JP 2003-149234 A

  As described above, the conventional blood dilution container is configured to remove the cap of the container in which the diluent is added, add blood, attach the cap again, and invert the container to mix. In this configuration, blood with a high viscosity is added to a diluent with a low viscosity, so that when blood is added, the blood stays at a fixed position without being mixed with the diluent. Therefore, if the container is not shaken many times, the blood and the diluted solution will not be sufficiently mixed. Therefore, an object of the present invention is to provide a blood dilution container that can sufficiently mix blood and a diluent without shaking the container as much as a conventional product.

  In addition, the conventional blood dilution container is configured such that blood is removed from the container containing the diluent and added from the outside, so the container tilts and spills the diluent when the cap is removed or when blood is added. There is a fear. Accordingly, an object of the present invention is to provide a blood dilution container that does not spill dilution liquid even when the container is tilted.

  Claim 1 of the present invention includes a container main body, an enclosure enclosing a diluent, and a cutter, the enclosure being rotatable about its central axis, and the fixed cutter being an enclosure The structure is characterized in that the dilution liquid outlet is cut open by being pressed against the enclosure by rotation. According to a second aspect of the present invention, before the enclosure is rotated, the enclosure is not in contact with the cutter, and the blade of the cutter comes into contact with the enclosure by rotating the enclosure around the central axis of the enclosure. An element in which the cutter opens the outlet by rotating the enclosure is limited to claim 1.

Claim 3 is a lid of the container main body in which the enclosure is coupled to the container main body by screwing, and an element in which a storage section for the diluent is provided on the back surface of the enclosure and the storage section is closed with a sheet is claimed. The configuration is limited to the first or second aspect.

According to a fourth aspect of the present invention, an upward cutter is attached to the inside of the container body, and when the enclosure is placed on the container body, the cutter does not contact the sheet, and the enclosure body is rotated to fill the container body. The element that opens the outlet after the cutter hits the sheet until the sheets are joined is limited to claim 3.

The fifth aspect of the present invention is limited to the fourth aspect, in which a blood receiving tray having a smaller area than that of the container main body is attached to the container main body, and the receiving tray has an element attached at a position for receiving the effluent diluent from the outlet. This is an added configuration. A sixth aspect of the present invention has a configuration in which the upper surface of the tray has a planar shape and is provided with a large number of grooves, and elements connected to these grooves are limitedly added to the fifth aspect.

According to a seventh aspect of the present invention, the enclosing body is made of a flexible material and is formed separately from the lid, and is attached to the lid so as to be rotatable with respect to the lid, and the cutter is attached to the lid. An element in which the enclosing body is cut open by the cutter by rotating the body is limited to claim 1 or claim 2.

According to the eighth aspect of the present invention, the portion to be cut by the cutter is formed in the lower portion of the enclosure, the portion to be cut is formed to be narrower than the portion above, and the cross-sectional shape of the portion to be cut is an oval shape. Before turning the body, the cutter is directed to the elliptical short-diameter portion, and an element for opening the long-diameter portion of the portion where the cutter is cut open by rotating the enclosure is limited to claim 7. It is a configuration.

According to a ninth aspect of the present invention, an upward cutter is attached to the inside of the container main body, and when the enclosure is placed on the container, the cutter contacts the enclosure to partially support the enclosure, The element that the cutter opens the outlet by rotating the enclosure around the central axis of the enclosure after being pushed down and stabbed into the enclosure is limited to claim 1.

Claim 1 includes a container body, an enclosure enclosing a diluent, and a cutter, and the enclosure is rotatable about its central axis, and the fixed cutter is rotated by the rotation of the enclosure. The structure is characterized in that the dilute solution outlet is cut open by being pressed against the enclosure. As a result, the blood is diluted while the diluent flows down from the diluent outlet on the blood put in the container body, so when the predetermined diluent flows out, the blood and the diluent are already mixed to some extent. Therefore, the blood and the diluent can be sufficiently mixed without shaking the container many times thereafter. Further, when blood is put into the container body and then the lid is closed and the enclosure is rotated by hand, the diluent outlet is cut open, and the diluent flows out of the outlet and flows into the container body to dilute the blood. Therefore, it is not a configuration in which blood is added from the outside into the diluent contained in the container as in the prior art, but the inclusion body is cut open and the diluent is allowed to flow into the container, so that mixing is performed inside the container. Even if the container is tilted, there is no risk that the diluent will spill.

According to a second aspect of the present invention, before the enclosure is rotated, the enclosure is not in contact with the cutter, and the blade of the cutter comes into contact with the enclosure by rotating the enclosure around the central axis of the enclosure. The cutter is configured to open the outlet by rotating the enclosure. Therefore, since the enclosing body is automatically opened only by rotating the enclosing body, instead of holding the cutter by hand, the cutting operation can be performed very easily.

