Description

[Technical field]

[0001] The present invention relates to a connector cleaner that cleans connectors for connecting medical tubing. [Background technology]

[0002] Conventionally, efforts have been made to prevent connectors for connecting medical tubes from being connected incorrectly. As part of these efforts, standards have been introduced to promote the prevention of medical accidents and ensure a stable supply through international harmonization. For enteral nutrition, there are standards in which the connector connected to the patient is the male side and the connector opposite the patient is the female side. In such standards, due to the structure, for example, nutrients related to enteral nutrition may remain in the internal space of the male connector on the patient side. As a result, there is a risk of hygienic inconvenience such as the generation of bacteria in the male connector that is indwelled while connected to the patient. In order to eliminate such a risk, a technology has been disclosed in which the nutrients are wiped off with a material that absorbs them, but there is a possibility that the nutrients cannot be completely wiped off and may solidify.

[0003] [Patent Document 1] JP 2017-099738 A Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made in view of the above circumstances, and has an object to provide a technique that enables medical male connectors to be cleaned more easily. [Means for solving the problem]

[0005] In order to solve the above-mentioned problems, the present invention employs the following configuration. A connector cleaner for cleaning a medical male connector having a cylindrical male connector body with a fluid flow path passing therethrough in the axial direction, and a substantially cylindrical coupler that is connected to the male connector body at a rear end side thereof and surrounds the male connector body, a connecting portion that connects the male connector body and the coupler, a side surface of the male connector body, and an inner surface of the coupler. A cleaning liquid ejection portion that ejects a cleaning liquid from the front of the medical male connector into an internal space of the medical male connector that is surrounded by the side surface of the male connector body and the inner surface of the coupler. a housing portion for housing the medical male connector; a discharge portion that is in communication with the housing portion and discharges the cleaning liquid sprayed into the internal space of the medical male connector to the outside while the medical male connector is housed in the housing portion; an insertion portion forming body having an insertion portion through which the medical male connector is inserted when the medical male connector is accommodated in the accommodation portion; Equipped with The insertion portion forming body includes an elastic member that is elastically deformed by the insertion of the medical male connector.

[0006] According to this, by the simple action of elastically deforming the insertion portion formed in the insertion portion forming body and inserting the medical male connector through the insertion portion, the medical male connector can be accommodated in the accommodation portion of the connector cleaner, and the medical male connector can be more easily cleaned using the connector cleaner. The insertion part forming body may be formed integrally with the housing part, or may be formed separately from the housing part. In addition, the insertion part forming body may be formed by bonding or fusing the elastic member to the holding member. The mounting member 10 may be fixed and held by a fastener.

[0007] In the present invention, The insertion portion may have a hole through which the medical male connector is inserted.

[0008] According to this, the medical male connector can be accommodated in the accommodation portion of the connector cleaner by the simple action of inserting the medical male connector into the hole, thereby simplifying the operating process of the connector cleaner when cleaning the medical male connector.

[0009] The present invention also provides a method for producing a method for manufacturing a semiconductor device comprising the steps of: A connector cleaner for cleaning a medical male connector having a cylindrical male connector body with a fluid flow path passing therethrough in the axial direction, and a substantially cylindrical coupler that is connected to the male connector body at a rear end side thereof and surrounds the male connector body, a connecting portion that connects the male connector body and the coupler, a side surface of the male connector body, and an inner surface of the coupler. A cleaning liquid ejection portion that ejects a cleaning liquid from the front of the medical male connector into an internal space of the medical male connector that is surrounded by the side surface of the male connector body and the inner surface of the coupler. a housing portion for housing the medical male connector; a discharge portion that is in communication with the housing portion and discharges the cleaning liquid sprayed into the internal space of the medical male connector to the outside while the medical male connector is housed in the housing portion; a transport member connection portion connected to a cleaning liquid transport member that transports the cleaning liquid and to a flow path that communicates with the cleaning liquid jetting portion; Equipped with This connector cleaner includes the transport member connection portion and the cleaning liquid spraying portion, and is characterized in that a check valve is provided in a flow path through which the cleaning liquid flows from the transport member connection portion toward the cleaning liquid spraying portion to prevent backflow of the cleaning liquid.

[0010] In this way, by providing a check valve in a flow path that includes a transport member connection portion and a cleaning liquid ejection portion and through which cleaning liquid flows from the transport member connection portion to the cleaning liquid distribution portion, it is possible to prevent backflow of the cleaning liquid that has been used to clean and contaminate the medical male connector, thereby preventing contamination of various parts upstream of the check valve.

[0011] The present invention also provides a method for producing a method for manufacturing a semiconductor device comprising the steps of: A connector cleaner for cleaning a medical male connector having a cylindrical male connector body with a fluid flow path passing therethrough in the axial direction, and a substantially cylindrical coupler that is connected to the male connector body at a rear end side thereof and surrounds the male connector body, a connecting portion that connects the male connector body and the coupler, a side surface of the male connector body, and an inner surface of the coupler. A cleaning liquid ejection portion that ejects a cleaning liquid from the front of the medical male connector into an internal space of the medical male connector that is surrounded by the side surface of the male connector body and the inner surface of the coupler. a housing portion for housing the medical male connector, the housing portion having an opening through which the medical male connector is inserted in the axial direction of the medical male connector housed in the housing portion relative to the cleaning liquid ejection portion; a discharge portion that is in communication with the housing portion and discharges the cleaning liquid sprayed into the internal space of the medical male connector to the outside while the medical male connector is housed in the housing portion; A cover member that opens and closes the opening of the storage portion; Equipped with The connector cleaner is characterized in that at least a portion of the cover member moves in a direction perpendicular to the axial direction of the medical male connector accommodated in the accommodation portion to open and close the opening.

[0012] According to this, at least a part of the cover member is fixed to the housing of the medical male connector. The opening can be opened and closed by moving the cover member in a direction perpendicular to the axial direction. Since the opening is provided in the axial direction of the medical male connector housed in the housing portion relative to the cleaning liquid jetting portion, by moving at least a part of the cover member in a direction perpendicular to the axial direction, at least a part of the cover member can be easily removed from the path of the medical male connector that is to be inserted from the opening toward the cleaning liquid jetting portion. Therefore, the medical male connector can be easily housed in the housing portion, and the man-hours required to open and close the cover member when cleaning the medical male connector with the connector cleaner can be reduced. This makes it easier to clean the medical male connector using the connector cleaner. Here, orthogonal does not necessarily mean an angle of 90° strictly, but means a range including 90°.

[0013] In the present invention, The cover member may include a first cover member and a second cover member that move from either side in a direction perpendicular to the axial direction of the medical male connector accommodated in the accommodation portion to open and close the opening.

[0014] According to this, the opening can be opened and closed by moving the first and second cover members on both sides in a direction perpendicular to the axial direction of the medical male connector housed in the housing. Since the opening is provided in the axial direction of the medical male connector housed in the housing relative to the cleaning liquid ejection part, by moving the first and second cover members on both sides in a direction perpendicular to the axial direction, at least a part of the first and second cover members can be easily removed from the path of the medical male connector that is to be inserted from the opening toward the cleaning liquid ejection part. Therefore, the medical male connector can be easily housed in the housing, and the man-hours required for opening and closing the cover members when cleaning the medical male connector with the connector cleaner can be reduced.

[0015] In the present invention, The first and second cover members may be rotatably supported around a rotation axis parallel to the axial direction of the medical male connector accommodated in the accommodation portion, and the opening may be opened and closed by rotating around the rotation axis.

[0016] According to this, the first and second lid members can be configured in a scissor shape, that is, the opening can be opened and closed by the first and second lid members with a simple operation like operating scissors, so that the medical male connector can be easily accommodated in the accommodation portion and the number of steps required to open and close the lid members when cleaning the medical male connector with a connector cleaner can be reduced.

[0017] In the present invention, A restricting means may be provided for restricting movement of the cover member when the opening is closed.

[0018] This can prevent the cover member from moving during cleaning and causing at least a portion of the opening to open.

[0019] In the present invention, the male connector body is provided with an attachment portion for attaching an elastic ring to an outer periphery of the male connector body rearward of the coupler, the attachment portion having a wall portion erected in a direction perpendicular to the axial direction and a bottom portion provided in the axial direction, At least a part of the cover member closing the opening may be configured to press the elastic ring attached to the attachment part against at least one of the wall part and the bottom part. good.

[0020] This makes it possible to maintain a liquid-tight seal between at least a portion of the lid member and the male connector body, thereby preventing cleaning liquid from leaking out from between the lid member and the male connector body.

[0021] In the present invention, the means for solving the above problems can be used in combination as far as possible. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following describes an embodiment of the present invention. The embodiment described below is an example of the present invention, and the technical scope of the present invention is not limited to the following aspect.

