Any embodiment of any of the present containment assemblies, methods, and kits can consist of or consist essentially of—rather than comprise/include/contain/have—any of the described elements and/or features. Thus, in any of the claims, the term “consisting of” or “consisting essentially of” can be substituted for any of the open-ended linking verbs recited above, in order to change the scope of a given claim from what it would otherwise be using the open-ended linking verb.
The feature or features of one embodiment may be applied to other embodiments, even though not described or illustrated, unless expressly prohibited by this disclosure or the nature of the embodiments.
Details associated with the embodiments described above and others are presented below.
The following drawings illustrate by way of example and not limitation. For the sake of brevity and clarity, every feature of a given structure is not always labeled in every figure in which that structure appears. Identical reference numbers do not necessarily indicate an identical structure. Rather, the same reference number may be used to indicate a similar feature or a feature with similar functionality, as may non-identical reference numbers. The figures illustrate the described elements using graphical symbols that will be understood by those of ordinary skill in the art. The embodiments of the present containment assemblies and their components shown in the figures are drawn to scale for at least the embodiments shown.
The term “coupled” is defined as connected, although not necessarily directly, and not necessarily mechanically. Two items are “couplable” if they can be coupled to each other. Unless the context explicitly requires otherwise, items that are couplable are also decouplable, and vice-versa. One non-limiting way in which a first structure is couplable to a second structure is for the first structure to be configured to be coupled (or configured to be couplable) to the second structure. The terms “a” and “an” are defined as one or more unless this disclosure explicitly requires otherwise. The term “substantially” is defined as largely but not necessarily wholly what is specified (and includes what is specified; e.g., substantially 90 degrees includes 90 degrees and substantially parallel includes parallel), as understood by a person of ordinary skill in the art. In any disclosed embodiment, the terms “substantially,” “approximately,” and “about” may be substituted with “within [a percentage] of” what is specified, where the percentage includes 0.1, 1, 5, and 10 percent.
The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include” (and any form of include, such as “includes” and “including”) and “contain” (and any form of contain, such as “contains” and “containing”) are open-ended linking verbs. As a result, a containment assembly or a kit, or components of a containment assembly or a kit that “comprises,” “has,” “includes” or “contains” one or more elements or features possesses those one or more elements or features, but is not limited to possessing only those elements or features. Likewise, a method that “comprises,” “has,” “includes” or “contains” one or more steps possesses those one or more steps, but is not limited to possessing only those one or more steps. Additionally, terms such as “first” and “second” are used only to differentiate structures or features, and not to limit the different structures or features to a particular order.
Further, a containment assembly and kits and methods comprising containment assemblies configured in a certain way are configured in at least that way, but can also be configured in other ways than those specifically described. Embodiments of the present powered drivers may be used to insert an IO device into a selected target area or target site in ten seconds or less. However, various teachings of the present disclosure are not limited to use with powered drivers. Manual drivers and spring powered drivers may also be used with IO devices and embodiments of the present containment assemblies incorporating teachings of the present disclosure.
Various types of coupler assemblies incorporating teachings of the present disclosure may be satisfactorily used to releasably engage one end of a shaft extending from a driver with one end of an intraosseous device. For some embodiments, the powered driver may include a driveshaft having one end with a generally hexagonal cross section operable to be releasably engaged with a latch mechanism disposed in one end of a coupler assembly. For some embodiments, a coupler assembly incorporating teachings of the present disclosure may be referred to as a “hands free” coupler, a quick disconnect or quick release coupler and/or port assembly.
Examples of manual drivers are shown in co-pending patent application Ser. No. 11/042,912 entitled Manual Intraosseous Device filed Jan. 25, 2005 (published as US 2005/0165404). The term “fluid” may be used in this application to include liquids such as, but not limited to, blood, water, saline solutions, IV solutions, plasma, or any mixture of liquids, particulate matter, dissolved medication, and/or drugs associated with biopsy or aspiration of bone marrow or communication of fluids with bone marrow or other target sites. The term “fluid” may also be used in this patent application to include any body fluids and/or liquids containing particulate matter such as bone marrow and/or cells which may be withdrawn from a target area.
