[0002] In modern times, electronic chips have been able to be applied to animals. People implant electronic chips under the skin of animals to obtain relevant information of the animals, which facilitates people's management of animals.

[0003] Currently, injecting an electronic chip with a syringe is one of the most commonly used means of implanting an electronic chip. However, due to the relatively small volume of the electronic chip, the electronic chip is often hidden in the syringe needle tube for packaging after the syringe is produced. Therefore, even if the electronic chip is lost during transportation, it is not easy to detect in the subsequent use process, and there may be mistakes in the subsequent process of implanting the electronic chip into animals.

[0004] In the prior art, the patent application number CN201921979515.5 discloses an electronic chip syringe, which includes a barrel, a needle seat, and a push rod passing through the barrel and the needle seat. A needle tube is fixed on the needle seat, an injection port is formed on the needle tube, and an electronic chip exposed at the outer end of the injection port is installed in the needle tube. The push rod includes an injection rod passing through the syringe barrel and capable of moving back and forth in the needle tube, and an elastic member is connected to the injection rod, and the elastic member makes the electronic chip have a tendency to move forward. The electronic chip is exposed at the injection port of the syringe, and the user can judge whether the electronic chip is lost by observing the injection port, and it does not affect the normal use of the syringe.

[0005] However, the existing biomarker chip syringes have the following disadvantages:

[0006] Each syringe can only inject one biomarker chip at a time. Since the number of biomarker chips for marking fish is huge, two people need to closely cooperate during injection. One person loads the chip and the other person injects the chip, resulting in waste of manpower and material resources.

[0007] Due to the manufacturing shape not conforming to the ergonomic structure, it is not convenient and simple to use; the above-mentioned technology can only load one chip at a time and does not have continuous injectability. Summary of the Utility Model

[0008] The purpose of the utility model is to provide a continuous injection device for a biomarker chip, which solves the problems of non-continuity, inconvenient operation and inconvenience during the injection of fish chips.

[0009] To solve the above technical problems, the utility model adopts the following technical solutions:

[0011] At one end of the needle close to the syringe outer shell, a chip magazine is arranged, a chip booster plate is limited in the chip magazine, a chip spring is arranged below the chip booster plate; a plurality of biomarker chips are carried on the top of the chip booster plate.

[0012] Further, two finger fixing rings are symmetrically arranged on the side wall of the syringe outer shell.

[0013] Still further, a reserved channel for facilitating the pushing of the chip push rod is arranged in the needle.

[0014] Still further, the upper port of the chip magazine is perpendicular and communicated with the needle.

[0015] Still further, a limiting block for preventing the chip spring from popping out is arranged on the inner wall of the upper part of the chip magazine; a loading port is arranged on the side wall of the chip magazine; a vertical opening is further arranged on the side wall of the chip magazine, and a retractable pressing handle extending out of the vertical opening is arranged on the chip booster plate.

[0016] Still further, a partition board is arranged in the syringe outer shell, a reserved hole for facilitating the passing of the chip push rod is arranged at the center of the partition board, and the chip push rod spring is located between the partition board and the main push rod.

[0017] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0018] In the utility model, through transformation and upgrading on the basis of the existing technology, the continuous operation of injecting the biomarker chip is realized, and the injection efficiency is improved; and the outer shell and the internal structure are further optimized, making it more efficient and convenient.

[0024] The syringe housing 6 is used to support the normal operation of the internal components; wherein the needle 1 punctures the injection site of the fish body, and the biomarker chip is injected to a predetermined position through the needle.

[0025] A chip magazine 3 is vertically installed on the needle 1 and near one end of the syringe housing 6. A chip booster plate 4 is installed in the chip magazine 3 in a limited manner, and a chip spring 2 is installed below the chip booster plate 4; a plurality of stacked biomarker chips are carried on the top of the chip booster plate 4;

[0026] For the main push rod 9, pressing the main push rod with the thumb can complete the chip injection action.

[0027] Two finger fixing rings 8 are symmetrically installed on the side wall of the syringe housing 6. During injection, the index finger and middle finger can be fixed in the fixing rings to ensure stability.

[0028] In this embodiment, a reserved channel for facilitating the pushing of the chip push rod 5 is opened in the needle 1. After the chip magazine 3 sends the chip to a fixed position, the chip can be pushed into the fish body through the chip push rod 5 with the needle 1 as the channel;

[0029] During use, the biomarker chip located above the chip magazine 3 is pushed into the reserved channel of the needle 1 through the chip push rod 5 until it enters the fish body; when the chip push rod 5 is located above the chip magazine 3, it can always block the upper port of the chip magazine 3 to prevent too many biomarker chips from being ejected.

[0030] In this embodiment, the upper port of the chip magazine 3 is perpendicular and connected to the needle 1, and can continuously send the biomarker chip to the channel opening of the needle 1; 40 biomarker chips can be loaded into the chip magazine 3 at one time; the bottom of the chip booster plate 4 is connected to the chip spring 2, and its top bears the biomarker chip, and the chip can be pushed into the predetermined position through this plate;

[0031] After the biomarker chips are loaded into the chip magazine 3, the chip spring 2 can continuously push the biomarker chips into the interior of the needle through the elastic force;

[0032] A limiting block 301 for preventing the chip spring 2 from popping out is installed on the upper inner wall of the chip magazine 3;

[0033] A loading port 302 is provided on the side wall of the chip magazine 3; a vertical opening is also provided on the side wall of the chip magazine 3. A resilient pressing handle 401 extending out of the vertical opening is connected to the chip booster plate 4; when loading the chips, the chip booster plate 4 is pressed down through the resilient pressing handle 401 so that it is located below the loading port 302, and then 40 chips are loaded above the chip booster plate 4 through the loading port 302.

[0034] In this embodiment, a partition is installed in the syringe housing 6, and a reserved hole for facilitating the passage of the chip push rod 5 is provided at the center of the partition. The chip push rod spring 7 is located between the partition and the main push rod 9 and is used to limit the chip push rod spring 7 to provide the reset ability for the chip push rod 5; when the chip injection is completed, the spring provides a reaction force to the chip push rod 5, enabling continuous and uninterrupted use.
