Description
The technical field is as follows:
the utility model relates to the technical field of medical equipment, concretely relates to novel atrium attracts pipeline.
Background art:
in the external circulation surgery of great cardiac vascular surgery, a left atrial cannula is often used to drain the blood from the left heart. It mainly has the following functions: first, the left heart is decompressed. At the initial stage of extracorporeal circulation establishment, the heart beats, and effective left ventricular drainage can reduce the pressure in the left heart and avoid the damage caused by left ventricular expansion. Second, a clear surgical field is maintained. During the open-heart surgery, blood always flows back to the left atrium through the pulmonary veins, and if the blood is not properly and continuously sucked, the surgical field is full of blood, which affects the surgical operation. Left heart drainage allows the surgeon to perform the procedure unhindered in a relatively clear surgical field of view. And thirdly, lung protection. If the blood returned from the left heart is not properly sucked, the pressure in the left heart increases, which increases the pressure of the blood vessels in the lung, and over time, edema of the lung tissue may occur, causing complications, such as lung perfusion. The specific operation is that the end with the drainage hole on the left atrium drainage tube is inserted into the atrium, and the blood in the atrium enters the drainage tube from the drainage hole under the action of negative pressure suction and then flows into a blood storage tank of an extracorporeal circulation system through the drainage tube. However, due to the particularity of the heart structure and the soft tissue structure of the atrial wall, after the drainage tube is inserted into the atrium, the nearby atrial wall is easily adsorbed to the periphery of the orifice under the action of local negative pressure to block the drainage hole, so that the drainage efficiency is influenced. When all drainage holes are completely wrapped by the left atrial wall, the drainage function of the left atrium is completely lost, adverse consequences such as cardiac dilatation, unclear surgical visual field, pulmonary edema and the like can be caused finally, the drainage tube is repeatedly adjusted, the relative prolongation of the surgical time and the mechanical damage to the heart are caused, and the potential surgical risk is increased. Patent No. ZL 201820638588.7's patent sets up left bearing structure and right bearing structure respectively through controlling the side on the body of drainage tube, and left bearing structure includes plate, sliding sleeve and gasbag, and the plate sets firmly in the body outside, and sliding sleeve slidable mounting will extrude the gasbag and make the gasbag inflation prop open the atrium wall through sliding sleeve on the body, avoids drainage portion absorption atrium wall. But this kind of structure need insert the atrium after the sliding sleeve of back operation could make the gasbag inflation prop up atrium wall at the drainage tube, and it is inconvenient to use, and because sliding contact exists between sliding sleeve and the body, there is the clearance each other, and gas in the gasbag can slowly leak, even long-time back gasbag of using also can't fully prop up atrium wall through the extrusion, still can produce the drainage hole and block up, and gas leakage gets into the heart and also can cause very big potential safety hazard.
The utility model has the following contents:
technical problem to be solved

The technical scheme is as follows:
in order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a novel atrium attracts pipeline, is in including body and setting the drainage hole of body front end, the drainage hole has a plurality ofly the body front end interval is evenly arranged, between the drainage hole be equipped with the support ring on the body outer wall, the support ring with the body is coaxial, be equipped with the elastic membrane on the support ring, the elastic membrane with be equipped with the prefill chamber between the outer wall of body, follow on the body axial direction is equipped with the intercommunication piece, the intercommunication piece with be equipped with between the body outer wall with the through-flow groove of prefill chamber intercommunication, the body rear end be equipped with the body is the injection syringe that Y shape is connected, the through-flow groove with the injection syringe intercommunication.
The injection tube is used for being inserted into an atrium after the tube body is inserted into the atrium, water is injected into the liquid filling cavity through the through-flow groove, after the liquid filling cavity is injected with water, the elastic membrane expands under the action of water pressure to prop open the atrium wall around the drainage hole, the situation that the drainage hole is blocked due to contact with the atrium wall is prevented, water injection can be performed after the tube body is inserted into the atrium, operation is simple, and safety risks are avoided.
Furthermore, a sealing cap is detachably arranged at the top end of the injection tube, a rubber sealing layer is arranged on the sealing cap, the rubber sealing layer is used for inserting a needle of an injector, good sealing performance is achieved while water injection is guaranteed, the sealing cap can be detached from the injection tube, so that water in the liquid filling cavity can be discharged after drainage is completed, and the tube body can be conveniently taken out from an atrium.
Furthermore, the support rings are distributed at intervals along the axial direction of the tube body, so that the space around the drainage hole is completely expanded, and a good drainage effect is ensured.
Furthermore, the drainage hole sets up two adjacent between the support ring on the outer wall of body, the diameter in drainage hole is less than two adjacent interval between the support ring prevents on the support ring the elastic membrane is to when the water injection struts the drainage hole produces sheltering from.
(III) the beneficial effects are as follows:
compared with the prior art, the utility model discloses the beneficial effect who produces is: through set up the support ring on the body outer wall between body front end drainage hole, set up the elastic membrane on the support ring, set up the prefill chamber between the outer wall of elastic membrane and body, prefill chamber and syringe intercommunication can utilize the syringe to fill water in the prefill chamber after the body is inserted in the atrium, thereby make the elastic membrane inflation strut the atrium wall around the drainage hole, when preventing that drainage hole and atrium wall contact from resulting in the jam, easy operation avoids producing safe risk.
