[0009] The detailed descriptions below are intended to describe various configurations of the Subject Art and are not intended to represent the only configurations in which the Subject Art can be implemented. The detailed descriptions include specific details for the purpose of providing a thorough understanding of the Subject Art. However, it will be apparent to those skilled in the art that the Subject Art can be implemented without these specific details. In some cases, well-known structures and components are shown in the form of block diagrams to avoid obscuring the concepts of the Subject Art. Similar components are labeled with the same element number for ease of understanding. Reference numbers may have letter suffixes to indicate distinct instances of common elements, but are generally referred to by the same number without suffixes.

[0010] The following description is directed towards administering medical fluids by utilizing the disclosed peristaltic pump; however, it should be understood that this description is merely an example of use and does not limit the scope of the claims. Various embodiments of the disclosed peristaltic pump can be used in any application where administering a fluid flow is desirable.

[0011] Figure 1 shows a patient 5 receiving medical fluid infusion using an IV pump 30. In the example shown, the IV pump 30 delivers medical fluid from a fluid container 36 to patient 5. The fluid container 36 is suspended at or above the patient's head and connected to an IV pump module 34 via an IV set 20, and then to patient 5. In some embodiments, the IV pump 30 includes a control unit 32 and a pump module 34. Suitable IV pump configurations and systems are described, for example, in U.S. Patent Application No. 17 / 586,619, the entire disclosure of which is incorporated herein by reference.

[0012] The pump module 34 may include a peristaltic pump for administering medical fluid from the fluid container 36 to the patient 5. It may be desirable to monitor the volume delivered by the peristaltic pump during its operation. In some applications, the peristaltic pump may include antimicrobial functions, as described in more detail below.

[0013] As shown in Figure 1, the IV set 20 includes a fluid container 36, a patient access tip 38, tubing 40, an IV pump 30, and a light source 42 (Figure 2). Note that in the context of this disclosure, the terms “distal” and “proximal” are used relative to the patient 5. The fluid container 36 is capable of containing a medical fluid for intravenous administration (e.g., saline or liquid medication). The fluid container 36 may be rigid, as shown in Figure 1, or it may be a flexible bag containing the medical fluid. The fluid container 36 includes an outlet 44 at its proximal end. The outlet 44 may be a generally circular member extending through the proximal end of the fluid container 36. The outlet 44 may have a diaphragm (not shown) extending across it to prevent the medical fluid from passing through. The outlet 44 may have an inner or outer surface configured to allow other components to be connected, as described in more detail below.

[0014] The tubing 40 may be made of plastic or rubber through which medical fluids can be transported. The tubing 40 may have sufficient rigidity to maintain a generally cylindrical shape when no external force is acting on it. However, the tubing 40 may have sufficient flexibility to bend and change its cross-sectional shape in response to forces acting on it, for example, by a pump as described in more detail below.

[0015] As shown in Figure 2, the tubing 40 may have a distal end 40a and a proximal end 40b. The distal end of the tubing 40 may be configured to connect to an outlet 44. The distal end of the tubing 40 may include a threaded portion or projection which is received in a corresponding threaded portion or recess of the outlet 44. In this way, the outlet 44 and the tubing 40 may be connected by screw coupling, snap fitting, bonding, welding, or any other connection method appropriate for the particular application.

[0016] The proximal end of the tubing 40 can be connected to the distal end of the patient access tip 38. The patient access tip 38 may have an entrance at its distal end. The distal end of the patient access tip 38 may include a threaded portion or projection which is received in the corresponding threaded portion or recess of the tubing 40. In this way, the patient access tip 38 and the tubing 40 can be connected by screw coupling, snap fitting, bonding, welding, or any other connection method appropriate for the particular application.

