Description

  The present invention relates to a docking system in, for example, 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.

  Here, in the medical portable monitor system, various forms can be considered as to which unit (unit) the system is divided into and how each device is docked.

  In many of these forms, instead of using a cable-type connector, a connector fixed to the device body (hereinafter referred to as a body-integrated connector) is used to connect the connectors at the same time as the devices are docked. Adopting a configuration that can be performed has the advantage that it is not necessary 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.

  Furthermore, when adopting a body-integrated connector, it is possible to prevent entry of dust or dirt into the connector, to prevent damage to the connector by hitting an object against the connector, and to ensure electrical safety in medical equipment. Therefore, it is desirable to provide a shutter that covers the connector so that it can be opened and closed.

  By the way, when the main body integrated connector is adopted, it is necessary to dock the devices while aligning the connectors. This operation is complicated and time-consuming for users who are unfamiliar with the docking operation. It becomes. In particular, if the portion to be docked is arranged at a location that cannot be seen by the user during docking, such as the lower surface of the docking unit, there is a high possibility that more time will be spent. In particular, in the case of a portable medical monitor system, since it is often used in an emergency situation, the time required for docking should be short.

  The present invention has been made in view of the above points, and provides a docking system capable of quickly and easily performing docking including connector connection.

One aspect of the docking system of the present invention is:
A base unit provided with a connector and a shutter covering the connector on one surface;
A docking unit that is docked with the base unit and provided with a connector that is inserted into the connector of the base unit on the opposite surface that faces the one surface when docked;
A docking system comprising:
A plurality of protrusions disposed in an area different from the shutter on the one surface of the base unit;
A plurality of fitting holes disposed on the facing surface of the docking unit and fitted into the plurality of protrusions;
Comprising
The plurality of protrusions and the plurality of fitting holes are shaped so as to be fitted more easily as they are separated from the shutter.

  According to the present invention, the positioning of the protrusion and the fitting hole is performed step by step so that the protrusion and the fitting hole are sequentially guided away from the shutter, so that the docking including the connector connection can be performed quickly and easily. It becomes like this.

  The base unit 100 includes a power supply unit including an AC converter, a battery, various input / output terminals, and the like. 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.

<Mechanism for opening and closing the shutter of the base unit>
As shown in FIG. 1, the connector unit 110 is provided on the upper surface of the base unit 100. The connector unit 100 is covered with shutters 111 and 112 that can open and close a connector 113 (for example, FIG. 6B). In addition, as shown in FIG. 4, a connector portion 240 is provided on the lower surface of the carrier 200. The connector part 240 includes a connector 243 connected to the connector 113 of the base unit 100, and a first protrusion 241 and a second protrusion 242 for opening and closing the shutters 111 and 112.

  The first protrusions 241 are two chevron-shaped protrusions arranged with the connector 243 interposed therebetween. The second protrusions 242 are four triangular protrusions arranged with the connector 243 interposed therebetween. The first protrusion 241 is higher than the second protrusion 242.

  Further, both the first protrusion 241 and the second protrusion 242 have a height retracted above the lowermost surface of the carrier 200, that is, the placement surface 202 (that is, the inner side of the carrier 200). That is, when the carrier 200 is placed, the first and second protrusions 241 and 242 do not collide with the surface on which the carrier 200 is placed. In other words, this means that the heights of the first and second protrusions 241 and 242 are limited.

  When the user places the carrier 200 on the base unit 100, the carrier 200 is positioned and locked on the base unit 100 by the lock portions 130 and 260, and the shutters 111 and 112 are opened by the connector portions 110 and 240. Further, connectors 113 and 243 are connected. The configuration for positioning and locking by the lock portions 130 and 260 will be described in detail later.

  6, 7, 8, 9, and 10 are partial cross-sectional views illustrating the configuration of the first and second protrusions 241 and 242, the configuration of the first and second shutters 111 and 112, and the operation thereof. It is. 6 to 10 show the opening operation of the shutters 111 and 112 by the first protrusion 241 when the carrier 200 is placed on the base unit 100 (FIGS. 6A, 7A, 8A, 9A, and 10A). And the opening operation of the shutters 111 and 112 by the second protrusion 242 (FIGS. 6B, 7B, 8B, 9B, and 10B). 6A, FIG. 7A, FIG. 8A, FIG. 9A, and FIG. 10A cut the first protrusion 241 and the shutters 111 and 112 on the surface including the first protrusion 241 as shown by the one-dot chain line C1 in FIG. It is sectional drawing. 6B, FIG. 7B, FIG. 8B, FIG. 9B, and FIG. 10B show the second projection 242 and the shutters 111 and 112 on the surface including the second projection 242 as shown by the one-dot chain line C2 in FIG. It is sectional drawing cut.

