After a period of use, the surface of the operation platform and the bottom of the operation table are easy to hide dirt, which leads to the difficulty of cleaning the whole operation platform, and the subsequent use causes a high risk of cross contamination. UTILITARY MODEL CONTENT

[0003] The utility model embodiment provides a mobile operation platform, aims at solving the problem that the surface of the existing operation platform and the bottom of the operation table are easy to hide dirt.

[0004] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of:

[0005] Provide a mobile operation platform, comprising:

[0006] Operation table, with a plurality of upper and lower through holes;

[0007] A plurality of supporting legs are arranged below the operation table respectively;

[0008] A plurality of universal wheels are arranged at the lower ends of the supporting legs respectively;

[0009] Drainage tray, arranged directly below the operation table and detachably connected with the operation table, the drainage tray can receive the liquid discharged from the through hole, the drainage tray is formed with an exhaust passage and a liquid discharge passage, and the height of the exhaust passage is higher than that of the liquid discharge passage.

[0010] In a possible implementation manner, the side wall plate of the drainage tray is arranged spaced apart from the lower surface of the operation table to form an exhaust gap, and the exhaust gap is the exhaust passage.

[0011] In some embodiments, a liquid discharge port is formed in the bottom wall plate of the drainage tray, and the liquid discharge port forms the liquid discharge passage.

[0012] In a possible implementation manner, a control valve is arranged at the liquid discharge port.

[0013] In a possible implementation manner, the mobile operation platform further comprises a supporting frame arranged below the operation table and connected with the supporting legs respectively to limit the displacement of the supporting legs in the direction perpendicular to the up-down direction.

[0014] In a possible implementation, the operation table is a rectangular member, four legs are arranged at four corners of the operation table respectively; the support frame comprises a support vertical rod and two support horizontal rods, the two support horizontal rods are arranged at two short sides of the operation table respectively and support two legs on the corresponding side respectively; the support vertical rod is parallel to the long side of the operation table, and two ends of the support vertical rod are connected to the two support horizontal rods respectively.

[0015] In a possible implementation, the operation table comprises a frame and a table body, the table body is connected to the inner side of the frame, and the leg is connected to the lower part of the frame, and the through hole is arranged on the table body.

[0016] In some embodiments, the table surface of the table body is not higher than the upper end surface of the frame.

[0017] In some embodiments, the mobile operation platform further comprises a handle, and the handle is detachably connected to the frame.

[0018] In a possible implementation, the universal wheel is provided with a brake device.

[0019] Compared with the prior art, the scheme shown in the embodiments of the application has the following beneficial effects:

[0020] 1. The existing cell preparation, virus preparation, virus liquid preparation, vaccine semi-finished product preparation, culture solution preparation and other operation processes need to be carried out in a certain protective atmosphere environment, and the gas is often ventilated from the top to the bottom of the operation platform. Since the existing operation platform is not provided with a through hole, the gas contacts the surface of the operation platform and then escapes from the side, and flows away from the side of the operation platform. In this process, if the gas flow rate is too large, it is easy to cause turbulence above the operation table, blow away the sample, and even cause cross contamination. If the gas flow rate is too small, it cannot play an effective protection role, so it is difficult to control the gas flow rate. By arranging the through hole penetrating from top to bottom, the protective gas is introduced into the top of the operation table to carry out sterile operation, and the gas above the operation table can be discharged downward through the through hole to prevent turbulence from occurring above the operation table, affecting the work, and even causing mutual contamination between samples. At the same time, the exhaust passage can timely exhaust the gas flowing to the lower part of the operation table to avoid the problem that the excessive gas pressure in the lower part of the operation table affects the stability of the whole operation table. Therefore, the arrangement of the through hole effectively avoids the generation of turbulence above the operation table, and the flow rate control difficulty of the protective gas release is relatively low.

[0021] 2、If liquid substance is used in the operation process, the liquid substance spilled on the operation table can be discharged into the drainage tray through the through hole in time, avoiding the problem of cross contamination caused by the accumulation of liquid on the table top of the operation table. At the same time, the liquid flowing into the drainage tray can be discharged in time through the drainage channel, so that the liquid is collected in the designated waste liquid storage container, avoiding the problem of overflow of the liquid from the exhaust channel or the upward reflux of the liquid from the through hole, which affects the reliability of the operation table. Based on this, the table top of the operation table will not accumulate liquid, which can avoid the problem of cross contamination caused by liquid during operation, and can also avoid the problem of difficulty in cleaning the corners of the table top due to the accumulation of liquid and the delay in cleaning, thereby reducing the difficulty in cleaning the table top. In addition, since the drainage tray can be detached from the bottom of the operation table, the drainage tray can be thoroughly cleaned to avoid the problem of pollution caused by incomplete cleaning during the next use.

