Description

[Technical field]

[0001] SUMMARY OF THE DISCLOSURE The present invention relates to a pinch-type clamp designed for use in clamping or occluding plastic tubing, such as intravenous tubing. [Background technology]

[0002] A pinch clamp is a well-known type of one-piece plastic clamp that is used to block plastic tubing, such as intravenous tubing, etc. Pinch clamps generally comprise a smooth, hard plastic material that is resilient and capable of controlled bending to permit engagement and disengagement of the clamping surfaces.

[0003] The molding or extrusion process of manufacturing pinch clamps typically results in clamps having sharp edges that can scratch or otherwise irritate the patient on whom the clamp is used. Additionally, the hard and smooth nature of the clamp's plastic makes it difficult to grasp and manipulate the clamp during use, especially when the clamp becomes wet.

[0004] In some cases, the hard and smooth characteristics of the clamp's plastic may even result in the unintentional release of the clamp when a shear force is applied to the interlocked clamp arms. For example, and with reference to FIG. 1, a prior art pinch clamp 1 is shown in a closed or clamped configuration under shear force. The prior art pinch clamp 1 generally includes a first arm 2 having a lip 3 configured to selectively engage a terminal end 5 of a second arm 4. When the terminal end 5 is received by the lip 3, the clamp 1 is engaged in a clamping configuration. When a shear force 6 is applied to either the first arm 2 or the second arm 4, the lip 3 and terminal end 5 may prematurely release, releasing the clamping pressure.

[0005] Thus, while methods and devices for clamping sections of tubing using pinch clamps currently exist, challenges remain. Accordingly, features of the present invention address and overcome these challenges. Summary of the Invention [Means for solving the problem]

[0006] The present invention relates to a pinch-type clamp designed for use in clamping or occluding plastic tubing, such as intravenous tubing. The pinch clamp of the present invention addresses and overcomes various difficulties known to exist in prior art pinch clamps. For example, some embodiments of the present invention include a soft material applied to various surfaces of the pinch clamp to 1) prevent abrasion or irritation to the patient, 2) increase friction between the pinch clamp and a user manipulating the pinch clamp, 3) increase friction between engaged surfaces of the pinch clamp to prevent premature or unintended release of the clamp, and 4) increase friction between the outer surface of the tube and the clamping surface of the clamp.

[0007] Some embodiments of the invention further include a dynamic clamping surface or interface that results in a positive displacement of fluid within the tube during the pinch clamp engagement process. In particular, some embodiments of the invention include a planar, elongated first clamping surface configured to contact and support a first side of the tube. The pinch clamp further includes an angled, elongated second clamping surface, whereby the second clamping surface includes a first end spaced a first distance from the first clamping surface, and the second clamping surface further includes a second end spaced a second distance from the first clamping surface, the second distance being greater than the first distance.

[0008] When the pinch clamp is closed, the first end of the second clamping surface contacts the second side of the tube and closes off a portion of the tube located between the first clamping surface and the first end of the second clamping surface. As further closing motion occurs, the angled surface of the second clamping surface progressively closes or clamps the tube along the length of the first clamping surface, thereby displacing fluid within the tube volumetrically from the interface between the first and second clamping surfaces. When the pinch clamp is fully engaged, the second end of the second clamping surface also comes into contact with the second side of the tube such that the tube is closed or clamped along the entire length of the first and second clamping surfaces.

In some cases, the second clamping surface includes a first end and a second end, the first end spaced a first distance from the first clamping surface and the second end spaced a second distance from the first clamping surface, the second distance being greater than the first distance.

In some cases, the second hinge allows the terminal end of the second arm to pivot toward the hinge interconnecting the first arm and the second arm.In some cases, the first arm or the second arm includes extensions positioned on opposing sides of the arm, and the other of the first arm or the second arm includes an inner extension that is inserted between the opposing extensions when the pinch clamp device is engaged. In some cases, the first arm includes raised surfaces positioned on each side of the first clamping surface, and the second clamping surface is inserted between the raised surfaces when the pinch clamp device is engaged.

[0016] In some cases, the hinge forms an oval shaped opening between the hinge and the first and second clamping surfaces. In some cases, the outer edges of the first and second arms are rounded. In some cases, the terminal end of the second arm forms an interface surface having an end that projects outwardly beyond the rounded outer edge of the second arm.

[0022] The present invention relates to a pinch-type clamp designed for use in clamping or occluding plastic tubing, such as intravenous tubing. The pinch clamp of the present invention addresses and overcomes various difficulties known to exist in prior art pinch clamps. For example, some embodiments of the present invention include a soft material applied to various surfaces of the pinch clamp to 1) prevent abrasion or irritation to the patient, 2) increase friction between the pinch clamp and a user manipulating the pinch clamp, 3) increase friction between engaged surfaces of the pinch clamp to prevent premature or unintended release of the clamp, and 4) increase friction between the outer surface of the tube and the clamping surface of the clamp.

