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 tub

Embodiment 1

[0030] Embodiment 1: as Figure 4 As shown, the connecting end 13 is provided with threads for cooperating with the lumbar spine needle hub 10. The collection tube 14 is a hollow structure at both ends, and its front end passes through the connecting end 13 and extends into the lumbar spine needle hub 10. The end of the tube 14 is a structure that can be connected with the needle tube. The front end of the pressure measuring tube 20 is also connected with the end of the collection tube 14. An upper groove 17 is opened on the rotating upper port 16 at the lower end of the collection tube 14. The upper part of the collection tube 15 There is a lower groove 19 on the rotating lower port 18 of the rotating upper groove 17. When the rotating upper groove 17 is not connected with the lower groove 19, the cerebrospinal fluid pressure can be measured; the collecting tube 15 is a horizontal collecting tube 15; the side wall of the collecting tube 15 is provided with a sterile Cover 23,...

Embodiment 2

[0031] Embodiment 2: as Figure 5 As shown, the lower end of the collection pipe 14 is provided with a longitudinal collection pipe 15, and other structures are the same as in Embodiment 1.

Embodiment 3

[0032] Embodiment 3: as Figure 6As shown, the connecting end 13 is provided with threads for mating connection with the lumbar spine needle hub 10. The collection tube 14 is a hollow structure with one end open, and one end of the opening passes through the connecting end 13 and extends into the lumbar spine needle hub 10. The closed end is a free end; the upper end of the collection tube 14 is provided with an interface structure that can be connected with the needle tube. The tube 15 and the side wall of the collecting tube 15 are provided with a sterile cover 23, and the sterile cover 23 is placed in the sterile bag.

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, and in particular relates to a novel 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 punctur...
