Description

Technical Field

[0001] This disclosure generally relates to monitoring characteristics associated with venous fluid flow, and particularly to a venous monitoring system having sensors and communication units. Background Technology

[0002] Infusion therapy is a common healthcare procedure that can be facilitated by vascular access devices. Patients in hospitals, home care, and other settings can receive fluids, medications, and blood products through vascular access devices. Additionally, blood can be drawn from a patient using vascular access devices. Blood draws are another common healthcare procedure that can be facilitated by vascular access devices.

[0003] Vascular access devices can be inserted into a patient's peripheral or central vascular system. Vascular access devices can be left in place for short periods (e.g., days), medium periods (e.g., weeks), or long periods (e.g., months to years). Vascular access devices can be used for continuous infusion therapy or intermittent infusion therapy. A common type of vascular access device is a catheter, such as, for example, a peripherally inserted venous catheter (PIVC) or a peripherally inserted central catheter (PICC).

[0004] A common type of catheter is the over-the-needle PIVC. An over-the-needle PIVC is attached to a guide needle with a sharp distal tip. The PIVC and guide needle can be assembled such that the distal tip of the guide needle extends beyond the distal tip of the PIVC, with the bevel of the needle facing away from the patient's skin. The PIVC and guide needle are typically inserted into the patient's blood vessels, such as arteries, veins, or any other vascular system, through the skin at a shallow angle.

[0005] To verify proper placement of the PIVC within the blood vessel, clinicians typically observe for blood "flashback" within the PIVC. Flashback occurs when blood travels proximally between the outer surface of the guide needle and the inner surface of the PIVC, reaching the flashback window or flashback chamber. This allows the clinician to visualize the blood and confirm the guide needle's placement within the vascular system. Once placement is confirmed, the clinician can temporarily block venous flow and remove the guide needle, leaving the PIVC in place for future blood draws and / or fluid infusions.

[0006] Once a PIVC is placed inside a blood vessel and medication is delivered via the PIVC, extravasation can occur, with the drug leaking into the soft tissue adjacent to the vessel. A sensor can be attached to the patient's skin near the catheter insertion site to monitor for extravasation events. However, this detection method may only be effective after a significant amount of medication has leaked from the catheter / vessel and migrated to the patient's skin. Furthermore, the sensor placed on the patient's skin is an additional accessory and incurs costs; it must be periodically removed and reattached, such as when the patient goes to the bathroom or takes a shower.

[0007] Procedures used to verify proper placement of the PIVC, fluid access occlusion or patency, and catheter extravasation or permeation typically require visual observation, consideration, and judgment by a clinician. In some cases, clinicians can determine the degree of catheter occlusion by manually applying pressure to the catheter with a syringe or by observing the difficulty of drawing blood from the catheter. When a problem or difficulty is identified with the catheter or other devices coupled to it, such as fluid access occlusion, extravasation, or permeation, the catheter may be removed, replaced, or an enzyme may be introduced to restore fluid flow through the catheter. In some cases, using conventional procedures (such as visual observation or manual examination of IV tubing and catheters) may not accurately or promptly identify catheter-related problems or difficulties. Summary of the Invention

[0008] The disclosed subject matter relates to a venous monitoring system that can be coupled to an IV kit or catheter to detect characteristics associated with any IV kit or catheter, including PIVC placement, fluid access occlusion or patency, extravasation, and permeation. The venous monitoring system of this disclosure provides an assessment of the IV kit or catheter to determine whether a problem or malfunction may have occurred or has occurred. In this way, the venous monitoring system allows for the timely identification of symptoms and potential or existing problems. Timely identification of symptoms and problems can allow clinicians, caregivers, or other participants to correct the condition leading to the problem, reposition the IV kit or catheter, or otherwise replace the IV kit or catheter.

[0009] In some embodiments, a vein monitoring system is disclosed, comprising: a housing having an inner surface forming a fluid passage extending through the housing and configured to couple with a catheter; a sensor coupled to the fluid passage to detect data of fluid in the fluid passage; a communication unit coupled to the sensor to communicate data sensed by the sensor; and a power supply electrically coupled to the sensor.

[0010] In some embodiments, a vein monitoring system is disclosed and includes: a housing having a first end, a second end opposite to the first end, a longitudinal axis formed between the first and second ends, and an inner surface forming a fluid passage extending through the housing and configured to be coupled to a catheter; a sensor coupled to the fluid passage to detect data of fluid in the fluid passage; a communication unit coupled to the sensor to communicate data sensed by the sensor; and a power supply electrically coupled to the sensor.

