Problems solved by technology

But since this collector is still with the setting of the prior art, that is, it is far away from the drip nozzle of the Murphy's burette, it still cannot solve the problem of missed collection caused by the inclination of the Murphy's burette

Embodiment Construction

[0027] Below by specific embodiment, in conjunction with accompanying drawing, the technical solution of the present invention is described in further detail:

[0028] see image 3 and Figure 4 , a highly anti-interference liquid drop detection structure for a gravity infusion set, comprising a body 1 that clamps a Murphy's dropper 4 of a gravity infusion set through a U-shaped groove, and a body 1 that is arranged in the body 1 and positioned on two sides of the U-shaped groove Infrared tubes on the side. The body 1 includes a body base 11 forming a housing body, a body center column 12 disposed in the middle of the body base 11 , and an upper cover 13 disposed at the upper opening of the body center column 12 . A circuit board (not shown) of the detection device is provided in the body base 11 , and corresponding control keys and display screens (not shown in the figure) are provided on the front of the body base 11 .

[0029] The central column 12 of the main body is a ...

Abstract

The invention discloses a high anti-interference liquid drop detection structure for a gravity infusion set. The high anti-interference liquid drop detection structure comprises a structure body, a U-shaped groove formed in the body and infrared paired tubes arranged on the two sides of the U-shaped groove. An infrared emitting tube and an infrared receiving tube of the infrared paired tubes are arranged in a staggered mode within the range of the emitting angle of the infrared emitting tube or the range of the receiving angle of the infrared receiving tube, the infrared emitting tube or the infrared receiving tube is close to and aligned with a drip nozzle opening of a Murphy's dropper, and the infrared receiving tube or the infrared emitting tube is away from the drip nozzle opening. Through the staggered arrangement, under the condition that the Murphy's dropper inclines or shakes at a certain angle, an infrared detection formed by the infrared emitting tube and the infrared receiving tube can effectively detect a zero signal formed at the empty period between drops. The invention further discloses a high anti-interference liquid drop detection method. According to the method, zero signals at the two ends of an interference signal are used as the judging data for drop separation, inclination resistance and shaking resistance of a drop detection device are effectively improved, and drop detection accuracy is improved.

Description

technical field [0001] The invention relates to an infusion device, which belongs to the field of medical instruments. In particular, it relates to a medical droplet detection method and device. Background technique [0002] Intravenous infusion is a common treatment in clinical practice. However, in the current infusion treatment process, the infusion rate is usually controlled by turning the manual pulley on the infusion tube to control the flow rate of the liquid, which not only affects the expected therapeutic effect, but also for some sensitive patients who need to strictly control the infusion rate, even can lead to aggravation of the condition. [0003] With the popularization of infusion detection technology, many hospitals are equipped with infusion sets with infrared sensor detection. However, the detection accuracy of the infusion set for liquid droplets is still a problem, especially for the gravity infusion set, the environmental factors are more complicated....
