A bioreactor

Abstract

The application provides a bioreactor. The bioreactor comprises a glass reactor body, a baffle plate arranged at an upper opening of the glass reactor body, and a plurality of split handles arranged at a first end face of the baffle plate and away from the glass reactor body. The split handle comprises a handle base, a handle shaft and a handle handle. The handle handle is an L-shaped handle composed of a first handle section and a second handle section. The bottom of the handle base is fixed on the first end face through a connecting part. The handle base is also provided with a receiving cavity with an open top. The open top extends towards the direction of the edge of the first end face and forms a gap. One end of the first handle section of the handle handle is arranged in the receiving cavity and rotationally connected to the handle base through the handle shaft. The handle handle moves between a first position and a second position through rotation. The above scheme enables the handle to be adjusted in position as required, thereby avoiding the space interference problem caused by the traditional fixed handle during the operation of the reactor.

Description

Technical Field

[0001] This application relates to the technical field of experimental equipment, and more particularly to a bioreactor. Background Technology

[0002] Bioreactors are widely used as experimental equipment in fields such as biology, chemistry, and pharmaceuticals. Their main function is to provide a controlled environment for biochemical reactions, enabling efficient experimental operations and production processes.

[0003] However, existing bioreactors are designed with fixed handles. Due to the compact structure of (glass) bioreactors, these handles make operation inconvenient. Therefore, there is an urgent need for a different type of bioreactor. Utility Model Content

[0004] The purpose of this application is to provide a bioreactor that solves the above-mentioned technical problems.

[0005] The objective of this application is achieved through the following technical solution: This application provides a bioreactor, including a glass reactor body and a baffle disposed at the upper opening of the glass reactor body, and further including a plurality of split handles disposed at the first end face of the baffle away from the glass reactor body; the split handle includes a handle base, a handle shaft and a handle handle, and the handle handle is an L-shaped handle composed of a first handle section and a second handle section. The bottom of the handle base is fixed to the first end face via a connecting part. The handle base also has a receiving cavity with a top opening. The top opening extends toward the edge of the first end face and forms a notch. One end of the first section of the handle is disposed in the receiving cavity and is rotatably connected to the handle base via the handle pivot. The handle moves between a first position and a second position as it rotates. In the first position, the second section of the handle is parallel to the side of the baffle. In the second position, the second section of the handle is parallel to the first end face of the baffle.

[0006] In some optional embodiments, the accommodating cavity has two first through holes on its two sides near the notch, and the handle shaft passes through the two first through holes and is fixed to the handle base; one end of the first section of the handle handle has a second through hole, and is sleeved on the handle shaft through the second through hole, so that it is rotatably connected to the handle base.

[0007] In some alternative embodiments, the handle pivot is an internal hex screw that passes through the two first through holes and is threaded to the handle base.

[0008] In some alternative embodiments, the number of split handles is even, and the second handle segments of two adjacent split handles are connected at the ends away from the first end via a handle portion to form a split handle assembly structure.

[0009] In some alternative embodiments, each of the split handle assembly structures is evenly distributed along the outer ring of the first end face of the baffle.

[0010] In some optional embodiments, the handle portion, the first handle section, and the second handle section of the split handle assembly are all cylindrical structures.

[0011] In some alternative embodiments, the number of the split handles is 4, 6, or 8, and the number of the split handle assembly structures is 2, 3, or 6.

[0012] In some alternative embodiments, the outer surface of the handle portion is provided with a non-slip, heat-insulating sleeve.

[0013] In some optional embodiments, the connecting part is a bolt fixed to the first end face, the bottom of the handle base is provided with a threaded hole that matches the bolt, and the handle base and the first end face are fixedly connected by the connecting part through threads.

[0014] In some alternative embodiments, the length of the first handle segment is less than the length of the second handle segment.

