[0062] When it is stated here that an opening is "open vertically upwards", this can be the case if one can look into the opening from a vertical perspective above.

[0063] When this text refers to an opening that is vertically open upwards, this preferably means that the opening plane or a section thereof is arranged such that fluid can fall through the opening into the flushing port or fluid line from above in free fall. An opening into which only horizontally moving masses can enter, i.e., which necessarily require horizontal movement or velocity to enter the opening, is not considered to be vertically open upwards.

[0064] In some designs, the receptacle for receiving the section can be located, for example, on the machine front of the treatment device or on an outer housing surface of the treatment device. Fresenius Medical Gare Deutschland GmbH

[0065] In some versions, the receiver may be designed in the form of a holder or may have one.

[0066] In some designs, the receptacle can be integrated into or connected to the flushing port. For example, the receptacle can be part of the flushing port and designed to at least partially accommodate a flushing port connector by creating a detachable connection, such as a form-fit or force-fit connection.

[0067] In some designs, the flushing port consists of the fluid line, which is assigned to the interior of the treatment device, and the opening.

[0068] In some designs, the opening can limit the flushing port or fluid line, or at least a section of the flushing port or fluid line, at the top.

[0069] In some versions of the treatment device, it has a lid, for example a hinged lid, for closing or sealing the opening.

[0070] In some versions, the lid has a sealant, preferably a sealing ring.

[0071] In some embodiments, the treatment device further includes a drive mechanism for opening or closing the lid. The drive mechanism preferably comprises an electric motor.

[0072] The control device can be configured in these versions to control the drive mechanism. Fresenius Medical Gare Deutschland GmbH

[0073] In some versions of the treatment device, a pump is arranged in or on the fluid line inside the treatment device to draw fluid out of the rinsing port and into the fluid line.

[0074] In some versions, at least one sensor is provided to determine the fluid level or flow rate in the flushing port or fluid line. For this purpose, the sensor may be in signal communication with the control device or be prepared for this purpose.

[0075] In some versions, the control device is configured to prompt the pump to draw fluid from the flushing port and into the fluid line in response to a signal from the sensor.

[0076] In some embodiments, the receptacle is arranged such that an open end of the rinsing port connector of the extracorporeal blood tubing set or of another section of the extracorporeal blood tubing set is or is received at a predetermined distance from the opening.

[0077] In some implementations, the predetermined distance can correspond to the distance of the free fall or denote its length.

[0078] The predetermined distance or free fall distance can, in some embodiments, be between 2 cm and 5 cm; preferably it is 2 cm or at least 1.8 cm. Fresenius Medical Gare Deutschland GmbH

[0079] In some embodiments, the treatment device has an extracorporeal blood tubing set, and the rinsing port connector or other section of the extracorporeal blood tubing set is or is positioned at a predetermined distance from the opening of the rinsing port or fluid line.

[0080] In some implementations, the predetermined distance can be a structural gap or interruption. It can correspond to a distance for the free fall of the fluid.

[0081] In some embodiments, the receptacle is arranged such that an open end of the rinsing port connector of the extracorporeal blood tubing set or of the other section of the extracorporeal blood tubing set is or is received above or vertically above the opening when using the treatment device.

[0082] In some embodiments, the flushing port connector or the other section can be a connecting section in or by means of which the arterial line and the venous line are connected, directly or indirectly, preferably by fluid, preferably detachably.

[0083] In some designs, the irrigation port connector or the other section of the extracorporeal blood tubing set can be in fluid communication with the arterial and venous lines and may additionally have an opening for fluid to escape from the inside of the irrigation port connector or from the inside of the other section to its respective exterior. Fresenius Medical Germany GmbH

[0084] In some versions, the flushing port connector or the other section (e.g. designed as a "Y" or "T" or "L" piece) may be a disposable and / or an injection-molded part.

[0085] In some versions, the receptacle is designed to accommodate a "Y"-, "T"- or "L"-shaped section of the flushing port connector or the other section of the extracorporeal blood tubing set.

[0086] In some versions of the treatment device, the receptacle is located on one of the outer sides of the treatment device.

[0087] In some designs, the receptacle can be integrated into or connected to the flushing port.

[0088] In some designs, the receptacle is part of the flushing port and is designed in such a way that a flushing port connector can be at least partially received, or is already received, by creating a detachable connection. The detachable connection can be positive-locking or force-locking.

