Description

Technical Field

[0001] This utility model relates to the field of medical or veterinary technology, and in particular to an enteric-coated empty capsule. Background Technology

[0002] Enteric-coated empty capsules are a special drug dosage form, consisting of empty capsules made from enteric-coating materials. These capsules are designed to remain insoluble in the acidic environment of the stomach, but instead begin to dissolve in the alkaline environment of the intestines (usually the small intestine), thus releasing the drug inside.

[0003] Enteric-coated empty capsules include enteric materials, drug protection, targeted release, taste and odor masking, and controlled release rate. The enteric material, the outer shell of the enteric-coated capsule, is made of a material that remains insoluble in gastric acid but dissolves in the alkaline environment of the intestine. Common enteric materials include hydroxypropyl methylcellulose phthalate (HPMCAS) and acrylic resins.

[0004] Existing enteric-coated empty capsules release the drug at specific points in the intestines after passing through the stomach, thus avoiding drug degradation in gastric acid and improving drug bioavailability and efficacy. However, for some patients, such as the elderly, children, or those with difficulty swallowing, traditional enteric-coated empty capsules may be difficult to swallow, leading to inconvenience and limiting the flexibility of the capsules. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an enteric-coated empty capsule that can solve the problem that traditional enteric-coated empty capsules are difficult to swallow for some patients, such as the elderly, children or patients with difficulty swallowing, which leads to inconvenience in taking the capsule and thus limits its flexibility.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an enteric-coated empty capsule, comprising an upper cap, a first container shell, a lower cap, a second container shell, and a third container shell, wherein two second limiting strips are fixedly connected to the lower outer wall of the first container shell, and two second limiting strip grooves are formed on the lower inner wall of the upper cap, and the lower outer wall of the first container shell is slidably connected to the inner wall of the upper cap.

[0007] Among them, the outer walls of the two second limiting strips respectively contact the inner walls of the corresponding second limiting strip grooves, and the lower surface of the first container shell is provided with a third container shell groove, and the outer wall of one end of the third container shell is slidably connected to the inside of the third container shell groove.

[0008] The upper outer wall of the second container shell is slidably connected to the upper inner wall of the lower shell cover, and two third limiting grooves are provided on the upper inner wall of the lower shell cover.

[0009] The outer wall of the second container shell upper end is fixedly connected with two third limiting strips, and the outer walls of the two third limiting strips are respectively in contact with the inner walls of the corresponding third limiting strip grooves.

[0010] Preferably, the upper surface of the second container shell is provided with the same third container shell groove.

[0011] The outer wall of the third container shell away from the first container shell is slidably connected with the inner part of the third container shell groove on the second container shell.

[0012] Preferably, the upper surface of the second container shell is provided with the same third container shell groove.

[0013] The outer wall of the third container shell away from the first container shell is slidably connected with the inner part of the third container shell groove on the second container shell.

[0014] Preferably, the upper surface of the second container shell is provided with the same third container shell groove.

[0015] The outer wall of the third container shell away from the first container shell is slidably connected with the inner part of the third container shell groove on the second container shell.

[0016] Preferably, the outer wall of the first container shell lower end protrusion is fixedly connected with two first limiting strips.

[0017] The upper surface of the second container shell is provided with a limiting groove.

[0018] Preferably, the outer wall of the first container shell lower end protrusion is slidably connected with the inner part of the limiting groove, and the inner part of the limiting groove is provided with two third container shells.

[0019] The outer walls of the two first limiting strips are respectively in contact with the inner walls of the corresponding third container shells.

[0020] Compared with the prior art, the utility model has the advantages that:

[0021] 1、The enteric hollow capsule, through first container shell and second container shell are pulled when the capsule is taken, the first limiting strip and the inner part of the first limiting strip groove are separated from the contact, so that the third container shell in the first container shell and the second container shell can be taken out and taken alone, then the first container shell upper end outer wall and the inner wall of the upper shell cover form the first container cavity, and the second container shell lower end outer wall and the inner wall of the lower shell cover form the second container cavity, so that the upper shell cover and the lower shell cover can be taken alone, which effectively reduces the difficulty of taking, and further effectively reduces the size of the capsule, avoids the difficulty of swallowing of the elderly, children or patients with difficulty in swallowing, and further improves the flexibility of the capsule.
