Further, a screw thread 15 b and a screw groove 15 c are formed on the outer peripheral surface of the first cap 15. In the embodiment shown in FIG. 2, a gap is present between the first seal member 14 and the first cap 15, but the gap may not be present.

  FIG. 3 is an enlarged cross-sectional view of the first housing member 21. As shown in FIG. 3, a first hollow needle 22 is attached to the first housing member 21. In FIG. 3, one open end of the first delivery pipe 2 is attached to the first housing member 21. The inside of the first hollow needle 22 communicates with the inside of the first delivery pipe 2. The manner in which the first hollow needle 22 is attached to the first housing member 21 is not limited to that shown in FIG. 3. For example, the first hollow needle 22 is attached to the first hollow needle 22 via various adapters. It can be attached to one housing member 21. In the embodiment shown in FIG. 3, the first delivery pipe 2 is directly connected to the first housing member 21, but the first delivery pipe 2 is connected to the first housing member 21 via various adapters. You may connect.

  In the embodiment shown in FIG. 3, the first housing member 21 has an internal space 21a. And the thread 21b and the screw groove 21c are formed in the internal peripheral surface of the 1st housing member 21 which comprises the internal space 21a. The distal end of the first hollow needle 22 exists in the internal space 21 a of the first housing member 21. The shape of the first housing member 21 is not particularly limited as long as it has the internal space 21a, and can be various forms such as a cylindrical shape, a spherical shape, a rectangular parallelepiped shape, a cubic shape, and a bag shape.

  FIG. 4 is a view showing an embodiment of the first housing member 21 and the first cap 15, and the arrows indicate the first housing member 21 and the first cap 15 (in the portions indicated by the arrows). Each cross section of is shown. In the embodiment shown in FIG. 4, the thread 21 b and the screw groove 21 c on the inner peripheral surface of the first housing member 21 and the thread 15 b and the screw groove 15 c on the outer peripheral surface of the first cap 15 can be engaged. . And as shown to Fig.4 (a), the convex part 21d which has a slope and a vertical surface is formed in a part of screw thread of the opening edge part (downward drawing) of the 1st housing member 21, The one Thus, as shown in FIG. 4B, a concave portion 15d having a slope and a vertical surface and a pin 15e are formed in a part of the screw groove on the outer peripheral surface of the uppermost portion (upward in the drawing) of the first cap 15. ing.

  FIG. 5 shows the assembly of the kit of the present invention in the embodiment shown in FIG.

  When assembling the kit of the present invention of the embodiment shown in FIG. 4, first, as shown on the left side of FIG. 5, the open end portion of the first housing member 21 and the uppermost portion of the first cap 15 face each other. Next, as shown on the right side of FIG. 5, the threads and screw grooves at the open end of the inner peripheral surface of the first housing member 21 and the uppermost threads and screws of the outer peripheral surface of the first cap 15. Engage the grooves. As described above, the first housing member 21 and the first cap 15 are engaged, so that the first housing member 21 surrounds the discharge port 11 a of the syringe 11, and the internal space of the first housing member 21. 21a becomes a closed space isolated from the outside, and isolates the first hollow needle 22 and the discharge port 11a from the surrounding environment. That is, a closed space is formed around the discharge port 11a. The closed space is preferably airtight. The closed space preferably maintains a closed state.

  By forming the closed space (21a) by the engagement of the first housing member 21 and the first cap 15, the assembly of the kit of the present invention is completed. The first hollow needle 22 exists in the closed space (21a) in the assembled kit of the present invention shown in FIG. 5, and a part of the first seal member 14 (the discharge port 11a is sealed). Part) is exposed to the closed space (21a). However, the 1st hollow needle 22 (especially front-end | tip) and the 1st sealing member 14 are spaced apart in the closed space (21a).

  The assembly of the kit is completed by forming a closed space by the engagement of the first housing member 21 and the first cap 15.

  In this way, the parts constituting the kit of the present invention are assembled to form the kit of the present invention. By assembling the kit, the first container 1 and the first housing member 21 are integrated. Therefore, the kit of the present invention shown in FIG. 1 includes the first container 1 and the first housing member 21. In the embodiment of FIG. 1, the first housing member 21 is connected to the first delivery pipe 2, and after the first container 1 and the first housing member 21 are assembled, the discharge of the first container 1 is performed. The outlet 11a can communicate with the open end of the first delivery pipe 2 (however, the discharge port 11a is sealed by the first seal member 14, and the first hollow needle 22 and the first seal member 14 are separated from each other). doing).

  In engaging the first housing member 21 and the first cap 15, it is preferable that the fluctuation of the relative position between the first housing member 21 and the first cap 15 is limited after the engagement. As a result, the engagement between the first housing member 21 and the first cap 15 is disengaged due to, for example, vibration generated during the transportation of the kit of the present invention, and the closed state of the closed space (21a) is impaired. It can be avoided.