[0025] <Example 1> FIG. 1 shows a vertical cross-sectional view of a male connector 100 for enteral nutrition, which is an example of a subject to be cleaned by the connector cleaner according to the present embodiment. In FIG. 1, the lower side corresponds to the tip side of the male connector 100, and the upper side corresponds to the rear end side. In FIG. 1, the dashed line Ax0 indicates the axial direction of the male connector 100. The male connector 100 in this embodiment is provided with a connector body 101 as a male connector body having a flow path 101a therein that communicates with a tube 102. The connector body 101 has a tapered (also called a truncated cone) side surface 101b whose outer diameter becomes smaller toward the tip side. The male connector 100 corresponds to the medical male connector of the present invention. Note that the subject to be cleaned by the connector cleaner is not limited to a male connector for enteral nutrition, and may be a connector used in medical procedures such as dialysis.

[0026] A generally cylindrical coupler 103 is provided around the connector body 101 so as to surround the outer periphery of the connector body 101. A coupler coupling portion 103b provided on the rear end side of the inner surface of the coupler 103 forms a connector coupling portion 100a as a coupling portion together with a body coupling portion 101c provided on the rear end side of a side surface 101b of the connector body 101. In the connector coupling portion 100a, the coupler 103 is coupled to the connector body 101 so as to be rotatable around an axis and not to come off to the tip side. The space surrounded by the side surface 101b of the connector body 101, the inner surface of the coupler 103, and the connector coupling portion 100a is hereinafter referred to as the internal space of the male connector 100. Note that the coupling portion may be fixed so that the coupler 103 cannot rotate around an axis relative to the connector body 101. That is, although a free-lock connector is shown as an example in this embodiment, a fixed-lock connector may also be used.

[0027] Further, a disk-shaped rib portion 101d is formed on the rear side of the body coupling portion 101c of the connector body 101, protruding outward from the entire side surface of the connector body 101, and functions as a stopper to prevent the coupler 103 from moving excessively toward the rear end side of the connector body 101. A disk-shaped rib portion 101e is similarly formed on the rear side of the rib portion 101d, protruding outward from the entire side surface of the connector body 101. Between the rib portion 101d and the rib portion 101e, a bottom portion 101f provided parallel to the axial direction of the connector body 101, and the rib portion 101d and the rib portion 101e form a groove 101g over the entire circumference, in which an elastic ring (not shown) is attached. Here, the rib portions 101d and 101e correspond to the wall portion of the present invention erected in a direction perpendicular to the axial direction of the connector body 101, the bottom portion 101f corresponds to the bottom portion of the present invention, and the groove 101g corresponds to the attachment portion of the present invention. Furthermore, the inner diameter of the rear end side of the flow path 101a provided in the connector main body 101 is expanded to form a large diameter portion 101h, into which the tube 102 can be press-fitted. A female thread portion 103a is formed on the inner surface of the coupler 103, and the coupler 103 can be screwed to a female connector (not shown) having a male thread portion. Note that the disk-shaped rib portion 101d is not essential, and the coupler 103 may be designed to move freely toward the rear end side relative to the connector main body 101. In other words, the coupler 103 may be a slide coupler.

[0028] In this embodiment, the tube 102 shown in FIG. 1 is connected to the living body, and the male connector 100 is screwed to a female connector (not shown), so that a fluid such as nutrient solution is supplied to the living body from the female connector side via the male connector 100 and the tube 102.

[0029] FIG. 2 shows an overall perspective view of the cleaning unit 10 for fixing and cleaning the male connector 100 in this embodiment. FIG. 3 shows a front view (FIG. 3(A)) and a right side view (FIG. 3(B)) of the cleaning unit 10. ), rear view (FIG. 3(C)), plan view (FIG. 3(D)), and bottom view (FIG. 3(E)). FIG. 4(A) shows an exploded right side view of the cleaning unit 10, and FIG. 4(B) shows an exploded AA cross-sectional view of the cleaning unit 10. FIG. 5(A) shows an exploded perspective view of the cleaning unit 10 from the front right side, and FIG. 5(B) shows an exploded perspective view of the cleaning unit 10 from the rear left side. FIG. 6 shows an AA cross-sectional view of the cleaning unit 10. Here, the front, rear, plan view, bottom, left and right are defined based on the view of the cleaning unit 10 in a position in which the axial direction of the main body 11 is upright (the position of FIG. 3(A)) from the direction in which the drainage tube 112 of the cleaning unit 10 protrudes. In FIG. 6, the dashed line Ax1 indicates the axial direction of the cleaning unit 10.

[0030] The cleaning unit 10 is mainly composed of a substantially cylindrical main body 11, a cover member 12, and a cleaning liquid tube connecting member 13. The cleaning unit 10 corresponds to the connector cleaner of the present invention.

[0031] The main body 11 has a cylindrical connector mounting portion 111 to which the male connector 100 is attached, a drainage tube portion 112 for discharging cleaning fluid after cleaning the male connector 100, and a connection member mounting portion 113 to which the cleaning fluid tube connecting member 13 is attached. The main body 11 is made of a hard material. The main body 11 may be configured to be disposable and to be replaced after one or more cleanings.

[0032] The connector mounting portion 111 includes an opening 1111 to which the cover member 12 is attached and into which the male connector 100 is inserted, and has a generally cylindrical hollow interior in which the male connector 100 is housed. The end of the wall portion 1112, which surrounds the opening 1111 and extends in the axial direction like a cylinder, on the opening 1111 side is fitted into a groove 1223 of the cover member 12 described later, so that the cover member 12 is mounted on the main body 2. In addition, engagement protrusions 1112d and 1112e that protrude in the outer diameter direction are formed on the end of the outer peripheral surface of the wall portion 1112 on the opening 1111 side. The engagement protrusions 1112d and 1112e extend over a portion of the circumferential direction, and are formed so that the amount of protrusion in the outer diameter direction increases from the opening 1111 side toward the connection member mounting portion 113 side along the axial direction.

[0033] The wall 1112 of the connector mounting portion 111 includes an expanded diameter portion 1112a expanding toward the opening 1111, and a small diameter portion 1112d having substantially the same diameter as the opening 1111, via a step portion 1112b and a tapered portion 112c, on the opposite side of the expanded diameter portion 1112a from the opening 1111. The tapered portion 112c has a function of guiding the male connector 100 to the small diameter portion 1112d when the male connector 100 is inserted from an insertion hole 121a of the cover member 12 described later. The inner diameter of the small diameter portion 1112d is slightly larger than the outer diameter of the coupler 103 of the male connector 100. When the male connector 100 is mounted on the connector mounting portion 111, a gap is formed between the wall 1112 and the coupler 103, forming a flow path for the cleaning liquid. The hollow interior of the connector mounting portion 111 is separated from the connection member mounting portion 113 by a partition wall 1113, and an end face 1113a of the partition wall 1113 on the small diameter portion 1112d side is provided with a groove 1113b that is annular in plan view and can accommodate the tip of the connector body 101 when the male connector 100 is attached. A cylindrical protrusion 1113c that is inserted into the flow path 101a of the connector body 101 is formed on the center side of the inner circumference of the groove 1113b. The protrusion 1113c forms an isolation portion that isolates the flow path 101a of the connector body 101 from the flow path of the cleaning liquid. When the male connector 100 is attached to the connector mounting portion 111, the tip of the coupler 103 abuts against the end face 1113a on the small diameter portion 1112d side on the outer circumferential side of the groove 1113b. A groove for mounting an elastic ring may be provided on end face 1113a with which the tip of coupler 103 abuts, so that the tip of coupler 103 abuts against the elastic ring. In this way, male connector 100 can be supported elastically so as to be movable up and down. Connector mounting portion 111 corresponds to the housing portion of the present invention.

[0034] At the bottom of the groove 1113b of the end face 1113a, a cleaning liquid ejection hole 111 is provided as a cleaning liquid ejection part. 3d1-1113d4 (see FIG. 9(D)) are arranged at equal intervals in the circumferential direction. These cleaning liquid ejection holes 1113d1-1113d4 communicate with a cleaning liquid inlet hole opening in an end face 1113e of the partition wall 1113 on the connection member mounting portion 113 side via an in-wall flow path. When cleaning liquid is pressure-fed from the outside to the cleaning liquid inlet hole, the cleaning liquid is ejected from the cleaning liquid ejection holes 1113d1-1113d4 located in front of the male connector 100.

[0035] A first cleaning liquid discharge hole 112b communicating with a cleaning liquid discharge path 112a penetrating the inside of the drain tube part 112 is opened at the end part of the wall part 1112 of the connector attachment part 111 on the partition wall 1113 side, and a second cleaning liquid discharge hole 112c similarly communicating with the cleaning liquid discharge path 112a is opened at the side wall of the groove 1113b. In this embodiment, the first cleaning liquid discharge hole 112b and the second cleaning liquid discharge hole 112c are only separated via the coupler 103 when the male connector 100 is attached, so they may be formed at the same time as forming the cleaning liquid discharge path 112a. The cleaning liquid discharge path 112a corresponds to the discharge part of the present invention.

