Blood filtration structure of dialysis machine

The present invention is a blood-splitting structure of a dialysis machine, in particular, a pre-structure for a dialysis machine to save blood dialysis time and improve blood filtration efficiency.

Kidney dialysis is the function of the kidney for some reason. It is necessary to use other methods to perform the alternative work. The traditional dialysis principle uses a needle to drain the blood from the arterial end, and the blood is washed by the artificial kidney, and the blood is washed by another needle. Flow back to the body; hemodialysis patients must be dialysis 2 to 3 times a week, 4 to 5 hours each time, can discharge excess water and urinary molecules in the blood.

However, the traditional dialysis machine has only one blood filtering mechanism, and its function is to extract the blood from the artery into the blood filtering mechanism and then return it to the patient to complete the hemodialysis of a single cycle. Single-cycle dialysis does purify the blood; such a blood filtration process not only takes a long time, but the degree of purification is often used multiple times by a single filter cartridge. The elimination of viruses and bacteria is quite limited and cannot achieve the desired performance. There are flaws in the disease.

The purpose of the present invention is to provide a blood-slipping structure of a dialysis machine, which is mainly connected to the anterior segment system of the dialysis machine, and uses a shock plate to provide a high-pressure impact of blood inflow into the tube to cause bacteria in the blood. And the blood is separated, and the poison gas is discharged; the bacteria and the blood are separated from the blood and can be dispersed into the bacterial colony cluster in the filter cartridge, and the bacteria are shocked through the filter cartridge to allow the bacteria to gather. In the bacterial colony set in each layer, the number of bacteria in the blood is minimized, and the blood after separation and purification is drained to the patient body, thereby reducing the number of dialysis and saving the blood dialysis time.

In order to achieve the above object, the blood filtration structure of the dialysis machine disclosed in the present invention comprises a filter cartridge, an impact plate disposed in the filter cartridge, and a plurality of layers of blood filter plates provided with a bacterial cluster; wherein the impact plate corresponds to The blood drainage port is arranged, and the surface of the plate is provided with a zigzag shape; the plurality of blood filter plates are layered, and the upper end faces thereof are respectively provided with bacterial colonies for bacterial accumulation, and the arrangement of the bacterial colonies is more loose tissue. Gradually set up for the fine tissue, and the blood filter plate is provided with a through hole for blood to pass through.

Referring to Fig. 1, the blood filtering structure 1 of the present invention is disposed between the blood purification cartridge 10 of the conventional dialysis machine and the air control mechanism 11, wherein the blood filtering structure 1 is placed on a vibrator 20, so that The blood filtering structure produces a vibrating effect (as shown in Fig. 2), and mainly comprises a filter cartridge 12, an impact plate 13 disposed in the filter cartridge 12, and a plurality of filter plates 14, 15, 16; The filter cartridge 12 is a hollow cylinder having a drainage tube 17 connected to the blood vessel on the upper end side thereof, and an exhaust port 18 for exhausting the poison gas and a drainage space passing through the filter cartridge 12 at the upper end surface. 19; the impact plate 13 is disposed in the filter cartridge 2 corresponding to the drainage tube 17, and is provided with a zigzag 130 on the impact plate 13; the plate of the blood filter plate 14, 15, 16 is transparent The holes 140, 150, 160 are layered and fixed in the filter cartridge to form different levels of blood drainage space 19, and each blood drainage space 19 is further provided with a bacterial colony of different tissues, for example, the upper layer is slightly The dense tissue of the pile 151, while the second layer is the denser bristles 161, the bottom layer is the tightest tissue irregular bristles 170; and the filter cartridge 12 has the drainage space of the bacterial clusters 19 At the upper end, a drainage tube 192 is connected to the communication tube 191 for discharging the purified blood from the discharge port 193, and then flows to the blood purification cartridge 10 for a second filtration purification step (as shown in FIG. 3).

The blood filtration process (shown in Figures 3 and 4) is mainly caused by the patient's arm 2 leading out of the blood, and after being pressurized by the air control mechanism 11, the blood vessel 100 is introduced into the drainage tube 17 to filter the blood into the filter. The inside of the cylinder 2 (as shown in FIG. 4) directly hits the zigzag 130 of the impact plate 13, and cooperates with the vibration force generated by the vibration generator 20 to separate the bacteria and poison gas contained in the blood from the blood, and then passes through the blood filter plate 14 The through hole 140 enters the second layer of blood drainage space 19, wherein the separated poison gas is discharged from the exhaust port 18, and the separated blood and bacteria are further decomposed by the slightly dense tissue pile 151 to the pile 151 is used for a considerable amount of bacteria to be aggregated. After the amount of bacteria is reduced, it is then flowed out through the through hole 150 to the lower drainage space (as shown in Fig. 5), and then the second volume of the blood filter plate 16 is used to perform the second volume 161. Decomposes the blood, accumulates some of the bacteria, and finally passes from the through hole 160 to the bottom layer to the most dense irregular cluster. 170 is finally decomposed (as shown in Fig. 6), and the amount of blood to be purified reaches the upper end, and then flows from the communication tube 191 to the drainage tube 192, and then exits through the discharge port 193 to the blood purification tube 0 for the second passage. The blood purification step is performed after the blood is purified, and then the anticoagulant is injected and drained to the patient's arm 2 via the blood vessel 100 (as shown in Fig. 7).