The terms “harvest” and “harvesting” may be used in this application to include bone and/or bone marrow biopsy and bone marrow aspiration. Bone and/or bone marrow biopsy (sometimes referred to as “needle biopsy”) may be generally described as removing a relatively small piece or specimen of bone and/or bone marrow from a selected target area for biopsy purposes. Bone marrow aspiration (sometimes referred to as “bone marrow sampling”) may be generally described as removing larger quantities of bone marrow from a selected target area. Relatively large quantities of bone marrow may be used for diagnostic, transplantation, and/or research purposes. For example some stem cell research techniques may require relatively large quantities of bone marrow.
The term “insertion site” may be used in this application to describe a location on a bone at which an intraosseous device may be inserted or drilled into the bone and associated bone marrow. Insertion sites are generally covered by skin and soft tissue. The term “target area” refers to any location on or within biological material, such as the biological material of a living human being.
The term “intraosseous (IO) device” may be used in this application to include, but is not limited to, any hollow needle, hollow drill bit, penetrator assembly, bone penetrator, catheter, cannula, trocar, stylet, inner penetrator, outer penetrator, IO needle, biopsy needle, aspiration needle, IO needle set, biopsy needle set or aspiration needle set operable to provide access to an intraosseous space or interior portions of a bone. Such IO devices may be formed, at least in part, from metal alloys such as 304 stainless steel and other biocompatible materials associated with needles and similar medical devices.
Embodiments of the present containment assemblies can be included in medical procedure trays such as those disclosed in International Patent Application No. PCT/US2007/078207 (published as WO 2008/033874).
The devices and components shown in
Referring now to the drawings, and more particularly to
In the embodiment shown, cannula 110a includes a plurality of markings 104 disposed on exterior portions of the cannula. Markings 104 may be referred to as “positioning marks” or “depth indicators,” and may be used to indicate the depth of penetration of needle set 100 into a bone and associated bone marrow. In some embodiments, cannula 110a may have a length of approximately sixty (60) millimeters and/or a nominal outside diameter of approximately 0.017 inches (e.g., corresponding generally to the dimensions of a sixteen (16) gauge needle). Cannula 110a and/or stylet 120 may be formed from stainless steel or other suitable biocompatible materials. In some embodiments, markings 104 are spaced at one (1) centimeter intervals on exterior portions of cannula 110a. In some embodiments, one or more side ports 106 may be formed in exterior portions of cannula 110a spaced from first end 111a.
Hub assembly 130a may be configured and/or used to releasably dispose stylet 120 within the longitudinal bore or lumen of cannula 110a. In the embodiment shown, hub assembly 130a includes a first hub 140a and a second hub 150a. A second end of cannula 110a, opposite from first end 111a, may be securely engaged with hub 140a. The second end of stylet 120, opposite from first end 121, may be securely engaged with the first end of hub 150a. As shown in
In the embodiment shown, the second end of a hub assembly may be operable to be disposed within a receptacle formed in a coupler assembly, as described in more detail below. One feature of the present disclosure may include forming a hub assembly which may be releasably engaged within a first receptacle disposed in a first end of a coupler assembly (e.g., receptacle 263 proximate first end 261 of elongated core 260 as shown in
In the embodiment shown, intraosseous device or aspiration needle set 100a includes first end 151 of hub 150a spaced from second end 142 of hub 140a. Portions of stylet 120 extending from first end 151 of hub 150a are shown slidably disposed within lumen or longitudinal bore 118 of cannula 110a. Hub assembly 130a may include first end 131 which may correspond generally with first end 141 of hub 140a. Hub assembly 130a may also include second end 132 which may correspond generally with second end 152 of hub 150a and second end 102 of hub assembly 130a, as shown. Cannula 110a may be attached to and extend from first end 141 of hub 140a. Second end 142 of hub 140a may include one-half a typical Luer lock connection or fitting operable to be releasably engaged with corresponding portions of a Luer lock connection or fitting disposed in first end 151 of second hub 150a. For embodiments such as the one shown in
At least one portion of hub assembly 130a may have a generally hexagonal cross section operable to be received within the generally hexagonal cross section of receptacle 263 disposed proximate first end 251 of coupler assembly 250, as shown in
Hub 140a may include second end 142 with opening 144 formed therein. A passageway may extend from second end 142 towards first end 141 of hub 140a, as illustrated in
For some applications hub 140a and hub 150a may, for example, be formed using injection molding techniques. For such embodiments hub 140a may include reduced outside diameter portion 143 disposed between first end 141 and second end 142. In a similar manner a plurality of void spaces or cutouts 153 may be formed in hub 150a adjacent to and extending from second end 152 in the direction of first end 151. The configuration and dimensions of reduced diameter portion 143 and/or cutouts 153 may be varied to optimize associated injection molding techniques and at the same time provide required configurations, dimensions and material strength to allow associated hub assembly 130a to function as described in this disclosure.