  The first shutter 111 and the second shutter 112 constituting the shutter are rotatably supported by rotating shafts 111a and 112a in an opening direction indicated by an arrow in the drawing and a closing direction opposite to the opening direction. The rotating shafts 111a and 112a are provided with coil springs, and the first shutter 111 and the second shutter 112 are always urged in the closing direction opposite to the arrows by the coil springs. Incidentally, in the present embodiment, the first and second shutters 111 and 112 are connected by gears 111b and 112b, and thereby the opening and closing operations of each other are interlocked. Therefore, in the case of the present embodiment, only one of the first shutter 111 and the second shutter 112 may be energized without being energized by the spring.

  In addition, first protrusion abutting portions 244 into which the first protrusions 241 enter when the carrier 200 is docked are formed at the edges of both ends of the shutters 111 and 112. The first protrusion abutting portion 244 has a fan-like shape that is widened upward. Thereby, even when the shutters 111 and 112 are in the closed state, the tip of the first projection contact portion 244 is open, and the first projection contact portion 241 is in the opened state. The shutters 111 and 112 can be spread out in contact with the surface of 244. Even when the shutters 111 and 112 are in the closed state, the first protrusion abutting portion 244 is opened at least by an interval at which the first protrusion 241 can enter.

  First, the user holds the carrier 200 and approaches the base unit 100 from above. FIG. 6 shows a state before the first and second protrusions 241 and 242 reach the shutters 111 and 112. Further, when the carrier 200 is lowered, the state shown in FIG. 7 is obtained. As shown in FIG. 7A, the first protrusion contact portions 244 of the shutters 111 and 112 are in contact with the first protrusion 241. At this time, the second protrusion 242 has not yet reached the shutters 111 and 112, as shown in FIG. 7B.

  When the carrier 200 is further lowered from the state of FIG. 7, the state of FIG. 8 is obtained. As shown in FIG. 8A, the shutters 111 and 112 are spread by the first protrusion 241 when the contact portion at the tip of the first protrusion contact portion 244 slides along the inclined surface of the first protrusion 241. It is done. At this time, the second protrusion 242 has not yet reached the shutters 111 and 112 as shown in FIG. 8B.

  If the carrier 200 is further lowered from the state of FIG. 8, the state of FIG. 9 is obtained. As shown in FIG. 9A, the contact portions of the first protrusion contact portions 244 of the shutters 111 and 112 slide to a position beyond the slope of the first protrusion 241. At this time, as shown in FIG. 9B, the second protrusion 242 abuts against the opening end portions of the shutters 111 and 112. After this state, the shutters 111 and 112 are expanded by the second protrusions 242 as the second protrusions 242 are lowered.

  When the carrier 200 is further lowered from the state of FIG. 9, the state of FIG. 10 is obtained. As shown in FIG. 10B, the open end portions of the shutters 111 and 112 slide to the bottom surface of the carrier 200 beyond the slope of the second protrusion 242. In this way, the shutters 111 and 112 are expanded to a state where a connector can be connected.

  When the carrier 200 is further lowered from the state of FIG. 10, the connector 243 of the carrier 200 is connected to the connector 113 of the base unit 100.

  When the carrier 200 is detached from the base unit 100, the shutters 111 and 112 transition from the open state to the closed state in the order of FIGS. 10, 9, 8, 7, and 6.

<Mechanism for positioning and locking the carrier on the base unit>
Next, the configuration of the lock unit 130 provided on the upper surface of the base unit 100 and the configuration of the lock unit 260 provided on the lower surface of the carrier 200 will be described.

  As shown in FIG. 1, the lock part 130 of the base unit 100 has a plurality of protrusions 131a, 131b, 131c, and 131d. The plurality of protrusions 131 a, 131 b, 131 c, and 131 d are disposed on an area different from the shutters 111 and 112 on the base unit 100. That is, the plurality of protrusions 131 a, 131 b, 131 c, and 131 d are not disposed so as to surround the shutters 111 and 112 but are collectively disposed in an area adjacent to the shutters 111 and 112.

