Definitions
- the present invention generally relates to peristaltic pumps and more particularly to precision peristaltic pumps, particularly suitable for the simultaneous removal and replacement of fluids in an eye cavity during ophthalmic surgery as, for example, for the removal of cataracts.
- Cataracts within the lens may be broken up by cutting apparatus or by ultrasonic apparatus and the fractured material aspirated, together with a quantity of aqueous fluid in the eye chamber.
- the aqueous fluid is simultaneously replaced in order to maintain a normal pressure in the eye.
- pressure may be controlled by a pressure regulation device, greater pressure stability may be assured through the use of a pump having minimal back pressure or pump pulsations.
- the present invention provides a peristaltic pump having significantly reduced pump pulsations and therefore particularly suitable for use in surgical procedures such as those hereinabove described.
- a peristaltic pump in accordance with the present invention generally includes a plurality of tube compression means for compressing and sealing a collapsible and resilient tube.
- Housing means is provided for guiding the collapsible and resilient tube to and from the tube compression means and means are provided for causing the plurality of tube com ⁇ pression means to successively contact, gradually compress and seal the compressible and resilient tube and thereafter gradually uncompress the tube in order to move a fluid through the tube in one direction without creating substantial fluid back pressure in the opposite direction.
- the plurality of tube compres ⁇ sion means may comprise a plurality of rollers and the means for causing the plurality of tube compression means to contact, compress and seal the tube comprises a pump arm, having an arcuate surface, and mounted to the housing means in a position enabling the rollers to contact, compress and seal the tube.
- the peristaltic pump in accordance with the present invention may further include assembly head means for supporting the plural- ity of rollers in a circular pattern about an assembly head axis with each roller having a rotation axis generally parallel to the assembly head axis.
- the arcuate surface is configured and the pump arm position with respect to the assembly head so that as the assembly head is rotated, each roller successively contacts the tube, gradually compresses and seals the tube during an approximate 45° rotation of the assembly head. Additionally, the arcuate surface is configured with the pump arm position with respect to the assembly head so that each roller successively releases a tube during a rotation of the assembly head about 45°.
- the arcuate surface is configured and the pump arm positioned with respect to the assembly head so that each roller maintains a sealing engagement with the tube during approximately a 45° rotation of the assembly head.
- each roller may include a specific circumferential surface thereon.
- each roller may have an inside diameter that is smaller than a roller diameter at each end of the roller, and this smaller diameter may be constant between end diameters on each roller, with the end diameters interconnected with the constant diameter by an arcuate surface.
- the present invention may also include a collapsible resilient tube which includes means for preventing movement of the tube itself through the housing means.
- the means for preventing movement of the tube may include at least one collar disposed on the tube having a diam ⁇ eter sufficient to prevent entry of the collar into the housing means.

- Figure 5a is a cross-section veiw of a prior art roller for a peristaltic pump showing incomplete sealing of a tube
- Figure 6 is a plot of vacuum pressure as a function of time for both a prior art peristaltic pump and a peristaltic pump in accordance with the present invention, showing in comparison a significant reduc ⁇ tion in back pressure during operation of the peristaltic pump made in accordance with the present invention operating at flow rate of about 10 ccs per minute
- Figure 7 is a plot similar to the plot shown in
- FIG. 6 showing the vacuum as a function of time for both prior art pumps and a pump in accordance with the present invention at a flow rate of about 40 ccs per minute.
- a peristaltic pump 10 in accordance with the present invention generally including an assembly head 26 which provides a means for supporting a plurality of rollers 28 with the latter providing compression means for compressing and sealing a collapsible and resil ⁇ ient tube 32 against an arcuate surface 34 on a pump arm 36.
- the pump arm 36 is pivotally mounted to a housing 40 by means of a pin 42 and washer 44 for enabling movement thereof to facilitate insertion and removal of the tube 32.
- Apertures 46 48 in the housing 40 enable the housing to provide means for guiding the collapsible and resilient tube 32 to and from the arcuate surface 34 and rollers 28.
