Scope

In its most general aspect, the present invention relates to a cart for aspiration systems.

In particular, this invention can be applied potentially, but not exclusively, in the field of medical and hospital care and even more particularly in all continuous medical aspiration applications in hospitals and clinics.

State of the art

As is well known in this particular technical field, surgical aspirators are used during and after surgical procedures to remove surgical fluids, tissues (including bones), gases, and bodily fluids.

These fluids are placed in special collection containers for later disposal. The collection containers are generally composed of a disposable collection bag for the aspirated fluids, a rigid container into which said bag is inserted and one or more connectors to receive said aspirated fluids.

The use of these collection containers is sometimes not very practical for healthcare professionals who have to use them.

Often times, it is also necessary to adopt more collection containers during a single operation to obtain more fluids or to accommodate different collection needs.

Furthermore, especially when using several collection containers, there are often problems due to simultaneous use in coupling with the suction system.

In addition, several devices are generally adopted in suction operations, such as vacuum regulators, safety containers, Venturi aspirators, etc., each of which must be connected according to the various requirements even during the same intervention.

To meet the aforementioned needs, various transport and connection systems have been developed for use in conjunction with surgical aspirators.

However, these solutions still present limitations in terms of adaptability to all the operations required in the aspiration of fluids.

Consequently, the objective of the present invention is to devise a device that guarantees comfort and versatility of use, while overcoming the limitations of the solutions currently proposed by the known art.

Another objective is based on providing a device that is suitable for a plurality of intervention cases through specific adaptations.

Another objective is based on providing a device that also allows rapid transport of the adopted components.

Finally, the object of the invention is to provide a device that is simple to manufacture.

Detailed description

With reference to the attached figures, the number 1 indicates, in general terms, a trolley for aspiration systems according to the present invention.

In particular, the carriage 1 comprises a support bar 2 engaged in a displacement system with wheels 3.

The displacement system with wheels 3, in the present embodiment, comprises a radial frame 4, which in this case comprises five arms 5, at the ends of which the respective wheels 6 are arranged.

Preferably, the wheels 6 provide a rotating support in order to allow an omnidirectional movement on the surface, facilitating the transport phase of the trolley 1.

More preferably, the wheels 6 can be antistatic, which protects the operator from electrostatic discharges generated by the equipment being transported.

Even more preferably, at least two wheels 6 are provided with a locking pedal (not shown), to allow the carriage 1 to be positioned in an easy, rational and stable manner.

There is nothing to prevent providing a displacement system 3 configured differently.

On the bar 2 there is provided at least one support 7 for a collection container suitable for containing the fluids drained to the patient. In the present embodiment, four supports 7 arranged in a cross are provided.

The supports 7 can be in the form of cantilevered shelves on which only the collection containers are placed.

Alternatively, the supports 7 may be shaped in the shape of a ring, to provide the introduction of the collection containers, and specifically the rigid containers, thus coupling the support 7 with the lid of the collection container and guaranteeing greater stability in the transport phase.

The supports 7 are preferably removably associated with the support bar 2 to be able to provide different configurations of the carriage 1.

In the present exemplary embodiment, each support 7 is associated with the support bar 2 by means of a corresponding quick fastening system 8, in this case represented by a slide system, as shown more clearly in the figure 2. Consequently, the quick fixing system 8 comprises a rail 8A in which a corresponding sliding element 8B is inserted from above on the support 7 and within which it slides to a stop position. The decoupling is clearly effected by a reverse movement. Figure 2 specifically shows an embodiment in which a quick fastening system 8 is placed in correspondence with a selection system that is described in more detail below, this variant being included in the scope of protection defined in the appended claims .

In the upper part of the carriage 1 a multifunction head 9 is provided that incorporates a body 9A.

Different instruments adopted in the suction phases can be coupled to the head 9.

A vacuum regulator is specifically depicted in FIG. 1.

However, as can be seen in figure 3, it is possible to associate different devices to the head 9 depending on contingent needs.

Specifically, a vacuum regulator and a flow meter are shown by way of example, but nothing prevents the application of suction devices with a Venturi system and supplied with compressed air or other devices.

To obtain this connection, in particular, the head 9 includes a removable connection system 10 for any device for measuring or regulating the suction.

The removable connection system 10 comprises a housing 11 directly on the head 9 and a connection element 12 on the device to be coupled.

Therefore, the connecting element 12 can be fitfully engaged in said housing 11.

As can be seen more clearly in Figures 4A, 4B, 5A and 5B, in the present embodiment the removable connection system 10 provides a quick release mechanism when the connection element 12 is rotated in the respective housing 11.

In particular, the connecting element 12, which here has a cylindrical configuration, provides a pair of arcuate perimeter projections 13 and a widened upper end portion 24. The pair of perimeter projections 13 and the widened upper end portion 24 are parallel to each other. yes and transverse with respect to the insertion direction D of the connection element 12.

