[0053] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0054] The mounting component of this embodiment is mounted on a blood purification device having a peristaltic pump, and holds a pump tube that can be squeezed in a specified direction by the peristaltic pump to deliver liquid, such as Figures 1 to 13 As shown, the mounting component includes: a main body 2 that can be mounted at a predetermined position Ba of the blood purification device B, and a holding part 3 that is mounted on the main body 2 and holds the pump tube C.

[0055] like Figures 7 to 16 As shown in the figure, the mounting member 1 is composed of a resin molded part formed integrally of a main body 2 and a holding portion 3, and is formed by bending a bent portion K formed along a boundary line between the main body 2 and the holding portion 3, as shown in FIG. Figure 7 As shown, the holding portion 3 is attached to the front side of the main body 2. In addition, the bending portion K is formed with a pinhole, etc., so that the holding portion 3 can be easily bent relative to the main body 2.

[0056] like Figures 7 to 13As shown in FIG. 1 , the main body 2 of the present embodiment is composed of a rectangular resin molded part, and has an inclined surface 2a (edge ​​portion) and a central portion 2b, the inclined surface 2a is formed at both sides thereof, and is inclined at a predetermined angle α relative to the bottom surface of the main body 2 (the mounting surface relative to the predetermined position Ba), and the central portion 2b is located at the central position of the main body 2 and between the left and right inclined surfaces 2a. That is, the central portion 2b is formed at the center of the main body 2, and the inclined surfaces 2a with an inclination angle α are formed from the central portion 2b toward the left and right directions, respectively, and a plurality of (four in the present embodiment) holding portions 3 are mounted on each of the inclined surfaces 2a.

[0057] The holding portion 3 is formed by a resin molded portion that is protruded in a block shape relative to the main body portion 2 (bulged toward the front side). Fig.11 , 12 As shown in FIG. 1 , the pump tube C has a retaining groove 3a, which can be respectively fitted with connectors D formed at both ends of the pump tube C and fixed at a predetermined height. That is, by fitting and fixing the connector D into the retaining groove 3a, as shown in FIG. Figures 11 to 13 As shown in FIG. 1 , the pump tube C is held by the holding portion 3. In addition, the holding portion 3 is as shown in FIG. Fig. 9 As shown, a snap-fit ​​hole 3b (snapped portion) is formed at a predetermined position, and the snap-fit ​​member A included in the blood purification device B can be snapped.

[0058] The pump tube C is formed of a soft resin or rubber material having a relatively large diameter flow path, and connectors D are formed at one end and the other end thereof. When the pump tube C is installed in the stator S of the peristaltic pump P, if the rotor R is driven to rotate, the pump tube C is manipulated in the longitudinal direction by the roller Ra, thereby being able to transport liquids such as infusion and drainage.

[0059] However, due to the holding portion 3 of this embodiment, as Fig. 9 , 10 13, the pump tube C is installed on the inclined surface 2a, so the pump tube C is extended and arranged at a predetermined angle α relative to the bottom surface of the body 2 (relative to the installation surface at the predetermined position Ba) (inclined along the inclined surface 2a). That is, the holding portion 3 of this embodiment is arranged so that the connector D of the pump tube C is held in an inclined state, and the pump tube C is directed toward the direction of installation to the peristaltic pump P (towards Fig.13 The pump tube C is maintained while being inclined in the direction of the lower side.

[0060] In addition, the main body 2 of the present embodiment is configured in such a manner that the holding parts 3 are respectively mounted on the edge parts (inclined surfaces 2a) on both sides thereof, and a flexible tube r for circulating liquid is provided in the central part 2b between the holding part 3 formed on one edge part (inclined surface 2a) and the holding part 3 formed on the other edge part (inclined surface 2a). The flexible tube r provided in the central part 2b is a flexible tube connected to the connector D of the pump tube C, or a flexible tube extended from another device.

