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 m...

Embodiment approach 1

[0047] Described device is applied to the lumbar puncture process of human body, as attached Figure 1-4 As shown, after the patient undergoing lumbar puncture is in a good position, select a suitable puncture site for puncture, and the operator holds the handle (2) of the device. The front of the puncture needle (24) slopes upwards, the puncture needle (24) passes through the skin, muscle, and vertebral body into the subarachnoid space of the spinal cord, and pulls the needle core pull-back mechanism backwards to the tail end of the slideway (3) with your fingers , the needle core end (6) of the needle core pull-back mechanism drives the needle core (7) to slide to the tail end, press the button (12) of the liquid release control mechanism, release the button (12) after seeing the cerebrospinal fluid flowing out, the puncture is completed, and then Perform cerebrospinal fluid pressure testing, cerebrospinal fluid sample collection, or intrathecal injection in the subarachnoid...

Embodiment approach 2

[0049] The cerebrospinal fluid pressure test and reading process of the device, as attached Figure 1-3 As shown, the puncture needle (24) of the device enters the subarachnoid space of the spinal cord, and by confirming that the button (12) of the liquid release control mechanism is pressed, after seeing that the cerebrospinal fluid flows out, the outflow channel is closed, and the connecting cap (23) is rotated. Then drive the fixed cap (22) and the puncture needle (24) to rotate, rotate the inclined surface of the head end of the puncture needle (24) to the direction of the head end of the subject horizontally, and then connect the pressure testing mechanism (27) to the cerebrospinal fluid pressure measuring tube (28) Or other pressure measuring devices, the one-way valve mechanism (31) located in the pressure testing mechanism (27) is opened, the cerebrospinal fluid passes through the inner cavity of the puncture needle (24), the "T" shaped pipeline (10), and the pressure t...

Embodiment approach 3

[0051] The cerebrospinal fluid retention process of the device is as attached figure 1 As shown, when the cerebrospinal fluid sample needs to be collected, the button (12) of the liquid release control mechanism is pressed, and the button (12) acts on the spring (11) through the moving block (13), so that the spring (11) is compressed, and the moving block ( The flow channel (14) in 13) communicates with the "T"-shaped pipeline (10), the cerebrospinal fluid passes through the lumen of the puncture needle, and the "T"-shaped pipeline (10) flows out through the outlet (15) of the liquid release control mechanism After the required amount of cerebrospinal fluid is retained, the button (12) is released, and the moving block (13) slides forward under the action of the spring (11), and the pipeline is closed.

Abstract

The invention discloses an integrated safe lumbar puncture device used clinically. The integrated safe lumbar puncture device is mainly applied to the conditions that cerebrospinal fluid puncture needs to be conducted in the clinical diagnosis and treatment process, for example, the cerebrospinal fluid pressure test is conducted during lumbar puncture as well as a cerebrospinal fluid sample is remained to perform laboratory examination. The integrated safe lumbar puncture device is characterized in that the traditional lumbar puncture needle can be replaced; the cerebrospinal fluid pressure test can be realized in the same device; the cerebrospinal fluid sample is remained according to the requirement and intrathecal injection is conducted; cerebral hernia caused by high cranial pressure excessive drainage in the lumbar puncture process can be avoided; the operation processes of sample retention, pressure test and intrathecal injection can be completed in the same device; the operationflow is simplified; puncture complications are avoided; and the safety of patients and operators is guaranteed.

Description

technical field [0001] The invention relates to a clinically used integrated safety lumbar puncture device, which is mainly used in the pressure test of cerebrospinal fluid during lumbar puncture, as well as taking samples of cerebrospinal fluid for laboratory examination, etc. It is characterized in that it can replace the traditional lumbar puncture Needle, can realize cerebrospinal fluid pressure test in the same device, take cerebrospinal fluid samples according to needs, intrathecal injection, realize sample retention, pressure test, intrathecal injection and other operations in the same device, avoiding the lumbar puncture process due to Cerebral herniation caused by high intracranial pressure and excessive drainage, simplifying the operation process, ensuring the safety of patients and operators, belongs to the field of clinical diagnosis and treatment. Background technique [0002] Clinically, lumbar puncture is a routine bedside diagnosis and treatment operation in ...
