Description
Technical field
The utility model belongs to the field of medical instrument technology more particularly to a kind of experimental rat invasive ventilation device.
Background technique
Rat is a kind of critically important experimental animal being also in daily use, and needs to establish to rat in many experiments mechanical logical
Gas, since the glottis of rat is very narrow, and conduit used in the mechanical ventilation of rat is opposite relatively thick, holds in catheterization procedure
Rat trachea blocking easily occurs, and leads to anoxia asphyxia, breathing stops, or even dead.Currently, reported rat trachea intubation
Method has: direct cannulation method, direct-view lower steel wire guide cannula, tracheostomy tube, Endoscope-assisted under blindmate method, direct-view glottis
Intubation etc..The success rate of blindmate is very low in the case where no exposed glottis, could be succeeded by being repeatedly intubated, and is intubated
When there is different degrees of anoxia asphyxia, there are about 2/3 rats in intubation, and anoxia asphyxia is dead.Look at direct cannulation under glottis straight
Method success rate increases, but since rat glottis is than narrow, still some rat has different degrees of anoxia asphyxia,
And some rat is dead due to anoxic.After although anoxia asphyxia will not be caused using guide wire intubation under direct-view
Fruit, but the difficulty of direct-view glottis intubation itself is all larger.Endoscope-assisted intubation then needs expensive equipment and certain skill
Art means.Therefore, laboratory still mostly uses the method being intubated after tracheotomy.Intubation is convenient after tracheotomy, but it
A kind of traumatic operation, to body injure it is bigger, notch cut size, the degree of tissue damage, operation when it is sterile
The recovery that experimental rat physical function state and postoperative Organism of Rats can be all influenced whether degree and postoperative infection, increases
Influence of the non-empirical factor to experimental result.
Utility model content
The purpose of the utility model is to provide a kind of experimental rat invasive ventilation devices.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
A kind of experimental rat invasive ventilation device, including ventilation pipe, one side end periphery of the ventilation pipe cladding
There is pharyngeal cavity to clog air bag, ventilation pipe end side is connected with breeches joint, and the pharyngeal cavity filling air bag is equipped with inflation dress
It sets, the air charging system includes conduit and gas cell, and the gas cell is equipped with inflation check valve.
Further, what the ventilation pipe was connected with pharyngeal cavity filling air bag is open at one end for diagonal opening, opening
Inclined-plane and horizontal angle be 75 °, pharyngeal cavity filling air bag is also obliquely installed, and the tilt angle of pharyngeal cavity filling air bag and logical
Feed channel opening slope is consistent.
Further, the conduit is fixedly connected with ventilation pipe side wall.
Further, the length of the ventilation pipe is 5cm, and the internal diameter of ventilation pipe is 0.25cm, the bifurcated of breeches joint
Leg length is 1.5cm.
Further, the ventilation pipe is made with the rigid plastics that breeches joint is integrally formed.
Further, the pharyngeal cavity filling air bag is made of soft rubber.
The utility model has the advantage, that due to when ventilation pipe one end is open using diagonal, improves blindmate
Success rate, and diagonal opening periphery is coated with inclined pharyngeal cavity filling air bag, when pharyngeal cavity filling air bag inflation, can close pharynx
Chamber and its connected nasal cavity, gas leakage when preventing mechanical ventilation, whole device ventilatory effect is good, and intubation is simple, improves experiment
The working efficiency of person.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model use state with reference to figure.
1, ventilation pipe；2, pharyngeal cavity clogs air bag；3, gas cell；4, conduit；5, breeches joint；6, tracheae；7, esophagus；8,
Pharyngeal cavity；9, epiglottis；10, check valve.
Specific embodiment
As shown, a kind of experimental rat invasive ventilation device, including ventilation pipe 1,1 one side of ventilation pipe
Portion periphery is coated with pharyngeal cavity filling air bag 2, and pharyngeal cavity filling air bag 2 is made of soft rubber, and the ventilation pipe 1 is clogged with pharyngeal cavity
Air bag 2 be connected it is open at one end be open for diagonal, the inclined-plane of opening and horizontal angle are 75 °, setting raising in this way
Success rate when blindmate, pharyngeal cavity filling air bag 2 are also obliquely installed, and the tilt angle and ventilation pipe 1 of pharyngeal cavity filling air bag 2
Opening slope is consistent, and 1 end side of ventilation pipe is connected with breeches joint 5, and ventilation pipe 1 and breeches joint 2 are integrated into
The rigid plastics of type is made；It is not easy to deform in this way in intubation, can guarantee the success rate of intubation, the pharyngeal cavity clogs air bag
2 are equipped with air charging system, and the air charging system includes conduit 4 and gas cell 3, and conduit 4 is fixedly connected with 1 side wall of ventilation pipe,
The gas cell 3 is equipped with inflation check valve 10；The length of the ventilation pipe 1 is 5cm, and the internal diameter of ventilation pipe 1 is
The bifurcated leg length of 0.25cm, breeches joint 5 are 1.5cm.
It is when specifically used, the epiglottis 9 of the inclined-plane of ventilation pipe 1 against 6 opening of tracheae is blind this invasive ventilation device
It is inserted at the shared pathway pharyngeal cavity 8 of tracheae 6 and esophagus 7, so that pharyngeal cavity when exhaled air flow maximum is clogged gas according to air-flow adjustment direction
Capsule 2 is inflated, and pharyngeal cavity 8 and its connected nasal cavity can be closed, gas leakage when preventing mechanical ventilation, and whole operation is traumatic small and simple
The shortcomings that easy, ventilatory effect is good, can greatly improve experimenter's working efficiency, and overcome other intubations.
Embodiment described above is only that preferred embodiments of the present invention are described, and is not departing from this reality
Under the premise of new design spirit, various modifications that those of ordinary skill in the art make the technical solution of the utility model
And improvement, it should all fall into the protection scope that the utility model claims book determines.
