Description

本発明は、外科手術ドリル用洗浄ツールの技術に関し、例えば、外科手術ドリルをウォッシャーディスインフェクターに連結する技術に関する。 The present invention relates to a technique for cleaning tools for surgical drills, for example, a technique for connecting a surgical drill to a washer-disinfector.

従来、一つの入水側ホース継手と洗浄器とを接続し、複数の排水側ホース継手と洗浄対象物とを接続する技術が知られていた（例えば、特許文献１参照）。特許文献１には、一つの入水側ホース継手から入水された洗浄液を複数の排水側ホース継手に排水することで、複数のホース継手に接続された複数の洗浄対象物の内腔部を同時に洗浄する技術が開示されている。 Conventionally, a technique of connecting one water inlet side hose joint and a washer and connecting a plurality of drain side hose joints and a cleaning object has been known (see, for example, Patent Document 1). According to Patent Document 1, by draining the cleaning liquid input from one water inlet side hose joint to a plurality of drain side hose joints, the lumens of a plurality of objects to be cleaned connected to the plurality of hose joints are simultaneously cleaned. The technology to be used is disclosed.

しかしながら、従来の技術は、入水側のホース継手と排水側の複数のホース継手が同一形状であるため、それぞれの位置毎に排水側ホース継手から排出される水量に差が生じやすく、洗浄対象物の取り付け位置によって洗浄度に差異が出てしまうという問題があった。 However, in the conventional technique, since the hose joint on the water inlet side and the hose joints on the drain side have the same shape, the amount of water discharged from the hose joint on the drain side tends to differ depending on each position, and the object to be cleaned There is a problem that the degree of cleaning differs depending on the mounting position of the hose.

上述の課題を解決するため、本願発明は、管状の洗浄対象（６）の内部の洗浄を支援するための洗浄ツール（４）を以下のように構成する。そして、その洗浄ツール（４）が、洗浄液を受ける入水側継手（１１）と、洗浄液を洗浄対象（６）に提供する洗浄液供給部と、その入水側継手（１１）と洗浄液供給部との間に配置され入水側継手（１１）を介して流れ込む洗浄液を受ける内部空間を有し、その内部空間を経由して洗浄液供給部に供給する分岐ホルダー（１０）とを具備するように構成する。 In order to solve the above-mentioned problems, the present invention comprises a cleaning tool (4) for supporting cleaning of the inside of the tubular cleaning object (6) as follows. Then, the cleaning tool (4) is between the water inlet side joint (11) that receives the cleaning liquid, the cleaning liquid supply unit that supplies the cleaning liquid to the cleaning target (6), and the water inlet side joint (11) and the cleaning liquid supply unit. It has an internal space for receiving the cleaning liquid flowing through the water inlet side joint (11), and is configured to include a branch holder (10) for supplying the cleaning liquid to the cleaning liquid supply unit via the internal space.

この構成において、入水側継手（１１）が、第１の管径の第１管部（１３）と、洗浄液の流れを基準に第１管部（１３）の後段に設けられた第２の管径の第２管部（１４）とを備えるようにする。また、洗浄液供給部が、洗浄液を分配するために複数の排水側継手（１２）を備えるようにする。ここにおいて、複数の排水側継手（１２）の各々は、第１の管径と異なる第３の管径の第３管部（１５）と、第３管部（１５）の前段に設けられた第４の管径の第４管部（１６）とを備えるものとする。 In this configuration, the water inlet side joint (11) is provided in the first pipe portion (13) having the first pipe diameter and in the second pipe after the first pipe portion (13) based on the flow of the cleaning liquid. It is provided with a second pipe portion (14) having a diameter. Further, the cleaning liquid supply unit is provided with a plurality of drain side joints (12) for distributing the cleaning liquid. Here, each of the plurality of drain side joints (12) is provided in a third pipe portion (15) having a third pipe diameter different from the first pipe diameter and in front of the third pipe portion (15). It shall be provided with a fourth pipe portion (16) having a fourth pipe diameter.

