Definitions

  • the invention relates to a rack for holding a plurality of medical devices according to the preamble of claim 1.
  • a rack of this kind comprises a plurality of connection means for connecting the plurality of medial devices to the rack, a power supply unit for providing electric power to the plurality of medical devices and a communication means for providing a communication link for the medical devices.
  • the rack for example may be used for holding a number of infusion pumps for administering for example a fluid such as medication or nutrients to a patient.
  • the rack combines several infusion pumps to form a complex infusion system which in particular may be used in an intensive care unit in a hospital environment.
  • the rack in this context serves different functions: the rack shall organize the medical devices to optimize the required space to arrange the medical devices; the rack shall supply electric power to the medical devices and for this purpose comprises a power supply unit; the rack shall serve to fix the medical devices for a reliable and secure arrangement and for this comprises connection means to hold the medical devices; and the rack shall serve as a communication spine to provide a communication between the infusion pumps among each other and between the infusion pumps and external periphery devices such as a barcode reader, an external communication network such as a local area network (LAN) and, possibly, via the communication network to a hospital management system.
  • LAN local area network
  • a rack of this kind - for example in an intensive care unit in a hospital environment - in general is arranged at the bedside of a patient and provides an infusion system with multiple infusion pumps and multiple infusion lines providing fluids such as medication or nutrients to the patient. Since the providing of the fluids over the infusion lines, in particular in an intensive care environment of a hospital, may be vital to the patient and therefore may not be disconnected from the patient or the infusion pumps, occasionally the infusion pumps must be moved together with the patient when the patient moves for example to obtain another hospital service at a different location in the hospital, such as an X-ray examination or the like.
  • the patient may be moved together with the complete rack including the infusion pumps attached to the rack.
  • the patient may be moved with the infusion pumps detached from the rack.
  • the first option may pose the problem that the rack together with the devices attached thereto is rather heavy and difficult to handle, due to for example the communication electronics and the power supply unit(s) included in the rack.
  • the rack must be disconnected from local periphery devices such as a printer, a computer, a monitor or the like, a power feed cable must be detached and communication lines such as a network connection must be unplugged. It thus takes time and effort to transfer the rack with the attached infusion pumps into a condition in which it can be moved, and it also takes time and effort to again connect all external devices and lines after returning the rack, including the risk of not correctly establishing all required connections.
  • the second option may pose the problem that the infusion pumps must be held securely when moving the patient.
  • the infusion pumps are simply placed on a patient's bed, which bears the risk that an infusion pump falls down when moving the patient's bed, in particular if multiple infusion pumps are placed on the bed.
  • the arrangement of the infusion lines is altered, bearing the risk that infusion lines are mixed up, confused and disarranged, including the danger of a possible interruption of an infusion line.
  • EP 0 671 178 A1 discloses a medical monitoring system including a wall mounting plate to which a centre support member is rigidly attached using a pair of mounting flanges which engage a pair of integral tracks on a forward surface of the mounting plate.
  • the centre support supports a plurality of module housings, each of which contains module slots for insertion of interchangeable modular components.
  • EP 1 702 649 A1 discloses a medical device for monitoring or therapy purposes including a base station and at least one module attachable to the base station, the module still being fully functional when separated from the basis station.
  • the rack comprises a base part and a holding part which is detachable from the base part, wherein the base part includes the power supply unit and the communication means of the rack and the holding part includes the plurality of connection means for connecting the plurality of medical devices to the rack.
  • the instant invention is based on the idea to divide the rack into two separate functional parts.
  • the first part denoted as base part, serves to combine the main electronic components of the rack, in particular a power supply unit for electrically supplying the medical devices attached to the rack with power and an electronic communication means for enabling the medical devices attached to the rack to communicate with each other and with external devices.
  • the second part serves for mechanically holding the medical devices and, for this, encompasses the connection means used to attach the medical devices to the rack.
  • the holding part is arranged on the base part and functions together with the base part in a normal condition of use, but may be detached from the base part in order to move the medical devices with a patient in case the patient is moved.
  • the holding part can be detached from the base part, such that the medical devices, combined and held in an organized fashion via the holding part, can be moved together with the patient.
  • the medical devices attached to the holding part hence, remain fixedly combined by the holding part in a secure and reliable manner when moving the patient.
  • the holding part may be attached to a bed post or another accessory, and thus the medical devices attached to the holding part can be moved together with the patient in an organized, easy to carry fashion.
  • the weight of the holding part together with the medical devices attached thereto is substantially reduced compared to the weight of a complete rack. Because in addition the space required by the holding part and the medical devices attached thereto is substantially smaller than the space of the complete rack, the handling of the holding part and the devices attached thereto is easy and convenient. Further, since all interface connections providing the connection to, for example, an external power supply line and external devices such as a printer, a monitor or a communication network may be part of the base part, external connection lines such as a power feed line, a monitor cable or a network connection do not have to be detached prior to moving the holding part together with the attached medical devices. For moving, only the holding part is detached form the base part, but all the lines connected to the base part can remain in place.
  • the medical devices to be attached to the holding part preferably are infusion pumps, in particular syringe pumps or volumetric pumps.
  • Syringe pumps also denoted as small- volume pumps, use a syringe (which is actuated in a computer-controlled manner) for pumping a fluid.
  • Volumetric pumps also denoted as large-volume pumps, usually are formed as peristaltic pumps in which pressure is asserted on a rubber tube to move a fluid in the rubber tube.