In some embodiments, tip 123 of stylet 120 may be disposed relatively close to a tip of cannula 110a. For some applications, first end 121 of stylet 120 and first end 111a of cannula 110a may be ground at the same time to form adjacent cutting surfaces. Grinding ends 111a and 121 at the same time may result in forming a single cutting unit to form generally matching cutting edges. Other types of cutting surfaces formed in accordance with teachings of the present disclosure may be discussed later (e.g., as described with reference to
As shown in
Motor 218 and gear assembly 220 may be disposed within portions of housing 210 adjacent to handle 214. Motor 218 and gear assembly 220 may be generally aligned with each other. Motor 218 may be rotatably engaged with one end of gear assembly 220. Drive shaft 222 may be rotatably engaged with and extend from another end of gear assembly 220 opposite from motor 218. For some applications both motor 218 and gear assembly 220 may have generally cylindrical configurations. Distal end or first end 211 of housing 210 may include an opening with portions of drive shaft 222 extending through the opening, as shown. For some applications, end 224 or the portion of drive shaft 222 extending from first end 211 of housing 210 may have a generally hexagonal cross section with surfaces 226 disposed thereon. Receptacle 263 disposed in second end 252 of coupler assembly 250 may have a matching generally hexagonal cross section, as shown in
Surfaces 226 may extend generally parallel with each other and parallel with respect to a longitudinal axis or rotational axis of drive shaft 222. One or more tapered surfaces 228 may also be formed on end 224 to assist with releasably engaging powered driver 200 with coupler assembly 250. Embodiments of powered driver 200 include speed reduction ratios, for example, of between 60:1 and 80:1, resulting in drive shaft RPMs that are reduced relative to motor RPMs. Coupler assemblies having corresponding openings or receptacles may be releasably engaged with end 224 extending from first end 211 of powered driver 200. For example, end 224 extending from first end 211 of housing 210 may be releasably engaged with receptacle 264 disposed proximate second end 252 of coupler assembly 250, as shown in
For some applications thrust bearing 241 may be disposed between first end or distal end 211 of housing 210 and adjacent portions of gear assembly 220. Thrust bearing 242 may be disposed between second end or proximal end 212 of housing 210 and adjacent portions of motor 218. Thrust bearings 241 and 242 may limit longitudinal movement of motor 218, gear assembly 220 and drive shaft 222 within associated portions of housing 210. Trigger assembly 244 may also be disposed within housing 210 proximate handle 214. Trigger assembly 244 may include trigger or contact switch 246. Motor 218 may be energized and deenergized by alternately depressing and releasing trigger 246. Electrical circuit board 247 may also be disposed within housing 210. Electrical circuit board 247 may be electrically coupled with trigger assembly 244, motor 218, power supply 216 and indicator light 248. For some applications indicator light 248 may be a light emitting diode (LED) or a small more conventional light bulb. For some applications indicator light 248 may be activated when ninety percent (90%) of electrical storage capacity of battery pack 216 has been used. The configuration and dimensions of an intraosseous device formed in accordance with teachings of the present disclosure may vary depending upon respective intended applications for each intraosseous device. For example the length of a biopsy needle formed in accordance with teachings of the present disclosure may vary from approximately five (5) millimeters to thirty (30) millimeters.
Coupler assemblies incorporating teachings of the present disclosure may function as “quick release mechanisms” operable to engage and disengage an IO device from a powered driver (e.g., a driver disposed within a flexible containment bag or sterile sleeve). Such coupler assemblies may allow rotation of an IO device (e.g., biopsy needle or needle set) without damage to the flexible containment bag or sterile sleeve. One end of the coupler assembly may be operable to form a fluid seal or fluid barrier with adjacent portions of the containment bag or sterile sleeve. A coupler assembly incorporating teachings of the present disclosure may also be described as a port assembly attached to a containment bag. Such port assemblies may allow easy engagement or disengagement of a powered driver from an IO device and at the same time allow the powered driver to “power in and power out” an IO device from an insertion site.
