Description

  The present invention relates to a restraint device for restraining a treatment device body such as a dialysis treatment or an infusion solution on a treatment table on which a patient can sit or lie down.

  For example, a hemodialysis apparatus includes a blood circuit (arterial blood circuit and venous blood circuit) in which a dialyzer (blood purifier) is formed, and a treatment apparatus body that collects the dialysate while supplying the dialysate to the dialyzer. Mainly configured, the patient is punctured with a puncture needle attached to the tip of the blood circuit, and blood purification and dehydration are performed with a dialyzer while circulating the patient's blood extracorporeally in the blood circuit .

  Usually, the treatment device body is placed in the vicinity of a treatment table such as a bed on which the patient can sit or lie down, and the patient is punctured with a puncture needle of a blood circuit extending from the treatment device body, and the blood is removed from the body. It is designed to circulate. On the other hand, an infusion device is similarly configured to extend a flexible tube from a main body of a treatment device for administering a drug solution to a patient at a predetermined speed, and puncture a patient on a treatment table with a puncture needle at the tip thereof to treat the infusion. It is configured.

  However, when an earthquake occurs, the treatment device main body and the treatment table move independently from each other due to the shaking, and the separation distance between the patient sitting on the treatment table or lying on the treatment table and the treatment device main body changes, When the length of the extended flexible tube (blood circuit, infusion tube, etc.) is longer than the treatment device body, the puncture needle may be forcibly removed from the patient.

In particular, in the case where a caster or the like is formed in the lower part of the treatment apparatus main body, it is easy to move due to shaking caused by an earthquake, and the above-mentioned problem is likely to occur. For this reason, conventionally, a caster disposed in the lower part of the treatment apparatus main body is provided with a vibration detection means, and when the caster tries to roll due to a shake (vibration) caused by an earthquake, the operation of the treatment apparatus main body is stopped. What is made to be disclosed is disclosed in Patent Document 1, for example.
JP-A-11-206879

  However, in the above prior art, the movement of the treatment apparatus body can be stopped when the shake due to the earthquake is detected, but the independent movement between the treatment apparatus body and the treatment table due to the shake cannot be avoided, There was still a possibility that the puncture needle was forcibly removed. Therefore, when the puncture needle is pulled out, there is a problem that blood and medicine in the flexible tube are scattered around.

  In addition, it is conceivable that the treatment device main body and the treatment table are connected and restrained by a rigid body such as a stay, and the relative position thereof is not changed by the shaking of the earthquake. The forceps attached to the flexible tube may come off, and the dialyzer and the infusion bag attached to the treatment apparatus body may fall off.

  In order to prevent the puncture needle from coming out of the patient during treatment, the body of the treatment device moves away from the treatment table due to the length of the extended flexible tube (blood circuit, infusion tube, etc.). However, if the body is constrained by a rigid body, movement of the treatment device in the direction close to the treatment table is also restricted, and even if one of them moves due to shaking, both move simultaneously. There was also a problem of end.

  The present invention has been made in view of such circumstances, and even if there is a shake due to the occurrence of an earthquake, the separation distance between the treatment device main body and the treatment table is prevented from becoming larger than a predetermined value, and the puncture needle is removed from the patient. It is an object of the present invention to provide a restraint device that can surely prevent the device from forcibly coming off and suppress the shaking of the treatment table from being transmitted to the treatment device body.

  According to the first aspect of the present invention, a patient sits on a treatment apparatus main body in which a tube-like distribution means that allows a treatment liquid such as a medicine or blood to extend while the tip is punctured by a patient is extended. Or a restraint device for restraining a treatment table that can lie down, comprising a flexible member of a predetermined length, and restricting movement of the treatment device body in a direction in which a separation distance from the treatment table is increased, and The movement in the direction in which the separation distance becomes smaller is allowed.

  According to a second aspect of the present invention, in the restraint device according to the first aspect, a part connected to the treatment apparatus main body side and a part connected to the treatment table side are separated, and these parts can be connected or separated. It is characterized by comprising a simple connecting means.

