Holders for syringes and other medical instruments

Abstract

The medical instrument holder has a base block configured for removably mounting to a mounting surface, the base block having protrusions extending therefrom. A receiving block formed of a pliable material that is soft and resilient (e.g., elastic foam) may be impaled on the protrusions. A medical instrument (e.g., a syringe or scalpel) may be inserted into the receiving block, which may effectively removably hold the medical instrument against the mounting surface. The receiving block may be discarded after use and replaced with another receiving block for subsequent use. The holder is particularly useful for receiving the cap of a hypodermic syringe in the receiving block, allowing the syringe to be held in a ready-to-use position and allowing one-handed removal of the syringe from the cap gripped by the receiving block.

Description

[Technical Field]

[0001] This document relates generally to an invention relating to holders for medical instruments, particularly for hypodermic syringes, and more particularly to an instrument holder that allows an instrument, such as a hypodermic syringe, to be grasped and held using one hand. [Background technology]

[0002] In the medical field, there is often a need to keep instruments ready for use while preventing potential injury or contamination of such instruments. As an example, syringe holders have been developed that hold syringes in a ready-to-use position by gripping the syringe's cap. The syringe cap covers the syringe needle when the syringe is not in use to maintain sterility and prevent accidental needle sticks. These holders allow the user to pull the syringe out of the cap to expose the needle for use, then replace the needle within the gripped cap and attach the syringe for later use as needed. Examples can be found in prior patents such as: US4846803 (Emerson), US4938354 (Hernandez), US4986817 (Code), US5078695 (Farrar, Jr. et al.), US5797885 (Rubin), US7975846 (Clegg et al.), WO199302871 (Collett), EP0510626 (HerotecKunststoffverarbeitung), and FR2664816 (Cabinet Ores.). Other examples are: Soft Soft foam syringe / scalpel holder Examples include those found in WO2007065110 and those offered by Aspen Surgical (Caledonia, MI, USA) and Quosina Corporation (Ronkonkoma, NY, USA).The Aspen holder is a rectangular prism (e.g., a cube-like block) formed of flexible foam with double-sided tape on its bottom, allowing the backing sheet to be removed from the tape and then adhered to a surgical drape. A syringe cap can then be inserted into a small hole formed in the top of the prism, or simply forced into the foam so that it penetrates the prism, with the foam's elasticity tending to retain the inserted cap. The syringe can then be withdrawn from the cap held within the attached prism and used, and the syringe needle can be reinserted into the cap when use is complete. Quosina offers a similar holder, as well as a holder in the form of a small, open-topped plastic box with double-sided tape on its bottom. The holder can be adhered to a surface, and a foam prism can be inserted into the open top of the holder and used in the same manner as the Aspen holder described above.

[0003] The Aspen and Quosina holders are relatively low-cost items that can be discarded after use, avoiding the need for sterilization, and can be inexpensively replaced with new holders for subsequent use. However, foam prisms, once adhered to a surgical drape, are not always stable; the double-sided tape may not adhere well to the drape fabric, and / or the drape may bend / bend, tilting the prism (and any syringes contained therein). Alternatively, the prism can be glued to a surgical tray or other surface, but this tends to leave adhesive residue on the surface, requiring additional post-operative cleaning. Furthermore, because the prism holds the instrument so that it protrudes vertically from the top of the prism, long, thin instruments (e.g., syringes) remain vulnerable to accidental bumps (and dislodging from the prism) during manipulation. Summary of the Invention

[0004] The present invention relates to an instrument holder that is intended to at least partially solve the aforementioned problems. In order to provide the reader with a basic understanding of some of the advantageous features of the present invention, the following is a summary of a preferred version of the instrument holder, and to assist the reader in understanding, reference is made to the accompanying drawings (which are briefly discussed in the "Brief Description of the Drawings" section below of this document). It should be understood that the following description is merely a summary, and that more details regarding the preferred version may be found in the Detailed Description elsewhere herein. And, the claims at the end of this document define various versions of the invention to which exclusive rights are reserved.

