Abstract
The utility model discloses a carbon dioxide cleaner applied to a breathing mask. The carbon dioxide cleaner comprises a shell (1), wherein the shell (1) is provided with an air inlet and an air outlet (2, 3) which are communicated with a breathing loop tube and a mask respectively; and a material layer (4) capable of absorbing carbon dioxide is formed in the shell (1). The carbon dioxide cleaner has the advantages: the carbon dioxide cleaner is arranged between the mask and a breathing loop and is used for absorbing CO2 exhausted by a patient during breathing, so that the content of CO2 in the breathing loop is lowered, and the life safety of the patient is ensured; and the carbon dioxide cleaner is simple in structure, is convenient to install and use, and can be changed and replaced in time according to the color of an acid-base indicator.
Description
Technical field
This utility model relates to the medical equipment technical field, a kind of specifically carbon dioxide removal device that is used for breathing mask.
Background technology
In the clinical position, using the respirator oxygen supply is to guarantee patient respiratory, saves one of important means of patient's life.In general, the respirator oxygen supply can be divided into two kinds of patterns: tracheal intubation control breathing and face shield be autonomous/and assisted respiartion.For consciously, autonomous respiration is arranged, can't carry out the patient of tracheal intubation control breathing, how with face shield autonomous/assisted respiartion is main.Face shield is autonomous/and during assisted respiartion, the patient is often because breathing circuit/face shield with facial fixing too tight, causes CO
2Accumulate.Severe patient causes CO
2Anesthesia, what patient exhaled does not answer, even cardiac arrest.
The utility model content
The purpose of this utility model provides a kind of carbon dioxide removal device that is used for breathing mask, reduce face shield autonomous/CO takes place in the patient during assisted respiartion
2The risk of accumulating is for patient's life security provides safeguard.
This utility model is used for the carbon dioxide removal device of breathing mask, comprising: housing, offer respectively on the said housing and be used for the air inlet/outlet that is connected with breathing circuit pipe, face shield, be provided with in the said housing can absorbing carbon dioxide material layer.
Be provided with filter course between the material layer of said ability absorbing carbon dioxide and the air inlet/outlet.
The material of said ability absorbing carbon dioxide is the basic species of ability absorbing carbon dioxide.
Said housing is a transparent shell.
Also comprise acid-base indicator in the material layer of said ability absorbing carbon dioxide.
The advantage that this utility model is used for the carbon dioxide removal device of breathing mask is: this utility model is placed between face shield and the breathing circuit CO that discharges when absorbing patient respiratory
2, reduce CO in the breathing circuit
2Content, ensure patient's life security; This utility model is simple in structure, and installation, easy to use can in time be changed according to the change of acid-base indicator color.
Description of drawings
Fig. 1 is the structural representation that is used for the carbon dioxide removal device of breathing mask.
The specific embodiment
Below in conjunction with accompanying drawing; This utility model is further specified: according to shown in Figure 1; A kind of carbon dioxide removal device that is used for breathing mask; Comprise: housing 1, offer respectively on the said housing 1 and be used for the air inlet/ outlet 2,3 that is connected with breathing circuit pipe, face shield, be provided with in the said housing 1 can absorbing carbon dioxide material layer 4.
Said can absorbing carbon dioxide material layer 4 and air inlet/outlet 2, be provided with filter course 5 between 3, said filter course 5 can be spongy layer or other can prevent that material gets into the filter course that the patient respiratory road can make gas pass through again simultaneously in the material layer.
The material of said ability absorbing carbon dioxide is the alkaline powder of ability absorbing carbon dioxide, like calcium oxide, calcium hydroxide, sodium hydroxide or their mixture.
Said housing 1 is a transparent shell.
Also comprise the acid-base indicator powder in the material layer 4 of said ability absorbing carbon dioxide, like Herba Cladoniae rangiferinae or phenolphthalein.
Claims (5)
