Abstract
Description
Technical Field
[0001] The present invention relates to a blood collection system, a protective needle housing system, and a method of collecting blood from a patient via the blood collection system.
Background Art
[0002] Catheters are commonly used in various infusion therapies. For example, a catheter can be used to inject fluids such as saline, various drugs, and total parenteral nutrition into a patient. Also, a catheter can be used to collect blood from a patient.
[0003] A common type of catheter is an over-the-needle peripheral intravenous catheter ("PIVC"). As its name implies, an over-the-needle PIVC can be attached onto an introducer needle having a sharp distal tip. The PIVC and the introducer needle can be assembled such that the distal tip of the introducer needle extends beyond the distal tip of the PIVC with the needle bevel facing away from the patient's skin. The PIVC and the introducer needle are generally inserted at a shallow angle through the skin into a patient's blood vessel such as an artery, vein, or other vascular system of the patient. When the PIVC is properly positioned within the blood vessel, the introducer needle can be withdrawn and the PIVC can be fixed within the blood vessel by fixing a catheter adapter (coupled to the PIVC) to the patient's skin with a dressing. Other common types of catheters include, but are not limited to, a peripherally inserted central venous catheter ("PICC"), a central venous catheter ("CVC"), and the like.
[0004] A properly positioned catheter can be used by a clinician to collect blood from a patient. Furthermore, blood collection procedures are typically performed only with newly inserted catheters to avoid certain risks. For example, during a blood collection procedure, the clinician typically (1) inserts a new catheter / catheter adapter, (2) connects a blood collection device to the catheter adapter, (3) collects a blood sample from the patient using the blood collection device, (4) separates the blood collection device from the catheter adapter, (4) connects a flush device to the catheter adapter, (5) flushes the catheter / catheter adapter together with the flush device, and (6) separates the flush device from the catheter adapter.
[0005] However, each of these steps introduces complexity and inefficiency to the blood collection procedure (e.g., multiple connection / disconnection steps), restricts the procedure to a newly inserted catheter, and increases certain risks to the patient. Examples of potentially increased risks include drug contamination of the blood sample, hemolysis of the blood sample, increased risk of infection, increased risk of catheter occlusion, and increased risk of catheter migration.
[0006] The subject matter claimed herein is not limited to embodiments that resolve any shortcomings or embodiments that operate only in the environments described above. Rather, this background art is provided merely to illustrate an example of the technical area in which some of the embodiments described herein can be carried out. [Overview of the project]

[0031] The exemplary embodiments of this disclosure are best understood by reference to the drawings, and throughout the drawings, similar parts are designated by similar numbers. It will be readily apparent that the components of this disclosure, as generally described and illustrated in the drawings of this application, can be arranged and designed in a wide variety of different configurations. Accordingly, the following more detailed description of embodiments of devices and systems as shown in the drawings is representative of exemplary embodiments of this disclosure and is not intended to limit the scope of this disclosure as claimed in this application or in other applications claiming priority to this application.
[0032] Referring to Figures 1A and 1B, in some embodiments, the catheter system 10 may include a needle assembly 12 and a catheter assembly 14. Figures 1A and 1B show the catheter system in an insertion position, ready for insertion into a patient's vein (not shown). In some embodiments, the catheter assembly 14 may include a catheter adapter or catheter adapter body 16, which may include a proximal end 20, a distal end 18, and a catheter adapter channel 21 formed within the catheter adapter body 16 and extending between the proximal end 20 and the distal end 18 of the catheter adapter body 16. In some embodiments, the catheter adapter body 16 may include a septum 70 coupled to the catheter adapter body 16 adjacent to the catheter adapter channel 21. In some embodiments, the septum 70 may be a single-component septum. In some embodiments, the septum 70 may be a multi-component septum. In some embodiments, the catheter assembly 14 may include a catheter 22, which may include a proximal end 26, a distal end 24, and a catheter lumen 27 extending between the proximal and distal ends 26 and 24 of the catheter 22. In some embodiments, the catheter 22 may include a peripheral intravenous catheter ("PIVC"). In some embodiments, the proximal end 26 of the catheter 22 may be fixed within the catheter adapter body 16.
[0033] In some embodiments, the needle assembly 12 may include a needle hub 28 that can be removably coupled to the catheter adapter body 16. In some embodiments, the needle assembly 12 may include an introduction needle 30. In some embodiments, the proximal end 31 of the introduction needle 30 may be fixed within the needle hub 28. In some embodiments, the introduction needle 30 may extend through the catheter lumen 27, and the distal end 33 of the introduction needle 30 may protrude from the distal end 24 of the catheter 22 when the catheter system 10 is in the insertion position and ready to be inserted into the patient's vein.
