Description

本発明は、留置用カテーテルもしくは留置用針（本明細書では、これらを「留置用輸液ライン」と総称する。）がその一端部に備える雄型のコネクタもしくは付属の三方活栓を含む活栓（本明細書では、これらを「中空コネクタ」と総称する。）における相手部材との接続部位の内周面と外周面とを同時に清拭できるようにした消毒用清拭具に関する技術である。   The present invention relates to a stopcock (this book) including a male connector or an attached three-way stopcock provided at one end of an indwelling catheter or an indwelling needle (in the present specification, these are collectively referred to as an “infusion liquid line for indwelling”). In the specification, these are generically referred to as “hollow connectors”.) This is a technique related to a disinfecting wiping tool that can simultaneously wipe the inner peripheral surface and the outer peripheral surface of the connection portion with the mating member.

留置用輸液ラインは、通常、患者の体外に引き出されている一端部に相手部材と接続させるための雄型のコネクタを備えており、該コネクタを介して相手部材である例えば血液透析装置の各流体ラインが備える雌型のコネクタとの間で迅速、かつ、容易に接続することができるようになっている。   The infusion line for indwelling typically includes a male connector for connecting to a mating member at one end that is drawn out of the patient's body, and each mating member, such as a hemodialyzer, is connected via the connector. It can be quickly and easily connected to a female connector provided in the fluid line.

A generally hollow body, the first end is sized to receive a luer therein, and the first end substantially engages a luer disposed therein; A plurality of bristles extending sufficiently toward the longitudinal axis, the second end including a compressible reservoir for containing fluid, and when the second end is compressed, the fluid is It is formed so as to be transferred toward one end.

また、特許文献２の「微生物汚染を低減するためのデバイス」は、留置ラインのコネクタと組み合わせて使用される医療用デバイスであって、仕切りによって互いから分離される近位部分および遠位部分を含むハウジングの近位部分および遠位部分の各々が個々の近位空洞および遠位空洞を規定し、これら近位空洞と遠位空洞とが流体連通にあり、遠位部分が留置ラインのコネクタと選択的に連結され、近位空洞内には微生物低減剤が配置され、近位空洞内に微生物低減剤を維持するために近位部分の端部を囲む変形可能部材を備えさせて形成されている。   In addition, the “device for reducing microbial contamination” of Patent Document 2 is a medical device used in combination with a connector of an indwelling line, and includes a proximal portion and a distal portion separated from each other by a partition. Each including a proximal portion and a distal portion of the housing defining an individual proximal and distal cavity, wherein the proximal and distal cavities are in fluid communication, and the distal portion is a connector of the indwelling line. Selectively coupled, formed with a microbial reducing agent disposed within the proximal cavity and having a deformable member surrounding the end of the proximal portion to maintain the microbial reducing agent within the proximal cavity. Yes.

しかし、特許文献１の開示技術は、ルアコネクタの外周部のみを洗浄しようとするものであるほか、その部材構成も複雑となる結果、消耗品にしてはコスト的に高価になる不都合があった。   However, the disclosed technique of Patent Document 1 is intended to clean only the outer peripheral portion of the luer connector, and as a result of complicating the member configuration, there is a disadvantage that it becomes expensive in terms of cost for consumables. .

また、特許文献２の開示技術は、ニードルのないコネクタの先端面と外周面とを洗浄し得るに止まるものであるほか、その部材構成も複雑となる結果、特許文献１の開示技術と同様に消耗品にしてはコスト的に高価になる不具合があった。   Further, the disclosed technique of Patent Document 2 is not limited to cleaning the distal end surface and the outer peripheral surface of the connector without the needle, and the member configuration is complicated. As a result, the disclosed technique of Patent Document 1 is the same. As a consumable, there was a problem that it was expensive in terms of cost.

