In an embodiment of the present disclosure, the end user is a patient. or the administrator of an enteral feeding pump. The pump 1 is equipped with a flow monitor that can detect and identify the condition of the supply set 7 loaded into the pump. As used herein, the term "loading" refers to a system that is capable of carrying out a variety of functions, including, but not limited to, a single camera. The term is used when the feeding set 7 is engaged with the pump 1 so that the feeding set delivers fluid to the patient. This means that the pump is ready to be actuated to deliver the

[0031] In the illustrated embodiment, the cassette 5 is removably received in a cassette recess 8 of the housing 3. (FIG. 3). The term "housing" as used herein is not limited to However, multiple components, including multi-part structures and structures that do not enclose or house the working components of pump 1, are also possible. It will be appreciated that many forms of support structure (not shown) may be included. Various aspects and features may be implemented without the recess 8. The pump 1 may also include a housing 3 is provided with a display screen 9 capable of displaying information regarding the status and operation of the pump. One or more buttons 11 may be provided adjacent the display screen 9 to control and operate the pump. 1, one or more light emitting devices (e.g., An LED ("LED") 13 can provide status information for the pump. So, a light-emitting element is any device that transmits light, such as an optical fiber or a light-emitting diode. For example, the LED 13 may be configured to indicate proper or improper functionality of the pump 1. Further, for example, the LED may also indicate that fluid is being properly pumped through the supply set 7. It can show whether the water is flowing properly or improperly. The housing is supported by legs (not shown) at the base, and the display screen 9 is easily viewable by the user. can be tilted slightly upwards.

[0032] Display screen 9 is part of a front panel (generally designated 19) of housing 3. The pump 1 may further include: A pump, generally designated 23, is provided with a pump motor 27 (FIG. 4) connected to the rotor shaft. The pump unit may include a housing 3 for supplying power to the pump motor. The battery (not shown) can be received in the battery compartment. Additionally, the power source is used to drive one or more prime movers that drive the pump units via the rotor shaft. Another example of a pump with a rotor shaft is described in U.S. Pat. No. 2020 / 0352827, the entire disclosure of which is hereby incorporated by reference. is incorporated into the book.

[0033] The pump unit 23 includes a rotor (generally indicated at 37) which may be coupled to a rotor shaft. The rotor 37 may have an inner disk 39, an outer disk 41, and a rotor 37. The device may include a plurality of sensors 43 (four are preferred, but only two are shown). The inner disk 39 and the outer disk 41 are preferably spaced apart from each other and in parallel planes. The roller 43 can rotate about the shared axis of the disks 39 and 41. It is mounted between an inner disc 39 and an outer disc 41 for planetary rotation. Each roller 43 also has its own roller that may be parallel to the shared axis of the disks 39, 41. Disk 39 is rotated relative to disks 39, 41 about a vertical axis (FIGS. 2 and 3). , 41. A roller 43 rotates about the axis of the disks 39, 41. As the feed set 7 is being fed, the rollers 43 engage the tubes 45 (FIG. 2) of the feed set 7, causing the feed set to rotate. 5 and is provided by peristaltic engagement when the cassette is attached to the housing 3. The fluid is delivered to the patient through the feeding set. Other numbers of rollers are envisioned and may be implemented. For example, but not limited to, five or six Rollers may also be used.

[0034] Rollers 43 are adapted to engage the feeding set 7 to move fluid through the feeding set. In the illustrated embodiment, the pump motor 27, the rotor shaft, and the rotor 37 are generally These components may be considered "pumping equipment." It is understood that peristaltic pumps using mechanisms other than rollers may be included within the scope of the present disclosure. However, other pumping devices (e.g., non-rotating devices) are also contemplated. .

[0035] As used herein, the portion of the tube 77 of the feed set 7 that leads to the rotor 37 is referred to as “ 37 to the patient is referred to as "downstream." The rotation of the rotor 37 compresses the tube 45 of the feeding set 7, causing the fluid (e.g., nutrients) to flow through the tube 45. The fluid is driven from the upstream side of the feeding set to the downstream side toward the patient. Although shown, other configurations of supply sets or other types of pump sets (not shown) may be used. It can be used.

