For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0027] Example 1 Combine Figure 1-16 As shown, the present invention provides a multifunctional ventricular drainage tube fixing device, including a fixed body 1; also including a fixed bracket 2, a movable mechanism 3 and multiple adjustment mechanisms 4; the fixed bracket 2 is an inverted U-shape and is movably connected to the fixed body 1; the movable mechanism 3 is slidably set on the fixed bracket 2 and is detachably connected to the fixed bracket 2 for clamping the drainage tube body; multiple adjustment mechanisms 4 are slidably set on the fixed body 1 and are movably connected to the fixed bracket 2 for adjusting the height and angle of the fixed bracket 2 on the fixed body 1.
[0028] Furthermore, the fixed body 1 is a ring-shaped structure with an adjustable circumference, and is also provided with a snap assembly 7; the snap assembly 7 is used to adjust the circumferential diameter of the fixed body 1.
[0029] Specifically, one end of the fixed body 1 is fixedly connected to the snap assembly 7, while the other end is movably connected to the snap assembly 7. In use, the fixed body 1 is annular and designed to wrap around the head. By pulling the movable end, the circumference of the ring can be adjusted to accommodate patients with different head circumferences. The fixed body 1 is an adjustable ring-shaped structure with multiple tooth-shaped structures evenly distributed on the outer side of the ring. These structures interact with the adjustment mechanism 4 and the snap assembly 7 when wrapped around the head or other fixed positions, providing stable support and achieving the adjustability and adaptability of the overall structure. Materials used include medical-grade ABS plastic, carbon fiber composite, or titanium alloy. Two adjustment mechanisms 4 are symmetrically mounted on the outer wall of the fixed body 1 and connected to the bottom end of the fixed bracket 2. The fixed bracket 2 spans the top of the patient's head and has adjustment slots 21 defined in its bottom sidewall. By fitting the adjustment slots 21 over corresponding positions of the adjustment mechanisms 4, the adjustment mechanisms 4 can be adjusted with multiple degrees of freedom. The bottom of the movable mechanism 3 is provided with a through-slot that mates with the fixed bracket 2. This groove is used to clamp the drainage tube and slide on the fixed bracket 2 to accommodate the drainage tube, preventing compression and bending.
[0030] Furthermore, the movable mechanism 3 includes two movable blocks 31, a mounting sleeve 32, two positioning sleeves 33 and a connecting piece; the two movable blocks 31 are symmetrically and slidably mounted on the fixed bracket 2, and are detachably connected to the fixed bracket 2; the mounting sleeve 32 is a C-shaped structure, which is arranged at the front end of the movable block 31 and is used to clamp the drainage tube body; the two positioning sleeves 33 are arranged side by side at the top of the corresponding movable block 31; the connecting piece is used to connect the two positioning sleeves and limit the position of the movable mechanism on the fixed bracket.
[0031] Furthermore, the connecting member includes two positioning rods 34 and a rotating rod 35; the two positioning rods 34 slide through the two positioning sleeves 33 to connect the two positioning sleeves 33; the rotating rod 35 rotates through the two positioning sleeves 33 and is located between the two positioning rods 34, and is detachably connected to the two positioning rods 34, and is used to squeeze the two movable blocks 31 to clamp the fixed bracket 2.
[0032] The two movable blocks 31 are symmetrical and arranged facing each other with a gap between them. The fixed bracket 2 is set between the two movable blocks 31. By adjusting the two movable blocks 31 to move toward each other, the fixed bracket 2 can be clamped to limit the position of the entire movable mechanism 3. The positioning sleeve 33 is fixed to the movable block 31. The positioning sleeve 33 is an M-shaped structure as a whole, and a cylindrical sleeve is provided at the top slot of the M-shaped structure. A through hole is opened in the cylindrical sleeve along the axial direction. A through hole is also opened at the slot at the bottom of the M-shaped structure. Figure 9As shown. A positioning rod 34 extends forward and backward through the slot at the bottom of the M-shaped structure, while a rotating rod 35 extends forward and backward through the through-hole in the cylindrical sleeve. The movable block 31 and positioning sleeve 33 can be made of medical polymer materials such as polyamide and polycarbonate, while the positioning rod 34 and rotating rod 35 can be made of stainless steel or titanium alloy. The front end of the movable block 31 is fixedly connected to the mounting sleeve 32, which can be made of a combination of medical silicone and polyurethane, which is soft and durable.
