Intravenous (IV) therapy may refer to a medical technique that is used to deliver fluids, medications, and/or nutrition directly into a body of a patient via an IV catheter inserted into a vein at an IV insertion site. IV therapy may be used for rehydration, to provide nutrition to a person who cannot consume food or water by mouth, and/or to administer medications or other medical therapy, such as blood products or electrolytes.
In some instances, components of an IV catheter for IV therapy may require a disinfection process. The disinfection process may involve the use of a topical disinfectant on the skin of the patient following a saline flush of the IV catheter at the IV injection site. For example, the disinfection process for an IV catheter may be to remove the IV catheter and components of the IV catheter and treating with a topical disinfectant, such as rubbing alcohol.
However, there may be significant drawbacks to removing the IV catheter and components of the IV catheter. For instance, removing the IV catheter and components of the IV catheter may increase exposure of these areas to potential infectious agents. In addition, it may also be important to minimize movement of the IV catheter and components of the IV catheter. In some instances, if the IV catheter is not properly secured in place, the IV catheter may be displaced from an intended location. Further, repeated movement of the IV catheter, to correctly position the IV catheter, can cause irritation of a blood vessel, disrupt proper introduction of medications to the patient, and/or increase the potential for bleeding or infection at the IV insertion site. If extensive movement occurs, the IV catheter may come out of the patient, interrupting delivery of medication and requiring re-insertion, potentially with a requirement for hospitalization of the patient. Accordingly, it is beneficial to use other methods of disinfection for catheter lines to remove risk of internal infection.
Therefore, there is an increasing need for disinfecting IV catheters, without the potential of introducing adverse effects to the patient.
Accordingly, provided are improved systems, devices, products, apparatus, and/or methods for an IV catheter disinfecting device.

In some non-limiting embodiments, disinfecting light source 104 may include one or more devices that are configured to provide light to disinfect a surface. For example, disinfecting light source 104 may include a device that is configured to provide light in a wavelength that is configured to disinfect a surface. In this way, disinfecting light source 104 may provide for disinfection (e.g., antimicrobial disinfection) of a surface (e.g., a surface of an IV catheter), based on the use of disinfecting light source 104. In some non-limiting embodiments, disinfecting light source 104 may include a light emitting diode (LED), a plurality of LEDs (e.g., an array of LEDs), a light bulb, a light-emitting electrochemical cell (LEC), a laser, and/or the like. In some non-limiting embodiments, disinfecting light source 104 may include one or more light emitting elements. For example, disinfecting light source 104 may include a plurality of emitting elements, where each light emitting element is an LED, a light bulb, an LEC, a laser, and/or the like.
In some non-limiting embodiments, extension line 114 may allow fluid to flow from a fluid source connected to extension 114 through extension line 114 and into a catheter 116. As further shown in
In some non-limiting embodiments, IV catheter disinfecting device 100 may include one or more optical fibers. For example, IV catheter disinfecting device 100 may include one or more optical fibers, where disinfecting light source 104 is configured to provide light to the one or more optical fibers and the one or more optical fibers are configured to carry the light received from disinfecting light source 104 (e.g., carry the light received from disinfecting light source 104 to a location). In some non-limiting embodiments, an end of the one or more optical fibers may include a light diffuser element.
In some non-limiting embodiments, the one more optical fibers may be positioned in fiber optic connector 110 such that the one or more optical fibers may receive light provided by disinfecting light source 104 (e.g., when disinfecting light source is coupled to fiber optic connector 110) and transmit the light at certain positions along a length of the one or more optical fibers and/or at end of the one or more optical fibers. In some non-limiting embodiments, IV catheter disinfecting device 100 may have a first optical fiber and a second optical fiber. The first optical fiber may be configured to transmit light from disinfecting light source 104 to a fluid channel of catheter 116. In some non-limiting embodiments, the second optical fiber may be used for feedback to a sensor to detect a disconnection in the first optical fiber. In some non-limiting embodiments, the second optical fiber may also be used to provide feedback to a sensor or controller to adjust an intensity of light emitted from disinfecting light source 104.
In some non-limiting embodiments, disinfecting light source 104 may provide antimicrobial blue light (aBL), which may include electromagnetic radiation having a wavelength between 400-470 nm. Additionally or alternatively, disinfecting light source 104 may provide electromagnetic radiation having a wavelength between 630-680 nm, which may be referred to as red light. Additionally or alternatively, disinfecting light source 104 may provide electromagnetic radiation having a wavelength between 10-400 nm, which may include electromagnetic radiation in the ultraviolet (UV) spectrum. For example, disinfecting light source 104 may provide electromagnetic radiation having a wavelength between 100-280 nm (e.g., the UVC spectrum), electromagnetic radiation having a wavelength between 280-315 nm (e.g., the UVB spectrum), and/or electromagnetic radiation having a wavelength between 315-400 nm (e.g., the UVA spectrum).
In some non-limiting embodiments, disinfecting light source 104 may have a sensor (not shown) which may include one or more devices that are configured to detect a disconnection (e.g., a cut, a break, etc.) in the optical fiber or a disconnection of disinfecting light source 104 from fiber optic connector 110. For example, the sensor may be incorporated into disinfecting light source 104 and include one or more devices that are configured to receive feedback from an optical fiber to determine a discontinuation in the light. In this way, in the case that a disconnection is detected, disinfecting light source 104 may not produce light. In some non-limiting embodiments, the sensor may detect a disconnection based on time, color, and/or conductivity (e.g., a difference in conductivity). In some non-limiting embodiments, sensor may include one or more photoelectric sensors, one or more laser sensors, one or more ultrasonic sensors, one or more color sensors, one or more contact sensors, one or more proximity sensors, one or more image sensors, and/or the like. In some non-limiting embodiments, IV catheter disinfecting device 100 may include one or more sensors.