[0036] 2 to 4, the monitoring system 6 (FIG. 4) monitors the supply set 7 loaded in the device. For example, the state of the supply set 7 can be determined by detecting the Check the flow of liquid, whether the set is properly attached to the pump, whether there is a blockage, or may relate to other aspects of the feeding set or its operation, for example, the flow of liquid through the set The flow may include a lack of or inadequate flow of liquid through the set. If the set is installed improperly on the pump, fluid may not flow properly through the set. In addition, the tube may become damaged if, for example, the set is improperly attached to the pump. There may be a blockage in the tube.

[0037] The pump 1 may further include a microprocessor 62 in communication with a sensor 64. Microprocessor 62 controls and manages the operation of the various components of pump 1. A software subsystem 66 is operatively coupled to the microprocessor 62. and operatively coupled to a monitoring system 6 for detecting the condition of the pump 1 and the supply set 7. In the described embodiment, the flow monitoring system provides a means for identifying the system 6, software subsystem 66, pump electronics 68, microprocessor 62 and It should be understood that the memory 70 may be broadly considered to be a "control circuit." Each of these components may be individually considered a "control circuit." Additionally, other types of A control circuit for the 1000V power supply may be used. As will be explained below with reference to FIGS. Additionally, the control circuitry may be implemented in conjunction with a variety of components.

[0038] The sensor 64 may include one or more ultrasonic sensors. 1 and configured to detect the presence of fluid and one or more characteristics (e.g., For example, the device may be positioned to detect a fluid blockage in the feeding set. The sensor 64 is disposed in the recess 8 and is connected to the tube 45 when the supply set 7 is loaded into the pump 1. The sensor 64 is adapted to securely receive a portion of the tube of the feeding set 7. To detect the presence of fluid within 45, the tube is provided with an upstream portion and a downstream portion of the tube 45. The sensor track 105 (FIG. 3) may be configured to receive and engage the sensor. The tube 45 is engaged within the sensor track 105 and the remainder of the supply set 7 is pumped. When the monitoring system 6 is engaged with the host 1, the monitoring system 6 may be enabled. For example, the monitoring system 6 may by receipt of an acceptable signal (e.g., an ultrasonic signal) by one or more detectors or receivers. When positive engagement of the tube 45 within the sensor track 105 is identified, the sensor is operationally The sensor 64 can be arranged perpendicular to the direction of the supply set 7. For example, the sensor 64 may be positioned to read horizontally while the supply The set 7 may be arranged to direct the fluid flow vertically. In one embodiment of the present disclosure, the sensor 64 is set at a 90 degree angle to the feed set 7. As will be explained in more detail below 3, the tube 45 of the supply set 7 engaged with the sensor track 105 is read horizontally. Even if the sensor 64 is placed in this way, the position of the tube 45 or the sensor 64 may be shifted, resulting in a loss of understanding. The sensor, as mentioned above, may provide readings that are less than ideal. It may output incorrect information, such as showing the wrong state.

[0039] In one aspect of the present disclosure, the sensors 64 measure the upstream and downstream portions of the tube 45, respectively. a first sensor component 107, 109 for transmitting an ultrasonic signal through the first sensor part a second sensor component 107 configured to receive and detect ultrasonic signals transmitted from the product; , 109. The ultrasonic signal from the first sensor component 107, 109 Upon receiving the signal, the second sensor component 107, 109 detects whether the signal has been received by the second sensor component. Based on the characteristics of the ultrasonic signal transmitted to the microprocessor 62, The first and second sensor components 107 and 109 are each capable of detecting the presence of a fluid. Each sensor may have the same or substantially the same sensor configuration. The sensor elements 107, 109 may be provided with ultrasonic crystals, whereby the respective sensors The component acts as a transmitter to transmit ultrasonic signals, or as a can be operated as a detector for detecting ultrasonic signals. The direction of the wave signal is not limited to a single direction between the sensor components 107 and 109, but may be any direction between the sensor components. It can be oriented in both directions.