[0022] 3、Since the bottom of the supporting leg under the operation table is provided with a universal wheel, the operation table can be easily moved to a new position when needed. In this way, after the operation is completed, the operation table can be pushed away, and the ground in this area can be more thoroughly cleaned. At the same time, the universal wheel can also be more thoroughly cleaned, avoiding the problem that the accumulated substances between the supporting leg and the ground are difficult to clean thoroughly due to the immobility of the operation platform, which easily causes pollution to the operating room environment during the next use.

[0023] In general, the mobile operation platform of the present application effectively avoids the cross contamination risk caused by ventilation, effectively avoids the cross contamination risk caused by the accumulation of liquid on the table top of the operation table, effectively avoids the difficulty in subsequent cleaning caused by the accumulation of liquid on the table top of the operation table, and also avoids the risk that the area where the supporting leg contacts the ground is difficult to clean due to the immobility of the operation platform. It can be seen that the mobile operation platform of the present application has lower cleaning difficulty and is less likely to cause cross contamination, and has better use reliability.

[0035] In the claims, the specification, and the above drawings of the utility model, unless there is an explicit definition, if the term "fixedly connected" or "fixedly connected" is used, it should be understood broadly, that is, any connection mode without displacement relationship and relative rotation relationship between the two, that is, it includes non-detachable fixed connection, detachable fixed connection, integration and fixed connection through other devices or elements.

[0036] In the claims, the specification, and the above drawings of the utility model, if the terms "including", "having" and their variants are used, it is intended to mean "including but not limited to".

[0037] Please see Figures 1 to 3 , now the mobile operation platform provided by the utility model will be described. The mobile operation platform comprises an operation table 1, a supporting leg 2, a universal wheel 3 and a drainage tray 4; the operation table 1 has a plurality of through holes 5 penetrating up and down; the supporting leg 2 is provided with a plurality of supporting legs 2, and the plurality of supporting legs 2 are arranged below the operation table 1 respectively; the universal wheel 3 is provided with a plurality of universal wheels 3, and the plurality of universal wheels 3 are arranged at the lower ends of the corresponding supporting legs 2 respectively; the drainage tray 4 is arranged directly below the operation table 1 and is detachably connected with the operation table 1, the drainage tray 4 can receive the liquid discharged from the through holes 5, the drainage tray 4 is formed with an exhaust passage and a liquid discharge passage, the height of the exhaust passage is higher than that of the liquid discharge passage, so that the liquid is prevented from overflowing from the exhaust passage.

[0038] Compared with the prior art, the mobile operation platform provided in the embodiment has the following beneficial effects:

[0039] 1. The existing cell preparation, virus preparation, virus liquid preparation, vaccine semi-finished product preparation, culture solution preparation and other operation processes need to be carried out in a certain protective atmosphere environment, and the air is often ventilated from top to bottom of the operation platform. Since the existing operation platform is not provided with through holes 5, the gas contacts the surface of the operation platform and then escapes from the side, and flows away from the side of the operation platform. In this process, if the gas flow rate is too large, turbulence may be generated above the operation table 1, the samples may be blown away, and even cross contamination may be caused. If the gas flow rate is too small, the protective effect cannot be achieved. Therefore, it is difficult to control the gas flow rate. By arranging the through holes 5 penetrating up and down, the protective gas is introduced into the upper part of the operation table 1 to facilitate sterile operation. The gas above the operation table 1 can be discharged downward through the through holes 5, so that turbulence is prevented from being generated above the operation table 1, the work is not affected, and even the problem of mutual contamination between samples is avoided. At the same time, the exhaust passage can timely exhaust the gas flowing to the lower part of the operation table 1, so that the problem of excessive air pressure in the lower part of the operation table 1 affecting the stability of the whole operation table 1 is avoided. Therefore, the arrangement of the through holes 5 effectively avoids the generation of turbulence above the operation table 1, and the flow rate control difficulty of the protective gas release is relatively low.

