The inlet ports (44, 46) are configured to receive flexible tube portions (20a, 20b) that traverse through the tube passages in the clamp. Each tube passage (54, 56) includes at least one open area (66) and at least one occluding portion (56) to establish and terminate flow therethrough. The clamp (14) is pivotable from a prime position to an intermittent flow position and from an intermittent flow position to a continuous flow position, to effect varying flow conditions.

Description

CONTAINER WITH PIPE CLAMP WITH PIVOT 0 TURN FIELD OF THE INVENTION The invention relates to a chamber and a tube clamp for multiple flow adjustment for use in a fluid delivery device. More particularly, the invention relates to a tube clamp for multiple flow adjustment with pivot that mounts to, and is movable around, a chamber in a fluid delivery device.

BACKGROUND OF THE INVENTION Fluid administration devices, such as parenteral administration sets are widely used in the medical field. Typically, an administration set includes one or more devices and an interconnect pipe assembly. The devices and the piping assembly may include one or more injection orifices to provide, for example, medicaments such as antibiotics, within the fluid stream. The whole is connected to a REF .: 30960 source or fluid supply container such as a bag full of fluid. In one arrangement, the administration set includes a test chamber which is particularly adapted to contain and provide a given volume of fluid to the patient.

One of the uses for such administration set is the intravenous administration of a solution to the patient. Often, a patient is fed intravenously with a constant flow of saline, dextrose or other solution from the supply container. Such administration sets can also be used to provide an added and measured amount of drugs or nutrient elements in a solution to the patient if desired.

In an arrangement for providing a precise amount of fluid to a patient, the solution supply container or container is connected, to the flow communication, with an intermediate probe chamber by means of an upper or first portion of the administration set. A lower or second portion of the assembly extends from the test chamber towards the patient. The administration set typically includes one or more clamps, and connectors along the length thereof.

Referring to Figure 1, a test tube 1 of the prior art is illustrated. The test chamber 1 holds the fluid in an internal chamber 2. A filling tube 3 allows the injection of fluid from a container (not shown) from the supply source fluid source within the inner chamber 2, and a venting tube 4 which vents the internal chamber 2 to the atmosphere, and the outer end of the vent tube includes a filter 5. A lower administration tube 6 allows administration from the internal chamber 2 to a patient. The fluid can be injected into the inner chamber 2 through an injection hole 7.

A clamp 8 of the pipe on the filling tube 3 and a clamp 9 of the pipe on the vent pipe 4 are manipulated to adjust the flow or fluid mode in or out of the internal chamber 2. The users of the Test tube 1 camera will probably want to place the test tube camera; either within a first mode; and then selecting between an intermittent administration or an "intermittent" mode; or a continuous mode. In the priming mode, a desired quantity of fluid from the source container (not shown) is added to the internal chamber 2. The clamps 8 and 9 of the pipe are manipulated so that both tubes 3 and 4 are respectively opened . A clamp 11 of the lower pipeline is opened to fill or load the rest of the administration pipe 6 and regulate the flow. The source fluid flows into the chamber 2 and displaces the flow of air through the vent tube 4 and the filter 5. When the desired amount flows into the internal chamber 2, clinicians decide the mode, intermittent or continuous, with which they wish to operate the device below.

In intermittent mode, after the test chamber has been filled to the desired level as a portion of a first mode, the clamp 8 is closed and the clamp 9 remains open. The air flows through the vent tube 4 into the internal chamber 2 to prevent the formation of a vacuum in the chamber which can impede flow to the patient. When the desired amount of fluid is administered to the patient, the lower clamp 11 closes. The process can be repeated as often as desired to give an intermittent administration of the fluid to the patient.

In continuous mode, the flow flows continuously through chamber 2 and into the patient. The clamp 8 on the filling tube 3 opens and prepares for fluid to flow from the source container (not shown) into the internal chamber 2 and then exit through the delivery tube 6. The clamp 9 on the tube of venting 4 closes to prevent the escape of air and a subsequent flooding of the internal chamber 3.

As one can see from the above description, provided for each of the first modes, the continuous mode and the intermittent mode require a single arrangement of the pipe clamps 8, and 9 for opening or closing the corresponding pipe. It must be remembered that these arrangements are problematic for the provider.

In addition, there is nothing to indicate to the user which of the modes is the test chamber 1, except for the arrangements of the clamps of the pipe.

Accordingly, there is a need to provide an intermediate chamber which a user can place in various flow modes without the user needing to remember the unique arrangements of the clamps of the individual pipe. A related need is to have a way to indicate to the user when the appropriate flow mode is performed.

