Abstract
A structure for detecting the inserted tube by the inserted tube model features that the light emitting and receiving unit is used to detect the position where the tube is inserted. The device mainly comprises an intubation tube detection structure, a photoelectric sensor and a signal processing circuit. The inner cavity of the intubation detection structure is in a hyperbolic curve simulation type, and the linear inner cavity is easy to enable an intubation to pass through smoothly; the middle convex part is made into a slender hole at the symmetrical positions of two sides on the central axis, the photoelectric sensor is arranged at the position, the slender hole plays a role in filtering light, only light beams along the direction of the axis of the hole can pass through, and the rest light beams are filtered, so that the error identification of the transmitting tube and the receiving tube caused by light scattering can be avoided.
Description
Technical field
The present invention relates to a kind of medical teaching utensil.
Background technology
Existing teaching much has the intubate function with having in the medical science model, such as: trachea cannula model, nose stomach tube intubate model, catheterization model or the like.The student need reach the purpose of treatment, nursing in use with corresponding pipe such as trachea cannula, stomach tube, catheter in certain path is inserted into concrete internal organs.Although these models can both accomplish that profile is true to nature, inner structure also meets normal human's anatomical structure, and the student can't know the position that intubate arrives using this class model to do in the exercise process of intubate class, blindly operation.The result of use of model reduces greatly.If it is can there be a kind of device prompting student to be inserted into certain crucial anatomical position, very big to teaching significance.
Summary of the invention
In order to address the above problem, the invention provides a kind of intubate detection architecture, it mainly is to utilize light emission and receiving trap to measure the position that pipe inserts.
The technical scheme that the present invention taked is: it mainly is made up of intubate detection architecture, photoelectric sensor, signal processing circuit.
Described intubate detection architecture, the inner chamber of this structure are imitative hyperbolic-types; The place of middle protrusion, elongated orifices is made in the place of both sides symmetry on the axis, is installed in this position to photoelectric sensor.
Described photoelectric sensor light splitter power valve and light receiving tube, two pipes are placed on respectively in the elongated orifices of intubate detection architecture.
Described signal processing circuit comprises signal pre-processing circuit and processor, and described processor is a single-chip microcomputer.
Described light receiving tube converts light to electric current, through resistance current conversion is become voltage, converts the logic level input processor to by gate circuit again.
Described signal processing circuit also comprises display device.
The invention has the beneficial effects as follows, when carrying out the intubate generic operation, can detect the position that intubate gets into.This helps to help training of students, improves operant level.
Description of drawings
Fig. 1 is an intubate detection architecture synoptic diagram, Fig. 2 be the intubate detection architecture with Fig. 1 diagrammatic sketch half-twist synoptic diagram on transverse axis, Fig. 3 is an intubate detection architecture schematic top plan view.Wherein: 1 elongated orifices, 2 elongated orifices, 3 intubate detection architecture, 4 inner chambers.
Embodiment
Further specify below in conjunction with accompanying drawing.
Shown in accompanying drawing, this structure is made up of intubate detection architecture, photoelectric sensor, signal processing circuit.The inner chamber 4 of intubate detection architecture 3 is imitative hyperbolic-types, and this line style inner chamber makes intubate pass through smoothly easily; The place of middle protrusion; Elongated orifices 1,2 is made in the place of both sides symmetry on the axis, is installed in this position to photoelectric sensor; Elongated orifices plays the light filtration; The light beam of the direction of axis line along the hole is passed through, and remainder light beam filters, and can avoid causing because of scattering of light the wrong identification of power valve and receiving tube like this.Photoelectric sensor light splitter power valve and light receiving tube, two pipes are placed on respectively in the elongated orifices 1,2 of intubate detection architecture.Signal processing circuit comprises signal pre-processing circuit and processor, and processor is a single-chip microcomputer.The light receiving tube converts light to electric current, through resistance current conversion is become voltage, converts the logic level input processor to by gate circuit again.Signal processing circuit also comprises display device.
Again with nose stomach tube intubate model, do further describing again below.
Nose stomach tube intubate model is that model is used in a operation that is used to practise to insert stomach tube to patient, and complete head, pars oralis pharyngis, oesophagus, a stomach arranged.Can be in three stenosis of oesophagus this intubate detection architecture in succession.When not operating, the light receiving tube receives the light that the light emission pipe sends, and converts light to electric current, through resistance current conversion is become voltage, converts the logic level input processor to by gate circuit again, and display device has demonstration.When using opaque stomach tube trans-oral in stomach, to insert stomach tube, when stomach tube is narrow when being intubate detection architecture position through first, stomach tube has blocked the light beam that the light emission pipe sends; The light receiving tube does not receive light, can not convert light to electric current, the no signal input processor, and display device does not show.
Vice versa through circuit control when not having stomach tube to pass through, and display device does not show, as stomach tube through the time display device show.
The above; Only being preferred embodiment of the present invention, is not that the present invention is done any pro forma restriction, and all foundations technical spirit of the present invention is to any simple modification that above embodiment did; Equivalent variations and modification still belong in the scope of technical scheme of the present invention.