In some non-limiting embodiments, disinfecting light source 104 may be controlled based on a sensor. For example, a controller (not shown) may receive a signal from the sensor and the controller may cause disinfecting light source 104 to activate or deactivate based on the signal received from the sensor.
In some non-limiting embodiments, IV catheter disinfecting device 100 may include safety device associated with an optical fiber, such as a sensor that is used to determine if there is a discontinuation in an optical fiber. In one example, the sensor may be configured to determine an amount of time during which light traveled along an optical fiber. In such an example, the sensor may transmit a signal includes data associated with the amount of time during which the light traveled along the optical fiber and the controller may receive the signal from the sensor. Accordingly, the controller may determine whether the amount of time during which the light traveled along the optical fiber satisfies a threshold. In some non-limiting embodiments, the threshold may include a threshold value of an amount of time based on a predetermined amount of time for light to travel along the length of the optical fiber. Further, the controller may determine a control operation based on determining whether the amount of time during which the light traveled along the optical fiber satisfies the threshold. In some non-limiting embodiments, the controller may determine a control operation for disinfecting light source 104 based on determining that the amount of time during which the light traveled along the optical fiber satisfies the threshold. For example, the controller may activate (e.g., continue to activate, forego deactivating, etc.) disinfecting light source 104 based on determining that the amount of time during which the light traveled along the optical fiber satisfies the threshold. In some non-limiting embodiments, the controller may determine a control operation for disinfecting light source 104 based on determining that the amount of time during which the light traveled along the optical fiber does not satisfy the threshold. For example, the controller may deactivate (e.g., prevent from activating, forego activating, etc.) disinfecting light source 104 based on determining that the amount of time during which the light traveled along the optical fiber does not satisfy the threshold.
As referred to herein, a controller may include a device configured to control disinfecting light source 104. For example, the controller may include a device configured to control (e.g., control the activation and/or deactivation of) disinfecting light source 104 based on information received from one or more sensors. In some non-limiting embodiments, the controller may include a processor, such as a central processing unit (CPU), a microcontroller, an integrated circuit (IC), and/or the like. In some non-limiting embodiments, the controller may include a switch device, such as an electrical switch.
In some non-limiting embodiments, disinfecting light source 104 may be controlled based on a time interval (e.g., a predetermined time interval, a time interval associated with a disinfection process, etc.). In one example, a controller may cause disinfecting light source 104 to activate based on an initiation of the time interval (e.g., based on the activation of a time counter for the time interval). Additionally or alternatively, the controller may cause one or more light elements of disinfecting light source to deactivate based on an expiration of the time interval. In some non-limiting embodiments, disinfecting light source 104 may be configured to be deactivated based on an expiration of the time interval. In some non-limiting embodiments, the time interval may be selected by a user of IV catheter disinfecting device 100 (e.g., a patient, a doctor, etc.). For example, the time interval may be selected by the user via a user input device, such as a physical component (e.g., a dial, a switch, a button, etc.) or a user interface (e.g., a graphical user interface, an element of a user interface, etc.). In some non-limiting embodiments, the time interval may be a predetermined time interval (e.g., a preprogrammed time interval) that is stored in a memory of IV catheter disinfecting device 100 and that is retrieved by a controller prior to activation of disinfecting light source 104.
In some non-limiting embodiments, disinfecting light source 104 may be controlled based on a time interval and a sensor. For example, a controller may prevent the initiation of the time interval (e.g., the time interval during which disinfecting light source 104 is activated) unless a signal (e.g., an activation signal) is received from the sensor. In some non-limiting embodiments, the controller may initiate the time interval based on receiving the signal from the sensor. In another example, the controller may prevent the initiation of the time interval unless a signal is received from the sensor. In some non-limiting embodiments, the controller may initiate the time interval based on receiving a signal from the sensor that indicates that disinfecting light source 104 is coupled to fiber optic connector 110.
In some non-limiting embodiments, disinfecting light source 104 may be controlled based on a predetermined sequence. For example, one or more light elements of disinfecting light source 104 may be activated and/or deactivated based on the predetermined sequence. In some non-limiting embodiments, disinfecting light source 104 may be controlled based on an input from a user. For example, one or more light elements of disinfecting light source 104 may be activated based on the input from the user. In some non-limiting embodiments, the input from the user may overwrite a predetermined sequence during which disinfecting light source 104 may be activated. For example, one or more light elements of disinfecting light source 104 may be activated based on the predetermined sequence and during the predetermined sequence, an input from the user is received.
As shown in
In some non-limiting embodiments, IV catheter disinfecting device 100 may include an integrated safety interlock device. For example, disinfecting device 100 may include an integrated safety interlock device that is configured to prevent disinfecting light source 104 from operating unless disinfecting light source 104 is coupled (e.g., properly coupled) to fiber optic connector 110. In some non-limiting embodiments, the integrated safety interlock device may be configured to prevent disinfecting light source 104 from operating unless disinfecting light source 104 is coupled to fiber optic connector 110 such that all light provided by disinfecting light source 104 is transmitted to an optical fiber without allowing any light to escape to a surrounding environment of disinfecting light source 104. In this way, the integrated safety interlock device may prevent the light provided by disinfecting light source 104 from shown on unintended locations, including sensitive areas of users of IV catheter disinfecting device 100. In some non-limiting embodiments, the integrated safety interlock device may be a component of a connection between fiber optic connector 110 and disinfecting light source 104. In some non-limiting embodiments, the integrated safety interlock device may include a contact sensor, a contact switch (e.g., a sensor connected to a switch that is open state or a closed state based on whether contact is detected), a conductivity sensor, and/or the like.