It can be formed as two compartments as the surrounding portion. In addition, the inner surface pressure contact portion and the outer surface pressure contact portion have a large number of cross-cuts so that the length of one side in the axial direction of the absorbing member is shorter than the diameter of the hollow inner peripheral surface. It may be formed as a set of small-diameter columnar sections partitioned separately.

請求項１に係る発明によれば、導入口から差し込まれた中空コネクタの接続端部の内周面には、吸収部材における内面圧接部を、中空コネクタの接続端部の外周面と有底容器の前記周壁部の内周面との間に確保される空間部内には、吸収部材における外面圧接部をそれぞれ圧接させることができるので、有底容器の周壁部を手指で加圧しながら回すことで、吸収部材に含浸保持させた消毒液で中空コネクタの接続端部の中空内周面と外周面とを同時に清拭して確実に消毒することができる。   According to the first aspect of the present invention, the inner surface of the connection end of the hollow connector inserted from the introduction port is provided with the inner surface pressure contact portion of the absorbent member, the outer peripheral surface of the connection end of the hollow connector and the bottomed container. Since the outer surface pressure contact portion of the absorbent member can be pressed into the space secured between the peripheral wall portion and the inner peripheral surface of the peripheral wall portion, the peripheral wall portion of the bottomed container can be rotated while being pressed with fingers. The hollow inner peripheral surface and the outer peripheral surface of the connection end portion of the hollow connector can be wiped off simultaneously with the disinfectant liquid impregnated and held in the absorbent member, and can be surely sterilized.

また、消毒用清拭具の全体は、簡単な部材構成とすることでコストを低減させて形成することができるので、消耗品として安価に提供することができる。   In addition, the entire disinfecting wiping tool can be formed at a low cost as a consumable since it can be formed with a simple member configuration at a reduced cost.

請求項２に係る発明によれば、有底容器には、周壁部の内径が導入口方向に向けて拡径するテーパーが付与されているので、型抜き加工性に優れているのみならず、吸収部材の収容配置もより容易に行うことができる。   According to the invention according to claim 2, since the bottomed container is provided with a taper in which the inner diameter of the peripheral wall portion is increased toward the introduction port direction, not only has excellent die cutting processability, The absorbing member can be accommodated and arranged more easily.

請求項３に係る発明によれば、有底容器の前記導入口には、吸収部材の抜脱を阻止できるように内庇部が設けられているので、有底容器内に収容配置されている吸収部材が清拭作業中や作業終了後に有底容器内から抜け出るのを確実に阻止することができる。   According to the invention which concerns on Claim 3, since the inner collar part is provided in the said inlet of a bottomed container so that extraction of an absorption member can be prevented, it is accommodated and arrange | positioned in a bottomed container. It is possible to reliably prevent the absorbing member from coming out of the bottomed container during the wiping operation or after the completion of the operation.

請求項４に係る発明によれば、内面圧接部は、中空内周面の口径より大径な外径を有する柱状部とし、外面圧接部は、柱状部を囲む囲繞部とする２つの区画として形成されているので、中空コネクタの接続端部の中空内周面には柱状部を圧入させ、中空コネクタの接続端部の外周面と有底容器の周壁部の内周面との間に確保される空間部内には囲繞部を圧入させることで、中空コネクタの接続端部の中空内周面と外周面とを同時に清拭してより確実に消毒することができる。   According to the invention of claim 4, the inner surface pressure contact portion is a columnar portion having an outer diameter larger than the diameter of the hollow inner peripheral surface, and the outer surface pressure contact portion is two compartments that are surrounding portions surrounding the columnar portion. Because it is formed, a columnar part is pressed into the hollow inner peripheral surface of the connection end of the hollow connector, and secured between the outer peripheral surface of the connection end of the hollow connector and the inner peripheral surface of the peripheral wall of the bottomed container. By press-fitting the surrounding portion into the space portion, the hollow inner peripheral surface and the outer peripheral surface of the connection end of the hollow connector can be wiped off at the same time and more reliably sterilized.

