Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] as attached figure 1 , 2 The improved structure of a cryogenic tube cap shown in . The outer diameter of the part 12, the top of the hand-twist part 11 is provided with an identification sticker groove 111, and a plurality of axial ribs 112 are provided on the side. The screw cap part 12 includes an outer protective body 121 and an inner tightening body 122. A tubular body cavity 123 is formed between the outer protecting body 121 and the inner tightening body 122. The inner tightening body 122 is removed from the lower surface, and the inner tightening body 122 is a tubular body. Form a pipetting chamber 125; the outer ring of the inner screw body 122 is provided with an external thread 1221, and the nozzle of the tube body 2 is provided with an internal thread 21 adapted to the external thread 1221, and the internal thread 21 is an i...

Abstract

The invention belongs to the field of medical devices, particularly to an improved structure of a freeze pipe cover. The improved structure of the freeze pipe cover comprises a cover body and a pipe body, wherein the cover body is composed of a twisting unit and a screw unit, and the screw unit comprises an outer protector and an inner screwing body; a tubular cavity is formed between the outer protector and the inner screwing body; the outer circumference of the inner screwing body is provided with external threads, and the mouth of the pipe body is provided with internal threads. The improved structure of the freeze pipe cover greatly reduces the possibility of contamination, achieves good sealing effects, avoids influence on pour-out of materials inside the pipe, facilitates screwing operations, obtains high strength, saves materials and is low in manufacturing costs.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a cryopreservation tube, in particular to an improved structure of a cryogenic tube cover. Background technique [0002] Cryopreservation tube is a kind of equipment used to store cells or other substances at low temperature, including tube cover and tube body. At present, there are external rotation type and internal rotation type between the tube body and tube cover, and each has its own advantages. Disadvantages, but no matter what kind of structure, the screw connection part on the tube cover and the tube body is exposed. When extracting the substance in the cryopreservation tube, the operator needs to separate the tube cover and the tube body of the cryopreservation tube. The operator not only needs to hold the tube cover and the tube body, but also needs to hold the straw to absorb the substance at the same time. Especially in the case of aseptic operation, it is more difficul...
