Abstract

This disclosure generally describes hybrid connectors for medical devices. Such connectors can provide multiple connection types to facilitate communication of a distal medical instrument to and from a monitoring system or power source where multiple communication types are required. Such communication can be electrical, electronic, fluid, optical, and / or any other energy or material used by the medical instrument. Connectors for hemodynamic monitoring devices can use connectors that include fluid communication and electrical connections to connect to blood pressure cuffs and other hemodynamic sensors.

Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 63 / 489,838, entitled "Multi-Connector with Two-Step Alignment for Hybrid Applications," filed March 13, 2023, the entire disclosure of which is incorporated herein by reference for all purposes.

[0002] The present disclosure relates to systems and devices having multiple connectors for medical devices and monitoring systems. [Background technology]

[0003] Sensors and other peripheral devices may require multiple types of connectors. For example, in the medical field, hemodynamic monitoring systems may utilize pneumatic and electrical communication to monitor vital signs such as blood pressure, blood oxygen levels, and other hemodynamic parameters. Fluid and electrical connectors have different requirements for ensuring proper communication / connection; therefore, when a device requires both, two or more separate connectors are used. While some systems may use a single connector that provides both fluid communication and electrical connection, such systems typically involve a trade-off between communication / connection types. For example, tight tolerances for air communication may result in loose connections between electronic devices, and vice versa. This trade-off can compromise either fluid communication or electrical connection, resulting in a less-than-optimal sensor.

[0004] Furthermore, conventional connectors tend to have larger profiles, which can pose a risk of misalignment, potentially compromising communication / connection. Therefore, there is a need to develop connectors that prevent misalignment and provide easier or more reliable communication / connection. Furthermore, connectors that allow blind connection can be beneficial when the connection operation is obscured by a blanket or other cover. Summary of the Invention [Means for solving the problem]

[0136] Referring now to these figures, the systems and devices of the present disclosure generally relate to a multi-function connector for use in a medical device ( FIG. 1A ). The multi-function connector 101 is capable of coupling a medical monitor, power source, or other type of supply 103 to a medical instrument 105. Many medical instruments may require the use of energy or matter, such as (for example) electrical signals, power, electron flow, fluid, or light, to perform a task; these energies or substances are often provided by an external source (i.e., the medical instrument is remote from the source). Furthermore, many medical instruments require the transmission of signals, diagnostic, functional, or other information to a medical monitor in order to obtain the signal or information distally from the medical monitor. In many cases, the energy or substance source is housed with the monitor in a single device, such as a hemodynamic monitor that provides the energy and pressurized fluid needed to perform blood pressure monitoring via a distally located blood pressure cuff and sensor, and can also receive and display diagnostic information from the cuff and sensor on the monitor's display.

[0137] When a distally located instrument requires more than one type of energy or substance, typically two or more separate connectors are used, or a single multi-function connector is used. As previously mentioned, many multi-function connectors have tolerance trade-offs between the multiple types of connections, resulting in less than desirable quality. This is particularly true when the multi-function connector must use two or more functionally distinct connector types, such as when connecting a power source and a fluid supply. Such trade-offs can arise due to the difficulty of manufacturing and / or fabricating a multi-function connector having two or more types of connectors within a single, compact housing. As described herein, several systems and devices provide multi-function connections within a single, compact housing for connecting multiple types of sources to a distal medical instrument. In certain implementations, the multi-function connector provides electrical connection and fluid communication. The fluid can be gaseous or liquid and can be pressurized, for example, pneumatically or hydraulically. These multi-function connector systems and devices can include solutions for ensuring good electrical contact is made and maintained and fluid communication is fluid-tight, thereby ensuring a continuous electrical connection and avoiding fluid leakage. In some implementations, the multi-function connector is used to connect instruments located distal to a health monitor or supply system. Examples of medical systems that can use the multi-function connector include, but are not limited to, nutritional support systems (e.g., feeding tubes), fluid distribution systems (e.g., saline, medicated suspensions for intravenous and / or subcutaneous administration, dialysis, etc.), electronic stimulation or recording systems (e.g., EKG, neurostimulation, etc.), respiratory or ventilation systems, transcatheter systems, surgical systems (e.g., robotic surgery), or hemodynamic monitoring systems.

[0138] In one non-limiting example, a multi-function connector provides electrical and fluid communication between a blood pressure cuff and a hemodynamic monitor, which further houses (or is in communication with) a pressure pump for supplying pressurized fluid and a power source for providing electrical power. The multi-function connector includes a fluid connection for communicating pressurized fluid to the cuff and an electrical connection that provides a means for supplying electrical power to and relaying signals from the cuff. In some implementations, the multi-function connector provides a connection for performing continuous blood pressure monitoring using a volume clamp method. Thus, pressurized fluid is supplied through the fluid connector to a cuff secured to a finger or other limb site, and the supplied pressurized fluid maintains the artery of the finger or other limb site in an unloaded state (i.e., maintaining a constant arterial diameter by adjusting the pressure in the cuff to counteract the systolic / diastolic pressure cycle of the artery). A photoplethysmograph (PPG) can receive an electrical input to shine light (e.g., light from one or more light emitting diodes) onto a finger or other limb site, and a sensor receives the reflected / refracted light signal after passing through an artery, thereby allowing arterial volume to be measured, which can then be transmitted via an electrical connector to a hemodynamic monitor.

