[0004] The present invention relates generally to parenteral acquisition of body fluid samples, and more particularly to the acquisition of body fluid samples present on the skin. A bodily fluid sample having reduced contaminants, such as microorganisms and / or other contaminants external to the source of the bodily fluid. The present invention relates to devices and methods for diversion, isolation, and / or separation of fluids for harvesting.
[0005] Medical practitioners use parenterally obtained body fluids to perform various types of microbial tests on patients. and a wide range of other diagnostic tests are routinely performed. As advanced diagnostic techniques evolve and improve, As a result, the speed, accuracy (both sensitivity and specificity), and value of the information that can be provided to the clinician Also, maintaining the integrity of bodily fluid samples during and / or after collection This also ensures that analytical diagnostic results represent the internal state of the patient. Examples of diagnostic techniques that are not available and / or rely on pure body fluid samples include microbiology. Detection, molecular diagnostics, gene sequencing (e.g., deoxyribonucleic acid (DNA), ribonucleic acid (R These include genomic DNA (GA), next-generation sequencing (NGS), and biomarker identification. may include, but is not limited to, cells that are external to the source from which the sample is obtained. Biological material and / or other extraneous contaminants may be inadvertently included in the body fluid sample to be analyzed. In other words, when samples are taken from a particular body fluid source, inaccurate test results may be derived. The purity of the sample intended to be taken or collected is not compromised during the specimen acquisition process. When such tests are performed, the resulting analytical test results may be inaccurate, abnormal, or defective, false positive, or may be false negatives and / or otherwise not representative of the patient's actual situation, , incomplete, inaccurate, messy, uncertain, unreliable, and / or otherwise undesirable. This could result in better clinical decision-making.
[0006] In some instances, the patient sample (e.g., bodily fluid) may be contaminated with bacteria, fungi, or yeast (e.g., The sample is tested for the presence of one or more potentially undesirable microorganisms, such as Candida albicans. In some instances, microbiological testing may involve the determination of the culture medium, general additives, and / or the presence of microorganisms. One or more sterile and / or non-sterile containers that can accommodate other types of solutions that support growth. In another example, the method may include culturing the patient sample in a bath of bacteria. Samples may be analyzed directly (i.e., not cultured) or the culture medium or In yet another example, various techniques are employed to In the presence of microorganisms and other types of biological material, specific types of cells, biomarkers, and proteins It can aid in the detection of proteins, antigens, enzymes, blood components and / or the like. These include molecular polymerase chain reaction (PCR), magnetic resonance and other magnetic analytical platforms. room, automated microscope, spatial clonal separation, flow cytometry, whole blood ("non-cultured") specimen separation analysis (e.g., NGS) and related techniques, morphokinetic cell analysis, and / or analysis of patient samples. Characterizing and / or detecting specific organisms, antibiotic susceptibility, and / or the like; Used in clinical testing environments to identify, type, classify, and / or characterize These include, but are not limited to, other commonly used or advanced techniques.
[0007] In some instances, detecting the presence of a microorganism may involve determining whether the microorganism and / or organism is present for a period of time (e.g., , which can vary from less than an hour to several hours or days, depending on the diagnostic technique employed. and then allowing the cells to grow (for longer or shorter periods, depending on the circumstances). Automated, continuous monitoring and / or detection and identification of microbial and / or biological growth. and / or in other ways specific to the analytical platform and technology used in the same. Thus, it can be detected.
[0008] In a culture test, for example, if a microorganism is present in a patient sample, the microorganism is cultured in a culture medium. They grow over time in the soil, and in some cases, automated monitoring techniques can detect the growth of the organisms. The presence of microorganisms in the culture medium (observation of carbon dioxide) can be detected. microbial expression (as demonstrated by ELISA and / or other detection methods) in patient samples. This suggests that the same microorganisms are present in the body fluids of the patients from whom the samples were obtained. This suggests the presence of organisms in the culture medium (or, more generally, in the test A patient is diagnosed when the presence of the microorganism is confirmed in the sample used for One specifically designed to treat or otherwise remove unwanted microorganisms from a patient. The above antibiotics or other treatments may be prescribed.
