Background technique

When the patient is transfused in the hospital, he usually needs the care of nurses or family members. When the fluid is transfused, if he fails to find out in time, it will bring great trouble to the patient and even cause life-threatening.

At present, hospitals mostly adopt the method of hanging vertical pressure drop when infusing patients with patients (injection injection or intravenous drip). The infusion net is used to hang the infusion bottle, which will not only waste some time when looking for a suitable infusion net. , and the infusion set can only be inserted into the infusion bottle after the infusion bottle is put into the infusion net. unavailable conditions.

Moreover, there is another important problem during infusion: when the dripping liquid in the infusion bottle is used up, the nurse needs to pull out the needle or refill the bottle. When the bottle needs to be refilled, the air will enter the dropper, which is difficult to get rid of, and the patient may need a second injection, which increases the work intensity of the nurse and the patient has to endure the pain caused by another injection; if the air enters the blood vessel accidentally, it will It has a very adverse effect on the human body, and may cause serious medical accidents or conflicts between doctors and patients. For this reason, when remaining dripping liquid in the drop bottle is not many, patient or accompanying person needs to observe at any time, and patient can't get a good rest, and accompanying person also takes great pains.

Therefore, people need a kind of medical liquid level limit alarm device to solve the above problems.

When the telescopic rod 2-12 moves downward, the air compressor 2-13 is compressed by the slide rod 2-121, so that the air in the air compressor 2-13 enters the air groove through the air inlet, so that the clamping plate 2-22 shrinks into the clamping shell 2-21 under the push of the air, so that the infusion set can be in the middle position of the clamping shell 2-21. When the sub-controller 3-12 needs to control the flow rate of the liquid medicine, the sub-controller 3 -12 will control the electric control valve to release air, due to the release of air in the air tank, the clamping plate 2-22 will stretch out the clamping shell 2-21 under the action of the elastic potential energy of the clamping spring 2-222 and press the infusion set Clamping makes the circulation of the infusion set change, so as to achieve the control of the infusion speed.