[0033] Furthermore, the rear end of the positioning rod 34 is provided with a slot 341, and the front end is provided with a stopper 342; a first elastic member 343 is connected between the stopper 342 and the front positioning sleeve 33. The rear end of the positioning rod 34 is also provided with a blocking portion to prevent the positioning rod 34 from falling off. The slot 341 is provided on the outer wall of the positioning rod 34 and extends around the periphery. The positioning rod 34 passes through the first elastic member 343. When the movable mechanism 3 is not in use, the first elastic member 343 is naturally relaxed, and the slot 341 is located within the through hole of the positioning sleeve 33. When in use, the stopper 342 is manually pressed to compress the first elastic member 343, and the slot 341 extends from the through hole.
[0034] Furthermore, the rotating rod 35 has a fixing block 351 at its front end and an S-shaped fixing plate 352 at its rear end. Both ends of the fixing plate 352 are provided with engaging portions 353 that mate with the engaging slots 341. During use, the rotating rod 35 is rotated so that the two engaging portions 353 engage with the corresponding engaging slots 341 of the positioning rod 34. At this point, the first elastic member 343 presses the two movable blocks 31 toward each other, narrowing the gap between them and thereby clamping the bracket 2.
[0035] The working principle of the multifunctional ventricular drainage tube fixing device in this embodiment is as follows: the fixing bracket 2 is connected to the fixing body 1 through the adjustment mechanism 4, so that the fixing body 1 cooperates with the adjustment mechanism 4 to change the angle of the fixing bracket 2 on the fixing body 1 to adapt to different body positions of the patient. The movable mechanism 3 is used to clamp the drainage tube. By sliding the movable mechanism 3 on the fixed bracket 2, the position of the drainage tube can be adapted to achieve a suitable clamping state.
[0036] Among them, the specific principle of the movable mechanism 3 is: when in use, the two movable blocks 31 are clamped on the fixed bracket 2 and slid to the appropriate position, the first elastic member 343 is used to squeeze the two movable blocks 31 to expose the card slot 341, and the rotating rod 35 is rotated to rotate the fixed plate 352 and clamp the two clamping parts 353 into the corresponding card slots 341, so that the two movable blocks 31 clamp the fixed bracket 2, thereby fixing the drainage tube.
[0037] Example 2 On the basis of the first embodiment, the second embodiment provides a movable sleeve 36, which can extend the clamping length of the drainage tube, prevent the drainage tube from bending, and make the liquid flow smoother.
[0038] Specifically, the movable mechanism 3 further includes a movable sleeve 36 and a second elastic member 37 ; the movable sleeve 36 is slidably sleeved in the mounting sleeve 32 to clamp the drainage tube body; the second elastic member 37 is connected between the mounting sleeve 32 and the movable sleeve 36 .
[0039] Both the movable sleeve 36 and the mounting sleeve 32 have C-shaped structures with their open ends facing forward. The movable sleeve 36 is a slidable inner sleeve that is embedded in and can slide within the mounting sleeve 32. The movable sleeve 36 is made of medical silicone. The second elastic member 37 is a spring connected between the movable sleeve 36 and the mounting sleeve 32. Initially, it is in a compressed position and automatically resets when the pressure is released. Its combination with the movable sleeve 36 enables quick clamping and provides cushioning and protection for the drainage tube. It is made of TPE thermoplastic elastomer. A slide groove 321 is provided at the top of the mounting sleeve 32 along its length, and a guide rod 322 is provided inside along its length. The guide rod 322 extends through both sides of the top of the movable sleeve 36 and through the second elastic member 37. One side of the movable sleeve 36 is connected to the second elastic member 37, and the other side of the movable sleeve 36 can pass through the corresponding side of the mounting sleeve 32. Before the movable mechanism 3 is used, the second elastic member 37 is in a compressed state, and the movable sleeve 36 is locked in the mounting sleeve 32 by the fixing block 351 , so that the second elastic member 37 is locked. When in use, the fixing block 351 can be released.
