Abstract
Description
Technical Field
[0001] The present invention relates to a device for quick attachment of biomedical devices (particularly relating to vehicles for transporting medical devices, such as, for example, automobiles or airplanes). Background Technology
[0002] The equipment being transported is known to include in-hospital and out-of-hospital biomedical devices, such as devices for extracorporeal blood circulation, like oxygenators and centrifugal pumps, or other devices for hospital practice and emergency situations.
[0003] More specifically, while these devices are widely used in hospital practice, they also need to be used in emergency situations such as roadside aid or in places far from adequate sanitation facilities.
[0004] For example, an important aspect of patient treatment involves transportation between hospitals, specifically from hospitals with lower levels of care to those with higher levels of care. On the one hand, such transportation is often necessary for the patient's recovery. However, on the other hand, such transportation poses a high risk to the patient themselves.
[0005] In these cases (which are typically characterized by cardiovascular insufficiency), miniaturized and transportable cardiopulmonary bypass systems are needed to provide adequate early treatment.
[0006] In fact, the infusion systems used in hospital practice are not designed for long-distance transport. They are often too large and bulky, and therefore unsuitable for small spaces and when time (as well as the speed of preparing rescue equipment) is critical.
[0007] Furthermore, when used in automobiles and airplanes (where they are typically subjected to strong positive or negative acceleration), these known systems pose a risk to the safety of patients and healthcare workers. Under these conditions, there is a risk that devices used for emergency care may detach and injure patients or caregivers.
[0008] To overcome these drawbacks, support devices for the injection system have been designed, which are suitable for use in land and aircraft rescue vehicles.
[0009] One of these devices is known according to EP 2635318, which describes a support plate that can be fixed to a holding surface (such as the base plate of an emergency vehicle) and provides multiple support devices for various biomedical devices.
[0010] Another device of the known type is described by US 2019 / 0269477.
[0011] However, these known devices do have some drawbacks.
[0012] In fact, their preparation was not easy.
[0013] In particular, it will take medical staff too much time to prepare the biomedical device on the support plate.
[0014] Furthermore, if any of the support devices is damaged or malfunctions, the relevant biomedical device may detach from the support plate, thus affecting the proper operation of the perfusion system. Summary of the Invention
[0015] The primary objective of this invention is to design a device for the rapid attachment of biomedical devices, which allows for the easy and safe attachment of the biomedical devices required for care to a transport vehicle (such as a land or air vehicle) in emergency situations.
[0016] Within this objective, one objective of the present invention is to design a device for rapid attachment of biomedical devices that allows for easy preparation by responsible personnel, thereby reducing rescue time.
[0017] Another objective of this invention is to ensure the safe transport of biomedical devices in order to minimize the risk of damage or harm to responsible personnel.
[0018] Another objective of this invention is to design a device for rapid attachment of biomedical devices that allows for overcoming the aforementioned disadvantages of the prior art with a simple, rational, easy, effective, and low-cost solution.
[0019] The above-described objective is achieved by the device for rapid attachment of a biomedical device according to claim 1.
[0020] These objectives are also achieved through the device for rapid attachment of biomedical devices as described in claim 18. Brief description of the attached diagram

[0029] With particular reference to these accompanying drawings, reference numeral 1 throughout indicates equipment for quick attachment of biomedical devices, and reference numeral 40 throughout indicates apparatus for quick attachment of biomedical devices (particularly vehicles for the transport of medical devices).
[0030] According to the invention, the device 40 includes a base element 2, which is associated with a support plane S and defines a guide seat 6 extending along a sliding direction 3.
[0031] Therefore, device 1 includes a device 40 and at least one anchoring element 4, which is associated with one or more biomedical devices O, P and can be inserted into guide seat 6 by displacement along sliding direction 3.
[0032] Biomedical devices O and P include, for example, an oxygenator O for extracorporeal blood circulation and an associated pumping assembly P, which are associated with support components for biomedical device 30. Anchoring element 4 is then associated with the support components for biomedical device 30 at a specific point (where its bottom wall is positioned by an associated fastening member, such as a threaded fastening member).
[0033] In the embodiment shown in the accompanying drawings, the base element 2 includes a load-bearing element 10 associated with a support plane S and a guide element 11, which is locked together with the load-bearing element 10 and defines a guide seat 6.
