Description

Tubular vaginal dilation assembly

Technical Field

The invention relates to gynecological medical equipment, in particular to a tubular vaginal dilation assembly.

Background

The prior vaginal dilator generally has the following structure: consists of an upper page, a lower page and a handle, and is mainly used for gynecological routine examination and operation. The two handles of the vaginal dilator are arranged on the same side and are connected through bolts, and the vaginal dilator has the following defects:

1. the physician can be hindered from operating during examination and surgery while also blocking the view of the operation and the physician needs to hold the handle continuously to keep the duck bill of the dilator open.

2. Meanwhile, the stress points of the vaginal dilator are relatively concentrated, the vaginal wall of a female patient is very sensitive, and the common or existing vaginal dilator can cause extremely strong stimulation to the vaginal wall to cause discomfort to the patient.

3. The existing device is inconvenient for a patient to put into the vagina by himself, the patient needs to go to and fro a plurality of times, the hospitalization times of the patient are increased, and the waste of medical resources is caused.

4. If the vagina of a patient bleeds, the vaginal dilator needs to be repeatedly inserted or taken out when the vaginal dilator is used for hemostasis treatment, and further the damage to the vagina wall of the patient is aggravated.

5. If a hemostatic device similar to a uterine cavity balloon is used, the shape of the hemostatic device is spherical after the hemostatic device is expanded, and the vaginal channel is columnar, so that the hemostatic balloon is difficult to perform compression hemostasis on the inner wall of the vagina.

6. The existing vaginal dilator can be used for dilating the vagina only by manually inserting the vaginal dilator into the vagina by an operator, is inconvenient for the operator and has great difficulty in self-operation by a patient.

Therefore, how to design a tube-type dilator with a size similar to a tampon to enable a patient to operate by himself is a technical problem to be solved urgently at present.

Compared with the prior art, the tubular vaginal dilation component adopting the technical scheme has the following beneficial effects:

firstly, the tubular vaginal dilator and the dilator with the tubular structure have the volume similar to that of a tampon before being inflated, so that a patient can place the vaginal dilator into the vagina by himself, and meanwhile, the placing process is relatively mild, excessive stimulation cannot occur, and the comfort level is higher.

The tube body is made of hard materials such as hard rubber and plastic, the bladder cavity is made of soft films, the bladder cavity expands outwards to extrude the vaginal wall when the inflatable dilator is inflated, the tube body is used for maintaining the structure, the inward deformation of the tube body when the bladder cavity expands is avoided, the inflatable dilator is finally integrally cylindrical, the stress is uniform when the vaginal wall is pressed, and the vaginal wall can be effectively protected.

In the preferred scheme, the tube body and the capsule cavity are made of transparent materials, and the middle part of the dilator can be used for observing the conditions of the cervical orifice and the vaginal wall (particularly the bleeding condition), or medical personnel can put the dilator into an endoscope and the like to observe the bleeding condition of the vaginal wall and the cervical condition.

There is not any to shelter from to the operation of apparatus, and close the control valve after propping up and can make the expander be in the tensioning state, need not to occupy other operating personnel work, and medical personnel can realize bimanualness when the operation.

A control valve at the end of the catheter is used to either close the catheter to maintain air pressure or open the control valve to allow rapid deflation of the dilator.

And the shape of the sac cavity is annular, and compared with the method that the spherical air bag directly extrudes the vaginal wall, the plurality of annular sac cavities form a cylindrical extrusion surface which can be better attached to the shape of the vagina (compared with the spherical extrusion surface) to apply pressure for compression hemostasis.

And a gap is reserved between the annular air bags arranged at intervals, and the gap can accommodate a part of vaginal wall to enter between the two annular air bags during extrusion, so that the extrusion pressure degree during compression is reduced, and the hemostasis compression process is relatively comfortable.

And fourthly, the gap between the capsule cavities can enable the dilator to have an anti-skidding effect and prevent the dilator from falling out of the vagina.

Fifth, in the preferred scheme, the medicine injection holes are formed in the tube body, the medicine injection holes are distributed in a large number, the surface of the covered vaginal wall is wide, medicine can be applied to a plurality of positions, and even if the vaginal wall is pressed, the medicine can be absorbed.

And a pressure gauge is arranged on the catheter, so that the pressure condition (pressure intensity and pressure intensity change) in the bladder cavity can be directly observed, if the pressure intensity is continuously increased, the bleeding and swelling conditions of the vaginal wall are not relieved, other treatment needs to be further carried out on the bleeding position, and if the pressure is reduced, the bleeding and swelling conditions of the vagina are relieved.

Seventh, this case has add and has held the pipe ware, utilizes the last movable rod of holding the pipe ware to control outer stay board and to expand outward and fold up, and the body of rod is used for the extension, when the expander is put into women's patient's vagina, can utilize and hold the pipe ware to fix the expander, and is easier during the operation, especially when the expander is inside the vagina, under the assistance of holding the pipe ware, the taking out and the position adjustment of expander are easier.

And eighthly, the inserter is arranged at the front end of the tube holder, is integrally conical, and has a round spherical front end, and is mainly used for assisting the dilator to enter the vagina.

The patient does not need to manually insert the dilator into the vagina, the dilator can be automatically sent into the vagina only by pressing the tube holder arranged in the movable rod, the insert plays a role in protecting the vagina, the operation of the patient is simple and convenient, the manual adjustment and positioning are not needed, the convenience is brought to the elderly and the people who have difficulty in moving, and the design of the front section can make the patient more comfortable and can not cause any uncomfortable feeling caused by the foreign body entering the vagina.

Meanwhile, in the process of putting and taking out the dilator, the tube holder is adopted for taking, so that an operator does not need to stretch hands into the vaginal opening, the psychology of a patient is easier to accept, and risks such as occupational exposure and the like possibly brought by hand operation are avoided.