  According to a third aspect of the present invention, in the restraint device according to the first or second aspect, the surface fastener that can be joined to the surface fastener adhered to the predetermined portion of the treatment table is connected to the treatment table side. It is formed.

  According to a fourth aspect of the present invention, in the restraint device according to any one of the first to third aspects, the length of the treatment apparatus main body moves in a direction in which the separation distance increases with respect to the treatment table. It has a detecting means capable of detecting the tension applied in the direction, and can stop the operation of the treatment apparatus main body when the detecting means detects a tension larger than a predetermined value.

  According to the first aspect of the present invention, even when there is a shake due to the occurrence of an earthquake, the puncture needle is forcibly removed from the patient by avoiding the separation distance between the treatment apparatus main body and the treatment table being larger than a predetermined distance. Can be reliably prevented, and the bending of the flexible member can suppress the shaking of the treatment table from being transmitted to the treatment apparatus body.

  According to the second aspect of the present invention, when the part connected to the treatment apparatus main body side and the part connected to the treatment table side are separated by the connecting means, the treatment apparatus main body and the treatment table are connected to each other when it is not during treatment. They can be moved independently of each other, which is convenient during cleaning or maintenance of the treatment apparatus main body.

  According to the invention of claim 3, since the surface fastener that can be joined to the surface fastener adhered to the predetermined part of the treatment table is formed at the part connected to the treatment table side, the restraint device can be easily connected to the treatment table. And the length of the restraining device can be adjusted. Here, the hook-and-loop fastener refers to a magic tape (registered trademark) composed of a pair of members having a key-like structure and a member having a loop-like structure that can be engaged therewith.

  According to the invention of claim 4, when the tension greater than or equal to the predetermined value is detected by the detection means, the operation of the treatment apparatus body can be stopped. For example, when an earthquake occurs, the treatment apparatus body moves away from the treatment table and moves to the restraint device. Even if an excessive tension is applied, since the operation of the treatment apparatus main body is stopped, adverse effects can be minimized.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The restraint device according to the present embodiment is for restraining the treatment apparatus main body on the treatment table, and the applied treatment apparatus main body is a treatment table on which a patient can sit or lie down as shown in FIG. It consists of a dialysis machine main body 2 arranged in the vicinity of the bed 1. The dialyzer body 2 (therapeutic device body) is mounted on a mounting table 3 having casters 3a, and a blood circuit 4 as a distribution means as shown in FIG. 2 is extended. It is a thing.

  The blood circuit 4 is for performing hemodialysis and water removal while circulating the patient's blood extracorporeally, and is mainly composed of an arterial blood circuit 4a and a venous blood circuit 4b made of a flexible tube. The dialyzer 5 is connected between the arterial blood circuit 4a and the venous blood circuit 4b. An arterial puncture needle a and a venous puncture needle b that can puncture a patient are attached to the tips of the arterial blood circuit 4a and the venous blood circuit 4b, respectively.

  Furthermore, a relatively soft and large-diameter flexible tube 4aa is connected in the middle of the arterial blood circuit 4a, and a blood pump 6 for squeezing the flexible tube 4aa is arranged in the dialyzer body 2. It is installed. When the blood pump 6 is driven while the patient is punctured with the arterial puncture needle a and the venous side puncture needle b, the patient's blood reaches the dialyzer 5 through the arterial blood circuit 4a. Blood purification is performed, and defoaming is performed in the drip chamber 7, and the blood returns to the patient's body through the venous blood circuit 4b.

  The dialyzer 5 is formed with a blood introduction port 5a, a blood outlet port 5b, a dialysate inlet port 5c, and a dialysate outlet port 5d in the casing. Among these, the blood inlet port 5a has an arterial blood circuit 4a. The base end of the venous blood circuit 4b is connected to the blood outlet port 5b. The dialysate introduction port 5c and the dialysate lead-out port 5d are connected to a dialysate introduction line L1 and a dialysate discharge line L2 extending from the dialyzer main body 2, respectively.

