Summary of the Invention

Problems to be Solved by the Invention

[0004] With the cap for medical devices of Patent Document 1, after connecting the cap for medical devices to the discharge part of the urinary catheter, even if the lid part of the connection plug main body part is opened, the urine bag plug cannot be directly connected, and it is necessary to connect the urine bag plug through a separate adapter. For this reason, an adapter is required every time the urine bag plug is connected, and both ends of the adapter after use are soiled with urine. From this, when reusing the adapter, disinfection is necessary, and as a result, it is troublesome for the user.

[0005] The present disclosure provides, for example, a cap for medical devices that can directly connect a urine bag plug and can ensure liquid tightness.

[0008] The following describes a medical device cap according to one embodiment of this disclosure. This disclosure discloses medical device caps of the first and second embodiments. Both embodiments of the medical device caps have a flexible tube, and the medical device cap can be closed by compressing the flexible tube. The medical device cap is connected to, for example, a urinary catheter.

[0009] <First Embodiment> A medical device cap according to the first embodiment will be described. Figure 1 is an explanatory diagram of the medical device cap in use. The medical device cap 1 is a medical device and is connected to the insertion part of a urinary catheter 2 having a lumen 2a, and a urine bag plug 3 is inserted into the medical device cap 1. The urine discharged from the urinary catheter 2 is configured to be discharged into a urine bag (not shown) through the tube 30 and urine bag plug 3 of the medical device cap 1, which will be described later. In the following description, the side of the medical device cap 1 that is on the urinary catheter 2 side in the X direction of Figure 1 will be referred to as the "tip" or "tip side", and the side of the medical device cap 1 that is on the urine bag plug 3 side in the X direction of Figure 1 will be referred to as the "base" or "base side". The X direction is parallel to the axial direction of the medical device cap 1. The Y direction is perpendicular to the X direction and is parallel to the direction of movement of the pressing member 40, which will be described later. The Z direction is perpendicular to the X and Y directions.

Fig. 4 is a side cross-sectional view of the medical device cap 1 of Fig. 1 in the open state of the lid member 20 but with the tube 30 in the open state. Fig. 5 is a cross-sectional view of the medical device cap 1 taken along the line V-V of Fig. 4. Fig. 6 is a side cross-sectional view of the medical device cap 1 of Fig. 1 with the tube 30 in the closed state. Fig. 7 is a cross-sectional view of the medical device cap 1 taken along the line VII-VII of Fig. 6. Figs. 4 and 6 are side cross-sectional views on a plane rotated 90° about the axis of the medical device cap 1 from the side cross-section of Fig. 2.

[0011] As shown in Figs. 1 - 3, the medical device cap 1 includes a cap body 10, a lid member 20, a tube 30, and a pressing member 40. The cap body 10 has a through-hole 10a penetrating along the X direction and is tubular, and has a connection portion 11, a pressing support portion 12, an intermediate portion 13, and a lid receiving portion 14. The connection portion 11 is circular-tubular and is tapered toward the tip. The connection portion 11 is connected to the urinary catheter 2. The pressing support portion 12 has an outer shape that is substantially rectangular parallelepiped-shaped and is provided at the base end of the connection portion 11. The pressing support portion 12 has a support hole 12a penetrating in the Y direction. As shown in Figs. 5 and 7, engagement protrusions 12B are provided inside the side wall of the pressing support portion 12. The pressing support portion 12 has a first pressing portion 12C that contacts the tube 30 on the side of the through-hole 10a.

[0012] As shown in Figs. 1 - 3, the intermediate portion 13 is circular-tubular and is provided at the base end of the pressing support portion 12. The lid receiving portion 14 is circular-tubular and is provided at the base end of the intermediate portion 13. The inner diameter of the lid receiving portion 14 is configured to be larger than the inner diameter of the intermediate portion 13, and a step portion 14A is formed by the intermediate portion 13 and the lid receiving portion 14. An annular first fitting rib 14B that protrudes toward the base end is provided on the step portion 14A. Locking protrusions 14C are provided on the outer peripheral surface of the lid receiving portion 14.

[0013] The lid member 20 has a hinge 21, a lid body 22, and a locking portion 23. The lid body 22 is connected to the lid receiving portion 14 via the hinge 21. On the inner surface side of the lid body 22, a convex portion 22A and a second fitting rib 22B are provided. The second fitting rib 22B forms an annular shape and is provided so as to surround the convex portion 22A. The locking portion 23 has a thin plate shape and is connected to the lid body 22 on the side opposite to the hinge 21, and an engagement hole 23a is formed therein.

