Definitions

  • the invention relates to: a device for treating, in particular for rinsing bones, wounds, the abdominal cavity or the like parts of the human or animal body with aseptic liquid according to the preamble of claim 1.
  • the pump can be coupled to a compressed air drilling machine for driving by adapter means.
  • Compressed air drills of this type are in any case present in every operating room, so that at least the drive of the pump can be ensured by means of an already existing device which works without an electric motor.
  • such a pump can be regulated very well, i.e. the liquid flow can be adapted exactly to the requirements, which is very difficult with a peristaltic pump.
  • the pump is a gear pump to which the spray tube or the snorkel can be connected directly.
  • the gear pump is designed for the pulsating delivery of liquid. This pulsating delivery substantially reduces the amount of liquid required for cleaning, since the individual pulses ("splashes") have a substantially large bring with it a cleaning effect than the continuous stream. If you compare this solution to the problem with the known device, which has a peristaltic pump, the peristaltic pump itself also delivers in a pulsating manner, but the pulsating delivery flow is initially reduced by a long one
  • Hose piece passed which forms a spring element due to its elasticity, so that a mass-spring system is created.
  • This mass-spring system now has a "low-pass characteristic", ie the rapid pressure increases are smoothed out.
  • the arrangement according to the invention ensures that the pressure pulses generated by the gear pump reach the flushing pipe unfiltered, that is to say in full sharpness.
  • the pump is preferably mounted directly on and driven by a compressed air drilling machine, so that a handy, compact device is produced, which is particularly important for use in the operating room.
  • Gear pumps in themselves are those displacement machines which (in addition to screw pumps) have the lowest degree of non-uniformity in the delivery flow.
  • the present invention takes a completely different route, which consists in designing a gear pump in such a way that a particularly strongly pulsating delivery flow is produced. This can be solved in various ways.
  • a gear pump with as few teeth as possible, in extreme cases a capsule pump (two teeth), is used so that the delivery flow pulsates strongly.
  • the pulsation is achieved in that the sealing gap between the two gear wheels is opened again and again by means of recesses in at least one of the two gear wheels, so that a "short circuit" between the inlet and outlet arises. During this short circuit, therefore, no pressure medium is delivered, so that when the recess passes the sealing gap between the two gear wheels, the pressure increases again abruptly.
  • a (rotary) slide is provided which rotates with one of the gearwheels and opens and closes the pressure outlet of the pump directly.
  • the pressure increase is particularly strong, so that the necessary flow rate or the amount of liquid required to clean a certain surface is minimal.
  • the rinsing liquid is preferably stored in a cartridge which can be coupled directly to the pump mounted on a compressed air drilling machine via suitable adapter means (bayonet closure).
  • suitable adapter means bayonet closure.
  • a feed hose possibly via the same connection means to the pump

Abstract

Un dispositif sert à traiter, notamment à rincer avec un liquide aseptique, des os, des plaies, la cavité abdominale ou des parties similaires du corps humain ou du corps d'animaux. A cet effet, une pompe (10) entraînée par rotation envoie le fluide sous pression et par impulsions à travers un tuyau de rinçage (27) ou un tuba jusqu'à l'emplacement à traiter. La pompe (10) peut être couplée (1) à des fins d'entraînement à une perceuse à air comprimé, au moyen d'un adaptateur (30), ce qui en fait un appareil très commode d'emploi.
