Description

Finger-stall type medical centrifugal tube cap opener

Technical Field

The utility model relates to a medical equipment technical field, in particular to medical centrifuging tube cap opener of finger cot.

Background

The centrifugal tube (EP tube) is a plastic centrifugal tube commonly used in the field of medical inspection and scientific research experiments, and is a small container commonly used for long-term storage, temporary storage and transportation or experimental transfer of reaction reagents or detected samples, such as blood, body fluid, reagents and the like, and the specification of the small container is 5ml, 2ml, 1.5ml and 200 ul. Of these, EP tubes of 1.5ml and 200ul sizes are the most common in the field of molecular experimentation. In the daily operation of a laboratory, the uncapping operation needs to be carried out for multiple times every day, each sample is extracted from nucleic acid to a common PCR amplification experiment, and the uncapping operation needs to be carried out for 20-50 times according to the complexity of the experimental flow. For laboratories with more than 100 specimen detection quantities per day, the uncapping times can reach thousands of times, even thousands of times. At present, the laboratory staff only manually uncover the bottom of the EP tube by using one hand, or the EP tube is placed at the fixed bottom of a special frame, and the other hand forcibly uncovers the EP tube from the protruding part of the EP tube cover by using the nail or the inner side part of the thumb. Repeated operation causes fatigue of thumb muscles of operators, even nail eversion, and skin abrasion of blisters or calluses, which damages the health of the operators.

The existing diversified EP pipe cap openers in the market at present mainly have a piece formula cap opener, cylindrical cap opener, the additional structure that uncaps of stack on the EP pipe cap etc. and the leading principle all is with lever method, reduces the experimenter and uses hard. Common sheet type cap openers and cylindrical cap openers are small and exquisite conveniently, production specifications are single, one cap opener is only suitable for one EP pipe, applicability is not wide enough, and in addition, one hand for opening the cap must hold the cap opener all the time, so that other operations cannot be flexibly performed; the overlapped cap opener is a part extending out of the EP pipe, and the EP pipes are required to be sleeved one by one when in use, so that the operation flow and steps are increased; the manual batch cap opener can open a plurality of EP tubes at one time, and the cap opener is easy to fly out reagents or samples in the tubes to generate aerosol, has the possibility of cross contamination and is not suitable for experiments with high biological safety requirements; in addition, an automatic mechanical uncapping device is generally attached to a sample processing device, is a part of a production line, cannot be matched with manual flexible operation, and is high in mechanical equipment manufacturing cost.
