The discharge that drainage tube body be will not influence to hydrops in patient body is set.
Further, the scraping article is made of rubber material.
By using above-mentioned technical proposal, scraping article made of rubber had both had certain elasticity, it may have certain hardness,
The cleaning of realization that can be relatively good to conduction hole, while the rotation of screw rod will not be influenced.
Further, the screw rod is socketed with handle far from patient thoracic cavity one end outside.
By using above-mentioned technical proposal, handle can be convenient medical staff and rotate to screw rod, improve convenience.
In conclusion the utility model has the following beneficial effects:
1, by the way that the screwed pipe coaxial with drainage tube body, the screw rod being threadedly coupled with screwed pipe is arranged and is connected to spiral shell
Scraping article on bar can play the effect for striking off tamper in conduction hole；
2, by setting hollow structure for screw rod and scraping article, cleaning while cleaning in thoracic cavity can be played
The effect of tamper in conduction hole.
