A new type of pressurized infusion device with refrigerated side tube drug delivery function

Abstract

The invention relates to a novel infusion pressurizing and refrigerating side duct dosing device. The novel infusion pressurizing and refrigerating side duct dosing device comprises a case body and a case cover; the inside of the case body is provided with a thrombolytic drug bottle, a vacuum pump, a variable speed motor, a rolling pressure roller, a computer control chip and a opposite-type drop monitoring sensor, wherein the thrombolytic drug bottle is arranged on one side of the internal top of the case body, the bottom of the thrombolytic drug bottle is connected with a movable thrombolytic drug injecting button which is arranged on the upper wall of the case body, and a thermal insulating layer is arranged outside the thrombolytic drug bottle and fixed at the top of the case body; the vacuum pump is arranged under the thrombolytic drug bottle and right opposite to the bottleneck of the thrombolytic drug bottle; the variable speed motor is arranged under the vacuum pump and connected with the vacuum pump; the rolling pressure roller is arranged at the bottom of the case body under the variable speed motor; the variable speed motor is also connected with the central axle of the rolling pressure roller; a section of infusion pipe connected with the lower portion of a drip cup is arranged between the rolling pressure roller and the bottom of the case body. The novel infusion pressurizing and refrigerating side duct dosing device solves the problem of thrombogenesis due to infusion cease caused by blood pressure fluctuation during intravascular intervention.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a novel pressurized transfusion device with a refrigerated side tube for drug delivery. Background technique [0002] With the advancement of medical technology, the clinical application of endovascular interventional surgery has become more and more. During the operation of endovascular intervention, it is often necessary to pressurize the arterial sheath and the infused saline (or heparin water) in the catheter to resist the arterial pressure and prevent the arterial blood from staying in the catheter or even flowing back into the catheter And the infusion set, causing thrombus formation, damaging the patient's health, and even endangering the patient's life. In clinical practice, commonly used infusion pressurized bags need to be manually pressurized for 500ml of liquid. Due to endovascular interventional surgery, especially neurological interventional su...

AI Technical Summary

Problems solved by technology

Manual replacement is not only a heavy workload, but also needs to suspend the operation, which affects the operation process

If the exhaust is not complete, it may cause air embolism; if the pressure is not in place, or the saline is not replaced in time, it may cause thrombosis and endanger the health of the patient

In addition, as the patient's blood pressure fluctuates, the infusion rate of perfusion saline may change accordingly. After the blood pressure rises, it may cause perfusion stop or reverse flow, causing thrombosis

In addition, once acute thrombosis occurs during interventional surgery, antithrombotic drugs need to be given. If the medicine is taken and prepared on site, it will delay a lot of time and delay treatment.
