Abstract
The invention relates to the technical field of medical instruments, in particular to a limb local administration and dialysis device which comprises a fixing mechanism, a limb local administration mechanism, a dialysis mechanism and a monitoring mechanism, wherein the limb local administration mechanism and the dialysis mechanism can be detachably arranged on the fixing mechanism, the monitoring mechanism is fixedly arranged on the fixing mechanism, the monitoring mechanism is matched with the dialysis mechanism, and the fixing mechanism comprises a bottom plate, a vertical plate, a first hook and a second hook. The invention can avoid the situation of wasting medical resources in the using process, can timely find and process when the coiled dialysis membrane is broken, not only can ensure the dialysis effect, but also can prevent the blood loss of a patient, and particularly, can avoid a large amount of dialysate from entering a blood circulation system of the patient to avoid potential safety hazards, is not easy to leak the blood during medicine adding, is convenient to use, and can effectively avoid the phenomenon that a pipeline connected with the dialysate is loosened.
Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a limb local administration and dialysis device and application thereof.
Background
With frequent occurrence of earthquakes, traffic accidents, landslides and the like, patients with limb crush injury and separation injury are more and more frequent; after limb blood supply is recovered by adopting techniques such as vascular anastomosis and the like, side effects such as hyperkalemia, hypermyoglobinemia and the like can occur, so that life is threatened. However, in other patients, such as diabetic feet, limited malignant tumors of limbs, osteomyelitis, etc., the concentration of the drug administered to the affected area through the intravenous route is too low to have the optimal effect, and the systemic drug concentration is too high, which may affect other organs. If the limb of the patient is extruded for a long time (at normal temperature, more than 6-7 hours), myocyte degeneration and necrosis can be caused, and a large amount of myoglobin, potassium ions, magnesium ions, phosphate radicals, sulfate radicals and non-protein nitrogen are released; after the heavy objects are removed, the toxic substances enter the blood circulation of the whole body, can cause acute renal failure and finally endanger life; i.e. reperfusion injury occurs. Therefore, once a serious limb crush injury is found, emergency incision and decompression are required; even, some patients have suffered from necrosis of the distal limb muscle segment due to mere blockage of a broken blood vessel, etc., and amputation is also performed in order to reduce the effect on the kidney function.
In addition, for the patients with limb fracture, especially the patients with limb fracture with developed muscles, when the limbs of the patients are not well preserved or the patients have a poor diagnosis; after the amputated limb replantation operation is carried out by the vascular anastomosis technology, the physiological and pathological changes similar to the extrusion syndrome can also appear on the whole body. Even if some patients have a timely visit, no replantation is advocated because of abundant muscle of the severed limbs (such as broken thigh).
In addition, diabetes and osteomyelitis are also more and more common; these patients may have bacterial and necrotic tissues entering the blood circulation to produce toxemia, and then have septic shock and death; although a large number of effective antibiotics may be used for treatment at this time, systemic application of such a large number of antibiotics distributes the drug throughout the body and not locally within the affected limb; sometimes, in order to achieve effective drug concentration in local lesions, the drug concentration is often required to be increased, so that other organs are easily damaged; and the treatment effect cannot be achieved even if the concentration is too low, and the antibiotic is easy to generate drug-resistant flora after long-term use. Some studies have shown that some patients have demonstrated blood-borne bacterial kill through blood culture, but the general condition continues to worsen. The heart muscle contraction force can be reduced due to the fact that blood flowing back to the heart through limb blood contains a large amount of cytokines such as TNF, IL6 and IL 8; meanwhile, a plurality of waterfall-like reactions can be stimulated, and a large number of inflammation mediums are expressed to cause secondary injury of tissues and organs of the body.
When a patient with limb malignant tumor is treated clinically, general chemotherapy of an anti-tumor medicament is usually carried out before limb protection of amputation or artificial limb replacement to avoid or reduce tumor emboli from entering general blood circulation, so that tumor metastasis of the pathway is prevented; but the anti-tumor medicine also has obvious influence on the normal tissues of the body. Therefore, the above-mentioned limited lesion treatment difficulties of these limbs are: 1 effective drugs should be distributed only in the affected limb; 2 avoid local toxic substances in the affected limb from flowing into the systemic blood circulation.