[0014] The tube 30 is made of a flexible material and has a tip portion 31, a base end portion 32, and a flange portion 33. The tip portion 31 has a constant outer diameter and is fitted into the connection portion 11. The base end portion 32 has a tapered shape and is inserted into the pressing support portion 12, the intermediate portion 13, and the lid receiving portion 14 with a gap therebetween. Due to the presence of this gap, when the urine bag plug 3 is inserted into the base end portion 32, the urine bag plug 3 is inserted while expanding the base end portion 32. As a result, due to the contraction of the base end portion 32, the base end portion 32 can be brought into close contact with the urine bag plug 3, and urine leakage is suppressed. The flange portion 33 is provided on the base end side of the base end portion 32 and contacts the step portion 14A from the base end side. Urine or the like flows through the inner cavity 30a of the tube 30.

[0015] As shown in Figures 1 and 4-7, the pressing member 40 is inserted into the support hole 12a and is supported by the pressing support portion 12 so as to be movable along the Y direction. The pressing member 40 is a button-type pressing member and has an operating portion 41, a second pressing portion 42, and a pair of operating pieces 43. The operating portion 41 is the part pressed by the user and is located on one opening side of the support hole 12a, protruding outward from the pressing support portion 12 when the medical device cap 1 is in the open state. The second pressing portion 42 is provided on the inside of the operating portion 41, and its end is in contact with the tube 30. The second pressing portion 42 faces the first pressing portion 12C via the tube 30 in the Y direction. Each operating piece 43 extends from the Z-direction end of the operating portion 41 toward the other opening of the support hole 12a along the Y direction, with a gap between it and the second pressing portion 42. A first notch 43a and a second notch 43b are formed on the outer surface of each operating piece 43. The interlocking projection 12B of the pressing support portion 12 is configured to engage with the first notch 43a and the second notch 43b.

[0016] The opening and closing operation of the medical device cap 1 will now be described. As shown in Figure 5, when the lumen 30a of the tube 30 is not closed, the first notch 43a engages with the interlocking projection 12B, and the operating part 41 protrudes from the pressing support part 12. When the user presses the operating part 41, the pressing member 40 moves toward the tube 30. As shown in Figure 6, the tube 30 is squeezed between the first pressing part 12C and the second pressing part 42, crushing the tube 30, closing the lumen 30a, and the medical device cap 1 becomes closed. At this time, as shown in Figure 7, the second notch 43b engages with the interlocking projection 12B, so even if the pair of operating pieces 43 are pushed toward the tube 30, the pressing member 40 does not move, and the closed state of the lumen 30a is maintained. In this state, the ends of the pair of operating pieces 43 protrude outward from the pressing support part 12.

[0017] To return the medical device cap 1 from the closed state to the open state, the user pinches the pair of operating pieces 43 with their fingers, disengaging the second notch 43b from the interlocking projection 12B and pushing the pair of operating pieces 43 toward the operating section 41. This releases the compression of the tube 30 by the first retaining section 12C and the second retaining section 42, opening the lumen 30a and opening the medical device cap 1.

[0018] As shown in Figure 2, when closing the lid member 20, the second fitting rib 22B is fitted to the first fitting rib 14B so that its entire circumference is in close contact, and the protrusion 22A is pressed against the base end 32 of the tube 30 so as to crush the end of the base end 32 of the tube 30 and make it tightly contact. This closes the lumen 30a and the medical device cap 1 is in a closed state. The medical device cap 1 can also be closed by the lid member 20. When the lid member 20 is closed, the engagement hole 23a of the locking part 23 is locked to the locking projection 14C of the lid receiving part 14.

[0019] The medical device cap 1 is made of a flexible material and comprises a tube 30 attached to the cap body 10 and a pressing member 40 that presses against the tube 30. The pressing member 40 compresses the tube 30, closing its lumen 30a and causing the medical device cap 1 to close. The pressing member 40 is a button-shaped member that moves toward the tube 30 when subjected to external force, compressing the tube 30. In this way, since the tube 30, made of a flexible material, is attached to the cap body 10, a urine bag plug can be directly connected. Because the pressing member 40 compresses the tube 30 and closes its lumen 30a, the liquid-tightness of the medical device cap 1 can be ensured.

