Abstract
Description
Technical Field
[0001] The utility model relates to a drug dispenser, in particular to an animal capsule or tablet drug dispenser. Background Art
[0002] In animal experiments and pet treatment, the administration of capsules and tablets is an essential operation, and the quality of the capsule and tablet administration operation is crucial. However, existing drug delivery devices have some limitations, mainly including the following aspects:
[0003] First, the loading part of the existing drug delivery device is an open cylinder slightly smaller than the outer diameter of the capsule. The open design makes it easy for the water-soluble capsule shell to come into contact with the liquid in the animal's mouth, esophagus or stomach during the drug delivery process, causing the capsule shell to dissolve prematurely, affecting the effectiveness of the capsule or tablet. In addition, when using, the capsule needs to be inserted into the open cylinder and squeezed by the slight deformation of the capsule shell. Due to the slight error in the particle size of the capsule shell, multiple attempts are usually required in the process of jamming the capsule, affecting work efficiency.
[0004] Second, the push rod surface of the existing drug delivery device is smooth and the drug delivery device has no fixing or braking device, which poses a risk of the push rod automatically sliding and accidentally ejecting the capsule. In addition, the push rod is likely to extend beyond the drug delivery tube during drug delivery, causing the push rod to contact the animal's body and easily scratch the animal's esophagus or stomach.
[0005] Third, the existing drug dispensers are made of metal. The hardness of metal increases the probability of damaging the animal's stomach or esophagus. Metal drug dispensers are sturdy and durable, but expensive. They are often cleaned and reused repeatedly, posing a risk of cross-contamination.
[0006] Fourth, the height of the medicine-filled cylinder of the existing drug dispenser can only accommodate one capsule. If multiple capsules are needed, the animal must be given the drug repeatedly, which can easily cause damage to the animal's esophagus or stomach. In addition, the existing drug dispenser is only suitable for capsule administration and cannot be used for tablet administration, and has a single function.
[0007] Therefore, it is necessary to improve the drug delivery device. Utility Model Content
[0008] In order to solve at least one of the above technical problems, the utility model provides an animal capsule or tablet dispenser.
[0009] An animal capsule or tablet dispenser includes a dosing barrel and a push rod. The dosing barrel and the push rod are of separate design. The bottom of the dosing barrel is a silicone layer. A "cross" opening is provided in the center of the silicone layer. The "cross" opening is in a closed state when not under force and in an open state when under force. The push rod is inserted into the dosing barrel through the top of the dosing barrel. A brake plate inclined toward the top of the dosing barrel is provided on the inner side of the dosing barrel. A plurality of indentations are provided on the surface of the push rod to cooperate with the brake plate so that the brake plate presses against the indentations, thereby preventing the push rod from automatically sliding to the bottom of the dosing barrel.
[0010] In some embodiments, a rubber layer is provided at the bottom end of the push rod, the diameter of the rubber layer is equal to the diameter of the inner wall of the barrel of the dosing barrel, and the shape of the rubber layer is the same as that of the silicone layer.
[0011] In some embodiments, the dimples are evenly distributed on the surface of the push rod; the number of the brake pads is even and they are symmetrically arranged on the inner side of the top of the drug delivery cartridge.
[0012] In some embodiments, the angle α between the brake plate and the cross section of the drug delivery cartridge is in the range of 15°≤α≤45°.
[0013] In some embodiments, the silicone layer is an outwardly convex curved surface.
[0014] In some embodiments, the curved surface is a hemispherical surface, a minor curved surface, or a semi-ellipsoidal surface.
[0015] In some embodiments, the length of the dosing barrel is equal to the length of the push rod. When the push rod fully enters the dosing barrel, the end of the push rod contacts and is flush with the "cross" opening. A handle is provided on the top of the push rod. The width of the handle is greater than the top inner diameter of the dosing barrel so that the handle cannot enter the dosing barrel, thereby ensuring that the capsule or tablet is pushed out of the dosing barrel while preventing the push rod from extending into the dosing barrel.
[0016] In some embodiments, a handle is provided on the top outside of the cartridge.
[0017] In some embodiments, the inner diameter of the top portion of the dosing cartridge is larger than the inner diameter of the bottom portion of the dosing cartridge.
[0018] In some embodiments, the barrel and the push rod of the drug delivery cartridge are both made of plastic.
[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a silicone layer with a "cross" opening at the bottom of the drug delivery barrel, thereby preventing the water-soluble capsule shell or tablet membrane from contacting the animal body fluid too early and causing hydrolysis and denaturation of the capsule or tablet, thereby greatly improving the success rate of drug delivery. At the same time, the present invention cooperates with the brake sheet and the indentation to ensure that the slide rod will not automatically slide to the bottom of the drug delivery barrel, thereby avoiding the risk of the capsule or tablet being accidentally ejected.
[0020] In addition, in some embodiments of the present invention, the braking effect is further improved by evenly arranging a number of indentations on the surface of the push rod and limiting the angle between the brake plate and the cross-section of the dosing barrel; by arranging a handle at the top of the push rod and a handle on the outside of the top of the dosing barrel, the gripping fulcrum is increased to ensure the stability of the dosing process; by enlarging the inner diameter of the top of the dosing barrel, the simplicity of the drug loading process is improved; by improving the material of the barrel body and the push rod of the dosing barrel to plastic, the cost of the dosing device is reduced, and it is disposable to avoid cross infection; by controlling the length of the push rod and the dosing barrel, that is, setting the two to be equal, and setting the width of the handle of the push rod to be larger than the inner diameter of the top of the dosing barrel, it is ensured that when the end of the push rod reaches the "cross" opening, the handle of the push rod is stuck on the outside of the dosing barrel, thereby jamming the push rod to avoid the push rod from accidentally extending out of the dosing barrel into the animal's body and causing unnecessary damage.

[0033] The utility model provides an animal capsule or tablet dispenser, which is mainly used to solve the problems of existing dispensers and provides the following technical solutions. According to the different types of animals, appropriate sizes can be selected. Figure 1-Figure 7 Give detailed instructions:
[0034] Example 1
[0035] This embodiment is a rat drug delivery device. Figure 1 The structure of the animal capsule or tablet dispenser disclosed in this embodiment is shown. The dispenser includes a dosing barrel 1 and a push rod 2. The push rod 2 can be pulled out of the dosing barrel 1 as a whole to put capsules or tablets into the dosing barrel 1. The dosing barrel 1 is 122.5 mm long. A silicone layer 11 is provided at the bottom of the dosing barrel 1. The silicone layer 11 is a semi-elliptical surface with a long radius of 2.5 mm. A "cross" opening 111 is provided in the center of the silicone layer 11. The "cross" opening 111 is normally closed to protect the capsules or tablets in the dosing barrel 1 from falling. When the drug administration action is completed, it is ensured that the capsule or tablet will not contact the body fluid of the animal. When the "cross" opening 111 is applied with external force, it is in an open state. At this time, the capsule or tablet in the drug administration barrel 1 can smoothly slide out of the drug administration barrel 1 and enter the animal's body. A handle 13 is provided on the top outer side of the drug administration barrel 1 to control the stability of the drug loading and drug administration process. A brake sheet 12 is provided on the top inner side of the drug administration barrel 1, and a plurality of indentations 21 are provided on the surface of the push rod 2. The brake sheet 12 and the indentations 21 cooperate with each other to form a braking effect on the push rod 2. Specifically, refer to Figure 2The brake sheet 12 is symmetrically arranged on the inner wall of the top of the dosing tube 1, and the angle α between it and the cross section of the top inner wall of the dosing tube 1 is set to 45°. At the same time, the length of the brake sheet 12 is set to 1.7 mm and the width is set to 1.5 mm (reference Figure 4 ), to ensure that it does not hinder the capsule or tablet from entering the dosing barrel 1 while playing the braking function, the indentations 21 are evenly arranged on the surface of the push rod 2, which cooperates with the brake sheet 12 on the inner side of the top of the dosing barrel 1, that is, the brake sheet 12 presses against the indentations 21, thereby preventing the push rod 2 from automatically sliding to the bottom of the dosing barrel 1 and causing the capsule or tablet to slide out accidentally; the diameter of the barrel body of the dosing barrel 1 is set to 3mm, so that it can accommodate multiple capsules or tablets at the same time, realizing one-time multi-pill dosing, thereby reducing the number of dosing times for animals and improving dosing efficiency; the diameter of the top of the dosing barrel 1 is set to 6mm, and the diameter of the top of the dosing barrel 1 is larger than the diameter of the barrel body, so as to facilitate the entry of capsules or tablets into the dosing barrel 1; reference Figure 3 The length of the push rod 2 is set to 122.5mm, and a handle 22 is provided at the top of the push rod 2. The handle 22 is set to a semi-elliptical ring with a short diameter of 20mm. Since the length of the push rod 2 is equal to the length of the dosing barrel 1, when the push rod 2 is pushed to the bottom of the dosing barrel 1, the push rod 2 contacts and is level with the "cross" opening 111 to ensure that the capsule or tablet is pushed out of the dosing barrel 1. At the same time, the width of the handle 22 is greater than the inner diameter of the top of the dosing barrel 1, so that the handle 22 can be stuck on the outside of the dosing barrel 1 when the capsule or tablet is pushed out of the dosing barrel 1, thereby preventing the push rod 2 from being pushed out of the dosing barrel 1 and contacting the stomach or esophagus of the animal, thereby causing unnecessary damage; the barrel body of the dosing barrel 1 and the push rod 2 are both made of plastic to reduce the cost of the dosing device, achieve disposable use, and avoid cross infection; reference Figure 7 , the diameter of the push rod 2 is 2.5 mm.
[0036] Example 2
[0037] In this embodiment, the silicone layer is configured as an outwardly protruding hemispherical surface with a radius of 1.5 mm, and the rest is the same as in Embodiment 1.
[0038] Example 3
[0039] In this embodiment, the silicone layer is an outwardly convex inferior arc surface, and the rest is the same as that of the first embodiment.
[0040] Example 4
[0041] In this embodiment, a rubber layer is provided at the bottom end of the push rod. The diameter of the rubber layer is equal to the diameter of the inner wall of the barrel of the dosing barrel. The shape of the rubber layer is the same as that of the silicone layer. The rest is the same as that of Example 1.
[0042] The above describes in detail the preferred embodiments of the present invention. It should be understood that numerous modifications and variations based on the concepts of the present invention can be made by those skilled in the art without inventive effort. Therefore, any technical solution that can be derived by a person skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology shall be within the scope of protection defined by the claims.