- a spring 52 loaded latch 54 pivotally mounted to the pump arm 36 by a pin 55 enables locking of the pump arm 36 to the housing after insertion of the tube 32 through the apertures 46 and 48, and during opera ⁇ tion of the pump. This locking is enabled by the tongue 56 which snaps over a recess 58 in the housing 40, securing a front housing wall 60 between the tongue 56 and a rear portion 62 of the latch 54.
- the assembly head 26 is rotatably attached to the housing 40 by way of an axle 68 which passes through bearings 70, 72, a bore 76 in the housing 40 and a hub 78 and coupling 80.
- the axle 68 is retained in position by a clip 82 in a conventional manner along with a set screw 86.
- the pump arm 36 with arcuate surface 34 is positioned with respect to the assembly head rollers 28 to pro ⁇ vide a means for gradually compressing and sealing the collapsible and resilient tube 32 and thereafter grad- ually uncompressing the tube 32 in order to move a fluid (not shown) through the tube 32 in a direction indicated by the rotation area 92 without creating substantial fluid back pressure in a direction oppo ⁇ site that of the area 92.
- the spatial relationship provided by the mounting of the assembly head 26 and arcuate surface 32 is more clearly shown in Figure 3.
- each roller 28 includes a roller axis 100 which is generally parallel to the assembly head axis 96.
- the arcuate surface 34 is configured and the pump arm 36 positioned with respect to the assembly head 26 so that as the assembly head 26 is rotated in the direction of arrow 92, each roller 28 successively contacts the tube 32, gradually compresses and seals the tube 32 during approximately a 45° rotation of the assembly head 26.
- each roller to gradually release the tube during a rotation of the assembly head 26 of about 45°. This configuration also enables each roller to remain in a sealing engagement with the tube 32 during approximately a 90° rotation of the assembly head 26.
- each roller 28 has an inside diameter 118 which is smaller than roller diameters 120 at each end 122, 124 of each roller. This inside diameter 118 is constant between the end diameters 120 and the end diameters 120 are interconnected with the inside diameter 118 by arcuate surface 126.
- This generally U-shaped cross-section of the roller provides for uniform sealing tube 32 as shown in Figure 5 which is not possible with a flat or uniform diameter roller 130, see Figure 5a.
- the prior art roller 130 provides incomplete sealing of a tube 132 because the circular nature of the tube inside diameter results in end voids 134 136 unless sufficient pressure is exerted to collapsible the tube side 138.
- rollers 112 may lead to excessive tube wear and may further result in a excess loading on the assembly head 104 and rollers 112.
- collars 144 146 may be at- tached or molded into the tube at a spaced apart distance from one another in order that each collar is positioned abutting the housing front 40 upon assembly of the tube 32 into the housing 40 and around the rollers 28.
- the collar diameter is chosen in order to prevent entry of the collar into the housing means 40. It has been found that reliable and efficient perfor ⁇ mance of the pump is provided when the compressible and resilient tube is formed from silicon having a hardness of about 55 durometers, Shore A, platinum or peroxide cure method, and a typical tubing size is three-eighth inch.
- the tube is formed from a peroxide cure silicon, said cure being well known in the art.
- This size tube enables pumping volumes of up to about 40 cc/minute when the assembly head is rotated at up to about 75 rpm.
- Curves A in both Figures 6 and 7 represent the prior art pump performance while Curves B in Figures 6 and 7 represent the results of a peristaltic pump configured in accordance with the present invention.
- the vacuum variation on the intake of the pump 10 in accordance with the present invention operating at about 10 ccs per minute is less than plus or minus 4 mm Hg at a vacuum of about 18 mm Hg.
- This is to be compared with the vacuum variation on the intake of the prior art pump 102 which is about plus or minus 8 mm Hg at 10 ccs per minute.
- the change in back pressure of the pump 10 in accordance with the present invention over the prior art pump 102 is a factor of two.
