  Hereinafter, a tube guide holder according to an embodiment will be described with reference to the drawings. FIG. 1 is a perspective view of a tube guide holder (before holding a tube) according to an embodiment.

  As shown in FIG. 1, the tube guide holder 2 includes a first holder 6 and a second holder 8 that guide and hold the tube 4 at a predetermined position. The first holder 6 is a holder on the receiving side fixed at a predetermined position, and has two C-shaped guides (first holder side guides) 6a and 6b. That is, the C-shaped guides 6a and 6b are respectively provided at both ends in the longitudinal direction of the base portion 6c having a rectangular shape in plan view. Here, each of the C-shaped guides 6a and 6b is composed of two inclined portions extending in the side wall direction of the base portion 6c. Further, a groove portion 6d extending in the longitudinal direction of the base portion 6c is formed between the two inclined portions constituting the square-shaped guides 6a and 6b.

  The first holder 6 includes a sensor 7 (see FIG. 3) that senses the inside of the tube 4 from the outside of the tube 4, for example, a pressure sensor that detects the internal pressure of the tube 4 and a bubble sensor that detects air bubbles in the tube 4. Yes.

  The second holder 8 is a push-side holder that translates in the direction of the arrow shown in FIG. 1 on the first holder 6 side, and guides and pushes the tube 4 into the groove 6d of the first holder 6. It has character-shaped guides (second holder side guides) 8a and 8b. That is, the C-shaped guides 8a and 8b are provided at both ends in the longitudinal direction of the base portion 8c having a rectangular shape in plan view. Here, the C-shaped guides 8a and 8b are each constituted by two inclined portions extending in the side wall direction of the base portion 8c.

  The distance between the two C-shaped guides 8 a and 8 b of the second holder 8 is wider than the distance between the two C-shaped guides 6 a and 6 b of the first holder 6. That is, when the tube 4 is guided and held by the first holder 6 and the second holder 8, the two C-shaped guides 8 a and 8 b of the second holder 8 are replaced with the two C-shaped guides 6 a of the first holder 6. , 6b.

  Further, a groove portion 8d extending in the longitudinal direction of the base portion 8c is provided between two inclined portions constituting the square-shaped guides 8a and 8b. A pusher 8e having a predetermined height is provided in the groove 8d. Here, the pusher 8e is formed at a height that protrudes toward the first holder 6 from the bottom of the groove 8d. Further, in the vicinity of both end portions of the side wall of the second holder 8, concave portions 8f are formed in which the tip portions of the C-shaped guides 6a and 6b of the first holder 6 are located.

  FIG. 2 is a perspective view of the tube guide holder (after holding the tube), and FIG. 3 is a view showing a side surface of the tube guide holder (after holding the tube).

  In the tube guide holder 2, the two C-shaped guides 6 a and 6 b of the first holder 6 and the two C-shaped guides 8 a and 8 b of the second holder 8 are opposed to each other, and the second holder 8 is set to the first holder 6. 1, that is, when the second holder 8 is brought close to the first holder 6 in the direction of the arrow shown in FIG. 1, the recesses 8 f formed in the vicinity of both ends of the side wall of the second holder 8 The tips of the C-shaped guides 6a and 6b are located. In this case, the tube 4 positioned between the two C-shaped guides 6 a and 6 b of the first holder 6 and the two C-shaped guides 8 a and 8 b of the second holder 8 is connected to the two of the first holder 6. The C-shaped guides 6a and 6b and the two C-shaped guides 8a and 8b of the second holder 8 are guided and held at predetermined positions.

  That is, when the second holder 8 is moved in parallel to the first holder 6 side which is the radial direction of the tube 4 (see FIG. 4A), the tube 4 is guided by the C-shaped guides 8a and 8b of the second holder 8. Is picked up, and the tube 4 is transferred from the C-shaped guides 8a and 8b to the two C-shaped guides 6a and 6b of the first holder 6 (see FIG. 4B). Then, after guiding the tube 4 to the groove 6d by the C-shaped guides 8a and 8b of the second holder 8 (see FIG. 4C), the tube 4 is pushed into the groove 6d by the pusher 8e (FIG. 4D). reference).

  Therefore, according to the tube guide holder 2 according to this embodiment, even when the position of the tube 4 is deviated, the misalignment of the tube 4 can be corrected and accurately guided to the groove 6d without being bitten. Thus, labor for setting the tube 4 can be saved, and operability can be improved. Further, since the pusher 8e is formed at a height that protrudes toward the first holder 6 from the bottom of the groove 8d, the tube 4 can be reliably pushed into the bottom of the groove 6d of the first holder 6.

  FIG. 5 is a perspective view showing the blood purification apparatus and the extracorporeal circulation cassette. The blood purification apparatus 20 is an apparatus for purifying blood collected from a patient by circulating outside the body. A cassette slot 20a into which the extracorporeal circulation cassette 22 is inserted and mounted is provided on the front surface of the blood purification device 20. A tube guide holder 2 for guiding the tube 4 to a predetermined position is disposed at a predetermined position, which will be described later, in the cassette slot 20a. In the following description, guiding the blood tube access parts 30a and 30b provided in the blood circuit 30 to the predetermined position by the tube guide holder 2 will be described.

  The extracorporeal circulation cassette 22 includes a tube storage portion 24 and a dialyzer holding portion 28 for holding the dialyzer 26 when inserted into the cassette slot 20a of the blood purification device 20. At a substantially central portion of the tube storage portion 24, the blood purification device 20 uses the blood tube access portions 30a, 30b, 30c and dialysate tube access portions 32a, 32b, which will be described later, to sense inside and flow the liquid in the tube. When performing control etc., the opening part 24a in which the tube guide holder 2 is set to an appropriate position is formed.

  The tube storage unit 24 stores the blood circuit 30 configured by a flexible tube and the dialysate circuit 32 configured by a flexible tube in the tube storage unit 24. Here, the blood circuit 30 includes blood tube access units 30a, 30b, and 30c in which a dialyzer 26 is connected in the middle and a bubble sensor or the like is set at an appropriate position when, for example, bubbles are detected by the blood purification device 20.
