Description

Multifunctional efficient sample remaining hydrops puncture device
Technical Field
The utility model relates to a hydrops puncture stays a kind technical field, specifically is a multi-functional high efficiency stays a kind hydrops piercing depth.
Background
The effusion is a pathological manifestation, namely a large amount of liquid appears in a place where a large amount of liquid should not appear in a human body, the liquid is pathological, and a small amount of liquid appears in the chest, the abdominal cavity, the uterus and the brain, which comprises effusion, effusion and other liquid, and the components are complex; the causes are also varied, such as infection, tumor, tuberculosis, heart failure and even immunological reactions, which can lead to the production of fluid accumulation.
The traditional apparatus for sucking in vivo liquid in hospital comprises a large-size medical injector, a rubber tube is connected between the injector and a needle head; when the effusion in the body of a patient is more and needs to be repeatedly pumped, the rubber tube needs to be closed by the hemostatic forceps when one syringe is full, and then the syringe is detached to discharge the effusion; then the injector is connected to the rubber tube again, the hemostatic forceps are opened, the steps are repeated, and the overall operation mode is complex.
In order to improve the above condition, a three-way pipe is arranged, a three-way valve is arranged on the three-way pipe, and the switching of the pipeline passages can be realized by rotating the three-way valve; one end of the three-way pipe is communicated with the injector, the other end is communicated with the indwelling bag, and the needle head is arranged at the other end. During suction, the needle head is placed at the effusion, the piston of the injector is pulled, and the effusion enters the injector; then the three-way valve is switched to communicate the syringe with the indwelling bag; pushing the piston of the syringe to inject the effusion into the indwelling bag; then switch the three-way valve again and make syringe and syringe needle intercommunication, repeat above-mentioned step and can realize the repeated suction operation of hydrops. By adopting the mode, particularly when the pleural and peritoneal effusion is extracted, the injector does not need to be repeatedly disassembled, the suction efficiency can be accelerated, and the pain of a patient is reduced; moreover, compare in the extraction in-process need with the syringe with the hydrops transfer to other containers in, the risk that the hydrops drips the polluted operational environment appears easily, the hydrops extraction of above-mentioned mode is in a more confined pipeline, more clean health.
However, the above technology still has the following technical problems:
1. detection of each aspect such as biochemical routine detection, microbial detection and tumor cell detection need generally be carried out to the hydrops extraction back, adopts above-mentioned structure to carry out the hydrops extraction, and postoperative medical personnel need separately keep somewhere the hydrops in the bag and leave the appearance, and then send into different detection departments with the sample, and the operation is still troublesome.
2. The difficult and complicated bacteria such as tubercle bacillus, Nocardia and the like, tumor cells and the like are small in the amount of accumulated liquid, and the problem of low detection rate is easy to exist during the inspection.
SUMMERY OF THE UTILITY MODEL
The utility model provides a multi-functional high efficiency stays a kind hydrops piercing depth can solve among the prior art hydrops extraction back, still need part the hydrops of keeping somewhere in the bag, the operation still more trouble problem.
The application provides the following technical scheme:
a multifunctional high-efficiency sample-remaining effusion puncture device comprises a puncture end, a suction part, a sample-remaining bag and a multi-way catheter, wherein the puncture end, the suction part and the sample-remaining bag are communicated through the multi-way catheter; the multi-way pipe is provided with a sampling end; and the multi-way conduit is provided with a switching piece for switching the passage; an anticoagulant adding part is arranged on the sample reserving bag.
Has the advantages that:
1. compared with the prior art, the method has the advantages that all the effusion is put into the retention bag, and after the suction is finished, the effusion in the retention bag needs to be separated and then sent to each detection position; according to the scheme, the sampling end and the sample reserving bag are arranged on the multi-way pipeline, the pipeline is switched through the switching piece, and the accumulated liquid can be respectively injected into the sampling end or the sample reserving bag as required in the process of sucking the accumulated liquid by the suction part; for example, when the switching piece switches the pipeline to communicate the suction part with the sampling end, medical staff can preferentially sample from the sampling end and then send the sample to a clinical laboratory to perform routine, biochemical, microbial and other detection; when the switching piece switches the pipeline to enable the suction part to be communicated with the sample reserving bag, the suction part can inject the taken accumulated liquid into the sample reserving bag to reserve a sample, and detection of falling cells and the like is facilitated; in conclusion, the technology realizes the functions of separately sampling and reserving samples in the process of extracting the effusion, and the operation of separating the effusion after the operation is not needed any more, so that the technology is more convenient.
2.
