Description

  The present invention relates to a hemostatic device, and a connector for a hemostatic device and a fluid supply device applied to the hemostatic device.

  Conventionally, as a method of introducing a catheter into a blood vessel, a method of first inserting a sheath introducer into the blood vessel and then introducing the catheter through the lumen of the sheath introducer is known. Such a sheath introducer is inserted into a blood vessel by being inserted into the blood vessel. Therefore, when pulling out the sheath introducer from the blood vessel, it is common to stop the site where the sheath introducer is inserted (the insertion site) using a hemostatic device.

  As this type of hemostatic device, for example, a band wound around the puncture site to be hemostatic, a balloon attached to the band, and an air supply pump for supplying air (fluid) to the balloon (For example, refer to Patent Document 1). According to such a hemostatic device, by inflating the balloon by supplying air to the balloon, it is possible to press the hemostatic target site with the expanded balloon and stop the hemostasis.

  In such a hemostatic device, one end of the air supply pipe is connected to the balloon, and a connector connectable to the air supply pump is connected to the other end of the air supply pipe. Here, the connection configuration between the connector and the air supply pump will be described. The connector incorporates a check valve to prevent the air in the balloon from flowing backward. The check valve is formed in a plate shape from an elastic material such as silicon rubber, and has a slit that can be opened and closed penetrating in the thickness direction. On the other hand, the air supply pump is composed of a syringe having a nozzle at the tip and a piston disposed in the syringe. Here, when the air supply pump is connected to the connector by inserting the nozzle of the syringe of the air supply pump into the slit of the check valve, the syringe and the air supply pipe are communicated. In this case, by pushing the piston into the syringe, the air inside the syringe is supplied to the balloon via the air supply pipe. On the other hand, when the air supply pump is removed from the connector by removing the syringe nozzle from the check valve slit, the check valve slit is closed and the syringe and the air supply pipe are disconnected. In this case, since the air in the balloon is prevented from leaking outside from the connector via the air supply pipe, the inflated state of the balloon is maintained.

Japanese Patent No. 4398747

  By the way, in the hemostatic device described above, various balloons having different internal capacities are prepared so that the degree of compression on the part to be hemostatic can be changed. For example, a relatively large size balloon is used in a hemostatic device used for hemostasis of the upper arm. In such a large balloon, when air is supplied to the balloon by the air supply pump, there is a case where the air cannot be filled into the balloon only by performing the air supply operation, that is, the piston pushing operation once. Therefore, the balloon is filled with air by performing the air supply operation a plurality of times.

  In such a case, it is necessary to refill the syringe with air after performing the air supply operation to the balloon once by the air supply pump. In this case, if the piston is pulled while the syringe nozzle is inserted into the check valve, the balloon air will flow backward. Remove the syringe (nozzle) from the connector, pull the piston, and refill the syringe with air. Will be. Then, the syringe is reconnected to the connector, and air is supplied (supplemented) to the balloon. However, such an operation of removing the syringe from the connector or reconnecting the connector to the connector may cause a delay in the treatment when hemostasis is required.

  In the above hemostatic device, after the balloon is filled with air, the syringe is removed from the connector to maintain the inflated state of the balloon. For this reason, when adjusting the degree of compression of the hemostasis target region by the balloon, for example, when increasing the degree of compression, it is necessary to reconnect the syringe to the connector, supply air to the balloon (supplement), and then remove the syringe from the connector again. there were. That is, when adjusting the degree of compression, troublesome work such as reconnecting and removing the syringe from the connector has occurred.

  The present invention has been made in view of the above circumstances, and has as its main object to provide a connector for a hemostatic device, a fluid supply device, and a hemostatic device capable of facilitating the work of replenishing fluid to the balloon. To do.