[0023] Some embodiments of the invention further include a dynamic clamping surface or interface that results in a positive displacement of fluid within the tube during the pinch clamp engagement process. In particular, some embodiments of the invention include a planar, elongated first clamping surface configured to contact and support a first side of the tube. The pinch clamp further includes an angled, elongated second clamping surface, whereby the second clamping surface includes a first end spaced a first distance from the first clamping surface, and the second clamping surface further includes a second end spaced a second distance from the first clamping surface, the second distance being greater than the first distance.

[0024] When the pinch clamp is closed, the first end of the second clamping surface contacts the second side of the tube and closes a portion of the tube located between the first clamping surface and the first end of the second clamping surface. As further closing motion occurs, the angled surface of the second clamping surface progressively closes or clamps the tube along the length of the first clamping surface, thereby displacing fluid within the tube volumetrically from the interface between the first and second clamping surfaces. When the pinch clamp is fully engaged, the second end of the second clamping surface also comes into contact with the second side of the tube such that the tube is closed or clamped along the entire length of the first and second clamping surfaces.

[0025] 2A illustrates a perspective top and side view of a pinch clamp 10. The pinch clamp 10 generally includes a first arm 12 having a first end including a lip 14 forming a ledge 15. In some cases, the lip 14 includes a plurality of parallel ledges or ridges. The first arm 12 further includes a second end including a first clamping surface 16. In some cases, the first clamping surface 16 includes a raised surface having a width approximately equal to the width of the clamp 10. In some cases, the first clamping surface 16 is planar or generally flat. In other cases, the first clamping surface 16 is angled, rounded, pointed, ridged, grooved, or any combination thereof.

[0026] The pinch clamp 10 further includes a second arm 20 having a first end including a terminal end 24. The terminal end 24 is generally configured to engage with the lip 14 to secure the clamp 10 in the engaged configuration. In some cases, the terminal end 24 includes a blunt, square end. In some embodiments, the terminal end 24 includes a wedge-shaped or tapered shape such that the terminal end 24 tapers outwardly to a tip or pointed edge. The terminal end 24 further includes an interface surface 22 that is configured to matingly engage with the ledge 15 of the lip 14 to hold the clamp 10 in the engaged configuration.

[0027] In some embodiments, the second arm 20 includes a second end having a second clamping surface 26. The second clamping surface 26 is generally positioned opposite the first clamping surface 16, as is common in pinch clamps. In some cases, the second clamping surface 26 is tapered such that in the released configuration, a first end of the clamping surface 26 is spaced a first distance from the clamping surface 16 and a second end of the clamping surface 26 is spaced a second distance from the clamping surface 16, the second distance being greater than the first distance. In one embodiment, the second end of the clamping surface 26 is closest to the first end 24 of the second arm 20, and the first end of the clamping surface 26 is proximate the closed end 32 of the clamp 10.

[0028] The second ends of the first arm 12 and the second arm 20 are interconnected via a hinge 30. In some cases, the hinge 30 includes a rounded extension of the second ends of the first arm 12 and the second arm 20. The hinge 30 is configured to position the first arm 12 on the opposite side of the second arm 20. In some cases, the hinge 30 includes a relaxed position (as shown in FIG. 2) and a tensioned position (not shown). In the relaxed position, the hinge 30 positions the first arm 12 and the second arm 20 to provide a gap or space between the first clamping surface 16 and the second clamping surface 26. The relaxed position of the hinge 30 further maintains a gap or space between the terminal end 24 and the lip 14. In some cases, the hinge 30 further includes a window or opening 34 through which the tube is passed. The first arm 12 further includes a window or opening 36 that is generally aligned with the window 34 and is configured to receive a tube.

[0029] In some embodiments, the contact or exterior surface 26 of the second arm 20 further includes a grip feature 28. The grip feature 28 is generally provided to increase friction between a user's thumb or fingers and the pinch clamp 10 during use. In some cases, the grip feature 28 includes a plurality of parallel ridges or raised features. In some embodiments, the grip feature 28 includes texturing or other surface treatments intended to increase friction. In some cases, the grip feature 28 further provides visual and / or tactile references indicating how and where a user should grip the clamp 10.

[0030] Some embodiments of the present invention further include a soft polymeric material 40 applied to various surfaces of the pinch clamp 10. As used herein, the term "soft polymeric material" is understood to include any material that may be applied to or added to a plastic material suitable for use in manufacturing the pinch clamp 10, the soft polymeric material comprising a Shore A durometer hardness less than the plastic material from which the pinch clamp is constructed. For example, in some embodiments, the soft polymeric material comprises a Shore A durometer hardness of approximately 15 to 100, approximately 20 to 80, approximately 30 to 70, approximately 40 to 60, approximately 45 to 55, or approximately 50. In some cases, the soft polymeric material comprises a Shore A durometer hardness less than 15. In some cases, the soft polymeric material comprises a Shore A durometer hardness greater than 100.

