Description
Technical Field
The application relates to a medical instrument, in particular to a retractable internal fixation drainage catheter device.
Background
The drainage tube is a medical appliance for clinical surgery drainage, which guides pus, blood and liquid accumulated in human tissues or body cavities to the outside of the body, prevents postoperative infection and promotes wound healing. A drainage tube passing through a chest wall or an abdominal wall, which is easily pulled and accidentally comes off due to inconvenient fixation; in addition, the current drainage tube is a single opening and is easily blocked.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present application aims to provide a retractable internal fixation drainage catheter device, which is not easy to be released from the body; the present application is also directed to a retractable internal fixation drainage catheter device whose opening is not easily blocked.
The application discloses but fixed drainage catheter device in retractable, it includes: the drainage tube comprises a drainage tube body, a balloon, an elastic fixing tube and a fixing sleeve;
the balloon is formed into a hollow structure by elastic materials and is fixed at the first end of the drainage tube body; forming a plurality of side holes along the periphery of the balloon, and forming a top hole at the first end of the balloon; the saccule is communicated with the drainage tube body through the side hole and the top hole of the saccule;
the elastic fixing tube is made of hard elastic material, and the cross section of the elastic fixing tube is of a C-shaped structure; the elastic fixing tube is sleeved on the drainage tube body;
the fixing sleeve is formed into a cylinder shape and can be sleeved on the drainage tube body in a sliding way; the retainer sleeve is adapted to fit over the second end of the flexible retainer tube to maintain its compressed shape when the flexible retainer tube is compressed and becomes smaller in diameter.
Preferably, the second end of the balloon forms a guide ramp to facilitate its reception in the resilient mounting tube.
According to the retractable internally-fixed drainage catheter device, the balloon with the larger diameter is formed at the first end of the drainage catheter body, so that the drainage catheter can be effectively prevented from being accidentally pulled out; the balloon can be contained in the elastic fixing tube when needed, so that the balloon can be conveniently inserted into or withdrawn from the hole of the chest wall or the abdominal wall.

Detailed Description
A retractable internally fixed drainage catheter device of the present application will be described in detail with reference to the accompanying drawings.
The application discloses but fixed drainage catheter device in retractable, it includes: a drainage tube body 2, a balloon 4, an elastic fixing tube 3 and a fixing sleeve 1;
the balloon 4 is formed into a hollow structure by an elastic material (such as medical silicon rubber) and is fixed at the first end of the drainage tube body 2; forming a plurality of side holes 5 along the periphery of the balloon 4, and forming a top hole 6 at a first end of the balloon 4; the saccule 4 is communicated with the drainage tube body through a side hole 5 and a top hole 6 of the saccule for drainage; the porous structure of the side holes 5 and the top holes 6 does not influence the drainage of other holes of the drainage tube even if one hole is blocked.
The elastic fixing tube 3 is made of hard elastic material (medical metal or hard plastic), the cross section of the elastic fixing tube is of a C-shaped structure, and as shown in fig. 3, two ends of the elastic fixing tube are staggered so as to be conveniently changed into a round tube with a smaller diameter when compressed. The elastic fixing tube 3 is sleeved on the drainage tube body 2.
The fixing sleeve 1 is formed into a cylinder shape and can be sleeved on the drainage tube body 2 in a sliding way; the fixing sleeve 1 is used to be fitted over the second end of the elastic fixing tube 3 to maintain its compressed shape when the elastic fixing tube 3 is compressed to be reduced in diameter.
The second end of the balloon 4 forms a guide ramp to facilitate its reception in the resilient fixation tube 3.
Before the drainage tube body is arranged, the saccule is arranged in the compressed elastic fixing tube, as shown in figure 5, and the second end of the compressed elastic fixing tube is sleeved by the fixing sleeve at the moment so as to keep the compressed shape; after being compressed, the two staggered ends of the elastic fixing tube are overlapped, one is positioned at the inner side, and the other is positioned at the outer side, so that the elastic fixing tube becomes a tube with smaller diameter and is suitable for being inserted into a hole on the chest wall or the abdominal wall; then, the fixing sleeve is taken down, and the elastic fixing tube is released, so that the saccule contained in the elastic fixing tube can be easily pushed out; at the moment, if the elastic fixing tube can be directly pulled out from the hole, the elastic fixing tube is directly pulled out, and if the elastic fixing tube is not easy to directly pull out, the elastic fixing tube is compressed again and sleeved by a fixing sleeve and then pulled out.
The process of taking out the drainage tube body is opposite to the process of putting in the drainage tube body; as shown in fig. 6, the elastic fixing tube is first compressed and inserted into the hole of the chest or abdominal wall 7, then the fixing sheath is removed to open the elastic fixing tube, the balloon is withdrawn into the elastic fixing tube, then the elastic fixing tube is compressed again and fixed by the fixing sheath, and finally the elastic fixing tube and the balloon are withdrawn together.
Claims (2)
