Description

PERISTALTIC PUMP ASSEMBLY AND REGULATOR THEREFOR
BACKGROUND
[0001] The present invention relates generally to peristaltic pump assemblies and, more particularly, to a peristaltic pump assembly and a regulator therefore.

[0002] Peristaltic pumps are often used to deliver fluid in a very controlled manner such as, for example, the intravenous delivery of medicine to a patient.
The peristaltic pump may generally include a pump body having a cassette removable attached thereto, and a tube supported by the cassette. A fluid (e.g., medicine) flows through the tube, generally by increments, as the tube is occluded against a race formed in the cassette. Occlusion of the tube may occur by a compression force applied to the tube by the rollers driven by a motorized drive shaft.

[0003] In some instances, small variations in the size and/or location of at least come components in the pump assembly may cause at least some variation in the compression force. This may also lead to at least some variation in the load applied to the pump motor. One way of controlling at least some of these variations is to maintain a substantially constant force applied to the tube by the rollers. This may be accomplished by coupling each roller with a spring, where the spring forces the roller against the tube via a relatively constant force.
SUMMARY

[0004] As disclosed herein, a peristaltic pump assembly includes a pump body and a cassette removably attached thereto, wherein the cassette includes a race configured to provide a compression surface for a tube supported by the cassette. A roller assembly is operatively connected to the pump body to rotate about an axis of rotation, wherein the roller assembly includes a plurality of rollers configured to apply a force to the tube, thereby compressing the tube against the race. The peristaltic pump assembly further includes a regulator la disposed in the pump body and operatively connected to the cassette. The regulator includes an L-shaped slide member having a first leg and a second leg substantially perpendicular to the first leg, wherein the first leg and the second leg are non-rotatable relative to each other; a pre-loading member, wherein the second leg of the slide member is mounted on the pre-loading member to permit the slide member to move as a unit in a linear direction relative to the pre-loading member; a mounting pin carried by the first leg for rotatably mounting the cassette to the slide member, the mounting pin defining an axis of rotation of the cassette, wherein the mounting pin moves with the slide member in the linear direction; a spring operatively connected to the second leg to apply a force in a direction orthogonal to the axis of rotation defined by the mounting pin.

[0007] Fig. 2 is a perspective, plan view of the pump body shown in Fig.

DETAILED DESCRIPTION

[0010] Embodiment(s) of the peristaltic pump assembly including the regulator as disclosed herein advantageously allow a substantially constant force to be applied on a tube, which is supported by a cassette, and by a plurality of rollers of the pump assembly. The substantially constant force applied to the tube allows the tube to be occluded by the rollers in a relatively consistent manner, thereby improving the operating performance of the pump assembly at least with regard to, e.g., the accuracy of the amount of fluid to be delivered by the pump assembly to a patient, the amount of power consumed by the pump assembly, the operating life of the cassette, the operating life of a roller mechanism employed by the pump assembly, and the operating life of a pump motor also employed by the pump assembly. The substantially constant force may also reduce the noise level of the pump assembly when the pump assembly is operating.

[0011] Other advantages of the pump assembly including the regulator include simplification of the pump assembly process, whereby adjustment(s) and/or calibration(s) of the regulator may not be necessary once the pump assembly has been assembled. Also, variations in the cassette, as well as the size and/or location of the cassette and/or other components within the pump assembly, may generally have little effect on the substantially constant force applied to the tube by the plurality of rollers.

[0012] As defined herein, the term "substantially constant force" refers to a force having a measured value remaining within the 10% of a median value.
Non-limiting examples of "substantially constant forces," as referred to herein, include a substantially constant compression force and a substantially constant spring force.

[0013] With reference to Figs. 1 and 2, the peristaltic pump assembly 10 generally includes a pump body 12 and a cassette 14 removably attached thereto by an attachment member 15. In an illustrative example, the peristaltic pump assembly 10 will be described herein as including a mounting pin as the attachment member 15 (though it is to be understood that various alternate examples of the attachment member 15 may be used). Details of an examply of a method of removably attaching the cassette 14 to the pump body 12 via the mounting pin 15 may be found in U.S. Patent No. 7,934,912, which is commonly owned by the Assignee of the present disclosure. It is to be understood, however, that other suitable means and/or methods for removably attaching the cassette 14 to the pump body 12 may also be considered as being within the spirit and scope of the present disclosure.