[0020] Next, a modified version of the medical device cap 1 of the first embodiment will be described. In the medical device cap 1 of the first embodiment, the cap body 10 was equipped with a pressing support portion 12 and a pressing member 40, but these may be omitted. For example, the lid member 20 may crush the tube 30 and close the lumen 30a of the tube 30, and the lid member 20 corresponds to the pressing member that closes the medical device cap 1. Even with such a configuration, the same effects as the medical device cap 1 of the first embodiment can be achieved.

[0021] <Second Embodiment> A medical device cap according to a second embodiment will now be described. Figure 8 is a perspective view of a medical device cap 101 according to the second embodiment. Figures 9 and 10 are side cross-sectional views of the medical device cap 101 in the open and closed states. The medical device cap 101 comprises a cap body 110, a tube 130, and an opening / closing member 140. The cap body 110 is cylindrical and has a through hole 110a that penetrates along the axial direction, and has, in order from the tip side, a connecting portion 111, a base fixing portion 112, and a tube fixing portion 114. The connecting portion 111 is tapered towards the tip. The base fixing portion 112 has an annular recess 112a formed on its outer circumference. The tube fixing portion 114 is provided with a fixing projection 114A on its outer circumference. The tube 130 is made of a flexible material and is fixed to the tube fixing portion 114 such that its tip rides over the fixing projection 114A.

[0022] The opening / closing member 140 includes a pair of bases 141, a pair of pressing pieces 142 corresponding to a pressing member, and a holding member 143. Each base 141 is semicircular in shape and has a semicircular connecting projection 141A on its inner circumferential surface. The pair of bases 141 are fixed to the base fixing part 112 by fitting the connecting projection 141A of each base 141 into the recess 112a and connecting each base 141 to each other. Each pressing piece 142 is substantially flat and is rotatably connected to the base end of each base 141. The pair of pressing pieces 142 are arranged symmetrically on either side of the axis of the tube 130. Each pressing piece 142 is pivotable around the base end of each base 141 so as to move closer to or away from the tube 130. The inner surface of each pressing piece 142 is provided with two pressing projections 142A extending in a direction perpendicular to the axial direction. As shown in Figure 10, the two pressing protrusions 142A of each pressing piece 142 are provided on each pressing piece 142 such that they are not in the same position in the axial direction when a pair of pressing pieces 142 are facing each other. The retaining member 143 is rotatably connected to the base end of one of the pressing pieces 142. The retaining member 143 is pivotable around the base end of one of the pressing pieces 142 so as to be closer to or further away from the base end of the tube 130. The retaining member 143 has a hook portion 143A at its free end.

[0023] The opening and closing operation of the medical device cap 101 will now be described. As shown in Figure 9, when the lumen 130a of the tube 130 is not closed, the pair of pressing pieces 142 are open and separated from the tube 130. The user pinches the pair of pressing pieces 142 with their fingers and rotates them so that they move closer together. As a result, as shown in Figure 10, the pair of pressing pieces 142 grip the tube 130, and the two pressing protrusions 142A of each pressing piece 142 crush the tube 130, closing the lumen 130a and closing the medical device cap 101. The two pressing protrusions 142A of each pressing piece 142 are interlocked and crush the tube 130.

[0024] The retaining member 143 is rotated to cover the base end of the tube 130, and the hook portion 143A hooks onto the hook projection 142B at the base end of the other pressing piece 142. This connects the base ends of the pair of pressing pieces 142. Because the elastic force of the tube 130 pushes each pressing piece 142 in an expanding direction, the hook of the hook portion 143A does not easily disengage from the hook projection 142B, and the closed state of the medical device cap 101 is maintained.

[0025] To return the medical device cap 101 from the closed state to the open state, the user pinches the pair of pressing pieces 142 with their fingers, slightly compressing the tube 130, while rotating the holding member 143 in the opening direction. This causes the pair of pressing pieces 142 to rotate away from the tube 130, releasing the compression of the tube 130 by the pair of pressing pieces 142, opening the lumen 130a, and opening the medical device cap 101.

[0026] The medical device cap 101 is made of a flexible material and comprises a tube 130 attached to the cap body 10 and a pair of pressing pieces 142 that press against the tube 130. The pair of pressing pieces 142 are provided symmetrically on either side of the axis of the tube 130, and each pressing piece 142 is rotatable around its end. By rotating the pair of pressing pieces 142 closer together, the tube 130 is clamped and the lumen 130a is closed. The pair of pressing pieces 142 crush the tube 130, ensuring the liquid-tightness of the medical device cap 101, while allowing the tube 130 attached to the cap body 110 to be directly connected to the urine bag plug.