Coupler assemblies incorporating various teachings of the present disclosure may be placed in a medical procedure tray or kit with one end down and an opposite end looking up to allow “hands free” releasable engagement with a powered driver or a manual driver. For example, coupler assembly 250a may be disposed in medical procedure tray with first end 251 facing downward and second end 252 facing up such that end 224 of drive shaft 222 (of driver 200) may be inserted into and releasably engaged with second end 252 of coupler assembly 250 without requiring an operator or user to physically contact or manipulate any portion of coupler assembly 250a. As described below, coupler 250a may include a “hands free” latching mechanism.
In the embodiment shown, coupler assembly 250a may include elongated core 260 with housing assembly 270 slidably disposed on exterior portions of elongated core 260. Housing assembly 270/270a may include first end 271 and second end 272 which may be generally aligned with respective first end 261 and respective second end 262 of elongated core 260. For some applications, elongated core 260 may have a generally cylindrical configuration defined in first exterior portion 260a and second exterior portion 260b with various shoulders and/or recesses formed thereon. For some embodiments first exterior portion 260a may have a larger diameter than second exterior portion 260b. Housing assembly 270 may be described as having a generally hollow, cylindrical configuration defined in part by first housing segment 280 and second housing segment 290. The first end of housing segment 280 may generally correspond with first end 271 of housing assembly 270. The second end of second housing segment 290 may generally correspond with second end 272 of housing assembly 270. First end 291 of second housing segment 290 may be described as having a generally cylindrical configuration with an outside diameter smaller than the adjacent inside diameter of second end 282 of first housing segment 280. Second housing segment 290 may slide longitudinally from a first position (
A biasing mechanism such as coiled spring 274 may be disposed around exterior portion 260a of generally elongated core 260. First end 275 of coiled spring 274 may contact annular shoulder 284 formed on interior portions of first housing segment 280. Second end 276 of coiled spring 274 may contact annular shoulder 278 disposed proximate first end 291 of second housing segment 290. Coil spring 274, annular shoulder 284 and annular shoulder 278 may cooperate with each other to generally maintain first housing segment 280 and second housing segment 290 in a first extended position relative to each other. Other biasing mechanisms such as, but not limited to, leaf springs and bellows (not expressly shown) may also be disposed between annular shoulder 284 and annular shoulder 278. Annular shoulder 278, associated with second end 276 of coiled spring 274, may extend radially outward from generally cylindrical ring 277. Generally cylindrical ring 277 may be slidably and rotatably disposed on exterior portion 260a of elongated core 260. Annular shoulder 279 may be disposed on interior portions of generally cylindrical ring 277 and may extend radially inward toward adjacent portions of elongated core 260. Annular shoulder 268 may be formed on exterior portion 260a of elongated core 260 intermediate first end 261 and second end 262. The configuration and dimensions of annular shoulder 268 and annular shoulder 279 are selected to be compatible with each other such that engagement between annular shoulder 279 of generally cylindrical ring 277 with annular shoulder 268 of elongated core 260 may limit movement of second housing segment 290 longitudinally in the direction of second end 262 of elongated core 260.
For some applications a plurality of flexible collets or fingers 477 may extend from generally cylindrical ring 277 opposite from annular shoulder 278. Respective collet heads 478 may be formed on the end of each collet 477 opposite from annular shoulder 278. The dimensions and configuration of collet heads 478 may be selected to be received within respective slots or openings 297 formed in second housing 290. During manufacture of coupler assembly 250a, each collet head 478 may be disposed within respective slot or opening 297 to securely engage generally cylindrical ring 277 and annular shoulder 278 proximate first end 291 of second housing segment 290. As a result, second housing segment 290 and annular shoulder 278 may generally move as a single unit relative to elongated core 260 and first housing segment 280. During disengagement of an intraosseous device from first end 251 of coupler assembly 250a, first housing segment 280 may move or slide longitudinally toward second housing segment 290. In a similar manner, second housing segment 290 may move or slide longitudinally toward first housing segment 280 during disengagement of a powered driver from second end 252 of coupler assembly 250a.
