Self-control pulse irrigating tube

Abstract

The invention relates to a medical irrigating tube, in particular to a self-control pulse irrigating tube, which comprises a drainage tube. A filling-end pluggable joint and a drainage-end pluggable joint are respectively mounted at two ends of the drainage tube through adjustable valves, side through holes spirally arranged on the wall of the drainage tube, an elastic balloon is connected to thefilling-end pluggable joint in series, and the diameters of the side through holes are reduced sequentially from the filling-end pluggable joint to the drainage-end pluggable joint. Compared with theprior art, the self-control pulse irrigating tube has the advantages that high negative pressure is formed in the irrigating tube by the elastic balloon within a short time and irrigates blood clots or fall-off tissues which are attached to block the side through holes of the drainage tube under the negative pressure action; since the diameters of the side through holes are reduced sequentially from the filling-end pluggable joint to the drainage-end pluggable joint, irrigation solution is easy to flow to a focus region due to the fact that the side through holes close to the filling end are larger, and larger blood clots and necrotic fall-off tissue are not easy to be sucked to cause blockage due to the fact that the side through holes close to the drainage end are smaller when the irrigating tube is used for irrigating under normal pressure.

Description

[0001] Technical field: [0002] The invention relates to a medical lavage tube, in particular to an automatic control pulse type lavage tube. Background technique: [0003] Deep tissue infection has always been a difficult point in surgical treatment. Because the deep soft tissue is rich and multi-layered, it is difficult to achieve complete debridement and drainage. Therefore, debridement and lavage treatment are usually performed on the basis of anti-infective drug treatment. At present, the commonly used lavage can be divided into two categories: the double-tube type and the single-tube through-type type in which the perfusion tube and the drainage tube are separated. There are certain deficiencies: [0004] Advantages and disadvantages of the double-tube type: the double-tube type means that the perfusion tube and the drainage tube are two tubes with open ends or side holes. One tube injects lavage fluid into the lesion, and the other tube drains it. If the perfusion...

[0004] Advantages and disadvantages of the double-tube type: the double-tube type means that the perfusion tube and the drainage tube are two tubes with open ends or side holes. One tube injects lavage fluid into the lesion, and the other tube drains it out.

However, due to tissue swelling or adhesion, a gap is formed between the two tubes, which are closed into two cavities that are not connected to each other and cause blockage; or because the opening of the end of the drainage tube is as large as the diameter, it is easy to inhale thrombus or elongated exfoliated tissue , forming a thromboembolic blockage

Moreover, the double-pipe pipeline cannot slide, and it is difficult to solve the blocking problem

If the irrigation tube and the drainage tube are close to each other (for example, socketed or placed in parallel), similar to the single through tube, the lavage fluid will easily flow out of the drainage tube without passing through the lesion area, forming a "short circuit" between the irrigation tube and the drainage tube. ", the lavage efficiency is low, although it can reduce the chance of blocking, it also lacks an effective way to unblock

[0005] Advantages and disadvantages of the single-tube type: the single-tube type means that the perfusion tube and the drainage tube are a single tube that runs through one body, and a side hole is made in the part passing through the lesion area

However, because the pipeline is integrated, the lavage fluid sometimes directly enters the drainage part without passing through the side hole, causing a "short circuit" and low lavage efficiency.

[0006] Common defects of the existing two types of lavage tubes: no valve and interface design, difficult to control the lavage speed and method, and replacement of damaged infusion sets and negative pressure drainage devices caused by repeated use, which is not convenient for filling drugs and taking drainage fluid For testing; the pressure of the perfusion part is small and cannot be adjusted

[0007] The Patent Office of the State Intellectual Property Office has announced the patent: CN201631763U, which can only control the lavage speed; for large or complex structures (such as intra-articular infection), it is difficult to achieve sufficient perfusion effect; it cannot achieve large flow lavage
