Description

[0001] Implementation

[0002] This invention relates to medical devices and non-transitory computer-readable storage media.

[0003] Many medical devices are electrical devices that require electrical energy to perform medical functions. In some cases, such medical devices are battery powered and transportable during use, and may also have a main power supply that can be connected to a power outlet, etc.

[0004] Taking infusion pumps used in hospitals as an example, battery-powered infusion pumps are often advantageous when patients receiving infusions from the pump need to move from one room to another while maintaining the infusion, or when there is an unexpected disconnection of the main power cable, power outage, or other unforeseen circumstances.

[0005] In a home care setting, patients desire to live as normal a life as possible, and many are active during infusions or nutritional therapy. This includes activities at home, as well as the ability to visit family, shop, travel, and so on.

[0006] During transport, infusions and / or nutrition may also be delivered, for example, in airplanes, buses, trains, etc., where there may be a lack of power supply or inconvenience in connecting to a power supply.

[0007] For example, in the described scenario, the longer the battery life, the more flexible the processing of the corresponding medical device. Therefore, such a medical device can be equipped with a relatively large battery that allows for a long battery life. However, a drawback is that such a large battery also results in a greater weight, which may be detrimental to the processing of the corresponding medical device, at least in some cases.

[0008] The purpose of this invention is to improve the handling of medical devices.

[0009] This objective is achieved by a medical device having the features described in claim 1.

[0010] Therefore, the medical device includes at least one power-consuming unit and a controller. The controller is configured to receive parameters indicating the drug type and / or treatment type, and to select a mode among a predefined high-power mode and at least one predefined low-power mode based on the received parameters, wherein the at least one power-consuming unit consumes less power when operating in at least one low-power mode than when operating in a high-power mode. The controller is also configured to control the power-consuming unit to operate in the selected mode.

[0011] The technical solution adopted in this invention is to reduce power consumption by differentiating whether medication and / or treatment are in power-saving mode without increasing battery size, thereby improving device autonomy and processing efficiency. As an example, in some cases (e.g., during critical care of a patient), turning off the screen after a predetermined time may be unacceptable, but may be acceptable during another treatment. Therefore, the described solution allows for power savings in many situations, thereby improving battery life.

[0012] Medical devices can be infusion pumps. Infusion pumps particularly benefit from the solutions described above because increased battery life also improves the safety of the infusion process, such as in the event of a power outage. Infusion pumps can be used for a variety of different treatments, some of which are critical care and others are non-critical care.

[0013] The medical device may also include a power input terminal, wherein at least one power-consuming unit is configured to be powered via the power input terminal when connected to a main power source. The medical device also includes an internal power supply, wherein at least one power-consuming unit is configured to be powered by the internal power supply when the power input terminal is disconnected from the main power source. The controller may be configured to select a high-power mode when at least one power-consuming unit is powered via the power input terminal, and to select at least one low-power mode when at least one power-consuming unit is powered by the internal power supply (and depending on parameters). This can improve performance while improving battery life. Alternatively or additionally, the controller may be configured to select at least one low-power mode when the internal power supply is charging via the power input terminal. This reduces charging time.

[0014] The medical device may also include a memory for a storage library. The library may include multiple entries, each assigning a drug type and / or treatment type to a corresponding indicator. The controller can be configured to read the drug type and / or treatment type indicators assigned to received parameters from the library and use the indicators to select a mode. This allows for improved selection of high-power or low-power modes.

[0015] Medical devices may include interfaces configured for inputting parameters to facilitate use. Users (e.g., medical personnel) can input parameters to set up the infusion process. In addition to setting up the infusion process (e.g., having a specific flow rate, duration, etc.), a high-power mode or a low-power mode can be automatically selected based on the parameters.

[0016] As an example, at least one power-consuming unit may include a display. At least one low-power mode may define the operation of the display. Since displays typically consume a relatively large amount of energy, the energy-saving potential is correspondingly high.

[0017] Compared to the high-power mode, the display can operate with reduced brightness in at least one low-power mode and / or be turned off after a predetermined time following the activation of at least one low-power mode. Alternatively or additionally, compared to the high-power mode, the display's backlight can be turned off or dimmed in at least one low-power mode. This effectively saves energy.