洗浄ツール（４）の入水側継手（１１）に対し、径の異なる排水側継手（１２）を構成することで、排水側の流量を所望の状態にすることができる。例えば、上述の洗浄ツール（４）において、複数の排水側継手（１２）の各々は、第１の管径よりも細い第３の管径の第３管部（１５）を備えることが好ましい。 By configuring the drainage side joints (12) having different diameters with respect to the water inlet side joints (11) of the cleaning tool (4), the flow rate on the drainage side can be set to a desired state. For example, in the cleaning tool (4) described above, it is preferable that each of the plurality of drain side joints (12) includes a third pipe portion (15) having a third pipe diameter smaller than the first pipe diameter.

第１の管径よりも細い第３の管径を構成することで、入力側の洗浄液の供給能力を排水側の排水能力よりも相対的に高くすることができる。 By configuring a third pipe diameter smaller than the first pipe diameter, the supply capacity of the cleaning liquid on the input side can be made relatively higher than the drainage capacity on the drain side.

さらに、上記の洗浄ツール（４）において、第１管部（１３）の断面積が、複数の排水側継手（１２）の各々の第３管部（１５）の断面積の和を超えるような構成であることが好ましい。
このような構成にすることによって、排水側に複数の継手が設けられた場合であっても、入力側の洗浄液の供給能力を排水側の排水能力よりも相対的に高くすることができる。 Further, in the above cleaning tool (4), the cross-sectional area of the first pipe portion (13) exceeds the sum of the cross-sectional areas of the third pipe portion (15) of each of the plurality of drainage side joints (12). The configuration is preferable.
With such a configuration, even when a plurality of joints are provided on the drainage side, the supply capacity of the cleaning liquid on the input side can be made relatively higher than the drainage capacity on the drainage side.

さらに、上記の洗浄ツール（４）において、第２管部（１４）が、第１の管径よりも大きい径で構成され、また、複数の排水側継手（１２）の各々の第４管部（１６）が、対応する第３管部（１５）の管径よりも大きい径で構成されることが好ましい。これによって、洗浄液の流れる速さを自動的に制御され、流速に起因する洗浄能力の差異をなくす、もしくは低減することができる。 Further, in the cleaning tool (4), the second pipe portion (14) is configured to have a diameter larger than the first pipe diameter, and the fourth pipe portion of each of the plurality of drain side joints (12). It is preferable that (16) has a diameter larger than the pipe diameter of the corresponding third pipe portion (15). As a result, the flow speed of the cleaning liquid is automatically controlled, and the difference in cleaning capacity due to the flow velocity can be eliminated or reduced.

さらに、上記の洗浄ツール（４）において、複数の排水側継手（１２）の各々の第３管部（１５）がそれぞれ同じ径であるような構成であることが好ましい。このような構成にすることで、各継手による洗浄能力の差異をなくすことができる。 Further, in the cleaning tool (4), it is preferable that the third pipe portion (15) of each of the plurality of drain side joints (12) has the same diameter. With such a configuration, it is possible to eliminate the difference in cleaning ability between the joints.

上述したように、本願発明の洗浄ツール（４）は、洗浄液を分配して複数の洗浄対象（６）の内部を一度に洗浄することができる。その洗浄ツール（４）を構成する際に、入水側継手（１１）からの洗浄液の供給能力を排水側継手（１２）からの洗浄液の排水能力よりも大きくなるようにすることによって、従来できなかった取り付け位置の違いによる洗浄度の差異をなくすことができるようになった。 As described above, the cleaning tool (4) of the present invention can distribute the cleaning liquid to clean the inside of a plurality of cleaning objects (6) at once. When constructing the cleaning tool (4), the capacity of supplying the cleaning liquid from the water inlet side joint (11) is made larger than the capacity of draining the cleaning liquid from the drain side joint (12), which cannot be conventionally performed. It has become possible to eliminate the difference in the degree of cleaning due to the difference in the mounting position.