  A plurality of hollow fibers are accommodated in the dialyzer 5, the inside of the hollow fibers is used as a blood flow path, and the space between the outer peripheral surface of the hollow fibers and the inner peripheral surface of the housing portion is dialysate. It is considered as a flow path. A hollow fiber membrane is formed in the hollow fiber by forming a large number of minute holes (pores) penetrating the outer circumferential surface and the inner circumferential surface, and impurities in the blood are passed through the membrane in the dialysate. It is comprised so that it can permeate | transmit. In the dialyzer main body 2, a water removal pump (not shown) for removing water from the blood of the patient flowing in the dialyzer 5 is disposed.

  Here, in this embodiment, as shown in FIG. 1, when the restraining device 8 is connected between the dialyzer body 2 and the bed 1, the dialyzer body 2 is restrained by the bed 2. Yes. The restraining device 8 is made of a flexible member (specifically, a belt-like member) having a predetermined length, and as shown in FIG. 3, has a divided structure comprising a main body side portion 8a and a bed side portion 8b. These are connected by connecting means 11.

  A main body side connecting portion 9 made of an L-shaped metal fitting is formed at one end of the main body side portion 8a (the end opposite to the end where the connecting means 11 is formed), as shown in FIG. In addition, it is configured to be fixed to the side surface of the dialyzer body 2 by a bolt B. On the other hand, a hook-and-loop fastener (magic tape (registered trademark)) is formed over a predetermined dimension on one end side (the end opposite to the end where the connecting means 11 is formed) of the bed side portion 8b. The bed 1 can be connected.

  Specifically, as shown in FIGS. 5 and 6, a surface fastener f is adhered in advance to a predetermined portion of the frame 1 a constituting the bed 1, and the surface fastener 10 a of the restraining device 8 is joined to the surface fastener f. The one end of the restraining device 10 can be fixed to the bed 1 by being wound around. As a result, the restraint device 8 can be easily connected to the bed 1, and the length of the restraint device 8 can be adjusted by arbitrarily changing the joint portion of the hook and loop fastener 10a to the hook and loop fastener f.

  As described above, by fixing one end of the restraint device 8 to the dialyzer main body 2 and the other end to the bed 1, the distance from the dialyzer main body 2 to the bed 1 is increased due to shaking caused by an earthquake. Even if it tries to move to, the movement can be restricted by the tension of the restraining device 8. In addition, since the restraint device 8 is made of a flexible member, when the dialyzer main body 2 tries to move in a direction in which the separation distance is reduced with respect to the bed 1 due to shaking due to the occurrence of an earthquake, the movement is allowed. Become.

  Therefore, even if there is a shake due to the occurrence of an earthquake during dialysis treatment, the distance between the dialyzer body 2 and the bed 1 is prevented from becoming larger than a predetermined value, and the puncture needle (arterial puncture needle a and vein puncture is removed from the patient. The needle b) can be reliably prevented from coming off, and the deflection of the flexible member can prevent the shaking of the bed 1 from being transmitted to the dialyzer body 2.

  The connecting means 11 is capable of connecting or separating the main body side portion 8a and the bed side portion 8b. As shown in FIGS. 3 and 7, the operating portion 11a engages with the engaging portion 11b and moves to the main body side. While both the part 8a and the bed side part 8b can be connected, by pressing the operation part 11a in a direction close to each other, the engagement with the engaging part 11b can be released and both parts can be separated. It is configured. Thereby, when it is not at the time of treatment, the dialyzer body 2 and the bed 1 can be moved independently from each other, which is convenient at the time of cleaning, maintenance at the dialyzer body 2 side, and the like.

Next, a restraining device according to another embodiment of the present invention will be described.
The restraint device according to the present embodiment is for restraining the dialysis device body 2 as the treatment device body to the bed 1 as the treatment table (see FIG. 1), as in the previous embodiment, and is shown in FIG. Thus, the detection means 12 is attached to the main body side connection portion 9. In addition, the same code | symbol shall be attached | subjected to the component similar to previous embodiment, and the detailed description shall be abbreviate | omitted.

