Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-4 The utility model provides a technical solution, a lumbar cistern drainage medication device for children, comprising a fluid bag 1 and a speed control mechanism 4, a surface side of the fluid bag 1 is connected to a drainage tube 2, a surface side of the fluid bag 1 is provided with a liquid taking mechanism 3, and a surface side of the drainage tube 2 is provided with a speed control mechanism 4;
[0020] The speed control mechanism 4 includes a speed controller body 401, a micro motor 402, a speed meter 403, a screw rod 404, a first slider 405, a second slider 406, a first clamp 407 and a second clamp 408. The speed controller body 401 is connected to one side of the surface of the drainage tube 2, the micro motor 402 is arranged inside the speed controller body 401, the speed meter 403 is arranged inside the speed controller body 401, the screw rod 404 is connected to one side of the surface of the micro motor 402, the first slider 405 is threadedly connected to one side of the surface of the screw rod 404, the second slider 406 is threadedly connected to one side of the surface of the screw rod 404, the first clamp 407 is fixedly connected to one side of the surface of the first slider 405, and the second clamp 408 is fixedly connected to one side of the surface of the second slider 406. , the first clamping block 407 and the second clamping block 408 are set. When in use, first set a suitable drainage speed through the speed controller body 401. During the drainage process, the speed meter 403 monitors the flow rate in the drainage tube 2 in real time. When the actual flow rate measured by the speed meter 403 does not match the set value, the micro motor 402 is started, so that the micro motor 402 drives the screw rod 404 to rotate. Since the first slider 405 is restricted by the first clamping block 407 and cannot rotate, and the second slider 406 is restricted by the second clamping block 408 and cannot rotate, the screw rod 404 drives the first slider 405 and the second slider 406 to move relative to each other along the direction of the screw rod 404, and the first slider 405 and the second slider 406 drive the first clamping block 407 and the second clamping block 408 to move relative to each other, so that the first clamping block 407 and the second clamping block 408 adjust the flow rate to the set value by clamping or loosening the drainage tube 2, thereby achieving the purpose of controlling the drainage speed.
[0021] Furthermore, the micro motor 402 is electrically connected to the tachometer 403 , and the threads at both ends of the screw rod 404 are in opposite directions. Through the setting of the micro motor 402 , when in use, the micro motor 402 can provide power for the rotation of the screw rod 404 , and the micro motor 402 can provide support for the screw rod 404 .
[0022] Furthermore, the first clamp block 407 abuts against the drainage tube 2, and the second clamp block 408 abuts against the drainage tube 2. Through the arrangement of the first clamp block 407 and the second clamp block 408, when in use, the first clamp block 407 and the second clamp block 408 cooperate with each other to adjust the drainage speed of the drainage tube 2, thereby ensuring the stability of the drainage speed during the drainage process.
[0023] Furthermore, the drainage tube 2 is arranged in the middle position between the first clamp block 407 and the second clamp block 408, and the detection direction of the speed meter 403 is facing the drainage tube 2. Through the setting of the speed meter 403, when in use, the speed meter 403 can monitor the change of the flow velocity in the drainage tube 2, so that the flow velocity can be adjusted according to the feedback data.
[0024] Furthermore, the liquid collection mechanism 3 includes a liquid collection tube 301, a stopper 302, a protective shell 303, a button 304 and a disinfection lamp 305. One side of the surface of the fluid effusion bag 1 is connected to the liquid collection tube 301, and the other end of the liquid collection tube 301 is sealed and connected to the stopper 302. One side of the surface of the liquid collection tube 301 is connected to the protective shell 303, and one side of the surface of the protective shell 303 is installed with a button 304. A disinfection lamp 305 is arranged inside the protective shell 303. Through the arrangement of the liquid collection tube 301, the stopper 302, the protective shell 303, the button 304 and the disinfection lamp 305, when in use, when liquid needs to be collected for inspection, first use a puncture needle to insert the inside of the liquid collection tube 301 through the stopper 302 to take a sample, and press the button 304 while taking a sample, so that the button 304 controls the disinfection lamp 305 to start, so that the disinfection lamp 305 emits ultraviolet rays to disinfect the liquid collection tube 301 and the stopper 302, so as to avoid contamination during sampling, thereby increasing the risk of intracranial infection.
[0025] Furthermore, the button 304 is electrically connected to the disinfection lamp 305, which is an ultraviolet lamp. Through the setting of the disinfection lamp 305, when in use, the disinfection lamp 305 can disinfect the inside of the protective shell 303 by emitting ultraviolet rays, thereby reducing the possibility of external contamination.
[0026] Working principle: First, the speed controller body 401 is used to set a suitable drainage speed. During the drainage process, the speed meter 403 monitors the flow rate in the drainage tube 2 in real time. When the actual flow rate measured by the speed meter 403 does not match the set value, the micro motor 402 is started, so that the micro motor 402 drives the screw rod 404 to rotate. Since the first slider 405 is restricted by the first clamping block 407 and cannot rotate, and the second slider 406 is restricted by the second clamping block 408 and cannot rotate, the screw rod 404 drives the first slider 405 and the second slider 406 to move relative to each other along the direction of the screw rod 404. The first slider 405 and the second slider 406 move relative to each other along the direction of the screw rod 404. 406 drives the first clamp block 407 and the second clamp block 408 to move relative to each other, so that the first clamp block 407 and the second clamp block 408 adjust the flow rate to the set value by clamping or loosening the drainage tube 2, thereby achieving the purpose of controlling the drainage speed. When it is necessary to take liquid for inspection, first use a puncture needle to insert the inside of the liquid collection tube 301 through the plug 302 to take a sample, and press the button 304 while taking a sample, so that the button 304 controls the start of the disinfection lamp 305, so that the disinfection lamp 305 emits ultraviolet rays to disinfect the liquid collection tube 301 and the plug 302, so as to avoid contamination during sampling, thereby increasing the risk of intracranial infection.
