Abstract

The utility model discloses a medicine powder inhaler for dry powder inhalant, mainly comprising a dustproof cover, an oral inhaler and a base disc, wherein, the oral inhaler consists of a buckle, a suction nozzle, a sieve and a rotary axle. And the base disc comprises an air flow rotating cabin, a capsule cabin, two buttons, a spring and a piercing needle, etc. The utility model reduces the strength needed during the patient punctures the capsule shell, favors the usage of the old and children and reinforces the adaptability of the patient, thus the capsule shell can be pierced in an easier manner, and the fragments produced after the capsule shell is pierced can be connected with the capsule shell without falling down, so as to reduce the fragments of the capsule shell and prevent the patient from choking or the respiratory tract from being hurt caused by that the fragments of the capsule shell enters the respiratory tract following the medicine powder.

Description

A kind of medicated powder inhaler

Technical field

This utility model relates to a kind of medicated powder inhaler, is used as in the utensil of capsule type dry powder inhalant administration, belongs to medical apparatus and instruments.

Background technology

A kind of medicated powder inhaler is arranged in the background technology, and this medicated powder inhaler comprises dust cap, mouthful haustorium and chassis, and a mouthful haustorium comprises buckle, suction nozzle, screen cloth, rotating shaft, and the chassis comprises air-flow rotatable cabin, capsule cabin, two buttons, spring, pricker etc.Take off dust cap when the patient uses, one holds the chassis, and another hands towards rotation counterclockwise, is opened the capsule cabin with suction nozzle; To contain Drug Capsule lies in the capsule cabin; Rotate suction nozzle toward the clockwise direction, close the capsule cabin; Pressing button makes two groups of prickers move toward one another thereupon, punctures capsule; The patient exhales earlier, suck suction nozzle, FI then, capsule enters in the air-flow rotation storehouse of screen cloth below, air pours in air-flow rotation storehouse through gas channel, and capsule rolls thereupon, and the medicated powder in the medicine bag is spread out from acanthopore by centrifugal action, cross screen cloth with air communication and enter the oral cavity, enter pulmonary through suction nozzle.The shortcoming of background technology is: 1, adopted 4 springs, connected button and pricker, made needs of patients with big strength, just can puncture capsule shells, be unfavorable for that old man and child patient use.2, the tip portion of pricker is common needle-like, and the fragment that produces when puncturing capsule is more, after fragment enters respiratory tract, causes easily that choking of patient coughed or to the damage of respiratory tract.

Summary of the invention

The purpose of this utility model provides a kind of medicated powder inhaler, to reduce the fragment that produces when capsule shells is punctured, reduces patient simultaneously and punctures the required strength of capsule shells.

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

A kind of capsule-type medicated powder inhaler comprises dust cap, suction nozzle, buckle, screen cloth, chassis.Described chassis comprises the air-flow rotatable cabin, capsule cabin, two buttons that are symmetricly set on the both sides, chassis, each button respectively is fixed with a root thorn pin, and spring of cover makes pricker pass spring center on the pricker, thereby solved in the prior art because parallel four springs of employing, make the patient need just can puncture capsule shells, and adopt this utility model, reduced patient to puncture the required strength of capsule shells with bigger strength, make things convenient for old man and child to use, strengthened compliance of patients.

This capsule-type medicated powder inhaler, pricker are real core or hollow, compare with common pin, and needle point position (real core or hollow) has an oblique section, and shape is seen Fig. 4.This utility model, make that capsule shells is easier to be punctured, and helping capsule shells is punctured the fragment that the back produces and is connected on the capsule shells, and can not fall down, thereby reduced the generation of fragment, avoided the capsule shells fragment to enter with medicated powder that choking of may causing behind the respiratory tract coughed or the damage of respiratory tract.This simplicity of design, pricker puncture capsule shells easily, do not produce fragment, when the patient was air-breathing, air entered rotatable cabin through gas channel, contained Drug Capsule and rotated in the capsule cabin, medicated powder in the capsule is flown out from the hole that punctures by centrifugal action, effectively improves the Emptying Rate of medicated powder.

The specific embodiment

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

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, this utility model is a kind of medicated powder inhaler, comprises dust cap 1, suction nozzle 2, screen cloth 3, buckle 4, rotating shaft 5, air flow inlet 6, air-flow rotatable cabin 7, capsule cabin 8, two buttons 9, and button comprises spring 91, pricker 92 etc.

Open dust cap 1, expose suction nozzle 2, slightly firmly open buckle 4, the suction nozzle that turns clockwise exposes capsule cabin 8, and the capsule that medicated powder is housed is put into the capsule cabin, during pressing button 9, spring 91 drives pricker 92, makes two groups of prickers move toward one another thereupon, punctures the medicine-carrying capsule that is positioned at the capsule cabin, capsular two ends respectively produce an acanthopore, the patient exhales earlier, then with sucking suction nozzle, FI, capsule enters air-flow rotatable cabin 7 from capsule cabin 8, air enters air-flow rotatable cabin 7 from air flow inlet 6, and capsule is under the effect of air flow, at air-flow rotatable cabin internal rotation, medicated powder in the capsule is subjected to centrifugal action, spread out from acanthopore, cross screen cloth with air communication and enter the oral cavity, enter pulmonary through suction nozzle.

Adopt this utility model, needed strength was less when the patient punctured capsule shells, and after capsule shells is punctured, do not produce fragment, had avoided the capsule shells fragment to enter with medicated powder that choking of may causing behind the respiratory tract coughed or to the damage of respiratory tract.This medicated powder inhaler Emptying Rate height, pulmonary deposition rate height, can not produce capsule is stuck in the capsule cabin and can not rotates, and medicine can't be delivered to the situation of lesions position, can be widely used as the doser of Foradil Aerolizer formoterol fumarate, for asthma, the patient of diseases such as chronic obstructive pneumonia, throat uses, or is used for the inhalation utensil of protein and peptide drugs such as insulin (diabetes are used), avian influenza vaccine.