  Therefore, it is preferable that the kit of the present invention includes a stopper mechanism that restricts fluctuations in the relative positions of the first housing member 21 and the first cap 15.

  FIG. 6 is a view showing a stopper mechanism in the kit of the present invention of the embodiment shown in FIG. 4, and is a schematic sectional view seen from the first cap 15 side.

  As described above, in the kit of the present invention shown in FIG. 4, a convex portion 21 d having a slope and a vertical surface is formed on a part of the thread provided on the inner peripheral surface of the first housing member 21. On the other hand, a recess 15d having a slope and a vertical surface and a pin 15e are formed in a part of the screw groove on the outer peripheral surface of the first cap 15. The convex portion 21d and the concave portion 15d constitute a first stopper mechanism, and the convex portion 21d and the pin 15e constitute a second stopper mechanism.

  When the first housing member 21 and the first cap 15 are engaged as shown in FIG. 5, the convex portion 21d of the first housing member 21 and the concave portion 15d of the first cap 15 are as shown in FIG. As a result, the variation in the relative position of the first housing member 21 and the first cap 15 is limited. Moreover, the fluctuation | variation of the relative position of the 1st hollow needle 22 and the 1st cap 15 is also restrict | limited.

  In the aspect shown in FIG. 6, when the first cap 15 is used as a reference, the rightward rotation of the first housing member 21 is limited, and only the leftward rotation is allowed. Therefore, once the first housing member 21 and the first cap 15 are engaged and the convex portion 21d of the first housing member 21 and the concave portion 15d of the first cap 15 are engaged with each other, the first housing member 21 is The rotation in the direction away from the first cap 15 is restricted, and the first housing member 21 can rotate only in the direction of further engagement with the first cap 15.

  Thereby, for example, in the engaged state shown on the right side of FIG. 5, the first housing member 21 is allowed only to move downward, and the first cap 15 is allowed only to move upward. . That is, the first stopper mechanism allows the relative position of the first housing member 21 and the first cap 15 to change only in the direction in which the volume of the closed space (21a) decreases. Therefore, the relative position of the first hollow needle 22 and the first seal member 14 can be changed only in the direction in which the volume of the closed space (21a) decreases. In other words, the relative position of the first hollow needle 22 and the first seal member 14 can be changed only in the direction in which the tip of the first hollow needle 22 penetrates the first seal member 14. .

  In the embodiment shown in FIG. 6, the pin 15e temporarily blocks the movement of the convex portion 21d, so the second stopper mechanism temporarily fixes the relative position of the first housing member 21 and the first cap 15. Therefore, the relative positions of the first hollow needle 22 and the first seal member 14 are also temporarily fixed.

  However, in the embodiment shown in FIGS. 4 to 6, the pin 15 e is made of a flexible member such as soft resin or rubber and can be bent, so that the convex portion 21 d is brought into contact with the pin 15 e, and By applying force, the pin 15e can be bent and the convex portion 21d can get over the pin 15e. Therefore, although the pin 15e temporarily prevents the movement of the convex portion 21d, for example, when the user applies a force to rotate the first housing member 21 in the left direction of FIG. 6, the convex portion 21d causes the pin 15e to move. It can be bent and moved to the left over the pin 15e. Thereby, the first housing member 21 can also rotate leftward.

  That is, the relative position between the first housing member 21 and the first cap 15 is fixed by the second stopper mechanism when not in use, and the relative position between the first hollow needle 22 and the first seal member 14 is also fixed. However, in use, the fixing of the relative positions of the first housing member 21 and the first cap 15 is released. Then, due to the action of the first stopper mechanism, the relative position of the first housing member 21 and the first cap 15 varies only in the direction in which the closed space (21a) decreases, and as a result, the first hollow needle 22 is changed. The relative position of the first seal member 14 also varies only in the direction in which the closed space (21a) decreases. In other words, the first hollow needle 22 and the first seal member 14 are such that the first hollow needle 22 approaches the first seal member 14 and the tip of the first hollow needle 22 is the first seal. The relative position varies only in the direction in which the member 14 is pierced.

  In this manner, the first stopper mechanism disengages the first housing member 21 and the first cap 15 due to vibration during transportation, for example, when the kit of the present invention is not used, and the closed space (21a ) Is closed, and it is avoided that the assembled state of the kit of the present invention is released.

  Further, the second stopper mechanism allows the relative position between the first housing member 21 and the first cap 15, that is, the first hollow needle 22 and the first seal member, for example, when the kit of the present invention is not used. 14 is prevented from changing, and the first hollow needle 22 is prevented from being pierced through the first seal member 14 by mistake when not in use.

