Technical Field

[0001] The utility model relates to the field of cell culture, in particular to a soft film sealing chamber which can be operated by bare hands. Background Art

[0002] When cultivating cells, microorganisms, etc., it is usually necessary to use a soft film sealed chamber. The soft film sealed chamber is a special device for cultivating and operating cells, microorganisms, etc. under a preset environment (anaerobic, hypoxic or other gas environment). In order to keep the environment in the soft film sealed chamber relatively stable, the existing technology usually chooses to operate through the chamber wall of the soft film sealed chamber, which will result in extremely low precision in the entire operation process and increase the difficulty of operation. If a robotic arm is used for operation, the volume of the entire soft film sealed chamber will be significantly increased, the cost of the soft film sealed chamber will be significantly increased, and the cultivation process will be more uncontrollable. Therefore, there is an increasing demand in the market for soft film sealed chambers that can be operated with bare hands. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model discloses a soft film sealing chamber which can be operated by bare hands.

[0004] A soft film sealed warehouse that can be operated with bare hands comprises a warehouse body, wherein the warehouse body is connected with an air pump, the warehouse body is provided with a plurality of bare hand channels, the bare hand channels comprise a soft film sleeve extending from the outer wall of the warehouse body toward the inner part of the warehouse body, the outer wall of the warehouse body is provided with a avoidance opening for avoiding the bare hand channels, the end of the soft film sleeve away from the avoidance opening is provided with a warehouse body entrance, a sealing plug is detachably connected to the warehouse body entrance, an end of the soft film sleeve close to the warehouse body entrance is detachably connected to an elastic sealing wrist, the elastic sealing wrist is provided with a avoidance hole for a hand to pass through, and the sealing plug is partially located in the avoidance hole of the elastic sealing wrist.

[0005] Specifically, first turn on the inflation pump to fill the gas into the warehouse body, at this time one of the warehouse body entrances can be opened, and after the concentration of the gas component in the warehouse body reaches a preset range, the warehouse body entrance can be closed; when it is necessary to enter the soft film sealed warehouse with bare hands to operate, the hand (latex, nitrile gloves, etc. can also be worn according to the supply and demand of the specific operation) enters the soft film sleeve from the avoidance port, and then passes through the elastic sealing wrist provided in the soft film sleeve. When the hand contacts the sealing plug located in the avoidance hole of the elastic sealing wrist, force is applied to the sealing plug to remove the sealing plug from the warehouse body entrance, and then the hand and the sealing plug enter the warehouse body together. After placing the sealing plug in a suitable position in the warehouse body, the operation can be performed in the warehouse body. After the operation is completed, the sealing plug is picked up and moved in the reverse direction along the path of entering the warehouse body to exit the warehouse body. In the process of exiting the warehouse body, the sealing plug needs to be connected to the warehouse body entrance again;

[0006] When passing through the elastic sealing wrist, the palm first stretches the elastic sealing wrist, and after the palm passes through, one end of the elastic sealing wrist tightens the wrist, thereby achieving a seal between the elastic sealing wrist and the wrist. Therefore, when the sealing plug is opened to enter the soft film sealing chamber, only a very small amount of gas will be brought in, and the gas inside the soft film sealing chamber is always in a state of dynamic circulation adjustment, and the very small amount of gas brought in will not cause any adverse effect on the culture environment in the soft film sealing chamber.

[0010] The plug body includes a plurality of limiting members, and the sealing ring is provided with a clamping groove for cooperating with the limiting members to fix the relative position between the sealing plug and the warehouse body entrance.

[0011] Specifically, since the plug body and the warehouse entrance need to be frequently disassembled and assembled, it is appropriate to provide a limit piece and a slot structure to facilitate the disassembly and assembly between the plug body and the warehouse entrance.

[0012] Preferably, each of the limiting members protrudes outwardly along the radial direction of the plug body, and the locking or releasing of the locking member with the locking slot is achieved by rotating the plug body.

[0013] Specifically, when the sealing plug is withdrawn from the warehouse body with the hand and the sealing plug needs to be connected to the warehouse body entrance, due to the limitations of viewing angle, operating space, and freedom of movement, if a latch-type slot and limiter structure is used, alignment problems will occur, thereby increasing the difficulty of installing the sealing plug and the warehouse body entrance. However, the structure provided by the utility model only requires rotating the sealing plug until the limiter is inserted into the slot, which is convenient, fast, and stable to install.

[0014] Preferably, the sealing plug further comprises a hand support bracket, the hand support bracket is used to prop open the elastic sealing wrist, and the hand support bracket and the handle are arranged on the same side of the plug body.

[0015] Specifically, the elastic sealing wrist is made of a flexible material, so it is difficult to maintain its own shape. Therefore, it is necessary to use the structure of the palm support bracket to help the elastic sealing wrist maintain its own shape to facilitate the movement of the palm.