[0040] 2、If liquid substances are used in the operation process, the liquid substances spilled on the operation table 1 can be discharged into the drainage tray 4 through the through hole 5 in time, avoiding the problem of cross contamination caused by the accumulation of liquid on the surface of the operation table 1. At the same time, the liquid flowing into the drainage tray 4 can be discharged in time through the liquid discharge channel, so that the liquid is collected in the designated waste liquid storage container, avoiding the problem that the liquid accumulates too much in the drainage tray 4 and overflows from the exhaust channel, or flows back upward from the through hole 5, affecting the reliability of the operation table 1. Based on this, there is no liquid accumulation on the surface of the operation table 1, which can avoid the problem of cross contamination caused by liquid contamination during operation, and can also avoid the problem of difficulty in cleaning due to liquid accumulation and untimely cleaning, which reduces the difficulty of cleaning the surface of the operation table 1. In addition, since the drainage tray 4 can be detached from the bottom of the operation table 1, the drainage tray 4 can be thoroughly cleaned, avoiding the problem of contamination due to incomplete cleaning the next time it is used.

[0041] 3、Since the bottom of the supporting leg 2 below the operation table 1 is provided with the universal wheel 3, the operation table 1 can be easily moved to a new position when needed. In this way, after the operation is completed, the operation table 1 is pushed away, and the ground in this area can be more thoroughly cleaned. At the same time, the universal wheel 3 can also be more thoroughly cleaned, avoiding the problem that the operation platform cannot be moved, causing the accumulated substances between the supporting leg 2 and the ground to be difficult to clean thoroughly, which easily causes pollution to the operating room environment the next time it is used.

[0042] Overall, the mobile operation platform of the present embodiment effectively avoids the cross contamination risk brought by ventilation, effectively avoids the risk of cross contamination caused by liquid accumulation on the surface of the operation table 1, effectively avoids the risk of subsequent cleaning difficulty caused by liquid accumulation on the surface of the operation table 1, and also avoids the risk that the area where the supporting leg 2 contacts the ground is difficult to clean because the operation platform is not movable. It can be seen that the mobile operation platform of the present embodiment has lower cleaning difficulty and is not easy to cause cross contamination, and has better use reliability.

[0043] In some embodiments, referring to Figure 3 , the side wall plate 410 of the drainage tray 4 is spaced apart from the lower surface of the operation table 1 to form an exhaust gap 6, which is an exhaust channel. In the present embodiment, the upper and lower widths of the exhaust gap 6 are 10mm~20mm, which can meet the exhaust demand while avoiding liquid from easily splashing out of the exhaust gap 6. The present embodiment realizes the exhaust function through the exhaust gap 6, without the need to additionally open a channel on the drainage tray 4, and the structure of the drainage tray 4 is simpler. Furthermore, after the gas flows downward into the drainage tray 4, it is decelerated and diverted by colliding with the bottom wall plate 420 of the drainage tray 4, which can better realize lateral escape through the exhaust gap 6.

[0044] Optionally, the exhaust gap 6 is continuously distributed along the circumference of the drainage tray 4, or the exhaust gap 6 is arranged corresponding to one side or both sides of the drainage tray 4, which can meet the exhaust requirement and is not limited herein.

[0045] On the basis of the exhaust gap 6, in order to realize the liquid drainage function, in some embodiments, referring to Figure 3 In order to facilitate liquid drainage, a liquid drainage port 7 is arranged on the bottom wall plate 420 of the drainage tray 4, and the liquid drainage port 7 forms a liquid drainage channel. The liquid drainage port 7 is connected with a waste liquid storage container through a pipeline, so as to realize directional collection of the waste liquid.

[0046] On the basis of the above embodiments, a control valve is arranged at the liquid drainage port 7 to control whether the liquid flows. Optionally, the control valve is a mechanical one-way valve. When the liquid in the drainage tray 4 accumulates to a certain degree, the weight of the liquid downwardly presses the valve core of the mechanical one-way valve, the valve core moves to make the control valve conductive, and at the same time, the elastic element in the control valve is elastically deformed; after a certain amount of liquid is discharged, the gravity of the liquid is not enough to overcome the elastic force of the elastic element, the elastic element releases the elastic energy to drive the valve core to reset, and the control valve is closed. By adopting the mechanical one-way valve, the automatic opening and closing of the valve can be realized without electric control, which is more convenient to use, and also has the function of preventing backflow, avoiding the liquid flowing back to the drainage tray 4.