  4 to 6, the pin 15e can be bent with a soft member such as a soft resin or rubber. For example, the pin 15e is made of a resin having a strength that can be broken by human power. May be. In this case, in use, a force in the rotational direction is applied to the first housing member 21 or the first cap 15, and the pin 15 is broken by contact and pressing with the convex portion 21 d, so that the first housing member 21 and the first cap 15 The relative position with respect to one cap 15 may be variable.

  FIG. 7 is a view showing another example of a stopper mechanism in the kit of the present invention.

  In the embodiment shown in FIG. 7, a convex portion 21 e having a curved surface is formed on a part of the thread provided on the inner peripheral surface of the first housing member 21, while the outer periphery of the first cap 15 is formed. Convex portions 15f and 15g having curved surfaces are also formed in part of the surface screw grooves. And the convex part 21e and the convex part 15g comprise the 1st stopper mechanism, and the convex part 21e and the convex part 15f comprise the 2nd stopper mechanism. In addition, in the aspect shown in FIG. 7, it is preferable that the height of the convex part 15g is higher than the height of the convex part 15f.

  In the embodiment shown in FIG. 7, the convex portion 21e cannot overcome the convex portions 15f and 15g naturally, but can be overcome by applying force. The material, shape, and size of the convex portions 21e, 15f, and 15g are such that the convex portion 21e can get over the convex portions 15f and 15g by applying a force, and the convex portion 21e naturally has the convex portion 15f. And 15 g are not particularly limited. For example, the convex portion 21e can be composed of a relatively flexible member such as plastic, soft resin, or rubber, and 15f and 15g can be composed of a member such as a relatively strong resin. A shape of a part of a sphere such as a shape can be provided.

  Then, when the first housing member 21 and the first cap 15 are engaged as shown in FIG. 7, the convex portion 21e of the first housing member 21 and the convex portions 15f and 15g of the first cap 15 are fitted. As a result, the fluctuation of the relative position between the first housing member 21 and the first cap 15 is limited. Moreover, the fluctuation | variation of the relative position of the 1st hollow needle 22 and the 1st cap 15 is also restrict | limited.

  In particular, as shown in FIG. 8, when the convex portion 21e has a partial vertical surface, and the convex portion 15g has a partial vertical surface, the vertical surfaces are engaged with each other. When the first cap 15 is used as a reference, the rightward rotation of the first housing member 21 is restricted, and only the leftward rotation is allowed. Therefore, when the first housing member 21 and the first cap 15 are engaged, the rotation of the first housing member 21 in the direction away from the first cap 15 is restricted, and the first housing member 21 is It is possible to rotate only in the direction of further engagement with the cap 15.

  Thus, in the engaged state shown in FIG. 8, the first housing member 21 is allowed only to move downward, and the first cap 15 is allowed only to move upward. That is, the first stopper mechanism allows the relative position of the first housing member 21 and the first cap 15 to change only in the direction in which the volume of the closed space (21a) decreases. Therefore, the relative position of the first hollow needle 22 and the first seal member 14 can be changed only in the direction in which the volume of the closed space (21a) decreases. In other words, the relative position of the first hollow needle 22 and the first seal member 14 can be changed only in the direction in which the tip of the first hollow needle 22 penetrates the first seal member 14. .

  Moreover, in the aspect shown in FIG.7 and FIG.8, since the convex part 15f blocks | prevents the movement of the convex part 21e, the 2nd stopper mechanism changes the relative position of the 1st housing member 21 and the 1st cap 15. FIG. Temporarily fix. Therefore, the relative positions of the first hollow needle 22 and the first seal member 14 are also temporarily fixed.

  However, in the embodiment shown in FIG. 7 and FIG. 8, the convex portion 21e is made of a member such as plastic or rubber, and it is possible to get over the convex portion 15f by applying a force. The convex part 21e can get over the convex part 15f by bringing 21e into contact with the convex part 15f and applying further force. Accordingly, the convex portion 15f temporarily prevents the movement of the convex portion 21e. For example, when the user applies a force to rotate the first housing member 21 in the left direction in FIGS. 7 and 8, the convex portion 21e. Can move over the convex portion 15f and move leftward. Thereby, the first housing member 21 can also rotate leftward.

  That is, the relative position between the first housing member 21 and the first cap 15 is fixed by the second stopper mechanism when not in use, and the relative position between the first hollow needle 22 and the first seal member 14 is also fixed. However, in use, the fixing of the relative positions of the first housing member 21 and the first cap 15 is released. Then, due to the action of the first stopper mechanism, the relative position of the first housing member 21 and the first cap 15 varies only in the direction in which the closed space (21a) decreases, and as a result, the first hollow needle 22 is changed. The relative position of the first seal member 14 also varies only in the direction in which the closed space (21a) decreases. In other words, the first hollow needle 22 and the first seal member 14 are such that the first hollow needle 22 approaches the first seal member 14 and the tip of the first hollow needle 22 is the first seal. The relative position varies only in the direction in which the member 14 is pierced.