[0036] The connection member mounting portion 113 is provided on the main body 11 on the opposite side to the connector mounting portion 111 in the axial direction. The connection member mounting portion 113 has a large diameter portion 1131 including an opening 1131a into which the cleaning liquid tube connecting member 13 is inserted, and a small diameter portion 1133 continuing to the large diameter portion 1131 via a reduced diameter portion 1132. The opening 1131a of the large diameter portion 1131 has a shape in which a circular opening 1131a1 into which the tip portion 134 of the cleaning liquid tube connecting member 13 can be inserted is continued to sector-shaped openings 1131a2 and 113a3 that expand in the radial direction on both sides in the diametrical direction. The sector-shaped openings 1131a2 and 113a3 are formed from the end face on the opening 1131a side to a predetermined depth on the connector mounting portion 111 side along the axial direction. Then, grooves 1131b2 and 1131b3 are formed in the circumferential direction, which are recessed from the inner peripheral surface of the large diameter portion 1131 to the outer diameter side, continuing from the end of the sector-shaped portion of the openings 1131a2 and 1131a3 on the connector mounting portion 111 side. The grooves 1131b2 and 1131b3 are formed in the clockwise direction when viewed along the axial direction from the cleaning liquid tube side relative to the ends of the openings 1131a2 and 113a3, and are approximately wedge-shaped in which the axial height of the grooves 1131b2 and 1131b3 decreases as the clockwise direction progresses. The outer diameter sides of these approximately wedge-shaped grooves 1131b2 and 1131b3 penetrate to the outer peripheral surface, forming wedge-shaped holes 1131c2 and 1131c3. The holes 1131c2 and 1131c3 are rotationally symmetrical with respect to the axis, and when viewed from the cleaning liquid tube side, form a generally wedge shape with the axial height decreasing clockwise. Of the openings 1131a of the large diameter portion 1131, the circular opening 1131a1 communicates with the small diameter portion 1133 in the axial direction. An end face 1113e of the partition wall 1113 on the side of the small diameter portion 1133 is provided with cleaning liquid inlet holes communicating with the above-mentioned cleaning liquid ejection holes 1113d1-1113d4.

[0037] The cover member 12 is substantially cylindrical with a bottom. It has a substantially disc-shaped end surface 121 and a substantially cylindrical wall portion 122. An insertion hole 121a for inserting the male connector 100 is opened in the center of the end surface 121. The size of the insertion hole 121a may be large enough to allow the male connector 100 to be inserted by elastic deformation, and is not limited to the case where it is pressed against the outer circumferential surface of the connector body 101 of the male connector 100 accommodated in the connector attachment portion 111. The size of the insertion hole 121a may be large enough to have a gap between the insertion hole 121a and the connector body 101. The wall portion 122 includes an outer wall portion 1221 on the outer diameter side and an inner wall portion 1222, and a cylindrical groove 1223 having an axial depth is provided between the outer wall portion 1221 and the inner wall portion 1222 over the entire circumference. Holes 1221a and 1221b extending in a part of the circumferential direction are provided at a position on the end face 121 side of the outer wall portion 1221. The holes 1221a and 1221b penetrate the outer peripheral surface of the outer wall portion 1221 from the groove 1223 side, and are provided at positions rotationally symmetrical to each other about the axis. The cover member 12 is formed of an elastic material such as a PVC sheet, rubber, elastomer, or polyethylene. The cover member 12 is not limited to being formed integrally from an elastic material as described above, but may be configured such that a portion including the insertion hole 121a is formed from the above-mentioned elastic material and is held by a holding portion by adhesion, welding, or the like. In this case, the holding portion is formed by the connector mounting portion 1. The cover member 12 may be provided integrally with the insertion portion 11 or may be provided separately. The cover member 12 corresponds to the insertion portion forming body of the present invention.

[0038] The cleaning liquid tube connection member 13 is a member to which a cleaning liquid tube, which is a cleaning liquid transport member that transports cleaning liquid pressure-fed by a pump from a cleaning liquid tank (not shown), is connected, and is connected and fixed to the main body 11 by the practitioner. The cleaning liquid tube connection member 13 is substantially cylindrical. The cleaning liquid tube connection member 13 has a hollow interior 131. The hollow interior 131 penetrates in the axial direction from an end face 132 on the cleaning liquid tube side to an end face 133 on the main body 11 side. The hollow interior 131 includes a large diameter portion 131a into which the cleaning liquid tube is inserted, a reduced diameter portion 131b that is continuous with the large diameter portion 131a and reduces in diameter toward the main body 11 side, a small diameter portion 131c that is continuous with the reduced diameter portion 131b, and an expanded diameter portion 131d that is continuous with the small diameter portion 131c, expands in diameter toward the main body 11 side, and opens to the end face 133 on the main body 11 side. The cleaning liquid tube connecting member 13 may be integral with the main body 11. The cleaning liquid tube connecting member 13 corresponds to the transport member connecting portion of the present invention.

[0039] A groove 1341 is formed around the entire circumference on the outer peripheral surface of the tip portion 134 side of the cleaning liquid tube connection member 13, which is recessed on the inner diameter side, in order to mount the elastic ring 5 on the main body portion 2 side. On the outer peripheral surface of the tip portion 134 of the cleaning liquid tube connection member 13, on the opposite side of the groove 1341 from the main body portion 11, engagement protrusions 1342a and 1342b that engage with the main body portion 11 are formed. The engagement protrusions 1342a and 1342b are plate-shaped, extending over a portion of the circumference and protruding to the outer diameter side. The axial thickness of the engagement protrusions 1342a and 1342b is formed so as to decrease clockwise when viewed from the cleaning liquid tube side, and the engagement protrusions 1342a and 1342b are approximately wedge-shaped when viewed from the outer diameter side. The engagement protrusions 1342a and 1342b are also arranged rotationally symmetrical with respect to the axis of the cleaning liquid tube connection member 13.

[0040] The cleaning liquid tube connecting member 13 has a disk-shaped flange 1343 formed on the cleaning liquid tube side of the engagement protrusions 1342a and 1342b, which protrudes outward over the entire circumference. Furthermore, the cleaning liquid tube connecting member 13 has plate-shaped wings 1344a and 1344b formed on the outer circumferential surface thereof, which extend from the end face of the flange 1343 on the cleaning liquid tube side along the axial direction and protrude outward. The wings 1344a and 1344b are provided to reliably and easily grip the cleaning liquid tube connecting member 13 when inserting the cleaning liquid tube into the hollow interior 131. The wings 1344a and 1344b are formed at positions that almost overlap the circumferential centers of the engagement protrusions 1342a and 1342b, respectively, when viewed in the axial direction from the cleaning liquid tube side.

[0041] Next, the overall configuration of the cleaning unit 10 in which the above-mentioned main body 11, cover member 12, cleaning liquid tube connecting member 13, and elastic ring 14 are assembled will be described.

[0042] The wall 1112 of the connector mounting portion 111 is inserted into the groove 1223 of the cover member 12. At this time, since the engagement protrusions 1112d and 1112e of the connector mounting portion 111 have inclined surfaces that expand from the opening 1111 side, the wall 1112 is pushed into the groove 1223, and the outer wall 1221 of the cover member 12 is elastically deformed toward the outer diameter side. Furthermore, when the wall 1112 is pushed until it abuts against the bottom of the groove 1223, the engagement protrusions 1112d and 1112e are respectively fitted into the holes 1221a and 1221b provided in the outer wall 1221 of the cover member 12. The engagement protrusions 1112d and 1112e have a larger amount of protrusion toward the outer diameter side from the opening 1111 toward the opposite side in the axial direction. Therefore, even when the male connector 100 is pulled out of the insertion hole 121a, the engaging projections 112d and 112e engage with the holes 1221a and 1221b against the axial movement of the cover member 12, thereby functioning as a retainer for the cover member 12. The main body 11 and the cover member 12 are constructed as disposable members. The body 11 and the cover member 12 are provided to the practitioner in a pre-assembled state. Alternatively, the practitioner may assemble the body 11 and the cover member 12 by himself / herself.

[0043] The practitioner inserts the cleaning liquid tube connecting member 13, with the elastic ring 14 previously fitted in the groove 1441, into the connecting member mounting portion 113 of the main body 11 from the side of the tip portion 134 having the end face 133. The inner diameter of the small diameter portion 1133 of the connecting member mounting portion 113 of the main body 11 is set to be slightly larger than the outer diameter of the tip portion 134 of the cleaning liquid tube connecting member 13, and the portion from the end face 133 of the cleaning liquid tube connecting member 13 to the groove 1441 in which the elastic ring 14 is fitted is fitted into the small diameter portion 1133.