[0009] However, patient samples may be contaminated during acquisition and / or may result in false positives or may be more susceptible to false negative results. For example, the specimen acquisition process (i.e., Needle insertion, peripheral intravenous catheters (PIVs), peripherally inserted central catheters (PICCs), and and / or other indwelling catheter(s) or other lumen-containing device, collection by syringe, or any other suitable means employed to collect patient specimens. Microorganisms on the body surface (e.g., microorganisms present on the skin) that are released into the It then transports the cells directly or indirectly through tissue fragments, hair follicles, sweat glands, and other skin appendage structures. , culture medium, test vial, or other suitable specimen collection vessel or vessel containing a patient sample. It may be included in the sample to be transferred to the transfer chamber and / or analyzed in a non-culture based test. Another possible source of contamination is the people taking the patient samples (doctors, phlebotomists, nurses, technicians, etc.). Specifically, the equipment, materials, and procedures used during the patient sample acquisition process. Products and / or devices often contain multiple components, each of which can introduce potential contamination points. Fluid interfaces (e.g., patient to needle, needle to transfer adapter, transfer adapter to from sample tank, catheter hub to syringe, syringe to transfer adapter, needle / tubing to the sample vessel, and / or any other fluid interface or any combination thereof. In some instances, such contamination may include, but is not limited to, The substance may grow in culture medium and / or be identified by other non-culture based diagnostic techniques. ultimately resulting in false positive and / or false negative microbiological test results. The results of this test may indicate the presence or absence of such microorganisms in the patient (i.e., in the body). may inaccurately reflect the deficiency.
[0010] Such inaccuracies due to contamination and / or other sources of contamination that compromise sample purity. The results may include a broad range of suspected illnesses, diseases, infections, patient conditions, or other conditions of concern. For example, false negative results from microbiological tests are a concern when diagnosing or treating This may result in misdiagnosis and / or delayed treatment of patients' illnesses, and in some cases, Conversely, false positive results in microbiological tests can cause patient death. Patients may need to undergo one or more antimicrobial therapies, which can have serious side effects, including death. This can cause serious side effects, increase the patient's hospital stay and / or other complications related to the incorrect treatment. Complications may result in unnecessary burdens and costs to the health care system. The use of diagnostic imaging equipment due to these false positive results is a problem for various imaging procedures (e.g., CT scanning). The unnecessary exposure to radiation associated with cancer treatment has many negative effects on long-term patient health. It has known adverse effects and is a concern from both a cost and patient safety standpoint.
[0011] In some instances, the devices and / or systems may be used to detect and / or diagnose a sample of bodily fluid for testing. The likelihood of contamination, tampering, and / or the like can be reduced. For example, some Some known devices may harbor contaminants, such as microorganisms present on the skin. Collect, divert, separate, and / or separate the initial volume of bodily fluid, which may be higher. However, some such devices can be configured to The system is often considered cumbersome, difficult to understand, and difficult to use, especially when considering the patient population it targets. In addition, some of these may be unrecognized, inappropriate or unavailable. Devices that are suitable for use with the Internet may require training, user supervision, and / or multiple user intervention. and / or may be influenced by environmental, educational, clinician skills, patient situation, and / or similar factors. These cases present problems where the validity may be otherwise limited based on differences including: In some instances, such issues include uncontaminated, sterile, uncontaminated, etc. This can complicate the collection of reliable, high-quality samples, thereby limiting the quality of test results. This may affect the validity of the argument.
[0012] On the other hand, some known passive shunting devices and / or systems (e.g., direct use Specifically does not utilize or rely on user intervention, interaction, manipulation, and / or the like systems that do not require, for example, the time required to fill an isolation reservoir with a significant volume of fluid. Depending on clinical realities such as time, appropriate division of the clinically desirable and valid pre-test volume of body fluids may be required. In some cases, it may be impossible to flush, isolate, and / or separate the The operation of some known passive devices relies on positive pressure applied by a body fluid source (e.g., the patient's However, positive pressure exerted by a fluid source is not sufficient to The chair is designed to be practical for use in a variety of clinical settings, including emergency rooms and other intensive care settings. For example, the flow velocity and / or force required for the flow to occur is usually insufficient. The symptomatic patient population requiring the above diagnostic tests includes those with hypotensive states (i.e., low blood pressure), Hypovolemic state (i.e., low blood volume) and / or other physical problems (e.g., severe Vascular access problems due to dehydration, obesity, difficult and / or inaccessible vasculature, etc. The physical condition of the subject makes collection of blood and / or body fluid samples difficult to accomplish. Such conditions or physical circumstances may provide sufficient blood flow and / or pressure to allow the isolation chamber, Clinically validated evidence of passive filling of channels, reservoirs, containers (or other divided volumes) and Abnormal, inaccurate, false positive, false negative, and / or otherwise contaminated diagnostic test results Divert, segregate, and / or separate contaminants that may otherwise lead to adverse effects. Problems associated with the technique (e.g., without the use of specific external energy sources and / or negative pressure, Relying on a positive pressure differential applied by a fluid source to achieve an adequate and clinically useful initial volume of fluid collection. The aim of this study is to facilitate the collection of samples from the frail patient population from which these samples are collected. This approach may not be practical since rates may be unacceptably high.
