Abstract

The utility model discloses a capsule type dry powder suction device, which comprises a box cover, a bottom disk and an opening sucking machine which is provided with a suction nozzle, a sieve and a buckle and can rotate round a rotary shaft, wherein the bottom disk comprises a current rotary cabin, a capsule groove, two elastic buttons which are symmetrically arranged on both sides of the bottom disk and small holes. The rotary shaft and the opening sucking machine are integral, and the rotary shaft is inserted into a shaft hole of the bottom disk. The opening sucking machine is together connected with a buckling groove on the bottom disk through the buckle. The bottom disk also comprises six pricking pin through holes and six pricking pins, the six pricking pin through holes are respectively and symmetrically arranged on the side walls of both ends of the capsule groove and the six pricking pins are respectively fixed on the two buttons. The diameter of an outer circle formed by three pricking pins on each side is smaller than the diameter of the top end of a capsule. The utility model has the advantages that the utility model has simple structure, convenient use and convenient operation, can easily puncture capsules and effectively increases the emptying rate of dry powder, etc. The utility model can be widely used as a medicine feeding device for medicine suction of patients who have the diseases such as tracheitis, bronchitis, throat diseases, asthma, etc.

Description

A kind of capsule type dry powder suction apparatus

Technical field

This utility model relates to a kind of medicinal inhalation devices, particularly a kind of capsule type dry powder suction apparatus.

Background technology

At present, a kind of Diskus is arranged, this Diskus comprises lid, mouth haustorium and chassis, the mouth haustorium comprises buckle, suction nozzle, screen cloth, swivelling cover and axle, the chassis comprises the air-flow rotatable cabin, the capsule groove, two buttons, spring, axis hole, gas channel, the pricker through hole, two root thorn pin and shells, buckle and screen cloth lay respectively at a side and the bottom of swivelling cover, axle is vertical with swivelling cover, button and spring constitute the elastic reset button mechanism that is installed on shell, axle constitutes the mechanism that mouthful haustorium can only be pivoted with axis hole, two root thorn pin through holes are symmetricly set on the both sides of capsule groove respectively, pricker and pricker through hole constitute the mechanism that when pressing button pricker passes through in the pricker through hole, and a mouthful haustorium snaps together by buckle and shell.Take off lid when the patient uses, one holds the chassis, and another hands rotates the mouth haustorium towards counter clockwise direction: keep flat in the capsule groove containing Drug Capsule; Rotate a mouthful haustorium toward the clockwise direction, extremely the buckle of mouthful haustorium blocks the chassis catching groove; The pressing button makes two groups of prickers move toward one another thereupon, stretches into the capsule groove, punctures capsule; The patient puts into the oral cavity with the mouth haustorium, comes back, and this Diskus is inverted; (contain Drug Capsule; The patient exhales earlier, and is then air-breathing with strength; Air pours in the air-flow rotatable cabin through gas channel, contains the Drug Capsule rotation, and the powder in the capsule is subjected to centrifugal force from acanthopore ejection atomizing, and atomized powder is crossed screen cloth with air communication and entered the oral cavity through suction nozzle, through therapentic part.The shortcoming of prior art is: every end of capsule groove has two root thorn pins, and during use, if undue force is difficult to guarantee to puncture the capsule both sides, the pastille powder is from all emptyings of side acanthopore, and the patient can not reach should be effective in cure.

Summary of the invention

Problem to be solved in the utility model be release a kind of simple in structure, easily evenly puncture capsule when using, and do not produce the capsule fragment and be easy to medicated powder is sucked the capsule type dry powder suction apparatus of therapentic part.

The technical scheme of this utility model technical solution problem is as follows:

A kind of capsule type dry powder suction apparatus, comprise lid, have suction nozzle, the mouth haustorium and the chassis that can rotate around the shaft of screen cloth and buckle, described chassis comprises the air-flow rotatable cabin, the capsule groove, two elastic button and apertures that are symmetricly set on the both sides, chassis, described rotating shaft is an one with a mouthful haustorium, the chassis upper shaft hole is stretched in described rotating shaft, the mouth haustorium links together by the catching groove on buckle and the chassis, described chassis also comprises six pricker through holes and six roots of sensation pricker, six pricker through holes are symmetricly set on respectively on the sidewall of capsule groove two ends, six roots of sensation pricker is individually fixed on two buttons, and the formed outside diameter of every side three root thorn pins is less than the capsule top end diameter.

This utility model can evenly puncture capsule from three directions by in capsule groove both sides 3 root thorn pins being set respectively.Thereby what solved that existing suction apparatus exists causes defectives such as capsule can't puncture because of unbalance stress, and three the root thorn needle construction rationally distributed, therefore whole suction apparatus has simple in structurely, easy to use, and operation is convenient, can easily puncture capsule, effectively improve the advantages such as Emptying Rate of dry powder, can be widely used as the doser of inhalation, supply such as tracheitis, bronchitis, throat disease, the patient of diseases such as asthma uses.

The specific embodiment

Further specify this utility model below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 3 and Fig. 4, a kind of dust cloud inhaler of this utility model, comprise lid 1, have suction nozzle, the mouth haustorium 2 and the chassis 3 of 12 rotations around the shaft of screen cloth 7 and buckle 8, described chassis 3 comprises air-flow rotatable cabin 4, capsule groove 5, two elastic button 6 and apertures that are symmetricly set on the both sides, chassis, described rotating shaft 8 is an one with a mouthful haustorium (2), chassis (3) upper shaft hole is stretched in described rotating shaft 8, mouth haustorium 2 links together by the catching groove 9 on buckle 8 and the chassis, described chassis 3 also comprises six pricker through holes 10 and six roots of sensation pricker 11, six pricker through holes 10 are symmetricly set on respectively on the sidewall of capsule groove two ends, six roots of sensation pricker 11 is individually fixed on two buttons, and the formed outside diameter of every side three root thorn pins is less than the capsule top end diameter.

Referring to Fig. 4, three root thorn pins of described every side become the equilateral triangle setting, and the both sides pricker forms two straight lines that leg-of-mutton center connects and overlaps with capsule straight line that the center connects.