[0044] When the cleaning liquid tube connecting member 13 is inserted into the connecting member mounting portion 113, the engaging projections 1342a and 1342b are inserted from the sectorial portions 1132a2 and 1132a3 of the opening 1131a of the connecting member mounting portion 113. When the tip portion 134 of the cleaning liquid tube connecting member 13 is inserted to a predetermined position, circumferential grooves 1131b2 and 1131b3 are provided continuously at positions of the connecting member mounting portion 113 corresponding to the engaging protrusions 1342a and 1342b. Therefore, by rotating the cleaning liquid tube connecting member 13 clockwise relative to the main body portion 11 when viewed from the cleaning liquid tube side, the approximately wedge-shaped engaging protrusions 1342a and 1342b engage with the grooves 1131b2 and 1131b3, and the engaging protrusions 1342a and 1342b engage with the grooves 1131b2 and 1131b3 more securely, thereby functioning as an axial stopper for the cleaning liquid tube connecting member 13 relative to the main body portion 11. In addition, the cleaning liquid tube connecting member 13 is provided with wings 1344a and 1344b protruding toward the outer diameter side, so that the cleaning liquid tube connecting member 13 can be easily rotated by hooking fingers on the wings 1344a and 1344b. When the tip portion 134 of the cleaning liquid tube connecting member 13 is inserted to a predetermined position, the flange portion 1343 comes into contact with the end face 1113e of the small diameter portion 1133 of the connecting member mounting portion 113, thereby restricting axial movement toward the connector mounting portion 111 side.

[0045] The male connector 100 is attached to the cleaning unit 10 configured as described above. The male connector 100 is inserted from the tip side into the insertion hole 121a of the cover member 12. At least a portion of the cover member 12 including the insertion hole 121a is formed of an elastic material, so that the insertion hole 121a expands in diameter due to elastic deformation according to the shape of the male connector 100 to be inserted. The male connector 100 is further inserted into the connector attachment portion 111 in the axial direction, and the protrusion portion 1113c is fitted into the flow path 101a of the male connector 100. The male connector 100 is pushed into the connector attachment portion 111 until the end of the coupler 103 abuts against the end face 1113a on the small diameter portion 1112d side of the bulkhead 1113 of the connector attachment portion 111.

[0046] A cleaning liquid is pressure-fed from a pump or the like to the male connector 100 attached to the cleaning unit 10 through a tube inserted into the large diameter portion 131a of the cleaning liquid tube connecting member 13. The cleaning liquid supplied from the tube passes through a flow path formed by the hollow interior 131 in the cleaning liquid tube connecting member 13, and flows from the expanded diameter portion 131d into the cleaning liquid inlet hole of the main body 11. The cleaning liquid flowing in from the cleaning liquid inlet hole passes through a flow path in the partition wall 1113 and is ejected from the cleaning liquid ejection holes 1113d1-1113d4. The cleaning liquid ejected from the cleaning liquid ejection holes 1113d1-1113d4 flows into the internal space 100b of the male connector 100. The cleaning liquid flowing through this internal space 100b cleans the side of the connector body 101, the inner surface of the coupler 103, and the connector coupling portion 100a, and is introduced into the cleaning liquid discharge path 112a through the second cleaning liquid discharge hole 112c and discharged from the drainage tube portion 112.

[0047] In addition, in the connector coupling portion 100a, there is a possibility that the cleaning liquid may leak out to the upper side of FIG. 6 from the gap between the main body coupling portion 101c and the coupler coupling portion 103b. However, the leaked cleaning liquid falls between the inner peripheral surface of the inner wall portion 1222 of the cover member 12 and the inner peripheral surface of the small diameter portion 1112d of the main body portion 11 and the outer peripheral surface of the coupler 103, and is guided to the cleaning liquid discharge path 112a from the first cleaning liquid discharge hole 112b. The liquid is then discharged from the drain tube portion 112.

[0048] (Modification) In the above-mentioned embodiment 1, the end surface 121 of the cover member 12 is provided with the insertion hole 121a. The configuration of the portion through which the male connector 100 is inserted is not limited to this. As shown in FIG. 7(A), the male connector 100 may be inserted through a slit 121b provided in the end surface 121 of the cover member 12. The movable piece 121c defined by the slit 121b is elastically deformed, so that an opening for inserting the male connector 100 is easily formed, and resistance when inserting the male connector 100 is small. Then, the movable piece 121c is elastically restored according to the outer shape of the male connector 100 attached at a predetermined position, so that the opening becomes small. Here, the shape and number of the slits 121b can be appropriately selected. For example, as shown in FIG. 7(A), the slits 121b extending radially through the center of the end surface 121 of the cover member 12 may be arranged at 45° intervals in the circumferential direction. 7(B), a slit 121d may be formed extending radially outward from an insertion hole 121a provided in the center of the end face 121 of the cover member 12. Compared to the case where only the insertion hole 121a is provided, the movable piece 121e of the end face 121 is easily deformed when the male connector 100 is inserted, and there is less resistance during insertion. This modification can be applied not only to the first embodiment but also to the second embodiment described later.

[0049] <Example 2> Next, a description will be given of a cleaning unit 20 according to a second embodiment of the present invention. The same components as those in the cleaning unit 10 according to the first embodiment will be given the same reference numerals and detailed description will be omitted.

[0050] FIG. 8 shows an overall perspective view of the cleaning unit 20. FIG. 9 shows a front view (FIG. 9(A)), a right side view (FIG. 9(B)), a rear view (FIG. 9(C)), a plan view (FIG. 9(D)), and a bottom view (FIG. 9(E)) of the cleaning unit 20. FIG. 10(A) shows an exploded rear view of the cleaning unit 20, FIG. 10(B) shows an exploded right side view of the cleaning unit 20, and FIG. 10(C) shows an exploded BB cross-sectional view of the cleaning unit 10. FIG. 11 shows an exploded perspective view of the cleaning unit 20 as seen from the front right side. FIG. 12(A) shows a BB cross-sectional view of the cleaning unit 20, and FIG. 12(B) shows a CC cross-sectional view of the cleaning unit 20. In FIG. 12(A), the dashed line Ax2 indicates the axial direction of the cleaning unit 20.

[0051] The cleaning unit 20 is mainly composed of a substantially cylindrical main body 21, a cover member 12, and a cleaning liquid tube connecting member 23. The cleaning unit 20 corresponds to the connector cleaner of the present invention.

[0052] The configuration of the cover member 12 in this embodiment is the same as that in embodiment 1. The configurations of the connector mounting portion 111 and the drainage tube portion 112 of the main body portion 21 in this embodiment are also the same as those in embodiment 1. The configurations of the connection member mounting portion 213 and the cleaning liquid tube connecting member 23 of the main body portion 21 in this embodiment are different from those in embodiment 1. In this embodiment as well, the main body portion 21 may be formed of a hard member and have a disposable configuration that is intended to be replaced after one or more cleanings.

[0053] In the cleaning section according to this embodiment, a check valve 25 for preventing backflow of waste liquid after cleaning is provided in a flow path through which the cleaning liquid supplied from the cleaning liquid tube flows before being sprayed from the cleaning liquid spray holes 1113d1-1113d4 of the main body 21 via the cleaning liquid tube connecting member 23. In this embodiment, a tube-shaped check valve 25 made of a flexible member is disposed in the flow path from the cleaning liquid tube connecting member 23 to the cleaning liquid inlet hole that opens in the end face 1113e of the small diameter portion 2133 of the connection member mounting portion 213. The cleaning liquid tube connecting member 23 corresponds to the transport member connecting portion of the present invention.

[0054] 10(A) to (C), the cleaning liquid tube connecting member 23 is substantially cylindrical with a bottom. The hollow interior 231 of the cleaning liquid tube connecting member 23 has a large diameter The cleaning liquid tube connecting member 23 includes a portion 231a, a reduced diameter portion 231b that is continuous with the large diameter portion 231a and reduces in diameter toward the main body portion 21, and a small diameter portion 231c that is continuous with the reduced diameter portion 231b. The small diameter portion 231c has a closed end on the side of a tip portion 233 that is connected to the main body portion 21, and is provided with cleaning liquid outlet holes 231d1 and 231d2 that penetrate the side wall of the small diameter portion 231c. The cleaning liquid outlet holes 231d1 and 231d2 are opened at positions symmetrical with respect to the axis of the cleaning liquid tube connecting member 23.

