Description

Technical Field

[0001] This utility model relates to the field of anesthesia injector technology, specifically a novel anesthesia injector. Background Technology

[0002] As is well known, anesthesia injectors are a common injection device used to inject drugs into the human or animal body. They have a wide range of applications, and in some animal farms, anesthesia injectors are often provided to prevent animals from getting sick.

[0003] Chinese utility model publication CN216495832U discloses a multifunctional anesthesia injector, including a syringe, an end cap, and a needle. One end of the syringe is connected to the needle via a connector. A protective sleeve is fitted onto the outside of the needle. A PP limiting plug is bonded to the inside of the protective sleeve with polyurethane adhesive. Handles are welded to the top and bottom of the syringe. A piston is disposed inside the syringe. A piston rod is mounted on one end of the piston through a mounting hole. An infusion channel is disposed inside the piston rod. An end cap is heat-fused to one end of the piston rod. A limiting groove is disposed on one side of the end cap, and an LED bead is mounted in the limiting groove via a mounting base. A button battery is mounted on one end of the LED bead via a screw.

[0004] While the device achieves the effect of continuous drug addition, the needle of the anesthetic syringe is exposed both when adding new drugs and when it is removed from the animal's body. Due to the darkness, when the staff moves the anesthetic syringe, the needle is prone to come into contact with foreign objects, which can damage the needle, or scratch the skin and cause wounds. Therefore, the safety is not very good and there is room for improvement. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a novel anesthesia injector that improves safety.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a novel anesthesia injector, comprising an injector body and a needle, wherein a connecting rod is provided at the lower part of the injector body, a sliding groove is provided inside the connecting rod, and a blocking tube is slidably connected thereto for blocking the needle, a through hole is provided in the middle of the connecting rod and passes through the sliding groove, the needle passes through the through hole, and a driving device is provided at one end of the connecting rod for pushing the blocking tube to move.

[0009] Furthermore, the driving device includes several springs, one end of each spring is connected to the side wall of the groove of the connecting rod, and the other end of each spring is provided with a push plate for pushing the blocking tube to move.

[0010] Furthermore, the side wall of the groove opening of the slide is provided with an internal thread, and the outer wall of the pipe opening of the shielding tube near the push plate is provided with an external thread, which is threaded together with the internal thread of the slide to fix the two together.

[0011] Furthermore, the corner of the shielding tube away from the connecting rod is rounded to avoid scratching the skin.

[0012] Preferably, both the shielding tube and the connecting rod are made of transparent material.

[0013] Preferably, the syringe body has an injection port on its side wall and is equipped with a drug inlet tube for adding drugs. The drug inlet tube is equipped with a valve for opening.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a novel anesthesia injector, which has the following beneficial effects:

[0016] This new type of anesthesia injector allows for the addition of new drugs or the injection of anesthetics into other animals. By rotating the shielding tube, the shielding tube and the connecting rod are threaded together. At this time, the shielding tube covers the needle and will not slide into the groove of the connecting rod under the impact of external force. Therefore, it ensures that the needle will not come into contact with foreign objects, which could damage the needle or scratch the skin, thus improving safety. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model discloses a novel anesthesia injector, comprising an injector body 1 and a needle 2. A connecting rod 3 is provided at the lower part of the injector body 1. A groove 4 is provided inside the connecting rod 3, and a blocking tube 5 is slidably connected thereto. The blocking tube 5 slides out a certain distance within the connecting rod 3 to block the needle 2. A through hole 6 is provided in the middle of the connecting rod 3, and passes through the groove 4. The needle 2 passes through the through hole 6 to facilitate injection into the animal. A driving device is provided at one end of the connecting rod 3 to push the blocking tube 5 to slide within the connecting rod 3 to block the needle 2.

[0026] The driving device includes several springs 7. One end of each spring 7 is connected to the side wall of the slide groove 4 of the connecting rod 3. The other end of each spring 7 is provided with a push plate 8. The springs 7 provide a reaction force to the push plate 8, causing the push plate 8 to push the blocking tube 5 to move.

[0027] The side wall of the groove 4 is provided with an internal thread 9, and the outer wall of the tube opening of the shielding tube 5 near the push plate 8 is provided with an external thread 10, which is threaded together with the internal thread 9 of the groove 4. The external thread 10 of the shielding tube 5 is threaded to the internal thread 9 of the groove 4, and the two are fixed together. At this time, when the syringe body 1 is moved or new drugs are added, the shielding tube 5 will not be squeezed into the groove 4 of the connecting rod 3 when it comes into contact with foreign objects.

[0028] The corner of the shielding tube 5 away from the connecting rod 3 is rounded to prevent the corner of the shielding tube 5 from scratching the animal's skin when medical personnel inject anesthesia, thus increasing the animal's fear.

[0029] Both the shielding tube 5 and the connecting rod 3 are made of transparent material, making it easy to see the needle 2 inside through the shielding tube 5.

[0030] The syringe body 1 has an injection port on its side wall and is equipped with a drug inlet tube 11. The drug inlet tube 11 is equipped with a valve. When the valve is opened, new drugs can be added into the syringe body 1 through the drug inlet tube 11.

[0031] In summary, when using this novel anesthesia injector, the user opens the valve on the inlet tube to inject the liquid into the injector body 1 through the inlet tube, closes the valve, grasps the injector body 1, and then inserts the needle 2 into the injection site. When the blocking tube 5 contacts the animal's skin, it is pressed into the groove 4 of the connecting rod 3, simultaneously pushing the push plate 8 to move and compressing the spring 7. After the injection is completed, the needle 2 is pulled out. When new drugs need to be added, the blocking tube 5 is rotated so that the external thread 10 of the blocking tube 5 and the internal thread 9 of the connecting rod 3 are connected together and fixed together. Then, the drugs can be added through the inlet tube.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
