Background
The peritoneal dialysis method is as follows: dialysate is infused into the abdominal cavity to purify the blood using the peritoneum. When the dialysate is injected into the peritoneal membrane for a predetermined time, metabolites, salts, excess water and the like in the blood migrate to the dialysate side in the peritoneal cavity through the peritoneal membrane. The dialysate can be taken out of the body at a point of time when metabolites, moisture, and the like are sufficiently transferred to the dialysate, thereby enabling the blood to be purified.
As one of the peritoneal dialysis methods, there is Continuous Ambulatory Peritoneal Dialysis (CAPD) in which a dialysis solution is replaced several times within 1 day. In the continuous ambulatory peritoneal dialysis method, a protective cap is removed from a1 st connector provided at the tip of an adapter tube connected to a peritoneal catheter surgically implanted in a patient, a2 nd connector of the 1 st connector and a dialysis set (which is formed by connecting a dialysate bag, a drainage bag, and a2 nd connector to 3 ends of a Y-shaped infusion tube) is connected, and a dialysate is infused into the abdominal cavity via the tube. After injection, a new protective cap is aseptically mounted to the 1 st connector.
After the dialysate is retained in the abdominal cavity for a certain period of time, the cap is removed from the 1 st connector, the 1 st connector is connected to the 2 nd connector of a new dialysis set, and the solution in the abdominal cavity is drained to an empty drain bag. Subsequently, the flow path is switched, and new dialysate is injected into the abdominal cavity from the dialysate bag containing the new dialysate. Thereafter, the same operation as described above is repeated. Such a medical connector is disclosed in patent document 1 below, for example.

As shown in fig. 5, the 1 st mounting groove 48 provided in the rotating member 50 extends in the axial direction of the rotating member 50, and is open on the outer peripheral surface of the rotating member 50 and on both end surfaces in the axial direction of the rotating member 50. In a state where the 1 st connector 14 is mounted to the 1 st mounting groove 48, the leading end portion (the 1 st connector barrel 24) of the 1 st connector 14 protrudes from the 1 st mounting groove 48. Hereinafter, the opening of the 1 st mounting groove 48 on the side from which the 1 st connector 14 protrudes when the 1 st connector 14 is mounted is referred to as a "side opening 48s".
As shown in fig. 6, an engagement groove 48a into which one of the protrusions 22b of the 1 st connector 14 can be engaged (inserted) is provided at the bottom of the 1 st mounting groove 48. The cross-sectional shape of the engagement groove 48a is trapezoidal in accordance with the cross-sectional shape of the protrusion 22 b. A pair of elastic engagement pieces 48c that can elastically deform in the groove width direction of the 1 st mounting groove 48 are provided on the side walls 48b on both sides of the 1 st mounting groove 48. The pair of elastic engagement pieces 48c are disposed so as to face each other and can engage with the central body portion 22a of the 1 st connector 14. In a natural state, the distance between the pair of elastic engagement pieces 48c is slightly smaller than the outer diameter of the central body portion 22a of the 1 st connector 14.
In a state where the 1 st connector 14 is mounted in the 1 st mounting groove 48, the pair of elastic engagement pieces 48c are engaged with a position slightly higher than the center of the central body portion 22a, and the protrusion 22b is inserted into the engagement groove 48a. Therefore, the 1 st connector 14 is prevented from coming out of the 1 st mounting groove 48, and the 1 st connector 14 is prevented from rotating relative to the rotating member 50 about the horizontal axis.
As shown in fig. 2, the 2 nd holder 44 protrudes upward from the vicinity of the 2 nd end 40b (end on the arrow A2 direction side) of the base part 40. The 2 nd holder 44 has: a2 nd mounting groove 60 capable of horizontally holding the 2 nd connector 18; and a cover holding portion 62 capable of holding the protective cover 20.