  A recess 133 is formed at a position surrounded by the plurality of protrusions 131a, 131b, 131c, and 131d. Engaging claws 132a, 132b, 132c, and 132d are provided in the recess 133. The engaging claws 132a, 132b, 132c, and 132d appear and disappear in conjunction with the operation of the slide lever 134 by the user. Specifically, when the user slides the slide lever 134 to the left in the figure, the engaging claws 132a, 132b, 132c, 132d are retracted.

  As shown in FIG. 4, a plurality of fitting holes 261 a, 261 b, 261 c, and 261 d into which the protrusions 131 a, 131 b, 131 c, and 131 d of the base unit 100 are fitted are formed in the lock portion 260 of the carrier 200. Further, the lock portion 260 is formed with a convex portion 263 that fits into the concave portion 133 of the base unit 100. Engaging grooves 262a, 262b, 262c, and 262d are formed in the convex portion 263. The convex portion 263 enters the concave portion 133, and the engaging claws 132a, 132b, and 262d are engaged with the engaging grooves 262a, 262b, 262c, and 262d. By engaging 132c and 132d, the carrier 200 is locked on the base unit 100.

  Here, as shown in FIG. 11, the heights of the shutters 111 and 112 and the plurality of protrusions 131a, 131b, 131c, and 131d are such that they all abut against the same plane (the chain line in the figure). . In short, the shutters 111 and 112 and the plurality of protrusions 131a, 131b, 131c, and 131d are all the same height. 11 is a schematic side view of the shutters 111 and 112 and the protrusions 131a, 131b, 131c, and 131d of the base unit 100 in FIG. 1 viewed from the front side of the base unit 100. In FIG. 11, the protrusions 131b and 131d are not shown hidden behind the protrusions 131b and 131d, but the protrusions 131b and 131d are also the same height as the protrusions 131b and 131d and the shutters 111 and 112.

  Thereby, when aligning the carrier 200 on the base unit 100, the lower surface of the convex portion 263 comes into uniform contact with the tops of the shutters 111 and 112 and the protrusions 131a, 131b, 131c, and 131d. The user can perform alignment while sliding the carrier 200 on the base unit 100.

  In addition, the interval m1 between the protrusion 131a and the protrusion 131c shown in FIG. 11 is shorter than the length of the short side of the convex portion 263 in FIG. Similarly, the interval between the protrusion 131b and the protrusion 131d is shorter than the length of the short side of the convex portion 263. In addition, the interval m2 between the protrusion 131a and the tops of the shutters 111 and 112 shown in FIG. 11 is shorter than the length of the short side of the convex portion 263. Similarly, the distance between the protrusion 131b and the tops of the shutters 111 and 112 is shorter than the length of the short side of the protrusion 263. Further, the interval between the protrusion 131 a and the protrusion 131 b and the interval between the protrusion 131 c and the protrusion 131 d are shorter than the length of the long side of the convex portion 263.

  Thereby, when the convex part 263 is shifted from the position where it fits into the concave part 133 in the left-right or front-rear direction, the convex part 263 is located between the protrusions 131a, 131b, 131c, 131d, or between the protrusions 131a, 131b and the shutter 111. , 112, and supported by any two or more apexes of the protrusions 131 a, 131 b, 131 c, 131 d or the shutters 111, 112, and can slide on the apexes.

  As described above, the height of the shutters 111 and 112 and the plurality of protrusions 131a, 131b, 131c, and 131d is the same height, and the interval between the protrusions 131a, 131b, 131c, and 131d and the shutters 111 and 112 is determined by the convex portion 263. By setting the interval so that the convex portion 263 does not enter between the concave portion 133 and the concave portion 133, the user can align the carrier 200 while sliding it flat on the base unit 100. Actually, as shown in FIG. 3, the upper surface of the base unit 100 and the lower surface of the carrier 200 are larger on the upper surface of the base unit 100 and the base unit 100 is not docked with the carrier 200. Since the carrier 200 may be docked to the unit 100, the user places the carrier 200 in the vicinity of the docking position on the base unit 100, and then searches the docking position while sliding the carrier 200 on the base unit 100. .

