Description
本発明は、直接手を触れることなくソフトコンタクトレンズを着脱するコンタクトレンズ着脱器具に関する。 The present invention relates to a contact lens attaching / detaching device for attaching / detaching a soft contact lens without directly touching the hand.
ソフトコンタクトレンズを取り外す場合、指先でレンズを挟み取る必要があるため、爪などで眼球を傷付けてしまう場合がある。また、直接眼球に指が触れることもあるため、外出先などでやむを得ず汚れた手でレンズの取り外しを行ってしまうと、雑菌などが混入して目の病気などを発症してしまう場合もある。 When removing the soft contact lens, it is necessary to pinch the lens with a fingertip, so the eye may be scratched with a nail or the like. In addition, since a finger may directly touch the eyeball, if the lens is removed with unavoidably dirty hands when going out and the like, various bacteria may be mixed to cause eye diseases and the like.
上記のような問題に関して、例えば特許文献１に示す技術が開示されている。特許文献１に示す技術は、シリコンゴム製の吸盤部１と、Ｌ字形の頸部２１を持つ合成樹脂製の操作部２とから成り、吸盤部１の周面１１の下方の変形部１２は、他の部分に比べて薄く成形され、薄く成形された変形部１２は、吸着面１３とソフトレンズ３の間の空間の気圧が下がるにつれ、ソフトレンズ３の周面を他の周面部分より引きつけ、その結果、吸盤部１の変形部１２は、他の周面部分に比べてより大きく変形し、ソフトレンズ３の周面の下部３１をめくり上げ、レンズを取り外しやすくするものである。 With regard to the problems as described above, for example, the technology shown in Patent Document 1 is disclosed. The technique shown in Patent Document 1 includes a suction cup portion 1 made of silicone rubber and an operation portion 2 made of synthetic resin having an L-shaped neck 21, and the deformation portion 12 below the circumferential surface 11 of the suction cup portion 1 is The deformation portion 12 which is thinly formed as compared with the other portions, and which is thinly formed has a circumferential surface of the soft lens 3 as compared with the other circumferential surface portion as the pressure of the space between the suction surface 13 and the soft lens 3 decreases. As a result, the deformation portion 12 of the suction cup portion 1 is deformed to a larger extent than the other peripheral surface portion, and the lower portion 31 of the peripheral surface of the soft lens 3 is flipped up to make the lens easy to remove.
しかしながら、特許文献１に示す技術は、周面の下方部分が変形することでソフトレンズをめくり上げる構成であるため、指を使った場合（親指と人差し指で抓み取る通常の取り外し方）と感覚が異なり、装着者が違和感を感じてしまう可能性がある。また、特許文献１に示す技術は吸盤部の形状が側面方向から見て三日月状となっているため、変形部を十分に変形させるためには強い吸引力が必要となり、力の制御が難しくなってしまう。 However, the technology shown in Patent Document 1 is configured to turn up the soft lens by deforming the lower part of the peripheral surface, so that the feeling when using a finger (the usual removal method of sucking with the thumb and forefinger) is felt There is a possibility that the wearer may feel discomfort. Further, in the technique shown in Patent Document 1, since the shape of the suction portion is a crescent shape when viewed from the side direction, a strong suction force is required to sufficiently deform the deformation portion, and it becomes difficult to control the force. It will
本発明は、釣鐘状の変形材料の開口部を変形させて、左右方向からソフトコンタクトレンズを挟み込みながら剥ぎ取ることで、指を使った場合の動作に近い感覚で違和感なくソフトコンタクトレンズの着脱を行うコンタクトレンズ着脱器具を提供する。 The present invention deforms the opening of the bell-shaped deformable material and peels off the soft contact lens while sandwiching the soft contact lens from the left and right direction, so that the soft contact lens can be attached and removed without discomfort in a sense similar to the operation when using a finger.