The third aspect of the present invention is a lid of the container body in which the enclosure is coupled to the container body by screwing, and a storage unit for the diluent is provided on the back surface of the enclosure, and the storage unit is closed with a sheet. . Therefore, when the blood is put into the container body and the lid is attached, the sheet is automatically cut open and the diluent flows out, so that the blood and the diluent can be easily mixed in the container.

According to a fourth aspect of the present invention, an upward cutter is attached to the inside of the container body, and when the enclosure is placed on the container body, the cutter does not contact the sheet, and the enclosure body is rotated to fill the container body. In this configuration, the cutter hits the sheet until it is joined, and then opens the outlet. Therefore, since the diluent flows out and is mixed with blood only by the usual common operation of simply attaching a lid to the container body, anyone can easily perform it without requiring any special operation.

According to a fifth aspect of the present invention, a blood tray having a smaller area than that of the container body is attached to the container body, and the tray is attached to a position for receiving the effluent diluted liquid from the outlet. Accordingly, since the dilute solution that has flowed out is mixed with the blood so as to wash away the pan, the blood and the dilute solution are mixed to some extent just by letting out the dilute solution, and the subsequent mixing operation does not take time.

The sixth aspect of the present invention has a configuration in which the upper surface of the tray is flat and provided with a number of grooves, and these grooves are connected. Therefore, when blood is dropped onto the pan, the groove acts like a capillary, and the blood travels along the groove and spreads to the top of the plate. Will flow evenly. In other words, if the amount of blood required is the time when blood flows evenly into the sulcus and stains red as a whole, blood can be quantified using this tray.

According to a seventh aspect of the present invention, the enclosing body is made of a flexible material and is formed separately from the lid, and is attached to the lid so as to be rotatable with respect to the lid, and the cutter is attached to the lid. The enclosure is cut open by the cutter by rotating the body. Therefore, even if the cut for opening the inclusion body is small, the inclusion body has flexibility, so that it can be crushed. Therefore, by diluting the inclusion body, the diluent can be quickly poured out. Accordingly, it is not necessary to rotate the enclosure many times, and the diluent can be pushed out only by rotating 180 degrees at the maximum, so that the operation can be performed easily and quickly.

According to the eighth aspect of the present invention, a portion to be cut by the cutter is formed at a lower portion of the enclosure, the portion to be cut is formed to be narrower than a portion above the portion, and the cross-sectional shape of the portion to be cut is an ellipse, Before the body is rotated, the cutter is directed to the elliptical short diameter portion, and by rotating the enclosure, the cutter is configured to open the long diameter portion of the portion to be cut open. Therefore, when the cutter is facing the short diameter portion, the cutter does not touch the short diameter portion, but when the enclosure is rotated 90 to 180 degrees, the cutter reaches the long diameter portion, and the cutter hits the enclosure and encloses it Since the body is cut open, the diluted solution flows out by crushing the inclusion body. As a result, the diluted liquid can be discharged only by rotating the enclosure and crushing the enclosure, so that the operation can be performed quickly and easily.

According to a ninth aspect of the present invention, an upward cutter is attached to the inside of the container main body, and when the enclosure is placed on the container, the cutter contacts the enclosure to partially support the enclosure, After the cutter is pushed down and pierces the enclosure, the cutter opens the outlet by rotating the enclosure around the central axis of the enclosure. In this configuration, the attachment position of the upward cutter in claim 4 is set higher than the state of claim 4, or the length of the cutter is extended longer upward. Therefore, since the opening of the outlet is already started when the enclosure is pushed down and the cutter is pierced into the enclosure before the enclosure is rotated, a sufficient outlet can be provided even if the rotation angle of the enclosure is small. I can make it.

  Next, the best mode for carrying out the present invention will be described. The container 1 includes a container body 2 and a lid 3 that also serves as an enclosure for a diluent, and both are made of plastic. The container body 2 has a cylindrical shape, and a hole 4 is provided at the bottom and is closed by a closing portion 5. The closing part 5 can be provided with a waterproof sheet that can be broken relatively easily, or the closing part 5 can be formed integrally with the container body 2 and formed thinner than the container body 2 to make a hole relatively easily. You may be able to do it. Or you may attach so that it may remove | deviate from the hole 4 comparatively easily, when the closure part 5 is engage | inserted in the container main body 2, and the closure part 5 is pushed.

  The lower half of the container body 2 has an inner and outer diameter smaller than that of the upper half, and a screw portion 6 is provided on the upper portion of the lower half. Also, a screw portion 7 is provided at the lower part of the upper half of the container body 2, and a plastic tray 8 having a smaller area is attached to the upper half of the container body 2. The upper surface of the tray 8 is a flat surface, and the edge portion 9 is slightly raised. A large number of grooves 10 are formed on the upper surface, and these grooves 10 are all connected by a proximal end groove 11 extending in the lateral direction at the proximal end. ing. Therefore, even if the blood is not dropped evenly on the entire receiving tray 8, if the blood is dropped to a certain place, the blood is evenly distributed to the grooves 10 and 11 due to the capillary phenomenon of the groove 10 and the proximal groove 11. If the required amount of blood is set when the entire saucer is stained red, blood can be quantified in this saucer. Further, an elongated upward-facing cutter 12 adjacent to the proximal end groove 11 is formed integrally with the tray 8.