Specifically, the 2 nd holder 44 is supported by the base portion 40 via the slide member 64. The 2 nd holder 44 is supported rotatably about a vertical axis by the slide member 64. The slide member 64 is provided to be slidable relative to the base portion 40 in a direction (a longitudinal direction of the base portion 40) toward and away from the 1 st holder 42. In the present embodiment, the slide member 64 has a slide projection 65 having a T-shaped cross section. The slide projection 65 is slidably inserted into a slide guide groove 66 having a T-shaped cross section provided in the base portion 40. The slide guide groove 66 extends along the longitudinal direction of the base portion 40.
The 2 nd mounting groove 60 extends in a horizontal direction. The 2 nd mounting groove 60 is opened at the upper surface 44a of the 2 nd holding member 44. Both ends of the 2 nd mounting groove 60 are opened at the outer circumferential surface 44b of the 2 nd holding member 44. In a state where the 2 nd connector 18 is mounted, the front end portion (the 2 nd connecting cylinder 32) of the 2 nd connector 18 protrudes from the 2 nd mounting groove 60. Hereinafter, the opening of the 2 nd mounting groove 60 on the side from which the 2 nd connector 18 protrudes when the 2 nd connector 18 is mounted is referred to as a "side opening 60s".
The side opening 60s of the 2 nd mounting groove 60 and the cover holding portion 62 are provided at different positions in the circumferential direction of the 2 nd holder 44. In the present embodiment, the cover holding portion 62 is provided in a direction different by 90 ° from the side opening 60s of the 2 nd mounting groove 60. The cover holding portion 62 may be provided in a range of less than 90 ° with respect to the side opening 60s of the 2 nd mounting groove 60.
The cap holder 62 has a hollow holding cylinder 63 projecting in the horizontal direction from the outer peripheral surface 44b of the 2 nd holder 44. A plurality of grooves 63a are provided at circumferentially spaced intervals on the inner circumferential surface of the holding cylinder 63. Each groove 63a extends along the axis of the holding cylinder 63. The protective cap 20 can be fitted to the holding cylinder 63. The plurality of ribs 20a of the protective cover 20 can engage with the plurality of groove portions 63a of the holding cylinder 63. In a state where the plurality of ribs 20a are engaged with the plurality of groove portions 63a, relative rotation of the protective cover 20 with respect to the cover holding portion 62 is prevented.
The 2 nd holder 44 can be switched to the 1 st position (fig. 2) where the cover holding portion 62 faces the side opening 48s of the 1 st mounting groove 48 and the 2 nd position (fig. 12) where the side opening 60s of the 2 nd mounting groove 60 faces the side opening 48s of the 1 st mounting groove 48. In the present embodiment, since the 2 nd holder 44 is rotatable about the vertical axis, the 2 nd holder 44 is rotated to switch between the 1 st position and the 2 nd position. The 2 nd retainer 44 is engaged with the slide member 64 so as to be rotatable with respect to the slide member 64 only in an angular range between the 1 st position and the 2 nd position (in the present embodiment, in a range of 90 °).
As shown in fig. 2, in a state where the 2 nd holding member 44 is switched to the 1 st position, the 1 st mounting groove 48 of the 1 st holding member 42 and the cover holding portion 62 of the 2 nd holding member 44 are aligned on the same straight line. As shown in fig. 12, in a state where the 2 nd holding member 44 is switched to the 2 nd position, the 1 st mounting groove 48 of the 1 st holding member 42 and the 2 nd mounting groove 60 of the 2 nd holding member 44 are aligned on the same straight line.
As shown in fig. 7, a pair of guide inclined surfaces 68 inclined such that the interval therebetween becomes narrower downward is provided at an upper portion of the 2 nd mounting groove 60. An engagement groove 60a into which one of the protrusions 30b of the 2 nd connector 18 can be engaged (inserted) is provided at the bottom of the 2 nd mounting groove 60. The cross-sectional shape of the engagement groove 60a is trapezoidal in accordance with the cross-sectional shape of the protrusion 30 b. A pair of elastic engagement pieces 60c that can elastically deform in the groove width direction of the 2 nd mounting groove 60 are provided on the side walls 60b on both sides of the 2 nd mounting groove 60. The pair of elastic engagement pieces 60c are disposed to face each other and can engage with the central body portion 30a of the 2 nd connector 18. In a natural state, the distance between the pair of elastic engagement pieces 60c is smaller than the outer diameter of the central body portion 30a of the 2 nd connector 18.