[0055] The outer circumferential surface of the cleaning liquid tube connecting member 23 is provided with a large diameter portion 236 from a tip portion 234 where the cleaning liquid outlet holes 231d1 and 231d2 are opened toward the cleaning liquid tube side via a step portion 235. A groove 2361 that is recessed on the inner diameter side is formed over the entire circumference of the large diameter portion 236 in order to mount the elastic ring 14. The outer diameter of the large diameter portion 236 is slightly smaller than the inner diameter of a small diameter portion 2133 of the connecting member mounting portion 213 described later, and is set so that the elastic ring 14 mounted in the groove 2361 is pressed against the inner circumferential surface of the small diameter portion 2133. Engagement protrusions 2362a and 2362b that engage with the main body portion 21 are formed on the cleaning liquid tube side of the groove 2361. The engagement projection 2362a has a rib portion 2362a1 that extends over a portion of the circumferential direction and protrudes to the outer diameter portion, and a locking portion 2362a2 whose counterclockwise end as viewed from the cleaning liquid tube side is bent and extends toward the cleaning liquid tube side (the engagement projection 2362b has a similar configuration). The engagement projections 2362a and 2362b are arranged rotationally symmetrical with respect to the axis of the cleaning liquid tube connection member 23. On the outer circumferential surface of the cleaning liquid tube connection member 23, ribs 2363 that extend along the axial direction and protrude in the outer diameter direction are provided at equal intervals in the circumferential direction on the cleaning liquid tube side of the engagement projections 2362a and 2362b. The ribs 2363 are provided to reliably and easily grip the cleaning liquid tube connection member 23 when inserting the cleaning liquid tube into the hollow interior 231.

[0056] The check valve 25 is a cylindrical member made of a flexible material as described above. The inner diameter of the check valve 25 is set to be slightly smaller than the outer diameter of the tip 234 of the cleaning liquid tube connecting member 23 where the cleaning liquid outlet holes 231d1 and 231d2 are opened, and the check valve 25 attached to the outer periphery of the tip 234 is pressed against the outer periphery of the tip 234. When the cleaning liquid pressure-fed from the cleaning liquid tube flows out from the cleaning liquid outlet holes 231d1 and 231d2, it deforms the check valve 25 and flows out to the main body 21 side through the gap between the outer periphery of the tip 234 of the cleaning liquid tube connecting member 23 and the check valve 25. By providing the check valve 25 in this way, it is possible to prevent the cleaning liquid contaminated by cleaning the male connector 100 from flowing back from the cleaning liquid outlet holes 231d1 and 231d2, so that each part upstream of the cleaning liquid outlet holes 231d1 and 231d2 can be contaminated. In addition, since the check valve 25 is a cylindrical flexible member that covers the cleaning liquid outlet holes 231d1 and 231d2, the forward flow of the cleaning liquid can be easily adjusted by setting the size of the cleaning liquid outlet holes 231d1 and 231d2 and the material and size of the check valve 25.

[0057] The configuration of the connection member mounting portion 213 of the main body 21 according to this embodiment will be described. The connection member mounting portion 213 is provided on the opposite side of the connector mounting portion 111 in the axial direction, similar to the main body 11 according to the first embodiment. The connection member mounting portion 213 has a large diameter portion 2131 including an opening 2131a into which the cleaning liquid tube connecting member 23 is inserted, and a small diameter portion 2133 continuing to the large diameter portion 2131 via a step portion 2132. Holes 2131c2 and 2131c3 extending in the circumferential direction are provided in the side wall of the large diameter portion 2131 on the step portion 2132 side, penetrating the side wall from the inner peripheral side to the outer peripheral side. The holes 2131c2 and 2131c3 have shapes that are rotationally symmetrical to each other with respect to the axis. On the inner peripheral surface of the large diameter portion 2131, flange portions 2131b2 and 2131b3 are formed which protrude inward from the edges of the holes 2131c2 and 2131c3 on the opening 2131a side to the end face of the opening 2131a. The circumferential length of the flange portions 2131b2 and 2131b3 is substantially the same as the circumferential length of the holes 2131c2 and 2131c3. As shown in FIG. 9(E), the flange portions 2131b2 and 2131b3 are The electrodes are arranged so as to be rotationally symmetrical with respect to each other.

[0058] When the cleaning liquid tube connecting member 23 equipped with the check valve 25 and the elastic ring 14 is attached to the connecting member attaching portion 213 of the main body 21, the tip portion 234 is inserted into the small diameter portion 2133 from the opening 2131a. The elastic ring 14 attached to the groove 2361 is pressed against the inner circumferential surface of the small diameter portion 2133 and deformed, thereby keeping the small diameter portion 2133 and the tip portion 234 liquid-tight with the cleaning liquid tube side. When the tip portion 234 is inserted from the opening 2131a, the engaging protrusions 2362a and 2362b pass through the area between the flange portions 2131b2 and 2131b3 in the circumferential direction so that the engaging protrusions 2362a and 2362b do not interfere with the flange portions 2131b2 and 2131b3. When the tip portion 234 is inserted to a predetermined position in the connection member attachment portion 213, the engaging protrusions 2362a and 2362b reach a position in the axial direction that is closer to the small diameter portion 2133 than the flange portions 2131b2 and 2131b3. In this manner, with the engaging protrusions 2362a and 2362b reaching positions beyond the flange portions 2131b2 and 2131b3, the cleaning liquid tube connecting member 23 is rotated clockwise as viewed from the cleaning liquid tube side until the locking portions 2362a2 and 2362b2 abut against the ends of the flange portions 2131b2 and 2131b3, respectively. As the locking portions 2362a2 and 2362b2 abut the ends of the flange portions 2131b2 and 2131b3, clockwise rotation is restricted when viewed from the cleaning liquid tube side, and as viewed from the cleaning liquid tube side, the rib portions 2362a1 and 2362b1 of the engagement protrusions 2362a and 2362b overlap with the flange portions 2131b2 and 2131b3, thereby restricting movement of the cleaning liquid tube connecting member 23 toward the cleaning liquid tube side and functioning as a stopper.

[0059] The attachment of the male connector 100 to the cleaning unit 20 is the same as in the first embodiment, and therefore a description thereof will be omitted. In addition, with respect to the cover member 12 of the cleaning section 20 in Example 2, a slit 121b may be provided instead of the insertion hole 121a as shown in Figure 7(A), or a slit 121d may be provided in addition to the insertion hole 121a as shown in Figure 7(B).

[0060] (Modification) In this embodiment, a tube-shaped check valve made of a flexible member has been described, but the configuration of the check valve 25 provided in the cleaning unit is not limited to this. For example, a known type of check valve such as a duckbill type, an umbrella type, a disk type, or a ball type can be adopted. In addition, the position where the check valve is provided is not limited to the tip 234 of the cleaning liquid tube connecting member 23 as in this embodiment, but a check valve that prevents backflow of the drained liquid after cleaning can be provided at any position of the flow path through which the cleaning liquid flows before being supplied to the cleaning liquid tube connecting member 23 and ejected from the cleaning liquid ejection holes 1113d1 to 1113d4 of the main body 21. In addition, in conjunction with the placement of the check valve, a holding means for holding the check valve or a part thereof may be provided on either or both of the main body 21 side and the cleaning liquid tube connecting member 23 side of the cleaning unit 20.

[0061] <Example 3> Third Embodiment Next, a cleaning unit 30 according to a third embodiment of the present invention will be described. FIG. 13 shows an overall perspective view of the cleaning unit 30 with the lid member 32 open. FIG. 14 shows a plan view (FIG. 14(A)), a bottom view (FIG. 14(B)), a front view (FIG. 14(C)), a right side view (FIG. 14(D)), and a rear view (FIG. 14(E)) of the cleaning unit 30 with the lid member 32 open. FIG. 15(A) shows a DD cross-sectional view of the cleaning unit 30 with the lid member 32 open, and FIG. 15(B) shows an EE cross-sectional view of the cleaning unit 30. FIG. 16 shows an overall perspective view of the cleaning unit 30 with the lid member 32 closed. FIG. 17 shows a plan view (FIG. 17(A)), a bottom view (FIG. 17(B)), a front view (FIG. 17(C)), a right side view (FIG. 17(D)), and a rear view (FIG. 17(E)) of the cleaning unit 30 with the lid member 32 closed. Fig. 18(A) is a cross-sectional view taken along the line FF when the cover member 32 of the cleaning unit 30 is closed, and Fig. 18(B) is an enlarged cross-sectional view taken along the line FF of the cleaning unit 30. Ax3 indicates the axial direction of the cleaning unit 30.

[0062] The cleaning unit 30 according to this embodiment is mainly composed of a substantially cylindrical main body 31, a cover member 32, and a cleaning liquid tube connecting member 33. The cleaning unit 30 opens and closes an opening 41 for attaching a male connector 100 by operating the scissor-shaped cover member 32. The cleaning unit 30 corresponds to the connector cleaner of the present invention. In this embodiment, the main body 31 may also be disposable and is assumed to be replaced after one or more cleanings, and the main body 31 is assembled to the scissor-shaped cover member 32 and the cleaning liquid tube connecting member 33 by the practitioner. The main body 31 may be assembled to the scissor-shaped cover member 32 and the cleaning liquid tube connecting member 33 in advance.