[0089] In some embodiments, the treatment device has a cover that can be moved from a first, preferably closed, position to a second, preferably open, position. The cover can face the outside of the treatment device and be attached to it, for example, to its machine front or its housing.

[0090] Preferably, the cover in these embodiments is attached in such a way that the cover in its first Fresenius Medical Gare Deutschland GmbH

[0091] In the first position, the cover covers both the opening of the flushing port or fluid line and the receptacle for the flushing port connector of the extracorporeal blood tubing set or the other section of the extracorporeal blood tubing set to the side and / or front. Preferably, this is not the case in the second position of the cover.

[0092] In some embodiments, the treatment device is equipped with an extracorporeal blood tubing set, with an open end of the flushing port connector of the extracorporeal blood tubing set or of the other section of the extracorporeal blood tubing set being arranged vertically above the opening.

[0093] In some designs, the flushing port and flushing port connector are dimensioned and / or connected to each other in such a way that the outer surface or the circumference of the free end, e.g. in the area of ​​the outflow opening thereof, e.g. along the distal or terminal 0.5 to 1.5 cm thereof, does not come into contact with a section of the flushing port connector, such as its inner wall, e.g., physically.

[0094] In some designs, the flushing port has a cross-sectional area that is larger than the cross-sectional area of ​​the opening and / or larger than the cross-sectional area or the area circumscribed by the circumference of the free end of the flushing port connector.

[0095] In some designs, the fluid line associated with the interior of the treatment device may have a filter, e.g., on the fluid path between the opening and the drain. Fresenius Medical Gare Deutschland GmbH

[0096] This filter can be used in particular to reduce or completely retain contaminants that could, for example, enter the treatment device via the (open) rinsing port.

[0097] In some versions, the control device is configured to prevent or allow negative pressure to be applied in the extracorporeal blood tubing set when the opening is open, for example, when the lid of the opening is open and / or when a flushing port connector or another section is inserted into the receptacle.

[0098] A build-up of negative pressure intended in other operating states would be excluded, blocked, prohibited, or the like in these implementation forms.

[0099] In some versions, the treatment device is known as a blood treatment device, in particular as a dialysis device, hemodialysis device, hemofiltration device or

[0100] Hemodiafiltration device, especially designed as a device for acute, chronic or continuous kidney replacement therapy (CKRT).

[0101] In some versions, the extracorporeal blood tubing set is used for treatment by means of a blood treatment device, in particular by means of a dialysis device, hemodialysis device, hemofiltration device or

[0102] Hemodiafiltration device, in particular by means of Fresenius Medical Gare Deutschland GmbH

[0103] a device designed for acute, chronic or continuous renal replacement therapy (CRT).

[0104] In some versions of the extracorporeal blood tubing set, the outlet of the chamber is connected to a flushing port connector in order to connect the extracorporeal blood tubing set to a flushing port of a treatment device in fluid connection.

[0105] In some embodiments, the cross-sectional area of ​​the interior of the chamber is larger than the combined cross-sectional areas of the second end of the arterial conduit, or the receptacle for it, and the second end of the venous conduit, or the receptacle for it.

[0106] Where procedural steps are mentioned herein, some versions provide that these take place before or after treatment of the patient, for example while the patient is not connected to the device, e.g. by means of an extracorporeal blood tubing set or the like, or while treatment has not yet started or has already ended.

[0107] In some embodiments, the control device is located in or on the treatment device, for example together with other components or devices of the treatment device in a common housing of the treatment device.

[0108] Where "automated" or "automatic" steps are mentioned herein, this preferably includes the fact that a correspondingly programmed control device, or a largely operator-free system, performs those steps. Fresenius Medical Gare Deutschland GmbH

[0109] An automatically initiated step is one that can be executed autonomously, i.e., without human intervention, without human input, and / or without a specific contribution from a human to the execution of the process. The initiation and thus ultimately the execution of these steps occurs through self-control and / or self-regulation of the control device or system, or is initiated by it, i.e., without operator influence that would or could affect the process or any of its results. An automatically initiated step can therefore be one that is triggered or initiated by the control device, particularly because it recognizes (e.g., based on sensor signals, upon reaching a program section, upon reaching a predetermined time, because a previous step has been completed, etc.) that the step in question is now pending and its execution is therefore initiated or triggered by the control device.

[0110] In some embodiments, the extracorporeal blood tubing set is at least two-part, preferably with a detachable connection between the arterial line or patient line or the venous line or patient line on the one hand and the chamber on the other.

