Abstract
The utility model provides a medical double filter, which consists of a filter with a filtering net and an ultrafilter with an ultrafiltration membrane. The place below the ultrafilter and above the filter, and the place at the bottom and the upper part of the ultrafilter are respectively provided with two blood inlets; the middle part of the ultrafilter is provided with a water filtering gap, and the inlet of the ultrafilter is communicated with the ultrafiltration membrane cavity; moreover, the lower part of the filter is provided with a blood outlet, and an air exhaust and pressure measuring gap are arranged above the ultrafilter. The double filter has advantages of simple operation and convenient operation; at the later period of extracorporeal circulation, the utility model, which assists the circulation while filtering water for concentrating the blood, can filter the redundant water in body in a short time, thereby being economical and practical.
Description
The double filter that extracorporeal circulation was used when this utility model related to a kind of operation on heart.
Concentrate blood is got rid of the method for moisture in the body in the extracorporeal circulation at present, except that diuretic and change-blood (at present without this method), also has ultrafiltration.
Be artificial kidney or ultrafilter or art to be installed finish in extracorporeal circulation mostly, but these operations are more loaded down with trivial details, easily cause pollution, and can cause operating time to prolong, increase surgical risk with modified ultrafiltration method drainage.
The purpose of this utility model provides the double filter of limit assist circulation a kind of simple to operate, easy to use, limit drainage concentrate blood.
The purpose of this utility model is achieved in that it is made up of filter that has drainage screen and the ultrafilter that has a ultrafilter membrane, ultrafilter below, filter up, be respectively equipped with two on ultrafilter bottom and top and go into the blood mouth, be provided with the drainage mouth at the middle part of ultrafilter, the import of filter is communicated with the ultrafilter membrane chamber, and the bottom of filter is provided with blood outlet, and the top of filter is provided with the aerofluxus pressure tap.
This utility model compared with prior art has following advantage:
1. dual-use function: filtered air, embolus are arranged in extracorporeal circulation, have the dual-use function of ultrafiltration water, concentrate blood simultaneously again concurrently.
2. simple to operate, easy to use.
3. CPB time and loaded down with trivial details modified ultrafiltration step can be obviously reduced, fund (modified ultrafiltration device and parts price are thousands of units) can be saved again.
4. can at short notice patient blood be concentrated, it is stable to keep hematodinamics.
5. especially the renal insufficiency person is had more clinical meaning.
Below in conjunction with drawings and Examples this utility model is further described.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, double filter is made up of filter 1 that has drainage screen 11 and the ultrafilter 2 that has ultrafilter membrane 12, filter 1 up, ultrafilter 2 below, the below of ultrafilter 2 and top are respectively equipped with into blood mouth 3,4, to go into blood mouth 3 and be communicated with ultrafilter membrane chamber 6 by passage 5, the ultrafilter middle part is provided with drainage mouth 7, the import 8 of filter 1 is communicated with ultrafilter membrane chamber 6, the bottom of filter 1 is provided with blood outlet 9, and the top of filter 1 is provided with aerofluxus pressure tap 10, during dilute blood, water is housed in the ultrafilter, blood enters double filter from going into blood mouth 3, through filtering exhaust, comes out from blood outlet 9, blood runs out of, and can directly advance blood from going into blood mouth 4; When moisture was got rid of in the body in extracorporeal circulation, concentrate blood, blood entered double filter to go into blood mouth 3, simultaneously from drainage mouth evacuation; Because the moisture in the effect blood of ultrafilter membrane 12 is filtered off, through filter 1 air embolus is filtered, through air vent 10 air to be discharged, the blood of purification flows out from blood outlet 9.