[0061] In addition, the central portion 2b of the main body 2 of this embodiment is as shown in FIG. Fig.15 , 16 As shown in FIG. 1 , a recess T is formed, the back side (the side of the mounting surface relative to the blood purification device B) of which is open and accommodates the flexible tube r, and the front side (the side opposite to the mounting surface) of which covers the flexible tube r. That is, the central portion 2b of the main body 2 of the present embodiment is formed with a recess T (concave shape) opened on the back side, and is constructed in the following manner: the flexible tube r is covered when viewed from the front side, and the flexible tube r (the tube connected to the connector D of the pump tube C, etc.) is accommodated along the recess T opened on the back side. In addition, it is preferred that at least the central portion 2b of the main body 2 is transparent so that the flexible tube r covered by the central portion 2b can be identified.

[0062] The blood purification device B applicable to this embodiment is as follows Figures 1 to 3 As shown, it is composed of a monitor M that can display information related to blood purification treatment and a monitoring device for hemodialysis treatment having a blood pump N, etc., and is configured in a manner that the patient's blood is circulated extracorporeally in the blood circuit by driving the blood pump N while blood purification treatment is performed in the blood purifier (dialyzer). The blood purification device B of this embodiment includes a plurality of (seven in this embodiment) peristaltic pumps P on the front side, which can deliver supplementary fluid and discharge fluid during blood purification treatment.

[0063] The peristaltic pump P can manipulate the pump tube C in a certain direction to transport liquid, such as Figures 3 to 6 As shown in FIG. 1 , the peristaltic pump P includes a stator S having a mounting recess Sa, a rotor R disposed in the mounting recess Sa and rotatable about a rotation axis L, and a roller Ra mounted on the rotor R. When a pump tube C is mounted in the mounting recess Sa of the stator S and the rotor R is driven to rotate, the pump tube C is conveyed between the wall surface of the mounting recess Sa and the roller Ra to deliver liquid.

[0064] In addition, the rotor R has a pair of upper and lower guide pins a1 and a lower guide pin a2, and a pair of upper and lower guide pins b1 and b2, which are formed to protrude from the stator S, and the pump tube C is installed between the upper guide pin a1 and the lower guide pin a2, and between the upper guide pin b1 and the lower guide pin b2. In addition, the upper guide pins a1 and b1 are located on the opening side of the mounting recess Sa, and the lower guide pins a2 and b2 are located on the bottom surface side of the mounting recess Sa, so that the pump tube C installed in the mounting recess Sa is suppressed from deviating from a predetermined position (a position that can be straightened by the roller Ra).

[0065] The blood purification device B of this embodiment can be provided with a mounting member 1 at a predetermined position Ba on the front side where the peristaltic pump P is provided. Figure 4 As shown, a positioning pin g is formed and inserted into a positioning hole h formed on the main body 2 of the mounting member 1 , thereby positioning the mounting member 1 at a predetermined position Ba of the blood purification device B.

[0066] In addition, at a predetermined position Ba of the blood purification device B in this embodiment, Figure 2 As shown, a plurality of snap-fit ​​parts A are installed, and the holding part 3 has a snap-fit ​​hole 3b (snapped part) that can be snapped on the snap-fit ​​part A as described above. The snap-fit ​​part A has a snap-fit ​​claw formed on one side of its protruding end and a pressing part formed on the other side. By snapping the snap-fit ​​claw on the opening edge of the snap-fit ​​hole 3b, the mounting part 1 is snapped on the snap-fit ​​part A, thereby being installed at the specified position Ba.

[0067] However, when the mounting member 1 is positioned by the positioning pin g and the snap hole 3b (the snapped portion) is snapped by the snap claw of the snap member A, as shown in FIG. Figure 5 As shown in (a), the base end Ca and the front end Cb of the pump tube C held by the holding portion 3 are located above the upper guide pins a1 and b1 of each peristaltic pump P. At this time, the rotor R of each peristaltic pump P is at a predetermined position (refer to Figures 2 to 4 ) is in a stopped state. When the locking state is moved in a direction to retract the locking member A relative to the predetermined position Ba (in a direction to make the mounting member 1 approach the predetermined position Ba), as shown in FIG. Figure 5 As shown in (b), the base end Ca of the pump tube C is located between the upper guide pin b1 and the lower guide pin b2, and the front end Cb of the pump tube C is located above the upper guide pin a1.