[0011] In some cases, this disclosure provides a vein monitoring system comprising: a catheter having a catheter hub and a catheter needle, the catheter hub including a housing having an inner surface forming a fluid passage extending through the housing, and the catheter needle having a proximal end, a distal end, and an inner surface forming a lumen extending through the catheter needle and fluidly coupled to the fluid passage; a sensor coupled to the housing to detect data of fluid in either the fluid passage or the lumen; a communication unit coupled to the housing for transmitting data sensed by the sensor; and a power supply coupled to the housing and electrically coupled to the sensor.

[0012] In some cases, methods for providing a venous monitoring system are disclosed as providing a housing including a first end, a second end opposite the first end, and an inner surface forming a fluid passage extending through the housing and configured to be fluidly coupled to a catheter; providing a sensor coupled to the fluid passage to detect data of fluid in the fluid passage; providing a communication unit coupled to the sensor to communicate data sensed by the sensor; and providing a power source electrically coupled to the sensor.

[0013] Therefore, this application addresses several operational challenges in evaluating IV kits, IV tubes, or catheters, including proper placement, fluid access blockage or patency, and extravasation or permeation, and provides numerous improvements that enable clinicians and patients to enhance accuracy, timeliness, safety, and efficacy.

[0026] The disclosed venous monitoring system includes various features to facilitate the detection and assessment of multiple aspects of venous access characteristics, including the correct position of the catheter within the vein, occlusion or patency of the fluid pathway, and extravasation or permeation of the catheter.

[0027] In the following detailed description, numerous specific details are set forth to provide a comprehensive understanding of the subject matter. It should be understood that the subject matter can be practiced without some of these specific details. In other instances, well-known structures and techniques have not been shown in detail so as not to obscure the subject matter. Furthermore, while this description sets forth specific details of various embodiments, it should be understood that this description is merely illustrative and should not be construed as limiting in any way.

[0028] Now refer to the attached diagram, Figure 1 An example of a vein monitoring system 100 coupled to a patient 10 according to some embodiments is shown. The vein monitoring system 100 is coupled to a catheter 12 and a tube 14, wherein the tube is coupled to the vein monitoring system 100 such that fluid (e.g., blood) moving through the tube 14 will move through the fluid pathway of the vein monitoring system 100.

[0029] The vein monitoring system 100 can be coupled to the tube 14 by inserting a tube into the vein monitoring system 100, such that the vein monitoring system 100 is positioned between a first end 16 and a second end 18 of the tube. In some embodiments, the vein monitoring system 100 can be coupled between individual segments of the tube. For example, a first end of a first segment can be coupled to the vein monitoring system 100, and a second end of a first segment can be coupled to the catheter 12, and a first end of a second segment can be coupled to another portion of the vein monitoring system 100, and a second end of a second segment can be coupled to another device, such as a Luer lock adapter. When coupled to the vein monitoring system 100, the first end of the first segment and the first end of the second segment are in fluid communication with the fluid passage of the vein monitoring system 100.

[0030] When ready to insert a catheter into a patient, the venous monitoring system 100 can be detachably coupled to the tube 14, thereby minimizing any disruption to the current workflow practices of caregivers. This disclosure also envisions that the venous monitoring system 100 can be coupled to either the catheter 12 or the tube 14 in a manner that resists removal of the venous monitoring system 100 via any suitable coupling mechanism, including, for example, threads, snap-fit, interference fit, friction, or adhesive.

[0031] The venous monitoring system 100 can be configured as an anchor or catheter fixation device. To facilitate anchoring or securing the catheter to the patient and to resist accidental separation of the catheter from the patient, the venous monitoring system 100 can be configured to be coupled to the patient by adhesiveting the venous monitoring system 100 to the patient or by applying an adhesive between the venous monitoring system 100 and the patient. If a portion of the tube 14 (such as the first end 16 of the tube) is pulled in a direction away from the catheter 12, the venous monitoring system 100, configured as a catheter fixation device to the patient, can resist separation of the catheter from the patient by resisting the force transmitted to the catheter due to the pulling of the tube.

[0032] Figure 2An exemplary embodiment of a vein monitoring system 200 fluidly coupled to a catheter 12 inserted into a patient 10 is shown. The vein monitoring system 200 includes features similar to those described and / or shown in other parts of this disclosure for the vein monitoring system 100. Therefore, certain features of the vein monitoring system 200 are indicated by reference numerals similar to those used with respect to the vein monitoring system 100.

[0033] The vein monitoring system 200 is fluidly coupled to the catheter 12 such that fluid (e.g., blood) moving through the tube 14 will move through the fluid pathway of the vein monitoring system 200. To fluidly couple the vein monitoring system 200 to the catheter 12, a first end 16 of the tube is coupled to a first portion of the vein monitoring system 200 and is in fluid communication with the fluid pathway of the vein monitoring system, and a second end 18 of the tube is coupled to the catheter 12. The second portion of the vein monitoring system 200 may be configured to be coupled to another segment of the tube or another device, such as a needleless connector, a Luer lock adapter, a syringe, or a blood collection device.

