Description

The present invention relates to a medical drip warning device, which basically has the function of adjusting the dose of drip injection and has a warning function after injection to a predetermined amount. It has a perfect appearance, convenient operation and more complete warning functions, so as to ensure the safety of the injection patient and reduce the fatigue of the caregiver's family members due to continuous attention to the injection progress.

By the way, the drip injections received by ordinary patients usually take a long time because of the injection, so after the injection, the patient is often unconscious or has fallen asleep, and the family members or medical staff who take care of the patient cannot accurately grasp the actual completion time of the drip injection, so It is necessary to frequently travel between the sick beds to care about the progress of the injection. This phenomenon also consumes a considerable amount of attention and physical strength for the busy medical staff.

In addition, the volume of the drip bottle is usually fixed at 500 ml or 1000 ml. For patients who do not need so much injection dose, it is still done by visual inspection. The accuracy is certainly not scientific enough. At the same time, because the injection must be stopped halfway, Thereby the situation that expends the attention will be more than aforesaid for medical personnel and caregiver.

The purpose of the present invention is to make the gravity gradually decrease (injection into the human body) by hanging the drip bottle on the elastic element and the stretching relationship between the two due to the principle of gravity, so that the elastic force recovers and touches the set contact point , forming a short circuit, triggering the warning device to emit warning sound and light, to remind the patient or medical staff to deal with it in time to ensure the safety of the patient.

In addition, another advantage of focusing on the principle of gravity is that the material of the drip bottle will not be limited. In other words, no matter whether the drip bottle is made of glass or plastic material, the principle of gravity will be applicable and can be used in conjunction with the present invention.

That is, the main purpose of the present invention is to provide a buzzer to warn that the drip injection is completed, and the green, yellow, and red LEDs flash to display the power switch, the warning of insufficient power supply, and the flashing flashes that indicate the completion of the drip injection. .

Another object of the present invention is to provide a warning device structure consisting of an outer cover, an inner cover, an upper cover, a battery box, a spring, and an adjustment key group, so that the overall structure is complete and the adjustment operation is simple and convenient.
