blood vessel cavity. .

本考案における肉厚部材よりなる注射モデルの大きさは注射、採血の対象となる人体部位、体型、体質、性種等に応じて選定できるが、本考案の装着型注射採用手技練習模型を人体あるいは人体模型の所要の各部位、例えば肩部、上腕部、大腿部などに適宜に装着できる充分な、また、個体差に係わらず使用しうる長さと幅を有するのが好ましく、また次に記載する取付け部の形式によっても変わりうるものである。 The size of the injection model consisting of thick members in the present invention can be selected according to the human body part, body shape, constitution, sex, etc. subject to injection and blood collection. Alternatively, it is preferable that it has a length and a width that can be appropriately attached to each required part of the human body model, such as the shoulder, upper arm, and thigh, and that can be used regardless of individual differences. It can also be changed depending on the type of mounting portion to be described.

本考案にかかる手技練習模型の取付け部は、本考案の人体注射採血部位模擬部の両端部それぞれに直接、接着、縫合等により固着することもでき、また人体注射採血部位模擬部に、接着、縫合等により固着したテ−プ、ベルト等の先端部に固定手段を固着した構成とすることもできる。さらに取付け部を肩パット形式とすることによって上腕部から肩部にかけてしっかり装着することができる。
取付け部に使用する材料としては、テ−プ状接合材(例えばマジックテ−プ)、フックなどが挙げられる。本考案においては、上記人体注射採血部位模擬部を所望の部位に適用しうるよう、また個体差等にも充分対処できるように、例えばテ−プ状接合材の一方の固定手段を他方より幅広とし、固定位置を適宜に調節可能とすることが好ましい。
The attachment part of the technique practice model according to the present invention can be directly adhered to both ends of the human injection blood sampling site simulation part of the present invention by bonding, suturing, etc. It is also possible to adopt a configuration in which a fixing means is fixed to the tip portion of a tape, belt or the like fixed by sewing or the like. Furthermore, it can be firmly attached from the upper arm part to the shoulder part by making the attachment part into a shoulder pad type.
Examples of the material used for the attachment portion include a tape-shaped bonding material (for example, magic tape), a hook, and the like. In the present invention, for example, one fixing means of the tape-like bonding material is wider than the other so that the human body injection blood sampling site simulation part can be applied to a desired site and can sufficiently cope with individual differences. It is preferable that the fixing position can be adjusted appropriately.

本考案に係る装着型注射採血手技練習模型においては肉厚部の下面に針刺し防止のため金属でありながら柔軟性のある金属平織又はプラスチック網を選択した。従来品の装着型注射採血手技練習模型では針刺し貫通を防止するため硬いプラスチックのトレイ、プラスチックシート若しくは金属シートが使用されており、針刺部位が人体に近い柔らかさがあってもその下面が硬いものとなり、装着感、密着感が無いものとなっている。
本願考案では金属平織又はプラスチック網を使用したことによって柔軟性を保持することが出来た。使用する金属平織又はプラスチック網としては0.08〜0.12mm線径の銅線織物で目開き100メッシュ程度で注射針は貫通することはなく、針刺し貫通防止目的は十分達せられる。平織物としては厚み0.2mmで金属の板にない柔軟性がある。この金属メッシュを肉厚部材の下面に貼着することにより該練習模型の柔らかさが維持できる。またプラスチック網の場合も同様の網目で針刺し貫通防止目的は十分達せられるが、金属平織若しくはプラスチック網の下面に台紙が存在するので針刺し貫通の防止はより確実になる。
In the wearable injection blood sampling technique practice model according to the present invention, a metal plain weave or plastic net that is flexible while being metal was selected on the lower surface of the thick part to prevent needle stick. The conventional wearable injection blood sampling technique practice model uses a hard plastic tray, plastic sheet, or metal sheet to prevent needle stick penetration, and even if the needle stick part is soft like a human body, its lower surface is hard It becomes a thing, and there is no feeling of wearing and a feeling of adhesion.
In the present invention, it was possible to maintain flexibility by using a metal plain weave or a plastic net. The metal plain weave or plastic mesh used is a copper wire woven fabric with a wire diameter of 0.08 to 0.12 mm and has an opening of about 100 mesh so that the injection needle does not penetrate, and the purpose of preventing needle penetration is sufficiently achieved. As a plain woven fabric, it has a thickness of 0.2 mm and has flexibility not found in metal plates. The softness of the practice model can be maintained by sticking this metal mesh to the lower surface of the thick member. In the case of a plastic net, the purpose of preventing needle penetration is sufficiently achieved with the same mesh. However, since a base is present on the lower surface of the metal plain weave or plastic net, prevention of needle penetration is more reliable.

次に本考案に係る装着型注射採血手技練習模型として図面を以て更に具体的に説明する。
図1は本考案に係る手技練習模型の側面図であり、図2はその平面図である。図において、約8mmの肉厚部1の下面に金属平織2を貼着し、更にその下面に台紙3を貼着、積層する。肉厚部1の内部には模擬血管腔4が設けてある。模擬血管腔4の端部には必要に応じてシリコーンチューブ、ポリエチレンチューブ又は塩ビチューブなどのプラスチックチューブ5を突設しておいても良い。図3は当該模型を人体前腕に装着した場合の説明図であり取付け部6によって取り付ける。
Next, a wearable injection blood sampling technique practice model according to the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a side view of a technique practice model according to the present invention, and FIG. 2 is a plan view thereof. In the figure, a metal plain weave 2 is attached to the lower surface of the thick portion 1 having a thickness of about 8 mm, and a backing sheet 3 is further attached to the lower surface thereof and laminated. A simulated blood vessel cavity 4 is provided inside the thick portion 1. A plastic tube 5 such as a silicone tube, a polyethylene tube, or a polyvinyl chloride tube may be projected from the end of the simulated blood vessel cavity 4 as necessary. FIG. 3 is an explanatory view when the model is attached to the human forearm, and is attached by the attachment portion 6.

本考案に係る装着型注射採血手技練習模型は柔軟性に富み、人体又は人体模型に装着した場合、密着感があり、該模型を使用することによって実態に極めて近い感覚を得ることが出来るので、産業上利用可能性は高い。   The wearable injection blood sampling technique practice model according to the present invention is rich in flexibility, and when attached to a human body or a human body model, there is a feeling of adhesion, and by using the model, a feeling very close to the actual situation can be obtained, Industrial applicability is high.
