Description

TECHNICAL FIELD

[0001] The utility model belongs to the production scale trace reagent freeze-dried ball partial shipment technical field relates to a reagent freeze-dried ball device is partial shipment to eight joint pipe. BACKGROUND

[0002] The micro-volume freeze-dried reagent product represented by the molecular detection reagent is usually provided in the form of freeze-dried small balls. In the manufacturing, the liquid reagent is separated by a fixed volume and operated at low temperature to obtain reagent frozen ice beads, and the batch-packed ice beads are vacuum dried to obtain batch freeze-dried small balls. The commercially available end product usually requires that the small balls are individually packed and stored in commonly used standard experimental eight-tube pipes for direct reconstitution and use. Therefore, during the production process, a large number of freeze-dried small balls need to be packed into the target type of eight-tube pipes under dry conditions, and the tube cover is tightly closed to realize dry and airtight packaging, meet the requirements of long-term storage and regular transportation. At present, the following methods are used to pack a large number of freeze-dried small balls into eight-tube pipes one by one:

[0003] 1) Direct manual packing. Ordinary tools such as tweezers, cotton swabs, etc. are used to pick up or move the freeze-dried small balls to make them enter the eight-tube pipes respectively. The operation efficiency of manually moving each small ball is extremely low, and the operation requires very high skills and stability of the operator's hands and eyes. The labor intensity and labor cost are very high. At the same time, this method is difficult to support the expansion of production scale and the continuous labor of skilled personnel. In addition, using hand-held tools to directly touch the small balls has a relatively high probability of mechanically damaging the small balls, even crushing them, causing product loss and operating environment pollution.

[0004] 2) Use negative pressure suction to move the small balls individually. Since the freeze-dried small balls are fluffy dry matter, not airtight solid, which is the physical form required by the reconstitution characteristics of the small balls. Light negative pressure has not enough adsorption force to hold the small balls; and the mechanical strength of the small balls is very limited, loose and fragile, only accepting very gentle operation, and high negative pressure suction is easy to damage the small balls. The size and strength of the vacuum area are very difficult to determine. This operation method is not much different from direct manual packing.

[0005] 3) Use positive pressure blowing to move the small balls. The small balls are fluffy dry matter, and the weight is very small, so it is difficult to control the local strength of the blowing to accurately and batch-operate the directional movement of the small balls.

[0006] 4) There are many automatic small ball dispensing equipment, including finished machine and in the design, are powered automated mechanical equipment, their dispensing efficiency is relatively high, but all have corresponding shortcomings, for example, an application number CN202221184120.8 utility model patent provides a freeze-dried reagent dispensing assembly, including: storage device, including a plurality of reagent container units, reagent container unit has a storage cavity, the storage cavity is used for storing freeze-dried reagent;Fixing frame for fixing the storage device;Groove plate is provided with a plurality of reagent grooves, each reagent groove is correspondingly arranged with each reagent container unit, and the size of the reagent groove is matched with the freeze-dried reagent. When dispensing, the freeze-dried reagent falls into each reagent groove, then the storage device is inverted on the groove plate, and each reagent container unit is aligned with each reagent groove in the groove plate, then the groove plate and the storage device are kept in abutment and the groove plate is turned over, finally the groove plate is vibrated, so that the freeze-dried reagent in the reagent groove falls into the corresponding reagent container unit, thereby the freeze-dried reagent is quickly dispensed into each reagent container unit. The similar prior art has completed the distribution of small balls into eight-pipe, but has not completed the closing of the pipe cover, the pressing of the pipe cover and the whole process of sealing and packaging, which is one of the key operation steps in the dispensing process, so there is a great improvement space.

[0020] Compared with the prior art, the reagent lyophilized ball device for eight-tube dispensing has the beneficial effects that:

[0021] 1. The guide plate can be moved to align the guide hole with the sieve hole, so that the freeze-dried ball can fall smoothly into the eight-piece tube to be replaced. Then, it can be misaligned to close. Then, the replacement can move along the horizontal groove to push the cover of the eight-piece tube to bend and cover it.

[0026] 6. The top plate is used to contact the bottom of the eight-piece tube. The top plate is located in the movable cavity and can be raised and lowered relative to the base, so that the user can manually lift it to remove the eight-piece tube after the entire process of disassembly and packaging is completed, without having to pry it out by hand.

[0027] 7. The movable cavity is located between the lower seat and the eight-tube seat and is connected to the receiving hole, which facilitates the quick installation and disassembly of the top plate, and also allows the user to directly observe the eight-tube from the outside.

[0028] 8. Freeze-dried spheres need to be packaged in a very dry environment. To maintain this environment, the glove box needs to be equipped with thick gloves with good sealing effect, which makes the operation inside the glove box extremely inconvenient. This device has a simple structure and is easy to operate, bringing convenience to the operator.

[0029] 9. The space inside the glove box is limited and completely sealed. This device is small in size, easy to enter and exit the glove box, and convenient to move and operate.

[0030] 10. The glove box is completely sealed. Complex machinery is prone to creating unsanitary corners. This device is all-metal, easy to disassemble and clean, and can effectively avoid the problem of secondary contamination inside the glove box.

[0031] 11. The eight-tube pack with cap is a common packaging carrier for lyophilized reagents.