[0034] Figure 3 An exemplary embodiment of a vein monitoring system 300 is shown, configured to have a catheter hub for insertion into a patient 10. The vein monitoring system 300 includes features similar to those described and / or shown in other parts of this disclosure for vein monitoring systems 100, 200. Therefore, certain features of the vein monitoring system 300 are indicated by similar reference numerals as used with respect to vein monitoring systems 100, 200.

[0035] The vein monitoring system 300 includes a first end or proximal end and a second end or distal end. The first end of the vein monitoring system 300 is coupled to a second end 18 of a tube, and the second end of the vein monitoring system is coupled to or includes a catheter needle. Each of the tube 14 and the catheter needle is in fluid communication with the fluid pathway of the vein monitoring system.

[0036] In any embodiment of this disclosure, including vein monitoring systems 100, 200, and 300, the vein monitoring system may include a housing that can be coupled to any of an IV tube and / or catheter. The housing includes an inner surface that forms a fluid passage extending through the housing to allow fluid movement through it. To sense, collect, and identify data associated with the fluid moving through the housing, the vein monitoring system includes one or more sensors and a communication unit. The sensors are coupled to the fluid passage and can be in indirect or direct contact with the fluid in the fluid passage. The sensors may be coupled to the housing, or the sensors may be positioned within a cavity formed by the housing. Furthermore, the vein monitoring system may include more than one sensor and more than one communication unit.

[0037] The sensor can detect the condition and characteristics of the fluid in the fluid passage, such as pressure changes caused by the fluid. When the venous monitoring system is in fluid communication with the fluid passage extending through the catheter, the sensor can detect intravascular pressure changes, such as peripheral venous pressure (PVP) waveforms. Therefore, by detecting the condition within the fluid passage, the sensor can detect the condition within the fluid passage extending through catheter 12. In some embodiments of this disclosure, the sensor of the venous monitoring system can detect the presence or absence of a PVP waveform.

[0038] One or more sensors in a vein monitoring system may include any one of a pressure sensor, a temperature sensor, and / or a flow sensor. In some embodiments, a pressure sensor may be configured to detect the fluid pressure within the fluid passage. In some embodiments, a flow sensor may be configured to detect the fluid velocity and / or fluid flow rate within the fluid passage.

[0039] The pressure sensor may include any suitable pressure sensor capable of detecting fluid pressure within a fluid passage. In some embodiments, the pressure sensor may include a pressure-sensitive device, which may be any of capacitive, resistive, optical, and / or ultrasonic. In some embodiments, a first surface of the pressure sensor may be exposed to fluid within the fluid passage, and a second surface of the pressure sensor may be exposed to a liquid or gas at a reference pressure, thereby providing a reference surface. In some embodiments, a measured pressure difference between the first and second surfaces of the pressure sensor may provide an indication of the fluid pressure exposed at the first surface.

[0040] In cases where a vein monitoring system includes a flow sensor, the flow sensor may include any suitable flow sensor capable of detecting the flow rate of fluid through the fluid passage. While various suitable fluid flow sensors are well known and can be used, illustrative examples of suitable fluid flow sensors may include, but are not limited to, optical sensors, piezoelectric sensors, acoustic sensors, reed switch-based sensors, magnetic sensors, ultrasonic sensors, orifice flow meters, venturi flow meters, etc.

[0041] The vein monitoring system may also include a communication unit that generates an output signal based on data sensed or collected by sensors. The output signal may include one or more different formats, including but not limited to visual signals, auditory signals, tactile signals, and / or wirelessly transmitted output signals. For example, a visual signal may be a light source visible to a person near the vein monitoring system. An auditory signal may be a speaker or piezoelectric alarm that can be heard by a person near the vein monitoring system. A tactile signal may be a vibrating motor or tactile actuator that can be felt by a person in contact with the vein monitoring system. In some embodiments, for each condition or problem, the vein monitoring system may alert the patient, caregiver, other person, or receiving location of the catheter problem or condition by conveying any of a different light color or pattern, a different sound color or pattern, or a different tactile or vibration pattern. Furthermore, this disclosure contemplates that any embodiment of the vein monitoring system may include wirelessly transmitting the output signal of the vein monitoring system 100, 200, 300 to receiving location 20.

