Description

Technical Field

[0001] This invention relates to the field of torque testing technology, and more specifically to a device for testing the torque when the nozzle cover of an Ellipta device is opened and closed. Background Technology

[0002] Dry powder inhalers are widely used to treat respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD), offering advantages such as rapid onset of action, few side effects, and no first-pass effect. Bubble-type dry powder inhalers consist of a micro-filling of a pre-mixed powder into a cold-formed hard aluminum (base foil) blister, which is then covered and heat-sealed with paper aluminum (cover foil) to form a sealed aluminum foil blister strip. This blister strip is coiled and inserted into a dry powder inhaler. The base foil and cover foil are heat-pressed to form an aluminum foil blister strip. The front end of the aluminum foil blister strip is not heat-sealed to form a fork. The front end of the cover foil needs to be bent 360° along the aluminum side and heat-sealed to form an aluminum foil ring. When the aluminum foil blister strip is coiled and inserted into the inhalation device, it is installed on the pin of the torsion wheel. The front end of the base foil is bent 90° to form a 1.5-3.5mm long bend. When the aluminum foil blister strip is coiled and inserted into the inhalation device, it is installed in the fork of the roll. When the patient uses the inhaled preparation, by turning the mouthpiece cover of the inhalation device, the internal torsion wheel and roll gear system are driven to move, tearing open the heat-sealed aluminum foil blister strip and exposing the powder in the mouthpiece for the patient to inhale.

[0003] The Ellipta device, a new generation of blister-type dry powder inhaler, is used by patients with asthma and COPD. When these patients experience an attack, they urgently need fast-acting medication to relieve symptoms as quickly as possible, and dry powder inhalers can meet this requirement. However, due to the limited mobility of asthma and COPD patients, if the aluminum foil blister strip is too tightly heat-sealed or the internal gear components are not installed correctly, the mouthpiece cap may open and close with excessive force. Conversely, if the aluminum foil blister strip is not properly installed during winding and insertion into the Ellipta device, such as incorrect foil rings and bends, the aluminum foil strip may not be able to be torn open when the mouthpiece cap is moved, exposing the medication. This results in insufficient opening and closing force for the mouthpiece cap. Both of these situations can prevent patients from receiving timely medication, endangering their lives. Therefore, during the assembly process of the inhaled formulation, after the device components and aluminum foil blister strip are assembled, it is necessary to sample and test the torque value of the mouthpiece cap opening and closing process to determine whether the device assembly is qualified. Generally, the torque value of the mouthpiece cap opening and closing is 0.1–0.6 N·m.

[0004] In the existing technology, there are many types of torque testing equipment, but there is no equipment specifically for testing the torque when the nozzle cover of the Ellipta device is opened and closed. Based on this, an equipment for testing the torque when the nozzle cover of the Ellipta device is opened and closed is provided. Summary of the Invention

[0005] This invention addresses the technical problem of the lack of dedicated equipment for testing the torque of the Ellipta device's nozzle cap during opening and closing. The aim is to provide a device for testing the torque of the Ellipta device's nozzle cap during opening and closing. This device has a simple structure, is easy to operate, and can test the torque of the nozzle cap opening and closing. Based on the test data, it can evaluate the heat sealing degree of the aluminum foil blister strip, whether the components within the device are correctly assembled and functioning well, and thus assess whether the product meets quality standards. This provides a basis for process control in pharmaceutical manufacturing and for judging product quality.

[0006] The present invention is achieved through the following technical solution.

[0007] An apparatus for testing the torque during the opening and closing of the nozzle cap of an Ellipta device, comprising:

[0008] Base;

[0009] The upper clamp is used to hold the nozzle cover of the Ellipta device;

[0010] The lower clamp is connected to the base shaft at its bottom. The lower clamp is equipped with a limiting structure for fixing the housing of the Ellipta device. The lower clamp is used to drive the housing of the Ellipta device to rotate relative to the nozzle cover.