Annular shoulder 267 may be formed on exterior portions of elongated core 260 proximate first end 261. Annular shoulder 267 may engage portions of first end 271 of housing 270 to limit longitudinal movement of first housing segment 280 during longitudinal movement of second housing segment 290 towards first end 261 of elongated core 260 during disengagement of a powered driver from second end 252 of coupler assembly 250a. As previously noted, annular shoulder 268 may be formed on exterior portions of elongated core 260 between first end 261 and second end 262. Engagement between annular shoulder 268 and annular shoulder 279 of generally cylindrical ring 277 may limit movement of second housing segment 290 toward second end 262 of elongated core 260. Contact between spring 274 and annular shoulder 278 and annular shoulder 284 of first housing segment 280 may limit the longitudinal movement of first housing segment 280 in the direction of second end 262 of elongated core 260 during disengagement of an intraosseous device from first end 251 of coupler assembly 250a.
Generally cylindrical ring 277 and attached annular shoulder 279 may slide longitudinally on exterior portions of annular core 260 between annual shoulder 268 and annular shoulder 267. First housing segment 280 may move longitudinally toward second end 262 of elongated core 260 to release one end of intraosseous device from engagement with first end 251 of coupler assembly 250a. In a similar manner, second housing segment 290 may move longitudinally toward first end 261 of elongated core 260 to release one end of a drive shaft extending from a powered driver engaged with second end 252 of coupler assembly 250a. A wide variety of latches and latch mechanisms may be satisfactorily used to releasably engage one end of an intraosseous device within a first end of a coupler assembly incorporating teachings of the present disclosure. In a similar manner, a wide variety of latches and latch mechanisms may be satisfactorily used to releasably engage one end of a drive shaft extending from a powered driver or manual driver within a second end of the coupler assembly incorporating teachings of the present disclosure.
For embodiments represented by coupler assembly 250a, first latch 410 may be disposed on exterior portions of elongated core 260 proximate receptacle 263 adjacent to first end 261 to releasably engage one end of an IO device such as second end 102 of biopsy needle set 100b within receptacle 263 of coupler assembly 250a. Second latch mechanism 420 may be disposed on exterior portions of elongated core 260 proximate receptacle 264 adjacent to second end 262 to releasably engage one end of a drive shaft with second end 252 of coupler assembly 250a. Second latch 420 may be used to releasably engage one portion of a drive shaft such as end 224 of drive shaft 222 extending from powered driver 200 within second end 252 of coupler assembly 250a. Latch 410 may releasably engage an intraosseous device with first end 251 of coupler assembly 250a and substantially the same latch 420 may releasably engage a powered driver with second end 252 of coupler assembly 250a.
For some applications, latches 410 and 420 may have similar configurations such as a general “omega” shape (e.g., latch 420). However, latch 410 may have larger dimensions corresponding generally with exterior portion 260a of elongated core 260. Latch 420 may have smaller dimensions corresponding generally with exterior portion 260b of elongated core 260. Various features of the present disclosure may be described with respect to latch mechanism 420 along with adjacent portions of second housing segment 290 and exterior portion 260b of elongated core 260. Respective detents 421 and 422 may be formed on opposite ends of generally omega shaped latch 420. In a similar manner, respective detents (not expressly shown) may be formed on the ends of generally omega shaped latch 410. The configuration and dimensions of detents 421 and 422 may be compatible with placing each detent 421 and 422 in a respective slot or opening extending between exterior portion 260b of elongated core 260 to interior portions of receptacle 264 disposed proximate second end 252 of coupler assembly 250a. Latch 420 may have a first position in which portions of detents 421 and 422 may extend through the respective slots. The dimensions and configuration of detent 421 and 422 may be operable to be securely engaged with annular groove 402 formed in end 224 of powered driver 200. In a similar manner, respective detents on associated latch 410 may be releasably engaged with annular groove 401 disposed in second end 102 of biopsy needle 100b. For some applications, a plurality of tapered surfaces 403 may be formed on exterior portions of hub 140a proximate first end 142 to radially expand detent mechanisms associated with omega shaped latch 410 radially outward while inserting second end 102 of biopsy needle 100b into first end 251 of coupler assembly 250a. The detent mechanism may “snap” into annular groove 401 when aligned therewith. In a similar manner, a plurality of tapered surfaces 228 may be formed on exterior portions of end 224 of drive shaft 222 extending from powered driver 200 to radially expand detent mechanisms 421 and 422 radially outward during the insertion of end 224 of powered driver 200 into second end 252 of coupler assembly 250a. Detent mechanisms 421 and 422 will “snap” into annular groove 402 when aligned therewith.