[0016] Preferably, the elastic sealing arm includes an insertion portion and a fixed portion which are integrally connected, the fixed portion is arranged close to the warehouse entrance, and the insertion portion is arranged close to the avoidance opening, the radial dimension of the insertion portion gradually decreases in the direction away from the warehouse entrance, and the minimum diameter of the insertion portion is 25-52mm.

According to the statistical data of the diameter of human wrists, it is appropriate to set the smallest diameter of the insertion part to be between 25-52 mm. Most preferably, the diameter of the insertion part is set to be 37-39 mm, which is suitable for the wrists of most Asians.

[0018] In addition, the elastic sealing wrist is designed to have a structure in which the fixed part and the extending part are integrally connected, which can not only achieve sealing between the elastic sealing wrist and the wrist but also ensure that the palm can move freely in the elastic sealing wrist.

[0019] Preferably, the elastic sealing wrist is a silicone sealing wrist.

[0020] Preferably, the radial dimension of the soft film sleeve gradually decreases from the avoidance opening to the warehouse entrance, and the minimum dimension of the soft film sleeve is matched with the maximum dimension of the elastic sealing wrist.

[0021] Preferably, the warehouse body is provided with at least one visible surface, and the visible surface is made of transparent material.

[0022] Specifically, since the hand needs to enter the warehouse body to operate, it is necessary to provide a structure with a visual surface so that the operator can directly obtain the internal conditions of the warehouse body by vision.

[0023] Preferably, a plurality of soft film supports are provided on the top and / or side walls of the warehouse body, and the soft film supports are detachably connected to the warehouse body.

[0024] Specifically, the entire warehouse body is made of a flexible soft film. If the soft film is to be inflated to form a relatively regular shape (more stable and easier to operate), a soft film bracket is required to provide support for the warehouse body.

[0025] Compared with the prior art, the utility model is beneficial in that:

[0026] A plurality of bare-hand passage structures are arranged in the warehouse body for bare hands to pass through, and a sealing plug detachably connected to the warehouse body entrance is used to allow the hand to enter the warehouse body, and the warehouse body entrance can also be closed by the sealing plug when exiting the warehouse body. The structure of the soft film cuff and the elastic sealing plug ensures that on the one hand very little gas is brought into the warehouse body when the hand enters the warehouse body, and on the other hand ensures that the warehouse body is still isolated from the external environment after the hand enters the warehouse body. That is, this structure realizes the delicate operation of bare hands entering and exiting the warehouse body, and at the same time ensures that the culture environment in the warehouse body is always in a dynamic balance.

[0031] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figure 1-4 As shown, the soft film sealed chamber can be operated with bare hands ( Figure 1 The warehouse body 10 is made of transparent material), including a warehouse body 10, which is connected to the inflation pump, and is provided with a plurality of bare-hand channels. The bare-hand channels include a soft film sleeve 20 extending from the outer wall of the warehouse body 10 toward the inside of the warehouse body 10, and a avoidance opening for avoiding the bare-hand channels is provided on the outer wall of the warehouse body 10. A warehouse body entrance 21 is provided at one end of the soft film sleeve 20 away from the avoidance opening, and a sealing plug is detachably connected to the warehouse body entrance 21. An elastic sealing wrist 40 is detachably connected to one end of the soft film sleeve 20 close to the warehouse body entrance 21, and the elastic sealing wrist 40 is provided with an avoidance hole 41 for a hand to pass through, and a sealing plug portion is located in the avoidance hole 41 of the elastic sealing wrist 40.

[0033] The sealing plug includes a detachably connected plug body and a handle 32 . The plug body is detachably connected to the warehouse inlet 21 . When the plug body is connected to the warehouse inlet 21 , the handle 32 is located in the avoidance hole 41 of the elastic sealing arm 40 .

[0034] In this structure, the sealing plug can be removed from the warehouse entrance 21 by holding the handle 32 and applying force, and the structural forms on both sides of the plug body are obviously different, which is more convenient when the hand is carrying the sealing plug out from the interior of the warehouse 10.

[0035] The plug body includes a main body 31 and a sealing member 33. The inlet 21 of the silo is connected with a sealing ring 34 that cooperates with the sealing member 33, and the sealing ring 34 is located inside the silo 10.

[0036] The plug body includes a plurality of limiting members 35 , and the sealing ring 34 is provided with a clamping groove 36 for cooperating with the limiting members 35 to fix the relative position between the sealing plug and the warehouse inlet 21 .

[0037] Since the plug body and the warehouse inlet 21 need to be frequently assembled and disassembled, it is appropriate to provide a structure of a limiter 35 and a slot 36 to facilitate the assembly and disassembly of the plug body and the warehouse inlet 21 .

[0038] Each stopper 35 protrudes outwardly along the radial direction of the plug body, and the stopper 35 is engaged or released with the engaging groove 36 by rotating the plug body.

