  Above the guide hole 51e in the laterally outer surface of the fixed left plate portion 51b and the fixed right plate portion 51c, the longitudinal direction of the holder body 10 and the rotation side rear plate portion 53a of the rotation member 53 described later are provided. An angle scale is provided for the connecting operator to visually confirm the angle formed with the longitudinal direction.

  The rotation member 53 has a length in the vertical direction that is substantially the same as that of the fixed member 51, and a rotation-side rear plate portion 53a that is slightly narrower in the left-right direction than the fixed-side front plate portion 51a, and a rotation-side rear plate. The rotation side left board part 53b extended ahead from the left edge part of the part 53a, and the rotation side right board part 53c extended ahead from the right edge part of the rotation side rear board part 53a are provided.

  A pair of rotation-side shaft holes 53d in which screw grooves for screwing the shaft screws 52 are formed in the lower portions of the rotation-side left plate portion 53b and the rotation-side right plate portion 53c. A lock hole 53f for attaching a lock screw 53e for limiting the rotation angle of the rotation member 53 by screwing is formed in the upper part of the rotation side left plate portion 53b and the rotation side right plate portion 53c. The lock screw 53e protrudes inward in the left-right direction from the guide hole 51e of the fixing member 51 and is attached to the lock hole 53f by screwing.

  Bolt insertion holes 53g for inserting bolts B2 (shown in FIG. 15) and the like attached to the side surface W (shown in FIG. 15) of the dialyzer are formed in the upper and lower portions of the rotation-side rear plate portion 53a. ing. The holder 1 is attached to a dialysis machine or the like by inserting the bolt B2 into the bolt insertion hole 53g and fastening it to the side surface W of the dialysis machine. The bolt insertion hole 53g is a so-called dharma hole in which a large diameter portion through which the head of the bolt B2 is inserted and a small diameter portion having the same size as the outer diameter of the shaft portion of the bolt B2 are continuous. is there.

  When the angle adjusting unit 50 is attached to the holder body 10 and the holder 1 is attached to the side surface W of the dialysis machine, the bolt B2 attached to the side face W of the dialysis machine is first loosened and the bolt B2 is rotated from the head. After passing through the large diameter portion of the bolt insertion hole 53g of the member 53, the shaft portion of the bolt B2 is hooked to the small diameter portion of the bolt insertion hole 53g. Then, the bolt B2 on the side surface W of the dialysis machine is strongly tightened and attached. Next, in a state where the rotating member 53 is accommodated inside the fixing member 51 attached to the holder main body 10 in the left-right direction, the shaft screw 52 is inserted into the fixed-side shaft hole 51d from the outer side in the left-right direction, and the rotating side shaft is inserted. Screwed into the hole 53d. Then, the lock screw 53e is inserted into the guide hole 51e of the fixing member 51 from the outside in the left-right direction, and is fastened to the lock hole 53f of the rotation member 53 by screwing. The fixing member 51 is fixed with respect to 53, and it is set as a locked state. When the lock screw 53e is loosened, the fixing member 51 rotates around the shaft screw 52 with respect to the rotation member 53. At this time, as will be described later, the longitudinal direction of the rotational side rear plate portion 53a coincides with the vertical direction while the rotational side rear plate portion 53a is attached to the side surface W (shown in FIG. 15) of the dialyzer. In this case, since the fixing member 51 is attached to the holder main body 10, it is possible to adjust the angle between the longitudinal direction of the holder main body 10 and the vertical line by rotating the fixing member 51 around the shaft screw 52. It is.

  Next, the case where the filtration filter F is connected to the holder 1 configured as described above will be described. First, as shown in FIG. 7, the filtration filter F is arranged in front of the holder 1 so that the longitudinal direction of the holder body 10 and the longitudinal direction of the housing F1 of the filtration filter F coincide. Here, the inflow pipe portion F11 and the outflow pipe portion F12 of the filtration filter F protrude toward the holder body 10, and the front casing 21 of the inflow side connection portion 20 and the front casing 31 of the outflow side connection portion 30 respectively flow into the inflow pipe portion F11. And the filtration filter F is arrange | positioned so that the outflow pipe part F12 may be opposed.