[0034] In some embodiments, the needle assembly 12 may include a needle grip 32, and once the placement of the catheter 22 in the vein is confirmed, the clinician can grip the needle grip 32 and move it proximal to withdraw the introduction needle 30 from the vein. In some embodiments, the catheter system 10 may include an extension tube 34. In some embodiments, the distal end of the extension tube 34 may be coupled to the catheter adapter body 16, and the proximal end of the extension tube 34 may be coupled to the adapter 36. In some embodiments, the catheter adapter body 16 may include an access port 80, which may be in fluid communication with the catheter adapter channel 21. In some embodiments, the distal end of the extension tube 34 may be coupled to the access port 80 so that the extension tube 34 may be in fluid communication with the catheter adapter channel 21 via the access port 80.
[0035] In some embodiments, a fluid infusion device (not shown) may be coupled to an adapter 36 to deliver fluid to the patient via a catheter 22 inserted into a vein once the introduction needle 30 is removed from the catheter system 10. In some embodiments, a blood collection device may be coupled to an adapter 36 and can collect blood from the patient via a catheter 22 inserted into a vein.
[0036] The catheter system 10 may include straight, ported, integrated, and conventional catheters. In some embodiments, the catheter system 10 may be integrated, having an extension tube 34 integrated within the catheter adapter body 16, such as the BD NEXIVA® Closed IV Catheter System, the BD NEXIVA® DIFFUSICS® Closed IV Catheter System, the BD PEGASAUS® Safety Closed IV Catheter System, or another integrated catheter system. In some embodiments, the catheter system 10 may not be integrated without the extension tube 34.
[0037] In some embodiments, the catheter system 10 may be vented to observe blood and facilitate proximal blood flow in the introduction needle 30 and / or catheter 22. In some embodiments, the catheter system 10 may be vented in any suitable manner. For example, a vent plug 38 may be coupled to the adapter 36 when inserting the catheter 22 into the patient. In some embodiments, the vent plug 38 is permeable to air but not to blood. In some embodiments, the catheter 22, catheter adapter body 16, extension tube 34, adapter 36, and vent plug 38 may be in fluid communication. As another example, in some embodiments, the needle hub 28 may include a lavage chamber.
[0038] Figures 2A to 2E show various views of the protective needle housing 200 according to several embodiments. Specifically, Figure 2A is a perspective view of the protective needle housing 200, Figure 2B is a front view of the protective needle housing 200 in the closed position, Figure 2C is a front view of the protective needle housing 200 in the open position, Figure 2D is a cross-sectional side view of the protective needle housing 200 in the closed position, and Figure 2E is a cross-sectional side view of the protective needle housing 200 in the open position.
[0039] Generally, the protective needle housing 200 may include a needle block 220 comprising a proximal end 201, a distal end 202, an engagement mechanism 210 located at the distal end 202 of the protective needle housing 200, an engagement slot 212, a needle passage 240 extending between the proximal end 201 and the distal end 202 of the protective needle housing 200, a reduced inner diameter portion 242 of the needle passage 240 located at the proximal end 201 of the protective needle housing 200, and one or more of an opening 230, a first engagement surface 261, and an elastic member 250. The operation of the protective needle housing 200 will be described in more detail below with reference to Figures 4A-8.
[0040] Figures 3A to 3C show various views of the needle 300 according to several embodiments. Specifically, Figure 3A is a side view of the needle 300, Figure 3B is a close-up top view of the distal end of the needle 300, and Figure 3C is a close-up view of the middle portion of the needle 300.
[0041] Generally, the needle 300 may include a needle cannula 305 extending between the proximal end 301 and distal end 302 of the needle 300, a hub 340 coupled to the proximal end 301 of the needle 300, a closure tip 310 located at the distal end 302 of the needle 300, a suction opening 320 formed in the side wall of the needle cannula 305 located adjacent to the closure tip 310, and a bumper 330 coupled to the needle cannula 305. The operation of the needle 300 and the protective needle housing 200 will be described with reference to Figures 4A to 8.
[0042] Figures 4A and 4B show various diagrams of the protective needle housing system 400 according to several embodiments. Specifically, Figure 4A is a cross-sectional side view of the protective needle housing system 400 in the closed position, and Figure 4B is a cross-sectional side view of the protective needle housing system 400 in the open position. Generally, the protective needle housing system 400 may include the needles 300 shown in Figures 3A to 3C, which are slidably coupled within the protective needle housing 200 shown in Figures 2A to 2E.