（本発明の第１の実施形態）
本実施形態に係るコンタクトレンズ着脱器具について、図１ないし図４を用いて説明する。本実施形態に係るコンタクトレンズ着脱器具はソフトコンタクトレンズ（以下、単にレンズという）の装着及び取り外しを行いものであり、特に、手でレンズを直接触ることなく、手で行う場合と同様の取り外し動作でレンズの取り外しを安全且つ簡単に行うことが可能である。
First Embodiment of the Present Invention
The contact lens attaching / detaching device according to the present embodiment will be described with reference to FIGS. 1 to 4. The contact lens attaching / detaching device according to the present embodiment is for attaching and detaching a soft contact lens (hereinafter simply referred to as a lens), and in particular, the same detaching operation as in the case where the lens is not in direct contact with hand by hand. It is possible to remove the lens safely and easily.
図１は、本実施形態に係るコンタクトレンズ着脱器具の全体斜視図、図２は、本実施形態に係るコンタクトレンズ着脱器具の平面図である。図２（Ａ）は、コンタクトレンズ着脱器具の上面図であり、図２（Ｂ）は、コンタクトレンズ着脱器具の側面図である。コンタクトレンズ着脱器具１は、レンズの凸面に当接させるための開口部２を先端部に有する釣鐘状の剥取部３と、連接管５を介して剥取部３に連接され、利用者の操作に応じて剥取部３における釣鐘内部の圧力を制御する本体部４とを備える。 FIG. 1 is an overall perspective view of a contact lens attaching and detaching device according to the present embodiment, and FIG. 2 is a plan view of the contact lens attaching and detaching device according to the present embodiment. FIG. 2A is a top view of the contact lens attaching and detaching device, and FIG. 2B is a side view of the contact lens attaching and detaching device. The contact lens attaching / detaching device 1 is connected to the bell-like peeling portion 3 having an opening 2 at the tip end for contacting the convex surface of the lens, and the peeling portion 3 via the connecting pipe 5 And a main body 4 for controlling the pressure inside the bell in the stripping section 3 according to the operation.
剥取部３における開口部２の縁部６は、少なくとも２箇所（例えば、開口部２の左右又は上下等）で他の部分に比べて相対的に薄く形成された変形部７ａ，７ｂを有しており、剥取部３における釣鐘の内部が負圧になった場合に、変形部７ａ，７ｂが釣鐘の内側方向に変形する構造となっている。 The edge 6 of the opening 2 in the peeling portion 3 has deformed portions 7a and 7b formed relatively thinly in at least two places (for example, right and left or upper and lower of the opening 2) as compared with other parts. When the inside of the bell in the peeling part 3 becomes negative pressure, the deformation parts 7a and 7b are deformed in the inward direction of the bell.
本体部４は、剥取部３と連接管５で連接され変形材料（例えば、プラスチック等）で形成された吸引部８と、吸引部８の両側面を対向して固定する挟持部９ａ，９ｂと、吸引部８の後端側に挟持部９ａ，９ｂの開閉動作の軸となる軸部１０と、挟持部９ａ，９ｂから軸部１０に延出し当該軸部１０を中心に回動動作が可能に設置されている接合板１１ａ，１１ｂとを備える。 The main body portion 4 is connected to the peeling portion 3 and the connecting pipe 5 and is a suction portion 8 formed of a deformable material (for example, plastic etc.) and holding portions 9a and 9b facing and fixing both side surfaces of the suction portion 8 The shaft portion 10 serving as the shaft of the opening and closing operation of the holding portions 9a and 9b extends from the holding portions 9a and 9b to the shaft portion 10 on the rear end side of the suction portion 8 It comprises bonding plates 11a and 11b which are installed as possible.
挟持部９ａ，９ｂは、接合板１１ａ，１１ｂが延出している箇所のさらに後端側に押圧部位１２ａ，１２ｂを有しており、この押圧部位１２ａ，１２ｂを相互に接近する方向（以下、内側方向という）に押圧することで、軸部１０を中心として挟持部９ａ，９ｂの先端部位１３ａ，１３ｂが相互に離隔する方向（以下、外側方向という）に可動する。先端部位１３ａ，１３ｂの可動に伴い、吸引部８が外側方向に引っ張られ、その張力により吸引部８が変形すると共に、吸引部８内が負圧の状態となる。 The pinching portions 9a and 9b have pressing portions 12a and 12b on the rear end side of the portions where the bonding plates 11a and 11b extend, and the pressing portions 12a and 12b are in the direction of approaching each other (hereinafter referred to as By pressing in the inward direction, the tip end portions 13a and 13b of the holding portions 9a and 9b move in the direction (hereinafter, referred to as the outward direction) with the shaft portion 10 as the center. With the movement of the distal end portions 13a and 13b, the suction portion 8 is pulled outward, the suction portion 8 is deformed by the tension, and the inside of the suction portion 8 is in a negative pressure state.