[0015] Based on the above technical solutions and the technical problems solved, the technical solution to be protected in this application involves a split-type handle fixed to the first end face of an open baffle on the glass reactor body via a handle base. The bottom of the handle base is fixedly connected to the baffle via a connecting part (such as a bolt) to ensure the stability and firmness of the handle. The handle consists of a first section and a second section, forming an L-shaped structure. One end of the first section is placed in the receiving cavity of the handle base and is rotatably connected to the handle base via a handle pivot. The handle pivot allows the handle to rotate freely within the receiving cavity. During use, the user can switch between a first position and a second position by rotating the handle. In the first position, the second section of the handle is parallel to the side of the baffle. At this time, the handle is in a retracted state, which will not interfere with the operation of the reactor and is suitable for normal use of the reactor, avoiding the handle occupying space or affecting operation. In the second position, the second section of the handle is parallel to the first end face of the baffle. At this time, the handle is in an extended state, making it easy for the operator to hold for moving or transporting the reactor. This can be understood as follows: when the bioreactor needs to be moved, the operator will rotate the handle from the first position to the second position and grasp the handle to move it; when the bioreactor is in normal use, the handle will hang down naturally or be attached to the side of the baffle, without affecting the operation of the bioreactor. Therefore, the split handle design allows for repositioning the handle as needed, avoiding the spatial interference problems caused by traditional fixed handles during reactor operation. When the reactor is in normal use, the handle can be retracted, occupying no extra space and not affecting experimental operations; when transport is required, the handle can be quickly extended for easy handling by the operator, significantly improving the ease of operation of the bioreactor. Because the split handle can be retracted, it reduces the space occupied by the handle in the bioreactor operating area, making the overall structure of the bioreactor more compact and suitable for laboratory environments with limited space.

Detailed Implementation The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] This application provides a bioreactor, including a glass reactor body and a baffle disposed at the upper opening of the glass reactor body, and further including a plurality of split handles disposed at the first end face of the baffle away from the glass reactor body; the split handle includes a handle base, a handle shaft and a handle handle, and the handle handle is an L-shaped handle composed of a first handle section and a second handle section. The bottom of the handle base is fixed to the first end face via a connecting part. The handle base also has a receiving cavity with a top opening. The top opening extends toward the edge of the first end face and forms a notch. One end of the first section of the handle is disposed in the receiving cavity and is rotatably connected to the handle base via the handle pivot. The handle moves between a first position and a second position as it rotates. In the first position, the second section of the handle is parallel to the side of the baffle. In the second position, the second section of the handle is parallel to the first end face of the baffle.

[0021] The technical solution provided in this embodiment features a split handle fixed to the first end face of an open baffle on the glass reactor body via a handle base. The bottom of the handle base is fixedly connected to the baffle via a connecting part (such as a bolt), ensuring the stability and firmness of the handle. The handle consists of a first section and a second section, forming an L-shaped structure. One end of the first section is placed inside the receiving cavity of the handle base and is rotatably connected to the handle base via a handle pivot. The handle pivot allows the handle to rotate freely within the receiving cavity. During use, the user can switch between a first position and a second position by rotating the handle. In the first position, the second section of the handle is parallel to the side of the baffle. At this time, the handle is in a retracted state, which will not interfere with the operation of the reactor and is suitable for normal use of the reactor, avoiding the handle occupying space or affecting operation. In the second position, the second section of the handle is parallel to the first end face of the baffle. At this time, the handle is in an extended state, making it easy for the operator to hold for moving or transporting the reactor. This can be understood as follows: when the bioreactor needs to be moved, the operator will rotate the handle from the first position to the second position and grasp the handle to move it; when the bioreactor is in normal use, the handle will hang down naturally or be attached to the side of the baffle, without affecting the operation of the bioreactor. Its beneficial effects include the ability of the detachable handle to be adjusted in position as needed, avoiding the spatial interference problems caused by traditional fixed handles during reactor operation. When the reactor is in normal use, the handle can be retracted, taking up no extra space and not affecting experimental operations; when transport is required, the handle can be quickly extended for easy handling by the operator, significantly improving the ease of operation of the bioreactor. Because the detachable handle reduces the space it occupies in the bioreactor's operating area, the overall structure of the bioreactor is more compact and more suitable for laboratory environments with limited space.

[0022] In some embodiments, the accommodating cavity has two first through holes on its two sides near the notch, and the handle shaft passes through the two first through holes and is fixed to the handle base; one end of the first section of the handle handle has a second through hole, and is sleeved on the handle shaft through the second through hole, so that it is rotatably connected to the handle base.

[0023] This can be understood as follows: the accommodating cavity of the handle base has two first through holes on its two sides near the notch, which are used to install the handle shaft. The handle shaft passes through the two first through holes on the handle base and is fixed to the handle base by threads or other fixing methods (such as welding or riveting), ensuring the stability and firmness of the shaft. One end of the first section of the handle handle has a second through hole, which matches the diameter of the handle shaft. The handle handle is sleeved on the handle shaft through the second through hole, thereby realizing the rotatable connection between the handle handle and the handle base, allowing the handle handle to switch between two positions (such as the first position and the second position), thus realizing the retracting and unfolding function of the handle handle.

[0024] Therefore, by setting the first through hole on the handle base and using the handle shaft to pass through these through holes and fix it to the base, the structural design ensures the stability of the handle shaft and avoids the risk of the handle handle not turning smoothly or falling off due to the loose handle shaft.

