Definitions

• the invention relates to the field of medical devices, in particular blood treatment devices such as dialysis machines and their operation.
• Blood treatment devices are medical devices in which the blood of a patient is usually treated extracorporeally. For example, drugs may be added to the blood or blood components removed from it, it may be heated or cooled. These processes are often monitored by sensors. Blood treatment devices have a variety of means for these purposes, such as pumps, valves, sensors, clamps or the like. Furthermore, medical disposables are often used for blood treatment. Such disposable articles are usually discarded after treatment for reasons of hygiene. Medical disposables, or so-called disposables, are, for example, tubing sets for administering medical fluids such as blood or medicaments, filters, such as adsorber filters or dialysis filters, sachets for storing medicaments, and the like.
• Dialysis machines are blood treatment devices in which a fluid from a patient is supplied via a fluid line to a fluid treatment component, treated by the fluid treatment component, and returned to the patient via the fluid line that can be divided into an arterial and a venous branch.
• blood treatment devices are in particular hemodialysis machines.
• Such a blood treatment device is the subject of DE 198 49 787 Cl the applicant, the content of which is hereby incorporated in full in the disclosure of the present application.
• Dialysis is a procedure for purifying the blood of patients with acute or chronic renal insufficiency. Basically, a distinction is made here between methods with an extracorporeal blood circulation, such as hemodialysis, hemofiltration or hemodiafiltration and peritoneal dialysis, which has no extracorporeal blood circulation.
• the blood is passed in hemodialysis in an extracorporeal circuit through the blood chamber of a dialyzer, which is separated by a semipermeable membrane of a dialysis fluid chamber.
• the dialysis fluid chamber is flowed through by a dialysis fluid containing the blood electrolytes in a specific concentration.
• the substance concentration of the blood electrolytes in the dialysis fluid corresponds to the concentration in the blood of a healthy person.
• the patient's blood and the dialysis fluid on both sides of the semipermeable membrane are generally passed countercurrently at a predetermined flow rate.
• the urinary substances diffuse through the membrane from the blood chamber into the dialysis fluid chamber, while at the same time electrolytes present in the blood and in the dialysis fluid diffuse from the chamber of higher concentration to the chamber of lower concentration. If a pressure gradient from the blood side to the dialysate side is established on the dialysis membrane, for example by a pump which removes dialysate from the dialysate circuit downstream of the dialysis filter on the dialysate side, water passes from the patient's blood via the dialysis membrane into the dialysate circuit. This process of ultrafiltration leads to a desired drainage of the patient's blood.
• ultrafiltrate is withdrawn from the patient's blood by applying a transmembrane pressure in the dialyzer, without dialysis fluid being conducted past the side of the membrane of the dialyzer opposite the patient's blood.
• a sterile and pyrogen-free substituate solution can be added to the patient's blood.
• this Substituatswishing is added upstream of the dialyzer or downstream, it is called pre- or post-dilution.
• the mass transfer occurs convectively during hemofiltration.
• Hemodiafiltration combines the methods of hemodialysis and hemofiltration. There is both a diffusive mass transfer between the patient's blood and dialysis fluid via the semipermeable membrane of a dialyzer, as well as a filtration of plasma water by a pressure gradient at the membrane of the dialyzer.
• Plasmapheresis is a blood treatment procedure in which the patient's blood is separated into the blood plasma and its corpuscular components (cells). The separated blood plasma is purified or replaced with a substitution solution, and the purified blood plasma or the substitution solution is returned to the patient.
• peritoneal dialysis In peritoneal dialysis, the abdominal cavity of a patient is filled via a guided through the abdominal wall catheter with a dialysis fluid, which has a concentration gradient with respect to the body's own fluids. Via the peritoneum acting as a membrane, the toxins present in the body pass into the abdominal cavity. After a few hours, the now spent dialysis fluid in the abdominal cavity of the patient is exchanged. Osmotic processes allow water from the patient's blood to pass through the peritoneum into the dialysis fluid and drain the patient.
• the method for peritoneal dialysis is usually carried out with the aid of automatic peritoneal dialysis machines, such as those marketed by the applicant under the name sleep.safe.
• Dialysis machines as an example of complex medical fluid management devices, have extensive functions. To control these functions, medical fluid management devices such as dialysis machines are equipped with at least one control device. These can be implemented as CPU (central processing unit) or microcontroller, which are programmed by software programs. The operation of such devices is often done via touchscreen displays. Such a touchscreen display combines in a common surface an input and an output device in which it provides a touch-sensitive surface with which operator inputs are detectable.
• CPU central processing unit
• microcontroller microcontroller
• information such as operating instructions or messages can be output, which are assigned to certain parts of the dialysis machine. This may occur, in particular, when upgrading the device with accessories prior to treatment, as well as after a successful treatment, when these accessories are disassembled.
• text hints can be displayed, which give instructions that may be supplemented by pictures, in particular pictograms, which represent the relevant action or parts of the dialysis machine on which certain actions are to be performed.
• text messages or images can be displayed, which are directed to certain parts of the dialysis machine or represent, for example, in case of malfunction of certain parts that can be detected by appropriate sensors.
• the operator Since the display device and the relevant parts of the dialysis machine are arranged spatially separated from each other, the operator must first locate the relevant part of the dialysis machine, if necessary. This can be especially inexperienced Operators take valuable time, or in the case of ambiguous representations on the display device lead to incorrect operation.

• OLED displays are known in the art mainly as a display device of small portable devices, such as mobile phones or digital cameras. Such displays are in contrast to LCD display self-luminous displays.
• An organic light-emitting diode is similar to a silicon-based light emitting diode of two layers, consisting of a p-doped and an n-doped semiconductor material constructed. At the contact surface of the two semiconductor layers, a pn junction is formed in which energy is released in the form of light radiation as a result of a current flow through the pn junction during the recombination of electrons with atoms which lack an electron (so-called holes).

Likewise, alternatively or additionally any texts or graphics can be displayed, for example measured values or device settings as examples of operating parameters of the medical device. Further information that may be displayed may include operating instructions for the medical device or messages concerning the medical device, or refer to a treatment performed with the medical device.
• Another aspect of the invention relates to the combination of a transparent display with a device that controllably removes or reduces this transparency.
• a device for reducing the transparency may be, for example, a liquid crystal cell, which changes its optical state from transparent to opaque by applying a voltage.
• US 2009/0015740 Al describes such a system for darkening a glass window.