[0040] The sensor 64 detects the presence or absence of fluid in the tube to provide a basic indication of the operating condition of the pump 1. The ultrasonic signals sent from the sensor components 107 and 109 can provide an indication of the in response to the presence of fluid in tube 45, compared to the signal when no fluid is present in the tube. Fluid in the tube can cause an increase in the amplitude of the signal. An ultrasonic signal passing through an all-air medium will not generate a signal at the detector. Based on the characteristics of the received ultrasonic signal transmitted to 62, software subsystem 66 determines: It is possible to determine whether or not there is fluid in the supply set 7. Use other types of sensors to measure one or more fluid properties or characteristics, including viscosity The flow monitoring system 6 may also be implemented in a supply The fluid in the supply set and other conditions associated with the supply set may be detected. This can be done.

[0041] 5A-5C, the tube is distorted within the sensor track 105 of FIG. In this case, the signal strength of the ultrasonic sensor "US" may cause errors and inaccurate readings. In one embodiment of the present disclosure, the tube T1 may be a sensor component of the sensor US. 3. The sensor track 105 of FIG. 3 is substantially vertically aligned so as to span the entire width between E and D (FIG. 5A). The sensor components E and D are the emitter and detector, respectively. In this case, the ultrasonic signal S passes through air before or after passing through the tube T1. Therefore, the sensor reading generated by sensor US is Generates an expected output reading / result based on the presence or absence of fluid in the In this aspect of the disclosure, the sensor US is considered to be functioning properly. The US is manufactured so that there are no gaps or air on either side or inside E and D of the sensor US. If gaps or air pockets exist on both sides or inside of E or D, tube T1 will be Even though the sensor US is positioned at a substantially vertical origin in the sensor track 105 of the fluid This can result in false or inaccurate readings about whether a In another aspect of the present disclosure, which will be described in more detail, the present invention provides a method for correcting or adjusting for errors and inaccurate readings. To do this, it is possible to compensate for gaps or air pockets that introduce errors into the readings. .

[0042] In another embodiment of the present disclosure, tubes T2 and / or T3 may be either sensor components E or D. If the sensor is biased towards the saturation point, the sensor readings will be inaccurate, e.g., higher or lower than expected. This may result in erroneous readings. In particular, if tube T2 is connected to sensor U When biased towards the emitter side E of S (Figure 5B), the signal received at detector D is T3 is stronger than when it is biased toward the detector side D of the sensor (Figure 5C). For example, when the tube T3 is biased toward the detector side D of the sensor US, the fluid actually enters the tube. is present, the sensor reading indicates that there is no fluid in the tube (i.e. For example, when tube T3 is biased toward the detector side D, The X reading may then be determined based on the threshold. If the reading X is lower than the threshold Y, the pump will start to pump the flow in tube T3. When it is determined that no body is present and fluid is in fact present, an alarm is issued to the user as described below. This can cost you time, money, and customer trust. , incorrect readings and outputs may be provided. So, for example, when tube T2 is biased toward the emitter side E of sensor US, the sensor reading is The reading may indicate the presence of fluid in the tube (i.e., high signal). For example, when tube T2 is biased towards the emitter side E, the reading of X by sensor US is may be determined. The reading of X may then be compared to a threshold Y. If X is greater than the threshold Y, the pump determines that there is fluid in the tube T2. The wrong approach will cost you time, money, and customer trust. Different readings and less output are possible.