請求項５に係る発明によれば、吸収部材の内面圧接部と外面圧接部とは、一辺の長さが中空内周面の口径より短寸となるように多数の交差切り込みを入れてなる細径柱状部の集合として形成されているので、中空コネクタの接続端部の中空内周面内には複数本の細径柱状部を圧入させ、中空コネクタの接続端部の外周面と有底容器の周壁部の内周面との間に確保される空間部内にはその余の多数の細径柱状部を圧入させることで、中空コネクタの接続端部の中空内周面と外周面とを同時に清拭してより確実に消毒することができる。   According to the invention of claim 5, the inner surface pressure contact portion and the outer surface pressure contact portion of the absorbing member are thinly formed by making a number of cross cuts so that the length of one side is shorter than the diameter of the hollow inner peripheral surface.

本発明に係る消毒用清拭具１１は、図４に示されているように留置用輸液ライン５１がその開放端部５２に備える中空コネクタ５３における接続対象たる適宜の相手部材、例えば透析装置の流体ラインが備える雌型のコネクタとの接続端部５４における中空内周面５５と外周面５６とを同時に清拭するために用いられるものである。なお、中空コネクタ５３としては、内径が４ｍｍ程度で、外径が７ｍｍ程度の鍔状となった接続端部５４と、該接続端部５４と留置用輸液ライン５１との間に位置する外径が５．５７ｍｍ程度で、長さが６７ｍｍ程度の細径管部５７とで形成されているものなどが使用される。   As shown in FIG. 4, the disinfecting wiping tool 11 according to the present invention is an appropriate mating member, for example, a dialysis machine, to be connected in the hollow connector 53 provided in the open end 52 of the infusion line 51 for indwelling. It is used for simultaneously wiping the hollow inner peripheral surface 55 and the outer peripheral surface 56 at the connection end portion 54 with the female connector provided in the fluid line. In addition, as the hollow connector 53, the inner diameter is about 4 mm and the outer diameter is about 7 mm, and the outer diameter located between the connection end 54 and the infusion line 51 for indwelling. Is formed of a thin tube portion 57 having a length of about 5.57 mm and a length of about 67 mm.

すなわち、消毒用清拭具１１は、図１に例示されているように、中空コネクタ５３の接続端部５４が差し込まれる導入口１３を一側端に有し、かつ、可撓性のある周壁部１４を備えてなる有底容器と１２、中空コネクタ５３の接続端部５４を消毒すべく消毒液を含浸保持させて有底容器１２内に収容配置される弾性のある吸収部材２２と、有底容器１２の導入口１３を開口可能に封止する封止材３２とで構成されている。   That is, as illustrated in FIG. 1, the disinfecting wiping tool 11 has an introduction port 13 into which the connection end portion 54 of the hollow connector 53 is inserted at one end, and has a flexible peripheral wall. A bottomed container having a portion 14, 12, an elastic absorbent member 22 that is stored and disposed in the bottomed container 12 by impregnating and holding a disinfectant solution to disinfect the connection end 54 of the hollow connector 53, It is comprised with the sealing material 32 which seals the inlet 13 of the bottom container 12 so that opening is possible.

これらのうち、有底容器１２は、ポリプロピレン、ポリエチレン、ナイロン、ポリカーボネイトなどを含む適宜の合成樹脂材を原材料としてその周壁部１４の肉厚が例えば撓み変形が可能な０．１〜１ｍｍ程度となり、かつ、周壁部１４の内径が底部１５側から導入口１３方向に向けて次第に拡径するテーパーが付与されるように型抜きすることで一体形成されている。   Of these, the bottomed container 12 is made of an appropriate synthetic resin material including polypropylene, polyethylene, nylon, polycarbonate, etc. as a raw material, and the thickness of the peripheral wall portion 14 is, for example, about 0.1 to 1 mm that can be flexibly deformed. In addition, the peripheral wall portion 14 is integrally formed by die-cutting so that a taper in which the inner diameter gradually increases from the bottom portion 15 toward the introduction port 13 is provided.

