Abstract
The utility model discloses an atrium-ventricle drainage tube, which comprises a tube body and flexible shaping wires. The tube body consists of a front section hose and a rear section hose. The harness of the front section hose is smaller than the hardness of the rear section hose. The end part of the front section hose is a closed structure. A plurality of drainage side holes are evenly arranged on the walls of the front section hose and the rear section hose. The atrium-ventricle drainage tube has the advantages that damages are not caused to a heart when the drainage tube is used, the tube body can be prevented from being blocked to the utmost extent, the synchronous drainage of an atrium and a ventricle is realized during an off-pump heart surgery and the drainage tube is more convenient to use.
Description
Technical field
This utility model relates to a kind of medical catheter, relates in particular to a kind of atrium-ventricle drainage tube.
Background technology
Carrying out cardiac operation, especially in the heart beating operation process, the doctor can use drainage tube that liquid in left atrium and the left ventricle or gas are carried out drain usually, guarantees that the art open country is clear.The employed drainage tube of doctor mostly is the soft body of front opening greatly at present, the opening of drainage tube is fitted because of negative pressure and ventricle wall easily in the use, cause damage to heart, the opening of drainage tube also sucks the left ventricle chordae tendineae easily when drain, cause damage and drainage tube to stop up, what hinder one's work normally carries out.Such drainage tube all will cooperate the drain core in use simultaneously, drain core commonly used is mostly made by the moulding silk of flexibility, utilize the auxiliary drainage tube of drain core to insert during use, then the drain core is extracted out to carry out drain, but because the front end of drainage tube commonly used is opening, this makes the drain core protrude from drainage tube during insertion easily, causes heart and injury simultaneously.
The utility model content
The purpose of this utility model just is to provide a kind of atrium-ventricle drainage tube, can effectively solve the problem that existing drainage tube easily stopped up and damaged easily heart.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of atrium-ventricle drainage tube, comprise body and flexible moulding silk, described body is made up of leading portion flexible pipe and back segment flexible pipe, the hardness of described leading portion flexible pipe is less than the hardness of back segment flexible pipe, and the end of leading portion flexible pipe is an enclosed construction, all has some drain side openings on the tube wall of leading portion flexible pipe and back segment flexible pipe.
Further, the aperture of drain side opening becomes big gradually from the leading portion flexible pipe to the back segment flexible pipe; Make drainage effect better.
Further, tube wall also is provided with the scale layer along the body length direction; Make things convenient for the doctor to grasp the length that body inserts atrium or ventricle.
Further, the moulding silk of described flexibility is arranged in the tube wall of body for several and along the length direction of body, and runs through leading portion flexible pipe and back segment flexible pipe.
Further, the moulding silk of described flexibility is one and is positioned at body inside, and is complementary with body.
Compared with prior art, advantage of the present utility model is: the end of leading portion flexible pipe is set to enclosed construction, in use can not fit with ventricle wall, can effectively avoid damaging heart, safer, offer the drain side opening at tube wall, can avoid body to be plugged to greatest extent, the drain same period of atrium and ventricle is used convenient when realizing the heart beating operation.
Description of drawings
Fig. 1 is the structural representation of this use new embodiment 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1: referring to Fig. 1, this utility model comprises body and flexible moulding silk, described body is made up of leading portion flexible pipe 1 and back segment flexible pipe 2, the hardness of described leading portion flexible pipe 1 is less than the hardness of back segment flexible pipe 2, safer in the process of inserting, can not cause damage to heart, wherein, the length of leading portion flexible pipe 1 is 1cm, the length of back segment flexible pipe 2 is 13cm, and the end of leading portion flexible pipe 1 is an enclosed construction, in use can not fit with ventricle wall, the end of back segment flexible pipe 2 is a joint, on the tube wall of leading portion flexible pipe 1 and back segment flexible pipe 2, all have some drain side openings 3, and it is big that the aperture of drain side opening 3 becomes gradually from leading portion flexible pipe 1 to back segment flexible pipe 2, can avoid body to be plugged to greatest extent, make drainage effect better, tube wall also is provided with the scale layer along the body length direction, the initiating terminal of this scale layer is positioned at the blind end of the leading portion flexible pipe 1 of body, make things convenient for the doctor to grasp the length that body inserts atrium or ventricle, the moulding silk of described flexibility is arranged in the tube wall of body for several and along the length direction of body, and run through leading portion flexible pipe 1 and back segment flexible pipe 2, flexible moulding silk is set in the tube wall, can not re-use the drain core like this, further improve safety and use convenient.