なお、図１には、本願発明の理解を容易にするために、洗浄システム１において一つのアタッチメント６が洗浄ツール４に接続されている状態を例示している。後述するように、本実施形態の洗浄ツール４は、複数のアタッチメント６を一度に洗浄することができる。そのとき、洗浄ツール４に連結される複数のアタッチメント６が異なる形状の器具であっても、本実施形態に述べる洗浄ツール４を用いることで、それらの適切な洗浄を実現する。 Note that FIG. 1 illustrates a state in which one attachment 6 is connected to the cleaning tool 4 in the cleaning system 1 in order to facilitate understanding of the present invention. As will be described later, the cleaning tool 4 of the present embodiment can clean a plurality of attachments 6 at a time. At that time, even if the plurality of attachments 6 connected to the cleaning tool 4 are instruments having different shapes, appropriate cleaning of them can be realized by using the cleaning tool 4 described in the present embodiment.

ウォッシャーディスインフェクター２は手術器具、麻酔器具等の医療器具を洗浄・消毒するための箱型装置である。ウォッシャーディスインフェクター２は、備え付けられているドア（図示されず）を開閉することにより洗浄対象物をウォッシャーディスインフェクター２内の洗浄エリア（図示されず）に搬入、搬出することができる。その洗浄エリアの天井部および床下部または中間部には回転式の洗浄液散布器（図示されず）が備えられている。 The washer-disinfector 2 is a box-type device for cleaning and disinfecting medical instruments such as surgical instruments and anesthesia instruments. The washer-disinfector 2 can carry in and out the object to be cleaned into the cleaning area (not shown) in the washer-disinfector 2 by opening and closing the provided door (not shown). A rotary cleaning liquid sprayer (not shown) is provided on the ceiling and underfloor or intermediate portion of the cleaning area.

洗浄エリアには、洗浄液を供給するための配管（洗浄液供給口）や、その配管に接続可能なアクセサリーが設けられている。その洗浄エリアの配管あるいは配管に接続可能なアクセサリーには、ホース継手が備えられており、フレキシブルチューブを介して継手と洗浄対象物とを接続することで洗浄対象物内腔部に洗浄液が流される。ウォッシャーディスインフェクター２は運転プログラムに従い、洗浄対象物を自動で洗浄し、熱水消毒し、温風乾燥する。 The cleaning area is provided with a pipe for supplying the cleaning liquid (cleaning liquid supply port) and accessories that can be connected to the pipe. The pipes in the cleaning area or accessories that can be connected to the pipes are equipped with hose joints, and by connecting the joints to the object to be cleaned via a flexible tube, the cleaning liquid flows into the cavity of the object to be cleaned. .. The washer-disinfector 2 automatically cleans the object to be cleaned, disinfects it with hot water, and dries it with warm air according to the operation program.

本実施形態においては、チューブ３およびチューブ５がフレキシブルなシリコンチューブである場合を例示する。洗浄システムによる洗浄を行われる際は、チューブ内を洗浄液が通過する。 In this embodiment, the case where the tube 3 and the tube 5 are flexible silicon tubes will be illustrated. When cleaning is performed by the cleaning system, the cleaning liquid passes through the tube.

図２は、洗浄対象物であるアタッチメント６の構成を示す側面図である。上述したように、本実施形態において、洗浄ツール４に接続可能な器具であればアタッチメント６の形状に制限はない。以下では、本願発明の理解を容易にするために、一般的なアタッチメント６を例に、本実施形態の構成・動作の説明を行う。
洗浄システム１を用いてアタッチメント６を洗浄する場合、外側と内腔部との両方を洗浄しなければならない。アタッチメント６の外側表面はウォッシャーディスインフェクター２内の洗浄エリアに設置されている回転式洗浄液散布器により洗浄液を散布され、洗浄される。図２を参照すると、アタッチメント６にはモータ接続部７と先端部８が備えられている。内腔部を洗浄するために、モータ接続部７にチューブ５を介して洗浄ツール４が接続される。洗浄ツール４から放出された洗浄液は、アタッチメント６の内腔部を通り先端部８から排出される。これによってアタッチメント６の内腔部が洗浄される。 FIG. 2 is a side view showing the configuration of the attachment 6 which is an object to be cleaned. As described above, in the present embodiment, the shape of the attachment 6 is not limited as long as it is an instrument that can be connected to the cleaning tool 4. Hereinafter, in order to facilitate understanding of the present invention, the configuration and operation of the present embodiment will be described using a general attachment 6 as an example.
When cleaning the attachment 6 using the cleaning system 1, both the outside and the lumen must be cleaned. The outer surface of the attachment 6 is cleaned by spraying the cleaning liquid with a rotary cleaning liquid sprayer installed in the cleaning area in the washer-disinfector 2. Referring to FIG. 2, the attachment 6 is provided with a motor connection portion 7 and a tip portion 8. A cleaning tool 4 is connected to the motor connection 7 via a tube 5 to clean the lumen. The cleaning liquid discharged from the cleaning tool 4 passes through the lumen portion of the attachment 6 and is discharged from the tip portion 8. This cleans the lumen of the attachment 6.