この場合、有底容器１２の導入口１３は、中空コネクタ５３の接続端部５４の外径である例えば７ｍｍ以上の口径が付与されて形成されており、これにより、中空コネクタ５３の接続端部５４を円滑に差し込めるようになっている。また、有底容器１２の周壁部１４の高さは、中空コネクタ５３の接続端部５４の軸方向での長さを上回る寸法が付与されて形成されている。   In this case, the inlet 13 of the bottomed container 12 is formed with a diameter of, for example, 7 mm or more, which is the outer diameter of the connection end 54 of the hollow connector 53, and thereby the connection end of the hollow connector 53. 54 can be inserted smoothly. Further, the height of the peripheral wall portion 14 of the bottomed container 12 is formed so as to have a dimension that exceeds the length in the axial direction of the connection end portion 54 of the hollow connector 53.

このため、有底容器１２は、その内部に中空コネクタ５３の接続端部５４をすっぽりと導入することができるほか、周壁部１４を外側から手指で少し押し込むことで容易に撓ませることができる可撓性を具備させることができることになる。なお、図示は省略しているが、有底容器１２の周壁部１４には、その高さ方向に沿わせて複数条のリブを設けておくことで、その強度をより高めておくこともできる。   For this reason, the bottomed container 12 can be easily bent by being able to completely introduce the connection end portion 54 of the hollow connector 53 into the inside thereof, and by slightly pushing the peripheral wall portion 14 with a finger from the outside. Flexibility can be provided. In addition, although illustration is abbreviate | omitted, in the surrounding wall part 14 of the bottomed container 12, the intensity | strength can also be raised more by providing the multiple rib along the height direction. .

また、有底容器１２の導入口１３には、吸収部材２２の抜け落ちを阻止する観点から少なくとも導入口１３の内側へとやや張り出させた例えば内径が７ｍｍ以上ある内庇部１６を設けておくのが好ましい。なお、有底容器１２の導入口１３には、図２に示すように外側へと張り出させた外庇部１７をも設けておくならば、封止材３２を安定的に接合固着するための接合代として活用することができる。   In addition, the inlet 13 of the bottomed container 12 is provided with an inner flange 16 having an inner diameter of, for example, 7 mm or more that slightly protrudes at least to the inside of the inlet 13 from the viewpoint of preventing the absorption member 22 from falling off. Is preferred. In addition, in order to stably join and fix the sealing material 32 if the outer opening 17 projecting outward is provided at the introduction port 13 of the bottomed container 12 as shown in FIG. It can be used as a joint allowance.

一方、発泡ポリウレタン、コットン、和紙などのような弾性と吸収性とに富む素材により形成される吸収部材２２は、導入口１３から差し込まれた接続端部５４における中空内周面５５内に弾性的に入り込んで圧接する内面圧接部２３と、接続端部５４の外周面５６と有底容器１２の周壁部１４の内周面１４ａとの間に確保される空間部１８へと弾性的に入り込んで圧接する外面圧接部２６とで形成されている。   On the other hand, the absorbing member 22 formed of a material rich in elasticity and absorbency such as foamed polyurethane, cotton, Japanese paper, etc. is elastic in the hollow inner peripheral surface 55 at the connection end 54 inserted from the inlet 13. The inner surface pressure contact portion 23 that enters and press-contacts, and the space portion 18 that is secured between the outer peripheral surface 56 of the connection end portion 54 and the inner peripheral surface 14a of the peripheral wall portion 14 of the bottomed container 12 elastically enters. It is formed by an outer surface pressure contact portion 26 that is in pressure contact.

この場合、吸収部材２２は、図１に示されているように吸収部材２２の軸方向での略中央部位に図４の中空コネクタ５５の中空内周面５５の口径より大径な外径を有する例えば円柱状を呈する柱状部２４を内面圧接部２３とすることで形成されている。   In this case, the absorbing member 22 has an outer diameter larger than the diameter of the hollow inner peripheral surface 55 of the hollow connector 55 of FIG. 4 at the substantially central portion in the axial direction of the absorbing member 22 as shown in FIG. For example, the columnar portion 24 having a columnar shape is formed as the inner surface pressure contact portion 23.

