The present invention will be described in further detail with reference to specific examples. The following examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.
As shown in figure 1, the invention is formed by nesting an inner cover 1 and an outer cover 2 from top to bottom, wherein the inner cover 1 is arranged at the inner part, the outer cover 2 is arranged at the outer part, the nesting part is airtight and airtight, and the nesting mode is that the inner cover can slide up and down. The inner cover 1 is a cube structure with a deficient lower surface. The outer cover 2 is of a square structure with two deficient upper and lower surfaces. When a patient lies on the horizontal position, the inner mask is covered on the head and the neck of the patient, the nested structure can ensure that the distance between the upper surface of the inner mask 1 and the mouth and the nose of the patient is adjustable, and can also be used for adjusting the size of the inner space of the inner mask 1.
As shown in fig. 2, a staggered-layer windowing structure consisting of an upper layer baffle and a lower layer baffle is arranged on the inner cover 1. The lower baffle 4 is connected with the front, rear, left and right surfaces of the inner cover into an integral structure. The lower baffle 4 is provided with a clamping groove 5 on the left side and the right side. The lower baffle 4 is nested and connected with the upper baffle 3 at the left side and the right side through the clamping grooves 5, and the connection part is arranged to be slidable. The lower baffle 4 is connected with the upper baffle 3 at the front edge through a pair of elastic ropes 6. The lower baffle 4 is in a free state at the rear. The lower baffle 4 is provided with an open-nose window 12 in the middle area; the back of the upper baffle 3 is connected with a handle 7. When the handle 7 is pushed forwards and backwards, the upper baffle 3 and the lower baffle 3 are staggered, the elastic rope 7 is pulled, and the operable range of the open-nose window 12 is exposed. When the handle 7 is loosened after the operation is finished, the upper layer baffle 3 automatically returns to close the nasal cavity 12 due to the restoring force of the elastic rope 7. As shown in fig. 1, one of the left and right surfaces of the inner cover is provided with a pair of screwed pipe windows 8. The screwed pipe windowing 8 is used for ensuring normal oxygen supply and gas exchange in the inner cover 1 through an air inlet pipeline and an air outlet pipeline of the screwed pipe.
As shown in fig. 3, a neck fenestration 10 is left behind the outer cover close to the middle of the bottom, an inflatable air bag 11 is connected around the neck fenestration and used for being erected above the neck of a patient, and the inflatable air bag 11 is used for improving the tightness of the neck junction.
As shown in fig. 4 and 5, the left and right sides of the outer cover 2 are respectively provided with a glove opening window 9, the glove opening window 9 is provided with a screw tube 13, and the screw tube 13 is connected with a glove structure 14 through a screw cap 15. The glove structure 14 is formed by connecting a glove 16 with a screw cap 15 at the cuff, and the connection mode is an integral structure. The glove 16 is made of an airtight rubber material. When the screw cap 15 is tightly coupled to the screw tube 13, an operator can operate the inside of the inner shield 1 by wearing the glove 16, and the operation is completely isolated from a patient.
The inner cover and the outer cover are made of transparent plates on all sides, so that a visual operation space is ensured in the invention.
Before the oxygen storage mask is used for isolation, the oxygen storage mask is connected with one end of the threaded pipe, and the other two ends of the threaded pipe penetrate through the threaded pipe to be windowed and connected to an anesthesia machine or a breathing machine. The rest are assembled as shown in figures 1 and 2:
the application process of the invention is illustrated as follows:
when the device is used for isolating and protecting a patient to be subjected to general anesthesia tracheal intubation, when the suspected positive patient lies on an operating table, an anaesthetist covers the device on the head and neck of the patient after the three-stage protection is finished, the neck is windowed and completely erected on the neck, and the air bag is inflated by the syringe, so that the sealing effect is just achieved, and the trachea is not squeezed. After examining the anesthesia machine, the anesthesia doctor performs anesthesia intubation after preparing the anesthesia medicine and intubation tool. The method comprises the following steps:
(1) a pre-oxygen supply stage; the two hands of the anaesthetist can extend into the gloves to open the window so as to wear the gloves in the device, and the two hands of the anaesthetist are not in direct contact with the patient at the moment, so that the gas in the device can not overflow. The anaesthetist can slightly buckle the mask on the mouth and the nose of the patient under direct vision so as to ensure that the patient can inhale oxygen and exchange gas. With the increase of anesthesia, when the patient reaches the anesthesia state and the respiratory consciousness disappears, the process of supporting the lower jaw to supply oxygen is completed;
(2) and (3) anesthesia induction process: when the anesthesia is gradually deepened, an anesthesiologist can observe that a transient excitation period appears in part of patients in real time, which is manifested by agitation and cough, and the anesthesiologist does not worry about upward spray of droplets because the upper baffle is in a natural separation state. As anesthesia further progresses and the patient's breathing and consciousness disappears, the anesthesiologist can hold the patient's jaw up and fasten the mask to complete controlled breathing until the patient experiences muscle relaxation.
(3) Laryngoscope exposure and endotracheal intubation; when the patient has the mandibular joint muscle loose, the anaesthetist removes the inner glove of the device and pulls the glove outwards and everts it, which does not affect the relative sliding of the inner cover within the outer cover. Then, the left hand holds the laryngoscope, the right hand holds the handle to push the upper layer baffle open until the mouth and the nose are exposed and the window is opened, the inner box is pressed downwards and lightly until the mouth and the nose of the patient are contacted, at the moment, an anesthesiologist can complete the exposure of the laryngoscope and the trachea cannula operation, in case that the patient is presbyed to have shallow anesthesia and is expected to choke, the laryngoscope can be pulled out immediately, and due to the restoring force action of the elastic rope, the upper layer baffle can rapidly shield the mouth and the nose from opening the window to prevent the spray of the foam and the aerosol. The anesthesia can be deepened continuously, and secondary intubation can be tried after oxygen supply is performed slightly.
(4) Fixing and connecting the conduit; because the mouth-nose window is large enough, the adhesive tape fixing work of the tracheal catheter can be completed in the mouth-nose window, and the operation of connecting the tracheal catheter and the patient end of the screwed pipe can be completed. The exit nose window opening is finished after retreating, and the upper layer baffle can automatically close the exit nose window opening under the action of restoring force of the elastic rope to restore to a natural isolation state. At the moment, the head and neck of the patient, the tracheal catheter and part of the threaded pipe are all isolated in the device, so that the pollution capacity of the suspicious infection source to the surrounding environment is reduced to the maximum extent, and a double-insurance effect is achieved for surrounding medical workers.
The device is not only suitable for anesthesia intubation, but also can be applied to the protection and isolation of ICU patients with severe disease and low immunity in the aspect of a respiratory system, can prevent cross infection among patients, is more favorable for protecting the ward environment, and is convenient for deep disinfection and purification. Except that the glove structure is disposable material, other parts can be repeatedly used after being disinfected, and can be used for a long time by regularly and simply maintaining when necessary, so that the use cost is low, and medical materials are saved.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention in any way, and any person skilled in the art can make any simple modification, equivalent replacement, and improvement on the above embodiment without departing from the technical spirit of the present invention, and still fall within the protection scope of the technical solution of the present invention.