[0014] The pump body 12 further includes a cassette receiving portion 16 having a partial cavity 20 defined by a floor (not shown) and two opposing walls 22, 24. A roller assembly 26 (e.g., a roller mechanism) is housed within the cavity 20 and operatively connected to the pump body 12. Roller assembly 26 includes a plurality of satellite rollers 28 arranged in a planetary configuration.
The rollers 28 rotate as an assembly, as well as individually, in response to rotational forces imparted thereto by a motorized drive shaft (not shown). The motorized drive shaft may be operated by a pump motor (not shown), which are both operatively connected to the pump body 12.

[0015] An exploded view of the cassette 14 is generally depicted in Fig.
3, where the cassette 14 includes a cassette body 30 and a cover 32 disposed thereon. The cassette 14 may be disposable, as desired. The cassette body 30 includes an inlet 34 formed in an end 36 thereof and an outlet 38 formed in another end 40 thereof. The inlet 34 and outlet 38 are configured to receive first and second ends of a tube 42 (shown in Fig. 1), thereby supporting the tube 42 in the cassette 14.

[0016] In a non-limiting example, the tube 42, which is also disposable, may be classified as substantially flexible so that the tube may be compressed and/or occluded by the rollers 28, as will be described further below. In an embodiment, the tube 42 is made of a polymeric material. Non-limiting examples of suitable polymeric materials include silicones, AUTOPRENETm (an opaque thermoplastic rubber with high wear resistance derived from SANTOPRENETm, commercially available from Advanced Elastomer Systems, a subsidiary of ExxonMobil Chemical located in Houston, TX), VITONTm (a black fluoroelastomer with resistance to concentrated acids, solvents, ozone, radiation and temperatures up to 200 C with good chemical compatibility, commercially available from DuPont Performance Elastomers located in Wilmington, Delaware), TYGON TM (good chemical resistance with a clear finish, commercially available from Saint-Gobain Performance Plastics Corporation located in Akron, Ohio), PROTHANE IITm (a transparent, blue, polyester, polyurethane tubing with good chemical resistance, commercially available from Randolph Austin Company located in Manchaca, Texas), and/or the like, and/or combinations thereof. The inner diameter of the tube 42 may be selected based on the desirable flow rates and the desirable viscosities of the fluid that will flow therethrough.

[0017] The cassette 14 further includes a race 44 formed therein and configured to provide a compression surface for the tube 42. It is to be understood that during operation of the pump, the rollers 28 apply a compression force against the tube 42 in response to rotational movement of the rollers 28. The compression force compresses the tube 42 against the race 44 to thereby substantially occlude the tube 42. This compression force is a predetermined force controlled by a regulator 46 of the pump assembly 10. As such, in response to the rotational movement of the rollers, portions of the flexible tube 42 that are in contact with the rollers 28 compress or are otherwise occluded against a wall of the cassette 14. As a result, fluid is temporarily retained in the tube 42 between the occluded points. In this manner, fluid is urged through the tube 42 via peristaltic wave action. Details of an example of a suitable cassette 14 may be found in U.S. Patent No. 8,062,008, which is commonly owned by the Assignee of the present disclosure.

[0018] As depicted in Fig. 4, the regulator 46 is disposed in the pump body 12 and is operatively connected to the cassette 14. It is to be understood, however, that the regulator 46 may otherwise be disposed in the peristaltic pump assembly 10, e.g. adjacent to the pump body 12 and/or as part of the pumping mechanism assembly. In an embodiment, the regulator 46 includes a slide member 48 having the mounting pin 15 connected thereto. The slide member 48 may be any suitable support member capable of moving along a substantially linear path of length L. In an embodiment, and as shown in Fig.
4, a window 52 is formed in the pump body 12. At least a portion of the slide member 48 extends through the window 52. The window 52 is configured to allow the slide member 48 (including the mounting pin 15 connected thereto) to linearly slide or otherwise move a distance along a length L in response to changes/variations in the pump assembly 10 or components thereof (e.g., variations in the wall thickness of the tube 42 at the compression area of the race 44, wear of the rollers 28, thermal length variations of components, manufacturing variations, etc.).