[0018] As another example, at least one power-consuming unit may include a fluid pumping mechanism. At least one low-power mode may define the operation of the fluid pumping mechanism. Fluid pumping has significant energy-saving potential that has not yet been fully utilized.

[0019] For example, the fluid pumping mechanism alternately turns on and off in at least one low-power mode. This saves energy and extends battery life. During the on phase of the fluid pumping mechanism, it can operate at a higher flow rate than in high-power mode. Therefore, the same amount of liquid can be applied with lower total energy consumption over the same time period.

[0020] At least one power-consuming unit may alternatively or additionally include a sensor. At least one low-power mode may define the operation of the sensor. The sensor and its readings consume a relatively large amount of energy.

[0021] For example, compared to the high-power mode, the sensor operates at a reduced measurement frequency in at least one low-power mode. That is, the sensor can be used less over the same period of time, thus saving energy.

[0022] In one example, the sensor is either an air detection sensor or a blockage detection sensor. An air detection sensor is configured to detect air, such as air bubbles, in the delivery line connected to the medical device. A blockage detection sensor is configured to detect blockages in the delivery line. In critical care, it may be necessary to ensure the absence of air and / or blockages very frequently, while in non-critical care or other applications, much less frequent detection may suffice.

[0023] As another example, at least one power-consuming unit may include a communication interface, particularly a wireless communication interface. At least one low-power mode can define the operation of the wireless communication interface. This also effectively saves energy.

[0024] For example, compared to high-power mode, the wireless communication interface operates at a reduced data exchange frequency in at least one low-power mode. Data can be transmitted only after longer time intervals. For example, updated status information may not be provided frequently. This saves energy in transmitting and processing data.

[0025] According to one aspect, a computer-readable storage medium is provided, comprising instructions that, when executed by a controller of a medical device (e.g., an infusion pump), the medical device including at least one power-consuming unit, cause the controller to perform the following steps: receiving parameters indicating drug type and / or treatment type; selecting a mode among a predefined high-power mode and at least one predefined low-power mode based on the received parameters, wherein the at least one power-consuming unit consumes less power when operating in the at least one low-power mode than when operating in the high-power mode; and controlling the power-consuming unit to operate in the selected mode.

[0026] For an overview of the advantages of computer-readable storage media, refer to the discussion above regarding medical devices.

[0027] The basic concept of the invention will then be described in more detail with reference to the embodiments shown in the accompanying drawings. In this document:

[0028] Figure 1 A medical device in the form of an infusion pump for administering fluids to a patient is shown;

[0029] Figure 2 An infusion system with various medical devices is shown;

[0030] Figure 3 It shows Figure 1 Other components of the medical device; and

[0031] Figure 4 It shows the result of Figure 1 The various operations performed by the medical device.

[0032] Subsequently, a medical device will be described in particular. The embodiments described herein should not be construed as limiting the scope of the invention.

[0033] Figure 1 A medical device 1A is shown. The medical device 1A is configured to perform medical functions. For example, the medical device 1A is configured to provide medical treatment and / or medical diagnosis to a patient.

[0034] Medical device 1A is an electrical device. Medical device 1A includes at least one power-consuming unit. In this example, medical device 1A includes a plurality of power-consuming units 10A to 10D. Each of the power-consuming units 10A to 10D uses electrical energy to perform a function.

[0035] The power-consuming unit 10A of the medical device 1A includes a display 100. For ease of reference only, this power-consuming unit 10A is referred to as the first power-consuming unit 10A. The display (e.g., to name just a few examples, a TFT, LC, LED, MicroLED, or OLED display) is configured to display information. In this example, the display 100 is configured to visualize information related to the medical functions of the medical device 1A, such as status information, possible errors, etc.

[0036] according to Figure 1 For example, medical device 1A is an infusion pump. It is worth noting that... Figure 1 The infusion pump is an injection pump; however, this is merely exemplary, and the infusion pump can also be, for example, a volumetric pump. Similarly, medical device 1A is not necessarily an infusion pump and can be other types of medical devices.

