Examples of the material constituting the float body 2 include foamed resin materials such as polyethylene, polyurethane, polyvinyl chloride, polypropylene, urethane sponge, synthetic rubber, and various elastomers.

As shown in FIG. 1, the plurality of first hole portions 3 are arranged at a central position of each side length of the square float body 2 at a position slightly closer to the center portion than each outer peripheral surface 2 </ b> A of the float body 2. One is formed. These four first holes 3 are formed in a substantially circular shape in plan view. The 1st hole 3 clamps the outer peripheral part of the blood component storage container (refer FIG. 2) 6 as a liquid storage container mentioned later.
A plurality of second holes 5 are formed in total at the four corners on the two diagonal lines of the float body 2 and at the center of the float body 2. These five second holes 5 are formed in a substantially circular closed loop shape having a diameter larger than that of the first holes 3. The second hole 5 sandwiches a test tube, a microtube, or the like having an outer peripheral surface that gradually increases in diameter from one end side toward the other end side.

  A total of four slit portions 4 are formed in each of the plurality of first hole portions 3. As shown in FIG. 1, the plurality of slit portions 4 are formed in a substantially V-shape in which the outer peripheral surface 2A side of the float body 2 is the widest and gradually becomes narrower toward the inner peripheral surface 3A of the first hole portion 3. Has been.

As shown in FIG. 2, the blood component storage container 6 includes a storage container body 15 that is vertically long and open at one end, a cap 7 that is fitted into the opening of the storage container body 15, and the other end of the storage container body 15. And a component collection port 12 provided on the side.
The storage container body 15 stores liquid blood components such as serum. The cap 7 is provided with a blood component introduction passage 8 formed by a through-hole penetrating from the upper surface to the lower surface of the cap 7 and a ventilation passage 9 through which air enters and leaves the blood component storage container 6.

  One end of a connection tube 10 is connected to the blood component introduction path 8, and blood components such as serum are introduced into the blood component storage container 6 through the connection tube 10. One end side of a ventilation tube 11 is connected to the ventilation path 9, and a filter (not shown) having a property of allowing gas to pass but not liquid or bacteria to pass through the other end side of the ventilation tube 11. It is connected. The connection tube 10 and the ventilation tube 11 are melted and welded and closed after a predetermined amount of blood components are filled in the blood component storage container 6. As a result, the sterility of the blood component stored in the blood component storage container 6 is maintained.

  The component collection port 12 is used when collecting a blood component stored in the blood component storage container 6. The component collection port 12 has a first hollow cylindrical portion 12A having a small diameter that extends integrally downward from the other end side of the blood component storage container 6 and a slightly larger diameter than the first hollow cylindrical portion 12A, and a lower end is opened. A large-diameter second hollow cylindrical portion 12B and a cover 13 for closing the opening of the second hollow cylindrical portion 12B are provided. The cover 13 is integrally provided with an opening / closing operation piece 14 that protrudes to the side of the component sampling port 12.

  Next, using the float 1 for warming treatment in water according to the first embodiment, the blood component such as serum contained in the blood component storage container 6 in the state shown in FIG. (A treatment for inactivating the complement in blood components such as serum by immersing in for 30 minutes) will be described with reference to FIGS.

  First, the blood component storage container 6 is turned upside down as shown in FIGS. Next, the first hollow cylindrical portion 12A of the component collection port 12 in the blood component storage container 6 inverted in the vertical direction is brought into contact with the outer peripheral surface 2A of the float body 2 so as to be positioned at the wide opening of the slit portion 4. After the alignment, the blood component storage container 6 is pushed and moved along the slit portion 4. By this pushing movement, the slit portion 4 is sequentially deformed in the direction of widening the width, so that the first hollow cylindrical portion 12A in the blood component storage container 6 moves through the slit portion 4 and is transferred into the first hole portion 3. The When the first hollow cylindrical portion 12A in the blood component storage container 6 is completely moved into the first hole portion 3, the slit portion 4 returns to the original substantially V shape, and the first hollow cylinder is returned along with this return. The outer peripheral surface portion of the portion 12 </ b> A is sandwiched by the inner peripheral surface portion of the first hole portion 3. Thereby, the blood component storage container 6 is stably held by the float body 2.

  In the same manner as described above, as shown in FIGS. 3 and 4, the blood component storage container 6 is sandwiched in each of the four first holes 3 of the float body 2, and four floats 1 are used for the underwater warming treatment float 1. The blood component storage container 6 is held. At this time, a test tube or a microtube other than the blood component storage container 6 may be sandwiched in the second hole portion 5 having a large diameter as necessary.

