Embodiment 1

[0025] a connecting pipe, such as figure 1 , figure 2 with Figure 4 As shown, it includes a hollow cylindrical syringe connection tube 1, the liquid outlet 1a of the syringe connection tube 1 is connected with a connection block 2, and a through hole for the syringe connection tube 1 to pass through is opened in the connection block 2, and the syringe connection tube 1 and the hole wall of the through hole in the connecting block 2 are closely bonded, the inside of the connecting block 2 is provided with a cavity 21, and the syringe connecting tube 1 communicates with the cavity 21, and the bottom surface of the syringe connecting tube 1 is also installed with The dialysis circulation pipe 3 and the dialyzer threaded pipe 4, and the dialysis circulation pipe 3 and the dialyzer threaded pipe 4 are all communicated with the cavity 21, and there is also a dialysis circulation pipe 3 and the dialyzer threaded pipe 4 in the connecting block 2. and the dialysis circulation pipe ...

Embodiment 2

[0031] In the specific operation, when the injection pressure of the syringe is injected into the dialyzer or the dialysis circuit, the tiny blood clots cannot be filtered out, and the blood mixed with small blood clots is very easy to be reinfused back to the patient during the emergency operation, which brings great harm to the patient. The problem of the unsafe hidden danger of thrombus, therefore, on the basis of embodiment 1, valve 31 is improved, as a kind of preferred embodiment, as image 3 As shown, a blood clot filter 32 is installed on the upper surface of each valve 31 .

[0032] In this embodiment, the blood clot filter 32 is tightly adhered to the valve 31 to ensure the firmness of its structure and prevent it from falling off.

[0033] In this embodiment, through the blood clot filter 32 provided, it is convenient to filter the small blood clots, avoiding the blood clots from being reinfused into the patient, and solving the problem of emergency operation when t...

Embodiment 3

[0035] In the specific operation, because the drawn blood contains blood clots, and larger blood clots in the pipeline are likely to cause pipeline blockage, resulting in the failure of the external circulation pipeline or dialyzer to continue to be used, they can only be replaced, which is to a certain extent It wastes time and increases the economic burden of the patient. Therefore, on the basis of Embodiment 1, improvements are made to the dialysis circulation tube 3 and the dialyzer threaded tube 4. As a preferred embodiment, such as Figure 5 with Image 6 As shown, a fixed ring 33 is installed on the pipe wall of the dialysis circulation pipe 3 and the dialyzer threaded pipe 4, and an annular groove 331 is provided inside each fixed ring 33, and a fixed ring 33 is installed on the groove wall of each annular groove 331. Blocks 332, the bottom surface of each fixed block 332 is equipped with a blood clot dividing plate 3321.

[0036]In this embodiment, the section of the...

Abstract

The invention relates to the technical field of connecting pipes, in particular to a connecting pipe. The connecting pipe comprises a hollow cylindrical syringe connecting pipe, a liquid outlet end ofthe syringe connecting pipe is connected with a connecting block, the interior of the connecting block is provided with a hollow cavity, the syringe connecting pipe is communicated with the cavity, the bottom face of the syringe connecting pipe is provided with a dialysis circulation pipe and a dialysis device threaded pipe, and valves are installed on the dialysis circulation pipe and the pipe wall of the dialysis device threaded pipe. By the arrangement of the valves and a blood clot filer net, the blood clot filter net can block blood clots of any size to prevent the blood clots from entering the dialysis device or a pipeline, when pressure is internally pumped to the syringe by the dialysis circulation pipe and the dialysis threaded pump, the valves are expanded to make it convenientfor the blood clots in the dialysis device or the pipeline to be rapidly pumped out, and the problem of the potential safety hazard that blood mixed with the blood clots is easily delivered back to apatient once blood clotting takes place in in-vitro circulation bringing thrombus to the patient is solved.

Description

technical field [0001] The invention relates to the technical field of connecting pipes, in particular to a connecting pipe. Background technique [0002] During the blood purification treatment, the blood pump stops due to various reasons, and the blood pump stops frequently for many times or for a long time. The dialyzer and or the dialysis circuit will have grade II~III blood coagulation, and eventually the blood will not return to the machine. The common treatment for this phenomenon is to either discard the extracorporeal circulation circuit and (or) dialyzer directly, interrupt the treatment, and waste the blood in the whole set of dialysis circuit and (or) dialyzer; After the dialyzer and / or dialysis tubing are discarded, replace with a new set of dialysis tubing and / or dialyzer and pre-flush the machine for treatment. The above treatment will lead to blood loss of the patient, aggravation of anemia, affect the treatment effect of the patient, and also increase the t...
