Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an anti-dislodgement epidural anesthesia catheter connector. Background Technology

[0002] Epidural anesthesia is a regional anesthesia method that achieves local anesthesia during surgery or childbirth by injecting anesthetic drugs into the epidural space to block the spinal nerve roots. An epidural anesthesia catheter connector is a medical device used to connect an epidural anesthesia catheter to a syringe or other infusion device. It plays a crucial role in epidural anesthesia, ensuring that anesthetic drugs are smoothly and safely infused from the syringe through the catheter into the epidural space.

[0003] In order to improve the efficiency of drug injection, existing epidural anesthesia catheter connectors use dual-port connectors. However, during drug injection, the dual-port connector will cause the drug to flow into the other port while being injected through one port, resulting in drug waste and reduced injection efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-dislodgement epidural anesthesia catheter connector to solve the problem mentioned in the background art where, during drug injection, the dual-port epidural anesthesia catheter connector may cause drug to flow into the other port, resulting in drug waste and reduced injection efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-dislodgement epidural anesthesia catheter connector, comprising a first connector tube, a second connector tube installed on the first connector tube, a cap fitted at one end of both the first and second connector tubes, a silicone column installed at the lower end of the first connector tube, a catheter inserted into the lower end of the first connector tube, a locking sleeve threaded onto the surface of the silicone column, a blocking mechanism provided inside the connection between the first and second connector tubes, the blocking mechanism comprising a torsion bar and a ball valve fixedly installed at one end of the torsion bar and located inside the first and second connector tubes, and a positioning mechanism cooperating with the torsion bar provided on the first connector tube.

[0006] Preferably, the locking sleeve has a tapered threaded hole inside, which matches the external thread of the silicone pillar.

[0007] Preferably, the torsion bar is rotatably mounted on the first connector pipe, the upper end of the ball valve has a first flow hole, and one side of the ball valve has a second flow hole.

[0008] Preferably, the other side of the ball valve, located symmetrically to the second flow hole, has a sealing structure. The first flow hole communicates with the inner cavity of the first connector pipe, and the second flow hole is connected to the channel of the first flow hole.

[0009] Preferably, the positioning mechanism includes a mounting block and a first positioning groove and a second positioning groove formed on the inner wall of the mounting block. The mounting block is mounted on the first connector pipe. A spring is installed inside the torsion bar, and a locking pin is installed at one end of the spring.

[0010] Preferably, the first positioning groove is formed on the top of the inner wall of the mounting block, and the second positioning groove is formed on the inner wall of the mounting block and its position is the same as the direction of the second flow hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the operator needs to inject medication through the first connector tube, simply rotate the torsion lever to align the ball valve's sealing structure with the second flow orifice, thus achieving a seal and ensuring that the medication flows only into the first connector tube, and vice versa. This simple operation effectively avoids drug mixing and waste, improving treatment accuracy. This design not only enhances the precision of drug injection but also significantly reduces the risk of operational errors, providing a more reliable technical guarantee for clinical treatment. Simultaneously, the ball valve's sealing structure design ensures no leakage during switching, further enhancing the safety and stability of catheter use.