[0031] Non-limiting examples of soft polymeric materials include thermoplastic elastomers, such as thermoplastic rubbers, copolymers, and the like, or physical mixtures of polymers, such as plastics and rubbers, crosslinked polymers, styrene block copolymers, polyolefin blends, elastomeric alloys, thermoplastic polyurethanes, thermoplastic copolyesters, thermoplastic polyamides, or combinations thereof.

[0032] For example, in some cases, the soft polymer material is applied as a thin coating to the hard or semi-rigid material of the pinch clamp. In some cases, the soft polymer material piece is first created by a known process, such as extrusion or injection molding. The polymer piece is then applied to one or more surfaces of the pinch clamp, such as by adhesive, mechanical interference, or interlocking features or surfaces. In some cases, one or more surfaces of the hard or semi-rigid material of the pinch clamp are removed and replaced by a polymer piece to provide a final profile and shape for the pinch clamp. In some embodiments, the pinch clamp is provided in a two-shot molding process, where a first injection unit is provided to mold the hard or semi-rigid material of the clamp and a second injection unit is provided to apply the soft polymer material at strategic locations. In some cases, one or more surfaces of the hard or semi-rigid material of the pinch clamp are removed and replaced by a polymer material or piece to soften one or more contact surfaces. In some cases, one or more surfaces of the rigid or semi-rigid material of the pinch clamp are removed and replaced with a polymeric material or piece to increase friction between two or more surfaces of the clamp, or between one or more surfaces of the clamp and a section of tubing that is inserted into the clamp.

[0033] In some cases, the soft polymeric material 40 is applied to various surfaces of the pinch clamp 10 to soften various surfaces of the pinch clamp 10 that may otherwise scratch or irritate the patient's skin. For example, in one embodiment, the soft polymeric material 40 is applied to edge or side surfaces 50 of the pinch clamp 10. In one embodiment, the soft polymeric material 40 is applied to orthogonal surfaces 52 of the pinch clamp 10. Additionally, in one embodiment, the soft polymeric material 40 is applied to contact surfaces, it being understood that "contact surfaces" includes any exposed surfaces that may come into contact with a patient during use. In some cases, the soft polymeric material 40 is applied to all exterior surfaces of the pinch clamp 10.

[0034] In some cases, the soft polymer material 40 is applied to various surfaces to increase friction. For example, in one embodiment, the soft polymer material 40 is applied to the grip feature 28 of the pinch clamp 10, thereby increasing friction between a user's thumb or fingers and the pinch clamp 10. In one embodiment, the soft polymer material 40 is applied to at least one of the first clamping surface 16 and the second clamping surface 26, thereby increasing friction between the clamping surfaces and a tube secured therebetween.

[0035] In one embodiment, a soft polymeric material 40 is applied to at least one of the lip 14 and the terminal end 24 to increase friction therebetween. As discussed above in connection with the prior art clamp 1 of FIG. 1, a hard plastic interface between the lip 3 and the terminal end 5 allows for distortion of the first arm 2 and the second arm 4 when a shear force 6 is applied to the clamp 1. This can result in premature or unintended release of the clamp 1. In contrast, the soft polymeric material 40 interface between the lip 15 and the terminal end 24 increases the friction between these surfaces, thereby preventing unintended release. A detailed view of these surfaces is shown in FIG. 2B.

[0036] In some embodiments, the surface of at least one of the lip 15 and the terminal end 24 further includes a mechanical feature or surface 25 configured to further increase lateral or axial friction at the interface surface 22, as shown in Figures 3A-3C. For example, in one embodiment, the interface surface 22 has a mechanical feature 25 including a plurality of interlocking grooves. In some cases, the mechanical feature 25 provides alignment between the first arm 14 and the second arm 20. In some cases, the mechanical feature 25 includes a micro-feature, such as a texture. In some embodiments, the mechanical feature 25 includes a micro-feature that is parallel, perpendicular, or perpendicular and parallel to the direction of the tube threaded through the clamp 10. In some cases, the mechanical feature 25 is formed in the hard polymeric material of the clamp 10 and then coated or covered by the soft polymeric material 40. In other cases, the mechanical feature 25 is provided directly in the soft polymeric material 40.

[0037] 4A-4D, some embodiments of the present invention include a dynamic clamping surface or interface 55 that results in positive displacement of fluid 60 into a clamped tube 70. Positive displacement of fluid 60 may be desirable when the fluid 60 includes a medication that would remain in the tube 70 except for being advanced into the patient via positive displacement.

