Description

Technical Field

[0001] This utility model relates to the field of aseptic sampling technology in the production of biological products, and in particular to an auxiliary device for extracting liquid from large-capacity Schott bottles. Background Technology

[0002] The production of biological product bulk solutions requires a sterile environment. In the production of human lyophilized rabies vaccine (human diploid cell) bulk solution, liquid sampling is frequently performed using pipettes in 10L Schott flasks to complete related production operations such as control cell sampling. During liquid sampling, the pipette must not touch the Schott flask; any sample in the pipette that comes into contact with the flask will be discarded, increasing the difficulty of sampling. Especially in laminar flow hoods or biosafety cabinets, operators must wear disposable sterile gloves, and sterile glass plates separate the operator from the Schott flask for sampling. Due to the height of the Schott flask and the length of the pipette, operators cannot insert the pipette vertically into the flask; the flask must be tilted before insertion. However, the weight of a 10L Schott flask makes it impossible for the operator to maintain an inclined position for extended periods. Even slight shaking poses a risk of the pipette touching the flask, potentially damaging the flask and further increasing the difficulty of sampling.

[0003] To address the aforementioned issues, a device is needed to stably support the tilted Schott flask, ensuring stability during the sampling process and thereby improving sampling efficiency. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an auxiliary device for liquid extraction from large-capacity Schott bottles. This device can keep the Schott bottle in a stable state at multiple different angles, which helps to improve sampling efficiency.

[0005] This utility model is achieved through the following technical solution: an auxiliary device for dispensing liquid from large-capacity Schott bottles, characterized in that: it includes a base; support rods and arc-shaped hanging walls are symmetrically arranged on the left and right sides of the base; a swing assembly is rotatably and swaying between the support rods, the swing assembly including a base support, a retaining plate fixedly arranged at the bottom of the base support, swing rods fixedly arranged on the left and right sides of the base support, and an annular support fixedly arranged between the swing rods; a rotating shaft is fixedly arranged on the top outer side of the swing rod, the rotating shaft being rotatably connected to a bearing arranged at the top of the support rod; the arc-shaped hanging wall is provided with an inner arc-shaped structure, the arc trajectory of the inner arc-shaped structure corresponding to the trajectory of the swing assembly swinging backward; the inner arc-shaped structure of the arc-shaped hanging wall is provided with grooves at intervals; a locking rod is engaged in the grooves.

[0006] Furthermore, a baffle is also provided on the base to limit the forward swing of the rocking assembly.

[0007] Furthermore, the base is provided with a groove that matches the shape of the bottom of the Schott bottle.

[0008] Furthermore, the number of the grooves is three.

[0009] The beneficial effects and features of this utility model are as follows:

[0010] This invention allows for flexible adjustment of the tilt angle of Schott flasks by inserting a positioning rod into different slots. Compared to existing technologies where operators need to manually support the flasks, this significantly improves the stability of the flasks when tilted. This design effectively avoids the risk of the pipette contacting the flask wall due to hand tremors or prolonged support, thus reducing the possibility of sample failure. Simultaneously, the ease of operation improves the efficiency of liquid sampling. Furthermore, this design reduces the difficulty of operation and lightens the workload of the operator.

Detailed Implementation

[0015] The following combination Figure 1-2 The contents of this utility model will be described in detail through specific embodiments. Example

[0016] This auxiliary device for dispensing liquid from large-capacity Schott bottles is made entirely of stainless steel for sterilization and cleaning. It includes: a base 1; symmetrically arranged support rods 101 and arc-shaped hanging walls 102 on the left and right sides of the base; a swaying assembly between the support rods, comprising a base 2, a retaining plate 203 fixedly mounted at the bottom of the base, swing rods 201 fixedly mounted on the left and right sides of the base, and an annular support 202 fixedly mounted between the swing rods; a rotating shaft fixedly mounted on the top outer side of the swing rods, rotatably connected to a bearing mounted on the top of the support rods; an inner arc-shaped structure on the arc-shaped hanging wall, the arc trajectory of which corresponds to the backward swing trajectory of the swaying assembly; and grooves spaced apart on the inner arc structure of the arc-shaped hanging wall, with locking rods engaged within these grooves.

[0017] Preferably, a baffle is also provided on the base to limit the forward swing of the rocking assembly.

[0018] To enhance the stability of the Schott bottle, a groove matching the shape of the bottle's bottom is provided on the base.

[0019] In order for the swing assembly to be fixed at three different angles after swinging, the number of hooks is three.

[0020] Base 1: As the basic support component of the entire device, the base is equipped with two symmetrically distributed support rods 101 and an arc-shaped hanging wall 102. The arc-shaped hanging wall has an inner arc-shaped structure, the arc trajectory of which matches the trajectory of the swing component swinging backward.

[0021] The swing assembly includes a base 2, a retaining plate 203 fixed to the bottom of the base, swing rods 201 fixed to the left and right sides of the base, and an annular support 202 connecting the swing rods. A pivot is fixed to the outer top of the swing rod, and the pivot is connected to the top of the support rod through a bearing, thereby enabling the swing assembly to swing between the support rods.

[0022] Positioning rod 3: Used to fix the position of the swing assembly. Three slots 103 are spaced apart on the inner arc structure of the curved wall mount, each slot corresponding to a fixed angle. Inserting the positioning rod into the appropriate slot achieves stable fixation of the swing assembly.

[0023] The operation steps of this utility model are as follows:

[0024] Place the Schott bottle containing the liquid to be collected on the base, ensuring that the bottom of the bottle is embedded in the groove on the base to increase stability.

[0025] Push the swing assembly backward to the desired tilt angle so that the Schott bottle opening tilts forward.

[0026] Select a slot according to actual needs, insert the locking bar into the slot and cooperate with the locking plate to complete the fixation of the swing component.

[0027] In a laminar flow hood or biosafety cabinet, operators perform liquid sampling using pipettes.
