Description

Technical Field

[0001] The present invention relates to the technical field of respirators, and in particular to a full-automatic intermittent water-flowing respirator. Background Art

[0002] The fully automatic intermittent flow-water respirator combines the characteristics of closed and flow-water respirators, and also reduces some of their problems. When the instrument is used, researchers generally design a series of short cycle periods according to the characteristics of the experimental subjects, including a measurement period in a closed state and a flushing period in an open state. During the measurement period, the inner circulation is turned on and the outer circulation is turned off, and the metabolic rate is measured in the closed state of the respiration chamber; while during the flushing period, the outer circulation is turned on and the inner circulation is turned off, so that the water in the respiration chamber is fully replaced with the saturated dissolved oxygen water in the water storage tank. The opening and closing of the pump driving the circulation is controlled by a programmable microcomputer multi-way time relay, which can set different cycle times according to needs. Therefore, after placing fish or other aquatic organisms in the metabolic respiration chamber, you only need to turn on the cycle program switch of the programmable microcomputer multi-way time relay, and the instrument will automatically perform intermittent flow-water metabolic rate measurement.

[0003] Traditional water-flowing respirators or closed respirators have the following disadvantages:

[0004] 1. Closed respirators will inevitably cause animals to experience progressive oxygen depletion (hypoxia) and increase the levels of carbon dioxide and nitrogenous waste in the breathing chamber, thus affecting the accuracy of experimental measurements;

[0005] 2. Flow-type respirators rely on a continuous flow of clean water. Although this can reduce or eliminate the problems of hypoxia, high levels of carbon dioxide and nitrogenous waste associated with closed-type respirators, it introduces new mixing and balance problems. If there is a small drift or error in the oxygen reading, or if the water flow through the oxygen probe changes, it will lead to larger experimental errors.

[0006] Therefore, providing a kind of respirator that can solve the above-mentioned shortcomings has become a technical problem to be solved by those skilled in the art. Summary of the invention

[0007] The technical problem to be solved by the present invention is how to provide a novel water-flowing respirator.

[0008] To achieve the above-mentioned purpose, the present invention provides a fully automatic intermittent water flow respirator, comprising: a water body component, an intermittent water flow control component and a data acquisition component, the water body component comprises a water bath and a water storage tank, a breathing chamber is arranged inside the water bath, the water storage tank is installed under the water bath, and the water storage tank is connected to an automatic temperature controller, the intermittent water flow control component comprises an intermittent water flow control box, and the data acquisition component comprises a multi-channel oxygen sensor and a computer.

[0009] This design forms a fully automatic intermittent water flow respirator. At the same time, the distance between the water tank and the water bath is short, which can reduce the length of the pipeline exposed to the outside world. This design can ensure the temperature difference between the circulating water and the air, avoid the formation of bubbles in the pipeline exposed to the air, thereby affecting the determination of dissolved oxygen, and ensure the accuracy of the experimental results. The automatic temperature controller includes a heater and a refrigerator, which are used to adjust the water inside the water tank according to demand. A drain pipe is preset at one end of the water tank, which is common knowledge and will not be repeated here.

[0011] Acrylic material has good transparency, which is convenient for experimenters to observe internal samples. Multiple breathing chambers can be set to different specifications. The design of multiple breathing chambers not only saves experimental time, but also makes it convenient for experimenters to compare and analyze multiple samples, further ensuring the accuracy of experimental results. In actual use, the corresponding number of breathing chambers can be selected according to actual needs.

[0012] Preferably, the water body component also includes an oxygenation pump, and the oxygenation pump is installed on one side of the water storage tank.

[0013] The oxygenation pump adopts an existing structure on the market. The oxygenation pump is connected to the water tank through a pipeline to achieve the purpose of continuously oxygenating the water tank.

[0014] Preferably, the intermittent water flow control component includes an intermittent water flow control box, and the intermittent water flow control box includes a power supply, a controller and a program switch, the power supply is a DC transformer, the controller is a programmable microcomputer multi-channel time relay, and there is more than one program switch.

[0015] This design forms a fully automatic intermittent water flow control system, which reflects the automation performance of the device and is convenient for experimenters to operate.

[0017] The peristaltic pump and flushing pump adopt the existing structure on the market. Each peristaltic pump and flushing pump is connected to the corresponding breathing chamber. Preferably, a pipe made of Norprene material is used for connection. Such a design can reduce the oxygen permeation value during internal circulation to a certain extent.

[0018] Preferably, regulating valves are provided on the outer surfaces of the peristaltic pump and the flushing pump, and the peristaltic pump and the flushing pump are connected in parallel with both ends of the breathing chamber.

[0019] The design of the regulating valve makes it easy for experimenters to adjust the flow of the peristaltic pump and the flushing pump according to needs, and the regulating valve is electrically connected to the intermittent water flow control box.

[0020] Preferably, one end of the multi-channel oxygen sensor is connected to a probe via a data cable, and the probe includes a pair of fiber optic oxygen probes and temperature probes. More than one temperature probe is provided corresponding to the fiber optic oxygen probe, and each temperature probe is immersed next to the corresponding breathing chamber.

[0021] The probe adopts the existing structure on the market. Each fiber optic oxygen probe detects the oxygen concentration of the water in the breathing chamber, and each temperature probe is used to detect the water temperature.

[0022] Preferably, the computer is connected to a multi-channel oxygen sensor via a data cable to record water oxygen concentration and temperature data.

[0023] The computer adopts the existing structure available on the market. With this design, the multi-channel oxygen sensor can transmit and save the data obtained from the detection on the computer, which is convenient for the experimenter to calculate the experimental results according to the corresponding formula later.

[0024] The beneficial effects of the present invention are:

[0025] 1. When the present invention is in use, the intermittent water flow respirator is designed by combining elements of water flow and closed respirators, and is composed of a series of cycles including a flushing period and a measurement period. The flushing period of the external cycle can reduce or eliminate potential problems such as hypoxia, high levels of carbon dioxide and nitrogenous waste in the respiration chamber, while the measurement period of the internal cycle can reduce the errors caused by the mixing and balance of water oxygen, thereby improving the accuracy of the measurement.

[0026] 2. When the present invention is in use, the intermittent water flow control component cooperates with the design of the data acquisition component, which reflects the full automation of the measurement and is suitable for promotion.

[0027] 3. When the present invention is in use, the length of the pipe exposed to the outside is shortened as much as possible. Such a design can ensure the temperature difference between the circulating water and the air, avoid the generation of bubbles in the pipe exposed to the air, and further ensure the accuracy of the measurement of the respiratory metabolic rate of the sample.
