Description

3D ostium of uterus expansion schematic model

Technical field

The utility model relates to medical educational utensil, specifically, relates to 3D ostium of uterus expansion schematic model.

Background technology

Pregnant woman is in pregnancy, and along with the increase in pregnant week and closing on of the expected date of childbirth, the length of canal of uterine cervix can shorten gradually; After pregnant woman enters stages of labor, ostium of uterus can be expanded to 10CM gradually just can meet being born of baby.In prior art, there is not the model getting information about canal of uterine cervix length and ostium of uterus expansion, be difficult to allow pregnant and lying-in women understand the situation of self progress of labor; When medical worker carries out relational learning simultaneously, can only be understood by practical operation, very inconvenient.

Utility model content

For the technical matters existed in prior art, the purpose of this utility model is: provide a kind of 3D ostium of uterus expansion schematic model that intuitively can show canal of uterine cervix length and ostium of uterus dilatation.

In order to achieve the above object, the utility model adopts following technical scheme:

3D ostium of uterus expansion schematic model, comprising: the displaying case of several model monomers and an accommodation model monomer; Model monomer comprises: spheroid and stretch and encase the elastic packaging body of spheroid; Elastic packaging body comprises the opening that picks and places spheroid.

Preferred as one, elastic packaging body is short silk stocking, draws materials conveniently, moderate dimensions.Short silk stocking are the short silk stocking of commercially available monotubular.

Preferred as one, spheroid is ball, has elasticity.

Preferred as one, the opening of elastic packaging body is strutted rear for circular by spheroid.

Preferred as one, the diameter of spheroid is more than or equal to 10 centimetres, and enough large spheroid fully can show ostium of uterus and open full state.

Preferred as one, after spheroid inserts short silk stocking, the blind end of short silk stocking stamps the knot shortening short silk stocking length, position unnecessary for short silk stocking can be put in order.

Preferred as one, the quantity of model monomer is multiple, and displaying case inside is individual layer lattice-shaped, and a grid holds a model monomer; Displaying case is that cube shaped, square grid arranges in the mode of rectangular array.Can according to the quantity of the state determination module monomer that will show and grid.

Preferred as one, displaying case also comprise one cover all grids can the door of switch, be convenient to take out and storage.

Preferred as one, displaying case is transparent display box, directly can check model monomer through displaying case.

Preferred as one, each grid is equipped with the tag board of labelling, and is gone out the state of canal of uterine cervix corresponding to model monomer or ostium of uterus expansion by labeled marker.

Principle of the present utility model is: by the position display canal of uterine cervix of spheroid in elastic packaging body and the state of ostium of uterus expansion, the distance of opening to spheroid of elastic packaging body and the length of analog womb neck tube, the aperture of the aperture that spheroid struts opening then analog womb mouth.

Generally speaking, the utility model tool has the following advantages:

1. can apply to clinic training and Health Education be carried out to pregnant and lying-in women, vivid simple, intuitive, very clear.The true effect experienced after helping pregnant and lying-in women, obstetrics medical personnel, trainee, the model of graduate student by touch solid goes to understand the progress of stages of labor.Allow pregnant and lying-in women understand more truly oneself to enter the situation of dilatation of cervix after stages of labor by the touch of 3D ostium of uterus expansion schematic model, be conducive to midwife and health propaganda and education is carried out to pregnant and lying-in women, thus promote the effective communication protected between trouble.And in the judgement of clinical special case, allow medical personnel, graduate student, trainee by the practical operation on model, also make them reach common understanding to special case simultaneously, also improve the skill of uterine neck internal orifice exploration technology, increase their confidence to clinical manipulation, thus promote effective raising of clinical technology.

2. structure is simple, easy to make, draws materials conveniently.
