Abstract
The utility model discloses a kind of high-pressure injection respiratory tract surface anesthesia devices, including shell, and drug storage chamber is equipped in housing cavity, which is equipped with the forcing pipe that one end is communicated with its inner cavity, which is pierced by shell and communicates with pressurised airbag；Drug storage chamber top is additionally provided with the medicine spraying tube that one end is communicated with its inner cavity, which communicates through switching with hull outside, the spraying pesticide head with insecticide-spraying hole.The utility model has the advantages that pressurization carries out the surface anesthesia in air flue later and can mitigate the cardiovascular fluctuation that tracheal surface anlsthesia and tracheal catheter are extracted, reduce the incidence of patients during peri cardiocerebrovasculaevents events, reduce general anesthesia drug dose, reduce the restless incidence of Balance anesthesia, it can achieve good topical analgesic effects in difficult airway treatment process, increase the success rate of trachea cannula.
Description
One, technical field
The utility model belongs to the field of medical instrument technology, and in particular to one kind can be in anesthesia induction and awake gas
Glottis and the anesthesia of air flue inner surface are carried out in cannula, and are suitable for general anesthesia and are induced, regain consciousness trachea cannula and bronchoscope
The high-pressure injection respiratory tract surface anesthesia device of the surface anesthesias such as inspection and treatment.
Two, background technique
It is to avoid tracheal surface anlsthesia during general anesthesia induction, needs to give the general anesthesia drug of large dosage, this kind of method meeting
Inhibit Cardiac Function of Patients, blood pressure decline occurs.Later due to the strong stimulation of trachea cannula, blood pressure will appear again on significantly
It rises, the circular wave of this " roller-coaster " formula occurs, extremely jeopardize the life security of patient, especially advanced age and weak patients.
Terminate future trouble person in operation and violent cough of choking occur because intratracheally there is tracheal catheter, it is equally possible to jeopardize patient vitals.Tradition
Laryngotracheal topical anesthesia kit structure it is simple, can not ensure good topical analgesic effects, onset time and function and effect seriously lag behind clinic
Demand.The surface anesthesia device of disclosed Patent No. ZL201621248079.0 before this do not refer to using pressurizing device,
Cannot reach high quality topical analgesic effects and effective action time.
Three, summary of the invention
The purpose of the utility model is to provide one kind to be skillfully constructed, design is reasonable, can carry out after general anesthesia induction sufficiently
Surface anesthesia not only mitigates tracheal surface anlsthesia, moreover it is possible to reach long-acting topical analgesic effects, so that emergence is complete, reduce
Tube drawing stress reaction reduces the high-pressure injection respiratory tract surface anesthesia device of cardiocerebrovasculaevents events incidence.
To achieve the above object, the technical solution adopted in the utility model are as follows: the device includes shell, its main feature is that:
Drug storage chamber is equipped in housing cavity, which is equipped with the forcing pipe that one end is communicated with its inner cavity, the forcing pipe other end
Shell is pierced by communicate with pressurised airbag；Drug storage chamber top is additionally provided with the medicine spraying tube that one end is communicated with its inner cavity, and the medicine spraying tube is another
End is communicated through switching with hull outside, the spraying pesticide head with insecticide-spraying hole.
Using the above structure, in use, first to local anaesthetics is inserted in drug storage chamber, squeezing pressurised airbag is that drug storage is indoor
Air pressurizes, and after pressure reaches setting numerical value, turns on the switch, local anaesthetics is through medicine spraying tube and spraying pesticide head, finally by spraying
Hole sprays.This kind increases effect and the action time of airway surface anesthesia using the drug of high-pressure injection, and it is anti-to mitigate trachea cannula
Haemodynamics fluctuation when should be extracted with tracheal catheter.The utility model carries out in air flue after having the advantages that pressurization
Surface anesthesia can mitigate the cardiovascular fluctuation that tracheal surface anlsthesia and tracheal catheter are extracted, reduce patients during peri heart and brain
The incidence of vascular events, reduce general anesthesia drug dose, reduce the restless incidence of Balance anesthesia, difficult airway treatment process can
To reach good topical analgesic effects, increase the success rate of trachea cannula.The utility model is skillfully constructed, and design rationally, is tied
Structure concision and compact, manufacturing cost is cheap, using simplicity, has filled up the blank of such anesthesia outfit, is worth extensive and promotes and applies.
Four, Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that the structure of the utility model spraying pesticide head is intended to.
Five, specific embodiment
As shown in Figure 1, the utility model includes shell 13.It is intracavitary in shell 13 to be equipped with drug storage chamber 1.On the drug storage chamber 1
Portion is equipped with the forcing pipe 12 that one end is communicated with its inner cavity, which is pierced by shell 13 and communicates with pressurised airbag 2.Add
It is equipped with reverse valve 3 between pressure pipe 12 and pressurised airbag 2, prevents local anaesthetics from entering in pressuring gasbag 2.1 top of drug storage chamber is additionally provided with one
The medicine spraying tube 5 communicated with its inner cavity is held, 5 other end of medicine spraying tube is through 13 outside of switch 9 and shell, the spray with insecticide-spraying hole 6
First 11 communicate.It is connected between the medicine spraying tube 5 and spraying pesticide head 11 by screw buckle 8, using this kind of connection type, facilitates spray
The replacement and repair of pipe 5.In shell 13, the medicine spraying tube 5 at 9 rear portion of switch be equipped with pressure gauge 4, with measuring moulding pressure value, when
When pressure value is greater than 50cm water column, row sprays when can turn on the switch 9.The switch 9 includes the spanner 15 in 13 outside of shell, should
It is hinged that spanner 15 penetrates slide damper 14 intracavitary in shell 13 and in medicine spraying tube 5.Using this kind of structure, spanner 15 is unclamped, it is sliding
Dynamic baffle 14 falls, and blocks medicine spraying tube 5 and forms closing；Spanner 15 is fastened, slide damper 14 moves up, and gets through the formation of medicine spraying tube 5 and opens
It opens.As shown in Figure 1, insecticide-spraying hole 6 is located at the side of spraying pesticide head 11, using this kind of structure, spraying pesticide head 11 can enter glottis and main gas
Road, the anesthesia suitable for the operation of the air flues such as surgery of polyp of vocal cord.As required by Fig. 2, insecticide-spraying hole 6 is located at the front end of spraying pesticide head 11,