[0068] When the rotor R is driven to rotate from this state, as shown in FIG. Figure 5As shown in (c), the base end Ca of the pump tube C is located between the upper guide pin b1 and the lower guide pin b2, while the front end Cb of the pump tube C interferes with the upper guide pin b1 and is wound around the upper guide pin b1 and located between the upper guide pin a1 and the lower guide pin a2, so that the pump tube C is set at an appropriate position relative to the extrusion pump P. In addition, the installation operation in which the pump tube C is wound between the upper guide pin a1 and the lower guide pin a2 and is in a set state is also called loading.

[0069] On the other hand, Figure 6 As shown in (a), when the pump tube C is set on the peristaltic pump P and the snap hole 3b (the snapped part) is snapped on the snap component A, when the snap component A is moved in the protruding direction (the direction to lift the mounting component 1 from the specified position Ba), the pressing part of the snap component A presses the opening edge of the snap hole 3b, and the pump tube C is lifted from the mounting recess Sa. At this time, the rotor R of each peristaltic pump P is in the same specified position as when the pump tube is loaded (refer to Figures 2 to 4 ) is in the stopped state, such as Figure 6 As shown in (b), the front end portion Cb of the pump tube C is located between the upper guide pin b1 and the lower guide pin b2, and the base end portion Ca of the pump tube C is located above the upper guide pin b1.

[0070] When the rotating rotor R is driven from this state, as Figure 6 As shown in (c), the base end Ca of the pump tube C is located above the upper guide pin a1, and the front end Cb of the pump tube C interferes with the upper guide pin b1 and is pushed out, thereby being located above the upper guide pin b1, thereby releasing the set state of the pump tube C relative to the peristaltic pump P and allowing the pump tube C to be removed. In addition, the removal operation of releasing the set state by pushing the pump tube C from between the upper guide pin a1 and the lower guide pin a2 is also called unloading.

[0071] Here, if Figures 14 to 16 As shown, the main body 2 of this embodiment has openings (H1 to H4) through which the flexible tubes (r1, r2) can be inserted at its central portion 2b, and is configured so that the flexible tube r1 can be inserted through the openings (H1, H2) and the flexible tube r2 can be inserted through the openings (H3, H4) and fixed. Specifically, the openings (H1 to H4) are formed in pairs (the opening H1 and the opening H2 are a pair, and the opening H3 and the opening H4 are a pair) separated from each other, and the flexible tubes r1 and r2 can be respectively inserted through and fixed to the pair of openings (the openings H1, H2 and the openings H3, H4).

[0072] That is, the flexible tube r1 is inserted through the opening H1 from the front side of the main body 2 to the recessed portion T on the back side of the central portion 2b, and then is inserted through the recessed portion T to the opening H2 to reach the front side of the main body 2. Thus, the flexible tube r1 is fixed by being inserted through the pair of openings (H1, H2). Similarly, the flexible tube r2 is inserted through the opening H3 from the front side of the main body 2 to the recessed portion T on the back side of the central portion 2b, and then is inserted through the recessed portion T to the opening H4 to reach the front side of the main body 2. Thus, the flexible tube r2 is fixed by being inserted through the pair of openings (H3, H4).

[0073] In addition, in this embodiment, if Fig.17 As shown in (a) of FIG. 1 , the cover H has a plurality of openings for blocking, and the flexible tube r can be inserted by removing the cover H. For example, a portion of the cover H is connected to the central portion 2b of the main body 2, and if pressed with a finger, the connection is cut or bent, as shown in FIG. Fig.17 As shown in (b) of FIG. 1 , the opening H1 (or H2 to H3) is formed. Alternatively, the lid portion H may not be formed but the openings H1 to H4 may be formed, and the flexible tube r may be inserted through any of the openings H1 to H4.

[0074] Furthermore, the openings H1 to H4 may also be formed at their inner diameters t1 (see Fig.17 (b)) is smaller than the outer diameter t2 of the flexible tube r. In this case, the flexible tube r is pressed in when being inserted into the openings H1 to H4. In addition, the inner diameter t1 of the openings H1 to H4 is preferably set according to the flexible tube r (material, wall thickness, etc.) or the fixed position of the flexible tube r. In this case, since the degree of pressing varies according to the difference between the inner diameter t1 and the outer diameter t2, the clamping force of the flexible tube r can be arbitrarily adjusted.