[0047] In some embodiments, referring to Figure 3 The side wall plate 410 of the drainage tray 4 is gradually inclined outward from bottom to top, so that the cross-sectional area of the inner cavity of the drainage tray 4 gradually increases from bottom to top. On the one hand, it can effectively receive the liquid flowing out of the through hole 5 and avoid the liquid splashing to the ground. At the same time, the inclined design can also effectively buffer the flow of liquid and gas. The implementation of the buffering effect is as follows: for liquid, the inclined wall can slowly change the flow direction of the liquid under the impact of the liquid flow, gradually weaken the flow rate of the liquid, and avoid splashing of the liquid; for gas, the inclined design can also gradually weaken the flow rate of the gas to avoid the gas from splashing out of the exhaust gap 6 with the liquid.

[0048] Optionally, convex points in a preset array (for example, a rectangular array or a ring array) are arranged on the bottom wall plate 420 of the drainage tray 4. After the liquid flows into the drainage tray 4 and contacts the bottom wall plate 420, the convex points can disturb the flow of the liquid, further reducing the flow rate of the liquid.

[0049] Optionally, the bottom wall plate 420 is gradually inclined upward along the direction from the drainage channel to the side wall plate 410, so that the liquid flowing into the drainage tray 4 is guided by the bottom wall plate 420 and flows to the drainage channel spontaneously. The inclination angle of the bottom wall plate 420 relative to the horizontal plane is 10°-15°. By reasonably selecting the inclination angle, the effective guiding effect can be achieved, and the upper and lower dimensions of the drainage tray 4 can be reduced, so that the drainage tray 4 is more compact.

[0050] In some embodiments, referring to Figure 1 and Figure 2 , the mobile operation platform further comprises a support frame 8 arranged below the operation table 1 and connected with the plurality of supporting legs 2 respectively to limit the displacement of the supporting legs 2 in the direction perpendicular to the up-down direction, maintain the stability of the position of each supporting leg 2, avoid the inclination of the supporting legs 2 relative to the operation table 1, and maintain the structural stability of the whole operation platform.

[0051] Based on the above embodiments, referring to Figure 1 and Figure 2 , in order to facilitate operation, the operation table 1 is a rectangular member, and in order to effectively support the operation table 1, four supporting legs 2 are arranged at the four corners of the operation table 1. The support frame 8 comprises a support longitudinal rod 810 and two support transverse rods 820, the two support transverse rods 820 are arranged corresponding to the two short sides of the operation table 1 and are respectively supported and connected between the two supporting legs 2 on the corresponding side; the support longitudinal rod 810 is parallel to the long side of the operation table 1, and the two ends of the support longitudinal rod 810 are respectively connected between the two support longitudinal rods 810. The support frame 8 of the embodiment is in the shape of an I-beam, has a simple structure, and can provide stable support in the length direction and the width direction of the operation table 1 respectively, and has good use reliability.

[0052] In some embodiments, referring to Figures 1 to 4 , the operation table 1 comprises a frame 110 and a table body 120, the table body 120 is connected to the inner side of the frame 110, the supporting legs 2 are connected to the lower part of the frame 110, and the table body 120 is provided with the through hole 5. The frame 110 facilitates the installation of the table body 120 and the supporting legs 2, and can enhance the structural strength of the whole operation table 1 and prolong the service life of the mobile operation platform.

[0053] Optionally, referring to Figure 3 , the frame 110 is a hollow member made of stainless steel, has good corrosion resistance and high structural strength, and the weight of the frame 110 will not be too heavy, which is conducive to the weight reduction of the whole operation table 1 and facilitates the movement of the operation platform by the operator.

[0054] Based on the frame 110, referring to Figure 3The opposite sides below the frame 110 are respectively provided with slide rails 9, the slide rails 9 have C-shaped grooves, and the side portions of the drainage tray 4 are slidingly inserted into the C-shaped grooves of the slide rails 9. After being inserted, the drainage tray 4 can be effectively supported by the slide rails 9 and will not fall off. When the drainage tray 4 needs to be disassembled or assembled, the drainage tray 4 can be quickly disassembled or assembled by pulling, and the disassembly and assembly are more convenient.

