Detailed implementation manners

[0021] The present disclosure will be described in detail below with reference to the exemplary embodiments in the drawings. It should be understood, however, that the present disclosure can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present disclosure more complete and to fully convey the concept of the present disclosure to those skilled in the art.

[0022] In the description of the present disclosure, it should be understood that the orientation or positional relationships indicated by the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present disclosure.

[0023] Such as Figures 1 to 3As shown, in an embodiment of the present disclosure, a blood perfusion exhaust device includes a mounting plate 100, an angle conversion mechanism 200, and a vibration mechanism 300. The angle conversion mechanism 200 includes a cantilever 210 fixed to the mounting plate 100, a rotating shaft 220 rotatably connected within the cantilever 210 and having one end extending from the front end of the cantilever 210, and a motor 230 mounted on the mounting plate 100 for driving the rotating shaft 220 to rotate. The vibration mechanism 300 includes a strip plate 310 fixedly connected to the front end of the rotating shaft 220 in the middle, a lower chassis 320 fixedly connected to the lower end of the strip plate 310, an upper chassis 330 slidably mounted on the upper end of the strip plate 310, a lower tray 340 mounted above the lower chassis 320, and an upper tray 350 mounted below the upper chassis 330. A plurality of vibrators 360 are installed between the lower chassis 320 and the lower tray 340 and between the upper chassis 330 and the upper tray 350. The lower chassis 320, the lower tray 340, the upper chassis 330, and the upper tray 350 are all provided with slot holes 370 extending from the edge to the center at the same position.

[0024] Before use, first place this embodiment at the required position through the mounting plate 100; then place the blood perfusion device 500 on the lower tray 340 and clamp it by the upper tray 350 and the lower tray 340. Control the rotating shaft 220 through the motor 230, and then control the blood perfusion device 500 to rotate to the required angle (such as the horizontal position or tilted 45°), and then start the vibrator 360 to vibrate for exhaust. The vibration can vibrate only one end or both ends simultaneously according to requirements. Since the angle is adjusted first and the angle is not large before vibration, and the angle remains unchanged during vibration, the wires of the vibrator 360 will not interfere with the smooth operation of the entire device. The slot holes 370 on the lower chassis 320, the lower tray 340, the upper chassis 330, and the upper tray 350 are used for the conduits at both ends when loading the blood perfusion device 500.

[0025] The angle conversion mechanism 200 further includes a brake cylinder body 240 mounted on the mounting plate 100. The telescopic rod 241 of the brake cylinder body 240 penetrates through the side wall of the cantilever 210 and a brake pad 242 is fixed to the front end. The brake pad 242 presses against the rotating shaft 220 at the longest stroke position of the telescopic rod 241. The brake cylinder body 240 can be an electric cylinder for easy electric control. The brake pad 242 can be made of rubber material to ensure the braking effect. The brake cylinder body 240 and the brake pad 242 can stably fix the entire rotating shaft 220, avoiding violent shaking or even rotation of the device due to the vibration of the vibrator 360, and also avoiding the violent transmission of the vibration effect to precision components such as the motor 230, ensuring the smooth operation of the entire device.

[0026] The shaft of the motor 230 is equipped with a driving pulley 231, and the rotating shaft 220 is equipped with a driven pulley 221. The driving pulley 231 and the driven pulley 221 are driven by a synchronous belt 232. An opening through which the synchronous belt 232 passes is formed in the side wall of the cantilever 210. Through the synchronous belt drive, while ensuring the accurate control of the rotation angle of the motor, the motor 230 and the rotating shaft 220 are not directly connected, achieving a better protection effect.

[0027] In addition, a number of bearing seats 222 are installed on the rotating shaft 220, and the bearing seats 222 are fixedly installed on the inner side surface of the cantilever 210 to ensure that the rotating shaft 220 can rotate smoothly in the bearing seats 222.

[0028] In addition, a sliding sleeve 331 is fixed to the edge of the upper chassis 330. The sliding sleeve 331 is slidably sleeved on the upper end of the strip plate 310. A fastening screw 332 is connected by screws to the outside of the sliding sleeve 331. The fastening screw 332 can be used to prevent the sliding sleeve 331 from sliding after being tightened. An anti - detachment strip 311 for preventing the sliding sleeve 331 from falling off is fixedly connected to the top end of the strip plate 310. Through the cooperation of the sliding sleeve 331 and the fastening screw 332, the screw can be tightened after adjusting the position and installing the hemoperfusion device 500, preventing the upper chassis 330 from moving during use.

[0029] A sleeve 361 is sleeved outside the vibrator 360. The two ends of the sleeve 361 are respectively fixedly connected to the lower chassis 320 and the lower tray 340, or respectively fixedly connected to the upper chassis 330 and the upper tray 350. The sleeve 361 serves as a connecting member between the chassis and the tray, and secondly, is used to sleeve the vibrator 360 to protect the vibrator and limit the installation position of the vibrator. The vibrator 360 can be an electric vibrator for easy control, and its wire can pass through the lower chassis 320 and the upper chassis 330.

[0030] As Figures 4 to 5 shown, in another embodiment of the present disclosure, the hemoperfusion device exhaust device further includes a control mechanism 400. The control mechanism 400 includes a housing 410, a control circuit arranged inside the housing 410, a pump body 430 arranged outside the housing 410. The mounting plate 100 is installed outside the housing 410. The pump body 430 is connected to the hemoperfusion device 500 through a pipeline. The control circuit is electrically connected to the motor 230, the brake cylinder body 240, and the pump body 430 respectively. In addition, a control button 450 and a display screen 470 can be provided on the front surface of the housing 410 to facilitate control and monitor the operation of the device through the display screen. A pipeline fixing groove 470 can also be provided on the side surface of the housing 410 for placing the pipeline connecting the hemoperfusion device 500.

[0031] This embodiment mainly replaces the conventional fixed perfusion cartridge mounting bracket with the angle conversion mechanism 200, vibration mechanism 300, etc. of the present disclosure on the basis of a common hemoperfusion machine, so as to realize the automatic exhaust of the hemoperfusion cartridge 500. The integration of the whole device is high, and it can monitor and automate the exhaust and blood purification processes by presetting or adjusting the parameters of the control circuit during use.

[0032] It should be understood that all of the above embodiments are exemplary rather than restrictive. Under the concept of the present disclosure, various modifications or deformations made by those skilled in the art to the specific embodiments described above should fall within the protection scope of the present disclosure.
