Description

DESCRIPTION OF THE FIGURES

[0049] To supplement the description made and with the aim of helping to better understand the characteristics of the invention, in accordance with a preferred example of a practical embodiment thereof, a set of drawings is provided as an integral part of said description wherein, for illustrative and non-limiting purposes, the following has been represented:

[0050] FIG. 1 shows a general view of the device applied to a finger;

[0051] FIG. 2 shows a detailed view of the device as a whole;

[0052] FIG. 3 shows a possible form of embodiment wherein one of the ferrules is a finger cot; and

[0053] FIGS. 4, 5 and 6 show different views of the device wherein the means for generating a stable axial force is by means of compressed air, also using the air as a means of fixing to the body part whereto it will be applied.

PREFERRED EMBODIMENT OF THE INVENTION

[0054] In view of the figures, a preferred embodiment of the proposed invention is described below.

[0055] FIG. 1 shows a finger (1) whose tip is covered by a finger cot (2) containing an anti-inflammatory and/or analgesic gel or pomade disposing, on the part of said finger cot that may be covered, the device strictly speaking, which comprises a first ferrule (3) and a second ferrule (4), both, in the embodiment shown, having a cylindrical hollow configuration and joined by elements by means (5) capable of controllably modifying the distance that separates the ferrules in the manner of elastic rods or straps with shape memory.

[0056] The means (5) capable of controllably modifying the distance that separates the ferrules and generator of a stable axial force may vary, such as thermostretch wires, used like muscles in robotics, or compressed air or any other axial force-generating means or elastic material susceptible of recovering its initial position.

[0057] A material is said to have shape memory when it recovers its shape after it stops applying the external force that deformed it.

[0058] A possible elastic material used to manufacture thermostretch wires may be a wire of a special nickel-titanium alloy which, when the current passes through it or heated, increases in length and is capable of moving or lifting objects. Said wires can be Nitinol® or Flexinol® or any material with elastic memory that allows it to recover its initial shape.

[0059] Nitinol is a material with shape memory that can recover its shape after deforming it in an apparently irreversible way. It is a Ni—Ti alloy known as Nitinol.

[0060] There are housings (3.1) and (4.1) on the first ferrule (3) and the second ferrule (4), respectively, in which to house vibration-generating means (6) and (7), respectively, that may be both a motor associated with an eccentric and an electromagnetic mechanism having an oscillating coil housed in its interior or the combination of both. The vibration-generating means do not have to be disposed on all the ferrules, but rather may be disposed on only one of the ferrules.

[0061] The first vibration-generating means (6) has feed cables (6.1), while the second vibration-generating means (7) has feed cables (7.1), both of which extending from a control unit (8) in charge of adjusting the intensity, phase and speed thereof.

[0062] FIGS. 4 to 6 show an embodiment wherein the programmable elastic means (5) that generate a stable axial force consist of cavities filled with compressed air that produce a force or separation between the ferrules (3) and (4).

[0063] The compressed air can also be used as a means of fixing the ferrules to the fingers.

[0064] It is possible to combine the different means capable of modifying the distance that separates the ferrules (compressed air, thermostretch wires, etc.) with the different means for fixing the ferrules to the fingers (adhesive or by exerting pressure or using a lung or bladder, etc.).

[0065] In the embodiment shown in FIG. 4, which is non-limiting, it can be observed that the first ferrule (3) has a duct (3.2) connected to an inflatable lung (3.3) (FIGS. 5 and 6) to which pressurised air is supplied to ensure the fixation of the ferrule to the finger. The second ferrule (4) also has a duct (4.2) that supplies air to its corresponding lung (4.3) (FIG. 6) and that, once inflated, ensures the fixation of the ferrule to the finger.

[0066] The means (5) capable of controllably modifying the distance that separates the ferrules have a duct that supplies air (5.1) to conduits inserted between the ferrules (3) and (4) such that the separation between the ferrules varies in accordance with the air pressure supplied, i.e. they generate a stable axial force.

[0067] Having sufficiently described the nature of the present invention, in addition to the manner in which to put it into practice, it is hereby stated that, in its essence, it may be put into practice in other embodiments that differ in detail from that indicated by way of example, and to which the protection equally applies, provided that its main principle is not altered, changed or modified.