[0038] 4A, pinch clamp 10 is shown in a released configuration whereby first side 72 of tube 70 is supported entirely on elongated first clamping surface 16 of first arm 12. Additionally, first end 27 of second clamping surface 26 is positioned adjacent to or in light contact with second side 74 of tube 70.

[0039] In some embodiments, the first clamping surface 16 is generally planar and elongated such that the surface 16 supports a length of the tube 70. In contrast, the second clamping surface 26 is angled such that the first end 27 is positioned below or closer to the first clamping surface 16 than the location of the second end 29. As such, the second clamping surface tapers outwardly or upwardly from the first end 27 to the second end 29, or from the proximal end to the distal end of the second clamping surface 26.

[0040] The tube 70 is not compressed or occluded when the pinch clamp 10 is in the released configuration. Rather, the tube 70 is free to move between the first clamping surface 16 and the second clamping surface 26. In some embodiments, the first clamping surface 16 and the second clamping surface 26 further include a soft polymeric material (not shown) that increases friction between the tube 70 and the clamping surfaces, preventing the pinch clamp 10 from sliding freely along the length of the tube 70. Rather, the pinch clamp 10 must be manually adjusted by the user to a desired position on the tube 70, after which the clamp 10 maintains its position due to the friction between the soft polymeric material and the outer surface of the tube 70.

[0041] In some embodiments, a soft polymeric material (not shown) further provides a cushioning function between the hard plastic material of pinch clamp 10 and the soft plastic material of tube 70. In some cases, this cushioning function allows for complete closure of tube 70 while preventing severe kinking that could weaken the tube structure. In some cases, this cushioning function improves tube recovery when pinch clamp 10 is released.

[0042] 4B, the pinch clamp 10 is moved from a released configuration to a partially engaged configuration when the second arm 20 is moved in a downward direction 80 such that the tube 70 is pinched between the first end 27 of the second clamping surface 26 and the proximal end of the first clamping surface 16. Thus, a portion of the tube 70 located between the first clamping surface 16 and the second clamping surface 26 is occluded, and a portion of this section of the tube 70 is unoccluded.

[0043] As first arm 20 is further advanced in downward direction 80, the distance between second clamping surface 26 and the remaining surfaces of first clamping surface 16 is gradually reduced as second end 29 descends toward first clamping surface 16, as shown in FIG. 4C. This gradual closure pushes or positively displaces fluid 60 out from between the clamped surfaces, thereby advancing fluid 60 through a distal section of tube 70. In some cases, the displaced fluid 60 is infused into a patient via an intravenous catheter connected to tube 70.

[0044] The first arm 20 is further advanced in the downward direction 80 until the distal end 24 is received by the lip 14, thereby fully engaging the pinch clamp 10, as previously discussed. Upon full engagement, the tube 70 is fully clamped between the second end 29 of the second clamping surface 26 and the first clamping surface 16, as shown in FIG. 4D. In some cases, the first end 27 and the second end 29 are approximately equal distances from the first clamping surface 16 when the pinch clamp 10 is fully engaged. Following full engagement of the pinch clamp 10, the volumetric transfer of the fluid 60 is completed.

[0045] In some embodiments, the second arm 20 bends or pivots about the contact point between the first end 27 and the first clamping surface 16 such that the clamping pressure or contact between the second clamping surface 26 and the tube 70 is applied in a linear manner. In some embodiments, the hinge 30 is configured to flex laterally to accommodate, facilitating the linear application of compressive force between the first clamping surface 16 and the second clamping surface 26.

[0046] In some embodiments, at least one of the first clamping surface 16 and the second clamping surface 26 further includes a proximal end that includes or is constructed of a rigid or semi-rigid material, as shown in FIG. 5, and further includes a distal end that includes or is constructed of a soft polymeric material 40. This embodiment has the benefit of providing a robust primary or proximal clamping interface while having a softer distal clamping interface to compress the interior volume of the tube while preventing over-compression of the tube over the entire length of the clamping surface. In some cases, the rigid or semi-rigid proximal end material further reduces friction between the pinch clamp and the tube 70 when in the released configuration, thereby allowing easy movement of the clamp 10 along the length of the tube 70.

[0047] In some cases, and prior to clamping, the tube 70 may exit the pinch clamp 10 laterally between the first arm 12 and the second arm 20. Accordingly, some embodiments of the present invention further provide one or more extensions 100 to hold the tube within the pinch clamp 10, as shown in Figures 6A-6C. In some cases, a portion of the outer edge surface of the first arm 12 is extended upward toward the second arm 20, as shown in Figure 6A, to provide a wall or extension 100. In some cases, a portion of the outer edge surface of the second arm 20 is extended downward toward the first arm 12, as shown in Figure 6B, to provide a wall or extension 100. In some embodiments, the pinch clamp 10 includes two or more extensions 100. In one embodiment, the pinch clamp 10 includes a first extension 100 on a first side of the second arm 20 and a second extension 100 on a second side of the second arm 20, the second side being opposite the first side. In one embodiment, the pinch clamp 10 includes first and second extensions 100 on opposite sides of the first arm 12. Additionally, in some embodiments, the pinch clamp 10 includes first and second extensions 100 on opposite sides of the first arm 12 and further includes first and second extensions 100 on opposite sides of the second arm 20, the extensions overlapping, abutting, or filling the distance between each other when the clamp 10 is in an engaged configuration.

