Abstract
The utility model relates to a straight trachea cannula which comprises a hollow cannula and a fixing ring, wherein the hollow cannula is a cylindrical silicone tube, an integrated external thread is arranged on the hollow cannula body, a linear type flap of foot is arranged at one end of the hollow cannula, the angle between the flat surface of the flap of foot and the axle wire of the hollow cannula is 60 degrees, the fixing ring is a silicone ring, and the fixing ring can sleeved on the external of the hollow cannula. The straight trachea cannula has the advantages that the straight trachea cannula overcomes the defects of an existing trachea cannula, the linear type flap of foot located at one end of the cannula and the thread located on the cannula body prevent the cannula from slipping out of the fixing ring, a trachea is not blocked and the aeration of the trachea is not affected because almost no foreign matter is in the trachea after the cannula being inserted in the trachea, the histocompatibility is good and inflammation of a cut is not caused because the cannula is made of novel silicone materials, absorption of sputum is convenient, nursing is convenient because the inner cannula need not to be cleaned, and pharyngalgia does not occur and food-taking is not affected because the contact area between the cannula and the trachea is small.
Description
Technical field
This utility model relates to medical instruments field, specifically, is a kind of straight tracheal casing pipe.
Background technology
Tracheotomy is a kind of emergent operation that rescues the critical illness people, is the pars cervicalis tracheae antetheca is cut, and by otch suitable big or small sleeve pipe is inserted trachea, and patient can directly be breathed through sleeve pipe.Sometimes also can be used as go down patient's important auxiliary treatment means of some long-term coma, respiratory function.
Adopt curved formula sleeve pipe clinically at present, but curved formula sleeve pipe often has following shortcoming: stimulate tunica mucosa tracheae, cause secretions increase more; The wearing and tearing tracheal wall causes the trachea perforation; The damage innominate artery causes massive hemorrhage; Affect the tube chamber ventilation; Perishable being broken into of sleeve pipe is foreign body in trachea; Need the cleaning inner sleeve, the nursing trouble.
Summary of the invention
The purpose of this utility model is that a kind of straight tracheal casing pipe is provided.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of straight tracheal casing pipe, described straight tracheal casing pipe comprises hollow sleeve and retainer ring, described hollow sleeve is the cylindrical shape silica gel tube, pipe shaft is provided with integrated external screw thread, and an end of described hollow sleeve is provided with linear type lobe foot, and the plane of described lobe foot and the axis of hollow sleeve are 60 ° of angles, described retainer ring is the silica gel annulus, can be enclosed within the outside of hollow sleeve.
Described straight tracheal casing pipe also comprises a silica gel shutoff plug, and described shutoff plug is cylindric or round table-like, can fill in the mouth of pipe of hollow sleeve.
Described hollow sleeve external diameter is 11mm.
Described retainer ring external diameter 20mm, internal diameter 10mm.
This utility model advantage is:
Straight tracheal casing pipe of the present utility model has been eliminated the in the past multiple shortcoming of tracheal casing pipe, and the lobe foot of mouth of pipe straight line and the screw thread of pipe shaft can prevent that sleeve pipe from deviating from; Basic foreign in the trachea does not block trachea after the intubate, does not affect ventilation; Sleeve pipe adopts the novel silica gel material, and histocompatibility is good, does not cause the otch inflammation; Make things convenient for suction sputum; Do not need to clean inner sleeve, nursing is convenient; Sleeve pipe and trachea contact area are few, do not cause pharyngalgia, do not affect feed.
Description of drawings
Accompanying drawing 1 is the structural representation of straight tracheal casing pipe of the present utility model.
The specific embodiment
Below in conjunction with embodiment and with reference to accompanying drawing this utility model is further described.
The Reference numeral and the ingredient that relate in the accompanying drawing are as follows:
1. hollow sleeve 2. retainer rings
3. shutoff plug 11. lobe feet
12. external screw thread
Please refer to accompanying drawing 1, accompanying drawing 1 is the structural representation of straight tracheal casing pipe of the present utility model.Described straight tracheal casing pipe comprises hollow sleeve 1 and retainer ring 2, described hollow sleeve 1 is the cylindrical shape silica gel tube, external diameter is 11mm, pipe shaft is provided with integrated external screw thread 12, one end of described hollow sleeve 1 is provided with linear type lobe foot 11, and the axis of the plane of described lobe foot 11 and hollow sleeve 1 is 60 ° of angles.The lobe foot 11 of described straight line and the external screw thread 12 of pipe shaft can prevent from deviating from when hollow sleeve 1 from using.Described retainer ring 2 is silica gel annulus, external diameter 20mm, internal diameter 10mm.Can be enclosed within the outside of hollow sleeve 1 during use, be used for fixedly hollow sleeve.
Need to prove that described straight tracheal casing pipe also comprises a silica gel shutoff plug 3, described shutoff plug 3 is cylindric or round table-like, can fill in the mouth of pipe of hollow sleeve 1.During use, with shutoff plug 1 a period of time of 3 shutoff hollow sleeves, if the patient can eupnea, then can pull out tracheal casing pipe.
Clamp two lobe feet 11 with vascular forceps during use, acute angle is upwards inserted in the intratracheal fistula mouth, have break through sense after, unclamp vascular forceps, outside tractive gently stops after feeling to have resistance, then is inserted in outside silica gel solid fixed ring 2, inwardly slips into to prevent hollow sleeve 1.
Straight tracheal casing pipe of the present utility model has been eliminated the in the past multiple shortcoming of tracheal casing pipe, and the lobe foot of mouth of pipe straight line and the screw thread of pipe shaft can prevent that sleeve pipe from deviating from; Basic foreign in the trachea after the intubate, little to the stimulation of trachea, cough reflex reduces; Do not block trachea, do not affect ventilation, be beneficial to gas by normal anatomical airway, promote the functional rehabilitation of normal anatomy air flue; Sleeve pipe adopts the novel silica gel material, and histocompatibility is good, does not cause the otch inflammation; Make things convenient for suction sputum; Do not need to clean inner sleeve, nursing is convenient; Sleeve pipe and trachea contact area are few, do not cause pharyngalgia, do not affect feed.
Straight tracheal casing pipe result of use of the present utility model is good, and it is more applicable particularly need to be worn the patient of pipe for a long time.Airway constriction behind the operation in patients after straight sleeve pipe is used in transition before tube drawing, can successfully be pulled out tracheal casing pipe, and good application prospect is arranged.
This utility model is worn tracheal casing pipe patient's treatment to long-term need, and safer, reliable assurance has been arranged.Healing the sick the production creation of the wealth of society more is unable to estimate, is to the innovation of tracheotomy tracheal casing pipe revolution, belongs to domestic initiation, is the significant contribution of China's autonomous innovation.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this utility model principle; can also make some improvement and replenish, these improvement and replenish and also should be considered as protection domain of the present utility model.