[0139] The electrical connector may also be used to transmit other signals in addition to continuous blood pressure monitoring. For example, blood oxygen levels may be monitored using one or more light-emitting elements and optical sensors in a peripheral device placed on a finger or other limb site. In some implementations, the blood pressure cuff and the peripheral device for measuring blood oxygen levels are integrated together. In some of these implementations, the light-emitting element for performing blood oxygen level measurements is the same as or located adjacent to the light-emitting element for performing volume clamp blood pressure monitoring. In some of these implementations, the optical sensor for performing blood oxygen level measurements is the same as or located adjacent to the optical sensor for performing volume clamp blood pressure monitoring.

[0140] In addition to fluidic and electrical connectors, other types of connectors can be used. For example, optical connectors can be used to connect fiber optic cables when using an external light source (e.g., when the required light power is higher than can be provided by the instrument itself). In another example, electronic connectors can be used to connect ECG cables and lead wires.

[0141] 1B-1D show an example system having a multi-function connector 121 for coupling a blood pressure cuff 123 to a controller 125, which is further connected to a hemodynamic monitor (not shown). In various examples of the illustrated systems, the multi-function connector 121 can be located at the controller 125 (as shown in FIG. 1B), between the controller 125 and the blood pressure cuff 123 (as shown in FIG. 1C), or at the blood pressure cuff 123 (as shown in FIG. 1D). In each scenario, the multi-function connector 121 includes a fluid communication portion 127 and an electrical connection portion 129.

[0142] 2A and 2B show an example of a multi-function connector 201 consisting of a plug 201a and a receptacle 201b for connecting a blood pressure cuff 203 to a hemodynamic monitor (not shown). In this example, connector 201 is shown in an unconnected state, with FIG. 2A showing the blood pressure cuff 203 portion of the connector with plug 201a and FIG. 2B showing the portion of the connector with receptacle 201b for connecting to a hemodynamic monitor. Plug 201a includes electrical plug 205a and fluid plug 207a. Similarly, receptacle 201b includes electrical receptacle 205b and fluid receptacle 207b. Electrical receptacle 205b is configured to receive electrical plug 205a, and fluid receptacle 207b is configured to receive fluid plug 207a. Receptacle 201b is located in the same housing as controller 209 and extends via cable 211 to a hemodynamic monitor plug that is configured to couple to a hemodynamic monitor. Plug 201a extends via cable 215 to blood pressure cuff 203. Within cable 211 and cable 215 are electrical cords and fluid lines for transmitting power / signals and pressurized gas between the hemodynamic monitor and blood pressure cuff 203.

[0143] 3A-3I show examples of connectors that can be used in various medical devices requiring electrical connections and fluid communication. Figures 3A and 3C show connector 301, which is comprised of plug 301a and receptacle 301b. Plug 301a includes electrical plug 303a and fluid plug 305a, which are aligned adjacent to the center of the width of the electrical plug. Receptacle 301b includes electrical receptacle 303b and fluid receptacle 305b, which are recessed within the receptacle and aligned to correspond with electrical plug 303a and fluid plug 305a, respectively. As will be appreciated, the shapes and arrangements of electrical plug 303a and fluid plug 305a, and electrical receptacle 303b and fluid receptacle 305b, respectively, are asymmetric and configured so that plug 301a and receptacle 301b can mate in only one way. Furthermore, engagement of electrical plug 303a with electrical receptacle 303b can be achieved simultaneously with engagement of fluid plug 305a with fluid receptacle 305b, and vice versa.

[0144] Electrical plug 303a is generally rectangular and includes multiple electrical contacts 307a, which are recessed within the plug so as not to be exposed. Electrical receptacle 303b is generally rectangular and includes multiple electrical contacts 307b, which are configured to fit snugly within the recessed portion of electrical plug 303a so that electrical contacts 307a and 307b come into contact. Notably, the connection between electrical plug 303a and electrical receptacle 303b must be spaced a certain distance from the exposed portion to prevent electrostatic discharge (ESD). Based on the typical amounts of power and signals required in most medical devices, this connection must be airtight or spaced at least 10 to 25 mm from the exposed portion, allowing the recessed portions of receptacle 301b and electrical plug 303a to be configured so that the path to the exposed portion is longer than the ESD distance caused by the power and signals passing therethrough. Additionally, having some distance between the electrical connector and the outwardly exposed portion prevents liquids, dust, or other contaminants from reaching the contact points.

[0145] Fluid plug 305a is generally tubular in shape with a central canal 309 through which fluid can pass. Fluid receptacle 305b includes means for aligning the fluid lines of the receptacle with central canal 309 of fluid plug 305a to ensure fluid communication.

[0146] 3B and 3D show connector 331 consisting of plug 331a and receptacle 331b. Plug 331a includes electrical plug 333a and fluid plug 335a, which are aligned adjacent to a lateral portion of the width of the electrical plug. Receptacle 331b includes electrical receptacle 333b and fluid receptacle 335b, which are recessed within receptacle 331b and aligned to correspond with electrical plug 333a and fluid plug 335a, respectively. As can be seen, the shapes and arrangements of electrical plug 303a and fluid plug 305a, and electrical receptacle 333b and fluid receptacle 335b, respectively, are asymmetrical and configured so that plug 331a and receptacle 331b can engage in only one manner. Additionally, engagement of electrical plug 333a with electrical receptacle 333b may occur simultaneously with engagement of fluid plug 335a with fluid receptacle 335b, or vice versa.

