Description

Dialysis device convenient to use for hemodialysis of nephrology department of hospital

Technical Field

The invention belongs to the technical field of hemodialysis, and particularly relates to a dialysis device convenient to use for hemodialysis in nephrology department in a hospital.

Background

After the renal failure phenomenon occurs, the renal function declines to enter the uremia stage, which is divided into acute renal failure and chronic renal failure, wherein the acute renal failure refers to the condition that the physiological function of the kidney is sharply reduced or even lost due to various reasons, and then a series of physiological changes are caused. Chronic renal failure refers to chronic progressive renal parenchyma damage caused by various causes, resulting in significant atrophy of the kidney, failure to maintain its basic function, and in severe cases even death of the patient.

Hemodialysis is one of the kidney replacement treatment modes of patients with acute and chronic renal failure. The method comprises the steps of draining blood in vivo to the outside of the body, enabling the blood and electrolyte solution (dialysate) with similar body concentration to be inside and outside one hollow fiber through a dialyzer consisting of a plurality of hollow fibers, and carrying out substance exchange through dispersion, ultrafiltration, adsorption and convection principles, so as to remove metabolic waste in the body and maintain the balance of electrolyte and acid and alkali; at the same time, the excess water in the body is removed, and the purified blood is returned to the patient.

The dialyser can be reused after being used for reducing the treatment cost of a patient and adopting a high-quality dialyser as far as possible, the reused dialyser can be reused after procedures such as flushing, backflushing, detection and the like, the number of times of reuse is generally 14-15 times after the connector is cleaned by dialysis, the existing dialyser can play a good dialysis function, but the flushing water pressure and the flushing flow rate of the existing dialyser during reuse have strict requirements, so that the hollow fibers are broken frequently due to overlarge pressure during reuse, and the number of times of reuse cannot be intuitively known through the device.

Need design a dialysis device for hemodialysis of hospital nephrology dept convenient to use in order to solve above-mentioned problem to above circumstances.

Both sides on 1 top of cerini dialyser cerini main part all vertical fixedly connected with dislysate mouth 6, the top of dislysate mouth 6 all is provided with external screw thread 13, is connected with blood on the left fixed connector 2 of cerini dialyser cerini main part 1 and washes connector 7.

Blood washes connector 7's inside has been seted up first logical chamber 10 from a left side to the right side in proper order, second leads to chamber 11 and third through cavity 12, and first logical chamber 10, second leads to chamber 11 and third through cavity 12 and is linked together, first logical chamber 10, the diameter that second leads to chamber 11 and third through cavity 12 enlarges from a left side to the right side in proper order, the flush fluid gets into blood washes connector 7, the flush fluid gets into first logical chamber 10 earlier, then get into second in proper order and lead to chamber 11 and third through cavity 12 in, the inside diameter of blood washes connector 7 enlarges in proper order, the velocity of flow of flush fluid has been reduced.

Blood washes right-hand member fixedly connected with adapter sleeve 9 of connector 7, thread fixed mounting is passed through in fixed connector 2 in the outside of adapter sleeve 9, blood washes connector 7 and keeps away from the one end fixedly connected with flushing pipe 8 of cerini dialyser cerini main part 1, be connected with dialysis cleaning connector 14 through external screw thread 13 on the dislysate mouth 6 on the 1 top right side of cerini dialyser cerini main part, the middle department of dialysis cleaning connector 14 inside has seted up into liquid mouth 18, go into the inside decompression reset plate 16 of having placed of dialysis cleaning connector 14 on liquid mouth 18 top, the diameter of 16 bottoms of decompression reset plate is the same with the diameter of going into liquid mouth 18 inboards, the equal fixed mounting in both sides of 16 bottoms of decompression reset plate has reset spring 17, reset spring 17's the equal fixed mounting.

The pressure reduction reset plate 16 comprises a main plate body 161, a liquid outlet groove 162 and a sliding block 163, wherein the sliding block 163 is fixedly installed at two ends of the main plate body 161, the liquid outlet groove 162 is uniformly formed in the main plate body 161, the sliding grooves 15 are formed in the inner walls of the dialysis cleaning connectors 14 at two sides of the external threads 13, the sliding blocks 163 are all slidably installed in the sliding grooves 15, the sliding block 163 and the sliding grooves 15 form a sliding structure, after the dialysis cleaning connectors 14 are in threaded connection with the external threads 13, in the subsequent disinfectant adding and washing process, washing liquid can pass through the liquid outlet groove 162 on the pressure reduction reset plate 16 and pass through the liquid inlet 18 to enter the dialyzer main body 1 for washing through the dialysate outlet 6, when the water pressure is too high, the supporting force provided by the reset spring 17 is not enough to support the pressure reduction reset plate 16, the pressure reduction reset plate 16 is pressed down, the bottom end of the pressure reduction, the flow choking effect is achieved, and the phenomenon that the hollow fiber is broken due to overlarge water pressure is avoided.

The working principle is as follows: when the dialyzer is used, a worker writes the name of a patient on the name sticker 42, checks one partition on the reuse number label 43 before each use and records the name as one time, the worker can visually observe the reuse number of the dialyzer through the reuse number label 43 after each reuse, and the dialyzer is discarded when the reuse number reaches 14 or 15 times.

And when washing the during operation to the cerini dialyser cerini, when needs wash blood side, through connecting blood washing connector 7 on the fixed connector 2 with 1 left end of cerini dialyser cerini main part, and add the antiseptic solution through 8 sides of wash pipe and wash, at the washing in-process, the flush fluid gets into blood washing connector 7, the flush fluid gets into first logical chamber 10 earlier, then in getting into second logical chamber 11 and third logical chamber 12 in proper order, 7 inside diameters of blood washing connector enlarge in proper order, the velocity of flow of flush fluid has been reduced.

When needing to wash the dislysate side, through washing the back on connector 14 threaded connection is gone up to the external screw thread 13 with the dialysis, in the follow-up antiseptic solution that adds washing process, flush fluid accessible decompression resets drain tank 162 on the board 16 and passes into liquid mouth 18 and get into dialyser ware main part 1 inside through dislysate mouth and wash, and when water pressure was too big, the holding power that reset spring 17 provided was not enough when propping up decompression reset board 16, decompression reset board 16 was pushed down, 16 bottom that reset board that reduces pressure inserts into liquid mouth 18, seal income liquid mouth 18, the choked flow effect has been played, the too big hollow fiber's that leads to of water pressure phenomenon of breaking has been avoided.

And when needs were disinfected, the accessible pasted 44 with first magic and 45 separations of second magic to pull down mark sleeve 4 from cerini dialyser cerini main part 1, can put into formalin with cerini dialyser cerini main part 1 whole after that and disinfect, after the disinfection is accomplished, again with mark sleeve 4 install back can, spacing frame 3 has then played spacing effect, avoid mark sleeve 4 to rock.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
