Abstract

The utility model relates to a tube inserting training model for a newborn's trachea, which is used for simulating newborn's asphyxia first-aid. The utility model is characterized in that the back head part of a newborn's head part model is in a coronal plane (1) and can be stably put down, and an elliptical hole is arranged below the coronal plane. A trachea (3) arranged in the hole is disconnected with a nasal passage (2) and is communicated with a bronchus (4) which is communicated with simulating lungs, and the outer sides of the trachea and the nasal passage are provided with flap valves (5) which can be lifted or put down. When a tube is inserted into from an oral cavity (or nares) and enters the trachea through a pharyngeal part, a gasbag (7) is inflated and enlarged when in pressurization, and the gasbag is retracted when the pressurization is stopped. The gas back flushes out, the clogging is eliminated, the function of gas change is generated, and the first aid succeeds and has vivid image. The utility model can be used for the tube inserting training and the teaching demonstration for a newborn's trachea in asphyxia, and can also be used for the teaching and the practice training of medicine colleges and schools.

Description

The endotracheal tube for infant training pattern

Affiliated technical field

The utility model relates to the medical teaching instrument, relates in particular to a kind of endotracheal tube for infant training pattern that is used to simulate the asphyxia neonatorum first aid.

Background technology

Asphyxia neonatorum is that the respiratory tract obstruction causes, generally adopts the attraction technology to rescue, under the technology of attraction failure scenarios, and palpus row endotracheal tube for infant, the releasing anoxic of directly ventilating is to save life.Existing trachea cannula technology is all directly carried out on one's body true man, requires action accurately skilled, and least bit mistake can not be arranged, its weak point is: emergency treatment technique is complicated, mishandling missing an opportunity because of a delay, then threat to life, and chance is few, and security is little, and then difficulty is bigger to the beginner for this.

Summary of the invention

At existing asphyxia neonatorum emergency treatment technique complexity, the problem that chance is few, it is the purpose of this utility model that a kind of endotracheal tube for infant training pattern that is used to simulate the asphyxia neonatorum first aid is provided.

The technical scheme in the invention for solving the technical problem is: mainly be made up of mouth, nose, larynx, the tracheae of neonate's head model and emulation, it is characterized in that: the occiput of neonate's head model is a coronal-plane 1, can steadily put down, below the coronal-plane that cuts, establish an ellipticity hole, the tracheae 3 that is provided with in the hole disconnects with nasal meatus 2, and tracheae communicates with bronchus 4, and bronchus 4 communicates with simulated lung, in the outside of tracheae, nasal meatus flap valve 5 is arranged, can be cocked or put down.Simulated lung is flexible air bag 7, sprains when not inflating; The neck 8 of endotracheal tube for infant training pattern links to each other with movable lasso 9, and is can be with head upright or put down; Flexible air bag 7 has 2, with simulation lung.

The beneficial effects of the utility model are: when intubate is inserted by oral cavity (or nostril), through the pharyngeal tracheae that enters, airbag aeration enlarges during pressurization, stops pressurization, the air bag retraction, and gas recoils out, by normal per minute respiration rate pressurization, lifelike image.Can be used for asphyxia neonatorum trachea cannula training and demonstration lesson.

Description of drawings

Following root knot is closed drawings and Examples and the utility model is further specified as follows:

Accompanying drawing is neonate's head model of the present utility model rear portion coronal-plane synoptic diagram.

Wherein: 1 coronal-plane, 2 nasal meatus, 3 tracheaes, 4 bronchuses, 5 flap valves, at the bottom of 6 tongues, 7 air bags, 8 necks, 9 movable lassos.

Embodiment

Referring to accompanying drawing, the endotracheal tube for infant training pattern adopts whippy polyvinyl chloride resin to make, and practising near clinical practice operation and teaching, and specially increases the weight of base; The occiput of neonate's head model is a coronal-plane 1, can steadily put down, below the coronal-plane that cuts, establish an ellipticity hole, the tracheae 3 that is provided with in the hole disconnects with nasal meatus 2, tracheae communicates with bronchus 4, bronchus 4 communicates with simulated lung, in the outside of tracheae, nasal meatus flap valve 5 is arranged, can be cocked or put down.Put down at ordinary times and cover at the bottom of tracheae 3 and the tongue 6; When flap valve 5 is cocked, can check then whether intubate correctly inserts tracheae; The movable lasso 9 of the fixed mount on the endotracheal tube for infant training pattern links to each other with neck 8, makes it can be with head upright or put down, and when the head of model keeps flat, is the layback position, and oral area opens; Flexible air bag 7 has 2, with simulation lung.Simulated lung is flexible air bag 7, and available elastomeric material is made, and sprains when not inflating;

During intubate, if action is correct, sleeve pipe is by oral cavity (or the nostril is through nasal meatus), but sucking-off amniotic fluid, blood or sputum, get rid of and stop up, intubate is again through pharyngeal arrival tracheae, and air bag 7 inflations during pressurization are not when pressurizeing, gas is discharged through bronchus, tracheae by air bag 7, produces ventilatory, the first aid success.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification that above embodiment did, equivalent variations and modification still belong in the scope of technical solutions of the utility model.

Claims

1, a kind of endotracheal tube for infant training pattern, mainly formed by mouth, nose, larynx, the tracheae of neonate's head, neck phantom and emulation, it is characterized in that: the occiput of neonate's head model is coronal-plane (1), an ellipticity hole is established in the coronal-plane below of cutting, be provided with tracheae (3) in the hole and disconnect with nasal meatus (2), the tracheae of gap, the outside of nasal meatus have flap valve (5) bronchus (4) to communicate with simulated lung.

2, endotracheal tube for infant training pattern according to claim 1 is characterized in that said simulated lung is flexible air bag (7).