[0048] The extension 100 is configured to at least partially close the gap between the first arm 12 and the second arm 20 when in an engaged or disengaged configuration. In some cases, the extension 100 is a thin fin or plate of a rigid or semi-rigid material. In some cases, the extension 100 is a thin fin or plate of a soft polymeric material 40. In some cases, the extension 100 is a thin fin or plate of a rigid or semi-rigid material onto which the soft polymeric material 40 is applied. Now referring to FIG. 6C, in some embodiments, the outward edge of the first clamping surface 16 further includes one or more extensions 100 extending upwardly toward the second clamping surface 26. Additionally, the outer edge of the second clamping surface 26 includes one or more recesses or cutouts 110 configured to receive the one or more extensions 100 when the pinch clamp 10 is engaged. The interaction between the extensions 100 and the recesses 110 holds the tube 70 within the clamping surfaces when the clamp 10 is engaged. In some cases, a portion of the rigid or semi-rigid material of the clamp 10 is removed and replaced with a soft polymeric material 40 to provide one or more of the first and second clamping surfaces 16, 26, the extensions 100, and the recesses 110.

[0049] 7A-12 illustrate several different variations of pinch clamps in accordance with one or more embodiments of the present invention. Each of these pinch clamps includes the same general structure as pinch clamp 10. Accordingly, many of the components of each pinch clamp will not be described redundantly. However, like numbers will be used to refer to these like structures. Also, while the figures show various specific embodiments that include one or more variations, these variations may be used in addition to, or in place of, features of any of the other described embodiments of the pinch clamp.

[0050] 7A-7D illustrate an embodiment of a pinch clamp 700 that is similar to pinch clamp 10, but that employs a nesting component 701 to prevent lateral release of the second arm 20 from the first arm 12. In other words, the nesting component 701 can prevent relative movement between the first arm 12 and the second arm 20 in a direction substantially perpendicular to the longitudinal axis of the tube to which the pinch clamp 700 may be coupled. As a result, by including the nesting component 701, the pinch clamp 700 (or other similar embodiments of pinch clamps that include a nesting component) will tend to release only when the clinician intentionally applies a downward / outward force to the terminal end of the first arm 12.

[0051] As better shown in FIG. 7B, which shows the nesting component 701 in isolation, the nesting component 701 includes opposing sidewalls 701a that are coupled together via an interconnect 701b. The width / diameter of the interconnect 701b can be configured to allow the interconnect to sit within an opening 712 formed between the hinge and the clamping surface, while the length of the interconnect 701b can be configured such that the sidewall 701a is positioned just outside of the outer surfaces of the first arm 12 and the second arm 20. The size of the sidewall 701a (i.e., the amount that the sidewall 701a extends in any direction away from the interconnect 701b) can be sufficient to cause the sidewall to overlap the first arm 12 and the second arm 20, thereby limiting lateral movement of the two arms.

[0052] The interconnect 701b can include an opening 701c that generally aligns with the opening 34 to accommodate a tube that can extend through the pinch clamp 700. One or both of the inner surfaces of the sidewalls 701a can also include a raised feature 701d that acts to limit rotation of the nesting component 701 relative to the pinch clamp 700. In some embodiments, the sidewalls 701a can have a size sufficient to cause the raised feature 701d to be positioned on the opposite side of the clamping surface from the interconnect 701b. For example, FIG. 7D illustrates how the raised feature 701d can be positioned to cause the feature to contact the inner surface of the first arm 12 or the second arm 20 when the nesting component 701 is rotated. In this manner, raised feature 701d minimizes the chance that opening 701c may kink or otherwise block the tube.

[0053] FIG. 7C shows pinch clamp 700 without nesting component 701, and FIG. 7D illustrates a cross-sectional side view of pinch clamp 700 containing nesting component 701, and FIGS. 7C and 7D illustrate how pinch clamp 700 (or other similar pinch clamps) can include clamping surfaces that provide positive displacement. As shown, first clamping surface 16 and second clamping surface 26 include protrusions 710 and 711, respectively. In these figures, protrusions 710 and 711 are shown at the left or proximal ends of the clamping surfaces. Protrusions 710 and 711 function in a similar manner to the dynamic clamping surfaces shown in FIGS. 4A-4D. Notably, when pinch clamp 700 is engaged, protrusions 710 and 711 will contact the tube before the remainder of first clamping surface 16 and second clamping surface 26. Thus, when pinch clamp 700 becomes fully engaged, fluid in the tube will be pushed in a distal direction (or in a rightward direction in FIG. 7D).