  • the rack advantageously is to be attached to a stand, such as a post or the like.
  • a fixing means herein may be provided on the base part, and an additional fixing means may be provided on the holding part such that both the base part and the holding part are attached to the stand.
  • the fixing means may be for example a screwing clamp (a clamp which is fixed by a screw), a spring-tensioned clamp (a clamp having a spring exerting a pressure for providing a clamping fixture), a hook, a positive-locking engagement device or any other suitable means for providing a secure and reliable, yet releasable connection between the parts of the rack and the stand.
  • a screwing clamp a clamp which is fixed by a screw
  • a spring-tensioned clamp a clamp having a spring exerting a pressure for providing a clamping fixture
  • a hook a positive-locking engagement device
  • the holding part is connected, in a normal condition of use of the rack, to the base part, wherein the holding part may be detached from the base part to move the holding part together with medical devices attached thereto independent from the base part.
  • the base part and the holding part may comprise connection means for electrically and mechanically connecting the holding part to the base part in a detachable fashion.
  • the holding part - in a connected state of the rack in which the holding part is connected to the base part - is arranged on a top side of a housing of the base part, wherein the connection means of the base part are arranged on said top side.
  • connection means may in one embodiment be formed by at least one first connection element of the base part and at least one second connection element of the holding part, the connection elements being constituted to establish a mechanical connection for mechanically fixing the base part to the holding part and an electrical connection for electrically connecting the base part to the holding part. This is based on the idea to use a single connection element to both establish a mechanical connection and an electrical connection between the base part and the holding part to be attached to the base part of the rack.
  • the base part for this purpose, comprises a first connection element which can be engaged with a second connection element of the holding part, wherein one of the first connection element and the second connection element may be a male connector and the other of the first connection element and the second connection element may be a female connector, the male connector being engagable into the female connector.
  • the holding part can be both electrically and mechanically fixed to the base part.
  • the first connection element of the base part serves to hold and fix the holding part to the base part such that the attachment of the holding part to the base part mechanically is provided via the first connection element.
  • the first connection element also establishes the electrical connection between the holding part and the base part, wherein the electrical connection may include both a power connection for supplying the holding part with electric power and a communication link for establishing a communication connection between the holding part and the base part.
  • the first connection element of the base part herein may be shaped either as a connection cone protruding from a housing of the base part to engage with a connection opening of the second connection element of the holding part or as a connection opening to engage with a connection cone of the second connection element of the holding part.
  • the first connection element of the base part represents a male connector in the shape of a connection cone to engage with a female connector on the side of the holding part.
  • the first connection element of the base part is a female connector into which a male connector on the side of the holding part can be inserted. In general, there is no functional difference whether the male connector is arranged on the base part and the female connector on the holding part or vice versa.
  • the first connection element of the base part and the second connection element of the holding part may establish both a mechanical connection and an electrical connection.
  • the first connection element and the second connection element may in addition comprise mechanical locking means for mechanically locking the at least one first connection element of the base part to the second connection element of the holding part.
  • the first connection element of the base part as a mechanical locking means, may for example comprise a groove to engage with at least one engagement element of the second connection element of the holding part.
  • the first connection element of the base part comprises at least one engagement element to engage with a groove of the second connection element of the holding part.
  • the one engagement element may for example be a ball arranged on the associated connection element, which may be brought into engagement with the groove on the other connection element, such that the mechanical connection between the first connection element and the second connection element is locked once the ball engages the groove.
  • the at least one engagement element in the shape of a ball for example may be arranged on the associated connection element in a pretensioned manner, such that the connection elements of the base part and the holding part may be attached to each other and the at least one engagement element snaps into engagement with the groove once the connection elements are plugged fully into each other.
  • the at least one engagement element may then be locked in its engaging position such that the connection of the connection elements cannot be released without releasing the locking.
  • the holding part may comprise a handle for carrying the holding part after having detached the holding part from the base part.
  • the handle may be pivotable with respect to a body of the holding part such that the handle may be moved into a position in which the holding part can easily be carried when moving a patient.
  • the pivotable handle may also serve to trigger a locking or unlocking of the connection of the holding part to the base part or to a stand in that - dependent on a pivot position of the handle - a mechanical connection between the holding part on the one hand and the base part or the stand on the other hand is locked or unlocked.
  • the handle may be constituted to be in a rest position when the holding part is connected and fixed to the base part.
  • the handle is manually moved into a move position which at the same time causes the mechanical connection of the holding part to the base part to be unlocked such that the holding part can be detached and separated from the base part.
  • the functional separation of the rack into two parts causes the base part to contain all major electronic devices of the rack (in particular the communication means and the power supply unit).
  • each medical device may carry its own battery such that at least for a limited period of time the medical devices can uphold operation.
  • it may be advantageous to also include a battery into the holding part such that an additional electric energy source is provided to secure and prolong operation of the medical devices.
  • the holding part may comprise a wireless communication interface for wirelessly communicating with the base part and/or an external communication network.
  • the wireless communication interface may provide communication, at least to a basic level including essential information and control commands, between the holding part with its attached communication devices and the base part and/or the external network even when the holding is detached from the base part and carried along with a patient separately from the base part.
  • the wireless communication interface for example may be implemented as a wireless local area network (WLAN) connection or a so called bluetooth connection or the like.
