Abstract
The disclosed capsule-sting device for a capsule-type dried power inhaler comprises a sting pin on capsule slot side to sting the capsule on side surface instead of current on ends. This invention enlarges greatly the distance between sting pins to avoid the danger as high pin density, and simplifies the structure of inhaler.
Description
Technical field
The present invention relates to a kind of capsule type dry powder inhaler, particularly a kind of capsule of capsule type dry powder inhaler punctures mode and lancing device.
Background technology
The existing Diskus that generally uses, its structure mainly comprise lid, mouthful haustorium and chassis as shown in Figure 1.The chassis is provided with capsule groove and capsule lancing device, and a mouthful haustorium is provided with suction nozzle and screen cloth, and the inner chamber of mouthful haustorium is connected with the capsule groove on the chassis.Described lancing device includes pricker, button and spring.When the capsule that is arranged in the capsule groove is punctured device and punctures, but the patient just the suction nozzle on the through port haustorium powder in the capsule is sucked.
The shortcoming of this Diskus is: because the pricker of the lancing device on the capsule groove is distributed in the two ends of capsule groove, that is to say from capsular two ends to puncture capsule.This mode that punctures, owing to carry out from capsular two ends, therefore if capsule is punctured and is convenient to the words of capsule Chinese medicine powder sucking-off, then must be provided with pricker at the two ends of capsule groove, simultaneously because pricker is arranged at capsular two ends, so far apart between between the pricker at two ends like this, therefore two lancing device can only be set at capsular two ends, can thrust the pricker at capsule two ends from two ends and can't on a lancing device, install simultaneously, it is complicated that thereby the structure that makes inhaler becomes, simultaneously for the ease of the medicated powder sucking-off, often need arrange the pricker more than at the two ends of capsule groove, and because capsular end is less, so just be easy to cause medicine bag shell between each pricker may form fragment and sneak in the medicated powder, along with medicated powder sucks trachea, cause danger to user.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part and a kind of lancing device of simplifying Diskus is provided, the capsule that can improve the capsule type dry powder inhaler that punctures effect simultaneously punctures mode.
Another object of the present invention also is the corresponding capsule lancing device of the mode that punctures that provides a kind of and above-mentioned.
The capsule mode of puncturing of capsule type dry powder inhaler provided by the invention is: the pricker of the lancing device of described capsule type dry powder inhaler is to be thrust in the capsule groove by the side of capsule groove.
Described puncturing is to carry out from the side of capsule groove with multiple-point form.
A kind of lancing device of capsule type dry powder inhaler, its structural feature is: the pricker of described lancing device is arranged at the side of capsule groove, and lancing device is provided with at least one pricker.
The pricker of the lancing device of capsule type dry powder inhaler is arranged at the side of capsule groove, capsule is being put into the capsule groove like this, when starting lancing device, capsule will be punctured by capsular side by the capsule lancing device, medicated powder in the capsule that is punctured carries out when air-breathing facing to mouthful air-breathing the patient, to bring the oral cavity into by the air-flow that the air-breathing air flow passage of mouth flows into, through therapentic part.The capsule groove lancing device of this form and puncture mode, owing to be the lateral of the capsule groove that to be built up in, just be arranged on capsular side (being capsular outer peripheral face), and capsular side has the area times over the capsule end face, therefore it is when the pricker of distribution equivalent amount, have the distance that is several times as much as the end pricker between each pricker, so it can be avoided because of the overstocked harm that brings of pricker distribution.
Described lancing device is arranged at the side of capsule groove.
Whole lancing device is arranged at the side of capsule groove, then only a lancing device need be set and get final product, so can simplify the structure of mouthful haustorium greatly in the same side of capsule groove.
The lancet tip of described lancing device is a wedge shape.
Pricker on the described lancing device is arranged along the axis direction of capsule groove.
Pricker on the described lancing device is 2,3 or 4.
Described lancing device comprises button, spring and pricker, described pricker one end is fixed on the button, and the other end then can debouch the pricker through hole of capsule groove sidewall, also is provided with spring simultaneously on pricker, one end of spring is supported on the button, and the other end then is supported in the outer wall of capsule groove.
Directly spring housing is contained on the pricker, utilizes a plurality of prickers of arranging on it to fix button simultaneously, can simplify the structure of lancing device greatly, reduce the manufacturing process and the cost of inhaler.
The button of described lancing device slides on the slot of capsule groove outer wall.
Button is slided on the slot that is arranged at capsule groove outer wall, can further stablize button and make it by default movement locus motion.
In sum, the present invention has following advantage compared to existing technology:
Owing to being changed into from the side of present capsule groove by the original two ends from capsule groove groove, the capsule mode that punctures with the capsule type dry powder inhaler carries out, so just can increase the distance between each pricker in the unit are greatly, therefore can avoid because of the overstocked harm that brings of pricker distribution; Because lancing device is the side that is installed on the capsule groove, therefore only a lancing device need be set and gets final product simultaneously, therefore can simplify the structure of Diskus in the same side of capsule groove.

Fig. 2 is the structural representation of most preferred embodiment of the present invention
The specific embodiment
Below in conjunction with embodiment the present invention is described in more detail.
Most preferred embodiment:
The capsule of capsule type dry powder inhaler punctures mode, and the pricker of described lancing device (221) is the capsular side of thrusting capsule groove inside from the side (213) of the capsule groove of Diskus in multiple-point mode.Described lancing device is for as shown in Figure 2, and it is arranged at the side (213) of the capsule groove on the Diskus chassis.It vertically is arranged with two pricker (221) in the lancing device upper edge, described lancing device (22) comprises button (222), spring (223) and pricker (221), one end of pricker is fixed on the button, the other end then can debouch the through hole (211) of capsule groove sidewall, on pricker (221), also be provided with simultaneously spring (223), one end of spring is supported on the button, and the other end then is supported in the outer wall of capsule groove, and button slidably slides on the slot (214) of capsule groove outer wall.
