Description
Technical field
This utility model relates to armarium, particularly a kind of blood perfusion device Special connecting device.
Background technology
Blood purification treatment comprises hemodialysis, hemofiltration, during high flux hemodialysis, CRRT and hemoperfusion etc., the perfusion device of connecting on the mode bases such as filter such as dialyser, can well remove the interior heterotoxin in patient body, accept extensively for clinical, but before using, perfusion device and other filters need independent a large amount of liquid that rushes in advance that rush in advance and use, the plug of interface is exposed in air interface and socket, there is the risk of bacterial infection, convert frequently in addition interface, strengthened medical personnel's workload.At present existing complete circulation line gets up perfusion device and dialyzers in series, treats 2 hours, without dismounting, has still fixed the front and back position of filter and perfusion device, cannot exchange freely the front and back position of filter and perfusion device, affects therapeutic effect.Blood coagulation is also the Risks in blood purification treatment, once generation blood coagulation should be carried out immediately heparin saline and rush in advance, existing pipeline infusion pipeline is long in the arterial end time, and that blood coagulation generally comes is fast, so should carry out heparin saline flushing to perfusion device within the short to the greatest extent time.
There is following defect in existing blood perfusion device:
1. when hemodialysis starts to rush in advance, because need to using a large amount of heparin, rushes in advance perfusion device, so perfusion device need to separate pre-punching separately with dialyser, after pre-punching finishes, again both are linked together with connection tube, during pre-punching, the exposure of perfusion device and dialyser interface makes perfusion device and the easy microbiological contamination of dialyser, increases Operative risk; If by dialyser and perfusion device pre-punching simultaneously, a large amount of heparin pour dialyser, the excessive patient of heparin has hemorrhage risk;
2. hemodialysis 2 hours, because perfusion device needs dismounting, perfusion device needs to take pipeline apart after blood back to be proceeded, and tremulous pulse interface and dialyser arterial end are exposed in air, and the one, easy microbiological contamination two is that blood ingress of air easily causes blood coagulation impact to treat;
3. the pipe-line system of the pre-punching of existing a whole set of band, can only carry out the preposition connection of blood perfusion device, cannot adjust flexibly perfusion device position.
Utility model content
The purpose of this utility model is to provide a kind of blood perfusion device Special connecting device.
The purpose of this utility model is achieved through the following channels: a kind of blood perfusion device Special connecting device, filter connection tube one end connects female Luer, the other end connects a threeway, two other interface of a threeway connects respectively filter treatment tube and a blood perfusion device connection tube, the other end of filter treatment tube connects No. two threeways, two other interface of No. two threeways connects respectively vascular access connection tube and No. two blood perfusion device connection tubes, and the other end of vascular access connection tube connects arteriovenous pipeline interface; On a described blood perfusion device connection tube and No. two blood perfusion device connection tubes, be respectively equipped with ascending pipe and thief hatch.
As the further optimization of this programme, in a described blood perfusion device connection tube, No. two blood perfusion device connection tubes, vascular access connection tube, filter treatment tube, tubing clamp is installed.
This utility model blood perfusion device Special connecting device, compared with the prior art, tool has the following advantages:
1. can arbitrarily regulate the front and rear of perfusion device and filter, it is more convenient to use.
2. from pre-punching, treatment, machine, and even the situation such as blood coagulation, allergy that runs into is all without lower machine, can operate pipeline as required;
3. can carry out therapeutic alliance with multiple filter, treatment pattern chooses at random, and is not subject to the restriction of specific pipeline;
4. many machines will be applied own special blood purifying pipeline, and unrestricted for connection tube, this connection tube can not limit machine and pipeline brand, use standard interface to be all suitable for all machines and brand.
