Description

Monitoring equipment and method for recommending cannula model thereof

Technical Field

The invention relates to the field of medical equipment, in particular to monitoring equipment and a method for recommending cannula types.

Background

The extracorporeal circulation support technology is being applied to actual clinic more and more frequently, and as one of the extracorporeal circulation support technologies, the extracorporeal membrane pulmonary oxygenation (Extracorporeal Membrane Oxygenation, ECMO) technology leads venous blood of a patient from inside to outside, and after membrane pulmonary oxygenation, the oxygenated blood is returned to the body through a drive pump, so that the extracorporeal circulation support technology can support patients with severe circulation and respiratory failure effectively. ECMO technology has the ability to assist both biventricular and respiratory functions without site limitations, and has been increasingly used in clinical applications in recent years.

When the ECMO is actually established, the choice of the pipeline is often very important, which is an important decision which needs to be made by clinical staff, and the clinical effect of the ECMO and the prognosis of patients are determined to a certain extent. Ultrasound was used to assess target vessel diameters prior to ECMO intubation to reduce intubation complications, as explicitly recommended in the adult extracorporeal membrane oxygenation (ECMO) circulation assistance expert consensus published 2018.

At present, a pipeline selection auxiliary tool based on equipment fusion information is not available clinically. The doctor can only manually collect the information acquired by each device, and ECMO pipeline selection is performed according to experience, so that the intelligent level is low, and the working efficiency of the doctor is low.

Wherein like elements in different embodiments are numbered alike in association. In the following embodiments, numerous specific details are set forth in order to provide a better understanding of the present application. However, one skilled in the art will readily recognize that some of the features may be omitted, or replaced by other elements, materials, or methods in different situations. In some instances, some operations associated with the present application have not been shown or described in the specification to avoid obscuring the core portions of the present application, and may not be necessary for a person skilled in the art to describe in detail the relevant operations based on the description herein and the general knowledge of one skilled in the art.

Furthermore, the described features, operations, or characteristics of the description may be combined in any suitable manner in various embodiments. Also, various steps or acts in the method descriptions may be interchanged or modified in a manner apparent to those of ordinary skill in the art. Thus, the various orders in the description and drawings are for clarity of description of only certain embodiments, and are not meant to be required orders unless otherwise indicated.

The numbering of the components itself, e.g. "first", "second", etc., is used herein merely to distinguish between the described objects and does not have any sequential or technical meaning. The terms "coupled" and "connected," as used herein, are intended to encompass both direct and indirect coupling (coupling), unless otherwise indicated.

As shown in fig. 1, the monitoring device provided by the present invention includes a processor 10, a plurality of sensors 20, and a man-machine interaction device 30.

The sensor 20 is used for detecting vital signs of a patient to obtain corresponding vital sign signals.

The man-machine interaction device 30 is used for man-machine interaction, and comprises an input device 310 and a display 320. The input device 310 is used to receive input from a user to facilitate various input operations by the user, and may include one or more of a keyboard, a mouse, a trackball, a touchpad, a joystick, a touch display screen, and the like. The display 320 is used to output visual information, which may be various types of displays.

The processor 10 may acquire the vital sign signals detected by the sensor 20, process the vital sign signals to obtain the monitored data of the vital sign, and further display the monitored data of the vital sign through the display 320 of the man-machine interaction device 30, such as waveforms and values of various vital signs in fig. 3. In general, the monitoring device is a monitor, and the above method is often adopted.

Of course, the processor 10 may also acquire the monitored data of the vital signs of the plurality of patients from the external medical device (such as other monitors), and further display the monitored data of the vital signs of the plurality of patients through the display 320 of the man-machine interaction device 30. In general, the monitoring device is a central station in the manner described above.

The processor 10 also determines whether the monitored vital sign data exceeds a preset threshold, and if so, displays an alarm message via the display 320.

The processor 10 is also configured to obtain a size of a target vessel; acquiring at least one of equipment information of the extracorporeal circulation equipment, acquiring a preset circulation mode of the extracorporeal circulation equipment, acquiring a preset cannula position and acquiring preset patient information before the extracorporeal circulation of the patient is started; and determining a target cannula model corresponding to the target blood vessel according to at least one of equipment information of the extracorporeal circulation equipment, a preset circulation mode, a preset cannula position and preset patient information and the size of the target blood vessel, and displaying the target cannula model through the display 320. Therefore, the automatic cannula model recommendation is realized, a reference is provided for the cannula of the extracorporeal circulation, and the working efficiency of doctors is improved.

