Abstract

PROBLEM TO BE SOLVED: To surely and stably insert an injection needle by enabling an operator to easily recognize the part or form of a vein. SOLUTION: Light from a light source (1) with a specified wavelength is transmitted through a specified wavelength filter (2) for the light source and radiated on the spot, where a vein part (6) seems to exit, for example, on an upper arm part (5) together with light (3) from a light source for reference and the reflected light is visually observed through a specified wavelength filter (4). The latter filter (4) is held by a holding part (7).

Description

【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は、人体の皮下静脈の位置、形状および状態を検出する装置に関する。 The present invention relates to a position of body endermic vein, an apparatus for detecting the shape and condition.

【0002】 [0002]

【従来の技術】従来、人体静脈に注射もしくは血液採取の目的で注射針を穿刺する際、その施術者は目視で静脈位置を探している。 Conventionally, when the puncture needle for purposes of injection or blood collection to the human body vein, the practitioner is looking for a vein position visually. しかるに上腕部の皮下のような部位ではこの目的に適う形状や太さあるいは状態の静脈がはっきりと露出していなくて容易に探せないことがあり、 However the site such as subcutaneous upper arm portion may not easily find veins in shape and thickness, or a state that meets this purpose has not been exposed clearly,
この際は同上腕部をゴムバンド等で緊迫し一時的にうっ血させたり、吸引機器に挿入したりして静脈を浮き上がらせる等の手法で対処している。 This time is addressed by a technique such as that float the vein or insert the upper arm or by tense temporarily congestive a rubber band or the like, the suction device.

【0003】 [0003]

【発明が解決しようとする課題】上述した従来技術は、 [SUMMARY OF THE INVENTION] the above-mentioned conventional technique,
施術者には高度の経験と技量を必要とし、患者等被術者には場合により苦痛や不安を与えることが多く、また失敗により皮下出血等の実害を与えることもあった。 The practitioner and requires a high degree of experience and skill, often inflict pain and anxiety by the case, the patient, such as a subject, also was also to give the actual harm of subcutaneous bleeding, such as by the failure. また、単に静脈部を見出すだけでは不充分でより注射針を穿刺するのに状態の良い静脈部位を探し出すべき場合には何回かの試行を要する等の課題があった。 Also, just a problem such as requiring several times trials when to find a good vein sites state to puncture more needle is only insufficient finding vein portion. 本発明によればかかる場合に施術者は容易にしかるべき静脈の部位や形状あるいは状態を識別把握でき、確実で安定して注射針を穿刺することが可能となり、上述の課題を解決できる。 Practitioner may take in accordance with the present invention can be readily identified grasp portion and the shape or state of the appropriate vein, reliable and stable it is possible to puncture the injection needle, can solve the problems described above.

【0004】 [0004]

【課題を解決するための手段】本発明は、主に特定波長光源、特定波長以外の波長も発光する参考用可視光源および特定波長光を選択的に透過するフィルターで構成される。 The present invention SUMMARY OF] is composed mainly specific wavelength light source, a filter that selectively transmits reference for visible light and the specific wavelength light is also emit wavelengths other than the specific wavelength.

【0005】 [0005]

【作用】このように構成し、特定波長光源および上記参考用可視光源を、静脈に注射針を穿刺すべき被術者の皮下静脈の存在が推測あるいはほぼ認定できる部位およびその近傍に投射し、その反射光を上記特定波長光を透過するフィルターを透して目視観察する。 [Action] thus configured, by projecting a specific wavelength light source and the references for the visible light source, should be punctured the needle into a vein in the site and the vicinity thereof there can be inferred or certified substantially subcutaneous vein of a subject, and visually observing the reflected light it through a filter that transmits the specific wavelength light. この際特定波長とは静脈血の光吸収スペクトルに相当する略890ナノメートルであり、この結果皮下静脈に投射された光源中の上記波長近傍の光は他の波長の光より多く吸収され反射量が減じこれを上記フィルターを透して見ると皮下静脈の存在部位はより暗くなる。 In this case the specific wavelength is substantially 890 nanometers which corresponds to the light absorption spectrum of the venous blood, many other are absorbed reflection amount than the light of the wavelength light of the wavelength near the Results source projected subcutaneously vein It is the present site of subcutaneous veins when subtracting see this it through the filter becomes darker. この時フィルターの透過性能および特定波長光源と参考用可視光源の強度を適宜選定調節すると対象被術者の身体における静脈の相対位置が視認識別できる。 The time filter permeability and specific wavelength light source and the relative position of the veins in the body of the intensity of reference for the visible light source appropriately selected to adjust the object to be surgeon visible identification.