[0055] In some specific embodiments of the slide rails 9, the slide rails 9 include a rail top plate 910, a rail side plate 920, a rail inclined plate 930 and a supporting plate 940. The rail top plate 910 is connected with the lower surface of the frame 110. The rail side plate 920 is arranged at the outer side edge of the rail top plate 910 and extends downward. The outer side edge of the rail inclined plate 930 is connected with the lower edge of the rail side plate 920, and the rail inclined plate 930 gradually inclines upward from the outside to the inside. The rail inclined plate 930 is provided with a leakage hole 950 at the intersection with the rail side plate 920. The supporting plate 940 is arranged at the inner edge of the rail inclined plate 930, and the plate surface is perpendicular to the up-down direction. The supporting plate 940 is arranged in the up-down direction with the rail top plate 910. The side portion of the drainage tray 4 is slidingly inserted into the space between the rail top plate 910 and the supporting plate 940, and the supporting plate 940 supports the bottom wall plate 420 of the drainage tray 4. The side wall plate 410 of the drainage tray 4 and the rail top plate 910 form an exhaust gap 6. When the slide rails 9 are cleaned after use, the disinfectant flowing into the slide rails 9 can flow to the leakage hole 950 under the guide action of the rail inclined plate 930 and finally flow out of the slide rails 9, so as to avoid the accumulation of disinfectant waste in the slide rails 9.

[0056] Optionally, the slide rails 9 further include a rail end plate arranged at one end of the rail top plate 910, so as to limit the insertion depth of the drainage tray 4 and avoid the drainage tray 4 from falling out of the slide rails 9 due to the excessive insertion depth.

[0057] In some embodiments, the table surface of the table body 120 is not higher than the upper end surface of the frame 110. Specifically, the table surface of the table body 120 is flush with the upper end surface of the frame 110 (as shown in Figure 1 ), which is more convenient for cleaning the table surface; or the table surface of the table body 120 is lower than the upper end surface of the frame 110 (as shown in Figure 2 and Figure 3 ), so as to avoid the liquid from flowing from the edge of the operation table 1 to the ground and avoid the pollution of the ground.

[0058] In some embodiments, referring to Figures 4 to 6 , the mobile operation platform further includes a handle 10, which is convenient for exerting force when moving and avoids the problem that the hands directly contact the operation table 1 to pollute the operation table 1. Based on this, the handle 10 is detachably connected to the frame 110. After being moved to the position, the handle 10 is detached, so as to avoid the handle 10 from knocking the operator when the operation platform is used to produce.

[0059] In some specific embodiments, referring toFigure 2 The side of the frame 110 is provided with a downwardly open slot 11, and the outer wall of the slot 11 is provided with a position-avoiding gap 12, the area of the position-avoiding gap 12 being smaller than the area of the side wall of the slot 11; the handle 10 comprises a handle body 1010 and a plug plate 1020, and the handle body 1010 is connected to one side plate surface of the plug plate 1020. When the handle 10 is needed to be used, the plug plate 1020 is inserted upward from the opening below the slot 11, and the plug plate 1020 is gap-fitted with the slot 11. Since the area of the position-avoiding gap 12 is smaller than the area of the side wall of the slot 11, and the area of the plug plate 1020 is greater than the area of the position-avoiding gap 12, the plug plate 1020 will not be pulled out from the side where the position-avoiding gap 12 is located after being inserted into the slot 11. Based on this, the position-avoiding gap 12 is arranged corresponding to the handle body 1010, and the handle body 1010 can exert an outward pulling force or an inward pushing force on the plug plate 1020, thereby pulling or pushing the operation platform.

[0060] Optionally, referring to Figure 6 The edge of the plug plate 1020 is provided with a first magnet 1030, and the top wall of the slot 11 is provided with a second magnet 13. After the plug plate 1020 is inserted, the first magnet 1030 and the second magnet 13 are magnetically attracted to each other, thereby preventing the plug plate 1020 from falling off. When the handle 10 needs to be disassembled, the handle body 1010 only needs to be pulled downward to overcome the magnetic attraction force between the first magnet 1030 and the second magnet 13, so that the plug plate 1020 can be pulled out.

[0061] In other ways in which the frame 110 and the handle 10 can be detachably connected, the handle comprises a handle body and a hook connected to each other, and the hook is hung on a hanging hole on the frame or on the through hole 5 to achieve the hanging connection of the handle and the operation platform 1. Based on this, an auxiliary hook is arranged on the supporting leg 2, and after the handle is separated from the operation platform 1, the hook thereon can be hung on the auxiliary hook to avoid the handle being placed randomly and lost.

[0062] In some embodiments, a brake device is arranged on the universal wheel 3. After being moved to a position, the posture of the universal wheel 3 is fixed by the brake device, and the operation platform cannot be moved any more, thereby avoiding the problem that the operation of the operation platform 1 affects the work during work. The brake device can refer to the existing brake structure of the universal wheel 3, and the specific structure will not be described in detail here.

[0063] The above only describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
