Description

Technical Field

[0001] The invention relates to the technical field of silt clearing devices, and in particular to a cerebral silt clearing and blood silt clearing device. Background Art

[0002] The brain congestion blood removal device is a medical device that is mainly used to treat blood congestion or blood clots in the brain. The main function of this device is to quickly remove blood congestion in the brain and restore normal blood flow through mechanical or liquid extraction.

[0003] Announcement No. CN204582070U discloses a device for removing blood congestion from the epidermis of the head, which includes a positioning head cover, the positioning head cover is in a transparent semicircular shape, a blood drawing module can be slidably mounted on the positioning head cover, the blood drawing module includes an outer shell that can be adjusted up and down, the outer shell is mounted on the positioning head cover through a threaded lower twist ring, the lower part of the outer shell is equipped with a tightening block, the inner part of the outer shell is equipped with a needle tube, the needle at the lower part of the needle tube extends out of the tightening block, the inner part of the needle tube is equipped with an extraction rod, the upper part of the extraction rod is threadedly connected with an upper twist ring, and the upper twist ring can push the needle tube and the needle up and down. The device uses the lower part of the tightening block to press the blood congestion position on the head to facilitate the insertion of the needle; the extraction sleeve can move upward evenly and slowly through the threaded screw structure, so that the extraction process of blood congestion is more uniform and accurate.

[0004] However, in the actual working process of the device, it is impossible to complete the relative connection between the positioning hood and the head. The patient's head needs to be completely fixed when in use, which reduces the patient's comfort and increases the patient's fear. At the same time, the process is relatively cumbersome. If the patient's head shifts due to fear, it will cause the needle position to shift, and the pain will increase, resulting in a decrease in the effect of blood stasis extraction. It needs to be optimized and improved. Summary of the invention

Therefore, during the contact between the pressing plate 21 and the inclined plate 26, the baffle plate 24 and the inclined plate 26 will be driven to slide upward along the slide groove 25 under the combined action of the pressure and the inclined surface.

[0047] In one embodiment of the present invention, Figure 7 and Figure 8 As shown, the inner side of the sliding block 29 is provided with a thread, and the thread provided on the inner side of the sliding block 29 is meshed with the thread on the surface of the screw rod 28.

[0049] When the sliding block 29 slides along the groove plate 27 , it can drive the connecting plate 30 to change its angle and position, and can cooperate with the adjusting plate 31 to change its angle along the groove plate 27 .

[0050] During operation, the mounting plate 1 is first put on the patient's head, and then the worm 4 is rotated and the worm wheel 2 is driven to rotate along the placement groove 14 under the meshing action. In this process, the position of the guide groove A3 is driven to change, and the slider 6 is driven to slide inward along the frame plate 5 in cooperation with the convex rod 7, so that the three groups of splints 8 can be driven to be fixed on both sides of the patient's cheeks and the back of the head. Then, the angle of the connecting head 11 is adjusted. First, the screw rod 28 is rotated and the sliding block 29 is driven to slide along the groove plate 27 under the action of the thread. In this process, the angle and position of the connecting plate 30 can be driven to change, and at the same time, Cooperate with the adjusting plate 31 to change the angle along the groove plate 27, so as to drive the connector 11 to change its position, and then put the needle for extracting blood clots on the connector 11, press down or pull up the pull plate 37, at this time, the pull plate 37 will slide along the hole plate 35 through the guide rod B36, so as to drive the guide groove B38 to change its position, and under the cooperation of the guide groove B38 and the connecting column 34, the connecting column 34, the connecting plate 33 and the connector 11 can be driven to slide along the guide rod A32, so as to drive the needle to be advanced or retracted, so that it can be inserted into the blood clots to be extracted. The pump body 9 can then be started and the blood stasis can be extracted through the three-way pipe A10, the three-way pipe B13 and the connector 11. When the blood stasis enters the inner side of the anti-blocking cavity 16 along the three-way pipe B13, the solid blood clots in the blood stasis can be intercepted under the action of the interception plate 17 to prevent the blood clots from entering the inner side of the pump body 9 and causing blockage. When the blood clots gather too much on the interception plate 17, the check valve 15 on one side of the three-way pipe B13 that is in use is closed and the check valve 15 on the other side is opened. At this time, the blood stasis will be diverted under the action of pressure, and then the motor 18 is started. And drive the threaded rod 19 to rotate, at this time, the cleaning plate 20 will clean and push the blood clots accumulated on the surface along the intercepting plate 17, and the movement of the cleaning plate 20 will drive the pressure plate 21 to move. In the process of contact between the pressure plate 21 and the inclined plate 26, the baffle plate 24 and the inclined plate 26 will be driven to slide upward along the slide groove 25 under the combined action of pressure and inclined surface, and the leakage groove 23 will be exposed so that the blood clots can be discharged, thereby completing the self-cleaning work of the intercepting plate 17. After the pressure plate 21 is removed, the baffle plate 24 and the inclined plate 26 will slide downward along the slide groove 25 under the action of gravity and reset.
