Description
【Technical field】
The present invention relates to a kind of trachea cannula with atomizing functions.
【Background technology】
Trachea cannula refers to the technology referred to as trachea cannula that a special endotracheal tube is inserted to tracheae through glottis, this
Technology can attract for airway patency, ventilation oxygen-supplying, respiratory tract and prevent that suction etc. provides optimum condition by mistake.
Nebulae inhalation refers mainly to aerosol therapy.So-called aerosol refers to be suspended in solid or liquid small in air
Body particulate.Therefore fog inhalation therapy is that medicine (solution or powder) is dispersed into small droplet with the device being atomized
Or particulate, it is suspended in gas, and enter respiratory tract and intrapulmonary, clean air flue is reached, humidifying airway is local
Treat the purpose of (spasmolysis, anti-inflammatory, eliminating the phlegm) and whole body therapeutic.
The operation principle of atomization mainly has two kinds：Ultrasonic atomizatio and compressed air atomization (utilizing the principle of venturi).And
The present invention relates to the technology for ultrasonic atomizatio.The aerosol that ultrasonic atomizatio is produced is by being operated in 1.7MHz center resonant frequencies
The ultrasonic wave that produces of piezoelectric chip vibration, the powerful acoustic pressure of ultrasonic wave makes the liquid hydrone of the drug containing inside medicine glass
Mutually collision, produces micron order aerosol.The blower fan inside atomizer is recycled, aerosol is blown out from air flue inside machine.
Clinically, the application using mechanical ventilation Atomization inhalation treatment lung relevant disease is more universal.Such as machinery
The treatment side of ventilation joint Pulmicort Respules gas-powered atomization inspiration treatment premature broncho-pulmonary dysplasia (BPD)
Method, utilizes the typical case of such a treatment technology.This technology, mainly will be medicinal atomized by atomizer, then accesses
To patient interface end, then being driven into patient body by gas.And patient's linkage interface of mechanical ventilation is main
For mask and trachea cannula two ways.Wherein imported via the atomization of trachea cannula and there is problems with clinic：Very
Many situation prescribe medicine things can not be efficiently entering lung, there is the risk of patient's asphyxia.
【The content of the invention】
Found by research, medicine (solution or powder) is dispersed into small droplet or particle suspension in gas (i.e.
Atomization), in by endotracheal intubation, due to temperature and humidity change, be intubated the reason such as longer and narrower and can condense,
Again solution shape or solid granular material are reverted to, is adsorbed on tube wall, causes medicine to cannot be introduced into lung, seriously
In the case of, tracheae can be caused to block, cause patient to suffocate.
In order to overcome the deficiencies in the prior art, the invention provides a kind of trachea cannula with atomizing functions, so that medicine
It is more effective to enter lung, the risk of reduction patient's asphyxia.
A kind of trachea cannula with atomizing functions, including：Gas passage, drug channel and ultrasonic wave generator, institute
State gas passage to be separated with the drug channel, the entrance of the drug channel is used to connect drug source, the medicine
The outlet of passage is arranged on the exit of the gas passage and connected with the gas passage, and the ultrasonic wave produces dress
Put and be atomized for the medicine to the outlet discharge from the drug channel.
In one embodiment,
Also include ultrasonic atomizatio chamber, the outlet of the drug channel be arranged on by the ultrasonic atomizatio chamber and with the ultrasound
Atomization chamber is connected, and the ultrasonic atomizatio chamber is arranged on the exit of the gas passage and connected with the gas passage,
The ultrasonic wave generator is used to carry out mist to the medicine for dischargeing ultrasonic atomizatio intracavitary from the outlet of the drug channel
Change.
In one embodiment,
The entrance of the drug channel is arranged on by the entrance of the gas passage.
In one embodiment,
Also include setting the drug channel and gas passage on cannula body, the cannula body.
In one embodiment,
Also include the power supply interface and supply lines of ultrasonic wave generator, the power supply interface is arranged on the gas passage
Entrance by, the supply lines connects the ultrasonic wave generator and the power supply interface, and the supply lines is fixed on
On the cannula body.
In one embodiment,
Also include gas-tpe fitting, the gas-tpe fitting is fixed on the entrance of the gas passage.
In one embodiment,
The drug channel is used to convey liquid medicine.
The beneficial effects of the invention are as follows：
Present invention offer is a kind of to realize medicinal atomized trachea cannula in patient body, particularly use lung in premature
In surface reactive material tracheal catheter during injection medication, pulmonary surfactant can be made to be more evenly distributed into each alveolar,
Avoid medication caused by being directly injected into current tracheal catheter uneven, influence medication effect.
In addition, medicine is entered by the fluid passage of trachea cannula in fluid form is closer to gas path exit port end
Position, then be atomized, it is to avoid occur the phenomenon condensed during through piping, allow medicament to more uniformly
It is distributed in alveolar, and is smoothly absorbed by patient.Avoid simultaneously in mechanical ventilation, due to suffocating caused by line clogging
Etc. the appearance of malpractice.
Application of the present invention in terms of mechanical ventilation and common intubation indistinction, can be universally used in institute's trachea cannula skill in need
The mechanical ventilation application of art.

Fig. 1 is a kind of schematic diagram of the trachea cannula with atomizing functions；
Fig. 2 is a kind of schematic diagram of the trachea cannula with atomizing functions；
Fig. 3 is schematic diagram when a kind of trachea cannula with atomizing functions inserts the tracheae of people.
【Embodiment】
The preferred embodiment to invention is described in further detail below.
As illustrated in fig. 1 and 2, a kind of trachea cannula with atomizing functions, including：Gas passage 1a, drug channel 1b
With ultrasonic wave generator 2, the gas passage 1a and drug channel 1b is separated, the drug channel 1b
Entrance be used for connect drug source, the outlet of the drug channel 1b is arranged on the exit of the gas passage 1a simultaneously
Connected with the gas passage 1a, the ultrasonic wave generator 2 is used for being arranged from the outlet of the drug channel 1b
The medicine gone out is atomized.
This trachea cannula with atomizing functions is inserted into patient's trachea, the medicine of drug source (such as syringe pump) via
The drug channel 1b outlet for being transported to drug channel 1b, then medicine be atomized by ultrasonic wave generator 2, gas
Body passage 1a entrance connection source of the gas (such as mechanical ventilation apparatus gas delivery port), gas is from entrance via gas passage
1a is discharged from gas passage 1a outlet, because the medicine after atomization enters gas passage 1a, is passed through under the drive of gas
Cross a bit of gas passage 1a and enter the tracheae of human body from gas passage 1a outlet, compared to the medicine after atomization
The prior art entered from gas passage 1a porch, greatly reduces atomization medicine regelation or is attached to gas
