[0004] In a particular embodiment, a method is disclosed comprising introducing a flow into a chamber having a chamber interior; directing the flow into the chamber interior at a first flow rate via a priming port; moving a disc valve to direct the flow from the priming port to a drip port; and directing the flow into the chamber interior at a second flow rate via the drip port, wherein the second flow rate is less than the first flow rate.
[0005] In a particular embodiment, an IV set is disclosed, comprising a fluid supply source and an IV set component having a chamber body defining a chamber interior and an outlet, with the chamber interior in fluid communication with the outlet; an inlet portion coupled to the chamber body defining an inlet, a priming port, and a drip port, with the inlet in fluid communication with the priming port and the drip port, the priming port and the drip port respectively in fluid communication with the chamber interior, and the inlet in fluid communication with the fluid supply source; and an IV set component having a disc valve coupled to the inlet portion that can be moved to direct flow from a first portion of the tubing to the priming port in a first position and to direct flow from the first portion of the tubing to the drip port in a second position.
[0006] Various configurations of the Art will be readily apparent to those skilled in the art from this disclosure, and it will be understood that various configurations of the Art are shown and described as examples. As will be recognized, other different configurations of the Art are possible, and some of its details can be modified in various other ways, all without departing from the scope of the Art. Accordingly, the summary, drawings, and detailed description are to be considered illustrative in nature and not limiting.
[0007] The accompanying drawings are included for further understanding and are incorporated into this specification and constitute part thereof, but serve to illustrate the disclosed embodiments and, together with their description, to illustrate the principles of the disclosed embodiments. [Brief explanation of the drawing]
[0008] [Figure 1] This is a diagram depicting a patient receiving medical fluid infusion using an IV pump. [Figure 2] This is a cross-sectional view of a drip chamber assembly according to a particular aspect of the present disclosure. [Figure 3] Figure 2 is a top view of the disc valve of the drip chamber assembly. [Figure 4A] Figure 2 is a cross-sectional view of the drip chamber assembly in a drip configuration. [Figure 4B] Figure 2 is a cross-sectional view of the drip chamber assembly in the priming configuration. [Modes for carrying out the invention]
[0009] The disclosed IV set components provide a priming channel, a drip channel, and a valve for directing the flow between the priming channel and the drip channel. The IV set components selectively enable rapid priming and drip flow into the chamber.
[0010] The detailed descriptions below are intended to describe various configurations of the Art and not to present a limited number of configurations in which the Art can be implemented. The detailed descriptions include specific details for the purpose of providing a thorough understanding of the Art. However, it will be apparent to those skilled in the art that the Art can be implemented without these specific details. In some examples, well-known structures and components are shown in block diagrams to avoid obscuring the concepts of the Art. Similar components are represented by the same element number for ease of understanding. Reference numerals are used generically by the same number without subscripts, although subscripts may be used to indicate distinct examples of common elements.
[0011] The following description pertains to drip chambers for administering medical fluids using the disclosed drip chambers, but 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 drip chambers may be used in any application where rapid priming is desirable, such as drip chambers, in-line drip chambers, dual-input drip chambers, burettes, or other IV set components.
[0012] The disclosed drip chamber overcomes several difficulties found with certain conventional drip chambers. One difficulty with certain conventional drip chambers is that they may require a significant amount of time to aspirate sufficient medical fluid for priming. Another difficulty with certain conventional drip chambers is that they require repeated manual work to aspirate sufficient medical fluid for priming. The use of conventional drip chambers is undesirable because the significant priming time can delay the procedure, draw the clinician's attention, and the repeated manual work can exhaust the clinician.
[0013] Therefore, it is advantageous to provide a drip chamber described herein that enables rapid priming without requiring manual work. The disclosed drip chamber provides a priming channel, a drip channel, and a valve for directing the flow between the priming channel and the drip channel to enable rapid priming and drip flow as desired.
[0014] An example of a drip chamber that enables rapid priming and control of the drip flow is described here.