図３は、洗浄ツール４の外観を示す側面図である。図３を参照すると、洗浄ツール４は分岐ホルダー１０と一つの入水側ホース継手１１と複数の同一形状の排水側ホース継手１２で構成される。入水側ホース継手１１はチューブ３を介してウォッシャーディスインフェクター２内の配管部ホース継手（図示されず）に接続され、複数の排水側ホース継手１２はチューブ５を介してアタッチメント６のモータ接続部７に接続される。 FIG. 3 is a side view showing the appearance of the cleaning tool 4. Referring to FIG. 3, the cleaning tool 4 is composed of a branch holder 10, one water inlet side hose joint 11, and a plurality of drain side hose joints 12 having the same shape. The water inlet side hose joint 11 is connected to the pipe portion hose joint (not shown) in the washer-disinfector 2 via the tube 3, and the plurality of drain side hose joints 12 are connected to the motor connection portion of the attachment 6 via the tube 5. Connected to 7.

図４は、洗浄ツールの内部構造を示す断面図である。図４の（ａ）は、洗浄ツール４を洗浄液の流路に沿って切断したときの断面を例示し、図４の（ｂ）は、入水側ホース継手１１と排水側ホース継手１２とを径方向に切断したときの断面を例示している。図４の（ｂ）には、本願発明の理解を容易にするために、入水側ホース継手１１の断面と排水側ホース継手１２の断面とを並べて表示されている。図４を参照すると、入水側ホース継手１１は入水側ホース継手細管１３と入水側ホース継手太管とを備えており、排水側ホース継手１２は排水側ホース継手細管１５と排水側ホース継手太管１６とを備えている。入水側ホース継手細管１３の断面積は、全ての排水側ホース継手細管１５の断面積の和よりも大きい。入水側ホース継手太管１４の断面積は入水側ホース継手細管１３の断面積よりも大きく、排水側ホース継手太管１６の断面積は排水側ホース継手細管１５の断面積よりも大きい。 FIG. 4 is a cross-sectional view showing the internal structure of the cleaning tool. FIG. 4A exemplifies a cross section when the cleaning tool 4 is cut along the flow path of the cleaning liquid, and FIG. 4B shows the diameters of the water inlet side hose joint 11 and the drainage side hose joint 12. The cross section when cut in the direction is illustrated. In FIG. 4B, the cross section of the water inlet side hose joint 11 and the cross section of the drainage side hose joint 12 are displayed side by side in order to facilitate understanding of the present invention. Referring to FIG. 4, the water inlet side hose joint 11 includes a water inlet side hose joint thin pipe 13 and a water inlet side hose joint thick pipe, and the drain side hose joint 12 includes a drain side hose joint thin pipe 15 and a drain side hose joint thick pipe. It has 16. The cross-sectional area of the water inlet side hose joint thin tube 13 is larger than the sum of the cross-sectional areas of all the drain side hose joint thin tubes 15. The cross-sectional area of the water inlet side hose joint thick pipe 14 is larger than the cross-sectional area of the water inlet side hose joint thin pipe 13, and the cross-sectional area of the drain side hose joint thick pipe 16 is larger than the cross-sectional area of the drain side hose joint thin pipe 15.

