Description

Technical Field

[0001] The invention relates to the field of postoperative detection of sella nervosa in brain surgery, in particular to a cerebrospinal fluid leakage detector used after postoperative sella nervosa in brain surgery / after lumbar cistern retention. Background Art

[0002] Cerebrospinal fluid (CSF) leakage is a common and serious complication in brain surgery, especially after sellar region surgery. Cerebrospinal fluid leakage may not only prolong recovery time and increase the risk of complications, but may also threaten the patient's health. Therefore, timely and accurate judgment of whether cerebrospinal fluid leakage occurs after surgery is crucial to ensure patient safety. Existing methods for detecting cerebrospinal fluid leakage mainly rely on the clinical experience of doctors, but because the symptoms of cerebrospinal fluid leakage are similar to those of other exudates such as clear nasal discharge and sweat, traditional diagnostic methods are often prone to misjudgment, resulting in certain risks for doctors when handling them.

[0003] Traditional methods and equipment for detecting CSF leaks are as follows:

[0004] 1) Clinical symptoms and signs:

[0005] Clinical symptom observation: Patients may present with symptoms such as headache, nausea, vomiting, and neck stiffness. Postoperative cerebrospinal fluid leakage is often accompanied by aggravated headache, especially when standing or sitting;

[0006] Physical signs: such as neck tenderness, cerebrospinal fluid dripping, etc.

[0007] 2) Imaging examination:

[0008] CT (Computed tomography): CT scans can be used to check the location of cerebrospinal fluid leakage, such as the subarachnoid space, subdural space and other leakage areas;

[0009] MRI (magnetic resonance imaging): Especially enhanced MRI, can help doctors find the location and extent of cerebrospinal fluid leakage. MRI can clearly show the flow and accumulation of cerebrospinal fluid, helping to determine whether there is leakage;

[0010] Nuclear medicine examinations: such as cerebrospinal fluid tracer testing, in which tracers are injected into the site of cerebrospinal fluid leakage and its flow is tracked through radioactive isotope scanning to further confirm the site of leakage.

[0011] 3) Cerebrospinal fluid flow assessment method:

[0012] CSF flow tracing: The flow of CSF is tracked by injecting tracers (such as radioactive isotopes or calcium ions) to observe whether there are abnormal flow paths. This method can effectively locate the leakage area.

[0013] 4) High-resolution imaging:

[0014] Cisternography: A radioactive tracer is injected into the subarachnoid space or cisterns and the tracer's path is visualized using CT or SPECT (single-photon emission computed tomography) to determine if and where CSF is leaking.

[0015] 5) Molecular biology detection:

[0016] PCR test: In some cases, cerebrospinal fluid leakage may be accompanied by microbial infection. Detection of bacterial, viral or fungal DNA / RNA in cerebrospinal fluid by PCR (polymerase chain reaction) can help determine whether there is abnormality in the cerebrospinal fluid when infection is present.

[0017] 6) Analysis of patient medical history and surgical history:

[0018] Medical and surgical history: For postoperative patients, especially those who have undergone brain surgery, sellar region or other CSF-related surgery, the analysis of medical history information is crucial for the diagnosis of leakage. Combining the patient's surgical records, symptoms, signs and imaging examination results can better determine the possibility of CSF leakage.

[0019] The above-mentioned cerebrospinal fluid leakage detection equipment and methods are mostly qualitative tests, and the operation is complicated, relying on professional equipment and high-tech operations. This is not convenient for clinicians to use, especially in busy surgical environments. Moreover, most of these devices are highly professional and cannot be used by ordinary caregivers and patients' families. At the same time, traditional cerebrospinal fluid detection methods often lack effective disinfection methods, which may lead to cross-infection or contamination of equipment, further increasing the risks for patients and medical staff.

[0051] The detection principle of the detector includes the following:

[0052] 1.PH value test:

[0053] Cerebrospinal fluid (CSF): The pH of CSF is usually between 7.3 and 7.5, which is slightly alkaline;

[0054] Clear nasal mucus: The pH value of nasal mucus is relatively neutral, usually between 6.5 and 7.0;

[0055] Sweat: The pH value of sweat is generally slightly acidic, usually between 4.5 and 6.5.

[0056] Test method: Use pH test paper 164A to test the pH value of the leaked liquid. By comparing the pH ranges of different liquids, you can preliminarily determine whether the leaked liquid is cerebrospinal fluid, clear nasal discharge or sweat.