[0013] Therefore, it is important to consider the presence of microorganisms and / or fluid sources on the skin that result in consistent fluid collection. A method for obtaining a body fluid sample with reduced contaminants, such as other contaminants present in the blood, There is a need for a systemic flow diversion device and method (e.g., for treating the general patient population and / or the problem) Some such devices and methods include, for example, It may include fluid collection with the assistance of an energy source and / or negative pressure. Difficulties impacting the ability to demonstrate consistent efficacy and collect bodily fluid samples Issues associated with collecting samples from patients with specific health conditions and / or physical characteristics There needs to be a device that can deal with this.

[0063] As shown in FIGS. 3-5, the housing 230 is adapted to selectively control the flow of bodily fluids through the housing 230. and / or coupled to an actuator 250 configured to selectively control More specifically, the actuator 250 is, for example, a part of the fluid flow path 233 and a fluid The actuator 250 is provided between the actuator 250 and a part of the flow path 254. At a distance from, away from, the junction between the flow path 233 and the isolation chamber 234, and / or Although shown positioned downstream, in other embodiments, the actuator 250 , may be provided in any suitable location within the housing 230. For example, in some embodiments In the embodiment, the actuator 250 includes a fluid flow path 233, a separation chamber 234, and a fluid flow path 2 54. Cut.
[0064] The actuator 250 may be of any suitable shape, size, and / or configuration. For example, in some embodiments, the actuator 250 may be configured to have a first state and a second state. The present invention may be any suitable member or device configured to transition between the above-mentioned components. In this embodiment, when the actuator 250 is in the first state, it is in communication with the fluid flow path 233. Separate, isolate, separate, and / or otherwise provide fluid communication between the body flow passage 254 and the When in the second state, the fluid passage 233 is configured to block the fluid passage 254.

One or more seals 265 configured to selectively allow fluid communication between the It can include.
[0065] Actuator 250 is specifically shown in FIGS. 2-5 and described above, but in other embodiments The control device 200 selectively enables fluid communication between the fluid flow paths 233 and 254. The actuator may include any suitable actuator or device configured to: Therefore, although specifically illustrated in FIGS. 2 to 5, the control device 200 is not limited to the above. It should be understood that this is presented as an example. For example, actuator 250 is shown in FIG. Although the actuators are shown in a given position in FIG. The actuator 250 may be located at any suitable location along the housing 230. For example, In some embodiments, the actuator 250 includes a fluid flow path 233 and an isolation chamber. 234 and the inlet 231. In such an embodiment, the actuator When the actuator 250 is in a first state, the flow of bodily fluid is from the inlet 231 to the isolation chamber 2 34 when the actuator 250 is in the second state. 231 directly into the fluid flow path 254. In other words, the actuator 2 When the actuator 250 is in the first state, the actuator 250 causes bodily fluid to flow from the inlet to the isolation chamber 2. A portion of the isolation chamber 234 may be formed to flow directly into the access 34. When activating, positioning, and / or transitioning the actuator 250 to the second state, e.g. For example, actuator 250 may be configured to allow bodily fluid to flow directly from inlet 231 to fluid flow path 233. In such an embodiment, the actuator 250 may 31, the isolation chamber 234, and the fluid flow path 233. Furthermore, when in the second state, the actuator 250 can move the isolation chamber 234 Operable to at least partially isolate the inlet 231 and / or the fluid flow path 233. could be.
[0066] Further, the actuator 250 may be actuated and / or transitioned in any suitable manner. For example, in some embodiments, the actuator 250 may be manually actuated by a user ( For example, applying manual force to a button, slider, switch, rotating member, etc. The actuator 2 can transition between the first and second states. 50, pressure difference (or lack thereof), change in potential or kinetic energy, composition or The actuator may undergo a change in configuration (e.g., a portion of the actuator at least partially decomposes or changes shape). automatically transitioning between the first and second states in response to a In yet another embodiment, the actuator 250 may be configured to mechanically and / or electrically actuated or transitioned based on time, volumetric flow rate, flow rate, etc. Examples of actuators and / or ways in which actuators can transition are provided herein. Although provided in the specification, they are presented only as examples and not as limitations. It should be understood that the control device 200 may therefore be adapted to transition in any suitable manner. The actuator may include any suitable actuator configured.