[0005] 1a-1b, an exemplary preferred version of the present invention includes an instrument holder 100 that includes a rigid, durable base block 10 having elongated projections 10p and a receiving block 20 formed of a soft, pierceable material and that can be pierced by the projections 10p (as shown in FIGS. 3b-3c). The instrument holder 100 further includes attachment means for removably and non-invasively attaching the base block 10 to a placement surface 200 (e.g., a tray or table surface in an operating room). (The term "non-invasive attachment" refers to attachment that does not damage the placement surface 200 or otherwise leave any noticeable adhesive or other residue on the placement surface 200. That is, the condition of the placement surface 200 after the base block 10 is removed is substantially the same as it was before the base block 10 was attached.) Here, the attachment means is provided by a mounting block 30 that is magnetically attracted to the base block 10 (or vice versa). The mounting block 30 allows the base block 10 to be attached to the mounting surface 200 in the manner shown in FIGS. 3a-3b. The mounting block 30 is positioned on the opposite side of the mounting surface 200 from the base block 10, and the base block and mounting blocks 10 and 30 are magnetically coupled to each other with respect to the mounting surface 200. With the base block 10 attached to the mounting surface 200 in this manner, an instrument can be pierced through the receiving block 20 and held in a usable state. This is shown in FIGS. 3d-3f. Here, a cap 300c for a hypodermic syringe 300 is inserted into the receiving block 20 (FIG. 3e). The syringe 300 is then withdrawn from the cap 300c (FIG. 3f), allowing the user to unsheath the needle 300n of the syringe 300 with one hand, leaving the cap 300c readily available for resheathing the needle 300n (and holding the syringe 300 as in FIG. 3e) when use of the syringe 300 is complete.The receiving block 20 can be removed from the base block 10 after a single use and discarded, or alternatively, can undergo multiple uses before being removed and discarded, and a new receiving block 20 can be attached to the base block 10 for subsequent use.

[0006] The protrusions 10p preferably extend from the upper base block surface 10u and preferably have longitudinal axes that are at least approximately parallel. The protrusions 10p are preferably located adjacent to the side base block surfaces 10s, with each protrusion 10p located closer to the edge of the upper base block surface 10u than to any other protrusion 10p, so that when the receiving block 20 is penetrated centrally by an instrument (see, for example, FIGS. 3d-f), the protrusions 10p are unlikely to impede penetration (i.e., the instrument is not interfered with by the protrusions 10p in the receiving block 20). And, the protrusions 10p are preferably located adjacent to the side base block surfaces 10s, with each protrusion 10p located closer to the edge of the upper base block surface 10u than to any other protrusion 10p, so that when the receiving block 20 is penetrated centrally by an instrument (see, for example, FIGS. 3d-f), the protrusions 10p are unlikely to impede penetration (i.e., the instrument is not interfered with by the protrusions 10p in the receiving block 20). L The mounting means may include the above-mentioned mounting means. The mounting means may be attached to the lower base block surface 10 (as shown in FIG. 2). L The mounting means may take the form of a magnet or ferromagnetic material 10m on or within the lower base block surface 10 (and the mounting block 30 carries the cooperating magnetic or ferromagnetic material 30m). L This may take the form of one or more suction cups (as exemplified by FIG. 4 a) or sticky surfaces (e.g., silicone or other sticky gel pads as exemplified by FIG. 4 b) on the base block 10, allowing the base block 10 to be removably and non-invasively attached to the placement surface 200 without the use of a mounting block 30.