[0054] 8A and 8B illustrate another embodiment of a pinch clamp 800, which is similar to pinch clamp 10. However, in pinch clamp 800, first clamping surface 16 is formed as a recessed surface positioned between raised surface 801a and raised surface 801b. Thus, when pinch clamp 800 is engaged, second clamping surface 26 is inserted between raised surface 801a and raised surface 801b and contacts first clamping surface 16. In this manner, pinch clamp 800 provides multiple points of compression on the tube. More specifically, raised surface 801a and raised surface 801b can provide compression on the tube in the distal and proximal directions, respectively. This "arc" of compression can enhance closure of the tube and minimize the possibility that the tube will not be fully closed when pinch clamp 800 is engaged. Also, due to the respective angles between second clamping surface 26 and raised surface 801b, some volume transfer can occur when the tube is closed.

[0055] 8A and 8B also show that the pinch clamp 800 can include extensions 802a and 802b. In these figures, the extensions 802a and 802b are shown extending downward from the second arm. However, the extensions 802a and 802b can equally extend upward from the first arm. In some embodiments, as shown in FIG. 8B for example, the extensions 802a and 802b can include a rounded interconnect 802c. The rounded interconnect 802c can generally conform to the shape of the tube such that the tube is tightly contained between the extensions 802a and 802b when the pinch clamp 800 is engaged. This tight containment can act to prevent lateral movement between the first and second arms of the pinch clamp 800. More specifically, contact between extension 802a or extension 802b and the tube resists lateral movement of the second arm relative to the first arm such that the second arm cannot be easily moved laterally to the point of releasing it from the first arm.

[0056] 9 illustrates an embodiment of a pinch clamp 900 that employs a different configuration for the terminal end of the second arm 20. In contrast to the pinch clamp embodiments described above, the pinch clamp 900 is configured such that the second arm is released from the first arm by applying a force to the second arm that is generally in a proximal direction 910.

[0057] As shown, the second arm 20 includes a hinge 901 towards its distal end. The terminal end 902 of the second arm 20 extends upwardly and proximally away from the interface surface 22. As with the previously described embodiment, the interface surface 22 is inserted under the ledge 15 and engages the pinch clamp. However, to release the pinch clamp 900, rather than applying a force on the lip 14 in a downward / distal direction, a force in a proximal direction 910 can be applied to the terminal end 902. Alternatively, any of the other embodiments of the pinch clamp described herein can be configured as shown in FIG. 9. Also, the pinch clamp 900 can be configured to include any of the volume transfer features and / or nesting components as described above.

[0058] 10A-10C illustrate another embodiment of a pinch clamp 1000. The pinch clamp 1000 includes protrusions 1003a and 1003b extending upward from a first arm, and protrusion 1004 extending downward from a second arm. Protrusion 1004 may be configured to be inserted between protrusions 1003a and 1003b, and thus function to close the tube in a manner similar to that of pinch clamp 800. However, as best seen in FIG. 10C, in some embodiments, protrusion 1004 may have a length that is insufficient to cause protrusion 1004 to contact the first arm. Alternatively, in some embodiments, protrusions 1003a and 1003b may extend downward from the second arm, while protrusion 1004 may extend upward from the first arm. Additionally, the pinch clamp 1000 may be equally configured to include any of the other types of clamping surfaces described herein.

[0059] The pinch clamp 1000 can also include interlocking components that function to both limit the range of motion of the hinge between the first and second arms and to limit lateral movement between the first and second arms. These interlocking components include retaining components 1001a and 1001b and corresponding pivot tabs 1002a and 1002b. As shown, the retaining components 1001a and 1001b are positioned on opposite sides of the pinch clamp 1000. The pivot tabs 1002a and 1002b are also positioned on opposite sides of the pinch clamp 1000, but are offset slightly inward relative to the retaining components 1001a and 1001b to allow each of the pivot tabs 1002a and 1002b to be inserted into an opening formed in the corresponding retaining component. Pivot tab 1002a and pivot tab 1002b can each include an outwardly extending tip that interlocks with the retention component when the pivot tab is inserted into the opening, as shown in FIG. 10B.

[0060] Pivot tabs 1002a and 1002b may be configured to pivot inwardly, allowing them to bypass retaining components 1001a and 1001b as they move from the position shown in Fig. 10A to the position shown in Fig. 10B. Upon reaching the interlocked position shown in Fig. 10B, the outwardly extending tips of pivot tabs 1002a and 1002b will hold the pivot tabs in the interlocked position with no inward force on the pivot tabs. In other words, the interaction between the pivot tabs and the retaining components limits the amount that pinch clamp 1000 will open.