The monitoring device provided by the invention not only can monitor patients, but also can recommend cannula types, and detailed description is given below on specific processes. As shown in fig. 2, the method for recommending the cannula model by the monitoring device comprises the following steps:

step 1, the processor 10 acquires the size of the target blood vessel. For example, the monitoring device is communicatively coupled to the ultrasound imaging device. The doctor operates the ultrasonic imaging equipment to acquire an ultrasonic image of the target blood vessel, and measures the size of the target blood vessel in the ultrasonic image. The processor 10 may obtain the size of the target vessel from the ultrasound imaging device. For another example, after the ultrasonic imaging apparatus obtains an ultrasonic image of the target blood vessel, the processor 10 obtains an ultrasonic image of the target blood vessel from the ultrasonic imaging apparatus, and obtains the size of the target blood vessel based on the measurement result of the ultrasonic image; specifically, the processor 10 may measure the target blood vessel of the ultrasonic image (measure through image recognition or deep learning model, etc.), so as to obtain the size of the target blood vessel; of course, the doctor can also operate the input device to measure the target blood vessel of the ultrasonic image, so as to obtain the size of the target blood vessel.

The target vessel may include a blood-drawing vessel and a blood-return vessel, so that the processor 10 acquires ultrasound images of both vessels and obtains the dimensions of the vessels in both ultrasound images in the manner described above. The two ultrasound images or sizes may be marked by the physician to determine that one size is the size of the blood vessel and the other is the size of the blood vessel. It may also be self-resolved by the processor 10, for example, the ultrasound image is an ultrasound blood flow image, the processor 10 determines the blood vessel type from the ultrasound blood flow image, if one of the two blood vessel types is a vein and one is an artery, the size of the vein is the size of the blood vessel, and the size of the artery is the size of the blood vessel. If both blood vessel types are veins, the two blood vessel types can be indistinguishable, and two corresponding target cannula types can be recommended according to the two blood vessel sizes.

Step 2, the processor 10 acquires at least one of equipment information of the extracorporeal circulation equipment, a preset circulation mode of the extracorporeal circulation equipment, a preset cannula position and preset patient information before the extracorporeal circulation of the patient starts. These information are "preset" because they are acquired before the extracorporeal circulation is started, and are not necessarily information at the time of the subsequent extracorporeal circulation. The more information the processor 10 obtains, the more accurate the recommended cannula model, so this embodiment will be described with respect to obtaining the four types of information described above. There are various ways of acquiring these information, one of which is described below.

As shown in fig. 3, the processor 10 displays the information setting area a through the display 320. The information setting area a shows: a circulation mode setting column a1 for setting a circulation mode, a cannula position setting column a2 for setting a cannula position, and a blood circulation schematic drawing a3 for drawing blood from a blood drawing vessel and returning blood from a blood returning vessel. The doctor can set the circulation mode (such as inputting the circulation mode or selecting the circulation mode) in the circulation mode setting column a1, and set the cannula position (such as inputting the cannula position or selecting the cannula position) in the cannula position setting column a2, so that the processor 10 obtains the preset circulation mode and the preset cannula position through the circulation mode and the cannula position set by the doctor before the patient starts the extracorporeal circulation. The cannula position may be associated with a corresponding blood circulation schematic in advance, and the processor 10 displays the corresponding blood circulation schematic a3 in the information setting area a according to the cannula position set by the user, for reference by the doctor. After the monitoring device is communicatively connected to the extracorporeal circulation device, the processor 10 may obtain the device information from the extracorporeal circulation device, although in some embodiments, the device information may be input by the doctor. The monitoring device and the extracorporeal circulation device work for the same patient, so the monitoring device can take own patient information as preset patient information, and can also obtain the patient information from the extracorporeal circulation device as preset patient information.

And 3, the processor 10 determines a target cannula model corresponding to the target blood vessel according to the size of the target blood vessel and at least one of the equipment information of the extracorporeal circulation equipment, a preset circulation mode, a preset cannula position and preset patient information. For example, the processor 10 determines a target cannula model corresponding to the target blood vessel based on the manufacturer type of the extracorporeal circulation apparatus, the applicable blood vessel type of the extracorporeal circulation, the cannula diameter, and the cannula length.

Specifically, the device information includes or is associated with a vendor type, and the processor 10 determines the vendor type according to the device information.