[0011] Torque sensor, connected to the top of the upper clamp;

[0012] The lifting drive mechanism is used to drive the torque sensor to adjust the height up and down;

[0013] The vacuuming mechanism is used to vacuum remove drug dust from the nozzle opening after the housing of the Ellipta device rotates relative to the nozzle cover to expose the nozzle opening.

[0014] In the torque test of the nozzle cover opening and closing process, the Ellipta device is first placed in the lower clamp, and the housing is fixed by the limiting structure. The lifting drive mechanism is adjusted so that the height of the torque sensor and the upper clamp is lowered to a suitable position, so that the upper clamp can just hold both sides of the nozzle cover. At this time, the position of the upper clamp is 0.0 deg (0.0°). The ambient temperature is controlled at 23℃±2℃ and the relative humidity is 50%±5%. The opening speed V1 (range: 0~3600 deg / min) and closing speed V2 (range: 0~3600 deg / min) of the rotating shaft are set. (0~3600 deg / min) Turn on the equipment, causing the lower clamp to rotate the Ellipta device housing counterclockwise. The upper clamp holds the two sides of the nozzle cover stationary. At this time, the Ellipta device housing and the nozzle cover rotate relative to each other, thus opening the nozzle cover and exposing the nozzle opening. The suction mechanism aims at the nozzle opening and sucks away the exposed powder, preventing active dust from escaping into the environment and affecting personnel. After suction is complete, the lower clamp rotates the fixed housing of the Ellipta device clockwise, closing the nozzle cover to complete the torque test. During the opening and closing of the nozzle cover, the torque sensor captures the torsional force and converts the physical change into an electrical signal, thereby accurately obtaining the torque value when the nozzle cover opens and closes. The maximum, minimum, average, and standard deviation of the torque are displayed on the HMI. Based on these data, the heat sealing (tear-off) degree of the aluminum foil blister strip and whether the components inside the device are correctly assembled and functioning well can be evaluated, thus assessing whether the product meets quality standards.

[0015] This invention provides a device specifically for testing the torque of the Ellipta device's nozzle cap during opening and closing. It uses upper and lower clamps to secure the Ellipta device's nozzle cap and housing, facilitating easy opening and closing of the nozzle cap. A lifting drive mechanism allows for height adjustment of the upper clamp to accurately hold the nozzle cap. A dust extraction mechanism quickly removes drug dust, preventing operators from prolonged exposure to highly active drug dust and its potential health risks. The entire device is simple in structure, easy to operate, and suitable for testing the opening and closing torque of the Ellipta device's nozzle cap. It provides a basis for controlling the formulation production process, judging product quality, ensuring product quality throughout its entire lifecycle, and guaranteeing timely and safe medication for patients.

[0016] Furthermore, the upper clamp is fixed to the mounting base. The upper clamp includes a connecting rod and clamping rods. One end of the connecting rod is fixedly connected to the mounting base, and the other end is provided with two clamping rods for clamping both sides of the nozzle cover of the Ellipta device. Specifically, the upper clamp is mounted on the square driver of the torque sensor. The upper clamp is coaxial with the torque sensor. The connecting rod passes through a dedicated fixing hole inside the upper clamp. Screw holes are provided on the side of the upper clamp to facilitate fixing the connecting rod with screws. The two clamping rods at the ends are spaced apart, and this distance matches the width between the two sides of the nozzle cover to achieve clamping of both sides of the nozzle cover.

[0017] Furthermore, the lower clamp includes a chassis, a limiting structure, and a stepped surface. The stepped surface protrudes from the chassis surface and is adapted to the shape of the Ellipta device's housing to support the housing. The limiting structure is located on the stepped surface to fix the housing of the Ellipta device. Specifically, the stepped surface creates a gap between the bottom of the nozzle cap and the chassis, ensuring that the bottom of the nozzle cap has room to slide. The limiting structure serves to fix the housing of the Ellipta device placed on the stepped surface, preventing the housing from shifting during the rotation of the lower clamp.

