Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a capsule-breaking mechanism of a powder aerosol drug delivery device. Background Art

[0002] Respiratory disease is a common disease. With the deterioration of air quality, the incidence of respiratory disease is increasing, especially chronic respiratory disease, which will bring patients a high pain index. At present, the main and most effective ways to treat chronic respiratory diseases in hospitals are metered dose inhalation aerosols, dry powder inhalers, and nebulized inhalers. Dry powder inhalers are also called powder inhalers. The delivery device of powder inhalers is the powder inhaler delivery device.

[0003] Patent No. CN105920709B discloses a capsule-breaking mechanism for a powder inhaler drug delivery device, comprising a drug chamber containing a powder inhaler capsule and a needle penetrating the inner wall of the chamber. The needle's tip faces the chamber and is located at the location of the powder inhaler capsule. A button is provided at the other end of the needle, located outside the chamber. The chamber holds the powder inhaler capsule upright. The button has at least two needles, at least one of which is located at the top of the powder inhaler capsule and at least one of which is located at the bottom of the powder inhaler capsule. The needle tip at the top of the powder inhaler capsule is offset relative to the needle tip at the top of the powder inhaler capsule. Because the two needles on the button are arranged vertically and offset left and right, the powder inhaler capsule stands upright, resulting in a 100% emptying rate of the powder inhaler capsule during drug administration, a local deviation in the powder inhaler gas concentration of less than 1%, and a consistency of over 99% in the drug administration effect throughout the entire course of treatment.

[0004] When using the existing device, the puncture device often directly penetrates the entire capsule and then uses the through holes at the top and bottom of the capsule to absorb the powder inside the capsule. This method causes the entire puncture needle to enter the interior of the capsule, thereby compacting the powder inside the capsule, which is not conducive to the patient's subsequent washing out of the powder during aspiration. In addition, the puncture needle will bring some of the powder out of the capsule, causing waste.

[0005] Therefore, the present application provides a capsule-breaking mechanism for a powder aerosol delivery device to meet the needs. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example

[0033] like Figure 1 As shown, the embodiment of the present invention provides a capsule-breaking mechanism for a powder aerosol delivery device, comprising a housing 1, a clamping mechanism 2 provided on one side of the housing 1, a puncture mechanism 3 provided on one side of the clamping mechanism 2, a dust cover 4 movably mounted on the top of the housing 1, a top cover 5 fixedly mounted on the top of the housing 1, and a nozzle 6 fixedly mounted on the top of the top cover 5;

[0034] like Figure 3 、 Figure 4 and Figure 5 As shown, the clamping mechanism 2 includes a rotating plate 201, a rotating shaft 202, a limiting plate 203, a bottom plate 204, a sliding groove 205, a first spring 206, a pressure plate 207, a slider 208, a first rotating block 209, a second rotating block 210 and a positioning shaft 211. The rotating plate 201 is movably mounted on one side of the housing 1 through the rotating shaft 202. The limiting plate 203 is fixedly mounted on one side of the rotating plate 201. The bottom of the limiting plate 203 is fixedly mounted with the bottom plate 204. The rotating plate 201 A sliding groove 205 is provided on one side, the top of the bottom plate 204 is fixedly connected to the first spring 206, the top of the first spring 206 is fixedly connected to the pressure plate 207, one side of the pressure plate 207 is fixedly connected to the slider 208, the slider 208 is movably connected between the first rotating block 209 and the second rotating block 210, the bottom of the first rotating block 209 and the second rotating block 210 are movably installed on one side of the positioning shaft 211, and the positioning shaft 211 is fixedly installed on one side of the rotating plate 201.

[0035] The clamping mechanism 2 also includes a first clamping block 21 and a second clamping block 22. The first clamping block 21 and the second clamping block 22 are symmetrically arranged with the slider 208 as the center. The first clamping block 21 and the second clamping block 22 both include a baffle 212, an arc-shaped limiting rod 213, a second spring 214 and a positioning clamp 215. The baffle 212 is fixedly installed on one side of the rotating plate 201. One side of the baffle 212 is fixedly connected to the arc-shaped limiting rod 213.

The arc-shaped limiting rod 213 is movably connected to the inside of the hole opened on the first rotating block 209 .

[0038] What needs to be further explained is that: when the capsule needs to be placed, the pressure plate 207 is manually pressed to drive the slider 208 to move downward inside the slide groove 205. At this time, the first spring 206 is compressed, and then the slider 208 pushes the first rotating block 209 and the second rotating block 210 to both sides, and further compresses the second spring 214. At this time, the first rotating block 209 and the second rotating block 210 drive the positioning clamp 215 to move to both sides at the same time. After the patient opens the rotating plate 201 to one side of the shell 1, aligns the capsule with the positioning clamp 215 and places it, releases the pressure plate 207. Under the action of the first spring 206 and the second spring 214, the pressure plate 207 and the positioning clamp 215 are reset to complete the clamping of the capsule.

[0039] like Figure 6 、 Figure 7 and Figure 8 As shown, the puncture mechanism 3 includes a knob 301, a rotating rod 302, a first limiting rod 303, a second limiting rod 304, a base 305, a worm 306, a worm gear 307 and an elliptical disk 308. The knob 301 is arranged on the outside of the shell 1, and one side of the knob 301 is fixedly connected to the rotating rod 302, and the rotating rod 302 is movably connected to one side of the base 305. One side of the base 305 is movably connected to the first limiting rod 303, and one side of the base 305 is also movably connected to the second limiting rod 304. One side of the rotating rod 302 is fixedly connected to the worm 306, and one side of the worm 306 is meshed with a worm gear 307, and the worm gear 307 is fixedly mounted on one side of the elliptical disk 308.