[0037] Medical device 1A includes a housing 15 and a receiving portion 150 disposed on the housing 15 to house a syringe 3 (or other means for storing and / or guiding fluid). The fluid container 30 of the syringe 3 is connected to a delivery line 4 via a connector 32. In this example, the fluid container 30 has a cylindrical shape. The delivery line 4 is connected to or can be connected to a patient for administering fluid to the patient, for example, via a catheter. To mount the syringe 3 onto the receiving portion 150 of medical device 1A, the fluid container 30 of the syringe 3 is placed within the receiving portion 150 and mechanically connected to the housing 15 by means of a retaining device 151 of the housing 15. The syringe 3 is secured within the receiving portion 150 by means of the retaining device 151, for example, a releasable clamping element, such that the fluid container 30 of the syringe 3 is held in the proper position on the receiving portion 150.

[0038] To deliver (medical) fluid contained in fluid container 30, the piston 31 of syringe 3 can be pushed into fluid container 30 in a pushing direction. For this purpose, medical device 1A includes a (second) power-consuming unit 10B. The second power-consuming unit 10B includes a fluid pumping mechanism 101A having a pushing device movably arranged on housing 15 and operatively connected to an electrically driven device of medical device 1A. To set up operation of medical device 1A, syringe 3 is mounted and the pushing device is moved (manually and / or electrically) toward the piston head of piston 31 until the pushing device abuts against the piston head. To perform the infusion process, the pushing device is then moved (electrically using the electrically driven device) in a pushing direction to move piston 31 into fluid container 30 for delivering fluid contained in fluid container 30 to the patient via delivery line 4.

[0039] The medical device 1A also includes a user interface 14 for inputting commands. The user interface 14 includes multiple buttons 140. However, various other devices for inputting information are also conceivable, such as touchscreens or communication-connected devices like keyboards or mice.

[0040] Medical device 1A also includes power consumption units 1C and 1D, which will be referred to below. Figure 3 To provide a more detailed description.

[0041] In addition, the medical device 1A includes a power input terminal 12 having a plug 120 connected to the housing 15 via a cable 121. When the plug 120 is electrically connected to the main power outlet 2, the medical device 1A is powered via the plug 120 and the cable 121.

[0042] Figure 2 An infusion system 5 for administering one or more medications to a patient is shown. A control device 50 and several medical devices 1B, 1C, including an infusion pump, are shown by way of example of the infusion system 5. As shown, the control device 50 and the infusion pump are mounted on a support 51, but this is only an example. The infusion pump (and control device 50) are arranged vertically along a rod of the support 51.

[0043] The bracket 15 provides several slots for mounting medical devices (e.g., infusion pumps). It is worth noting that... Figure 2 Some of the medical devices 1B are infusion pumps (similar to...) Figure 1 The medical device 1A includes a fluid pumping mechanism 101A as described above. Another medical device 1C is a volumetric pump connected via tubing to an infusion bag or other container holding medical fluids. The volumetric pump medical device 1C includes a fluid pumping mechanism 101B that applies pressure to the tubing to deliver the fluid contained therein. It is noteworthy that the infusion system 5 may include more or fewer infusion pumps and / or volumetric pumps and / or other medical devices.

[0044] The bracket 15 provides power to the medical devices 1B and 1C. Alternatively, the medical devices 1B and 1C can be directly connected to the main power supply 2. The bracket 15 can be connected to the main power supply 2 via cable 121 and plug 120.

[0045] Figure 1 and Figure 2 Each of the medical devices 1A to 1C shown is capable of operating in a high-power mode (HPM) and one or more low-power modes (LPM), as will be referred to below. Figure 3 and Figure 4 Further detailed description.

[0046] Figure 3Shown in the form of function blocks Figure 1 Other components of the medical device 1A are shown. Various power-consuming units 10A to 10D are shown, as well as a controller 11, a power input terminal 12, an internal power supply 13, and a user interface 14.

[0047] Figure 2 The medical devices 1B and 1C also include various power-consuming units, such as... Figure 3 The power-consuming units 10A to 10D shown, and as... Figure 3 The controller 11, power input terminal 12, and internal power supply 13 are shown. Figure 2 Medical devices 1B and 1C may also include, for example Figure 3 User interface 14 is shown.

[0048] The first power-consuming unit 10A includes the display 100 as described above. The second power-consuming unit 10B includes a fluid pumping mechanism 101A (or fluid pumping mechanism 101B in the case of a positive displacement pump). The fluid pumping mechanism 101A includes an electric drive device 104 having an electric motor.

