Description

Technical Field

[0001] The present application proposes a sampling device for detecting the number of particles inside a purification device, and relates to the technical field of medical environment detection. Background Art

[0002] With the continuous development of the pharmaceutical industry, domestic and international regulations and technical documentation requirements for pharmaceutical production have been continuously improved. Clear regulations have been set for the integrity testing and testing cycles of high-efficiency filters used in pharmaceutical production workshops and equipment such as boiling dryers, spray dryers, coating machines, and tunnel ovens. However, existing sampling system designs, such as photometers, cannot meet these testing requirements.

[0003] Existing testing equipment cannot effectively and accurately reach every required measurement location according to operating instructions. It suffers from blind spots and visual blind spots, resulting in test data that does not represent the true situation. This is because existing sampling devices are not designed to test the specific conditions within the equipment. Existing equipment's sampling tubes are short and have rough interiors, making them unable to bend and position for sampling as required. This makes them unsuitable for sampling in environments where operators cannot access or observe directly.

[0004] Therefore, it is necessary to design a sampling system that can effectively overcome the above difficulties. It can still perform detection operations as normal when personnel cannot enter and directly observe, and can be visible, bendable, and capable of fixed-point positioning collection at any part of the body. It can effectively meet all testing requirements in various clean equipment and special environments. Utility Model Content

[0005] To solve the above technical problems, the present application proposes a sampling device for detecting the number of particles inside a purification device, comprising: a sampling head, a sampling tube, a camera device, a lighting device, an extension tube, a display device, a handle, a detection device, and a display screen;

[0006] The sampling head is rectangular and is used to collect particles in the air inside the purification equipment;

[0007] The top of the sampling tube is a threaded structure for connecting to the threaded port of the sampling head. The sampling tube can be bent at any angle and reach different depths to enable the sampling head to perform directional positioning sampling.

[0008] The top of the extension tube and the handle are both equipped with a circuit interface, an air interface and two stainless steel plug rods; the circuit interface is a circular 7-pin interface for powering the lighting device and the camera device and transmitting data signals; the air interface is a plug-in quick-connect interface to ensure that the sampling airflow can pass through without leakage;

[0009] The bottom of the sampling tube, extension tube and handle are all provided with a circuit connector, a gas circuit connector and two jacks, and the jacks are used to be fixedly connected to the stainless steel rod;

[0010] The sampling tube can be connected to the handle directly or through an extension tube. The handle is connected to the detection equipment through an electric wire harness and a plastic air tube.

[0011] The upper part of the handle is provided with a display device for observing real-time detection values and sampling working images, and the screen of the display device is provided with touch buttons for operation control. The lower part of the handle is the hand-held part of the personnel;

[0012] The detection device is used to detect the number of particles in the air inside the purification device, and the detection results are displayed on the display screen of the detection device and the display device on the handle;

[0013] The lighting device and camera device are arranged on the sampling tube, and can also be oriented and positioned by bending at any angle and at different depths; the lighting device is used to illuminate the internal environment of the purification equipment, and the camera device is used to observe and photograph the internal environment in real time.

[0014] In a preferred embodiment, the sampling tube is a tubular structure with a flat and smooth inner surface, no dead angles, and no electrostatic adsorption.

[0015] In a preferred embodiment, the sampling tube includes: an inner layer, a middle layer and an outer layer; the inner layer is a PP plastic layer with a smooth surface and no static electricity; the middle layer is a fusion layer of metal wire, electric wire and plastic; and the outer layer is a soft plastic layer.

[0016] In a preferred embodiment, the sampling device can save the detection data and collected images, and remotely share them with other devices via wireless signals.

[0017] In a preferred embodiment, the detection device is an aerosol photometer or a laser particle counter.

[0018] Compared with the existing technology, this application has the following beneficial technical effects:

[0019] 1. The sampling tube is bendable and can realize fixed-point positioning collection at any part of the body. The sampling tube in the prior art is a universal joint structure and is relatively short. The shorter sampling tube cannot meet the sampling requirements at any angle and depth, and the connection between the sections is prone to particle retention and adsorption. The inner surface of the sampling tube of the present application is flat and smooth, without dead angles and electrostatic adsorption, and can be bent and hovered at any angle and depth for sampling.

[0020] 2. The sampling devices in the prior art are only suitable for operation when people can enter and have the appropriate body position.

[0021] 3. During the operation of this application, the on-site conditions can be visually detected, the changes in the detection values can be observed at any time, and abnormal data alarms can be issued, effectively meeting all requirements for sampling and testing inside various purification equipment and in special environments.

[0022] 4. Save data to ensure data traceability and integrity. Remote sharing is possible through networking, and screenshots and recordings can be used to save data during the scanning process. When the value does not meet the requirements, a sound prompt will be issued so that the operator can record the data and problem images and review the problem area.

[0023] 5. It must meet the requirements of relevant laws and regulations, meet the relevant content testing requirements of the pharmaceutical industry, be practical and in-demand, have good commercial value, and can be promoted industrially. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The specific implementation methods of the present application are further illustrated below in conjunction with the accompanying drawings, and the technical solutions in the embodiments of the present application are clearly and completely described.

[0032] Figure 1 The schematic diagram of the sampling device is as follows: Figure 1 As shown, the sampling device of the present application includes: a sampling head, a sampling tube, a camera device, a lighting device, an extension tube, a display device, a handle, a detection device and a display screen.