[0007] The receiving block 20 is preferably formed of a resiliently expandable material, i.e., the material can deform to accommodate the protrusions 10p and instruments 300 penetrating the receiving block 20, but tends to return to its original, unpenetrated configuration, thereby gripping any penetrating protrusions 10p / instruments 300 (such grip can be overcome with minimal effort by the user when withdrawing the receiving block 20 from the protrusions 10p or withdrawing an instrument from the receiving block 20). As will be described in more detail below, a resilient, flexible polymer foam is a preferred material for the receiving block 20. As best seen in FIG. 1b, the receiving block underside 20 L 1a-1b may have preformed protrusion openings 20p therein to facilitate entry by the protrusions 10p of the base block 10; such protrusion openings 20p are formed with a smaller diameter than the protrusions 10p so that they can expand around the protrusions 10p during insertion. One or more of the receiving block side surfaces 20s and / or the receiving block top surface 20u may similarly have one or more preformed instrument openings 20i therein. Such protrusions and / or instrument openings 20p and 20i are preferably defined by or otherwise located at the intersections of valleys 20v formed in the receiving block 20 (these valleys 20v are preferably simple cuts / slits formed in the receiving block 20; the cuts / slits of the valleys 20v in FIGS. 1a-1b extend completely through the receiving block 20 and open on opposite sides of the receiving block 20). Such valleys 20v better accommodate larger instruments (e.g., larger diameter veterinary hypodermic syringes 300) as well as better accommodate imprecise (off-center) insertion of protrusions 10p / instrument 300.

[0008] The mounting block 30 (if provided) is attached to the lower base block surface 10 L The upper mounting block surface 30u and the lower mounting block surface 30 L, and side mounting block surfaces 30s therebetween. The handle 30h is attached to the lower mounting block surface 30 (as in the exemplary instrument holder 100 shown in the drawings). L The mounting block 30 may be provided on the top or on the side mounting block surfaces 30s so that the mounting block 30 can be more easily pulled from the placement surface 200 to which it is magnetically attracted (via the base blocks 10 on the opposite sides of the placement surface 200).

[0009] Further potential advantages, features, and objects of the present invention will become apparent from the remainder of this document taken in conjunction with the associated drawings. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Expanding on the above discussion, the receiving block 20 may have any shape suitable for receiving the instrument(s) it is intended to receive. (More generally, throughout this document, the term "block" refers to a body having any shape. Thus, for example, the receiving block 20 need not be in the shape of a rectangular prism, but could have a dome-like or other shape.) The material of the receiving block 20 is preferably resiliently expandable, i.e., capable of deforming to accommodate an instrument penetrating the receiving block 20, but tending to return to its original, unpenetrated shape, thereby gripping any penetrating instrument. If no opening is formed in the receiving block 20, it is also preferably made of a material soft enough to allow the insertion of an instrument biased into the receiving block 20. Typical materials for the receiving block 20 are closed-cell or open-cell foams made from ethylene vinyl acetate (EVA), polyethylene, polyurethane, polyester, polyether, or vinyl nitrile. Natural or synthetic sponges or soft solid materials, such as silicone rubber, paraffin, or other soft polymeric materials, may alternatively be used.

[0012] As shown, the instrument openings 20i extend completely through the depth of the receiving block 20 from one of the side receiving block surfaces 20s to the opposite receiving block surface 20s, with valleys 20v extending radially outward from the periphery of the instrument openings 20i, which valleys 20v also extend completely through the depth of the receiving block 20. The protrusion openings 20p (arranged in the receiving block 20 in a position where they can receive the protrusions 10p of the base block 10) similarly extend completely through the depth of the receiving block 20 from the upper receiving block surface 20u to the lower receiving block surface 20s. L 1 and 2, extending completely through the thickness of the receiving block 20, each having a radially extending valley 20v that extends completely through the thickness of the receiving block 20. The valleys 20v shown in the figures are formed by cuts / slits in the receiving block 20 having negligible width between the sides of the valleys 20v, but may be formed with a larger width (but preferably less than the diameter of any instrument / protrusion 10p to be inserted into the corresponding opening). The valleys 20v advantageously allow for easier insertion and removal of instruments / protrusions 10p having diameters larger than the diameter of the opening, and further, better accommodate the insertion of instruments / protrusions 10p that are not precisely centered with the opening, with the valleys 20v tending to bias an inserted instrument / protrusion 10p toward its openings 20i and 20p.

