Description
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of medical apparatus and instruments that is used for hemoperfusion.
In recent years, the blood purification therapy is popularized development rapidly in China, and the demand of disposable use charcoal kidney increases year by year, but external product costs an arm and a leg, as: 3000 yuan/of Sweden adsorba300c price RMB, 500 dollars/of Japanese DHP-1 prices do not meet China's national situation.At present, the domestic carbon kidney is an example with 200 types, and its tank body adopts the electromagnetic high-frequency eddy current to be welded, but because of 4 solder joints are arranged, production efficiency is low, and not plump leakage a bit occurs, and entire product is scrapped.Its blood mouth and bloody path pipeline connected mode are plug-in type, and clinical improper use meeting comes off, and causes the accident.
The purpose of this utility model is to provide that a kind of production technology is simple, efficient is high, safe and reliable, and cheap novel charcoal kidney is to satisfy the demand of domestic market.
The purpose of this utility model is realized by following technical scheme:
This charcoal kidney comprises tank body 1, adsorbent 2, and its improvements are to be embedded with filter screen 3 at the two ends of tank body 1, and filter screen 3 is provided with sealing ring 4, and tegillum 5 is placed on the sealing ring 4 fixing with gland 6.
Described tegillum 5 is provided with blood mouth 7, the sealing that spins of it and medicated cap 8.
Sealing gasket 9 is equipped with at described medicated cap 8 tops.
The gland 6 and the tank body 1 of this charcoal kidney spin fixing.
The gland 6 of described disposable use charcoal kidney is double-deck double wall.
The bottom edge of described disposable its medicated cap 8 of use charcoal kidney is provided with groove and matches with projection on the tegillum 6.
Compare with original technology, it is simple that this charcoal kidney has production technology, do not need Special Equipment, and the efficient height is convenient to promote, the suitable production in enormous quantities in enormous quantities, and safe and reliable, and lower-price characteristic, solved the demand of domestic market effectively.
Below in conjunction with accompanying drawing this utility model is described in further detail:
Accompanying drawing 1 is a half sectional view of the present utility model.
As seen from Figure 1, the tank body 1 of this charcoal kidney adopts the straight tube of circle, there is screw thread at two ends, its external diameter is identical with the dialyser external diameter, the two ends up and down of tank body 1 all are embedded with a frame drainage screen 3, and sealing ring 4 presses on drainage screen 3, then tegillum 5 are pressed on sealing ring 4, it is fixing to spin with gland 6 and tank body 1 at last, and gland 6 is double-deck double wall formula.Tegillum 5 is provided with blood mouth 7 it and medicated cap 8 and adopts the sealing that spins of the connected mode of interpolation exterior buckle types, and in the blood mouth 7 recessed gland 6 upper edge end faces, in case the blood mouth is loosening because of colliding among transporting.At the top of medicated cap 8 sealing gasket 9 is housed, its bottom edge is provided with and prevents to reverse the groove that moves back button, and it matches with projection on the tegillum 5.Adsorbent 2 in the charcoal kidney is handled the active carbon of back peplos for special process.
Because tank body 1 and tegillum 5 have adopted spiral shell to withhold cover 6 and add sealing ring 4 and screw and be connected, and the top of medicated cap 8 also is provided with sealing gasket 9, so seal point lacks than conventional art, the probability that generation is leaked gas has reduced 50%.Simultaneously, be adsorbent owing to adopt the homemade blood purification level active carbon of development newly, through after the specific PROCESS FOR TREATMENT, surface parcel modified polyvinylalcohol film, prevented microgranule release, improved blood compatibility, respectively installed one 70 order frame chinlon net in two ends up and down at tank body.This charcoal kidney is the hygrometric state fixed bed, has passed through anticoagulant and antifreeze processing, and flushing when using clinically, aerofluxus is convenient, quick, passes through 100kPa pressure testing and 115 ℃ of high temperature sterilizes again, and clinical use is safer, reliable.
