Description

The present invention relates to a connector washer that cleans a connector for connecting a medical tube.

Conventionally, efforts have been made to prevent erroneous connection of connectors for connecting medical tubes. As part of such efforts, the promotion of medical accident prevention and the introduction of standards for stable supply through international harmonization are being promoted. For enteral nutrition, there is a standard that the connector on the side connected to the patient is on the male side and the connector on the opposite side to the patient is on the female side. In such a standard, structurally, for example, a nutritional supplement 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 causing hygienic inconveniences such as bacterial growth in the male connector indwelled while connected to the patient. In order to eliminate such a danger, a technique of wiping with a member that absorbs the nutrient is disclosed, but the nutrient may not be completely wiped off and may solidify.

Engagement protrusions 1342a and 1342b that engage with the main body 11 are formed on the outer peripheral surface of the tip 134 of the cleaning liquid tube connecting member 13 on the opposite side of the groove 1341 from the main body 11. The engaging protrusions 1342a and 1342b have a plate shape that extends over a part in the circumferential direction and protrudes toward the outer diameter side. The axial thicknesses of the engaging protrusions 1342a and 1342b are formed so as to be smaller clockwise when viewed from the cleaning liquid tube side, and the engaging protrusions 1342a and 1342b are substantially wedge-shaped when viewed from the outer diameter side. .. Further, the engaging protrusions 1342a and 1342b are arranged rotationally symmetrically with respect to the axis of the cleaning liquid tube connecting member 13.

A disk-shaped flange portion 1343 is formed on the cleaning liquid tube side of the engaging protrusions 1342a and 1342b of the cleaning liquid tube connecting member 13 so as to project toward the outer diameter side over the entire circumference. Further, on the outer peripheral surface of the cleaning liquid tube connecting member 13, a plate-shaped wing extending along the axial direction from the end surface of the flange portion 1343 on the cleaning liquid tube side and projecting to the outer diameter side. The portions 1344a and 1344b are formed. The blade portions 1344a and 1344b are provided to securely and easily grip the cleaning liquid tube connecting member 13 when the cleaning liquid tube is inserted into the hollow inner 131. The wing portions 1344a and 1344b are formed at positions substantially overlapping the central portions in the circumferential direction of the engaging protrusions 1342a and 1342b, respectively, when viewed along the axial direction from the cleaning liquid tube side.

Next, the overall configuration of the cleaning unit 10 to which the main body portion 11, the lid member 12, the cleaning liquid tube connecting member 13, and the elastic ring 14 are assembled will be described.

The wall portion 1112 of the connector mounting portion 111 is inserted into the groove 1223 of the lid member 12. At this time, since the engaging protrusions 1112d and 1112e of the connector mounting portion 111 are formed with slopes whose diameter is expanded from the opening 1111 side, the wall portion 1112 is pushed into the groove 1223 to form an outer wall portion of the lid member 12. The 1221 is elastically deformed to the outer diameter side. Further, when the wall portion 1112 is pushed in until it comes into contact with the bottom portion of the groove 1223, the engaging protrusions 1112d and 1112e are fitted into the holes 1221a and 1221b provided in the outer wall portion 1221 of the lid member 12, respectively. The engaging protrusions 1112d and 112e have a large protrusion amount toward the outer diameter side from the opening 1111 to the opposite side in the axial direction. Therefore, even when the male connector 100 is pulled out from the insertion hole 121a, the engaging protrusions 1112d and 112e are formed on the lid member 12 by engaging with the holes 1221a and 1221b with respect to the axial movement of the lid member 12. Functions as a retainer. The main body 11 and the lid member 12 are configured as disposable members. The main body portion 11 and the lid member 12 are provided to the practitioner in a pre-assembled state. The practitioner may assemble the main body portion 11 and the lid member 12 by himself / herself.

The practitioner inserts the cleaning liquid tube connecting member 13 in which the elastic ring 14 is previously attached to the groove 1441 into the connecting member mounting portion 113 of the main body portion 11 from the tip portion 134 side having the end surface 133. The inner diameter of the small diameter portion 1133 of the connecting member mounting portion 113 of the main body portion 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 elastic ring 14 is formed from the end surface 133 of the cleaning liquid tube connecting member 13. The portion leading to the mounted groove 1441 is fitted into the small diameter portion 1133.