[0063] The main body 31 is mainly provided with a connector mounting portion 311, a drainage tube portion 312, and a connection member receiving portion 313 in the axial direction. The connector mounting portion 311 is substantially cylindrical with a bottom having an opening 3111 at one end in the axial direction, and has a substantially columnar hollow interior for accommodating the male connector 100. The connector mounting portion 311 is defined by a substantially cylindrical side wall portion 3112 and a bottom surface 3113a constituted by a partition wall 3113 that separates the opening 3111 and the connection member receiving portion 313 at the end opposite the axial direction. The bottom surface 3113a is provided with a groove 3113b that is annular in plan view and can accommodate the tip of the connector main body 101 when the male connector 100 is attached. In addition, a cylindrical protrusion 3113c that is inserted into the flow path 101a of the connector main body 101 is formed on the center side of the inner circumference of the groove 3113b. The protrusion 3113c forms a separating portion that separates the flow path 101a of the connector body 101 from the flow path of the cleaning liquid. When the male connector 100 is attached to the connector attachment portion 311, the tip of the coupler 103 abuts against the bottom surface 3113a on the outer circumferential side of the groove 3113b. The bottom surface 3113a on which the tip of the coupler 103 abuts is provided with a groove 3113d for mounting an elastic ring 3114, and the tip of the coupler 103 abuts against the elastic ring 3114. This makes it possible to support the male connector 100 elastically so that it can move up and down. The connector attachment portion 311 corresponds to the storage portion of the present invention.

[0064] Cleaning liquid ejection holes 3113e1-3113e4 (see FIG. 14(A)) serving as cleaning liquid ejection parts are arranged at equal intervals in the circumferential direction at the bottom of groove 3113b in bottom surface 3113a. These cleaning liquid ejection holes 3113e1-3113e4 communicate with a cleaning liquid inlet hole opening in end face 3113f of partition wall 3113 separating connector mounting part 311 and connection member receiving part 313 on the side of connection member receiving part 313, via an in-wall flow path. Cleaning liquid is pumped from the outside to the cleaning liquid inlet hole, whereby cleaning liquid is ejected from cleaning liquid ejection holes 3113e1-3113e4.

[0065] A first cleaning liquid discharge hole 312b communicating with a cleaning liquid discharge path 312a penetrating the inside of the drain tube part 312 is opened at the end part on the bottom surface 3113a side of the side wall part 3112 of the connector attachment part 311, and a second cleaning liquid discharge hole 312c similarly communicating with the cleaning liquid discharge path 312a is opened in the side wall of the groove 3113b. The cleaning liquid discharge path 312a corresponds to the discharge part of the present invention.

[0066] The connection member receiving portion 313 is provided on the main body 31 on the opposite side to the connector mounting portion 311 in the axial direction. The connection member receiving portion 313 is cylindrical with a bottom. One axial end of the connection member receiving portion 313 is an end face 3113f formed by the partition wall 3113, and the other end is an opening 3131. A cleaning liquid inlet hole communicating with the cleaning liquid ejection holes 3113e1 to 3113e4 through the inside of the partition wall 3113 is opened in the end face 3113f. In addition, flange portions 3132a and 3132b protruding toward the outer diameter side are formed at the end on the opening 3131 side. The flange portions 3132a and 3132b extend over a part of the circumferential direction, the flange portion 3132a is formed in the direction in which the drainage tube portion 312 protrudes, and the flange portion 3132b is formed at a position rotationally symmetrical to the flange portion 3132a with respect to the axis.

[0067] The cleaning liquid tube connecting member 33 has a tube connecting part 331 having a substantially cylindrical shape with a bottom, a main body support part 332 that supports the end part of the main body part 31 on the cleaning liquid tube side and the back side, and a lid member support part 333 that supports the lid member 32 (see FIG. 16). The cleaning liquid tube connecting member corresponds to the transport member connecting part of the present invention.

[0068] The main body support part 332 includes an end support part 3321 that supports the end part of the main body part 31 on the cleaning liquid tube side, and a back support part 3322 that supports the end part on the back side of the main body part 31, and the tube connection part 331 is provided integrally with the end support part 3321. The hollow interior 3312 of the tube connection part 331 includes a large diameter part 3312a into which the cleaning liquid tube is inserted, a reduced diameter part 3312b that is continuous with the large diameter part 3312a and reduces in diameter toward the main body part 31 side, and a small diameter part 3312c that is continuous with the reduced diameter part 3312b. The small diameter part 3312c is closed on the side of the tip part 3313 that is connected to the main body part 31, and cleaning liquid outlet holes 3312d1 and 3312d2 that penetrate the side wall of the small diameter part 3312c are provided. The cleaning liquid outlet holes 3312d1 and 3312d2 are opened at positions symmetrical with respect to the axis of the cleaning liquid tube connecting member 33. On the outer circumferential surface 3314 of the tube connecting part 331, a large diameter part 33141 is formed on the outer circumferential side of the large diameter part 3312a of the hollow interior 3312, and a small diameter part 33142 is formed on the outer circumferential side of the small diameter part 3312c of the hollow interior 3312. On the outer circumferential side of the reduced diameter part 3312b, a substantially bottomed cylindrical end support part 3321 protruding in the outer diameter direction is integrally formed between the large diameter part 33141 and the small diameter part 33142. A cylindrical check valve made of a flexible member may be attached to the outer circumferential side of the tip part 3313 of the cleaning liquid tube connecting member 33 so as to cover the cleaning liquid outlet holes 3312d1 and 3312d2.

[0069] The end support portion 3321 includes a disk-shaped bottom portion 33211 connected to the outer peripheral surface of the tube connection portion 331, and a tubular portion 33212 extending from the outer peripheral end of the bottom portion 33211 all around toward the male connector 100 in the axial direction. A recessed groove 33211a for mounting the elastic ring 334 is formed all around on the main body portion 31 side of the bottom portion 33211. Grooves 33212a and 33212b into which flange portions 3132a and 3132b formed on the connection member receiving portion 313 of the main body portion 31 are fitted are formed on the inner peripheral surface of the tubular portion 33212 on the bottom portion 33211 side. The grooves 33212a and 33212b are provided at positions rotationally symmetrical with respect to the axis. Then, notches 33213a and 33213b are formed by cutting out the counterclockwise ends of the side walls of the grooves 33212a and 33212b on the side of the main body 31 when viewed from the main body side. The notches 33213a and 33213b are formed to a size that allows the flanges 3132a and 3132b to enter the grooves 33212a and 33212b when the main body 31 is attached to the end support part 3321 in the axial direction. When the main body 31, which has been inserted from the notches 33213a and 33213b into the grooves 33212a and 33212b, is rotated clockwise toward the cleaning liquid tube, the flanges 3132a and 3132b move from the notches 33213a and 33213b to the grooves 33212a and 33212b having side walls, and are fitted into the grooves 33212a and 33212b, thereby restricting their movement in the axial direction. In this way, the axial movement of the flanges 3132a and 3132b, which are arranged rotationally symmetrical with respect to the axis, is restricted from both sides by the grooves, so that the main body 31 is reliably supported by the end support 3321 in an upright position along the axial direction.

[0070] In the main body support part 332, a part of the circumferential direction of the tube part 33212 of the end support part 3321 is continuous with the back support part 3322 extending in the axial direction. The back support part 3322 is in the shape of a plate curved around the axis of the main body part 31. The back support part 3322 includes a small diameter part 3322a continuing with the end support part 3321, an enlarged diameter part 3322b continuing with the male connector 100 side along the axial direction of the small diameter part 3322a and bending toward the outer diameter side, and a large diameter part 3322c continuing with the male connector 100 side along the axial direction of the enlarged diameter part 3322b and extending in the axial direction. When the main body part 31 is attached to the main body support part 332, the inner peripheral surface of the enlarged diameter part 3322b of the back support part 3322 abuts on the outer peripheral surface of the enlarged diameter part 31a of the main body part 31, and the large diameter part 3322c of the back support part 3322 abuts on the outer peripheral surface of the enlarged diameter part 31a of the main body part 31. The inner circumferential surface abuts against the outer circumferential surface of the large diameter portion 31b of the main body 31, thereby supporting the rear side of the main body 31.

[0071] A lid member support part 333 extending in the outer diameter direction is provided at the end of the back support part 3322 on the male connector 100 side. The lid member support part 333 is generally plate-shaped with a support surface 3331 which is a wide surface perpendicular to the axial direction, and a shaft support hole 3332 through which the rotation shaft of the lid member 32 is inserted is formed in the center of the support surface 3331. A tapered part 3332a which reduces in diameter toward the shaft support hole 3332 is formed around the entire circumference at the edge of the shaft support hole 3332 of the support surface 3331. In addition, a wall part 3333 extending in a direction perpendicular to the support surface 3331 is formed at the outer edge of the support surface 3331 on the cleaning liquid tube side.