The circulation mode includes a vein-to-vein mode (V V mode) and a vein-to-artery mode (V A mode), and the preset circulation mode is one of them. The processor 10 may determine the applicable vessel type for extracorporeal circulation according to a preset circulation pattern. For example, the target blood vessel includes a blood drawing blood vessel and a blood return blood vessel, and if the preset circulation mode is a vein-to-vein mode, the processor 10 determines that the applicable blood vessel type of the target cannula model corresponding to the blood drawing blood vessel is a vein, and determines that the applicable blood vessel type of the target cannula model corresponding to the blood return blood vessel is a vein; if the preset circulation mode is the vein-to-artery mode, the processor 10 determines that the applicable blood vessel type of the target cannula model corresponding to the blood drawing blood vessel is vein, and determines that the applicable blood vessel type of the target cannula model corresponding to the blood return blood vessel is artery.

The processor 10 may also determine the appropriate vessel type for extracorporeal circulation based on a preset cannula position. For example, the cannula location includes a vessel name, and the processor 10 determines an applicable vessel type of the target cannula model corresponding to the blood drawing vessel based on the vessel name of the blood drawing vessel, e.g., the vessel name is the right internal jugular vein, and the applicable vessel type is the vein. The blood vessel is usually a vein, so the processor 10 can also directly determine that the applicable vessel type of the target cannula model corresponding to the blood vessel is a vein. The processor 10 determines the applicable blood vessel type of the target cannula model corresponding to the blood return blood vessel according to the blood vessel name of the blood return blood vessel, for example, the blood vessel name is the right femoral vein, and the applicable blood vessel type is the vein.

Of course, the processor 10 may also determine the type of the blood vessel suitable for extracorporeal circulation by combining the preset circulation mode and the preset cannula position, and may mutually verify the type of the blood vessel suitable for extracorporeal circulation by using the two methods, so as to ensure that the determined type of the blood vessel suitable for extracorporeal circulation does not have errors.

Because the vessel diameters at various locations of the human body are within a range, the processor 10 can determine the cannula diameter based on a predetermined cannula location. For example, the monitoring device further comprises a memory, the memory stores preset correspondence between different cannula positions and cannula diameters, and the processor 10 can determine the cannula diameter corresponding to the cannula position according to the correspondence by obtaining the preset cannula position of the extracorporeal circulation device.

Of course, the measured vessel size may also be used to determine the cannula diameter. For example, the processor 10 determines the cannula diameter according to the size of the target blood vessel, in this embodiment, the size of the target blood vessel obtained in step 1 includes the diameter of the target blood vessel, the memory stores the preset correspondence between different blood vessel diameters and the cannula diameter, and the processor 10 obtains the diameter of the target blood vessel to determine the cannula diameter corresponding to the diameter of the target blood vessel according to the correspondence. The diameter of the cannula is determined by adopting the diameter of the blood vessel, so that the cannula is more accurate. Of course, in some embodiments, the processor 10 may also combine the preset cannula position and the target vessel size to determine the cannula diameter, that is, combine the two methods to verify each other, so as to improve accuracy.

Because the vessel length at various locations of the body is also of a range, the processor 10 can determine the cannula length based on a predetermined cannula position. For example, the memory stores preset correspondence between different cannula positions and cannula lengths, and the processor 10 obtains the preset cannula positions of the extracorporeal circulation apparatus to determine the cannula lengths corresponding to the cannula positions according to the correspondence.

The processor 10 may also determine the cannula length based on preset patient information. Wherein the patient information includes at least one of a patient type (e.g., adult, child), a height, and a weight, the embodiment is described by taking the above three examples, and generally the higher the height, the longer the cannula length, the heavier the weight, and the longer the cannula length. Specifically, the memory stores: the corresponding relationship between different preset patient types and the length of the intubation tube, the corresponding relationship between different heights and the length of the intubation tube, and the corresponding relationship between different weights and the length of the intubation tube can be determined by the processor 10 according to the three corresponding relationships by obtaining preset patient information. Of course, if the patient information includes only a portion of the patient type, height, and weight, the processor may determine the corresponding cannula length based on the correspondence of the patient information.

Of course, the processor 10 may also combine the preset cannula position and the preset patient information to determine the cannula length, i.e. combine the two methods and mutually verify to improve the accuracy.

There are various techniques for extracorporeal circulation, and there are various corresponding extracorporeal circulation apparatuses, such as an artificial heart-lung machine, an extracorporeal membrane lung oxygenation (Extracorporeal Membrane Oxygenation, ECMO) apparatus, etc., and this embodiment will be described by taking an extracorporeal membrane lung oxygenation apparatus as an example.