  After the above preparatory work is completed, the float main body 2 is floated on the water surface, and the component storage portions of the four blood component storage containers 6 are immersed in the heated water. Thereby, the inactivation treatment (56 ° C. × 30 minutes) is performed on the blood component (serum) stored in each blood component storage container 6 to inactivate the complement in the blood component (serum).

The underwater warming treatment float 1 according to the first embodiment having the above-described configuration has the following effects.
A slit portion 4 is provided that can be deformed so as to allow passage of the blood component storage container 6 from the outer peripheral surface 2A of the float body 2 toward the inner peripheral surface 3A of the first hole portion 3. As a result, the blood component is accommodated in a shape in which a portion (the second hollow cylindrical portion 12B and the cover 13) having a larger diameter than the outer peripheral surface portion (first hollow cylindrical portion 12A) sandwiched by the first hole 3 is present at one end. Even in the case of the container 6, the first hollow cylindrical portion 12 </ b> A can be inserted into the first hole portion 3 and held therebetween. Therefore, there is no restriction on the shape of the container to be held, and versatility can be improved.

  The float main body 2 is provided with four (plural) first hole portions 3 and slit portions 4. As a result, the four (multiple) blood component storage containers 6 can be held in the float body 2, and the four (multiple) blood component storage containers 6 can be deactivated simultaneously. Therefore, the efficiency of the deactivation process can be increased.

  Moreover, the slit part 4 was formed in substantially V shape. As a result, when the blood component storage container 6 is pushed and moved from the outer peripheral surface 2A side of the float body 2 into the first hole 3, the slit portion 4 is easily deformed in the direction of increasing the width. A pushing operation for holding the container 6 in the first hole 3 can be easily performed. Further, when the first hollow cylindrical portion 12A of the blood component storage container 6 is positioned in the first hole portion 3, the narrow portion close to the inner peripheral surface 3A of the first hole portion 3 due to the shape restoration of the slit portion 4. Is sealed. Thereby, the outer peripheral part of the first hollow cylindrical part 12A of the blood component storage container 6 can be strongly held by the inner peripheral surface 3A of the first hole part 3.

  In addition, the float body 2 is provided with a second hole portion 5 for holding a test tube or a microtube other than the blood component storage container 6. Thereby, the versatility of the float 1 for underwater heating treatment can be further improved.

  Next, 2nd Embodiment-5th Embodiment of the float 1 for the underwater heating process of this invention is described. About these 2nd Embodiment-5th Embodiment, a different point from 1st Embodiment mentioned above is mainly demonstrated, the same point attaches | subjects the same code | symbol and abbreviate | omits description. For the points that are not particularly described, the description of the first embodiment is applied as appropriate.

  As shown in FIG. 5, the float 1 for underwater warming treatment of the second embodiment extends from the outer peripheral surface 2 </ b> A of the float main body 2 to the inner peripheral surface 3 </ b> A of the first hole portion 3 formed at four locations of the float main body 2. The slit part 4 that is formed to face is different from the first embodiment in that it is formed in a straight line having a narrow width over the entire length.

  According to the underwater warming treatment float 1 of the second embodiment, since the area of the slit portion 4 penetrating the float body 2 in the thickness direction is reduced, the buoyancy is increased compared to the first embodiment. It is possible to stabilize the floating posture of the float 1 and the holding posture of the blood component storage container 6 during the inactivation process.

  As shown in FIG. 6, the float 1 for underwater warming treatment of 3rd Embodiment arrange | positions the float main body 2 continuously in the circumferential direction by four circular-arc-shaped outer peripheral surface parts 2A1 with a central angle of about 270 degrees. It differs from 1st Embodiment by the point comprised in the shape which has the outer peripheral surface made. In other words, the underwater warming treatment float 1 of the third embodiment has a substantially four-leaf clover shape in plan view. This underwater warming treatment float 1 has four insertion portions 2A2 formed by the ends of the outer peripheral surface portions 2A1 and 2A1 adjacent to each other on the outer peripheral surface of the float body 2 in the circumferential direction. Further, the four first holes 3 are formed at respective positions on a line connecting the insertion portion 2A2 and the center portion of the float body 2 and close to the center portion of the float body 2. Further, the slit portions 4 are formed from the insertion portion 2A2 toward the inner peripheral surface 3A of the first hole portion 3, respectively.

  Each of the four outer peripheral surface portions 2A1 is preferably constituted by an arc in a circle having a diameter of 30 mm to 50 mm, and more preferably constituted by an arc in a circle having a diameter of 40 mm.