[0072] The cover member 32 includes a first cover member 321 and a second cover member 322. The first cover member 321 is supported rotatably about a rotation axis Ax4 by a shaft portion 3211 inserted into a shaft support hole 3332 provided in the cover member support portion 333. The rotation axis Ax4 is provided parallel to an axial direction Ax3 of the connector attachment portion 311 that coincides with the axial direction of the male connector 100. The first cover member 321 is a substantially plate-shaped member having an annular operation portion 3212 for insertion of a finger for operation on one side in a direction perpendicular to the rotation axis Ax4, and an opening / closing portion 3213 for opening and closing an opening 3111 of the connector attachment portion 311 on the other side. The second cover member 322 is a generally plate-shaped member having, on one side of an axial hole 3221 through which the axial portion 3211 is inserted, a ring-shaped operating portion 3222 for inserting a finger therethrough to operate, and, on the other side of the axial hole 3221, an opening / closing portion 3223 for opening and closing the opening 3111 of the connector mounting portion 311.

[0073] The shaft portion 3211 of the first cover member 321 is cylindrical and protrudes from one surface of the first cover member 321, which is generally plate-like, in a direction perpendicular to the surface. A flange 3211b protruding in the outward direction is formed around the entire circumference of the outer periphery of the tip portion 3211a of the shaft portion 3211. The outer periphery of the flange 3211b is a tapered portion whose diameter decreases toward the tip side. As described above, the shaft portion 3211 of the first cover member 321 is inserted into the shaft hole 3221 of the second cover member 322 and into the shaft support hole 3332 of the cover member support portion 333. At this time, by rubbing the tapered portion of flange 3211b at the tip of shaft portion 3211 against tapered portion 3332a around shaft support hole 3332, at least one of flange 3211b of first cover member 321 or shaft support hole 3332 of cover member support portion 333 is elastically deformed, and shaft portion 3211 is guided into shaft support hole 3332, and first cover member 321 and second cover member 322 can be easily attached to cover member support portion 333. In addition, by engaging flange 3211b provided on shaft portion 3211 with the edge of shaft support hole 3332, first cover member 321 and second cover member 322 are prevented from coming off and can be supported rotatably around shaft portion 3211.

[0074] The opening / closing part 3213 of the first cover member 321 is roughly shaped like a bottomed tube divided into two by a diametrical surface passing through the central axis. The inner peripheral surface of the opening / closing part 3213 has a large diameter part 32131 that abuts against half the circumference of the end of the side wall part 3112 of the connector attachment part 311 on the opening 3111 side, and a small diameter part 32132 that covers the opening 3111 of the connector attachment part 311 and abuts against half the circumference of the connector body 101 of the male connector 100 attached to the connector attachment part 311. The large diameter part 32131 has a protrusion 32131a that protrudes toward the inner diameter side and is formed over half the circumference, and this protrusion 32131a fits into a circumferential groove 3112a provided near the end of the side wall part 3112 of the connector attachment part 311 on the opening 3111 side when the first cover member 321 is closed. In addition, the end face of the small diameter portion 32132 opposite to the large diameter portion 32131 is tapered, and the inner diameter side end 32132a of the small diameter portion 32132 is formed so that the axial thickness becomes thinner toward the inner diameter side. As shown in FIG. 18(B), the inner diameter side end 32132a of the small diameter portion 32132 is positioned so that it enters the coupler 103 side portion of the groove 101g of the connector body 101 of the male connector 100 when the first cover member 321 is closed. Therefore, when the first cover member 321 is closed, the elastic ring attached in the groove 101g The inner diameter side end 32132a of the small diameter portion 32132 presses the portion of the elastic ring 104 on the coupler 103 side, and the elastic ring 104 can be pressed against the bottom 101f of the groove 101g and the rib portion 101e, thereby suppressing leakage of the cleaning liquid that has passed between the connector body 101 and the coupler 103. The same effect can be obtained by the inner diameter side end 32132a of the small diameter portion 32132 pressing the side of the elastic ring 104 opposite to the coupler 103, and pressing the elastic ring 104 against the bottom 101f of the groove 101g and the rib portion 101d.

[0075] The opening / closing part 3223 of the second cover member 322, like the opening / closing part 3213 of the first cover member 321, is roughly shaped like a bottomed tube divided into two by a diametrical surface passing through the central axis. The inner peripheral surface of the opening / closing part 3223 has a large diameter part 32231 that abuts against a half circumference of the end part on the opening 3111 side of the side wall part 3112 of the connector attachment part 311, and a small diameter part 32232 that covers the opening 3111 of the connector attachment part 311 and abuts against a half circumference of the connector main body 101 of the male connector 100 attached to the connector attachment part 311. The large diameter part 32231 has a protrusion 32231a that protrudes to the inner diameter side, like the large diameter part 32131 of the first cover member 321. Also, the small diameter part 32232 has an end part 32232a on the inner diameter side, like the small diameter part 32132 of the first cover member 321.

[0076] The circumferential end surface 3213c of the opening / closing portion 3213 of the first cover member 321, when the first cover member 321 is closed, substantially coincides with a surface extending in the radial direction and including the axis of the connector mounting portion 311. The circumferential end surface 3223c of the opening / closing portion 3223 of the second cover member 322, when the second cover member 322 is closed, also substantially coincides with a surface extending in the radial direction and including the axis of the connector mounting portion 311. In addition, a plate-shaped engagement portion 3213d extending in the circumferential direction toward the second cover member 322 is formed on the end of the end surface 3213c of the opening / closing portion 3213 of the first cover member 321 on the side opposite to the shaft portion 3211. An engagement protrusion 3213e extending in the axial direction and protruding toward the inner diameter side is provided on the inner diameter side of this engagement portion 3213d. On the other hand, the end of the opening / closing part 3223 of the second cover member 322 opposite to the axial hole 3221 is formed with a recess 3223d that is slightly recessed to the inner diameter to receive the engaging part 3213d of the first cover member 321 when the first cover member 321 and the second cover member 322 are closed, and an axial groove 3223e that engages with the engaging protrusion 3213e of the first cover member 321 is formed in the recess 3223d. Therefore, when the first cover member 321 and the second cover member 322 are closed, the engaging protrusion 3213f of the first cover member 321 engages with the groove 3223f of the second cover member 322, thereby restricting the movement of the first cover member 321 and the second cover member 322 in the opening direction. Engagement portion 3213d and engagement projection 3213e of first cover member 321 and recess 3223d and groove 3223e of second cover member 322 correspond to the restricting means of the present invention that restricts movement of first cover member 321 and second cover member 322 in a state in which opening portion 3111 is closed. This ensures that circumferential end surface 3213c of opening / closing portion 3213 of first cover member 321 and circumferential end surface 3223c of opening / closing portion 3223 of second cover member 322 come into reliable contact with each other.

[0077] First cover member 321 and second cover member 322 are disposed so as to intersect with each other centering on shaft portion 3211. That is, in a plan view, operation portion 3212 of first cover member 321 is located on the left side of main body portion 21 and opening / closing portion 3213 is located on the right side of main body portion 21, while operation portion 3222 of second cover member 322 is located on the right side of main body portion 21 and opening / closing portion 3223 is located on the left side of main body portion 21.

[0078] In the cleaning liquid tube connection member 33, a gripping portion consisting of an axial rib or a convex portion protruding in the outward direction can be provided on the outer peripheral surface of the cylindrical portion 33212 of the end support portion 3321 and the back support portion 3322 continuous with the cylindrical portion 33212. By providing such a gripping portion, the cleaning liquid tube connection member 33 with the main body portion 31 attached can be securely gripped with one hand. In this way, by securely gripping and stabilizing the cylindrical portion 33212 and the back support portion 3322, the operating portion 3212 of the first cover member 321 and the second cover member 32 can be gripped with the other hand. Therefore, there is no risk that one of first cover member 321 or second cover member 322 will not fully retract from opening 3111, leaving opening 3111 partially closed and thus preventing attachment or detachment of male connector 100.

[0079] In addition, as a means to prevent one of the first cover member 321 or the second cover member 322 from sufficiently retracting from the opening 3111, leaving the opening 3111 partially closed, which would hinder the attachment or removal of the male connector 100, a gear can be provided that links the rotational movements of the first cover member 321 and the second cover member 322 relative to the cover member support portion 333 centered on the shaft portion 3211. Furthermore, protrusions made of an elastic material can be provided between the side wall 3112 of the main body 31 and the opening / closing parts 3213 and 3223 so that the restoring force of the compressed protrusions acts when the first cover member 321 and the second cover member 322 are closed. By providing such protrusions, when the engagement between the engaging protrusion 3213e and the groove 3223e is released, the opening / closing parts 3213 and 3223 are sufficiently retracted from the opening 3111, and attachment or removal of the male connector 100 is not hindered.