  In this manner, the first stopper mechanism disengages the first housing member 21 and the first cap 15 due to vibration during transportation, for example, when the kit of the present invention is not used, and the closed space (21a ) Is closed, and it is avoided that the assembled state of the kit of the present invention is released.

  Further, the second stopper mechanism allows the relative position between the first housing member 21 and the first cap 15, that is, the first hollow needle 22 and the first seal member, for example, when the kit of the present invention is not used. 14 is prevented from changing, and the first hollow needle 22 is prevented from being pierced through the first seal member 14 by mistake when not in use.

  When the kit of the present invention of the embodiment shown in FIGS. 1 to 8 is used after assembly, the first hollow member 22 and the first seal member are rotated by rotating the first housing member 21 or the first cap 15. 14, the first hollow needle 22 is moved closer to the first seal member 14, passed through the opening 15 a of the first cap 15, and the first hollow needle 22 is moved to the first end by the first hollow needle 22. The seal member 14 is pierced.

  By the piercing of the first seal member 14 by the first hollow needle 22, the tip of the first hollow needle 22 reaches the discharge part 11 a of the syringe 11, and the space 1 a in the syringe 11 is the first delivery pipe 2. Communicates with the interior of As a result, the first fluid in the space 1a can be sent out of the first container 1 via the first hollow needle 22, and the first fluid is transferred to the first delivery pipe by moving the plunger 13. 2 is sent out.

  In the kit of the present invention, since the first seal member 14 is pierced by the first hollow needle 22 in the closed space (21a), fine contaminants such as bacteria in the surrounding environment are not used during use. 1 is not mixed into the fluid. Thus, the kit of the present invention can provide hygienically delivery of the first fluid.

  In the kit of the present invention, since the first container 1 and the first housing member 21 are connected in advance, it is not necessary to connect the first container 1 and the first housing member 21 during use. Therefore, the delivery work can be performed in a sanitary manner, and it is not necessary to perform the connection work at the time of use.

  Therefore, the kit of the present invention can perform the delivery work hygienically when delivering the fluid in the container, and does not require complicated preparation for the delivery work.

  Hereinafter, other embodiments of the kit of the present invention will be described.

  FIG. 9 is a cross-sectional view showing another example of a stopper mechanism in the kit of the present invention. 10 is a cross-sectional view taken along line AA of FIG. 7 as viewed from the lower side of FIG.

  In the example shown in FIGS. 9 and 10, a substantially rectangular parallelepiped protrusion 21 f is formed in the thread groove at the opening end (downward in the drawing) of the inner peripheral surface of the first housing member 21. A convex portion 15 h having a slope and a vertical surface is formed on the lowermost thread of the cap 15.

  The first housing member 21 is made of a relatively flexible material such as a soft resin. The first cap 15 is made of a relatively hard material such as a stronger resin. Therefore, when the kit of the present invention is assembled, the engagement between the first housing member 21 and the first cap 15 proceeds, and when the inclined surface of the convex portion 15h comes into contact with the protrusion 21f, the inclined surface pushes up the protrusion 21f. One housing member 21 is slightly deformed outward to allow the convex portion 15h to pass over the projection 21f. On the other hand, when the convex portion 15h passes through the projection 21f, the projection 21f returns inward along the vertical surface of the convex portion 15h, resulting in the state shown in FIG. In the state shown in FIG. 10, the projection 21 f serves as a stopper, and prevents the first housing member 21 from rotating in the right direction. Therefore, the rotation direction of the first housing member 21 is limited, and the rotation of the first housing member 21 in the direction in which the first housing member 21 is detached from the first cap 15 is prevented.

  When the kit of the present invention shown in FIGS. 9 and 10 is used, the first housing member 21 or the first cap 15 is further rotated so that the first hollow needle 22 and the first seal member 14 are moved. The first seal member 14 is pierced by the tip of the first hollow needle 22.

  FIG. 11 is a schematic perspective view showing still another example of the stopper mechanism in the kit of the present invention.

  In the embodiment shown in FIG. 11, no screw thread and screw groove are provided on the inner peripheral surface of the first housing member 21, and instead, a substantially rectangular parallelepiped protrusion 21 g is formed. Further, the thread and the thread groove are not formed on the outer peripheral surface of the first cap 15, and a T-shaped groove 15i is formed instead.

