Problems solved by technology

[0003] Generally, the extraction needle that has extracted the liquid is firmly sealed in a vacuum measuring cup for testing by using the tympanic membrane to form a double guarantee. Since the tympanic membrane has an "X"-shaped hollow structure, when the tympanic membrane passes through the difference between the internal and external vacuum, it moves upward in the measuring cup and approaches the extraction needle. When the needle is removed, it will change the radian of its own "X"-shaped hollow structure in a bulging shape, so that the hollow opening will be concentrated and elongated in the shape of an arrow toward the needle of the extraction needle, causing the hollow opening in the middle of the bulge to extend infinitely. , drill into the extraction needle, it is easy to cause the "X"-shaped edge to be unable to seal at the needle head of the extraction needle

Embodiment 1

[0027] Such as Figure 1-Figure 3 As shown, the present invention provides an integrated device for extracting and inspecting cerebrospinal fluid in neurology department. The needle 3 is fixedly connected, the bottle cap 2 is screwed on the measuring cup 4, and the tympanic membrane 5 is arranged inside the measuring cup 4, and the measuring cup 4 includes a cup bottom 41, a frame 42, a booster body 43, a cotton filling room 44, a side buckle 45, the cup bottom 41 is fixedly connected with the tympanic membrane 5 through the side buckle 45, and welded to the frame 42, the frame 42 is socketed and connected with the cotton filling room 44, and the cotton filling room 44 is equipped with a booster body 43 The booster body 43 includes a rotating shaft 431, an exchange fork 432, a card holder 433, a spring 434, a connecting rod 435, and a fixed seat 436. The rotating shaft 431 is fixedly connected to the connecting rod 435, and is provided with an exchanging fork 432. A bracket 4...

Embodiment 2

[0029] Such as Figure 4-Figure 7 As shown, on the basis of Embodiment 1, the present invention combines the mutual cooperation of the following structural components. The card holder 433 includes a string handle 331, a buckle 332, a guide bag 333, a claw guard 334, and an elastic belt 335. The string The handle 331 is hingedly connected with four claws 334 through the buckle 332, and the middle part is sleeved and connected to the connecting rod 435. The claws 334 are fixedly connected with guide packs 333, and the guide packs 333 are fixedly connected with Elastic band 335, said elastic band 335 is fit on the frame 42 through the gap of spring 434, said clasp 332 is transition fit on the connecting rod 435 through guard claw 334, indirectly changes the contact area between the structures, said clamp 433 It includes a swing arm 321, a collar 322, a top file 323, a positioning structure 324, and a compass 325. The swing arm 321 is an arc-shaped structure, and the positioning s...

Abstract

The invention discloses a neurology brain marrow fluid extraction and inspection all-in-one device which structurally comprises a grip, a bottle cap, an extraction needle, a measuring cup and a tympanic membrane, the grip is connected with the extraction needle through the bottle cap, the bottle cap is connected to the measuring cup, the tympanic membrane is arranged in the measuring cup, the measuring cup comprises a cup bottom, a frame, an assisting body, a cotton filling chamber and a side buckle, the cup bottom is connected with the tympanic membrane through the side buckle and is connected to the frame . The frame is connected with the cotton filling chamber, the assisting body is installed in the cotton filling chamber, an exchange fork and a clamping support are installed on the assisting body, and the exchange fork and the clamping support are matched on a rotating shaft, so that when a hollow opening of the tympanic membrane is intensively stretched towards the interior of a needle head of the extraction needle in an arrow shape, the exchange fork is firstly folded and extruded; and the exchange fork is controlled by the rotating shaft to be drooped, positioned and supported on theclamping support, so that the exchange fork is extended on the spring, the X-shaped hollow structure of the tympanic membrane is converted into a swastika-shaped structure in cooperation with the exchange fork, the tympanic membrane is conveniently hung upside down at the extraction needle head, and the plugging effect of the tympanic membrane is enhanced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an integrated device for extracting and submitting cerebrospinal fluid in neurology. Background technique [0002] During the clinical treatment of neurology, it is often necessary to sample the cerebrospinal fluid and send it for inspection to find out the symptoms so as to carry out targeted treatment. The following disadvantages will occur: [0003] Generally, the extraction needle that has extracted the liquid is firmly sealed in a vacuum measuring cup for testing by using the tympanic membrane to form a double guarantee. Since the tympanic membrane has an "X"-shaped hollow structure, when the tympanic membrane passes through the difference between the internal and external vacuum, it moves upward in the measuring cup and approaches the extraction needle. When the needle is removed, it will change the radian of its own "X"-shaped hollow structure in a bulging shape, ...
