Background technology

nullCheck in health care、In the experiment detection operating process such as life sciences，Centrifuge can be frequently used liquid sample is centrifuged operation，The supporting liquid sample carrier of centrifuge is usually test tube，The size of common test tube mostly is: φ 12mm × 70mm、φ15mm×150mm，Test tube opening is less as can be seen here，Use liquid-transfering gun liquid-transfering gun or dropper can be occurred unavoidably accidentally to encounter inboard wall of test tube when carrying out application of sample operation especially with dropper to transfer liquid in test tube，Or liquid is dropped in inboard wall of test tube，Especially near test tube mouth，Once remain sample liquid near test tube mouth，In the process using centrifuge to be centrifuged，Liquid near test tube mouth usually sputters test tube，Cause the loss of liquid sample，Moreover，It is also possible to pollute other test tube samples，Even pollute centrifuge，Even if using test tube with cover，Residual liquid is often had at test tube cap and test tube mouth in conjunction with gap place after centrifugal，Operator's glove are usually easily polluted when operator turn on test tube cap，And operator is easily caused the cross-contamination of different sample when carrying out the operation of large sample amount.

Summary of the invention

The purpose of this utility model is in that to solve problems of the prior art, it is provided that a kind of liquid being able to ensure that application of sample is completely into bottom test tube, it is prevented that liquid residue is at test tube mouth edge, it is to avoid cause the auxiliary liquid adding device of cross-contamination and secondary pollution.

This utility model is achieved in that a kind of auxiliary liquid adding device, it is characterized in that: include the first taper cone barrel transition conduit being sequentially connected from top to bottom, first pipe, second taper cone barrel transition conduit, second pipe, 3rd taper cone barrel transition conduit, 3rd pipe, 4th taper cone barrel transition conduit, 4th pipe, the external diameter of described second pipe is less than the external diameter of described first pipe, the external diameter of described 3rd pipe is less than the external diameter of described second pipe, the external diameter of described 4th pipe is less than the external diameter of described 3rd pipe, the outwards top turnover of the sidewall of the bottom of described 4th pipe forms gear edge, the top side of described first taper cone barrel transition conduit is provided with to be held by ear；Described first taper cone barrel transition conduit, the second taper cone barrel transition conduit, the 3rd taper cone barrel transition conduit, the 4th taper cone barrel transition conduit are the end opening bore circular cone tubular less than bore suitable for reading respectively.

The external diameter of described first pipe is 18 ~ 19mm, and the external diameter of described second pipe is 16 ~ 17mm, and the external diameter of described 3rd pipe is 13 ~ 14mm, and the external diameter of described 4th pipe is 9 ~ 10mm.

Described gear is 11 ~ 12mm along the maximum gauge in outside.

The bore suitable for reading of described first taper cone barrel transition conduit is 34 ~ 35mm.

The beneficial effects of the utility model are: by different size of first pipe, the second pipe, the 3rd pipe, the 4th pipe, the test tube of this utility model coupling Multiple Type specification can be made, the gear edge of described 4th pipe bottom not only can increase the adhesive force with test tube wall, and the 4th pipe bottom lowest order and inboard wall of test tube can be made to leave space, the liquid contact inboard wall of test tube remaining in this utility model can be avoided；Guarantee that the liquid of application of sample is completely into bottom test tube, it is prevented that liquid residue is at test tube mouth edge, it is to avoid cause the auxiliary liquid adding device of cross-contamination and secondary pollution.

Detailed description of the invention

According to Fig. 1, this utility model includes the first taper cone barrel transition conduit 1 being sequentially connected from top to bottom, first pipe 2, second taper cone barrel transition conduit 3, second pipe 4, 3rd taper cone barrel transition conduit 5, 3rd pipe 6, 4th taper cone barrel transition conduit 7, 4th pipe 8, the external diameter of described second pipe 4 is less than the external diameter of described first pipe 2, the external diameter of described 3rd pipe 6 is less than the external diameter of described second pipe 4, the external diameter of described 4th pipe 8 is less than the external diameter of described 3rd pipe 6, the outwards top turnover of the sidewall of the bottom of described 4th pipe 8 forms gear along 9, the top side of described first taper cone barrel transition conduit 1 is provided with to be held by ear 10；Described first taper cone barrel transition conduit the 1, second taper cone barrel transition conduit the 3, the 3rd taper cone barrel transition conduit the 5, the 4th taper cone barrel transition conduit 7 is the end opening bore circular cone tubular less than bore suitable for reading respectively.The external diameter of described first pipe 2 is 18 ~ 19mm, it is preferable that 19mm；The external diameter of described second pipe 4 is 16 ~ 17mm, it is preferable that 17mm；The external diameter of described 3rd pipe 6 is 13 ~ 14mm, it is preferable that 14mm；The external diameter of described 4th pipe 8 is 9 ~ 10mm, it is preferable that 10mm.Described gear is 11 ~ 12mm along the maximum gauge outside 9.The bore suitable for reading of described first taper cone barrel transition conduit 1 is 34 ~ 35mm.

When this utility model uses, before carrying out shifting liquid application of sample, first this utility model is entered test tube through test tube muzzle, hold liquid-transfering gun again or dropper carries out application of sample operation, it is the end opening bore circular cone tubular less than bore suitable for reading respectively due to described first taper cone barrel transition conduit the 1, second taper cone barrel transition conduit the 3, the 3rd taper cone barrel transition conduit the 5, the 4th taper cone barrel transition conduit 7, formed and multiple gather inclined-plane, precision when therefore can reduce liquid-transfering gun mouth or dropper mouth alignment test tube mouth in operator's application of sample process, stability requirement；And by first pipe the 2, second pipe the 4, the 3rd pipe the 6, the 4th pipe 8, the test tube of Multiple Type specification can be mated.The gear of described 4th pipe 8 bottom not only can increase the adhesive force with test tube wall along 9, and the 4th pipe 8 bottom lowest order and inboard wall of test tube can be made to leave space, can avoid the liquid contact inboard wall of test tube remaining in this utility model.
