A single handheld medical device for performing endometrial curettage and / or HSG procedures is disclosed. [Solution] The device includes a body comprising a handle integrally connected to an arm having an articulated member at its distal end. The handle comprises means for storing and pumping fluid into the uterus and locating the articulated member within the uterus using ultrasound or X-rays. The arm further comprises a shielding device operable to slidably engage with the arm of the device, and the shield and arm are configured to cover and seal the external os of the cervix to prevent backflow during use. Optional display means are disclosed, which comprises an image screen that is mountably attached to the device and communicates with a scope positioned within the arm.

The invention discloses a gynecological nursing cervix uteri medicine applying device, belongs to the technical field of cervix uteri medicine applying, and aims to solve the problems that liquid medicine is discharged in a fixed-point spraying mode, can only act on a local area of a cervix uteri external opening in a concentrated mode, is difficult to uniformly cover the inner wall of a cervix uteri canal and is prone to being too high in local liquid medicine concentration. A connecting rod is rotatably connected to one end of the guide pipe, a threaded cylinder is fixedly mounted on the surface of the connecting rod, a one-way liquid storage cylinder is fixedly mounted at one end of the connecting rod, the one-way liquid storage cylinder is slidably connected with the interior of one end of the extending pipe, and a plurality of liquid spraying pieces are arranged on the surface of the one-way liquid storage cylinder. The one-way liquid storage barrel and the liquid spraying piece are driven to rotate synchronously and are matched with the piston rod to extrude out liquid, so that the liquid medicine completely covers the inner wall of the cervical canal and the whole circumference of the cervix uteri in a centrifugal mode, and the problems that traditional medicine feeding is uneven and the local liquid medicine concentration is too high are solved.

A medical device operable to prevent reflux in the cervix is disclosed. The device includes a shield operable to cover the external os and an arm operable to penetrate the endocervical canal with a bore extending therethrough, wherein the arm includes a sleeve containing a fluid that is operable to conform to the contours of the inner lining of the endocervical canal, thus creating a strong, more efficient fluid-tight seal between the device and the surrounding tissue.

A single, handheld medical device for performing an endometrial abrasion and / or HSG procedure is disclosed. The preferred embodiment comprises a body that includes a handle integrally connected to an arm with an articulating member at its distal end. The handle comprises a means for storing and pumping a fluid into the uterus so that ultrasound or x-ray can be used to determine the location of the articulating member within the uterus. The arm further comprises a shielding device that is operable to slidably engage the arm of the device and the shield and the arm are configured to cover and sealingly engage the external os of the cervix to prevent reflux during use. Optional viewing means are disclosed, including an imaging screen mountably attached to the device and in communication with a scope disposed within the arm.

The invention belongs to the field of medical instruments, and provides a delivery analgesia midwifery device which comprises a positioning support, a guide branch pipe is fixedly installed in the middle of one end of the positioning support, a fixing hole is formed in the middle of one end of the guide branch pipe in a penetrating mode and penetrates through the positioning support, an adjusting branch pipe is movably installed in the fixing hole, and a cervical dilator is arranged in the adjusting branch pipe. The cervical dilator comprises a connecting catheter which movably penetrates through an adjusting branch pipe, a connecting probe is arranged on the edge of one end of the adjusting branch pipe, a plurality of balloons are arranged on one side, close to the connecting probe, of the outer surface of the adjusting branch pipe, and a wide-mouth groove is formed in the edge of one end of the adjusting branch pipe. Through the cooperation of the adjusting pull rope, the clamping piece and the extension spring in the guide mechanism, the position of the end head connected with the probe can be flexibly and accurately adjusted, so that the balloon of the cervical dilator can be more accurately aligned with the external opening of the cervix, the operation accuracy is greatly improved, the complexity of traditional step-by-step operation is avoided, and the operation efficiency is effectively improved.
