Description

Technical Field

[0001] The present invention relates to the technical field of detection of press - ejection type preparation products, and particularly relates to a device and a working method for detecting the number of presses of a press - ejection type preparation product. Background Art

[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Currently, it is necessary to detect the total number of presses for press - ejection type preparation products. For example, for metered - dose inhalers or nasal sprays, etc., it is necessary to detect the total number of presses. Pressing refers to the vertical pressing action on the bottom of the press - ejection type preparation product bottle and the actuator. In traditional detection methods, it is necessary to manually press the product multiple times. When all the drugs are completely ejected, the number of manual presses is the total number of presses for a bottle of product. However, due to differences among testers, it is impossible to ensure that the pressing force and stroke are the same each time, resulting in slightly different amounts of product ejected each time, and further causing inaccurate detection of the total number of presses for a bottle of product. Moreover, the tester manually presses multiple times, with high labor intensity and low detection efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a device and a working method for detecting the number of presses of a press - ejection type preparation product, which can ensure that the pressing force and stroke are the same each time and guarantee the accuracy of the detection of the number of presses.

[0005] To achieve the above - mentioned purpose, the present invention is realized through the following technical solutions:

[0006] In a first aspect, an embodiment of the present invention provides a device for detecting the number of presses of a press - ejection type preparation product, including a fixture.

The position of the pressing medicine cylinder corresponds to the position of the placement groove. A pressing block is provided at the end of the piston rod. The piston rod can press the aerosol product in the placement groove through the pressing block.

[0012] Optionally, the pressing medicine cylinder is equipped with a stroke detection element to detect the stroke of the piston rod of the pressing medicine cylinder.

[0013] Optionally, a medicine detection element fixed on the fixture is installed at the medicine ejection port to detect whether medicine is ejected from the medicine ejection port.

[0014] Optionally, the medicine detection element is a photoelectric sensor. The emitting end of the photoelectric sensor is fixed on one side of the medicine ejection port, and the receiving end of the photoelectric sensor is fixed on the other side of the medicine ejection port.

[0016] Optionally, the collection tank is also connected to one end of an exhaust pipe, the other end of the exhaust pipe is connected to a filtering device, and a valve and a blower are provided on the exhaust pipe. The blower is used to pump the gas in the collection tank into the filtering device.

[0017] In a second aspect, an embodiment of the present invention provides a working method for a pressing and ejecting type preparation product pressing times detection device, including the following steps:

[0018] The placement groove of the fixture accommodates the pressing and ejecting type preparation product to be detected, and the medicine ejection port of the pressing and ejecting type preparation product is aligned with the medicine ejection port on the fixture.

[0019] The downward pressing driving member works to press the pressing and ejecting type preparation product until all the medicine in the pressing and ejecting type preparation product to be detected is ejected, and record the pressing times of the downward pressing driving member on the pressing and ejecting type preparation product.

[0031] In this implementation mode, the pressing and ejecting preparation product includes an aerosol product or a spray product, etc.

[0032] Example 1

[0033] This example provides a device for detecting the number of presses of a pressing and ejecting preparation product, which is used for detecting the number of presses of an aerosol product, especially a suspension aerosol product. As Figures 1 - 3 shown, it includes a clamp 1, and the clamp 1 is used to fix the aerosol product 2 to be detected. The clamp 1 is provided with at least one placement groove 3, and the placement groove 3 is used to place the aerosol product 2 to be detected. In order to realize the simultaneous detection of multiple aerosol products 2 and improve the detection efficiency, the clamp 1 is provided with multiple placement grooves 3. Preferably, six placement grooves 3 are provided, which can simultaneously detect the total number of presses of six aerosol products 2. The clamp 1 is connected to a rotation driving part fixed on the housing 4, and the rotation driving part can drive the clamp 1 to rotate within a set angle range, so as to swing the aerosol product through the clamp 1 and shake the medicine in the aerosol product 2. In this example, one end or both ends of the clamp are connected to the rotation driving part. Preferably, one end of the clamp 1 is connected to the rotation driving part. A downward pressing driving part is arranged above the clamp 1, and the position of the downward pressing driving part corresponds to the position of the placement groove 3. Since six placement grooves 3 are provided, six downward pressing driving parts are provided, and the downward pressing driving parts correspond to the placement grooves 3 one by one. The downward pressing driving parts are fixed on the housing 4 and can output a downward pressing movement, so as to press the aerosol product 2 in the placement groove 3.

[0034] In this example, the shape of the placement groove 3 opened on the clamp matches the shape of the cover of the aerosol product 2. The clamp 1 is provided with multiple drug ejection ports 5, and each placement groove 3 corresponds to a drug ejection port 5. The drug ejection port 5 is communicated with the internal space of the placement groove 3. The setting position of the drug ejection port 5 is such that when the aerosol product 2 is placed in the placement groove 3, the drug ejection port 5 is aligned with the medicine spraying port of the aerosol product 2, and the medicine in the aerosol product 2 can be ejected through the medicine spraying port and the drug ejection port 5.