[0075] In addition, the central portion 2b of the main body 2 of this embodiment is formed with a recess T, the back side of which is open to accommodate the flexible tube r, and the front side (the side opposite to the mounting surface) covers the flexible tube r, but it may also be Fig.18 , 19 As shown in FIG. 2 , a recess T is formed, the front side of which is open to accommodate the flexible tube r, and the back side of which covers the flexible tube r. In this case, the recess T formed in the central portion 2b is also formed with openings (H1 to H4) as a fixing portion, and the flexible tube r accommodated in the recess T is inserted through the openings (H1 to H4) and fixed.

[0076] In addition, if Fig. 20 and 21As shown, the center portion 2b of the main body 2 may be a flat surface instead of forming the recess T in the center portion 2b, and the flexible tube r may be placed on the flat surface. Even in this case, an opening (H1 to H4) as a fixing portion is formed in the center portion 2b of the flat surface, and the flexible tube r is inserted through the opening (H1 to H4) and fixed.

[0077] In addition, in the present embodiment, a mark that can identify the opening is added to each cover H. For example, the mark can be identified by various symbols, characters, shapes or colors in addition to the numbers written on the cover H as in the present embodiment. In addition, a structure can be set to determine the opening through which the flexible tube r passes. In this case, the opening through which the flexible tube r should pass can be set for each treatment.

[0078] If the mounting component 1 is buckled at a predetermined position Ba of the blood purification device B, and the pump tubes C are respectively mounted on a plurality of peristaltic pumps P, then Fig.23 As shown, a treatment device for blood purification treatment is constituted. The treatment device includes: a blood circuit U having a dialyzer Q; a first dialysate introduction pipeline L1a and a second dialysate introduction pipeline L1b, which introduce the dialysate into the dialyzer Q; a first infusion pipeline L2a, a second infusion pipeline L2b, a front infusion pipeline L2c and a rear infusion pipeline L2d, which supply infusion to the blood circuit U; a first drainage discharge pipeline L3a and a second drainage discharge pipeline L3b, which discharge the drainage of the dialyzer Q.

[0079] The blood circuit U is configured to include an arterial blood circuit Ua and a venous blood circuit Ub. The front ends of the arterial blood circuit Ua and the venous blood circuit Ub are punctured into the patient, and the blood pump N is driven, thereby allowing the patient's blood to circulate extracorporeally. In addition, the dialyzer Q has a blood inlet port Qa, a blood outlet port Qb, a dialysate inlet port Qc, and a dialysate outlet port Qd formed protrudingly on its outer shell. The arterial blood circuit Ua is connected to the blood inlet port Qa, the venous blood circuit Ub is connected to the blood outlet port Qb, the second dialysate inlet line L1b is connected to the dialysate inlet port Qc, and the first dialysate outlet line L3a is connected to the dialysate outlet port Qd.

[0080] The first dialysate introduction line L1a is connected to a dialysate receiving bag W1 that receives dialysate, and is connected to the second dialysate introduction line L1b via a subdividing cavity T. When the peristaltic pumps P provided on the first dialysate introduction line L1a and the second dialysate introduction line L1b are driven, the dialysate in the dialysate receiving bag W1 is subdivided in the subdividing cavity T and then introduced into the dialyzer Q.

[0081] The first fluid infusion line L2a is connected to a fluid infusion storage bag W2 that stores the fluid infusion, and is connected to the second fluid infusion line L2b via a subdividing chamber T. The second fluid infusion line L2b is connected to the blood circuit U via a front fluid infusion line L2c connected to the arterial blood circuit Ua and a rear fluid infusion line L2d connected to the venous blood circuit Ub. In addition, a check valve V1 is connected to the rear fluid infusion line L2d. Furthermore, if the peristaltic pump P provided on the first fluid infusion line L2a and the second fluid infusion line L2b is driven, the fluid in the fluid infusion storage bag W2 is subdivided in the subdividing chamber T, and then introduced into the arterial blood circuit Ua or the venous blood circuit Ub according to the driving state of the peristaltic pump P provided on the front fluid infusion line L2c.