[0043] 4, 6A, and 6B, within pump electronics 68, there are various sensor components. 107 and 109 act as emitters E for transmitting ultrasonic signals S, and which sensor components The detector D is configured to control whether the detector D operates as a detector D for receiving and detecting ultrasonic signals. The pump 1 thus includes one or more switches 72 that are connected to the sensor 64. To optimize the pump set 7, the pump set 7 may be adjusted to fit the orientation and / or dimensions of the tube 45. One or more switches 72 are electrically connected to the sensor 64 to complete an electrical circuit. By reconfiguring the sensor components 107 and 109, a current is selectively applied to one of the components, and the component that is applied with the current is subjected to ultrasonic waves. The emitter E is configured as: Depending on the sensor components 107, 109, the pump 1 may determine which sensor components 107, 109 are being used to maximize signal strength. It is possible to select which sensor component acts as the emitter E and which acts as the detector D. For example, as described below with reference to Figures 13A, 13B, and 13C, Amplifier 1 is connected to emitter E or detector D to identify the higher sensor US reading. Based on switching the sensor components 107, 109 between operation as Two different readings can be obtained in the pump orientation. and the detector are pre-configured so that the tube position or orientation determines the expected sensor reading in a particular situation. Addresses problems that may arise with conventional pumps when changing (e.g., reducing) the price ( 5C). For example, the tube 45 may be inserted into the sensor track 105 as shown in FIG. The left sensor components 107 and 109 may be configured to be biased in the emitter direction. The sensor components 107 and 109 on the right side are pumped so as to function as detectors. When the amplifier electronics 68 are configured, the sensor signal S is transmitted to the sensor path, particularly when the tube 45 is in the sensor path. If pump 1 is calibrated to assume a substantially vertical position across In this case, the signal strength will be lower than expected for the given fluid conditions. To take into account this possible misalignment of the pump 45, the pump 1 is provided with one or more switches 72, the right sensor element acts as an emitter and the left sensor element acts as an emitter. The right sensor components 107 and 109 are energized so that they function as detectors. As a result, the signal strength of the ultrasonic signal S increases, and the tube moves in the vertical direction. In this way, the flow is actually closer to the ideal state where the fluid is directed toward the tube. A low signal may erroneously indicate the absence of fluid in tube 45 when fluid is present. As a result, various conditions can be detected without compromising the accuracy of the detection of the supply set. This allows for a better fit within the sensor track. This reduces the need to squeeze or flatten the tube to allow it to flow. This processing set, which may compromise the integrity, is removed.

[0044] Further, according to another aspect of the present disclosure, the pump 1 is configured such that the sensor US is generated during the manufacturing process. In the case of defects (gaps, air pockets, etc.) present in the emitter or detector, Addressing possible problems with the pump. As mentioned above, the tube is usually directed toward the emitter E. Although a more accurate reading can be obtained when the sensor is tilted toward the sensor, the sensor components 107 and 109 have However, there may be imperfections such as air pockets and / or gaps that result in erroneous readings of the signal S. For example, referring to FIG. 6B, the sensor components 107 and 109 on the left side emit The pump is connected so that the sensor components 107 and 109 on the right side act as detectors. When the electronics 68 of the sensor are set up, the sensor signal S is Pump 1 is calibrated to assume a substantially vertical position across the passage. In this case, it would be expected to have a lower than expected signal strength for the particular fluid condition. However, as noted above, to account for this possible misalignment of tube 45, To do this, pump 1 activates one of one or more switches 72 to activate the right sensor component The sensor on the right acts as an emitter and the sensor on the left acts as a detector. As a result, the signal strength of the ultrasonic signal S is increased. The signal strength is expected to increase and more closely resemble the ideal situation where the tubes are oriented vertically. In one aspect of the present disclosure, the manufacturing process detects defects in the right sensor components 107, 109. , thereby introducing a large error into the signal S, resulting in lower than expected results. Thus, the results of the tube tilted toward the emitter E are usually more consistent with the fluid flow. Although the left sensor component 107, 1 provides higher and more accurate results, in this example, Based on the defect in 09, the left sensor components 107 and 109 act as emitters and the right When the sensor components 107, 109 act as detectors, the system can obtain a better understanding of the readings. This process allows the pump 1 to adjust the tube orientation and provide higher and more accurate results. and the highest resulting reading is selected regardless of the operation / configuration of the sensor components 107, 109. As a result, it is possible to detect different feeding tube conditions without compromising the accuracy of the feeding set detection. In this way, sensor components with various defects can be used. This reduces the need to compress or flatten the tube to get a better fit. This eliminates the process set that could potentially compromise the integrity of the tube. The need for quality control testing of the sensor US to obtain accurate results is reduced.

