Description

Technical Field

[0001] This utility model belongs to the field of sampling device technology, and in particular relates to a liquid sampling device for occupational disease detection. Background Technology

[0002] In occupational disease prevention and diagnosis, liquid sampling and testing is a core component. Occupational diseases are often caused by long-term exposure to harmful factors such as dust, chemical toxins, and radioactive substances. The damage to the human body is often reflected in bodily fluids such as blood, urine, and respiratory secretions. For example, excessive levels of heavy metal ions can be detected in the blood of patients with heavy metal poisoning, characteristic metabolites will appear in the urine of patients with organic solvent poisoning, and abnormal cells or inflammatory factors will be found in the bronchial secretions of patients with respiratory occupational diseases such as pneumoconiosis and occupational asthma. By analyzing these liquid samples, we can accurately determine whether there is occupational injury, as well as the degree of injury and trace the pathogenic factors, providing key evidence for clinical diagnosis and treatment planning. At the same time, taking respiratory occupational disease testing as an example, the degree of lesions in different branches of the bronchi of patients may vary. For example, the composition and concentration of harmful substances in the secretions of the proximal trachea and the terminal bronchi may be different. Therefore, it is often necessary to collect multiple liquid samples of different locations and types during the testing process, and it is necessary to strictly avoid sample confusion in order to comprehensively reflect the patient's physical injury status and ensure the accuracy of the test results.

[0003] For example, Chinese patent CN222584542U discloses a bronchoscopy fluid sampling device, including a central ring frame with several sampling mechanisms slidably mounted on it. Each sampling mechanism includes a long spring with a spring seat fixedly mounted to its outer end. The spring seat is rotatably connected to an aspiration sampling component, which includes a mounting end plate with several aspiration needles mounted on it. During sampling, the aspiration needles are connected to a suction tube on the bronchoscope for sampling. Through the sampling mechanism, the fluid flushed from different tracheal branches is sampled separately during bronchoscopy. This device enables highly efficient and convenient separate sampling of tracheal branches with different lesions within the bronchial tissue during bronchoscopy, significantly reducing the difficulty of sampling and effectively shortening the surgical time.

[0004] The above-mentioned scheme uses a ring-shaped central frame to slide and assemble multiple sampling mechanisms. Each sampling mechanism is connected to the aspiration sampling component by a long spring, which enables separate sampling of different tracheal branches. However, although this scheme solves the problem of sample confusion, the aspiration needle relies on the long spring for suspension and fixation. The elastic restraint of the spring greatly restricts the range of motion of the sampling component. Furthermore, when multiple long springs are used in parallel, the springs are prone to tangling and knotting, which not only affects the smoothness of operation but may also snag the bronchoscope's tubing or other components, increasing the risk of surgical operation. At the same time, the long springs occupy a certain space in the bronchoscope's field of vision, interfering with the doctor's observation of the lesion location.

[0005] To address these issues, we provide a liquid sampling device for occupational disease testing. Utility Model Content

[0006] The purpose of this invention is to provide a liquid sampling device for occupational disease detection. By linking a ring-shaped passage composed of multiple contact plates, U-shaped springs and adsorption blocks with a ring electromagnet, it solves the problems of sample confusion and inflexibility in existing occupational disease detection liquid sampling when multiple pumps are used in parallel and can be removed at the same time.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a liquid sampling device for occupational disease detection, comprising a rotating disk and an annular groove plate. Multiple slots are equidistantly spaced along the circumference of the annular groove plate. Multiple electrical contact pieces, distributed alternately with the slots, are fixedly connected to the outer circumference of the inner wall of the annular groove plate. An annular electromagnet is fixedly connected inside the annular groove plate. A buckle plate is fixedly connected to the top of the annular groove plate. A main control chamber is fixedly connected inside the annular groove plate, and a main controller is installed inside the main control chamber. A cover plate is fixedly connected to the top of the main control chamber. The fixation device includes a laryngeal clamp, the inside of which is fitted with a suction device for aspirating fluid from a patient. An adsorption block that can be attracted by a ring electromagnet is fixedly connected to the outside of the laryngeal clamp, and the adsorption block is snapped into the inside of one of the slots. U-shaped springs are fixedly connected to both sides of the adsorption block, and the U-shaped springs are in contact with adjacent contacting plates.

