Description

Technical Field

[0001] This utility model relates to the field of veterinary instrument technology, and in particular to a nanocapsule feeding device. Background Technology

[0002] Nanocapsules are core-shell structures with a scale ranging from 1 to 100 nanometers, exhibiting significant variations in their physicochemical properties. The outer shell can be made of materials such as graphite and polymers, while the core can encapsulate metals, drugs, or compounds. They are prepared using techniques such as complex condensation and microemulsion polymerization, providing protection for the core and controlled release. To ensure safe and successful administration to animals, a capsule feeder is used to deliver the nanocapsule deep into the back of the tongue, ensuring the drug is swallowed intact and does not become lodged in the throat or vomited out.

[0003] Existing capsule feeders are only suitable for standard-sized capsules, and are not stable when used with extra-large or extra-small capsules, thus having limited applicability. Utility Model Content

[0004] The purpose of this invention is to provide a nanocapsule feeder that can be replaced according to the size of the capsule, thereby improving the applicability of the capsule feeder.

[0005] To achieve the above objectives, a nanocapsule feeder is provided, comprising a feeding cylinder, one end of which has a pushing mechanism that extends through the feeding cylinder. An mounting head is fixedly connected to the end of the feeding cylinder away from the pushing mechanism. The mounting head, a retaining ring, and the feeding cylinder are integrally injection molded. A clamping mechanism is provided on the side of the mounting head away from the feeding cylinder, and the clamping mechanism is inserted into the mounting head. This allows for replacement according to the size of the capsule, improving the applicability of the capsule feeder.

[0006] According to the aforementioned nanocapsule feeder, the clamping mechanism comprises an insertion sleeve and grippers. Multiple grippers are equidistantly fixed to one end of the insertion sleeve, and the grippers are elastic. The end of the insertion sleeve furthest from the grippers is inserted into an installation head. The grippers utilize their elasticity to hold the capsule placed between them.

[0007] According to the aforementioned nanocapsule feeder, the pushing mechanism comprises a retaining ring, a guide plate, and a push rod. The push rod passes through the feeding cylinder. The retaining ring is fixedly connected to the end of the push rod away from the clamping mechanism. Multiple guide plates are provided and equidistantly fixedly connected to the surface of the push rod, with the outer end of the guide plate slidably connected to the inner wall of the feeding cylinder. One end of the guide plate is fixedly connected to the retaining ring. The retaining ring limits the user's thumb, facilitating user control of the push rod's movement, while the guide plate ensures the stability of the push rod's movement within the feeding cylinder.

[0008] According to the aforementioned nanocapsule feeder, the feeding cylinder has a large opening and a small opening at both ends, respectively. The pushing mechanism is located on the side with the large opening of the feeding cylinder, and one end of the pushing mechanism extends out from the small opening of the feeding cylinder. This design restricts the pushing mechanism, preventing it from passing completely through the feeding cylinder and making it easier for the user to distinguish between the front and back.

[0009] According to the aforementioned nanocapsule feeder, a flexible clamping block is fixedly connected to the side of the gripper facing the inner wall of the insertion sleeve, and the flexible clamping block is located at the end of the gripper away from the insertion sleeve. The flexible clamping block prevents damage to the capsule when the gripper clamps it.

[0010] According to the aforementioned nanocapsule feeder, the outer side of the insertion sleeve is equidistantly fitted with several rubber anti-slip rings, and the anti-slip rings are interference-fitted with the inner wall of the mounting head. The anti-slip rings prevent the clamping mechanism from being pulled off the feeder when the capsule is pushed out by the pushing mechanism.

[0011] According to the aforementioned nanocapsule feeder, two fixing rings are symmetrically fixed to the outer end of the feeding cylinder, and the fixing rings and the pushing mechanism are located at the same end of the feeding cylinder. The fixing rings facilitate the user to hold the feeding cylinder in place and move the pushing mechanism.

