Description
Technical Field
The invention relates to the field of drainage devices, in particular to a disposable puncture sampling drainage device.
Background
Lumbar puncture, also known as spinal cord puncture, is used to diagnose certain health conditions, and is performed on the lower back and lumbar spine. When lumbar puncture is performed, a needle is inserted between two lumbar bones (vertebrae), and a cerebrospinal fluid sample is collected. Cerebrospinal fluid wraps around the brain and spinal cord to protect it from injury.
Lumbar puncture may be helpful in diagnosing severe infections (e.g., meningitis), other central nervous system diseases (e.g., guillain-Barre syndrome and multiple sclerosis), hemorrhage, brain cancer, or spinal cord cancer. In some cases, lumbar puncture may be used to inject anesthetic or chemotherapeutic drugs into the cerebrospinal fluid.
While lumbar puncture (spinal puncture) is generally considered safe, there are indeed some risks, including:
headache is caused by penetration of fluids into nearby tissues after lumbar puncture in up to 25% of patients who have received lumbar puncture.
Headache usually begins within hours to two days after surgery and may be accompanied by nausea, vomiting and dizziness. Headache usually occurs while sitting or standing, and is relieved after lying down. Headache can last from several hours to a week or more after lumbar puncture.
Back discomfort or pain. After surgery, your lower back may feel pain or tenderness. Pain may spread to your back of the leg.
Bleeding. Bleeding may occur near the puncture site, or in rare cases, in the epidural space.
Brain stem hernia. Due to brain tumors or other space-occupying lesions, the pressure within the skull increases, and thus brain stem hernias may result after a cerebrospinal fluid sample is taken. To prevent this rare complication, a Computed Tomography (CT) scan or a magnetic resonance imaging (MR I) scan is typically performed prior to lumbar puncture to find any signs of placeholder lesions that lead to elevated intracranial pressure. Detailed neurological examination may also help to exclude significant placeholder lesions.
Therefore, the sampling is more convenient during the operation, the long-time operation is placed, the burden is increased to the operator, and the existing sampling tube cannot automatically rebound and reset, so that the medical staff needs more care when using the sampling tube, the inconvenient taking out after the sampling is prevented, the existing puncture measure comprises a disposable biopsy puncture needle, the sampling is less, and drainage cannot be placed at the same time; the cannula puncture needle can complete sampling only by simultaneously arranging biopsy sampling forceps, and a drainage and flushing integrated tube cannot be placed, so that a disposable puncture sampling and drainage device is needed.
