A droplet optical detection device

Abstract

The invention provides a droplet optical detection device. The droplet optical detection device comprises a laser device, a laser modulation power supply, a non-transparent droplet photoelectric detector, a transparent droplet photoelectric detector and detection signal processing equipment, wherein the laser modulation power supply is connected to the laser device, the non-transparent droplet photoelectric detector is located on the output light path of the laser device, the transparent droplet photoelectric detector and the non-transparent droplet photoelectric detector are arranged side by side, the transparent droplet photoelectric detector is located over the non-transparent droplet photoelectric detector, and both the non-transparent droplet photoelectric detector and the transparent droplet photoelectric detector are connected to the detection signal processing equipment. By adopting the optical detection method, dynamic non-contact detection of droplets is achieved, and it is guaranteed that droplets to be detected are not contaminated in the detection process; by adopting the single-light-source double detectors, the droplet detection stability is improved, transparent droplets and non-transparent droplets can be detected at the same time, and the droplet detection application range is widened; besides, the influence of ambient light on droplet detection is effectively avoided, and the droplet optical detection device has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of liquid drop detection, in particular to a liquid drop optical detection device. Background technique [0002] Droplet velocity detection is widely used in medicine, chemical industry, agricultural pesticide application and so on. The drop method is more commonly used in the micro-flow detection of liquids, and the flow rate of the liquid is determined by counting the drops per unit time. At present, when most hospitals are performing intravenous infusions on patients, the infusion status is manually observed by patients or nurses. Patients need to always pay attention to whether the drips are normal and whether the drips have been dripped. If abnormalities are found, the nurses should be notified. For elderly patients with limited mobility and infusion halls where many patients are infused at the same time, nurses have to spend a lot of time and energy paying attention to the infusion status all the time...

AI Technical Summary

Problems solved by technology

There are also a small number of hospitals that have adopted electronic infusion monitoring devices, but many devices can only detect the presence or absence of liquid medicine, but cannot detect abnormalities such as "running needles", infusion too fast or too slow, etc.

In addition, in chemical, pharmaceutical and other fields, many liquid droplets are detected by contact measurement, but these measurement methods often cause problems such as pollution, and some detectors use photoelectric detection, but they can only detect transparent liquid droplets, or Can only detect opaque droplets
