Abstract

This utility model embodiment proposes a kind of endotracheal tube, comprises the catheter body that external diameter is less than trachea, and described catheter body has the link being inserted into insertion end in trachea and far-end; Described catheter body is provided with the pressure bladder of the inflatable hermetic seal for sealing gap between described catheter body outer wall and trachea near the periphery of described insertion end, hermetic seal between the outer wall of described pressure bladder and described catheter body; And described catheter body periphery is also provided with the positioning gasbag of the hermetic seal for controlling described catheter body insertion depth, hermetic seal between the outer wall of described positioning gasbag and described catheter body.Like this can after catheter body insert glottis, limit by positioning gasbag the degree of depth that catheter body inserts, can prevent from inserting dark or excessively shallow.Also comprise inflatable pressure bladder simultaneously, can be pressure bladder inflation after catheter body is inserted completely like this, to seal the space between trachea and catheter body, prevent gas leakage or catheter body from coming off.

Description

One can locate mode endotracheal tube
Technical field
this utility model relates to technical field of medical instruments, particularly has the endotracheal tube of positioning gasbag and pressure bladder.
Background technology
endotracheal tube is the indispensable medical apparatus and instruments of endotracheal intubation.Endotracheal tube is inserted into from the mouth of patient tracheal strips with by auxiliary facilities assisted respiartion clinically, it is cardio-pulmonary-cerebral resuscitation and with the important measures in patient's rescue process of respiratory dysfunction, also be the safety measure implementing anesthesia, be widely used in multiple medical domain such as first aid, operation.Existing endotracheal tube intubation needs just can complete through the experienced Anesthetist of professional training or nurse, and is easy to cause the failure of conduit tracheal intubation without professional training or the health care worker of lacking experience for section office such as basic hospital, internal medicine, surgery, department of pediatrics, obstetrics, emergency departments.Meanwhile, for after tracheal intubation during changing position, or implement first aid in the wild and pass in process, also often can cause the failure of conduit tracheal intubation.If conduit inserts too dark or is strayed in a laterobronchus; Mucosa injury can be caused, as a series of complication such as pneumothorax, hypoventilation, anoxia pulmonary atelectasis.If conduit inserts too shallow, can cause surprisingly deviating from when patient posture variation or carrying, cause seriously unexpected generation.Therefore whether suitable endotracheal tube insertion depth is plays vital effect in the critical heavy patient procedure of rescue.
Utility model content
the purpose of this utility model be in order to propose a kind of can prevent endotracheal tube inserted dark or excessively shallow can locate mode endotracheal tube.
in order to solve the problem, this utility model embodiment proposes one can locate mode endotracheal tube, comprises the catheter body that external diameter is less than trachea, and described catheter body has the link being inserted into insertion end in trachea and far-end; Described catheter body is provided with the pressure bladder of the inflatable hermetic seal for sealing gap between described catheter body outer wall and trachea near the periphery of described insertion end, hermetic seal between the outer wall of described pressure bladder and described catheter body; And described catheter body periphery is also provided with the inflatable positioning gasbag for controlling described catheter body insertion depth, hermetic seal between the outer wall of described positioning gasbag and described catheter body.
wherein, also comprise pressure bladder valve, described pressure bladder valve by flexible hose and described pressure bladder conducting to control described pressure bladder inflation/deflation.
wherein, described positioning gasbag is the inflatable bladder type positioning ring being socketed in described catheter body periphery.
wherein, also comprise positioning gasbag valve, described positioning gasbag valve by flexible hose and described positioning gasbag conducting to control described positioning gasbag inflation/deflation or charge and discharge liquid.
the technical solution of the utility model has following advantage: such scheme proposes one can locate mode endotracheal tube, and it has and comprises positioning gasbag and inflatable pressure bladder.After catheter body can being inserted glottis in catheter manipulation process like this, limited the degree of depth of catheter body insertion by positioning gasbag.After the positioning gasbag inflation of catheter body, just cannot continue insertion, can prevent from inserting dark or excessively shallow.Also comprise inflatable pressure bladder simultaneously, can be pressure bladder inflation again after catheter body inserts suitable position like this, to seal the space between trachea and catheter body, prevent gas leakage or catheter body from coming off.
Accompanying drawing explanation
by the description carried out a preferred embodiment of the present utility model below in conjunction with accompanying drawing, the technical solution of the utility model and technique effect thereof will become clearly, and easy to understand more.Wherein:

7: positioning gasbag valve.
Detailed description of the invention
below with reference to appended accompanying drawing, a preferred embodiment of the present utility model is described.
below in conjunction with accompanying drawing, this utility model embodiment is further described.The endotracheal tube of this utility model embodiment as shown in Figure 1, comprises the catheter body 1 that external diameter is less than trachea, and described catheter body 1 has the link 3 being inserted into insertion end 2 in trachea and far-end.As shown in Figure 1, catheter body 1 is provided with the pressure bladder 4 of the inflatable hermetic seal for sealing gap between described catheter body 1 outer wall and trachea near the periphery of described insertion end 2, hermetic seal between described pressure bladder 4 and the outer wall of described catheter body 1.As shown in Figure 1, described catheter body 1 periphery is also provided with positioning gasbag or the liquid capsule of the hermetic seal for controlling described catheter body 1 insertion depth, hermetic seal between the outer wall of described positioning gasbag or liquid capsule and described catheter body.
as shown in Figure 1, also comprise pressure bladder valve 6, described pressure bladder valve 6 by flexible hose and described pressure bladder conducting to control described pressure bladder 4 inflation/deflation.Because pressure bladder is not inflated condition at ordinary times, catheter body can be facilitated like this to be inserted into tracheal strips.And can be pressure bladder inflation by pressure bladder valve after conduit, prevent the gap air leak between catheter body and trachea, and can prevent catheter body from coming off.
as shown in Figure 1, described positioning gasbag is the inflatable bladder type positioning ring 5 being socketed in described catheter body periphery.Adopting inflatable structure, is can not block vision or stop when catheter body is inserted.And the more complete ring of row after positioning gasbag inflation is pushed ahead the effect playing location after smoothly inserting glottis, when being inserted into desired depth, positioning gasbag will snap into glottis place, prevents from inserting dark or excessively shallow.As shown in Figure 1, also comprise positioning gasbag valve, described positioning gasbag valve is charged and discharged gas or liquid to control described positioning gasbag by flexible hose and described positioning gasbag conducting.
for person of ordinary skill in the field, along with the development of technology, this utility model design can realize by different way.Embodiment of the present utility model is not limited in embodiment described above, and can change within the scope of the claims.