  At this time, as shown in an enlarged view in FIG. 8, the lower indicator 70 is lowered from the lower light color portion 71 to the lower dark color portion 72 by the urging force of the coil spring 451 built in the lower housing portion 45. The inflow pipe portion F11 is exposed from the side housing portion 45 and is not connected to the inflow side connection portion 20 and is in a disconnected state.

  Next, as shown in FIG. 9, the leading ends of the inflow pipe portion F11 and the outflow pipe portion F12 are respectively connected to the elastic cylinder 23 (shown in FIG. 4 and the like) of the inflow side connection section 20 and the elastic cylinder 33 (see FIG. 4). As shown in FIG. At this time, the housing F1 approaches the handle 40, and the connecting worker can put his / her finger on the connecting portion 43 of the handle 40 from the rear with the palm in front of the housing F1.

  At this time, as shown in an enlarged view in FIG. 10, the inner diameter of the front end surface of the elastic tube 23 of the inflow side connecting portion 20 is larger than the outer diameter of the front end portion of the inflow tube portion F11. Even if the direction is slightly deviated from the axial direction of the elastic cylinder 23, the connecting operator can easily insert the tip of the inflow pipe portion F11 into the elastic cylinder 23. And the inflow side step part F11d of the inflow pipe part F11 contacts the annular engagement protrusion 232 provided on the inner peripheral surface of the elastic cylinder 23 of the inflow side connection part 20.

  At this time as well, the lower indicator 70 remains exposed from the lower accommodating portion 45, indicating that the inflow pipe portion F11 is in a disconnected state.

  From this state, when a force is applied so as to grasp the housing F1 and the handle 40 together, a force in a direction approaching the holder body 10 acts on the housing F1, and the inflow pipe portion F11 is connected to the inflow side connection portion 20. The force pushed into the inflow side insertion hole 23a in the inside acts on the protruding direction of the inflow pipe portion F11. Then, due to the pushing force, as shown in FIG. 11, the inflow side step portion F11d of the inflow pipe portion F11 moves the annular engagement protrusion 232 of the elastic tube 23 of the inflow side connection portion 20 to the rear side and radially outward. While pressing, the annular engaging protrusion 232 is moved radially outward, and the elastic cylinder 23 is elastically deformed radially outward. Then, the inflow pipe portion F11 is inserted into the inflow side insertion hole 23a, and the inflow side flat portion F11c of the inflow pipe portion F11 contacts the annular engagement protrusion 232 of the elastic cylinder 23 from the radially inner side to the radially outer side. Press.

  At this time, a portion of the outer peripheral surface of the lower portion of the housing F1 facing rearward is in contact with the front end of the lower indicator 70 in the protruding direction, but the lower indicator 70 remains exposed from the lower housing portion 45, It shows that the inflow pipe portion F11 is in a disconnected state.

  Further, as shown in FIG. 12, when a force is applied so as to grip the housing F1 and the handle 40 together, the inflow pipe portion F11 is inserted into the inflow side insertion hole 23a of the inflow side connection portion 20 in the insertion direction back side. As shown in FIG. 13, the position of the inflow side annular groove F <b> 11 a of the inflow pipe portion F <b> 11 in the axial direction of the elastic cylinder 23 is a position corresponding to the annular engagement protrusion 232 of the elastic cylinder 23. Then, the annular engagement protrusion 232 of the elastic tube 23 that has been pressed radially outward by the inflow side flat portion F11c of the inflow tube portion F11 contracts in a direction to return to the radially inner side of the elastic tube 23 by elastic force. , Engage with the inflow side annular groove F11a of the inflow pipe portion F11. Even in this state, the elastic cylinder 23 has not returned to the non-insertion state (shown in FIG. 8) in which the inflow pipe portion F11 is not inserted, and the elastic cylinder 23 will contract inward in the radial direction in the inflow pipe portion F11. The elastic force is acting.

  At this time, the portion of the outer peripheral surface of the lower portion of the housing F1 facing backward contacts the lower indicator 70 from the front and presses backward, so that the lower dark color portion 72 of the lower indicator 70 is The coil spring 451 is pushed into and accommodated in the lower accommodating portion 45 against the biasing force of the coil spring 451 incorporated in the lower accommodating portion 45. Therefore, only the lower light colored part 71 is exposed from the lower accommodating part 45, and the inflow pipe part F11 is in a connected state connected to the inflow side connecting part 20.

