Definitions

  • the present invention relates to coaling gloves and moccasins to be worn on a human hand and foot, respectively, and more specifically to cooling gloves and moccasins comprising a flowing liquid for cooling the gloves and moccasins to a temperature around 0-5 0 C in order to reduce undesired effects from chemotherapy, e.g. loss of naiis and painful skin reactions.
  • a well-known problem associated with chemotherapy treatment is loss of hair.
  • the side effects of chemotherapy depend on the type of chemotherapy and the amount given. Anticipating and managing side effects can help to minimize them and provide the best possible experience for the person receiving chemotherapy. Many patients who undergo chemotherapy are also surprised to learn that their nails become brittle or discolored, crack easily, or even fall off. The only parts of the human body which continue to grow after adulthood is reached are the hair and nails. In other words, if it needs trimming, there is a risk that it will be affected by chemotherapy. If a nail is lost, it can take 6 months or longer for it to grow back. These nail changes are especially common with chemotherapy such as Taxotere (Docetaxel or paclitaxel) and 5-FU (Fluorouracil).
  • Taxotere Docetaxel or paclitaxel
  • 5-FU Fluorouracil
  • WO 98/16176 discloses an apparatus for regulating the temperature of the scatp of a person undergoing chemotherapy.
  • the apparatus comprises a head covering that includes a plurality of flow passages that extend from the edge of the head covering up towards the crown of said covering.
  • US patent No 5,950,234 discloses a cooling pack in the form of a container encapsulating a cooling substance for preventing loss of hair during chemotherapy treatment.
  • the cooling pack may be formed in a bowl shape to cover the scalp portion of the users head.
  • US patent No 4,765,338 discloses a reusable heat exchanging head piece employable with cancer therapy patients in order to cool the scalp zone of the head for preventing hair loss during chemotherapy treatment.
  • US patent No 4,753,242 discloses a skull helmet, which in use, is worn on the head of a patient and receives circulatory cooling fluid to cool the patient's scalp.
  • the helmet is particularly useful when a patient undergoes chemotherapy.
  • US patent No 5,509,801 discloses an oral therapeutic apparatus comprising an oral device formed to be insertable within a patient's mouth and receiving a circulated cooling medium.
  • US patent No 6,315,696 discloses a therapeutic device for use in the treatment and/or rehabilitation of injuries to bodily extremities, such as the hands or feet.
  • a capsule or chamber is provided which is at least partially filled with a Newtonian or non-Newtonian liquid.
  • An area approximating the shape of the extremity, such as a hand, is formed and made an integral part of the capsule such that the extremity may be inserted to move freely within the liquid physically coming into contact with the liquid.
  • WO 99/47011 discloses a thermal glove fitted to a human hand having integrated with a body of the glove a thermal gel-filled pack.
  • the gel pack includes a sealed bladder constructed of a flexible, durable material resistant to heat and rupture.
  • the bladder encloses a thermal gel adapted for repeated heating and cooling for comfort, prosthetic and/or injury preventive use for technical workers, such as computer users and laboratory workers.
  • the prior art does not describe gloves or moccasins adapted for cooling the fingers and toes, respectively, during chemotherapy treatment.
  • the devices disclosed in US patent No 6,315,696 and WO 99/47011 do not make use of any temperature- regulating means during the treatment period.
  • the devices do not include flow passages causing the cooling fluid to flow in the regions adjacent to the nails, and thus the body temperature would inevitably increase the temperature of the cooling liquid giving rise to less efficient cooling. It should be noted that the most efficient treatment is achieved at temperatures between 0 and 5 0 C; at lower temperatures freeze-injuries will appear, and at higher temperatures the treatment is inefficient.
  • US patent No 5,871,526 discloses a light-weight portable temperature control unit integrating a variety of face and body pads that will conform to the various contours of the face and body to aid in the therapeutic treatment of sports injuries and other forms of trauma.
  • the patent does not envisage a system which would be able to cool all fingers or all toes sufficiently well for being suitable in connection with chemotherapy. Importantly, it fails to constantly and uniformly cool all of the fingers and toes simultaneously.
  • the known methods and apparatus for cooling extremities would either not maintain the skin at a constant desired temperature for the duration of extended treatments or otherwise not be suitable for cooling the entire region, i.e. all fingers or all toes.
  • the present invention comprises an apparatus for reducing the undesired side-effects on extremities of a patient being subjected to a chemotherapy treatment, which comprises a hand or foot therapeutic device having an inner contour that conforms to the patient's hand or foot and contacts the patient's fingers or toes.

  • -a cooling unit and a pump for supplying the glove with cooling fluid at a predetermined temperature
  • -tubes for transporting the cooling fluid from the cooling unit to the glove wherein the flow passages are connected in serial or parallel, and which extend along the fingers of the glove.
  • the flow passages are connected in serial. This offers a very simple design since the supply of cooling fluid to the glove may be accomplished by virtue of a single tube connected to one end of the glove.
  • the flow passages may be provided with baffles in order to establish a guided flow around the fingers (see e.g. Figure 1). Such baffles have in some cases proven to be decisive for optimum cooling around the fingers, since they may prevent dead volumes, air bubbles and other undesired fluid dynamics.
  • One aspect of the present invention is that the cooling unit and the glove are connected so as to form a circulating system for the cooling fluid.
  • a simple design may have several advantages including low manufacturing cost and facilitates the disconnection of the glove from the cooling unit, However, such a system may also suffer from the fact that the temperature of the cooling fluid increases when it travels from one end of the glove to the other end.
