Description

Technical Field

[0001] The invention belongs to the technical field of drainage, in particular to an extracerebral ventricular drainage device for treating cryptococcal meningitis. Background Art

[0002] Pulmonary cryptococcosis is a subacute or chronic fungal lung disease caused by Cryptococcus, with approximately one million new cases worldwide each year and a mortality rate as high as 20%-70%. Cryptococcal meningitis causes approximately 152,000 cases and 112,000 deaths annually. External ventricular drain (EVD) plays a vital role in the treatment of cryptococcal meningitis: it rapidly reduces intracranial pressure, prevents brain herniation, and ensures brain tissue perfusion; provides a direct route for drug administration, increases local drug concentrations, and reduces systemic side effects; facilitates cerebrospinal fluid sampling and dynamic assessment of treatment efficacy; and effectively manages complications such as hydrocephalus. However, EVD requires strict aseptic technique and controlled drainage rate to prevent infection. Overall, EVD significantly improves patient prognosis, reduces mortality and neurological complications, and is a key treatment option.

[0003] For example, the utility model with publication number CN214388371U discloses an extracerebral ventricular drainage tube for treating cryptococcal meningitis, which relates to the field of medical auxiliary equipment and solves the problem of safety hazards caused by the difficulty in arranging the drainage tubes currently used in the treatment of cryptococcal meningitis. The key points of its technical solution are: it includes a winding drum, a drainage tube body is provided on the winding drum, and a liquid outlet port and a liquid inlet port are provided at both ends of the drainage tube body respectively, a disposable gauze is provided on the side of the drainage tube body close to the liquid inlet port, a fixed ring band is provided on one side of the disposable gauze, and a viscose end is provided on the other side of the fixed ring band, a connecting diaphragm is provided on one side of the outer wall of the viscose end, a connecting section is fixedly installed on one side of the outer wall of the fixed ring band, and an inner tightening ring piece is evenly arranged and fixedly installed on the upper surface of the connecting section; it achieves the function of arranging the drainage tube and also plays the role of fixing the end of the drainage tube, and has high stability in use.

[0004] During the drainage process of the above-mentioned device, if the cerebrospinal fluid drainage rate is abnormal (such as too fast or too slow), medical staff need to rely on manual monitoring and adjustment, and lack intelligent control functions. This not only increases the workload of medical staff, but also may cause inaccurate control of the drainage rate due to adjustment, thereby affecting the treatment effect. For example, a drainage rate that is too fast may cause a sudden drop in intracranial pressure, causing serious complications such as brain herniation; while a drainage rate that is too slow may result in failure to effectively relieve intracranial pressure, delaying the disease and affecting the accuracy and safety of treatment; at the same time, the design of the drainage tube interface of the existing device is often not perfect, which is prone to bacterial accumulation and increases the risk of infection.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figures 1 to 8 As shown, the present invention provides an external ventricular drainage device for treating cryptococcal meningitis, comprising a drainage bag 1, a drainage tube 2 fixedly arranged on the drainage bag 1, and further comprising:

[0036] The mounting ring 21 is fixedly mounted on one end of the drainage tube 2 and the drainage bag 1. A pressure sensor 211 is fixedly mounted inside the mounting ring 21. The mounting ring 21 passes through the dropper bottle 22.

[0037] An adjusting mechanism 3 is provided on the drainage tube 2 and is used to adjust the drainage speed of the drainage tube 2;

[0038] A support frame 4 is provided with a hook, and a dropper bottle 22 is hung on the support frame 4;

[0039] Among them, the adjustment mechanism 3 includes an installation box 31 that is sleeved on the drainage tube 2 and fixedly connected to the support frame 4, a tightening component 32 and a driving component 34 arranged inside the installation box 31, the tightening component 32 is used to squeeze the drainage tube 2, and the driving component 34 is used to adjust the distance between the tightening component 32 and the drainage tube 2. An insertion groove 311 is provided on the surface of the installation box 31, and a protective sleeve 312 is fixedly installed on one side of the insertion groove 311 located inside the installation box 31, and the protective sleeve 312 is in contact with the drainage tube 2.

[0040] Adopting the above scheme: when in use, the drainage flow rate is intelligently adjusted through the adjustment mechanism 3, thereby facilitating real-time detection of the patient's intracranial condition. During drainage, the drainage tube 2 is first passed through the insertion groove 311 on the installation box 31 so that it passes through the protective sleeve 312, and then fixed on the dropper bottle 22, and then the other end is plugged into the part where drainage is required to achieve drainage. During the drainage process, the pressure sensor 211 is used to achieve real-time detection of the patient's intracranial pressure, and then the driving component 34 is used to adjust the position of the pressing component 32, and the force of squeezing the drainage tube 2 is debugged, thereby achieving adjustment of the drainage speed.

[0041] like Figure 7As shown, the clamping assembly 32 includes rollers 321 arranged in a circular array inside the mounting box 31 at multiple positions, Y-shaped brackets 322 fixedly arranged on the central axes of the multiple rollers 321, fixed rings 323 fixedly mounted on the multiple Y-shaped brackets 322, and a rotating rod 324 fixedly arranged at the center of the Y-shaped bracket 322, the symmetrical sides of the rotating rod 324 are rotatably connected with rotating rings 325, and a rotating motor 326 for driving the rotating rod 324 to rotate is fixedly arranged on one end of the rotating ring 325, anti-slip grooves are provided on the outer wall of the roller 321, and the roller 321 is made of hard rubber, and the two fixing rings 323 are fixedly provided with connecting rods 33 on the side away from the insertion groove 311, and the connecting rods 33 are symmetrically distributed inside the mounting box 31.

