Embodiment 1

[0029] refer to figure 1 , a sustainable perfusion drainage tube provided by Embodiment 1 of the present invention, comprising a tube body 10 and a rear intubation tube connected to the tube body 10 and located at the rear end of the tube body 10, the tube body 10 has mutually isolated drainage tubes along its length direction cavity 11 and perfusion cavity 12, the rear intubation tube includes a first branch tube 20 communicating with the drainage cavity 11 and a second branch tube 30 communicating with the perfusion cavity 12, and the front end of the tube body 10 is provided with a plurality of tubes communicating with the perfusion cavity 12. The liquid outlet 40 and the side wall of the tube body 10 are also provided with a drainage port 13 communicating with the drainage cavity 11 , and there is a distance between the drainage port 13 and the plurality of liquid outlets 40 .

[0030] In the embodiment of the present invention, compared with the single-tube multi-tube dra...

Embodiment 2

[0038] refer to figure 2 The difference between the sustainable perfusion and drainage tube provided in the embodiment of the present invention and the sustainable perfusion and drainage tube in Embodiment 1 is that a balloon cavity 14 is also provided in the tube body 10, and the balloon cavity 14 is connected with the drainage cavity 11, the perfusion cavity Cavities 12 are arranged in parallel, and the front end of tube body 10 is also provided with a positioning balloon 15 communicating with balloon cavity 14 for injecting liquid, and the rear intubation tube also includes a third branch tube 60 communicating with balloon cavity 14. A one-way valve 61 is provided on the branch pipe 60 .

[0039] The drainage tube will generally be left in place for 5-7 days according to the hematoma clearance. During the drainage process, it is particularly important to prevent the drainage tube from prolapse. In this embodiment, when the drainage tube is punctured in place, a proper amo...

Abstract

The invention relates to the technical field of medical instruments and provides a continuous perfusion drainage tube which comprises a tube body and a rear cannula, wherein the rear cannula communicates with the tube body and is positioned at the rear end of the tube body; a drainage cavity and a perfusion cavity which are isolated from each other are formed in the tube body along a length direction of the tube body; the rear cannula comprises a first branch tube communicating with the drainage cavity and a second branch tube communicating with the perfusion cavity; a plurality of liquid outlet communicating with the perfusion cavity is formed in the front end of the tube body; a drainage hole communicating with the drainage cavity is also formed in the side wall of the tube body; and thedrainage hole and the plurality of the liquid outlets are formed in distances. Compared with a drainage tube of a single tube with multiple branch tubes in the prior art, the continuous perfusion drainage tube is provided with the drainage cavity and the perfusion cavity which are isolated from each other in the tube body, so that drainage and perfusion can be separated, a larger drainage cavitycan be formed under a condition of an identical diameter, the drainage velocity can be increased, and the risk of tube blocking can be reduced; and as the drainage hole is formed in a certain distancefrom the liquid outlets, a medicine can be perfused continuously to react with hematomae sufficiently, and thus medicinal effects of the medicine can be taken into play sufficiently.

Description

technical field [0001] The invention relates to the technical field of medical devices, and in particular provides a sustainable perfusion and drainage tube. Background technique [0002] In today's society, people's unhealthy lifestyle, increased life pressure, lack of exercise and other reasons lead to hypertensive cerebral hemorrhage has become a common and frequently-occurring disease. The disease has three high characteristics of high morbidity, high mortality and high disability. Moreover, in hypertensive cerebral hemorrhage, about 80% of the intracranial hemorrhage occurs in the basal ganglia, and the basal ganglia is the area where important nerve center conduction fibers pass. Therefore, hypertensive cerebral hemorrhage often causes patients to die or become disabled. Therefore, it is of great significance to use reasonable medical equipment for effective treatment of hypertensive cerebral hemorrhage. [0003] In the past, craniotomy was often used for clinical tr...