[0147] Electrical plug 333a is generally rectangular and includes a plurality of electrical contacts 307a that are recessed within the plug so as not to be exposed. Electrical receptacle 333b is generally rectangular and includes a plurality of electrical contacts 337b that are configured to fit snugly within the recessed portion of electrical plug 333a so that electrical contacts 337a contact electrical contacts 337b. Notably, the connection between electrical plug 333a and electrical receptacle 333b must be spaced a certain distance from any exposed portion to prevent electrostatic discharge (ESD). Based on the typical amounts of power and signals required for most medical devices, this connection needs to be airtight or spaced at least 10-25 mm from the exposed portion so that the recessed portions of receptacle 331b and electrical plug 333a can be configured to provide a path to the exposed portion that is longer than the ESD distance caused by the power and signals passing therethrough. Additionally, having some distance between the electrical connector and the exposed portion prevents liquids, dust, or other contaminants from reaching the contacts.

[0148] Fluid plug 335a is generally tubular in shape with a central canal 339 through which fluid can pass. Fluid receptacle 335b includes a protrusion 341 with a central canal 343 that is insertable into central canal 339 of fluid plug 335a to establish fluid communication.

[0149] 3E-3I show connector 201 for connecting cable 211 to cable 215. Connector 201 includes plug 201a (see FIG. 3G) and receptacle 201b (see FIG. 3H). Plug 201a includes electrical plug 205a and fluid plug 207 within housing 361, with the fluid plugs aligned adjacent to the center of the width of the electrical plug. Receptacle 201b includes electrical receptacle 205b and fluid receptacle 207b, which are recessed within the receptacle and aligned to correspond to the dimensions of electrical plug 205a and fluid plug 207a, respectively. Receptacle 201b shares housing 363 with controller 209, thereby housing the electronic components in a compact structure. As will be appreciated, the overall shape and arrangement of electrical plug 205a and fluid plug 207a, and the overall shape and arrangement of electrical receptacle 205b and fluid receptacle 207b, respectively, are asymmetric and configured such that plug 201a and receptacle 201b can mate in only one manner. Furthermore, engagement of electrical plug 205a with electrical receptacle 205b can be achieved simultaneously with engagement of fluid plug 207a with fluid receptacle 207b, and vice versa.

[0150] Electrical plug 205a is constructed from a flexible material folded over a rigid molded component 366, forming a triangular prism-like shape with two contact surfaces, each with a plurality of electrical contacts 367a. Electrical plug 205a connects to an electrical cord 369a extending within cable 215. Wall 371 surrounds electrical plug 205a, acting as a protective shell for the plug and further providing a means for securing the electrical plug within housing 361. Wall 371 has a height greater than electrical plug edge 373, thereby ensuring that electrical contacts 367a and the distal end of the electrical plug are not exposed. Electrical receptacle 205b is a hollow triangular prism-like shape with a plurality of electrical contacts 367b on two surfaces within the cavity and configured to fit electrical plug 205a snugly within the cavity so that electrical contacts 367a and 367b make contact. Additionally, receptacle 201b may include a cavity space 375 for wall 371 that may directly surround electrical receptacle 205b. Notably, the connection between electrical plug 205a and electrical receptacle 205b must be spaced a certain distance from the exposed exterior to prevent electrostatic discharge (ESD). Based on the typical amounts of power and signals required in most medical devices, this connection must be airtight or spaced at least 10 to 25 mm from the exposed exterior. This allows the recessed portions of receptacle 201b and electrical plug 205a walls 371 to be configured such that the path to the exposed exterior is longer than the ESD distance caused by the power and signals passing therethrough. Furthermore, having some distance between the electrical connector and the exposed exterior prevents liquids, dust, or other contaminants from reaching the contacts.

[0151] Fluid plug 207a has a generally tubular shape with a central canal 376 that allows fluid to pass through it and provides connection to a fluid line 377a that extends within cable 215. Fluid plug 207a includes a lip seal 378 at its distal end, which may be a flexible, soft material (e.g., rubber, silicone, etc.) that may conform to another surface when mated to ensure leak-tight fluid communication through a central orifice within the lip seal. Fluid receptacle 207b may include a surface with a central orifice within a recessed portion to ensure fluid communication with a fluid line 377b that extends within cable 211.

[0152] Controller 209 may include a printed circuit board 379, which may be in communication with electrical receptacle 205b and / or an electrical cord extending through cable 211. Housing 363 is held together via screws or any other means for constructing the housing. A faceplate 381 may be provided to cover any screw heads or other orifices to attenuate ESD and may be constructed from any non-conductive material.

[0153] Various types of seals can be used for the fluid connector, including, but not limited to, lip seals, radial seals, gaskets, and washers. As discussed above, in the example systems of FIGS. 3C and 3D, a lip seal is provided on the fluid plug. Alternatively, a lip may be provided on the fluid receptacle (FIG. 3I) or on both the fluid plug and the fluid receptacle. Similarly, a radial seal or gasket may be provided on the fluid plug, the fluid receptacle, or both the fluid plug and the fluid receptacle. A washer (particularly a flexible soft washer) may be provided between the fluid plug and the fluid receptacle.

