The micro-flow oxygen supply mechanism comprises an oxygen storage part 300, an oxygen concentration sensing part 400 and a peristaltic pump 500, wherein the molecular sieve oxygen generation mechanism conveys an oxygen source to the oxygen storage part 300 through an oxygen outlet control group by an oxygen source pipeline 210 output by the molecular sieve part 200, the oxygen source is controlled to be output by the peristaltic pump 500 after flowing through the oxygen concentration sensing part 400, and the accurate control output of the oxygen flow of 6-600ml/h can be realized by adopting oxygen storage control and peristaltic pump output control in the embodiment.

If an oxygen supply system of a hospital is connected (the flow is generally 0.5L/min) to obtain oxygen, the oxygen is applied to a wound site, the flow level (in liters per minute) is thousands of times of the micro-flow level (in milliliters per hour), the oxygen supply control is difficult to precisely control, the position is fixed and cannot be moved, when the oxygen flow is too large, the wound surface part can be dried, the moist state cannot be maintained, and the healing of the wound surface is not facilitated.

It should be noted that, because the oxygen-enriched space formed between the external micro-flow oxygen supply device and the wound or the wound surface is supplied with oxygen (the conventional space requires hundreds of ml of oxygen to reach the oxygen-enriched state), and the oxygen-making amount (generally below 10 ml/h) of the traditional wound oxygen therapy apparatus is low, a slow oxygen supplementing process is required when the traditional wound oxygen therapy apparatus is started to be used, so that the oxygen-enriched state can be reached to enter the optimal oxygen therapy environment.
In an alternative embodiment, the molecular sieve oxygen generating mechanism and the oxygen storage part can ensure enough oxygen sources, control the oxygen generating output of the peristaltic pump (the peristaltic pump of the embodiment can realize 6-600ml/h oxygen output control) to perform hump curve oxygen supply, provide larger oxygen supply 400ml/h for the external micro-flow oxygen supplier in the initial use stage, and adjust the oxygen flow output to 3-6ml/h to perform micro-flow output oxygen supply under the condition that the oxygen-enriched state is satisfied between the external micro-flow oxygen supplier and a wound or a wound surface, so as to avoid waiting for slow oxygen supplementing process when the use is started.
The oxygen pressure of the oxygen source output by the peristaltic pump is monitored by the second oxygen pressure monitoring unit and the oxygen pressure output by the second tank body is monitored by the first oxygen pressure monitoring unit in the oxygen supply stage, when the oxygen pressure deviates from a preset pressure threshold value, the molecular sieve oxygen generating mechanism is controlled to be started, the control end B of the first three-way electromagnetic valve is controlled to be opened at the moment, so that the first exhaust pipeline is in a conducting state, the oxygen source with the oxygen concentration which does not reach the standard when the molecular sieve oxygen generating mechanism is started again is discharged, after the operation is set for a set time (about 2 minutes, the oxygen source can be further monitored by the oxygen concentration sensing according to the performance setting of the molecular sieve oxygen generating mechanism, the oxygen generating control adopts a conventional means, other forms of limitation are not carried out on the embodiment), the control end B of the first three-way electromagnetic valve is closed, the control end E of the second three-way electromagnetic valve is controlled to stop exhaust and simultaneously convey the oxygen source to the micro-flow oxygen supplying mechanism, then the oxygen storage part is started to perform the oxygen storage step, and then the circulation operation is performed, so that the wound and the wound surface is healed with micro-flow oxygen.
The foregoing disclosure is merely illustrative of one or more of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model in any way, as it is intended to cover all modifications, variations, uses, or equivalents of the utility model that fall within the spirit and scope of the utility model.
