Abstract

The utility model provides a back-flow preventing artificial insemination tube used in uterine cavity, which comprises a soft tube; on side of the soft tube is formed with a through hole; an air bag is disposed on the outer circumferential wall of the front part of the soft tube; a conduit is mounted in the soft tube; and a liquid guiding cavity is formed inside the conduit; a liquid hole is opened on one end of the liquid guiding cavity; an air guiding channel is formed on the side wall of the soft tube; the inlet end of the air guiding channel is connected with an air guiding tube; and the outlet end of the air guiding channel is connected with the air bag. The utility model can overcome the disadvantages of the prior arts, can prevent seminal fluid from back-flowing; increase the sperm concentratin in uterine cavity, thereby, improves conception rate greatly, and avoids the pains and inconvenience of patient caused by multi-time artificial inseminations. The utility model also has the advantages of using convenience, easily controlled and low cost.

Description

A kind of anti-ins's pipe that backflows

Technical field

This utility model relates to medical apparatus and instruments, is a kind of anti-ins's pipe that backflows.

Background technology

Adopting the spermatozoa insemination method to treat some infertility is this area method commonly used, yet the seminal fluid input pipe that adopts during artificial insemination is by abroad buying, its price comparison costliness, also there is the phenomenon that seminal fluid is backflowed simultaneously, seminal fluid backflows and causes sperm concentration decline in the uterine cavity, pregnancy rate descends, and needs repeatedly artificial insemination, brings inconvenience and misery to the patient.

Summary of the invention

The purpose of this utility model is, a kind of anti-ins's pipe that backflows is provided, and it can solve the deficiency that prior art exists, and prevents that seminal fluid from backflowing.

This utility model for achieving the above object, be achieved through the following technical solutions: a kind of anti-ins's pipe that backflows, comprise flexible pipe, flexible pipe one side is offered through hole, on the forward periphery wall of flexible pipe air bag is set, conduit is installed in the flexible pipe, offer liquid guiding cavity in the conduit, liquid guiding cavity one end is offered liquid outlet, offers air guide channel on the sidewall of flexible pipe, the arrival end of air guide channel is connected with airway, and the port of export of air guide channel communicates with air bag.One end of airway is installed the inflation handle, and the gas switch valve is installed on the airway.One end of flexible pipe is installed the taper connection seat, offers groove in the taper connection seat.One end of conduit is installed square handle, adopts direct insertion the connection between square handle and the conduit.

Advantage of the present utility model is: it can solve the deficiencies in the prior art, can prevent that seminal fluid from backflowing, and increases sperm concentration in the uterine cavity, and pregnancy rate is increased substantially.Avoided repeatedly carrying out artificial insemination to the patient cause painful and inconvenient.This utility model also has easy to use, is easy to control, advantage such as with low cost.

Description of drawings

Accompanying drawing 1 is this utility model structural representation.

The specific embodiment

The contrast accompanying drawing is described further this utility model.

Structure of the present utility model has a flexible pipe 2, flexible pipe 2 one sides are offered through hole 5, on the flexible pipe 2 forward periphery walls air bag 4 is set, conduit 3 is installed in the flexible pipe 2, offer liquid guiding cavity in the conduit 3, liquid guiding cavity one end is offered liquid outlet 6, offers air guide channel 7 on the sidewall of flexible pipe 2, the arrival end of air guide channel 7 is connected with airway 8, and the port of export of air guide channel 7 communicates with air bag 4; Said structure of the present utility model can be realized the purpose of this utility model, reaches result of use.In order to further facilitate operation, be easy to control the gas amount of charging into, at an end of airway 8 inflation handle 10 is installed, gas switch valve 9 is installed on the airway 8.

One end of flexible pipe 2 described in the utility model is installed taper connection seat 1, offers groove 12 in the taper connection seat 1, and this structure is convenient to place the handle of conduit 3 one ends.

One end of conduit 3 described in the utility model is installed square handle 11, adopts direct insertion the connection between square handle 11 and the conduit 3, conveniently installs and uses, and is easy to control the influx of seminal fluid.

Air bag 4 described in the utility model adopts medical grade rubber to make, and wall thickness is generally the 0.5-1.5 millimeter, before the unaerated, is attached on the periphery wall of flexible pipe 2.When this utility model uses, flexible pipe 2 is inserted in the uterine cavity, seminal fluid is by conduit 3 inputs, seminal fluid enters in the uterine cavity through liquid outlet 6 and through hole 5, at this moment, the intracavity of air bag 4 between uterine cavity collar extension and internal orifice opened gas switch valve 9, push inflation handle 10, gas is by airway 8, air guide channel 7 enters air bag 4, gets lodged in uterine cavity internal orifice place after air bag 4 inflations, closes gas switch valve 9 this moment, insemination tube described in the utility model was placed in uterine cavity 30-40 minute, seminal fluid is fully entered in the uterine cavity, the seminal fluid phenomenon of backflowing do not occur, at last gases in the air bag 4 are bled off, this utility model insemination tube is taken out, finish artificial insemination.