[0049] (Third) The power-consuming unit 10C includes at least one sensor 102, and in this example includes multiple sensors 102. Specifically, the medical device 1A includes an air sensor for detecting air in the connected delivery line 4 and a blockage sensor for detecting blockage in the connected delivery line 4. The medical device 1A also includes a pressure sensor for measuring the pressure in the delivery line 4.

[0050] (Fourth) The power-consuming unit 10D includes a communication interface, which typically includes a wired communication interface and / or a wireless communication interface. In this example, the fourth power-consuming unit 10D includes a wireless communication interface 103.

[0051] Controller 11 includes memory 110 and processor assembly 111. Memory 110 is a computer-readable medium. Memory 110 in this example is non-volatile. Memory 110 may include one or more memory chips. Memory 110 of controller 11 may optionally also include volatile memory. Memory 110 stores instructions 12. In this example, memory 11 also stores a library 113; however, library 113 may also be stored in the memory of another device communicatively coupled to controller 11.

[0052] Processor component 111 includes one or more processors. Instructions 112 stored in memory 110 are executable by processor component 111. When instructions 112 are executed by processor component 111, they cause processor component 111 to perform the following... Figure 4 More detailed steps.

[0053] The controller 11 controls the operation of power-consuming units 10A to 10D. The controller 11 can be located inside or outside the housing 15. The controller 11 can also be located in the control device 50 (and the user interface 14).

[0054] Library 113 is adapted to store multiple entries 114. Each entry 114 is associated with one of a variety of drugs and / or one of a variety of treatment types. Each entry 114 includes a drug type entry and / or a treatment type entry. The drug type entry indicates the drug type. The treatment type entry indicates the treatment type. For example, the drug type entry (or treatment type entry) includes a serial number, name, or other unique identifier. Each entry 114 also includes an indicator 115. Each entry 114 assigns the drug type and / or treatment type to a corresponding indicator 115.

[0055] The power input terminal 12 includes a power supply device 122. The power supply device 122 is configured to receive power from the main power supply 2 (via plug 120 and cable 121 and / or via bracket 15). In this example, the power supply device 122 is also configured to convert the received power from AC to DC and from a higher voltage to a lower voltage (this is not necessary if the received power is available for use by the power-consuming unit).

[0056] The power supply device 122 provides power to the power-consuming units 10A to 10D. The power-consuming units 10A to 10D can operate under the power provided by the power supply device 122.

[0057] The internal power supply 13 includes a battery 130, such as a lithium-ion battery. The battery 130 stores electrical energy. The internal power supply 13 is configured to provide power to the power-consuming units 10A to 10D. For example, when the main power supply 2 is unavailable or disconnected for other reasons, the power-consuming units 10A to 10D can operate under the power provided by the internal power supply 13.

[0058] If the power input terminal 12 is connected to the main power supply 2, the power supply device 122 can charge the battery 130.

[0059] Battery 130 has a limited capacity. The capacity of battery 130 limits the maximum possible battery life of medical device 1A when it does not receive power via power input 12. To extend battery life (and, for example, to establish an infusion process), controller 11 is configured to receive parameter P. Parameter P indicates the drug type and / or treatment type. Parameter P can be input via user interface 14 and / or via another interface (e.g., wireless communication interface 103).

[0060] Controller 11 is also configured to select mode HPM or LPM from a predefined high-power mode HPM and at least one predefined low-power mode LPM based on the received parameter P (see [link]). Figure 4 At least one power-consuming unit 10A to 10D consumes less power when operating in at least one low-power mode LPM than when operating in a high-power mode HPM. The controller 11 is configured to read from a library 113 an indicator 115 assigned to the drug type and / or treatment type indicated by the received parameter P, and to use the indicator 115 to select mode HPM or LPM.

[0061] The controller 11 is also configured to control power-consuming units 10A to 10D to operate in the selected HPM or LPM mode.

[0062] Controller 11 receives parameter P, reads entry 114 corresponding to parameter P, and reads indicator 115 from entry 114. If indicator 115 indicates high power mode HPM, controller 11 controls power-consuming units 10A to 10D according to high power mode HPM. If indicator 115 indicates low power mode LPM (or one of several different low power mode LPMs), controller 11 controls power-consuming units 10A to 10D according to the indicated low power mode LPM.

