Background
Allergic diseases such as asthma and rhinitis are often treated by using inhalation drugs, for example, powdered or granular drugs are placed in drug blister strips of a sandwich structure, drug blisters are sequentially conveyed to a joint member through a drug powder releasing device, the drug blister strips are punctured or uncovered, and then the drugs are inhaled into the mouth, nose or lung of a patient through an inhalation mode to achieve the purpose of treatment.
A powder releasing apparatus of the above type is disclosed in US 6792945B 2, wherein the powder releasing apparatus comprises a cap housing and a housing, the housing is composed of a top case and a bottom case, an mouthpiece for sucking out powder and a slide lever for releasing the powder are provided outside the housing, two rotary shaft protrusions are provided on both sides of the top case and the bottom case, respectively, the cap housing has two rotary holes, the two rotary shaft protrusions on the bottom case are inserted into the rotary holes on the cap housing, respectively, the cap housing is detachable from the housing and remounted, and the cap housing and the housing are rotated about a line connecting the two rotary shaft protrusions to cover or expose the mouthpiece in a state where the cap housing is mounted to the housing.
When the cover sleeve is installed on the shell, the interface piece and the sliding rod can be exposed or covered by rotating the cover sleeve, the interface piece is a medicine powder release opening contacting with a human body, and the sliding rod is a switch for puncturing or uncovering medicine bubbles and sequentially transmitting the medicine bubbles to the interface piece according to a certain step pitch. After the medicine powder releasing device is used, the sliding cover is sleeved to cover the interface piece and the sliding rod so as to avoid polluting the interface piece and triggering the sliding rod to cause misoperation.
The powder release device in the prior art has the following defects:
first, since the housing of the powder discharge apparatus is generally shaped like a circular cake without any obvious marks, and the cap cover needs to be fitted over the housing at a specific position for normal use, the user may have trouble in which position of the housing the cap cover is fitted.
Secondly, since the whole of the housing of the powder discharge apparatus is substantially symmetrical in a circular cake shape, the user needs to look over the cap housing protrusion inside the cap housing in advance and distinguish the bottom case from the top case to correctly mount it on the housing, and since the cap housing protrusion inside the cap housing is not obvious, great inconvenience is caused to the user.
Finally, before the rotating shaft of the cover sleeve is embedded into the rotating hole of the shell, the cover sleeve needs to be broken off by external force to a certain caliber to be placed in, and two hands are usually required to be used for simultaneous processing for a user, so that the user is inconvenient to vacate hands to place the shell into the cover sleeve after the cover sleeve is unfolded, and the rotating shaft of the shell is further embedded into the rotating hole of the cover sleeve.

fig. 1 is a schematic view showing an external construction of a drug powder releasing device according to an embodiment of the present invention;
fig. 2 is an exploded perspective view of the drug powder releasing device of fig. 1, showing an upper portion of the top case;
fig. 3 is a schematic view showing the lower structure of the bottom case of the drug delivery device according to an embodiment of the present invention.
Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
Referring to fig. 1-2, there is shown a schematic diagram of a drug delivery device according to an embodiment of the present invention, which is a delivery device for delivering a powdered or granular drug, particularly for inhalation of a powdered drug for asthma, in an exploded perspective view. The basic principle of the drug powder releasing device shown in fig. 1-2 is similar to that of the prior art, and those skilled in the art can easily understand the mounting and using principle of the drug releasing strip of the present invention through the prior art provided by the background art, and the detailed description thereof is omitted.
Referring to fig. 1-2, the drug delivery device of the present invention comprises at least a housing 4, the housing 4 is formed by fastening a top shell 41 and a bottom shell 42, a drug delivery band (not shown) is disposed inside the housing 4, a mouthpiece 1 for sucking out drug powder and a sliding rod 2 for releasing drug powder are disposed outside the housing 4, and a cover 3 capable of rotating around a rotation axis of the housing 4 to cover or expose the mouthpiece 1 and the sliding rod 2 is detachably mounted outside the housing 4. Since the main structural improvement of the present invention is between the housing 4 and the cover 3, the structure inside the housing 4 is omitted from fig. 2.
The shell 4 and the cover sleeve 3 are of detachable structures, the shell is formed by buckling a top shell and a bottom shell, and the top shell and the bottom shell can be detached to open the internal structure of the medicine powder releasing device.
In view of the above-mentioned drawbacks of the prior art, the present invention provides an improvement, and more particularly, the aforementioned hinge of the present invention is formed by an upwardly protruding top-case protrusion 411 on the top case 41 and a downwardly protruding bottom-case protrusion 412 on the bottom case 42 (see fig. 3), the cover 3 has a top hinge hole 31 matching the shape of the top-case protrusion 411 and a bottom hinge hole (not shown) matching the shape of the bottom-case protrusion 412, and at least one of the top-case protrusion 411 and the bottom-case protrusion 412 is provided with a slant at its end.
Therefore, the inclined planes can be additionally arranged on the top shell bulge 411 or the bottom shell bulge 412 of the top shell 41 and the bottom shell 42, when the cover sleeve 3 is installed on the shell 4, the distance between the tail ends of the two bulges 411 and 422 is larger than the caliber of the cover sleeve 3, and certain obstruction can be caused to installation. In fig. 3, the cover 3 is omitted for clarity, and a person skilled in the art can obtain the corresponding bottom rotary hole related structure from the exploded perspective view of fig. 2 and the top rotary hole 31, so that fig. 3 does not show the bottom rotary hole.
Further, in a preferred embodiment, as shown in fig. 2 and 3, a slope may be provided at the end of each of the top case protrusion 411 and the bottom case protrusion 412, that is, a first slope 4111 and a second slope 4221 may be provided, and the first slope and the second slope preferably face in the same direction. When the cover sleeve 3 is installed on the shell 4, the opening of the cover sleeve 3 is installed opposite to the inclined plane directions of the top shell protrusion 411 and the bottom shell protrusion 412, the inclined plane directions of the top shell protrusion 411 and the bottom shell protrusion 412 can play an indicating role in installation, the situation that the installation position is difficult to determine due to the fact that the shell 4 is circular is avoided, and installation is simpler
In another preferred embodiment, as shown in figures 2 and 3, the top shell protrusion 411 and the bottom shell protrusion 412 are located on the same axis, so that the cover 3 can be rotated about one axis instead of two, avoiding jamming. More preferably, the top protrusion 411 and the bottom protrusion 412 have different sectional diameters, and the user can visually check the sectional diameters of the top protrusion 411 and the bottom protrusion 412 and the diameters of the top rotation hole 31 and the bottom rotation hole to determine whether the cover 3 is matched with the housing 4 for one-time correct installation.
In conclusion, the medicine release device not only enables a user to find an accurate position to place the cover sleeve on the shell more easily, but also is easy to distinguish the front side and the back side in the placement process, simple and labor-saving, only needs to enable the inclined surface protruding from the rotating shaft on the shell to face the cover sleeve, utilizes the inclined surface to prop open the cover sleeve, and directly inserts the shell into the cover sleeve.