In a state where the 2 nd holder 44 is attached to the 2 nd attachment groove 60, the pair of elastic engagement pieces 60c are engaged with a position slightly higher than the center of the central body portion 30a, and the protrusion portion 30b is inserted into the engagement groove 60a. Therefore, the 2 nd connector 18 is restrained from coming out of the 2 nd mounting groove 60, while the relative rotation of the 2 nd connector 18 with respect to the 2 nd holder 44 centering on the horizontal axis is prevented.
Next, the operation of the medical connector attachment/detachment assisting apparatus 10 according to the present embodiment will be described.
Hereinafter, operations for attaching and detaching the 1 st connector 14 connected to the peritoneal catheter via the 1 st tube 12 (adapter tube) and the 2 nd connector 18 connected to the dialysate bag and the drainage bag (bag for containing body fluid or solution discharged from the abdominal cavity) via the 2 nd tube 16 will be described by taking a case where the continuous ambulatory peritoneal dialysis method is performed as an example. The 2 nd tube 16 is connected to the dialysate bag and the drain bag in common. Hereinafter, a member in which the 2 nd connector 18, the 2 nd tube 16, the dialysate bag, and the drainage bag are integrated is referred to as a "dialysis pack".
First, the operation of detaching the protective cover 20 from the 1 st connector 14 will be described.
As shown in fig. 8, the medical connector attachment/detachment assisting tool 10 is placed on a horizontal installation surface. As the base portion 40 is placed, the plurality of suction pads 46 provided on the bottom portion are attracted to the installation surface. Next, the 1 st connector 14 is mounted to the 1 st mounting groove 48 of the 1 st holder 42, and the 2 nd connector 18 is mounted to the 2 nd mounting groove 60 of the 2 nd holder 44. Thereby, the 1 st connector 14 and the 2 nd connector 18 are horizontally held by the 1 st holder 42 and the 2 nd holder 44, respectively.
In this case, the 1 st connector 14 is attached to the 1 st attachment groove 48 such that the 1 st connecting cylinder 24 (see also fig. 2) protrudes from the side opening 48s of the 1 st attachment groove 48. Further, the one protrusion 22b is inserted into the engagement groove 48a of the 1 st mounting groove 48, and the pair of elastic engagement pieces 48c are engaged with the central body portion 22a of the 1 st connector 14 (fig. 6). The 2 nd connector 18 is mounted to the 2 nd mounting groove 60 such that the 2 nd connecting cylinder 32 protrudes from the side opening 60s of the 2 nd mounting groove 60. Further, the one projection 30b is inserted into the engagement groove 60a of the 2 nd mounting groove 60, and the pair of elastic engagement pieces 60c are engaged with the central body portion 30a of the 2 nd connector 18 (fig. 7).
Then, the direction of the 2 nd retainer 44 is set so that the 1 st connector 14 and the cover holding portion 62 face each other (the 2 nd retainer 44 is set at the 1 st position). Thus, the protective cover 20 and the cover holding portion 62 attached to the 1 st connector 14 are arranged on the same line with a space therebetween (the protective cover 20 and the cover holding portion 62 are arranged coaxially). In this case, the 1 st mounting groove 48 is opened upward.
Next, as shown in fig. 9, the cover 28 is removed from the 2 nd connector 18, and the 2 nd holder 44 is horizontally slid toward the 1 st holder 42 side, so that the protective cover 20 is fitted to the cover holding portion 62.
Next, as shown in fig. 10, the rotating member 50 to which the 1 st connector 14 is attached is rotated in the arrow R1a direction while holding the operating lever 56. At this time, the rotary member 50 is rotated until the operating lever 56 abuts against the base portion 40. Thus, the 1 st connector 14 is rotated with respect to the protective cover 20 whose rotation is restricted by being held by the cover holding portion 62. With the rotation of the 1 st connector 14, the screw engagement between the external screw thread 14a of the 1 st connector 14 and the internal screw thread 20b of the protective cap 20 is released. In this manner, the operation of loosening the protective cover 20 is performed by rotating the rotating member 50 via the operating lever 56. Further, as the screw engagement of the protective cap 20 is released, the protective cap 20 is relatively displaced in the axial direction (arrow A2 direction) with respect to the 1 st connector 14 together with the 2 nd holding piece 44 by a little.