  The detecting means 12 can detect the tension applied in the length direction of the restraining device 8 when the dialyzer body 2 moves in the direction in which the separation distance increases with respect to the bed 1, as shown in FIG. The coil spring 13 and the proximity switch 15 are fixed to the side surface of the dialyzer body 2. The proximity switch 15 includes a detector 15a urged toward the side in contact with the main body side connection portion 9, and a switch 15b that detects the detector 15a and turns it on / off. The switch 15b is turned on / off. A signal can be transmitted to the dialyzer body 2 side.

  The coil spring 13 is attached in a compressible manner around a rod member 14 whose tip is fixed to the main body side connection portion 9 by a nut N, and tension is applied to the restraining device 8 so that the main body side connection portion 9 is the same. When it is pulled in the direction of the arrow in the figure and the pulling force becomes a predetermined value or more, it is compressed and the movement of the main body side connecting portion 9 in the direction of the arrow relative to the detecting means 12 can be allowed. With such movement of the main body side connecting portion 9, the detector 15a follows and the switch 15b is turned off.

  That is, if the compression force of the coil spring 13 is set to a predetermined value, the main body side connecting portion 9 can be moved away from the detecting means 12 when a tension higher than a predetermined value is applied to the restraining device 8. Thus, the proximity switch 15 is turned off, and it can be detected that the restraint device 8 is applied with a tension larger than a predetermined value on the dialyzer body 2 side. Further, when detection by the detection means 12 is performed, a predetermined warning (warning display on the screen, warning by sound, warning by emitting a warning light, etc.) is performed, and the operation of the dialyzer body 2 ( In the case of this embodiment, the dialysate 5 is introduced and withdrawn and the blood pump 6 is driven).

  Therefore, for example, when an earthquake occurs, the operation of the dialysis device main body 2 is stopped even if the dialysis device main body 2 moves away from the bed 1 and an excessive tension is applied to the restraint device 8. The dialysis treatment can be stopped before the puncture needle is forcibly removed from the patient due to excessive tension, such as shearing with excessive tension or the dialysis device body 2 falling over, and the adverse effects are minimized. It can be.

  According to the above-described embodiment, the bed 1 is relatively heavy (the patient's entire weight is applied when lying down) and is placed relatively stably on the floor surface. Since the dialyzer main body 2 is restrained by the bed 1, the dialyzer main body 2 moves due to the shaking at the time of the earthquake occurrence, and even if force is applied to the bed 1 side via the restraint device 8, it falls down. There is no fear, and the dialysis device body 2 can be reliably restrained.

  Although the present embodiment has been described above, the present invention is not limited thereto. For example, both ends of the restraint device 8 are firmly connected to both the dialyzer body 2 and the bed 1 by fixing means such as bolts. It may be. The restraining device 8 may have other shapes (for example, a Y-shape branched in the length direction) as long as it is made of a flexible member having a predetermined length, and is made of various materials having a predetermined strength. Can be used.

  Furthermore, in the restraint device 8 of this embodiment, the dialyzer body 2 used in dialysis treatment and the bed 1 on which the patient can sit or lie down are connected and restrained, but other treatment device bodies (for example, An infusion device main body used in infusion may be connected to another treatment table (not limited to a bed on which a futon or the like is laid if a patient can sit or lie down). However, the treatment apparatus body to be applied only needs to have a tube-like distribution means extending therethrough not only in blood but also in a treatment liquid such as a drug, while the tip is punctured by a patient. is there.

  Further, the restraining device 8 may be constituted by a single flexible member in addition to the two separated constructions, and the connecting means may be eliminated. Furthermore, the detection means for detecting a tension greater than a predetermined value applied to the restraining device 8 is not limited to the one in the present embodiment, but has another configuration (for example, a load meter that can measure the tension). Etc.). In this embodiment, a proximity switch that is turned off when a tension greater than a predetermined value is applied is used. However, the switch is turned on when a tension greater than a predetermined value is applied to stop the operation of the treatment apparatus body. May be.

  A restraint device that is made of a flexible member of a predetermined length and restricts movement of the treatment apparatus body in the direction in which the separation distance from the treatment table increases, and allows movement in the direction in which the separation distance decreases. The present invention can also be applied to ones having different appearance shapes or other functions added.