[0080] In the cleaning unit 30, for example, the index finger and thumb are inserted into the operating portion 3212 of the first cover member 321 and the operating portion 3222 of the second cover member 322, respectively, and the fingers are spread apart, whereby the first cover member 321 and the second cover member 322 are opened as shown in Fig. 13. At this time, the opening / closing portion 3213 and the opening / closing portion 3223 move in a direction substantially perpendicular to the axial direction, i.e., in the outer radial direction, relative to the opening 3111. As a result, the entire opening 3111 is exposed. From the exposed opening 3111, the male connector 100 is inserted into the connector mounting part 311 along the axial direction from the tip side. By opening the first cover member 321 and the second cover member 322, the opening / closing parts 3213 and 3223 are retracted from the vicinity of the axial direction, which is the insertion direction of the male connector 100, to a direction substantially perpendicular to this axial direction with respect to the opening 3111. Depending on the positional relationship between the opening 3111 and the cover member, when mounting the male connector 100 to the connector mounting part 311, it may be necessary to insert the male connector 100 from a direction different from the orientation at the time of accommodation in order to avoid interference with the cover member. However, in this cleaning part 30, the axial direction of the male connector 100 and the axial direction of the cleaning part 30 may be aligned, and the male connector 100 can be easily mounted and accommodated in the cleaning part 30. In addition, after the male connector 100 is attached to a predetermined position in the cleaning section 30, the opening / closing section 3213 and the opening / closing section 3223 can be closed and the opening 3111 can be covered simply by narrowing the gap between the fingers inserted into the operating section 3212 of the first cover member 321 and the operating section 3222 of the second cover member 322, thereby reducing the process of closing the cover member 32.

[0081] (Modification) Next, a cleaning unit 40 according to a modified example of the third embodiment will be described. Fig. 19(A) shows a plan view of the cleaning unit 40 in a state where the opening / closing parts 423 and 424 are open, and Fig. 19(B) shows a plan view of the cleaning unit 40 in a state where the opening / closing parts 423 and 424 are closed. The same components as those of the cleaning unit 30 according to the third embodiment are denoted by the same reference numerals and detailed description thereof will be omitted.

[0082] The cleaning unit 40 is composed of a substantially cylindrical main body 31, a cover member 42, and a cleaning liquid tube connecting member 43. The cleaning unit 40 corresponds to the connector cleaner of the present invention.

[0083] The cleaning liquid tube connecting member 43 has the same configuration as the cleaning liquid tube connecting member 33 according to the third embodiment, except for the configuration of the lid member supporting portion 433.

[0084] The cover member 42 is supported by a cover member support portion 433 of the cleaning liquid tube connection member 43 and has a substantially rectangular shape. The housing has a frame 421 and opening / closing sections 423 and 424 that are provided so as to be movable in a direction perpendicular to the axial direction of main body section 31 and male connector 100 attached to main body section 31 by a guide section provided on frame 421. Opening / closing section 423 corresponds to the first cover member of the present invention, and opening / closing section 424 corresponds to the second cover member of the present invention.

[0085] The opening / closing part 423 is roughly shaped like a bottomed tube divided into two parts by a diametrical surface passing through the central axis. The inner peripheral surface of the opening / closing part 423 has a large diameter part 32131 that abuts against half the circumference of the end part on the opening 3111 side of the side wall part 3112 of the connector mounting part 311, and a small diameter part 32132 that covers the opening 3111 of the connector mounting part 311 and abuts against half the circumference of the connector body 101 of the male connector 100 attached to the connector mounting part 311. The large diameter part 32131 has a protrusion 32131a that protrudes toward the inner diameter side and is formed over half the circumference, and this protrusion 32131a fits into a circumferential groove 3112a provided near the end part on the opening 3111 side of the side wall part 3112 of the connector mounting part 311 when the opening / closing part 423 is closed. In addition, the end face of the small diameter portion 32132 opposite to the large diameter portion 32131 is tapered, and the inner diameter side end 32132a of the small diameter portion 32132 is formed so that the thickness in the axial direction becomes thinner toward the inner diameter side. The inner diameter side end 32132a of the small diameter portion 32132 is arranged at a position where it enters the coupler 103 side part of the groove 101g of the connector main body 101 of the male connector 100 when the opening and closing part 423 is closed. Therefore, when the opening and closing part 423 is closed, the inner diameter side end 32132a of the small diameter portion 32132 presses the coupler 103 side part of the elastic ring attached to the groove 101g, and the elastic ring 104 can be pressed against the groove 101g, so that the leakage of the cleaning liquid that has passed between the connector main body 101 and the coupler 103 can be suppressed.

[0086] The opening / closing part 424, like the opening / closing part 423, has a shape of a bottomed tube divided into two by a surface in the diameter direction passing through the central axis. The inner peripheral surface of the opening / closing part 423 has a large diameter part 32231 that abuts against a half circumference of the end part on the opening 3111 side of the side wall part 3112 of the connector mounting part 311, and a small diameter part 32232 that covers the opening 3111 of the connector mounting part 311 and abuts against a half circumference of the connector main body 101 of the male connector 100 attached to the connector mounting part 311. The large diameter part 32231 has a protrusion 32231a that protrudes to the inner diameter side, like the large diameter part 32131 of the opening / closing part 423. Also, the small diameter part 32232 has an end part 32232a on the inner diameter side, like the small diameter part 32132 of the first cover member 321.

[0087] When the opening / closing part 423 is closed, the circumferential end face 3213c of the opening / closing part 423 approximately coincides with a plane extending in the diameter direction and including the central axis of the connector attachment part 311. When the opening / closing part 424 is closed, the circumferential end face 3223c of the opening / closing part 424 also approximately coincides with a plane extending in the diameter direction and including the axis of the connector attachment part 311.

[0088] 19(B), a restricting means is provided that restricts the movement of opening / closing parts 423 and 424 in the opening direction when opening / closing parts 423 and 424 are closed. This movement restricting means can be set so as to be released by applying a force of a predetermined value or more in the opening direction to opening / closing parts 423 and 424. The configuration of the restricting means capable of releasing opening / closing parts 423 and 424 is not limited to this.

[0089] In addition, a gear may be provided to link the opening and closing operations of the opening / closing sections 423 and 424, or a protrusion made of an elastic material that is compressed when the opening / closing sections 423 and 424 are closed may be provided between the side wall portion 3112 of the main body portion 31 and the opening / closing sections 423 and 424.

[0090] (Cleaning System) FIG. 20 shows a cleaning system 70 in which the cleaning unit 10, 20 or 30, a pressure pump 72, a cleaning liquid tank 71 and a drain tank 75 are simply illustrated. In this example, the cleaning units 10, 20 and 30 and the cleaning liquid tank 71 are connected to a cleaning liquid tube. The cleaning liquid tank 71 is connected to the tube connecting members 13, 23 and 33 through a flexible cleaning liquid tube 73. The cleaning liquid tube 73 is exposed from the cleaning liquid tank 71, and the cleaning unit 10, 20 or 30 can be freely moved. The cleaning liquid tube 73 is preferably about 300 mm to 2000 mm long, more preferably about 800 to 1800 mm long. When the cleaning liquid tube 73 is long, a holder for assembling the cleaning unit 10, 20 or 30 to a cleaning system having a pump may be provided. The cleaning liquid tank 71 is provided with a pressure pump 72 for pressure-feeding the cleaning liquid stored in the cleaning liquid tank 71 to the cleaning liquid tube connecting members 13, 23 or 33. The cleaning liquid tank 71 and the pressure pump 72 may be separable or inseparable.

[0091] In addition, a flexible discharge tube 74 is provided which communicates the cleaning liquid discharge paths 112a and 312a with the drain tank 75 and guides the cleaning liquid discharged from the cleaning liquid discharge path 112a or 312a to the drain tank 75. The discharge tube 74 is exposed to the outside from the drain tank 75, reducing the occurrence of problems with the operation of the cleaning unit 10, 20 or 30. In this example, by operating the pressure pump 72, the cleaning liquid is sprayed into the internal space 100b of the male connector 100 to clean the internal space 100b, and the cleaning liquid after cleaning can be discharged into the drain tank 75 and temporarily stored therein.

[0092] This makes it possible to configure a cleaning system 70 in which the cleaning liquid tank 71 and the drainage tank 75 are stationary and the cleaning unit 10, 20, or 30 can be freely moved relative to them. As a result, the male connector 100 can be cleaned by moving only the cleaning unit 10, 20, or 30 to a place where cleaning work can be easily performed, making it possible to perform the cleaning work more easily or more efficiently. It is also possible to provide either the pressure pump or the cleaning liquid tank in the cleaning unit 10, 20, or 30. In FIG. 19, the cleaning liquid tank 71 and the drainage tank 75 are configured separately, but it is also possible to provide a mounting table on which the cleaning liquid tank 71 and the drainage tank 75 can be placed, and the cleaning liquid tank 71 and the drainage tank 75 can be placed on the mounting table, or the pressure pump, the cleaning liquid tank, and the cleaning liquid tank can be integrated.
