Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a counting panel, a counting module and an inhalation device. Background Technology

[0002] Treating patients with medications contained in aerosols is well-known, for example, in the treatment of respiratory diseases. It is also known that medications for such treatment are contained in aerosols and administered to the patient via an inhalation device comprising a mouthpiece and a housing containing an aerosol canister. Such inhalation devices are commonly referred to as metered-dose inhalers (MDIs). The aerosol canister used in such inhalation devices is designed to deliver a predetermined dose of medication each time it is actuated by means of an outlet valve member (e.g., a metering slide valve) at one end, which can be opened by pressing down the valve member while the canister is stationary or by pressing down the canister while the valve member is stationary. When using such a device, the aerosol canister is placed in the housing, and the outlet valve member of the canister communicates with the mouthpiece. When used to dispense medication (e.g., in bronchodilator therapy), the patient holds the housing generally in an upright position and places the mouthpiece of the inhalation device in the patient's mouth, then actuates the aerosol canister to dispense a dose of medication from the canister, which is then inhaled by the patient.

[0003] To visualize the amount of medication remaining in such inhalation devices, many devices currently provide counters to display the dosage remaining in the aerosol canister. In the counter structure, the counting panel is a crucial component of the dosage indicator. Chinese patent CN1976735B discloses a counting panel (top surface + display arrangement) using double-shot molding; however, this counting panel requires sophisticated manufacturing processes and equipment, and incurs significant costs.

[0022] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0023] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0024] See Figures 1 to 3 As shown, this utility model provides a counting panel, which is mounted on a counter base 51 and includes a counting disk frame 521 and a counting disk 522. The counting disk 522 and the counting disk frame 521 are each independently formed and then welded together. Specifically, the counting disk frame 521 has a mounting opening, and the counting disk 522 is disposed within the mounting opening. The counting disk frame 521 and the counting disk 522 are independently formed molded components, and they can be integrated into a single structure by hot melting or ultrasonic welding.

[0025] Compared to the dual-injection molding process, the counting panel 52 of this application adopts a production process of split molding followed by welding, which has low equipment requirements and simple process, and can effectively reduce production costs.

[0026] In some embodiments, a foolproof element 5211 is provided in the mounting port, and a foolproof groove 5221 corresponding to the foolproof element 5211 is provided on the counting disk 522. The counting disk frame 521 and the counting disk 522 can be positioned by the foolproof element 5211 and the foolproof groove 5221, thereby ensuring the accurate position of the static display part 5223 on the counting disk 522 and facilitating subsequent welding operations.

[0027] Mistake-proof components and slots include, but are not limited to, trapezoidal structures, such as rectangles, triangles, etc.

[0028] Furthermore, the edge cross-section of the mounting port and the edge cross-section of the counting disk 522 are complementary stepped structures, which facilitates the assembly of the counting disk frame 521 and the counting disk 522.

[0029] Furthermore, the counting disk 522 is provided with energy guiding ribs 5222 along its own contour, and the counting disk frame 521 and the counting disk 522 are fixed by ultrasonic welding. Among them, the energy guiding ribs 5222 are small triangular structures, which can enhance energy transfer and improve the welding strength of the counting disk frame 521 and the counting disk 522.

[0030] In some embodiments, the counting disk frame 521 is provided with a plurality of transverse protrusions 5212 spaced apart around the periphery, and the counter base 51 is provided with a plurality of transverse slots 5121 that correspond to the transverse protrusions 5212 around the periphery, so that the counting panel 52 can be quickly snapped and fixed to the counter base 51 for easy assembly.

[0031] Furthermore, a vertical protrusion 5213 is provided below some of the horizontal protrusions 5212, and the counter base 51 is provided with multiple vertical slots 5122 that correspond to the vertical protrusions 5213 in the circumferential direction to limit the degree of freedom of the counting panel 52 in the circumferential direction and further improve its stability after installation.

[0032] Furthermore, the counting disk frame 521 and the counter base 51 are snapped together and then welded into a single structure. By snapping together and then welding, the welding process is facilitated, while the connection strength between the counting panel 52 and the counter base 51 is enhanced, ensuring that the static display part 5223 on the counting panel 52 will not move, thus guaranteeing the accuracy of the counting results.

[0033] In some embodiments, the counting disk 522 is provided with a static display portion 5223, such as circumferentially arranged numerical scales, and at least the area inside the static display portion 5223 is made of a transparent material so that the static display portion 5223 can form a visible engagement with the movable display portion (not shown) of the indicator disk.

[0034] This utility model also discloses a counting module, including the aforementioned counting panel.

[0035] See Figure 4 As shown, this utility model also discloses an inhalation device, including the counting module described above.