[0015] Figure 1 illustrates a patient 5 receiving medical fluid infusion through an IV pump 30 according to a particular embodiment of the present disclosure. The IV pump 30 has a controller 32 and two pump modules 34. An IV set 20 is connected between a container 36 of medical fluid and the patient 5. Before use, the components of the IV set 20 may be primed with medical fluid. Drip chamber assemblies described herein may enable the priming process and delivery of medical fluid to the patient 5. In some embodiments, the drip chamber assembly may be positioned between or in line with the tubing of the IV set 20. As can be recognized, the drip chamber assembly may be used in other applications without the IV pump 30. For example, the drip chamber assembly may be coupled to a fluid supply source such as a fluid bag.
[0016] Figure 2 illustrates a cross-sectional view of a drip chamber 100 according to a particular aspect of the present disclosure. Referring to Figure 2, the drip chamber 100 provides a visual indicator of the flow rate of the medical fluid passing through it. Advantageously, a clinician can monitor and adjust the flow rate of the medical fluid based on the visual indicator provided by the drip chamber 100.
[0017] During use, the medical fluid can drip or flow through the chamber chamber 152 defined by the chamber body 150. The medical fluid can enter the chamber body 150 through an upper or inlet 110 coupled to the chamber body 150. The inlet 110 may be in fluid communication with the chamber body 150, allowing the medical fluid to flow from the inlet 110 into the chamber chamber 152. The medical fluid can exit the chamber body 150 through a lower or outlet 154. The outlet 154 may be in fluid communication with the chamber chamber 152. The inlet 110 and / or outlet 154 may be coupled to the tubing of the IV set 20.
[0018] In the illustrated examples, the inlet 110 may define an inlet channel 114 to allow medical fluid to enter the chamber body 150. Optionally, the inlet 110 may include or define a spike 112 for penetrating a diaphragm, such as the diaphragm of an IV vessel. In some embodiments, the inlet channel 114 may be formed through a spike 112 extending from the inlet 110.
[0019] As the fluid passes through the chamber body 150, the clinician can utilize the drip chamber 100 as a visual indicator to observe the dripping or flow of the medical fluid passing through it. The chamber body 150 may be transparent or translucent so as to allow the clinician to visually observe the dripping or flow of the medical fluid within the chamber chamber 152.
[0020] In the illustrated example, the drip chamber 100 may allow a medical fluid to drip within the chamber body 150 at a controlled drip rate. While in use, the medical fluid can flow from the inlet channel 114 to a drip port 142 formed in the inlet 110. The drip port 142 may be dimensionally defined, shaped, or otherwise configured to produce a desired drip or flow rate into the chamber body 150. In some embodiments, the drip port 142 may be coupled to a drop former 143 to allow droplets to be easily formed within the drip chamber 100. As can be recognized, the flow rate of the medical fluid through the drip port 142 may be configured to supply a suitable medical fluid for the desired operation (e.g., 20 drops per minute).
[0021] In some embodiments, a medical fluid can flow from the inlet channel 114 to the drip port 142 via a manifold 130 formed within the inlet 110. As illustrated, the manifold 130 may include or define a drip channel 132 for directing the flow from the inlet channel 114 to the drip port 142.
[0022] Furthermore, in the illustrated example, the drip chamber 100 can aspirate medical fluid for priming the IV system. As can be appreciated, the chamber inner chamber 152 can be filled with a desired amount of medical fluid during the priming operation. In some embodiments, the chamber inner chamber 152 can be filled from approximately half to two-thirds of the total volume of the chamber inner chamber 152.
[0023] During priming, the drip chamber 100 can allow medical fluid to flow into the chamber body 150 at an accelerated or greater flow rate compared to the flow rate of the drip port 142. In the illustrated example, the medical fluid can flow from the inlet channel 114 to the priming port 144 formed in the inlet portion 110. The priming port 144 can be sized, shaped, or otherwise configured to provide a desired flow rate into the chamber body 150. In some embodiments, the priming port 144 can include an enlarged outlet portion 145.
[0024] In some embodiments, the medical fluid can flow from the inlet channel 114 to the priming port 144 through a priming flow path 134 defined within the manifold 130. The priming flow path 134 can direct the flow from the inlet channel 114 to the priming port 144.