[0034] The supporting plane S includes, for example, the floor of a transport vehicle, such as an ambulance, helicopter, or other mobile rescue vehicle.
[0035] Appropriately, the device 1 includes removable attachment devices 20, 23 for attaching the base element 2 to the support plane S.
[0036] More specifically, attachment devices 20, 23 include a first attachment device 20, which is movable along the adjustment direction indicated by double arrows 24 in the figures. The first attachment device 20 includes one or more slots 21 and one or more engaging elements 22, the slots 21 extending along the adjustment direction 24, and the engaging elements 22 slidably inserted into the slots 21 to lock the base element 2 to the support plane S. Preferably, the adjustment direction 24 is arranged transverse to the sliding direction 3.
[0037] In the embodiment shown in the accompanying drawings, the slot 21 is defined on the load-bearing element 10.
[0038] Because multiple attachment rods F are usually mounted on the support plane of emergency transport vehicles (such as ambulances, rescue helicopters, etc.), and the distance between them can be changed depending on the situation; the engagement element 22 is configured to slide along the slot 21 to accommodate the position of the attachment rods described above.
[0039] Multiple attachment rods F extend along the sliding direction 3 and are arranged to be generally parallel to each other.
[0040] Therefore, in order to allow engagement with the attachment rod F, the slot 21 extends in a direction transverse to the sliding direction 3.
[0041] Advantageously, the attachment device 20 also includes a second attachment device 23 (e.g., an additional engagement element type) attached to the support plane S, the second attachment device 23 being manually movable between an engaged position and a released position. The second attachment device 23 is attached relative to the base element 2. In the embodiment shown in the figures, the second attachment device 23 is also associated with the load-bearing element 10.
[0042] Still according to the invention, the device 40 includes a removable locking device 5 for an anchoring element 4 associated with a base element 2, wherein the locking device 5 is adapted to prevent the anchoring element 4 from shifting relative to the base element 2 upon reaching a predetermined anchoring position. The predetermined anchoring position corresponds, for example, to the end position of the travel of the anchoring element 4 on the base element 2. In particular, the base element 2 has a stop surface 2a, and the predetermined anchoring position corresponds to the position occupied by the anchoring element 4 when it rests on the stop surface 2a.
[0043] Meanwhile, the guide seat 6 is shaped to prevent the anchoring element 4 from lifting.
[0044] Advantageously, the base element 2 defines at least one retaining surface 2b and at least one anchoring surface 2c, the at least one retaining surface 2b being adapted to support the anchoring element 4, and the at least one anchoring surface 2c facing the retaining surface 2b and being adapted to prevent the anchoring element 4 from lifting relative to the base element 2 in use.
[0045] More specifically, the guide seat 6 is generally C-shaped, and its lower and upper parts are defined by the retaining surface 2b and the anchoring surface 2c, respectively.
[0046] In other words, by inserting itself inside the guide seat 6, the anchoring element 4 is adapted to engage the base element 2 by displacement along the sliding direction 3. The guide seat 6 also defines lateral constraint walls 6a, which are arranged adjacent to each other and transverse to the anchoring surface 2c.
[0047] In the embodiment shown in the accompanying drawings, the locking device 5 is associated with a guide element 11, which defines a stop surface 2a, a retaining surface 2b, and an anchoring surface 2c and is adapted to engage the anchoring element 4.
[0048] Preferably, the locking device 5 includes at least one locking element 15, which is movable between a locked position (where it is adapted to interact with the anchoring element 4 to prevent the anchoring element 4 from shifting along the sliding direction 3) and a released position (where it allows the anchoring element 4 to shift along the sliding direction 3).
[0049] Conveniently, the locking device 5 includes a resilient device 7 adapted to counteract the displacement of the locking element 15 from the locked position to the released position.
[0050] More specifically, due to the sliding of the anchoring element 4 toward the predetermined anchoring position, the locking element 15 is adapted to move from the locked position to the released position; and upon reaching the predetermined anchoring position, it is adapted to move from the released position to the locked position due to the action of the elastic device 7.
[0051] Therefore, the locking element 15 is pushed to the release position due to its interaction with the anchoring element 4 during its forward movement toward the predetermined anchoring position; while when the anchoring element 4 reaches the predetermined anchoring position, it is independently moved to the locking position.
