技术领域 technical field
本发明属于医用手术器械领域，具体涉及一种用于心脏外科手术中的医用左心引流管。The invention belongs to the field of medical surgical instruments, in particular to a medical left heart drainage tube used in heart surgery.
背景技术Background technique
目前，在心脏外科手术中应用最广泛的左心引流管在进行左心负压吸引时，由于位置等原因易造成引流管吸附左心房（室）壁而导致引流不畅，从而使手术视野不清晰及反复调整引流管，造成手术时间相对延长，增加了潜在的手术风险。At present, the left heart drainage tube, which is most widely used in cardiac surgery, is likely to cause the drainage tube to absorb the wall of the left atrium (ventricular) due to the position and other reasons when performing left heart negative pressure suction, resulting in poor drainage and poor surgical field of vision. Clear and repeated adjustment of the drainage tube will prolong the operation time and increase the potential operation risk.
发明内容Contents of the invention
为了解决现有左心引流管存在的问题，本发明的目的是提出一种医用左心引流管，通过在引流管的端部设置球囊，利用球囊的支撑作用使引流管与左心房（室）壁分离，在进行左心负压吸引时不会吸附左心房（室）壁，从而达到较好的引流效果。In order to solve the problems existing in the existing left heart drainage tube, the object of the present invention is to propose a medical left heart drainage tube, by setting a balloon at the end of the drainage tube, and using the support function of the balloon to make the drainage tube and the left atrium ( Ventricle) wall separation, it will not adsorb the left atrium (ventricular) wall during left heart negative pressure suction, so as to achieve better drainage effect.
为了实现上述发明目的，本发明采用如下所述的技术方案：In order to realize the above-mentioned purpose of the invention, the present invention adopts the technical scheme as follows:
一种医用左心引流管，包括引流管体，引流管体的一端部设有主引流孔，在引流管体一端的侧壁上开设有侧引流孔，在侧引流孔两侧的引流管体侧壁上分别设置有一球囊，两个球囊通过灌注管连接有灌注接头，所述灌注管嵌设在引流管体侧壁内，灌注管的一端与两个球囊相连通，另一端伸出引流管体的侧壁连接有灌注接头，灌注接头上还配设有锥形密封塞。A medical left heart drainage tube, comprising a drainage tube body, one end of the drainage tube body is provided with a main drainage hole, a side drainage hole is opened on the side wall of one end of the drainage tube body, and the drainage tube body on both sides of the side drainage hole A balloon is respectively arranged on the side wall, and the two balloons are connected with a perfusion joint through a perfusion tube. The perfusion tube is embedded in the side wall of the drainage tube body. The side wall of the outlet and drainage tube body is connected with an infusion joint, and the infusion joint is also equipped with a tapered sealing plug.
进一步地，所述的侧引流孔在引流管体的侧壁上沿圆周方向均布设有若干圈。Further, the side drainage holes are evenly arranged in several circles along the circumferential direction on the side wall of the drainage tube body.
进一步地，所述引流管体采用硅胶制作。Further, the drainage tube body is made of silica gel.
由于采用上述技术方案，本发明具有以下优越性：Owing to adopting above-mentioned technical scheme, the present invention has the following advantages:
本发明在使用时，通过灌注接头向灌注管内注入生理盐水，并用锥形密封塞密封灌注接头，生理盐水沿灌注管分别进入两个球囊内使得球囊膨胀，使得引流管体与左心房（室）壁分离而不易贴壁，并且避免了因密度的差异使引流管漂浮于血液之上，使得引流效果较好，使手术易于进行，并且易于操作。When the present invention is in use, physiological saline is injected into the perfusion tube through the perfusion joint, and the perfusion joint is sealed with a tapered sealing plug. The normal saline enters the two balloons along the perfusion tube to expand the balloons, so that the drainage tube body is in contact with the left atrium ( Chamber) wall is separated and not easy to adhere to the wall, and avoids the drainage tube floating above the blood due to the difference in density, so that the drainage effect is better, and the operation is easy to perform and easy to operate.

下面结合附图及实施例对本发明作进一步详细的说明。The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
如图1所示，一种医用左心引流管，包括引流管体7，引流管体7的一端部设有主引流孔1，在引流管体7一端的侧壁上开设有侧引流孔3，在侧引流孔3两侧的引流管体侧壁上分别设置有一球囊2，两个球囊2通过灌注管4连接有灌注接头5，所述灌注管4嵌设在引流管体1侧壁内，灌注管4的一端与两个球囊2相连通，另一端伸出引流管体的侧壁连接有灌注接头5，灌注接头5上还配设有锥形密封塞6。As shown in Figure 1, a medical left heart drainage tube includes a drainage tube body 7, one end of the drainage tube body 7 is provided with a main drainage hole 1, and a side drainage hole 3 is provided on the side wall of one end of the drainage tube body 7 A balloon 2 is respectively arranged on the side wall of the drainage tube body on both sides of the side drainage hole 3, and the two balloons 2 are connected with a perfusion joint 5 through the perfusion tube 4, and the perfusion tube 4 is embedded on the side of the drainage tube body 1 Inside the wall, one end of the perfusion tube 4 communicates with the two balloons 2 , and the other end protrudes from the side wall of the drainage tube to connect the perfusion joint 5 , and the perfusion joint 5 is also provided with a tapered sealing plug 6 .
所述的侧引流孔3在引流管体的侧壁上沿圆周方向均布设有若干圈，便于提高引流效果。The side drainage holes 3 are evenly arranged in several circles along the circumferential direction on the side wall of the drainage tube body, so as to improve the drainage effect.
所述的引流管体1可以采用硅胶制作，防止在使用过程中对人体组织产生的碰伤、刮伤等。The drainage tube body 1 can be made of silica gel to prevent bumps and scratches on human tissues during use.
本发明在具体应用时，该左心引流管内插设有内芯，将本发明的引流管带内芯插入患者体内后，抽出内芯，通过灌注接头向灌注管内注入生理盐水，并用锥形密封塞密封灌注接头，生理盐水沿灌注管分别进入两个球囊内使得球囊膨胀，使得引流管体与左心房（室）壁分离而不易贴壁，也使得侧引流孔不会贴壁，并且避免了因密度的差异使引流管漂浮于血液之上；需要撤去引流管时，用注射器通过灌注接头抽出球囊内部的生理盐水即可；相比于传统的左心引流管，大大提高了引流效果，且使手术易于进行和操作，同时，也增强了手术过程的安全性。In the specific application of the present invention, the left heart drainage tube is inserted with an inner core. After the drainage tube with the inner core of the present invention is inserted into the patient's body, the inner core is drawn out, and physiological saline is injected into the perfusion tube through the perfusion joint, and sealed with a cone. The plug seals the perfusion joint, and physiological saline enters the two balloons along the perfusion tube to inflate the balloons, so that the drainage tube body is separated from the wall of the left atrium (chamber) and is not easy to adhere to the wall, and the side drainage hole will not adhere to the wall, and It avoids the drainage tube floating above the blood due to the difference in density; when the drainage tube needs to be removed, use a syringe to draw out the saline inside the balloon through the perfusion joint; compared with the traditional left heart drainage tube, the drainage is greatly improved Effect, and make the operation easy to carry out and operate, and at the same time, also enhance the safety of the operation process.