[0040] Furthermore, a sliding block 361 is provided at the top of the movable sleeve 36 near the second elastic member 37 ; the sliding block 361 passes through the mounting sleeve 32 , and a groove 362 matching the fixed block 351 is formed on the sliding block 361 .
[0041] The sliding block 361 is fixedly connected to the movable sleeve 36 via a connecting shaft that extends through and slides within the chute 321. The sliding block 361 is located at the top of the mounting sleeve 32 and is made of ABS engineering plastic. A groove 362 is defined in the middle of the sliding block 361. Before the movable mechanism 3 is in use, the end of the fixed block 351 is positioned within the groove 362. The groove 362 includes a recessed portion that captures the end of the fixed block 351. This prevents the fixed block 351 from easily dislodging while within the groove 362, effectively locking the movable sleeve 36 within the mounting sleeve 32.
[0042] The working principle of the movable sleeve 36 in this embodiment is as follows: in use, the drainage tube is clamped in the movable sleeve 36 and the mounting sleeve 32, the rotating rod 35 is rotated, the clamping part 353 is clamped into the clamping groove 341, at the same time, the fixing block 351 rotates and leaves the groove 362 of the sliding block 361, the second elastic member 37 restores and releases the elastic force to push the movable sleeve 36, and then the movable sleeve 36 slides along the guide rod 322 until the second elastic member 37 completely restores to the natural state, and then the movable sleeve 36 slides along the drainage tube to clamp the drainage tube together with the mounting sleeve 32, so that the drainage tube is not easy to bend.
[0043] Embodiment three In order to make the device suitable for users of different body sizes, the multifunctional ventricular drainage tube fixing device in the application is also provided with an adjusting mechanism 4.
[0044] Specifically, the adjusting mechanism 4 comprises an adjusting block 41, a limiting member 42 and a limiting assembly 43; the adjusting block 41 is movably connected to the fixed body 1 and is used for adjusting the position of the fixed support 2 on the fixed body 1; the limiting member 42 is arranged on the adjusting block 41 and is in engagement with the outer side wall of the fixed body 1, and is used for limiting the fixed support 2 on the fixed body 1; and the limiting assembly 43 is arranged at the end of the adjusting block 41 away from the fixed body 1 and penetrates through the fixed support 2, and is used for limiting the height and angle of the fixed support 2.
[0045] It should be noted that the adjusting block 41 is a block structure movably connected to the fixed body 1, and the position can be adjusted by sliding the two adjusting blocks 41 together, realizing personalized positioning, and the adjusting block 41 is made of ABS engineering plastic. The limiting member 42 comprises a rotating shaft, a pressing piece, a torsional spring and a clamping piece 421, wherein the rotating shaft is inserted into the inside of the adjusting block 41 in the vertical direction, the torsional spring is located in the inside of the adjusting block 41 and is sleeved on the rotating shaft, the pressing piece is fixedly connected to the top end of the rotating shaft, and the clamping piece 421 is fixedly connected to the side wall of the torsional spring and can be engaged with the outer side wall of the fixed body 1, so as to lock the position of the adjusting block 41 and prevent sliding, and the clamping piece 421 is made of stainless steel. Two adjusting grooves 21 are formed in the bottom of the fixed support 2.
