Mechanically driven sequencing manifold

Abstract

A sequencing manifold for the purpose of supplying control and supply services of pre-determined temporal sequences to fluid processing assemblies is provided. The functioning of this sequencing manifold requires that translation be applied to the sequencing ports. Actuator mechanisms may supply such translation as either continuous motion or as a series of stepwise motions. Actuator mechanism can be obtained that rely on only mechanical means without the need for a source of electricity. With such actuators, it becomes feasible to conduct the operations of fluid processing assemblies in remote and primitive locations that lack a source of electricity. One skilled in the mechanical arts can provide various actuator mechanisms to meet these requirements.

Description

BACKGROUND

The desire for simple handheld analytical systems which use a fluid processing assembly to manage the performance of one or more tests with results that provide near real-time information is a growing opportunity in a number of markets. The tests involve the use of reagents that are optimized for a specific sample to provide one or more results that allow the user to make an informed decision. Managing the performance of the tests in the fluid processing assembly is facilitated with the implementation of fluid processing steps that mimic what one would do in a laboratory setting. A mechanism for performing the fluid processing steps involves managing the pressure drops in the fluid processing assembly to cause fluid movement in a controlled manner. The pressure drops are managed through external actuation supply lines whose states are controlled with electromechanical components.

The limitation of current electromechanical components is their cost, power consumption, limiting the use of batter power, or the need for a source of electricity. With complex actuation routines or to perform many tests at once, the number of electromechanical controls can be many. Confounding their application, the miniature electromechanical components needed for field portability are more expensive. Hence, it is difficult to implement in resource limited settings, such as remote or field-portable operations where low power consumption, low cost, ruggedness, and battery operation are desirable. By eliminating the need for the electromechanical components and hence the use of electricity to control fluid processing in the fluid processing assembly, the power requirement, portability, cost effectiveness, and ruggedness are vastly improved.

SUMMARY

The sequencing manifolds described in this application provide a means of managing sequenced fluid movements in a fluid processing assembly without the use of electromechanical components. The moving parts in the sequencing manifold program the sequence of supply services to the fluid processing assembly in a pre-programmed and controlled manner. The requirements for operation is the application of a mechanical force to drive the moving parts along the sequence of orifices that provide intermittent connections to the supply ports connected to the fluid processing assembly. The mechanical force can be provided by any of a number of non-electrical mechanisms including as an example, springs or manual operation. By managing the direction of movement of the moving parts in the manifold, the overall size of the sequencing manifold can be minimized to meet the need for portability and application in a remote environment.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The physical embodiments of the sequencing manifolds of this invention have the following attributes:

1. Three Plate Configuration, Coaxial Inlet and Outlet Orifices.

A a mechanically driven sequencing manifold is comprised of three plates arranged face-to-face. The outer two plates are to be maintained in fixed positions relative to each other. The outer two plates are designated Plate 1 and Plate 3. The inner plate is arranged to be translatable relative to the fixed plates. The inner plate is designated Plate 2.

The purpose of the arrangement of plates described above is to provide a temporal sequence of supply services to the pilot actuators of multiple diaphragm valves located on some fluid processing assembly in order to execute the functions of the fluid processing assembly. The additional purpose of this arrangement may be to provide a temporal sequence of supply services to the fluid handling channels within the fluid processing assembly. Depending upon the requirements of the fluid processing assembly, supply services may comprise some or all of the following: gases at sub-ambient pressures, gases at ambient pressure, gases at supra-ambient pressures, a vent to ambient pressure, as well as liquids at supra-ambient pressures. Collectively, these purposes will be referred to in the following descriptions of attributes as “supplying services to the fluid processing assembly”.

Plate 1, Plate 2, and Plate 3 contain ports that conduct the flow of supply services. A port is comprised of an inlet orifice and an outlet orifice. All of the ports referred to in this configuration have coaxial inlet and outlet orifices.

Plate 1 is penetrated by supply ports for one, or more, supply services. A single supply service may be connected to multiple supply ports via connections external to the sequencing manifold. An alternate configuration of these devices that achieves a similar result is presented in descriptions 2c, 4, 5, and 7c, below, wherein multiple connections of supply services are made using transfer channels internal to Plate 1.

Plate 3 is penetrated by control ports for directing sequentially timed supply services to the fluid processing assembly.

Plate 2 is penetrated by sequence ports that connect supply ports in Plate 1 to control ports in Plate 3 in a specific temporal sequence determined by the amount of translation of Plate 2 relative to Plate 1 (or equivalently, relative to Plate 3). The sequence ports in Plate 2 penetrate the complete thickness of Plate 2 such that the inlet orifice and outlet orifice of the sequence ports are coaxial. The sequence posts have various shapes, so as to provide the delivery of supply services to the fluid processing assembly in the required temporal sequences and for the required durations.

The combination of a supply port, a sequence port, and a control port that come into alignment on the sequencing manifold will be referred to as a sequencing gate. Multiple sequencing gates may be ganged together on the sequencing manifold.

The minimum cross sectional area of the ports that comprise a sequencing gate and associated transfer channels are determined by the mass flows demanded from the supply services by the fluid processing assembly. Larger dimensions may be included in the design to provide for reserve capacities or to facilitate fabrication.

