Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical testing equipment technology, and in particular to a pharmaceutical strong light stability test chamber. Background Technology

[0002] In the research, development, production, and storage of pharmaceuticals, drug stability is one of the important indicators for evaluating drug quality. Strong light exposure is a significant factor affecting drug stability; many drugs are prone to degradation and deterioration under strong light conditions, thus impacting their efficacy and safety. Therefore, it is necessary to conduct strong light stability tests on drugs to determine their stability under strong light conditions, providing a scientific basis for drug packaging, storage, and transportation.

[0003] Existing pharmaceutical light stability test chambers suffer from uneven light coverage, with some areas experiencing insufficient or excessive light intensity, leading to inaccurate test data; low temperature control precision, failing to maintain the required temperature environment for testing, thus affecting the reliability of test results; poor airflow circulation within the chamber, resulting in uneven temperature distribution; poor sealing performance, making it prone to heat or light leakage; and a lack of convenient observation structures, hindering real-time monitoring of the pharmaceutical status. Utility Model Content

[0004] The purpose of this invention is to solve the problems of uneven illumination and low temperature control accuracy in existing devices, and to propose a pharmaceutical strong light stability test chamber.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pharmaceutical strong light stability test chamber, comprising a test chamber, a strong light component, and a temperature component. The strong light component is fixedly connected to the inner top wall of the test chamber, and the temperature component is fixedly connected to the inner side wall of the test chamber. The strong light component includes an LED light panel fixedly connected to the inner top wall and inner side wall of the test chamber, and reflectors on the inner top wall and inner side wall of the test chamber. The temperature component includes a heating tube fixedly connected to the inner wall of the test chamber, a heating wire fixedly connected to the inner wall of the heating tube, and a semiconductor cooling chip fixedly connected to the inner wall of the test chamber. A sealed door is rotatably connected to the front of the test chamber, and a light and temperature control panel is fixedly connected to the top of the front of the sealed door.

[0006] Furthermore, the inner wall of the test chamber is fixedly connected to a placement slot plate, and a temperature sensor is fixedly connected to the top of each of the two placement slot plates.

[0007] Furthermore, a medicine plate is fixedly connected to the inner bottom wall of the test chamber, and a sponge pad is fixedly connected to the inner bottom wall of the two placement slots and the top of the medicine plate.

[0008] Furthermore, an observation window is provided on the surface of the sealed chamber door, and two mounting grooves are provided on the inner top wall of the test chamber.

[0009] Furthermore, circulating fans are fixedly connected to the inner walls of the two mounting slots, and the heating tubes and semiconductor cooling chips are installed in a staggered and cross manner.

[0010] Furthermore, the heating element is made of stainless steel, and the test chamber is made of thermal insulation material.

[0011] Furthermore, an air cushion sealing strip is fixedly connected to the surface of the sealed chamber door, and a suction cup is fixedly connected to the bottom of the test chamber.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up a high-intensity light component and a temperature component, the LED light panels of the high-intensity light component are respectively installed on the top wall and inner side wall of the test chamber, and together with the reflector to reflect light, it achieves all-round light coverage inside the chamber, avoids uneven local lighting, ensures that all parts of the medicine receive consistent light, and improves the accuracy of test data. The heating tube of the temperature component heats up through an electric heating wire and cools down with a semiconductor cooling chip. Together with the photometric and temperature control panel, the temperature inside the chamber is precisely regulated to meet the temperature requirements of different medicine tests, solving the problem of low temperature control accuracy in existing devices. The placement tray and medicine tray provide multi-layer medicine placement space, and the sponge pad prevents medicine from touching the surface of the medicine. Even if the test chamber is damaged by a collision, the temperature sensor monitors the internal temperature in real time and sends feedback to the control panel to ensure temperature stability. The circulating fan accelerates airflow within the chamber, resulting in a more uniform temperature distribution. The staggered installation of heating elements and semiconductor cooling chips further enhances temperature control efficiency. The stainless steel heating elements are corrosion-resistant, and the test chamber made of insulation material reduces heat loss. The air-cushioned sealing strip on the sealed door enhances the airtightness and prevents heat and light leakage. The observation window allows for real-time monitoring of the drug's condition, and the suction cups enhance the stability of the test chamber. Overall, the reliability, convenience, and safety of the test are improved, meeting the requirements for testing the stability of drugs under strong light. Attached Figure Description

