[0038] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 , a urinary catheter assembly convenient for bladder flushing is provided, which is mainly composed of a urinary catheter 100, an adapter plug 200 and a syringe 300. To realize the sealed connection of the syringe 300 and the urinary catheter 100, the adapter plug 200 with a specific structure is used, which is mainly composed of an integral molding circular truncated cone pipe body 210, a drainage pipe 220, a suction pipe 230 and a ball surface stop mechanism 240, and is integrally processed and formed by using plastic or aluminum alloy material.
[0039] Specifically, as shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 , the adapter plug 200 has a three-joint structure, which is respectively the front end of the circular truncated cone pipe body 210, the drainage pipe 220 communicated with the side wall thereof, and the suction pipe 230 arranged at the rear end. The front end of the circular truncated cone pipe body 210 is detachably connected with the tail end of the urinary catheter 100, which is used for sealingly connecting the urinary catheter 100 to ensure the stability of the sealing between the urinary catheter 100. The side wall of the circular truncated cone pipe body 210 is connected with the suction pipe 230, and the tail end of the circular truncated cone pipe body 210 is detachably connected with the syringe 300 through the suction pipe 230, which is used for inserting the syringe 300. The ball surface stop mechanism 240 adopts an automatic reset one-way valve structure design, which drives the ball surface stop mechanism 240 in the circular truncated cone pipe body 210 to open or close during the plugging connection of the suction pipe 230.
[0040] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when the urinary catheter assembly is used to flush the bladder blood clots, the nipple 301 of the syringe 300 is manually inserted into the suction pipe 230 until the front end thereof abuts and pushes the spherical check mechanism 240 in the suction pipe 230 to move forward, so that the spherical check mechanism 240 is separated from the front end port of the suction pipe 230, the suction pipe 230 and the frustoconical pipe body 210 are communicated, and the purpose of opening the spherical check mechanism 240 is achieved.
[0041] After the flushing is completed, the nipple 301 of the syringe 300 is manually pulled out of the suction pipe 230, and the spherical check mechanism 240 is reset under the pulling of the self-resetting spring 245, so as to block the front end port of the suction pipe 230, and the purpose of closing the spherical check mechanism 240 is achieved.
[0042] By arranging the spherical check mechanism 240, the first check plate 212 and the second check plate 222 in the adapter plug 200, the communication with the urinary catheter 100 and the syringe 300 is achieved, the liquid can be drawn out of the urinary catheter 100 by stretching the syringe 300, and the liquid can be discharged from the side wall drainage pipe by pushing back the syringe 100, which greatly facilitates the flushing of the bladder blood clots.
[0043] In some embodiments, as shown in Figure 1 and Figure 2 , the urinary catheter 100 mainly includes a straight pipe body, a first connector 101 and a second connector 102 arranged at the tail end of the pipe body, and a balloon 103 arranged at the front end of the pipe body. The pipe body, the first connector 101, the second connector 102 and the balloon 103 are integrally formed and are made of silicone material.
[0044] In use, the tail end of the first connector 101 can be detachably connected to the front end of the frustoconical pipe body 210. The specific structural design of the frustoconical pipe body 210 achieves the sealing and fixed connection with the first connector 101. The second connector 102 is arranged on one side of the first connector 101 and communicates with the balloon 103.
[0045] In some embodiments, as shown in Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , the frustoconical pipe body 210 is a conical structure with a small front end and a large tail end, and the diameter gradually increases from the front end to the tail end, which can be applied to two different connectors of the urinary catheter.
[0046] To improve the stability of the connection between the circular truncated cone tube 210 and the connector, and to avoid the connector from falling off the catheter 100, a plurality of first anti-skid protrusions 211 are arranged at intervals on the outer circumferential surface of the tail end of the circular truncated cone tube 210. One anti-skid protrusion 211 is used to insert the tail end of the circular truncated cone tube 210 into the corresponding catheter connector in an interference fit.
[0047] In addition, to prevent the backflow of urine extracted during the flushing process into the catheter, a first check plate 212 is arranged in the front end opening of the circular truncated cone tube 210. The first check plate 212 can be opened during the extraction of urine and closed under the extrusion of the inner urine during the discharge of urine.
[0048] By designing the circular truncated cone tube 210 of the adapter plug 200 as a hollow conical frustum structure, it can be applied to two types of connectors of the catheter 100, and can effectively improve the stability of the sealed connection between the adapter plug 200 and the catheter 100, and avoid the occurrence of urine leakage due to poor fixation.
[0049] In some embodiments, as shown in Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , the drainage tube 220 is a hollow conical frustum structure with a small outer end and a large inner end, and its diameter gradually increases from the front end to the tail end, which can connect urine drainage hoses of different diameters.
