Description

System and method for automated cannulation

The invention relates to a system for automated cannulation of the blood vessels of patients and a corresponding method, in particular for hemodialysis.

Blood vessel puncture, also referred to as cannulation, is a routinely required step in the medical treatment of many patients in which a fluid connection is created between the patient's bloodstream and an external fluid system, particularly a cannula. Cannulation is performed in the medical practice by physicians or trained personnel. The quality of the vascular access created by the cannulation depends on a large number of parameters, which are characterized in particular by the individually and temporally variable abilities of the medical personnel and physical properties of the patients to be treated as well as by the diversity of the technical aids used in the puncture. In order to standardize the cannulation, cannulation machines have been developed which autonomously prepare a cannulation procedure on the patient and autonomously perform the cannulation by means of suitable sensors and motor systems. Such Kanülierautomaten and technical means used therein are known for example from US 2015/0065916 A1, WO 2015/052719 A1 and WO 2010/029521 A2.

Patients with chronic conditions regularly require repeated punctures of the blood vessels to ensure the required treatment. One such chronic disease is kidney failure, which among other things leads to the failure of the natural blood purification function. This can be replaced by technical solutions. Hemodialysis machines are extracorporeal filter systems used as artificial kidneys into which the patient's blood is passed to be cleaned and treated before being returned to the patient's bloodstream. The removal of the blood and the return of the blood is usually carried out via a surgically in an arm or leg of the patient subcutaneously created, artificial connection between a vein and an artery. This compound may consist of a prepared to the patient's own vessel portion or of an artificial material and is referred to as a fistula or arteriovenous fistula (AV fistula, AVF). The most widely used permanent vascular access in chronic hemodialysis patients is a native arteriovenous fistula. After placement of the native arteriovenous fistula, it becomes more intense due to increased blood flow, making repeated puncture easier for dialysis treatment.

Hemodialysis must be performed regularly, typically at intervals of a few days. This leads to a high mechanical load on the vessel, or the arteriovenous fistula. In order to gain access to a vessel or an arteriovenous fistula, various techniques are known which aim to preserve the vessel as much as possible in the course of the recurring punctures. In the rope ladder puncture, a new cannulation point is searched for each treatment, which is a distance from the previous, for example, about 2 cm. Usually, in this method, the puncture series is started at the lower end of the vessel and then continued upward until the upper end is reached and the process is started again from below. In this case, the practitioner must observe the positioning scheme exactly in order to enable the healing of the punctured vessel positions. In contrast, in the buttonhole technique, a needle is always inserted at exactly the same location with the same angle. Over time, a scar cylinder is formed, in which the formed thrombus is repeatedly displaced during puncture and thus becomes more resilient. It has been observed that buttonhole technique results can be improved if the puncture is always performed by the same treatment personnel. Due to the frequency of punctures in hemodialysis patients, the arteriovenous fistula is generally exposed to a particularly high load independent of the puncture technique, which can lead to changes in the skin surface and the nature of the arteriovenous fistula and its course. The evaluation of observations of the hemodialysis patients on which this invention was based showed that the nature and course of the arteriovenous fistula can develop very differently in the course of the treatments from patient to patient. Thus, the puncture in hemodialysis patients is a relatively complex process that challenges the skilled treatment staff. The configuration of Kanülierautomaten required in such situations, a relatively high cost.

The present invention has for its object to provide a more efficient technical solution for cannulation under variable operating conditions, as found in particular in hemodialysis.

To solve this problem, the automated cannulation system according to claim 1 and the automated cannulation method according to claim 15 are used. Preferred embodiments of the invention are the subject of the subclaims and the present description of the invention.

