Integrated safety lumbar puncture outfit

Abstract

The invention discloses an integrated safety lumbar puncture outfit. The integrated safety lumbar puncture outfit is formed by a puncture unit, a cerebrospinal fluid circulating unit, a safety protection unit, and a machine housing. The integrated safety lumbar puncture outfit is mainly applied to needed conditions that a cerebrospinal fluid pressure test which needs to perform lumbar puncture isperformed in clinic diagnosis and treatment processes, a cerebrospinal fluid sample is reserved to perform laboratory examination, and intrathecal injection is performed through subarachnoid space andthe like. Compared with a traditional lumbar puncture needle, the integrated safety lumbar puncture outfit is capable of realizing the cerebrospinal fluid pressure test and the intrathecal injectionin the same device, reserving the cerebrospinal fluid sample according to the need, and controlling a release speed of cerebrospinal fluid, thereby avoiding a cerebral hernia risk caused by uncontrollable rapid cerebrospinal fluid release in a lumbar puncture process, protecting life safety of a lumbar puncture patient, and simpler and more healthful in operation.

Description

technical field [0001] The invention relates to an integrated safety lumbar puncture device, which is mainly used in the process of clinical diagnosis and treatment for the pressure test of cerebrospinal fluid by lumbar puncture, the collection of cerebrospinal fluid samples for laboratory examination, and the need for intrathecal injection through the subarachnoid space, etc. Compared with the traditional lumbar puncture needle, it can realize the pressure test of cerebrospinal fluid, intrathecal injection, take cerebrospinal fluid samples as needed, and control the release speed of cerebrospinal fluid in the same device, so as to avoid the pressure of cerebrospinal fluid during lumbar puncture. Due to the risk of brain herniation caused by the uncontrollable and rapid release of cerebrospinal fluid, it protects the life safety of lumbar patients. It is more complete than traditional lumbar puncture needles, and the operation is simpler and hygienic. It can replace traditional...

Problems solved by technology

[0004] There are certain operational risks and disadvantages in the above process, and some risks are even fatal. First, the risk of infection. When using traditional puncture needles for lumbar puncture, because the structure is single and the system is not integrated, it is necessary to repeatedly pull out and insert the needle core during puncture. , and then connect the pressure measuring tube and the cerebrospinal fluid sample bottle, the operation time is long, the process is cumbersome, the cerebrospinal fluid is exposed for a long time, and the needle core is easily polluted when placed outside the body, thus increasing the risk of infection during the lumbar puncture of the patient; second, the risk of brain herniation, in When some patients with potential intracranial hypertension undergo lumbar puncture, because the structure of the traditional lumbar puncture needle has no protection measures to control the flow rate of cerebrospinal fluid, when the needle core is pulled out, the cerebrospinal fluid is released quickly due to the high intracranial pressure. The pressure difference between the cranial cavity and the subarachnoid space changes too quickly, which in turn may lead to a sudden foramen magnum hernia, causing the patient's respiratory and cardiac arrest, which is life-threatening; third, the doctor's misuse risk of injury, traditional lumbar For the puncture needle, after the inner core of the puncture needle is pulled out, the cerebrospinal fluid is retained and the pressure is measured, the needle core needs to be returned. Since the puncture needle is thin and the needle core is soft, there are certain difficulties in the process of returning the needle core, especially When the cerebrospinal fluid flow rate is too fast, the operation is often too tense, which in turn leads to difficulty in receiving the needle core. On the one hand, it leads to excessive cerebrospinal fluid loss, which increases the risk of postoperative headache for the patient. At the same time, due to the difficulty in receiving the needle core, it may cause the operator fourthly, the risk of cross-infection, due to the long stroke of lumbar puncture and the length of the needle body, there is a risk of iatrogenic stabbing before and after the operation, and there may be a risk of stabbing after the lumbar puncture. Leading to iatrogenic cross-infection, the puncture needle lacks anti-puncture protection measures

[0005] At present, there is still no new lumbar puncture system that solves the above clinical problems of traditional puncture needles at home and abroad.
