Description

Technical Field

[0001] This invention relates to the field of drainage device technology, specifically a neurosurgical drainage device for preventing hematoma accumulation. Background Technology

[0002] In actual neurosurgical clinical practice, a large number of patients with cerebrospinal fluid (CSF) require anti-hemoptysis drainage to reduce intracranial pressure. Patients requiring long-term CSF drainage often use abdominal drainage to allow the CSF to be naturally absorbed in the abdominal cavity. However, current anti-hemoptysis drainage devices are not convenient for controlling and adjusting the drainage position of CSF in the abdominal cavity. Long-term stimulation of the peritoneum by CSF in the same area can easily lead to local tissue fibrosis and hyperplasia. Furthermore, they are not easy to automatically control and stabilize intracranial pressure. Patient turning over during sleep or being shaken by caregivers directly affects intracranial pressure stability and can easily cause CSF reflux, increasing the risk of infection. Additionally, they are inconvenient for staff to administer intracranial antihypertensive medications, as traditional direct injection methods can easily further increase intracranial pressure.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a drainage installation device to facilitate intracranial drug administration to patients. By using the solenoid valves on the drainage tube and the drug administration tube in reverse series with a switching power supply, it can be ensured that the drug can be effectively supplied to the intracranial cavity during administration. In conjunction with the drug administration decompression device, it also allows staff to decompress the intracranial cavity before administering intracranial drugs when necessary, avoiding the problem of rapid increase in intracranial pressure caused by drug administration under normal intracranial pressure, and effectively reducing safety hazards.

[0016] The use of a turning protection device can automatically detect when a patient is turning over or when the patient's head needs to be lifted for tasks such as wiping. If the patient's head cannot lie flat stably, the device can automatically detect and control the cessation of cerebrospinal fluid drainage. This avoids large changes in intracranial pressure caused by head shaking or lateral turning, and also prevents the problem of large amounts of cerebrospinal fluid reflux caused by frequent changes in intracranial pressure, thus reducing the risk of infection.

[0017] Using an abdominal drainage device allows for easy adjustment of the drainage position during abdominal drainage. Long-term fixed drainage can easily lead to local peritoneal fibrosis and hyperplasia, forming encapsulated cysts that hinder cerebrospinal fluid absorption. This structure uses an internal shielding tube for adjustment within the abdominal drainage tube, which can avoid friction on the abdominal cavity, further improving safety and patient comfort. At the same time, it uses a large-area external drainage hole, which is not easy to get clogged. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 10 As shown: This invention provides a technical solution: a neurosurgical anti-hemispheric drainage device, comprising a drainage mounting component 1, a drug delivery decompression component 2 mounted on the drainage mounting component 1, the drug delivery decompression component 2 being used to control auxiliary decompression during intracranial drug delivery; a turning protection component 3 mounted on the drainage mounting component 1; the turning protection component 3 being used to prevent pressure loss; an abdominal drainage component 4 mounted on the drug delivery decompression component 2; the abdominal drainage component 4 being used to adjust the drainage position; the drainage mounting component 1 includes: a drainage tube 101 and a fixing mounting ring 1011, the drainage tube 101 having a drainage passage hole; the fixing mounting ring 1011 being fixedly mounted on the drainage tube 101, and the fixing mounting ring 1011 having a ring of through holes; the ring of through holes on the fixing mounting ring 1011 being used for passing bolts to fasten to the skull.