[0045] In another aspect of the present disclosure, the operation of the pump 1 is sensor-driven to match the position / orientation of the tube 45. To calibrate the sensor 64, a sensor calibration routine is run (e.g., after each power cycle or Commands executed automatically (when a new cassette is plugged in) or initiated by the user For example, referring to FIG. The routine begins after the pump 1 has confirmed that the supply set 7 has been loaded into the pump and / or At the beginning of each dispense cycle, a calibration routine is started. Further actions for this purpose are also envisaged. In a first step 301, a first sensor component 1 07, 109, and the second sensor components 107, 109 on the opposite side of the first sensor component At 303, the strength of the signal detected by the second sensor component is measured. is measured and stored in the memory 70. In 305, the second sensor components 107 and 109 are energized. , sends an ultrasonic signal toward the first sensor component. Next, in 307, the first sensor component 10 7, 109, the strength of the detected signal is measured and stored in memory 70. Then, the strength of the signal at the second sensor component 107, 109 is compared with the strength of the signal at the first sensor component 107, 109. At 311, the sensor component 107, 109 having the strongest signal is compared to the signal strength at during operation of pump 1 to deliver fluid to a patient through a tube; Configure it to operate as a

[0046] Referring to FIG. 8, an ultrasonic sensor according to another embodiment of the present disclosure is generally designated 164. The sensor includes a first and second pair of sensor components 207A, 209A and 207B, 209B. Each sensor pair is configured similarly to the sensor components 107 and 109 described above. Further, the sensor pair includes a sensor track for receiving the upstream and downstream portions of the tube. The first (upper) sensor section can be located either upstream or downstream of the In the pair of products 207A and 209A, the sensor part on the right side acts as an emitter and the sensor part on the left side acts as an emitter. The second (lower) sensor component pair 2 can be configured to operate as a detector. For 07B and 209B, the sensor part on the left acts as an emitter and the sensor part on the right acts as a detector. This allows the sensor components to be configured to operate as emitters / transmitters. No switch is required to switch detector functions. Instead, the pump uses the sensor components Operate both pairs 207A, 209A and 207B, 209B respectively to operate the pump set In every determination of According to one aspect of the present disclosure, the strongest signal is The sensor readings can be determined by comparing them to thresholds and / or to each other. Additionally or alternatively, switching the emitter / detector function between sensor components of a sensor pair. To this end, one or more switches are connected to the sensor component pairs 207A, 209A and 207B, 209 B, respectively.

[0047] 9, a sensor calibration routine may also be performed on the sensor 164. In step 401, the sensor components 207A, 209A of the first sensor pair are energized to emit The ultrasonic signal is directed to the other sensor component 207A, 209A of the pair on the opposite side of the sensor component. At 403, the strength of the signal detected by the detector assembly is measured and stored in the pump memory. At 405, the sensor components 207B, 209B of the second sensor pair are energized to emit The ultrasonic wave is directed to the other sensor component 207B, 209B of the pair on the opposite side of the sensor component. Then, at 407, a signal is sent by the detector assemblies of the second sensor assembly pair 207B, 209B. The strength of the signal detected by the second sensor is measured and stored in the pump memory. The strength of the signal between the first sensor component pair 207A, 209A is At 411, the sensor part pair 207A, 207B having the strongest signal is compared with the signal strength between the sensor part pair 207A, 207B having the strongest signal. 07B and 209A, 209B for delivering fluid to a patient through a tube, The sensor is configured to operate as a control sensor during the operation of the pump. Three or more pairs of sensors are used. It will be understood that it may be possible.

