Definitions

  • the complete apparatus may be located in an unobtrusive position such that it does not interfere with the surgical team
  • the device is nonetheless bulky, must be orientated over the patient thereby reducing proper normal lighting of the patient and also reducing the number of lines of sight and access to the patient.
  • Other heating means such as the use of convection currents or central air-conditioning also have numerous drawbacks. Such means will also warm the surrounding environment excessively and result in overheating of the surgical or hospital room staff and will also result in excessive energy usage.
  • Air convection units are also bulky and take up considerable valuable space in the operating room, requiring extended wires and heating hoses that create obstacles to free movement around the patient during surgery.
  • the present invention is a table comprising a solid surface having pads affixed on the top of said solid surface, said pads comprising at least one surface comprising a cavity wherein at least one said cavity comprises wires adapted to transmit an electrical current such that transmittal of said electrical current through said wires raises the temperature of said wires, and wherein said pads are adapted to transmit the thermal energy created by said transmittal of said electrical current through said wires to said solid surface and to the surface of said pads.
  • the table comprising pads provides a minimal footprint.
  • FIG. 1 is cross-sectional schematic of one embodiment of the invention in which a patient is lying on a series of pads disposed on a solid surface which is disposed on or part of a table.
  • Fig. 2 demonstrates one embodiment of the invention detailing an operation of a control circuit.
  • a patient 104 may be situated onto at least one pad 100.
  • the patient may have only a specific body part resting on a pad 100 such as a head, the torso, arms, or legs while another body part or parts (not shown) may rest directly onto the solid surface 102.
  • the solid surface 102 may comprise a single pad 100 or a series of pads 100 disposed on the solid surface.
  • a single large pad 100 may be disposed throughout the entire length and width of the solid surface 102 or some lesser portion thereof.
  • the pad or pads 100 may be disposed on the solid surface in a number of manners.
  • the pads may be affixed permanently to the solid surface.
  • the pads may be affixed using VELCRO or another fastening means such as with plugs, clips, screws, latches, and so on.
  • the pads are affixed via magnets.
  • a magnet may be disposed on the four corners of a pad and be attracted to a magnetically reactive substance or substances in the solid surface.
  • the magnet may be in the solid surface and the magnetically reactive substance may be in the pad.
  • the use of a magnet is advantageous because the pads can be easily positioned onto the solid surface in a number of arrangements. Further, magnets inside the pad or solid surface are hygienic and can help maintain sterility.
  • the solid surface itself may be affixed or disposed on another table or support structure 106.
  • the solid surface may be a single large slab or may comprise a number of smaller solid surfaces which are joined together. Such an arrangement is preferred for hospital room usage where the table must be adapted to allow adjustment or orientation of the patient.
  • Small solid surfaces can be joined in numerous manners, including hinges, that allow for the free movement of one solid surface relative to another.
  • the solid surface is non-porous, has a low dielectric constant (to minimize the accretion of dust and other electro-statically attracted substances), and does not promote bacterial or microbial growth.
  • the table is made of an acrylic resin and may contain antibacterial substances such as titanium dioxide in order to retard, inhibit, or prevent bacterial growth.
  • the solid surfaces may also be adjoined to another table via a variety of means including an epoxy resin or traditional joining means such as screws, latches, joints, and so on.
  • the pads may be filled with any type of material conducive to the transmittal of electrical current.
  • Such materials include wire and may include wire made of metals.
  • copper, nickel, nickel and chromium blends or nickel with chromium coats, or silver wire may be used.
  • a carbon based compound may also be used. Any of the foregoing metals or carbon compounds may also be comprised as a coat on nylon or polyester threads as a suitable pad filling and may even be integrated into the fabric weaving.
  • the fabric weaving may also integrate computer chips and other circuitry such as light emitting diodes (“LEDs”), liquid crystal displays (“LCDs”), alpha-numeric displays, or other outputs to provide means for information processing, input/output control, and signaling.
  • LEDs light emitting diodes
  • LCDs liquid crystal displays
  • alpha-numeric displays or other outputs to provide means for information processing, input/output control, and signaling.
  • an alloy or mixture of metals and optionally non-metals may be used.
  • Such materials may also be filamentous.
  • Such materials may also be weaved into, through, or on the pads. Such materials may also fill the cavity of the pad.
  • the pads comprise a fibrous material having a high resistance.
  • a specific advantage of using fibrous or filamentous materials having a high resistance is that they have been found to allow maximal heat generation while requiring only minimal voltage. Such fibrous or filamentous materials are therefore preferably selected from the class of such materials having high resistance.
  • Such materials may be admixed or comprise in part materials have a low resistance.
  • the pad's fibrous material is adapted to receive a low voltage such that the risk of electrocution or other electrical harm is minimized and yet provide sufficient thermal output to warm a patient.
  • a low voltage is defined as a voltage at least sufficient to provide a non-negligible warming of the pad but no higher than a voltage which would be considered unsafe if a patient were exposed to said voltage.
  • the pads may comprise, in addition to electrically conducting materials, non-electrical conducting materials including insulation.
  • the insulation is adapted to allow maximal conduction of heat.
  • the insulation is adapted to provide support to the pad such that the pad does not unduly compress when a patient is placed thereon.
  • the pads also comprise a number of thermistors. These thermistors are adapted to register the heat output of the pad at number of locations.
  • the thermistors may be linked to the electrical system comprising the energy delivering source of the pads such that a high temperature will automatically deactivate the pad or pads. For example, a change in resistance in a thermistor will indicate a change in temperature in the vicinity of the thermistor.
  • a control circuit which is calibrated to the temperature/resistance ratio of the thermistor will determine if the temperature of a thermistor is registering an inordinately high temperature. If so, the control circuit will deactivate heating of the pad or pads.
  • the control circuit can also detect a low temperature and raise the temperature of the pad by increasing the voltage passing through the pad's resistive elements.
  • Fig. 2 indicates such an arrangement.
  • Thermistor 108 sends an electrical signal which varies according the temperature of the thermistor 108 to the control circuit 110.
  • the thermistor reading is checked against a set high temperature point. If it is high, the control circuit 110 may lower the voltage (if the temperature is sub-critical) or stop the voltage entirely (if the temperature is critically high). If the temperature is not high, then the control circuit 110 determines whether the temperature is low. If the temperature is low, the control circuit can raise the voltage directed to the heating elements in the pad to raise the temperature of the pads.
  • some thermistors may be adapted to detect the heat temperature of a pad and transmit such a signal to a readout. Such a readout could be used to read the temperature of the pad.
  • some thermistors may be adapted to detect the heat temperature of the outer surface of the pad wherein a patient's body part may rest. The detected heat temperature would be transmitted to a readout which would inform persons of the temperature of that region of the patient. Such a readout may be calibrated to determine the temperature of the patient as a whole. For example, a number of thermistors could detect the temperature of the patient at various points and the collected data temperature could be transformed into a single averaged or calibrated temperature of the patient.
  • the patient may be human or non-human including mammals.
  • certain terms and visual depictions are used to illustrate the preferred embodiment. However, no unnecessary limitations are to be construed by the terms used or illustrations depicted, beyond what is shown in the prior art, since the terms and illustrations are exemplary only, and are not meant to limit the scope of the present invention. It is further known that other modifications may be made to the present invention, without departing the scope of the invention, as noted in the appended claims.
