Description
- This Application claims priority of Taiwan Patent Application No. 097137881, filed on Oct. 2, 2008, the entirety of which is incorporated by reference herein.
- 1. Field of the Invention
- The invention relates to a thermo-pneumatic peristaltic pump, and more particularly to a thermo-pneumatic peristaltic pump that provides a reduced heating effect on a fluid transported thereby.
- 2. Description of the Related Art
- Generally, a biomedical micro electro-mechanical system (Bio-MEMS) is used for micro analytical instruments and accomplishes multiple inspections and analyses on a single chip, such as a lab-on-a-chip (LOC) or Bio-chip. Micro elements manufactured by a micro electro-mechanical processing technique may provide advantages of reduced manufacturing costs of detection instruments, reduced consumption of inspection reagent, reduced man-made operational errors, increased inspection and analysis speed, and enhanced sensitivity and accuracy, facilitating thorough research for related biological information.
- Fluidic control on the LOC or Bio-chip is often accomplished by a peristaltic pump. The peristaltic pump utilizes reciprocal motion of membranes to alter the volume of fluidic chambers, forcing a fluid in the fluidic chambers to flow in a specific direction. Moreover, the peristaltic pump may be categorized into electrostatic, shape-memory-alloy, thermo-pneumatic, piezoelectric, electromagnetic, and pneumatic types.
- Regarding a pneumatic peristaltic pump, a huge externally connected aeration device is required. The aeration device sends high-pressure gas into the pneumatic peristaltic pump to drive membranes therein to reciprocate, enabling flowing of a fluid. Although powerfully pushing the fluid forward, the pneumatic peristaltic pump is a huge and complex structure, thereby causing inconvenience of employment. To solve the aforementioned disadvantages, a thermo-pneumatic peristaltic pump can replace the pneumatic peristaltic pump to play a critical role in driving the fluid to flow in a micro fluidic system.
- Referring to
FIG. 1A andFIG. 1B , a conventional thermo-pneumaticperistaltic pump 1 comprises aheating base board 10, amembrane disposition board 20, and afluidic receiving board 30. - The
heating base board 10 comprises a plurality ofheaters 11, a plurality offirst electrodes 12 a, and a plurality ofsecond electrodes 12 b. Eachheater 11 is connected between eachfirst electrode 12 a and eachsecond electrode 12 b. Additionally, thefirst electrodes 12 a andsecond electrodes 12 b are electrically connected to a controller (not shown). - The
membrane disposition board 20 is disposed on theheating base board 10 and comprises a plurality ofmembrane chambers 21. Specifically, themembrane chambers 21 correspond to and cover theheaters 11, respectively. - The
fluidic receiving board 30 is disposed on themembrane disposition board 20 and comprises a plurality offluidic chambers 31, afluidic inlet 32, and afluidic outlet 33. Thefluidic chambers 31 sequentially connect to each other and are connected between thefluidic inlet 32 and thefluidic outlet 33. Additionally, thefluidic chambers 31 are disposed on themembrane chambers 21 of themembrane disposition board 20, respectively. - When the thermo-pneumatic
peristaltic pump 1 drives a fluid to flow, the controller performs sequential control for pushing the fluid. Namely, the controller sequentially electrifies theheaters 11 via thefirst electrodes 12 a andsecond electrodes 12 b, enabling heating operation of theheaters 11. Specifically, as shown inFIGS. 2A , 2B, and 2C, the controller electrifies only twoheaters 11 every time, heating air in closed spaces between the twoheaters 11 and twocorresponding membrane chambers 21. Here, the air in the closed spaces between the twoheaters 11 and the twocorresponding membrane chambers 21 is heated to expand, increasing the volume of the twocorresponding membrane chambers 21, and further forcing the twocorresponding membrane chambers 21 to bulge upward. In another aspect, when the controller stops electrifying acertain heater 11, the air in the closed space between theheater 11 and acorresponding membrane chamber 21 cools down, such that the volume of thecorresponding membrane chamber 21 returns to an original size and thecorresponding membrane chamber 21 does not bulge upward any more. Accordingly, by repeatedly and sequentially controlling the heating operation of theheaters 11 using the controller, the fluid can flow into thefluidic chambers 31 via thefluidic inlet 32 and flow out of thefluidic chambers 31 via thefluidic outlet 33. - Nevertheless, in practical application, the thermo-pneumatic
peristaltic pump 1 has many drawbacks. Because thefluidic chambers 31 are disposed right on theheaters 11, the fluid flowing through thefluidic chambers 31 is directly heated by theheaters 11 and thus provides an increased temperature, adversely affecting the structure or character of the fluid. Specifically, when the temperature of the fluid increases, the structure of the fluid may be damaged, bubbles may occur in the fluid, or the fluid may be vaporized. Thus, subsequent application, such as inspection and analysis, of the fluid output from the thermo-pneumaticperistaltic pump 1 is adversely affected. Moreover, as themembrane chambers 21 provide a limited volume, a fluidic pushing force generated by the thermo-pneumaticperistaltic pump 1 is limited. - A detailed description is given in the following embodiments with reference to the accompanying drawings.