When the cleaning liquid tube connecting member 13 is inserted into the connecting member mounting portion 113, the engaging protrusions 1342a and 1342b are inserted from the fan-shaped portions 1132a2 and 1132a3 of the opening 1131a of the connecting member mounting portion 113. When the tip 134 of the cleaning liquid tube connecting member 13 is inserted to a predetermined position, the circumferential grooves 1131b2 and 1131b3 are continuously provided at the positions corresponding to the engaging protrusions 1342a and 1342b of the connecting member mounting portion 113. Therefore, by rotating the cleaning liquid tube connecting member 13 clockwise with respect to the main body portion 11 when viewed from the cleaning liquid tube side, the engaging protrusions 1342a and 1342b and the substantially wedge shapes of the grooves 1131b2 and 1131b3 mesh with each other. Since the engaging protrusions 1342a and 1342b and the grooves 1131b2 and 1131b3 are more reliably engaged with each other, the cleaning liquid tube connecting member 13 functions as an axial retaining member with respect to the main body portion 11. Further, since the cleaning liquid tube connecting member 13 is provided with the blade portions 1344a and 1344b protruding to the outer diameter side, the cleaning liquid tube connecting member 13 can be easily rotated by hooking a finger on the blade portions 1344a and 1344b. Can be done. Further, 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 surface 1113e of the small diameter portion 1133 of the connecting member mounting portion 113, thereby moving to the connector mounting portion 111 side. Axial movement is restricted.

The male connector 100 is attached to the cleaning unit 10 configured as described above. The male connector 100 is inserted into the insertion hole 121a of the lid member 12 from the tip side. Since the portion of the lid member 12 including at least the insertion hole 121a is formed of an elastic member, the insertion hole 121a is expanded in diameter by elastic deformation according to the shape of the male connector 100 to be inserted. The male connector 100 is further inserted into the connector mounting portion 111 in the axial direction, and the protrusion 1113c is fitted into the flow path 101a of the male connector 100. The male connector 100 is pushed into the connector mounting portion 111 until the end portion of the coupler 103 abuts on the end surface 1113a on the small diameter portion 1112d side of the partition wall 1113 of the connector mounting portion 111.

The cleaning liquid is pumped 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 internal 131 in the cleaning liquid tube connecting member 13, and flows from the diameter-expanded portion 131d into the cleaning liquid inflow hole of the main body portion 11. The cleaning liquid that has flowed in from the cleaning liquid inflow hole is ejected from the cleaning liquid ejection holes 1113d1 to 1113d4 through the flow path in the partition wall 1113. The cleaning liquid ejected from the cleaning liquid ejection holes 1113d1 to 1113d4 flows into the internal space 100b of the male connector 100. The cleaning liquid flowing through the internal space 100b cleans the side surface of the connector main 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 from the second cleaning liquid discharge hole 112c, and is introduced into the cleaning liquid discharge path 112a. Is discharged from.

Further, in the connector coupling portion 100a, the cleaning liquid may leak to the upper side of FIG. 6 from the gap between the main body coupling portion 101c and the coupler coupling portion 103b, but the leaked cleaning liquid is the inner wall portion 1222 of the lid member 12. It falls from between the inner peripheral surface of the inner peripheral surface of the main body 11 and the inner peripheral surface of the small diameter portion 1112d of the main body 11 and the outer peripheral surface of the coupler 103, is introduced into the cleaning liquid discharge path 112a from the first cleaning liquid discharge hole 112b, and is discharged from the drainage cylinder portion 112. Will be done.

(Modification example)
In the first embodiment described above, the insertion hole 121a is provided in the end surface 121 of the lid member 12. The configuration of the portion through which the male connector 100 is inserted is not limited to this. As shown in FIG. 7A, the male connector 100 may be inserted through the slit 121b provided in the end surface 121 of the lid member 12. By elastically deforming the movable piece 121c defined by the slit 121b, an opening for inserting the male connector 100 is easily formed, and the resistance when the male connector 100 is inserted is small. Then, the movable piece 121c elastically returns according to the outer shape of the male connector 100 attached to the predetermined position, so that the opening becomes smaller. Here, the shape and number of the slits 121b can be appropriately selected. For example, as shown in FIG. 7A, slits 121b extending in the radial direction through the central portion of the end surface 121 of the lid member 12 may be arranged at intervals of 45 ° in the circumferential direction. Further, as shown in FIG. 7B, a slit 121d extending in the outer diameter direction from the insertion hole 121a provided in the central portion of the end surface 121 of the lid member 12 may be formed. Compared with 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 the resistance at the time of insertion is small.
It should be noted that this modification can be applied not only to the first embodiment but also to the second embodiment described later.