[0046] Further, the limiting assembly 43 comprises a supporting rod 431, a stop block 432, a gasket 433 and a third elastic member 434; the supporting rod 431 penetrates through the fixed support 2 and is connected with the adjusting block 41; the stop block 432 is threadedly sleeved on the other end of the supporting rod 431; the gasket 433 is slidably sleeved on the supporting rod 431 and is located outside the fixed support 2; and the third elastic member 434 is sleeved on the supporting rod 431 and is connected between the stop block 432 and the gasket 433.
[0047] The support rod 431 is fixedly connected to the outer wall of the adjustment block 41 and is made of stainless steel. The stopper 432 is made of brass or stainless steel. The gasket 433 is a circular thin sheet used to disperse pressure and prevent deformation of the fixed bracket 2. It is made of polytetrafluoroethylene. The third elastic member 434 is a spring structure, one end of which is connected to the gasket 433 and the other end is connected to the stopper 432, which improves the comfort of use and cushions the protective components. The adjustment slot 21 is mounted on the support rod 431. When in the fixed state, the third elastic member 434 is in a compressed state and squeezes the gasket 433, so that the gasket 433 and the adjustment block 41 clamp the fixed bracket 2.
[0048] Furthermore, both adjustment blocks 41 are movably connected to a U-shaped plate 5; an elastic band 6 is connected between the two U-shaped plates 5. The elastic band 6 is stretchable, increasing the flexibility of the overall structure, improving wearing comfort, and preventing the device from shaking. It is made of medical silicone or TPU elastic. The hollowed-out portion of the U-shaped plate 5 avoids the patient's ears, preventing them from being crushed. Furthermore, the top of the U-shaped plate 5 is provided with a threaded portion 51, each of which is fitted with a nut 52.
[0049] The working principle of the adjustment mechanism 4 in this embodiment is as follows: when in use, manually push the paddle to make the card 421 leave the outside of the fixed body 1, and at the same time, manually move the adjustment block 41 to make the fixed bracket 2 rotate. After releasing the hand, the torsion spring recovers and drives the card 421 to be re-stuck on the fixed body 1, and the stopper 432 is rotated to move the stopper 432 outward. At this time, the pressure of the third elastic member 434 on the gasket 433 is reduced, and then the fixed bracket 2 can be manually moved or rotated, and then the stopper 432 is rotated to make the third elastic member 434 squeeze the gasket 433 to lock it.
[0050] Specific application cases The multifunctional ventricular drainage tube fixation device is used for patients with cerebral hemorrhage or cerebral infarction who may require ventricular drainage to relieve intracranial pressure. This device ensures the stable position of the drainage tube, preventing poor drainage or infection risks caused by accidental movement. It is also used for patients recovering from surgery. After craniotomy or other surgeries involving brain tissue manipulation, patients typically require a period of close observation and treatment, including continuous cerebrospinal fluid drainage. The use of this fixation device helps improve patient comfort and reduces the workload of medical staff who frequently adjust the drainage tube.
[0051] The specific operation process of the multifunctional ventricular drainage tube fixing device when in use is as follows: Pre-adjust the buckle assembly 7 according to the patient's head circumference so that the fixing body 1 can comfortably surround the patient's head; fit the fixing body 1 to the patient's head, adjust it to the appropriate position and tighten the buckle assembly 7 to ensure that the entire device is stable and not prone to slipping; The height and angle of the fixing bracket 2 are adjusted by the adjustment mechanism 4 (including the adjustment block 41, the limiter 42, and the limit assembly 43) to suit the optimal insertion path of the drainage tube and the position of the fixing point. The selected height and angle are locked using the support rod 431, the stopper 432, and other components to ensure that the fixing bracket 2 is in an ideal state. Slide the movable mechanism 3 to the specific position where the drainage tube needs to be clamped, and use the rotating rod 35 to control the two positioning rods 34 to squeeze the movable block 31 inward, thereby firmly clamping the fixed bracket 2; adjust the C-shaped structure of the mounting sleeve 32 so that its opening is aligned with the drainage tube, and then push the movable sleeve 36 to clamp the drainage tube, relying on the elastic force provided by the second elastic member 37 to maintain close contact.
