Abstract
Description
図9において、200は駆動回路、201は電源供給器、210,220は連続/パルス駆動選択スイッチ、230は関数発生器、231,233は増幅器、240,250は定電流供給部、260は赤色半導体レーザ、270は緑色半導体レーザ、280a,280bは光ファイバ鍼、290は患部または経絡である。
連続/パルス駆動選択スイッチ210,220において制御信号212,222により連続モードまたはパルスモードを選択すると、関数発生器230や増幅器231,233,定電流供給部240,250の働きにより赤色半導体レーザ260,緑色半導体レーザ270が連続発振またはパルス発振しレーザ光を出射する。赤色半導体レーザ260,緑色半導体レーザ270が出射したレーザ光は光ファイバ鍼280a,280bを介して患部または経絡290を照射する。
患部の画像を撮影する画像撮影手段と、
この画像撮影手段が撮影した患部の画像を表示する画像表示手段とを備え、
画像撮影手段が撮影した患部に対し上記レーザ光を照射することを特徴とするものである。
実施の形態1.
図1はこの発明に係る痛み緩和装置の外観を示す図であり、図1(a),(b),(c)はそれぞれ正面図、側面図、背面図である。また図2はこの発明の実施の形態1による痛み緩和装置の構成を示すブロック図である。
の略。
(※2)CMOS……相補型金属酸化膜半導体。Complementary Metal Oxide Semiconductor[英]の略。
図3はこの発明の実施の形態1による痛み緩和装置の動作を示すフローチャートである。
図3において、操作部7の電源ボタンをONして電源を投入するとCPU6がメモリ8からプログラムを読み出し痛み緩和装置が起動する。
加えて、使用者が出射ボタン5をONしない限り半導体レーザ1からレーザ光が出射されないので、レーザ光の誤照射を抑制して失明事故などを防止でき、痛み緩和装置の安全性を高められる。
患部Sの画像を撮影する際に影が生じたり、治療を行う場所が暗かったりといったように、撮影に必要な光量が不足することも考えられるので以下のようにしても良い。
図4はこの発明の実施の形態2による痛み緩和装置の構成を示すブロック図である。
図1,図4において、12は患部Sを照明する撮影用光源、13は撮影用光源12を駆動する撮影用光源駆動回路である。撮影用光源12および撮影用光源駆動回路13から照明手段が構成されている。
図5はこの発明の実施の形態2による痛み緩和装置の動作を示すフローチャートである。
図5において、CPU6は図3の場合と同様にステップST4までの処理を実行すると、撮影用光源12の使用について使用者からの入力を待ち受ける(ステップST8)。
レーザ光の誤照射により失明事故などを引き起こす恐れもあるので、より安全性を向上させるために以下のようにしても良い。
図6はこの発明の実施の形態3による痛み緩和装置の構成を示すブロック図である。
図1,図6において、14は照射部10Aの周囲に設けられた1以上のタッチセンサであり、患部Sと接触するとセンサ信号を出力する。15はタッチセンサ14からのセンサ信号を処理してタッチセンサ14と患部Sとの接触を検出するセンサ信号処理回路である。
タッチセンサ14およびセンサ信号処理回路15からタッチセンサ手段が構成されている。
図7はこの発明の実施の形態3による痛み緩和装置の動作を示すフローチャートである。
図7において、図5の場合と同様にステップST1~ST4,ST8,ST9の処理を実行すると、CPU6はタッチセンサ14と患部Sとの接触をセンサ信号処理回路15により判断する(ステップST10)。センサ信号処理回路15から接触が検出されていない場合は(ステップST10でNo)照射部10Aが患部Sに接近していないものと判断し、誤照射を防ぐためCPU6はレーザ駆動回路2を起動せず半導体レーザ1からレーザ光を出射しないで待ち受け状態となる(ステップST10でNo~ステップST6)。
半導体レーザ1が出射したレーザ光を患部Sへ照射する際に次のようにしても良い。
図8はこの発明の実施の形態4による痛み緩和装置の構成を示すブロック図である。図1,図8において、16は負の屈折力を有する光拡散手段としての拡散レンズである。図8では、その光軸を含む任意の平面で切断した平凹レンズを拡散レンズ16として図示してある。
