Description

Technical Field

[0001] The invention relates to the technical field of fish diagnosis, in particular to a fish blood drawing device. Background Art

[0002] Fish are the oldest vertebrates. They are the most numerous group within the phylum Chordata. They spend their entire lives in water, breathing with gills and using fins for locomotion and balance. Their only auditory organ is the inner ear, and most of their bodies are covered with scales. Their body temperature fluctuates with their environment, making them cold-blooded. Fish are divided into cartilaginous fish and bony fish. Cartilaginous fish have a vestigial notochord and possess vertebrae. Their internal skeleton is cartilaginous, covered with scutes, and have 5-7 pairs of gill slits. Bony fish have a more or less ossified internal skeleton, and their bodies are covered with hard scales, comb scales, or round scales, and possess gill covers. Bony fish are the most abundant group of living fish, numbering over 23,600 species.

[0003] Drawing blood from fish requires drawing blood from the tail fin, a laborious and time-consuming process due to the inability to visualize blood vessels and the fish's intense struggles. Traditionally, fish blood drawing methods involve wrapping the fish with a moist cloth, exposing the tail fin, and inserting a needle to probe for blood vessels. This procedure involves immobilizing the fish for extended periods, leading to hypoxia and even death. Sudden movement can also hinder accurate identification or halt blood drawing, resulting in poor blood quality.

[0004] It can be seen that the existing fish blood drawing method still has the problems of long-term immobilization of fish, causing fish hypoxia or even death, and sudden movement making it difficult to determine or stop blood drawing, resulting in poor blood quality. Summary of the Invention

[0005] The purpose of the present invention is to provide a fish blood drawing device, which solves the problems of long-term immobilization of fish causing fish hypoxia or even death, and sudden movement causing difficulty in determining or stopping blood drawing, resulting in poor blood quality.

[0028] Example

[0029] like Figure 1-5As shown, the present invention provides a fish blood-drawing device, comprising an operating platform 1, a fish inlet 9 is provided at one end of the operating platform 1, brackets 2 are provided at the edges of both sides of the operating platform 1, a flushing device 3, a fixing device 4 and a blood-drawing device 5 are fixed on the brackets, a fish collecting device 6 is provided inside the other end of the operating platform 1, and support rods 8 are provided at both ends of the bottom of the operating platform 1.

[0030] Baffles 7 are provided on both sides of the fish inlet 9 and the upper surface of the operating platform 1.

[0031] The flushing device 3 includes a flushing sleeve 31 located below the bracket and a water pump 34 located above the bracket. The flushing sleeve 31 and the water pump 34 are connected through a water supply pipe 33. A water outlet 32 ​​is provided at the bottom of the flushing sleeve 31, and one end of the water pump 34 is provided with a water inlet pipe 35 connected to the water source.

[0032] The fixing device 4 includes a fish head fixing rod 41 and a fish tail fixing rod 42. The bottoms of the fish head fixing rod 41 and the fish tail fixing rod 42 are respectively embedded with a fixed inner rod 1 47 and a fixed inner rod 2 48. The bottoms of the fixed inner rod 1 47 and the fixed inner rod 2 48 are both connected with a fixed clamp 45, and the fixed clamp 45 is covered with anti-slip cotton 46.

[0033] The outer surfaces of the fish head fixing rod 41 and the fish tail fixing rod 42 are both provided with limiting bolts 43, and the limiting bolts 43 are respectively connected to the limiting holes 44 provided on the fixed inner rod 1 47 and the fixed inner rod 2 48.

[0034] The blood drawing device 5 includes a blood drawing rod 51, the bottom of which is connected to a blood drawing needle 52. The blood drawing needle 52 is connected to a blood drawing pump 54 arranged at the top 51 of the blood drawing rod through a blood drawing blood tube 53 arranged inside the blood drawing rod 51. The other end of the blood drawing pump 54 is provided with an outlet blood tube 55, and the bottom of the outlet blood tube 55 is provided with a collecting tube 56.

[0035] The fish collecting device 6 includes an inner groove 61 opened inside the operating platform 1, and a fish collecting plate 62 is provided in the inner groove 61. One end of the fish collecting plate 62 is connected to a pull rod 65, and the pull rod 65 extends to the outside of the inner groove 61 and is connected to the pull plate handle 63. A fish collecting bucket 65 is provided below the fish collecting plate 62.

[0036] The fish inlet 9 is an inclined plate structure, which forms an acute angle with the horizontal plane.

[0037] Working Principle: The fish to be bled is lowered through the fish inlet 9 onto the operating platform 1. The stop bolts 43 are adjusted to position the fish head and tail fixing rods 41 and 42 on the fixing device 4 to the desired height. The fixing jaws 45 are adjusted to secure the fish. The fixing jaws 45 are movable, allowing for adjustment of the distance between the two jaws. Water, connected by a water pump 34, is then transferred to the water outlet 32, supplying water to the fish's head. The blood drawing rod 51 and flushing rod 31 share the same structure as the fish head and tail fixing rods 41 and 42: they are telescopic rods and feature stoppers. The blood drawing rod 51 is adjusted to allow the blood drawing needle 52 to penetrate the fish's tail fin. The blood drawing pump 53 then draws a fixed amount of blood, which is then collected in the collection tube 56. After blood drawing is complete, the lever handle 63 is pulled, causing the lever 65 to drive the fish collecting plate 62 into the inner tank. The fish then escapes the operating platform 1 and falls into the fish collecting bucket 64.

[0038] Therefore, the present invention utilizes the aforementioned fish blood-drawing device, which features a simple structure and is easy to operate. It is equipped with a fixing device that secures the fish's head and tail, effectively preventing sudden movement of the fish during blood-drawing. Furthermore, the fixing jaws are equipped with anti-slip cotton to prevent the fish from struggling and breaking free from the fixing device, providing excellent stability. The water outlet continuously provides water to the fish's head, supplying oxygen to the gills, preventing prolonged immobilization of the fish from causing hypoxia or death. Furthermore, the time the fish is out of water is reduced.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