[0082] The first drainage discharge line L3a is connected to the dialyzer Q, and is connected to the second drainage discharge line L3b via the subdividing chamber T. The second drainage discharge line L3b can discharge drainage to the outside of the device. Furthermore, if the peristaltic pump P provided on the first drainage discharge line L3a and the second drainage discharge line L3b is driven, the drainage in the dialyzer Q can be discharged to the outside of the device after being subdivided in the subdividing chamber T.

[0083] As such, the pump tube C of the mounting component 1 is respectively connected with a flow path (the first fluid infusion introduction line L2a, the second fluid infusion introduction line L2b, and the front fluid infusion line L2c) for introducing the infusion fluid into the blood circuit U, a flow path (the first dialysate introduction line L1a and the second dialysate introduction line L1b) for introducing the dialyzer Q (blood purifier) ​​connected to the blood circuit U, and a flow path (the first discharge line L3a and the second discharge line L3b) for discharging the discharge fluid of the dialyzer Q (blood purifier). In addition, the pump tube C of the mounting component 1 may also be connected to the rear fluid infusion line L2d.

[0084] In addition, in the present embodiment, the pump tube C of the component 1 is not mounted on the blood pump N, but the pump tube C of the mounting component 1 may be mounted on the blood pump N. In this case, the blood circuit U is connected to the pump tube C of the mounting component 1. That is, as the types that can be loaded in the pump tube C of the mounting component 1 of the present invention, there are listed a blood circuit U for extracorporeal circulation of blood; a flow path for introducing infusion fluid into the blood circuit U (the first infusion fluid line L2a, the second infusion fluid line L2b, the front infusion fluid line L2c (or the rear infusion fluid line L2d)); a flow path for introducing dialysate into the dialyzer Q (blood purifier) ​​connected to the blood circuit U (the first dialysate introduction line L1a and the second dialysate introduction line L1b), or a blood purification circuit formed by a flow path for discharging the effluent of the dialyzer Q (blood purifier) ​​(the first effluent discharge line L3a and the second effluent discharge line L3b).

[0085] According to the above embodiment, the main body 2 has the openings H1 to H4 through which the flexible tubes r1 and r2 for liquid circulation can be inserted, and the flexible tubes r1 and r2 can be inserted and fixed to the openings H1 to H4, so that the limited space can be effectively and flexibly utilized and the flexible tubes r1 and r2 can be reliably fixed. In addition, the openings H1 to H4 can be formed so that the inner diameter t1 thereof is smaller than the outer diameter t2 of the flexible tubes r1 and r2. In this case, the flexible tubes t1 and t2 can be pressed into the openings H1 to H4 and firmly fixed, so that the limited space can be effectively and flexibly utilized and the flexible tubes r1 and r2 can be more reliably fixed. Furthermore, the inner diameter t1 of the openings H1 to H4 can be set according to the flexible tubes r1 and r2 or the fixing positions of the flexible tubes r1 and r2. In this case, the clamping force of the flexible tubes r1 and r2 can be arbitrarily adjusted, and the flexible tubes r1 and r2 can be fixed with the clamping force corresponding to the fixing positions of the flexible tubes r1 and r2.

[0086] In addition, the openings H1 to H4 of the present embodiment are separated from each other to form a pair, and the flexible tubes r1 and r2 can be respectively inserted through and fixed to the pair of openings H1 to H4. Therefore, the flexible tubes r1 and r2 can be clamped at two locations and fixed more reliably.

[0087] In addition, since the cover H for blocking the openings (H1 to H4) is provided, the flexible tubes (r1, r2) can be inserted by removing the cover H, and thus the cover H for fixing the openings (H1 to H4) of the flexible tubes (r1, r2) can be arbitrarily removed and selectively opened. Furthermore, since marks for identifying the openings H1 to H4 are added, the operator can recognize the openings H1 to H4 through which the flexible tubes r1 and r2 are to be inserted, and can prevent the flexible tubes r1 and r2 from being inserted into the wrong openings H1 to H4. Furthermore, when the openings H1 to H4 through which the flexible tubes r1 and r2 are to be inserted are set for each treatment, the setting can be easily changed, and the mounting member 1 can be easily used for different treatments.

