Description

Anti-blocking TIP head with air groove

Technical Field

The application relates to the field of pipetting instruments, in particular to an anti-blocking TIP head with an air groove.

Background

The suction head, namely the TIP head, is used for automatic or semi-automatic pipetting equipment, can store and pour out solution, can effectively form a protection structure between a pipettor and a sample in the medical experiment research process, and ensures the safety of sample suction and sample separation.

However, since the TIP of the TIP head of the present day does not have a piercing structure, the TIP head does not have a piercing function, and thus the TIP head is used in a generally open container for sucking or pouring a liquid. When liquid is required to be sucked or poured out of a container with a seal, the existing TIP is difficult to meet the requirement, and workers are required to remove the seal first to perform subsequent pipetting operations, particularly when hazardous liquid is pipetted, the workers are easily injured.

In addition, if the needle is simply combined with the TIP head, the TIP head can be provided with a piercing capability, but the following problems still remain: (1) The hole of the needle is easily blocked by the sealing material, which affects the normal use of the TIP head; (2) The bottom-most liquid is difficult to completely extract due to the bevel design of the needle; (3) As the liquid in the container is gradually withdrawn, the air pressure in the container is gradually reduced, so that the extraction of the residual liquid is affected, and even the TIP head can be detached from the device.

Example 1

As shown in fig. 1 and 2, an anti-blocking TIP with an air groove comprises a tube body 200, a sleeve head 100 arranged at the top of the tube body 200, a tube head 300 arranged at the lower end of the tube body 200, a puncture needle 400 arranged at the lower end of the tube head 300, and a cavity 500 which penetrates the sleeve head 100, the tube body 200 and the tube head 300 and is communicated with the puncture needle 400.

The body 200 and the tip 300 are tapered.

The sleeve head 100 is further provided with internal threads.

As shown in fig. 3, the puncture needle 400 is composed of a transition head 401, a needle body 402 provided at the lower end of the transition head 401, a needle cavity 403 provided in the needle body 402, and a needle port 404 provided at the bottom end of the needle body 402.

The transition piece 401 is integrally secured to the tube head 300.

In order to improve the integration of the product, the sleeve head, the pipe body, the pipe head and the puncture needle head of the product are made of the same material, so that the problem that the materials of different materials are mutually fixed and difficult is solved, and according to actual use requirements, the medical plastic can be selected for preparing the product, and the metal material can be selected for preparing the product.

The needle lumen 403 communicates with the lumen 500 after passing upwardly through the transition head 401.

The bottom end of the needle body 402 is circular arc shaped.

The needle opening 404 is inclined through the bottom end of the needle body 402.

In order to ensure that the product can suck all the liquid in the container when sucking the liquid, the position of the needle opening penetrating through the needle body needs to be ensured at the lowest part of the needle body.

And because the product is the vertical direction motion when using, so the slope sets up the required power when the needle mouth that can be very big improvement rubber gets into the needle mouth, and then can avoid the needle mouth to be blocked by rubber the biggest possible.

As shown in fig. 4, a vent slot 405 is also provided vertically on the outer side of the needle body 402.

The exhaust groove is arranged, so that the needle head main body can provide an air inlet channel for the inside of the container when penetrating the rubber plug, and further the balance of the air pressure inside and outside the container is ensured, and the normal absorption of liquid is ensured not to be influenced because the air pressure inside the container is reduced when the liquid is absorbed by the product.

It should be noted that all of the features disclosed in this specification, or all of the steps in a method or process disclosed, may be combined in any combination, except mutually exclusive features and/or steps.

In addition, the foregoing detailed description is exemplary, and those skilled in the art, having the benefit of this disclosure, may devise various arrangements that, although not explicitly described herein, are within the scope of the present disclosure. It should be understood by those skilled in the art that the present description and drawings are illustrative and not limiting to the claims. The scope of the utility model is defined by the claims and their equivalents.
