Description

Transfusion stand

Technical Field

The technical scheme of the invention relates to an infusion support, in particular to equipment adopting a lower rod piece, a connecting sleeve, a middle rod piece, an upper rod piece, a rotating disc, a controller, a buzzer and a funnel-shaped support, and belongs to the field of medical equipment.

Background

The infusion stand is one of indispensable medical facilities in medical units, and is often used in various infusion occasions. The medical infusion support used clinically at present usually comprises infusion rod and couple, and the infusion rod provides the supporting role by objects such as base, nursing bed or seat, though this type of infusion support simple structure, the function is single. When the liquid medicine is nearly completely transfused, the liquid medicine transfusion device does not have the functions of prompting and closing a pipeline, a patient or an accompanying person is required to actively observe the liquid medicine frequently, and the situation of completely transfusing the liquid medicine due to human negligence often occurs.

If the liquid medicine is completely infused, air enters the infusion pipeline, on one hand, if the infusion needs to be continued, a professional is required to discharge the air in the pipeline, the operation is time-consuming and labor-consuming, and if necessary, the needle needs to be pulled up and punctured again, so that extra pain is brought to a patient; on the other hand, after the liquid medicine in the container is completely infused, the pressure of the liquid medicine in the infusion pipeline is gradually reduced, the phenomenon of blood return is easy to occur, and unnecessary psychological burden is caused to a patient; the above situation is also one of the non-negligible causes of doctor-patient contradiction in clinical practice.

Meanwhile, patients can continuously input a plurality of bottles of liquid medicines in the process of infusion, and often nurses or accompanying personnel are needed to pull out the bottle plug puncture outfit of the disposable infusion apparatus to replace the medicine bottle in the process of infusion, but the medicine bottle replacement becomes quite difficult under the condition that the patients do not carry accompanying personnel and nurses are just absent. At the same time, this action of changing the vial also adds considerable work to the nurse.

To foretell needs the patient to pay close attention to the liquid medicine surplus often, the liquid medicine is wasted time and energy after being defeated to the end and needs patient or nurse to change the problem of medicine bottle, so need design a device, it can realize no longer needing the surplus that the patient paid close attention to the liquid medicine, the condition that the liquid medicine is defeated to the end can not appear, and can change the medicine bottle automatically, reports to the police voluntarily after last bottle of liquid medicine is defeated to the while, reminds patient and nurse in time to pull out the syringe needle.

Disclosure of Invention