[0013] In alternative versions of receiving block 20, openings 20i and / or 20p and / or valleys 20v need not extend completely through receiving block 20. Furthermore, openings 20i and / or 20p may be provided in different numbers and / or in different arrangements (e.g., one or more instrument openings 20i may be provided in all of side receiving block surfaces 20s and / or in top receiving block surface 20u). Openings 20i and / or 20p need not include valleys 20v, or openings 20i and / or 20p may be defined simply by the intersection of valleys 20v. The openings 20i and / or 20p do not need to be defined as circular holes, and need not be provided at all if the protrusion 10p and / or tool 300 are simply biased into the surface of the receiving block 20 (in which case the protrusion 10p and / or tool 300 form the openings 20i and / or 20p as the protrusion 10p and / or tool 300 penetrates the receiving block 20).

[0014] Unlike the resiliently compressible (and expandable) receiving block 20, the base block 10 and its protrusions 10p are preferably rigid and formed of a durable material that can be easily sterilized, such as metal (e.g., stainless steel) or hard plastic, or a combination thereof (e.g., a plastic base block 10 with protruding metal protrusions 10p). Each protrusion 10p preferably has a width-to-depth ratio of approximately 1 (width and depth measured along an axis perpendicular to the longitudinal axis of the protrusion 10p) and / or a circularity (isometric quotient) of approximately 1, with a blunt tip to prevent injury if a user's hand / arm accidentally comes into contact with the tip. Each protrusion 10p preferably has a length / height of at least one-third the height of the receiving block 20, so that the protrusion 10p extends at least one-third of the way through the receiving block 20 impinging on it, although shorter lengths can be used as long as the protrusion 10p securely holds the receiving block 20 during use. The length / height of the protrusion 10p may be greater than that of the receiving block 20 onto which it is to be pierced, so that after the receiving block 20 is placed on the protrusion 20p, the protrusion 10p may protrude from the upper surface 20u of the receiving block, but it is preferable that the length / height of the protrusion 10p is equal to or less than the height of the receiving block 20.

[0015] More or fewer protrusions 10p can be provided on the base block 10. Only a single protrusion 10p may be provided on the base block 10, in which case the single protrusion 10p preferably has a width-to-depth ratio greater than 1 or a circularity (isometric quotient) less than 1. This is because a more circular cross-section of the single protrusion 10p more easily allows the receiving block 20 to rotate around the protrusion 10p during use. Thus, for example, the single protrusion 10p may be formed as a flange / plate or with a trefoil or cross-shaped cross-section. Multiple sets of protrusions 10p may be provided on the base block 10, each set adapted to receive its own receiving block 20, thereby allowing the base block 10 to accommodate multiple receiving blocks 20.

[0016] The protrusions 10p preferably extend from the upper base block surface 10u, but may alternatively or additionally be provided on one or more side base block surfaces 10. Regardless of the surface(s) of the base block 10 on which the protrusions 10p are provided, any receiving block(s) 20 to be received on the protrusions 10p preferably have their instrument opening(s) 20i oriented at least approximately perpendicular to the protrusions 10p against which the receiving blocks 20 are to be thrust, thereby better preventing subsequent disengagement of the receiving blocks 20 from the protrusions 10p during removal and / or insertion of instruments. In the arrangement shown in the figures, the instrument openings 20i are oriented at least approximately perpendicular to the lower base block surface 10 L (and therefore the placement surface 200 to which the base block 10 is to be attached), it is also advantageous to orient any inserted instrument parallel to the placement surface 200, reducing the chance of the instrument being inadvertently struck by the user's arm during operation (as may occur if the instrument extended more perpendicularly from the receiving block 20).