[0021] Please see Figure 1-5 This utility model provides a technical solution: a pharmaceutical strong light stability test chamber, including a test chamber 1, a strong light component 2 and a temperature component 3. The strong light component 2 is fixedly connected to the inner top wall of the test chamber 1, and the temperature component 3 is fixedly connected to the inner side wall of the test chamber 1.

[0022] The following section will explain the specific settings and functions of its high-intensity light component 2 and temperature component 3.

[0023] In this embodiment: the high-intensity light component 2 includes an LED light panel 21 fixedly connected to the top wall and inner side wall of the test chamber 1, a reflector 22 on the top wall and inner side wall of the test chamber 1, the temperature component 3 includes a heating tube 31 fixedly connected to the inner wall of the test chamber 1, an electric heating wire 32 fixedly connected to the inner wall of the heating tube 31, a semiconductor cooling chip 33 fixedly connected to the inner wall of the test chamber 1, a sealed chamber door 34 rotatably connected to the front of the test chamber 1, and a light and temperature control panel 35 fixedly connected to the top of the front of the sealed chamber door 34.

[0024] The effects achieved by the above components are as follows: by setting up LED light panel 21 to provide strong light irradiation from the top and inner side walls of the test chamber 1, and cooperating with reflector 22 to reflect the light, the light coverage inside the chamber is achieved in all directions without dead angles, ensuring that all parts of the medicine are evenly illuminated; the heating wire 32 in the heating tube 31 is energized to generate heat, providing the heating power for the chamber, and the semiconductor cooling chip 33 achieves cooling, and the two work together to meet the temperature regulation requirements of the test; the photometric and temperature control panel 35 can precisely control the light intensity of LED light panel 21 and the working status of heating tube 31 and semiconductor cooling chip 33. After the sealed chamber door 34 is closed, a sealed test space is formed to prevent light and heat leakage and ensure the stability of the test environment.

[0025] Please see Figure 4 Specifically, the inner wall of the test chamber 1 is fixedly connected with a placement slot plate 4, and the top of the two placement slot plates 4 are fixedly connected with temperature sensors 5.

[0026] The effects achieved by the above components are as follows: by setting up the placement tray 4 to provide multiple drug placement positions, multiple drug tests can be carried out at the same time, improving test efficiency; the temperature sensor 5 monitors the temperature near the placement tray 4 in real time and feeds the temperature data back to the photometric temperature control panel 35 to ensure that the temperature in different areas of the chamber is maintained within the required range for the test, and to avoid temperature deviation from affecting the test results.

[0027] Please see Figure 4 Specifically, a medicine plate 6 is fixedly connected to the inner bottom wall of the test chamber 1, and a sponge pad 7 is fixedly connected to the inner bottom wall of the two placement slots 4 and the top of the medicine plate 6.

[0028] The effects achieved by the above components are as follows: by setting up the medicine plate 6, the medicine placement space is further expanded to accommodate medicine containers of different sizes; the sponge pad 7 buffers the contact and collision between the medicine and the placement slot plate 4 and the medicine plate 6, avoiding damage to the medicine containers, and at the same time reducing the positional displacement of the medicine during the test, ensuring stable test conditions.

[0029] Please see Figure 1-5 Specifically, the surface of the sealed door 34 is provided with an observation window 8, and the inner top wall of the test chamber 1 is provided with two mounting grooves 9.

