Description
Technical Field
The invention relates to a medical apparatus, in particular to a bubble removing device for assisting ECMO conduit connection.
Background
In the prior art, an Extracorporeal Membrane Oxygenation (ECMO) is an important support treatment means for patients with severe respiratory and circulatory failure, and uses Extracorporeal devices to replace or partially replace human lung and heart functions, so as to support life and strive for opportunities for heart and lung disease healing and function recovery. The ECMO system consists of a centrifugal pump, an oxygenator, a pipeline and a monitoring system, venous blood of a patient is drained from the body to the oxygenator outside the body through the centrifugal pump, and the venous blood is returned to the venous system or the arterial system after gas exchange is finished, and the ECMO system is commonly used for patients suffering from cardiogenic shock, acute cardiopulmonary failure and cardiopulmonary resuscitation caused by acute myocardial infarction, severe myocarditis and the like. ECMO techniques can significantly reduce mortality.
With the ECMO technique, there are two steps required to connect the vascular catheter to the extracorporeal circulation catheter during the procedure (the two catheters are sized to be insertably mated). The extracorporeal circulation catheter is filled with physiological saline, the blood vessel catheter is filled with blood, and the connector is required to be butted along the horizontal direction during connection operation. Because the pipe diameter is great, normal saline can partly overflow the oral area of pipe (have air admission oral area simultaneously) during the tube head of slope body circulation pipe, and blood can partly overflow the oral area of pipe (have air admission oral area simultaneously) during slope blood pipe tube head, and the butt joint is accomplished under the condition that air got into two oral areas and can inevitably have the air to remain in the pipeline and form the bubble, if the bubble gets into the human air embolism that can lead to along with blood circulation, serious person leads to the death. Therefore, the elimination of air bubbles is an indispensable operation procedure in the connection operation. As shown in fig. 1, the current method for eliminating bubbles is: at least two persons are needed to cooperate, one person uses two hands to respectively hold the extracorporeal circulation catheter tube head and the blood catheter tube head, the two tube heads are oppositely butted (sleeved) forcibly, the two tube heads are sleeved into the lower opening edges (a small gap is reserved on the upper opening edges) of the two tube heads, the other person is closely matched, the physiological saline is continuously injected into the small gap at the interface end to be closed, and the flowing physiological saline is kept to completely remove residual bubbles at the moment of closing the interface end. When the method is adopted to remove the bubbles, the residual bubbles attached to the tube wall are difficult to find in time, time and labor are wasted, difficulty and risk are high, repeated operation is needed for completion, and a bubble removing device for assisting ECMO (electron cyclotron resonance) tube connection is needed in clinical practice.

The invention adopts the following technical scheme: the device comprises a container which is provided with an upper end opening and can contain physiological saline, wherein a pair of alignment holes are arranged on the left side wall and the right side wall of the container, and the pair of alignment holes comprise a vascular catheter jack and an extracorporeal circulation catheter jack; the size of the orifice of the vascular catheter jack is matched with the size of the outer pipe diameter of the vascular catheter, and the size of the orifice of the extracorporeal circulation catheter jack is matched with the size of the outer pipe diameter of the extracorporeal circulation catheter. The orifice of the vascular catheter jack and the outer tube wall of the vascular catheter are of a movable liquid-tight matching structure, and the orifice of the extracorporeal circulation catheter jack and the tube wall of the extracorporeal circulation catheter are of a movable liquid-tight matching structure.
The principle and the operation steps are as follows: step 1, respectively inserting the vascular catheter and the extracorporeal circulation catheter into corresponding butt joint jacks to reduce bubbles, and keeping the pipe orifice in an inclined upward state as much as possible during insertion, and step 2, respectively holding the blood catheter and the extracorporeal circulation catheter with two hands, relatively approaching the two pipe orifices, and keeping the pipe orifice in an inclined upward state as much as possible during the process; and step 3: injecting normal saline from the upper opening of the container, wherein the injection amount of the normal saline is only required when the liquid level is close to the upper opening of the container, and the two pipe orifices are kept below the liquid level of the normal saline; step 4, slightly shaking the two pipe orifices to remove residual bubbles attached to the pipe walls as much as possible; step 5, holding the blood catheter and the extracorporeal circulation catheter respectively by two hands to carry out butt joint (sleeve joint); step 6: and removing the device which is kept at the connecting part after the butt joint is finished.
In one improvement, the container is of a conical shell construction.
In another improvement, the container is of a hemispherical shell structure.
In yet another improvement, the container is a bottomed cylindrical structure.
In a further improvement, the butt-joint jack is provided with a connecting sleeve extending outwards. The connecting sleeve increases the contact area of the sealing port, can enhance the liquid tightness of the butt joint jack and the inserted catheter (the vascular catheter and the extracorporeal circulation catheter), simultaneously ensures that the butt joint jack sealing port has enough ductility under the condition of no liquid leakage, and meets the requirements of position conversion of vertically or obliquely finishing bubble removal and transversely finishing butt joint of two catheter tube heads.
The invention has the following advantages: 1. the device of the invention provides an environment which can keep the two tube heads below the liquid level of the physiological saline, thereby ensuring that no air bubbles are generated when the catheter is connected and effectively avoiding the occurrence of air embolism complications; 2. the operation is simple and convenient, one-time butt joint can be successful, and repeated operation is not needed; 3. the labor is saved, and the operation can be finished by one person. 4. Simple structure, low cost and easy implementation and popularization.