BRIEF DESCRIPTION OF THE INVENTION A clamp for flow regulation tubing is used with an intermediate chamber in a parenteral fluid delivery device. In an example of a preferred embodiment, the camera is a test chamber. The chamber has a cap and a main body portion that forms an internal chamber. The cap has at least one and preferably two holes and a first pivot element.

Preferably the holes are separated from each other and with respect to the first pivot element. The clamp includes a body portion having a second pivot element that can be coupled with the first pivot member on the cap. Preferably the coupling between the clamp and the cap forms a hinge. The body additionally comprises at least one and preferably a plurality of elongated tube receiving passages separating from the second pivot member. The clamp is configured such that each passage is at a different radial distance from the second pivot member. Preferably each of these passages are configured as pipe clamps for pipe segments which extend through the passages.

In a preferred embodiment, the first passage defines a broad cross-sectional area that varies therethrough as it has large, outer, first and second cross-sectional areas connected to each other and adjacent to a first occlusion portion, similar to a channel, narrow, between the wide areas. Preferably, the first and second cross sectional areas, broad, are substantially identical with each other. The clamp is placed on the cap with first and second pivot elements coupled to each other to form the hinge with the first passage overlying the cap hole and a segment of pipe extends from the hole and passes through the passage.

In one embodiment, the clamp includes a second elongated passage, spaced from the first passage, and the cap of the chamber includes a second hole with the second passage overlying the second hole with a tube extending from the second hole and passing through the second port. second passage.

In such an embodiment, the second passage includes a broad, elongated cross-sectional area adjacent to a second narrow channel-like occlusion portion. In a preferred arrangement, the open area and the occlusion portion of the first passage correspond to the open portion of the second passage, and the other open portion of the first passage corresponds to the second occlusion portion of the second passage. This open-occluded passage arrangement allows the measuring chamber to be placed in at least two and preferably three different flow modes, namely, a priming mode, an intermittent mode, and a continuous flow mode.

In a more preferred embodiment, the clamp is mounted on a test chamber cap and is included within the parenteral administration set. The administration set includes one more pipe lengths connecting the chamber with a container storing a solution such as an intravenous bag. The test chamber of the present invention has the flow adjusting clamp mounted thereon, and a portion of the tubing assembly extending downwardly from the chamber to a patient feeding device.

In another embodiment, the clamp may include markings, which when aligned with a marker on a chamber cap, indicate to the user that the clamp is positioned in an appropriate position with the desired flow shape. Other aspects and advantages of the present invention will be apparent from the following detailed description, the accompanying drawings, and the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES While the present invention is susceptible to modalities in various forms, it is shown in the drawings and a preferred embodiment will be described below taking into account that the present description is to be considered as an exemplification of the invention and is not intended to limit the invention to the specific embodiment illustrated.

Reference now to the figures and in particular to Figure 2, there is shown a preferred embodiment of a parenteral fluid solution or administration set 10 having a measuring chamber as a test chamber 12 including a control clamp 14 flow in accordance with the principles of the present invention. Administration set 10, an example of such is a BURETROL® administration set, available from Baxter International Inc. of Illinois, USA, empowered with the present application, is typically used to provide a given amount of a fluid to a patient . The fluid can be delivered intravenously, intraperitoneally, or in other ways that are recognized by those skilled in the art.

In one arrangement, the administration set 10 is connected to a fluid source container (not shown), and includes a spigot 16 for connecting the administration set 10 to the container; a measuring chamber 12; several extensions of pipe 20; and one or more holes or sites 22 for injection. The assembly 10 further includes a connecting element 24 and a roller clamp 18 to allow connection of the assembly 10 to a patient feeding device such as a catheter (not shown). Those skilled in the art will recognize that the particular components and arrangements of the components in an administration set 10 can vary widely and that the administration set 10 can include, or be assembled without, certain aforementioned components.

Reference now to Figures 2 and 3, the measurement chamber 12 includes a portion 26 of the main body and an upper cap 28. The chamber 12 may include a lower cap 30 which is attached to a leaky chamber 32 (Figure 1) . Typically, the body 26 of the chamber is formed of a transparent material, and includes calibration marks 34 therein so that the amount of fluid in the chamber 12 can be accurately measured. Thus, the amount of food can be controlled. of fluid from chamber 12 to the patient.

Referring to Figures 4 and 5, the upper cap 28 includes a first pivot member 36 which is preferably an injection orifice 37, and at least one, preferably two, inlet ports 38, 40. As shown in FIG. better appreciated in Figure 5, the first pivot member 36 is positioned eccentrically in the cap 28. In a preferred embodiment, the intake holes 38, 40 are formed as openings in the upper cap 28. The upper cap 28 fits within of the body 26 of the chamber and can be secured thereto by methods known in the art.