  According to the underwater warming treatment float 1 of the third embodiment, the first hole 3 is formed at a position close to the center of the float body 2. Therefore, the balance of the center of gravity when the blood component storage container 6 is held in the first hole 3 can be stabilized.

Moreover, the float main body 2 was comprised including the four circular-arc-shaped outer peripheral surface parts 2A1. Thereby, when a wave is generated on the water surface in a state where the float main body 2 is floated on the water surface, the influence of this wave can be dispersed by the outer peripheral surface portion 2A1 configured by an arcuate curved surface. The swing of the float 1 can be reduced. Therefore, the stability of the posture of the underwater warming treatment float 1 on the water surface can be further improved.
In addition, since the distance from the position of the first hole 3 to which the load is applied by the blood component storage container 6 toward the outer periphery of the float body 2 can be configured without making a large difference in all directions, the first hole 3 The balance of the center of gravity when the blood component storage container 6 is held in the can can be stabilized.

In addition, the operability when the blood component storage container 6 is inserted into the first hole 3 and when the blood component storage container 6 is detached from the first hole 3 can be improved.
That is, when the blood component storage container 6 is inserted into the first hole portion 3, first, one of the four outer peripheral surface portions 2A1 is grasped from both sides by, for example, the thumb and forefinger or middle finger. In this state, the blood component storage container 6 is applied to the insertion portion 2A2 and pushed inward, whereby the slit portion 4 can be easily opened and the blood component storage container 6 can be inserted into the first hole 3.
On the other hand, when detaching the blood component storage container 6 from the first hole 3, the blood component storage container 6 is placed on the side of the insertion portion 2A2 while holding one of the four outer peripheral surface portions 2A1 from both sides. By pushing outward (outside), the slit portion 4 can be easily opened and easily detached from the first hole portion 3 of the blood component storage container 6. That is, according to the third embodiment, since the slit portion 4 is provided in the insertion portion 2A2 formed between the adjacent outer peripheral surface portions 2A1, a force can be easily applied in the direction in which the slit portion 4 is opened.

  Moreover, the float 1 for underwater heating processing was comprised including the four outer peripheral surface parts 2A1. Therefore, since the underwater heating treatment float 1 has a four-leaf clover-like appearance, it is excellent in aesthetic appearance.

  Further, the float 1 for underwater warming treatment was configured to be point-symmetric with the center of the float body 2 as the symmetry point. Therefore, even when the float body 2 is subjected to an external force load such as a wave, the float body 2 can be prevented from swinging in a specific direction, so that the stability of the underwater warming treatment float 1 on the water surface is stable. Can be further improved.

  FIG. 7 is a view showing a first modification of the underwater warming treatment float 1 of the third embodiment. The underwater warming treatment float 1 of the first modification is different from the underwater warming treatment float of the third embodiment mainly in that the first hole 3 is formed so as to be in contact with the insertion portion 2A2.

  More specifically, the first hole portion 3 is formed inside the insertion portion 2A2 between the insertion portion 2A2 and the center portion of the float body 2. That is, in the first modification, the length of the slit portion 4 is configured to be extremely short (for example, less than 3 mm). The slit portion 4 is in a closed state in a normal state where no external force is applied to the float body 2. And the 1st hole 3 is comprised by the circular shape which does not lack in planar view in the state which the slit part 4 closed.

  Moreover, as shown in FIG. 7, the external shape of the underwater warming treatment float 1 of the first modification has a shape in which four circles having the same diameter (for example, a diameter of 40 mm) are in contact with each other. Therefore, in the underwater warming treatment float 1 of the first modification, the four inlet portions 2A2 are closer to the center of the float body 2 than the underwater warming treatment float 1 of the third embodiment. Has been placed. As a result, the four first holes 3 formed so as to be in contact with the insides of the four insertion portions 2 </ b> A <b> 2 are also arranged near the center of the float body 2.

More specifically, in the first modification, the four first hole portions 3 are formed in a circular shape having a diameter of 8 mm, and the two first hole portions 3 that face each other with the center portion of the float main body 2 interposed therebetween. The distance L1 between the centers is 32 mm. Further, the length L2 in the direction along the direction connecting the two opposing first holes 3 in the float body 2 is 80 mm.
Here, when the blood component storage container 6 is held in the first hole 3, the distance L1 between the centers of the two first holes 3 facing each other across the center of the float body 2, and the float body 2 The relationship (L1 / L2 (%)) with the length L2 in the direction along the direction connecting the two opposing first hole portions 3 is preferably in the range of 25% to 50%, and preferably from 35% to 45%. % Is more preferable. If the relationship between L1 and L2 exceeds 50%, the balance of the center of gravity of the float main body 2 may not be maintained better. Further, if the relationship between L1 and L2 is less than 25%, for example, when the blood component storage container 6 is held in the plurality of first holes 3, there is a possibility that interference by each blood component storage container 6 occurs. is there.