[0008] The present invention is further configured such that a plurality of the aforementioned contact plates, a plurality of the aforementioned U-shaped spring plates, and a plurality of the aforementioned adsorption blocks form a ring-shaped path connected in parallel with the ring electromagnet.

[0009] The present invention is further configured such that a labeling ring is fixedly connected to the top of the buckle plate, and multiple identification labels corresponding to the buckle are affixed to the outside of the labeling ring.

[0010] The present invention is further provided that a rubber pad is fixedly connected inside the hose clamp.

[0011] The present invention is further configured such that a heat dissipation vent for heat dissipation of the main controller is provided on the top of the cover plate.

[0012] The present invention is further configured such that a rotating shaft is fixedly connected to the top center of the cover plate, and a fixing rod for fixing the entire device is rotatably connected to the outside of the rotating shaft.

[0013] The present invention is further configured such that a pressure plate is movably sleeved on the outside of the fixing rod, a baffle is fixedly connected to the outside of the fixing rod, and a downward pressure spring is movably sleeved on the outside of the fixing rod, with the downward pressure spring located between the baffle and the pressure plate.

[0014] The present invention is further configured such that the cover plate has a plurality of hemispherical grooves equidistantly distributed around the pivot, and the number of hemispherical grooves is the same as the number of bayonet slots, and the bottom of the pressure plate is fixedly connected with a plurality of hemispherical protrusions that are adapted to the hemispherical grooves.

[0015] This utility model has the following beneficial effects: 1. This utility model uses a ring-shaped channel composed of multiple contacting pieces, U-shaped springs and adsorption blocks, and the linkage control between this channel and the ring electromagnet. When all the fixtures are installed in place, the complete ring-shaped channel will de-energize the ring electromagnet, allowing any fixture to be flexibly removed. However, if one fixture is missing, the corresponding channel will be broken, and the ring electromagnet will immediately be energized and firmly hold the remaining fixtures. This allows only one fixture to be removed at a time, avoiding sample confusion. Furthermore, the removable fixtures are freed from constraints, making it more flexible for operators to hold the liquid extractor for sampling. 2. This utility model uses a damping engagement structure of pressure plate, pressure spring, hemispherical protrusion, and groove to prevent the rotating disk from rotating on its own after adjusting the angle of the rotating disk to a position that facilitates sampling, thus ensuring the stability of use.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0018] Please see Figures 1 to 4 This utility model is a liquid sampling device for occupational disease detection, including a rotating disk 100 and an annular groove plate 101. The annular groove plate 101 has multiple slots 101a equidistantly opened on its outer periphery along the circumference. Multiple electrical contact pieces 101b are fixedly connected to the outer periphery of the inner wall of the annular groove plate 101, which are distributed alternately with the slots 101a. An annular electromagnet 102 is fixedly connected inside the annular groove plate 101. A buckle plate 103 is fixedly connected to the top of the annular groove plate 101. A main control chamber 104 is fixedly connected inside the annular groove plate 101. A main controller 105 is installed inside the main control chamber 104. A cover plate 106 is fixedly connected to the top of the main control chamber 104. The fixation device 200 includes a laryngeal clamp 201. The laryngeal clamp 201 houses a suction device 300 for aspirating fluid from a patient. An adsorption block 202, which can be attracted by a ring electromagnet 102, is fixedly connected to the outside of the laryngeal clamp 201. The adsorption block 202 is snapped into the interior of one of the slots 101a. U-shaped spring clips 203 are fixedly connected to both sides of the adsorption block 202, and the U-shaped spring clips 203 are in contact with adjacent contacting plates 101b. The laryngeal clamp 201 can be adjusted according to the fluid aspiration... The outer diameter of the device 300 allows for flexible adjustment of the clamping force, ensuring that the liquid extractor 300 is securely fixed. The adsorption block 202 and the annular electromagnet 102 work together, and the locking and limiting of the bayonet 101a achieves double fixation of the fixture 200 and the rotating disk 100, improving connection stability. The fitting design of the U-shaped spring 203 and the electrical contact piece 101b can provide real-time feedback on the installation status of the fixture 200, facilitating timely adjustments by operators and providing a pathway for subsequent circuit control.