  When the first housing member 21 and the first cap 15 are engaged, the protrusion 21g is fitted into the T-shaped groove 15i from the upper side to the lower side, and, for example, the first housing member 21 is attached to the first housing member 21. Press down in the direction of the cap 15. Further, the first housing member 21 or the first cap 15 is rotated so that the protrusion 21g is moved laterally from the branch point of the T-shaped groove 15i. Thereby, the fluctuation | variation of the relative position of the perpendicular direction of the 1st housing member 21 and the 1st cap 15 is blocked | prevented, and the 1st housing member 21 and the 1st cap 15 engage. And the relative position of the 1st housing member 21 and the 1st cap 15 can be fixed by making the protrusion 21g contact the edge part of the horizontal groove | channel of the T-shaped groove 15j.

  When the kit of the present invention shown in FIG. 11 is used, the first housing member 21 or the first cap 15 is rotated in the reverse direction to move the projection 21g to the branch point of the T-shaped groove 15i again. For example, the first hollow member 22 and the first seal member 14 are brought close to each other by pushing down the first housing member 21 downward and moving the projection 21g downward along the T-shaped groove 15i. The first seal member 14 is pierced at the tip of the first hollow needle 22. And the relative position of the 1st housing member 21 and the 1st cap 15 can be fixed by making the protrusion 21g contact the lower end part of the vertical groove of the T-shaped groove 15j.

  12 to 18 are enlarged perspective views showing still other examples of the stopper mechanism in the kit of the present invention.

  In the embodiment shown in FIG. 12, a protrusion 15k having a convex section with a notch 15j is formed on the outer peripheral surface of the substantially cylindrical first cap 15 in the generatrix direction of the outer peripheral surface. A straight groove 151 is formed on one side of the protrusion 15k along the protrusion 15k, and a pull-in portion having a step 15m as an end of the straight groove 151 at the end of the straight groove 15l. 15n is formed. In FIG. 12, one ridge 15 k having a notch 15 j is shown, but it is preferable that a plurality of ridges 15 k be formed on the outer peripheral surface of the first cap 15.

  On the other hand, a substantially cylindrical rail 21h having a notch 21i and a rail portion 21j is formed at the end of the substantially cylindrical first housing member 21 so as to protrude from the end of the first housing member 21. The recess 21k of the rail 21h can accommodate the protrusion 15k. The rail portion 21j can pass through the notch 15j and can be fitted into the linear groove 151. Although one rail 21h is shown in FIG. 12, it is preferable that a plurality of rails 21h are formed at the end of the first housing member 21 in accordance with the number of protrusions 15k.

  In the embodiment shown in FIG. 12, the ridge 15k is relatively movable in the recess 21k of the rail 21h along the generatrix direction of the outer peripheral surface of the first housing member 21, and the rail 21h The rail portion 21j is relatively movable in the straight groove 15l along the generatrix direction of the outer peripheral surface of the first cap 15.

  When assembling the kit of the present invention having the stopper mechanism of the mode shown in FIG. 12, first, the first housing member 21 is moved to the first housing member 21 so that the first cap 15 is fitted into the first housing member 21. Move in the direction of the cap 15. Specifically, the first housing member 21 is pushed in the direction indicated by the arrow in FIG. 12, or the first cap 15 is pushed in the reverse direction. Thereby, the rail 21h of the first housing member 21 enters the outer peripheral surface of the first cap 15 along the generatrix direction of the outer peripheral surface.

  Next, when the rail 21h enters the position where the rail portion 21j faces the notch 15j, the first housing member 21 is rotated in the direction indicated by the arrow in FIG. The cap 15 is rotated. Thereby, the rail part 21j of the rail 21h passes the notch 15j.

  And after the rail part 21j passes the notch 15j, as shown in FIG. 14, the rail part 21j fits in the linear groove 15l, and, thereby, further rotation is restrict | limited. Therefore, the first housing member 21 and the first cap 15 are engaged. Further, the ridge 15k faces the recess 21k of the rail 21h.

  Finally, the first housing member 21 is moved by the step 15m in the direction indicated by the arrow in FIG. 15, and the rail portion 21j is drawn into the drawing portion 15n. Since the reverse rotation of the rail portion 21j is hindered by the step 15m, the rail portion 21j is completely fixed in the linear groove 15l. Thereby, the relative position of the first housing member 21 and the first cap 15 is fixed. A closed space is formed between the first housing member 21 and the first cap 15.

  When using the kit of this invention provided with the stopper mechanism of the aspect shown in FIG. 12, the 1st housing member 21 is moved to the direction of the arrow shown in FIG. Thereby, the rail part 21j moves in the linear groove 15l, and the protrusion 15k fits into the recessed part 21k. Thereby, the rotation of the first housing member 21 is inhibited, and the first housing member 21 further approaches the direction of the syringe 11. For convenience of illustration, the first hollow needle 22 inside is shown in FIG. 16 through the space between the first housing member 21 and the first cap 15. The closed space between the first housing member 21 and the first cap 15 is kept closed.

