Three Way Stopcock useful in the medical field, where an arm or channel is attached to an intravenous catheter or needle, while the other arm is used to administer intravenous fluids.



The goal is to achieve a three-way stopcock with excellent functionality, thereby achieving improvements in the way the arm or channel is associated with the intravenous bottle or container containing the therapeutic product. Another purpose is to better adapt the plug valve to the needs of the patient.





Three-way stopcocks are widely used in the medical and health fields for administering various products such as serum, nutrients and drugs through intravenous catheters. Patients with dementia and other coexisting pathological and cardiovascular problems are those who most need this stopcock to infuse one or more intravenous drugs simultaneously.



The utility model patent describes a three-way stopcock, which is characterized in that two secondary arms or paths emerge from the core of the atomic nucleus forming an orthogonal elbow along its trajectory.



Because the drugs and nutrients administered to a patient intravenously are solutions consisting essentially of liquid solid microelements, these microelements may deposit on the walls of the arms or channels, thereby impairing the full flow of fluid. Therefore, the presence of orthogonal elbows in the plug valves described in the aforementioned patents makes it difficult to eliminate the blocking of arms or channels. This problem has a negative impact on intravenous treatment, as drugs delivered to patients need to be managed within a specific time period.



Another problem raised by previously described plug valves with orthogonal elbows is reduced flexibility. For example, in situations where a medical staff needs to manipulate an arm or channel, such as changing an intravenous container or bottle containing a venous treatment product or disconnecting an auxiliary line from a main catheter, the main arm connection may be damaged. Intravenous catheters, which affect the supply of these products. Because the primary arm is directly connected to a catheter previously inserted into the patient's vein, any manipulation of the secondary arm can severely affect the venous connection, creating a pressure leak. Therefore, in view of this problem, it is desirable to have a three-way plug valve in which the jib is flexible.



In view of the previously outlined occlusion issues in secondary arms or channels and their reduced flexibility, improved three-way plug valves have been developed to address and meet these issues. In addition, due to this newly designed construction, the plug valve of the present invention provides greater flexibility. As a result, health personnel can operate the jib more easily and safely. If it acts on the auxiliary arm or route, it will not affect the main arm or channel. In this way, the secondary arm or path can be moved with greater freedom, so the intravenous treatment will not cause damage to the patient. In this way, the present invention solves problems such as pressure leakage.



The three-way sanitary plug valve developed by the present invention solves the aforementioned blocking problem on the basis of eliminating the orthogonal trajectory of the jib and replacing it with a curved trajectory.



According to a first object of the present invention, a three-way stopcock is a three-way stopcock composed of a cylindrical core or a body having a stopper or plug processed by a handle inside, the core converging on a main swing arm. The catheter is inserted into the patient's vein and there are two auxiliary arms or channels that receive other catheters that provide drugs or therapeutic fluids. The two auxiliary arms are diametrically opposed and are out of phase with respect to the main arm. Cross, because these auxiliary arms are characterized by an initial bend, are flexible and have a high elastic index, and then continue to remain clearly parallel to each other in their final part.



Therefore, like the intravenous catheter, the two connecting catheters of the plug valve's forearm also extend significantly parallel and are oriented towards the bedside of the patient undergoing intravenous treatment. This is the most advantageous direction, as bottles or containers containing medicines or nutrients are usually located on the patient's head.



The curvature and flexibility of the initial portion of the secondary arm prevents the secondary arm from becoming blocked, so intravenous infusion therapy is more effective because the volume of drugs and nutrients to be injected takes place within the required time. In addition, the initial section has a high elasticity index, so the ability to return to its initial position is greater, allowing the secondary arm to be used with greater safety.



Accordingly, the present invention is implemented, and the stopper or stopper located in the core or body cavity has an apparently “V” -shaped internal structure to allow the treatment fluid to pass through at the same time, while allowing fluid to flow. One of the auxiliary arms shuts off the flow to the other, and even shuts off the flow to the two auxiliary arms when needed.



Therefore, another implementation of the present invention is that the main arm and the jib will be made of medical grade polymer or plastic.