[0019] Specifically, multiple contacting pieces 101b, multiple U-shaped springs 203, and multiple adsorption blocks 202 form a ring-shaped path connected in parallel with the annular electromagnet 102. This parallel ring-shaped path ensures that even if a single contacting piece 101b or U-shaped spring 203 experiences poor contact, other paths can still function normally, improving the reliability of the device's circuitry. The ring-shaped path is compatible with multiple bayonets 101a, supporting the simultaneous installation of multiple fixtures 200 and liquid extractors 300. This enables simultaneous sampling of multiple occupational disease test samples, significantly improving testing efficiency and making it suitable for batch sample testing scenarios. Furthermore, this ring-shaped path forms a linkage control with the annular electromagnet 102. When all fixtures 200 are in place, the U-shaped springs on both sides of each adsorption block 202... The U-shaped springs 203 are all attached to the contact plate 101b, so that the annular electromagnet 102 is short-circuited and not energized. At this time, each fixture 200 is only fixed by the snap-fit ​​101a, and any fixture 200 can be flexibly removed. When one fixture 200 is missing, the U-shaped springs 203 at the corresponding position are disconnected from the contact plate 101b, the integrity of the annular circuit is destroyed, the annular electromagnet 102 is energized and generates magnetic force, firmly attracting the adsorption blocks 202 of the remaining fixtures 200, ensuring that only one fixture 200 can be removed at a time. This effectively avoids the problem of sample misplacement caused by multiple movable fixtures 200 after liquid collection. Moreover, the removable fixtures 200 are freed from restraint, and the operator has greater flexibility when holding the liquid extractor 300 to collect liquid. A labeling ring 112 is fixedly connected to the top of the buckle 103. Multiple identification labels 112a corresponding to the slots 101a are affixed to the outside of the labeling ring 112. Each identification label 112a corresponds to a slot 101a. Each slot 101a corresponds to a fixture 200 and a liquid extractor 300. Operators can quickly distinguish the samples collected by different liquid extractors 300 through the labels, effectively avoiding confusion of occupational disease detection samples and reducing sample management errors. A rotating shaft 107 is fixedly connected to the top center of the cover plate 106. A fixing rod 108 for fixing the entire device is rotatably connected to the outside of the rotating shaft 107. The rotating shaft 107 allows the fixing rod 108 to rotate around the center of the rotating disk 100, which facilitates the adjustment of the fixing angle of the fixing rod 108 according to the sampling environment, improves the installation flexibility of the device, and the fixing rod 108 can firmly fix the entire sampling device on the operating table or bracket.

[0020] Furthermore, a rubber pad 204 is fixedly connected inside the hose clamp 201. The rubber pad 204 is elastic and non-slip. On the one hand, it can buffer the clamping pressure of the hose clamp 201 on the liquid extractor 300, and prevent the liquid extractor 300 from deforming or being damaged due to excessive clamping, thus protecting the sampling tool. On the other hand, it can increase the friction between the hose clamp 201 and the liquid extractor 300, further preventing the liquid extractor 300 from slipping during the sampling process and improving the reliability of the fixation. The top of the cover plate 106 has a heat dissipation vent 106b for heat dissipation of the main controller 105.