[0067] As described above, the device 200 can be used to detect, for example, microorganisms present on the skin and / or similar. It is possible to obtain a body fluid sample having reduced contamination from microorganisms such as those of For example, in some instances, users such as doctors, physicians, nurses, phlebotomists, and technicians may The chair 200 may be operated to provide fluid communication between the inlet 231 and a source of bodily fluid (e.g., a patient's blood vessel). The inlet 231 is in fluid communication with a source of bodily fluid (e.g., a portion of a patient). When positioned in the fluid collection device, the outlet 236 may be fluidly coupled to a fluid collection device. As such, in the embodiment shown in Figures 2-5, the fluid collection device may be, for example, a vacuum that defines a negative pressure. It may be a reservoir or container and / or any other suitable source of negative pressure.
[0068] By coupling the outlet 236 to a fluid collection device, at least one of the fluid flow paths 254 A portion is selectively exposed to negative pressure within the fluid collection device. The controller 242 is in fluid communication with the fluid flow passage 254 and the isolation chamber 234. Thus, by coupling the outlet 236 to a fluid collection device, the isolation chamber becomes a fluid collection The device is exposed to negative pressure, which draws bodily fluid from a bodily fluid source (e.g., a patient) through inlet 2. 31 and into the housing 230. As described above with reference to the control device 100, the housing 230 is adapted to accommodate a volume of bodily fluid. When transferred to and / or through port 231, an initial portion of the volume of bodily fluid (referred to herein as The initial volume (also called the “initial volume” or “first volume”) is a volume that flows from the inlet 231 through the fluid flow path 233. , through at least a portion of the separation chamber 234. That is, in some embodiments, the control device 200 and / or the housing 230 , an initial portion or volume of bodily fluid is introduced into or through at least a portion of the fluid flow path 233; and may be in a first or initial state in which it is capable of flowing into the segregation chamber 234.
[0069] As described above, the flow controller 242 and the actuator 250 are in a first state, position When in position, configuration, etc., the housing 230 and / or the control device 200 are in an initial state. Therefore, the actuator 250 is directly connected between the fluid flow paths 233 and 254. Separate, separate, separate, isolate, and / or otherwise prevent the flow of fluid therethrough. Additionally, the inlet 231 is exposed to a negative pressure differential via the isolation chamber 234. The negative pressure in the fluid collection device may be increased by the housing 230 and / or the control device 200 being first or initial state, an initial flow of body fluid is directed from the inlet 233 to the isolation chamber 234. A negative pressure (or negative pressure) is provided within at least a portion of the isolation chamber 234 that is operable to draw in It is possible to generate a pressure difference.
[0070] When the flow controller 242 is in a first or initial state, the housing 130 As described above with reference to a fluid collection device (e.g., a sample reservoir, a syringe, or Depending on the negative pressure of the flow control (other potential energy sources used to generate negative pressure), The roller 242 may allow the flow of a fluid (e.g., gas or air) therethrough. In some instances, it may be desirable to regulate and / or control the magnitude of the negative pressure differential. In the embodiment shown in FIGS. 2 to 5, for example, the housing 230 may include a flow control The flow control unit 242 defines a fluid flow passage 254 and a restricting flow passage 232 through which a fluid can flow. More specifically, the restricted flow passage 232 has a diameter smaller than at least the fluid flow passage 254. A fluid flow path having a
[0071] For example, in some embodiments, the restricted flow passage 232 may be approximately 0.0005 inches, approximately 0. 001 inch, approx. 0.003 inch, approx. 0.005 inch, approx. 0.01 inch, approx. 0.1 In other embodiments, the restricted flow path may have a diameter of about 0.5 inches or greater. 232 may have a diameter less than 0.0005 inches or greater than 0.5 inches. In some embodiments, the restricted flow passage 232 is about 0.01 inches, about 0.05 inches, about 0.06 inches, about 0.08 inches, about 0.09 inches, about 1.0 ... 0.1 inch, about 0.15 inch, about 0.2 inch, about 0.5 inch or more of a given and / or can have any desired length. In other embodiments, the restriction channel 232 is 0.01 may have a predetermined and / or desired length of less than about 0.5 inches or more than about 0.5 inches. Further, in some embodiments, the restricted flow path 232 is at least one of the control device 200. The diameter and length to allow and / or provide desirable flow characteristics through the portion. The thickness may have any suitable combination of thicknesses.