The inventive system for data-dependent automated cannulation of the blood vessels of patients, in particular for Hämodialsye, comprises: at least one Kanülierautomaten that is set up for automated cannulation of the blood vessels of patients, at least one control system having at least one data processing device and the execution of a At least one user interface device, by means of which a user input to the control system is enabled, is registered by a patient on the control system, as a result of this registration process from the control system individually assigned to the registered patient Patient identifier is used, which is referred to as a registered patient identifier, and wherein the at least one control system, in particular the at least a control method is set up to determine the program parameters as a function of the registered patient identifier and to control the at least one automatic cannulation device in dependence on the registered patient identifier. The system according to the invention is adapted to adapt the automated cannulation individually to the specific starting conditions present in a specific patient. Much of this adaptation can be done as a preparation before the automated process of cannulation, and therefore need not take place during cannulation. This is possible because the patient was previously logged on to the system via a user interface. One Such a system is particularly efficient and offers the advantage of extended deployment and design options. In particular, such a system offers the advantage of being able to identify and provide extensive patient data for data storage that can be used in subsequent automated cannulation procedures by this system to further enhance reliability.

In particular, as a system for cannulation of blood vessels, especially native arteriovenous fistulas in hemodialysis patients, the system offers the advantage that the precision of Kanülierautomaten in combination with their patient-specific and data-based control lead to particularly reliable puncture results while preserving the vessel in the course of repetitive hemodialysis , Automated cannulation operations begin with the understanding of the present invention and, as described below, after the body part of the patient to be punctured has been inserted into a treatment room of the cannulation machine, e.g. by the patient himself or by medical treatment personnel.

The term "cannulation" is understood to mean a process in which a cannula is inserted into the blood vessel by puncturing the skin and puncturing the wall of a blood vessel in the body part of the patient, so that the distal end of the cannula is arranged in the blood vessel, and the proximal one The end of the cannula is arranged outside the body part, so that a fluid connection between the cannula and the blood vessel is provided, via which fluid, in particular blood and / or fluid media, can be exchanged via the fluid connection. in that the fluid is transferred from the bloodstream of the patient into an extracorporeal fluid system, that is to say located outside the patient's body, in particular for fluid storage or fluid guidance, and / or that the fluid is transferred from the extracorporeal system into the bloodstream.

A cannula is a tubular body, particularly a rigid or flexible hypodermic needle, having a lumen, with a geometry and outer dimensions suitable for use in cannulation of the blood vessel. The system according to the invention for data-dependent automated cannulation of the blood vessels of patients, hereinafter also abbreviated as "system", contains in particular at least one device and at least one method which in particular jointly solve the underlying technical problem several Kanülierautomaten, preferably at least one control system and preferably one or more user interface devices.

The methods used in the system preferably include the control method, preferably the selection method for selecting the program parameters depending on the registered patient identifier, and preferably a registration method by which a patient is logged on the control system, wherein the result of the registration process includes that the control system registered patient ID is present.

A control system, or a control device of the control system, or a control device of a device of the system, in the context of the present invention, in particular, in particular a data processing device, in particular a data processor, that is, a processing unit (CPU) for processing data, and / or a volatile or permanent Data memory, and / or a microprocessor or is a data processing device. A computing unit of the control system is preferably set up to control the system and in particular to control the cannulation process. The control system may be formed by a single control device of the system. Preferably, the control system comprises a plurality of control devices, which may be stand-alone devices or may be components of other devices of the system, in particular the at least one user interface device and / or the at least one cannulation device. In particular, these control devices may be partially or all organized in a network for data exchange. In the event that the at least one user interface device includes its own control device and / or the at least one automatic cannula device includes its own control device, these control devices can be regarded as components of the control system. But it is also possible that the control system does not include these optional control devices. The control system is preferably adapted to carry out the application method and the control method, in particular by a suitable for this purpose formed by a data processor executable program code.

The control system of the system and / or the at least one automatic cannula and / or the user interface device can - in particular all - be integrated in a physical device unit, but may each also be a separate physical device unit. A physical device unit may, in particular, be a module which is at least data-connected to the system or can be connected. The control system and / or the at least one automatic cannula and / or the user interface device or components of these components can also be implemented at least partially by software functions or, in particular, can partially implement program code. A cannulation machine may have a controller, e.g. a computer which, in combination with software functions, at least partially implements one or more functions of the control system of the system and / or of the at least one cannulation machine and / or the user interface device.