[0040] The puncture mechanism 3 also includes a first puncture device 31, a second puncture device 32, a positioning plate 317 and a deflector 318. The first puncture device 31 and the second puncture device 32 are symmetrically arranged with the worm gear 307 as the center. The first puncture device 31 and the second puncture device 32 each include a roller 309, a positioning rod 310, a limiting ring 311, a third spring 312, a limiting tube 313, a cross bar 314, a third limiting rod 315 and a puncture needle body 316. The roller 309 is movably connected to one side of the elliptical disk 308, and the roller 309 is movably mounted on one side of the positioning rod 310. The positioning rod 310 A limiting ring 311 is fixedly installed on the side close to the roller 309, and a third spring 312 is fixedly connected to one side of the limiting ring 311. The bottom of the third spring 312 is fixedly connected to a cross bar 314, and the cross bar 314 is movably connected to one side of the limiting tube 313. The limiting tube 313 is fixedly installed on one side of the base 305, and the third limiting rod 315 is movably installed on one side of the cross bar 314. The puncture needle body 316 is fixedly installed on the bottom of the cross bar 314, the positioning plate 317 is fixedly connected to the top of the base 305, and the bottom of the positioning plate 317 is fixedly installed with a deflector 318.

[0041] The puncture needle body 316 is set on the top of the positioning clamp 215, the deflector 318 is set on one side of the puncture needle body 316, the cross bar 314 is movably connected to one side of the third limiting rod 315, and the third limiting rod 315 is fixedly installed on one side of the base 305.

[0042] It needs to be further explained that: when it is necessary to puncture the capsule, the rotating rod 302 is rotated by manually turning the knob 301, which further drives the worm 306 and the worm gear 307 to engage and transmit, and then the elliptical disk 308 is rotated by the worm gear 307. At this time, when the elliptical disk 308 rotates to the longest vertical length, the rollers 309 and the positioning rods 310 on the first puncture device 31 and the second puncture device 32 are respectively pushed out in the upward and downward directions by the elliptical disk 308, and then the positioning rod 310 and the cross bar 314 move inside the limiting tube 313, further driving the puncture needle body 316 on one side of the cross bar 314 to puncture into the positioning clamp 215 inside the capsule, completing the puncture of the capsule; then continue to rotate the knob 301 to drive the elliptical disk 308 to rotate to the position where the upper and lower lengths are shortest. At this time, the puncture needle body 316 inside the first puncture device 31 and the second puncture device 32 is retracted to the initial position, and the knob 301 is manually pulled to drive the base 305 to move in the direction of the knob 301 as a whole, which can drive the puncture needle body 316 out of the top of the capsule. At the same time, the deflector 318 is driven to the top of the capsule inside the positioning clamp 215 as the base 305 moves, and is connected to the suction nozzle 6 and the capsule respectively. At this time, the patient can align his mouth with the suction nozzle 6 to inhale.

[0043] The working principle and use process of the utility model: During the use of the utility model, when the capsule breaking mechanism of a powder aerosol drug delivery device is used, first, the patient opens the dust cover 4;

[0044] Next, when the capsule needs to be placed, the pressing plate 207 is manually pressed to drive the slider 208 to move downward inside the slide groove 205. At this time, the first spring 206 is compressed, and then the slider 208 opens the first rotating block 209 and the second rotating block 210 to both sides, and further compresses the second spring 214. At this time, the first rotating block 209 and the second rotating block 210 drive the positioning clamp 215 to move to both sides at the same time. After the patient opens the rotating plate 201 to one side of the shell 1, aligns the capsule with the positioning clamp 215 and places it, releases the pressing plate 207. Under the action of the first spring 206 and the second spring 214, the pressing plate 207 and the positioning clamp 215 are reset to complete the clamping of the capsule.

[0045] Next, when it is necessary to puncture the capsule, the knob 301 is manually turned to drive the rotating rod 302 to rotate, further driving the worm 306 and the worm gear 307 to engage and transmit, and then the elliptical disk 308 is driven to rotate by the worm gear 307. At this time, when the elliptical disk 308 rotates to the longest vertical length, the rollers 309 and the positioning rods 310 on the first puncture device 31 and the second puncture device 32 are respectively pushed up and down by the elliptical disk 308, and then the positioning rod 310 and the cross bar 314 move inside the limiting tube 313, further driving the puncture needle body 316 on one side of the cross bar 314 to puncture. The needle enters the capsule inside the positioning clip 215 to complete the puncture of the capsule; then continue to rotate the knob 301 to drive the elliptical disk 308 to rotate to the position where the upper and lower lengths are shortest. At this time, the puncture needle body 316 inside the first puncture device 31 and the second puncture device 32 shrinks to the initial position, and the base 305 is driven as a whole toward the direction of the knob 301 by manually pulling the knob 301, which can drive the puncture needle body 316 to be separated from the top of the capsule. At the same time, the deflector 318 is driven to the top of the capsule inside the positioning clip 215 as the base 305 moves, and is connected to the suction nozzle 6 and the capsule respectively.

[0046] At this time, the patient can align his mouth with the suction nozzle 6 to inhale and receive treatment by sucking in the medicine powder.