[0154] In some implementations, sealing features are provided internally (e.g., when a complement is inserted into the fluid port), externally (e.g., when the fluid port is inserted into its complement), or both internally and externally of the fluid port, which allows for axial and / or radial scaling around the fluid port to prevent leakage and / or allow for tolerances between connector components.

[0155] Connectors as described may have a variety of configurations and are not limited to the examples presented in FIGS. 3A-3I. In some embodiments, a connector may have multiple electrical contacts, which may be located on one or more sides of the connector. Additional contacts may be implemented to allow additional instruments, sensors, or devices to be connected to a power source or monitor, thereby expanding the capabilities of the medical monitoring system. Furthermore, each electrical connector may include any number of electrical contacts that can be fitted onto the connector, including up to one, two, four, six, eight, ten, twelve, fifteen, twenty, twenty-five, or more electrical contacts. Electrical connectors may be housed within housings having nonlinear shapes (e.g., triangular, circular, etc.), which provide additional sides or surfaces for locating electrical contacts. Alternatively, the connector can be symmetrical (e.g., with electrical connectors located above and below a central fluid connector), eliminating the need to distinguish between "top" and "bottom" connectors; the connector can be mated in either orientation. A common example of this configuration is a USB-C port that can be inserted in either orientation. The connector can be utilized for a variety of operations, such as blood pressure monitoring, pulse oximetry, chemical analysis or probes, moisture detection, conductance measurement or sensing, and / or any other operation for monitoring an individual's physiological parameters. Examples of devices that can be connected to a monitor or power source include a blood pressure cuff (e.g., a finger cuff, wrist cuff, arm cuff, etc.), electrodes or leads, light emitting elements, optical sensors, thermodilution sensors, pressure sensors, flow sensors, or any other sensors.

[0156] 4A and 4B provide further detailed views of the electrical plug 363a and electrical receptacle 363b and the connection therebetween. The electrical plug 363a is constructed from a flexible material 401 folded over a rigid molded component 373; when disengaged, the flexible material 401 is not under tension and has some flexibility. The electrical plug has two contact surfaces 403 on a single surface of the flexible material 401, each having multiple electrical contacts 367a and configured to be positioned on a different facing surface of the rigid molded component 373 when folded over. The electrical receptacle 363b may be constructed from a molded material 405 having a cavity 407 shaped to fit over the rigid molded component 373. The electrical contacts 367b of the electrical receptacle 363b are disposed within the cavity 407 and may be spring-loaded. When electrical plug 363a and electrical receptacle 363b are mated (FIG. 4B), flexible material 401 conforms to cavity 407 and molded part 373, ensuring proper contact between electrical contacts 367a and 367b.

[0157] Various connector implementations can be arranged in a variety of configurations. Figures 5A-5G show additional examples of connector arrangement types that can be utilized. Such arrangements include various options: perpendicular orientation (e.g., Figures 5A and 5B), side-by-side orientation (e.g., Figures 5C-5F), and radial orientation (e.g., Figure 5G). The illustrated examples are intended to be illustrative of electrical, fluidic, electronic, optical, and any other type of connector arrangement, but are not intended to be limiting. For example, the positions of some connectors may be varied, e.g., one connector may be aligned so that it is offset to one side of another connector rather than aligned midpoint (as shown in Figures 5A and 5B). Similarly, in some side-by-side arrangement embodiments (e.g., Figures 5D-5F), one or more connectors may be longer (or shorter) than the other connectors to achieve asymmetry. Additionally, while the examples in Figures 5D-5F show parallel arrangements forming angles of approximately 180° (Figure 5D), approximately 90° (Figure 5E), and approximately 120° (Figure 5F), various other angles are possible and can be modified for a particular application or design.

[0158] Some connector implementations have asymmetries that result in a unique shape and “key” effect to prevent improper mating (e.g., backward mating). In some implementations, additional features are provided to enhance the asymmetry and / or prevent misalignment when mating the plug with the receptacle. Such features include protrusions, fins, pins, and / or other geometric features that can prevent incorrect insertion of the plug into the receptacle and / or guide the alignment of the plug. For example, FIGS. 6A and 6B present an example connector 601 that includes a plug 603a that incorporates a protruding pin 605 that complements a groove in a receptacle 603b to achieve a keying effect.

[0159] Some connector implementations have specific geometries to aid insertion, such as geometries for aligning a plug with a complementary receptacle. Such implementations allow the connectors to be partially engaged, thereby aiding alignment before full engagement ( FIG. 7 ). These implementations can prevent damage to delicate contacts that are prone to bending or breaking if misaligned. To allow partial insertion, the connector 701 can include a pin that allows engagement in only one orientation. The plug 703 a can partially engage the receptacle 703 b and then rotate about the pin until the plug reaches a correctly aligned position, at which point full engagement can be established. Rather than a separate pin, a port can protrude or extend longitudinally (i.e., along the distal-proximal axis) within the connector to enable insertion into and rotation about the port. This extended port can be a fluidic connector, an electrical connector, or any other type of connector suitable for rotation. Generally, any type of connector can have rounded protrusions and ports suitable for rotation.

