Description

Inhalation anesthesia induction mask capable of preventing tail gas leakage
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a prevent induced face guard of inhalation anesthesia that tail gas revealed.
Background
With the development of the technical level of anesthesia and the increasing variety of anesthetic drugs, the choice of anesthetic method is increasing, and particularly with the continuous improvement of the performance of inhalation anesthetic drugs, the inhalation anesthetic method is adopted more and more in clinical practice.
The inhalation anesthesia is usually used in the maintenance phase of general anesthesia and is rarely used in the anesthesia induction phase because the inhalation anesthesia has small influence on circulation, takes effect quickly, is removed quickly, is convenient to adjust the anesthesia depth and the like, and the current anesthesia inhalation induction is mainly applied to the anesthesia induction of infants. Introduced in 2017 edition expert guidance for inducing inhalation anesthesia in children, three methods for inducing inhalation anesthesia are available: concentration increasing method/tidal volume method/spirometric method. However, these three induction methods are not widely used in general anesthesia induction, and the reasons for this are: 1. inhalation induction takes effect faster than intravenous induction; 2. the pressurization of the mask during inhalation induction easily causes suffocation feeling of the patient, and the anesthesia experience is poor; 3. when inhalation induction is performed, a high concentration of inhalation anesthetic is required, and the induced mask is not airtight, so that a large amount of inhalation anesthetic is often leaked, and the physical health of medical workers is affected.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: overcomes the defects in the prior art, provides an anesthesia induction mask with an improved structure, further optimizes the inhalation anesthesia induction method, and improves the physical and mental safety of patients and medical workers.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a prevent inhalation anesthesia induction face guard that tail gas revealed, has the main part and is the housing of transparent form, is provided with the anesthetic on the housing and inserts the mouth still be provided with the tail gas discharge port that outwards stretches out on the housing, be provided with the emission switch that switches on and close the inside and outside of face guard on the tail gas discharge port, the housing outside still is provided with the negative pressure and takes over, one end is close to for the negative pressure take over tail gas sunction inlet, the other end of tail gas discharge port are the negative pressure interface that links to each other with outside negative pressure device.
In order to control the suction force of the tail gas suction inlet, one structure is that the negative pressure connecting pipe is provided with a regulating valve for regulating the suction amount.
In order to facilitate the processing and manufacturing of the mask, the negative pressure connecting pipe is fixed on the outer part of the cover shell through a bracket.
The other structure which is equivalent to controlling the suction force of the tail gas suction inlet is that the position of the negative pressure connecting pipe on the bracket can be adjusted so as to ensure that the distance between the tail gas suction inlet and the tail gas discharge outlet is variable.
The utility model has the advantages that: the utility model discloses set up exhaust port on the induced face guard of anesthesia and set up the tail gas sunction inlet that links to each other with negative pressure device near exhaust port, make the patient not have stifled sense of stifling of stuffy gas on the one hand, on the other hand makes the unnecessary induced gas of induced in-process concentrate to discharge and collect by negative pressure device and take away, has prevented that patient and medical staff's mind and body from receiving the harm.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the device comprises a housing, 2, an anesthetic inlet, 3, a tail gas discharge port, 4, a discharge switch, 5, a negative pressure connection pipe, 5-1, a tail gas suction inlet, 5-2, a negative pressure connector, 6 and a support.
Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Fig. 1 is a concrete structure of the utility model, the housing 1 that has the main part and be the transparence has, is provided with anesthetic on the housing and inserts mouthful 2, still is provided with the exhaust vent 3 that outwards stretches out on housing 1, is provided with on the exhaust vent 3 and switches on the inside and outside emission switch 4 that closes of face guard, and housing 1 outside still is provided with negative pressure and takes over 5, and 5 one end is close to the exhaust sunction inlet 5-1 of exhaust vent 3, the other end are the negative pressure interface 5-2 that links to each other with outside negative pressure device are taken over to the negative pressure.
In fact, the suction force of the negative pressure device is often required to be adjustable, some negative pressure devices have the pressure adjusting function, and the mask only needs to use the structure shown in the attached figure 1, namely, the tail gas suction inlet 5-1 is close to the tail gas discharge outlet 3, and the distance is fixed, if the pressure regulating valve of the negative pressure device is not positioned at the place convenient for the medical staff to operate, the negative pressure connecting pipe 5 is required to be provided with a regulating valve for regulating the suction volume, or the negative pressure connecting pipe 5 is fixed outside the housing 1 through the bracket 6, and the position of the negative pressure connecting pipe 5 on the bracket 6 can be adjusted to ensure that the distance between the exhaust gas suction port 5-1 and the exhaust gas discharge port 3 is variable, the structure is not shown in the drawing, but is easy to realize, for example, the regulating valve can be the same as the structure of the discharge switch 4, a sliding groove which slides on the bracket 6 is arranged on the negative pressure connecting pipe 5, and a locking screw is arranged at the sliding groove.
The utility model discloses a use is like this:
when in inhalation induction, firstly, a screwed pipe is used for connecting an anesthetic inlet 2 of a mask, the other section of the screwed pipe is connected with an anesthesia machine, the mask (a pressurizing mask air bag) is tightly buckled above the mouth and the nose of a patient, the oxygen flow of the anesthesia machine is opened, oxygen is output, nitrogen and oxygen are removed, an inhalation anesthesia volatilization tank is opened at the same time, a mask discharge switch 4 is opened at the same time, the patient is ordered to take deep breath, redundant inhalation induction gas can be discharged from a tail gas discharge port 3 in the induction process, most of the tail gas can be immediately sucked by a tail gas suction port 5-1 after being discharged due to the negative pressure suction of a tail gas suction port 5-1, thus the pollution of the leakage of the tail gas is avoided, meanwhile, the patient does not feel suffocation due to the opening of the tail gas discharge port 3, the patient gradually falls asleep along with the increase of the inhalation concentration, the discharge switch 4 is closed to assist in, and the trachea can be inserted to complete anesthesia induction.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable people skilled in the art to understand the contents of the present invention and implement the present invention, and the protection scope of the present invention can not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