A module may in particular comprise the control system or its components and / or a user interface device. A module is a device which is separate from other devices, in particular the devices of the system, and / or a device which can be separated from the other device, in particular automatic cannulas. A Kanülierautomat may have a connecting device by which the module with the Kanülierautomaten is mechanically connected, in particular by means of a user-detachable connection. A module can be portable, ie transportable by a user. The module can also be firmly connected to the Kanülierautomaten. The modular design offers advantages in the provision of the system. A portable module also provides greater flexibility in using the system.

In a preferred embodiment of the system, the control system and / or preferably the at least one user interface device are part of the at least one cannulation machine. In this case, the at least one automatic cannula preferably has the control system and / or the at least one User interface device. In a compact embodiment, therefore, the system has exactly one cannulating machine, which has the control system and the at least one user interface device. For the preferred embodiment of the system according to which it has at least two automatic cannulas, the control system is preferably a component of a first of these at least two cannulas. The at least one user interface device is in this case preferably part of the first of the at least two Kanülierautomaten, or is part of at least one other, second Kanülierautomaten, or forms a separate device or its component. The use of at least two Kanülierautomaten in the system offers the advantage of increased throughput through the simultaneous operation of at least two Kanülierautomaten, which are particularly advantageous in systems that are set up for use in hospital operation.

In addition, the provision of multiple automatic cannisters offers the possibility that at least two of the automatic cannulas are set up in different ways to be used in different situations. In these situations, different types of patients may be considered by the apparatus, e.g. the body size of the patients, which distinguishes in particular children and adults. Further, in these situations the puncture of vessels on different parts of the body may be provided by equipment specification, e.g. a first Kanülierautomat for cannulation can be arranged on one arm and a second Kanülierautomat for the cannulation can be arranged on a leg. An adaptation of the apparatuses may be particularly in the dimensioning of components, e.g. the different dimensions of a fixing device for fixing the body part, which has the blood vessel to be punctured.

Another preferred feature of the system, which includes a plurality of automatic cannulas, includes having at least two of these automated cannulas positioned at geographically different positions. As a result, a supply of automatic cannulation can be provided in each case for different geographical positions, which in particular are controlled by a common control system. These geographically different positions can in particular within a clinic, eg in different rooms of one or several buildings and / or in different floors of the building, or are distributed within a medical care area, especially within a city, or may in principle be distributed regionally, in particular country or worldwide. The control system is preferably a central device with which the geographically differently distributed Kanülierautomaten be controlled. However, it is also possible for a plurality of control devices, in particular geographically distributed differently, of a single control system or a plurality of geographically differently distributed control systems to be provided as components of the system.

In particular, the same number of control systems and Kanülierautomaten can be provided in the system. A Kanülierautomat can each have a control system. The Kanülierautomaten are in this case preferably designed for data exchange with at least one other device, in particular an external device.

The Kanülierautomaten are preferably configured to form a data connection and / or have a data connection to an external device. This external device may be a data storage device or a server to which this data storage device is connected. The data storage device preferably contains a database, the data of which may be stored in particular on at least one non-volatile storage medium of the data storage device. This database may be or may be the patient database. Preferably, the system comprises a data storage device in which a patient database is stored containing the patient records, each containing at least one patient identifier, of a plurality of patients.

A control system 50, 51 of the system 100 is arranged to execute a control method that can control each of the two cannulation machines in response to program parameters. The control system 50, 51 comprises a central control device 50. The control devices 51 each control a Kanülierautomaten 1 and are as Components of the control system 50, 51 is considered, whose task in the clinical system 100 includes performing the at least one automatic cannulation of a body part 30 of a patient in dependence on the patient identification. The control device 50 and the control device 51 each have a data processing device with data processor and data memory, as well as a communication device for establishing a data connection with another communication device of the system. Through the data connections of the devices 1, 80, 90 with the control device 50, this system components are networked in a network for data exchange. In the present case, the network has the control device 50 as the central computer.

The system 100 includes two user interface devices 80, which in the example are embodied as fingerprint scanner authentication devices 80, by means of which the patients previously registered with the system are authenticated. The registration of a patient includes that his data relevant for the clinical recording are recorded, in particular an image of his fingerprint is stored for comparison in a patient database and this patient data of the patient is assigned an intrinsic patient identifier, referred to herein as a patient identifier. After registration of the registered patient, the control system has recorded the patient as a registered patient, his patient ID is after registration as the "registered patient ID".