[0039] When the hand is withdrawn from the warehouse body 10 with the sealing plug and it is necessary to connect the sealing plug and the warehouse body entrance 21, due to the limitations of viewing angle, operating space, and freedom of movement, it will be difficult to align if a latch-type snap-in structure is used, thereby increasing the difficulty of installing the sealing plug and the warehouse body entrance 21. The structure provided in this embodiment only requires rotating the sealing plug until the limit piece 35 is snapped into the slot 36, which is convenient, fast, and stable to install.

[0040] The sealing plug further comprises a hand support bracket 37, which is used to prop open the elastic sealing wrist 40, and the hand support bracket 37 and the handle 32 are arranged on the same side of the plug body.

[0041] The elastic sealing wrist 40 is made of a flexible material, so it is difficult to maintain its own shape. Therefore, it is necessary to use the structure of the palm support bracket 37 to help the elastic sealing wrist 40 maintain its own shape to facilitate the movement of the palm.

[0042] The elastic sealing arm 40 includes an integrally connected insertion portion 42 and a fixed portion 43. The fixed portion 43 is arranged close to the warehouse entrance 21 and the insertion portion 42 is arranged close to the avoidance port. The radial dimension of the insertion portion 42 gradually decreases in the direction away from the warehouse entrance 21. The minimum diameter of the insertion portion 42 is 25-52mm.

[0043] The part with the smallest diameter of the insertion part 42 is the part where the elastic sealing wrist 40 is tightened with the wrist. The elastic sealing wrist 40 of various sizes can be designed according to actual conditions (for example, according to gender and / or height and / or weight). The user can select the elastic sealing wrist 40 of a suitable size for operation according to his or her actual conditions. According to the statistical data of the diameter of the human wrist, it is appropriate to set the smallest diameter of the insertion part 42 to between 25 and 52 mm. Most preferably, the diameter of the insertion part 42 is set to between 37 and 39 mm, which is suitable for the wrists of most Asians.

[0044] In addition, the elastic sealing wrist 40 is designed to have a structure in which the fixing portion 43 and the extending portion 42 are integrally connected, which can not only achieve sealing between the elastic sealing wrist 40 and the wrist but also ensure that the palm can move freely inside the elastic sealing wrist 40 .

[0045] The elastic sealing wrist 40 is a silicone sealing wrist.

[0046] The radial dimension of the soft film sleeve 20 gradually decreases from the avoidance opening to the warehouse entrance 21 , and the minimum dimension of the soft film sleeve 20 is adapted to the maximum dimension of the elastic sealing wrist 40 .

[0047] The warehouse body 10 is provided with at least one visible surface, and the visible surface is made of transparent material.

[0048] Since the hand needs to enter the warehouse body 10 to operate, it is necessary to provide a structure with a visible surface so that the operator can directly obtain the internal conditions of the warehouse body 10 by vision.

[0049] A plurality of soft film supports 50 are provided on the top and / or side walls of the bin body 10 .

[0050] The warehouse body 10 is made of a flexible soft film as a whole. If the soft film is to be inflated into a regular shape (more stable and easier to operate), a soft film bracket 50 is required to provide support for the warehouse body 10. The soft film bracket 50 is detachably connected to the warehouse body 10.

[0051] When in use, first turn on the air pump to fill the gas into the warehouse body 10. At this time, one of the warehouse body entrances 21 can be opened. After the concentration of the gas component in the warehouse body 10 reaches a preset range, the warehouse body entrance 21 can be closed. When it is necessary to enter the soft film sealed warehouse with bare hands to operate, the hand (latex, nitrile gloves, etc. can also be worn according to the supply and demand of the specific operation) enters the soft film sleeve 20 from the avoidance port, and then passes through the elastic sealing wrist 40 provided in the soft film sleeve 20. When the hand touches the sealing plug in the avoidance hole 41 of the elastic sealing wrist 40, force is applied to the sealing plug to remove the sealing plug from the warehouse body entrance 21, and then the hand and the sealing plug enter the interior of the warehouse body 10 together. After placing the sealing plug in a suitable position in the warehouse body 10, the operation can be performed in the warehouse body 10. After the operation is completed, the sealing plug is picked up and moved in the reverse direction along the path of entering the warehouse body 10 to exit the warehouse body 10. In the process of exiting the warehouse body 10, the sealing plug needs to be connected to the warehouse body entrance 21 again;

[0052] When passing through the elastic sealing wrist 40, the palm first stretches the elastic sealing wrist 40, and after the palm passes through, one end of the elastic sealing wrist 40 tightens the wrist, thereby achieving a seal between the elastic sealing wrist 40 and the wrist. Therefore, when the sealing plug is opened and the soft membrane sealing chamber is entered, only a very small amount of gas will be brought in, and the gas inside the soft membrane sealing chamber is always in a state of dynamic circulation adjustment, and the very small amount of gas brought in will not cause any adverse effect on the culture environment in the soft membrane sealing chamber.
