Abstract
The utility model provides an extracorporeal circulation ascites ultrafiltration device which belongs to the medical instrument technical field and structurally comprises an abdominal cavity drainage tube, a catheter and an ultrafilter; the abdominal cavity drainage tube is connected with the catheter, a roller pump is arranged on the catheter, the catheter is sequentially connected with the ultrafilter, a pulser a resistance regulator and a spotted bubble adsorber, and the spotted bubble adsorber is connected with an injection syringe. The ultrafilter is connected with a filtrate collector. The pulser is provided with a pulse pressure gauge. The injection syringe is provided with a Murphy tube, and the rear end of the injection syringe is provided with a syringe needle. The extracorporeal circulation ascites ultrafiltration device can remove the ascites in constant speed, filter out the crystal substance with molecular weight less than 5000 Dalton and transfuse the filtrate to the patient through intravenous injection; the influence on patients is small; the extracorporeal circulation ascites ultrafiltration device has reasonable design, simple structure, is safe and reliable, is convenient in use, and realizes easy disinfection and maintenance.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of extracorporeal circulation ascites ultra-filtration device.
Background technology
General, causing the refractory ascites most important reason is the infection of portal hypertension, hypoproteinemia and ascites.Secondly, can not timely and effective adjustment diuretic also be the problem that can not be ignored with iatrogenic factors such as control sodium, water absorptions.The patient is because of a large amount of ascites, and life quality descends, the serious infection of caused ascites, hepatorenal syndrome or hepatic encephalopathy and threat to life.Thereby, implement effective Supporting Therapy and seem very important, correct treatment in time.Treatment comprises strict low salt diet, the intake (being no more than 1500 milliliters every day) of restriction water, the additional human albumin of interruption and adjusts the kind and the dosage of diuretic in good time, to keep the stable of interior environment.Conditioning just can alleviate conditions of patients between this method needed often, many clinically the direct drain of seroperitoneum was emitted, and made the run off favourable material of a lot of internal metabolisms of human body when seroperitoneum is emitted, and brought negative effect for to a certain extent patient's rehabilitation.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of extracorporeal circulation ascites ultra-filtration device is provided.
The technical solution of the utility model realizes in the following manner, this extracorporeal circulation ascites ultra-filtration device, its structure comprises peritoneal cavity drainage tube, conduit, ultrafilter, the peritoneal cavity drainage tube connecting duct, conduit is provided with the roller pump, conduit connects ultrafilter, pulser, dragulator, point-like bubble adsorber successively, and point-like bubble adsorber is connected with syringe.
Be connected with the filtrate liquid trap on the described ultrafilter.
Described pulser is provided with the pulsating pressure table.
Described syringe is provided with Murphy type tube, and the syringe end is provided with injection needle.
The beneficial effect that this utility model is compared with prior art produced is:
This extracorporeal circulation ascites ultra-filtration device can remove ascites with uniform speed, can remove molecular weight less than 5000 daltonian crystal sample materials, and feeds back once more to the patient by intravenous approach; This device can concentrate 2~4 times with the protein in the ascites, internal energy 5000 milliliters of the ascites that remove on 10 hours, and its side effect instrument is a low grade fever, and is very little to the influence that human body brings; This device is particularly suitable for liver cirrhosis patient with the renal insufficiency person, and this device can be removed carbamide and other crystal sample materials, can make the patient remove ascites gradually fast, and the reuse diuretic is consolidated its curative effect afterwards; This device adopts enclosed type sterilization loop, and further improvement has been arranged on prevention infection.
This extracorporeal circulation ascites ultra-filtration device is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to sterilization and safeguard.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Labelling in the accompanying drawing is represented respectively:
1, peritoneal cavity drainage tube, 2, conduit, 3, the roller pump, 4, ultrafilter, 5, the filtrate liquid trap, 6, pulser, 7, the pulsating pressure table, 8, dragulator, 9, point-like bubble adsorber, 10, syringe, 11, Murphy type tube, 12, injection needle.
The specific embodiment
Below in conjunction with accompanying drawing extracorporeal circulation ascites ultra-filtration device of the present utility model is done following detailed description the in detail.
As shown in Figure 1, extracorporeal circulation ascites ultra-filtration device of the present utility model, its structure comprises peritoneal cavity drainage tube 1, conduit 2, ultrafilter 4, peritoneal cavity drainage tube 1 connecting duct 2, conduit 2 is provided with roller pump 3, conduit 2 connects ultrafilter 4, pulser 6, dragulator 8, point-like bubble adsorber 9 successively, and point-like bubble adsorber 9 is connected with syringe 10.Be connected with the filtrate liquid trap on the ultrafilter 4.Pulser 6 is provided with the pulsating pressure table.Syringe 10 is provided with Murphy type tube 11, and syringe 10 ends are provided with injection needle 12.
This extracorporeal circulation ascites ultra-filtration device inserts the patient abdominal cavity with peritoneal cavity drainage tube in use, the other end inserts patient's superior vena cava with injection needle, and ascites flows into extracorporeal circulation from the abdominal cavity; Guarantee that ascites can only one-way flow.This extracorporeal circulation ascites ultra-filtration device can make that cardiac output increases by 50%~70% before the treatment, glomerular filtration rate increases by 40%, and the urine amount increases, and ascites reduces, patient's situation be improved significantly.
