Description

BRIEF DESCRIPTION

[0014] Some of the embodiments will be described in detail, with reference to the following figures, wherein like designations denote like members, wherein:

[0015] FIG. 1 corresponds to the needle with nanomaterial in small caliber being introduced in the veins or arteries of the patients, wherein the activation of the nanosensor located inside thereof (optical effect by LED light), activates the nanomaterial so its original state (latex molecules bound together to each other with the minimum distance therebetween) is modified by a transitory state consisting of a measurable increase of the distance between the latex molecules which allows the diameter to be increased.

[0016] FIG. 2 corresponds to the probe manufactured with nanomaterial in small caliber being introduced in the urethra of patients (vesicle probe), wherein the activation of the nanosensor located inside thereof (optical effect), activates the nanomaterial to increase the diameter of the probe. Note the option of external manipulation of the nanosensor which allows the control of the diameter by the health personnel.

DETAILED DESCRIPTION

[0017] Embodiments of invention corresponds to a device (1) for a variable diameter hypodermal needle (2), wherein the diameter of said needle (2) varies through the use of nanotechnology, since it is manufactured in a latex-derived nanomaterial which chemical composition is fundamentally based in fats, waxes and diverse gummy resins obtained from cytoplasm of lactic cells. This biochemically modified material goes from an original state to a transitory state consisting of a measurable increase of the distance between the latex molecules which allows the diameter to be increased, i.e. it enlarges or shrinks according to the needs of the patient, wherein such device corresponds to a needle or the like, which allows to have a very small diameter to be able to be inserted in the patient and then through an excitation of said nanomaterial, it can be enlarged once inserted so as to allow the intake of fluids to the body through a catheter or the like. Thus, the fluid transfer device after being used can return to its reduced diameter so that it can be removed from the patient avoiding pain and trauma risks in the skin, arteries, veins and other organs of the anatomy.

[0018] The fluid transfer device (1) further comprises the following components or parts: [0019] A sensor (3); [0020] A container (5) for storing the liquid to be injected to removed; [0021] A control system (8) directly connected to the sensor (3); and [0022] A power source (7) which provides the necessary power to all the elements.

[0023] In an embodiment of the present invention, the expansion of the needle (2) is achieved through a source of light (3), such as an LED source, which is located inside the needle (3) and which can be even thinner than a human hair. Thus, once the light is activated inside the needle, said stimulus allows the molecular excitation of the latex atoms which change its biochemical composition by a distancing therebetween which is macroscopically translated in the diameter enlargement of said needle (2), at the same time, the deactivation of the optical stimulus can contract the diameter, by a change in the organization of the latex nanomaterial molecules inside the needle (2), as well as any catheter or probe (material resilience which allowed its return to the original dimensions).

[0024] In an alternative embodiment, the diameter change of the needle (2) is achieved through the temperature change between the environment outside and inside the cavities of the human body where there is a temperature gradient. Thus, when inside the human body, the temperature is greater than the room temperature, whereby the inside of the hollow body dilates.

[0025] In another embodiment of the invention, the molecular alteration of the needle (2) nanomaterial is achieved by means of application of energy from an external device (not shown) which alters the needle (2) molecules through the modification of the electric or magnetic charge.

[0026] Now, in an embodiment of the invention, the needle (2) penetrates the vein of a donor through the use of a biotechnology sensor made of plastic or other nanomaterial, thus by having the ability to change the diameter, the needle (2) starts as a very small container at the moment of performing the penetration and grows in diameter when a command is sent (or after a predetermined time) to guarantee the painless blood donation, avoiding a discomfort in the patient or donor.

[0027] In another embodiment of the invention, the diameter change can be achieved with the command of nano-sensors which sense the gradient of the blood flow. Thus, a bioplastic material which is contained inside a nano-sensor senses the arrival of blood flow when contacts the vein. After a predetermined period of time, as short as a millisecond, the nano-sensor activates a structure change in the original diameter of the needle (2) and generates the enlargement of the polymer (latex) molecules being part thereof.

[0028] In this regard, once the nano-sensors of the needle (2) detect the interruption of blood flow, the material memory is activated returning to its original configuration. Thus, the needle (2) is removed from the vein of the patient with the same original size and it only grows when is inside the blood vessel.

[0029] Now, as previously stated, the change in the diameter of the needle (2) can be activated by means of an electric gradient, wherein a bioplastic material responds to a molecular configuration, mediated by an electric current. In this configuration, the needle (2) changes its diameter when the user activates an electric device near the puncture site, which alters the molecule distribution and the subsequent diameter.

[0030] Similarly, the diameter change can be achieved through induced magnetic fields, wherein the molecular configuration of a bioplastic changes when magnetic devices are activated during the blood donation or patient care.

[0031] According to the above, the polymers modified with nano and biotechnology can respond to temperature, electric, or magnetic changes or directly mediated by nano-sensors, such as those found in micro-robots, smart fabrics, and fibers and products related to space engineering.

[0032] Although the present invention has been disclosed in the form of preferred embodiments and variations thereon, it will be understood that numerous additional modifications and variations could be made thereto without departing from the scope of the invention.