[0027] The medical device cap 101 further includes a retaining member 143 that connects the ends of a pair of pressing pieces 142 that clamp the tube 130 and close the lumen 130a, thereby maintaining the closed state of the medical device cap 101.

[0028] Next, a medical device cap according to the first modification of the second embodiment will be described. The same reference numerals are used for the same components as in the medical device cap 101. Figure 11 is a perspective view of the medical device cap 201 according to the first modification of the second embodiment. Figures 12 and 13 are side cross-sectional views of the medical device cap 201 in the open and closed states. The medical device cap 201 comprises a cap body 110, a tube 130, an opening / closing member 240, and a sliding member 250.

[0029] The opening / closing member 240 has a pair of bases 141 and a pair of pressing pieces 242 corresponding to a pressing member. Each pressing piece 242 is substantially flat and rotatably connected to the base end of each base 141. The pair of pressing pieces 242 are provided symmetrically on either side of the axis of the tube 130. Each pressing piece 242 is pivotable around the base end of each base 141 to move closer to or away from the tube 130. Two pressing protrusions 242A extending in a direction perpendicular to the axial direction are provided on the inner surface of each pressing piece 242. As shown in Figure 13, the two pressing protrusions 242A of each pressing piece 242 are provided on each pressing piece 242 so that they are not in the same position in the axial direction when the pair of pressing pieces 242 face each other. A stopper 242B is provided at the base end of each pressing piece 242.

[0030] The sliding member 250 has an outer cylinder portion 251 and a frame portion 252. The outer cylinder portion 251 is tubular in shape and is provided to cover the outer circumference of a pair of base portions 141, and is slidably attached to the pair of base portions 141 along the axial direction of the tube 130. The frame portion 252 has a pair of frame connecting portions 252A and an annular frame end portion 252B. The pair of frame connecting portions 252A extend from the outer cylinder portion 251 toward the base end. The frame end portion 252B is connected to the ends of the pair of frame connecting portions 252A so as to surround the tube 130.

[0031] The opening and closing operation of the medical device cap 201 will now be described. As shown in Figure 12, when the lumen 130a of the tube 130 is not closed, the pair of pressing pieces 242 are open and separated from the tube 130. The user moves the slide member 250 toward the base end and uses the slide member 250 to press the pair of pressing pieces 242, causing them to rotate so that they are close to the tube 130. As a result, as shown in Figure 13, the two pressing protrusions 242A of each pressing piece 242 crush the tube 130, closing the lumen 130a and closing the medical device cap 201. The two pressing protrusions 242A of each pressing piece 242 crush the tube 130 while interlocking with each other. The slide member 250 stops when the base end of the outer cylinder portion 251 hits the stopper 242B. In this state, the frame end portion 252B is located on the outer circumference of the end of the tube 130. Since the outer cylinder portion 251 covers the pair of pressing pieces 242, the closed state of the medical device cap 101 is maintained.

[0032] When returning the medical device cap 201 from the closed state to the open state, the user moves the slide member 250 toward the tip. This causes the pair of pressing pieces 242 to rotate away from the tube 130, releasing the compression of the tube 130 by the pair of pressing pieces 242, opening the lumen 130a, and opening the medical device cap 201. As shown in Figure 13, in this modified example, the length of the tube 130 is configured to allow connection of the urine bag plug 3 and a urine bag (not shown) even when the medical device cap 201 is in the closed state. Therefore, the urine bag plug 3 and the urine bag (not shown) can be removed from the closed medical device cap 201, and the medical device cap 201 can be opened after connecting the urine bag plug 3 and the urine bag (not shown) to the closed medical device cap 201. This suppresses urine leakage when attaching and detaching the urine bag plug 3 and the urine bag (not shown).

[0033] The medical device cap 201 further comprises a sliding member 250 that is slidably mounted along the axial direction of the tube 130. By moving the sliding member 250, a pair of pressing pieces 242 rotate so as to move closer to each other, clamping the tube 130 and closing its lumen 130a. The pair of pressing pieces 242 crush the tube 130 and close its lumen 130a, thereby ensuring the liquid-tightness of the medical device cap 101.