[0061] FIG. 10B represents the position of the pinch clamp 1000 when in the released state. To engage the pinch clamp 1000, a downward force can be applied to the second arm, causing the interface surface 22 to interlock with the ledge 15 in a manner similar to that described above with reference to the pinch clamp 10. FIG. 10C represents the position of the pinch clamp 1000 when in this engaged state. Releasing the interface surface 22 from the ledge 15 allows the pinch clamp 1000 to return to the released state as shown in FIG. 10B. As shown above, the interface between the pivot tabs 1002a and 1002b and the holding components 1001a and 1001b will then prevent the pinch clamp 1000 from opening beyond this position.

[0062] Additionally, the interface between pivot tabs 1002a and 1002b and retention components 1001a and 1001b will prevent lateral movement between the first and second arms. In this manner, the pinch clamp 1000 may be prevented from releasing due to the second arm moving laterally to free interface 22 from ledge 15.

[0063] 11 illustrates another embodiment of a pinch clamp 1100 that includes a feature to prevent lateral release of the pinch clamp. The pinch clamp 1100 includes an extension 1101a and an extension 1101b similar to the extension 100 described above. In some embodiments, the extensions 1101a and 1101b can be offset from one another, as shown in FIG. 11. Additionally, the pinch clamp 1100 can include an inner extension 1102 extending from an opposite arm from the extensions 1101a and 1101b (from the second arm in the example shown).

[0064] The inner extension 1102 may be positioned between the extensions 1101a and 1101b such that if the second arm were to be moved laterally relative to the first arm, the inner extension 1102 would contact one or both of the extensions 1101a and 1101b. This interaction between the extensions 1101a / 1101b and the inner extension 1102 may prevent lateral release of the pinch clamp 1100. The inner extension 1102 may be configured with a length that creates a gap between the inner extension 1102 and the first arm when the pinch clamp 1100 is engaged. In some embodiments, this gap may be small enough to cause the tube to be compressed. In such an embodiment, and due to the prior closure caused by the first clamping surface 16 and the second clamping surface 26, the inner extension 1102 may cause a positive displacement fluid transfer. Also, although not shown, in some embodiments, the inner extension 1102 can be configured to receive a tube in a manner similar to the rounded interconnect 802c. The pinch clamp 1100 can also include any of the other configurations of first and second clamping surfaces described herein.

[0065] FIG. 12 illustrates another embodiment of a pinch clamp 1200. The pinch clamp 1200 is configured in a manner similar to the pinch clamp 800 in that the first clamping surface 16 is formed as a recessed surface positioned between the raised surfaces 1201a and 1201b. The second clamping surface 26 is inserted between the raised surfaces 1201a and 1201b to provide an arc of compression along the tube. Also, because the second clamping surface 26 is positioned between the raised surfaces 1201a and 1201b when the pinch clamp 1200 is engaged, lateral release may be prevented. More specifically, if the second arm is moved laterally relative to the first arm, the second clamping surface 26 will contact one or both of the raised surfaces 1201a and 1201b and will prevent further lateral movement.

[0066] 13A and 13B illustrate another embodiment of a pinch clamp 1300. The pinch clamp 1300 can include clamping surfaces 16 and 26 and a hinge 30, which can be configured in any of the various ways described above. The hinge 30 can be constructed to form an oval shaped opening 1301 between the hinge 30 and the clamping surfaces 16 and 26. Additionally, as best seen in FIG. 13B, the pinch clamp 1300 can include rounded outer edges, which can enhance patient comfort.

[0067] 14A and 14B illustrate another embodiment of a pinch clamp 1400 that includes various lateral release prevention features. Similar to the pinch clamps previously described, the pinch clamp 1400 can include a clamping surface 16 and a clamping surface 26. Additionally, to prevent lateral release, the clamping surface 26 can include a recessed surface 1402a, while the clamping surface 16 can include lateral posts 1402b. As shown, the lateral posts 1402b can be formed on opposing sides of the clamping surface 16. The recessed surfaces 1402a can be sufficiently recessed to allow the clamping surface 26 to be inserted between the lateral posts 1402b. With the clamping surface 26 interposed between the lateral posts 1402b, the recessed surface 1402a contacts the lateral posts 1402b, thereby preventing lateral movement of the clamping surface 26 relative to the clamping surface 16. In some embodiments, including the one shown, the lateral posts 1402b are offset.

[0068] The pinch clamp 1400 can also include lateral release prevention features formed in the interface surface 22. For example, as shown in Figures 14A and 14B, the interface surface 22 can be formed with an outwardly facing recessed surface 1401a positioned between inwardly facing lateral protrusions 1401b positioned on opposite sides of the ledge 15. Thus, when the interface surface 22 is secured under the ledge 15, the lateral protrusions 1401b contact the recessed surface 1401a and prevent lateral movement. Although the pinch clamp 1400 is shown as including two types of lateral release prevention features, in other embodiments, the pinch clamp can include only one of these features.