The purpose of a sequencing gate is to provide control pulses of specific times of initiation and durations. The time of initiation of a control pulse will be determined by the location of the sequence port on Plate 2 relative to the associated control and supply ports and the translational velocity of Plate 2. The duration of a control pulse will be determined by the dimension of a sequence port in a direction “parallel” to the translation vector of Plate 2 divided by the translational velocity of Plate 2. Thus, many combinations of port locations, port dimensions, and translational velocities will provide control pulses of the same specific times of initiation and durations. Certain of these combinations may be more readily fabricated than others.

The surfaces of the plates in contact with each other are to be lubricated or have a lubricious coating. The lubricant or lubricious coating must be compatible with the materials of construction of Plate 1, Plate 2, and Plate 3. The three plates are held in close proximity using a mechanical clamping arrangement. The clamping force must be great enough to prevent leakage of supply service along unintended pathways from exceeding acceptable maximums. The clamping force must be modest enough to allow lineal translation of Plate 2 relative to Plate 1 and Plate 3. One skilled in the mechanical arts can provide many different clamping arrangements that achieve these goals.

The locations of the supply ports in Plate 1 are subject to few geometric limitations. One skilled in the art will be able to arrange supply ports in multiple configurations on Plate 1 that ultimately provide the same sequence of supply services to the fluid processing assembly.

The locations and shapes of the control ports in Plate 3 are subject to more rigorous geometric limitations. One skilled in the art will be able to arrange control ports in multiple configurations on Plate 3 that ultimately provide the same sequence of supply services to the pilot fluid processing assembly.

The geometric arrangements of the sequence ports in Plate 2 are highly constrained by the locations selected for the supply ports in Plate 1. The geometric arrangement and shape of the sequence ports in Plate 2 are further constrained by the locations selected for the control ports in Plate 3 and by the temporal sequence of supply services to be delivered to the fluid processing assembly required to execute the functions of the fluid processing assembly. In general, sequence ports will be arranged in lines or arcs “parallel” to the translation vector applied to the plate or cylinder containing the sequence ports.

There will be multiple configurations of supply ports, sequence ports, and control ports that ultimately provide the same sequence of supply services to the fluid processing assembly. One skilled in the art of microfabrication will be able to select configurations of all ports that can be fabricated within the constraints of existing fabrication techniques and that minimize the lineal translation required to achieve the desired temporal sequence of supply services to be delivered to the fluid processing assembly.

In preparation for operation of the sequencing manifold, the movable Plate 2 is brought to a reproducible initial position. During operation of the sequencing manifold, Plate 2 is then lineally translated past the fixed plates at a known linear velocity. In this manner, the various supply ports become connected to the various control ports through the sequence ports at specific times after initiation of lineal translation and for specific durations depending on the locations and shapes of the ports and the lineal velocity of translation. One skilled in the mechanical arts will be able to select actuator mechanisms suitable to provide the lineal translation of the movable Plate 2. The arrangement of supply, sequence, and control ports in the three plates that comprise a sequencing gate is depicted in FIG. 1, FIG. 2 and FIG. 3.

EXAMPLES

Example 1: Use of Sliding Manifold to Control Diaphragm Valve

A sliding manifold with the geometry depicted in FIG. 5 was used to control a diaphragm valve. In this example the supplies used were positive pressure (S1=+7 psi,) and vacuum (S2=−7 psi). The program plate was designed in order to supply alternatively S1 to close the diaphragm valve or S2 to open the diaphragm valve. FIG. 11 shows the temporal pressure profile and images of the open and closed diaphragm valve actuated by the manifold.

Example 2: Use of Sliding Manifold to Control Three Diaphragm Valves in Parallel and Achieve Peristaltic Pumping

A sliding manifold with a geometry comprising three repetitions of the device depicted in FIG. 5 was used to control three diaphragm valves in parallel. In this example the supplies used were positive pressure (S1=+7 psi) and vacuum (S2=−7 psi). The program plate was designed in order to supply alternatively S1 or S2 to each of the diaphragm valve. The sequence of operations in the program plate allow for actuation of the pumping routine described in FIG. 12. FIG. 12 also shows the valves actuated by the pumping sequence with the direction of flow. Performances of peristaltic pumping did not change when comparing actuation by a standard pneumatic controller, sliding manifold and sliding manifold with 30 s pauses between each step (FIG. 12).

Example 3: Use of Sliding Manifold to Implement Multistep Protocol in Fluid Processing Assembly

A sliding manifold comprising sixteen repetitions of the geometry depicted in FIGS. 1 and 2 was used to control 8 independent control ports (non-coaxial) and 5 independent supply ports (non-coaxial). This sliding manifold was used to implement a 12 steps protocol for controlling a fluid processing assembly capable of metering two volumes of liquid, mixing, de-bubbling and dispensing. The sequence of operation is described in FIG. 13.

FIG. 1 depicts only restricted segments of Plate 1 (101), Plate 2 (102), or Plate 3 (103). The full lateral extent of each plate has been omitted for the sake of clarity. As Plate 2 (102) translates past the supply port (201) in Plate 1 (101) and the control port (203) in Plate 3 (103), a temporal sequence of supply service pulses is produced as indicated in the graph on the right. The physical locations of sequence ports (104, 105, 106) in Plate 2 and the translational velocity determines the temporal sequence of when each control pulse is initiated. The dimension of each sequence port parallel to the translation vector and the translational velocity determines how long each control pulse persists.
