Technical Field

[0001] The utility model belongs to the technical field of biological cabinets, and in particular relates to a biological safety cabinet which is convenient to operate. Background Art

[0002] As an indispensable equipment for scientific research and production departments such as medical, pharmaceutical, food, bioengineering and scientific experiments, the core function of biological safety cabinets is to create a local sterile and dust-free environment to ensure the safety and purity of the experimental process. However, with the rapid development of the fields of medicine, health and biological sciences, the currently widely used biological safety cabinets have made significant progress in power equipment and integrated operation, but they are still insufficient in meeting the actual needs of experimental operators.

[0003] It is particularly noteworthy that during experimental operations, the user's arms often need to be bent for a long time, and the elbows are often placed on the operating table. However, the operating table of traditional biosafety cabinets is often designed to be flat. This design makes the experimenter feel obvious discomfort in the elbows during long-term operation, greatly affecting the convenience and durability of the operation.

[0004] Therefore, it is very necessary to invent a biosafety cabinet that is easy to operate. Summary of the invention

[0005] In order to solve the above technical problems, the utility model provides a conveniently operated biosafety cabinet, comprising an operating table, a hand-held table, an integrated current collecting cabinet, a glass front window and a bracket, wherein the operating table and the hand-held table are fixed to each other; the operating table is fixedly mounted on the integrated current collecting cabinet, the glass front window is mounted on the integrated current collecting cabinet, and the bracket is fixedly mounted below the glass front window;

[0006] The hand rest platform includes a water-proof platform, a movable installation groove, a sliding ball, an elbow pad and a limiting ring. The water-proof platform is fixed to the operating table. Two mirror-symmetrical movable installation grooves are provided on the water-proof platform. A plurality of sliding balls are movably installed in the movable installation grooves. The sliding ball is in contact with the elbow pad, and the elbow pad is slidably restricted in the movable installation groove by the limiting ring.

[0007] Preferably, two waste liquid collecting tanks are provided on the operating table, one of which is located on one side of the hand-held table, and the waste liquid collecting tank is located below the glass front window; the inner surface of the water barrier is provided with a sealing strip in contact with the glass front window.

[0008] Preferably, the water barrier is a rectangular structure with rounded corners, the outer surface of the water barrier is smooth, the upper surface of the water barrier and the upper surface of the operating table have a height difference, and the upper surfaces of the two are not aligned.

[0009] Preferably, the movable mounting groove is composed of a receiving groove, an auxiliary groove and a ball cavity. The receiving groove is an arc-shaped groove, the auxiliary groove is located above the receiving groove, and the ball cavity is located below the receiving groove. Several sliding balls are installed in the ball cavity, and the limit ring is installed in the auxiliary groove.

[0010] Preferably, the elbow pad is formed by cutting off a quarter of a complete sphere, and has a concave curved surface. An air cushion is provided on the inner surface of the elbow pad.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model specially introduces a hand rest table with unique functions. It is equipped with two carefully designed concave areas, which are specially designed to provide comfortable support for the user's arm elbows. Compared with the traditional flat placement design, this concave structure is more ergonomic and provides more comfortable and stable support for the experimenter's elbows. What's more clever is that the elbow pad on the hand rest table can rotate flexibly. When the experimenter needs to move or turn his arm, the elbow pad can rotate with the movement of the elbow, effectively avoiding the wear and friction of the elbow skin caused by long-term fixed position, greatly improving the user's operating experience. In addition to the above-mentioned comfort and ergonomic design, the hand rest table also has a water-proof effect. During scientific research or experiments, the accidental overflow of waste liquid may have adverse effects on equipment and working environment. The hand rest table design of the utility model can, to a certain extent, prevent waste liquid from overflowing to external areas when it is not handled in time, ensuring the safety and cleanliness of the experimental environment.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a conveniently operated biosafety cabinet, comprising an operating table 1, a hand-held table 2, an integrated current collecting cabinet 3, a glass front window 4 and a bracket 5, wherein the operating table 1 and the hand-held table 2 are fixed to each other; the operating table 1 is fixedly mounted on the integrated current collecting cabinet 3, the glass front window 4 is mounted on the integrated current collecting cabinet 3, and the bracket 5 is fixedly mounted below the glass front window 4. The hand-held table 2 can prevent waste liquid from overflowing to the external area when it is not processed in time to a certain extent, thereby ensuring the safety and cleanliness of the experimental environment.

[0022] The hand platform 2 includes a water-proof platform 21, a movable installation groove 22, a sliding ball 23, an elbow pad 24 and a limiting ring 25. The water-proof platform 21 is fixed to the operating table 1. Two mirror-symmetrical movable installation grooves 22 are provided on the water-proof platform 21. A plurality of sliding balls 23 are movably installed in the movable installation grooves 22. The sliding balls 23 are in contact with the elbow pad 24, and the elbow pad 24 is slidably restricted in the movable installation groove 22 by the limiting ring 25. The hand platform 2 can be flexibly rotated. When the experimenter needs to move or rotate his arm, the elbow pad can rotate with the movement of the elbow, which effectively avoids the wear and friction of the elbow skin caused by being fixed in position for a long time, and greatly improves the user's operating experience. Example

[0023] Specifically, two waste liquid collection tanks are provided on the operating table 1, one of which is located on one side of the hand-held platform 2, adjacent to and below the glass front window 4. It is not only convenient for the rapid collection of waste liquid during the experiment, but also can effectively prevent the waste liquid from accidentally overflowing and contaminating other areas of the hand-held platform or the operating table; the inner surface of the water-proof platform 21 is provided with a sealing strip in contact with the glass front window 4, ensuring a seamless connection between the water-proof platform 2 and the glass front window 4, effectively preventing waste liquid or water from seeping through the gap, and further ensuring the dryness and cleanliness of the experimental environment. The introduction of the sealing strip not only improves the water-proof performance of the water-proof platform, but also enhances the overall sealing and safety of the operating table.