剥取部３の開口部２にレンズが密着している状態で上記のように吸引部８内が負圧になると、それに伴い剥取部４の釣鐘内部が負圧になる。その結果、釣鐘内部に掛かる圧力により剥取部３の変形部７ａ，７ｂが内側方向に変形してレンズを剥ぎ取る機能が実現される。 When the inside of the suction unit 8 becomes negative pressure as described above in a state where the lens is in close contact with the opening 2 of the peeling unit 3, the inside of the bell of the peeling unit 4 becomes negative pressure accordingly. As a result, the pressure applied to the inside of the bell deforms the deformation portions 7a and 7b of the peeling portion 3 in the inward direction to realize the function of peeling the lens.
利用者の動作に伴うコンタクトレンズ着脱器具１の機能について、図３及び図４を用いてさらに詳細に説明する。図３は、利用者が押圧部位１２ａ，１２ｂを押圧した場合のコンタクトレンズ着脱器具１の上面図及び側面図を示す。図４は、剥取部３における変形部７ａ，７ｂが変形する様子を示す図である。 The function of the contact lens attachment / detachment device 1 accompanying the operation of the user will be described in further detail using FIGS. 3 and 4. FIG. 3 shows a top view and a side view of the contact lens attachment / detachment device 1 when the user presses the pressing portions 12a and 12b. FIG. 4 is a view showing how the deformation parts 7a and 7b in the peeling part 3 are deformed.
図３に示すように、剥取部３の開口部２をレンズに密着させた状態で、利用者が指で押圧部位１２ａ，１２ｂを内側方向に押圧する動作（指で直接レンズを剥ぎ取る際のレンズを摘む動作に相当）を行うと、当該動作に伴って先端部位１３ａ，１３ｂが軸部１０を中心として回動するように外側方向に可動し、吸引部８が変形すると共に吸引部８の内部が負圧になる。この吸引部８の内部圧力により剥取部３の釣鐘内部の空気が連接管５を介して吸引部３に引き込まれ、釣鐘内部が負圧になる。 As shown in FIG. 3, in a state where the opening 2 of the peeling unit 3 is in close contact with the lens, the user presses the pressed portions 12 a and 12 b inward with the finger (when directly peeling the lens with the finger (Corresponding to the operation of pinching the lens), the tip portions 13a and 13b move outward so as to rotate about the shaft portion 10 in accordance with the operation, and the suction portion 8 is deformed and the suction portion 8 There is negative pressure inside. The air inside the bell of the stripping unit 3 is drawn into the suction unit 3 through the connecting pipe 5 by the internal pressure of the suction unit 8, and the pressure inside the bell becomes negative.
釣鐘内部が負圧になると、その圧力により図４に示すように、剥取部３の開口部２における変形部７ａ，７ｂが釣鐘の内部方向に変形する。この変形部７ａ，７ｂの動作が指の代わりとなり、左右方向からレンズを摘んで眼球から剥ぎ取る。レンズが取り外された後は、指の押圧力を弱めることで吸引部８の復元力により挟持部９ａ，９ｂが元の状態に戻る。吸引部８の復元に伴って剥取部３における釣鐘内部の圧力が大気圧となり、変形部７ａ，７ｂも復元され、剥取部３とレンズとが分離される。 When the inside of the bell becomes negative pressure, as shown in FIG. 4, the deformations 7a and 7b at the opening 2 of the peeling section 3 are deformed toward the inside of the bell by the pressure. The movement of the deformation portions 7a and 7b substitutes for the finger, and the lens is pinched from the left and right direction to be peeled off from the eye. After the lens is removed, the gripping force of the finger is weakened to restore the gripping portions 9a and 9b to the original state by the restoring force of the suction portion 8. The pressure inside the bell in the stripping unit 3 becomes atmospheric pressure along with the recovery of the suction unit 8, the deformations 7a and 7b are also restored, and the stripping unit 3 and the lens are separated.
