Problems solved by technology

In addition, in the absence of a glass manometry tube, it may be necessary to roughly interpret intracranial pressure by counting cerebrospinal fluid drops
The above method is cumbersome to operate, and the long exposure time of cerebrospinal fluid increases the risk of infection. In some patients with intracranial hypertension, due to poor control of cerebrospinal fluid outflow, sudden foramen magnum hernia may occur, resulting in severe respiratory and cardiac arrest. complication
At present, there is no cerebrospinal fluid pressure measurement and release device that can solve the above problems at the same time in clinic

Embodiment approach 1

[0041] The cerebrospinal fluid pressure test and reading process of the device, as attached Figure 1-4 As shown, after the cerebrospinal fluid enters through the pressure detection pipeline (11), it contacts the pressure sensor (21) at the end of the pressure detection pipeline (11), and the pressure sensor (21) senses the pulsating pressure of the cerebrospinal fluid and converts the pressure into an electrical signal Incoming the control circuit (10), the control circuit (10) converts the signal into a numerical value and presents it on the display (20). When the intracranial pressure is increased by releasing cerebrospinal fluid or pressing the abdominal wall, the large vein in the neck, or the patient spontaneously coughing, etc. When a change occurs, the cerebrospinal fluid pressure value displayed on the display (20) changes accordingly under the control of the control circuit (10).

Embodiment approach 2

[0043] The cerebrospinal fluid retention process of the device, as attached Figure 1-5As shown, when the cerebrospinal fluid sample needs to be collected, press the liquid collection control button (5) on the casing (1), and the liquid collection control button (5) controls the work of the liquid control valve (23) through the connecting piece (15) , the liquid control valve (23) opens and releases the cerebrospinal fluid in the liquid intake line (13) into the liquid outflow line (3), and collects the cerebrospinal fluid, and the cerebrospinal fluid outflow measurement information on the liquid control valve (23) is converted into electrical signal transmission input into the control circuit (10), the control circuit (10) converts the signal into a numerical value and presents it on the display (20), and when the required amount of cerebrospinal fluid is retained, the liquid-taking control button (5) is released.

Embodiment approach 3

[0044] Embodiment 3: It is a preferred implementation process of the device of the present invention.

[0045] The device is applied to the process of human lumbar puncture cerebrospinal fluid pressure test and cerebrospinal fluid retention, as shown in the attached Figure 1-5 As shown, after the patient undergoing lumbar puncture is in a good position, select a suitable puncture site for puncture. After the puncture needle (7) of the device penetrates into the subarachnoid space of the spinal cord, the cerebrospinal fluid enters the liquid inlet pipeline (19) through the puncture needle pipeline. , then respectively enter the pressure detection pipeline (11) and the liquid extraction pipeline (13), the cerebrospinal fluid entering the pressure detection pipeline (11) contacts the pressure sensor (21) at the end of the pressure detection pipeline (11), the pressure sensor (21 ) feel the pulsating pressure of the cerebrospinal fluid, and convert the pressure into an electrical...

Abstract

The invention discloses a pressure monitoring and releasing device for cerebrospinal fluid. The pressure monitoring and releasing device is mainly applied to cerebrospinal fluid puncture needed in a clinical diagnosis and treatment process, for example, during lumbar puncture, pressure test of the cerebrospinal fluid is performed, a cerebrospinal fluid sample is retained for laboratory examination, and the like. The pressure monitoring and releasing device is characterized by replacing a traditional glass pressure testing tube in the lumbar puncture process; the required cerebrospinal fluid sample amount is retained by using a same device, pressure reading of the cerebrospinal fluid as well as visibility and quantization of the retained cerebrospinal fluid is realized, the operation flow is simplified, and puncture complication is avoided.

Description

technical field [0001] The invention relates to a clinically used cerebrospinal fluid pressure measuring and releasing device, which is mainly used in the pressure test of cerebrospinal fluid during lumbar puncture, and at the same time, samples of cerebrospinal fluid can be retained for laboratory examination, so as to realize the reading of cerebrospinal fluid pressure and the method of retaining cerebrospinal fluid Visualization and quantification, simplification of the operation process, belong to the field of clinical diagnosis and treatment operations. Background technique [0002] Clinically, lumbar puncture is a routine bedside diagnosis and treatment operation in neurosurgery, neurology, and pediatric neurosurgery. It is generally used for laboratory examination of cerebrospinal fluid samples and culture to help diagnose neurological diseases including nervous system infections. The puncture process It is often necessary to perform a pressure test of the cerebrospin...