[0025] As an example, the handle pivot is a hex socket screw that passes through the two first through holes and is threaded to the handle base.

[0026] In some embodiments, the number of split handles is even, and the second handle segments of two adjacent split handles are connected at the ends away from the first end via a handle portion to form a split handle assembly structure.

[0027] The number of split handles is even (e.g., 4, 6, or 8). These handles are evenly distributed on the first end face of the glass reactor's baffle, ensuring a symmetrical distribution that facilitates the operator's gripping and handling of the reactor from different directions. Simultaneously, the second sections of adjacent split handles are connected via a handle section, forming a single unit. This allows the operator to grip the reactor simultaneously via the handle section, providing a more stable grip and a more even force distribution, making it easier to handle heavier or larger reactors.

[0028] In some embodiments, each of the split handle assembly structures is evenly distributed along the outer ring of the first end face of the baffle.

[0029] The split handle assembly structure is evenly distributed along the outer ring of the first end face, that is, the handle assembly structure is set on the outer ring part of the first end face and arranged at equal intervals.

[0030] In some embodiments, the handle portion, the first handle section, and the second handle section of the split handle assembly are all cylindrical structures. Cylindrical structures have uniform cross-sectional characteristics, enabling even stress distribution and reducing localized stress concentrations. This allows them to remain stable under load, reducing the risk of deformation or damage. Simultaneously, the cylindrical handle portion provides a comfortable grip.

[0031] As an example, the number of separate handles is 4, 6, or 8, and the number of separate handle assembly structures is 2, 3, or 6. The outer surface of the handle portion is provided with a non-slip, heat-insulating sleeve. The non-slip, heat-insulating sleeve increases the friction between the handle portion and the hand, ensuring that the operator can firmly grip the handle even in wet or oily environments, reducing safety accidents caused by slippage.

[0032] In some embodiments, the connecting part is a bolt fixed to the first end face, and the bottom of the handle base is provided with a threaded hole that matches the bolt. The handle base and the first end face are threadedly connected through the connecting part. By using a threaded connection method of bolt and threaded hole to fix the handle base to the first end face of the glass reactor baffle, not only is the connection stability and structural strength improved, but installation, disassembly and maintenance are also facilitated.

[0033] In some implementations, the length of the first handle segment is less than the length of the second handle segment.

[0034] The first handle section connects the handle base to the second handle section. Its relatively short length reduces the space occupied during rotation. The longer second handle section facilitates the operator's application of force.

[0035] See Figure 1 and Figure 2 As an example, a bioreactor is provided to address the situation where the compact structure of the glass bioreactor makes operation inconvenient due to the handle.

[0036] The bioreactor provided in this example includes a glass reactor body 100 and a baffle 200 disposed at the upper opening of the glass reactor body 100. The baffle 200 is connected to the glass reactor body 100 by an O-ring. It also includes several split handles 300 disposed on the first end face of the baffle 200 away from the glass reactor body 100. Each split handle 300 includes a handle base 310, a handle pivot 320, and a handle 330. The handle 330 is an L-shaped handle composed of a first handle segment 331 and a second handle segment 332. The length of the first handle segment 331 is shorter than the length of the second handle segment 332. All parts of the handle (except for the anti-slip heat insulation sleeve) are made of 304 stainless steel.

[0037] The handle base 310 also has a receiving cavity 311 with a top opening, which extends toward the edge of the first end face and forms a notch. The receiving cavity 311 has two first through holes on its two sides near the notch. The handle shaft 320 is an internal hex screw, which passes through the two first through holes and is fixed to the handle base 310 by threads. The first section handle 331 of the handle handle 330 has a second through hole at one end, and is sleeved on the handle shaft 320 through the second through hole, so that it is rotatably connected to the handle base 310.

[0038] The number of split handles 300 is even. The ends of the second handle segments 332 of two adjacent split handles 300, away from the first end, are connected by a handle portion 340 to form a split handle assembly structure. Each split handle assembly structure is evenly distributed along the outer ring of the first end face of the baffle 200. The handle portion 340, the first handle segment 331, and the second handle segment 332 of the split handle assembly structure are all cylindrical structures. There are two split handle assembly structures, each evenly distributed along the outer ring of the first end face of the baffle 200.

[0039] In use, the handle base 310 is threaded onto the baffle 200 of the bioreactor. The handle 330 is connected to the handle base 310 via the handle pivot 320 using an Allen wrench. After installation, the handle 340 is lifted to use the equipment when needed, and when not in use, the handle hangs naturally to the sides of the equipment, thus not affecting the operation of the reactor.