  Further, the plurality of protrusions 131a, 131b, 131c, and 131d and the plurality of fitting holes 261a, 261b, 261c, and 261d are shaped so as to be more easily fitted as they become farther from the shutters 111 and 112. As a result, as compared with a configuration in which all the protrusions and all the fitting holes cannot be positioned unless the positions of the fitting holes are completely coincident with each other, first, the protrusions 131c and 131d and the fitting holes 261c and 261d that are separated from the shutters 111 and 112 are firstly provided. Since the protrusions 131a and 131b and the fitting holes 261a and 261b in the vicinity of the shutter are positioned while being guided, the positioning can be performed more quickly and easily. Here, positioning is performed from a position away from the shutters 111 and 112. When positioning is performed from the direction of the shutters 111 and 112, the opening operation of the shutters 111 and 112 is started in a positioning state with coarse accuracy. In the worst case, the shutters 111 and 112 and the connectors 113 and 243 may be damaged. According to the configuration of the present embodiment, this can be effectively prevented.

  12 is a schematic cross-sectional view (FIG. 12A) in which the lower surface of the carrier 200 in FIG. 4 is cut by a plane including the fitting holes 261a and 261c, and a schematic line cut by a plane including the fitting holes 261b and 261d. FIG. 12B is a schematic sectional view (FIG. 12B). In the fitting holes 261c and 261d far from the shutters 111 and 112, an invitation surface 270 for inducing the protrusions 131c and 131d to the fitting holes 261c and 261d is formed. Accordingly, the protrusions 131c and 131d are easily fitted into the fitting holes 261c and 261d before the protrusions 131a and 131b.

  Incidentally, as can be seen from FIG. 12, in the case of the present embodiment, the farther away from the shutters 111 and 112, the larger the entrance of the fitting hole with respect to the tip of the projection, A shape that is easier to fit is realized as a distance from 112. Note that the tip of the protrusion is less likely to play in the fitting hole as it enters the depth of the fitting hole. That is, the positioning accuracy increases as the protrusion enters the back of the fitting hole.

  As described above, according to the present embodiment, the plurality of protrusions 131 a, 131 b, 131 c, 131 d disposed on an area different from the shutters 111, 112 on the one surface of the base unit 100, and the carrier 200 Are provided with fitting holes 261a, 261b, 261c, and 261d that fit into the plurality of projections 131a, 131b, 131c, and 131d, and the shutters are closer than the projections 131a and 131b and the fitting holes 261a and 261b closer to the shutters 111 and 112. The protrusions 131c and 131d and the fitting holes 261c and 261d far from 111 and 112 are shaped to be easily fitted. As a result, as compared with a configuration in which all the protrusions and all the fitting holes cannot be positioned unless the positions of the fitting holes are completely coincident with each other, first, the protrusions 131c and 131d and the fitting holes 261c and 261d that are separated from the shutters 111 and 112 are firstly provided. Since the protrusions 131a and 131b and the fitting holes 261a and 261b in the vicinity of the shutter are positioned while being guided, the positioning of the docking position of the carrier 200 on the base unit 100 can be performed more quickly and easily. Will be able to do.

  In addition, since the shutters 111 and 112 and the plurality of protrusions 131a, 131b, 131c, and 131d have heights that are all in contact with the same plane, when the carrier 200 is aligned on the base unit 100, the protrusions Since the lower surface of the H.263 is in uniform contact with the tops of the shutters 111 and 112 and the protrusions 131a, 131b, 131c, and 131d, the user can perform alignment while sliding the carrier 200 on the base unit 100. Become.

  Further, the interval between the plurality of protrusions 131a, 131b, 131c, and 131d is such that the protrusion 263 does not enter between the plurality of protrusions 131a, 131b, 131c, and 131d when the protrusion 263 is displaced from the recess 133. did. Accordingly, the user can more easily align the carrier 200 while sliding on the base unit 100.

  In the above-described embodiment, the case where the docking unit docked to the base unit 100 is the carrier 200 has been described, but the docking unit is not limited to this. Furthermore, in the above-described embodiment, the case where the docking system according to the present invention is applied to a medical portable monitor system has been described. However, the docking system according to the present invention includes a connector and a shutter covering the connector on one side. A docking system having a base unit provided and a docking unit docked to the base unit and provided with a connector to be inserted into the connector of the base unit on the opposite surface facing the one surface at the time of docking. Applicable.
