Definitions

  • the present invention relates to a device for hemostasis at a puncture site of a fistula.
  • Patients who have undergone dialysis treatment must have the puncture site, i.e. Press the puncture site of the needles of the extracorporeal blood circuit to stop the bleeding for a longer period of up to 40 minutes.
  • the needles are in a fistula, i.e. inserted into an artificially created vessel of the patient in order to remove blood to be purified from the patient's bloodstream and to e.g. return purified blood to the patient's bloodstream using a dialyzer.
  • the need to press the puncture site over a longer period of time in order to stop the bleeding is associated with the disadvantages that the patient has to remain on site for a comparatively long time and occupies the treatment place, although the actual treatment has already ended that the patient is in his freedom of movement is restricted, since he has to push the puncture site with one hand, that the staff due to the long length of stay of the patient is also bound accordingly long and that the puncture site is not pressed in a defined manner.
  • the latter can lead to the pressure on the fistula possibly being too high, which can damage the pressure-sensitive fistula and thus shorten the life of the fistula. This in turn affects patient safety. Too much pressure can damage the fistula and possibly prevent blood flow; too little pressure may not be sufficient to stop the bleeding.
  • DE 10 2015 010 743 A1 discloses a cuff for stopping the bleeding at a puncture site of a patient with a control, by means of which a profile for controlled insertion into the chamber of the cuff can be realized.
  • US 2013/0085524 A1 discloses an inflatable compression means for a leg vessel.
  • US 2002/0016610 A1 shows a controller for a trigger tape, the pressure in the tape being increased as soon as blood flow is detected.
  • a device is known from US 2015/0201948 A1 by means of which pressure can be exerted on an artery.
  • the present invention has for its object to provide a device by means of which the bleeding can be reliably stopped at at least one puncture site of a fistula.
  • the device has a cuff with one or more fluid-filled or fillable chambers, at least one of which is designed to be arranged on the puncture site, and wherein the device has a sensor system that is designed to determine the state of the Monitor the fistula and / or the puncture site.
  • the cuff contains at least one chamber, which is preferably inflatable. The cuff is placed around the patient's arm.
  • the fluid is preferably air.
  • the chamber includes one or more separate volumes that can be placed on the puncture site and that, when filled, apply pressure to the puncture site to stop bleeding from the puncture site.
  • the sensor system of the device serves to detect the condition of the fistula and / or of its puncture site. It is thus possible to regulate the pressure in the at least one chamber as a function of one or more parameters, in particular as a function of values that were recorded by means of the sensor system.
  • the sensor system is preferably integrated in the cuff.
  • a pressure control device which regulates the pressure in the or the chambers of the cuff to a certain target value or ⁇ in a certain setpoint range.
  • This pressure control device can comprise, for example, a piezo or solenoid valve and adjust or regulate the pressure in the chamber to a patient-specific pressure value. In this case, it does not matter how tightly the cuff is applied and whether the patient is exerting pressure on the chamber, such as by wearing tight clothing or by accidentally propping the cuff.
  • the pressure control device is designed to regulate the pressure in the chamber or chambers of the cuff as a function of one or more parameters, which are preferably parameters or their values that are generated by the sensor system of the device were recorded. For example, it is conceivable that the sensor system speed sensor and that when a blood leak is detected, the pressure in the chamber is increased.
  • the patient-specific pressure is first set and that when a condition to be corrected is detected by means of the sensor system, this patient-specific regulation is superimposed by a regulation that corrects the pressure as a function of the detected one State regulates, for example to close a leak.
  • a pressure sensor is preferably present, which detects the pressure in the chamber or chambers of the cuff.
  • This pressure sensor can be used to supply the actual value of the pressure for a pressure control and / or to set a specific pressure profile. For example, it is conceivable for the pressure in the chamber to drop continuously or discontinuously towards the end of the pressure-off time, patient-specific control or regulation being possible.
  • the pressure sensor can be attached to the chamber.
  • the sleeve can be designed in the form of a band and have an elongated, band-shaped base body, on or in which the at least one chamber is arranged.

  • the ribs, pads, etc. preferably rest on the forearm bones when the cuff is put on.
  • ribs, pads, etc. can also be arranged on the outside of the cuff.
  • the ribs, pads or other reinforcement parts can serve as stiffening in order to give the cuff a certain shape and / or strength.
  • these can alternatively or additionally be arranged on the inside.
  • the ribs, cushions or reinforcing parts are patient-specific and / or are designed such that the rigidity e.g. is adjustable via a pressure sensor to prevent the cuff from fitting too tightly.
  • the ribs, upholstery or reinforcement parts etc. which are arranged on the outside and / or on the inside of the cuff, can be fluid-filled and preferably air-filled.
  • ribs, upholstery encompass any element that has a fluid-filled or fillable interior and / or that serves as a reinforcing element of the cuff, regardless of the shape, length, arrangement on the Cuff, number etc.

  • This embodiment is particularly useful for a disposable item.
  • stiffening elements in particular stiffening ribs, which are preferably located on the outside of the sleeve.
  • the material of the stiffening elements is preferably firm and has such a great mechanical stability that the cuff fits correctly and the chamber can exert its effect, which consists in exerting pressure on the puncture site in the patient's skin when the cuff is in place.
  • the outside of the chamber consists of a harder and / or less elastic material than the inside of the chamber.
  • the outside is the part facing away from the patient's skin and the inside is the part of the cuff facing the skin when it is put on.
  • This design has the advantage that the expansion of the chamber can be influenced in a certain direction. It is conceivable if the outside of the chamber is made of injection molding and / or polycarbonate and the inside is made of a soft or elastic material, such as a film (e.g. PVC) or has these materials.

In this case, it is conceivable that there is a sterile pad on the inside of the entire cuff or on a part thereof, such as on the chamber, which can be torn off or otherwise removed after use. It is conceivable that, comparable to a block, there are a plurality of sterile overlays one above the other, from which the respectively used one is removed, at the same time the unused pad is exposed so that the cuff can be used again immediately.
  • the device has at least one check valve, which is arranged to prevent the backflow of fluid from the chamber. It is also conceivable that there are several ribs, cushions, etc., each of which is assigned a check valve.

  • the fluid supply has a valve, by means of which the supply and / or the discharge of fluid into or out of the chamber can be prevented or released.
  • the air supply valve can be installed directly on the chamber. However, it is advantageous if the valve is integrated in the sleeve and is connected to the chamber via a (thin) hose.