[0160] Various shapes of pins and / or ports suitable for rotation are available. Such shapes can be round, circular (e.g., a Reuleaux triangle), or another configuration with a cross-sectional shape of a constant width. Such shapes can be rotated within a receptacle to allow alignment of the connector (e.g., alignment of any ports and contacts, such as fluid ports and electrical contacts). In some implementations, an alignment pin or port has an area larger than at least one dimension of every other receptacle except itself, thereby preventing the alignment pin or port from being inserted into other receptacles. These implementations can help prevent or avoid damage to delicate contacts that may be damaged if misaligned.

[0161] To maintain the connection between complementary parts of the receptacle, some embodiments may use various mechanisms, such as, for example, pins, rings, springs, balls, clips, clasps, or any other mechanism for maintaining a connection. In certain embodiments, such mechanisms further provide tactile feedback to the user to indicate complete and / or proper connection of the components. The pins comprise pogo pins or other spring-loaded structures that can lock into corresponding recesses or grooves located in a portion of the plug. Similarly, rings and / or springs can be used in a manner similar to the pins, and the rings and / or springs can fit into grooves located in some or all of the connector. For example, FIGS. 8A and 8B present an example of a connector with a retention mechanism. Plug 801a has a fluid plug 803a that protrudes from the plug body and forms a port. Fluid plug 803a includes a radial groove 805a configured to “click in” and be retained within the receptacle by engaging one or more pins, springs, balls, rings, radial lips, and / or another mechanism. As shown in the example of FIG. 8B, receptacle 803b includes a spring-loaded ball pin 805b that engages in radial groove 805a so that plug 803a clicks into the receptacle.

[0162] Various other implementations of connectors may use clip or clasp mechanisms for retention and / or tactile feedback of insertion. In FIGS. 9A and 9B, examples of connectors using retention clips are presented. The connector in FIG. 9A includes a plug 901a with a protruding ridge 903a configured to engage a flexible retention clip 903b of a receptacle 901B. Similarly, the connector in FIG. 9B includes a plug 931a with a flexible retention clip 933a configured to engage a groove 933b of a receptacle 931b. Thus, various implementations of connectors may use retention clips that apply an outward force (e.g., FIG. 9A) or an inward force (e.g., FIG. 9B). In some implementations, retention clip 951 may be manufactured as an integral component of electrical contacts 953, as shown in FIG. 9C, or retention clip 971 may be manufactured as an integral component of molded component 973, as shown in FIG. 9D.

[0163] In several implementations, a connector is used to connect the blood pressure cuff to a hemodynamic monitor. FIGS. 10A and 10B show an example of a blood pressure cuff 203 used for continuous blood pressure monitoring. The blood pressure cuff 203 is configured to be attached to a patient's extremity, such as a finger, thumb, or toe. The blood pressure cuff 203 may include an inflatable bladder 1001 having an inflation chamber formed between an interface membrane 1003 and a back membrane 1005. The interface membrane 1003 may include a urethane material. The back membrane 1005 may include a PVC material. The urethane material may be thinner and / or more flexible than the PVC material. The interface membrane 1003 and the back membrane 1005 may be sealed along their outer edges to prevent fluid leakage. Additionally, the bladder 1001 may further include a tail portion 1001a. Tail portion 1001a may be formed from a portion of interface membrane 1003 and / or back membrane 1005. If tail portion 1001a is formed from both membranes 1003 and 1005, membranes 1003 and 1005 may be sealed together, for example, along the periphery of tail portion 1001a. The inflation chamber does not extend to tail portion 1001a. The inflation chamber may be coupled to fluid line 377a via fluid port 1009. The fluid line may extend within and along cable 215 to a connector (not shown), such as connector 201. Thus, a pump system may supply pressurized fluid to the inflation chamber via fluid line 377a, thereby enabling the inflation chamber to inflate and deflate to perform blood pressure monitoring using the volume clamp method.

[0164] The blood pressure cuff 203 may further include a light emitting element 1011 for emitting light onto the patient's limb site and an optical sensor 1013 for detecting an optical signal emitted from the light emitting element 1011 (e.g., an optical signal that has passed through the limb site and / or has been reflected / refracted by passing through the limb site). In some implementations, the light emitting element 1011 and the optical sensor 1013 function in combination to form a photoplethysmograph for measuring the diameter of an artery in the patient's limb site. The light emitting element 1011 and the optical sensor 1013 can also be used for other signal acquisition, such as quantifying blood oxygen levels. To perform these tasks, the light emitting element 1011 can emit two or more discrete wavelength bands within the visible and infrared ranges, depending on the implementation. In some implementations, the light emitting element 1011 emits red and infrared wavelength bands, which may be useful for performing both photoplethysmography and blood oxygen saturation measurements. Each of the light emitting elements 1011 and light sensors 1013 may be connected to an electrical cord 369a that extends within and along the cable 215 to a connector (not shown). Thus, a power source and a hemodynamic monitor may be in electrical connection with the light emitting elements 1011 and light sensors 1013, allowing these devices to be powered and to transmit signals for performing blood pressure monitoring.

[0165] The light emitting elements 1011 and light sensors 1013 may be disposed on a circuit mounting membrane 1017, which may be a flex circuit. The light emitting elements 1011 and / or sensors 1013 may each protrude a certain height or heights from one or more surfaces of the membrane 1017. The membrane 1017 may be part of a flex circuit 1016 comprising the cord 369a. Electrical connection of the light emitting elements 1011 and light sensors 1013 to the electrical cord 369a may be made on either side of or within the membrane 1017, which may prevent contact between the back membrane 1005 of the inflatable bladder 1001 and any electrical wiring connecting the sensors 1013 and light emitting elements 1011 to the cord 369a.

