The specific embodiment:
Specific embodiment:
See figures.1.and.2, present embodiment comprises tank body 1, inner cap 2, enclosing cover 3, inner cap 2 be located among the jar mouthful 1-1 of tank body 1 and with the inwall of jar mouth 1-1 between closely be connected; Closely is connected between the outer wall of described enclosing cover 2 and jar mouthful 1-1 and inner cap 2 is sealed; The cross section of described inner cap 2 is " recessed " font, on the diapire of inner cap 2, be provided with the conduit 2-2 that is communicated with tank inner chamber, the upper end 2-2a of conduit 2-2 be arranged in inner cap 2 cavity 2-1 in, the lower end 2-2b of conduit 2-2 interts in tank body 1 inner chamber, and the top of described enclosing cover 3 is provided with the protruding chamber 3-1 that projects upwards; The cavity 2-1 of described inner cap 2 and the protruding chamber 3-1 of described enclosing cover are communicated with, form the spatial accommodation of a sealing; In spatial accommodation, be provided with an elastic tube 4, the end sealing of described elastic tube 4, its other end is sealedly and fixedly connected with the conduit upper end 2-2a that is arranged in cover cavity.
In the present embodiment, described elastic tube 4 internal diameters size is identical with the external diameter size of the pipette 5 of haemodialysis control unit.Described conduit 2-2 and inner cap 2 structure that is formed in one.Adopt between the outer wall of described enclosing cover 2 and jar mouthful 1-1 and be threaded.Clamping or be threaded between the inwall of described inner cap 2 and jar mouthful 1-1.On inner cap 2, be positioned at the cavity opening and be provided with annular lip 2-3.Top at tank body 1 also is provided with handle 1-2.
With reference to Fig. 3, open enclosing cover during use, the elastoplast pipe that covers in vising with mosquito forceps, respectively the pipette of dialysis machine is inserted the bottom of the tank inner chamber of closed bicarbonate hemodialysis jar then, make dialysis flow container and dialysis machine connect into a closed dialysis system, so both can prevent CO
2Overflow, prevent the dialysis solution in the external liquid contamination jar again.
The hemodialysis jar that present embodiment relates to can seal deposits the bicarbonate blood dialysis solution, also can carry out under airtight environment in use simultaneously, can prevent CO
2Effusion and dialysis solution are contaminated, and it also has good sealing effect simultaneously, and transfusion speed is fast, stable, and volume is big, and cracky is not convenient to the characteristics of transporting and storing.
The present invention and open hemodialysis are compared, have following difference effect:
1, closed and open hemodialysis front and back blood gas analysis, the result shows PH, HCO
3-, BE all has difference significantly.
2, the blood oxygen pressure more preceding obvious decline of open treatment patient after saturating, and the horizontal no difference of science of statistics of blood oxygen pressure before and after the closed hydrocarbonate dialysis.
3, biochemistry detection before and after the dialysis, two kinds of method curative effects do not have big-difference, but that the clinical response closed is better than is open.Because the effect of closed is better than open, so improved the patient quality, patient is ready to accept the treatment of this mode, improve the quality of dialysis treatment, attract more patients to accept this bicarbonate hemodialysis, so the existing good economic benefit of this treatment also has good social benefit.
Application example one:
Multitude's money capital, woman, 73 years old.Because of diabetic nephropathy, the maintenance hemodialysis treatment, in January in this year because of digestive tract hemorrhage, merge the severe acidosis in center ICU treatment,, and adopt the treatment of closed bicarbonate maintenance hemodialysis jar simultaneously through center ICU medical treatment, remission, stopped bleeding is changeed public ward from center ICU, has now left hospital and has continued hemodialysis in outpatient service.
Application example two:
Lin Jiyu, man, 82 years old.Because of diabetic nephropathy, the capable peritoneal dialysis of chronic renal insufficiency 2 years this time is admitted to hospital because of cerebral infarction.Anuria, high potassium, stupor appear after being admitted to hospital, the critical ICU that goes to of the state of an illness.The bedside closed of in medical treatment, changing one's profession bicarbonate hemodialysis jar treatment, once a day, treat 7 times altogether after, change per two days into once.Patient's state of an illness transfers to stable after treating.
Application example three:
Li Hongjun, man, 85 years old.Because of chronic nephritis, renal insufficiency uremia row maintenance hemodialysis treatment 5 years.Look into the preceding HCO of dialysis
3 -: 21.6mmol/L, BE:2mmol/L adopts the treatment of closed bicarbonate hemodialysis jar, dialysis back HCO