[0111] Some or all embodiments according to the invention may have one, several or all of the advantages mentioned above and / or below.

[0112] An advantage of the present invention may be that the treatment device is hygienically decoupled from the blood tubing set via the rinsing port when the rinsing fluid is emptied from the blood tubing set. This may allow the rinsing port to be accessed, unlike previously possible, before Fresenius Medical Gare Deutschland GmbH

[0113] Each treatment must be disinfected, which can help save time, manpower and costs.

[0114] A further advantage of the present invention is that, in connection with emptying the blood tubing set via the flushing port, no contamination by water bridges, for example between the flushing port and the flushing port connector or between the blood tubing set and the hydraulics of the treatment device, occurs. This is also possible because, according to the invention, the flushing port connector, when connected to the flushing port, does not come into contact with, nor need to come into contact with, sections or walls of the flushing port that are typically moist, e.g., from previous treatments. This directly contributes to improved hygiene and thus to patient safety.

[0115] The fact that the rinsing port of the treatment device and the rinsing port connector, which is usually part of the blood tubing set, do not have to be permanently connected to each other in some designs can advantageously open up new design possibilities for these components, which can then indirectly lead to cost savings, e.g. on the machine side, in the blood tubing set, etc.

[0116] Alternatively or additionally, improvements to the touch protection of the flushing port connector or to user-friendliness are also possible within this framework. Upgrading the treatment device may require fewer steps because manual opening of the flushing port is no longer necessary. Users can advantageously upgrade at any time and are not dependent on Fresenius Medical Gare Deutschland GmbH.

[0117] The treatment device is now complete with the preparation of the irrigation port. This can also help save time and therefore costs.

[0118] Automatic opening and closing of the rinsing port can also significantly improve user safety. Since the user does not need to / cannot open the rinsing port manually, there is no longer a risk of scalding or burns from unauthorized manual opening of the rinsing port during cleaning. Locking the manual rinsing port can further enhance safety.

[0119] The present invention advantageously ensures a germ-free environment at the connections between the disposable device and the treatment device.

[0134] Fig. 1 shows a schematically simplified process diagram of one embodiment of the hydraulic side of a

[0135] erf indungsgemäßen mediz int echni sehen treatment device 2000 (short:

[0136] Treatment device 2000), here a blood treatment device which could be connected to an extracorporeal blood tubing set for the treatment of a patient using a blood filter or dialyzer. The blood filter, extracorporeal blood tubing set and patient are not shown in Fig. 1, but a connection or connector 303a for connecting a dialyze fluid inlet line 104 to the inlet side and a connection or connector 303b for connecting a dialysate outlet line 102 to the outlet side of the

[0137] Blood filters.

[0138] An optional compressed air source 175, for example a compressor, for introducing air or sterile air along a fluid line 2002 of the treatment device 2000 assigned to and / or running within the interior of a treatment device 2000 is clearly visible and is equipped with at least one optional substitute port 100, optional Fresenius Medical Gare Deutschland GmbH

[0139] via a filter F42 and / or a first valve V42 in fluid connection .

[0140] The substituatport 100 serves during the treatment of a patient to establish a fluid connection between at least the fluid line 2002 and a connector of a fluid line of a disposable, in particular a blood tubing set or a blood cassette (not shown in Fig. 1), which is associated with the outside of the treatment device 2000.

[0141] Furthermore, a rinse port 101, also known as a rinse port or drain port, is provided for establishing another fluid connection between the fluid line 2002 of the

[0142] Treatment device 2000 and the exterior of the treatment device 2000 are provided.

[0143] An optional additional filter F07 may be provided in the fluid line 2002, for example to reduce or completely retain impurities that could enter the treatment device 2002 via the (open) rinsing port 101.

[0144] The compressed air source 175, arranged for introducing air or sterile air downstream into both ports 100, 101 along and / or by means of the fluid line 2002, is here by way of example arranged upstream of the substitute port 100, and the rinsing port 101 is by way of example arranged downstream of the substitute port 100.

[0145] Compressed air from the compressed air source 175 can thus flow along the fluid line 2002 into both the substitute port 100 and the rinsing port 101, a suitable Fresenius Medical Gare Deutschland GmbH

[0146] Valve control is assumed. According to the invention, it is irrelevant whether the line 2002 runs through the respective port 100, 101, or whether the respective port 100, 101 is located on the fluid line 2002, for example, connected to it by a branch line or the like, as is exemplified in Fig. 1. There, the fluid line 2002 passes through the flushing port 101, while the substitute port 100 is located on it and connected to it by a short connecting line.