[0048] Referring to FIG. 10, a pump 501 according to another embodiment of the present disclosure includes a pump set. The first part of the sensor component is combined with an ultrasonic sensor to detect the force applied by the body. At least one pair of sensor components 507, a second pair of sensor components 509, and a pressure sensor 530. In one embodiment, the pressure sensor 530 may include one ultrasonic sensor 564. In one embodiment, the pressure sensor 530 is located downstream of the sensor track 505. The pressure sensor 530 is located upstream of the valve 505. The pressure sensor 530 responds to the flow of fluid in the tube. The sensor track 505 is configured to measure the expansion of the tube in the sensor track 505. Fluid flow within the tube can cause the tube to expand a first amount, compressing the pressure sensor 530. However, blockages in the tube can cause the tube to become more and more blocked as the fluid pressure in the tube increases. Therefore, detecting a pressure exceeding the first threshold may cause the tube to expand significantly. detecting a pressure exceeding a second threshold that is higher than the first threshold and that can indicate a flow of fluid within the The pressure sensor 530 also detects the presence of an occlusion in the tube. Also, the presence of a feeding set is detected independently of whether fluid is flowing through the feeding set. Therefore, the pressure sensor 530 can be configured to supply the pump 501 with It is possible to detect that a new battery has been loaded.

[0049] Ultrasonic sensor 564 detects various conditions of the feeding set loaded into pump 501. The first sensor pair 507 is located upstream of the rotor, and the second sensor pair The sensor pair 509 is located downstream of the rotor. The dual sensor system detects upstream blockages, Provides the ability to identify downstream blockages and empty bladder conditions. For example, blockages in the pump rotor If the flow occurs upstream, the fluid will exit the upstream portion of the tube but will continue to exit the downstream portion of the tube. In this case, the pump 501 continues to pump fluid through the second sensor pair 509. The first sensor pair 506 detects fluid, but the second sensor pair 507 does not detect fluid. If the bag is empty, the pump 501 identifies an upstream blockage. In this case, pump 501 first pumps the The pump 501 then detects the fluid at both sensor pairs 507, 509. is detected by the downstream sensor pair 509 but not by the first sensor pair 507 Finally, the pump 501 detects fluid in either sensor pair 507, 509. In this case, an empty bag error may occur. If a downstream blockage occurs, The downstream portion of the probe is enlarged, improving the conductivity of the signal at the second sensor pair 509 through the fluid. In this case, the pump 501 detects a significant increase in the sensor signal in the second sensor pair, which This is interpreted as a downstream occlusion. Thus, the pump 501 detects the occlusion in real time. Has the ability.

[0050] Additionally, pump 501 may be configured to indicate that a supply set is not installed in the pump. To detect a first pressure P1 within a first pressure range measured by the pressure sensor 530. The pump 501 can be configured such that the supply set is attached to the pump, but the flow Measured by pressure sensor 530 to indicate that body is not flowing through the feeding set The pump may be configured to detect a second pressure P2 within a second range defined by the pressure sensor. The pump has a supply set installed and fluid is present in the supply set but not flowing. To indicate this, a third pressure P3 within a third range measured by the pressure sensor 530 is detected. The pump 501 can be configured to output a supply set to the pump. Measured by pressure sensor 530 to indicate that fluid is flowing through the supply set. The pressure sensor 10 may be configured to detect a fourth pressure P4 within a fourth range defined by the pressure sensor 10.

[0051] The pressure P3 of the fluid in the tube and the pressure P4 of the fluid flow are monitored to detect blockages in the tube. For example, it may be possible to determine whether a fluid is delivered through a feeding set. During operation of pump 501 to supply the supply set, the pressure in the supply set rises from the range of P3 to the range of P4. During normal operation of the pump 501, the pump may be operated to deliver fluid through the supply set. When the pump is deactivated, the pressure drops from the P4 range to the P3 range. If present, the pressure will remain in the range of P4 even after pump 501 is stopped. Pressure profiles can occur even when no occlusion is present. This is due to the nature of the fluid flow. The pressure P4 is based on the properties of the tube and the properties of the fluid being pumped through the tube. Therefore, the accuracy of the calculation depends on the concentration of the fluid, its viscosity, the size of the tube, etc. Therefore, the pressure P4 of the fluid flow may change. Depending on the size and / or the degree of penetration, the tube may actually block the flow of fluid through the tube. When not in use, pressure rises to a level indicative of obstruction (i.e., within the P4 range) Additionally, the fluid properties of the nutrient solution flowing through the feeding set may also affect the amount of air bubbles and other Ultrasonic and solid particles can alter the signal reading and result in false indications. This may affect the readings from the sonic sensor 564.

