Description
Technical field
The utility model relates to the field of medical instrument technology, in particular to a kind of flushable trachea cannula.
Background technique
Artificial airway patient is since the ciliary movement of swallowing reflex, cough reflex and lower respiratory tract weakens or disappears, oropharynx
Secretions and field planting bacterium easily accumulate in above catheter body air bag, form " mucus lake " in this region, become the storage of bacterium
Library becomes the important sources of VAP.Therefore effectively to prevent VAP, then tracheal catheter ontology gas must timely and effectively be removed
Retentate above capsule.
Summary of the invention
Purpose of the utility model is to solve the deficiency in background technique, it one kind is provided can effectively remove tracheae and lead
The device of the oropharynx secretions and field planting bacterium that adsorb on tube body, the device can effectively prevent the generation of VAP.
A kind of flushable trachea cannula, is made of catheter body, air bag, air injection pipe, suction tube and water injection pipe, and air bag is sky
Contact and be arranged in catheter body lower end on core structure, air bag hollow structure inner wall and catheter body outer wall, air injection pipe outer end with
The connection of air bag pressure gauge, the other end are arranged in catheter body and connect with air bag, and catheter body air bag upper end is provided with first
Through-hole and the second through-hole, first through hole are arranged in the second through-hole lower end, and suction tube outer end can be connect with negative pressure suction device, another
End is arranged in catheter body and is connected to first through hole, and water injection pipe outer end can be connect with water filling syringe, and other end setting exists
It is connected in catheter body and with the second through-hole.
The air bag is taper air bag.
The first end cap is provided on the suction tube.
The second end cap is provided on the water injection pipe.
The working principle and use process of the utility model:
In use, catheter body direct oral cavity is inserted into intratracheally, according to the constitution of different people, different models is selected to be inserted into
Different depth fills air bag through air injection pipe by air bag pressure gauge when suitable position in catheter body insertion patient airway
Gas simultaneously maintains normal pressure (25cmH2O~30cmH2O), and taper air bag can make the sealing effect of air bag and air flue more preferable, beat
The second end cap is opened, connection water filling syringe fills the water, water can be flowed out by water injection pipe from the second through-hole, by tracheae into water injection pipe
The oropharynx secretions and field planting bacterium adsorbed in catheter body are flushed at air bag upper end, and negative pressure suction device will by suction tube
It sweeps away the water containing secretion and field planting bacterium come to siphon away by first through hole, finally flow in vacuum drainage case, on suction tube
The first end cap and water injection pipe on the second end cap suction tube and water injection pipe can be protected when not in use, make inside it
Sanitation and hygiene.
The utility model has the beneficial effects that
The utility model structure is simple, easy to use, makes the secretion accumulated on glottis downcomer ontology and field planting bacterium
It washes away with water, is sucked out through suction tube, directly reduce oral nasopharynx secretions to the lower leakage of lower respiratory tract and field planting bacterium and migrate, have
Help reduce the risk and hair rate of VAP.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Specific embodiment
Refering to Figure 1, a kind of flushable trachea cannula, by catheter body 1, air bag 2, air injection pipe 3,4 and of suction tube
Water injection pipe 5 forms, and air bag 2 is hollow structure, contacts and is arranged on 2 hollow structure inner wall of air bag and 1 outer wall of catheter body and is leading
1 lower end of tube body, 3 outer end of air injection pipe are connect with air bag pressure gauge, and the other end is arranged in catheter body 1 and connect with air bag 2,
1 air bag of catheter body, 2 upper end is provided with first through hole 10 and the second through-hole 11, and first through hole 10 is arranged under the second through-hole 11
End, 4 outer end of suction tube can be connect with negative pressure suction device, and the other end is arranged in catheter body 1 and is connected to first through hole 10,
5 outer end of water injection pipe can be connect with water filling syringe, and the other end is arranged in catheter body 1 and is connected to the second through-hole 11.
The air bag 2 is taper air bag.
The first end cap 40 is provided on the suction tube 4.
The second end cap 50 is provided on the water injection pipe 5.
The working principle and use process of the present embodiment:
Refering to Figure 1, in use, 1 direct oral cavity of catheter body is inserted into intratracheally, according to the constitution of different people, choosing
It selects different models and is inserted into different depth, when catheter body 1 is inserted into suitable position in patient airway, pass through air bag pressure gauge
Air bag 2 is inflated through air injection pipe 3 and maintains normal pressure (25cmH2O~30cmH2O), taper air bag 2 can make air bag and gas
The sealing effect in road is more preferable, opens the second end cap 50, and connection water filling syringe fills the water, water can pass through water injection pipe 5 into water injection pipe
It is flowed out from the second through-hole 11, the oropharynx secretions adsorbed on tracheal catheter ontology 1 and field planting bacterium is flushed to 2 upper end of air bag
Place, negative pressure suction device by suction tube 4 by sweep away come containing secretion and be colonized bacterium water pass through first through hole 10 siphon away,
It finally flow in vacuum drainage case, the first end cap 40 on suction tube 4 and the second end cap 50 on water injection pipe 5 can not use
When suction tube and water injection pipe are protected, keep its cleaning inside hygienic.