  In order to solve the above-described problem, the connector for a hemostasis device according to the first invention includes a fluid supply pump that discharges the fluid in the syringe by the movement of the piston accommodated in the syringe, and the balloon that expands by injecting the fluid. This is applied to a hemostasis device that supplies blood by a fluid supply pump through a conduit and presses the balloon in an inflated state against the target site to stop hemostasis, and connects the conduit and the syringe of the fluid supply pump. A connector for a hemostatic device provided at a connecting portion, wherein the connector is connected to the first body connected to the conduit, and to the syringe of the fluid supply pump, and is detachably assembled to the first body. A first passage is formed in the first body and communicated with the conduit, and the second body is communicated with the syringe. Two passages are formed, and in the assembled state of the two bodies, the relative position of the second body with respect to the first body is a communication position where the first passage and the second passage communicate with each other, and the first passage When the relative position is in the non-communication position, the fluid can flow into the second passage in the second body.

Is done. In this case, the fluid in the syringe can be supplied to the balloon via the conduit by the fluid supply pump. Further, when the relative position of the second body with respect to the first body is switched to the non-communication position, the first passage and the second passage are disconnected, and the conduit and the syringe are disconnected. In this non-communication state, fluid can flow into the syringe through the second passage. As a result, when the balloon is refilled with fluid, that is, when the fluid is injected into the balloon for the second time or later, the relative position of the second body with respect to the first body is not communicated with both bodies being assembled. The position can be switched to fill the syringe with fluid, and then the relative position can be switched to the communicating position to supply (replenish) the fluid in the syringe to the balloon. Therefore, it is not necessary to perform the troublesome work of removing or reconnecting the syringe from the connector when refilling the fluid to the balloon, and the work of refilling the balloon with fluid can be facilitated.

  According to a third aspect of the present invention, there is provided the connector for a hemostatic device according to the third aspect, wherein one of the two bodies is provided with a guide passage, and the other body is provided with a guided portion guided by the guide passage. The guide passage is a passage that displaces the relative position between the communication position and the non-communication position, and a passage end surface that defines one passage end of the guide passage is formed on the one body. It is formed as a side restricting portion, and a passage end surface defining the other passage end is formed as the non-communication position side restricting portion.

  According to the present invention, the displacement of the relative position of the second body with respect to the first body over the communication position and the displacement over the non-communication position are regulated by the passage end surfaces that define the passage ends on both sides of the guide passage. ing. In this case, the effect of the third aspect of the invention can be obtained while simplifying the configuration.

Is provided with a slit-shaped guide passage so as to penetrate in the thickness direction of the peripheral wall portion constituting the cylindrical portion, and the guided portion is provided on the outer peripheral portion of the other body. When the relative position is the non-communication position, the second passage is configured to communicate with the internal space in the cylindrical portion.

  According to the present invention, since the guide passage is provided in the peripheral wall portion of the cylindrical portion so as to penetrate in the thickness direction, the internal space in the cylindrical portion is connected to the connector outer region (for example, via the guide passage). Air). In such a configuration, when the relative position of the second body with respect to the first body is a non-communication position, the second passage communicates with the internal space in the cylindrical portion, and therefore the fluid with respect to the second passage in the second body. Inflow, that is, fluid inflow into the syringe is possible. In this case, the guide passage is also used as an inlet for guiding the fluid to the second passage, so that the multifunction of the guide passage is achieved.

  Further, the mouth portion 25a of the syringe 25 is connected to the connection portion 49 of the second body 22 (see FIG. 4). An internal thread portion of the mouth portion 25a of the syringe 25 is fastened to the male thread portion 49a of the connection portion 49, and the connection portion 49 and the mouth portion 25a are fixed by adhesion in the fastened state. Thereby, the syringe 25 is connected to the second body 22, and the second passage 50 and the syringe 25 are communicated with each other.

  Next, a method for using the hemostatic device 10 will be described. Here, it is assumed that hemostasis is performed with the puncture site as a hemostasis target in a state where the sheath introducer is pierced into the artery of the upper arm. Further, here, a description will be made mainly on the operation when supplying air to the balloon 13 to inflate the balloon 13.