[0052] The pressure sensor 530 can be used in combination with the ultrasonic sensor 564 to After the first indication is made by one, verification of the presence of fluid in the tube and the presence of a closed For example, an ultrasonic sensor 564 can provide verification that a blockage is present. The device may be operable to determine whether or not a fluid is present in the probe. The ultrasonic sensor 564 indicates that fluid is present, such as by a sensor reading exceeding In this case, an initial indication of the fluid in the tube can be made. This initial indication is followed by a pressure reading. The force sensor 530 is operated to measure the force applied by the tube to the pressure sensor. If a pressure reading of P2 or P3 is measured, the pressure sensor 530 The presence of fluid in the tube can be confirmed by ultrasonic sensors. In response to an initial fluid detection by pressure sensor 530 or when pressure sensor 530 detects that fluid is present in the tube, Only after verifying its existence can a corrective message or alert be provided. .

[0053] More specifically, pump 501 is configured to execute a fluid detection routine (FIG. 11). 601, ultrasonic sensor 564 is configured to determine the status of the supply set. The sensor operates by sending an ultrasonic signal through a portion of the tube. If the threshold is exceeded, the pump detects at 603 the first indication that fluid is present in the tube. If the sensor reading is below a predetermined threshold, the pump 501 05 provides an indication that there is no fluid in the tube. If it is determined that fluid is present in the probe, a verification subroutine V is initiated. During the process, at 607, pressure sensor 530 operates to measure force at the downstream portion of the tube. If the measured force exceeds a predetermined threshold, then at 609 the pump detects that there is fluid in the tubing. The pump then alerts you that there is fluid in the tubing. If the measured force is below a predetermined threshold, the force may be read or stored in memory. At 611, the initial fluid detection indication is not acknowledged. The pump resumes the fluid detection routine. or providing an alert that detection of fluid in the tube was not possible. Thus, the pump 501 goes through a series of steps to pump the fluid in the supply set. A first indication of presence and a secondary table using sensor readings from two different sensor types The device is configured to provide indication / confirmation.

[0054] Similarly, detection of an occlusion may be accomplished by first activating pressure sensor 530 to apply force downstream of the tube. This can be done by measuring the force profile consistent with an occlusion. (e.g., pressure rise from range P3 to range P4 during operation of pump 501, pump If the pressure remaining in the P4 range after stopping for a certain period of time is measured, the first blockage is detected. The pump 501 then activates the pressure sensor 530 to detect the initial closure. The readings from the ultrasonic sensor 564 can also provide verification of occlusion detection. If the pressure sensor 53 indicates that the pump 501 is in a closed state, the initial occlusion detection is confirmed. 0 or after confirmation by ultrasonic sensor 564. It can alert the user to a blockage.

[0055] More specifically, pump 501 is configured to execute an occlusion detection routine (FIG. 12). 701, the pressure sensor 530 is configured to The pressure sensor 53 operates to measure the force at the downstream portion of the tube during operation of the pump. 0 rises above a predetermined threshold during operation of the pump 501 to deliver fluid, and then If the pump detects pressure in the tubing that remains high after the pump has stopped, the pump 03 provides the first indication that an occlusion exists in the tube. , remains below a predetermined threshold or exceeds a predetermined threshold during operation of the pump 501 to deliver fluid. If it detects pressure rising above a certain value but dropping below a certain threshold when the pump is stopped At 705, the pump provides an indication that there is no blockage in the tubing. If it is determined in 3 that there is an obstruction in the tube, a verification subroutine V is started. During the validation routine, at 707, the ultrasonic sensor is configured to send an ultrasonic signal through a portion of the tube. A sensor reading above a predetermined threshold is detected by the ultrasonic sensor 564. If so, pump 501 determines at 709 that there is an occlusion in the tubing. The pump 501 then alerts or reads in memory that there is an occlusion in the tubing. If the signal reading from the ultrasonic sensor 564 is below a predetermined threshold, If so, the initial occlusion detection indication is not confirmed at 711. The pump 501 continues to Provide an alert that the routine could not be resumed or an indication of the blockage. It is possible.