[0018] Furthermore, the chassis has multiple fixing holes in the middle for connection with the rotating shaft to achieve rotation. Specifically, the chassis, as the component connecting the lower clamp to the rotating shaft, has fixing holes on it for easy fixing to the rotating shaft. The machine base is equipped with a drive source such as a motor and a reducer. The output end of the drive source is connected to the rotating shaft, thereby transmitting rotational power to the chassis, causing the lower clamp to rotate.

[0019] Furthermore, the limiting structure includes a limiting post and a lever. The limiting post is located at the edge of the stepped surface, and the lever is detachably mounted on the limiting post. The bottom of the lever has a hook for embedding into the gap between the housing and the nozzle cover of the Ellipta device. Specifically, the stepped surface has three corners, each with a limiting post. The inner surface of the limiting post is arc-shaped to fit the external shape of the Ellipta device. The lever is mounted on one of the limiting posts using fasteners such as screws. In use, the hook at the bottom of the lever is engaged in the gap between the nozzle cover and the housing, hooking onto the edge of the housing. The lever is then tightened, and the housing of the Ellipta device is fixed to the lower clamp.

[0020] Furthermore, the lifting drive mechanism includes a lifting drive motor and a lifting lead screw. The torque sensor is connected to the lifting lead screw. The lifting drive motor drives the torque sensor and the upper clamp to move up and down along the length of the lifting lead screw. Therefore, the lifting drive mechanism realizes the position adjustment of the upper clamp in the height direction, thereby facilitating the accurate clamping of the nozzle cover.

[0021] Furthermore, a dust collection tray is installed between the lower clamp and the base to collect dust that falls off during the testing process but is not completely removed by the dust collection mechanism. Specifically, a through hole is provided in the middle of the dust collection tray to facilitate the passage of the rotating shaft. The dust collection tray does not rotate with the rotating shaft and its size is larger than the size of the base of the lower clamp to facilitate efficient dust collection.

[0022] Furthermore, the vacuuming mechanism includes a vacuuming device, a rigid suction tube for medicinal powder, a flexible tube, and a servo motor. The rigid suction tube for medicinal powder is connected to the vacuuming interface of the vacuuming mechanism. The tail end of the rigid suction tube for medicinal powder is fixed to the output end of the servo motor, and a flexible tube is connected to the rigid suction tube for medicinal powder near the servo motor. The flexible tube connected to the rigid suction tube for medicinal powder near the servo motor allows for lateral movement when the servo motor drives the front end of the rigid suction tube to align with the suction nozzle. In use, when the suction nozzle cover is opened to expose the suction nozzle, the medicinal powder is also exposed at the bottom of the suction nozzle. Since the medicinal powder is generally highly active and contains hormones, prolonged exposure can affect the operator's health. Therefore, a vacuuming mechanism is added. The servo motor adjusts the vacuuming device's suction port to automatically align with the suction nozzle, and then quickly sucks away the exposed medicinal powder.

[0023] Furthermore, the dust collection device includes a dust collection bag, an H14 high-efficiency filter, a vacuum fan, and a vacuum motor. The dust collection bag is installed below the high-efficiency filter. The vacuum motor drives the vacuum fan to rotate, creating an air pressure difference to adsorb the powder. The air containing the powder is filtered by the H14 high-efficiency filter and then discharged cleanly from the exhaust port. The dust collection bag collects the dust trapped by the H14 high-efficiency filter. The vacuum motor drives the vacuum fan to rotate, creating an internal vacuum to adsorb the dust through an air pressure difference. The air containing the powder is then filtered by the H14 high-efficiency filter and discharged as purified air.

[0024] Furthermore, it also includes an HMI and an audible and visual alarm. The display screen is electrically connected to the torque sensor for user login / logout, displaying the torque value detected by the torque sensor, the torque value curve, and setting related parameters and exporting reports. The audible and visual alarm is used to issue an audible and visual alarm when the torque sensor detects an abnormal torque value, the emergency stop button is pressed, or the equipment malfunctions.

