Nursing liquid flow rate adjusting device

Abstract

The invention relates to a nursing liquid flow rate adjusting device which comprises an infusion tube and a side adjusting device. A side branch tube is arranged on a side surface of the infusion tube, a fixing bottom ring is arranged at the tail end of the side branch tube, external threads are arranged on the outer wall of the fixing bottom ring, and an accommodating groove is formed in the inner wall of the side, which is far away from the side branch tube, of the infusion tube; the side adjusting device comprises an upper limit component, a speed adjusting insertion rod, an adjusting cushion ring, adjusting bolts and a compression spring. The nursing liquid flow rate adjusting device has the advantages that the nursing liquid flow rate adjusting device is reasonable in structure and convenient and easy to assemble, and batch production can be facilitated; the infusion rate can be adjusted in normal stage; medicines can be quickly administered in emergency states, compression damping of the speed adjusting insertion rod further can be adjusted, and quick medicine administration functions further can be disabled; excessive medicines due to quick medicine administration for long time can be prevented by delayed alarm.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nursing liquid flow rate regulating device. Background technique [0002] In clinical nursing work, patients need to be infused, and the requirements for different drug infusion rates are different. Common drugs need to be delivered slowly, while drugs such as mannitol need relatively fast delivery speeds, and common infusion devices can meet the above requirements. [0003] However, in some emergency situations, instant and rapid drug administration is required, such as blood transfusion for patients with massive bleeding during surgery, some drugs delivered in the emergency room, and even painkillers delivered to patients after surgery. Taking painkillers as an example, in the prior art, the painkiller pump is often used to slowly deliver the painkiller to the patient, but when the patient is in unbearable pain, it needs to be administered quickly for pain relief.

Taking painkillers as an example, in the prior art, the painkiller pump is often used to slowly deliver the painkiller to the patient, but when the patient is in unbearable pain, it needs to be administered quickly for pain relief. The painkiller pump in the prior art can Squeeze out the medicine, but the existing pain relief pumps have the following problems: 1. The structure is complex and expensive; 2. The damping of the squeezed medicine cannot be adjusted. The patient turned over and squeezed on the pain pump, resulting in long-term rapid drug administration and causing danger
