Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of auxiliary tool of radiography, concretely is an auxiliary radiography device. BACKGROUND

[0002] The detection of fish gill health status is an important aspect of fish growth research. Fish gill is the key organ of fish respiration, and its health status directly affects the survival and growth of fish. Fish gill absorbs dissolved oxygen in water and transports oxygen to fish blood, while expelling carbon dioxide outside the body. When the gill is damaged or diseased, its respiratory function will be affected, leading to hypoxia in fish body, and further affecting its growth and development. Therefore, detecting the health status of fish gill helps to discover fish diseases in time and take appropriate measures to ensure the stability of fish growth environment and the sustainable utilization of fish resources.

[0003] As shown in Figure 1 The current detection device involves placing the fish to be detected in a water tank containing an appropriate amount of anesthetic until the fish loses the ability to move, and then using an imaging device for imaging examination. After the examination is completed, the fish is transferred to a recovery tank containing clean water to promote its recovery. However, this method has obvious limitations: first, the device does not provide proper support to maintain the stable posture of the fish body, which may cause image blurring during imaging; second, the device does not support contrast detection, limiting in-depth observation of soft tissue conditions; and third, the gill of the fish is limited in its respiratory function under anesthesia, making it impossible to perform dynamic real-time imaging monitoring.

The auxiliary radiography device includes a mouthpiece, a contrast medium area, and a circulating water area, which can help fish maintain a suitable body position during detection, reduce stress, and recover normal activity more quickly after examination.

[0005] To achieve the above purpose, the utility model specifically adopts the following technical means:

[0006] An auxiliary radiography device includes a box body, a partition plate is arranged in the box body to divide the cavity into a closed area containing contrast medium and a circulating water area, a mouthpiece for fixing aquatic animals is installed on the partition plate, so that when the aquatic animals exchange gas, the contrast medium flows through the soft tissue to the circulating water area to complete imaging observation.

[0007] Further, the circulating water area side and rear are respectively provided with a water inlet and a water outlet to realize liquid circulation in the cavity.

[0008] Further, the partition plate is provided with a hole for mounting the mouth sleeve.

[0009] Further, the mouth sleeve is tightly combined with the mouth organ of the aquatic animal, so that the contrast medium in the closed area penetrates through the soft tissue of the aquatic animal to the circulating water area.

[0010] Further, the mouth sleeve is provided with an annular groove outside, and the mouth sleeve is embedded on the partition plate through the annular groove.

[0011] Further, the mouth sleeve is internally provided with a protrusion for clamping the mouth organ of the aquatic animal.

[0012] Further, the side wall of the mouth sleeve is uniformly provided with a plurality of fine holes, and a fishhook is further used to fix the mouth organ of the aquatic animal.

[0013] Further, the mouth sleeve is in the shape of a shallow cup, and gradually reduces from the cup opening to the cup bottom.

[0014] The present scheme has the following beneficial technical effects:

[0015] The cavity is divided into a closed area and a circulating water area by arranging the partition plate in the box body, and the mouth sleeve mounted on the partition plate can fix the aquatic animal and maintain the stable body position, so as to reduce the movement and blur in the imaging process and improve the image quality.

[0016] The auxiliary device is a non-invasive method, and the fish mouth is fixed by the silica gel mouth sleeve without anesthesia, so that the contrast medium naturally penetrates through the soft tissue of the fish, and the sensitive parts of the fish are not directly contacted, so as to reduce the interference and stress on the fish.

[0017] The annular groove outside the mouth sleeve can be embedded on the partition plate, and the mouth organ of the aquatic animal is fixed through the protrusion and the fishhook, so as to ensure the stability of the mouth sleeve and the safety of the animal. The shallow cup-shaped design of the mouth sleeve gradually reduces from the cup opening to the cup bottom, which is more suitable for the natural form of the fish mouth, and reduces the discomfort of the animal in the detection process.

[0029] Please refer to Figures 2-3 , auxiliary imaging device includes water tank 1 and mouthpiece 2, water tank 1 adopts acrylic material, and the mouthpiece 2 is made of silica gel material. The acrylic water tank is a transparent cubic recess structure for storing fish, and the top surface is missing. This material will not block the penetration of the rays. The water tank 1 has a partition 2, which divides it into two parts. The smaller closed area 101 on the left side is placed with the developing agent, and the larger circulating water area 102 on the right side is placed with flowing water and fish body.

[0030] The circulating water area 102 has a large space, and a circulating water system can be arranged. The water inlet 103 is arranged on both sides near the partition 2, and the water outlet 104 is arranged away from the partition 2. The circulating water area 102 is mainly used for storing the body of the fish to be detected. In addition, the partition 2 has a circular hole 201, and the mouth sleeve 3 can be placed in the hole.

[0031] The mouth sleeve 3 can fix the mouth of the fish to be detected, and is embedded in the partition 2 of the water tank. The mouth sleeve 3 is shaped like a volcano, and the base part faces the larger space of the water tank, and the crater part is the space for holding the contrast agent. In the non-working state, i.e. without fish, the two sides are communicated with each other, and in the working state, the contrast agent can only enter the other cavity through the gills of the fish.

[0032] Please refer to Figure 4 Two water inlets 103 are arranged on both sides of the circulating water area 102 near the partition 2, and a water outlet 104 is arranged away from the partition. The active water flows from the water inlet 103 to the water outlet 104, which ensures that the contrast agent permeating from the gills of the fish into the circulating water area 102 is discharged in time in the working state, so as to prevent the imaging from being affected.

[0033] Please refer to Figures 5-7 The mouth sleeve 3 is installed on the middle partition 2, and is used for fixing the mouth of the fish to be detected and preventing the liquid in the two cavities from penetrating each other. The mouth sleeve 3 is a shallow cup as a whole, and the cup opening has an annular groove 301 embedded in the hole 201 in the partition 2 of the acrylic water tank. The cup opening gradually decreases to the cup bottom, and the inside has a protrusion 303 capable of clamping the mouth of the fish. The cup bottom is provided with an opening, through which the contrast agent enters the fish mouth and is circulated to the circulating water area 102 through the gills. In addition, the protrusion 303 and the shallow cup side wall have six evenly distributed fine holes 302, and the fish hook 4 passes through the fine holes 302, which can further fix the fish mouth. The mouth sleeve 3 closely fits the fish mouth, so that the contrast agent in the closed area 101 can only penetrate from the gills to the circulating water area 102, and cannot leak from the gap between the fish mouth and the silicone sleeve.

[0034] Please refer to Figure 8 After starting the circulating water system, the fish to be detected is placed in the circulating water area 102, the fish mouth is placed in the fish mouth sleeve 3 to fix the fish in a proper body position, and the contrast agent is added in the closed area 101. With the breathing of the fish, the contrast agent flows to the circulating water area 102 through the gills, and the flow of the circulating water ensures that the contrast agent does not gather near the partition, so as to keep the gill contrast effect clear, and finally realize the real-time imaging observation of the gills.