[0017] As previously mentioned, the base block 10 includes attachment means for removably and non-invasively attaching to the placement surface 200, such as any one or more of a magnet (as in 10m of FIG. 2), a suction cup (as in 10c of FIG. 4a), or a sticky surface (e.g., a silicone or other sticky gel pad as in 10g of FIG. 4b) attached to the lower base block surface 10. L While these structures are preferred attachment means, alternatives are possible, such as clips, clamps, or other mechanisms that close near the edge of the mounting surface 200, or that provide sufficient mass to the base block 10 and / or the lower base block surface 10. L By providing a sufficient area for the base block 10 to be mounted on the mounting surface 200, the base block 10 is effectively immobile during conventional use after placement on the mounting surface 200. By way of example, the base block 10 may have a mass of at least 2 kg and / or may have plates extending 10 cm or more outward from the side base block surfaces 10s.L (lower base block surface 10 L (possibly bearing elastomer or other non-slip pads). If base block 10 is to use magnetic mounting means, magnets (preferably strong magnets, e.g., rare earth magnets) can be provided on or within base block 10 to provide an attractive force to mounting blocks 30 that include magnets 30m of opposite polarity, or that otherwise include ferromagnetic material (i.e., material that is attracted to magnets) (e.g., as seen in FIG. 2, 10m, the lower base block surface 10 L (as an insert into the mounting block 30). Conversely, the mounting block 30 may have the magnet mounted on or within it, and the base block 10 comprises a ferromagnetic material. If the mounting surface 200 is ferromagnetic, the magnetic base block 10 may simply be attached directly to the mounting surface 200 without the use of the mounting block 30. Alternatively, if the mounting surface 200 is not ferromagnetic, a ferromagnetic plate may be glued to the mounting surface 200 to enable the attraction of the magnetic base block 10 to the mounting surface 200.

[0018] The mounting block 30, if provided, is preferably formed of a rigid, durable, and sterilizable material (as is the base block 10). The mounting block 30 preferably includes a handle 30h thereon to allow it to be more easily grasped by a user's hand and pulled from the placement surface 200. The illustrated handle 30h is attached to the lower mounting block surface 30. L In the illustrated embodiment, the handle 30h takes the form of a knob protruding from the side mounting block surface 30s, however, the handle 30h may alternatively or additionally be located on the side mounting block surface 30s and may take alternative forms, such as one or more protruding loops or elongated members, or protrusions (e.g., ridges) or depressions (e.g., grooves) defined on one or more side mounting block surfaces 30s.

[0019] The present invention encompasses the mounting block and receiving block arrangements described herein, as well as the receiving block alone (e.g., when sold as a consumable / disposable item for use with a separately provided base block), and also the base block alone (e.g., when sold as a durable item for use with a separately provided consumable / disposable receiving block).

[0020] Throughout this document, various terms referring to orientations and positions, e.g., "upper" (as in "upper receiving block surface") and "lower" (as in "lower receiving block surface"), should be considered relative terms rather than absolute terms. In other words, it should be understood that (for example) a referenced upper receiving block surface may actually be located on the side or bottom of the holder, depending on the overall orientation of the holder. Thus, such terms should be considered terms of convenience rather than of limitation.

[0021] Throughout this document, when measurements or other values ​​are modified by terms such as "approximately," "about," "almost," "roughly," etc., this can be considered to refer to a 10% variation from the stated value. Thus, as an example, "approximately perpendicular" and "approximately parallel" can be understood to mean within 9 degrees (i.e., 10% of 90 degrees) of perpendicular and parallel, respectively.

[0022] The present invention is not intended to be limited to the preferred versions of the invention described above, but rather is intended to be limited only by the claims set forth below. Contains No term(s) expressed in any claim shall be construed pursuant to U.S. § 112(f) unless the terms "means for" or "step for" are expressly used in such terminology.