[0063] Therefore, for a specific drug type and / or for a specific treatment type, a low-power mode LPM (or one of several different low-power mode LPMs) is indicated by indicator 115. For example, antibiotics are often administered using an intermittent mode (where short-duration infusions and pauses are alternated), and the importance lies in the dose delivered.

[0064] For another type of medication and / or treatment, high-power mode HPM is indicated by indicator 115 of the corresponding entry 114 in library 113, such as catecholamine delivery (e.g., in this case, parameter P indicates catecholamine as a medication type and / or catecholamine delivery as a treatment type). Catecholamine delivery typically requires very stable drug delivery to maintain the patient's hemodynamic stability. Therefore, the pharmacist responsible for library 113 can adjust the pump operation based on the severity of the medication or the administration pattern.

[0065] A first low-power mode (LPM) can define the operation of the display 100. Specifically, at least one low-power mode (LMP) defines the display 100 to operate with a lower brightness compared to a high-power mode. Furthermore, the low-power mode (LPM) defines the brightness of the display 100 to decrease after a predetermined time (e.g., when at least one low-power mode is activated and / or after the last input to the user interface 14 or after other predefined events). The low-power mode (LPM) also defines the brightness of the display 100 to decrease during a predetermined time period (e.g., nighttime). The low-power mode (LPM) can also define the display 100 to turn off after a set time. The user can turn the display 100 back on at any time by touching the touch panel or button 140. The display 100 is also turned on when the controller 11 issues an alarm to warn the user or patient (e.g., in the event of air or obstruction). Optionally, the medical device 1A includes an auxiliary low-consumption display (e.g., an e-ink display) or other visual indicators to continue providing infusion-related instructions when the (main) display 100 is off.

[0066] The second low-power mode LPM defines the operation of fluid pumping mechanisms 101A and 101B, wherein fluid pumping mechanisms 101A and 101B are alternately turned on and off in the second low-power mode. In high-power mode, pumping is set to continuous pumping for treatment requiring continuous drug delivery, such as catecholamines, and is typically given to critically ill patients with limited mobility. In the second low-power mode LPM, pumping is set to pulsed operation, for example, when pharmacokinetic or pharmacodynamic properties make alternating drug delivery between pumping and pause times clinically acceptable, such as when delivering enteral nutrition in the stomach. Pulsed operation can be performed using a switch on the motor power supply device (operated by controller 11) to cause fluid pumping mechanisms 101A and 101B to push volumes, and to turn off the motor power supply device, etc., once the pumping mechanism is in a stable state. That is, not only the motor can be stopped, but also its power supply device and / or electronics can be turned off.

[0067] The third low-power mode (LPM) defines the operation of sensor 102. Specifically, compared to the high-power mode (HPM), at least one of the sensors 102 operates at a reduced measurement frequency in the third low-power mode (LPM). For example, for critical drug delivery, it is preferred to detect conditions such as obstruction as quickly as possible; therefore, in the high-power mode (HPM), sensor 102 is read out frequently, for example at the maximum frequency. For other therapies, lower responsiveness is acceptable. The third low-power mode (LPM) reduces the frequency of sensor readouts and data processing (compared to the high-power mode (HPM)). As an example, when the fluid pumping mechanisms 101A, 101B are in a steady state (e.g., not pumping), the obstruction sensor (or other sensor) can be turned off in the third low-power mode (LPM) and turned on when the fluid pumping mechanisms 101A, 101B are currently pushing a fluid volume. Air detection is critical when the medical device 1A delivers fluid into a vein. Therefore, the high-power mode (HPM) is set when the treatment type indicates infusion into a vein, or the low-power mode (LMP) is set so that the air sensor does not operate in low-power operation. On the other hand, air delivery may be more acceptable for patients receiving enteral nutrition via the stomach. Therefore, in this case, the air sensor is turned off or reads at a lower frequency in the third low-power mode (LPM) compared to the high-power mode (HPM). Regarding pressure measurement, the pressure sensor and pressure data processing can be adjusted accordingly, depending on whether the earliest detection of pressure outside a predetermined range is prioritized, or whether a longer detection time is allowed to prioritize battery life. Therefore, the pressure sensor readout frequency may be lower in the third low-power mode (LPM) compared to the high-power mode (HPM).