Next, as shown in fig. 11, when the 2 nd holder 44 is slid in a direction (arrow A2 direction) away from the 1 st holder 42, the protective cover 20 is detached from the 1 st connector 14.
The operation of connecting the 1 st connector 14 and the 2 nd connector 18 is performed as follows.
As shown in fig. 12, the 2 nd connector 18 attached to the 2 nd holder 44 is opposed to the 1 st connector 14 attached to the 1 st holder 42 by rotating the 2 nd holder 44 by 90 ° in the direction of the arrow R2 a. Thereby, the 1 st connector 14 and the 2 nd connector 18 are arranged on the same straight line with a space in the horizontal direction (the 1 st connector 14 and the 2 nd connector 18 are arranged coaxially).
Next, as shown in fig. 13, the 2 nd holder 44 is slid horizontally toward the 1 st holder 42 side, and the 1 st connector barrel 24 of the 1 st connector 14 is inserted into the 2 nd connector barrel 32 of the 2 nd connector 18. At this stage, the external threads 14a of the 1 st connector 14 and the internal threads 18a of the 2 nd connector 18 are not yet threadedly engaged.
Next, as shown in fig. 14, the rotating member 50 is rotated in the arrow R1b direction by the operating lever 56, whereby the 1 st connector 14 held by the rotating member 50 is rotated. At this time, the 1 st connector 14 rotates in the arrow R1b direction relative to the 2 nd connector 18 held by the 2 nd holder 44 in the rotation restricted state. Thereby, the male screw 14a of the 1 st connector 14 and the female screw 18a of the 2 nd connector 18 are screwed together. By rotating the rotating member 50 in the direction of the arrow R1b by the operating lever 56 in this manner, the 1 st connector 14 and the 2 nd connector 18 are screwed together. When the connection (screw coupling) of the 1 st connector 14 with the 2 nd connector 18 is completed, the 1 st mounting groove 48 faces upward. Further, with the screw engagement between the 1 st connector 14 and the 2 nd connector 18, the 2 nd connector 18 is displaced a little in the direction approaching the 1 st connector 14 together with the 2 nd retainer 44.
After the 1 st connector 14 and the 2 nd connector 18 are connected in this way, the 1 st connector 14 and the 2 nd connector 18 are respectively taken out upward from the 1 st holder 42 and the 2 nd holder 44. Then, the body fluid is discharged from the inside of the abdominal cavity of the patient to the drainage bag through the 1 st connector 14 and the 2 nd connector 18. Subsequently, the dialysis fluid is injected into the abdominal cavity of the patient via the 1 st connector 14 and the 2 nd connector 18. After the completion of the infusion of the dialysate, the connection between the 1 st connector 14 and the 2 nd connector 18 is released as follows.
As shown in fig. 15, the 1 st connector 14 and the 2 nd connector 18 connected to each other are attached to the medical connector attachment/detachment auxiliary device 10. Specifically, the 1 st retainer 42 and the 2 nd retainer 44 are brought into moderate proximity, and the 1 st connector 14 and the 2 nd connector 18 are mounted in the 1 st mounting groove 48 and the 2 nd mounting groove 60, respectively.
Further, the unshown package body in which the new protective cover 20 is placed is unsealed, the new protective cover 20 is taken out, and the new protective cover 20 is held by the cover holding portion 62. As shown by the phantom lines, a base member 70 is attached to the new protective cover 20. Therefore, the base member 70 is held by hand, and the new protective cover 20 is fitted to the cover holding portion 62 together with the base member 70. Next, the base member 70 is detached from the new protective cover 20 while maintaining the state in which the new protective cover 20 is held by the cover holding portion 62.
