Problems solved by technology

If the cerebrospinal fluid leaks, it will affect the intracranial pressure, which will have a negative impact on the normal life of the human body, and the pressure of the cerebrospinal fluid cannot be measured normally, making the measurement results inaccurate
[0003] Chinese patent CN201595908U provides a lumbar puncture needle. A drainage tube is provided at the front end of the needle seat on the needle body. The inner cavity of the drainage tube communicates with the inner cavity of the needle. The lower end of the drainage tube is connected to the collection tube. The collection tube is provided with a scale line. The collection of cerebrospinal fluid has been realized, but because the cerebrospinal fluid itself is a viscous liquid, it is difficult for the cerebrospinal fluid to flow out, and the drainage tube is set at the front end of the needle seat on the needle body, which is not conducive to industrialization
Not only the cost of using a pressure gauge is high, but also the use of a switch and a tee is not conducive to the doctor’s simultaneous sampling, support and switch rotation in actual operation, and unstable support will increase the pain of the patient

Abstract

The invention belongs to the technical field of anesthesia puncturing, and particularly relates to a novel disposable subarachnoid space rotation type cerebrospinal fluid collecting, displaying and pressure measuring device. The novel disposable subarachnoid space rotation type cerebrospinal fluid collecting, displaying and pressure measuring device comprises a rotary collecting device and a pressure measuring device; an anesthesia spinal needle is connected with a lumbar puncture needle; the lumbar puncture needle is connected with the rotary collecting device; and the rotary collecting device is connected with the pressure measuring device. The rotary collecting device comprises a connecting end, a collecting tube fixedly connected with the connecting end and a collecting tube located at the lower portion of the collecting tube. The pressure measuring device comprises a pressure measuring tube; a breathable thin film is arranged at one end of the pressure measuring tube, a floating indicator is arranged inside the other end of the pressure measuring tube; the other end of the pressure measuring tube is connected with the collecting pipe; and scale marks are arranged on the inner wall of the pressure measuring tube. The novel disposable subarachnoid space rotation type cerebrospinal fluid collecting, displaying and pressure measuring device has the beneficial effects of being capable of accurately measuring the cerebrospinal fluid pressure and guaranteeing that cerebrospinal fluid does not escape in the pumping process; in addition, the cerebrospinal fluid can be pushed back; operation is simple and convenient; and the industrial production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of anesthesia puncture, in particular to a disposable subarachnoid space rotary cerebrospinal fluid collection, display and pressure measurement device. Background technique [0002] In recent years, combined lumbar epidural anesthesia has been widely used in clinical medicine in many countries. Anesthesia can extend the anesthesia time according to the needs of the operation, which overcomes the shortcomings of single anesthesia. The combined anesthesia puncture needle is a medical device used for combined lumbar epidural anesthesia, and it is formed by supporting an epidural puncture needle and a lumbar cone puncture needle. Existing epidural needles and lumbar puncture needles both include a needle sheath, a needle core, and a needle body. Whether it is a combined puncture needle or a single lumbar puncture needle, the cerebrospinal fluid is not easy to control during the lumbar puncture drainage process...