The first and second intake ports 38, 40 will be separated relative to one another relative to the first pivot member 36. The intake port 38 is connected to a flexible pipe 20a as used in the administration set 10, and the vent hole 40 is connected to a flexible pipe 20b. The pipes 20a and 20b are received in receptacles in each of the first and second holes 44,46, respectively, and can be fixedly connected to the internal walls of the receptacles 44 and 46. The holes 38, 40 provide flow communication between the interior of the chamber 12 and the pipe 20 connected thereto.

The flow control clamp 14 includes a body portion 50 having a second element, for example a passageway 52, which can be engaged with the first element 36 on the cap 28 so that the cap 28 engages in some way. with the clamp 14 but the clamp 14 is movable relative to the cap 28. Preferably, the clamp 14 is mounted on the cap 28 to form a hinge 53 so as to allow the clamp 14 to rotate about the first element 36 located on the cap 28. The hinge 53 can be provided by a rotatable adaptation slidable between the clamp 14 and an annular recess formed on the injection orifice 37.

The clamp 14 includes at least one, and preferably a plurality of, as in example two, passages 54 and 56 receivers of the elongated flexible tube formed therein. The passages 54 and 56 correspond to the pipes 20a and 20b, respectively, connected to the holes 38 and 40, in the cap 28. The tube passages 54, 56 are spaced in relative relation to each other and to the hinge 53. preference the passages are configured as slots.

Preferably, when the clamp 14 fits the cap 28 the passages 54, 56 extend radially from the second element 52 so that the first and second passages 54, 56 cover the intake ports 38,40 of the cap. As seen in Figures 4 and 5, the passages 54, 56 have an arched shape so that the clamp 14 rotates around the cap 28, the two passages 54, 56 continue to cover the holes 38, 40.

Refer now to Figure 4, the tube passages 54, 56 have open areas of varying cross section along at least a portion of their extension. A first preferred passageway 54 has a bone shape of the dog that includes two open end areas 60, 62 of relatively large cross section that taper inwardly toward a relatively narrow, channel-like occlusion or connection portion 64 extending between these. Preferably, the open areas 60, 62 are configured in a similar manner. It is recognized by those skilled in the art that when a tube segment extends through any of the widely open end portions 60, 62, the tube 20a is preferably not clogged or not occluded, and the flow through this It can be given at a relatively high speed. Vice versa, when a tube segment extends through the relatively narrow passage 64 that connects the open end areas 60, 62, the tube 20a is compressed so that the tube is tightened or occluded and the flow through it will be likewise reduced to a substantially lower or stopped flow rate.

The tightening is a slight compression of the pipe 20a or 20b, and the ranges from a light compression to a total occlusion of the pipe.

A second preferred passage 56 in the bracket 14 includes an elongated wide area portion 66 and a narrower and relatively shorter channel-like occlusion or compression portion 68. The portions 66, 68, open and occlusion respectively, operate in the same manner as those described above for the first passage 54. That is, when the tube 20b is placed in the widely open area 66, it is not squeezed and the flow through this can occur at a relatively high speed, while when the tube 20 is placed in the tight area 68, the tube 20 is compressed so that it is occluded which, in turn, reduces or stops the flow through this.

As seen in Figure 4, the first and second passages 54,56 are placed with their respective broad and narrow portions in a predetermined relationship with one another. This brings as a particular result, the desired flow characteristics in the tubes 20a and 20b when the clamp 14 is oriented in different positions relative to the chamber 12. It will be noted that, in the position indicated by the line A in Figure 3, the open areas 60 and 66 of the first and second passages 54 and 56, correspond to one another. Movement in a counter-clockwise direction from line AA, on line BB, of the squeezed portion 64 of first passage 54 corresponds to an open area 66 of a second passage 56. Again, a movement in counter clockwise from line B to the position indicated on line CC, again the other open area 62 of first passage 54 corresponds to the tight area 68 of second passage 56.

Referring to Figures 3 and 4, the clamp 14 may include a signaling to indicate to the user what position the clamp is in, relative to the camera 12. for a particular flow condition. The clamp 14 may include one or preferably a multiple of unique markings or markings 70 which when aligned with a marker 72 indicate to the user the position of the clamp.

In addition, to facilitate manipulation of the clamp 14 and the outer edge 80 can be configured with one or more slits 82 or other means to facilitate clamping or movement of the clamp.

