Embodiment 1
[0026] like figure 1 As shown, Embodiment 1 of the present invention provides a wound infection testing system, a gas collection device 1, a pure gas flushing device 2, a test device 3, an arithmetic unit 4, an air pump 5 and a controller 6;
[0027] The gas collection device 1 is arranged at the wound surface to be tested 10, the gas collection device 1 communicates with the test device 3 through the reversing valve 7, and is used to collect the gas to be tested released from the wound surface to be tested;
[0028] The air pump 5 communicates with the test device 3 through a closed gas valve 51, and is used to extract the gas 20 to be tested to the test device 3 for detection;
[0029] The arithmetic unit 4 is electrically connected to the test device 3, and is used for recording and analyzing the detection data of the test device 3;
[0030] The pure gas flushing device 2 communicates with the test device 3 through the reversing valve 7, and is used to flush the test devic...
Embodiment 2
[0064] The embodiment of the present invention provides a wound infection testing method, comprising the following steps:
[0065] Collect the gas to be tested released from the wound to be tested;
[0066] extracting the gas to be tested to the test device for detection;
[0067] Record and analyze the detection data of the test device;
[0068] flushing the test device;
[0069] The control detection process and the washing process are carried out alternately to realize multiple detections.
[0070] Preferably, the detection data of the test device is analyzed, specifically:
[0071] Divide multiple sets of detection data obtained from multiple detections into partitions, use a part of the recorded values whose detection time is earlier and whose fluctuation range is greater than the set range as the calibration value, and use the stabilized recorded value as the control value; Judgment and prediction of wound infection.
[0072] Preferably, judging and predicting the...

Abstract
The invention relates to the technical field of wound infection judgment, and discloses a wound infection testing system and method, wherein the system includes a gas collection device, a pure gas flushing device, a test device, an arithmetic unit, an air pump and a controller; At the wound surface, the gas collection device communicates with the test device through a reversing valve; the air pump communicates with the test device through a closed gas valve, and is used to extract the gas to be tested to the test device for testing; the calculator is electrically connected to the test device; pure gas flushing The device communicates with the test device through the reversing valve and is used to flush the test device; the calculator is electrically connected to the controller, and the controller is electrically connected to the reversing valve, closed air valve and air pump respectively, and is used to control the detection process and the flushing process Perform multiple detections alternately. The invention has the technical effect that the wound infection detection result fits the actual situation of the wound.
Description
technical field [0001] The invention relates to the technical field of wound infection judgment, in particular to a wound infection testing system and method. Background technique [0002] Wound infection can cause a variety of complications, which can be serious and life-threatening sepsis. Effective and accurate identification of the degree of infection at the early stage of infection can effectively and accurately control and treat the infection, and some cavities that are difficult to observe and require the use of dressings It is difficult to directly observe the specific conditions of the covered wound. Infected wounds form gas due to volatile products produced by microbial metabolism, and the gas produced by microbial metabolism contains a variety of organic gases such as alcohols, acids, amines, and ketones, as well as a variety of inorganic gases. [0003] Different gas analysis sensors can sense one or more corresponding gases, convert the concentration of differe...