[0069] As shown in Figures 13A and 13B, various embodiments of the pinch clamp can include rounded outer edges. However, by rounding the outer edges, the width of the interface surface 22 and ledge portion 15 can be reduced, thereby increasing the likelihood that the pinch clamp can be released laterally. To address such concerns, in some embodiments of pinch clamps that include rounded outer edges, particularly those that do not use another type of lateral release prevention feature, the interface surface 22 can be molded or otherwise formed to include ends 1501 that protrude beyond the outer surface of the remaining portion of the second arm 20, as shown in Figure 15. These protruding ends 1501 increase the width of the interface surface 22, thereby maximizing the amount of lateral displacement that would be required to release the pinch clamp. Also, in embodiments that use protruding ends 1501, the clamping surface can be configured to include a lateral release prevention feature similar to that described above with reference to Figures 14A and 14B.

[0070] FIG. 16A illustrates another embodiment of a pinch clamp 1600 that uses a separate component 1601 to prevent lateral release, while FIG. 16B shows the component 1601 alone. As shown, the pinch clamp 1600 can include a recessed section 1600a that is formed in the first arm 12 and positioned generally below and to the side of the clamping surface 16. The recessed section 1600a can be shaped and sized to accommodate the lateral release prevention component 1601 in a manner that causes an outer surface of the lateral release prevention component 1601 to substantially match an outer surface of the first arm 12. Thus, even though a separate component is used, there will be no sharp edges or transitions between the pinch clamp 1600 and the component 1601.

[0071] The component 1601 may have a U-shape formed by a bottom section 1601b and opposing arms 1601a extending upward from opposite ends of the bottom section 1601b. Each of the arms 1601a may include an inward protrusion 1601c positioned such that a bottom ledge of each protrusion 1601c is positioned on top of the first arm 12 when the bottom section 1601b is secured within the recessed section 1600a. The protrusions 1601c thus function to prevent the component 1601 from being separated from the pinch clamp 1600. Also, in some embodiments, the component 1601 may be secured to the arms 12 using an adhesive. The arms 1601a may be of sufficient length to ensure that they overlap the second arm 20, or at least overlap a portion of the clamping surface 26, thereby limiting the extent to which the arm 20 can be displaced laterally relative to the arm 12.

[0072] In addition to preventing lateral release of the pinch clamp, the various anti-lateral release features / components described herein also function to center the tube within the pinch clamp to ensure proper clamping. Thus, embodiments of the present invention ensure that the tube is properly clamped and will not become unintentionally released.

[0073] 17 illustrates another embodiment of a pinch clamp 1700 in which clamping surfaces 16 and 26 are configured to provide positive displacement fluid transfer. As shown, clamping surface 16 includes raised surfaces 1701a and 1701b, which are spaced apart to form recessed surface 1701c. Clamping surface 26 is similarly configured with raised surfaces 1702a and 1702b, which are spaced apart to form recessed surface 1702c. Raised surface 1702a and raised surface 1702b may be offset distally relative to raised surfaces 1701a and 1701b such that when pinch clamp 1700 is engaged, raised surface 1702b is inserted into recessed surface 1701c and raised surface 1701a is inserted into recessed surface 1702c.

[0074] Additionally, raised surface 1702b may be vertically offset relative to recessed surface 1702c such that raised surface 1702b is inserted into recessed surface 1702c before raised surface 1701a is inserted into recessed surface 1702c. This vertical offset will cause the tube to be clamped into recessed surface 1701c first, then into recessed surface 1702c. As a result, fluid contained in the portion of the tube that is distal to raised surface 1702b after raised surface 1702b is clamped (or distal to the left of raised surface 1702b with respect to the orientation shown in FIG. 17) will be pushed distally (or toward the patient) when raised surface 1701a is subsequently clamped.

[0075] The inclusion of raised surface 1702a and raised surface 1701b increases the length of the tube that will be clamped. For example, when raised surface 1701a is inserted into recessed surface 1702c, the tube will be clamped along recessed surface 1702c and raised surface 1702a. Raised surface 1702a can also be vertically offset relative to recessed surface 1702c, such that raised surface 1702a clamps the tube behind raised surface 1701a, thereby increasing the amount of volumetric fluid transfer. In FIG. 17, this vertical offset is achieved by angling clamping surface 26 relative to clamping surface 16 such that the distance between the two surfaces increases from the proximal to distal ends of the surfaces. However, the vertical offset can also be achieved in other ways, such as by angling clamping surface 16. This configuration of clamping surfaces 16 and clampings 26 may be used in conjunction with any of the lateral displacement features described above.

[0076] The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the present invention is therefore indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