Next, as shown in fig. 16, the rotating member 50 is rotated in the arrow R1a direction by the operating lever 56, whereby the 1 st connector 14 held by the rotating member 50 is rotated. At this time, the 1 st connector 14 is relatively rotated with respect to the 2 nd connector 18 held in the 2 nd holder 44 in the rotation restricted state. Thereby, the screw engagement between the male screw 14a of the 1 st connector 14 and the female screw 18a of the 2 nd connector 18 is released.
By rotating the rotary member 50 in the direction of the arrow R1a by the operating lever 56 in this manner, the operation of releasing the screw engagement between the 1 st connector 14 and the 2 nd connector 18 is performed. Further, as the screw engagement between the 1 st connector 14 and the 2 nd connector 18 is released, the 2 nd connector 18 is displaced a little in the direction (arrow A2 direction) away from the 1 st connector 14 together with the 2 nd retainer 44.
Next, as shown in fig. 17, when the 2 nd holder 44 is slid in a direction (arrow A2 direction) away from the 1 st holder 42, the 1 st connector 14 and the 2 nd connector 18 are separated. After the 1 st connector 14 and the 2 nd connector 18 are separated, when the 2 nd holder 44 to which the 2 nd connector 18 is attached is rotated by 90 ° in the arrow R2b direction, the new protective cover 20 held by the cover holding portion 62 faces the 1 st connector 14 attached to the 1 st holder 42. That is, the new protective cover 20 and the 1 st connector 14 are arranged on the same line with a space in the horizontal direction.
Next, as shown in fig. 18, the 2 nd retainer 44 holding the new protector cap 20 is horizontally slid toward the 1 st retainer 42 side to which the 1 st connector 14 is attached, whereby the new protector cap 20 is fitted to the 1 st connector barrel 24 of the 1 st connector 14. At this stage, the 1 st connector 14 and the new protective cap 20 are not threadably engaged.
Next, as shown in fig. 19, the rotating member 50 is rotated in the arrow R1b direction by the operating lever 56, whereby the 1 st connector 14 held by the rotating member 50 is rotated. At this time, the 1 st connector 14 rotates in the direction of arrow R1b relative to the new protective cover 20 held in the cover holding portion 62 in the rotation restricted state. Thereby, the male screw 14a of the 1 st connector 14 is screwed with the female screw 20b of the new protective cap 20.
By rotating the rotating member 50 in the direction of the arrow R1b by the operating lever 56 in this manner, the operation of screwing the 1 st connector 14 and the new protective cover 20 is performed. When the connection (screw coupling) of the 1 st connector 14 with the new protective cover 20 is completed, the 1 st mounting groove 48 faces upward. Furthermore, with the screw engagement between the 1 st connector 14 and the new protective cap 20, the 2 nd holding member 44 holding the new protective cap 20 is displaced a little in a direction to approach the 1 st holding member 42.
After the new protective cap 20 is attached to the 1 st connector 14 in this manner, the 2 nd holding member 44 is moved in a direction away from the 1 st holding member 42. Thereby, the cover holding portion 62 is separated from the new protection cover 20. Then, the 1 st connector 14 with the new protective cover 20 attached is taken out upward from the 1 st retainer 42.
Next, after the dialysate is retained in the abdominal cavity of the patient for a certain period of time (for example, about 6 to 8 hours), the protective cap 20 is detached from the 1 st connector 14. Then, the 1 st connector 14 is connected to the 2 nd connector 18 of a new dialysis pack, and the solution in the abdominal cavity of the patient is drained into an empty drainage pack. Subsequently, new dialysate is injected into the abdominal cavity of the patient. Thereafter, the connection between the 1 st connector 14 and the 2 nd connector 18 is released and a new protective cover 20 is attached to the 1 st connector 14. At this time, the protective cover 20 is attached to and detached from the 1 st connector 14 and the 2 nd connector 18 are attached and detached as described above. In this way, the dialysate can be replaced several times within 1 day.
In this case, the medical connector attachment/detachment assisting tool 10 according to the present embodiment exhibits the following effects.