このように、指で直接レンズを剥ぎ取る際のレンズを摘む動作と同様の動作を押圧部位１２ａ，１２ｂに対して行うことで、指で直接レンズを触ることなく、剥取部３の変形部７ａ，７ｂにより違和感なくレンズを取り外すことが可能となる。 As described above, by performing an operation similar to the operation of picking the lens when peeling off the lens directly with a finger on the pressing portions 12a and 12b, the deformation portion of the peeling unit 3 is not directly touched by the lens. The lenses 7a and 7b make it possible to remove the lens without discomfort.
なお、図４（Ａ）に示すように、剥取部３の開口部２における縁部６の外側形状を真円状とし、内側形状を楕円状とすることで、縁部６の左右２箇所に変形部７ａ，７ｂを形成するようにしてもよい。また、剥取部３の開口部２における縁部６の外側形状を楕円状とし、内側形状を真円状とすることで、縁部６の２箇所に変形部７ａ，７ｂを形成するようにしてもよい。この場合、外側形状の楕円における長径が垂直方向となるように（楕円が縦長となるように）構成することで縁部６の左右２箇所に変形部７ａ，７ｂを形成することが可能となる。 In addition, as shown to FIG. 4 (A), the outer shape of the edge 6 in the opening part 2 of the peeling part 3 is made into a perfect circle shape, and the inner shape is made into elliptical shape. The deformation portions 7a and 7b may be formed in Further, by forming the outer shape of the edge 6 in the opening 2 of the peeling portion 3 as an ellipse and making the inner shape as a true circle, the deformation portions 7a and 7b are formed at two places of the edge 6 May be In this case, the deformation portions 7a and 7b can be formed on the left and right two places of the edge portion 6 by configuring so that the major axis of the outer shape ellipse is in the vertical direction (ie, the ellipse is vertically elongated). .
また、押圧部位１２ａ，１２ｂへの指による押圧動作、及び、変形部７ａ，７ｂによるレンズを剥ぎ取る動作は、いずれもレンズ装着者の左右方向に対して加力、可動することが最も違和感なくレンズを取り外すことができるが、装着者の好みによっては、必ずしも左右方向に対しての押圧部位１２ａ，１２ｂへの加力、及び、変形部７ａ，７ｂの可動に限定される必要はない。 In addition, the pressing operation by the finger to the pressing portions 12a and 12b and the operation for peeling off the lens by the deforming portions 7a and 7b are all the most comfortable to move or move in the lateral direction of the lens wearer Although the lens can be removed, depending on the preference of the wearer, it is not necessarily limited to the force applied to the pressing portions 12a and 12b in the left-right direction and the movement of the deformation portions 7a and 7b.
（本発明の第２の実施形態）
本実施形態に係るコンタクトレンズ着脱器具について、図５及び図６を用いて説明する。本実施形態に係るコンタクトレンズ着脱器具は、剥取部３の前後方向の位置ずれを補正する手段を備えるものである。なお、本実施形態において、前記第１の実施形態と重複する説明は省略する。
Second Embodiment of the Present Invention
The contact lens attaching / detaching device according to the present embodiment will be described with reference to FIGS. 5 and 6. The contact lens attaching / detaching instrument according to the present embodiment is provided with means for correcting the positional deviation of the peeling section 3 in the front-rear direction. In the present embodiment, the description overlapping with the first embodiment is omitted.
