A device for local drug delivery and dialysis of extremities and its application

Abstract

The invention relates to the technical field of medical devices, in particular to a device for local drug delivery and dialysis of limbs, including a fixing mechanism, a local drug delivery mechanism for limbs, a dialysis mechanism and a monitoring mechanism. In terms of mechanism, the monitoring mechanism is fixedly installed on the fixing mechanism, and the monitoring mechanism is arranged in cooperation with the dialysis mechanism. The fixing mechanism includes a bottom plate, a vertical plate, a first hook and a second hook. The present invention can avoid the waste of medical resources in the process of use, and can detect and deal with the rupture of the coiled dialysis membrane in time, which can not only ensure the dialysis effect, but also prevent the patient from losing blood. It can prevent a large amount of dialysate from entering the patient's blood circulation system and eliminate potential safety hazards. It is not easy to cause blood leakage when adding medicine. It is more convenient to use and can effectively avoid the loosening of the pipeline connected to the dialysate.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a local drug delivery and dialysis device for extremities and its application. Background technique [0002] With the frequent occurrence of earthquakes, traffic accidents, landslides, etc., more and more patients with limb crush injuries and severed injuries; Symptoms and other side effects can be life-threatening. For other patients, such as diabetic foot, malignant tumors with localized limbs, osteomyelitis, etc., the drug concentration in the lesion area is too low to achieve the best effect through intravenous administration, and the systemic drug concentration is too high. influences. If the patient's limbs are squeezed for too long (at room temperature, more than 6 to 7 hours), it can cause muscle cell degeneration and necrosis, and release a large amount of myoglobin, potassium ions, magnesium ions, phosphate, sulfate, and non-protein nitroge...

AI Technical Summary

Problems solved by technology

[0007] 1) It integrates the arterial cavity and the venous cavity. When only local administration or dialysis is required, this makes it not fully utilized after use (the arterial cavity is useless or the venous cavity is useless. Useless), still need to be treated as medical waste after use, therefore, causing a waste of medical resources during its use;

[0008] 2) It cannot monitor whether the membrane of the blood coil is broken in real time during use. When the membrane of the blood coil breaks, it will not only affect the dialysis effect, but also cause the patient to lose blood. More importantly, it is likely to cause a large number of The dialysate enters the patient's blood circulation system and there are potential safety hazards;

[0009] 3) When it is used, blood leakage often occurs at the drug administration inlet, and the connection between the arterial blood inlet and the arterial blood outlet is inconvenient, which makes it inconvenient to use;

[0010] 4) When it is in use, it is inconvenient to connect the venous blood inlet and venous blood outlet, and the dialysate inlet and dialysate outlet often have loose pipes when connecting the dialysate pipes