  In the hemostasis operation, first, the belt body 11 is wound around the upper arm with the balloon 13 applied to the puncture site that is a hemostasis target site, and the belt body 11 is fixed by the surface fastener 14.

  Next, the air supply pump 24 is used to supply air to the balloon 13 and fill the balloon 13 with air. In the present embodiment, as described above, since the internal volume of the balloon 13 is larger than the internal volume of the syringe 25 of the air supply pump 24, air is supplied to the balloon 13 a plurality of times (here, twice). This fills the balloon 13 with air.

  Specifically, as the first air supply operation, the piston 26 of the air supply pump 24 is pulled in the syringe 25 while the relative position of the second body 22 with respect to the first body 21 in the connector 20 is set to the non-communication position. Is filled with a predetermined amount of air. For example, the syringe 25 is filled with 35 cm 3 of air. Thereafter, the relative position of the second body 22 with respect to the first body 21 is switched from the non-communication position to the communication position. Thereby, the nozzle part 48 of the 2nd body 22 is penetrated by the valve port 39 of the valve member 30, and the 1st channel | path 40 of the 1st body 21 and the 2nd channel | path 50 of the 2nd body 22 are connected. And in this communication state, the air in the syringe 25 is supplied to the balloon 13 by pushing the piston 26 into the syringe 25.

  Subsequently, as a second air supply operation, the relative position of the second body 22 with respect to the first body 21 is switched again from the communication state to the non-communication state, and a predetermined amount of air, for example, 35 cm 3 of air is filled in the syringe 25. To do. Thereafter, the relative position of the second body 22 with respect to the first body 21 is switched again from the non-communication position to the communication position, and the piston 26 is pushed in to supply (supplement) the air in the syringe 25 to the balloon 13. Thus, the balloon 13 is filled with a predetermined amount (70 cm 3) of air by a total of two air supply operations, and the balloon 13 is in a predetermined inflated state. The inflated balloon 13 compresses the target site for hemostasis to stop the site.

  Thereafter, the relative position of the second body 22 with respect to the first body 21 is switched from the communication state to the non-communication state. Thereby, the valve port 39 of the valve member 30 is closed and the backflow of the air from the balloon 13 is prevented. Therefore, the inflated state of the balloon 13 is maintained, and hemostasis of the hemostasis target site is continuously performed.

  Until a predetermined time elapses after the hemostasis of the hemostasis target region is started, the hemostasis state in the hemostasis target region is confirmed, and the degree of compression by the balloon 13 is adjusted according to the hemostasis state. For example, when hemostasis is not sufficiently performed at the hemostasis target site, air is replenished to the balloon 13 to increase the degree of compression of the balloon 13 against the hemostasis target site. Specifically, the syringe 25 is filled with air in a state where the relative position of the second body 22 with respect to the first body 21 is set to the non-communication position, and then the relative position is switched to the communication position to change the air in the syringe 25. Refill the balloon 13. On the other hand, when the pressure on the hemostatic target region is too strong and the patient is in pain, the air in the balloon 13 is partially removed to reduce the degree of compression on the hemostatic target region. Specifically, the relative position of the second body 22 with respect to the first body 21 is switched to the communication position, and a part of the air in the balloon 13 is sucked into the syringe 25 by retracting the piston 26. After the adjustment of the degree of compression is completed, the relative position of the second body 22 with respect to the first body 21 is switched to the non-communication position.