[0025] In some embodiments, the drip chamber 100 can include a vent port 146 for equalizing the differential pressure between the chamber inner chamber 152 and the surroundings during the priming operation. The vent port 146 can provide fluid communication between the priming port 144, the chamber inner chamber 152, and / or the surroundings to equalize the differential pressure. Advantageously, by allowing the pressure within the chamber inner chamber 152 to equalize with the surroundings during priming, the flow rate through the priming port 144 can be increased relative to the flow rate through the drip port 142.
[0026] The vent port 146 can communicate fluidly with the priming channel 134 of the manifold 130. The vent port 146 can balance the differential pressure between the surroundings and the priming channel 134 during the priming process.
[0027] In the illustrated example, the drip chamber 100 may be configured to allow increased drip flow during normal operation and increased priming flow during priming operation. Figure 3 illustrates a top view of the disc valve 120 of the drip chamber 100 in Figure 2. Referring to Figures 2 and 3, the disc valve 120 can direct flow from the inlet channel 114 to the drip port 142 for drip operation or to the priming port 144 for priming operation.
[0028] While in use, the disc valve 120 can be moved to direct the flow from the inlet channel 114 toward the drip port 142 or the priming port 144. As illustrated, the disc valve 120 defines a flow section 124 through which the flow passes. The flow section 124 may be shaped or otherwise configured to direct the flow from the inlet channel 114 toward the drip port 142 and / or the priming port 144. The disc valve 120 further defines a sealing section 122, which is shaped to block or stop the flow from the inlet channel 114 toward the drip port 142 and / or the priming port 144.
[0029] In the illustrated example, the flow portion 124 and sealing portion 122 of the disc valve 120 may be moved or aligned to control the flow from the inlet channel 114 and the operation of the drip chamber 100. The disc valve 120 may be slid, moved, rotated, or otherwise actuated to adjust the position of the disc valve 120.
[0030] Figure 4A illustrates a cross-sectional view of the drip chamber 100 of Figure 2 in a drip configuration. Referring to Figures 2 to 4A, the disc valve 120 can be moved to enable the drip chamber 100 to operate in a drip configuration. In the illustrated example, the disc valve 120 can be moved to align the flow section 124 to direct the flow from the inlet channel 114 toward the drip port 142. As illustrated, the flow section 124 can direct the flow from the inlet channel 114 through the drip passage 132 toward the drip port 142, allowing the drip flow F to accumulate in the chamber 152. Furthermore, the sealing section 122 can be aligned to block the flow from the inlet channel 114 toward the priming port 144. As illustrated, the sealing section 122 can seal the priming passage 134, preventing the flow from the inlet channel 114 from entering the priming port 144.
[0031] Figure 4B illustrates a cross-sectional view of the drip chamber 100 of Figure 2 in a priming configuration. Referring to Figures 2, 3, and 4B, the disc valve 120 can be moved to enable the drip chamber 100 to operate in a priming configuration. In the illustrated example, the disc valve 120 can be moved to align the flow section 124 to direct the flow from the inlet channel 114 toward the priming port 144. As illustrated, the flow section 124 can direct the flow from the inlet channel 114 through the priming passage 134 toward the priming port 144, allowing the priming flow P to accumulate in the chamber 152. Furthermore, the sealing section 122 can be aligned to block the flow from the inlet channel 114 toward the drip port 142. As illustrated, the sealing section 122 can seal the drip passage 132, preventing the flow from the inlet channel 114 from entering the drip port 142.
[0032] As described herein, the disc valve 120 may be moved to change the drip chamber 100 between a drip configuration and a priming configuration. The disc valve 120 may be slid, moved, rotated, or otherwise actuated to adjust the position of the disc valve 120. In some embodiments, the disc valve 120 is rotatable relative to the inlet 110. Optionally, the outer portion 126 of the disc valve 120 may be rotated to move or otherwise actuate the disc valve 120 and adjust the position of the flow portion 124 and / or sealing portion 122 of the disc valve 120.