  A screw portion 13 is provided on the inner surface of the lid 3, and the lid 3 is coupled to the container main body 2 by screwing with the screw portion 7 of the container main body. The back surface of the lid 3 is provided with a diluting liquid sealing portion 14 and sealed with a waterproof sheet 15. The tip of the cutter 12 does not reach the sheet 15 before the lid 3 is mounted on the container body 2 and the screw 7 and screw 13 are started to be screwed together. When the lid 3 is rotated and the screwing operation is started, the lid 3 is lowered, the cutter 12 is stabbed into the sheet 15, and the sheet 15 can be broken by further rotating the lid 3.

  Next, the usage method of this embodiment is demonstrated. First, blood obtained by piercing a finger or the like with a lancet using a lancet is dropped onto the receiving pan 8, and the supply of blood is stopped when the entire upper surface of the receiving pan 8 is stained red. Then, the lid 3 is put on the container body 2 and rotated. When the lid 3 is completely connected to the container body 2, the container 1 is inverted and the blood and the diluent are mixed.

  When mixing is completed, the container 1 is attached to the separator 16 as shown in FIG. The separator 16 has an attachment portion 17 for the container 1, and a screw portion 18 that is screwed with the screw portion 6 of the container 1 is provided. An upward cutter 19 is provided at the center of the bottom of the mounting portion 17, and a through hole 20 is formed around the cutter 19. The main body of the separator 16 is formed in a cylindrical shape, and an inlet 21 is provided below the attachment portion 17 so that diluted blood in the separator 16 flows into the main body of the separator 16. .

  After mixing the blood and the diluted solution by inverting the container 1 or the like, the container 1 is attached to the attachment portion 17 by screwing while rotating. During this screwing, the cutter 19 breaks the blocking portion 5, and diluted blood flows into the storage chamber 22 through the passage 20 and the inlet 21. A piston 23 having a sealing function is built in the storage chamber 22, and a filter 24 is mounted on the side facing the piston 23. By pulling the plunger 26, the piston 23 is rubbed in the direction of the filter 24, and the diluted blood in the storage chamber 22 is filtered by the filter 24, sent to the collection chamber 27 through the check valve 27, and collected.

  6 and 7 show another embodiment. The enclosure 28 is formed of a flexible plastic in a fan shape, and a diluent is enclosed therein. The base 29 of the enclosure is formed in an elliptical cross section, and the mouth is sealed with a plug 30. Since the cross section of the mouth portion is oval, the cross section of the plug 30 that seals the mouth portion is oval. However, the cross section of the plug 30 that protrudes from the mouth portion is circular, and the cross section of the plug 30 is circular. This portion is attached to the lid 31 so as to be rotatable with respect to the lid 31. Two lids 36 are attached to the lid 31 so as to face the short diameter portion of the base 29 of the enclosure. FIG. 6 shows this state, and shows a cross section obtained by cutting the short diameter portion of the elliptical base portion 29.

  The plug 30 of the enclosure is rotatably fitted in the center of the lid 31 and has a plurality of through holes 32 around it. The lid 31 is coupled to the container main body 33 by screwing, and the container main body 33 is coupled to the separator 34 by screwing. Prior to use, the container body 33 and the separator 34 are not coupled. When the container is used, blood obtained by inserting a needle into a finger or the like using a lancet is put into the container body 33. At this time, the hole provided in the bottom of the container body 33 is closed by the closing portion 35. Next, the lid 31 is completely attached to the container main body 33, and the enclosure 28 is rotated 90 to 180 degrees. Since the base 29 is elliptical, when the enclosure 28 is rotated, the long diameter portion of the base 29 hits the cutter 36 and is cut open. Then, the enclosure 28 is crushed and the diluent is poured into the container body 33 through the through-hole 32 to dilute the blood.

  Next, the container main body 33 is attached to the attachment portion 37 of the separator by screwing. When the container body 33 is attached to the attachment portion 37, the cutter 40 breaks the closing portion 35 and diluted blood flows into the separator 34. Therefore, by pulling the plunger, the diluted blood is filtered by the filter 41 to separate the plasma. 6 is for screwing a cover (not shown) having a screw portion for closing the attachment portions 17 and 37 before use. . The screw portion 38 provided in the mounting portion 17 shown in FIG. 4 has the same purpose. Reference numeral 42 denotes a housing in which a main body portion of the separator 34 is housed.
