Description

The present invention relates to a support or holding device for positionally secure holding at least one infusion pump during its operation in the carrier or holding device, with at least one intended for holding the infusion pump in a proximal operating position slot. The invention also relates to a carrier or holding system comprising at least one infusion pump and a carrier or holding device according to the invention.

In infusion technology, infusion pumps are well known. As a rule, they convey liquid from a liquid reservoir to a patient by means of a transfer system, to which this liquid is applied, for example, venously. Particularly in the context of intensive care medicine, it is customary for a single patient to operate a plurality of infusion pumps at the same time or even in association with one another. It is customary to arrange the infusion pumps of such a composite during use in or on or by means of a support or holding device to ensure proper operation and proper use of the pump. This is particularly necessary if, for example, in the context of intensive care medicine or surgery, a plurality of infusion pumps is used simultaneously. For example, a plurality of infusion pumps may be disposed and supported on a single infusion stand.

Most currently on the market infusion pump delivery systems are based on a Einhängemechanismus in which the infusion pump or infusion pumps are mounted in a rear part of the mounting system or are. It is disadvantageous in such systems that a user has to perform a relatively complex sequence of movements with the pump in his hand due to the infusion pump being suspended in the system. First of all, the user must find the part of the hanging mechanism attached to the infusion pump and position it on the other part of the hanging mechanism located on the carrier system. This alone is difficult in particular without corresponding practice, since the suspension mechanism is usually located on the rear side facing away from the user of the infusion pump, covered by this and therefore is not readily visible. This is especially problematic when the infusion pump is mounted at or above eye level, which further obscures a view of the Einhängemechanismus. If the two parts of the Einhängemechanismus properly positioned to each other, for attaching the infusion pump, a further movement is necessary, for example, a circular or linear movement to couple the two parts of the attachment mechanism together and thereby lock the pump with the carrier system. The handling described above is disadvantageously quite accurate and also quite difficult.

Based on this, the present invention seeks to minimize the disadvantages of the prior described above or even eliminate, in particular a user a simple, intuitive and almost blind insertion of an infusion pump in a carrier or holding device and optionally a supply-technical coupling of the infusion pump the support or holding device and a secure holding allow it.

This object is achieved according to the invention by a support or holding device for positionally secure holding at least one infusion pump during operation in or on the carrier or holding device, with at least one intended for holding the infusion pump in a proximal operating position slot, characterized in that Slot is provided with a cooperating with the infusion pump when they move from a distal position to the proximal operating position guide structure. It is also achieved by a carrier or holding system comprising at least one infusion pump and a carrier or holding device according to one of the preceding claims with at least one slot provided for holding the infusion pump in a proximal operating position.

In this context, "distal" means carrier or holding device remote and "proximal" means carrier or holding device close.

A slot according to the invention may also be generally designed as a receiving space, in or to which the infusion pump is introduced by a preferably linear movement and wherein or what the infusion pump is held during operation in the operating position. The guide structure according to the invention can be designed in particular in the form of a linear guide. It allows a guide of the infusion pump at least in one spatial direction, preferably in two spatial directions, transversely to the direction of movement.

Advantageous embodiments of the invention are claimed in the subclaims and are explained in more detail below.

An embodiment of the invention is characterized in that the support and holding device comprises a Trägerstrukur and a slot associated with the tray, which in Essentially transversely to the Trägerstrukur of this protrudes. The tray can in particular form when the infusion pump is brought into the operating position with this cooperating guide structure. In particular, the tray may be formed substantially plate-shaped and / or substantially consist of a plate-shaped base body, the proximal end of which is arranged on the carrier or holding device. The opposite distal end can be free and protrude freely from the carrier and holding device. It is a particular advantage that the tray can optically expose the user to the position and / or orientation due to its preferably horizontally oriented flat or plate-like shape with which to transfer the infusion pump from a distal unmounted position to the proximal operating position and insert it into the slot is.

The tray can form a support structure for the infusion pump according to one embodiment, so that it rests in the operating position on the tray and / or held. The infusion pump may also rest on the tray as it moves from the distal position to the proximal operating position. It is of particular advantage that the user does not have to keep the weight of the infusion pump during the entire shipment to the operating position, but can store the infusion pump virtually on the tray.

