Definitions

  • the invention relates to a field of medicine, namely, to a medical technology, and it is intended to infuse solutions to a human bloodstream in a medical practice, and it is for a disposable use.
  • Infusion is a slow infusion of a substance to a vein at a controlled or required rate; usually, this method is used to supplement for a lost body fluid and electrolytes, to administer blood products or to perform an extended administration of drug substances (e.g., antibiotics or pain medications etc.), as well as to feed a patient.
  • drug substances e.g., antibiotics or pain medications etc.
  • the infusion therapy means an intravenous administration of the infusion solutions to recover a deficiency of the blood circulation volume, to correct a water-electrolyte and an acid-base balance, and to administer drugs which could not be taken by the patient orally, or when only a parenteral administration route is possible.
  • Anti-bacterial, anti-viral, and anti-tumor chemotherapy when anti-bacterial, anti-viral or cytostatic drugs are administered, may serve as another example.
  • the infusion therapy utilizes an infusion device which is referred to as “an infusion system” in medical field, while its main purpose is to infuse blood substitutes and infusion solutions to the human blood stream.
  • an infusion system in medical field
  • the Applicant is aware of a large number of infusion devices, since the infusion therapy has been known for ages. Infusion devices have been continuously improving in the course of development and gaining knowledge by humanity.
  • the Applicant has revealed several technical solutions which are the closest ones to the proposed invention in terms of essential features.
  • a drawback of the proposed technical solution lies in that a needle to be introduced into a solution medium is made completely plastic, thereby leading to a formation of a large rupture in a bottle cap or in a package with the solution, and the drug may pour out of the bottle not through a dropper, but outside the dropper. Then, in order to fill the dropper with the solution from the bottle, it is required to move the dropper for several times, to tilt it, i.e., to adjust the filling of the dropper.
  • the needle is jointly made with the dropper, as made in the device according to the reference, if the required moves of the dropper are made, then the needle will be loosened in the bottle cap and this may lead to a leakage of the solution outwardly, not through the dropper.
  • the device does not comprise a separate filter for the solution after an additional port for administration of the solution, where its main function could have lied in holding air droplets and all microparticles which could enter the device during an additional infusion of other solutions by means of syringes and other means and deices, and the air during an additional administration of medicines or in case of any incorrect filling of the dropper.
  • This filter protects the patient’s blood stream, during performing infusions, from entering of any types of contaminations, particles, air droplets, which are possible during such manipulation.