The system 100 includes a data storage device 90, which may be a hard disk server in which at least one database is stored. Specifically, stored in the data storage device 90 is the patient database accessed by the system from the registered patient identifier to read the patient data of the logged-in patient required for automated cannulation. The patient data can be continuously supplemented by data collected by the system, eg identification data of a recognition device, as well as optional observation data on the course of a completed cannulation or hemodialysis, as well as data of the treatment performed. This results in a patient record, by the accuracy of which the subsequent treatments of the patient in this clinical system can be continuously improved. The patient data in this exemplary embodiment in particular comprise data for the patient to be performed hemodialysis. In particular, these patient data contain vascular structure data which will be described below.

The controller 50 executes the control method of the system, which is program code executable by the data processors. The control method controls the at least one Kanülierautomaten depending on program parameters, and selects after registration of the patient and before the start of cannulation appropriate program parameters, which are patient-dependent, that have been selected depending on the registered patient identifier. For this purpose, the control process carries out a selection process which is stored in the system.

The selection method is adapted to access a data matrix stored in the data storage device 90 and in which the necessary program parameters are linked in dependence on patient data and treatment data and can be determined in this way. The system can be known when registering the patient on the basis of its own stored time schedule or due to user input when logging in that now hemodialysis has to be carried out for this patient. This information can be known as treatment data. Depending on this treatment data, the system can determine in the patient record which patient-specific conditions and data are to be observed during hemodialysis.

These patient-specific conditions and data for hemodialysis may include vascular structure data, data about patient-specific nature and dimensions of fixation tape and swab material or disinfectant, data on the type of cannula to be used in cannulation, etc. The data matrix may contain information that for the treatment " Hemodialysis "the program parameters" vascular structure data "," condition and dimensions of fixation tape and swab material or disinfectant "," type of cannula to be used for cannulation "are to be observed. The system then automatically prepares the automatic cannulation in accordance with these patient-specific parameters by setting the program parameters "Condition and dimensions of fixation band and swab material or disinfectant" to "type of cannula" a cannula "so that the system's loading system 70 can provide the necessary accessories in a standardized accessory container, and by passing the appropriate vascular structure data from the patient record to the cannulation machine selected by the cannulation system or the cannulation machine via the" vascular structure data "program parameter issued the instruction for accessing this vessel structure data.

Apart from hemodialysis-specific information, the patient record may also contain information that is needed for other treatments and is also patient-specific, e.g. Information about the patient's medication to be regularly dispensed by the system.

In the exemplary embodiment of the clinical system, the devices 1, 50, 80, 90 are partially arranged at different geographical positions. Within the same building complex of the clinic, a first group of devices of the system may be arranged. These include, in Figure 1, the devices 1 and 80 connected with solid lines to the control device 50. Of these devices of the system, geographically distinct, e.g. in another building, the data storage device 90 may be arranged, which is preferably associated with the system according to the invention. However, the data storage device 90 can also be used by other clinical systems. Indicated by a dashed line as a link, another user interface device 80 and a canister 1 may be located at a further geographically different location, e.g. in an ambulatory hemodialysis treatment station, e.g. can be stationed at the place of residence of a dialysis patient. Also, this further user interface device 80 and a canister 1 may be mobile, e.g. in an ambulance, a train, or a ship, as long as a data connection to the system is maintained. Figure 2 shows an embodiment of a Kanülierautomaten 1, which is used by the inventive system 100.

The Kanülierautomat 1 has a robot-controlled Werkzeugarmeinrichtung 2. This has a tool arm 2a with joints, which is connected at one end to Kanülierautomat 1 and carries a tool head 2b at the other end. The tool head is present depending on the type of treatment, eg puncture, Fixierbandaufbringung or dabbing, designed as a replaceable module function specific. In the figure, the tool head for the puncture or cannulation is set up and carries a cannula 3, which is to be inserted into the blood vessel in the arm 30 of the patient. Another tool head (not shown) contains the disinfecting device for program-controlled application of disinfectant to the skin points of this patient to be punctured.

