Description
Technical field
This utility model belongs to medical supplies, relates to a kind of medical apparatus and instruments, especially a kind of medical apparatus and instruments that is used for hemoperfusion.
Background technology
In recent years, the blood purification therapy is popularized development rapidly in China.Hemoperfusion is the important component part of blood purification, because the employing and the improvement of active carbon coated fertilizer, and the succeeding in developing of various special resins, it is clinical that blood perfusion technique is widely used in, not only serious symptom poisonous substance, drug intoxication there is good curative effect, and nowadays also can be used for the treatment of many chronic, intractable and the difficult disease of human body and animal, and convenient, directly, quick.The demand of disposable blood perfusion device increases year by year.
At present, the domestic and international blood perfusion device of producing, its cylinder adopts the technology of ultra-sonic welded (U.S., Sweden) or eddy current welding (Japan) more, but because of a plurality of solder joints are arranged in the welding process, production efficiency is low, and in a single day careless mistake a bit appears, entire product will be scrapped.Its blood mouth mostly is straight V shape, in case blood coagulation or arterial end resistance are big, easily cause and collapses out; Blood mouth and bloody path pipeline connected mode are plug-in type, and clinical improper use meeting comes off, and easily causes the accident.
The purpose of this utility model is to provide the blood perfusion device that a kind of production technology is simple, efficient is high, safe and reliable, to satisfy the needs in market.
Summary of the invention
The purpose of this utility model is realized by following technical scheme:
The design's disposable hemoperfusion with activated carbon device, comprise cylinder 1 and adsorbent 2, the blood of cylinder 1 is imported and exported two ends and is embedded with filter screen 3, is withholding rubber seal 4 on the filter screen 3, end cap 5 rotations are fixed on the sealing ring 4, import and export two ends with tegillum 6 sealings and unlatching.Center projections in the described end cap 5 becomes the rounded breasts shape, forms blood mouth 7 and blood mouth overcoat 8, in the blood mouth overcoat 8 screw thread is arranged; The inwall of the base portion of rounded breasts shape and end cap 5 forms an annular ditch, and the annular ditch bottom is pressed on the sealing ring 4.Described tegillum 6 is the softish PP plastics of medical grade, and the peripheral hardware screw thread is harmonious with blood mouth overcoat 8 female thread negative and positive, and there is projection in the central authorities of tegillum 6, and the size and blood mouth 7 internal diameters of projection are harmonious.End cap (5) is fixing for spinning with cylinder (1).The wall 10 of cylinder 1 is thin at the blood inlet end, and is gradually thick to port of export extension, forms conical internal cavity, and conical internal cavity is expanded into a cylindrical blood chamber 11 at the port of export.
The total measurement (volume) that described conical internal cavity and cylindrical blood chamber 11 form is 250 ± 10 milliliters.
Described filter screen 3 employing apertures are 200 microns polypropylene screen cloth, and heat seal is on the PC plastic ring.
Described adsorbent 2 is a cylindricality hemoperfusion level active carbon, with polyvinyl alcohol and collodion peplos.
Compare characteristics such as the design's perfusion utensil has production technology simple, does not need Special Equipment, and the efficient height can be mass-produced, and is safe and reliable with original technology.As adopt the high-quality raw material of external import and advanced person's production technology, technology, can further guarantee safety of the present utility model.
Description of drawings
Fig. 1 is a three-dimensional half sectional view of the present utility model;
Fig. 2 is tegillum 6 and blood mouth overcoat 8 generalized sections;
Fig. 3 is end cap 5 and sealing ring 4 generalized sections;
Fig. 4 is wall 10 and cylindrical blood chamber 11 generalized sections.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
As seen from Figure 1, the cylinder 1 of this hemoperfusion with activated carbon device adopts the straight tube of circle, and it is imported and exported two ends and all is embedded with a frame drainage screen 3, and rubber seal 4 presses on filter screen 3, spins fixing with end cap 5 and cylinder 1 then.Establish an annular ditch in the end cap 5, along with the end cap backspin, can make rubber ring 4 from top to down, evenly stressed from inside to outside, and with end cap and cylinder close proximity, guarantee can not leak.Center projections becomes the rounded breasts shape to form blood mouth 7 in the end cap 5.From the sealing that spins of the visible blood mouth of Fig. 2 overcoat 8 and screw thread on the tegillum 6, and the projection at tegillum 6 tops has guaranteed the sealing property of whole perfusion device just in the embedding blood mouth.Wall 10 upper-thin-lower-thicks of cylinder 1 as seen from Figure 4, make the blood chamber of cylinder 1 inner chamber tapered, blood flow through the time pressure disperse to some extent gradually to reduce, cylindrical blood chamber 11 in lower port, make the cross-sectional sizes at cylinder 1 import and export two ends identical, in order to avoid the exit filter screen is excessive because of area reduces pressurized, cushioning effect has been played to the blood of flowing through in this cylindrical blood chamber simultaneously, and makes blood guarantee the safety of using at this mix homogeneously.Adsorbent 2 in the perfusion device is the hemoperfusion level cylindricality active carbon of import, via polyvinyl alcohol and collodion peplos.This active carbon is a pore type, do not adsorb medium molecular substances such as heparin, thrombin, and blood compatibility is good behind the peplos, so use safety and reliability.
Cylinder sheathing material of the present utility model adopts import medical grade Merlon, 121 ℃ of high temperature sterilizes of this macromolecular material tolerance, and transparency is better; Tegillum 6 adopts the softish PP plastics of medical grade.Adopt screwing type to connect between each parts, do not need welding machine special, can be mass-produced.3 of end cap 5 and filter screens are by rubber seal 4 chuckings (Fig. 3), good seal performance; The fastening that spins of screw thread that tegillum is outer and blood mouth overcoat; The blood mouth is difficult for collapsing out for revolving V shape, can be complementary with all both at home and abroad artificial kidney machine and blood vessel; Blood mouth and blood vessel adopt spiral shell to link and connect difficult drop-off; Filter screen adopts the import polypropylene net; Blood mouth and tegillum adopt built-in, prevent clashing and breaking.
Because cylinder 1 usefulness spiral shell end of thread lid 5 adds sealing ring 4 and screws connection, and the top projection 9 of tegillum 6 also played the effect of sealing gasket, so the probability that takes place to leak gas reduces greatly.The unique design of blood chamber shape has reduced the suffered pressure of exit filter screen, has prevented that effectively filter screen is out of shape because of pressurized is excessive even breaks, and exit blood homogeneous comparatively, and it will be more safe and reliable using.Simultaneously, be adsorbing medium owing to adopt the hemoperfusion level cylindricality active carbon of import, after handling through specific processes, the pure and mild collodion membrane of modified polyethylene has been wrapped up on the surface, has prevented the release of microgranule, has improved blood compatibility.The import polypropylene net of aperture 200 μ m has respectively been installed at two ends about cylinder.
This hemoperfusion with activated carbon device is the hygrometric state fixed bed, passed through anticoagulant and antifreeze processing, flushing when using clinically, exhaust and convenient, quick pass through high-potting and high temperature sterilize again, clinical safe in utilization, reliable, be applicable to multiple treatment of diseases of human body and animal and animal model test.
