Description
Technical Field
The utility model relates to an auxiliary reproduction technology, in particular to a novel trace semen freezing set.
Background
In the auxiliary reproduction technology treatment, a plurality of male patients receiving the auxiliary reproduction treatment are weak teratospermia, the sterility caused by the factors of the male accounts for 40% -50%, the azoospermia accounts for about 10% of the male sterility problem, and 1% of the male population worldwide is affected, so that each sperm is sufficient and precious, and needs to be divided into a plurality of parts for freezing preservation, each available sperm is preserved as much as possible for the subsequent auxiliary reproduction insemination, the damage of blood-testosterone barrier and the sexual function damage caused by the repeated operation of the patients are avoided, and the psychological pressure and the economic burden of the patients can be reduced.
The prior art comprises a wheat tube freezing method: the embryo freezing straw is cut into 2.5cm long parts under aseptic condition, one end is sealed by a plastic plug, 15-20ul of sperm suspension is injected into a miniature carrier rod through a micromanipulation needle, and the other end is also sealed by the plastic plug. 5-6 micro-straws are placed into a freezing tube, and the freezing tube is fumigated on liquid nitrogen steam for 30min and then put into liquid nitrogen for preservation. The method is suitable for freezing a small amount of sperms, but is not suitable for freezing severely damaged or immature sperms, and the sperms are easy to adhere to the tube wall during freezing to cause sperm loss.
In order to solve the problems, the applicant proposes a novel micro semen freezing set.
Disclosure of Invention
The utility model aims to provide a novel trace semen freezing set, which solves the problem that sperms are easy to adhere to tube walls in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a novel freezing suit of trace semen, includes freezing straw and transfer line, freezing straw and transfer line one end are through the connecting piece intercommunication, the transfer line other end is provided with the syringe, freezing straw other end still is provided with detachable sealing plug.
Optionally, a cotton plug is also arranged in the freezing straw.
Optionally, the connecting piece is a sampling suction head.
Alternatively, the frozen straw maximum capacity is 0.25cc and the syringe maximum capacity is 1ml.
The beneficial effects are that: 1. by arranging the freezing straw and the injector, the repeated flushing of the freezing straw is completed, and the problem that sperms are easy to adhere to the tube wall in the prior art is solved.
2. Through setting up the cotton plug, the problem of exhaust when freezing the straw has been solved.
3. By arranging the sample adding suction head, the problem that the infusion tube is connected with the straw in the prior art is solved.

FIG. 1 is a schematic diagram of an embodiment of the present utility model;
FIG. 2 is a schematic view of a frozen straw structure according to an embodiment of the utility model.
In the figure: 1. freezing the wheat tube; 2. a sealing plug; 3. a tampon; 4. an infusion tube; 5. a sample adding suction head; 6. a syringe.
Detailed Description
The following description of the preferred embodiments of the present utility model refers to the accompanying drawings, which make the technical contents thereof more clear and easier to understand. This utility model may be embodied in many different forms of embodiments and should not be construed as limited to the embodiments set forth herein.
In the drawings, like structural elements are referred to by like reference numerals and components having similar structure or function are referred to by like reference numerals. The dimensions and thickness of each component shown in the drawings are arbitrarily shown, and the present utility model is not limited to the dimensions and thickness of each component. The thickness of the components is exaggerated in some places in the drawings for clarity of illustration.
Example 1
The utility model provides a novel freezing suit of trace semen, includes freezing straw 1 and transfer line 4, and freezing straw 1 and transfer line 4 one end are passed through the connecting piece and are linked together, and the transfer line 4 other end is provided with syringe 6, and freezing straw 1 other end still is provided with detachable sealing plug 2.
One end of the freezing straw 1 is communicated with the infusion tube 4 through a connecting piece, the caliber of the freezing straw 1 is smaller, and a proper connecting piece is needed to be in butt joint with the infusion tube 4. After the freezing straw 1, the infusion tube 4 and the injector 6 are communicated, the injector 6 is operated to suck, and the frozen sperm suspension in the freezing straw 1 is repeatedly sucked and pushed, so that the sperms attached to the inner wall of the freezing straw 1 are flushed down as much as possible during the operation, and the loss of the sperms is reduced as much as possible.
The utility model preferably uses the sample loading suction head 5 as a connecting piece, and the sample loading suction head 5 is used as a stock consumable in a chemistry and biology laboratory, is conical, can adapt to the installation requirements of different calibers, and is firm and practical.
The utility model preferably provides a cotton plug 3 in the frozen straw 1, which serves to isolate germs and exhaust air when the frozen straw 1 is frozen.
The utility model preferably has a maximum capacity of 0.25cc for the vial and 1ml for the syringe 6, which is used in combination, the syringe 6 and the frozen vial 1 have a small volume, which reduces errors in handling, and the mentioned frozen vial 1 and syringe 6 are of relatively easy to obtain gauge and have little impact on the overall device cost.
The sealing plug 2 is adopted in the utility model, and the sealing plug 2 is required to be plugged into the freezing straw 1 during freezing, so that the loss of sperm suspension is prevented; when the sperm suspension is sucked, the sealing plug 2 is required to be pulled out, so that the air pressure in the straw is ensured to be stable, and the flow of the sperm suspension is not blocked
Working principle: when the sperm suspension is extracted from the freezing straw 1, 1ml of the injector 6 is connected into the infusion tube 4, meanwhile, the infusion tube 4 is connected into a 200ul sample-adding suction head 5, one wide end of the sample-adding suction head 5 can be connected into one end of the freezing straw 1 with the cotton plug 3 when in freezing, the sperm suspension in the straw is repeatedly washed by pulling a piston rod of the injector 6, and then the sperm suspension of the cryopreservation liquid is quantitatively sucked into the injector 6 for use; after the sperm suspension is pushed into the freezing straw 1 from the injector 6 for preservation, the sealing plug 2 is plugged, so that sperm cryopreservation liquid can be sealed in the freezing straw 1 completely, marked and placed on a freezing bracket, fumigated on liquid nitrogen steam for 30min according to a standard freezing procedure and then put into liquid nitrogen for preservation.
While the fundamental and principal features of the utility model and advantages of the utility model have been shown and described, it will be apparent to those skilled in the art that the utility model is not limited to the details of the foregoing exemplary embodiments, but may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