[0042] The vein monitoring system disclosed herein may also include a reset command, switch, or button, which can be activated by any of the patient, caregivers, or other personnel, or from another system associated with the vein monitoring system. In some embodiments of this disclosure, a reset may be used to change the characteristics of the output signal, such as, for example, muting, turning off, silencing, or resetting the output signal. In some embodiments, a reset may also include other functions, such as turning the vein monitoring system off or on, or resetting / restarting the vein monitoring system.

[0043] In some embodiments, circuitry such as a printed circuit board (“PCB”) and / or a power source is housed within the housing. The power source may include a battery, which may be rechargeable and / or replaceable. In some embodiments, the location of the circuitry and / or power source within the housing may vary. The power source may be electrically coupled to a sensor and may be configured to power one or more sensors. In some embodiments, the power source may be located remotely from the circuitry. In some embodiments, non-volatile memory storage locations, such as flash memory, may be included on the circuitry to allow data sensed by the sensors to be temporarily or permanently stored thereon. In some embodiments, the storage location may be accessible to a user and / or may be transferred to a receiving location.

[0044] In some embodiments, either the communication unit or the processor may be disposed on a circuit that may be electrically coupled to one or more sensors. In some embodiments, the presence of a blockage in the conduit 12 may be determined based on data sensed by one or more sensors. In some embodiments, the blockage may partially block fluid flow through the conduit 12, or may completely or substantially completely block fluid flow through the conduit 12. In some embodiments, in response to determining the presence of a blockage based on data sensed by the sensors, the communication unit may transmit an output signal. The output signal may be transmitted in one or more formats, including as a wireless signal to a receiving location, a visual signal (e.g., an LED light), an audio signal (e.g., an alarm sound), and a tactile signal (e.g., a vibration mechanism).

[0045] In some embodiments, an alarm may be provided at the receiving location 20 in response to receiving an output signal from the receiving location 20. In some embodiments, an alarm from either the vein monitoring system or the receiving location may include visual, auditory, and / or tactile signals, such as, for example, a change in the state of a light or a buzzing sound. In some embodiments, an indicator at the receiving location may be configured to provide an alarm.

[0046] Figure 4 A perspective view showing an embodiment of a vein monitoring system 100 configured as a catheter fixation device, and... Figure 5 A cross-sectional side view of a venous monitoring system 100 along line 5-5 is shown. The venous monitoring system 100 includes a housing 120 having a fluid passage that can be coupled to an IV catheter, and the venous monitoring system 100 can be coupled to a patient to resist catheter dissociation from the patient in the event of pulling of the IV catheter in a direction away from the catheter. The housing 120 includes a first end 122 and a second end 124, wherein the second end 124 is opposite to the first end 122 of the housing. The housing 120 also includes an inner surface forming a fluid passage 126 extending through the housing 120 and extending from the first end 122 to the second end 124. The fluid passage 126 allows fluid, such as blood, to move through it. When fluid is in the fluid passage 126, sensors of the venous monitoring system 100 can sense and collect data associated with the fluid.

[0047] To sense and collect data associated with the fluid in the fluid passage 126, the venous monitoring system 100 includes a sensor 130 and a communication unit 140. The sensor 130 is coupled to the fluid passage 126 and can be in indirect or direct contact with the fluid in the fluid passage 126. The sensor 130 can detect the condition and characteristics of the fluid in the fluid passage 126, such as changes in pressure and / or temperature caused by the fluid. When the fluid passage 126 is in fluid communication with a catheter, the sensor 130 can detect changes in intravascular pressure, such as peripheral venous pressure (PVP) waveforms.

[0048] The sensor 130 of the vein monitoring system 100 includes a pressure sensor that can detect the pressure of the fluid within the fluid passage 126. The sensor 130 can detect the condition and characteristics of the fluid in the fluid passage 126 by inserting a tube 14 through the fluid passage 126 and through the housing 120, or by coupling one end of the tube to the housing 120, allowing fluid to move from the tube into and through the fluid passage 126 of the housing 120.

[0049] The vein monitoring system 100 also includes a communication unit 140, which generates an output signal based on data sensed by the sensor 130. The output signal may include one or more formats, including but not limited to visual signals, auditory signals, tactile signals, and / or wirelessly transmitted output signals. In embodiments of the vein monitoring system 100, the visual signal is a light source 142, which may be visible to a person or device near the vein monitoring system. In some embodiments, for each condition or problem detected by the system, the vein monitoring system may issue an alarm to notify the patient, caregiver, other personnel, or the receiving location of the catheter problem or condition by conveying different light colors or patterns, different sounds or patterns, or different tactile or vibration patterns. Furthermore, the communication unit may wirelessly transmit the output signal from the vein monitoring system 100 to the receiving location 20 or another device.

