Abstract
A method and apparatus are provided by which a fluid may be drawn and packaged within a series of interconnected sterile units. Once filled with the fluid, the connectors joining the sterile units may be sealed and severed to produce a number of separate sterile units. The volume of the separate sterile units may correspond to a single dose of the fluid. The technique allows a fluid to be partitioned into sterile units without exposure to the air or other potential contaminants.
Description
- This application is a divisional of U.S. application Ser. No. 10/272,650, filed Oct. 17, 2002, incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates generally to the field of storage of biomedical samples and fluids. More specifically, the invention relates to the sterile acquisition and storage of medications and bodily fluids in dosage packaging without exposing the fluids to air and contaminants.
- 2. Description of the Related Art
- This section is intended to introduce the reader to aspects of art that may be related to various aspects of the present invention, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present invention. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.
- The medical and research communities routinely acquire samples of bodily fluids, such as blood, and store such samples for subsequent use. Similarly, medications, drugs, or research compounds may be prepared and stored in large quantities but may need to be used in substantially smaller doses. In both instances, it is often desirable to provide the fluids in packaging which is easy to store and which corresponds to a usable amount, i.e., a single dose. In the process of placing the fluid into storage containers, however, it is desirable to prevent contact with the air or any other potential contaminant which would compromise the sterility of the fluid packaging.
- For example, if a blood sample is drawn from a patient for subsequent division and storage, a technician must either switch sample collection tubes during the process of drawing the blood in order to obtain multiple samples or must draw a single, larger sample which is subsequently divided. In both techniques, there is a risk of contamination due to exposure to air or contact with other non-sterile environments and/or instrumentation. To obviate these risks the sample may be heated or otherwise treated to minimize the risks of contamination. These additional steps may be undesirable and add a level of complexity to the process. It is therefore desirable to provide a means by which a fluid or sample may be obtained and separated into dosage storage containers without introducing the risks associated with air exposure and without necessarily requiring additional treatments, such as heating or irradiation.
- The foregoing and other advantages of the invention will become apparent upon reading the following detailed description and upon reference to the drawings in which:
-
FIG. 1 is a depiction of an apparatus for storing a fluid in the process of filling the sterile chambers of the apparatus with the fluid; -
FIG. 2 is a depiction of an apparatus for storing a fluid in which the sterile chambers of the apparatus are filled with the fluid; -
FIG. 3 is a depiction of an apparatus for storing a fluid in which connectors joining the sterile chambers of the filled apparatus have been sealed to form an airtight seal; -
FIG. 4 is a depiction of an apparatus for storing a fluid in which the filled sterile chambers of the apparatus have been separated at the airtight seals to form sealed individual doses of the fluid; and -
FIG. 5 is a depiction of one exemplary embodiment of the present technique in which a patient's blood is the fluid which is used to fill the apparatus for subsequent storage. - One or more specific embodiments of the present invention will be described below. Turning now to the drawings, and referring initially to
FIG. 1 , asterile assembly 10 is depicted which is connected to afluid source 12. Thefluid source 12 can include apressure regulator 14, here depicted as consisting of a piston action plunger cooperatively configured to apply pressure in an airtight manner to thefluid 16 within thefluid source 12. Alternate pressure regulation configurations are of course possible such as configuringpressure regulator 14 to create an area of negative pressure away from thefluid source 12, seeFIG. 5 , or combinations of positive and negative pressure within the apparatus. Typically any configuration of one ormore pressure regulators 14 which produce a relative negative pressure downstream withinsterile assembly 10 is acceptable. In instances in which thesterile assembly 10 is configured for drawing bodily fluids, thesterile assembly 10 may be created as a sterile vacuum or to inherently possess low relative pressure such that the bodily fluid is naturally drawn into thesterile assembly 10. - The
fluid source 12 also consists of afluid outlet 18 terminating in anairtight junction 20. Thefluid 16 flows through thefluid outlet 18 due to the pressure differential created by thepressure regulator 14. Thefluid 16 typically consists of a drug or medication stored in a stock supply or of a patient's bodily fluid. - In the present technique, the
sterile assembly 10 is connected to theairtight junction 20 via afluid inlet 22 which cooperatively engages thejunction 20. Thefluid inlet 22 provides fluid access to the remainder of the attachedassembly 10, which consists of at least twocompartments 24 joined together by aconnector 26 which, when open, allows thefluid 16 to flow between thecompartments 24. As depicted, thefluid inlet 22 is attached to anupstream terminal compartment 28. Likewise there is adownstream terminal compartment 30 from which thefluid 16 does not flow into anothercompartment 24. Asmany compartments 24 as necessary may be included in theassembly 10 in order to provide sufficient storage for the quantity offluid 16 desired. - Typically the
