The assembling process of apparatus for purifying blood 2 is as follows:
(1) close the open-close on-off 225 on linkage unit 22, be positioned on the first side, side, connectivity port 222 at circular bulkheads 221 and place sealing plain cushion.
(2) filter screen 213 to be loaded on perfusion unit 21 adsorption column 212 away from closing component one end, and be fixed, then coordinate with to be located on the port of export 2123 externally threaded by being located at female thread on entrance point 222, be socketed on by entrance point 222 outside the port of export 2123 and be also sealedly and fixedly connected with it, the secure fit of sealing plain cushion to the two being positioned over the first side, connectivity port 222 plays sealing function.
Ground floor adsorbent is filled in (3) second filter courses 21202; Then, be connected with the buckle of the buckle 2122 be located on inside adsorption column 212 by the screens be located on filter 2121, or adopt the mode of welding to be fixed on by filter 2121 on the medial wall of adsorption column 212; Then in the second filter course 21201, second layer adsorbent is filled, the capacity of ground floor adsorbent is slightly smaller than the capacity of second layer adsorbent, make the first adsorption layer and the adsorbent that the second adsorption layer holds substantially equal along adsorption column 212 thickness axially, then closing component 211 is fixedly connected on the entrance point of adsorption column 212.Filter screen in closing component 211 and filter screen 213 are positioned at the two-port place of adsorption column 212, go out to flow out from its two-port for preventing adsorbent.
(4) side, side being positioned at the second connectivity port 223 at circular bulkheads 221 is placed sealing plain cushion, inside is accommodated dialyzer, and dialysis cartridge 231 lower end that is fixed dialyzer by adhesive linkage, two ends and end cap 232 are sealedly and fixedly connected, blood mouth 2320 is connected with block, and dialysis solution outlet 2313 and dialysis solution import 2312 are fixedly connected with cap sealed respectively.By the threaded engagement of the female thread on the external screw thread on entrance point 2310 and the port of export 223, be sealedly and fixedly connected with linkage unit 22 by the adsorption column 231 be pre-installed, the secure fit of sealing plain cushion to the two being positioned over the second side, connectivity port 223 seals.
(5) after the assembling completing apparatus for purifying blood 2, the direction along unit with dialysis 23 to perfusion unit 21 purifies apparatus for purifying blood 2, finally carries out sterilizing and packaging to whole apparatus for purifying blood again.
In storage after completing production and transportation, open-close on-off 225 is in closure state all the time, be on the one hand in case the fragment that may exist due to adsorbent in adsorption column 212 is entered on the dialyzer in dialysis cartridge 231 by filter screen 213, affect the safety and effectiveness of dialyzer.On the other hand, adsorption column 212 may be different from the storage mode of dialysis cartridge 231, and such as dialysis cartridge 231 is inner is dry state preservation, and the inside of adsorption column 212 is hygrometric state preservation, or the two is contrary, thus isolates the two inside, effectively guarantee the effectiveness used.
In use, first apparatus for purifying blood is rushed heparinization in advance, and then carry out blood purification treatment.Wherein, pre-punching can select the one in following two kinds of pre-punching methods to rush in advance:
The first pre-punching method is, along gravity direction, unit with dialysis 23 is positioned at the top of perfusion unit 21, after connecting pipeline, rush liquid in advance and enter dialysis cartridge 231 from blood mouth 2320, open open-close on-off 225, make to rush in advance liquid first to rush dialysis cartridge 231 in advance and then rush in advance through adsorption column 212 pairs of adsorption columns 212, to make in adsorption column the adsorbent fragment in 212 be rushed liquid in advance to go out from blood mouth 2110, until pre-punching to meet treatment require time, apparatus for purifying blood 2 is turned, make the blood mouth 2110 of perfusion unit 21 upward, and then rush in advance, thus contribute to the thorough emptying of bubble of perfusion unit 21 inside, effectively avoid adsorbent fragment to enter in dialysis cartridge 231 simultaneously, affect the dialysis function of dialysis cartridge 231, improve the safety in utilization of apparatus for purifying blood.
The pre-punching method of the second is, along gravity direction, unit with dialysis 23 is positioned at the below of perfusion unit 21, treat to fill in dialysis cartridge 231 rush liquid in advance after open open-close on-off 225, rushing liquid in advance enters dialysis cartridge 231 from blood mouth 2320, then by adsorption column 212, the two is rushed in advance, the liquid that rushes in advance in adsorption column 212 is effectively avoided to reflux in dialysis cartridge 231 under gravity, adsorbent fragment is also brought into the dialysis function affecting dialyzer in dialysis cartridge 231, and this pre-punching method can make the quick emptying of bubble of perfusion unit 21 inside.
In the present embodiment, adsorption column 212, sleeve 220, through hole 224 and dialysis cartridge 231 coaxial arrangement.In order to make the pressure in perfusion unit 21 inside and unit with dialysis 23 inside maintenance safety range, and blood flows through through hole 224 with increasing without pressure, the diameter of through hole is more than 4 millimeters, is preferably 4 millimeters to 10 millimeters, reduces blood in apparatus for purifying blood 2, occurs blood coagulation, haemolysis equivalent risk.
Because blood is to the effect of adsorbent generation viscosity, adsorbent extrudes towards a direction along with blood flow, and under blood viscous effect, occur that gathering is united phenomenon, thus the damping force improved blood flow, the increase of blood flow promotes gathering to unite phenomenon further, the blood flow in adsorption column 212 is caused to be difficult to further raising, and the present embodiment uses filter the filter chamber 2120 of adsorption column 212 to be separated into two along Blood index post 212 filter course that axially adsorbent thickness is substantially equal, occur that gathering is united effect to reduce over the agent of filter chamber internal adsorption, under the basic prerequisite improving safety, improve the maximum permissible value of blood flow in adsorption column 212.The diameter of the mesh of filter 2122 is 200 microns to 600 microns, is preferably 300 microns to 500 microns.Adsorbent can be of the same race or multiple adsorbent composition.
Adsorbent capacity in adsorption column 212 is 20 milliliters to 600 milliliters, and be preferably 20 milliliters to 130 milliliters, in dialysis cartridge 231, the area of dialyzer is 1.2 square metres to 2.0 square metres.
When the capacity of every layer of filter course is less than 20 milliliters, can further improve the blood flow in the unit interval in adsorption column 212.