[0147] Downstream of the two ports 100 and 101, in fluid line 2002 or in fluid communication with fluid line 2002, a first pressure source 169 is arranged, for example, configured as a flow pump. When a "pressure source" is mentioned here, this also includes the possibility that it can be a vacuum source. For example, a vacuum can be created in fluid line 2002 or in sections thereof by means of the first pressure source 169, which could draw fluid from the flushing port 101.

[0148] An optional second pressure source 159, also configured here as a flow pump, is arranged upstream of the rinsing port 101 and / or the substitute port 100. It can be used to fill the substitute port 100 with liquid, e.g., from a liquid source 155. The second pressure source 159 can be used for degassing parts of the fluid line 2002. Additionally or alternatively, fluid can be supplied from a liquid source 190. This can be a secondary air separator for the treatment device 2000. Fresenius Medical Gare Deutschland GmbH

[0149] A number of valves V22, V23, V24, V25, V26, V31, V32, V33, V42, and V43 are optionally arranged to prevent fluid flow, including along fluid line 2002. For example, valve V42 is arranged between pressure source 175 and substitute port 100, and valve V32 is arranged between substitute port 100 and purge port 101. Optionally, valve V33 is arranged between purge port 101 and the first pressure source 169.

[0150] A control and / or regulating device 150 (hereinafter also referred to as: control device 150) can be connected to any of the components of the treatment device 2000 mentioned herein by means of a wired or wireless signal connection for the control or regulation of the treatment device 2000. The control device 150 can be enclosed within the treatment device 2000.

[0151] On the left in Fig. 1, an optional mixing device 161 is shown, which provides a predetermined mixture for the respective solution from containers A (for A concentrate via concentrate supply 166) and B (for B concentrate via concentrate supply 168) for use by the treatment device 2000. The solution preferably contains water (online, e.g., as reverse osmosis water or from bags) from the liquid or water source 155, which can be supplied to the system, for example, by means of the second pressure source 159, heated, e.g., by means of an optional heat exchanger 157.

[0152] An optional pump 171, which can be referred to as a concentrate pump or sodium pump, is fluidically connected to the optional mixing device 161 and preferably to a source of sodium, such as container A, and / or Fresenius Medical Gare Deutschland GmbH

[0153] From this, it pumps out. An optional pump 173, which is assigned to container B, for example for bicarbonate, can be seen.

[0154] Figure 1 also shows an optional drain or discharge line 153, which preferably terminates in a drain (not shown in Figure 1) into which liquids, e.g., rinsing fluid or effluent generated during patient treatment, can be disposed of. The discharge line 153 can be in fluidic connection with the fluid line 2002 for this purpose.

[0155] In the arrangement shown, several pressure sensors S03 and S07 can be provided. Pressure sensor S03, located upstream of the blood filter in the dialysis fluid inlet line 104 during patient treatment, and pressure sensor S07, located downstream of the blood filter in the dialysis outlet line 102 during patient treatment, can be used to measure the filtrate pressure or the membrane pressure of the blood filter. Additional optional pressure measurement points can also be provided.

[0156] The optional online mixing device for the dialysis fluid allows for variation of its sodium content within certain limits, controlled by the control unit 150. In particular, the measured values ​​obtained by the optional conductivity sensors 163a and 163b can be used for this purpose. Should an adjustment of the sodium content of the dialysis fluid (sodium concentration) or the substitute be necessary or desired, this can be achieved by adjusting the flow rate of the optional sodium pump 171. Fresenius Medical Germany GmbH

[0157] Furthermore, the treatment device includes 2000 means for conveying fresh dialysis fluid and dialysate. For example, a valve V24 can be provided between the first flow pump 159 and the connector 303a for the blood filter, which would open or close the inlet to the blood filter during patient treatment. The second flow pump 169 is, for example, provided downstream of the connector 303b for the blood filter, which would convey dialysate to the drain line 153 during patient treatment. Another valve V25 can be provided between the connector 303b for the blood filter and the second flow pump 169, which would open or close the outlet of the blood filter during patient treatment.

[0158] Furthermore, the treatment device 2000 optionally includes a device 161 for balancing the flows in and out of the dialyzer 303 on the machine side. The balancing device 161 is preferably arranged in a line section between the second pressure source 159 and the first pressure source 169.