[0033] The sampling head is rectangular and is used to collect the number of particles inside the purification equipment; the sampling tube can pass through completely any angle and reach different depths, so that the connected sampling head can reach any specified position. The top of the sampling tube is a threaded structure and can be connected to the threaded port of the sampling head.

[0034] The sampling tube can be directly connected to the handle or connected through an extension tube as needed.

[0035] The handle is equipped with a display device for viewing real-time test values and sampling working images. The display screen also has touch buttons for simple operation and control. The handle is connected to the test equipment via an electric wire harness and soft plastic air tube.

[0036] The lighting device and camera are mounted on the sampling tube and can be bent at any angle and positioned at different depths. The lighting device is used to illuminate the interior of the purification equipment, while the camera is used to observe and capture real-time images of the interior. When personnel are unable to enter, the lighting and camera devices can illuminate darkness and capture images of the interior of the equipment.

[0037] Preferably, the sampling tube is composed of a composite of plastic and metal wire, is 50-80 cm long, and includes an electric wire and an electric wire connection interface.

[0038] Figure 2 is a schematic diagram of the sampling tube cross section, as shown in Figure 2 As shown, the cross-sectional structure of the sampling tube is divided into three layers. The sampling tube includes: inner layer, middle layer and outer layer;

[0039] The inner layer is a smooth, static-free PP plastic layer, which protects the gas from complete passage without entrapment or adsorption. The middle layer is composed of flexible, shaped metal wire and electrical circuits fused with plastic. It should be noted that the PP plastic layer, metal wire, and soft plastic layers are all purchased conventional materials. The middle layer design enables the sampling tube to bend at any angle and reach different depths to support the sampling head for directional sampling. The outer layer of the sampling tube is a soft plastic layer, which mainly provides safety protection. Figure 2 In the figure, solid circles represent metal wires and hollow circles represent electrical wires.

[0040] Figure 3It is a schematic diagram of the structure of the sampling tube, camera device and lighting device. Figure 3 As shown, the top of the sampling tube is a threaded structure, which is connected to the threaded port of the sampling head; the sampling tube is provided with a lighting device and a camera device, and the connecting rod of the lighting device and the camera device can be bent at any angle and reach different depths for directional positioning like the sampling tube; the bottom of the sampling tube is provided with two connectors for the circuit and the gas path, as shown in FIG. Figure 4 As shown, the sampling tube can be directly connected to the handle, or it can be connected through an extension tube as needed.

[0041] Figure 4 This is the top structure diagram of the extension tube / handle. Figure 4 As shown, the top of the extension tube / handle is provided with two interfaces for circuit and gas circuit and two stainless steel rods for inserting Figure 5 The circuit interface is a circular 7-pin interface (or a TYPE-C interface) for data transmission, used to power the lighting and camera devices and transmit information to the display device. The gas path interface is a plug-in quick-connect interface to ensure that the sample airflow can pass through without leakage.

[0042] Figure 5 This is the bottom structure diagram of the sampling tube / extension tube. Figure 5 As shown, the bottom of the sampling tube / extension tube is provided with two connectors for the circuit and the gas circuit and two jacks. The jacks are used to insert the stainless steel rods to achieve a fixed connection; the circuit connector is a round 7-pin connector for data transmission.

[0043] In a preferred embodiment, the camera device can transmit signals to the display device of the handle through the internal circuit of the sampling tube. The operator can observe while sampling. At the same time, the operator can also connect with the mobile phones of other non-operators through the wireless signals radiated by the camera device, and observe and guide at the same time through the mobile phone screen. All sampling processes can be recorded to ensure the authenticity and completeness of the detection data and the rapid tracing of problems.

[0044] The handle consists of two parts: the upper part houses the display device, and the lower part is the operator's grip. Its shape is ergonomic and easy to hold. A channel for airflow sampling is located inside the handle to ensure that airflow passes through and is transmitted to the detection equipment.

[0045] Figure 6 This is a real picture of the bottom of the handle. Figure 6 As shown, the bottom of the handle is provided with a handle bottom circuit connector and a handle bottom gas circuit connector. The handle bottom circuit connector is a circular 7-pin connector (or a TYPE-C connector) used for power supply and data transmission, and the handle bottom gas circuit connector is a plug-in quick-connect connector.

[0046] The handle is connected to the testing equipment via a wire harness and plastic tubing. Test data is transmitted via the harness to the testing equipment's display and the handle's display. The handle's display allows the operator to observe the testing process and results in real time, with an alarm signaling if data exceeds specified limits.

[0047] The extension tube is designed to be added between the sampling tube and the handle to meet actual length requirements. The inner layer of the extension tube is a rigid stainless steel tube, ensuring it is resistant to bending, smooth, adsorbent, and static-free. The outer layer of the tube is a protective plastic layer with a cable in the middle. Both the top and bottom ends feature circuit and air connections that match the sampling tube and handle, as well as a stainless steel rod for securing the connection. It should be noted that the rigid metal and plastic materials are conventionally purchased.

[0048] When the sampling device of the present application is used for scanning, the sampling head is placed close to the high-efficiency filter. The sampling head first scans the surface of the filter and finally scans the filter frame position for leak detection.

[0049] The sampling device designed in this application can give full play to the capabilities of the detection instrument and overcome existing shortcomings. It can be seen, bent, and can perform fixed-point positioning collection at any part in special environments or when operators cannot enter to detect boiling dryers, coating machines, tunnel ovens and other production equipment, and can effectively preserve the authenticity and integrity of detection data and quickly trace detection problems.

[0050] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