[0012] According to the aforementioned nanocapsule feeder, the flexible clamping block is a silicone block with a surface coated with polytetrafluoroethylene. Reducing the surface roughness of the flexible clamping block decreases the resistance encountered by the pushing mechanism when pushing the capsule away from the clamping mechanism.

[0013] The above-mentioned solution has the following beneficial effects: The capsule is secured by a clamping mechanism, which, together with the pushing mechanism, delivers the capsule deep into the base of the animal's tongue. The clamping mechanism can be replaced according to the size of the capsule, improving the applicability of the capsule feeder.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-4 This utility model provides a nanocapsule feeding device, which includes a feeding cylinder 2. The large opening end of the feeding cylinder 2 is provided with a pushing mechanism 1, and one end of the pushing mechanism 1 enters the feeding cylinder 2 from the large opening and extends out from the small opening of the feeding cylinder 2. The small opening end of the feeding cylinder 2 is fixedly connected to an installation head 8. The side of the installation head 8 away from the feeding cylinder 2 is provided with a clamping mechanism 3, and the clamping mechanism 3 is inserted into the installation head 8.

[0019] The clamping mechanism 3 consists of an insertion sleeve 9 and grippers 11. The insertion sleeve 9 and grippers 11 are made of plastic and are integrally injection molded. Multiple grippers 11 are provided and are fixedly connected to one end of the insertion sleeve 9 at equal intervals. The grippers 11 are elastic. The end of the insertion sleeve 9 away from the grippers 11 is inserted into the mounting head 8. The grippers 11 use their elasticity to clamp the capsule placed between them.

[0020] The medication delivery mechanism 1 consists of a retaining ring 5, a guide plate 6, and a push rod 7. The retaining ring 5, guide plate 6, and push rod 7 are integrally molded using injection molding. The push rod 7 passes through the medication delivery cylinder 2. The retaining ring 5 is fixedly connected to the end of the push rod 7 away from the clamping mechanism 3. Multiple guide plates 6 are provided and equidistantly fixed to the surface of the push rod 7, with the outer end of the guide plate 6 slidably connected to the inner wall of the medication delivery cylinder 2. One end of the guide plate 6 is fixedly connected to the retaining ring 5. The retaining ring 5 limits the user's thumb, facilitating user control of the push rod 7's movement. The guide plate 6 ensures the stability of the push rod 7's movement within the medication delivery cylinder 2.

[0021] The feeding cylinder 2 has a large opening and a small opening at each end. The pushing mechanism 1 is located on the side with the large opening of the feeding cylinder 2, and one end of the pushing mechanism 1 extends out from the small opening of the feeding cylinder 2. This can restrict the pushing mechanism, prevent the pushing mechanism 1 from passing completely through the feeding cylinder 2, and make it easier for the user to distinguish between the positive and negative sides.

The mounting head 8, the fixing rings 4 and the feeding cylinder 2 are integrally injection molded. The fixing rings 4 make it easy for the user to fix the feeding cylinder 2 and move the pushing mechanism 1.

[0025] The flexible clamping block 10 is a silicone block with a polytetrafluoroethylene coating. Reducing the surface roughness of the flexible clamping block reduces the resistance encountered by the drug pushing mechanism 1 when pushing the capsule away from the clamping mechanism 3.

[0026] Working principle: When using, select the appropriate clamping mechanism 3 according to the size of the nanocapsule to be fed, and insert the insertion sleeve 9 of the clamping mechanism 3 into the installation head 8. Then, insert one end of the nanocapsule between the claws 11. Use the elasticity to make the flexible clamping block 10 on the claws 11 clamp the capsule. Then, like the use of a medical syringe, hold the feeding tube 2 and insert it into the mouth to the root of the animal's tongue. Then, push the locking ring 5 with your thumb to push the push rod 7 to push the capsule and send the nanocapsule deep into the root of the tongue.
