According to the utility model, the position of the outer tube body entering into a uterine cavity under the B-ultrasonic wave can be seen clearly; the outer tube body is made of a medical polymer material with a developing function and can be shaped to be suitable for an uterus at any position; the inner tube body can be combined with the metal inner core to pass through an irregular uterine cavity very well, thus playing a supporting role; the disposable embryo transplanting tube has the advantages of visible operating process, accuracy in positioning, good using effect, reasonable design, simplicity, convenience and safety in operation, disposability and capability of preventing cross infection; the disposable embryo transplanting tube is applicable to an in-vitro fertilization technique, namely embryo transplantation: a fertilized egg or an embryo is transplanted into the uterine cavity through the vagina.
Description
Technical field
This utility model relates to medical apparatus and instruments, especially relates to one and can be used in vitro fertilization art--embryo transfer transvaginal by germ cell or embryo transfer to the disposable use embryo transplantation tube in cavity of uterus.
Background technology
Society, due to the quickening of work rhythm and the continuous enhancing of work competitive pressure, and under the combined influence of other various factorss, add patient's self reason, the number of infertile patient increases day by day, implements to become pregnant clinically in human assistance mode, has become effective medical procedure.At present, usual way is the embryo of external fertilization to be transplanted to the uterine cavity that enters women with apparatus, and not only simple and safety, goes back no pain.
But the embryo transplantation tube that used on the market is at present essentially external import, not only expensive, and due to the difference of external and Asians's physique structure, make the size of product extremely not meet clinical requirement.
Summary of the invention
The purpose of this utility model is to provide that a kind of operating process is visual, accurate positioning, good, reasonable in design, easy to operate and safe, the disposable use of result of use, can prevent the embryo transplantation tube of cross infection.
The purpose of this utility model is achieved in that
A kind of disposable use embryo transplantation tube, feature is: be made up of two outer tube and inner tubes that separate and be tubulose, wherein: outer tube is made up of the outer tube body and the outer tube joint that are connected as a single entity again, inner tube is again by the interior tube body being connected as a single entity, metal inside and inner pipe joint composition, outer tube joint is fixed on the top of outer tube body, inner pipe joint is fixed on the top of interior tube body, the internal diameter of metal inside is slightly larger than the external diameter of interior tube body, and metal inside is enclosed within the outer wall of interior tube body, the top of metal inside is fixed on the bottom of inner pipe joint, the external diameter of metal inside is less than the internal diameter of outer tube body, the external diameter of inner pipe joint is less than the internal diameter of outer tube joint, metal inside and interior tube body all can be inserted in outer tube body, the bottom of inner pipe joint is stuck in the top of outer tube joint.
Metal inside, interior tube body, outer tube body are elongated strip shaped, and the length of interior tube body is less than the length of outer tube body.
The outer surface of tube body is provided with two graduation marks outside, the bottom 4cm of the outer tube body of Article 1 graduation mark distance, the bottom 5cm of the outer tube body of Article 2 graduation mark distance.
Outer tube body is enclosed within outer tube boot, and interior tube body is enclosed within interior tube boot.
Outer tube joint, inner pipe joint are injection molded by medical macromolecular materials, and outer tube body, interior tube body, outer tube boot, interior tube boot form by medical macromolecular materials trombone slide, and metal inside is drawn and formed by medical stainless steel.
This utility model is made up of outer tube and inner tube, outer tube is made up of the outer tube body and the outer tube joint that are connected as a single entity again, inner tube is made up of the interior tube body, metal inside and the inner pipe joint that are connected as a single entity again, outer tube and inner tube are wrapped up with sheath respectively, before dispatching from the factory, having adopted ethylene oxide sterilizing, is disposable use.This utility model can enter the position of uterine cavity by the outer tube body of seeing under B ultrasonic clearly, outer tube body is the medical macromolecular materials that adopt band to develop, and can be moulding, be applicable to the uterus of any position, and interior tube body is combined with metal inside, can pass through well irregular uterine cavity, play a supporting role.Therefore, the utlity model has that operating process is visual, accurate positioning, good, reasonable in design, easy to operate and safe, the disposable use of result of use, can prevent from the advantage of cross infection being applicable in vitro fertilization art--embryo transfer transvaginal by germ cell or embryo transfer in cavity of uterus.

Detailed description of the invention
Below in conjunction with embodiment and contrast accompanying drawing this utility model is described in further detail.
A kind of disposable use embryo transplantation tube, formed by two outer tube 1 and inner tubes 2 that separate and be tubulose, wherein: outer tube 1 is made up of the outer tube body 11 being connected as a single entity and outer tube joint 12 again, inner tube 2 is again by the interior tube body 21 being connected as a single entity, metal inside 22 and inner pipe joint 23 form, outer tube joint 12 is fixed on the top of outer tube body 11, inner pipe joint 23 is fixed on the top of interior tube body 21, the internal diameter of metal inside 22 is slightly larger than the external diameter of interior tube body 21, and metal inside 22 is enclosed within the outer wall of interior tube body 21, the top of metal inside 22 is fixed on the bottom of inner pipe joint 23, the external diameter of metal inside 22 is less than the internal diameter of outer tube body 11, the external diameter of inner pipe joint 23 is less than the internal diameter of outer tube joint 12, metal inside 22 and interior tube body 21 all can be inserted in outer tube body 11, the bottom of inner pipe joint 23 is stuck in the top of outer tube joint 12.