[0050] The vein monitoring system 100 also includes a reset button 146, which can be activated by any of the patient, caregivers, or other personnel, or from another system associated with the vein monitoring system. The reset button 146 can be used to change the characteristics of the output signal, such as, for example, muting, turning off, silencing, or resetting the output signal. In some embodiments, the reset button 146 may also include other functions, such as turning the vein monitoring system 100 off or on, or resetting / restarting the vein monitoring system 100.

[0051] Within the housing 120, the vein monitoring system 100 includes circuitry 150 and a power supply 152, which, for example... Figure 5As shown. In some embodiments, circuit 150 may include a non-volatile memory storage location, such as flash memory, to enable data sensed by the sensor to be stored thereon, either temporarily or permanently. In some embodiments, the storage location may be accessible to a user and / or may be transferred to a receiving location.

[0052] Sensor 130, communication unit 140, light source 142, and power supply 152 are coupled to circuit 150. Power supply 152 is electrically coupled to sensor 130 and provides power to one or more sensors. Power supply 152 may include a battery, which may be rechargeable and / or replaceable. In some embodiments, power supply 152 may be located remotely from circuit 150.

[0053] Either the communication unit 140 and the processor may be disposed on circuitry 150, which may be electrically coupled to sensor 130. In some embodiments, the presence of a blockage in conduit 12 may be determined based on data sensed by sensor 130. A blockage may partially or completely block fluid flow through conduit 12. In some embodiments, in response to determining the presence of a blockage based on data sensed by sensor 130, communication unit 140 may wirelessly transmit an output signal to a receiving location.

[0054] To detect characteristics associated with fluid passage 126 and assess whether there is blockage or patency of the fluid passage, or extravasation or permeation of the conduit, the circuit may include an application-specific integrated circuit configured to analyze data from sensor 130 and any additional sensors or data sources.

[0055] Referring to the housing 120 of the vein monitoring system 100, the longitudinal axis A1 of the housing is defined by a fluid passage 126 extending through the housing 120. The fluid passage 126 extends from a first end 122 of the housing to a second end 124 and extends along the longitudinal axis A1. The length L1 of the housing is defined between the first end 122 and the second end 124. In some embodiments, the fluid passage 126 and the longitudinal axis A1 are coaxial.

[0056] The inner surface of the housing forming the fluid passage 126 is shaped as a closed channel through the housing 120, wherein the closed channel has a first opening 121 at a first end 122 of the housing and a second opening 123 at a second end 124 of the housing. In some embodiments, the inner surface of the housing forming the fluid passage also includes one or more openings into the fluid passage 126. The one or more openings can allow the sensor to extend into the fluid passage 126 to expose the sensor to the fluid in the fluid passage while maintaining the closed structure of the fluid passage.

[0057] The housing 120 also defines a top surface 162, a bottom surface 164, and a height H1 between the top and bottom surfaces. The housing 120 extends laterally outward in a direction away from the longitudinal axis A1 to form a first wing 166 and a second wing 168. The first wing 166 and the second wing 168 form opposite lateral ends of the housing 120, thereby defining a width W1 of the housing between them.

[0058] To facilitate attachment of the vein monitoring system 100 to a patient, the height H1 of the housing may decrease along at least a portion of the housing width W1. In some embodiments, the height H1 decreases along the width W1 in a direction from the longitudinal axis A1 toward the lateral ends of the housing 120. In some embodiments of this disclosure, the height H1 decreases in a direction from the longitudinal axis A1 toward each lateral end of the housing 120. The housing 120 is also shaped such that the width W1 of the housing is greater than the length L1 of the housing. Furthermore, the height H1 of the housing is less than both the width W1 and the length L1 of the housing.

[0059] To facilitate anchoring or securing the vein monitoring system 100 to a patient, tape may be placed on at least a portion of the housing 120 and extended onto the patient, such that the housing 120 is positioned between the tape and the patient. For example, a medical tape may be placed on the top surface 162 of one or more wings and extended onto the patient. In some embodiments of this disclosure, tape or adhesive may be applied along the bottom surface 164 of the housing, allowing the housing to adhere to the patient.

[0060] A tube 14 extending from a catheter or IV kit can be coupled to the vein monitoring system 100 by coupling one end of a first tubing segment to the fluid passage 126 at the first end 122 of the housing. One end of a second tubing segment can be coupled to the fluid passage 126 at the second end 124 of the housing. Thus, fluid moving through either the first or second tubing segment will move through the fluid passage 126 of the housing. In some embodiments of this disclosure, the tube 14 can be inserted through the housing 120, for example, through the first end 122 and the second end 124, such that the vein monitoring system 100 is positioned between the first end 16 and the second end 16 of the tube.

