Definitions

  • the invention is related to a“glove type tens device having a temperature tracking system” that has been designed to concurrently prevent the formation of neuropathies arising from chemotherapeutic agents.
  • Colon cancers, breast cancers, and lung cancers are some of the most frequently observed cancer types. Nerve damage is called neuropathy. Neuropathies can emerge depending on several reasons. Neuropathy can progress at an acute (early) or a chronic (late, long term) stage. One of the reasons for neuropathy is some chemotherapy drugs that are used in treating cancer.
  • the agents that cause the most frequent neuropathy from among the chemotherapeutic agents are platin, taxan and vinca alkaloids. Particularly cisplatin and oxaliplatin that are some of the platin compounds lead to neuropathy.
  • the most frequently used chemotherapeutic agents in common cancers are oxaliplatin in colon cancers, cisplatin and taxan in lung cancer, again taxan in breast cancer.
  • Platin compounds may damage the nerves in particularly the hands and feet and especially the sensory nerves (“glove-sock type neuropathy”).
  • Oxaliplatin that is commonly used in colon cancers can especially cause sensory polyneuropathy (multiple nerve damage in especially hands and partially in feet).
  • Polyneuropathy that develops depending on oxaliplatin may intensify even more due to particularly being in contact with cold. Again taxan, and vinca alkaloids may also cause neuropathy to progress further.
  • Polyneuropathy related to taxan is in the form of sensory neuropathy that is especially notable in hands and feet, similar to polyneuropathy that may develop due to platin compounds. Nerve damage in the feet that are dependent on vinca alkaloids is typical.
  • the related chemotherapeutic agent can cause damage to the nerves that neighbor the veins via blood (especially in the hands and feet) when said agent is given intravascularly.
  • Chemotherapy can be applied at certain periods of time, as repeated doses. Chemotherapy graphs are available which show the efficient and safe doses, application routes, and the intervals at which and how chemotherapeutic agents can be applied for the cancer type, and the efficiencies of each chemotherapeutic regime has been proved by scientific studies. When repeated chemotherapy sessions are applied, the risk of neuropathy in the future is also increased, as expected.
  • CIPN peripheral neuropathy associated with chemotherapy
  • Transcutaneous Electrical Nerve Stimulation (TENS) devices are more commonly used in the field of physical therapy during daily practices.
  • the devices are used generally to provide symptomatic comfort for patients with conditions related to the muscles such as fibromyositis.
  • a Tens device has been used in order to reduce the side effects of peripheral neuropathy that is caused by chemotherapeutic agents constituting high neuropathy risks such as oxaliplatin and taxan, that are given to cancer patients that are receiving chemotherapy treatment.
  • a TENS device that has been designed to reduce pain and to reduce pins and needles due to peripheral neuropathy caused by chemotherapy treatments of the prior art, has been designed for domestic usage and its effect has been examined.
  • TENS devices that are used in treatment neuropathy after said neuropathy has developed in association with chemotherapy. It is a very difficult and tedious process to treat or completely eliminate the damage to the nerves after said damage has occurred. As a result, it is a necessity to design a device that prevents the development of neuropathy rather than treating it after it has developed.
  • the foremost aim of the invention is to increase regional blood circulation by stimulating the nerves in said region by transmitting electrical stimulation at certain frequencies at certain intervals by means of a TENS device that can be specially customized for each patient and that is placed inside a glove, which shall provide stimulation concurrently with the application of the chemotherapeutic agents (particularly taxan, platin etc.) to the patient, that have high risk of causing neuropathy and as a result, to prevent the development of neuropathy in a patient concurrently with the application of chemotherapeutic agents to the patient.
  • chemotherapeutic agents particularly taxan, platin etc.
  • the feeding and oxygenating the nerves can be increased by increasing the blood circulation in the region, by stimulating the nerves in said region.
  • the increased blood circulation as the transient passage of the chemotherapeutic agent within the vein that neighbors the nerves, that is in circulation at that moment shall also be accelerated, the risk of damage to the neighboring nerves by the chemotherapeutic agent shall also be reduced or even prevented.
  • oxaliplatin that is one of the platin compounds
  • intravascular infusion of the chemotherapeutic agent, presence of the agent within blood circulation may cause polyneuropathy that can be aggravated (increased) with cold, during the acute (early) stage.
  • paresthesia a sensory disorder such as pins and needles
  • an“electric shock” in hands and feet that may occur due to being subjected to cold temperatures. This can become more significant during chemotherapy and within the few days following chemotherapy. Due to this reason, it is advised for patients to keep away from the cold especially during these periods of time.
  • Another aim of the invention is to minimize both nerve damage by means of the tens device located inside the glove and also to minimize the risk of neuropathy which is the side effect of an agent used for cancer treatment by constantly tracking hand temperature (by means of the thermometer and resistance) and by keeping it constant a certain degree.
  • This device aims to provide electrical stimulation to the nerves and the resistance that has been placed inside glove increases the temperature up to 37 °C at the regions that carry neuropathy risk, and the resistance also keeps the temperature at a constant value and the thermometer inside the device tracks the temperature of the hands and in the event that there is a drop in temperature, the thermometer in the device subject to the invention, senses this drop of temperature immediately and temperature inside the glove is brought back to normal body temperatures (37 °C) by means of the resistance.
