Definitions

  • the present invention relates to a system for aspirating fluids from a human or animal body by means of negative pressure according to the preamble of patent claim 1, a drainage pump unit according to the preamble of patent claim 11 and a method for operating such a system according to the preamble of claim 12.
  • Drainage pump systems are used for aspirating body fluids or fluids in the medical field, for example during thorax drainage or during wound drainage, but also during or after surgical interventions or during the aspiration of body fats.
  • These systems typically include a suction or vacuum pump, one or more fluid collection containers, and a drainage tube connection between the patient and the fluid collection container.
  • the fluid collection container may be connected to the pump via an external vacuum hose and a water lock, as for example in WO 03/103747 is disclosed. However, it may also be releasably attached to the housing of the drainage pump, as proposed for example in US 2009/0163882 and US 2009/0157019.
  • the vacuum line runs inside the pump housing. It is also known to guide a service line from the pump to the patient in addition to the drainage line.
  • a double-lumen tube is used, wherein a first lumen forms the drainage line and the second lumen is an air line which opens into the drainage line at the patient-side end.
  • this lumen can be used as a measuring line to determine flow or pressure differences.
  • a service line connected to the patient-side end of the drainage tube is also used to rinse the drainage line in order to avoid or eliminate occlusions of the line by sucked-in fluid lumps or tissue.
  • US 2011/0071415 also shows a drainage tube and a separate flushing line.
  • WO 2010/126444 and WO 2011/037524 relate to a wound drainage system with a flushing line and an additional pump. This second pump is used to draw air from the fluid collection reservoir through the purge line to the wound and from there through the drainage line back into the fluid collection reservoir.
  • the system according to the invention for aspirating fluids from a body by means of negative pressure comprises: a drainage line for discharging the fluid from the body, a fluid collecting container connected to the drainage line for collecting the extracted fluid, a pump for generating the negative pressure used for aspirating the fluid in the Drainage line and an auxiliary line whose proximal end is in fluid-communicating connection with a proximal end of the drainage line.
  • a closed or approximately closed circuit is present or can be generated in the system which connects this pump, the auxiliary line, the drainage line and the fluid collection container and through which air or a liquid can be pumped, wherein the auxiliary line can be used for flushing the drainage tube.
  • a two-way valve is provided in the system to form the closed or approximately closed circuit, the two-way valve having a first position in which the connection between the pump and the auxiliary line is broken, so that air sucked out by the pump is discharged into the environment and the circuit is open. In this position, a negative pressure is built up in the fluid collection container and in the drainage line and so the body fluid from the
  • the circuit is usually only approximately closed, because the drainage line terminates in a connecting piece, which has suction openings to the wound through which wound fluid can be sucked.
  • the drainage line and the auxiliary line terminate in a common catheter or other common fitting.
  • catheters and fittings are known in the art.
  • the drainage pump unit according to the invention for use in a system according to the invention has a suction pump for generating a negative pressure used for the suction of a fluid, which can be applied in a drainage line which can be connected to the drainage pump unit.
  • the Drainage pump unit is connectable to an auxiliary line whose proximal end is in fluidkommunipreparingder connection with a proximal end of the drainage line.
  • the drainage pump unit further comprises a two-way valve, the two-way valve serving in a first position for venting the suction pump in the environment and in a second position for connecting the suction pump with the auxiliary line. In this second position of the two-way valve, the auxiliary line for flushing the drainage tube is used.
  • This drainage pump unit may comprise the suction pump and its control. Preferably, it also comprises one or more fluid collection containers, which can be fastened to the housing of the suction pump. Preferably, this drainage pump unit is designed as a portable device.
  • a connection is created between the pump and the auxiliary line, through which air flows from the pump through the auxiliary line.
  • an approximately closed circuit is created, which connects this pump, the auxiliary line, the drainage line and the fluid collection container with each other, which air is pumped through the drainage line into the fluid collection container, whereby the drainage line is cleaned.
  • a liquid may also be pumped from the pump through the auxiliary line to clean the drainage line.
  • a salt solution is suitable.
  • Air which the vacuum pump discharges into the environment when the circuit is open is now pumped into the auxiliary line.
  • the speed of the pump controls the speed (intensity) of the air flow without affecting the pressure level. No external air is used for the flushing. This is particularly desirable in a hospital environment because the risk of introducing external germs into the wound is minimized. However, it is also possible to pump a liquid through the auxiliary line to the drainage line instead of air so as to purify the system. It is a further object of the invention to provide a system and method by which pressure in the region of the body cavity can be measured.
  • a pressure sensor it is easy to determine the pressure in the area of the wound or another body cavity.
  • the drainage line is first rinsed as described above and then the pressure in the drainage line and thus also in the cavity of the body is measured when the pump is switched off.
  • the pressure sensor can be arranged on the container-side outlet of the pump, between fluid collection container and pump, in the fluid collection container or in the drainage line.
  • the sensor is arranged between the pump and the fluid collection container. It is thus not necessary to arrange a sensor near the wound or in the area of the auxiliary line. It is possible to use the same pressure sensor, which also monitors the operation of the pump during the drainage process.
  • a blockage can be easily recognized. If the pressure at the pressure sensor rises when flushing, the closed circuit is not free and a blockage must be rectified.
  • the flushing and also preferably the pressure measurement is automatic and repetitive.
  • the appropriate control of the two-way valve can be done via the control of the pump. It is also advantageous that only one valve must be actuated and not further pumps or other components are involved. This simplification reduces development and manufacturing costs, increases the reliability in use and reduces any maintenance work.
  • the system according to the invention thus successfully removes secretion blockages from the tube system, offers active prevention of blockages, detects existing blockages and makes possible a relatively accurate pressure measurement in the region of the body cavity or the wound.
