Description

Peritoneal irrigation drainage device

Technical Field

The utility model belongs to the technical field of medical instrument and specifically relates to an abdominal cavity washes drainage device.

Background

Severe Acute Pancreatitis (SAP) is a common disease with multiple etiologies and complications, SAP is a disease with high morbidity and high fatality rate, and particularly under the condition of severe pancreatic necrosis, the fatality rate is as high as 15% -45%; infectious pancreatic necrosis is associated with high mortality, while peritoneal lavage can significantly reduce morbidity and mortality; infectious Pancreas Necrosis (IPN), should highly regard the management of postoperative drainage tube, in time adjust the drainage tube position according to the image evaluation result, wash the drainage tube actively, suitably change drainage tube etc. of bigger model to this keeps the drainage tube unobstructed, drainage pancreas or pancreas week necrotic tissue to furthest.

Escalating therapeutic strategies have become the mainstay strategy for the treatment of infectious pancreatic necrosis; when in operation, the affected side is lifted, a cut protective film is attached, the original drainage tube is pulled out, the sinus tract is gradually expanded to F24-F30, an ultrasonic lithotripsy nephroscope or a fiber choledochoscope is selected to enter the cavity space through a sheath tube according to the distance and the angle between the sinus tract and the necrotic cavity space, the cavity space is continuously washed by warm physiological saline to obtain a good visual field, and the loosened and fallen necrotic tissue is taken out by the forceps; forcibly taking out the necrotic tissue which is not completely shed, and placing the three-cavity drainage tubes from F20 to F28 or the pigtail catheter at the deep part of the necrotic pustule cavity to be close to the pancreatic bed as far as possible after the necrotic tissue is taken out; the drainage liquid and the removed necrotic tissue are subjected to pathogenic and pathological examination in a conventional way, and the drainage is kept smooth by adopting a mode of combining bedside manual flushing and continuous lavage after the operation, and the catheter is actively cleaned or replaced according to the drainage condition; controlling the source of infection and ensuring that drainage is unobstructed are the most important principles for the treatment of such cases. After the drainage tube is placed, the effective drainage of an infected stove is achieved by frequently flushing the pipeline and adjusting the position and the caliber of the pipeline, and the drainage tube is closely observed after the operation; the normal drainage liquid color is light bloody nature or faint yellow abdomen water sample, and the mobility is good, drainage tube nursing main points: and the drainage liquid quantity, color and character are observed, and the drainage is kept smooth.

An abdominal cavity (made of silica gel) drainage tube which is placed conventionally in an operation is easy to block due to the small tube diameter (18-24 Fr). Infectious body fluid is retained after blockage, local necrosis and abscess are formed, and infected matters can corrode to aggravate digestive tract fistula and even cause bleeding risk. Infectious effusion cannot be discharged, and necrotic substances in the drainage tube are blocked. The clinical nurse state of an illness observes that the drainage liquid is turbid, should in time report the person in charge doctor, carries out the mode that bedside gimmick washes and last lavage combines together, dredge the drainage tube, avoids the drainage tube to block up, or makes the drainage tube rethread that has blockked up, otherwise may lead to serious consequence. The necrotic substances are not easy to wash away, and the washing takes long time and is laborious. The water inflow and the water outflow are theoretically balanced, and by means of the PICC flushing theory, the pulse flushing pipe is adopted, the pulse flushing pipe is pushed and stopped, and a vortex is formed in the catheter, so that residues in all directions in the catheter can be flushed cleanly. The necrotic tissue is washed loose and repeatedly washed for a plurality of times, and the necrotic tissue is drained. Theoretically, the necrotic tissue is flushed out, the amount of aspiration is greater than the amount of irrigation, and the scale on the drainage bag is recorded. And observing the drainage liquid amount of the drainage bag. Indicating that the flush was effective. When the drainage tube is washed, the switch of the infusion apparatus is completely opened, water in the Murphy's dropper flows linearly, spiral annular or banded water flow is seen in the drainage tube, the flow is correspondingly increased, more dark drainage liquid or floccule and tissue blocks are washed out along with the drainage liquid, and then the drainage liquid is cleared along with the drainage liquid, and necrotic objects are discharged discontinuously. Note that if the infusion solution is released and still drops like water drops, the water inflow is not smooth. Under the drive of continuous water flow and negative pressure, digestive juice and necrotic tissues can be discharged as soon as possible, thereby creating conditions for wound healing; so the unobstructed drainage is particularly important for treating the severe acute pancreatitis; however, the existing abdominal cavity irrigation adopts an infusion apparatus and a drainage bag for irrigation, and the device has some problems or defects, firstly, the aseptic state can not be kept in the irrigation process, secondly, the traditional abdominal cavity irrigation is time-consuming, medical staff needs to bend down for a long time for operation, the workload is large, and generally 1-2 hours are needed for completing the irrigation of one patient in the whole process.