また、吸収部材２２は、吸収部材２２における外面圧接部２６は、柱状部２４を囲む囲繞部２７を外面圧接部２６とすることで形成されている結果、その全体も柱状部２４と囲繞部２７との２つの区画として形成されることになる。   Further, in the absorbing member 22, the outer surface pressure contact portion 26 in the absorbing member 22 is formed by setting the surrounding portion 27 surrounding the columnar portion 24 as the outer surface pressure contacting portion 26, and as a result, the entirety thereof is also the columnar portion 24 and the surrounding portion 27. Will be formed as two sections.

図３は、吸収部材２２の他例を示すものでありこの例における内面圧接部２３と外面圧接部２６とは、吸収部材２２の軸方向にそれぞれの一辺ａの長さが中空内周面５５の口径よりは短寸となるように多数の交差切込み２９を入れて各別に区画される細径柱状部２８の集合として角柱状に形成されている。なお、この場合の吸収部材２２は、図示は省略してあるが、多数の細径柱状部２８を有する円柱状に形成することもできる。   FIG. 3 shows another example of the absorbing member 22. In this example, the inner surface pressing portion 23 and the outer surface pressing portion 26 have a hollow inner peripheral surface 55 each having a side a in the axial direction of the absorbing member 22. It is formed in a prismatic shape as a set of small-diameter columnar portions 28 that are partitioned by inserting a large number of cross-cuts 29 so as to be shorter than the diameter of the diameter. In this case, the absorbing member 22 is not shown, but can also be formed in a cylindrical shape having a large number of small-diameter columnar portions 28.

このため、吸収部材２２の各細径柱状部２８は、その位置により内面圧接部２３として中空コネクタ５３の接続端部５４における中空内周面５５内へと圧入されたり、中空コネクタ５３の接続端部５４の外周面５６と有底容器１２の周壁部１４の内周面１４ａとの間に確保される空間部内へと圧入されたりすることになる。   For this reason, each small-diameter columnar portion 28 of the absorbing member 22 is press-fitted into the hollow inner peripheral surface 55 of the connection end portion 54 of the hollow connector 53 as the inner surface pressure contact portion 23 depending on the position, or the connection end of the hollow connector 53 It is press-fitted into a space portion secured between the outer peripheral surface 56 of the portion 54 and the inner peripheral surface 14a of the peripheral wall portion 14 of the bottomed container 12.

また、図１に示す吸収部材２２の内面圧接部２３である柱状部２４と外面圧接部２６である囲繞部２７とは、その基端部３０において一体に連結させておくのが望ましいが、各別に形成するものであってもよい。   Further, it is desirable that the columnar portion 24 that is the inner surface pressure contact portion 23 and the surrounding portion 27 that is the outer surface pressure contact portion 26 of the absorbing member 22 shown in FIG. It may be formed separately.

さらに、図３に示す吸収部材２２における各細径柱状部２８は、基端部３０に到達する深さまでは交差切込み２９が入り込んでおらず、したがって基端部３０側が一体に連結されている。   Further, in each of the narrow columnar portions 28 in the absorbing member 22 shown in FIG. 3, the cross notch 29 does not enter at a depth reaching the base end portion 30, and therefore the base end portion 30 side is integrally connected.

しかも、吸収部材２２は、外力を加えない自然の状態のもとでは滴下しない程度の量の消毒液、例えばエタノール８０％溶液を主成分とする消毒液を含浸保持させた上で、有底容器１２内に収容配置されている。この場合、吸収部材２２の基端部３０側は、有底容器１２の内底面１５に接合固着しておくのが好ましいが、所望により非接合状態で配置しておくこともできる。   In addition, the absorbent member 22 is impregnated with a disinfecting solution in an amount that does not dripping under a natural state where no external force is applied, for example, a disinfecting solution mainly composed of an 80% ethanol solution, and then a bottomed container. 12 is housed and arranged. In this case, the base end 30 side of the absorbent member 22 is preferably bonded and fixed to the inner bottom surface 15 of the bottomed container 12, but may be arranged in a non-bonded state if desired.