  Then, by further moving the first housing member 21 in the direction of the arrow in FIG. 17, the first hollow needle 22 pierces the first seal member (not shown).

  FIG. 18 shows a state where the first hollow needle 22 has pierced the first seal member 14. As a result, the first fluid in the syringe 11 can be delivered to the outside of the syringe 11 via the first hollow needle 22.

  The kit of the present invention may be provided with a stopper mechanism as shown in FIGS. 9, 10, 11, or 12 to 18 instead of that shown in FIGS. 4 to 8.

  FIG. 19 is a view (partially sectional view) showing the whole of another embodiment of the kit of the present invention, and shows a state before the kit is assembled.

  The kit of the present invention shown in FIG. 19 has the same configuration as that of the first container 1 in addition to the first container 1, the first delivery pipe 2, and the first housing member 21 shown in FIG. A second container 1 ′ containing a second fluid instead of the first fluid, a second delivery pipe 2 ′, and a three-way valve 3 are provided.

  The three-way valve 3 includes a first inflow port 3a, a second inflow port 3b, and an outflow port 3c, and the connection destination of the outflow port 3c is connected to the first inflow port 3a or the second inflow port by a valve not illustrated. It can be switched to one of the inflow ports 3b. As the three-way valve 3, for example, a general-purpose three-way cock can be used.

  In the aspect shown in FIG. 19, the first inlet 3a of the three-way valve 3 is connected to the other open end of the first delivery pipe 2, and the second inlet 3b is the second delivery pipe 2 ′. And is connected to the second housing member 21 '.

  The second housing member 21 ′ has the same configuration as the first housing member 21.

  That is, as shown in FIG. 20, a second hollow needle 22 ′ is attached to the second housing member 21 ′. The interior of the second hollow needle 22 'communicates with the interior of the second delivery tube 2'. In addition, the aspect of attachment of 2nd hollow needle 22 'to 2nd housing member 21' is not restricted to what is shown in FIG. 20, For example, the 2nd hollow needle 22 is passed through various adapters. 'Can be attached to the second housing member 21'. In the embodiment shown in FIG. 20, the second delivery pipe 2 ′ is directly connected to the second housing member 21 ′. However, the second delivery pipe 2 ′ is connected to the second housing member 21 ′ via various adapters. Tube 2 'may be connected.

  In the embodiment shown in FIG. 20, the second housing member 21 ′ has an internal space 21′a. A screw thread and a thread groove are formed on the inner peripheral surface of the second housing member 21 ′ constituting the internal space 21′a. The second hollow needle 22 ′ is present in the internal space 21′a of the second housing member 22 ′. The shape of the second housing member 22 ′ is not particularly limited as long as it has the internal space 21′a, and may be various forms such as a cylindrical shape, a spherical shape, a rectangular parallelepiped shape, a cubic shape, and a bag shape. it can.

  The tip of the second container 1 ′ has the same configuration as the tip of the first container 1.

  That is, as shown in FIG. 20, a second fluid discharge port 11 ′ a is formed at the tip of the syringe 11 ′ of the second container 1 ′. A seal member 14 'is attached, and the second seal member 14' seals the discharge port 11'a. The second seal member 14 ′ prevents the second fluid in the space 1′a of the syringe 11 ′ from flowing out from the discharge port 11′a when not in use. The form of attachment of the second seal member 14 'to the tip of the syringe 11' is not particularly limited, and various forms such as fitting and adhesion can be employed.

  A second cap 15 ′ is attached around the second seal member 14 ′, and the second cap 15 ′ surrounds the second seal member 14 ′. An opening is formed in the second cap 15 ′, and the second sealing member 14 ′, in particular, the portion sealing the discharge port 11′a of the second sealing member 14 ′ from the opening, Is exposed. Further, a screw thread and a screw groove are formed on the outer peripheral surface of the second cap 15 '. In the embodiment shown in FIG. 20, a gap is present between the second seal member 14 ′ and the second cap 15 ′, but the gap may not be present.

  The thread and the thread groove on the inner peripheral surface of the second housing member 21 'and the thread and the thread groove on the outer peripheral surface of the second seal member 14' can be engaged. In this manner, the thread and screw groove at the open end of the inner surface of the second housing member 21 ′ are engaged with the screw thread and screw groove at the top of the outer peripheral surface of the second cap 15 ′. In this way, the second housing member 21 ′ and the second cap 15 ′ engage with each other, so that the second housing member 21 ′ surrounds the discharge port 11′a and the second housing member 21 ′. The internal space 21′a becomes a closed space isolated from the outside, and isolates the second hollow needle 22 ′ and the discharge port 11′a of the syringe 11 ′ from the outside. That is, a closed space is formed around the discharge port 11′a. The closed space is preferably airtight. The closed space preferably maintains a closed state.