  The above-described series of movements related to the inflow side connection portion 20 is also occurring in the outflow side connection portion 30 shown in FIG. 12 at the same time, so that the inflow pipe portion F11 and the outflow pipe portion F12 are respectively in The filtration filter F is held by the holder 1 by being pushed into the connecting portion 30 and simultaneously connected. In this state, the annular engagement protrusions 232 and 332 engage with the inflow side annular groove F11a and the outflow side annular groove F12a by the elastic force of the elastic cylinders 23 and 33, and the inflow pipe portion F11 and the outflow pipe portion F12 It is difficult to come out from the inflow side connection part 20 and the outflow side connection part 30, respectively.

  In addition, a series of movements related to the lower indicator 70 is simultaneously occurring in the upper indicator 60 as well. Therefore, since the connection operator can use the filter F after confirming that the inflow pipe part F11 and the outflow pipe part F12 are in a connected state easily and reliably, the inflow pipe part F11 or the outflow pipe part F12 is not connected. Liquid leakage due to the use of the filter F in the state can be prevented.

  At this time, in a state where the filter F is held by the holder 1 (shown in FIG. 15), a gap is formed between the housing F1 and the connecting portion 43 of the handle portion 40. Even if there is an error in the dimensions of the portion 40 and the like, the housing F1 and the connecting portion 43 do not come into contact with each other, and the filtration filter F is securely held by the holder 1.

  Further, as shown in FIG. 14, when the holder 1 is viewed from the front (the insertion direction of the inflow tube portion F11 and the outflow tube portion F12 into the inflow side insertion hole 23a and the outflow side insertion hole 33a), Since the position of the portion 40 is substantially at the center of the housing F1 in the left-right direction (a position overlapping the housing F1), the connecting worker can determine whether the inflow pipe portion F11 and the outflow tube portion F12 protrude in the inflow side insertion hole 23a and the outflow side. The inflow pipe portion F11 and the outflow pipe portion F12 can be pushed into the inflow side connection portion 20 and the outflow side connection portion 30 substantially simultaneously (with equal force) along the insertion direction of the insertion hole 33a. Accordingly, the inflow pipe portion F11 and the outflow pipe portion F12 are smoothly inserted into the inflow side insertion hole 23a and the outflow side insertion hole 33a and connected to the inflow side connection portion 20 and the outflow side connection portion 30.

  12, since the connecting portion 43 of the handle portion 40 extends long in the longitudinal direction of the holder body 10 and the housing F1, a palm is applied to the housing F1 and a plurality of fingers are hung on the handle portion 40. be able to. Therefore, when the housing F1 and the handle 40 are gripped together, it is easy to apply a force that pushes the inflow pipe part F11 and the outflow pipe part F12 into the inflow side connection part 20 and the outflow side connection part 30.

  Next, the case where the filtration filter F hold | maintained at the holder 1 as mentioned above is used is demonstrated. First, as shown in FIG. 15, the raw water supply tube T1 is formed in the inflow side L-shaped tube 24 protruding from the rear of the holder 1, the drainage tube T2 is disposed in the outflow side L-shaped tube 34, and the upper tube portion of the filtration filter F. The pure water outflow tubes T3 are respectively connected to F2a, and the lower tube portion F3a of the filter F is liquid-tightly covered with the cap Fc. And the pure water outflow tube T3 connected to the upper tube portion F2a is inserted into the tube insertion hole 10a in the upper part of the holder body 10 and connected to a dialysis machine (not shown).

  When raw water is supplied to the raw water supply tube T1 in this state, the raw water is supplied into the housing F1 through the inside of the inflow side L-shaped tube 24, the inside of the elastic cylinder 23, and the inside of the inflow tube portion F11. Part of the raw water supplied into the housing F1 is filtered through a hollow fiber membrane F4 (shown in FIG. 2), and as pure water, the inside of the hollow fiber membrane F4, the inside of the upper tube portion F2a, and pure water outflow The dialysis apparatus (not shown) is supplied through the inside of the tube T3. On the other hand, the raw water that does not pass through the hollow fiber membrane F4 is discharged from the drainage tube T2 through the inside of the outflow pipe portion F12, the inside of the elastic cylinder 33, and the inside of the outflow side L-shaped pipe 34.

  At this time, since the holder 1 holds the filtration filter F so that the raw water is filtered from the outside to the inside of the hollow fiber membrane F4 (shown in FIG. 2), the raw water is supplied from the inside to the outside of the hollow fiber membrane F4. Compared with the case of filtration, clogging of the filter F is less likely to occur, and the filtration performance of the filter F can be maintained for a long time.

  Even if the raw water inflow pressure rises, as shown in FIG. 13, the elastic cylinder 23 of the inflow side connection portion 20 is housed inside the front casing 21 in the radial direction. Hard to elastically deform outward. Therefore, liquid leakage from between the elastic cylinder 23 and the inflow pipe portion F11 is suppressed. Similarly, even when the outflow pressure of the raw water rises, the elastic cylinder 33 of the outflow side connection portion 30 (shown in FIG. 15 and the like) is housed inside the front casing 31 in the radial direction, so that the elastic cylinder 33 has a diameter. Hard to elastically deform outward. Therefore, liquid leakage from between the elastic cylinder 33 and the outflow pipe portion F12 is suppressed.

  In addition, when raw water is introduced from the inflow pipe portion F11 at the start of use of the filtration filter F, air bubbles adhere to the surface of the hollow fiber membrane F4 (shown in FIG. 2) and air bubbles accumulate in the upper portion of the housing F1. If bubbles accumulate in the housing F1, the contact area between the raw water and the hollow fiber membrane F4 is reduced, so that the filtration area is reduced and the filtration performance is deteriorated, and the pressure fluctuation in the flow path of the raw water is increased. There is the problem of inducing errors in the device (not shown). Here, as indicated by phantom lines in FIG. 15, the rotation member 53 of the angle adjustment unit 50 is rotated around the shaft screw 52 with respect to the fixing member 51 to be in a locked state, and the rotation-side rear plate portion 53a is If the longitudinal direction of the rotation-side rear plate portion 53a is made to coincide with the vertical direction against the side surface W of the dialysis device, the upper part of the housing F1 is inclined forward, so that bubbles in the housing F1 Is accumulated on the rear side of the upper portion of the pipe, that is, the outflow pipe portion F12 side. Therefore, the air bubbles in the housing F1 are smoothly guided into the outflow pipe portion F12, pass through the inside of the elastic cylinder 33 of the outflow side connection portion 30 and the inside of the outflow side L-shaped tube 34, and are discharged from the drain tube T2. Is done. Accordingly, since all the bubbles are eliminated from the housing F1, the filtration area is kept wide, and the performance when the filtration filter F is used can be enhanced. Moreover, the pressure fluctuation in a raw | natural water flow path is suppressed, and the error of the dialysis apparatus (not shown) resulting from a pressure fluctuation can be suppressed.

  As described above, according to the holder 1 according to the first embodiment, the inflow side connection part 20 and the outflow side connection of the holder 1 to which the inflow pipe part F11 and the outflow pipe part F12 of the filtration filter F are pushed and connected are connected. Since the handle 40 is provided between the parts 30 for the connection operator to handle, the connection operator can easily put the filter F in the holder 1 without performing complicated operations such as operation of the lock lever. Can be retained.

  Further, since the gap is formed between the housing F1 and the handle 40 with the filter F being held by the holder 1, there is an error in the dimensions of the housing F1, the handle 40, and the like. Even so, the housing F1 and the handle 40 do not come into contact with each other, and the connection operator can securely hold the filter F in the holder 1.

  Moreover, since the angle adjustment part 50 which adjusts the angle which the longitudinal direction of the housing F1 and a perpendicular line make is provided, the performance at the time of use of the filtration filter F can be improved.

  Moreover, since the upper indicator 60 and the lower indicator 70 which show whether the outflow pipe part F12 and the inflow pipe part F11 are in a connection state are provided, the outflow pipe part F12 or the inflow pipe part F11 is in a disconnected state. Liquid leakage due to the use of F can be prevented.
