Definitions

  • the invention relates to a device with a fluid pump, at least two abdominal wall access and fluid pump and abdominal wall connecting hoses.
  • Such devices are known, for example, as peritoneal dialysis systems.
  • Peritoneal dialysis is used for intracorporeal blood purification.
  • peritoneal dialysis a volume of approximately 1 to 3 liters of dialysate, which consists of an electrolyte solution, is administered into the peritoneal cavity to detoxify the blood.
  • dialysate which consists of an electrolyte solution
  • the removal of the harmful substances from the organism thus takes place by a drainage of the dialysate to the outside.
  • Peritoneal dialysis is used in renal insufficiency and can be performed independently of a dialysis center.
  • a peritoneal dialysis catheter made of silicone is usually used.
  • the invention is based on the object of designing such a device such that it can also be used for other medical fields of use. [05] This object is achieved with a generic device having a C0 2 removal device having fluid communication with the fluid pump and the abdominal wall accesses to remove from a fluid C0 2 .
  • the device known from dialysis can thus also be used for C0 2 removal. While the known device supports the kidney, the new device supports the lung. Thus, according to the invention, a device known from the field of blood purification is modified such that it can be used for gas exchange with respect to the blood.
  • the device has a tempering device which has a fluid connection with the fluid pump and the C0 2 Entferaungs announced.
  • a temperature control device which heats or cools a liquid or gas stream flowing into the abdominal cavity, can be used as a single device in the flow of fluid or as a combination device in conjunction with the fluid pump or the C0 2 removal device.
  • the tubes are tempered. Temperable tubes can thus cool or heat the fluid and thereby offer the treating physician a wide range of exposure to a human or animal body.
  • a measuring device for determining the fluid composition is proposed.
  • This measuring device can also be connected to a control device in order to regulate the fluid composition.
  • the temperature of the fluid is regulated with the measuring device.
  • gases such as C0 2 or 0 2 measured in the fluid or the proportion of electrolytes, buffer substances, etc. and optionally also regulated.
  • the fluid can be a gas or a vapor that passes through the abdominal cavity. Depending on the application, different gas or vapor compositions are suitable, with humidified gases preferably being used.
  • the fluid is a liquid.
  • Such a fluid is particularly suitable for C0 2 removal, as it provides gas in the area of the abdominal cavity from the blood into the fluid, for example, to remove C0 2 from the blood.
  • the device has a control for the pump. This makes it possible to provide either a very constant flow of fluid or else a pulsating flow which correlates with the diaphragm movements or which improves the gas transfer by means of a pressure modulation.
  • C0 2 -binding substances such as perfluorocarbons.
  • C0 2 -binding substances such as perfluorocarbons.
  • C0 2 -bindende substances There are various medically usable C0 2 -bindende substances known, which can be introduced depending on the purpose in the fluid to intensify the C0 2 removal.
  • the C0 2 removal device is an oxygenator.
  • C0 2 removal device can serve a Membranlunge or a membrane fan.
  • bubble oxygenators and membrane oxygenators are also very suitable.
  • membrane oxygenators can be used differently than is usual when they pass through two liquids or gas and liquid in order to transfer C0 2 from one liquid to another.
  • the C0 2 removal device has an oxygen enrichment device.
  • Such an oxygenating device may operate either via ambient air, oxygen-enriched gases or nearly pure oxygen.
  • the abdominal wall accesses are implantable, closable passages. This allows the patient to repeatedly use these abdominal wall accesses to treat his blood.
  • abdominal wall accesses permanently elastic, biocompatible spouts for superficial sewing or gluing are.
  • abdominal wall access tubes have hoses with lateral openings.
  • a particularly advantageous variant embodiment of an abdominal wall access provides that at least two abdominal wall accesses are designed in such a way that they can be arranged in a ventral abdominal passageway. This makes it possible, for example, to guide the inflow and the outflow via an abdominal wall access, inflow and outflow preferably being arranged radially one inside the other.
  • inflow and outflow preferably being arranged radially one inside the other.
  • pumps can be controlled as pressure and suction pumps so that the pressure of the fluid on the boundary of the abdominal cavity a maximum Value does not exceed.
  • the object underlying the invention is also achieved with a method for operating such a device, in which a fluid is passed through the fluid pump, the abdominal cover accesses and a C0 2 removal device in order to remove from a fluid C0 2 ,
  • the abdominal cavity can first be filled with fluid and then emptied.
  • the fluid is continuously supplied and removed through the abdominal wall access.
  • the flow parameters can be varied to achieve, for example, a pulsatile flow.
  • the object underlying the invention is achieved with a method for the use of abdominal wall accesses in which a fluid is pumped through the abdominal wall access and the fluid is passed through a CC removal device.
  • abdominal wall accesses 3 In the abdominal cavity 1 of a patient 2, two permanently elastic, biocompatible spouts 3, 4 are sewn in superficially as abdominal wall access. These abdominal wall accesses are designed as peritoneal dialysis catheters and make it possible to fill a fluid 5 via the access 3 into the abdominal area 1 of the patient 2 and to remove it again from the abdominal area 1 via the access 4. This liquid is passed through a measuring device 6 for determining the fluid composition and then a C0 2 removal device 7 forwarded. From there, the liquid 5 passes to a fluid pump 8 and then via a tempering device 9 to the abdominal wall access 3, through which the liquid passes back into the abdominal cavity.
  • the liquid is passed through lines 10, 1 1 (numbered only by way of example), which can also be designed to be heated.
  • the tempering device 9 and the hose heating can also be used for fluid cooling.
  • a pump control 12 is provided, which not only can turn on and off the pump, but can also vary the pumped volume and can also vary in time the amount pumped.
  • the described simple construction allows an application for oxygenation of the blood of a patient with simultaneous C0 2 removal and temperature control of the blood through the abdomen.