[0159] The treatment device 2000 optionally also includes means for the exact removal of a fluid volume specified by the user and / or by the control device 150 from the balanced circuit, such as the ultrafiltration pump 131.

[0160] Sensors such as the optional conductivity sensors 163a, 163b may be provided and serve to determine the temperature-compensated conductivity in some versions. Fresenius Medical Gare Deutschland GmbH

[0161] Conductivity and the fluid flow upstream and downstream of dialyzer 303.

[0162] Temperature sensors 165a and 165b can be used individually or in groups. The temperature values ​​they provide can be used to determine a temperature-compensated conductivity.

[0163] Additional river pumps may be provided as a supplement to or alternative to, for example, those with reference numbers 159, 169, 131.

[0164] Based on the measured values ​​of the aforementioned optional sensors, the control device 150 determines the electrolyte and / or fluid balance in some versions.

[0165] Optional filters F04 and F05 can be connected in series.

[0166] The filter F04 serves here as an example to produce sufficiently pure dialysis fluid using the mixing device 163, even with the use of non-sterile water, which could flow through the blood filter 303 during the treatment of a patient, e.g. in the countercurrent principle.

[0167] Filter F05 serves as an example here to generate sterile or sufficiently filtered substitute from the sufficiently pure dialysis fluid leaving the first filter F04 by filtering out, for example, pyrogenic substances. This substitute could then be safely administered to the patient's extracorporeal blood flow and thus ultimately to the patient's body. Fresenius Medical Germany GmbH

[0168] A fluid source 190 downstream of the flushing port 101 can serve as a reservoir or equalization tank. It can be arranged in such a way that fluid can flow through it and / or store fluid. It can have an indirect and / or a direct connection to a drain for fluids. It can be arranged in fluid communication with the fluid line 2002.

[0169] The treatment device 2000 is shown in Fig. 1 as an optional device for hemo (dia) filtration.

[0170] Hemodialysis devices also fall under the present invention, although not specifically illustrated by means of a figure.

[0171] The present invention is not limited to the embodiment described above; this serves only for illustration.

[0172] The arrowheads shown in the figures generally indicate the usual or current flow direction of a fluid.

[0173] Fig. 2 shows a schematically simplified rinsing port 101 of a treatment device 2000 according to the invention in a partial sectional view with a vertically arranged receptacle 141 for the detachable receiving of a rinsing port connector 140 or a section thereof.

[0174] Reference is made to the reference symbols and explanations in Fig. 1 to avoid repetition. Fresenius Medical Germany GmbH

[0175] In the example of Fig. 2, a section of the housing H of the treatment device 2000 can be seen, on which, in this embodiment, for example on the machine front of the treatment device 2000, a rinsing port 101 is arranged.

[0176] The flushing port 101 in turn comprises a fluid line 2002, which is optionally arranged entirely or at least partially inside the treatment device 2000.

[0177] The fluid line 2002 is arranged to receive fluid supplied to the rinsing port 101 from an external part of the treatment device 2000 during its use. This can occur, in particular, from an extracorporeal blood tubing set 300 via the rinsing port connector 140 and, for example, following gravity, solely by gravity, or even solely by gravity, thus supplying the fluid to the rinsing port 101.

[0178] The flushing port 101 or the fluid line 2002 has an opening 0 for receiving liquid into the flushing port 101 or into the fluid line 2002. This is further indicated in Fig. 2 by a double arrow, which lies in the plane of the opening in Fig. 2.

[0179] The flushing port 101 or the fluid line 2002 is provided in or on other components of the treatment device 2000 such that the opening 0 is vertically open upwards in the operating state of the treatment device 2000 or can be brought into a vertically open upwards state, for example by opening an optional cover. The vertical direction (vertically upwards) is indicated in Fig. 2 by an arrow and the reference numeral 149. Fresenius Medical Germany GmbH

[0180] The flushing port connector 140 is designed as a “T” piece in the example of Fig. 2, which is preferably detachably received in the receptacle 141 by means of at least one of its two “side arms”.

[0181] The flushing port connector 140 can, here as in any other embodiment, be, for example, a disposable and / or an injection-molded part. It can be understood as an adapter. A special geometry that might be necessary to be form-fit and / or force-fit connected to the flushing port 101, for example according to the key-lock principle, is not required here, but may be in some

[0182] However, it should be provided for in the form of leadership.

