WEILI Computerized Ascites Dialytic Ultra-filtration & Reinfusion System

WLFHY-500 TYPE
WEILI Computerized Ascites Dialytic Ultra-filtration & Reinfusion System

Ascites is one of the most familiar complications of Hepatocirrhosis. The formation mechanism of ascites is complicated. Once there is ascites, it will cause infection in the abdominal cavity and it is hard to cure by traditional treatment. In order to alleviate the patient’s tremendous pain caused by the soaring increase of intra-abdominal pressure, doctors always do abdominal paracentesis. However, paracentesis will bring about the decrease of plasma colloid osmotic pressure due to great loss of protein. So there will be more and more ascites. This vicious circle will aggravate the symptom in turn.

WLFHY – 500 WeiLi Ascites Ultrafiltration & Concentration Reflux System produced by Beijing WeiLi New Century Technology & Science Development Co.Ltd. can filtrate extra ascites, some electrolyte, endotoxin etc. and infuse the concentrated albumin, macrophage, complement C3, etc. back into abdomen or vein according to clinical situation. Nowadays, the plasma products are very expensive, with this new treatment method, we can not only cure the symptoms of ascites more effectively but also reduce treatment cost and increase safety for patients.

Therapeutic Principles
   
 
Therapies (flow charts)

Infuse concentrated ascites back to abdomen

Through this trerapy, the albumin concentration of ascites in abdomen is increased, then the ascites is infused back to blood vessel via three absorption ways:

enhance phagocytic function of peritoneal cells
enhance absorption function of lymphatic vessels
increase dynamic exchange between ascites and visceral blood.

Concequently, the albumin concentration in plasma is raised and the body effective blood volume is increased. As a result, the blood flow in kidney is improved and there is more urine so as to prevent liver and kidney syndrome.

 

Indication:

to filtrate extra ascites and filtrate same amount of K+, Na+, Cl- and some endotoxin so as to improve retention of water and sodium and electrolyte disorder.
to recollect albumin, macrophage, complement C3, so as to prevent abdomen infection
concenquently, to reduce ascites, abdominal pressure and abdominal distension so as to improve respiration difficulty, raise appetite and improve mental state
to be widely used in all kinds of excessive ascites caused by various reasons with simple operation and reliable safety.

Infuse concentrated ascites back to vein

When the ascites is absolutely free from infection, the repeatedly concentrated ascites is infused back into vein so as to increase plasma colloid osmotic pressure directly and increase body effective blood volume.

Indication:

To be used when ascites is leakage liquid and ascites endotoxin is negative
To increase plasma albumin concentration directly in short time
To save plasma products and avoid blood infection

Double ascites filtration and reflux

For those cancer ascites, infectious ascites and endotoxin ascites, since there is a lot of bacteria, cancer cell and endotoxin, infusing these ascites back to abdomen will bring about proliferation of cancer cell, hematosepsis, disseminated intravascular coagulation and deteriorated liver and kidney function. It is recommended to use fractioner to separate bacteria, endotoxin and cancer cell, blood cell and other large molecule and then concentrate the ascites containing albumin and other medium, small molecule. It is very safe to infuse the concentrated ascites back in to patient.

Indication:

To be used for cancer ascites, bloody ascites, seriously infectious ascites
To remove bacteria, cancer cell and blood cell in ascite

Characteristics:
   
Two pumps design to ensure accurate outflow/inflow of acsites and outflow of waste liquid
Photo-electronic design to ensure operationor’s safety when pumps are working
Computer program to control whole treatment automatically,
Easy pressure and heart rate test to ensure patient’s safety during treatment
   
Specific Disposables

Our disposables are designed to reduce medical staff work and to ensure patient’s safety.

The high-volume filtrator ensures efficient filtration and removes some endotoxin and bilirubin in ascites
In the course of filtrating ascites by molecular sieve, there might appear some fibrin deposit which can cause immunoreaction. Therefore, the sieve in the pipeline is designed to avoid deposit from entering abdomen and to ensure the patient’s safety
The two abdomen puncture needles are both trocars. The soft casing is to prevent soft issue injury such as intestinal wall injury when moving the needle. There are eight holes designed at the wall of trocar used to take out ascites so as to avoid needle block due to taking ascites of high concentration.