[0021] The operation process of this embodiment is as follows: When it is necessary to aspirate the patient's body fluid to be tested, firstly, the adsorption blocks 202 of the fixation device 200, which match the number of slots 101a, are inserted into one slot 101a of the annular groove plate 101, ensuring that the U-shaped spring pieces 203 on both sides of the adsorption block 202 are tightly attached to the adjacent contact pieces 101b. At this time, the annular circuit formed by multiple contact pieces 101b, U-shaped spring pieces 203 and adsorption blocks 202 is complete, the annular electromagnet 102 is short-circuited and not energized, and each fixation device 200 is fixed only by being snapped into place through slots 101a. Then, the suction device 300 to be used is placed into the throat clamp 201 one by one. The clamping force of the throat clamp 201 is adjusted according to the outer diameter of the suction device 300, so that the rubber pad 204 inside the throat clamp 201 is tightly attached to the outer wall of the suction device 300. After that, the identification label 112a on the labeling ring 112 on the top of the buckle plate 103 is observed, and each identification label 112a is recorded and associated with the corresponding... The matching relationship between the bayonet 101a, the fixator 200, and the aspirator 300 avoids subsequent sample confusion. If it is necessary to use the aspirator 300 for sampling, the target fixator 200 is removed. Because the U-shaped spring 203 is disconnected from the contact plate 101b at this position, the integrity of the annular path is destroyed. The annular electromagnet 102 is energized to generate magnetic force, which firmly attracts the adsorption blocks 202 of the other fixators 200, ensuring that only the target fixator 200 is removed. The operator holds the target aspirator 300 to aspirate the patient's body fluid to be tested. After sampling, the aspirator 300 containing the sample is reset along with the fixator 200, so that the adsorption block 202 is re-engaged into the corresponding bayonet 101a, and the U-shaped spring 203 and the contact plate 101b are re-attached, restoring the annular path to its integrity. The annular electromagnet 102 is de-energized. Other fixators 200 can be removed in the same way for subsequent sampling, thereby avoiding sample confusion and increasing the flexibility of sampling. Example 2

[0022] Please see Figure 4 Based on the first specific embodiment, a pressure plate 109 is movably sleeved on the outside of the fixing rod 108, a baffle 110 is fixedly connected to the outside of the fixing rod 108, and a downward pressure spring 111 is movably sleeved on the outside of the fixing rod 108, with the downward pressure spring 111 located between the baffle 110 and the pressure plate 109.

[0023] Specifically, the cover plate 106 has multiple hemispherical grooves 106a equidistantly distributed around the rotating shaft 107, and the number of hemispherical grooves 106a is the same as the number of bayonet slots 101a. The bottom of the pressure plate 109 is fixedly connected to multiple hemispherical protrusions 109a that are adapted to the hemispherical grooves 106a. The matching and engagement of the hemispherical protrusions 109a and the hemispherical grooves 106a can generate a certain damping sensation, preventing the rotating disk 100 from rotating on its own when not in operation, and improving the stability of the device.

[0024] The operation process of this embodiment is as follows: When rotating this device, the operator directly pushes the rotating disk 100. At this time, the rotating disk 100 drives the cover plate 106 to move synchronously. The hemispherical groove 106a on the cover plate 106 and the hemispherical protrusion 109a at the bottom of the pressure plate 109 generate a relative force. The force of the manual push can overcome the damping feeling generated by the two locking together, so that the hemispherical protrusion 109a moves slightly upward under the drive of the pressure plate 109. The downward spring 111 located between the baffle 110 and the pressure plate 109 is then slightly compressed. The hemispherical protrusion 109a temporarily disengages from the hemispherical groove 106a at the current position, and then rotates... The turntable 100 can rotate smoothly around the pivot 107 at the top center of the cover plate 106 until it is adjusted to the required angle. A certain slot 101a and the corresponding retainer 200 and extractor 300 are rotated to a position that is convenient for sampling. When the turntable 100 reaches the target angle, the operator releases the pushing force, and the lower spring 111 resets under the action of elasticity, pushing the pressure plate 109 to move downward, so that the hemispherical protrusion 109a at the bottom of the pressure plate 109 is re-engaged into the hemispherical groove 106a at the corresponding position on the cover plate 106. The damping feeling generated by the matching engagement of the two prevents the turntable 100 from rotating on its own when not in operation.