[0183] In the present example, the receptacle 141 is designed as a holder which is arranged on the outside of the treatment device 2000. For receiving the rinsing port connector 140, it has, by way of example, two arms, each with a recess for the side arms of its "T"-piece. It is arbitrarily designed and / or arranged such that the third opening, i.e., e.g., the base of the "T", lies vertically above or over the opening 0 of the rinsing port 101 or the fluid line 2002.

[0184] In other embodiments, the flushing port connector 140 and the receptacle 141 for this purpose can be designed or arranged differently than shown in Fig. 2, but preferably in relation to the flushing port 101 or the fluid line 2002 such that the fluid accumulating in the flushing port connector 140 flows out following gravity, preferably only by gravity or solely by gravity. Fresenius Medical Gare Deutschland GmbH

[0185] causes, i.e., by means of free fall, to fall into the flushing port 101 and / or directly into the opening 0.

[0186] For this purpose, the receptacle 141 is preferably arranged such that the section of the rinsing port connector 140 of the extracorporeal blood tubing set 300 or the other section of the extracorporeal blood tubing set 300 is received above or vertically above the opening 0 in the use of the treatment device 2000.

[0187] Alternatively or additionally, the recording 141 is preferably arranged in such a way as to include the section of the

[0188] To accommodate the flushing port connector 140 of the extracorporeal blood tubing set 300 or the other section of the extracorporeal blood tubing set 300 at a predetermined distance from the opening 0.

[0189] The flushing port connector 140 or the other section can be a connecting section in or by means of which the arterial line 301 and the venous line 305 are directly or indirectly connected to each other, preferably in fluid connection.

[0190] The predetermined distance may be a structural gap or interruption.

[0191] The predetermined distance can correspond to the distance of free fall of the liquid or denote its length.

[0192] The receptacle 141 can be integrated into or connected to the flushing port 101. Thus, the receptacle 141 can be part of the flushing port 101 and designed to accommodate a Fresenius Medical Gare Deutschland GmbH

[0193] To at least partially accommodate the flushing port connector by establishing a detachable connection.

[0194] In other versions, the flushing port 101 includes the fluid line 2002 with the opening 0.

[0195] In the example shown in Fig. 2, the treatment device 2000 further comprises a cover 145, here a hinged cover. The cover 145 is optionally provided with a sealing element D, preferably a sealing ring. The cover 145 serves to close the opening 0. A control and mechanism, e.g., a mechanical device, for opening it may be provided.

[0196] Thus, the treatment device 2000 in the example of Fig. 2 has a drive mechanism, which preferably comprises an electric motor 147. The drive mechanism serves to open or close the lid 145.

[0197] The control device 150 (not shown in Fig. 2, see Fig. 1) can be configured to drive the drive mechanism.

[0198] The treatment device 2000 can further include a pump 131 (not shown in Fig. 2, see Fig. 1) in or on the fluid line 2002, which is suitable and provided for drawing fluid from the rinsing port 101 and into the fluid line 2002.

[0199] To determine a fluid level or flow in the flushing port 101 or in the fluid line 2002, at least one sensor 143 can be provided. The sensor 143 can be located on the outside of the fluid line 2002, as in the example shown in Fig. 2. In other embodiments, it can be located inside the fluid line 2002. Fresenius Medical Gare Deutschland GmbH

[0200] or be located in or on the flushing port 101. The sensor 143 can be in signal communication with the control device 150 (see Fig. 1) or be prepared for this purpose. In these cases, the control device 150 (see Fig. 1) can be configured to cause the pump 131 to draw fluid from the flushing port 101 and into the fluid line 2002 upon receiving a signal from the sensor 143.

[0201] In the example shown in Fig. 2, the treatment device 2000 further comprises a cover C, which is attached to its machine front or housing H and faces the outside of the treatment device 2000. The cover C can be moved from a first, preferably closed, position to a second, preferably open, position.

[0202] The cover C is preferably positioned such that, in its first position, it covers both the opening 0 of the irrigation port 101 and the receptacle 141 for the section of the irrigation port connector 140 of the extracorporeal blood tubing set 300 or the other section of the extracorporeal blood tubing set 300 to the side and / or front. Preferably, this is not the case in its second position. The cover C may have openings, e.g., lateral ones, for passing tubing or line sections through it.

[0203] Fig. 3 shows the flushing port 101 of Fig. 2 in a 3D representation from an oblique top view.