[0061] In some embodiments of this disclosure, the vein monitoring system 200 is configured as a fluid coupler that can be coupled to a tube 14 extending from the catheter 12. Figure 6 The perspective view shows an example of the vein monitoring system 200, and Figure 7A cross-sectional side view of the vein monitoring system 200 along line 6-6 is shown. The vein monitoring system 200 includes features similar to exemplary embodiments of the vein monitoring systems 100, 300 described in this disclosure. Therefore, certain features of the vein monitoring system 200 are indicated by similar reference numerals as those used with respect to other vein monitoring systems 100, 300 relating to this disclosure.

[0062] The vein monitoring system 200 includes a housing 220 having a first end 222 and a second end 224, wherein the second end 226 is opposite to the first end 222 of the housing. The housing 220 also includes an inner surface forming a fluid passage 226 extending through the housing 220 and from the first end 222 to the second end 224. The fluid passage 226 allows fluid, such as blood, to move through it. As fluid moves through the fluid passage 226, sensors of the vein monitoring system 200 can sense and identify data associated with the fluid.

[0063] To sense and identify data associated with the fluid moving through the fluid passage 226, the venous monitoring system 200 includes a sensor 130 and a communication unit 140. The sensor 130 is coupled to the fluid passage 226 and can be in indirect or direct contact with the fluid in the fluid passage 226. The sensor 130 can detect the condition and characteristics of the fluid in the fluid passage 226, such as pressure changes caused by the fluid. When the fluid passage 226 is in fluid communication with a catheter, the sensor 130 can detect intravascular pressure changes, such as peripheral venous pressure (PVP) waveforms.

[0064] The vein monitoring system 200 also includes a communication unit 140, which generates an output signal based on data sensed by the sensor 130. The output signal may include one or more different formats, including but not limited to visual signals, auditory signals, tactile signals, and / or wirelessly transmitted output signals. In embodiments of the vein monitoring system 200, the visual signal is a light source 142, which may be visible to a person near the vein monitoring system. Furthermore, the communication unit can wirelessly transmit the output signal from the vein monitoring system 200 to a receiving location 20.

[0065] The vein monitoring system 200 includes a reset button 146, which can be activated by any of the patient, caregivers, or other personnel, or from another system associated with the vein monitoring system. The reset button 146 can be used to change characteristics of the output signal, such as, for example, mute, turn off, sleep, or reset the output signal. In some embodiments, the reset button 146 may also include other functions, such as turning the vein monitoring system 200 off or on, or resetting / restarting the vein monitoring system 200.

[0066] Within housing 220, the vein monitoring system 200 includes circuitry 150 and a power supply 152. Sensor 130, communication unit 140, light source 142, and power supply 152 are coupled to circuitry 150. Power supply 152 is electrically coupled to sensor 130 and provides power to one or more sensors. Power supply 152 may include a battery, which may be rechargeable and / or replaceable. In some embodiments, power supply 152 may be located remotely from circuitry 150.

[0067] The housing 220 of the vein monitoring system has a longitudinal length L2 extending between a first end 222 and a second end 224 of the housing. A fluid passage 226 extends along the longitudinal length L2 of the housing 220 and passes through the housing 220 to define a longitudinal axis A2 of the housing. When viewed in a cross-sectional plane transverse to the longitudinal axis A2, the housing forms a cylindrical or tubular shape, with its inner surface defining the fluid passage 226.

[0068] The inner surface of the housing forming the fluid passage 226 is shaped as a closed channel through the housing 220, wherein the closed channel has a first opening at a first end 222 of the housing and a second opening at a second end 224 of the housing. In some embodiments, the inner surface of the housing forming the fluid passage also includes one or more openings into the fluid passage 226. The one or more openings allow the sensor 130 to extend into the fluid passage 226 and maintain the closure of the fluid passage.

[0069] The housing 120 also has an outer surface 262 with one or more openings to allow user access to features such as output signals (e.g., light source 142, reset button 146, and power supply 152). The outer surface 262 of the housing defines a width transverse to the longitudinal axis A2 and can vary along the length L2 of the housing. In some embodiments, the outer surface 262 of the housing is shaped as a barb, the width of which decreases in a direction toward either the first end 222 or the second end 224 of the housing.

[0070] refer to Figure 7 A cross-sectional view of the vein monitoring system 200 shows, for example, a portion of the housing along a longitudinal length L2 between the first end 222 and the second end 224 of the housing having a first width W21. Near the first end 222 and the second end 224 of the housing, the housing has a second width W22 greater than or equal to the first width W21. Furthermore, the width of the outer surface 262 of the housing decreases along another portion of the longitudinal length L2 extending to the first end 222 and the second end 224 of the housing to a width W3 at the first end 222 and the second end 224 of the housing. Therefore, the outer surface 262 of the housing can be formed in a barb shape from the second width W22 to either the first end 222 or the second end 224 of the housing.