The manufacturer type of the existing extracorporeal circulation apparatus on the market, the type of cannula supported by the extracorporeal circulation apparatus produced by each manufacturer, the applicable vessel type (arterial or venous), the cannula diameter, the cannula length and the patient type of each cannula type are also known, and therefore, these information can be collected and stored in advance in a memory. The processor 10 matches in the memory according to the manufacturer type of the extracorporeal circulation device, the applicable blood vessel type of extracorporeal circulation, the cannula diameter and the cannula length, and then the target cannula model corresponding to the target blood vessel can be matched; for example, all cannula models supported by the extracorporeal circulation device are matched according to manufacturer types of the extracorporeal circulation device, and then target cannula models are selected from all cannula models according to applicable blood vessel types, cannula diameters and cannula lengths of the extracorporeal circulation device.

Step 4, the processor 10 displays the target cannula model through the display 320. As shown in fig. 3, the circulation mode is a vein-to-vein mode, so that the target cannulation model of the blood drawing vessel and the blood return vessel shown in the figure is vfr 22. If the preset circulatory mode is the venous-to-arterial mode, the processor 10 displays the target cannulation model of the blood-drawing vessel and the target cannulation model of the blood-return vessel via the display 320.

The processor 10 may also display the size of the target vessel and optionally an ultrasound image of the target vessel via the display 320. For example, the processor 10 may display an ultrasound image B of a selected target vessel (a blood-drawing vessel or a blood-return vessel) and a diameter C of the target vessel through the display 320 based on a user's selected operation, as shown in fig. 3.

In the embodiment, the information setting area A, the ultrasonic image, the blood vessel diameter of the target blood vessel in the ultrasonic image and the monitoring data of vital signs are displayed on the same screen, so that a doctor can monitor a patient conveniently, and the doctor can grasp the information of extracorporeal circulation conveniently.

The method shown in fig. 2 may be triggered automatically, e.g. the monitoring device typically has an extracorporeal circulation monitoring mode, which is a monitoring mode adapted to extracorporeal circulation, and the monitoring data of extracorporeal circulation is displayed in addition to the monitoring data of conventional vital signs. In this embodiment, the processor 10 receives an instruction for starting the extracorporeal circulation monitoring mode, and in response to the instruction, the method shown in fig. 2 is executed, i.e., step 1 is started. Therefore, according to the monitoring device provided by the invention, a doctor prepares to support extracorporeal circulation for a patient, and after the monitoring mode of the monitoring device is switched to the extracorporeal circulation monitoring mode, the monitoring device can recommend the model of the intubation of the blood drawing blood vessel and the blood return blood vessel only by inputting the circulation mode and/or the intubation position, so that the doctor does not need to do complex preparation work, and the working efficiency is improved. If the doctor feels that the recommended intubation model is not problematic, the doctor can select the intubation of the recommended intubation model to place the intubation for the patient, and then extracorporeal circulation support is provided for the patient through extracorporeal circulation equipment.

After the patient starts the extracorporeal circulation, the processor 10 may further acquire at least one of an actual circulation pattern, an actual cannula position and actual patient information from the extracorporeal circulation apparatus, and in this embodiment, acquire the three kinds of information correspondingly.

The processor 10 judges whether the actual circulation mode is the same as the preset circulation mode, if so, the processor indicates that the problem is solved, and the processor does not process the problem; if the actual circulation mode is different from the preset circulation mode, corresponding alarm information is sent out through the display 320 to prompt a doctor; the model of the target cannula can be updated and displayed according to the actual circulation mode, and the function of prompting a doctor can be achieved.

The processor 10 judges whether the actual cannula position is the same as the preset cannula position, if so, the instruction is that the problem is solved, and the processing is not performed; if the actual cannula position is different from the preset cannula position, a corresponding alarm message is sent out through the display 320 to prompt a doctor; the model of the target cannula can be updated and displayed according to the actual cannula position, and the function of prompting a doctor can be achieved.

The processor 10 judges whether the actual patient information is the same as the preset patient information, if so, the processor indicates that the patient has no problem and does not process the patient information; if the actual patient information is different from the preset patient information, corresponding alarm information is sent out through the display 320 to prompt a doctor; the model of the target cannula can be updated and displayed according to the actual patient information, and the function of prompting a doctor can be achieved.