[0035] In one implementation mode, the cover of the aerosol product 2 is a columnar structure, and at this time, the placement groove 3 adopts a columnar groove matching the cover.

[0036] In another embodiment, the housing of the aerosol product 2 is bent at the spraying orifice to form an L-shaped housing. At this time, the placement groove 3 is an L-shaped groove matching the housing, including a first groove portion arranged vertically and a second groove portion arranged horizontally. The second groove portion is used to accommodate the bent portion of the housing at the spraying orifice. A push plate is provided at the bottom end of the first groove portion, and the push plate is connected to the groove surface of the first groove portion through a spring. When placing the aerosol product 2, first place the housing of the aerosol product 2 into the first groove portion. After the push plate contacts the housing, use the thrust of the spring to push the bent portion of the housing into the second groove portion. The housing and the groove surface of the first groove portion are tightly fixed by the elastic force of the spring. In this way, it is convenient to place the aerosol product in the placement groove and ensure the firmness of the aerosol product fixed in the placement groove, which is convenient for the subsequent alignment of the pressing drive member and the aerosol product.

[0037] Both ends of the fixture 1 are connected with fixing disks 6, and the fixing disk 6 on at least one side is connected with a rotation drive member. In this embodiment, in order to reduce the cost of the device, the fixing disk 6 on one side is connected with the rotation drive member, and the fixing disk 6 on the other side is rotatably connected with the housing 4.

[0038] Specifically, a circular groove matching the fixing disk 6 is formed on the housing, and the fixing disk 6 is embedded in the circular groove and the peripheral surface of the fixing disk 6 is slidably connected with the side groove surface of the circular groove.

[0039] In some other embodiments, the fixing disk 6 can also be rotatably connected with the housing through a rotating shaft, and those skilled in the art can set it according to actual needs.

[0040] In this embodiment, the rotation drive member is a servo motor, and the output shaft of the servo motor is connected with the fixing disk 6 through a coupling, which can drive the fixing disk 6 to rotate.

[0041] It can be understood that the rotation drive member can also be other devices capable of outputting rotational motion, such as a hydraulic motor or a stepper motor, etc. Those skilled in the art can select according to actual needs and will not be described in detail here.

[0042] As Figure 4 shown, a slot 7 is formed on the disk surface of the fixing disk 6 for connecting the fixture. Correspondingly, an insertion plate 8 is provided at the end of the fixture 1, and the insertion plate 8 is embedded in the slot 7. The insertion plate 8 is fixedly connected with the fixing disk 6 through a fixing member to realize the fixed connection between the fixture 1 and the fixing disk 6.

[0043] In this embodiment, the fixing member is an existing spring fixing pin 9. Existing components can be used, and its specific structure will not be described in detail here.

[0044] It can be understood that the fixing member can also be a bolt or a screw or other fixing members, and those skilled in the art can select according to actual needs.

[0045] The fixture is fixed to the fixed disk 6 through the spring fixing pin 9, which facilitates the disassembly of the fixture 1 for testing aerosol products of different specifications.

[0046] Above the fixture 1, there is a downward pressing driving member, which corresponds to the placement groove 3 on the fixture. In this embodiment, six downward pressing driving members are provided, corresponding to the six placement grooves 3 one by one.

[0047] The downward pressing driving member adopts a medicine pressing cylinder 10. The axis of the medicine pressing cylinder 10 is vertically arranged. The cylinder body of the medicine pressing cylinder 10 is fixed on the housing 4, and the end of its piston rod is connected with a pressing block. The piston rod of the medicine pressing cylinder 10 can apply pressure to the aerosol product 2 through the pressing block to press the aerosol product 2.

[0048] It can be understood that the downward pressing driving member can also adopt an electric telescopic rod or a hydraulic cylinder with a vertically arranged axis, as long as it can output a vertical linear motion, and no detailed description will be given here.

[0049] Furthermore, the medicine pressing cylinder 10 is equipped with a stroke detection element for detecting the stroke of the piston rod of the medicine pressing cylinder 10. The stroke detection element adopts a magnetic switch. The magnetic switch can use existing equipment, and its connection method with the medicine pressing cylinder 10 can also adopt existing technology, and no detailed description will be given here.

[0050] In some other embodiments, the medicine pressing cylinder 10 can also be arranged on the horizontal side of the fixture. When the aerosol product rotates to the horizontal state, the medicine pressing cylinder 10 applies pressure to the aerosol product. It can be understood that the position and angle of the medicine pressing cylinder 10 can be set according to actual needs, and no detailed description will be given here.