[0071] The barbed housing allows the venous monitoring system 200 to be coupled to the tube 14 of the catheter or IV kit. The venous monitoring system 200 can be coupled to the tube 14 by inserting either the first end 222 or the second end 224 of the housing into the lumen of the first end 16 or the second end 18 of the tube. Figure 2 The housing 220 can be inserted into the tube 14 until the barbed portion of the outer surface 262 is within the lumen of the tube 14. In some embodiments of this disclosure, the other of the first end 222 or the second end 224 of the housing can be inserted into the lumen at one end of another tube, allowing fluid (e.g., blood) to move through the tube 14, through the fluid passage 226, and then to the other tube. In some embodiments of this disclosure, the other of the first end 222 or the second end 224 of the housing can have the shape of a connector configured to couple to another device. For example, the first end 222 or the second end 224 of the housing can have the shape of any of a Luer lock adapter, a threaded adapter, a tubular sliding joint, or a pinless connector.

[0072] Examples of vein monitoring systems 200 include Figure 8 As shown, the PIVC catheter is coupled to the patient. The venous monitoring system 200 is coupled to the tube 14 of the catheter or IV kit. To fluidly couple the venous monitoring system 200 to the catheter 12, a first end 16 of the tube is coupled to a first portion of the venous monitoring system 200 and is in fluid communication with the fluid pathway of the venous monitoring system, and a second end 18 of the tube is coupled to the catheter 12. The venous monitoring system 200 communicates with a clinician monitoring device serving as a receiving location 20. As described in this disclosure, the communication unit 140 of the venous monitoring system can send data to and receive data from the receiving location 20.

[0073] In some embodiments of this disclosure, the vein monitoring system 300 is configured to include a catheter hub for a catheter needle. Figure 9 An example of a vein monitoring system 300 is shown in the perspective view. The vein monitoring system 300 includes features similar to those of the example embodiments of the vein monitoring systems 100, 200 described in this disclosure. Therefore, certain features of the vein monitoring system 300 are indicated by reference numerals similar to those used with respect to other vein monitoring systems 100, 200.

[0074] The vein monitoring system 300 includes a housing 320 having a first end 322 and a second end 324, wherein the second end 322 is opposite to the first end 322 of the housing. The housing 320 also includes an inner surface forming a fluid passage 326. Figure 9The fluid passage 326, indicated by a dashed line, extends through the housing 320 and from the first end 322 of the housing to the second end 324. The fluid passage 326 allows fluids, such as blood, to move through it. As fluid moves through the fluid passage 326, sensors in the vein monitoring system 300 can sense and identify data associated with the fluid.

[0075] The housing 320 also defines a top surface 361, a bottom surface, and the height between the top and bottom surfaces. The longitudinal length L3 of the housing 320 is defined between the first end 322 and the second end 324 of the housing. A fluid passage 326 extends along the longitudinal length L3 of the housing 320 and passes through the housing 320, thereby also defining the longitudinal axis A3 of the housing.

[0076] The housing 320 extends laterally outward in a direction away from the longitudinal axis A3 to form a first wing 366 and a second wing 368. The first wing 366 and the second wing 368 form opposing lateral sides of the housing 320, thereby defining at least a portion of the width of the housing between them. In some embodiments of this disclosure, the outer surface of the bottom surface of the housing 320, including the first wing 366 and the second wing 368, may form a surface configured to engage with a patient. The outer surface of the bottom surface of the housing 320 may be formed with any of a planar, concave, or convex surface.

[0077] The width of the housing is transverse to the longitudinal axis A3, and the width of the housing can vary along the length L3 of the housing. In some embodiments, the outer surface 362 of the housing has a first width W31 at the first end 322 of the housing, and a second width W32 near the proximal ends of the first wing 366 and the second wing 368, i.e., near the first end 322 of the housing. The width of the housing decreases along the length of the first wing 366 and the second wing 368 in the direction toward the second end 324 of the housing. Therefore, in some embodiments of this disclosure, the second width W32 is greater than the first width W31. Furthermore, this disclosure contemplates embodiments in which the second end 324 of the housing includes a width equal to or less than the first width W31, or in some embodiments, the second end 324 of the housing includes a width W33 less than the first width W31 and the second width W32.