図５は、剥取部３の前後方向の位置ずれを説明する図である。図５（Ａ）は通常時（レンズの着脱動作を行わない時）の状態を示し、図５（Ｂ）はレンズ着脱時の状態を示している。図からわかるように、押圧部位１２ａ，１２ｂが押圧されることで先端部位１３ａ，１３ｂが可動し、その結果、吸引部８の形状が変形し剥取部３の位置が本体部４の方向に後退する。つまり、剥取部３がレンズを摘み取る前にレンズから乖離してしまい、レンズを剥ぎ取ることができなくなる可能性がある。 FIG. 5 is a view for explaining the positional deviation of the stripping unit 3 in the front-rear direction. FIG. 5 (A) shows a normal state (when the lens attaching / detaching operation is not performed), and FIG. 5 (B) shows a lens attached / detached state. As can be seen from the figure, the tip portions 13a and 13b are moved by pressing the pressing portions 12a and 12b, and as a result, the shape of the suction portion 8 is deformed and the position of the peeling portion 3 is in the direction of the main portion 4. fall back. That is, there is a possibility that the peeling unit 3 may separate from the lens before picking it off and the lens may not be peeled off.
そこで、本実施形態においては、吸引部８が変形しても剥取部３の位置が本体部４の方向に後退しないように位置を補正する。図６は、本実施形態に係るコンタクトレンズ着脱器具における前後方向の位置を補正する場合の構成を示す図である。図６（Ａ）は吸引部８の形状を蛇腹状にした場合の構成を示しており、図６（Ｂ）は図６（Ａ）において連結棒を用いてより確実に補正する場合の構成を示しており、図６（Ｃ）は図６（Ａ）においてフックを用いてより確実に補正する場合の構成を示している。 So, in this embodiment, even if suction part 8 changes, a position is corrected so that a position of exfoliation part 3 may not retreat to a direction of body part 4. FIG. 6 is a view showing a configuration in the case of correcting the position in the front-rear direction in the contact lens attaching / detaching device according to the present embodiment. FIG. 6 (A) shows the configuration in the case where the shape of the suction portion 8 is made bellows-like, and FIG. 6 (B) shows the configuration in the case where correction is more reliably using the connecting rod in FIG. FIG. 6C shows a configuration in the case where correction is more reliably performed using hooks in FIG. 6A.
本実施形態においては、図６（Ａ）に示すように、吸引部８が外側方向及び内側方向に伸縮自在となるように形成された蛇腹状となるのが好ましい。そうすることで、押圧部位１２ａ，１２ｂへの押圧に伴って、吸引部８の後方側の面６１の伸縮率と前方側の面６２の伸縮率との差により、吸引部８が前方側の面を押し出されるように可動し、剥取部３の位置が後退するのを防止することが可能となる。 In the present embodiment, as shown in FIG. 6A, it is preferable that the suction portion 8 be in the form of a bellows formed so as to be stretchable in the outward direction and the inward direction. By doing so, the suction portion 8 is located on the front side due to the difference between the expansion ratio of the surface 61 on the rear side of the suction portion 8 and the expansion ratio of the surface 62 on the front side with the pressure on the pressing portions 12a and 12b. It is possible to move so as to push out the surface, and to prevent the position of the stripping unit 3 from being retracted.
また、より確実に位置補正を行う場合には、図６（Ｂ）や図６（Ｃ）に示すように、軸部１０と吸引部８の後方側の面６１との距離を一定に保持する。図６（Ｂ）では、軸部１０と面６１とを連結棒６３で接続して固定する。そうすることで、押圧部位１２ａ，１２ｂへの押圧があった場合であっても、面６１と軸部１０との距離が一定に保持される。そして、面６１が連結棒６３に支持されることで、蛇腹状の吸引部８が後退することを防止することができる。 Further, when performing position correction more reliably, as shown in FIG. 6 (B) and FIG. 6 (C), the distance between the shaft portion 10 and the rear surface 61 of the suction portion 8 is kept constant. . In FIG. 6B, the shaft portion 10 and the surface 61 are connected by the connecting rod 63 and fixed. By doing so, even when there is a pressure on the pressed portions 12a and 12b, the distance between the surface 61 and the shaft portion 10 is held constant. And by the surface 61 being supported by the connection rod 63, it can prevent that the bellows-like attraction | suction part 8 retreats.