[0052] Advantageously, the locking element 15 has at least one locking surface 15a and at least one contact surface 15b, the at least one locking surface 15a being adapted to interact with the anchoring element 4 at a predetermined anchoring position to prevent it from shifting along the sliding direction 3, and the at least one contact surface 15b being positioned inclined relative to the sliding direction 3 and adapted to interact with the anchoring element 4 during its shifting toward the predetermined anchoring position; the locking element 15 is thus shifted from the locked position to the released position due to the interaction between the anchoring element 4 and the contact surface 15b.
[0053] More specifically, the interaction between the anchoring element 4 and the locking element 15 generates a force with a lateral component relative to the sliding direction 3, causing the elastic device 7 to compress.
[0054] like Figure 2 and Figure 5 As shown, the anchoring element 4 then has at least a first end portion 4a and a second end portion 4b opposite to each other. The first end portion 4a is adapted to interact with the contact surface 15b during its displacement along the sliding direction 3 inside the guide seat 6, so as to move the locking element 15 from the locked position to the released position. The second end portion 4b is adapted to interact with the locking surface 15a at a predetermined anchoring position to prevent the anchoring element itself from moving away from the stop surface 2a along the sliding direction 3.
[0055] Advantageously, the locking device 15 includes at least two locking elements 15, which are spaced apart from each other in a locked position relative to a released position. An elastic device 7 is located between the locking elements 15 and is adapted to push them to the corresponding locked position.
[0056] Appropriately, the contact surfaces 15b of the locking elements 15 are arranged to be offset outward from each other when they move closer to the predetermined anchoring position.
[0057] In this embodiment, the device 1 includes two anchoring elements 4, which are arranged to be transversely spaced from each other relative to the sliding direction 3.
[0058] More specifically, the locking element 15 is located between the anchoring elements 4 during use (i.e., during the forward movement of the anchoring element 4 along the sliding direction 3 and at the predetermined anchoring position).
[0059] The operation of this invention is as follows.
[0060] First, the base element 2 is attached to the support plane S using attachment devices 20, 23. In particular, once the load-bearing element 10 is positioned above the attachment rod F described above, the position of the engagement elements 22 is adjusted along the slot 21 such that they are brought to the attachment rod itself and then engage with each other.
[0061] After the connecting element 22 has been attached to the attachment rod F, an additional attachment element 23 is attached.
[0062] Then, the support device for the biomedical device 30 is attached to the anchoring element 4, and the anchoring element 4 is attached to the base element 2.
[0063] More specifically, after the anchoring element 4 (which is applied to the bottom of the support device for the biomedical device 30) is aligned with the anchoring element 11, the anchoring element itself moves forward along the sliding direction 3. The anchoring element 4 interacts with a corresponding first end portion 4a having a locking element 15, specifically having a corresponding contact surface 15b (by moving them from a locked position to a released position). After the anchoring element 4 reaches the predetermined anchoring position (defined by the stop surface 2a), the locking element 15 is automatically moved to the locked position by the action of the elastic device 7, wherein the corresponding locking surface 15a interacts with the corresponding second end portion 4b of the anchoring element 4 and prevents it from moving along the sliding direction 3. The stop surface 2a then prevents the anchoring element 4 from sliding further along the sliding direction 3. At the same time, the anchoring surface 2c prevents the anchoring element 4 from lifting.
[0064] If it is necessary to remove the biomedical device O, P or move it relative to the base element 2, the locking element 15 can be manually moved from the locked position to the released position, so that the anchoring element 4 can move away from the predetermined anchoring position along the sliding direction 3, that is, away from the stop surface 2a.
[0065] In practice, it has been confirmed that the described invention achieves its intended objectives; and it is particularly emphasized that, due to the construction of the guiding elements and locking devices, the device involved in the invention allows for the attachment of biomedical devices required for performing cardiovascular rescue in emergency situations to rescue transport vehicles (land or air type) in a practical and easy manner.
[0066] In particular, the anchoring surface and locking device allow operators to attach biomedical devices to the guiding element in an extremely rapid and safe manner, enabling the preparation and safe transport of necessary rescue equipment in a short time. Simultaneously, the locking device is designed to allow for rapid removal for use on stretchers or hospital beds.
