Abstract

The invention relates to a vena cava drainage tube with two blocking cuffs. A conical cuff is arranged at each of the top and middle part of a drainage tube body; a pipe joint is arranged at the other end of the drainage tube body; the tip ends of the two conical cuffs are opposite to each other; the two conical cuffs are respectively connected with an upper vena cava cuff liquid filling joint and a lower vena cava cuff liquid filling joint; a telescopic tube is arranged on a tube body of the drainage tube between the two conical cuffs; a supporting telescopic cuff is arranged in the telescopic tube and is connected with a supporting telescopic cuff liquid filling joint; and an upper vena cava inlet and a lower vena cava inlet are formed in positions, facing to the drainage tube body, at the tip ends of the two conical cuffs. According to the vena cava drainage tube with the two blocking cuffs, by the use of the dual protection design that the two cuffs are cooperated with the supporting telescopic cuff to block a blood vessel, bundling up in a narrow chest is not needed; and the blood vessel can be blocked by filling of normal saline, and no risk is caused to operation. Furthermore, the stress area of the two conical cuffs is large, and the blocking effect is good; and the blood vessel wall is not liable to break, so that the operation risk is reduced, and the vena cava drainage tube is safe to use.

Description

The double caval vein drainage tube blocking cuff of band
Technical field
The present invention relates to a kind of caval vein drainage tube, the specifically a kind of caval vein drainage tube of band double blocking-up cuff, Belong to technical field of medical instruments.
Background technology
With the extensive development of cardiac minimally-invasive surgery, the foundation how more simplifying extracorporeal circulation reduces having around heart Wound operation is more and more important；With the progress of heart technology, heart second operation ratio also more and more higher, and separate serious adhesion Superior and inferior vena cava considerably increase wound surface, the possibility damaged beyond increasing bleeding and heart.Conventional extracorporeal circulation is set up to be needed To put pipe respectively in superior and inferior vena cava respectively, dissociate around superior and inferior vena cava gap cuff, dividing when needing to block Do not block.Take up room big, operation is wasted time and energy, especially little in Cardiac operation with mini-trauma working place, and during Heart reoperation Surrounding adhesion effectively causes and separates difficulty.It is thus desirable to designing a kind of caval vein drainage tube, thus when extracorporeal circulation is set up in simplification Separate the process blocking superior and inferior vena cava, the adhesion around superior and inferior vena cava simultaneously does not affect the foundation of extracorporeal circulation.
Content of the invention
The technical problem to be solved is, proposes a kind of double caval vein drainage tubes blocking cuffs of band, by Double blocking-up blocking cuff, realizing to superior and inferior vena cava are arranged on drainage tube, reduces the risk of bleeding and accidental injury.
The present invention solve above technical problem technical scheme be：There is provided a kind of band double caval vein drain blocking cuff Pipe, including drain tube body, the top of described drain tube body and middle part are respectively provided with a taper cuff, and described drainage tube is originally The body other end is provided with pipe joint, and described pipe joint includes superior vena cava catheter adapter, postcava catheter adapter, superior vena cava set Capsule topping up joint, postcava cuff topping up joint and support telescopic cuff topping up joint, the point of two described taper cuffs End is oppositely arranged, and two taper cuffs are connected with superior vena cava cuff topping up joint and postcava cuff topping up joint respectively； Drainage tube body between two taper cuffs is provided with telescoping tube, in described telescoping tube, is provided with support telescopic cuff, described Support telescopic cuff is connected with described support telescopic cuff topping up joint；With the drawing of the tip direction of two described taper cuffs Flow tube body is provided with superior vena cava import and postcava import, described superior vena cava import and postcava import with described Superior vena cava catheter adapter is connected with postcava catheter adapter.
The restriction technical scheme further of the present invention, the double caval vein drainage tube blocking cuff of aforesaid band, described epicoele Vein import and postcava entrance are equipped with pressure tap, described pressure tap be arranged on the pressure measuring tie-in phase that pipe joint goes out Even, by the pressure tap of both sides, barrier effect being judged, thus realizing the real-time monitoring to operation process, providing to doctor Accurately judge.
The caval vein drainage tube of aforesaid band double blocking-up cuff, two described taper cuffs are equipped with development index strip, Physical location residing for taper cuff is monitored by external equipment, is easy to patient and accurately implements to perform the operation.
The caval vein drainage tube of aforesaid band double blocking-up cuff, it is straight that described flexible pipe diameter is less than described drain tube body Footpath, convenient operation, it is to avoid flexible pipe diameter is excessive, make flexible pipe outer wall and vein inwall produce friction, affect operation process and put Pipe.
The caval vein drainage tube of aforesaid band double blocking-up cuff, a diameter of epicoele at described taper cuff maximum gauge is quiet Arteries and veins or 1.5-3 times of postcava diameter, by the major diameter of taper be in vein intracavity carry out spacing it is ensured that caval vein Drainage tube working stability.
Further, the caval vein drainage tube of aforesaid band double blocking-up cuff, the top of described drain tube body is in circular arc Shape, is easy to puncture the guiding operation leading core, that reduces drainage tube puts pipe resistance.
The invention has the beneficial effects as follows：
The present invention, when carrying out operation on heart, needs the position of drain by puncturing to lead core and be inserted into heart along femoral vein, by drain Tube body is inserted in puncture leads core, under puncturing the guiding leading core, according to the development index strip instruction in two cuffs on drainage tube It is inserted to the position needing drain, extract puncture out and lead core, being slowly filled with normal saline by cuff tube for transfusion makes two taper cuffs Expand and block blood vessel, more intracapsular to the support telescopic set at the middle part of drainage tube pour normal saline, and then the taper sheath to two ends The outside jack-up of capsule is realized supporting positioning, thus ensureing the safety and stability of the drain in operation on heart.Operation on heart passes through after terminating Tube for transfusion releases normal saline, and cuff is shunk and can be extracted drain tube body out.As can be seen here due to employing two cuffs and joining The combination closing support telescopic cuff blocks blood vessel, and duplicate protection design is tied up so that noting be used in narrow and small thoracic cavity, is filled with Normal saline both can block blood vessel, and also operation will not be caused with risk, operation very simple, efficient and convenient.And two tapers The lifting surface area of cuff is big, and barrier effect is good, and does not allow fragile blood vessel wall, reduces operation risk, using safety.