- An exemplary embodiment of the invention provides a thermo-pneumatic peristaltic pump comprising a heating base board, a membrane disposition board, and a fluidic receiving board. The heating base board comprises at least one heater. The membrane disposition board is disposed on the heating base board and comprises at least one membrane chamber. The membrane chamber comprises a first chamber body and a second chamber body. The first chamber body connects to the second chamber body and covers the heater. The fluidic receiving board is disposed on the membrane disposition board and comprises at least one fluidic chamber, a fluidic inlet, and a fluidic outlet. The fluidic chamber is connected between the fluidic inlet and the fluidic outlet and is disposed on the second chamber body of the membrane chamber.
- The membrane chamber further comprises a connecting chamber body connecting the first chamber body to the second chamber body.
- The heating base board further comprises at least one first electrode and at least one second electrode. The heater is connected between the first and second electrodes.
- The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:

This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
- Referring to
FIG. 3A andFIG. 3B , a thermo-pneumaticperistaltic pump 100 comprises aheating base board 110, amembrane disposition board 120, and a fluidic receivingboard 130. - The
heating base board 110 comprises a plurality ofheaters 111, a plurality offirst electrodes 112 a, and asecond electrode 112 b. Eachheater 111 is connected between eachfirst electrode 112 a and thesecond electrode 112 b. Additionally, thefirst electrodes 112 a andsecond electrode 112 b are electrically connected to a controller (not shown). - The
membrane disposition board 120 is disposed on theheating base board 110 and comprises a plurality ofmembrane chambers 121. Eachmembrane chamber 121 comprises afirst chamber body 121 a, asecond chamber body 121 b, and a connectingchamber body 121 c. In this embodiment, each connectingchamber body 121 c connects eachfirst chamber body 121 a to eachsecond chamber body 121 b, and eachfirst chamber body 121 a covers eachheater 111. Additionally, themembrane disposition board 120 may be composed of Polydimethylsiloxane (PDMS). - The fluidic receiving
board 130 is disposed on themembrane disposition board 120 and comprises a plurality offluidic chambers 131, afluidic inlet 132 a, and afluidic outlet 132 b. Thefluidic chambers 131 are sequentially connected to each other and are connected between thefluidic inlet 132 a and thefluidic outlet 132 b. Specifically, eachfluidic chamber 131 is disposed on eachsecond chamber body 121 b of eachmembrane chamber 121 and diverges from eachfirst chamber body 121 a covering eachheater 111. - When the thermo-pneumatic
peristaltic pump 100 drives a fluid to flow, the controller performs sequential control for pushing the fluid. Namely, the controller sequentially electrifies theheaters 111 via thefirst electrodes 112 a andsecond electrode 112 b, enabling heating operation of theheaters 111. Specifically, the controller electrifies only twoheaters 111 every time, heating air in closed spaces between the twoheaters 111 and twocorresponding membrane chambers 121. Here, the air in the closed spaces between the twoheaters 111 and the twocorresponding membrane chambers 121 is heated to expand, increasing the volume of the twocorresponding membrane chambers 121, and further forcing the twocorresponding membrane chambers 121 to bulge upward. In another aspect, when the controller stops electrifying acertain heater 111, the air in the closed space between theheater 111 and a correspondingmembrane chamber 121 cools down, such that the volume of the correspondingmembrane chamber 121 returns to an original size and the correspondingmembrane chamber 121 does not bulge upward any more. Accordingly, by repeatedly and sequentially controlling the heating operation of theheaters 111 using the controller, the fluid can flow into thefluidic chambers 131 via thefluidic inlet 132 a and flow out of thefluidic chambers 131 via thefluidic outlet 132 b. - Moreover, the raised height of the central portion of each
conventional membrane chamber 21, i.e. the difference between the height of the central portion of eachmembrane chamber 21 after expansion and that before expansion, can be expressed by the following equation: -
- wherein, s denotes the raised height of the central portion of the
membrane chamber 21, V0 denotes the volume of the closed space between theheater 11 and the correspondingmembrane chamber 21 before heating, γ denotes the coefficient of expansion of air, ΔT denotes the temperature difference in themembrane chamber 21, and R denotes the radius of thefluidic chamber 31. - According to the equation above, when the values of γ and R are fixed, the value of s is in proportion to the values of V0 and ΔT. Namely, the value of s increases when the value of V0 increases and the value of ΔT is fixed, or the required value of ΔT for providing the same value of s reduces when the value of V0 increases.
- Accordingly, the thermo-pneumatic
peristaltic pump 100 provides many advantages as follows. Because thefluidic chambers 131 are not disposed right on theheaters 111, the fluid flowing through thefluidic chambers 131 is not heated directly by theheaters 111 and the temperature of the fluid is not increased as obviously as the case heating directly. Thus, the structure or character of the fluid can be stably maintained, benefiting subsequent application, such as inspection and analysis, of the fluid output from the thermo-pneumaticperistaltic pump 100. Moreover, as eachmembrane chamber 121 comprises afirst chamber body 121 a, asecond chamber body 121 b, and a connectingchamber body 121 c, the overall volume of eachmembrane chamber 121 is immensely increased, i.e. the value of V0 is immensely increased. Thus, after heated, eachmembrane chamber 121 provides an enhanced expansion effect, generating a greater fluidic pushing force. Additionally, as the overall volume of eachmembrane chamber 121 is immensely increased, the temperature difference therein may be selectively reduced (i.e. the value of ΔT may be selectively reduced), thereby reducing consumption of electric power. - While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