[0072] In this embodiment, when the restrictive flow passage has a larger diameter, the The restriction flow path 232 is configured to reduce the amount of negative pressure applied through the isolation chamber by more than the amount of negative pressure. In some cases, the amount of negative pressure can be adjusted to reduce fluid sequestration. The rate at which the material is transferred into the chamber 234 can be controlled. For example, in some implementations In one embodiment, the fluid collection device and / or other suitable negative pressure source provides approximately 0.5 pounds per square inch. PSI, approx. 1.0 PSI, approx. 2.0 PSI, approx. 3.0 PSI, approx. 4.0 PSI, approx. 5.0 PSI, about 10 PSI, about 12.5 PSI, or about 14.7 PSI (e.g., approximately at or substantially near atmospheric pressure at sea level (e.g., negative magnitude) In some embodiments, a fluid collection device, such as a vacuum vessel, may be used to generate a negative pressure differential. The gas may have a predetermined negative pressure of about 12.0 PSI. By controlling the diameter and / or length of the separator 232, the amount of negative pressure to which the separator chamber 234 is exposed can be controlled. The amount and / or rate at which negative pressure is applied may be controlled, reduced, and / or otherwise adjusted. In some examples, the restriction flow path 232 may be used to increase the flow rate of the separation chamber. There may be a delay or build-up of negative pressure applied to or within the isolation chamber.
[0073] Further, in this embodiment, the restricted flow path 232 may be configured to restrict the flow of liquid (e.g., bodily fluids), for example. Rather, it is a gas flow path configured to receive a flow of gas or air. In this embodiment, the diameter of the restriction passage 232 limits the flow of liquid therethrough and / or In addition, the fluid flow path 254 and the flow controller 242 may be small enough to obstruct the The restricted flow path 232 between the is substantially blocked by a trap 242 (e.g., a selectively permeable barrier or seal) They are arranged as follows.
[0074] The pressure regulation is based on the diameter of the restricted flow passage 232 (i.e., the single restricted flow passage). Although the above has been described, it should be understood that this is presented by way of example only, and not limitation. Other means for adjusting the amount of negative pressure to which the isolation chamber is exposed include, for example, a porous A porous material, a valve, a membrane, a diaphragm, a specific restriction, a vent, a deformable member or a flow passage and / or In other embodiments, the control device may include any suitable number of each restriction flow passage may have substantially the same diameter. For example, in some embodiments, the control device may include up to 100 or more restriction channels. In such an embodiment, each restriction The flow passage may be from about 0.0005 inches to about 0.1 inches, from about 0.0005 inches to about 0.05 inches. The diameter may be about 0.0005 inches to about 0.01 inches. In some embodiments, the multiple restricted flow paths may be configured to include: (1) an outlet that exposes the isolation chamber 234 to a negative pressure differential; (2) selectively providing a flow path between the port 236 and the isolation chamber 234; and The membrane is configured to selectively permit the passage of air while substantially preventing the passage of liquids (e.g., bodily fluids). The flow controller may be configured to act as a flow controller configured to
[0075] In some embodiments, the isolation chamber 234 can be configured to adjust the amount of pressure to which it is exposed. and / or control the amount of pressure exerted on the patient's bodily fluids and / or blood vessels. In some instances, such pressure regulation can be achieved, for example, by adjusting the pressure of a blood sample. This can reduce the likelihood of hemolysis and / or vascular collapse. The ability to regulate and / or control the amount or magnitude of pressure allows the patient to overcome physiological difficulties. so that sudden forces can be applied to facilitate collection of bodily fluids, e.g. blood. Not flattened, collapsed, invaginated, and / or otherwise impaired in its patency and blood collection ability Negative pressure is required (the pressure difference between atmospheric pressure and the patient's vascular pressure) to promote uniform and sufficiently strong flow. The device 200 can be used for a wide range of patients, many of whom do not have sufficient It is Noh.
[0076] As described in detail above with reference to the control device 100, the initial portion of the body fluid and / or The initial volume can be any suitable volume of bodily fluid. For example, in some instances, the initial volume is: The amount or volume of body fluid sufficient to completely wet or saturate the flow controller 242 In other words, several In some embodiments, the initial volume of bodily fluid may be adjusted to place the flow controller 242 in a second state (e.g., In some implementations, the volume may be sufficient to transition the liquid to a saturated or fully wetted state. In one embodiment, the flow controller 242 is placed in a sealing configuration when transitioned to the second state. That is, the flow controller 242 (e.g., a semi-permeable material) is saturated and / or or completely wetted, the flow controller 242 is 2 are disposed in a sealing configuration that substantially prevents the flow of liquids and gases therethrough. By transitioning the flow controller 242 to the second state, the flow is isolated from the restricted flow path 232. Flow through the flow controller 242 to or from the chamber 234 is isolated or blocked. Separated, separated, set apart, spaced apart, and / or otherwise obstructed.
