Description

  The present invention relates to a docking unit used, for example, in a medical portable monitor system.

  In a medical field such as a hospital, it is necessary to collect, analyze, and display biometric information (for example, electrocardiogram, blood pressure, number of breaths, and pulse) of each patient as needed. In addition, since the patient is transferred to a hospital room, examination room, operating room, etc., it is necessary to collect biological information of the patient along with the movement of the patient. Therefore, a small medical portable monitor system (for example, see Patent Documents 1 and 2) including a portable display, a data storage device, an interface capable of communicating with various medical devices, and the like is widely used.

  By using such a portable monitor system, it is possible to record and display the biological information of the patient being transferred without interruption.

  Moreover, in the medical portable monitor system, each device constituting the system is configured to be dockable and removable, so that only necessary devices can be carried according to the situation.

Japanese National Patent Publication No. 8-504345 Japanese National Patent Publication No. 8-504531

  Here, instead of using a cable-type connector, a connector that is fixed to the apparatus main body (hereinafter referred to as a main body integrated connector) can be connected to the apparatus at the same time as the apparatuses are docked. By adopting, there are advantages that there is no need to carry a cable connector separately, and that it is possible to reduce the labor of connector connection. In particular, since the medical portable monitor system is often used in an emergency, such advantages are greatly utilized. That is, in the medical portable monitor system, it is desirable to use a body-integrated connector instead of a cable-type connector.

  In addition, when adopting a body-integrated connector, in order to prevent dust or dirt from entering the connector, to prevent damage to the connector by hitting the connector with any object, and to ensure electrical safety in medical equipment It is desirable to provide a shutter that covers the connector so that it can be opened and closed.

  The opening and closing of the shutter is preferably performed in conjunction with the docking operation. In performing this operation, a configuration is required in which the connector is inserted into the shutter after the shutter is reliably opened, and the shutter is closed after the connector is securely retracted from the shutter. If this is not done, the connector and the shutter may collide and the connector and / or the shutter may be damaged.

  In addition, the body-integrated connector is less susceptible to the user's sense of connector insertion / removal when the connector is inserted / removed due to the weight of the device as compared with a cable-type connector or the like. In particular, when the docking partner is a portable display for medical use, the weight is several kilograms, so it is difficult to feel the connector insertion / extraction. Also, when connecting in an emergency state, it is difficult to feel that feeling. Furthermore, the number of times that the portable display is docked and removed is enormous. Therefore, there is a concern that the connector is damaged.

  The present invention has been made in consideration of the above points, and provides a docking unit that can prevent connector damage with a simple configuration.

One aspect of the docking unit of the present invention is:
A connector;
A shutter that can be opened and closed between an open state that exposes the connector and a closed state that covers the connector;
A first member having an abutting portion with which a part of a docking partner abuts;
A second member having a guide portion with which the first member engages;
A link connecting the shutter and the second member;
A first elastic body suspended between a main body chassis and the first member;
A second elastic body suspended between the first member and the second member;
It comprises.

  ADVANTAGE OF THE INVENTION According to this invention, the docking unit which can prevent damage to a connector with simple structure is realizable.

A connector unit 110 and a lock unit 130 are provided on the upper surface of the base unit 100. The connector part 110 and the lock part 130 are engaged with a connector part 240 and a lock part 260 provided on the lower surface of the carrier 200 as shown in FIG. Incidentally, the connector part 110 of the base unit 100 is covered with shutters 111 and 112 whose connectors (not shown) can be freely opened and closed. These shutters 111 and 112 are used when the carrier 200 is docked with the base unit 100. The protrusions 241 and 242 provided on the lower surface of the carrier 200 are opened.

  The carrier 200 contains a battery. The carrier 200 supplies power to the input box 300 and the portable display 400 when docked with the input box 300 and the portable display 400. As shown in FIG. 5, the carrier 200 and the portable display 400 are docked by inserting an insertion portion 410 protruding from the back of the portable display 400 into an insertion port 210 formed in the carrier 200 from above the carrier 200. It is done by inserting. Docking of the carrier 200 and the input box 300 is performed by inserting the input box 300 from the side of the carrier 200 and sliding it.

  The carrier 200 is provided with a handle 201, and the user can carry the carrier 200 by holding the handle 201. Usually, the user carries the carrier 200 in accordance with the movement of the patient in a state where the input box 300 is docked on the carrier 200 (and in some cases, the portable display 400 is also docked), and the biological information of the patient is input to the input box 300. Record. Then, the carrier 200 is docked to the base unit 100 when charging becomes necessary or when it is used as a stationary type.

  The input box 300 has a plurality of terminals 301 and can be connected to various medical sensors such as an electrocardiogram electrode and a blood pressure measurement cuff via the terminals 301. The input box 300 has a storage unit and can store biological information such as an electrocardiogram, blood pressure, number of breaths, and pulse measured based on the sensing result input from the terminal 301.

