Abstract

The utility model discloses a novel macromolecular microballoon adsorbing column which comprises a column body, screen supports, silica gel cushions, end covers and a cover cap, wherein the column body can contain microballoon adsorbing agent; filtering screens are fixed on the screen supports which are mounted at two ends of the column body; the silica gel cushions are cushioned on the screen supports; the end covers are provided with Luer connectors and are used for tightly screwing the silica gel cushions and the screen supports at the two ends of the column body; the cover caps are used for sealing the Luer connectors; the screen supports and the filtering screens are integrally formed by injection-molding; and the end covers at the two ends are respectively provided colors so as to differentiate an artery from a vein. In the adsorbing column, the screen supports and the filtering screens are integrated through injection-molding, therefore, the production flow is simplified, molds needed for production are reduced, the production efficiency is improved, and the cost is lowered; the end covers at the two ends of the adsorbing column differentiates a blood path pipe arterial connector from a blood path pipe veinal connector by colors, therefore, error operations are prevented, and the safety in a process of using the novel adsorbing column is strengthened; and the product has good sealing performance, therefore, the phenomenon of liquid leakage does not occur in the moist-heat sterilizing process.

Description

Novel high polymer microsphere adsorption column

Technical field

This utility model relates to blood purification apparatus technical field, relates in particular to the polymer microsphere adsorption column.

Background technology

Hemoperfusion is by cardiopulmonary bypass unit, blood is introduced be equipped with in the polymer microsphere adsorption column of solid adsorbent, by some blood purification method exogenous or the endogenous poisonous substance in the adsorbent removing blood.This method has been widely used in the detoxifcation of medicine and chemical toxicant, uremia, treatment of diseases such as hepatic encephalopathy and autoimmune disease at present clinically.The polymer microsphere adsorption column comprises the cylinder that its inside can ccontaining microsphere adsorbing agent, be fixed with filter screen on it and rack that be installed in the cylinder two ends, pad is contained in the silicagel pad on the rack, which is provided with female Luer and silicagel pad and rack are tightened on the end cap at cylinder two ends, adorn different adsorbents in the cylinder and can play different therapeutic effect, the disposable use charcoal kidney that with the active carbon is adsorbent is mainly used in the poisoning first-aid field, be that the disposable use resin absorption post of adsorbent is mainly used in during the renal failure patient removes with the resin, macromole poisonous substance field is that the disposable use resin anion (R.A.) blood plasma adsorption column of adsorbent is mainly used in the liver disease field with the resin anion (R.A.).Employed clinically at present polymer microsphere adsorption column, rack and filter screen be connected the mode that generally adopts welding, welding manner can produce many flying chips in welding process, flying chip drops on the filter screen, in case it is very big to human body harm to enter blood, and the production procedure of this kind welding manner is comparatively complicated, and production efficiency is low; And, the end cap at cylinder two ends, not with the sign of clear and definite color as tremulous pulse and vein interface, in the hemoperfusion field, these all are vital problems.

The utility model content

The technical problems to be solved in the utility model provides a kind of need not and welds, and has the novel high polymer microsphere adsorption column of the sign of clear and definite tremulous pulse and vein interface.

The technical scheme that adopts for solving the problems of the technologies described above: a kind of novel high polymer microsphere adsorption column, comprise cylinder that its inside can ccontaining microsphere adsorbing agent, be fixed with filter screen and rack that be installed in the cylinder two ends on it, pad is contained in silicagel pad on the rack, which is provided with female Luer and silicagel pad and rack be tightened on the cylinder two ends end cap, be used for the block of capping female Luer.Described rack and filter screen are integrated injection molding, also have the end cap at two ends to be set as respectively to show that differentiation connects tremulous pulse and venous color.

After adopting this utility model, be integrated injection molding, simplified production procedure, reduced required mould in the production, enhance productivity, reduce cost because rack and the connected mode of filter screen take; The end cap at adsorption column two ends is distinguished blood vessel tremulous pulse and vein joint with color, prevents operate miss, strengthens its safety in use; Product hermeticity can be good, in the moist heat sterilization process, the phenomenon of leakage can not occur.

Description of drawings

Fig. 1 is the cross-sectional view of this utility model novel high polymer microsphere adsorption column.

The specific embodiment

As shown in Figure 1, a kind of novel high polymer microsphere adsorption column, comprise cylinder 1 that its inside can ccontaining microsphere adsorbing agent, be fixed with filter screen 2 and rack 3 that be installed in the cylinder two ends on it, pad is contained in silicagel pad 4 on the rack 3, which is provided with female Luer 51 and silicagel pad 4 and rack 3 be tightened on cylinder 1 two ends end cap 5, be used for the block 6 of capping female Luer 51.Wherein rack 3 and filter screen 2 are integrated injection molding, also have the end cap 5 at two ends to be set as respectively to show that differentiation connects tremulous pulse and venous color.

Claims

1. novel high polymer microsphere adsorption column, comprise cylinder that its inside can ccontaining microsphere adsorbing agent, be fixed with filter screen and rack that be installed in the cylinder two ends on it, pad is contained in silicagel pad on the rack, which is provided with female Luer and silicagel pad and rack be tightened on the cylinder two ends end cap, be used for the block of capping female Luer, it is characterized in that: described rack and filter screen are integrated injection molding, also have the end cap at two ends to be set as respectively to show that differentiation connects tremulous pulse and venous color.
