Abstract
The utility model relates to a tracheal catheter fitting, which is characterized in that the tracheal catheter fitting is a tubular shape fitting connected on the tracheal catheter, and a reversal funnel netted filtering layer is arranged at the center part of the upper section of the fitting tube cavity; the opening on the upper end of the fitting is connected with a humidifying liquid drainage-tube inclining upward; a leading tube is connected with the groove-shaped ring ditch on the inner wall, and the lower end of the groove-shaped ring ditch is the attachment point of the reversal funnel netted filtering layer on the tube wall; and a hole with a one way valve plate is established at the center part of the netted filtering layer.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, is specifically related to a kind of structural member of endotracheal tube.
Background technology
Clinically, when rescuing critical illness patient life,, often need to carry out tracheostomy tube for removing the use that patient's upper respiratory tract blocks or be convenient to respirator.When using respirator, because totally-enclosed loop of respirator and common composition such as respirator pipeline, lower respiratory tract, guaranteed the psychological need of body preferably, need not further to optimize.And when not using respirator, the endotracheal tube mouth directly communicates with the external world, easily causes airborne dust, microbe granular etc. and enters the patient respiratory road.Also have, behind the tracheostomy tube, nasal cavity, bottleneck throat etc. lose effects such as humidifying that enters respiratory tract gas and hygral equilibriums, cause drying, cold/red-hot air easily directly enters lungs through trachea, very easily cause air flue mucosa that trachea etc. locates because of too dry degeneration, necrosis take place, come off, hemorrhage etc.; Moreover the patient in a period of time, often needs the low discharge oxygen supply behind the respirator of stopping using, but because of the endotracheal tube mouth does not have fixture, in practical operation, is difficult to guarantee that oxygen hose places in the endotracheal tube always.
For this reason, we intend by this endotracheal tube adnexa of invention, and the problems of bringing because of tracheostomy tube more than solving are with not enough.
Summary of the invention
The purpose of this utility model is the deficiency at the prior art existence, a kind of endotracheal tube adnexa is proposed, in conjunction with clinical medicine present situation and needs, dust from blocks air, microbe granular etc. enter the patient respiratory road, humidifying enters the air in the air flue, makes things convenient for many-sided improvement because of problems behind the band behind the tracheostomy tube and deficiency such as oxygen hose low discharge oxygen supply.
The technical solution of the utility model is as follows:
The endotracheal tube adnexa that the utility model proposes is the tube-like piece that is connected on the gas conduit, and central authorities are provided with the netted filtering of falling a funnel-form layer at adnexa tube chamber epimere; Adnexa upper pipes wall opening connects the humidifying liquid guiding tube of an oblique top; Humidifying liquid guiding tube links to each other with the flute profile annular groove of adnexa inwall, and flute profile annular groove lower edge is the attachment point of the netted filtering of falling infundibulate layer on tube wall; Open the aperture of a band check valve sheet in the central authorities of netted filtering layer.
In addition, in adnexa body bottom one oxygen access tube is set, the conduit fitting lower end is provided with a connecting ring.
This utility model can pass in and out gas by having designed the netted filtering of falling a funnel-form layer in the middle of the adnexa body easily, again effectively in the blocks air dust, microbe granular etc. enter air flue.By at adnexa upper end design one humidifying liquid guiding tube, can be used for the liquid introducing of humidifying.Link to each other with adnexa inwall flute profile annular groove in the humidifying liquid guiding tube, humidifying liquid can be taken advantage of a situation by this flute profile annular groove easily and be flowed to the netted filtering of falling the infundibulate layer that is attached to this ditch lower edge.Cross the netted filtering layer and be to central radial arrangement and slightly become infundibulate to declivity, be beneficial to humidifying liquid under action of gravity to central authorities' diffusion, thereby reach comprehensively the purpose that effective humidifying enters the air flue air.Open the aperture of the check valve sheet of a diameter 1cm in the central authorities of netted filtering layer,, be beneficial to the discharge of cough and sputum simultaneously so that lavage of trachea and sputum aspirator tube are inhaled expectorant.At conduit fitting bottom design one slight oblique downward oxygen access tube, be beneficial to through this conduit fitting oxygen supply.Design a connecting ring in the conduit fitting lower end, be beneficial to be connected with endotracheal tube.
In sum, the utility model proposes the endotracheal tube adnexa has dust in the blocks air, microbe granular etc. and enters the patient respiratory road, humidifying enters the air in the air flue, make things convenient for oxygen hose low discharge oxygen supply, the convenient advantages such as expectorant, convenient connection of inhaling, energy is many-sided to be improved because of problems behind the band behind the tracheostomy tube and deficiency.
Description of drawings
Fig. 1 is the structural representation of this endotracheal tube adnexa
Among the figure: 1 netted filtering layer, 2 humidifying liquid guiding tube, 3 sputum suction holes, 4 oxygen access tubes, 5 connecting rings, 6 adnexa bodys, 7 check valve sheet
The specific embodiment
Further specify structure of the present utility model below in conjunction with drawings and Examples:
As shown in Figure 1, the main body of endotracheal tube adnexa is a tubulose, is provided with the netted filtering of falling infundibulate layer 1 in the middle of adnexa body 6, and the dust in the blocks air, microbe granular etc. enter air flue effectively.The netted filtering of falling infundibulate layer 1 center forms infundibulate slightly downwards, and central authorities open the sputum suction hole 3 of a diameter 1cm, and sputum suction hole 3 has check valve sheet 7, so that lavage of trachea and sputum aspirator tube are inhaled expectorant, is beneficial to the discharge of cough and sputum simultaneously.Adnexa body 6 upper ends are connected with humidifying liquid guiding tube 2, humidifying liquid guiding tube 2 is taken advantage of a situation by the flute profile annular groove of adnexa inwall and is flowed to the netted filtering of falling the funnel-form layer 1 that is attached to this ditch lower edge, humidifying liquid imports the flute profile annular groove by humidifying liquid guiding tube 2, and the flute profile annular groove links to each other with the netted filtering of falling infundibulate layer 1, because the effect of gravity, humidification fluid will intersperse among on the netted filtering layer 1, thereby reach the purpose that humidifying enters the air flue air.In adnexa body 6 bottoms designs one oxygen access tube 4 below oblique is arranged, be beneficial to the importing of oxygen.Bottom design at adnexa body 6 has a ring-type connecting ring 5, is beneficial to and the tracheal intubation combination.