  In the present embodiment, since the input box 300 is supplied with power from the carrier 200 when docked with the carrier 200, the patient's biological information can be stored in the input box 300 even when the patient is transferred. become. As a result, uninterrupted biological information can be recorded.

  In the portable display 400, the display unit 401 has a touch panel configuration. The portable display 400 is provided with an indicator 402 at the top, and the indicator 402 is lit when the patient's condition becomes dangerous based on the patient's biological information. Further, as shown in FIG. 5, a handle 403 is provided on the back surface of the portable display 400, and the user can carry the portable display 400 by holding the handle 403.

<Docking mechanism in carrier>
The carrier 200 according to the present embodiment is provided with a docking mechanism for docking the portable display 400.

  Here, docking of the carrier 200 and the portable display 400 is performed by inserting the insertion portion 410 (FIG. 5) projecting from the back of the portable display 400 into the insertion port 210 (FIG. 1) formed in the carrier 200. This is done by inserting from above 200 and sliding the portable display 400 from above to below. Actually, the carrier 200 is formed with an engaging groove 211 that is retracted laterally in the insertion port 210 in the vertical direction, and the insertion portion 410 of the portable display 400 has a protrusion protruding sideways. 411 is formed. Accordingly, by inserting the protrusion 411 into the engagement groove 211 from above, the portable display 400 can be slid in the vertical direction with movements other than the vertical direction being restricted.

  In addition, the insertion slot 210 of the carrier 200 is provided with a docking mechanism that responds to the movement of the portable display 400. 6, 7 and 8 are perspective views showing the configuration and operation of this docking mechanism. 6, 7, and 8 are perspective views of the docking mechanism as seen from the oblique direction on the back.

  A connector 220 is provided at the lowermost position of the insertion port 210. This connector 220 is connected to a connector (not shown) provided on the bottom surface of the insertion portion 410 of the portable display 400. In the vicinity of the connector 220, a shutter 221 that can be opened and closed in a closed state that covers the connector 220 and an open state that does not cover the connector 220 is provided. The shutter 221 is pivotally supported on the base body 230 of the carrier 200 so as to be rotatable about the rotation shaft 222.

  The shutter 221 is connected to the second member 224 via a link 223. The second member 224 has a lower end rotatably connected to one end of the link 223. Here, the other end of the link 223 serves as the rotating shaft 222 of the shutter 221 described above. Thus, when the one end side of the link 223 is moved in the vertical direction by the second member 224, the other end side of the link 223 is The shutter 221 opens and closes with the rotation about the rotation shaft 222.

  The second member 224 is formed with a long hole 225 as a guide portion, and the first member 226 is slidably attached to the long hole 225. A first coil spring 227 is suspended between the first member 226 and the base body 230. Further, a second coil spring 228 is suspended between the first member 226 and the second member 224. Here, the spring constant of the second coil spring 228 is larger than the spring constant of the first coil spring 227. Further, the first member 226 is provided with a protrusion 229 that penetrates the long hole 225. The protrusion 229 comes into contact with the protrusion 411 (FIG. 5) of the portable display 400 when the portable display 400 is inserted into the insertion port 210.

  Next, the operation of the locking device will be described.

  First, when the portable display 400 is not inserted into the carrier 200, the shutter 221 is in a closed state covering the connector 220 as shown in FIG. Thereby, when the portable display 400 is not docked, it is possible to prevent entry of dust or dust into the connector 220 and damage to the connector 220 caused by hitting the connector 220 with any object. Can be secured.

  When docking the portable display 400 on the carrier 200, the user holds the portable display 400, and inserts the insertion portion 410 (FIG. 5) of the portable display 400 into the insertion port 210 of the carrier 200 from above. Then, the protrusion 411 of the insertion part 410 abuts from above the protrusion 229 of the first member 226, and the first member 226 is pushed down as the portable display 400 is lowered. At this time, since the spring constant of the second coil spring 228 is set larger than the spring constant of the first coil spring 227, only the first coil spring 227 extends, and as a result, the second member 224 is connected to the first member 226. It is pushed down together. As the second member 224 is pushed down in this way, the shutter 221 connected to the second member 224 via the link 223 is rotated, and the shutter 221 is opened.

  Eventually, as shown in FIG. 7, when the shutter 221 is fully opened, one side surface of the shutter 221 abuts on the base body 230, whereby the rotation operation of the shutter 221 and the lowering operation of the second member 224 are stopped.

  When the portable display 400 is further pushed down by the user from the state of FIG. 7, as shown in FIG. 8, the first member 226 slides in the long hole 225 of the second member 224, and only the first member 226 is portable. The display 400 descends as the display 400 descends. As described above, the first member 226 is interlocked with the movement of the portable display 400 independently of the second member 224 when the portable display 400 is further moved in the docking direction after the shutter 221 is in a predetermined open state. However, the portable display 400 is urged in the direction in which the connector comes out until the connectors are connected.