It is particularly advantageous if the guide structure is provided with an inlet contour tapering from distal to proximal. Such a design facilitates a relative positioning of the infusion pump relative to the corresponding slot and allows insertion of the infusion pump in the slot without view. Also, tilting of the infusion pump and jamming of the infusion pump with the carrier or holding device is safely and inexpensively avoided.

The carrier or holding device may in particular comprise a plurality of slots and a plurality of trays. In this case, one tray can be assigned to one slot in each case. The tray of a first slot and the tray of a second slot adjacent to the first slot may each have a guide structure which cooperates with the infusion pump respectively when placing an infusion pump in the slot located between the first and second trays. The trays can in particular each be identically formed.

An embodiment of the invention is characterized in that the tray has a groove structure and / or a spring structure which engages with the introduction of the infusion pump with a spring structure or groove structure formed thereon. Such tongue and groove systems or structures allow a particularly accurate and simple relative positioning of infusion pump and carrier or holding device.

In particular, the tray on both sides laterally each have a projecting in the lateral direction rail or spring structure. This comes when moving the infusion pump in the operating position and / or is in each case in the operating position infusion pump with a groove-like base of the infusion pump into engagement.

In addition, the tray on the upper side and / or underside have a guide rib and / or a guide groove. When the infusion pump is brought into the operating position and / or when the infusion pump is in the operating position, it can engage or be engaged in each case with a correspondingly formed counter groove or counter-rib of the infusion pump.

In particular, the following advantages can be achieved by the invention:

• - The pump can be largely intuitively inserted by a user without special attention to the orientation of the pump to the slot in the carrier or holding device.
• - To insert the pump in the operating position in the respective slot only one direction of movement is necessary.
• - The self-weight of the pump after placing it on the tray no longer needs to be held by the user.
• - The pump does not have to be correctly positioned to a specific geometry of the slot first, but it is sufficient when it is placed on the tray, from where the further movement of the pump in the proximal operating position is an automatic positioning relative to the slot.
• - Decoupling of the rail geometry by an additional central rib, thus avoiding jamming by oblique placement
• - Easy to clean due to uncomplicated geometry.

In summary, it can also be said that the invention relates to an order system for infusion pumps, which can also be referred to as a rack system or a rack station. The invention enables a user who Infusion pump or multiple infusion pumps easy to insert intuitively and almost blind in the order system or to arrange it. According to the invention, geometries are designed as guides or guide structures on the pump or on the pumps and on the order system, which simplify this insertion or arrangement. In particular, the geometry may include two fins mounted above the slot and / or two side-facing downwardly-acting ramps that pre-position the pump when inserted into a slot in the vertical and facilitate insertion. In addition, radii and / or bevels may be attached to the organizer system and / or to the infusion pumps at certain locations as guides to assist in infusing the infusion pump into the appropriate slot. Finally, alternatively or additionally, a central rib may be provided which positions the infusion pump in the inserted state in the horizontal. A tray can act as a kind of "platform" for the pump and be provided with a geometry, whereby the user can bring the pump with only one movement in the corresponding slot and lock.

• 6 a top down view of a situation according to 2 ,

1 shows an embodiment of a support or holding device 1 a carrier or holding system 2 according to the invention in a perspective view. The carrier or holding device 1 includes a support structure 3 , at the first tray 4 , a second tray 5 and a third tray 6 are arranged. The shelves 4 . 5 . 6 are plate-like elements that are transverse to the carrier or holding device 1 are arranged. They are with their respective proximal end portion of the support or holding device 1 placed or integrally formed therewith while their respective distal end portion is free. Each above the shelves 4 . 5 . 6 is each a slot 7 ( 7A . 7B . 7C ) for an infusion pump 9 educated. From the slots 7A . 7B and 7C are the slots 7B and 7C between each two adjacent trays 4 . 5 . 6 ,

The carrier or holding device 1 fulfills besides its function as a holder for the shelves 4 . 5 . 6 and those in the slots 7 arranged infusion pumps 9 Furthermore, a function as a power supply unit and is to supply terminals 10 provided, the plug-like, each with an infusion pump 9 are connectable.