[0077] After the initial volume of bodily fluid has been transferred and / or diverted into the isolation chamber 234, the control device The chair 200 and / or housing 230 are transitioned to its second state or mode of operation. To isolate, separate, hold, contain, or separate the initial volume within isolation chamber 234. For example, as described above, the flow controller 242 may be placed in a sealed configuration. In addition, the actuator 250 transitions from its first state to its second state. 254. Therefore, negative pressure applied otherwise on or through the isolation chamber 234 Here, on or through the fluid flow paths 233 and 254, In response, bodily fluid flows from inlet 231 through fluid flow paths 233 and 254 to outlet 236. 36 and into the fluid collection device. The flow controller 242 and the actuator 250 are respectively moved from the first state to the second state. Each of the transitions to the second state causes an initial portion of the bodily fluid in the isolation chamber 234 to be isolated. As described in more detail herein, In some cases, such as microorganisms present on the skin that are expelled during venipuncture, Contaminants may be entrained and / or contained in the initial volume of body fluid and thus When the initial volume is isolated therein, it is isolated within the isolation chamber 234 .
[0078] A fluid collection device is fluidly coupled to the outlet 236 and is connected to the control device 200 and / or the handheld device 202. When the housing 230 is in a second state (e.g., an initial volume of bodily fluid is in or around the isolation chamber 234), 2, any subsequent volume(s) of body fluid is / are introduced into the inlet 2 31, through fluid flow paths 233 and 254, through outlet 236, and into the fluid collection device. Thus, as described above, a test volume of one or more body fluids can be By isolating an initial volume of bodily fluid in the isolation chamber 234 prior to collection or acquisition. This reduces and / or substantially eliminates the amount of contaminants in one or more test volumes. Further, in some embodiments, the control device 200 and / or the housing 230 may be The control device 200 and / or the housing 230 may contain an initial volume within the isolation chamber 234. Before consolidating and isolating, the devices may be arranged so that they cannot transition to the second state. .
[0079] The control device 200 may be configured to switch between a first state and a second state (e.g., by a user). The actuator 250 is configured to move the actuator 250 (through a force applied to the actuator 250). 2-5, in other embodiments, the control device may include two or more Any suitable member or device configured to selectively establish fluid communication between fluid flow paths. For example, Figures 6-8 show a fluid control device according to one embodiment. The fluid control device 300 is similar to the fluid control device described above with reference to FIG. The device 100 and / or the fluid control device 200 described above with reference to FIGS. The fluid control device 100 and the fluid control device 110 may be similar in form and / or function. and / or a portion of 200. The specification does not go into further detail.
[0080] As shown in FIGS. 6 to 8, a fluid control device 300 (referred to herein as a “control device”) or "device") has an inlet 331 and an outlet 336, and an actuator The control device includes a housing 330 that includes an actuator 350 or is coupled to an actuator 350.

[0097] When in the first state, the first plunger 460 causes the damping chamber 437 to become the isolation chamber. A spring 434 is formed on the side of the first plunger 460 opposite the spring 434 by the housing 430.

The damping fluid 456 in the chamber 437 damps the negative pressure applied to the first plunger 460. Therefore, the actuator 450 and / or the control device 400 are You can control the rate at which the transition from state 1 to state 2 occurs. By subjecting the housing 430 to maximum negative pressure, the amount of bodily fluid in the isolation chamber 434 is reduced.

The container or device may be any other suitable container or device configured to generate or produce a
[0138] For example, outlet 853 may be configured to accommodate a fluid collection system, as described in detail above with reference to device 200. By coupling to the device 880, at least a portion of the control device 800 Selectively exposed to negative pressure within and / or generated by the body collection device 880 More specifically, in the embodiment shown in Figures 19 to 25, the outlet 853 is connected to the fluid collection device 8 80, the outlet 853 of the actuator 850 and the second fluid flow path 85 4 is exposed to negative pressure within and / or generated by the fluid collection device 880 In addition, the second port 859 of the actuator 850 is connected to the second fluid flow path 854 and the The housing 830 is in fluid communication with a second port 846. A second port 846 of 830 is connected to the flow controller 842 and the restricted flow path 832. The device 800 and / or the isolation chamber 834 may be selectively in fluid communication with each other. The flow controller 842 is while allowing the flow of gas (e.g., air) through the flow controller 842. a first operating state that restricts and / or prevents the flow of a liquid (e.g., a bodily fluid such as blood); or In the first mode, the fluid collection device 880 is coupled to the outlet 853. This allows the fluid collection device 880 (and / or any suitable negative pressure source) and the isolation chamber A negative pressure difference is generated between the heater 834 and the heater 834.