  The second body 22 is removed from the first body 21 after a predetermined time has elapsed since the start of hemostasis. At the time of removal, first, the second body 22 in the non-communication position is rotated around its axis, whereby the protrusion 37 is removed from the guide passage 53 and attached to the attachment / detachment passage 54 (specifically, a portion extending in the radial direction). Then, the second body 22 is pulled to the opposite side of the first body 21 in the axial direction to bring the protrusion 37 out of the attachment / detachment passage 54 (specifically, a portion extending in the axial direction). Note that when the second body 22 is rotated, the second body 22 is rotated by holding the operation unit 47. Thereby, the air supply pump 24 is removed from the hemostatic device 10, and a series of work is completed.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  The first body 21 connected to the air supply pipe 16 and the second body 22 connected to the syringe 25 of the air supply pump 24 are provided, and these bodies 21 and 22 are assembled in a detachable manner. In this assembled state, the relative position of the second body 22 with respect to the first body 21 is defined as a communication position where the first passage 40 and the second passage 50 are communicated with each other, and the passages 40 and 50 are not communicated. When the relative position is in the non-communication position, the air can flow into the second passage 50. Thus, when the balloon 13 is refilled with air, that is, when the air is injected into the balloon 13 for the second time or later, the above relative position is switched to the non-communication position while both the bodies 21 and 22 are assembled. The syringe 25 can be filled with air, and then the relative position can be switched to the communication position to supply (replenish) the air in the syringe 25 to the balloon 13. In this case, it is not necessary to perform the troublesome work of removing and reconnecting the syringe 25 from the connector 20 when refilling the balloon 13 with air, so that the work of refilling the balloon 13 with air can be facilitated. .

  In addition, since the first body 21 and the second body 22 can be attached to and detached from each other, hemostasis can be performed while the first body 21 is connected to the air supply pipe 16 side and the second body 22 is connected to the syringe 25 side. A series of operations can be performed. This can be said to be an advantageous configuration in preventing the inconvenience of erroneously connecting the distal end portion of the syringe 25 to a medical instrument other than the hemostatic device, that is, erroneous connection of the distal end portion of the syringe 25 during the hemostasis operation. That is, the mouth portion 25a of the syringe 25 and the connection portion 49 of the second body 22 are in conformity with the standard as described above, but can be connected to medical devices other than the hemostatic device if the standard is met. Is possible. In this regard, if the syringe 25 is fixed to the connector 20 (second body 22) as described above, such erroneous connection can be reliably prevented.

  When the relative position of the second body 22 with respect to the first body 21 is set to the non-communication position, the release of the assembly of both the bodies 21 and 22 is restricted. Therefore, after the balloon 13 is filled with air, the connector 20 (first 2) The syringe 25 and the balloon 13 can be held out of communication while the syringe 25 is connected to the body 22). In this case, it can be said that this is a preferable configuration when the balloon 13 is refilled with air after a predetermined time has elapsed since the balloon 13 was filled with air.

  A guide passage 53 is formed in the second body 22, and a protrusion 37 that is guided by the guide passage 53 is provided in the first body 21. In the second body 22, the relative position of the second body 22 with respect to the first body 21 is not communicated by one of the passage end surfaces 56 a and 56 b defining the passage end portions on both sides of the guide passage 53. When the position is displaced from the communication position to the communication position, the displacement exceeding the communication position is regulated. Then, when the relative position is displaced from the communication position to the non-communication position, the displacement beyond the non-communication position is restricted by the other passage end face 56b. In this case, the operation of switching the relative position of the second body 22 with respect to the first body 21 between the communication position and the non-communication position can be suitably performed. Further, by using the passage end surfaces 56a and 56b of the guide passage 53 to restrict the displacement of the relative position, the above-described effects can be obtained while simplifying the configuration.