  According to the underwater warming treatment float 1 of the first modification, the first hole 3 is formed so as to be in contact with the insertion portion 2A2. Thereby, since the length of the slit part 4 can be configured to be short, the operability when the blood component storage container 6 is inserted into the first hole part 3 and when the blood component storage container 6 is detached can be improved. Moreover, the slit part 4 was comprised so that it might close in a normal state. Therefore, the clamping property of the blood component storage container 6 by the 1st hole 3 can be improved.

  In addition, the outer shape of the underwater warming treatment float 1 was formed in a shape in which four circles were in contact with each other. Thereby, since the position of the insertion part 2A2 can be arrange | positioned in the more center part side of the float main body 2, the 1st hole part 3 formed so that the contact part 2A2 may be contacted may be a position closer to the center part of the float main body 2 Can be placed. Therefore, the balance of the center of gravity when the blood component storage container 6 is held in the first hole 3 can be further stabilized.

FIG. 8 is a diagram illustrating a second modification of the underwater heating treatment float 1 according to the third embodiment. The underwater warming treatment float 1 according to the second modification differs from the underwater warming treatment float 1 according to the first modification in the shape of the outer peripheral surface portion 2A1.

Accordingly, in the underwater warming treatment float 1 of the second modification, the four inlet portions 2A2 are further closer to the center of the float body 2 than the underwater warming treatment float 1 of the first modification. Are arranged. As a result, the four first holes 3 formed so as to be in contact with the insides of the four insertion portions 2 </ b> A <b> 2 are also arranged near the center of the float body 2. More specifically, in the second modification, the four first hole portions 3 are formed in a circular shape having a diameter of 8 mm, and the two first hole portions 3 that face each other with the center portion of the float body 2 interposed therebetween. The distance L3 between the centers is 20 mm. Moreover, the length L4 in the direction along the direction connecting the two opposing first holes 3 in the float body 2 is 80 mm.

  Note that the distance L3 between the centers of the two first holes 3 facing each other across the center of the float body 2 is 20 mm or more from the viewpoint of stably holding the blood component storage container 6 in the first hole 3. It is preferable that When the distance L3 between the centers of the two first holes 3 facing each other across the center of the float body 2 is less than 20 mm, the blood component storage container 6 sandwiched between the two first holes 3 is There is a risk of interference.

  According to the underwater heating treatment float 1 of the second modified example, the outer peripheral surface portion 2A1 is formed in a substantially elliptical shape in which a straight line connecting the top portion and the center portion of the float body has a long diameter. Thereby, since the position of the insertion part 2A2 can be arranged on the further central side of the float body 2, the first hole 3 formed so as to be in contact with the insertion part 2A2 is further closer to the center part of the float body 2 Can be placed. Therefore, the balance of the center of gravity when the blood component storage container 6 is held in the first hole 3 can be further stabilized.

  Further, the distance L3 between the centers of the two first hole portions 3 facing each other with the center portion of the float body 2 interposed therebetween is configured to be 20 mm or more. Therefore, interference of the blood component storage container 6 sandwiched in the first hole 3 while stabilizing the balance of the center of gravity of the underwater warming treatment float 1 when the blood component storage container 6 is held in the first hole 3. Can be prevented.

  According to the underwater heating treatment float 1 of the fourth embodiment, the four first hole portions 3 are formed in the middle of the spiral slit portion 4. Thereby, for example, when one or two blood component storage containers 6 are held on the float body 2 and used, the blood component storage container 6 in consideration of the center of gravity balance is inserted into the first hole 3 at an arbitrary position. Be held.

  In the fourth embodiment, as shown in FIG. 9, the first hole 3 is configured in a substantially circular shape by matching two substantially semicircular holes divided by the slit 4. Not limited to this. That is, as shown in FIG. 10, the first hole 3 may be provided such that one portion of the periphery of the substantially circular first hole 3 is in contact with the slit portion 4. Thereby, the retainability of the blood component storage container 6 by the 1st hole 3 can be improved.

As shown in FIG. 11, the float 1 for underwater warming treatment of the fifth embodiment includes a float main body 2, a circular central float portion 23 including the central portion of the float main body 2, and an outer periphery of the central float portion 23. It can be divided into a square-shaped outer peripheral float portion 24 that surrounds. A circular hole 231 is formed in the central portion of the outer peripheral float portion 24 so that the central float portion 23 can be fitted, held, and detached.