[0078] In some embodiments of this disclosure, the catheter needle 380 is coupled to a second end 324 of the vein monitoring system 300. The catheter needle 380 has a proximal end 382 coupled to the housing 320, a distal end 384 opposite to the proximal end 382, ​​and an inner surface forming a lumen 386. The lumen 386 extends through the catheter needle 380 and is fluidly coupled to the fluid passage 326 (i.e., the catheter hub) of the housing 320. Therefore, the sensor 130 can detect the condition and characteristics of the fluid moving from the lumen 386 of the catheter needle to the fluid passage 326 of the housing.

[0079] Although the catheter needle 380 is coupled to the housing 320, this disclosure contemplates embodiments in which the catheter needle 380 is detachably coupled to the housing 320 and resists removal of the catheter needle 380 from the housing 320. In some embodiments, the housing 320 and the catheter needle 380 may be coupled together via any suitable coupling mechanism, including, for example, threads, snap-fit, interference fit, friction, or adhesive.

[0080] To sense and identify data associated with fluid within or moving through the fluid passage 326, the venous monitoring system 300 includes a sensor 130 and a communication unit. The sensor 130 is coupled to the fluid passage 326 and can be in direct or indirect contact with the fluid in the fluid passage 326. The sensor 130 can detect the condition and characteristics of the fluid in the fluid passage 326, such as pressure changes caused by the fluid. When the catheter needle 380 is venously positioned in a patient, the sensor 130 can detect intravascular pressure changes, such as peripheral venous pressure (PVP) waveforms.

[0081] The vein monitoring system 300 also includes a communication unit that generates an output signal based on data sensed by the sensor 130. The output signal may include one or more different formats, including but not limited to visual signals, auditory signals, tactile signals, and / or wirelessly transmitted output signals. In an embodiment of the vein monitoring system 300, the output signal is a piezoelectric alarm 342, which can be heard by a person near the vein monitoring system. Furthermore, the communication unit can wirelessly transmit the output signal from the vein monitoring system 200 to the receiving location 20.

[0082] The vein monitoring system 300 includes a reset button 146, which can be activated by any of the patient, caregivers, or other personnel, or from another system associated with the vein monitoring system. The reset button 146 can be used to change characteristics of the output signal, such as, for example, mute, turn off, sleep, or reset the output signal. In some embodiments, the reset button 146 may also include other functions, such as turning the vein monitoring system 300 off or on, or resetting / restarting the vein monitoring system 300.

[0083] Within housing 320, the vein monitoring system 300 includes circuitry and a power supply 152. Sensor 130, a communication unit, a piezoelectric alarm 342, and power supply 152 are coupled to circuitry 150. Power supply 152 is electrically coupled to sensor 130 and provides power to one or more sensors. Power supply 152 may include a battery, which may be rechargeable and / or replaceable. In some embodiments, power supply 152 may be located remotely from circuitry 150.

[0084] The inner surface of the housing forming the fluid passage 326 is shaped as a closed channel through the housing 320, wherein the closed channel has a first opening at a first end 322 of the housing and a second opening at a second end 324 of the housing. In some embodiments, the inner surface of the housing forming the fluid passage 326 further includes one or more openings into the fluid passage 326. The one or more openings allow the sensor 130 to extend into the fluid passage 326 and maintain the closure of the fluid passage.

[0085] The housing 320 also has an outer surface 362 with one or more openings to allow user access to features such as output signals (e.g., alarm 342, reset button 146, and power supply 352). Features of the vein monitoring system 300 (which may include, but are not limited to, alarm 342, reset button 146, and power supply 352) can be located on any part of the housing, including the first wing 366 and the second wing 368. Figure 9 In the example of the vein monitoring system 300, a reset button 146 and a power supply 352 are located on the first wing 366 and the second wing 368, respectively. A sensor 130 and a piezoelectric alarm 342 are located in the portion of the housing located between the first wing 366 and the second wing 368.

Examples of clinician monitoring devices may include computing devices, mobile phones, smartphones, tablets, laptops, desktop computers, medical devices, or connected devices (e.g., smartwatches, smart glasses, or any other connected device). In some embodiments, the clinician monitoring device may provide alarms in addition to or as an alternative to a monitoring device that provides alarms. In some embodiments, the clinician monitoring device may include a pump that may be coupled to a vein monitoring system or to tubing 14 coupled to a vein monitoring system. The pump may be configured to infuse into the vein monitoring system in response to receiving an output signal.

[0087] In some embodiments, the clinician monitoring device may include a display screen 22 that can provide alerts. In some embodiments, the alert may include phrases such as, for example, “partial congestion” or “complete congestion”. In some embodiments, the alert may include visual cues on the display screen 22, such as a portion 24 of the display screen that lights up or changes color. In some embodiments, the portion 24 of the display screen may flash or change the flashing rate to provide an alert. In some embodiments, electronic health records may be displayed on the display screen of the clinician monitoring device.