[0166] The membrane 1017 may be attached to the inflatable bladder 1001. This attachment can be via heat sealing, adhesive, or other means. The membrane 1017 may be substantially completely attached to the back membrane 1005. The periphery of the membrane 1017 may be aligned with the inflatable bladder 1001. Alternatively, the periphery of the membrane 1017 may be attached along the periphery of the inflatable bladder 1001, including the membranes 1003, 1005. The back membrane 1005 may include one or more through-holes 1019. The number of through-holes 1019 can correspond to the number of light sources and / or light-emitting elements, but this is not required. The through-holes 1019, when assembled with the membrane 1017, can be aligned with the light emitting elements 1011 and light sensors 1013, allowing each of these light emitting elements 1011 and light sensors 1013 to pass through the through-hole (to the extent permitted by their protrusion height) and abut against the contact surface 1003. The contact surface 1003 can be transparent to allow light to pass through. The contact surface 1003 can be sealed to the back surface 1005 around the periphery 1019a of the hole(s) 1019. Advantageously, the through-holes 1019 allow the light emitting elements and / or light sensors to protrude further from the membrane 1017 toward the patient's extremity region received within the bladder 1001. This arrangement allows for enhanced emission and / or reception of red wavelengths. In an alternative configuration, the contact surface 1003 may further include through-holes aligned with the through-holes 1019, which may likewise be sealed around the through-holes in the contact surface 1003. This arrangement may facilitate even closer proximity or contact between the patient's limb site and the sensor and / or light emitting element. The back membrane 1005 and / or surface 1017 may be a dark color (e.g., black, dark gray, navy blue, etc.), which may prevent reflection of light signals in the red wavelength spectrum and reduce noise detected by the light sensor 1013. The membrane 1017 may be adhered to the bladder 1001 at a location such as the back membrane 1005.

[0167] Components of the blood pressure cuff 203 (e.g., light emitting element 1011, optical sensor 1013, fluid port 1009, etc.) can be connected to the wiring and lines of the cable 215 (e.g., electrical cord 369a and fluid line 377a) at an angle that reduces the amount of contact between the cable and the patient. If the blood pressure cuff 203 is connected at a 90-degree angle (as determined based on the nearest edge of the blood pressure cuff), the cable may become entangled in the patient's hand or foot. Therefore, in various implementations, the cable 215 is connected to the blood pressure cuff 203 at an angle between 30 and 65 degrees (as determined based on the nearest edge of the blood pressure cuff). To achieve this angle, the cord 369a is connected to the surface 1017 at an appropriate angle. Similarly, the fluid port 1009 is connected to the bladder 1001 at an appropriate angle. The flexible material forming the cord 3609a and the surface 1017 can further include a bent portion 1032. The bent portion 1032 can adjust the angle between the surface 1017 and the cord 369a. The surface 1017 is manufactured as a flex circuit at a second angle (e.g., 90 degrees), but the bent portion 1032 allows the surface 1017 to be at a first angle (e.g., relative to the cord 369a) when assembled to the cuff 203. Additionally, a stabilizer band 1021 can be provided to strengthen the connection between the cable 215 and the blood pressure cuff 203.

[0168] The blood pressure cuff 203 includes an inflatable portion (i.e., an inflatable bladder 1001) and a non-inflatable portion 1023. The non-inflatable portion may include a first end 1023a and a second end 1023b. The tail portion 1001a may be adhered to the non-inflatable portion 1023, for example, at or adjacent to the first end 1023. When the blood pressure cuff 203 is positioned on the limb site, the inflatable bladder 1001 and the non-inflatable portion 1023 form a closed cuff by surrounding the limb site. In this configuration, the first end 1023a may be wrapped around the limb site and coupled to the second end 1023b, such as by overlapping the second end 1023b. The inflatable bladder 1001 may surround the limb site from about halfway to the entire circumference. In some implementations, the inflatable bladder 1001 does not completely enclose the limb site when worn, which can provide greater comfort to the patient. The non-inflatable portion 1023 can further include overlapping portions on the ends 1023a, 1023b, which allows the inflatable bladder 1001 and non-inflatable portion 1023 to overlap the limb site more than one time and up to two times when worn. The overlapping portions can include various fastening and securing means, such as, for example, corresponding hook-and-loop fasteners 1020 or adhesives. In one example, the first end 1023a can include a hook-and-loop component 1020 on a first surface of the non-inflatable portion 1023, and the second end 1023b can include a corresponding hook-and-loop component (not shown) on a back surface of the non-inflatable portion 1023. The corresponding hook-and-loop component can extend along the back surface for a length that allows for various fastening positions for coupling with the hook-and-loop component 1020. In one example, this corresponding hook and loop fastener (not shown) on the back surface can extend from the second end 1023a to or adjacent to the first end 1023a, or can extend to at least a midpoint between the first end 1023a and the second end 1023b.