[0025] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0026] This invention provides a device specifically for testing the torque of the Ellipta device's nozzle cap during opening and closing. It uses upper and lower clamps to secure the Ellipta device's nozzle cap and housing, facilitating easy opening and closing of the nozzle cap. A lifting drive mechanism allows for height adjustment of the upper clamp to accurately hold the nozzle cap. A dust extraction mechanism quickly removes drug dust, preventing operators from prolonged exposure to highly active drug dust and its potential health risks. The entire device is simple in structure, easy to operate, and suitable for testing the opening and closing torque of the Ellipta device's nozzle cap. It provides a basis for controlling the formulation production process, judging product quality, ensuring product quality throughout its entire lifecycle, and guaranteeing timely and safe medication for patients.

[0041] Example 1

[0042] A device for testing the torque during the opening and closing of the nozzle cap 103 of the Ellipta device 10, such as Figure 1-6 As shown, it includes:

[0043] Base 9;

[0044] The upper clamp 6 is used to clamp the nozzle cover 103 of the Ellipta device 10;

[0045] The lower clamp 7 is rotatably connected to the base 9 at its bottom. The lower clamp 7 is provided with a limiting structure for fixing the housing 101 of the Ellipta device 10. The lower clamp 7 is used to drive the housing 101 of the Ellipta device 10 to rotate relative to the nozzle cover 103.

[0046] Torque sensor 3 is connected to the top of upper clamp 6;

[0047] The lifting drive mechanism is used to drive the torque sensor 3 to adjust the height up and down;

[0048] The vacuuming mechanism is used to vacuum remove drug dust from the nozzle opening after the housing 101 of the Ellipta device 10 rotates relative to the nozzle cover 103 to expose the nozzle opening.

[0049] In the torque test of the opening and closing process of the nozzle cover 103, the Ellipta device 10 is first placed in the lower clamp 7, and the housing 101 is partially fixed by the limiting structure. The lifting drive mechanism is adjusted so that the height of the torque sensor 3 and the upper clamp 6 is lowered to a suitable position, so that the upper clamp 6 can just hold the two sides of the nozzle cover 103. At this time, the position of the upper clamp is 0.0 deg (0.0°). The ambient temperature is controlled at 23℃±2℃ and the relative humidity is 50%±5%. The opening speed V1 (range: 0~3600 deg / min) and closing speed V2 (range: 0~3600 deg / min) of the rotating shaft are set. The device is turned on, so that the lower clamp 7 drives the housing 101 of the Ellipta device 10 to rotate. The upper clamp 6 holds the two sides of the nozzle cover 103 still. At this time, the Ellipta device... The housing 101 of the Ellipta device 10 rotates counterclockwise with the nozzle cover 103, thereby opening the nozzle cover 103 and exposing the nozzle opening. The vacuuming mechanism is aligned with the nozzle opening to suck away the exposed powder, preventing the active powder from escaping into the environment and affecting personnel. After vacuuming, the lower clamp 7 drives the fixed housing 101 of the Ellipta device 10 to rotate clockwise, causing the nozzle cover 103 to close and complete the torque test. During the opening and closing of the nozzle cover 103, the torque sensor 3 captures the torsional force and converts the physical change into an electrical signal, thereby accurately obtaining the torque value when the nozzle cover 103 is opened and closed, and displaying the maximum, minimum, average, and standard deviation of the torque on the HMI12. Based on these data, the heat sealing (tear-resistant) degree of the aluminum foil blister strip and whether the components inside the device are correctly assembled and functioning well can be evaluated, thereby assessing whether the product meets the quality standards.