The operation of an exemplary test chamber 12 is now described and with respect to the use of the flow control clamp 14 for the realization of several, desired flow modes, in and out of the chamber 12 through the tubes 20a and 20b and the corresponding holes 38, 40. Especially, the positions for the flow conditions and the respective clamp 14 are: (1) filling or priming the chamber 12 from a source vessel of the associated solution, this is referred to as the priming position and corresponds to the line AA in the figure 4; (2) the administration of a predetermined amount of a solution to a patient from chamber 12, this is referred to as the intermittent position and corresponds to line B-B of Figure 4; and (3) continuing the flow of a solution from the solution container through the chamber 12 to the patient, which is referred to as the continuous flow position and corresponds to the line C-C.

To prime the chamber 12, the clamp 14 is rotated so that the passage portions 60, 66 extend along the line AA (Figure 4) and are placed in alignment with the intake ports 38, 40. A signage 70 labeled "primed" can be aligned with the marker 72 (Figure 3) to indicate to the user that the clamp 14 is in the priming position. For purposes of the present description, the first passage 54, which is the passage closest to the hinge 53, has the filling tube 20a, which is connected to the source container (not shown), which passes through it. The second tube passage 56, which is the outermost passage, has the tube 20b of the tube assembly 20 passing through it and the tube 20b which is used to vent air from the chamber 12. The vent tube 20b can use a filter 73.

In the prime position, both are open, the fill tube 20a and the vent pipe 20b (eg, associated with the holes 38, 40). The solution flows from the source vessel (not shown) into the chamber 12, and further allows the air to vent from the chamber 12 through the vent tube 20b. When a desired amount of fluid flows into the chamber 12 the user rotates the clamp 14 to the position indicated on line BB, the intermittent position, to stop the flow of fluid from the source container into the chamber 12. In this position , additional fluid is prevented from entering chamber 12, and the patient can only be given the fluid in chamber 12. A signage 70 labeled "intermittent" can be aligned with marker 72 to indicate to the user that the clamp is in an intermittent position. When the lower clamp 18 is opened, air flows through the vent tube 20b and the orifice 40, and this allows the contents of the chamber 12 to flow freely from the chamber 12 towards the patient without pulling a vacuum inside the chamber 12. In this way, only a predetermined amount of solution can be administered to the patient, without the need to continuously monitor a source container.

By rotating the clamp 14 to the position of continuous flow, in which the portions of the passages 54, 56 are indicated with the line CC covering the intake orifices 38, 40, a continuous flow of the solution to the patient. A signage 70 labeled "continuous" can be aligned with the marker 72 to indicate to the user that the clamp 14 is in the continuous flow position. In this position, the fluid from the solution container flows into the chamber 12 through the open filling tube 20a. However, the air vent tube 20b is tightened or occluded, which prevents air from leaving the chamber 12 through the vent tube 20b and thereby flooding the chamber 12. A lower pipe clamp 18 (Figure 2), is then typically used to create a flow contour of a solution from the drip chamber 12 to the patient. The present flow control clamp 14 provides a number of advantages superior to those of the known flow control clamp devices. First, as is readily appreciated in the figures, the present clamp 14 is attached to the cap 28 of the chamber 12. Thus, it is no longer necessary to provide or locate a separate flow control device or clamp.

In addition, as will be appreciated by those skilled in the art, the present device allows manual positioning or positioning of the clamp to perform such desired flow modes with a movement. That is, once the supply and vent tubes have been placed inside the chamber cap 28, the clamp 14 can be rotated between the continuous flow, intermittent and priming positions with one hand, by rotating the Clamp 14 simply. Thus, a desired flow condition can be placed quickly and easily with minimal effort, only by the rotation of the flow control clamp 14.

In addition, the clamp 14 occludes or opens the filling tube 20a the venting tube 20b for the arrangements necessary for the continuous, intermittent priming modes thereby relieving the user of having to remember the unique arrangement of the individual pipe clamps. which are found in the devices of the prior art.

In addition, there are small limitations for the various arrangements of the different configurations of slots, numbers of slots pipes for which the present invention can be applied. as you can see changing these elements can provide multiple flow modes which can be applied to other types of cameras as well as in other applications.

From the foregoing it will be seen that numerous modifications variations can be made without departing from the true spirit scope of the novel concepts of the present invention. This is so that it is understood that there is no attempt or deduction of limitation with respect to the specific modalities illustrated. The description attempts to cover all appended claims of which all modifications fall within the scope of the claims.

For example, the clamp can be attached or operably attached to the container by directly joining the container or joining an intermediate piece which is attached to the container or one or more of a set of intermediate pieces, one or more of which They are attached to the container.

It is noted that in relation to this date, the best method known to the applicant, to put into practice the aforementioned invention is that it is clear from the manufacture of the objects to which it refers.

Having described the invention as above, property is claimed as contained in the following:
