Description

Technical Field

[0001] The utility model relates to the technical field of end-tidal carbon dioxide monitoring, in particular to a dehumidifying device for a carbon dioxide monitoring tube. Background Art

[0002] At present, during the operation, it is necessary to monitor the carbon dioxide in the exhaled gas of the patient. This process is end-tidal carbon dioxide (ETCO2) monitoring, which is a non-invasive clinical monitoring technology. ETCO2 monitoring can reflect ventilation, respiratory and circulatory functions, and metabolic status, and is of great significance for evaluating whole-body metabolism, cardiac output, pulmonary perfusion volume, and ventilation volume. Its principle is based on the fact that the diffusion ability of carbon dioxide is much higher than that of oxygen, and the lung function is evaluated by monitoring the carbon dioxide concentration in the exhaled gas.

[0003] Since the exhaled gas of the human body contains a certain amount of humidity, and the carbon dioxide monitoring tube introduced into the monitor is usually a thin flexible tube. With long-term use, a lot of condensed water often appears in the pipeline. These condensed waters will affect the smoothness of the pipeline, the gas throughput, and cause inaccurate carbon dioxide monitoring. At present, most medical staff use the method of manually shaking the pipeline after disassembly or a large amount of ventilation to empty the condensed water in the carbon dioxide monitoring tube. When performing the above operations, the monitoring of carbon dioxide gas will be interrupted, and medical staff need to often observe the condition of the pipeline, which is rather inconvenient. Therefore, in order to solve the foregoing problems, we propose a dehumidifying device for a carbon dioxide monitoring tube. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a dehumidifying device for a carbon dioxide monitoring tube.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A dehumidifying device for a carbon dioxide monitoring tube, including a control box. The left and right sides of the top of the control box are respectively fixedly installed with a heating box and a condensation box. The tops of the heating box and the condensation box are respectively fixedly installed with an air outlet pipe and an air inlet pipe. The top ends of the air inlet pipe and the air outlet pipe are fixedly installed with a connecting pipe. Pipeline connectors are fixedly installed at both ends of the connecting pipe. A drain pipe is fixedly installed below one side of the condensation box;

[0007] A semiconductor refrigeration sheet is fixedly installed between the heating box and the condensation box. The cold end of the semiconductor refrigeration sheet is located inside the condensation box, and the hot end of the semiconductor refrigeration sheet is located inside the heating box. A communicating pipe is fixedly installed above the left side of the condensation box, and the left end of the communicating pipe extends to the lower part inside the heating box. The control box is electrically connected to the semiconductor refrigeration sheet.

[0008] Further, a controller is fixedly installed on the front surface of the control box, and a storage battery is fixedly installed inside the control box. The storage battery and the semiconductor refrigeration sheet are both electrically connected to the controller.

[0009] Further, control valves are fixedly installed inside the intake pipe, the exhaust pipe, the drain pipe, and the connecting pipe. The control valve inside the connecting pipe is located between the exhaust pipe and the intake pipe.

[0010] Further, the bottom end of the intake pipe extends into the condensation box and is fixedly installed with a shunt pipe. A plurality of air blowing pipes are equidistantly and fixedly installed below the outer surface of the shunt pipe. The cold end of the semiconductor refrigeration sheet is fixedly installed with heat dissipation fins. A plurality of the air blowing pipes are inserted into the heat dissipation fins, and the plurality of air blowing pipes and the plurality of fins of the heat dissipation fins are arranged at intervals.

[0011] Further, an air diffusing pipe is fixedly installed at the left end of the communicating pipe. A plurality of air outlet holes are equidistantly formed above the outer surface of the air diffusing pipe. The air diffusing pipe is located below the hot end of the semiconductor refrigeration sheet.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The device can dehumidify and dry the gas introduced into the carbon dioxide monitoring pipe, avoiding the blockage of the pipeline due to the condensation water in the carbon dioxide monitoring pipe during long-term monitoring, which affects the monitoring of carbon dioxide. And when the control valves inside the intake pipe and the exhaust pipe are in the closed state and the control valves inside the drain pipe and the connecting pipe are in the open state, the condensation water inside the condensation box will be directly discharged through the drain pipe, and the gas discharged from the breathing pipe can directly enter the carbon dioxide monitoring pipe through the connecting pipe, realizing that carbon dioxide monitoring can still be carried out when emptying the condensation water, improving the safety during the operation.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention;

[0021] Refer to Figures 1-4 , a dehumidifying device for a carbon dioxide monitoring tube, including a control box 1. The left and right sides of the top of the control box 1 are respectively fixedly installed with a heating box 3 and a condensation box 2. The tops of the heating box 3 and the condensation box 2 are respectively fixedly installed with an exhaust pipe 7 and an intake pipe 6. The tops of the intake pipe 6 and the exhaust pipe 7 are fixedly installed with a connecting pipe 5. Pipe connectors are fixedly installed at both ends of the connecting pipe 5. A drain pipe 4 is fixedly installed below one side of the condensation box 2; a thermoelectric cooler 8 is fixedly installed between the heating box 3 and the condensation box 2. The cold end of the thermoelectric cooler 8 is located inside the condensation box 2, and the hot end of the thermoelectric cooler 8 is located inside the heating box 3. A connecting pipe 11 is fixedly installed above the left side of the condensation box 2. The left end of the connecting pipe 11 extends to the lower part inside the heating box 3. The control box 1 is electrically connected to the thermoelectric cooler 8.

[0022] The connecting pipe 5 can be connected to the carbon dioxide monitoring tube and the breathing tube through the pipe connectors at both ends. The gas in the breathing tube can enter the condensation box 2 through the connecting pipe 5 and the intake pipe 6. The cold end of the thermoelectric cooler 8 is fixedly installed with heat dissipation fins 9. The cold end of the thermoelectric cooler 8 can cooperate with the heat dissipation fins 9 to condense the gas, thereby removing the moisture in the patient's exhaled gas to a certain extent. Then, the dry gas can enter the heating box 3 through the connecting pipe 11. After the hot end of the thermoelectric cooler 8 heats the gas, it is discharged to the carbon dioxide monitoring tube through the exhaust pipe 7 and the connecting pipe 5, so as to realize the dehumidification of the gas entering the carbon dioxide monitoring tube, and avoid the condensation water in the carbon dioxide monitoring tube blocking the pipeline during long-term monitoring, affecting the monitoring of carbon dioxide.

[0023] A controller is fixedly installed on the front of the control box 1. A storage battery is fixedly installed inside the control box 1. The storage battery and the thermoelectric cooler 8 are both electrically connected to the controller. Medical staff can control the power of the thermoelectric cooler 8 through the controller to improve its heating and condensation effects. The storage battery can provide the required power for this device.

[0024] Control valves are fixedly installed inside the intake pipe 6, the exhaust pipe 7, the drain pipe 4 and the connecting pipe 5. The control valve inside the connecting pipe 5 is located between the exhaust pipe 7 and the intake pipe 6;

[0025] The on-off of the air inlet pipe 6, the air outlet pipe 7, the liquid discharge pipe 4 and the connecting pipe 5 can be realized by controlling the control valve; during normal dehumidification, the control valves inside the liquid discharge pipe 4 and the connecting pipe 5 are in the closed state, and the control valves inside the air inlet pipe 6 and the air outlet pipe 7 are open. Liquid cannot pass through the liquid discharge pipe 4, and gas cannot directly enter the carbon dioxide monitoring pipe through the connecting pipe 5. The gas needs to pass through the condensation box 2 and the heating box 3 before entering the carbon dioxide monitoring pipe;

[0026] When emptying the liquid in the condensation box 2, the control valves inside the air inlet pipe 6 and the air outlet pipe 7 are in the closed state, and the control valves inside the liquid discharge pipe 4 and the connecting pipe 5 are open. The condensed water inside the condensation box 2 will be directly discharged through the liquid discharge pipe 4, and the gas discharged from the breathing pipe can directly enter the carbon dioxide monitoring pipe through the connecting pipe 5, enabling carbon dioxide monitoring to be carried out while emptying the condensed water and improving the safety during the operation.

[0027] The bottom end of the air inlet pipe 6 extends into the interior of the condensation box 2 and is fixedly installed with a shunt pipe 12. A plurality of air blowing pipes 13 are fixedly installed at equal intervals below the outer surface of the shunt pipe 12. A plurality of air blowing pipes 13 are all inserted into the interior of the heat dissipation fins 9, and the plurality of air blowing pipes 13 are arranged at intervals with the plurality of fins of the heat dissipation fins 9;

[0028] By shunting the gas and blowing it towards the heat dissipation fins 9, the heat exchange effect between the gas and the heat dissipation fins 9 can be improved, and at the same time, the blown gas can blow off the condensed water on the heat dissipation fins 9, facilitating the collection of the condensed water.

[0029] The left end of the connecting pipe 11 is fixedly installed with a gas dispersing pipe 10. A number of air outlet holes are equidistantly opened above the outer surface of the gas dispersing pipe 10, and the gas dispersing pipe 10 is located below the hot end of the semiconductor refrigeration sheet 8.

[0030] Through the arrangement of a plurality of air outlet holes, the dried gas can be dispersed and blown towards the hot end of the semiconductor refrigeration sheet 8, improving the heat exchange effect between the gas and the hot end of the semiconductor refrigeration sheet 8.