  In a state in which the first body 21 is accommodated in the cylindrical recess 44 of the second body 22, both bodies 21 and 22 are assembled to each other, and a slit-shaped guide passage that penetrates in the thickness direction in the peripheral wall portion 51 surrounding the cylindrical recess 44. 53 was provided. And when the relative position of the 2nd body 22 with respect to the 1st body 21 turns into a non-communication position, it was set as the structure which connects the 2nd channel | path 50 to the cylindrical recessed part 44. FIG. In such a configuration, the cylindrical recess 44 communicates with the outside of the connector 20 through the guide passage 53. And when the relative position of the 2nd body 22 with respect to the 1st body 21 exists in a non-communication position, since the 2nd channel | path 50 is connected to the cylindrical recessed part 44, inflow of the air with respect to the 2nd channel | path 50, ie, to the syringe 25, is carried out. Inflow of air becomes possible. In this case, the guide passage 53 can also be used as an introduction port (ventilation port) for guiding air to the second passage 50, so that the guide passage 53 can be multifunctional.

  The cylindrical portion 75 is formed in a cylindrical shape from a resin material, and the inner diameter thereof is substantially the same as the outer diameter of the connecting portion 74. The cylindrical portion 75 has the connecting portion 74 disposed on the inner side thereof, and a part thereof is bonded to the connecting portion 74 in a state where a part of the connecting portion 74 extends to the side opposite to the air supply pipe 16 in the axial direction. It is fixed by. A plurality of ribs 85 extending in the axial direction are provided on the outer peripheral surface of the peripheral wall portion 76 constituting the cylindrical portion 75. These ribs 85 are arranged at predetermined intervals in the circumferential direction of the peripheral wall portion 76, and are guides for guiding an engaging portion 98 (claw portion 99) of the second body 72 described later in the axial direction of the cylindrical portion 75. Have a role.

  A portion of the peripheral wall portion 76 that extends from the connection portion 74 (hereinafter referred to as an extension portion 76a) is formed with a pair of connecting portion passages 81 that respectively guide connecting portions 93 of the second body 72 described later. ing. Each of the connecting portion passages 81 has a slit shape along the outer peripheral surface of the peripheral wall portion 76 and penetrates the peripheral wall portion 76 in the thickness direction. Each of the connecting portion passages 81 has the same configuration, and is arranged at intervals of 180 ° in the direction around the axis of the cylindrical portion 75.

  The connecting portion passage 81 includes a first passage portion 82 and a second passage portion 83 extending continuously from the first passage portion 82 (see also FIG. 8). The first passage portion 82 is formed so as to extend from the intermediate position in the axial direction in the peripheral wall portion 76 toward the side opposite to the connection portion 74 (in other words, the second body 72 side), and is opened at the end on the same side. ing. Further, the end of the first passage portion 82 opposite to the second body 72 side is defined by the passage end surface 108. The second passage portion 83 is formed so as to extend along the circumferential direction of the peripheral wall portion 76 from the end portion of the first passage portion 82 on the connection portion 74 side (in other words, the side opposite to the second body 72).

  The second body 72 is formed of a resin material, and includes a main body portion 91 having a columnar shape and a cylindrical portion 92 having an inner diameter larger than the outer diameter of the main body portion 91. The main body portion 91 is arranged coaxially with the cylindrical portion 92 in a state where one end portion in the axial direction enters the inside of the cylindrical portion 92, and in the arrangement state, the main body portion 91 is connected to the cylindrical portion 92 via the connecting portion 93. It is connected. The connection part 93 is arrange | positioned in the duplication site | part of the main-body part 91 and the cylinder part 92 in an axial direction, and has connected the outer peripheral surface of the main-body part 91, and the inner peripheral surface of the cylinder part 92 (refer FIG. 6). The connecting portions 93 have a plate shape having a predetermined width (length in a direction orthogonal to the axial direction), and a pair of connecting portions 93 are provided around the axis of the main body 91 at intervals of 180 °. In this case, a region between the outer peripheral surface of the main body 91 and the inner peripheral surface of the cylindrical portion 92 and where the connecting portion 93 is not provided becomes an opening region 87 that communicates the internal space of the cylindrical portion 92 with the inside and outside. ing.