[0139] As described above, the flow controller 842 and / or the actuator 850 are in a first state. When the control device 800 is in a state, position, configuration, etc., the control device 800 is in a first or initial state. Therefore, the actuator rod 862 is connected to the first fluid passage 833 through the inlet 852. It may be in its first position and / or configuration that allows fluid to flow therethrough. The first port 858 of the actuator 850 and the first port 845 of the housing 830 are spaced apart. This allows fluid communication between the separation chamber 834 and the first fluid flow path 833. , when the actuator 850 and / or the control device 800 are in a first or initial state. (e.g., actuator rod 862 is in its first state, position, and / or configuration) When the fluid is collected, the negative pressure in the fluid collection device 880 reduces the initial flow, portion, amount, or volume of the bodily fluid. From the inlet 852, through the first fluid flow path 833 and into the isolation chamber 834. Creating a negative pressure (or negative pressure differential) within at least a portion of the isolation chamber 834 that is operable to In some examples, the device 200 may be configured as described in detail above. In this manner, the flow controller 842 and / or the restriction flow path 832 may be disposed in the isolation chamber 83. Limit or restrict the amount or magnitude of negative pressure applied onto or through isolation chamber 834. , control, and / or otherwise regulate.
[0140] As described above in detail with reference to the control device 100, the initial portion and / or the initial portion of the bodily fluid The amount can be any suitable amount of bodily fluid. For example, in some instances, the initial volume is - an amount or volume of bodily fluid that is sufficient to completely wet or saturate the controller 842 It may be related to and / or based at least in part on. In other words, some In an embodiment, the initial volume of bodily fluid is determined by switching the flow controller 842 from the first state to the second state. The volume may be sufficient to transition the liquid to a saturated or fully wetted state. In some embodiments, the flow controller 842, when transitioning to the second state, That is, the flow controller 842 (e.g., a semi-permeable material) is positioned By becoming saturated and / or completely wetted, the flow controller 842 The controller 842 is positioned in a sealing configuration that substantially prevents the flow of liquids and gases therethrough. Therefore, by transitioning the flow controller 842 to the second state, The flow through the flow controller 842 between the restriction flow path 832 and the isolation chamber 834 is To be isolated, blocked, separated, set apart, set apart, and / or otherwise hindered It will be stopped.
[0141] After the initial volume of bodily fluid has been transferred and / or diverted to the isolation chamber 834, the control device 800 and / or actuator 850 are transitioned to their second state or mode of operation. , to isolate, separate, hold, contain, or separate the initial volume within the isolation chamber 834. For example, the actuator 850 may be, for example, an actuator rod. 862 from its first state to its second state by applying a force to the second end 864 of the Thus, the actuator rod 862 can be actuated to transition to the first flow. a second state, position, and / or location of the body passageway 833 isolated and / or separated from the inlet 852; and / or moved and / or transferred to the configuration. The flow controller 842 is in a sealing configuration in response to an initial volume of bodily fluid, and the inlet 852. An initial volume of bodily fluid may be obtained by an initial fluid flow path 833 that is isolated and / or separated from the is isolated within the isolation chamber 834. As described in detail above, in some instances, e.g. For example, contaminants such as microorganisms present on the skin that are expelled during venipuncture may increase the initial volume of fluid. may be mixed and / or contained within the initial volume and thus become sequestered therein. 834.
[0142] As shown in FIG. 24, the control device 800 and / or the actuator 850 may be 8. The second fluid flow path 854 is then moved and / or transitioned to a state or configuration of Thus, fluid communication is established between the inlet 852 and the outlet 853. Negative pressure applied on 34 or otherwise through isolation chamber 834 now acts on fluid flow path 854. In response, bodily fluid is directed from inlet 852 to fluid flow path 854. , through outlet 853 and into fluid collection device 880. Thus, as described above, prior to collection or acquisition of one or more test volumes of bodily fluid, a separation By isolating an initial volume of bodily fluid in the isolation chamber 834, one or more test volumes The amount of contaminants is reduced and / or substantially eliminated. The control device 800 is configured to adjust the initial volume in the isolation chamber 834. Before consolidation and isolation, the second state can be arranged so that it cannot be transitioned to the second state. , thereby reducing the likelihood of contaminants being transferred to the fluid collection device 880.