[0050] Similarly, to improve the stability of the connection between the drainage tube 220 and the urine drainage hose, and to avoid the urine drainage hose from falling off, a plurality of second anti-skid protrusions 221 are arranged at intervals on the outer circumferential surface of the outer end of the drainage tube 220. The second anti-skid protrusions 221 are used to insert the outer end of the drainage tube 220 into the corresponding urine drainage hose in an interference fit.
[0051] Similarly, to ensure that the urine can be stably extracted from the catheter, and to prevent the backflow of urine into the circular truncated cone tube 210 during the drainage process, a second check plate 222 is arranged at the communication between the inner end of the drainage tube 220 and the side wall of the circular truncated cone tube 210. The second check plate 222 can be in a closed state during the extraction of urine and in an open state under the extrusion of the inner urine during the discharge of urine, and its state is opposite to that of the first check plate 212.
[0052] In some embodiments, as shown in Figure 7 , Figure 8 and Figure 9As shown, in order to match the nipple 301 at the front end of the syringe 300, the diameter of the suction pipe 230 is designed to be smaller than the diameter of the frustum tube body 210, and a spherical reverse stop mechanism 240 is arranged at the connection between the front end and the frustum tube body 210. Under the push of the inserted nipple 301, the spherical reverse stop mechanism 240 realizes the blocking and opening of the suction pipe 230.
[0053] Wherein, in order to ensure the stability of the left and right movement of the spherical reverse stop mechanism 240, a plurality of limiting grooves 231 matched with the spherical reverse stop mechanism 240 are arranged on the inner circumferential wall of the front end of the suction pipe 230. A limiting block 244 matched with the limiting groove 231 is arranged on the spherical reverse stop mechanism 240, and the limiting block 244 is slidably arranged in the limiting groove 231.
[0054] In some embodiments, as shown in Figure 4 、 Figure 6 、 Figure 9 and Figure 10 In order to realize linkage with the syringe 300, the spherical reverse stop mechanism 240 adopts a specific structure design, which mainly includes an abutting pipe 241 and a spherical sealing block 242. The abutting pipe 241 and the spherical sealing block 242 are integrally processed by hard plastic material, stainless steel or aluminum alloy material.
[0055] The abutting pipe 241 is a hollow tubular structure, which is slidably embedded in the front end pipe body of the drainage pipe 220, the tail end is abuttingly connected with the inserted nipple 301 of the syringe 300, the front end is spacedly welded with the spherical sealing block 242, and a plurality of flow channel holes 243 are arranged on the circumferential wall of the front end pipe body connection, which are connected with the inner cavity of the frustum tube body 210.
[0056] In order to realize the sealing connection with the tail end pipe port of the frustum tube body 210, the spherical sealing block 242 is designed as a poor arc type spherical structure, the tail end spherical surface is connected with the front end of the abutting pipe 241, and the outer part of the tail end spherical surface can be sealingly abutted with the pipe port of the front end of the drainage pipe 220. So that the spherical reverse stop mechanism 240 can be tightly fitted at the pipe port of the front end of the suction pipe 230 during the release process, realizing the purpose of blocking the suction pipe 230.
[0057] In addition, the spherical reverse stop mechanism 240 also includes a plurality of limiting blocks 244 and a plurality of return springs 245. The plurality of limiting blocks 244 are arranged on the outer circumferential wall of the abutting pipe 241, and correspondingly arranged with the plurality of limiting grooves 231 on the inner circumferential wall of the drainage pipe 220.
[0058] The plurality of reset springs 245 are accommodated in the corresponding limiting grooves 231, the front end of the reset spring 245 is connected with the corresponding limiting block 244, and the other end is connected with the pipe body of the liquid discharge pipe 220. Through the elastic deformation of the reset spring 245, a pulling force can be always applied to the spherical sealing block 242, so that when the push force on the abutting pipe 241 is removed by pulling out the nipple, the abutting pipe 241 and the circular truncated cone pipe body 210 can be pulled back into the suction pipe 230 until the spherical surface of the spherical sealing block 242 blocks the pipe opening at the front end of the suction pipe 230.
[0059] The spherical reverse-stopping mechanism 240 designed in the structure can abut against the nipple 301 on the syringe 300 at one end, and the spherical sealing block 242 at the other end can drive the spherical sealing block 242 to block or open the pipe opening of the circular truncated cone pipe body 210 during the movement of the abutting pipe 241 pushed by the syringe 300, so that the suction pipe 230 is always in a blocked state when the syringe 300 is not inserted, and the leakage of urine is prevented.