  A nozzle portion 101 is provided at the end of the main body portion 91 on the cylindrical portion 92 side (that is, the first body 71 side) in the axial direction so as to protrude toward the first body 71 side. Further, a second passage 102 is formed in the main body portion 91 so as to extend in the axial direction. A part of the second passage 102 is formed inside the nozzle portion 101, and one end thereof is opened at the tip of the nozzle portion 101. The other end of the second passage 102 is opened at the end of the main body 91 opposite to the first body 71 side.

  A connecting portion 104 for connecting the mouth portion 25a of the syringe 25 of the air supply pump 24 is provided at the end of the main body portion 91 opposite to the first body 71 side. In addition, an operation portion 105 is provided at a portion near the first body 71 so as to protrude from the outer peripheral surface of the main body portion 91.

  The cylinder portion 92 is provided with a pair of engaging portions 98. The engaging portions 98 are arranged at intervals of 180 ° in the direction around the axis of the cylindrical portion 92. Specifically, the peripheral wall 96 of the cylindrical portion 92 is formed with a slit 97 extending in the axial direction and opening in the same direction on the opposite side to the main body 91 (in other words, on the first body 71 side). An engaging portion 98 is formed so as to extend from the bottom of the slit 97 toward the first body 71 in the axial direction of the cylindrical portion 92. Part of the engaging portion 98 extends to the first body 71 side from the cylindrical portion 92. In this case, the engaging portion 98 can be bent in the radial direction of the cylindrical portion 92.

  The engaging portion 98 is provided with a claw portion 99 at its distal end so as to protrude toward the axial line side of the cylindrical portion 92. The claw portion 99 can be engaged with an end portion 75a of the cylindrical portion 75 of the first body 71 opposite to the second body 72 side in the axial direction. Here, the engaging portion 98 corresponds to the assembly release restricting means.

  Next, a connection configuration between the first body 71 and the second body 72 will be described.

  As shown in FIG. 7, the second body 72 is connected to the first body 71 in a state where the cylindrical portion 75 of the first body 71 is inserted inside the cylindrical portion 92. In such a connected state, the relative position of the second body 72 relative to the first body 71 is moved to the non-communication position by moving the second body 72 relative to the first body 71 in the axial direction (see FIG. 7A). And a communication position (see FIG. 7B).

  First, when the relative position is in the non-communication position, as shown in FIG. 7A, the nozzle portion 101 of the second body 72 is spaced from the valve member 30, and the nozzle portion 101 is The valve member 30 is not inserted. In this case, the first passage 79 of the first body 71 and the second passage 102 of the second body 72 are not in communication. Further, the second passage 102 communicates with the inner space of the cylindrical portion 92 of the second body 72, and as a result, communicates with the outside of the connector 70 through the opening region 87. Further, in such a non-communication state, the engaging portion 98 (claw portion 99) of the second body 72 is engaged with the end portion 75 a of the cylindrical portion 75 of the first body 71. On the other hand, when the relative position is in the communication position, the nozzle portion 101 of the second body 72 is inserted into the valve member 30 as shown in FIG. The passage 102 is in communication.

Here, when the relative position is switched from the non-communication position to the communication position, the connection portion 93 of the first body 71 is guided along the connection portion passage 81 of the cylindrical portion 75 of the second body 72. . The guidance is shown in FIG. At the time of such switching, first, as shown in FIG. 8A, the connecting portion 93 enters the first passage portion 82 of the connecting portion passage 81 and is guided along the passage portion 82 to the passage end face 108 side. Thereafter, as shown in FIG. 8B, the connecting portion 93 reaches the end portion on the passage end surface 108 side of the passage portion 82, and comes into contact with the passage end surface 108. In this state, the relative position is a communication position. In this case, since the connecting portion 93 is in contact with the passage end face 108, the relative position is restricted from exceeding the communication position.