[0050] This invention provides a device specifically for testing the torque of the Ellipta device 10 nozzle cap 103 during opening and closing. The device uses an upper clamp 6 and a lower clamp 7 to fix the nozzle cap 103 and the housing 101 of the Ellipta device 10, facilitating the opening and closing of the nozzle cap 103. A lifting drive mechanism allows for height adjustment of the upper clamp 6 to accurately hold the nozzle cap 103. A dust extraction mechanism quickly removes drug dust, preventing operators from prolonged exposure to highly active drug dust and its potential health risks. The entire device has a simple structure and is easy to operate. It is suitable for testing the opening and closing torque of the Ellipta device 10 nozzle cap 103, providing a basis for controlling the formulation production process, judging product quality, ensuring product quality throughout its entire lifecycle, and guaranteeing timely and safe medication for patients.

[0051] The device of the present invention also includes an HMI 12 and an audible and visual alarm 13. The HMI 12 is electrically connected to the torque sensor 3 for user login / logout, displaying the torque value detected by the torque sensor, the torque value curve, and setting related parameters and exporting reports. The audible and visual alarm 13 is used to issue an audible and visual alarm when the torque sensor detects an abnormal torque value, the emergency stop button is pressed, or the equipment malfunctions. Various function buttons are also provided on the base 9 to facilitate the operation of related structures and can be set as needed. Since this is prior art, it will not be described in detail here.

[0052] The Ellipta device 10 described in this invention is prior art; its specific internal structure and working principle are also prior art. To facilitate understanding of the technical solution of this invention, a brief description of the component composition of the Ellipta device 10 involved in this invention is provided below. (See attached text.) Figure 4 The device includes a housing 101, a sliding space 102, a nozzle cover 103, and a gap 104 between the housing 101 and the nozzle cover 103. The housing 101 is a fixed part that cannot move. The nozzle cover 103 can slide along the sliding space 102 to open and close the nozzle opening. The gap 104 between the housing 101 and the nozzle cover 103 is to facilitate the locking structure of the lower clamp 7 to fix the housing 101.

[0053] See Figure 6 The upper clamp 6 is fixed on the mounting base 5. The upper clamp 6 includes a connecting rod 601 and clamping rods 602. One end of the connecting rod 601 is fixedly connected to the mounting base 5, and the other end is provided with two clamping rods 602. The two clamping rods 602 are used to clamp the two sides of the nozzle cover 103 of the Ellipta device 10. Specifically, the upper clamp 6 is installed on the square driver of the torque sensor 3. The upper clamp 6 is coaxial with the torque sensor 3. The connecting rod 601 passes through the dedicated fixing hole 706 inside the upper clamp 6. The upper clamp 6 has screw holes on its side to facilitate fixing the connecting rod 601 with screws. The two clamping rods 602 at the end are spaced apart. This distance matches the width between the two sides of the nozzle cover 103 to achieve clamping of the two sides of the nozzle cover 103.

[0054] See Figure 3 and 5The lower clamp 7 includes a base 701, a limiting structure, and a stepped surface 705. The stepped surface 705 protrudes from the surface of the base 701 and is adapted to the shape of the Ellipta device housing to support the housing 101 of the Ellipta device 10. The limiting structure is provided on the stepped surface 705 to fix the housing 101 of the Ellipta device 10. Specifically, the step surface 705 provides a certain gap 104 between the bottom of the nozzle cover 103 and the base 701. This gap 104 ensures that the bottom of the nozzle cover 103 has room to slide. The limiting structure serves to fix the housing 101 of the Ellipta device 10 placed on the stepped surface 705, preventing the fixed housing 101 of the Ellipta device 10 from shifting during the rotation of the lower clamp 7.

[0055] See Figure 3 The chassis 701 has multiple fixing holes 706 in the middle for connecting with the rotating shaft 11 to achieve rotation. Specifically, the chassis 701 serves as the component connecting the lower clamp 7 to the rotating shaft 11. The fixing holes 706 on the chassis facilitate a fixed connection with the rotating shaft 11. The base 9 is equipped with a drive source such as a motor and a reducer. The output end of the drive source is connected to the rotating shaft 11, thereby transmitting rotational power to the chassis 701, causing the lower clamp 7 to rotate.