[0056] In one aspect of the present disclosure, the alert may be visual, audible, or a combination thereof. A visual alert can be provided to the user via the display screen 9 (Figure 1) and / or LED 13. and an audio alert may be provided to the user via a speaker. Alerts can be provided to users to fix, resolve or adjust system issues. It can be done.

[0057] 13A-13C, the strain accommodated in the sensor track of FIGS. 6A and 6B can be seen. Sample results are shown in relation to an exemplary diagram of a soldered tube. A is the reading of the signal S of the sensor US by switching the emitter side and the detector side. It shows 10 separate tests that were run, each showing the return value. For example, run 1 first It provides an emitter that operates on the left side of the tube and a detector that operates on the right side of the tube, with a value of 358. Run 1 then switches the operation of sensor US, moving the emitter to the right side of the tube. Operate the detector on the left side of the tube and obtain a value of 494. The higher value of 494 is adopted by the system, which determines that fluid is flowing through the tube. Furthermore, as mentioned above, the emitter on the right side of the tube and the detector on the left side of the tube are A higher value of θ causes the tube to move to the right side of the tube track, as shown in Figure 5C. It is confirmed that the bias is present. Runs 2 to 10 are performed in the same manner. Runs 2, 3, 6 and For 8, the tube is biased to the right side of the tube track where the working emitter is located. For runs 4, 5, 7, 9 and 10, the tubes We can infer that the emitter is biased to the left side of the tube track. FIG. 3B graphically illustrates the results of FIG. 13A.

[0058] FIG. 13C shows that the value obtained by the signal S is also compared to a threshold value. According to one embodiment, the readings obtained by the sensor US are considered usable values. Before the experiment, at least a minimum threshold, say 74, must be met. For example, in both runs 3 If a value below 74 is obtained, the system immediately determines that a problem has occurred. Determine.

[0059] The threshold is set to take into account the materials of the tube and the sensor US, as well as the fluid passing through the tube. For this purpose, it can be set / determined during the manufacturing stage or during operation.

Relevant sample results are shown in the figures. Figures 14A-14F show accurate readings. The robustness of the system for obtaining the above-mentioned results and the robustness of the entire system are shown. According to Figs. 14A and 14B, the tube is properly placed in the tube track. Executions 1 to 5 are performed when the user is in the middle of the execution (mind). Furthermore, executions 1 to 5 are performed as described above in relation to Figure 8. As mentioned above, this is done according to the two sensor US positions A and B. In this example, Since the probe is centered within the tube track, it is possible to determine which side of the sensor US is the emitter or detector. It does not matter whether the device is configured to operate as a device. As shown in Fig. 1, the two US positions were obtained with the tube centered in the tube track. The maximum value that can be set is 805. Furthermore, according to another embodiment of the present disclosure, FIG. When the tube is biased toward the emitter in the tube track, runs 1 to 5 As noted above, runs 1-5 are performed using two U The tube is inserted into the tube according to positions A and B as shown in Figs. 14C and 14D. Maximum value obtained from two US positions when biased towards the emitter in the tube track is 1235. Further, according to another aspect of the present disclosure, looking at Figs. 14E and 14F Runs 1-5 are performed when the tube is biased towards the detector in the tube track. As mentioned above, runs 1-5 are performed using two sensor US positions as described above in connection with FIG. The procedure is carried out according to the procedures A and B. As shown in Figs. 14E and 14F, the tube is The maximum value obtained from the two sensor US positions when the probe is biased toward the detector in the probe track. The value is 891. These results show that when the tube is biased toward the US emitter, It is confirmed that a higher and more accurate reading is obtained by