図６（Ｃ）の場合も同様に、軸部１０と吸引部８の後方側の面６１との距離を一定に保持する。具体的には、面６１にフック６４を通すための孔が空いた突起部６５を設け、挟持部９ａ又は挟持部９ｂのいずれかにフック６４を固着する。フック６４は、軸部１０を中心として弧を描くように湾曲して配置されるように突起部６５の孔に挿通される。こうすることで、押圧部位１２ａ，１２ｂへの押圧があった場合であっても、フック６４の円弧で面６１が押し出されるように作用し、結果として蛇腹状の吸引部８が後退することを防止することができる。 Similarly, in the case of FIG. 6C, the distance between the shaft portion 10 and the rear surface 61 of the suction portion 8 is held constant. Specifically, a protrusion 65 having a hole for passing the hook 64 is provided in the surface 61, and the hook 64 is fixed to either the holding portion 9a or the holding portion 9b. The hooks 64 are inserted into the holes of the protrusions 65 so as to be curved and arranged so as to draw an arc around the shaft 10. By doing this, even when pressure is applied to the pressing portions 12a and 12b, the arc of the hook 64 acts to push out the surface 61, and as a result, the bellows-like suction portion 8 retreats. It can be prevented.
なお、吸引部８は必ずしも蛇腹状に形成される必要はないが、面６１を支持する力が面６２にそのまま伝わるように吸引部８の各部位の形状、材質、硬度（変形度）が調整されていることが望ましい。 The suction portion 8 is not necessarily formed in a bellows shape, but the shape, material, and hardness (deformation degree) of each portion of the suction portion 8 are adjusted so that the force supporting the surface 61 is transmitted to the surface 62 as it is. It is desirable that it is done.
また、使用者によっては、剥取部３が徐々に後退することで効果的に眼球からレンズを取り外せる場合もある。その場合には、連結棒６３やフック６４を設けずに、吸引部８の蛇腹の伸縮率で後退距離が調整されるようにしてもよい。 Further, depending on the user, the lens may be effectively removed from the eye by the gradual removal of the peeling section 3. In such a case, the retraction distance may be adjusted by the expansion and contraction rate of the bellows of the suction portion 8 without providing the connecting rod 63 and the hook 64.

本実施形態に係るコンタクトレンズ着脱器具について、図７を用いて説明する。本実施形態に係るコンタクトレンズ着脱器具は、剥取部３の開口部２の形状が、変形部７ａ，７ｂにおいて前方に突出しているものである。なお、本実施形態において、前記各実施形態と重複する説明は省略する。
Third Embodiment of the Present Invention
The contact lens attaching / detaching device according to the present embodiment will be described with reference to FIG. In the contact lens attaching / detaching instrument according to the present embodiment, the shape of the opening 2 of the peeling portion 3 projects forward in the deformation portions 7a and 7b. In the present embodiment, the description overlapping with each of the above embodiments is omitted.
図７は、本実施形態に係るコンタクトレンズ着脱器具における剥取部の構造を示す図である。図７（Ａ）は剥取部３の全体斜視図、図７（Ｂ）は剥取部３の上面図、図７（Ｃ）は剥取部３の側面図である。図７に示すように、剥取部３の開口部２の形状が全体的に湾曲しており、レンズの凸部と密着しやすい形状となっている。また、変形部７ａ，７ｂの箇所において前方向（レンズ着脱時における眼球側）への凸状体７１ａ，７１ｂが形成されており、この凸状体７１ａ，７１ｂによりレンズが摘みやすくなっている。すなわち、指の動作により近い状態を実現している。 FIG. 7 is a view showing the structure of the peeling portion in the contact lens attaching / detaching instrument according to the present embodiment. FIG. 7A is an overall perspective view of the peeling part 3, FIG. 7B is a top view of the peeling part 3, and FIG. 7C is a side view of the peeling part 3. As shown in FIG. 7, the shape of the opening 2 of the peeling portion 3 is curved as a whole, and is in a shape that can be easily in close contact with the convex portion of the lens. In addition, convex bodies 71a and 71b in the forward direction (eyeball side at the time of lens attachment and detachment) are formed at the locations of the deformed portions 7a and 7b, and the lenses are easily pinched by the convex bodies 71a and 71b. That is, the state closer to the movement of the finger is realized.