入水側ホース継手細管１３の断面積を、全ての排水側ホース継手細管１５の断面積の和よりも大きくすることにより、入水側ホース継手１１からの入水量は排水側ホース継手１２からの排水量に比べて多くなる。また、入水側ホース継手太管１４の断面積は入水側ホース継手細管１３の断面積よりも大きくし、排水側ホース継手太管１６の断面積は排水側ホース継手細管１５の断面積よりも大きくすることにより、入水側ホース継手１１から入水した洗浄液は排水側ホース継手１２へ流れ込みやすくなる。そのため、入水側ホース継手１１からの位置（距離）が異なる各排水側ホース継手１２に対しても洗浄液の流れ込み量に差が生じにくくなり、排出流量を均一化することが可能となる。 By making the cross-sectional area of the water entry side hose joint thin tube 13 larger than the sum of the cross-sectional areas of all the drain side hose joint thin tubes 15, the amount of water entering from the water entry side hose joint 11 becomes the amount of drainage from the drain side hose joint 12. It will be more than that. Further, the cross-sectional area of the water inlet side hose joint thick pipe 14 is larger than the cross-sectional area of the water inlet side hose joint thin pipe 13, and the cross-sectional area of the drain side hose joint thick pipe 16 is larger than the cross-sectional area of the drain side hose joint thin pipe 15. By doing so, the cleaning liquid that has entered from the water inlet side hose joint 11 can easily flow into the drain side hose joint 12. Therefore, the amount of the cleaning liquid flowing in is less likely to be different for each drainage side hose joint 12 having a different position (distance) from the water inlet side hose joint 11, and the discharge flow rate can be made uniform.

換言すると、本実施形態の洗浄ツール４は、ウォッシャーディスインフェクター２に設けられた洗浄液供給口の一つから供給される洗浄液を複数の洗浄対象に分配する分配器である。その洗浄ツール４において、入水側ホース継手１１が洗浄液を分岐ホルダー１０に供給する能力が、排水側ホース継手１２が洗浄液を洗浄対象（たとえば、医療用ハンドピース）に提供する能力よりも大きくなるように構成されている。 In other words, the cleaning tool 4 of the present embodiment is a distributor that distributes the cleaning liquid supplied from one of the cleaning liquid supply ports provided in the washer-disinfector 2 to a plurality of cleaning targets. In the cleaning tool 4, the ability of the water inlet side hose joint 11 to supply the cleaning liquid to the branch holder 10 is greater than the capacity of the drain side hose joint 12 to provide the cleaning liquid to the cleaning target (for example, a medical handpiece). It is configured in.

図５は、洗浄ツールへの接続の状態を示す斜視図である。図５を参照すると、洗浄ツール４の入水側ホース継手１１には一つのチューブ３が接続され、排水側ホース継ぎ手１２には複数のチューブ５が接続される。アタッチメント６はチューブ５を介して洗浄ツール４に複数本接続可能であり、接続位置の違いに関わらず同等量の洗浄液の排出が望める。
チューブ３およびチューブ５はフレキシブルな軟性シリコンチューブであるのに対し、チューブ３およびチューブ５に接続されるアタッチメント６のモータ接続部７、洗浄ツール４の入水側ホース継手１１および排水側ホース継ぎ手１２は金属製かつ、凹凸形状であるため、洗浄液が流れる際に生じる水圧下においてもチューブ３およびチューブ５は抜けずに留まることが可能である。 FIG. 5 is a perspective view showing a state of connection to the cleaning tool. Referring to FIG. 5, one tube 3 is connected to the water inlet side hose joint 11 of the cleaning tool 4, and a plurality of tubes 5 are connected to the drain side hose joint 12. A plurality of attachments 6 can be connected to the cleaning tool 4 via the tube 5, and the same amount of cleaning liquid can be expected to be discharged regardless of the difference in the connection position.
While the tube 3 and the tube 5 are flexible flexible silicone tubes, the motor connection portion 7 of the attachment 6 connected to the tube 3 and the tube 5, the water inlet side hose joint 11 and the drain side hose joint 12 of the cleaning tool 4 are Since it is made of metal and has an uneven shape, the tube 3 and the tube 5 can stay without coming off even under the water pressure generated when the cleaning liquid flows.