According to the medical connector attachment/detachment assisting tool 10, the 1 st connector 14 is horizontally attached to the 1 st holder 42, the cover holding portion 62 is horizontally moved toward the 1 st holder 42, and the rotating member 50 of the 1 st holder 42 is rotated, whereby the protective cover 20 can be easily detached from the 1 st connector 14 while the 1 st connector 14 is horizontally held. Further, by rotating the rotating member 50 of the 1 st holder 42 in a state where the protective cover 20 is held by the cover holding portion 62, the protective cover 20 can be easily attached to the 1 st connector 14 in a state where the 1 st connector 14 is held horizontally.
The 1 st connector 14 and the 2 nd connector 18 can be easily connected while the 1 st connector 14 and the 2 nd connector 18 are horizontally held by horizontally moving the 2 nd holder 44 to which the 2 nd connector 18 is attached toward the 1 st holder 42 to which the 1 st connector 14 is attached and rotating the rotating member 50 of the 1 st holder 42. In addition, in a state where the 1 st connector 14 and the 2 nd connector 18 are connected to each other, the 1 st connector 14 and the 2 nd connector 18 are attached to the 1 st holder 42 and the 2 nd holder 44, respectively, and the rotating member 50 of the 1 st holder 42 is rotated, whereby the connection between the 1 st connector 14 and the 2 nd connector 18 can be easily released.
By operating the 1 st holder 42 and the 2 nd holder 44 arranged on the base portion 40 in a predetermined order in this manner, the protective cover 20 can be easily attached to and detached from the 1 st connector 14 and the 2 nd connector 18 while the 1 st connector 14 and the 2 nd connector 18 are held horizontally (in a preferable state for preventing the entry of floating bacteria). Therefore, the medical connector can be safely and easily attached and detached even for an elderly patient.
The 2 nd holder 44 is rotatable about a vertical axis, and a side opening 60s of the 2 nd mounting groove 60 and a lid holding portion 62 are provided at different positions in the circumferential direction of the 2 nd holder 44. According to this configuration, the 2 nd holder 44 can be easily switched between the 1 st position and the 2 nd position only by rotating the 2 nd holder 44.
The cover holding portion 62 is provided in a direction different by 90 ° from the side opening 60s of the 2 nd mounting groove 60. With this configuration, the 2 nd holder 44 can be easily operated when the orientation thereof is changed between the 1 st position and the 2 nd position.
The 2 nd holder 44 is provided so as to be slidable relative to the base portion 40 in directions toward and away from the 1 st holder 42. With this configuration, the protective cover 20 and the 1 st connector 14 and the 2 nd connector 18 can be attached and detached without moving the 1 st connector 14 attached to the 1 st holder 42 in the axial direction.
The rotary member 50 is provided with a protruding operating lever 56. With this configuration, the user can easily rotate the 1 st connector 14 held by the rotating member 50 by gripping the operating lever 56.
When the connection of the 1 st connector 14 with the 2 nd connector 18 is completed, the 1 st mounting groove 48 faces upward (fig. 14). With this configuration, the 1 st connector 14 and the 2 nd connector 18 in the connected state can be easily detached from the medical connector attachment/detachment auxiliary tool 10.
A suction cup 46 is provided at the bottom of the base portion 40. According to this configuration, when the connector is attached and detached using the medical connector attachment and detachment assisting tool 10, the medical connector attachment and detachment assisting tool 10 is prevented from moving relative to the installation surface, and therefore, the attachment and detachment operation is further simplified.
In the above embodiment, the 2 nd holder 44 is configured to switch the 1 st position and the 2 nd position by rotating about the vertical axis, but the operation of switching the 2 nd holder 44 is not limited to the rotating operation. For example, the 2 nd holder 44 may be configured to be displaceable in a horizontal direction (in the direction of arrow B in fig. 1) orthogonal to the direction of separation of the 1 st holder 42 and the 2 nd holder 44, and the 2 nd mounting groove 60 and the cover holding portion 62 may be arranged in parallel in the direction of arrow B.
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