The term "upper" refers to a positioning of the carriage 1 in a vertical position with the wheeled displacement system 3 arranged on the ground.

The housing 11, also cylindrical, also provides a perimeter groove 14 in correspondence with the pair of perimeter projections 13 of the connection element 12 when the latter is fully inserted in the housing 11.

Furthermore, the housing 11 in correspondence with the opening 15 provides a pair of perimeter recesses 16 that allow the insertion of the pair of perimeter projections 13 until it stops in the perimeter groove 14.

As the connecting element 12 rotates, the perimeter projections 13 no longer correspond to said perimeter recesses 16 and are therefore locked within the perimeter groove 14.

By rotating in the opposite direction, a repositioning of the perimeter projections 13 is clearly obtained in correspondence with the perimeter recesses 16, which allows disengagement.

The body 9A of the head 9 contemplates a through conduit 9B that has the housing 11 at one of its ends. Therefore, the connecting element 12 also acts as a closure for said through conduit 9B.

Furthermore, in the embodiment shown, the lower part 17 of the connection element 12 is shaped like a cup, engaging in a respective recess 18 in the body 9A of the head 9 parallel to the through conduit 9B.

Alternatively, it is possible to provide a removable connection system 10 that provides a snap-release mechanism, with deformable fins on a connection element and respective recesses in the housing in order to obtain a stronger connection.

There is nothing to prevent the adoption of other alternative latching mechanisms between the head 9 and the various control components of the suction system.

The head 9 comprises at least one vacuum suction inlet 19 adapted to be coupled to a vacuum tube for suction operations.

There is nothing to prevent adopting a plurality of vacuum suction inlets 19 in accordance with various requirements.

The suction flow from the vacuum suction inlet 19 into the body 9A of the head 9 acts on at least one vacuum suction outlet 20. Therefore, the vacuum suction outlet 20 can be connected to one of the containers of collection placed on at least one support 7.

In the present embodiment, a plurality of vacuum suction outlets 20 are provided. In this way it is possible to provide for the sequential or simultaneous use of several collection containers.

In this case, preferably, the head 9 further comprises an outlet selection system 21 for the plurality of vacuum suction outlets 20 in order to be able to select one or more determined collection containers.

In the present embodiment, the outlet selection system 19 comprises a valve system (not shown) actuated by a plurality of actuation buttons 22.

By turning the knobs between an open and a closed position and vice versa, it is therefore possible to select the vacuum path from the vacuum suction inlet 19 to at least one of the plurality of vacuum suction outlets 20.

Specifically, the buttons 22 make it possible to feed or not, through the vacuum source, each collection container. These collection containers can then also be connected in tandem; that is to say, connecting both the power supplies in parallel to balance the distribution of the suction in each of the same containers, as well as the ducts that carry the sucked fluids into their interior in cascade to increase the fluid collection capacity. Therefore, the operator can stop feeding the collection containers when the liquid level reaches the maximum collection limit. In this case, a so-called "overflow system" can be envisaged, which allows, above all through the use of a hydrophobic filter, to lower the mechanical pressure derived from the thrust of the liquids present in the filtration membrane, thus guaranteeing total efficiency. .

In addition, the head 9 includes a grip handle 23 for a further displacement. comfortable around the trolley 1.

Advantageously, the present invention allows suction operations to be carried out efficiently and rationally, grouping in a single system all the elements necessary for its use.

The system provides operators with the most suitable solution for use in a hospital environment.

The trolley for suction systems according to the invention, therefore, makes it possible to connect any suction control and regulation device to the terminal units arranged on the head.

Furthermore, advantageously, the slide fixing system arranged on the bar also makes it possible to house more collection containers for aspirated fluids.

Likewise, it is possible to provide other optional add-ons, such as fastening elements to fix the so-called "probe support tubes"; that is, other containers, generally cylindrical, for example, in polycarbonate, for each of the predisposed suction circuits, in order to allow the operator to store the tube with the patient's aspiration probe after use.

Therefore, advantageously, both at the level of control and regulation devices and at the level of elements merely suitable for collection, the carriage 1 can be easily and quickly reconfigured to provide the best support for each specific suction operation.

Furthermore, advantageously, the use of the carriage 1 is particularly intuitive, since it does not require particular instructions for the operators who are going to use it.

More advantageously, the carriage 1 is simple to manufacture from the point of view of production, since it is made by means of a series of individual components that can be easily assembled together.

It will be apparent to those skilled in the art that modifications and variations may be made to the present invention, all being contemplated within the defined scope. per the appended claims.

For example, nothing prevents the replacement of some components, such as the displacement system presented, by others that are more efficient for specific applications.