[0143] In some instances, for example, multiple fluid collection devices 880 (e.g., syringes) may be used. When it is desirable to collect multiple samples of a body fluid using a negative pressure source (e.g., It may be desirable to separate the collection device 880 from the inlet 853. For example, some In some examples, after filling the fluid collection device 880, the user may press the actuator 850 862 to apply a force to the first end 863 of the actuator rod 862 to activate the actuator The rod 862 is moved from its second position and / or configuration to its first position and / or configuration. Therefore, the second fluid flow path 854 can move and / or transition along the inlet The port 852 is not arranged to be in fluid communication with the outlet 853. The rollers 842 are arranged such that the outlet 853 is substantially isolated or spaced from the remainder of the control device 800. A sealed state or configuration (e.g., completely saturated) so as to be separated or isolated. , wetted, and / or otherwise impede flow therethrough). In this example, the user then inserts the filled fluid collection device 880 (e.g., a syringe) and connect a new fluid collection device 880 (e.g., a syringe) to the outlet 853. As described above, a novel fluid collection device 880 coupled to the outlet 853 may be used. This allows a user to, for example, apply force to the second end 864 of the actuator rod 862. , moving the actuator rod 862 back to the second position, state, and / or configuration. and / or transitions.

A reduced bodily fluid sample can be obtained. For example, the actuator rod 1362 is moved relative to the body 1351 between a first position or configuration and a second position or configuration. As shown in FIG. 13, the inlet 1352 of the actuator 1350 is in fluid communication with the first fluid flow path 1333. 13B, whereby the first fluid flow passage 1333 is in fluid communication with the first port 1358. The outlet 1353 of the actuator 1350 is connected to a second fluid flow path 1354 and a fluid flow path. The second fluid flow path 1354 is in fluid communication with the second port 1359. Therefore, the actuator 1350 and / or the actuator rod 13 62 is in a first position and / or configuration (e.g., when the control device 1300 is in a first state When in a fluid collection mode, negative pressure in the fluid collection device (not shown in FIGS. 35-40) The first flow, amount, or volume of the bodily fluid is at least partially guided from the inlet 1352 to the first flow.

As described in detail above, In some instances, for example, during venipuncture or throughout the fluid collection process, Contaminants, such as microorganisms present on the exposed skin, may be introduced and / or entrained in the initial volume of body fluid. Thus, when the initial volume is isolated therein, Therefore, the separation chamber 1334 is isolated from the surroundings. The negative pressure applied otherwise is now on or through the second fluid flow path 1354. In response, bodily fluid flows from the inlet 1352 through the second fluid flow path 1354. 1353, through the outlet 1353 and into the fluid collection device 1353.

In this embodiment, the initial volume of bodily fluid is controlled by a flow controller 1642 (e.g., a selective permeation In response to negative pressure applied through the barrier membrane, the fluid may be drawn into the isolation chamber 1634. In some examples, at least a portion of the bodily fluid drawn into the isolation chamber 1634 may be The flow controller 1642 can then be contacted by the flow controller 16 42 can transition from a first state to a second state (e.g., a flow controller 1642 restricts and / or substantially prevents the flow of gases and liquids therethrough. Thus, a negative pressure can be generated on the surface of the diaphragm 1676, causing the diaphragm to be in a first state. and / or configuration to a second state and / or configuration, (See FIG. 52.)

Some such implementations can be configured to transition in response to exposure to In an embodiment, the diaphragm 1676 (and / or at least a portion thereof) is subjected to a predetermined negative pressure difference or a predictable and / or predetermined manner from a first state to a second state after being subjected to a constant rate of negative pressure change 2, so that it acts in the same way as the flow controller 1642. Additionally, the transition of the diaphragm 1676 can be automatic (e.g., (not due to user intervention).

In other words, the first state The transition from the first state to the second state occurs in some cases when the last part of the initial volume of fluid enters the sequestration chamber. When the housing is being transferred into the chamber, the housing begins to transition from the first state to the second state. In some examples, the transition from the first state to the second state may be relatively gradual. Selectively control the rate of change when a transition occurs to achieve one or more desirable properties associated with the transition. Furthermore, in some such instances, the flow of the final portion of the initial volume may be and / or The transition from the first state to the second state can thus be prevented or substantially prevented. This may occur over a given period of time, but the isolation chamber may still have a A volume of fluid can be sequestered.