[0051] In this embodiment, the medicine pressing cylinder 10 is fixed on the housing, which facilitates the movement of the medicine pressing cylinder with the whole device. During multiple tests, there is no need to reposition the medicine pressing cylinder 10. In some other embodiments, the medicine pressing cylinder 10 can also be provided with an additional cylinder bracket, which can be set by those skilled in the art according to actual needs, and no detailed description will be given here.

[0052] In traditional detection methods, manual visual judgment is used to determine whether the medicine in the aerosol product is completely ejected, which is prone to misjudgment and inaccurate detection results. Therefore, in this embodiment, a medicine detection element is installed at the medicine ejection port to detect whether there is medicine ejection.

[0053] In this embodiment, the drug detection element uses an existing optoelectronic sensor, which has a transmitting end and a receiving end. Both the transmitting end and the receiving end are fixed on the surface of the fixture. The transmitting end is arranged on one side of the drug ejection port, and the receiving end is arranged on the other side of the drug ejection port. When the drug is ejected, it will affect the intensity of the ray emitted by the transmitting end received by the receiving end, so as to determine whether there is drug ejection from the drug ejection port.

[0054] In another embodiment, the drug detection element uses a pressure sensor arranged opposite to the drug ejection port. The pressure sensor is connected to a sensor bracket, and the sensor bracket is fixed on the fixture. When there is drug ejection, the increased value of the pressure detected by the pressure sensor will exceed the set threshold, so as to determine that there is drug ejection. When there is no drug ejection, the increased value of the pressure of the pressure sensor will not exceed the set threshold, so as to determine that all the drugs in the aerosol product have been ejected.

[0055] The optoelectronic sensor, magnetic switch, and servo motor are all connected to the control system. The pressing drug cylinder 10 is connected to the compressed air source through a pipeline and a solenoid valve group, and the solenoid valve group is connected to the control system. The compressed air source can use an air compressor. The optoelectronic sensor can transmit the collected signal to the control system, and the control system can control the operation of the servo motor and the solenoid valve group.

[0056] The control system is installed inside the housing 4, and a touch screen 11 is also arranged on the surface of the housing. The control system is connected to the touch screen 11. The staff can send instructions to the control system through the touch screen 11, and at the same time, the touch screen 11 can also display the number of times the pressing drug cylinders 10 are pressed down.

[0057] The control system uses a PLC controller. It can be understood that the control system can also use other types of controllers, which can be set by those skilled in the art according to actual needs.

[0058] Furthermore, in order to prevent the drugs ejected from the aerosol product from entering the surrounding environment, causing pollution to the surrounding environment and posing a health threat to the staff, one end of the drug ejection port 5 is connected to one end of a hose, and the other end of the hose is connected to a collection tank.

[0059] The collection tank is connected to a vacuum generator through a vacuum extraction pipe. The vacuum generator can create a vacuum in the collection tank, so that the drugs ejected from the drug ejection port enter the collection tank through the hose.

[0060] The liquid part of the drug is collected in the collection tank.

[0061] The collection tank is also connected to one end of an exhaust pipe, and the other end of the exhaust pipe is connected to a filtering device. The filtering device can use an existing gas filter, and will not be described in detail here.

[0062] To prevent liquid medicine from entering the exhaust pipe and the vacuum extraction pipe, the connection positions of the exhaust pipe and the vacuum extraction pipe with the collection tank are located at the upper positions of the side tank walls.

[0063] Along the gas flow direction, a valve and a fan are sequentially arranged on the exhaust pipe. After the valve is opened, the fan can drive the gas in the collection tank to flow towards the filtering device, and the gas is discharged after being filtered.

[0064] The collection tank includes a tank body, the tank body has an open-top structure, and a tank cover is covered at the open-top of the tank body. A sealing ring is provided between the tank cover and the tank body for sealing.

[0065] After a set amount of liquid medicine is collected in the tank body, the tank cover is opened, and the liquid in the collection tank is poured out to a set position for centralized treatment.

[0066] In this embodiment, through the settings of the collection tank and the filtering device, the liquid part of the medicine is collected in the collection tank, and the gas part is discharged after being filtered by the filtering device, which will not cause pollution to the surrounding environment and will not threaten the physical health of the detection personnel.

[0067] To avoid the influence of the hose on the operation of the photoelectric sensor, the hose is made of a transparent hose, and the transmitting end and the receiving end of the photoelectric sensor are arranged outside the transparent hose. In another embodiment, the transmitting end and the receiving end of the photoelectric sensor are arranged inside the transparent hose, and the transparent hose is detachably connected to the fixture by bolts.

[0068] Furthermore, the bottom of the housing 4 is provided with furniture casters to facilitate the movement of the entire detection device.

