Problems solved by technology
However, increasing the number of infrared receiving devices has the following disadvantages: increased cost; increased difficulty in hardware design; increased space occupied by equipment
If a part of the droplet is within the range of the gap, the size of the part cannot be detected, resulting in an error in the size recognition of the droplet

The invention discloses transfusion detection equipment used for liquid drop identification. The transfusion detection equipment comprises an infrared emission device, an infrared receiving device and an infrared light reflecting device, wherein the infrared receiving device is adjacent to the infrared emission device; the infrared light reflecting device is opposite to the infrared emission device and the infrared receiving device, and is used for reflecting the infrared light emitted by the infrared emission device; the infrared receiving device receives the reflected infrared light, and is used for identifying whether a liquid drop drops down from a transfusion dropper or not. The invention further discloses a transfusion detection method used for liquid drop identification. According to the invention, only one infrared receiving device is adopted; liquid drop identification space range of a plurality of infrared receiving devices in the conventional method can be achieved; the size of the liquid drop can be identified accurately in a relatively large space range without being affected by the clearance among the infrared receiving devices; as only one pair of infrared receiving and emission devices are adopted in the transfusion detection equipment, the hardware is simplified to the maximum extent; the size of the equipment is reduced while the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of infusion detection, in particular to an infusion detection device for liquid drop recognition and an infusion detection method for liquid drop recognition. Background technique [0002] The current infusion detection equipment uses an infrared emitting device and an infrared receiving device, which are installed on both sides between the drop opening and the liquid surface of the dropper. The infrared receiving device continuously detects the energy of the light from the infrared emitting device, and when no liquid drop falls, the energy value is a steady-state energy value. When a liquid drop falls and passes through the connection between the infrared emitting device and the infrared receiving device, the energy of the light that can be detected by the infrared receiving device will decrease due to the blocking of the light by the liquid droplet. Based on this energy drop, it is possible to recognize w...