[0017] The patient access tip 38 has a proximal end configured to be inserted into the patient 5 during the administration of a medical fluid. The proximal end may be a needle sized and shaped to deliver the medical fluid at a desired flow rate. The proximal end may be a 17-gauge needle, 18-gauge needle, 19-gauge needle, 20-gauge needle, 21-gauge needle, 22-gauge needle, 23-gauge needle, 24-gauge needle, 25-gauge needle, 26-gauge needle, 27-gauge needle, 28-gauge needle, 29-gauge needle, or 30-gauge needle. In some embodiments, the fluid container 36 and the patient access tip 38 are in fluid communication through tubing 40.

[0018] The IV pump 30 can be connected to the tubing 40 between the fluid container 36 and the patient access tip 38. As shown in Figure 1, the IV pump 30 can be connected to the tubing 40 closer to the fluid container 36 than to the patient access tip 38. The IV pump 30 may include internal components that engage with the tubing 40 and manipulate its cross-sectional shape so that the flow of the medical fluid can be modulated and controlled according to the specific application of the IV set 20.

[0019] As shown in Figure 2, the light source 42 is capable of emitting light along the tubing 40 toward the patient access tip 38. In some embodiments, the light has antimicrobial properties. For example, the light is capable of killing pathogens. This can reduce bacterial colonization at the patient access site during the administration of medical fluids. The light may be indigo light. Indigo light can have wavelengths from the visible light spectrum at least 405 nm. In some embodiments, indigo light has wavelengths from the visible light spectrum approximately 405 nm, 415 nm, 425 nm, 435 nm, 445 nm, or 450 nm. In some embodiments, indigo light has wavelengths from the visible light spectrum in the range of 405 nm to 425 nm, 410 nm to 420 nm, 405 nm to 450 nm, 415 nm to 440 nm, or 425 nm to 430 nm. In some embodiments, the light source 42 emits light continuously. In some embodiments, the light source 42 emits light intermittently.

[0020] The application of light can reduce bacterial colonization without the need to introduce potentially irritating chemicals or other antimicrobial treatments, and it is possible to avoid using expensive silver or platinum-based materials with natural bactericidal properties. This makes it possible to increase the catheter indwelling time, thereby allowing the IV Set 20 to deliver more medical fluid per use and reducing the number of insertions. Furthermore, unlike other lights commonly used in this field (e.g., ultraviolet-based systems), indigo light is not harmful to the human eye. A description of the use of indigo light as effective against antimicrobial-resistant microorganisms can be found in at least U.S. Patent No. 9,039,966, which is incorporated herein by reference in its entirety.

[0021] Light can be emitted through the tubing 40 by the light source 42. In some embodiments, light is transmitted via an optical fiber filament 46. The optical fiber filament 46 may be located inside the tubing 40, fixed to the inner wall of the tubing 40, embedded in the wall of the tubing 40, fixed to the outer wall of the tubing 40, or any combination thereof. The optical fiber filament 46 may contain a material suitable for transmitting light emitted from the light source 42 (e.g., polystyrene). The optical fiber filament 46 may extend from the IV pump 30 to the patient access tip 38. In some embodiments, the optical fiber filament 46 partially extends from the IV pump 30 to the patient access tip 38. The optical fiber filament 46 may terminate at the most clinically advantageous depth, such as the site most susceptible to infection, or the site where the maximum flexibility of the catheter is balanced with antimicrobial effect.

[0022] As shown in Figure 3, the light source 42 can be located inside the IV pump 30. In some embodiments, light can be transmitted via an optical connector 48. The optical connector 48 is located between the fluid vessel 36 and the patient access tip 38 and can transmit light toward the patient access tip. The optical connector 48 may include a body with an inlet 50 and an outlet 52. The inlet 50 can receive the proximal end of the first segment of the tubing 40, and the outlet 52 can receive the distal end of the second segment of the tubing 40, allowing medical fluid to flow through it. The optical connector can transmit light through the second portion of the tubing 40 in any of the manner discussed above in relation to the optical fiber filament 46 (e.g., inside the inner wall of the tubing 40 or inside the wall). In some embodiments, light can be transmitted via an optical lumen (not shown) extending along the tubing 40. In some embodiments, light can be transmitted through the walls of the tubing 40 (not shown).