[0022] The drainage installation component 1 further includes: a drain pipe 1012, a drug delivery pipe 102, and a rubber stopper 1021. The drain pipe 1012 is inserted into the drainage pipe 101. A solenoid valve is provided on the drain pipe 1012. The drug delivery pipe 102 is fixedly installed on the drain pipe 1012, and a solenoid valve is provided on the drug delivery pipe 102. The solenoid valves on the drain pipe 1012 and the drug delivery pipe 102 are connected in reverse series with a switching power supply. A rubber stopper 1021 is fixedly sleeved at the end of the drug delivery pipe 102. The drug delivery pipe 102 is connected to the drainage pipe. The drug delivery pressure reducing device 2 includes: an external tube 201 and a pressure-stabilizing solenoid valve 202, the external tube 201 being connected to the drain tube 1012; the pressure-stabilizing solenoid valve 202 being fixedly installed on the external tube 201; the external tube 201 being a flexible tube; the drug delivery pressure reducing device 2 also includes: a suction assist balloon 203, the suction assist balloon 203 being fixedly installed on the external tube 201, and the suction assist balloon 203 being an elastic rubber structure; the suction assist balloon 203 being fixedly installed on the drain tube 1012; pressing... The suction-assisted balloon 203 is used to aspirate cerebrospinal fluid. The drainage installation component 1 facilitates intracranial drug administration. A reverse-connected power supply is used on the solenoid valves on the drainage tube 1012 and the drug delivery tube 102. When the drug delivery tube 102 is opened, the drainage tube 1012 automatically closes, ensuring effective intracranial drug delivery. Combined with the drug delivery decompression component 2, it also allows for decompression of the intracranial cavity before drug administration, preventing rapid increases in intracranial pressure caused by administration under normal intracranial pressure, effectively reducing safety hazards. First, bend the external tube 201 near the pressure-stabilizing solenoid valve 202. The bend will close the external tube 201. Then, manually press the suction-assisted balloon 203 to contract, opening the solenoid valve on the drainage tube 1012 and closing the solenoid valve on the drug delivery tube 102. Releasing the suction-assisted balloon 203 allows it to naturally expand and aspirate cerebrospinal fluid for decompression.

[0023] The turning protection component 3 includes: a detection shell 301, an alarm buzzer 3011, a power-contact detection ring 3012, and a ball-head tube 302. The detection shell 301 is located outside the drain pipe 1012; the alarm buzzer 3011 is fixedly installed on the detection shell 301; the power-contact detection ring 3012 is fixedly installed inside the detection shell 301; the inner ring of the power-contact detection ring 3012 has an arc-shaped structure; the ball-head tube 302 is fixedly installed in the middle of the detection shell 301; the ball-head tube 302 is sleeved on the drain pipe 1012; a ball head is provided on the outer side of the ball-head tube 302; double-sided sponge adhesive is provided on the side of the detection shell 301; the power-contact detection ring 3012... The bottom has a through groove; the overturning protection component 3 also includes: a swing block 303 and a contact bulb 304, the swing block 303 is sleeved on the ball head provided on the outside of the ball head tube 302; the bottom of the swing block 303 is a lead counterweight structure; the bottom of the swing block 303 has a groove, and the contact bulb 304 is embedded in the bottom of the swing block 303; the contact bulb 304 is attached to the swing block 303; the overturning protection component 3 also includes: an insulating block 305, the insulating block 305 is fixedly installed in the through groove on the electrical detection ring 3012; the contact bulb 304 rolls and adheres to the insulating block 305; the electrical detection ring 3012, the swing block 303, the pressure regulating solenoid valve 202 and The alarm buzzer 3011 is connected in series with a power supply and incorporates a turning protection component 3. This allows for automatic detection of patient turning or situations requiring head lifting for tasks such as wiping. If the patient's head cannot remain stable in a flat position, the system can automatically detect and pause cerebrospinal fluid drainage. This avoids significant intracranial pressure fluctuations caused by head movement or lateral turning, preventing frequent intracranial pressure changes that could lead to large amounts of cerebrospinal fluid reflux and reducing the risk of infection. Furthermore, this design does not contact the cerebrospinal fluid during detection, enhancing safety. It allows for direct pausing of drainage with an audible alert, resulting in a more rational and efficient design. To enhance safety, especially for real-time monitoring of patients during sleep, and to prevent accidental closure of drainage, the double-sided sponge adhesive on the side of the detection shell 301 is attached to the patient's scalp. When the patient turns over, causing a change in head tilt, or gets up for wiping or other care, resulting in a significant change in head position, the swing block 303 remains vertical under gravity. At this time, the bulb 304 will be misaligned with the insulating block 305 and will instead be attached to the electrical detection ring 3012. This activates the circuit, controlling the stabilizing solenoid valve 202 to close, improving intracranial pressure stability and preventing excessive cerebrospinal fluid reflux or drainage.