Engagement between detent mechanisms associated with latch 410 with annular groove 401 of hub assembly 130a will generally retain second end 102 of biopsy needle 100b securely engaged with first end 251 of coupler assembly 250a. This engagement may allow powered driver 200 to rotate or spin cannula or biopsy needle 110b while withdrawing cannula or biopsy needle 110b from an insertion site. In a similar manner, engagement between detent mechanisms 421 and 422 of omega shaped latch 420 and annular groove 402 of end 224 of powered driver 200 will generally retain second end 252 of coupler assembly 250a engaged with powered driver 100 during withdrawal of cannula 110b from an insertion site.
Biopsy needle set 100b may be released from first end 251 of coupler assembly 250a by sliding first housing segment 280 longitudinally toward second end 262 of elongated core 260. Such movement of first housing segment 280 will result in interior tapered surface 286 contacting exterior portions of omega shaped latch 410 and compressing omega shaped latch 410 to radially expand associated detent mechanisms (not expressly shown) from engagement with annular groove 401 of hub assembly 130a. As a result, biopsy needle set 100b may be easily withdrawn from first end 251 of coupler assembly 250a. In a similar manner, longitudinal movement of second housing segment 290 toward first end 251 of coupler assembly 250a will result in interior tapered surface 296 contacting exterior portions of omega shaped latch 420 to compress generally omega shaped latch 420 and withdraw or retract detent mechanisms 421 and 422 from engagement with annular groove 402 of end 224. As a result, powered driver 200 and second end 222 of coupler assembly 250a may be easily disconnected from each other.
Flange 254 may be generally described as having an enlarged funnel shaped or bell shaped configuration. The dimensions and configuration of flange 254 may be selected to be compatible with end 211 of powered driver 200. As previously noted, coupler assembly 250a may be securely engaged with an opening formed in a containment bag or sterile sleeve in accordance with teachings of the present disclosure. For embodiments such as the one shown, end 272 of housing 270 of coupler assembly 250a may include annular ring 370 operable to be securely engaged with adjacent portions of flange 254. The outside diameter of annular ring 370 may generally correspond with the outside diameter of adjacent portions of flange 254. The inside diameter of annular ring 370 may also generally correspond with the inside diameter of adjacent portions of flange 254. For some embodiments a plurality of posts 372 and generally V shaped grooves 374 may be alternatingly disposed on the extreme end of flange 254. Annular ring 370 may include a plurality of holes 371 sized to received respective posts 372 therein. Annular ring 370 may also include a plurality of generally V shaped projections 376 sized to be received within respective generally V shaped grooves 374 formed in adjacent portions of flange 254. For embodiments such as the one shown, portions of a containment bag (e.g., around an opening) may be disposed between annular ring 370 and adjacent portions of flange 254. For example, post 372 may be inserted through a corresponding hole in a containment bag adjacent to the perimeter of an opening in the containment bag. Holes 371 in annular ring 370 may be aligned with respective posts 372. Other portions of a containment bag (e.g., adjacent to an opening) may be trapped between respective V shaped projections 376 and V shaped grooves 374. Various welding techniques including, but not limited to, laser welding may be applied to posts 372 to bond annular ring 370 with adjacent portions of flange 354. As a result, a perimeter of a containment bag around an opening in the containment bag may be securely engaged with second end 252 of coupler assembly 250a.