[0042] The above scheme is adopted: the flow rate in the drainage tube 2 is adjusted by the tightening component 32. During the adjustment process, the driving component 34 is first used to adjust the tightening component 32 to the part close to the drainage tube 2, and the rotating motor 326 is used to drive the rotating rod 324 to rotate so that it rotates along the rotating ring 325, thereby driving the fixed ring 323 in the center to rotate synchronously. During the rotation process, the Y-shaped bracket 322 and the roller 321 are driven to rotate. During the rotation process, the roller 321 squeezes the drainage tube 2 to narrow the drainage path of the pipeline, thereby achieving the adjustment of the flow rate to make it better adapt to the patient's intracranial pressure.

[0043] like Figure 4 As shown, the drive assembly 34 includes a rack 341 fixedly arranged on the side of the two connecting rods 33 away from the insertion groove 311, a connecting plate 342 fixedly arranged on the rack 341, a gear 343 engaged with the rack 341, a center rod 3431 fixedly installed at the center of the gear 343 and a drive block 344 fixedly arranged at the center of the center rod 3431, the center rod 3431 is rotatably connected to the side wall of the installation box 31, a drive motor 345 is fixedly arranged on one end of the center rod 3431, and the drive motor 345 is fixedly connected to the installation box 31, and a T-shaped slider 3421 is fixedly arranged on one side of the two connecting plates 342 close to the inner wall of the installation box 31, and T-shaped slide grooves 313 are opened on the symmetrical sides of the installation box 31, and the T-shaped slider 3421 is slidably engaged with the T-shaped slide groove 313.

[0044] The above scheme is adopted: the adjustment of the tightening component 32 is achieved by utilizing the driving component 34, and the driving motor 345 is utilized to drive the driving block 344 to rotate, thereby driving the two symmetrical gears 343 on both sides to rotate synchronously, and the rotation of the gear 343 drives the rack 341 engaged with it to move, thereby causing the connecting plate 342 to move synchronously, driving the T-shaped slider 3421 to slide along the T-shaped groove 313, squeezing the connecting rod 33 to drive the rotating ring 325 close to or away from the drainage tube 2, and adjusting the humidity thereof according to the patient's intracranial pressure, so that the roller 321 abuts against the drainage tube 2, thereby achieving the debugging effect.

[0045] like Figure 3 As shown, a control terminal 35 is fixedly mounted on the mounting box 31 . The control terminal 35 includes a display screen 351 , a command input module 352 , an alarm 353 and a warning light 354 . The pressure sensor 211 is electrically connected to the control terminal 35 .

[0046] The above scheme is adopted: the intelligent detection of the entire device is realized by using the control terminal 35. During use, the patient's intracranial pressure is detected by using the pressure sensor 211 and transmitted to the control terminal, displayed through the display screen 351, and the result is transmitted to the storage module for storage, so that medical staff can detect when the patient's intracranial pressure exceeds or falls below the threshold range in the storage module, which indicates that the patient is in danger. At this time, the result can be transmitted to the control terminal 35, and the control terminal 35 controls the operation of the rotating motor 326 and the driving motor 345 to realize reasonable adjustment of the flow rate of the drainage tube 2, thereby facilitating the improvement of the patient's condition. If the patient's intracranial pressure is still outside the threshold after adjustment, the alarm 353 will sound an alarm, and the warning light 354 will flash continuously, so that medical staff can arrive in time to check and provide first aid to the patient, realizing intelligent detection and regulation, and reducing the pressure on medical staff.

[0047] The working principle and usage process of the present invention: When using this device, the system achieves intelligent monitoring and control of the entire device through the coordinated operation of the integrated pressure sensor 211 and the control terminal 35. The pressure sensor 211 is responsible for real-time monitoring of the patient's intracranial pressure and transmits the collected data to the control terminal 35 for analysis and processing. Based on the received intracranial pressure data, the control terminal 35 automatically adjusts the operating state of the clamping component 32 and the drive component 34. Specifically, the drive component 34 precisely adjusts the position of the clamping component 32 through the meshing transmission mechanism of the rack 341 and the gear 343, thereby controlling the squeezing force of the roller 321 on the drainage tube 2. This adjustment mechanism enables intelligent control of the drainage flow rate within the drainage tube 2, ensuring that the drainage speed matches the patient's intracranial pressure changes. To prevent the continuous squeezing of the roller 321, which may cause permanent deformation of the drainage tube 2 and thus affect its rebound performance and service life, the device is also equipped with a rotary motor 326. This motor can drive the multiple rollers 321 to rotate, thereby achieving indirect squeezing and adjustment of the drainage tube 2. This design not only effectively reduces the risk of deformation of the drainage tube 2, but also ensures the uniform distribution of the squeezing force, further improving the reliability and safety of the device. Through the above-mentioned intelligent adjustment mechanism, the device can monitor and adjust the drainage flow rate in real time, so that the patient's intracranial pressure is always maintained within the normal range, providing patients with more accurate and safe treatment guarantees. In addition, the design of the device fully considers the convenience and stability of clinical use. The combination of the high-precision monitoring of the pressure sensor 211 and the rapid response capability of the control terminal 35 ensures the efficient operation of the system in complex medical environments. At the same time, the indirect squeezing method of the roller 321 not only reduces the physical damage to the drainage tube 2, but also extends the service life of the device and reduces maintenance costs. Overall, the device provides an efficient and reliable solution for monitoring intracranial pressure and adjusting the drainage flow rate through intelligent and automated control methods, significantly improving the accuracy of medical operations and the patient's treatment experience.