  A second hollow needle 22 ′ is present in the closed space, and a part of the second seal member 14 ′ (the portion sealing the discharge port 11′a) is closed. It is exposed to the space. However, the second hollow needle 22 'and the second seal member 14' are separated from each other in the closed space.

  By forming the closed space by the engagement of the second housing member 21 ′ and the second cap 15 ′, the connection between the second container 1 ′ and the second housing member 21 ′ is completed.

  Note that the second housing member 21 ′ and the second cap 15 ′ may include a first stopper mechanism and a second stopper mechanism as shown in FIGS. Since this is the same as that shown in FIGS.

  On the other hand, the second housing member 21 ′ and the second cap 15 ′ may be provided with stopper mechanisms as shown in FIGS. 9, 10, 11, or 12 to 18. These are the same as those shown in FIGS. 9 and 10, FIG. 11, or FIGS.

  On the other hand, in the aspect shown in FIG. 19, the first container 1 and the first delivery pipe 2 are also connected as described above. As a result, the first inlet 3a is connected to the first hollow needle (not shown) of the first housing member 21 via the first delivery pipe 2, and the first inlet 3a is connected to the first inlet 3a. This makes it possible to communicate with a discharge port (not shown).

  In this way, the parts constituting the kit of the present invention shown in FIG. 19 are assembled to form the kit of the present invention.

  By assembling the kit, the first container 1 and the first housing member 21 are integrated. Therefore, the kit of the present invention shown in FIG. 19 includes the first container 1, the first housing member 21, and the first delivery pipe 2. After the assembly, the discharge port 11a of the first container 1 is provided. It is possible to communicate with the opening end of the first delivery pipe 2 (however, the discharge port 11a is sealed by the first seal member 14, and the first hollow needle 22 and the first seal member 14 are separated from each other). ).

  Further, the second container 1 ′ and the second housing member 21 ′ are also integrated by assembling the kit. Therefore, the kit of the present invention shown in FIG. 19 includes the second container 1 ′, the second housing member 21 ′, and the second delivery pipe 2 ′. The discharge port 11′a can communicate with the open end of the second delivery pipe 2 ′ (however, the discharge port is sealed by the second seal member 14 ′, and the second hollow needle 22 ′ and the second hollow needle 22 ′ are connected). Seal member 14 'is spaced apart).

  When the kit of the present invention having the form shown in FIG. 19 is used after assembling, the first container 1 is rotated by rotating the first housing member 21 or the first cap 15 shown in FIG. The relative position between the hollow needle 22 and the first seal member 14 is changed, the first hollow needle 22 is brought close to the first seal member 14, the first cap 15 is opened through the opening 15 a, and the first The first seal member 14 is pierced at the tip of the hollow needle 22.

  By the piercing of the first seal member 14 by the first hollow needle 22, the tip of the first hollow needle 22 reaches the discharge part 11 a of the syringe 11, and the space 1 a in the syringe 11 is the first delivery pipe 2. Communicates with the interior of As a result, the first fluid in the space 1a can be delivered to the first delivery pipe 2 via the first hollow needle 22, and the plunger (not shown) in the syringe 11 is moved to move the first fluid. Fluid is delivered to the first delivery tube 2.

  In the kit of the present invention shown in FIG. 19, the first sealing member 14 is pierced by the first hollow needle 22 in a closed space (see 21a in FIG. 5). As a result, fine contaminants such as the like are not mixed into the first fluid. Thus, the kit of the present invention can provide hygienically delivery of the first fluid.

  On the other hand, for the second container 1 ′, the second housing member 21 ′ or the second cap 15 ′ shown in FIG. 20 is rotated, and the second hollow needle 22 ′ and the second seal member 14 ′ are rotated. The relative position is changed, the second hollow needle 22 ′ is brought close to the second seal member 14 ′, the second cap 15 ′ is passed through the opening of the second hollow needle 22 ′, and the second hollow needle 22 ′ is moved to the second end. The sealing member 14 'is pierced.

  By the piercing of the second seal member 14 ′ by the second hollow needle 22 ′, the tip of the second hollow needle 22 ′ reaches the discharge portion of the syringe 11 ′, and the space in the syringe 11 ′ is the second. It communicates with the inside of the delivery pipe 2 '. As a result, the second fluid in the space of the syringe 11 ′ can be sent to the second delivery pipe 2 ′ via the second hollow needle 22 ′, and the plunger in the syringe 11 ′ not shown is moved. As a result, the second fluid is delivered to the second delivery pipe 2 '.