Medical procedure trays and/or kits formed in accordance with teachings of the present disclosure may provide a support or base for various components such as a coupler assembly, funnel, and/or sharps protector to allow an operator or user to perform various functions without requiring that the operator or user hold or manipulate the respective component. For example, medical procedure tray 20c as shown in
Medical procedure trays 20a, 20b and/or 20c may also contain a wide variety of other components including, but not limited to, one or more sharps protectors 64 as shown in

The present containment assemblies depict various embodiments of closable/sealable containment bags and structural features of containment assemblies operable to close and/or seal a containment bag with a driver in the interior of the containment bag. For example, in the embodiment shown in
In some embodiments of the containment assemblies in
Some embodiments of the present methods, which include methods involving the use of containment assemblies (e.g., sterilized containment assemblies), include inserting a driver (e.g., driver 526) into a containment bag (e.g., containment bag 530a) of a containment assembly (e.g., containment assembly 510a), and coupling the driver to a coupler (e.g., second end 522 of coupler 514) that is coupled to the containment bag. The containment bag has an opening (e.g., second opening 546a), and it also has a rod (e.g., rod 550) that is positioned farther from the driver than is the opening. These embodiments also include rotating the rod toward the coupler to close the opening. In some more specific embodiments, the method can also include coupling an intraosseous needle set/device to the coupler (e.g., first end 518) and activating the driver to move (e.g., rotate) the intraosseous needle set/device.
In the embodiment shown in
Some embodiments of the present methods, which include methods involving the use of containment assemblies (e.g., sterilized containment assemblies), include inserting a driver (e.g., driver 526, where the driver can be sterile or non-sterile) into a containment bag having an open end (e.g., containment bag 530b) of a containment assembly (e.g., containment assembly 510b), coupling the driver to a coupler (e.g., second end 522 of coupler 514) that is coupled to the containment bag, and moving a tab (e.g., tab 566) in a first direction to cause a first lockable track (e.g., lockable track 558) to engage a second lockable track (e.g., lockable track 562) to close an opening (e.g., second opening 546b) in the containment bag to enclose and/or seal the driver in the interior of the containment bag. In some more specific embodiments, the method can further comprise coupling an intraosseous needle set/device to the coupler and activating the driver to move the intraosseous needle set/device. In other embodiments, the method can include moving the tab in a second direction (e.g., opposite the first direction) to cause the first lockable track to disengage the second lockable track to open the opening in the containment bag (e.g., to permit a user to decouple and/or remove the driver).
In the embodiment shown, containment bag 530c can be in a folded configuration (e.g.,
Some embodiments of the present methods, which include methods involving the use of containment assemblies (e.g., sterilized containment assemblies), include inserting a driver (e.g., driver 526, where the drive can be sterile or non-sterile) into a containment bag having an open end (e.g., containment bag 530c) of a containment assembly (e.g., containment assembly 510c), coupling the driver to a coupler (e.g., second end 522 of coupler 514) that is coupled to the containment bag, and pulling at least one drawstring (e.g., at least one drawstring 570) to cinch the containment bag to close an opening (e.g., second opening 546c of containment bag 530c) in order to enclose and/or seal the driver in the interior of the containment bag. In some embodiments, if the containment bag is prevented from moving to an unfolded configuration by at least one retaining strip (e.g., at least one retaining strip 578) coupled to the containment bag, then the method can include applying a sufficient force to decouple the at least one retaining strip from the containment bag to permit the containment bag to move into the unfolded configuration. In some embodiments, the method can include tying two ends of the at least one drawstring (e.g., when the at least one drawstring has two ends) and/or tying two or more drawstrings (e.g., when more than one drawstring is coupled to the containment bag) together to keep the opening of the containment bag closed. In some more specific embodiments, the method can further comprise coupling an intraosseous needle set/device to the coupler and activating the driver to move the intraosseous needle set/device.
Some embodiments of the present methods, which include methods involving the use of containment assemblies (e.g., sterilized containment assemblies), include inserting a driver (e.g., driver 526, where the driver can be sterile or non-sterile) into a containment bag having an open end (e.g., containment bag 530d) of a containment assembly (e.g., containment assembly 510d), coupling the driver to a coupler (e.g., second end 522 of coupler 514) that is coupled to the containment bag, rolling the containment bag to move the containment bag to an unrolled configuration (e.g., by rolling second end 542d of containment bag 530d away from first end 534d), and closing the open end of the containment bag. In some embodiments, the method can include tying the containment bag (e.g., second end 542d of containment bag 530d) to seal the driver in the interior of the containment bag. In some more specific embodiments, the method can include coupling an intraosseous needle set/device to the coupler (e.g., first end 518 of coupler 514) and activating the driver to move the intraosseous needle set/device.
In addition to containment bags, the present containment assemblies can also include substantially rigid casings. A substantially rigid casing—similarly to a containment bag—can be configured to prevent a driver from desterilizing a sterile intraosseous device and/or target area. For example, in the embodiment shown in