As in the 2 and 3 is indicated, there is an infusion pump 9 in a distal position and from this in the proximal direction, ie to the support or holding device 1 out, into one of the slots 7 inserted or spent. The infusion pump 9 points to its underside 11 two feet arranged on opposite sides 12 on, each having a groove 13 train or exhibit. Furthermore, in the bottom 11 the infusion pump 9 a central groove 14 introduced (see in particular in the 2 and 6 ). The groove 14 is at the proximal side to an inlet funnel 15 widened. This can be due to a possible horizontal offset of the pump 9 opposite the respective slot 7 a centering and proper positioning of the pump 9 facilitate insertion.

The shelves 4 . 5 . 6 are each formed identically. They consist essentially of a plate-shaped body 16 , the proximal end of the support or holding device 1 arranged and the opposite distal end free and to a front side 17 is trained. Between the proximal end and the front 17 extend a top 18 , a bottom 19 and two opposing lateral sides 20 . 21 ,

On the bottom 19 every tray 4 . 5 . 6 are each two Finns 22 trained during the transfer or insertion of the infusion pump 9 enter into the operating position with this plant and form a management structure. They allow a user to easily position the infusion pump 9 in the vertical and avoid too high threading of the device. Each of the Finns 2 has an insertion bevel 23 which is selected in position and height so that the feet 12 the infusion pump 9 while plugging into the slot 7 and when moving the pump 9 be automatically positioned in the proximal operating position such that they form with a spring of a tongue-and-groove system and laterally on the tray 4 . 5 . 6 , here on its lateral sides 20 . 21 , located projection 24 engage when the infusion pump is spent in the operating position / inserted into the appropriate slot.

Finns 22 have a geometry that ensures easy cleanability of the surface, so do not have sharp edges and corners.

Each of the lateral on the tray 4 . 5 . 6 arranged protrusions 24 has at its inlet side, here at its to the support structure 3 distal side, each one jumping in the vertical direction ramp 25 on. These form a management structure, the intended positioning of the infusion pump 9 when moving to the operating position / inserting into the slot 7 and / or engaging the projections 24 with the provided feet 12 facilitated. In addition, these serve inclined to the tray 4 . 5 . 6 trained ramps 25 as well as the Finns 22 in addition, the infusion pump 9 to pull down too high positioning and thus also on the upper shelf 4 Ensure the feet 12 the infusion pump 9 during insertion are definitely positioned deep enough or below the side feathers 24 immerse and engage with these nut-and-spring-like. In addition, the projections 24 how very good in 6 is shown, inlet side with radii 26 educated. These radii 26 may help you when inserting the infusion pump 9 compensate for this horizontal offset.

The tray 4 . 5 . 6 is also designed with two left and right, opposite the top 18 raised ribs or protrusions 27 each providing a management level 28 form on the infusion pump 9 can slide with its underside and rests in the locked state. The management level 28 has a defined distance to the lower edge of the respective lateral projection / spring 24 and thus ensures a proper vertical positioning of the infusion pump 9 ,

On every tray 4 . 5 . 6 is also in the middle of a rib 29 educated. This is for an engagement in the central groove 14 the infusion pump 9 trained and determined. By engaging the center rib 29 and central groove 14 is a lateral guide of the infusion pump 9 relative to the slot 7 or to the operating position guaranteed. In addition, such a simple and secure jamming can be prevented, which would otherwise occur in a disadvantageous manner, would be the infusion pump 9 only over their side feet 12 horizontally guided and positioned. An inlet contour 30 , present as a radius 30 is formed at the distal end portion of the rib 29 avoids that infusion pump 9 when inserted into the respective slot 7 at the rib 29 comes to a stop and possibly jammed there.

Also, the bottom of the infusion pump 9 at its proximal end with an inlet contour 31 , here in the form of a rounding off 31 , educated. This inlet contour 31 forms a guide structure for the pump 9 and avoid that these when inserted into the respective slot 7 in case of contact with the distal contour of the tray 4 . 5 . 6 jammed.

It is a particular advantage of the invention that the trays 4 . 5 . 6 the user due to their horizontally oriented planar shape visually set the position and / or orientation with which the infusion pump 9 from a distal unmounted position to the proximal operating position and into the slot 7 should be inserted.
