Description

Technical Field

[0001] The utility model relates to a medicinal quantitative aerosol driver, in particular to a medicinal inhalation aerosol driver which uses an electronic module to achieve counting. Background Art

[0002] Medicinal inhalation aerosol products have the requirement of stable dosage each time they are released. The most common technical means to achieve the effect of stable dosage is to use a quantitative aerosol driver. The nozzle part in the quantitative aerosol driver cooperates with the valve component installed at the mouth of the aerosol bottle, so that the fixed dose of liquid medicine in the aerosol bottle can be sprayed into the patient's mouth in the form of aerosol. The drug molecules in the aerosol finally act on the patient's lungs through the throat.

[0003] The counting driver not only ensures the accuracy and stability of each dose, but also displays the number of uses that the remaining liquid medicine in the aerosol bottle can provide to the patient, thus solving the problem that the patient cannot predict the amount of liquid medicine used, and is conducive to the patient to prepare a new quantitative aerosol driver or replace a new aerosol bottle in time.

[0004] However, most of the counting drivers on the market now use mechanical structure transmission, with many counting components and complex transmission coordination. When any component in the counting component is worn, it may cause transmission error, resulting in final counting errors. And when only the aerosol bottle is replaced, the complexity of the mechanical structure makes it difficult to reset the entire device. Utility Model Content

[0005] The main purpose of the utility model is to provide an electronic counting driver which is convenient for patients to confirm dosage information and subsequent use in view of the above problems.

[0006] An electronic counting driver comprises a driver housing, a counting module, an aerosol bottle, a counting outer cover and a nozzle cover, wherein:

[0007] The driver housing is provided with two openings, facing the vertical direction and the horizontal direction respectively. The opening facing the vertical direction is used to accommodate the aerosol bottle, and the opening facing the horizontal direction is a suction nozzle, which is an outlet for spraying aerosol into the patient's oral cavity during actual use;

DETAILED DESCRIPTION

[0032] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0033] Figures 1 to 6 A preferred embodiment of the electronic counting driver of the utility model is shown, which comprises: a driver housing 1, an aerosol bottle 2, a counting module 3, a counting outer cover 4, a nozzle cover 5 and other structural parts. Among them:

[0034] like Figure 1-2As shown, the driver housing 1 includes two openings facing the vertical and horizontal directions respectively. The opening facing the vertical direction is the opening position for accommodating the aerosol bottle 2. The aerosol bottle 2 is assembled into the driver housing 1 through the opening. The aerosol can is fixed by the plug-in valve rod 101. The plug-in valve rod 101 can convert the liquid state medicine originally flowing in the vertical direction into the aerosol state medicine sprayed in the horizontal direction; the opening facing the horizontal direction is the suction nozzle 103. In actual use, the patient puts the suction nozzle 103 into the oral cavity, whereby the aerosol state medicine can enter the patient's oral cavity, pass through the patient's throat, and finally directly act on the patient's lungs. An integrated transmission finger 102 is arranged on the driver housing 1 above the suction nozzle 103. The transmission finger 102 is a flexible structure, the upper end of which is fixedly connected to the driver housing 1, and the lower end can be bent and changed.

[0035] like Figure 3-5 As shown, the counting module 3 is provided with a plurality of through positioning holes 301, and a counting sensor 302 is provided on one side of the counting module 3. The counting sensor 302 adopts a self-reset button structure, and its arrangement position corresponds to the lower end of the transmission finger 102. The other side of the counting module 3 is arranged with components such as a display screen 303, a power switch 304, a reset switch 305, and a battery 306.

[0036] A positioning column 401 is provided at a position corresponding to the positioning hole 301 on the counting outer cover 4, so that the counting module 3 can be easily installed in place during the installation process to prevent the counting module 3 from being offset in the vertical direction. At the same time, the counting module 3 is clamped with a plurality of limiting columns 402 to prevent the counting module 3 from being offset in the horizontal direction, thereby ensuring the counting effectiveness of the device during the entire use cycle. A display window 403 is provided on the counting outer cover 4, through which the patient can observe the display screen 303, thereby obtaining information on the number of times the remaining liquid medicine in the device can be used.

[0037] A plurality of through holes can be observed on the outer surface of the counting outer cover 4. The holes correspond to the positions of the power switch 304 and the reset switch 305 respectively. The nozzle cover 5 includes a thimble 501. The patient can use the thimble 501 to simply control the power switch 304 and the reset switch 305 through the small hole to complete the power control and reset operation of the device, avoid unnecessary power loss, and extend the service life of the device. At the same time, a thimble storage hole 502 is provided inside the nozzle cover 4, which is convenient for the patient to store the thimble 501 during daily carrying.

[0038] like Figure 6As shown, the inner side of the lower end of the transmission finger 102 is a convex structure, which corresponds to the step depression near the bottle mouth of the aerosol bottle 2. The valve stem 201 on the aerosol bottle 2 is inserted into the plug valve stem 101 in the driver housing 1 and fixed. During the use of the patient, with the downward pressure of the aerosol bottle 2, the upper end of the step depression squeezes the convex structure at the lower end of the transmission finger 102, and the transmission finger 102 bends outward to touch the counting sensor 302, completing the counting of a single dose, and the value shown on the display screen 303 will be reduced by one accordingly. At the same time, the aerosol bottle 2 is pressed down, and the valve stem 201 operates to convert the internal liquid medicine in the aerosol bottle 2 into an aerosol form, and the liquid medicine in the aerosol form is ejected through the plug valve stem 101 in the horizontal direction through the suction nozzle 103. The counting sensor 302 adopts a self-resetting button. When the patient has finished using it, the aerosol bottle 2, the transmission finger 102 and the counting sensor 302 all return to the starting position without force, so that the patient can use it next time.