プラスチックシート材やアルミニウムシート材などで形成される封止材３２は、吸収部材２２を収容配置した状態のもとで有底容器１２の導入口１３を封止するために用いられるものであり、例えば開口縁１３ａを含む内庇部１６や、図２に示す外庇部１７を含めて適宜の接合手段を用いて開口可能に接合される。なお、封止材３２には、図１に示すようにその開口時に手指で抓めるように抓み片３３を突設しておくのが望ましい。   The sealing material 32 formed of a plastic sheet material, an aluminum sheet material or the like is used for sealing the inlet 13 of the bottomed container 12 under the state where the absorbing member 22 is accommodated and disposed. For example, the inner flange portion 16 including the opening edge 13a and the outer flange portion 17 shown in FIG. In addition, as shown in FIG. 1, it is desirable to project the squeeze piece 33 on the sealing material 32 so as to squeeze it with fingers when it is opened.

次に、このような構成からなる本発明の作用・効果を説明すれば、封止材３２を有底容器１２側から引き剥がした上で、図５に示すように留置用輸液ライン５１の開放端部５２側を一方の手指Ｆ１側で保持し、有底容器１２における周壁部１４側を他方の手指Ｆ２側で保持し、留置用輸液ライン５１がその開放端部５２に備える接続用の中空コネク５３の接続端部５４を導入口１３から差し込んだ後、周壁部１４側を他方の手指Ｆ２側で軽く押し込みながら有底容器１２を回す。 Next, the operation and effect of the present invention having such a configuration will be described. After the sealing material 32 is peeled off from the bottomed container 12, the infusion line 51 for indwelling is opened as shown in FIG. The end 52 side is held on one finger F 1 side, the peripheral wall 14 side in the bottomed container 12 is held on the other finger F 2 side, and the infusion line 51 for indwelling is provided for the open end 52. after inserting the connecting end portion 54 of the hollow connector 53 from the inlet 13, turns the bottomed container 12 while pushing lightly the peripheral wall portion 14 side at the other fingers F 2 side.

このとき、導入口１３から差し込まれた中空コネクタ５３の接続端部５４の中空内周面５５には、吸収部材２２における内面圧接部２３が、中空コネクタ５３の接続端部５４の外周面５６と有底容器１２の周壁部１４の内周面１４ａとの間に確保される空間部内には、吸収部材２２における外面圧接部２６がそれぞれ圧接する結果、吸収部材２２に含浸保持させた消毒液で中空コネクタ５３の接続端部５４の中空内周面５５と外周面５６とを同時に清拭して確実に消毒することができる。   At this time, on the hollow inner peripheral surface 55 of the connection end portion 54 of the hollow connector 53 inserted from the introduction port 13, the inner surface pressure contact portion 23 of the absorbing member 22 is connected to the outer peripheral surface 56 of the connection end portion 54 of the hollow connector 53. In the space secured between the inner peripheral surface 14a of the peripheral wall portion 14 of the bottomed container 12, the outer surface pressure contact portion 26 of the absorption member 22 is in pressure contact with each other. As a result, the disinfectant liquid impregnated and held in the absorption member 22 is used. The hollow inner peripheral surface 55 and the outer peripheral surface 56 of the connection end portion 54 of the hollow connector 53 can be wiped off at the same time and reliably sterilized.

しかも、消毒用清拭具１１の全体は、簡単な部材構成とすることでコストを低減させて形成することができるので、消耗品として安価に提供することができる。   In addition, the entire disinfecting wiping tool 11 can be formed at a low cost as a consumable since it can be formed with a simple member configuration at a reduced cost.

