Abstract
Pressure of a trachea conduit cuff influences damaging degree of the trachea, which can cause critical complications. At present, the solution is that the cuff is aerated with air volume which is exactly 'not air leaking' during aerating, no exact quantified index is provided, with complex operation. The technical proposal of the utility model is that the top end of a liquid storage bottle is connected with a tee pipe, the bottom end of the liquid storage bottle is connected with a graded tube, a three-way switch is utilized for opening and closing the tee pipe, the front end (thin end) of the tee pipe can be connected with a trachea conduit outer air bag, and the other end can be connected with an injector. The liquid storage bottle is filled with water to zero mark of the graded tube, the connecting end of the air bag of the tee pipe is connected with the trachea conduit outer air bag, an injector of 10 ml is connected with the other end of the tee pipe which is in completely open state, then the trachea cuff is injected with air, the water column inside the graded tube simultaneously ascends, and the air injection volume of the cuff can be adjusted according to the height of the water column. The utility model can precisely and simply measure air injection volume of the trachea conduit cuff and cuff pressure after aerating.
Description
Technical field
This utility model relates to the new equipment of cuff for endotracheal catheter inflation after the tracheal intubation, the aeration quantity of judgement cover capsule that can be accurate, easy and inflation back cover bag pressure power.
Background technology
The pressure of cuff for endotracheal catheter size directly influence the tracheal injury degree, even even cause mucosa necrosis, esophago-tracheal fistula, common way of past be employing when ventilating just the gas volume of " air tight " to sleeve bag gas-filling, the quantizating index that neither one is definite; Though Cardiff cover bag pressure force controller comes out, because of it costs an arm and a leg; Use still not extensive clinically.Annulus trachealis and the normal mean arterial pressure of tunica mucosa tracheae blood capillary are 32mmHg, and the cover intracapsular pressure is 22mmHg (30cmH to keep when air-breathing
2O), be 15mmHg (20cmH during expiration
2O) and do not have gas leakage for the most desirable.Prevent that at body measurements inhale required cover bag pressure power finds that the cover intraluminal pressure is 20cmH by mistake
2Mistake can take place during O inhale, and 〉=25cmH
2Mistake does not then take place during O inhales.At present only observe the feel of capsule clinically with inflation back cover capsule and determine to inflate what; Or give positive airway pressure after the inflation, air tight in the auscultation of trachea place with stethoscope is standard.These ways easily cause under-inflation or hyperinflation.
Summary of the invention
In order to overcome the deficiency of traditional method, this utility model provides a kind of cuff for endotracheal catheter level pressure inflation instrument, mensuration cuff for endotracheal catheter aeration quantity that this device can be accurately easy and inflation back cover bag pressure power.
The technical scheme that its technical problem that solves this utility model adopts is: the liquid containing bottle top links to each other with a tee T, and the liquid containing bottle bottom links to each other with a graded tube; Utilize three-way cock can control the switching of tee T; The front end of tee T (thin end) can be connected with the outer air bag of endotracheal tube, and the other end can link to each other with syringe.Graded tube place at zero point will be filled in the liquid containing bottle, the air bag link of tee T is connected the outer air bag of endotracheal tube, utilize the syringe of a 10ml to be connected to the other end of tee T, tee T is in full-gear, gas injection in tracheal tampon, as seen water column rises simultaneously in the graded tube, overlaps the gas injection rate of capsule according to the altitude mixture control of water column.
The beneficial effects of the utility model are, can be accurately, gas injection reaches certain pressure in the cover capsule easily, prevents hyperinflation or deficiency, and the pressure in the sustainable measuring unit capsule changes; Be easy to penetration and promotion.
Description of drawings
Comprise: Fig. 1 is a front elevation of the present utility model,
Fig. 2 is a side view of the present utility model,
Among the figure: 1, graded tube; 2, the syringe link; 3, tee T and switch; 4, liquid containing bottle; 5, the air bag link.
The specific embodiment
Utilize a syringe in liquid containing bottle (4), to be filled with water to the place at zero point, connect a 10ml syringe at syringe link (2) then, the outer air bag of air bag link (5) and tracheal tampon is connected, by the gas injection of 10ml syringe; Observe the height of water column in the graded tube (1), its height value is cover capsule force value, in the operating process all the time with liquid containing bottle perpendicular to ground.When needing continuous monitoring cover bag pressure power, only capsule and liquid containing bottle direction are open to get final product to overlapping with tee T after the gas injection.
Claims (1)
1. a cuff for endotracheal catheter level pressure is inflated instrument, the liquid containing bottle top is connected with a tee T, the bottom is connected with a graded tube, utilize three-way cock can control the switching of tee T, the front end of tee T can be connected with the outer air bag of endotracheal tube, the other end can link to each other with syringe, it is characterized in that: by tee T the outer air bag of syringe, liquid containing bottle and endotracheal tube is connected.