The Kanülierautomat 1 has an observation device 5, which in the present case contains a camera, by means of the automatic Kanülierungsvorgang from a distant observer in real time is observable. The video data on the cannulation are also or alternatively stored in the patient data memory.

Kanülierautomat 1 has a detection device 6, with which the position and dimensions of the arm 30 of the patient and the position and structure of the subcutaneous blood vessels of the patient and the morphology of the skin and vessels can be detected. For this purpose, the recognition device 6 has a vascular structure measuring device (not specifically shown) which is set up for the production of at least one image of the blood vessels by means of ultrasound. These measurements can be carried out in particular before cannulation and / or during and / or after cannulation. The vascular structure data generated by the vascular structure measuring device can be stored as patient data and are available in subsequent treatments as historical data that can improve the cannulation patient-specific.

The vascular structure measuring device can also be set up to detect earlier puncture sites on the skin and / or on the blood vessel. The control method can use this information, in particular in dialysis patients, in order to carry out or continue the cannulation according to the rope conductor technique or the buttonhole technique. The information about the buttonhole technique results for the Kanülierautomaten from the patient data. In the buttonhole technique, the automated cannula inserts the cannula at the same angle relative to the blood vessel or arteriovenous fistula into the same position and through the channel of the "buttonhole." An automaton is predestined to apply this buttonhole technique with consistent quality, as in this technique is crucial for success Buttonhole technique is therefore a particularly preferred type of process for performing the cannulation by means of automatic cannulation or by means of control methods. Also in the rope ladder technique, the machine offers advantages over the manual cannulation, as on the one hand in the vessel structure, the blood vessel morphology is determined and known, which can be selected by the control process an optimal next position at a distance to the previous puncture, and on the other hand, the puncture vibration-free with maximum precision is feasible.

Possible steps of the Kanülierautomaten, in particular the Kanülierautomaten 1, and steps of the control method or the inventive method can be derived from the above-described process steps Px, in particular P1 to P8, and the steps Sx, in particular S1 to S1 1.

FIG. 12 shows a first general exemplary embodiment of the method 200 according to the invention, which is used in the previously described system 100. In principle, the method according to the invention preferably provides the method steps which are also carried out in the control method used in the system. The method steps include the step 201: detecting a registered patient identifier by registering a patient with a user interface device in data communication with a data processing control system; the step 202: - determining program parameters in dependence on the registered patient identifier by the control system; and step 203: controlling a cannulation machine adapted for automated cannulation of patient blood vessels and in data communication with the control system, in response to the program parameters, for automated cannulation of a patient's blood vessel in response to its registered patient identifier ,

FIG. 3 shows a further exemplary embodiment of the method 300 according to the invention, in this case for carrying out the double cannulation of an arteriovenous fistula for hemodialysis, in particular using an exemplary embodiment of the system according to the invention, for example the system 100, in an overview. The method 300 provides the following sequence of steps, in this order: Step 310: Prepare the automated cannulation Step 320: Login with patient identification, preparation

Step 330: Analysis of the historical vessel structure data and / or detection of current vessel structure data of the arm 30 introduced in the treatment room 8, for planning the punctures

Step 340: Automatic disinfection of the skin points to be punctured

- Step 350: Automatic execution of the first puncture and cannulation

- Step 360: Automatic execution of the second puncture and cannulation

- Step 370: performing hemodialysis

Step 380: automatic post-treatment of the punctured areas by pressing, swabbing, gauze bandages

Step 320 is alternatively and preferably prior to step 310.

FIG. 4 shows an embodiment of the preparation step 310 (preparation):

The system or control process begins with the analysis of task (310a). This results e.g. from the patient data of the registered patient in combination with a treatment schedule stored in the system. Alternatively, the system was informed of the plan during / before / after the patient's log-on, particularly as treatment data for a scheduled hemodialysis at a particular time.