[0088] In addition, if the openings H1 to H4 through which the flexible tubes r1 and r2 are inserted can be determined, the situation in which the flexible tubes r1 and r2 are inserted through the openings H1 to H2 in the wrong positions can be identified and reported, and in the case where the openings H1 to H4 through which the flexible tubes r1 and r2 should be inserted are set during each treatment, the treatment performed by the blood purification device B can be identified by determining the openings H1 to H4 used for fixing.

[0089] Moreover, retaining portions 3 are respectively installed on the edge portions (inclined surfaces 2a) on both sides of the main body portion 2, and a flexible tube r for allowing liquid to circulate is provided in the central portion 2b between the retaining portion 3 formed on the edge portion (inclined surface 2a) of one and the retaining portion 3 formed on the edge portion (inclined surface 2a) of the other, thereby avoiding complication in handling of the flexible tube r and effectively utilizing limited space.

[0090] In addition, the central portion 2b of the present embodiment is formed with a recessed portion T, and the back side thereof is open to accommodate the flexible tube r, and the front side thereof covers the flexible tube r, so that the flexible tube r can be accommodated in the recessed portion T, and the front side is covered by the central portion 2b, so that other equipment and the like can be prevented from interfering with the flexible tube r. However, it is preferable that the central portion of the main body 2 is transparent, in which case, other equipment and the like can be prevented from interfering with the flexible tube r covered by the central portion 2, and the presence or absence of liquid in the flexible tube r can be easily visually checked through the transparent central portion 2.

[0091] In addition, if Fig.18 , 19 As shown in FIG. 1 , a recess T is formed in the central portion 2b, and the front side thereof is open to accommodate the flexible tube r, and the back side thereof covers the flexible tube r. The flexible tube r can be accommodated in the recess T, and the flexible tube r provided in the central portion 2b can be directly visually viewed. In particular, the central portion 2b of the present embodiment is formed with a fixing portion (opening (H1 to H4)) for fixing the flexible tube r, so that the flexible tube r can be reliably accommodated in the region of the central portion 2b, and the flexible tube r provided in the central portion 2b can be prevented from accidentally reaching other locations.

[0092] Moreover, the fixing portion (fixing portion formed in the central portion 2b) of the present embodiment is composed of openings (H1~H4) through which the flexible tube r can be inserted, and the flexible tube can be inserted and fixed in the openings (H1~H4), so the flexible tube r can be reliably accommodated in the area of ​​the central portion 2b, and no space is required for fixing the flexible tube r, which can avoid enlargement of the main body.

[0093] The present embodiment has been described above, but the present invention is not limited thereto. Fig. 22 As shown, a slit t connecting a pair of openings may be formed in the main body 2. In this case, the flexible tube r can be easily inserted into the pair of openings (H1 to H4), and the corresponding pair of openings (H1 to H4) can be clearly identified, thereby preventing the flexible tube r from being inserted into the wrong opening (H1 to H4).

[0094] In addition, in the present embodiment, an opening (H1 to H4) is formed at the central portion 2b of the main body 2 as a fixing portion of the flexible tube r, but it may be a fixing portion of other types, or it may not be formed. In addition, the retaining portion 3 of the present embodiment is composed of an integral portion bent from the main body 2, and can be swung with the bent portion K as an axis, but the retaining portion 3 may be integrally formed on the upper portion of the main body 2 without swinging (displacing). In addition, the positions of the positioning pin g and the positioning hole h may also be other arbitrary positions, or may be applicable to a blood purification device B without a positioning pin g, or may be a mounting component 1 without a positioning hole h.

[0095] (Industrial Application Possibility)

[0096] As long as the main body has retaining parts installed on the edge parts on both sides thereof, and a mounting component having a flexible tube for circulating liquid is provided in the center part between the retaining parts formed on one edge part and the retaining parts formed on the other edge part, it may be a type with additional functions.