[0024] Specifically, the water barrier 21 is a rectangular structure with rounded corners, which increases the safety of use and reduces accidental scratches that may be caused by sharp edges. The outer surface of the water barrier 21 is polished, which is not only easy to clean, but also effectively prevents waste liquid from remaining on its surface, further ensuring the cleanliness of the experimental environment. There is a significant height difference between the upper surface of the water barrier 21 and the upper surface of the operating table 1, and the upper surfaces of the two are not aligned. This design enables the water barrier 21 to form an independent area to prevent retained waste liquid from overflowing.

[0025] Specifically, the movable installation groove 22 is composed of a storage groove, an auxiliary groove and a ball cavity. The storage groove is an arc-shaped groove. The auxiliary groove is located above the storage groove, and the ball cavity is located below the storage groove. Several sliding balls 23 are installed in the ball cavity, and the limiting ring 25 is installed in the auxiliary groove. The ball 23 can provide a smooth sliding effect when the experimenter moves the arm, reduce the friction between the arm and the installation groove, and further increase the comfort of use. The design of the ball cavity also takes into account the replacement and maintenance of the ball 23, which is convenient for the experimenter to perform maintenance and repair during use. In addition, a limiting ring 25 is also installed in the auxiliary groove. The main function of the limiting ring 25 is to limit the movement range of the sliding ball 23 and the elbow pad 24, prevent the ball 23 from sliding out of the ball cavity when not needed, thereby ensuring the stability and safety of the installation groove. The design of the limiting ring fully considers the diameter of the ball 23 and the size of the ball cavity, ensuring that the ball can slide smoothly when needed without excessive movement.

[0026] Specifically, the elbow pad 24 is formed by cutting off a quarter of a complete sphere, which can provide excellent support and comfort for the user's elbow. The shape of the elbow pad 24 presents a concave curved surface, which perfectly fits the natural shape of the human elbow. When the user places the elbow on the elbow pad 24, the curved surface can completely wrap the elbow, providing all-round support for the elbow, and effectively reducing the discomfort caused by long-term operation. In addition, in order to further improve the user's comfort, an air cushion is specially provided on the inner surface of the elbow pad 24. The air cushion is made of soft and elastic material, which can further buffer the contact pressure between the elbow and the elbow pad, and reduce friction and wear. At the same time, the air cushion also has a certain air permeability, which can keep the elbow skin dry and comfortable, and prevent moisture and discomfort caused by long-term contact. Example

[0027] Negative pressure protection and air circulation: The negative pressure system inside the integrated collector cabinet 3 maintains a negative pressure environment to ensure that the outside air does not enter the cabinet directly without being filtered. At the same time, the internal airflow circulates through the high-efficiency filtration system to ensure the clean air in the operating area.

[0028] Waste liquid collection and isolation: A waste liquid collection tank is provided on the operating table 1 to collect waste liquid generated during the experiment. The design of the water isolation table 2 forms an independent waste liquid isolation area, which effectively prevents waste liquid from overflowing and contaminating the operating table and experimental environment.

[0029] Flexible rotation of the hand platform: The hand platform 1 realizes the function of flexible rotation through the design of the movable mounting groove 22 and the sliding ball 23. When the experimenter needs to move or rotate the arm, the elbow pad 24 can rotate with the movement of the elbow, which greatly improves the flexibility and comfort of the operation.

[0030] Sealing and protection: The sealing strip design between the inner side of the water isolation platform 2 and the glass front window 4 effectively prevents waste liquid or water from seeping through the gap, ensuring the dryness and cleanliness of the experimental environment. At the same time, it also enhances the overall sealing and safety of the operating table.

[0031] Workflow

[0032] Preparation: Before starting the experiment, make sure the biosafety cabinet is in normal working condition. Check whether the waste liquid collection tank and water isolation table 2 are clean, and prepare the necessary experimental items.

[0033] Experimental operation: The experimenter performs the experimental operation on the operating table and pours the waste liquid into the waste liquid collection tank in time. During the experiment, the elbow of the arm can be placed on the elbow rest 24, and the sliding ball 23 and the limit ring 25 can realize the flexible rotation of the hand rest.

[0034] Waste liquid treatment: After the experiment, clean the waste liquid collection tank and water isolation table 2 to ensure that there is no waste liquid residue. Dispose of the waste liquid according to regulations and clean the operating table 1 and hand-held table 2.

[0035] Equipment maintenance: Regularly maintain and service the biosafety cabinet, including replacing filters, checking seals, etc., to ensure the normal operation of the equipment and the safety of the experimental environment.

[0036] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