[0024] In Example 2, based on Example 1, the abdominal drainage device 4 includes: an abdominal drainage tube 401 and a telescopic corrugated tube 4021. The abdominal drainage tube 401 is fixedly installed at the end of the external tube 201; the abdominal drainage tube 401 is a blind tube; the abdominal drainage tube 401 has six rows of external discharge holes 402; the telescopic corrugated tube 4021 is fixedly installed in the middle of the abdominal drainage tube 401, and the telescopic corrugated tube 4021 has a corrugated telescopic structure; the abdominal cavity... The drainage tube 401 is used for placement in the abdominal cavity; the abdominal drainage component 4 also includes: an adhesive pad 403, which is fixedly sleeved on the abdominal drainage tube 401; the adhesive pad 403 is provided with double-sided adhesive; the abdominal drainage component 4 also includes: a shielding tube 404, an internal adjusting rigid tube 405, and an internal discharge hole 406, the shielding tube 404 is slidably fitted inside the abdominal drainage tube 401; the end of the shielding tube 404 is fixedly installed with an internal adjusting rigid tube 406. 5. The inner adjusting rigid tube 405 is located inside the telescopic corrugated tube 4021; the shielding tube 404 has four rows of inner discharge holes 406, and the length of the four rows of inner discharge holes 406 is less than that of the six rows of outer discharge holes 402; the diameter of the four rows of inner discharge holes 406 is greater than that of the six rows of outer discharge holes 402. The use of the abdominal drainage component 4 makes it easy to adjust the drainage position during abdominal drainage. Long-term fixed drainage can easily lead to local peritoneal fibrosis and hyperplasia, forming encapsulated cysts that hinder the absorption of cerebrospinal fluid. At the same time, this structure uses the method of adjusting the shielding tube 404 inside the abdominal drainage tube 401, which can avoid friction in the abdominal cavity, further improve the safety of use and patient comfort, and the structure is more reasonable. At the same time, the use of large-area outer discharge holes 402 makes it less prone to blockage. The cerebrospinal fluid drainage position can be achieved by adjusting the inner discharge hole 406 to align with the area of ​​the outer discharge hole 402. The operation is simple and flexible.

[0025] The working principle of this embodiment is as follows: First, after inserting the abdominal drainage tube 401 into the abdominal cavity, it can be used with the adhesive pad 403 to attach external aids to increase stability. A ring of through holes on the fixing installation ring 1011 is used to pass bolts through and fasten it to the skull. At this time, the drainage tube 101 is inserted into the intracranial drainage by hand. The double-sided sponge adhesive on the side of the detection shell 301 is attached to the patient's scalp. If intracranial drug administration is required, the side of the external tube 201 near the pressure regulating solenoid valve 202 is bent first. The external tube 201 can be closed after bending. Then, the suction assistance balloon 203 is manually pressed to contract, which can directly control the drainage tube. The solenoid valves on tubes 1012 and 102 control the opening and closing of the solenoid valves on tubes 1012 and 102, respectively. At this point, the aspiration assistance balloon 203 is released. As the balloon naturally expands, cerebrospinal fluid can be aspirated. Decompression is then achieved by closing the solenoid valve on tube 1012 and opening the solenoid valve on tube 102. The syringe is then used to puncture the rubber stopper 1021 to administer the medication, thus preventing increased intracranial pressure. The double-sided sponge adhesive patch on the side of the detection shell 301 is then attached to the patient's scalp. When the patient is lying flat... The swing block 303 inside the detection shell 301 hangs naturally under gravity. At this time, the bulb 304, aided by its own weight, will also adhere to the insulating block 305. Conversely, if the patient turns over, causing a change in head tilt, or if the patient gets up for cleaning or other procedures, resulting in a significant change in head position, the swing block 303 will remain vertical under gravity. In this case, the bulb 304 will shift away from the insulating block 305 and adhere to the detection coil 3012. This activates the circuit, controlling the stabilizing solenoid valve 202 to close, improving intracranial pressure stability and preventing excessively rapid cerebrospinal fluid reflux or drainage. Simultaneously, the alarm buzzer 3011 will also be powered on to alert the patient that the change in body position exceeds the standard and needs to be adjusted in time. When adjusting the position of the shielding tube 404, which is the position for discharging cerebrospinal fluid, using the flexible bellows 4021, one can first pinch the bellows 4021 and the inner adjusting tube 405 with one hand. At this time, the inner adjusting tube 405 can be pushed from the outside to adjust its position. Then, pinch the inner adjusting tube 405 again after adjusting its position to adjust the position of the shielding tube 404. That is, by "sliding" the bellows 4021 on the inner adjusting tube 405, the inner discharge hole 406 is aligned with the area of ​​the outer discharge hole 402. The cerebrospinal fluid can be discharged using the adjustable inner discharge hole 406. The operation is simple and flexible, and the structure is simple and compact.