[0043] The needle 300 may be supplementally held proximal within the protective needle housing 200 via a bumper 330 protruding from the needle cannula 305. The bumper 330 may have an outer diameter larger than the reduced inner diameter portion 242 of the needle passage 240. Thus, the bumper 330 may be configured to prevent the needle 300 from moving too far proximal in order to hold the needle 300 within the protective needle housing 200 when the clinician pulls the needle 300 proximal. The needle 300 may also be trapped distally within the protective needle housing 200 via the hub 340 through the needle block 200 when the needle block 220 is in the closed position (see Figure 4A) or when the needle block 220 is in the open position (see Figure 4B). Therefore, the needle block 220 and / or hub 340 can prevent the needle 300 from moving too far distally in order to hold the needle 300 within the protective needle housing 200 when the clinician pushes the needle 300 distally. In this way, the needle passage 240 and / or the narrowed inner diameter portion 242 of the needle passage 240 may each be configured to receive at least a portion of the needle 300, and trapping the closed tip 310 of the needle 300 within the protective needle housing 200 provides the clinician with an increased level of safety against accidental needle sticks. The closed tip 310 can also reduce hemolysis and reduce tears and contamination caused by the closed tip 310 puncturing through the septum.
[0044] As described above, the needle block 220 may be configured to move between a closed position (see, for example, Figures 2A, 2B, 2D, and 4A) and an open position (see, for example, Figures 2C, 2E, and 4B). In the closed position, the needle block 220 may prevent the needle 300 from advancing distally through the needle passage 240 by blocking the closed tip 310 of the needle 300, as shown in Figure 4A, thereby preventing the needle 300 from moving distally through the needle passage 240. In the open position, the opening 230 formed in the needle block 220 may be positioned aligned with the needle passage 240, as shown in Figure 4B, allowing the needle 300 to advance distally through the needle passage 240.
[0045] The elastic member 250 may be configured to apply a biasing force to the needle block 220 in order to preferentially bias the elastic member 250 to the closed position. In the embodiments shown in Figures 2A-2E, 4A, 4B, and 6-8, the elastic member 250 may include a spring clip configured to bias the needle block 220 to the upward / closed position. However, it is understood that other biasing structures are contemplated herein (see, for example, Figures 9A and 9B).
[0046] Figure 5 shows a cross-sectional side view of a catheter adapter 500 according to several embodiments. Generally, the catheter adapter 500 may include a catheter adapter body 516 and a catheter 522. The catheter adapter body 516 may include a proximal end 520, a distal end 518, a bottom surface 540, a top surface 542, and a catheter adapter channel 521 formed within the catheter adapter body 516 and extending between the proximal end 520 and the distal end 518 of the catheter adapter body 516. In some embodiments, the catheter adapter body 516 may include a first partition 571 and a second partition 572. The first partition 571 may be positioned toward the proximal end 520 of the catheter adapter body 516, and the second partition 572 may be coupled within the catheter adapter body 516 adjacent to the catheter adapter channel 521. A partition channel 575 may be formed between the first partition 571 and the second partition 572. In some embodiments, the partition 70 may be a multi-component partition. In some embodiments (not shown), the catheter adapter 500 partition may utilize a single-component partition. In some embodiments, the catheter adapter body 516 may also include an access port (not shown in Figure 5) which may be in fluid communication with the catheter adapter channel 521.
[0047] The catheter 522 may include a proximal end 526, a distal end 524, and a catheter lumen 527 extending between the proximal end 526 and the distal end 524 of the catheter 522. In some embodiments, the catheter 522 may include a peripheral intravenous catheter ("PIVC"). In some embodiments, the proximal end 526 of the catheter 522 may be coupled to and / or fixed to a catheter adapter body 516 so that the catheter lumen 527 can be in fluid communication with a catheter adapter channel 521.
[0048] Figures 6-8 show various diagrams of the catheter adapter 500 of Figure 5 coupled to the protective needle housing system 400 of Figure 4A, according to several embodiments. Specifically, Figure 6 is a cross-sectional side view of the catheter adapter 500 coupled to the protective needle housing system 400 in the closed position; Figure 7 is a cross-sectional side view of the catheter adapter 500 fully coupled to the protective needle housing system 400 in the open position; and Figure 8 is a cross-sectional side view of the catheter adapter 50 coupled to the protective needle housing system 400 in the open position, with the needle 300 moved distally and protruding inside the catheter adapter 500.
