Description

Technical Field

[0001] This invention relates to the field of egg white sampling technology, and in particular to an egg white sample sampling device. Background Technology

[0002] Avian leukosis (AL) is a neoplastic disease caused by the avian leukosis virus (ALV), primarily affecting poultry, especially chickens. This disease not only leads to immunosuppression in chickens but also significantly reduces their production performance, including egg production and feed conversion ratio, resulting in substantial economic losses for the poultry industry.

[0003] In the prevention and control of avian leukosis, egg white ELISA kits have high sensitivity and specificity, making them suitable for screening large flocks. They are widely used to monitor the virus carriage status of hens. Studies have shown that hens infected with avian leukosis exhibit viral replication in their reproductive system, particularly in the protein secretion region of the oviduct, thus their eggs often carry the virus. By detecting viral antigens in egg white, the infection status of the flock can be effectively assessed, and corresponding prevention and control measures can be taken. However, currently, egg white sampling relies on manual labor, which is time-consuming and labor-intensive. Furthermore, due to operator inexperience, the interval between sample additions on the same plate can be too long, affecting the accurate interpretation of ELISA results.

[0004] Utility model patent application CN201720621542.X discloses an egg white and yolk separator, including an egg yolk container, an egg white container, an egg-beating device, and a support leg. The egg yolk container, egg white container, and support leg are arranged sequentially from left to right on the same horizontal plane. A support frame is fixedly connected to the top of the support leg, and a first conveying chute for use with the egg yolk container is fixedly connected to the top of the support frame. A fixing hole for use with the support frame is opened on the right side of the surface of the first conveying chute. This utility model, by setting up the combined use of the first and second conveying chutes, can quickly separate egg yolks and egg whites. This improves the separation efficiency of egg yolks and egg whites, solving the problem that manual separation of egg yolks and egg whites requires a lot of manpower, resulting in a low separation speed. It greatly improves the separation efficiency of egg yolks and egg whites, saves a lot of manpower, and is suitable for widespread use.

[0005] While the aforementioned technologies can effectively separate egg whites and yolks, due to different application methods, a separate sampling process is required for the egg whites to be tested in order to prevent sample contamination. Therefore, after the egg whites of one egg are sampled, the sampler needs to be cleaned before the next egg can be cleaned. Thus, a technology is needed that can clean the sampler after a single egg white sampling. Summary of the Invention

[0006] This invention provides an egg white sample collection device that can solve the problem of sample contamination when sampling multiple eggs.

[0007] To solve the above-mentioned technical problems, this application provides the following technical solution: an egg white sample collection device, comprising:

[0008] Sampling chamber; the bottom of the sampling chamber is provided with a sampling needle for piercing the eggshell and extracting the egg white;

[0009] Push block: The push block is slidably connected within the sampling chamber;

[0010] Reciprocating device: used to push the pusher block to slide within the sampling chamber;

[0011] Washing solution tank: Located outside the sampling chamber, containing washing solution; connected to the sampling chamber by an infusion tube;

[0012] When the pusher is at the upper limit position of the sampling chamber, the washing liquid tank and the sampling chamber are connected; during sampling, the height of the pusher is lower than the upper limit position.

[0013] The basic principle and beneficial effects of this scheme are as follows: The reciprocating mechanism first moves to the lower stop position to purge the air from the sampling chamber. Then, the sampling device is moved close to the egg, and the sampling needle is used to pierce the eggshell and insert into the egg white. The reciprocating mechanism then moves the push block upward, generating suction in the sampling chamber to sample the egg white. After obtaining the required amount of sample (at this time, the push block has not reached the upper stop position), the egg white sample is transferred to the top of the sampling box. The reciprocating mechanism pushes the push block downward to discharge the egg white into the sampling box. Then, the sampling device is moved away from the sampling box, and the push block is moved to the upper stop position simultaneously, so that the washing liquid tank is connected to the sampling chamber. The washing liquid flows into the sampling chamber. After a certain time or a certain amount has been discharged, the reciprocating mechanism moves down to the lower stop position again to drain all the washing liquid in the sampling chamber and prepare for the next sampling.

[0014] This solution implements a sampling device cleaning process before each sampling to prevent the sample from being contaminated or mixed.

[0015] Furthermore, it also includes a frame: an operating plane is provided on the top of the frame; a first track is fixed on the operating plane, the first track extends along the front-back direction of the operating plane, a first slider is slidably connected to the first track, a second track is fixed on the top of the first slider, the second track extends along the left-right direction of the operating plane, a second slider is slidably connected to the second track, a third track is fixedly connected to the second slider, the third track stands vertically on the top of the operating plane, a third slider is slidably connected to the third track; the fixed ends of the sampling chamber, washing liquid tank and reciprocating device are all fixed on the third slider.