[0034] Next, a medical device cap according to a second modification of the second embodiment will be described. The same reference numerals are used for the same components as those in the medical device caps 101 and 201. Figure 14 is a perspective view of the medical device cap 301 according to a second modification of the second embodiment. Figure 15 is an exploded perspective view of the medical device cap 301 of Figure 14. Figures 16 and 17 are side cross-sectional views of the medical device cap 301 in the open and closed states. The X direction is parallel to the axial direction of the medical device cap 301. The Y direction is perpendicular to the X direction and is parallel to the direction in which each of the pressing pieces 345, described later, extends. The Z direction is perpendicular to the X and Y directions and is parallel to the direction in which the pair of pressing pieces 345 face each other.

[0035] The medical device cap 301 comprises a cap body 110, a tube 130, an opening / closing member 340, a pair of pressing pieces 345 which are pressing members, and a sliding member 350. The opening / closing member 340 has a pair of bases 141 and a pair of support parts 342. Each support part 342 is provided at the base end of each base 141 and has a central support part 342A and a pair of end support parts 342B. Each end support part 342B is spaced apart in the Y direction from the central support part 342A. The central support part 342A and the pair of end support parts 342B form two openings 342c. A stopper 342D is provided at the base end of each support part 342.

[0036] Each pressing piece 345 is provided symmetrically across the axis of the tube 130 in the Z direction. Each pressing piece 345 is located inside each support portion 342, and the pressing on the tube 130 is supported by each support portion 342. Each pressing piece 345 is substantially flat and extends in the Y direction. The central support portion 342A contacts the central part of the pressing piece 345 from the outside, and the pair of end support portions 342B contact the ends of the pressing piece 345 from the outside. The Y-direction ends of each pressing piece 345 protrude outward from the opening 342c. The inner surface of the upper pressing piece 345 is provided with two pressing protrusions 242A extending in the Y direction, and the inner surface of the lower pressing piece 345 is provided with one pressing protrusion 242A extending in the Y direction. As shown in Figure 17, the pressing projections 242A of each pressing piece 242 are provided on each pressing piece 242 so that they are not in the same position in the axial direction.

[0037] As shown in Figures 14 and 15, the sliding member 350 has an outer cylinder portion 351 and a frame portion 252. The outer cylinder portion 351 is rectangular in shape and is provided to cover the outer circumference of the opening / closing member 340, and is slidably attached to the opening / closing member 340 along the X direction. Pressing protrusions 351A are provided on the inner surfaces of the four corners of the outer cylinder portion 351. An inclined surface 351B is formed at the base end of the pressing protrusion 351A.

[0038] The opening and closing operation of the medical device cap 301 will now be described. As shown in Figure 16, with the lumen 130a of the tube 130 not closed, the tube 130 is pressed by a pair of pressing pieces 345, and the lumen 130a is slightly narrowed. The user moves the slide member 350 toward the base end, and the inclined surfaces 351B of each pressing projection 351A come into contact with both ends of each pressing piece 345 in the Y direction, causing the pressing projections 351A to move each pressing piece 345 toward each other. As a result, as shown in Figure 17, the pressing projections 345A of each pressing piece 345 crush the tube 130, closing the lumen 130a and closing the medical device cap 301. The pressing projections 345A of each pressing piece 345 crush the tube 130 while interlocked with each other. The slide member 350 stops when the base end of the outer cylinder portion 351 hits the stopper 342D. In this state, the frame end 252B is located on the outer circumference of the end of the tube 130.

[0039] When returning the medical device cap 301 from the closed state to the open state, the user moves the slide member 350 toward the tip. This causes the pair of pressing pieces 345 to move away from each other due to the elastic force of the tube 130, releasing the compression of the tube 130 by the pair of pressing pieces 345, opening the lumen 130a, and opening the medical device cap 301. As shown in Figure 17, in this modified example as well, the length of the tube 130 is configured to allow connection of the urine bag plug 3 and a urine bag (not shown) even when the medical device cap 301 is in the closed state.

[0040] The medical device cap 301 further comprises a sliding member 350 that is slidably mounted along the axial direction of the tube 130, and a pressing member consisting of a pair of pressing pieces 345 symmetrically mounted on either side of the axis of the tube 130. By moving the sliding member 350, the pair of pressing pieces 345 move closer to each other, clamping the tube 130 and closing its lumen 130a. The pair of pressing pieces 345 crush the tube 130 and close its lumen 130a, thereby ensuring the liquid-tightness of the medical device cap 301.

[0041] This disclosure is not limited to the embodiments described above.