[0169] The first end 1023a may include a gripping tab 1020a. The gripping tab 1020a may be free of fastening means 1020, such as a hook-and-loop fastener or Velcro®. In this manner, the absence of fastening and fastening means 1020 allows the gripping tab 1020a to be freely and easily grasped when the first end 1023a is attached to and overlaps the second end 1023b. Advantageously, this may make it easier for a user to open and adjust the hoop formed by the non-inflatable portion 1023 for removal or adjustment.

[0170] During volume clamping, the fluid pressure within the bladder 1001 is rapidly adjusted to track the blood pressure within the arteries of the limb site. To accurately measure and adjust this pressure, the non-inflatable portion 1023 forms the outer shell of the non-stretchable cuff 203, including when formed into a hoop as described above. The hoop can therefore provide structural rigidity to the inflatable portion 1001. Advantageously, the hoop formed by portion 1023 can be of a different material than the inflatable portion 1001. By forming the inflatable portion 1001 and the non-inflatable portion 1023 as separate and independent materials (which may, however, be directly or indirectly connected by one or more other components and / or adhesives), unwanted stretching of the hoop due to pressurizing the bladder 1001 is avoided, which could induce measurement errors and / or system response time problems. Furthermore, the materials selected for each of portions 1001 and 1023 can be optimized for their specific functions.

[0171] The blood pressure cuff 203 may further include an extension tab 1025. The extension tab 1025 may be used to align the finger so that the light emitting element 1011 and the light sensor 1013 are properly positioned when worn. The extension tab 1025 may include a pivot point around which it folds over to cover the limb site when worn. The extension tab 1025 may further include an attachment portion 1027. The attachment portion 1027 may be folded over to cover the limb site (e.g., to hide the fingertip). The attachment portion 1027 may be attached to the non-inflatable portion 1023. The attachment portion 1027 may include various fastening and securing means, such as, for example, a hook-and-loop fastener 1022 or adhesive. In one example, the hook-and-loop component 1022 may be attached to the same hook-and-loop component 1020 on the back surface of the non-inflatable portion 1023. Advantageously, this arrangement reduces the number of components required to assemble the cuff 203. The hook and loop component located on the underside of the non-inflatable portion 1023 can have a constant width across which the hook and loop component 1022 can be attached in various positions.

[0172] The cuff 203 may further include a coil 1031. The coil 1031 may be biased to curl into a closed or semi-closed hoop. The inner surface of the coil may be bonded to one side (such as two ends) of the material of the membrane 1017, or alternatively may be bonded directly to the back membrane 1005, such as on the tail portion 1001a. The outer surface of the coil 1031 may be bonded to the non-inflatable portion 1023, biasing the non-inflatable portion into the hoop structure. In one example, the non-inflatable portion 1023 may be bonded to the tail portion 1001a with a portion of the coil 1031 sandwiched therebetween.

[0173] 11 shows an exploded view of cable 215, illustrating the connection between the end of blood pressure cuff 203 and connector 201. Cable 215 includes an outer sheath 1101 for housing electrical cord 369a and fluid line 377a. Fluid line 377a thus connects fluid port 1009 and blood pressure bladder 1001 to fluid plug 207a, and electrical cord 369a connects light emitter 1011 and optical sensor 1013 to electrical plug 205a. Among other things, light emitter 1011, optical sensor 1013, surface 1017, electrical cord 369a, electrical plug 205a, and electrical contacts 367a can be manufactured as a single component, thereby alleviating the need for an additional electrical connector between blood pressure cuff 203 and connector 201.

[0174] 12A-12G provide an example of how to assemble the electrical components of blood pressure cuff 203 to cable 215. One advantage of electrical plug 205a is that it includes a foldable, flexible material. This foldable capability can be utilized to facilitate assembly of cable 215.

[0175] 12A, an elongated instrument 1201 is shown having a tubular head 1203 with a hollow portion 1204, which is coupled to a shaft 1205. The elongated instrument extends through the outer sheath 1101 so that the tubular head 1203 is exposed. Also shown is an electrical plug 205a and an electrical cord 369a, which are manufactured as a single unitary component with the light emitter and optical sensor of the blood pressure cuff. The electrical plug 205a may include a microchip 1207, which may be positioned along the centerline of the electrical plug. Also shown is a rod 1209.

[0176] In Figure 12B, the electrical plug 205a is rolled into a tubular shape. A rod 1209 may be used to assist in rolling the electrical plug 205a. In Figure 12C, the electrical plug 205a is inserted into the cavity 1204. In Figure 12D, with the electrical plug 205a located within the cavity 1204, the outer sheath 1101 is pushed over the elongated instrument 1201 until the tubular head 1203 passes completely through to the other side of the outer sheath. Or, alternatively, the elongated instrument is pulled through the outer sheath until the tubular head passes completely through to the other side.

[0177] FIG. 12E shows an example of the result after the electrical plug 205a has completely passed through the outer sheath 1101. The electrical components of the blood pressure cuff 203 (e.g., light emitting element 1011, optical sensor 1013, surface 1017, etc.) are located on one end of the outer sheath 1101, and the electrical plug 205a is located on the other end. Also shown in FIG. 12E is a rigid molded component 366. The electrical plug 205a is folded over the rigid molded component 366 to form a two-sided plug, as shown in FIGS. 12F and 12G. Thus, the electrical plug 205a includes two sides with electrical contacts 367a that are in communication with the microchip 1207 and the electrical cord 369a. The electrical plug can be snapped and secured to the rigid molded component 366 by snaps 1211 or other fastening means.