  As described above, the shutter 221 is opened and closed so that both the first member 226 and the second member 224 are integrally interlocked, and the connector is connected by the first member 226 moving alone. By completely separating the mechanism for opening and closing and the mechanism for connecting the connectors, it is possible to reliably prevent the connector (not shown) of the portable display 400 from colliding with the shutter 221, and the connector (not shown) and Damage to the shutter 221 can be prevented. That is, the connector of the portable display 400 is made to enter the shutter 221 after the shutter 221 is reliably opened, and the shutter 221 is closed after the connector of the portable display 400 is reliably retracted from the shutter 221. Can do.

  Here, the portable display 400 may be lowered against the elastic force of the first coil spring 227 from the closed state of the shutter 221 shown in FIG. 6 to the open state of the shutter 221 shown in FIG. Therefore, the portable display 400 is lowered and the shutter 221 is opened only by a relatively small force by the user or by the own weight of the portable display 400. On the other hand, the portable display 400 is connected to the first coil spring 227 and the second coil spring 228 from when the shutter 221 shown in FIG. 7 is opened to when the connector 220 shown in FIG. 8 is connected. Since the user is lowered against the elastic force, the user lowers the portable display 400 with a larger force than that during the shutter opening operation.

  As described above, the configuration is such that a greater force is imposed on the user for the movement of the portable display 400 when the connector is connected than for the movement of the portable display 400 when the shutter is opened / closed. The impact on the can be reduced. In other words, in this embodiment, the shutter 221 can be opened and closed with a relatively small force, and the connector connection requires a greater force, so that the user can smoothly and damage the connector. Without this, the portable display 400 can be docked on the carrier 200.

  When the portable display 400 is lowered to a position where the connectors are connected to each other, the engaging claws 412 (FIG. 5) provided on the side surface of the insertion portion 410 of the portable display 400 can be inserted into the insertion opening of the carrier 200. By engaging with an engagement groove 212 formed on the side surface of 210, the upward movement of the portable display 400 is restricted (that is, locked). Here, as shown in FIG. 5, the engaging claw 412 is connected to an unlocking handle 404 provided inside the handle 403 of the portable display 400, and the unlocking handle 404 is pulled up by the user. In response to this, it retracts from the protruding state to the buried state. As a result, the upward lock of the portable display 400 is released.

  The operation of detaching the portable display 400 from the carrier 200 is the reverse of the above-described docking, and the docking mechanism is sequentially in the state of FIG. 8 → FIG. 7 → FIG. Here, when pulling out the connector, the user needs to pull up the portable display 400 with a force equal to or greater than the sum of the weight of the portable display 400 and the force for pulling out the connector. When the connector is pulled out, the portable display 400 is given a force biased upward by the first coil spring 227 and the second coil spring 228, so that the user can pull out the connector with a smaller force. Since the portable display 400 is only given an upward force by the first coil spring 227 after the connector is disconnected (that is, the force of the second coil spring 228 is not given), an unnecessarily large force is applied. It will not be lifted up. In addition, since the user only needs to pull up the portable display 400 with a substantially uniform force in the entire separation process from the position where the connector is pulled out to the position where the shutter 221 is closed, the portable display can be smoothly removed from the carrier 200. 400 can be removed.

  As described above, according to this embodiment, the first member 226 engages with the first member 226 having the contact portion (protrusion 229) with which a part of the docking partner (portable display 400) contacts. A first member suspended between a second member 224 having a guide portion (long hole 225), a link 223 connecting the shutter 221 and the second member 224, and the main body chassis (base 230) and the first member 226. A coil spring 227 and a second coil spring 228 suspended between the first member 226 and the second member 224 are provided.

  Accordingly, it is possible to reliably prevent the connector from colliding with the shutter 221 at the time of docking and removal, and damage to the connector and the shutter 221 can be prevented.

  In addition, when the connector is connected, the connector is urged in the direction to be removed by the first member 226, so even if it is difficult to feel the sense of connector insertion due to the weight of the portable display 400, the impact of the connectors on each other can be reduced. Can prevent damage more.

  In the above-described embodiment, the first coil spring 227 is suspended between the base body 230 and the first member 226, and the second coil spring 228 is suspended between the first member 226 and the second member 224. However, instead of the first coil spring 227 and the second coil spring 228, other elastic bodies such as rubber may be used. And if the elasticity modulus of a 2nd elastic body is made larger than the elasticity modulus of a 1st elastic body, the effect | action similar to embodiment can be acquired.

  In the above-described embodiment, the case where the docking unit according to the present invention is applied to the carrier 200 of the medical portable monitor system has been described. However, the docking unit according to the present invention includes a connector, an open state in which the connector is exposed, and a connector. It is widely applicable to a docking unit that has a shutter that is openable and closable between a closed state and a connector that connects and disconnects a connector by opening and closing the shutter when docking and detaching.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The present invention can be applied to a carrier on which, for example, a medical portable display is docked.