[0068] The fourth low-power mode (LPM) defines the operation of the wireless communication interface 103 (or other communication interface), wherein the wireless communication interface 103 (or other communication interface) operates at a reduced data exchange frequency compared to the high-power mode (HPM). The required data exchange frequency may vary depending on the severity of the treatment and / or delivery of medication, and can therefore be adjusted based on whether data exchange responsiveness must be prioritized, or whether battery life of 130 can be prioritized. The user interface 14 can also be considered a power-consuming unit and operate in either the high-power mode (HPM) or the low-power mode (LPM) if it consumes power. For example, if the user interface 14 includes a touchscreen, the touchscreen can be turned off in the low-power mode (LPM). It can then be turned on upon the occurrence of a predefined event (e.g., pressing button 140, an alarm, etc.).

[0069] At least one of the following: a fifth low-power mode LPM combination, namely, a first low-power mode LPM, a second low-power mode LPM, a third low-power mode LPM, and a fourth low-power mode LPM, particularly all of the first low-power mode LPM, the second low-power mode LPM, the third low-power mode LPM, and the fourth low-power mode LPM.

[0070] Furthermore, the selection of high-power mode (HPM) or low-power mode (LPM) can depend on other factors (i.e., in addition to parameter P). For example, controller 11 is configured to select high-power mode (HPM) when at least one power-consuming unit 10A to 10D is powered via power input terminal 12. Controller 11 can also be configured to select high-power mode (HPM) or low-power mode (LPM) based on input parameter P when at least one power-consuming unit 10A to 10D is powered by internal power supply 13.

[0071] Indicator 115 can be configured to provide an indication that a high-power mode HPM or a specific low-power mode LPM will be applied, and that such application is mandatory. However, indicator 115 may also be allowed to assume a preference value, such as a high preference for high-power mode HPM, while also allowing the application of low-power mode LPM, for example, when necessary or appropriate for other reasons.

[0072] The controller 11 can also be configured to select a low-power mode (LPM) when the internal power supply 13 is charging via the power input 12. For example, if the indicator 115 corresponding to the input parameter P indicates a preference for using the high-power mode (HPM), but the low-power mode (LPM) can also be selected, the controller 11 can then determine the mode based on whether the battery 130 is currently charging. Similarly, if the indicator 115 corresponding to the input parameter P indicates a preference for using the high-power mode (HPM), but the low-power mode (LPM) can also be selected, the controller 11 can determine the mode based on the battery 130's state of charge (SOC, a value from 0% to 100%) and / or remaining battery life. For example, if the SOC and / or remaining battery life are above a given threshold, the high-power mode (HPM) can be selected; otherwise, the low-power mode (LPM) can be selected.

[0073] Figure 4 The operating steps performed by medical device 1A (or one of medical devices 1B or 1C) are shown.

[0074] At step S1, controller 11 receives parameter P indicating the drug type and / or treatment type. For example, parameter P is received by selecting from a list using user interface 14.

[0075] In step S2, the controller selects either mode HPM or LPM from among a predefined high-power mode HPM and one or more predefined low-power modes LPM (e.g., the first to fifth low-power modes mentioned above) based on the received parameter P. The power-consuming units 10A to 10D of the medical device 1A consume less power when operating in the corresponding low-power mode LPM than when operating in the high-power mode HPM.

[0076] If controller 11 selects high power mode HPM ( Figure 4 If the left arm is selected (in the middle), then controller 11 continues to step S3A and controls power-consuming unit 10A to 10D to operate in the selected high-power mode HPM. If controller 11 selects low-power mode LPM ( Figure 4 If the right arm is in the middle, then the controller 11 continues to step S3B and controls the power-consuming units 10A to 10D to operate in the selected low-power mode LPM.

[0077] The memory 110 is a non-transitory computer-readable storage medium on which computer-executable instructions 112 are stored, which, when executed by the controller 11 (more specifically, the processor component 111 of the controller 11) of the medical devices 1A to 1C including power-consuming units 10A to 10D, cause the controller 11 (more specifically, the processor component 111) to perform the above steps.

[0078] The concept of the present invention is not limited to the above-described embodiments, but can be implemented in different ways.