[0057] 2. Sugar content detection:

[0058] Cerebrospinal fluid (CSF): CSF contains relatively high glucose concentrations, usually 40-70 mg / dL;

[0059] Clear nasal mucus: The sugar content in nasal mucus is very low, almost negligible compared to cerebrospinal fluid.

[0060] Sweat: Sweat also contains very low levels of sugar and is similar to clear nasal mucus.

[0061] This embodiment also provides a method for using the above detector, comprising the following steps:

[0062] 1) Equipment preparation:

[0063] Install the leak detection module 1:

[0064] Make sure the body 11 and the display control panel 12 are properly connected;

[0065] Check the perforations at the bottom of the housing 11 to ensure they are not blocked;

[0066] Check the combined bracket, including the upper bracket 13 and the movable bracket 14, to ensure that they are firmly installed, the movable bracket 14 is connected to the upper bracket 13 through the pin shaft, and the limit bolts are fixed;

[0067] Install disinfection module 2:

[0068] Install the upper snap ring 21 in the middle of the body 11 to ensure a secure fit;

[0069] Connect the disinfection cover to the disinfection base 24, check the elastic pleated structure of the disinfection cover, and ensure that the cover body 22 can be freely extended and retracted;

[0070] The adjusting rod 26 is installed to ensure that it can adjust the telescopic length of the disinfection cover.

[0071] 2) Cerebrospinal fluid leakage detection:

[0072] Start the device:

[0073] Open the display control panel 12 and ensure that the device is in a state to be detected;

[0074] The detection tape 164 is passed through the paper release wheel 161, the perforation, the paper guide wheel 162, the transition wheel 166 and wound around the paper collection wheel 163 to ensure that the detection tape 164 is intact and not damaged;

[0075] Loading test tape 164:

[0076] The paper unwinding wheel 161 unwinds the detection belt 164;

[0077] Utilize the detector 17 to detect whether the mark on the detection belt 164 is in place;

[0078] When the positioning mark on the detection belt 164 is in place, the pH test paper 164A and the sugar test paper 164b on both sides of the positioning mark are aligned with the bottom groove 15 of the movable bracket 14, and the paper placing wheel 161 and the paper collecting wheel 163 stop at this time;

[0079] The leakage liquid to be identified is dripped onto the pH test paper 164A and the sugar test paper 164b of the test strip, or the groove 15 at the bottom of the movable bracket 14 is directly contacted with the leakage liquid, and the leakage liquid will penetrate from the groove 15 into the pH test paper 164A and the sugar test paper 164b;

[0080] Testing process:

[0081] After the device is started, the detection belt 164 will roll along with the paper-releasing wheel 161 and the paper-collecting wheel 163;

[0082] The test belt 164 is carried along to the position of the micro CCD 165, and the test results of the pH test paper 164A and the sugar test paper 164b are respectively color-recognized by the micro CCD 165;

[0083] The display control panel 12 will display the analysis results, and output the final identification results by integrating the detection values ​​of pH and sugar, roughly distinguishing whether the leaked fluid is cerebrospinal fluid, clear nasal discharge or sweat.

[0084] 3) Equipment disinfection:

[0085] Disinfection preparation:

[0086] After use, prepare the disinfection module 2 and ensure that the adjustment rod 26 is adjusted to a suitable position so that the disinfection base 24 is close to the movable bracket 14;

[0087] UV disinfection:

[0088] Adjust the disinfection cover so that it completely surrounds the bottom side of the body 11 to form a sealed disinfection area;

[0089] Start the ultraviolet disinfection lamp beads 25 to ensure that the bottom surface of the movable bracket 14 can be thoroughly disinfected by the ultraviolet lamp beads;

[0090] After disinfection is completed, turn off the UV lamp beads and retract the disinfection cover to prevent ultraviolet rays from irradiating people.

[0091] 4) Equipment storage and maintenance:

[0092] After each use, clean the outside of the body 11, especially the contact part of the test strip, to avoid contamination;

[0093] Regularly check whether the ultraviolet lamp beads of the disinfection base 24 are intact and replace them when necessary.

[0094] It is worth noting that the entire device is controlled by a general control system. Since the equipment matched with the control system is commonly used equipment and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