[0016] Beneficial effects: Mechanized operation is achieved by setting up an egg placement area, a sample area, and a cleaning area on the operating plane. Through the cooperation of three tracks and three sliders, the sampling device can move freely in the space above the operating plane. That is, it takes a sample in the placement area, then transfers it to the sample area to discharge the sample, and finally discharges the washing liquid in the cleaning area. Then it returns to the placement area for the next sampling. By repeating the operation, mechanized automatic sampling can be completed.

[0017] Furthermore, the reciprocating device is a telescopic rod or a cylinder.

[0018] Furthermore, the reciprocating device is a telescopic rod, the free end of which is fixedly connected to the top of the push block, and the telescopic base of the telescopic rod is located outside the sampling chamber, and the telescopic base is fixedly connected to the third slider.

[0019] Furthermore, the first slider, the second slider, and the third slider are all driven by ball screws.

[0020] Furthermore, multiple sampling devices are arranged side by side.

[0021] Furthermore, the infusion tubes are multiple, and each infusion tube is individually connected to each sampling chamber.

[0022] Furthermore, the bottom of the washing liquid tank is at a height higher than the height of the connection point between the infusion tube and the infusion chamber.

[0023] Beneficial effect: It facilitates the faster flow of washing solution into the sampling chamber under the action of gravity. Attached Figure Description

[0032] An egg white sample collection device, characterized in that it comprises:

[0033] Sampling chamber 62; the bottom of the sampling chamber 62 is provided with a sampling needle 61 for piercing the eggshell and extracting the egg white;

[0034] Push block 66: The push block 66 is slidably connected within the sampling chamber 62;

[0035] Reciprocating device: used to push the pusher 66 to slide within the sampling chamber 62; the reciprocating device is a telescopic rod 63 or a cylinder. In this solution, the reciprocating device is a telescopic rod 63, and an electric telescopic rod 63 is selected, that is, it can achieve a fixed size of extension and retraction under electric control as required. This solution makes an adaptive selection based on actual needs.

[0036] Washing liquid tank 64: Located outside the sampling chamber 62, containing washing liquid; connected to the sampling chamber 62 by an infusion tube 65; the bottom of the washing liquid tank 64 is higher than the height of the connection between the infusion tube 65 and the infusion chamber.

[0037] When the pusher block 66 is at its upper limit position in the sampling chamber 62, the washing liquid tank and the sampling chamber 62 are connected; during sampling, the height of the pusher block 66 is below its upper limit position. (See attached diagram) Figure 5 As shown, when pusher 66 is at the top dead center position, infusion tube 65 connects sampling chamber 62 and washing solution tank 64. ELISA washing solution is used in this procedure.

[0038] As attached Figure 1-3 As shown, it also includes a frame 1: the top of the frame 1 is provided with an operating plane; a first track 2 is fixed on the operating plane, the first track 2 extends along the front-back direction of the operating plane, a first slider 51 is slidably connected to the first track 2, a second track 3 is fixed on the top of the first slider 51, the second track 3 extends along the left-right direction of the operating plane, a second slider 52 is slidably connected to the second track 3, a third track 4 is fixedly connected to the second slider 52, the third track 4 stands vertically on the top of the operating plane, a third slider is slidably connected to the third track 4; the sampling chamber 62, the washing liquid tank 64 and the fixed end of the reciprocating device are all fixed on the third slider.

[0039] The first slider 51, the second slider 52, and the third slider are all driven by ball screws. The free end of the telescopic rod 63 is fixedly connected to the top of the push block 66, and the telescopic base 67 of the telescopic rod 63 is located outside the sampling chamber 62, and the telescopic base 67 is fixedly connected to the third slider. That is, this solution adopts the existing three-axis structure (corresponding to the first track 2, the second track 3, and the third track 4) to complete the movement of the sampler 6 in space. By sliding the first slider 51, the second slider 52, and the third slider, the forward, backward, left, right, and up and down movement of the sampler 6 can be indirectly or directly controlled. Based on this, the telescopic rod 63 controls the sliding of the push block 66 in the sampling chamber 62 to complete the sampling. That is, by manipulating the first slider 51 and the second slider 52 to move above the egg, and then manipulating the third slider to move down until it pierces the eggshell, the telescopic rod 63 moves up, driving the push block 66 to move up, and the egg white is drawn into the sampling chamber 62 for sampling.

[0040] Multiple sampling devices are arranged side by side. There are multiple infusion tubes 65, and each infusion tube 65 is individually connected to each sampling chamber 62.