また、有底容器１２の周壁部１４の内径が導入口１３方向に向けて拡径するようにテーパーが付与されている場合には、型抜き加工性に優れているのみならず、吸収部材の収容配置もより容易に行うことができる。   Moreover, when the taper is provided so that the inner diameter of the peripheral wall portion 14 of the bottomed container 12 is increased in the direction toward the introduction port 13, not only the die cutting processability is excellent, but also the absorption member Storage arrangement can also be performed more easily.

さらに、有底容器１２の導入口１３に吸収部材２２の抜脱を阻止できるように内庇部１６が設けられている場合には、有底容器１２内に収容配置されている吸収部材２２が清拭作業中や作業終了後に有底容器１２内から抜け出るのを確実に阻止することができる。   Further, when the inner flange portion 16 is provided at the introduction port 13 of the bottomed container 12 so that the absorption member 22 can be prevented from being pulled out, the absorbing member 22 accommodated in the bottomed container 12 is provided. It is possible to reliably prevent the bottomed container 12 from slipping out during or after the wiping operation.

また、内面圧接部２３を中空内周面５５の口径より大径な外径を有する柱状部２４として形成し、外面圧接部２６を柱状部２４を囲む囲繞部２７とする２つの区画に分割してある場合には、中空コネクタ５３の接続端部５４の中空内周面５５には柱状部２４を圧入させ、中空コネクタ５３の接続端部５４の外周面５６と有底容器１２の周壁部１４の内周面１４ａとの間に確保される空間部内には囲繞部２７を圧入させることができるので、中空コネクタ５３の接続端部５４の中空内周面５５と外周面５６とを同時に清拭してより確実に消毒することができる。   In addition, the inner surface pressure contact portion 23 is formed as a columnar portion 24 having an outer diameter larger than the diameter of the hollow inner peripheral surface 55, and the outer surface pressure contact portion 26 is divided into two sections which are surrounding portions 27 surrounding the columnar portion 24. In this case, the columnar portion 24 is press-fitted into the hollow inner peripheral surface 55 of the connection end portion 54 of the hollow connector 53, and the outer peripheral surface 56 of the connection end portion 54 of the hollow connector 53 and the peripheral wall portion 14 of the bottomed container 12. Since the surrounding portion 27 can be press-fitted into the space secured between the inner peripheral surface 14a and the inner peripheral surface 14a, the hollow inner peripheral surface 55 and the outer peripheral surface 56 of the connection end portion 54 of the hollow connector 53 are simultaneously wiped. And can be sterilized more reliably.

また、吸収部材２２の内面圧接部２３と外面圧接部２６とを一辺の長さが中空内周面５５の口径より短寸となるように多数の交差切込み２９を入れてなる細径柱状部２８の集合として形成されている場合には、中空コネクタ５３の接続端部５４の中空内周面５５内には複数本の細径柱状部２８を圧入させ、中空コネクタ５３の接続端部５４の外周面５６と有底容器１２の周壁部１４の内周面１４ａとの間に確保される空間部内にはその余の多数の細径柱状部２８を圧入させることで、中空コネクタ５３の接続端部５４の中空内周面５５と外周面５６とを同時に清拭してより確実に消毒することができる。   Further, the narrow columnar portion 28 having a large number of cross cuts 29 so that the length of one side of the inner surface pressure contact portion 23 and the outer surface pressure contact portion 26 of the absorbing member 22 is shorter than the diameter of the hollow inner peripheral surface 55. Are formed in the hollow inner peripheral surface 55 of the connection end 54 of the hollow connector 53, and a plurality of small-diameter columnar portions 28 are press-fitted into the outer periphery of the connection end 54 of the hollow connector 53. The connecting end portion of the hollow connector 53 is formed by press-fitting a large number of small-diameter columnar portions 28 into the space portion secured between the surface 56 and the inner peripheral surface 14 a of the peripheral wall portion 14 of the bottomed container 12.
