Embodiment 1
[0047] Such as figure 1 As shown, a puncture drainage tube for cerebral hemorrhage, the bottom of the drainage tube goes deep into the brain, and the top of the drainage tube is connected to an extension tube 11 through a connector 10, and the extension tube 11 is connected to a drainage bag 12. Such as Figure 2-3 As shown, the drainage tube includes an inner tube 2 and an outer tube 1 coaxially arranged, and a plurality of support bars are arranged between the outer wall of the inner tube 2 and the inner wall of the outer tube 1, and the support bars are evenly arranged along the circumferential direction of the inner wall of the outer tube 1 to ensure that the inner tube Tube 2 and outer tube 1 are coaxial, and the diameter of the support bars should be as thin as possible. A drainage channel 101 is formed between the inner tube 2 and the outer tube 1. The bottom end of the outer tube 1 exceeds the inner tube 2, and the drainage channel 101 is closed by an inclined annular...
Embodiment 2
[0050] This embodiment is an improvement made on the basis of embodiment 1, its main structure is the same as that of embodiment 1, and the improvements are as follows: Figure 4-5 As shown, the bottom end of the outer tube 1 is fixedly connected with an arc-shaped sealing plate 105 that seals the drainage area 104. The surface of the arc-shaped sealing plate 105 forms an outwardly convex arc surface. A central hole for blood to enter the drainage area 104 . The setting of the arc-shaped sealing plate 105 forms a semi-closed drainage area 104 on the one hand, which can limit the position of the blood clot when breaking or injecting hemolytic drugs; To injure brain tissue and cranial nerves, the surface of the arc-shaped sealing plate 105 forms a circular arc surface, that is, a circular arc transition is performed on the spikes to prevent the spikes from piercing the brain tissue and cranial nerves.
Embodiment 3
[0052] This embodiment is an improvement made on the basis of embodiment 1 or embodiment 2, and its main structure is the same as that of embodiment 1 or embodiment 2. The point of improvement is that in embodiment 1, liquid volume is injected To control the displacement of the movable plunger 3, due to the small volume of the hydraulic expansion chamber 202, it is very difficult to control the volume of the injected liquid very precisely. Once the operation is improper, the movable plunger 3 will protrude from the drainage area 104, and even slide out of the hydraulic expansion chamber 202, and then stabbed the brain tissue and cranial nerves. Therefore, the bottom of the hydraulic expansion chamber 202 is fixedly connected with a block 203 around the inner wall. The block 203 can be a ring around the inner wall, and is fixedly connected with a limit block 304 around the top of the movable plug 3. In this embodiment, the movable plug 3 It consists of three parts, that is, the...