[0069] Embodiment 2

[0070] This embodiment provides a working method for a detection device for the number of pressing and spraying times of a pressing and spraying type preparation product described in Embodiment 1. The pressing and spraying type preparation product is an aerosol product, and the method includes the following steps:

[0071] The placement groove of the fixture accommodates the pressing and spraying type preparation product to be detected, and the medicine spraying port of the pressing and spraying type preparation product is aligned with the medicine spraying outlet on the fixture;

[0072] The driving member is rotated to drive the fixture to perform a swinging motion. After reaching the set number of times, the fixture stops swinging, and the pressing and spraying type preparation product corresponds to the downward pressing driving member;

[0073] The pressing drive member works to press the press-to-spray preparation product; the pressing drive member stops working after the set number of pressing times is reached; the rotating drive member drives the clamp to swing again, and the clamp stops swinging after the set number of swinging times is reached, and the press-to-spray preparation product corresponds to the pressing drive member, and the pressing drive member presses again to work; the rotating drive member and the pressing drive member work in a cycle until all the medicines in the press-to-spray preparation product to be tested are ejected, and the number of times the pressing drive member presses the press-to-spray preparation product is recorded.

[0074] The specific steps include:

[0075] Step 1: Place the aerosol product 2 to be tested into the placement slot 3 of the fixture 1 to complete the fixation of the aerosol product 2.

[0076] Step 2: The inspector sends a command to the control system through the touch screen 11. The control system controls the servo motor to work. The servo motor drives the fixture 1 to swing back and forth within the set angle range through the fixed plate 6 to shake the medicine of the aerosol product. After the fixture 1 reaches the set number of swings, the servo motor stops working. At this time, the axis of the placement slot 3 is in a vertical state, and the medicine pressing cylinder 10 is aligned with the aerosol product 2.

[0077] The inspector sends instructions to the control system through the touch screen 11. The control system controls the operation of the medicine pressing cylinder 10 through the electromagnetic valve group. The piston rod of the medicine pressing cylinder 10 extends and presses the aerosol product 2 through the pressing block. At the same time, the touch screen 11 displays the number of times each medicine pressing cylinder 10 is pressed down.

[0078] For each medicine pressing cylinder 10, after each pressing for a set number of times, preferably, the pressing number is set to 3 times, the medicine pressing cylinder 10 stops working, and the servo motor drives the clamp 1 to swing the set number of times within the set angle range again, and shakes the medicine again. After the swing is completed, the aerosol product corresponds to the medicine pressing cylinder 10, and the medicine pressing cylinder 10 works again.

[0079] In this embodiment, the aerosol product is an inhalation aerosol product, and the internal drug liquid is a suspension type. If it is not shaken before use, the sprayed drug liquid will be uneven, and the precipitated and relatively viscous drug may clog the spray hole, resulting in the inability to spray the drug liquid. The aerosol product should be shaken before pressing and after pressing a set number of times to overcome this problem.

[0080] The servo motor and the medicine pressing cylinder work cyclically according to the above process.

[0081] When the medicine pressing cylinder 10 is working, if the photoelectric sensor cannot detect the sprayed medicine, it means that the medicine in the aerosol product is completely sprayed out, and the medicine pressing cylinder 10 stops working. The number of times the medicine pressing cylinder 10 is pressed down is recorded as the total number of times the aerosol product 2 is pressed.

[0082] With the detection device of this embodiment, the entire detection process uses the medicine pressing cylinder 10 to press the aerosol product instead of manual operation, which can ensure the pressing force and stroke, ensure the consistency of the amount of medicine ejected each time, and thus ensure the accuracy of the detection result.

[0083] In this embodiment, the swing angle and swing times of the fixture 1 can be set through the touch screen, and will not be described in detail here.

[0084] It can be understood that the medicine pressing times detection device of this embodiment can also be used to detect the medicine pressing times of nasal sprays, powder aerosols or other topical sprays.

[0085] Embodiment 3

[0086] This embodiment provides a medicine pressing times detection device for pressing and ejecting type preparation products. Compared with Embodiment 1, the fixture is directly fixed on the housing, and no rotation driving member is provided. The medicine pressing cylinder is arranged above the placement groove of the fixture. When using this detection device, it is suitable for the detection of solution-type preparations. When detecting solution-type preparation products, oscillation is not required, so the setting of the rotation driving member is omitted. The rest of the structure of this embodiment is exactly the same as that of Embodiment 1 and will not be repeated here.

[0087] When the medicine pressing times detection device for pressing and ejecting type preparation products of this embodiment works, place the pressing and ejecting type preparation product in the placement groove of the fixture, and then directly use the medicine pressing cylinder to press the pressing and ejecting type preparation product until the pressing and ejecting type preparation product no longer ejects medicine. At this time, record the total pressing times of the medicine pressing cylinder.

[0088] It can be understood that the medicine pressing times detection device of this embodiment can also be used to detect the medicine pressing times of nasal sprays, powder aerosols or other topical sprays.

[0089] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
