Description

Closed freezing pole that carries

Technical Field

The invention relates to the technical field of freezing carrying rods, in particular to a closed type freezing carrying rod.

Background

Embryo freezing is one of important technical means for preserving embryos for patients by human assisted reproductive technology, and can effectively improve the cumulative pregnancy rate of each egg taking period. The vitrification freezing technology can effectively reduce the cell freezing damage and improve the survival rate and the success rate of pregnancy of the embryos or ova after the freezing recovery. Is a method for quickly freezing embryos or ova, which is commonly used in the technical field of assisted reproduction at present. However, in the laboratories of different reproductive medicine centers, the freezing recovery effect of embryos is different, and the freezing recovery effect may be related to the freezing carrying rods used in different laboratories. At present, most of the reproductive centers in China mainly use three types of vitrification freezing carrying rods, namely an open carrying rod, a semi-closed type and a closed type commercialization carrying rod. The semi-closed type is to firstly invade liquid nitrogen and then to close, and the open type carrying rod and the semi-closed type carrying rod enable the embryo to be in direct contact with the liquid nitrogen when the embryo is frozen and stored, so that potential safety hazards of the embryo can exist. For human reproductive centers, the safety of embryos is very important, cross contamination between embryos can exist, or embryo contamination caused by microbial contamination due to the existence of liquid nitrogen, so that the use of a closed freezing carrier is particularly necessary. However, the existing closed carriers have various structures and are complex to operate.

Disclosure of Invention

The invention mainly provides a closed type freezing carrying rod, and solves the problems of various structures and complex operation of closed type carriers in the prior art.

In order to solve the technical problems, the invention adopts the following technical scheme:

the utility model provides a closed freezing pole that carries, includes inner tube, outer tube and tube cap, the one end of inner tube is provided with the gasbag, and the other end sets up to inside toper binding off, toper binding off outside cover is equipped with soft sealing ring, outer tube sliding connection is outside the inner tube of toper binding off one side, is used for promoting soft sealing ring is to the internal contraction, the tube cap sets up in the outer tube outer end. When in use, the air bag is matched with the conical closing-in to absorb or lead out sperms and ova; after the absorption, the outer tube is moved, a part of the soft sealing ring arranged at the conical closing opening is pushed forwards by utilizing the appearance, and is inwards extruded and contracted by matching with the appearance, and a tube cover is covered to realize the sealing of the conical closing opening; otherwise, the soft sealing ring is opened and reset. The whole structure is simple, the use is convenient, and the cost is low.

Furthermore, the soft sealing ring is made of silica gel. The silica gel is frozen into a solid state, and the silica gel recovers after the temperature rises, so that the cost is low and the using effect is good.

Further, a freezing groove is arranged on the inner wall of the inner pipe. The freezing tank is arranged to limit the entering sperms or ova, so that the observation and the placement are convenient.

Furthermore, a first support is arranged on the outer side of the outer pipe and in the same radial direction with the freezing groove, and a second support is arranged on a connecting seat of the air bag and the inner pipe. The arrangement of the first support and the second support can facilitate placement.

Further, the thickness of the pipe wall of the inner pipe at the freezing groove is 0.15mm-0.2 mm. This arrangement provides high refrigeration efficiency.

Further, a waterproof coating is coated on the soft sealing ring. Thus, cross contamination due to improper operation can be further prevented.

Has the advantages that: when in use, the air bag is matched with the conical closing-in to absorb or lead out sperms and ova; after the absorption, the outer tube is moved, a part of the soft sealing ring arranged at the tapered closing opening is pushed forwards by utilizing the appearance, and the soft sealing ring is inwards extruded and contracted by matching with the appearance, so that the tapered closing opening is sealed; otherwise, the soft sealing ring is opened and reset. The whole structure is simple, the use is convenient, and the cost is low.

Detailed Description

The technical solution of the enclosed freezing bar according to the present invention will be further described in detail with reference to the following examples.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and 2, the rod is carried in closed refrigeration of this embodiment, including inner tube 1, outer tube 2 and tube cap 3, the one end of inner tube 1 is provided with gasbag 4, and the other end sets up to inside toper binding off 5, the cover is equipped with soft sealing ring 6 outside the toper binding off 5, outer tube 2 sliding connection is outside the inner tube 1 of toper binding off 5 one side for promote soft sealing ring 6 is inwards shrunk, tube cap 3 sets up in outer tube 2 outer end. The soft sealing ring 6 is made of silica gel. The inner wall of the inner pipe 1 is provided with a freezing groove 7.