[0056] In one specific implementation, see Figure 3 The limiting structure includes a limiting post 702 and a lever 703. The limiting post 702 is located at the edge of the stepped surface 705, and the lever 703 is detachably mounted on the limiting post 702. The bottom of the lever 703 has a hook 704 for embedding into the gap 104 between the fixed housing 101 and the nozzle cover 103 of the Ellipta device 10. Specifically, the stepped surface 705 has three corners, each corner having a limiting post 702. The inner surface of the limiting post 702 is arc-shaped to fit the external shape of the Ellipta device 10. The lever 703 is mounted on one of the limiting posts 702 using fasteners such as screws. In use, the hook 704 at the bottom of the lever 703 is engaged in the gap 104 between the nozzle cover 103 and the fixed housing 101, hooking onto the edge of the fixed housing 101. The lever 703 is then tightened, and the housing 101 of the Ellipta device 10 is fixed on the lower clamp 7.

[0057] See Figure 1 The lifting drive mechanism includes a lifting drive motor 1 and a lifting lead screw 2. The torque sensor 3 is connected to the lifting lead screw 2. The lifting drive motor 1 drives the torque sensor 3 and the upper clamp 6 to move up and down along the length of the lifting lead screw 2. Therefore, the lifting drive mechanism realizes the position adjustment of the upper clamp 6 in the height direction, which facilitates the accurate clamping of both sides of the nozzle cover 103.

[0058] See Figure 1 and Figure 2 A dust collection tray 8 is also installed between the lower clamp 7 and the base 9 to collect dust that falls off during the test but is not completely removed by the vacuum. Specifically, the dust collection tray 8 has a through hole in the middle to facilitate the passage of the rotating shaft 11. The dust collection tray 8 does not rotate with the rotating shaft 11 and its size is larger than the size of the base of the lower clamp 7 in order to achieve efficient dust collection.

[0059] See Figure 1 The vacuuming mechanism includes a vacuuming device 17, a rigid suction tube 14 for medicinal powder, a flexible tube 15, and a servo motor 16. The rigid suction tube 14 for medicinal powder is connected to the vacuuming interface of the vacuuming mechanism. The tail of the rigid suction tube 14 is fixed to the output end of the servo motor 16, and the rigid suction tube 14 for medicinal powder is connected to the flexible tube 15 near the servo motor 16. The flexible tube 15 is connected to the rigid suction tube 14 for medicinal powder near the servo motor 16 to allow for lateral movement when the servo motor 16 drives the front end of the rigid suction tube 14 to align with the suction nozzle. In use, when the suction nozzle cover 103 is opened to expose the suction nozzle, the medicinal powder is also exposed at the bottom of the suction nozzle. Since the medicinal powder is generally highly active and contains hormones, prolonged exposure can affect the operator's health. Therefore, a vacuuming mechanism is added. The servo motor 16 adjusts the vacuuming port of the vacuuming device 17 to automatically align with the suction nozzle, and then quickly sucks away the exposed medicinal powder.

[0060] In one specific embodiment, the vacuuming device 17 includes a dust collection bag 171, an H14 high-efficiency filter 172, a vacuum fan 173, and a vacuum motor 174. The dust collection bag 171 is installed below the H14 high-efficiency filter 172. The vacuum motor 174 drives the vacuum fan 173 to rotate, creating an air pressure difference to adsorb the powder. The air containing the powder is filtered by the H14 high-efficiency filter 172 and then discharged cleanly from the exhaust port 175. The dust collection bag 171 collects the dust intercepted by the H14 high-efficiency filter 172. The vacuum motor 174 drives the vacuum fan 173 to rotate, creating an air pressure difference through an internal vacuum to adsorb the dust. The air containing the powder is filtered by the H14 high-efficiency filter 172 and then discharged as purified air.

[0061] Finally, it should be noted that the above specific embodiments are only used to describe the purpose, technical solution, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation of the present invention and is not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the foregoing specific embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions or improvements can be made to some or all of the technical features. These modifications, equivalent substitutions, and improvements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