5a [0019] Movement of the slide member 48 (e.g., in the window 52) may be restricted by the regulator 46 via a spring 50 also provided therewith and operatively connected to the slide member 48. The spring 50 may be operatively situated such that the spring 50 compresses along substantially the same linear direction as the slide member 48. In an embodiment, the spring 50 may be selected from those having a spring constant ranging from about 3 lbf/in (0.525 N/mm) to about 5 lbdin (0.875 N/mm). Non-limiting examples of suitable springs include helical springs, clock springs, torsion springs, compression springs, extension springs, leaf springs, elastomeric bodies, and/or the like, and/or combinations thereof.

[0020] In an embodiment, a predetermined pre-load may be applied to the spring 50 using a pre-loading member 54 operatively connected thereto. As shown in Fig. 4, the pre-loading member 54 may be a shoulder bolt extending through the spring 50 and through a bore (not shown) formed in the slide member 48. It is to be understood that other devices may suitably be used as the pre-loading member 54, non-limiting examples of which include screws, pegs, pins, shafts, and/or the like, and/or combinations thereof. In a non-limiting example, the predetermined pre-load applied to the spring 50 ranges from about 1.5 lbf (7 N) to about 3 lbf (14 N).

[0021] The regulator 46 is generally configured to regulate and/or control the compression force applied to the tube 42 by the rollers 28 so that the compression force is a substantially constant force. To accomplish this, the regulator 46 restricts the amount of the compression force applied to the tube within a predetermined boundary or range. The predetermined boundary or range may be determined, e.g., based on the spring constant of the spring 50 and the distance that the slide member 48 travels in order to compress the spring 50. Restricting the amount of the compression force may be accomplished by allowing the mounting pin 15 (which is connected to the slide member 48) to move in response to changes and/or variations in the peristaltic pump assembly 10. In a non-limiting example, such changes and/or variations include variations in the individual components of, or the assembly 10 as a whole (as mentioned above), e.g., when the assembly 10 is infusing a fluid to a patient.

[0022] In an embodiment, before the cassette 14 is mounted to the pump body 12, the slide member 48 is slightly pre-loaded (e.g., a pre-load of about lbf to about 2.5 lbf) via compression of the spring 50. Upon mounting the cassette 14, the slide member 48 moves in the y-direction from its pre-load position, and the spring 50 compresses slightly further beyond the pre-load force. The tube 42 is substantially occluded under the force applied by the spring 50. During operation of the roller mechanism, as the rollers 28 rotate, slight variations and/or changes in the size of the tube 42, various components of the cassette 14, the rollers 28, and/or the like are controlled by the slide member 48 by moving the slide member 48, against the spring 50, in the y-direction along the substantially linear path of length L. It is to be understood that movement of the slide member 48 is relatively small in order to sufficiently control the changes in the pump assembly 10 components, etc., and to maintain a substantially constant compression force applied to the tube 42 by the rollers 28. In a non-limiting example, the slide member 48 moves a length L ranging from about 0.25 mm to about 0.5 mm.

[0023] Although the pump assembly 10 has been described including the regulator 46 operatively connected to the mounting pin 15, it is to be understood that the regulator 46 may otherwise be operatively connected to a pump body retaining feature 56 (shown in Fig. 2) disposed or otherwise formed in the pump body 12. In an embodiment, the pump body retaining feature 56 is configured to matingly engage a cassette retaining feature 58 (shown in Fig. 3) formed on the cassette body 30, thereby securing the cassette 14 to the pump body 12 when assembled therewith.

[0024] Also disclosed herein is a method of regulating the predetermined force applied to the tube 42 by a plurality of rollers 28 in the peristaltic pump assembly 10, thereby compressing the tube 42. The method is accomplished by providing pump assembly 10 including the regulator 46, and regulating the predetermined force applied to the tube 42.

[0025] It is to be understood that the term "connect/connected" or the like is broadly defined herein to encompass a variety of divergent connecting arrangements and assembly techniques. These arrangements and techniques include, but are not limited to (1) the direct connection between one component and another component with no intervening components therebetween; and (2) the connection of one component and another component with one or more components therebetween, provided that the one component being "connected to" the other component is somehow operatively coupled to the other component (notwithstanding the presence of one or more additional components therebetween).

[0026] While several embodiments have been described in detail, it will be apparent to those skilled in the art that the disclosed embodiments may be modified. Therefore, the foregoing description is to be considered exemplary rather than limiting.
