Problems solved by technology

[0006] The present invention solves the defects that the existing lung tissue fixation speed is slow, affects the immersion efficiency of the fixative, causes the exposure time of the lung tissue to be too long, and affects the experimental results, and provides a multi-chamber lung tissue fixation instrument, which is provided with a The pumping channel reduces the pressure in the placement chamber through the pumping channel, accelerates the discharge of air inside the lung tissue, and also accelerates the immersion of the fixative, shortens the exposure time of the lung tissue, and ensures the correctness of the experimental results
[0007] The present invention also solves the defects that the existing lung tissue is severely shrunk when the lung tissue is fixed, which easily destroys the normal structure of the lung tissue and affects the experimental results. It provides a multi-chamber lung tissue fixation instrument. The channel speeds up the discharge of air inside the lung tissue and the immersion of the fixative without destroying the normal structure of the lung tissue, ensuring correct experimental results

Embodiment 1

[0024] Embodiment 1: A kind of lung tissue multi-chamber fixation instrument (see figure 1 ), including a transparent fixed body 1, inside the fixed body is provided with a housing chamber 12, on the side of the fixed body is provided with an air pumping channel 2 connected to the housing chamber, in the air pumping channel is provided with an air core, and in the housing chamber is provided with A plurality of placement cavities 13, a plurality of openings 11 corresponding to the placement cavities are provided on the top of the fixed body, and a sealing cover 10 is provided at each opening. A number of positioning parts 5 are arranged outside the air suction channel of the fixed body, and a number of fixing parts 6 that cooperate with the positioning parts are arranged on the air core, and the fixing parts cooperate with the corresponding positioning parts to limit the extraction length of the air core.

[0025] The placement cavity in the accommodation cavity is sunken into...

Embodiment 2

[0028] Embodiment 2: A kind of lung tissue multi-chamber fixation instrument (see figure 2 ), the difference from Embodiment 1 is that a lung tissue placement channel 15 is provided between the placement cavity and the opening, an air extraction hole 16 is opened on the side wall of the lung tissue placement channel, and the upper end of the placement channel is connected to the opening on the top of the accommodation cavity. Docking. Refer to Example 1 for all the other structures.

[0029] When the lung tissue is placed, the lung tissue falls along the placement channel to ensure that the lung tissue can accurately fall into the corresponding placement cavity, which is convenient for placement.

Embodiment 3

[0030] Embodiment 3: A kind of lung tissue multi-chamber fixation instrument (see image 3 ), and the difference from Embodiment 1 is that: a holding device 17 for holding a fixative is placed in the chamber, the holding device is a test tube structure, the upper end of the holding device extends to the opening, and the inside of the holding device communicates with the containing chamber. The caliber of the opening at the top of the fixed body is greater than the upper outer diameter of the containing device, the containing device and the opening are clearance fits, and the containing device is provided with a suction hole 16 on the side wall above the liquid level of the stationary liquid. Refer to Example 1 for all the other structures.

[0031] The containing device can be separated from the fixed body, that is, the lung tissue is directly put into the containing device outside the body at the fixed point, and then the containing device is directly put into the containing ...

Abstract

The invention relates to a multi-cavity fixation instrument for lung tissue. The multi-cavity fixation instrument for lung tissue comprises a fixation body. A containing cavity is formed in the fixation body. An air suction channel communicated with the containing cavity is formed in the side face of the fixation body, and an air suction core is arranged in the air suction channel. A plurality of storage cavities are formed in the containing cavity, a plurality of openings in one-to-one correspondence with the storage cavities are formed in the top of the fixation body, and each opening is provided with a sealing cover. Due to the fact that the storage cavities are formed, and each storage cavity corresponds to one opening, the inner space of the fixation instrument is reasonably and effectively utilized, lung tissue can be taken out or placed in from the openings, lung tissue in each storage cavity can be conveniently recognized, and confusion is avoided.

Description

technical field [0001] The invention relates to a tissue fixation device, in particular to a lung tissue multi-chamber fixation instrument. Background technique [0002] When making pathological sections of animal lung tissue, it is necessary to fix the lung tissue. When observing the lung tissue staining, we not only need to observe clear stained tissue, but also need to keep the shape of the lung tissue intact to avoid tissue damage and alveolar collapse. . [0003] Currently, there are three main lung tissue fixation methods: 1. Using embedding cassettes, the lung tissue is fixed in formaldehyde solution. 2. Put a small ball of cotton on the surface of the formaldehyde solution put into the lung tissue to infiltrate the lung tissue. 3. Use an infusion tube to inject a small amount of formaldehyde solution into the lungs through the trachea. [0004] Although method 1 can quickly infiltrate the lung tissue into the formaldehyde solution, it will cause serious lung colla...