[0204] Reference is made to the reference symbols and explanations of the preceding figures to avoid repetition. Fresenius Medical Germany GmbH

[0205] This illustration clearly shows the optional cover C, which in this embodiment is depicted in its first position. In this position, it covers both the opening 0 of the irrigation port 101 and the receptacle 141 for the section of the irrigation port connector 140 of the extracorporeal blood tubing set 300 or the other section of the extracorporeal blood tubing set 300 laterally and forwards (in Fig. 3 in a radial or horizontal direction). In the example shown in Fig. 3, the cover C has lateral openings or recesses for passing through sections of tubing or tubing. If, for example, the cover is less high than shown in Fig. 3, it may be possible to omit such openings or recesses.

[0206] Fig. 4 shows in a second embodiment a schematically simplified flushing port 101 of a treatment device 2000 according to the invention in a partial sectional view with a receptacle 141 for releasably receiving a flushing port connector 140 or a section thereof.

[0207] In the example shown in Fig. 4, the irrigation port connector 140 is designed as an "L"-shaped piece, which is preferably detachably received, for example clipped, into the receptacle 141. In this example, the receptacle 141 is designed as a holder, which is optionally arranged on the outside of the treatment device 2000. For receiving the irrigation port connector 140, it has, for example, two arms for a section of the "L" and is arranged such that the other part of the "L", which is optionally arranged at right angles to it, extends vertically with a free end above the receptacle 141.

[0208] The opening 0 ends. This free end can protrude into, or be connected to, the flushing port 101. The L-shape shown here is purely exemplary; the flushing port connector 140 could have other shapes, e.g., a straight or elongated shape ("I").

[0209] In contrast to the preceding embodiments, in the example of Fig. 4 the free fall path is located within the housing or hydraulics of the treatment device 2000. The free fall path is preferably achieved by a corresponding design of the flushing port 101, for example as a sufficiently large space into which the flushing fluid to be disposed of can fall from the flushing port connector 140 into the flushing port 101, also following gravity, only by gravity or already solely by gravity.

[0210] For this purpose, the free end E of the flushing port connector 140 can extend into the flushing port 101, as shown in Fig. 4, or end before the start of the flushing port 140.

[0211] If, as in the example of Fig. 4, the connection between flushing port 101 and flushing port connector 140 is not airtight, i.e., if there is a connection from the inside of flushing port 101 to the atmosphere, then atmospheric pressure also prevails inside flushing port 101. In this case, the flushing fluid discharged from flushing port connector 140 into flushing port 101 can be pumped out of flushing port 101 towards fluid line 2002, or along it, by means of a pump, for example, pump 131 (not shown here, see Fig. 1), e.g., as described in Fig. 2. Reference is made to the explanations there to avoid repetition. Fresenius Medical Germany GmbH

[0212] To determine the liquid level or flow rate in the flushing port 101 or in the fluid line 2002, at least one sensor 143 can also be provided in this embodiment. Reference is also made here to the descriptions in Fig. 2.

[0213] Fig. 4 shows the opening 0 as the beginning of the fluid line 2002 at the transition from the flushing port 140 to the fluid line 2002 leading from it. The flushing port 140 has a cross-sectional area that is preferably larger than the cross-sectional area of ​​the opening 0 and / or preferably larger than the cross-sectional area of ​​the free end E of the flushing port connector 140, as also shown in Fig. 4. In this way, the flushing fluid can fall freely in sections on its way into the fluid line 2002; wetting of side walls, etc., is advantageously not necessary, as can already be seen and described in Figs. 2 and 3 as well as in the following Fig. 4a.

[0214] Fig. 4a shows a schematically simplified representation of a third embodiment of a flushing port of a treatment device 2000 according to the invention in a partial sectional view with a receptacle 141 for the detachable reception of a flushing port connector 140.

[0215] The embodiment of Fig. 4a largely corresponds to the embodiment of Fig. 4. Therefore, reference is made to the reference numerals and embodiments of Fig. 4, and only the differences will be discussed below. Fresenius Medical Germany GmbH

[0216] In contrast to the embodiment shown in Fig. 4, in the example shown in Fig. 4a the connection between flushing port 101 and flushing port connector 140 is sealed airtight, here by means of a closure 320, i.e., there is no connection between the interior of flushing port 101 and the atmosphere. In this case, the air cushion present inside the flushing port pushes the accumulating liquid towards fluid line 2002. Pumping is therefore unnecessary in this embodiment.