[0013] 2. When the torsion bar rotates, the spring is compressed, and the locking pin also retracts. When it rotates to the appropriate position, the spring pushes the locking pin to reset. At this time, the locking pin enters the first or second positioning groove in the appropriate position to achieve precise positioning and ensure that the torsion bar is stably locked. This design further improves the reliability and safety of the connector and provides a more solid guarantee for clinical use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-3 An anti-dislodgement epidural anesthesia catheter connector includes a first connector tube 1, a second connector tube 2 installed on the first connector tube 1, and a cap 3 fitted at one end of both the first connector tube 1 and the second connector tube 2. The cap 3 can isolate bacteria and prevent foreign objects from entering when not in use, and can be removed directly for use when injecting drugs. A silicone column 4 is installed at the lower end of the first connector tube 1, and a catheter 5 is inserted into the lower end of the first connector tube 1. A locking sleeve 6 is threaded on the surface of the silicone column 4. The locking sleeve 6 rotates and tightly engages with the silicone column 4, effectively preventing the catheter 5 from slipping and ensuring a stable connection. The locking sleeve 6 has an anti-slip texture, making it easy for the operator to grip and adjust, improving the convenience and safety of medical operations. A blocking mechanism 7 is provided inside the connection between the first connector tube 1 and the second connector tube 2. With the setting of the blocking mechanism 7, when the operator injects drugs through the first connector tube 1, the blocking mechanism 7 blocks the second connector tube 2 to prevent the drugs from flowing in, and also avoids the residue of other drugs in the second connector tube 2. When it is necessary to inject drugs through the second connector tube 2, the blocking mechanism 7 can also block the first connector tube 1. The blocking mechanism 7 includes a torsion bar 71 and a ball valve 72 fixedly installed at one end of the torsion bar 71 and located inside the first connector tube 1 and the second connector tube 2. The first connector tube 1 is provided with a positioning mechanism 8 that cooperates with the torsion bar 71. With the setting of the positioning mechanism 8, when the blocking mechanism 7 needs to block the corresponding first connector tube 1 or second connector tube 2, the positioning mechanism 8 can fix the position of the torsion bar 71 and the ball valve 72 to prevent displacement during drug injection.

[0021] The locking sleeve 6 has a tapered threaded hole inside, which matches the external thread of the silicone column 4. The tapered threaded hole and the silicone column 4 can cooperate to achieve a tighter connection, enhance the locking effect, and ensure that the catheter 5 will not loosen due to external force during use, thereby further improving the stability and reliability of medical operations.

[0022] A torsion bar 71 is installed through and rotatably on the first connector tube 1. A first flow hole 73 is provided through the upper end of the ball valve 72, and a second flow hole 74 is provided on one side of the ball valve 72. By rotating the torsion bar 71, the ball valve 72 can flexibly switch the on / off state of the first flow hole 73 and the second flow hole 74 to ensure that the drug is accurately injected into the target catheter 5.

[0023] The other side of the ball valve 72, located symmetrically to the second flow hole 74, is a sealing structure. The first flow hole 73 is connected to the inner cavity of the first connector pipe 1, and the second flow hole 74 is connected to the channel of the first flow hole 73.

[0024] Specifically, during use, when the operator needs to inject medication through the first connector tube 1, they simply rotate the torsion bar 71 to align the sealing structure of the ball valve 72 with the second flow hole 74, thus achieving a seal and ensuring that the medication flows only into the first connector tube 1, and vice versa. This simple operation effectively avoids drug mixing and waste, improving treatment accuracy. This design not only improves the precision of drug injection but also significantly reduces the risk of operational errors, providing a more reliable technical guarantee for clinical treatment. Simultaneously, the sealing structure design of the ball valve 72 ensures no leakage during switching, further enhancing the safety and stability of the catheter 5. Furthermore, the durability and ease of maintenance of this device ensure long-term use and reduce the waste of medical resources.

[0025] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 3 and Figure 4 The positioning mechanism 8 includes a mounting block 81 and a first positioning groove 82 and a second positioning groove 83 formed on the inner wall of the mounting block 81. The first positioning groove 82 and the second positioning groove 83 facilitate fixing in different positions. The mounting block 81 is mounted on the first connector pipe 1. A spring 84 is installed inside the torsion bar 71. A locking pin 85 is installed at one end of the spring 84. The spring 84 can provide elastic force to the locking pin 85, so that the locking pin 85 is stably embedded in the positioning groove, ensuring accurate positioning of the torsion bar 71 and the ball valve 72 and preventing misoperation.

[0026] The first positioning groove 82 is formed on the top of the inner wall of the mounting block 81, and the second positioning groove 83 is formed on the inner wall of the mounting block 81 and its position is the same as that of the second flow hole 74.

[0027] Specifically, when the torsion bar 71 rotates, the spring 84 is compressed, and the locking pin 85 also retracts. When it rotates to the appropriate position, the spring 84 pushes the locking pin 85 to reset. At this time, the locking pin 85 enters the appropriate first positioning groove 82 or second positioning groove 83 to achieve precise positioning and ensure that the torsion bar 71 is stably locked. This design further improves the reliability and safety of the connector and provides a more solid guarantee for clinical use.