The configuration of the connector mounting portion 111 and the drainage cylinder portion 112 of the main body portion 21 according to the present embodiment is the same as that of the first embodiment. The configuration of the connecting member mounting portion 213 and the cleaning liquid tube connecting member 23 of the main body portion 21 according to this embodiment is different from that of the first embodiment. Also in this embodiment, the main body portion 21 may be formed of a hard member and may have a disposable configuration on the premise that it is replaced by one or a plurality of washings.

In the cleaning unit according to the present embodiment, the cleaning liquid supplied from the cleaning liquid tube is ejected from the cleaning liquid ejection holes 1113d1 to 1113d4 of the main body portion 21 via the cleaning liquid tube connecting member 23 into the flow path through which the cleaning liquid flows. A check valve 25 is provided to prevent the backflow of drainage after cleaning. In this embodiment, a tube-shaped check valve 25 made of a flexible member is arranged in the flow path from the cleaning liquid tube connecting member 23 to the cleaning liquid inflow hole opened in the end surface 1113e of the small diameter portion 2133 of the connecting member mounting portion 213. ing. The cleaning liquid tube connecting member 23 corresponds to the transport member connecting portion of the present invention.

As shown in FIGS. 10A to 10C, the cleaning liquid tube connecting member 23 has a substantially bottomed cylindrical shape. The hollow inner 231 of the cleaning liquid tube connecting member 23 has a large diameter portion 231a into which the cleaning liquid tube is inserted, a reduced diameter portion 231b that is continuous with the large diameter portion 231a and is reduced in diameter toward the main body portion 21, and a reduced diameter portion. Includes a small diameter portion 231c continuous with 231b. The tip portion 233 side of the small diameter portion 231c connected to the main body portion 21 is closed, and cleaning liquid outflow holes 231d1 and 231d2 penetrating the side wall of the small diameter portion 231c are provided. The cleaning liquid outflow holes 231d1 and 231d2 are provided at positions symmetrical with respect to the axis of the cleaning liquid tube connecting member 23, respectively.

The outer peripheral surface of the cleaning liquid tube connecting member 23 is provided with a large diameter portion 236 via a step portion 235 from the tip portion 234 through which the cleaning liquid outflow holes 231d1 and 231d2 open toward the cleaning liquid tube side. In the large diameter portion 236, a groove 2361 which is concave on the inner diameter side is formed over the entire circumference 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 the small diameter portion 2133 of the connection member mounting portion 213, which will be described later, and the elastic ring 14 mounted on the groove 2361 is set to press contact with the inner peripheral surface of the small diameter portion 2133. Has been done. Engagement protrusions 2362a and 2362b that engage with the main body 21 are formed on the cleaning liquid tube side of the groove 2361. The engaging protrusion 2362a has a rib portion 2362a1 extending over a part in the circumferential direction and protruding toward the outer diameter portion, and a locking portion 2362a2 having a counterclockwise end extending toward the cleaning liquid tube side when viewed from the cleaning liquid tube side. (The engaging projection 2362b also has a similar configuration). The engaging protrusions 2362a and 2362b are arranged rotationally symmetrically with respect to the axis of the cleaning liquid tube connecting member 23. On the outer peripheral surface of the cleaning liquid tube connecting member 23, ribs 2363 extending along the axial direction and protruding in the outer diameter direction are provided at equal intervals in the circumferential direction on the cleaning liquid tube side of the engaging protrusions 2362a and 2362b. The rib 2363 is provided to securely and easily grip the cleaning liquid tube connecting member 23 when the cleaning liquid tube is inserted into the hollow inner portion 231.