[0217] Fig. 5 shows a schematically simplified process diagram of an embodiment of the hydraulic side of a treatment device 2000 according to the invention analogous to Fig. 1, in which an extracorporeal blood tubing set 300, represented in Fig. 5 only by the line sections shown and described below, is connected to the flushing port 101.

[0218] Reference is made to the reference symbols and explanations of the preceding figures in order to avoid repetition.

[0219] An arterial line 301 has a first end for its connection, directly or indirectly, with a dialyzer and a second end for its connection, directly or indirectly, with a patient, particularly during treatment.

[0220] A venous line 305 has a first end for its connection, directly or indirectly, to the dialyzer, and a second end for its connection, directly or indirectly, to the patient, particularly during treatment. Fresenius Medical Gare Deutschland GmbH

[0221] Dialyzer and patient are not shown in Fig. 5.

[0222] The extracorporeal blood tubing set may further include a venous bubble catcher or a venous air separation chamber 325 arranged in the venous line 305, and a ventilation device 327 may be provided for the removal of the separated air.

[0223] Furthermore, the extracorporeal blood tubing set 300 in the example of Fig. 5 has a chamber 310 .

[0224] The chamber has a receptacle 301a for detachably receiving the second end of the arterial line 301 and a receptacle 305a for detachably receiving the second end of the venous line 305, to establish a fluid connection between the arterial line 301, the venous line 305 and an interior I of the chamber 310. The first receptacle 301a and the second receptacle 305a are preferably associated with a first end of the chamber 310.

[0225] The chamber 310 further has an outlet 310a, through which fluid which was supplied to the interior I of the chamber 310 by means of the arterial line 301 and the venous line 305 can leave the interior I of the chamber 310 again.

[0226] In the example shown in Fig. 5, the outlet 310a of chamber 310 is connected to a flushing port connector 140 for connecting the extracorporeal blood tubing set 300 to the flushing port 101 of the treatment device 2000 in a fluid connection. The flushing port connector 140 can be conventional or optionally adapted to the flushing port 101, e.g., by a form-fit or force-fit connection. Fresenius Medical Germany GmbH

[0227] In some embodiments, the cross-sectional area of ​​the interior I of chamber 310 is larger than the combined cross-sectional areas of the second ends of the arterial conduit 301, or the receptacle 301a therefor, and of the venous conduit 305, or the receptacle 305a therefor.

[0228] Inside I of chamber 310 a free fall path is provided for liquid, between the second end of the arterial line 301 and / or the second end of the venous line 305 on the one hand and the outlet 310a of chamber 310, which faces the flushing port 101 on the other hand .

[0229] Fluid leaving chamber 310 via outlet 310a finds its way via flushing port connector 140 and flushing port 101 into fluid line 2002.

[0230] The free fall section within chamber 310 provides or contributes to the hygienic decoupling between the blood and hydraulic sides. Chamber 310, including all parts of the extracorporeal blood tubing set 300 extending to or into the rinsing port 101 of the treatment device 2000, would preferably be disposed of after filling.

[0231] The extracorporeal blood tubing set 300 (represented in Fig. 5 only by the aforementioned tubing sections) is designed for treatment using a blood treatment device, in particular a dialysis device, hemodialysis device, hemofiltration device or

[0232] Hemodiafiltration device, in particular by means of a device for acute, chronic or continuous renal replacement therapy (CRT). Fresenius Medical Germany GmbH

[0233] Fig. 6 shows a schematically simplified flow diagram of the inventive method for at least partially emptying an extracorporeal blood tubing set 300 connected to a treatment device 2000, or for arranging it for this purpose, in an exemplary manner.

[0234] From a leadership form.

[0235] Reference is made to the reference symbols and explanations of the preceding figures in order to avoid repetition.

[0236] In this process step Ma, a treatment device 2000 is provided with a flushing port 101 and a fluid line 2002 for draining liquid from the flushing port 101 in the treatment device 2000, wherein one end of the fluid line 2002 faces the flushing port 101 in order to receive liquid from it into the lumen of the fluid line 2002. The fluid line may have an opening 0 at this end for this purpose.

[0237] Procedure step Mb represents the provision of an extracorporeal blood tubing set 300, which in turn comprises an arterial line 301 and a venous line 305. The arterial line 301 includes a first end for connection, directly or indirectly, to a dialyzer, and a second end for connection, directly or indirectly, to a patient. The venous line 305 includes a first end for connection, directly or indirectly, to the dialyzer, and a second end for connection, directly or indirectly, to the patient.