compartments 24 are sized such that they hold a single or multiple dose of thefluid 16 and are therefore uniformly sized in most applications. However, thecompartments 24 may be differently sized if the quantity comprising a single dose is to vary over the course of treatment, i.e., dosage gradually tapering off as treatment progresses. Thesterile assembly 10 is typically constructed from an airtight material, such as one of the various plastics utilized to make sterile biomedical storage containers. In one embodiment, the assembly is constructed of a sterile, flexible biomedical plastic which is vacuum vacated and sealed such that no contaminants or air are present in theassembly 10 prior to use. In this embodiment, thecompartments 24 expand as they are filled with thefluid 16. - As depicted in
FIG. 1 , thesterile assembly 10 is initially attached to thefluid source 12 via coupling thefluid inlet 22 to thejunction 20. Thefluid 16 is then introduced into theassembly 10 by the pressure differential created or maintained by thepressure regulator 14. While theapparatus 10 is being filled with thefluid 16, theconnectors 26 are open, allowing thefluid 16 to reach and fill all of thecompartments 24. - Once the
sterile assembly 10 is filled withfluid 16, as depicted inFIG. 2 , the pressure differential may be equilibrated via thepressure regulator 14. Once the pressure differential is equalized, theconnectors 26 are closed by forming anairtight seal 32 within theconnector 26, as depicted inFIG. 3 . In one embodiment of this technique, the biomedical plastic of which theconnectors 26 are composed is a heat-shrink plastic. Upon application of heat to theconnector 26, theconnector 26 shrinks in volume to form anairtight seal 32. In other embodiments, theconnector 26 may be composed of a pressure sensitive material such that pressure may be applied to form theairtight seal 32 or theconnector 26 may be constructed with engaging surfaces along the interior which engage to form an airtight seal when moved into contact. In other embodiments, a combination of heat and pressure may be used to affect the seal. Other means by which theairtight seal 32 may be formed exist and are within the scope of the described technique. - After
airtight seal 32 is formed, thecompartments 24 may separated from one another at theseal 32, as depicted inFIG. 4 . Due to theairtight seal 32, thefluid 16 is never exposed to the air and thus remains sterile. As depicted inFIG. 4 , thecompartments 24, once separated, formsterile storage containers 34 which may be stored as needed and which each contain a prescribed dose of thefluid 16, ready for use by a doctor or patient. Thesterile storage containers 34 consist of amain body 36 and one or more portions of sealedconnector 38 which remain associated with themain body 36 after separation. The portions of sealedconnector 38 provide easy access to thestored fluid 16, when needed, by either cutting or tearing. In this manner, a single or multiple dose of thefluid 16 may be provided for subsequent application to a patient, test subject or process. - In an alternative embodiment, the
sterile assembly 10, once filled, may be sealed by heat or pressure means at thefluid inlet 22. The sterile assembly may then be stored intact. During storage, theseals 32 may or may not be formed in therespective connectors 26. In this embodiment, prior to use or during storage, anairtight seal 32 is be formed in the desired connector and the respectivesterile storage container 34 may then be removed from thesterile assembly 10 for use. - In this embodiment a sealing device may be configured to create an
airtight seal 32 which does not break symmetrically. The configured sealing device may apply heat, pressure, or a combination of the two via clamping section to form the asymmetric seal. The clamping section is typically configured to conform to the shape of the connector when loose and may tighten to deform the connector as pressure and/or heat are applied. Heat may be generated by elements within the clamping section which utilize infrared, RF, electrical, or chemical energy or other heat generating methods known in the art. - The
airtight seal 32 which is created may be formed to break such that thecompartments 24 remaining connected to thesterile assembly 10 remain airtight, and thus sterile, while thestorage container 34 which is removed is open and ready for use due to the asymmetry of theairtight seal 32 formed. In this manner a filledsterile assembly 10 may be filled, stored and sealed such that, when desired, asterile storage containers 34 may be removed from theassembly 10 ready for use. - In one exemplary embodiment, the fluid 16 is a patient's
blood 36. In this embodiment, theassembly 10 can be utilized while the patient'sblood 36 is drawn, as depicted inFIG. 5 . Theapparatus 10 in this embodiment can utilize negative pressure to fill thecompartments 24 with theblood 36 without allowing exposure to the air. In particular, apressure regulator 14 may be operatively coupled to theterminal compartment 30 to create negative pressure to draw the blood into theapparatus 10. Thepressure regulator 14 may operate on a piston principle. Alternately, theapparatus 10 itself may be formed and stored as a vacuum such that the negative pressure of the vacuum draws the blood into it once connected to the patient. As with the previously described embodiment, once theapparatus 10 is filled, theconnectors 26 joining thecompartments 24 to each other and to thefluid inlet 22 andpressure regulator 14 are sealed and then separated. Once separated, the storage containers of blood may be stored and subsequently used for medicinal purposes, such as for the treatment of certain eye disorders. - While the invention may be susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and will be described in detail herein. However, it should be understood that the invention is not intended to be limited to the particular forms disclosed. Rather, the invention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the invention as defined by the following appended claims. Illustrative embodiments of the present claimed subject matter are described in detail below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of the present disclosure.