The system checks whether database entries already exist with regard to the planned hemodialysis and compares these with the treatment plan (310b). The system determines the vascular structure data from the patient database of the (registered) patient and calculates the possible puncture parts using a suitable algorithm (310c). All data are analyzed and measures derived, in particular whether a doctor must be consulted or whether the automated cannulation with subsequent hemodialysis is released (31 Od).

The system determines the exact sequence of automated cannulation procedures followed by hemodialysis (31 Oe). The system sends data about required accessories to the assembly system (31 Of). The system checks whether the availability of the requested accessories, in particular the availability of the desired automatic cannulation machine, is automatically confirmed (310g). In particular, the system selects a suitable fixation band to later fix the needles to the arm (310h). The fixation band is portioned and dimensioned in particular by the placement system in patient-dependent and treatment-dependent selected sections and transmitted in a standardized, automatically operable by Kanülierautomaten accessory container (31 Oi). Suitable catheters or cannulas are patient-dependent and treatment-dependent discarded (31 Oj) and provided in the accessory container (310k). The accessory container is automatically transported to the automatic cannula (3101). The system sends a status update (310m) to the cannulometer.

FIG. 5 shows an exemplary embodiment of the preparation step 320 (login, authentication, with subsequent preparation of the clinical treatment):

The system authenticates the patient (320a). This can be done by means of password, pin or pattern, via chip card, FRID chip, sim card with mTan method, printed digital certificate or 2D code, TAN / iTAN, preferably by means of biometrics. The system quits with an error message if the authentication fails - what can happen if the patient is not yet registered - the registration has already been described and is a separate process. With the registration the system learns about the upcoming treatment - here a hemodialysis. Immediately after logging in, the system will automatically begin, without delay, automatically with the preparation of hemodialysis, whereby no time is lost, which may be crucial in an emergency. In particular, the medical accessory placement system is activated (320d).

The patient-dependent automatically equipped accessory container is transported from the placement system to the automatic cannulation machine (320e). The placement system submits a status report (320f). The accessory container is placed in the cannulation machine (320g). The accessory container, in particular its seal, is automatically checked for integrity in order to guarantee the sterility of the contents (320h). The completeness and sterility of the accessories are registered by the cannula machine, which is now ready for cannulation - this information is displayed on a display of the cannula machine for the user (320i). As a security step, it is provided that a patient's medical attendant authenticates himself to instruct the patient and to release the canister for the patient (320j). In parallel with steps 320e through 320j, steps 320k through 320m are performed. Patient data, in particular vascular structure data and planned puncture sites, are transmitted by the system (320k), in particular from the patient database to the data processing device of the cannulation machine, the consistency of the transmitted data is checked (3201), and the transmission is either repeated until consistency is present or confirmed if it has been transmitted correctly (320m).

The system checks the preparation status (320n) and informs the staff in case of problems (320p) or (320o) decides the progress of the treatment (320q).

FIG. 6 shows an exemplary embodiment of the step of vascular recognition 330 (fistula identification):

The patient positions his arm in the treatment room of the canister (330a). The fixation device positions the fixation elements (330b) and inspects the arm fixation (330c). If the fixation is insufficient, readjust (330d). Detection of the fistula begins (330e). The vascular structure measuring device detects at least one image of the vascular structure containing the fistula, which is known from the patient data, and automatically checks the image for abnormalities, such as stenosis, hematomas, infections, or severe fistula changes (330f). The recognition data is compared with historical recognition data from the patient record (330g). In case of deviations, the automatic vascular recognition is run through again, and if unsuccessful or conspicuous (330i) a doctor is called in (330j). If, in accordance with historical data, the fistula was identified without abnormalities, the fistula and its puncturing technique are confirmed (330k). Then the correct puncture sites are determined based on the previous preparatory analysis and / or by comparing the current vascular structure data with historical data (3301). The detected puncture sites are displayed (330m) on a display of the cannulometer with respect to an image of the arm, especially for safety personnel approval. The readiness for automatic cannulation is indicated (330n) and, in parallel, the willingness to transfer patient data to the database. A physician or the authorized caregiver will be asked for confirmation (330p). FIG. 7 shows an embodiment of the step of automatic skin disinfection of the arm 340 to be punctured:
