The utility model will be described in detail below with reference to the drawings in connection with embodiments.
The slow release type capsule comprises a capsule body 1 and a rubber cap 2 sleeved on the capsule body, wherein the capsule body comprises a middle medicine storage section 3 and a tail medicine storage section 4, and a tail medicine storage cavity 5 is arranged in the tail medicine storage section; the rubber cap comprises a middle sleeve section 6 and a head medicine storage section 7, and a head medicine storage cavity 8 is arranged in the head medicine storage section; the middle part sleeve section suit is in the middle part medicine storage section outside, and middle part sleeve section inner wall and middle part medicine storage section outer wall laminating, and the inside several baffle that separates that is equipped with of middle part medicine storage section for middle part medicine storage section inner chamber forms a plurality of (level) slowly-releasing medicine storage chamber 9, and the total wall thickness of middle part medicine storage section and middle part sleeve section cooperation department (the sum of both lateral wall thickness) both is greater than head medicine storage section wall thickness, is greater than afterbody medicine storage section wall thickness again.
In an alternative embodiment, the side of the capsule body, which is different from the tail medicine storage section, is provided with an opening structure 11, the baffle plates close to the opening structure are obliquely arranged inwards, and the baffle plates which are obliquely arranged at the outermost side are more beneficial to medicine filling. In yet another alternative embodiment, as shown in fig. 6, a sealing plate 16 is provided at the end of the capsule body opposite to the tail medicine storage section, so as to seal the opening structure of the capsule body, and prolong the release time of the medicine in the capsule body through the side.
The length of the middle sleeve section is the same as that of the middle medicine storage section, or the length of the middle sleeve section is slightly shorter than that of the middle medicine storage section by 1-3mm, the middle sleeve section can effectively cover the middle medicine storage section of the capsule body, no protruding part exists, the wall thickness of the middle medicine storage section of the capsule body is thickened by the middle sleeve section of the rubber cap, the medicine release time in the middle medicine storage section is delayed, medicine passing gaps 10 are reserved between each baffle and the inner wall of the medicine storage section, the gaps are used for filling medicines during production, and after the medicines are taken, gastric juice or intestinal juice of a patient enters the slow-release medicine storage cavity through the gaps, so that the medicines are gradually dissolved and slowly released.
The hollow area of the medicine passing gap is 1/2-1/4 of the cross-sectional area of the inner cavity of the middle medicine storage section, and the structural design is convenient for loading medicines in production and is beneficial to maintaining the slow release state of the medicines in use.
Generally, the side wall of the head medicine storage section of the rubber cap and the side wall of the tail medicine storage section of the capsule body are dissolved in advance, namely, the medicines in the head medicine storage cavity and the tail medicine storage cavity exert medicine effects first. In a further improved scheme, the wall thickness of the head medicine storage section is designed to be smaller than that of the tail medicine storage section, in the scheme, the side wall of the head medicine storage section is dissolved before the side wall of the tail medicine storage section, namely, medicines in the head medicine storage cavity exert efficacy before medicines in the tail medicine storage cavity, and medicines in the head medicine storage cavity, the tail medicine storage cavity and the slow-release medicine storage cavity exert efficacy in sequence after a patient takes medicines, so that the slow-release effect is more ideal.
Because the rubber cap is used for dissolving the thickened part of the capsule body for a longer time, before the side wall of the middle medicine storage section is undissolved, medicine can only be released from the two sides of the capsule body along the medicine passing gap. In an alternative embodiment, the barrier comprises two middle barriers 12 at the inner side, and an outer barrier 13 arranged corresponding to the outer side of each middle barrier, respectively; the medicine passing gap between the middle baffle plate and the inner wall of the medicine storage section is smaller than the medicine passing gap between the outer baffle plate and the inner wall of the medicine storage section, a second-level slow-release cavity 14 is formed between the two middle baffle plates, a first-level slow-release cavity 15 is formed between each middle baffle plate and the outer baffle plate outside the middle baffle plate, and the wall thickness of the medicine storage section at the tail part is 1.5-2 times of the wall thickness of the medicine storage section at the head part; the total wall thickness of the matched part of the middle medicine storage section and the middle sleeve section is 1.5-2 times of the wall thickness of the tail medicine storage section. In the scheme, the medicine in the slow-release medicine storage cavity also forms a two-stage medicine effect release process, and the slow-release performance is better.
The utility model has reasonable structural design, and leads the medicine in the head medicine storage cavity, the tail medicine storage cavity and the slow-release medicine storage cavity to exert medicine effects to form a sequence through various slow-release structures, thereby prolonging the time of exerting medicine effects and ensuring ideal slow-release effect after patients take medicine. Especially for the medicine with large gastrointestinal irritation or the crowd sensitive to the dosage, the slow-release capsule can be taken, and adverse reactions of organs such as intestines and stomach can be reduced while the curative effect is ensured.
The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the present utility model, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