  In addition, when the second body 72 is rotated with respect to the first body 71 with the axis thereof as the rotation center at this communication position, the connecting portion 93 of the first body 71 is moved to the first position as shown in FIG. The second passage portion 83 is entered from the passage portion 82. In this state, the relative movement of the second body 72 in the axial direction with respect to the first body 71 is restricted, so that the relative position can be suitably held at the communication position.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  When the relative position of the second body 72 with respect to the first body 71 is in the non-communication position, the engagement portion 98 is engaged with the end portion 75a of the cylindrical portion 75 of the first body 71, whereby both the bodies 71, The assembly release of 72 is restricted. In addition, air can flow into the second passage 102 at this non-communication position. Therefore, as in the first embodiment, when air is replenished to the balloon 13, the syringe 25 is filled with air by setting the relative position to the non-communication position, and thereafter By setting the relative position as the communication position, the balloon 13 can be replenished with air. This eliminates the need for the troublesome work of removing or reconnecting the syringe 25 from the connector 20 when refilling the balloon 13 with air, thereby facilitating the work of refilling the balloon 13 with air. .

Other Embodiment
(1) In the first embodiment, the movement range of the protrusion 37 is regulated by the passage end surfaces 56a and 56b that define the passage end of the guide passage 53, but this may be changed. An example is shown in FIG. In the connector 110 shown in FIG. 9, an engagement portion 113 is provided so as to protrude from the distal end portion of the inner peripheral surface of the peripheral wall portion 114 in the second body 112. The engaging portion 113 is formed over the entire inner circumferential direction of the peripheral wall portion 114. The first body 21 is accommodated in the inner space 116 surrounded by the peripheral wall portion 114, and the first body 21 and the second body 112 are connected to each other in this accommodated state. In this state, the protrusion 37 of the first body 21 is disposed on the second body 112 (inner space 116) side of the engagement portion 113 in the axial direction of the body 21.

  In the connector 110 configured as described above, the relative position of the second body 122 with respect to the first body 21 is moved to the non-communication position by moving the second body 122 relative to the first body 21 in the axial direction (FIG. 9A). And a communication position (see FIG. 9B). And when the said relative position is made into a non-communication position, the projection part 37 of the 1st body 21 is engaged with the engaging part 113 of the 2nd body 122. FIG. On the other hand, when the relative position is at the communication position, the end surface 118 of the first body 21 on the second body 122 side contacts the bottom surface 112 a that defines the bottom of the inner space 116 in the body 122. In this case, the relative position of the second body 112 with respect to the first body 21 is restricted from being displaced beyond the communication position and from being displaced beyond the non-communication position. It can be done.

  Although not shown, the engagement portion 113 is provided with a pair of through-hole portions penetrating in the axial direction of the second body 122 in correspondence with the protrusions 37. When attaching / detaching the second body 122 to / from the first body 21, the attachment / detachment can be performed by passing the protrusions 37 of the first body 21 through the through-hole portions. In the above example, the engaging portion 113 corresponds to the non-communication position side restriction portion, and the bottom surface 112a corresponds to the communication position side restriction portion. Further, the engagement release 113 and the projection 37 constitute an assembly release restricting means.

  (2) In the first embodiment, the protrusion 37 is provided in the first body 21 and the guide passage 53 is formed in the second body 22, but this is changed and the protrusion is provided in the second body 22. A guide passage may be formed in the first body 21. An example is shown in FIG. In the connector 120 shown in FIG. 10, a cylindrical portion 124 is provided in the first body 121, and the accommodated portion 125 of the second body 122 is accommodated in the internal space 129 of the cylindrical portion 124. And in this accommodation state, the 1st body 121 and the 2nd body 122 are mutually connected. A guide passage 127 is formed in the cylindrical portion 124 of the first body 121 so as to penetrate the peripheral wall portion 128 constituting the cylindrical portion 124, and a protrusion is formed on the outer peripheral surface of the accommodated portion 125 of the second body 122. A portion 126 is provided. The protrusion 126 is guided along the guide passage 127 of the first body 121.