[0030] The effects achieved by the above components are as follows: by setting the observation window 8, the status changes of the medicines inside the chamber can be viewed in real time without opening the sealed chamber door 34, avoiding fluctuations in the test environment caused by opening the door; the mounting slot 9 provides a fixed space for the subsequent installation of airflow circulation-related components, ensuring that the components are installed stably and do not affect the layout of the test space inside the chamber.

[0031] Please see Figure 4-5 Specifically, the inner walls of the two mounting slots 9 are fixedly connected with circulating fans 10, and heating tubes 31 and semiconductor cooling chips 33 are installed in a staggered and cross manner.

[0032] The effects achieved by the above components are as follows: by setting up the circulating fan 10 to accelerate the air flow inside the chamber, the heat generated by the heating tube 31 and the cold energy generated by the semiconductor cooling chip 33 are quickly diffused to various areas inside the chamber, avoiding uneven local temperature; the heating tube 31 and the semiconductor cooling chip 33 are installed in a staggered manner, which further expands the temperature control coverage, improves the temperature regulation efficiency, and ensures that the temperature inside the chamber quickly reaches and is stably maintained at the value required for the test.

[0033] Please see Figure 3 Specifically, the heating tube 31 is made of stainless steel, and the test chamber 1 is made of insulation material.

[0034] The effects achieved by the above components are as follows: by setting the heating tube 31 made of stainless steel, it has good corrosion resistance and high temperature resistance, which extends the service life of the heating tube 31 and avoids damage caused by high temperature or environmental factors; the test chamber 1 made of heat insulation material can effectively reduce the exchange of heat between the chamber and the outside, reduce the energy consumption of temperature regulation, and at the same time maintain the stability of the temperature inside the chamber, reducing the impact of temperature fluctuations on the test.

[0035] Please see Figure 2-3 Specifically, an air cushion sealing strip 11 is fixedly connected to the surface of the sealed chamber door 34, and a suction cup 12 is fixedly connected to the bottom of the test chamber 1.

[0036] The effects achieved by the above components are as follows: by setting the air cushion sealing strip 11, the gap between the door and the box body is filled when the sealed box door 34 is closed, which enhances the sealing performance of the test box 1, prevents light leakage inside the box from affecting the test accuracy, and reduces heat loss to maintain temperature stability; the suction cup 12 enhances the adsorption force between the test box 1 and the placement table, avoids the test box 1 from shifting due to accidental collision during the test, and ensures the safe and stable conduct of the test.

[0037] Working principle: By setting up a high-intensity light component 2 and a temperature component 3, the LED light panel 21 of the high-intensity light component 2 is installed on the top wall and inner side wall of the test chamber 1 respectively. With the help of the reflector 22 to reflect light, it can achieve all-round light coverage inside the chamber, avoid uneven local lighting, ensure that all parts of the medicine are illuminated, and improve the accuracy of test data. The heating tube 31 of the temperature component 3 heats up through the heating wire 32 and cools down through the semiconductor cooling chip 33. With the help of the photometric and temperature control panel 35, the temperature inside the chamber is precisely controlled to meet the temperature requirements of different medicine tests and solve the problem of low temperature control accuracy in existing devices. The placement tray 4 and the medicine plate 6 provide multi-layer medicine placement space, and the sponge pad 7 prevents the medicine from touching the surface of the medicine. In the event of a collision damage to the test chamber, temperature sensor 5 monitors the internal temperature in real time and sends feedback to the control panel to ensure temperature stability. Circulating fan 10 accelerates airflow within the chamber, resulting in a more uniform temperature distribution. The staggered installation of heating tube 31 and semiconductor cooling chip 33 further enhances temperature control efficiency. The stainless steel heating tube 31 is corrosion-resistant, and the test chamber 1, made of insulation material, reduces heat loss. The air-cushion sealing strip 11 on the sealed door 34 enhances the airtightness and prevents heat and light leakage. The observation window 8 allows for real-time monitoring of the drug's condition, and the suction cup 12 enhances the stability of the test chamber 1. Overall, this improves the reliability, convenience, and safety of the test, meeting the requirements for strong light stability testing of drugs.