[0049] Figure 6 shows the proximal end 520 of the catheter adapter 500 when it is slidably received within the engagement mechanism 210 of the protective needle housing 200. When the proximal end 520 of the catheter adapter 500 is received within the engagement mechanism 210 of the protective needle housing 200, the first engagement surface 261 of the needle block 220 engages with the second engagement surface 262 formed on the proximal end 520 of the catheter adapter 500. The first engagement surface 261 of the needle block 220 and the second engagement surface 262 of the catheter adapter 500 can each be inclined in the proximal direction. In this way, the first engagement surface 261 can be configured to engage with the second engagement surface 262 of the catheter adapter 500, and when the second engagement surface 262 of the catheter adapter 500 engages with the first engagement surface 261 of the needle block 220, the needle block 220 moves from a closed position to an open position. Therefore, when the clinician fully connects the protective needle housing 200 to the catheter adapter 500 by moving the catheter adapter 500 in the direction of arrow 700, the needle block 220 can automatically move from the closed position to the open position, as shown in Figure 7. Once the needle block 220 is in the open position, the clinician can move the needle 300 distally and insert the needle 300 into the catheter adapter 500, as shown in Figure 8.
[0050] Figures 9A and 9B show two diagrams of the protective needle housing 900 according to an alternative embodiment. Specifically, Figure 9A is a front view of the protective needle housing 900 in the closed position, and Figure 9B is a front view of the protective needle housing 900 in the open position. In general, the protective needle housing 900 may include features and structures similar to those of the protective needle housing 200 shown in Figures 2A-2E, such as the engagement mechanism 910, the needle block 920, and the opening 930. However, the protective needle housing 900 may utilize an alternative structure including an elastic member 950 (e.g., a helical spring) and a needle block arm 970 to toggle the needle block 920 between the open and closed positions. The needle block 920 may also be configured to automatically move to the open position when coupled with the catheter adapter 500.
[0051] However, it will be understood that any number of different elastic member structures or configurations that can be used to switch the needle block between an open position and a closed position, and / or to bias the needle block toward the closed position are assumed herein. It will also be understood that any of the catheter adapter structures described herein, and / or any of the protective needle housing structures or systems disclosed herein, may be used in conjunction with any of the blood collection sets / systems described below.

[0053] The exemplary blood collection set 1000 shown in Figure 10 may generally include a first catheter adapter connector 1010, a first fluid conduit 1051, a second fluid conduit 1052, a third fluid conduit 1053, a first connector 1061, a first valve 1031, a second valve 1032, a first blood collection device 1021, and a irrigation device 1040.
[0054] The first catheter adapter connector 1010 may be configured to engage with a catheter adapter (not shown) in order to position the first catheter adapter connector 1010 in fluid communication with the catheter adapter. The catheter adapter may also include a catheter (not shown) that can be implanted in a patient's blood vessel. The first catheter adapter connector 1010, and any other catheter adapter connectors disclosed herein, may include at least one of needles, winged needle sets, needleless connectors (e.g., Q-SYTE® connectors, MAX ZERO® connectors, SMARTSITE® connectors, etc.), Luer lock connectors, Luer slip connectors, Luer taper connectors, extension sets, and / or extension tubes.

The catheter adapter may also include a catheter that can be placed in the patient's blood vessels.
[0109] Once the catheter adapter connector is coupled to the catheter adapter, method 1700 may proceed to step 1720, in which a first valve may be adjusted to allow fluid communication between at least one blood collection device and at least one catheter adapter connector. The at least one blood collection device may be configured to collect blood from a patient's blood vessel via a catheter, a catheter adapter, a catheter adapter connector, and one or more fluid conduits.
[0110] Once the first valve is adjusted to allow fluid communication between at least one blood collection device and at least one catheter adapter connector, the method 1700 may proceed to step 1730, in which blood can be drawn into at least one blood collection device via at least one catheter adapter connector.
[0111] Once blood has been drawn into at least one blood collection device via at least one catheter adapter connector, method 1700 may proceed to step 1740, adjusting a first valve to prevent fluid communication between the at least one blood collection device and the at least one catheter adapter connector.
[0112] Once the first valve is adjusted to prevent fluid communication between at least one blood collection device and at least one catheter adapter connector, the method 1700 may proceed to step 1750, in which case the second valve may be adjusted to allow fluid communication between the irrigation device and at least one catheter adapter connector.
[0113] Once the second valve is adjusted to allow fluid communication between the cleaning device and at least one catheter adapter connector, the method 1700 may proceed to step 1760, in which the catheter adapter may be cleaned with the fluid discharged from the cleaning device.
[0114] Alternatively, or in addition thereto, method 1700 may also include one or more of the following steps, which may be performed in any order: (1) step 1770, which may adjust a second valve to prevent fluid communication between a washing device and at least one catheter adapter connector and to allow fluid communication between a second blood collection device and at least one catheter adapter connector; and (2) step 1780, which may draw blood into the second blood collection device via at least one catheter adapter connector.