The check valve 25 is a cylindrical member made of a flexible member as described above. The inner diameter of the check valve 25 is set to be slightly smaller than the outer diameter of the tip portion 234 of the cleaning liquid tube connecting member 23 in which the cleaning liquid outflow holes 231d1 and 231d2 are opened, and the check valve 25 is mounted on the outer periphery of the tip portion 234. The check valve 25 is in pressure contact with the outer peripheral surface of the tip portion 234. When the cleaning liquid pumped from the cleaning liquid tube flows out from the cleaning liquid outflow holes 231d1 and 231d2, the check valve 25 is deformed to form a gap between the outer peripheral surface of the tip portion 234 of the cleaning liquid tube connecting member 23 and the check valve 25. It passes through and flows out to the main body 21 side. 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 outflow holes 231d1 and 231d2, so that it is upstream from the cleaning liquid outflow holes 231d1 and 231d2. Each part can be contaminated. Further, since the check valve 25 is a cylindrical flexible member that covers the cleaning liquid outflow holes 231d1 and 231d2, the size of the cleaning liquid outflow holes 231d1 and 231d2 and the material and size of the check valve 25 can be set. , The forward flow of the cleaning solution can be easily adjusted.

The configuration of the connection member mounting portion 213 of the main body portion 21 according to this embodiment will be described. Similar to the main body portion 11 according to the first embodiment, the connecting member mounting portion 213 is provided on the side opposite to the connector mounting portion 111 in the axial direction. The connecting 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 continuous with the large diameter portion 2131 via the step portion 2132. Holes 2131c2 and 2131c3 extending in the circumferential direction are provided on the side wall of the large diameter portion 2131 on the stepped portion 2132 side so as to penetrate the side wall from the inner peripheral side to the outer peripheral side. The holes 2131c2 and 2131c3 have a shape that is rotationally symmetric with respect to the axis. Flange portions 2131b2 and 2131b3 protruding toward the inner diameter side are formed on the inner peripheral surface of the large diameter portion 2131 from the edge portion of the holes 2131c2 and 2131c3 on the opening 2131a side to the end surface of the opening 2131a. The circumferential lengths of the flange portions 2131b2 and 2131b3 are substantially the same as the circumferential lengths of the holes 2131c2 and 2131c3. As shown in FIG. 9E, the flange portions 2131b2 and 2131b3 are arranged so as to be rotationally symmetric with respect to the axis.

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 mounting portion 213 of the main body portion 21, the tip portion 234 is inserted from the opening 2131a into the small diameter portion 2133. The elastic ring 14 mounted on the groove 2361 is deformed by being pressed against the inner peripheral surface of the small diameter portion 2133 to keep the small diameter portion 2133 and the tip portion 234 and the cleaning liquid tube side liquid-tight. When the tip portion 234 is inserted through the opening 2131a, the engaging protrusions 2362a and 2362b are arranged with the flange portion 2131b2 and the flange portion in the circumferential direction so that the engaging protrusions 2362a and 2362b do not interfere with the flange portions 2131b2 and 2131b3. Pass through the area between 2131b3. When the tip portion 234 is inserted to a predetermined position of the connecting member mounting portion 213, the engaging protrusions 2362a and 2362b reach a position on the smaller diameter portion 2133 side than the flange portions 2131b2 and 2131b3 in the axial direction. In this way, with the engaging protrusions 2362a and 2362b reaching the positions beyond the flange portions 2131b2 and 2131b3, the cleaning liquid tube connecting member 23 is clockwise when viewed from the cleaning liquid tube side, and the locking portions 2362a2 and 2362b2. Is rotated until it comes into contact with the ends of the flange portions 2131b2 and 2131b3, respectively. When the locking portions 2362a2 and 2362b2 abut on the ends of the flange portions 2131b2 and 2131b3, the clockwise rotation is restricted when viewed from the cleaning liquid tube side, and the engaging projections 2362a and 2362b are restricted when viewed from the cleaning liquid tube side. Since the rib portions 2362a1 and 2362b1 and the flange portions 2131b2 and 2131b3 are in an overlapping positional relationship, the movement of the cleaning liquid tube connecting member 23 to the cleaning liquid tube side is restricted and functions as a retaining mechanism.

Since the attachment of the male connector 100 to the cleaning portion 20 is the same as that in the first embodiment, the description thereof will be omitted.
As shown in FIG. 7A, the lid member 12 of the cleaning unit 20 according to the second embodiment may also be provided with a slit 121b instead of the insertion hole 121a, as shown in FIG. 7B. A slit 121d may be provided in addition to the insertion hole 121a.
