Definitions

  • the invention relates to an elastomeric pump for the delivery of medications to a patient, comprising a reservoir, an inflatable balloon with a first end and a second end and defining an interior space, a valve, an anchoring zone next to said valve, said first end being mounted on said anchor zone, and said anchor zone defining a communication passage between said valve, said interior space of said inflatable balloon and an exit orifice, and fluid connection means between said balloon and said patient, wherein said reservoir has a hollow rod that extends into said reservoir.
  • Elastomeric pumps of the type indicated above are known. Certain diseases require the supply of medications on an ongoing basis for long periods of time (such as chemotherapy treatments, painkiller supplies, etc.). In these cases, the use of elastomeric pumps allows the patient to be given a high degree of mobility and independence, which may even allow him to remain at home while receiving the treatment.
  • the balloon is made of an elastomeric material in which the medicine is pressed under pressure. In some cases these balls can break or tear, with the consequent spillage of the medicine. Frequently these medications are very aggressive, so it is very important to avoid coming into contact with the skin of the patient and / or health personnel.
  • the ball is inside a tank, so that the medicine would remain inside the tank in the event of the ball breaking.
  • this deposit cannot be airtight, since during the delivery of the medication to the patient the balloon is deflated, and a depression would be generated inside the tank that would adversely affect the flow of medication being supplied. Therefore it is known to include in these tanks a membrane or filter that allows the passage of air but not of liquids.
  • these filters can never get wet, since once they are wet they are no longer permeable to air. This forces the patient to take extreme precautions to prevent the filter from getting wet.
  • the balloon is an elongated tube of elastomeric material that is fixed by each of its ends in a cylindrical projection present in the corresponding anchoring zone. Fixing is frequently done by means of a flange that presses the end of the tube against the cylindrical projection. This form of fixing is economical and allows sufficient sealing. However, a concentration of tensions is generated in the area of the tube next to the joint, which increases the amount of tears or tears of balls.
  • This improved design should reduce the risk that the skin of the patient and / or health personnel come into massive contact with the medicine in case of balloon rupture. Therefore the improved design should correct both the problem of possible exit of all the medication out of the tank, and / or reduce the risk of balloon ruptures.
  • an elastomeric pump of the type indicated at the beginning characterized in that: [a] it additionally comprises a cover, which is positioned on said rod, [b] said rod extends to approximately a central point of said tank, [ c] through said rod the passage of air between said reservoir and the outside is possible, and [d] said second end of the inflatable balloon is mounted on said cap.
  • the ends of the ball at two fixed points of the tank.
  • the medication when the medication is injected into the balloon, it deforms only transversely.
  • the balloon is deformed both transversely and longitudinally during the injection of the medication and, correspondingly, during the delivery of the medication.
  • the lid is suitable for sliding along the rod.
  • an air filter is housed inside the rod, which allows the passage of air while preventing the passage of liquids. This type of filters is known and, as already indicated above, it should be avoided that they get wet, since they cease to be permeable to air. Its accommodation inside the rod is particularly interesting, since it is extremely protected, which prevents it from accidentally getting wet.
  • the inflatable balloon is preferably an elongated tube, and advantageously has an annular flange at least one of its ends.
  • the annular flange allows reducing and / or compensating the effect produced by the concentration of stresses in the area near the flange, thereby reducing the risk of breakage or tearing.
  • fluid connection means extend that on one side are connected to the inside of the balloon, and, on the other hand, are connected to the patient's body, usually to some blood vessel of the patient.
  • These fluid connection means can be diverse, and contain various elements.
  • they comprise a first tube, connected to said outlet orifice, a particulate / air filter, connected to said first tube, and a connector.
  • the connector is standard and can be connected to any usual element, such as cannulas, catheters, needles, etc.
  • a flow regulator and a second tube are preferably added, connected to said particle / air filter and said flow regulator.
  • the flow regulator out of the tank allows direct contact with the patient's skin, allowing it to be kept at a much more constant temperature. In this way, the flow rate, which depends, among other things, on the viscosity of the medicine and, therefore, on the temperature, is regulated in a more stable way.
  • the purpose of the capillary tube is not to regulate the flow rate (function played by the flow regulator) but simply to physically separate the flow regulator from the connector.
  • the element that is partially inserted into the patient's blood vessel is less bulky, and the flow regulator is attached to the cnector via the capillary tube, which is flexible, and can be attached to the patient's skin at a point. close to the connector, but attached to it in a flexible way, which improves patient comfort.

In this case, flange 57 is totally conventional and consists substantially of a head 63 with a hole and a serrated tail 65. The free end of tail 65 is introduced in the hole, in which there is an internal projection that allows the introduction of the tail 65 in a single direction, so that once the tail 65 is introduced it is no longer possible to extract it again.

  • the inflatable balloon 3 has a central part 71 whose inner surface is also frustoconical.

  • Another advantage of the elastomeric pump according to the invention is that it is possible to manufacture elastomeric pumps of different nominal capacities while retaining most of the elements that form it. That is, only by changing some element can a pump of different capacity be obtained. This has obvious advantages of a productive and logistic type, by reducing the amount of different elements that must be manufactured.