[0178] 13A-13D present examples of connector receptacle housings and assemblies that further include a controller. Typically, the assembly requires the integration of two or more molded parts. Furthermore, in some implementations, the amount of assembly is minimized, and the amount of sealing required for airtight and liquid tightness, as well as for reducing the ESD discharge area and / or contaminant ingress area, is minimized. Furthermore, in some implementations, the housing surrounding the receptacle is strong enough to prevent crushing of the internal components (e.g., if stepped on) and is tactile and easy to handle, facilitating the coupling of a plug into the receptacle. In FIGS. 13A and 13B, an example of a housing assembly is presented, which includes a controller and a receptacle within two outer shell components. These two outer shell components have a longitudinal division between them. 13C and 13D are an example of a housing assembly that includes a controller and a receptacle within two outer shell components that have a short, angled radial split.

[0179] 13A and 13B, the receptacle 201B and the controller 209 are located within an outer shell housing 1301 formed by upper and lower shell components 1301a and 1301b, each of which comprises a hard molding material. The upper and lower shell components 1301a and 1301b are joined at an axial centerline to form an axial surface coupling 1303. The upper and lower shell components 1301a and 1301b and the internal components located therein can be fastened and / or secured by any suitable mechanism, such as screws, snaps, rivets, adhesives, etc. The outer shell housing 1301 can form a generally rectangular parallelepiped shape having at least one face 1305 comprising the receptacle 201b. As will be readily understood, other geometric shapes, such as a triangular prism, a pentagonal prism, or a hexagonal prism, can also be used. Receptacle 201b may be manufactured to form surface 1305 when assembled with upper and lower shell components 1301a, 1301b. At the opposite end of surface 1305 may be strain relief 1307 that connects outer shell housing 1301 and the components located therein to cable 211. Strain relief 1307 may be a semi-flexible molded material that may provide some flexibility, thereby relieving stress at the connection points between the electrical components and fluid lines in outer shell housing 1301 and the electrical cords and fluid lines 377b that run in and along cable 211.

[0180] 13C and 13D present substantially the same components and features as FIGS. 13A and 13B, with the exception of the outer shell housing. In FIGS. 13C and 13D, the outer shell housing 1351 is formed by an elongated sleeve 1351a and an end cap 1351b, each comprising a hard molding material. The elongated sleeve 1351a and the end cap 1351b may be joined at an angled radial line to form an angled radial planar joint 1353. Among other things, the angled radial planar joint 1353 significantly shortens the parting line, making sealing easier and reducing assembly costs and ESD-related risks. Using the outer shell housing 1351, internal components such as the controller 209, electrical cords, and fluid lines may be inserted into the sleeve by sliding the elongated sleeve 1351a over the internal components. The elongated sleeve 1351a, lower end cap 1351b, and internal components therein can be fastened and / or secured by any suitable mechanism, such as, for example, screws, snaps, rivets, adhesives, and the like.

[0181] In some implementations, a unitary housing (i.e., no split) is used. To this end, the housing, strain relief, and receptacle face are configured to form a seal. At one end, the receptacle face fits into the housing to form a seal, and at the other end, the strain relief fits into the housing to form a seal. The strain relief and internal components are pulled through the housing, placing the receptacle face in place. Once pulled into their final position, the strain relief, receptacle housing, and / or internal components can be secured in place. One method for securing these components in place is to use a set of snaps, springs, pins, or clips that secure the housing when the internal components and strain relief are pulled into place (similar to the securing mechanism used for the plug in FIGS. 8A-9D). Other means of securing the internal components and strain relief can also be used, such as screws, rivets, adhesives, etc.

[0182] The medical monitoring system may be comprised of a computing device or system, such as, for example, a dedicated device, a desktop computer, a tablet, a mobile device, a laptop computer, a notebook computer, a server system, and / or any other device capable of performing computational processes related to connected medical instruments (e.g., blood pressure monitoring via a blood pressure cuff). FIG. 14 illustrates an example of relevant components of a computing device that may perform these processes. As can be readily understood, a computing device or system may include other components than those illustrated in FIG. 14. The computing device 1400 may include a processor system 1402 and a memory 1404. The memory 1404 may be non-volatile and / or volatile memory, and the processor system 1402 may be a processor, microprocessor, controller, or combination of processor, microprocessor, and / or controller that executes instructions stored in the memory 1404. Such instructions stored in the memory 1404, when executed by the processor system, may instruct the processor to perform one or more features, functions, methods, and / or steps depending on one or more medical instruments connected to the medical monitoring device. Any input information or data may be stored in memory 1404. Computing device 1400 may additionally or alternatively include hardware and / or firmware that can instruct processor system 1402 to perform these processes.

[0183] Computing device 1400 may include a network device 1406 for enabling communication (wired, wireless, etc.) with another device, such as via a network, near field communication, Bluetooth, infrared, radio frequency, and / or other suitable communication system. Such a system may be useful for receiving data, information, or input (e.g., data from one or more sensors, etc.) from another computing device and / or for transmitting data, information, or output (e.g., vital signs) to another device.

[0184] The computing device 1400 may include a controller, which may be housed with the computing device or housed separately (e.g., in a connector housing, etc.). The computing device 1400 and the controller may share the same processor, memory, power supply, and / or other electronic or electrical components.