  As described above, since the second sealing member 14 ′ is pierced by the second hollow needle 22 ′, it is performed in the closed space (see 21′a in FIG. 20). Fine contaminants are not mixed into the second fluid. Therefore, the kit of the present invention can provide hygienically delivery of the second fluid.

  The kit of the present invention shown in FIG. 19 includes the first container 1, the first housing member 21, the first delivery pipe 2, the second container 1 ′, and the second housing member 21 ′.

Therefore, the delivery work can be performed in a sanitary manner, and it is not necessary to perform the connection work at the time of use.

  Therefore, the kit of the present invention can perform the delivery work hygienically when delivering the fluid in the container, and does not require complicated preparation for the delivery work.

  Further, in the embodiment shown in FIG. 19, the first fluid and the second fluid reach the three-way valve 3 through the first delivery pipe 2 and the second delivery pipe 2 ′, respectively. By appropriately operating a valve (not shown), the fluid flowing out from the outlet 3c of the three-way valve 3 can be switched to either the first fluid or the second fluid. In the aspect shown in FIG. 19, since the outflow port 3c of the three-way valve 3 is connected to the outflow pipe 4, the fluid that flows out to the outflow pipe 4 by appropriately operating the valve of the three-way valve 3 is the first fluid or the first fluid. The fluid can be appropriately switched to two fluids.

  Thus, for example, when using a contrast medium as the first fluid and physiological saline as the second fluid, or when using physiological saline as the first fluid and contrast medium as the second fluid, The fluid flowing out from the outflow pipe 4 can be appropriately switched to the contrast medium or physiological saline, and eventually the fluid supplied to the patient / subject can be appropriately switched to the contrast medium or physiological saline. The first fluid and the second fluid are not limited to the contrast medium and physiological saline.

  FIG. 21 is a view (partially sectional view) showing the whole of still another embodiment of the kit of the present invention, and shows a state before the kit is assembled.

  The aspect shown in FIG. 21 differs from the aspect shown in FIG. 19 in that the second inlet 3b of the three-way valve 3 is directly connected to the second housing member 21 ′. In the embodiment shown in FIG. 21, as in the embodiment shown in FIG. 19, the first housing member 21 and the second housing member 21 ′ are attached to the first container 1 and the second container 1 ′, respectively. The assembly of the kit is complete.

  In the embodiment shown in FIG. 21, unlike the embodiment shown in FIG. 19, the second delivery pipe 2 ′ is not used, so that the second fluid can be delivered quickly, and the first delivery pipe 2 is used. And entanglement of the second delivery pipe 2 'can be avoided.

  In the embodiment shown in FIG. 21, the first container 1 and the second container 1 ′ contain the first fluid and the second fluid, respectively. However, the first container 1 and the second container 1 ′ include Each may include a second fluid and a first fluid. Therefore, for example, when a contrast medium is used as the first fluid and a physiological saline is used as the second fluid, the first container 1 and the second container 1 ′ contain the contrast medium and the physiological saline, respectively. Alternatively, the first container 1 and the second container 1 ′ may contain physiological saline and a contrast medium, respectively.

  FIG. 22 is a view (partially sectional view) showing the whole of still another embodiment of the kit of the present invention, and shows a state before the kit is assembled.

  The aspect shown in FIG. 22 is that the first inlet 3a of the three-way valve 3 is directly connected to the first housing member 21, and the second inlet 3b of the three-way valve 3 is the second housing member. It differs from the embodiment shown in FIG. 19 in that it is directly connected to 21 ′. In the embodiment shown in FIG. 22, as in the embodiment shown in FIG. 19, the first housing member 21 and the second housing member 21 ′ are attached to the first container 1 and the second container 1 ′, respectively. Completes the assembly of the kit.

  In the embodiment shown in FIG. 22, unlike the embodiment shown in FIG. 19, the first delivery pipe 2 and the second delivery pipe 2 ′ are not used, so that the first fluid and the second fluid are quickly delivered. And entanglement of the first delivery tube 2 and / or the second delivery tube 2 ′ can be avoided.

  In the embodiment shown in FIG. 22, the first container 1 and the second container 1 ′ contain the first fluid and the second fluid, respectively. However, the first container 1 and the second container 1 ′ include Each may include a second fluid and a first fluid. Therefore, for example, when a contrast medium is used as the first fluid and a physiological saline is used as the second fluid, the first container 1 and the second container 1 ′ contain the contrast medium and the physiological saline, respectively. Alternatively, the first container 1 and the second container 1 ′ may contain physiological saline and a contrast medium, respectively.

  The kit of the present invention is preferably sterilized as necessary after assembly. In particular, in the kit of the present invention, it is preferable that sterilization is performed on a conduit through which the first fluid or the second fluid can pass. The type of sterilization treatment is not particularly limited, but it is more preferable to perform gas sterilization using a sterilizing gas such as ethylene oxide gas.