  In this configuration, as shown in FIG. 10A, when the relative position of the second body 122 with respect to the first body 121 is switched to the communication position, the projecting portion 126 defines each end surface 133 a of the guide passage 127. Abuts against one of the passage end surfaces 133b of 133b. Further, as shown in FIG. 10B, when the relative position is switched to the non-communication position, the protrusion 126 comes into contact with the other passage end surface 133a of the guide passage 127. Thereby, similarly to the said 1st Embodiment, the switching of the said relative position can be performed suitably. Further, when the relative position becomes a non-communication position, the second passage 131 of the second body 122 communicates with the internal space 129 of the cylindrical portion 124 of the first body 121. As a result, air can flow from the outside of the connector 120 to the second passage 131 and thus to the syringe 25 via the guide passage 127 and the internal space 129.

  (3) In the first embodiment, the guide passage 53 is formed in a slit shape in the peripheral wall portion 51 of the second body 22. However, the guide passage 53 is changed to a groove shape on the inner peripheral surface of the peripheral wall portion 51. You may form in. In this case, the protrusion 37 is guided along the groove-shaped guide passage 53. Further, the second body 22 may not be provided with the guide passage 53 (and the attachment / detachment passage 54). In this case, the protrusion 37 can be omitted in the first body 21. Even in this configuration, the relative position of the second body 22 with respect to the first body 21 can be switched between the communication position and the non-communication position. In each of the above-described configurations, it is necessary to separately provide the connector 20 with a ventilation passage that communicates the inside and outside of the cylindrical recess 44. For example, the ventilation passage forms a ventilation hole penetrating in the thickness direction in the peripheral wall portion 51 or a predetermined gap between the outer peripheral surface of the first body 21 and the inner peripheral surface of the second body 22 (peripheral wall portion 51). It is conceivable to configure by providing a.

  (4) In each of the above embodiments, the valve member 30 is used as the sealing member, but other sealing members may be used. For example, as shown in FIG. 11, a duckbill check valve 141 may be used as the sealing member. The check valve 141 has a slit-shaped valve port 141a. The valve port 141a is always closed based on the elastic force of the check valve 141. When the differential pressure before and after the check valve 141 becomes positive, that is, on the upstream side of the check valve 141. It opens when the pressure is greater than the pressure on the downstream side.

  In FIG. 11, the check valve 141 is provided in the middle of the second passage 50 in the first body 21 (main body portion 28), and the second passage 22 side of the check valve 141 in the second passage 50, specifically An annular seal member 142 made of silicon rubber is provided at the end of the two passages 50 on the second body 22 side. The seal member 142 is provided in a state where the outer peripheral surface thereof is in close contact with the inner peripheral surface of the second passage 50, and the inner diameter thereof is smaller than the outer diameter of the nozzle portion 48. In FIG. 11, only the nozzle portion 48 is shown for the second body 22 for convenience.

  In the above configuration, the relative position of the second body 22 with respect to the first body 21 is as shown in FIG. 11 (a), the second position shown in FIG. 11 (b), and FIG. 11 (c). Switching to the third position with the third position is possible. The configuration of the guide passage is different from that of the first embodiment so that the three positions can be switched. Specifically, as shown in FIGS. 11 (a-2) to (c-2), the guide passage 146 of the present example has an intermediate passage 150 extending in the radial direction in the middle thereof, and the intermediate passage 150 is The two guide passage portions 148 and 149 extending in the axial direction are connected to each other. The two guide passage portions 148 and 149 respectively extend from both ends of the intermediate passage 150 to the opposite side in the axial direction. Specifically, the first guide passage portion 148 extends to the opposite side to the first body 21. The second guide passage portion 149 extends to the first body 21 side.

  In the above configuration, as shown in FIG. 11A-1, when the relative position is at the first position, the nozzle portion 48 of the second body 22 is separated from the first body 21 in the axial direction. Therefore, the first passage 40 and the second passage 50 are not in communication.