【実施例】以下、本発明を図1に示す実施例について説明する。 EXAMPLES Hereinafter, a description will be given of an embodiment illustrating the present invention in FIG. 同図において(1)は特定波長用光源、(2) In FIG. (1) a particular wavelength light source, (2)
は前記光源用特定波長フィルター、(3)は参考用光源および(4)は特定波長フィルターを示す。 Certain wavelength filter, for the light source (3) is a reference light source and (4) shows a specific wavelength filter. また説明の便宜上(5)に人体の上腕部(6)に静脈部および(7)にフィルターの保持部を示す。 Further illustrating the holding portion of the filter for convenience vein portion and a human body of the upper arm portion (5) (6) (7) Description.

【0007】今1例として、特定波長用光源(1)にこの波長光を含む白熱灯を用いこの光を(2)のフィルターに特定波長890ナノメートルの光を選択的によく透過させるものを、参考用光源(3)として別の白熱灯そして上記特定波長の透過効率がかなり高いフィルター(4)を用いるとき、特定波長用光源(1)より発生した光は(2)のフィルターで特定波長のみ選択的に透過して上腕部(6)に投射される。 [0007] As now one example, the one which selectively well transmits light of a specific wavelength 890 nm to filter the light using an incandescent lamp including the wavelength to the light source (1) for a specific wavelength (2) when another incandescent lamp as a reference light source (3) and the transmission efficiency of the specific wavelength using a considerably higher filter (4), the light generated from the light source (1) for a specific wavelength filter at a specific wavelength of (2) only selectively permeable to be projected to the upper arm (6). この時特定波長フィルターを通してこの反射光を目視すると、上腕部上の静脈部(6)は略この特定波長を吸収するためそれ以外の部位よりも反射率が低下し、より暗く見える。 When viewing the reflected light through a particular wavelength filter at this time, the vein portions of the upper arm (6) is substantially reflectance lower than the site of the other to absorb the particular wavelength appears darker. ここに参考用光源(3)もあわせて同上腕部に投射するとフィルター(4)は少量のこの光も透過させ前記の暗く見える静脈部の上腕部における相対的な位置が識別できる。 Now the projected reference light source (3) Same upper arm together also filters (4) can be the relative position identification in a small amount of the upper arm portion of the look dark vein portion of the light is also not transmit the. このためには上記各構成要素(1)から(4)の性能特性を調整しておくことが必要である。 For this purpose it is necessary to have to adjust the performance characteristics of the above components (1) (4). 特に両光源(1)および(3)の照度の相対的強さは対象の状態に対応して適宜調整(装置は図示しない)するとよい。 In particular the relative intensity of illumination of both light sources (1) and (3) is appropriately adjusted according to the condition of the subject (device not shown) Then good. なお、両フィルター(2)および(4)も相互の特性は識別性能に影響があり、予め調整しておく。 Note that both filters (2) and (4) the mutual characteristics affect the classification performance, is adjusted in advance. 上記構成要素(1)、 Said component (1),
(2)、(3)、(4)および(7)は一つの装置としてまとめ架台(図示しない)に設置したり、あるいはシステムとして連係させながら動作するように適宜分割して設置してもよい。 (2), (3), (4) and (7) may be installed by appropriately divided to operate while linking or installation, or as a system to collectively stand as one apparatus (not shown) . また、本装置を特定の目的に簡易的に用いる際は、両光源(1)と(3)は一つにまとめることも可能である。 Also, when using this device in a simple manner to a specific purpose, and both the light source (1) (3) can be combined into one. なお、フィルターの保持部(7)は施術者の観察便宜のために設けられフィルターを保持してメガネのように用いたり手で保持するために供せられる。 The holding of the filter (7) is subjected to a hand held or used as glasses holding the filter is provided for observation convenience of the practitioner.

【発明の効果】以上説明したように、本発明の静脈検出装置によれば人体静脈に注射針を穿刺する際従来の方法に比べて高度の経験や技量がなくても容易に静脈部位を目視識別できるようになる。 As described above, according to the present invention, visually easily venous site without a high degree of experience and skill than the conventional method when puncturing the injection needle to the body intravenously, according to the vein sensing device of the present invention It will be able to identify. このため、例えば上腕部のどの位置にどのような形状の静脈があるかが確実に目視判別でき最適な部位を特定できる。 Thus, for example, whether there is any shape vein in which position the upper arm portion can be reliably visually determine identifiable optimal site. 同時に穿刺の行為中も施術者は観察を継続できるので安全性、確実性は大いに高められる。 Safety Since simultaneously acts in puncture even practitioner can continue observation, certainty is greatly enhanced. 被施術も精神的に安心でき、緊張や苦痛から開放されより円滑な医療等が促進され得る。 The treatment can also be mentally safe, smooth medical treatment than is released from the tension and pain can be promoted. なお、 It should be noted that,
この際観察される静脈の形状によってはある程度静脈の状態(硬さ、老化等)も推定できることが期待され、注射針の種類や穿刺の適否判断の方法にも役立ち得る。 In this case some venous state depending on the shape of the vein being observed (hardness, aging, etc.) also are expected to be estimated, may also help in the process of the kind and puncture suitability judging needle.
