The trachea cannula comprises a cannula body, an inflating sleeve bag and an inflating tube, and is characterized in that the cannula body consists of an outer tube, an inner tube, a plurality of connecting sheets and a joint; a gap is formed between the outer tube and the inner tube; the inner tube is fixedly connected with the outer tube through the connecting sheets which are integrally connected to the outer wall of the inner tube and are arranged along the axial direction; the lengths of the connecting sheets are not smaller than the length of the outer tube; the rear end of the outer tube is integrally connected with the joint; the outer diameter of the joint is greater than that of the outer tube; a shoulder of the joint is connected with an oxygen delivery tube; the front end of the inner tube extends out from the front end of the outer tube; the rear end of the inner tube penetrates in the joint and extends outwards; and a sputum sucking opening is formed in a side wall of the rear end of the inner tube. The trachea cannula is reasonable in design and easy and convenient to operate; the cannula can still be connected with auxiliary breathing equipment when sputum suction operation is performed; oxygen can be supplied for a patient when the sputum of the patient is sucked; various complications can be effectively prevented from being induced; and potential safety hazards on medical treatment are reduced.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to particularly a kind of tracheal intubation.
Background technology
Tracheal intubation is cardio-pulmonary resuscitation and with the important measures in the critical diseases rescue process of respiratory dysfunction, can effectively keep patient respiration road unobstructed, carries out effective oxygen supply, and the life that gives emergency treatment to a patient is played to vital effect.The tracheal intubation of existing clinical practice, carry out after the interior tracheal intubation of trachea, the normal trachea expectoration of patient is prevented from, and needs regularly row suction sputum operation, during suction sputum, tracheal intubation and assisted respiartion equipment need to be disconnected, by the opening part of tracheal intubation, stretch into sputum aspirator tube and carry out suction sputum operation, this complex operation, and when operation, patient can not get oxygen supply, easily bring out various complication, cause medical hidden danger.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple to operation, and while carrying out suction sputum operation, patient also can obtain the tracheal intubation of oxygen supply.
Task of the present utility model is achieved through the following technical solutions, comprise intubate, inflatable cuff 3, gas tube 4, its technical characterstic is that intubate is by outer tube 1 and inner tube 2, brace 5, joint 6 forms, between outer tube 1 and inner tube 2, there is gap, a plurality of braces 5 that arrange vertically that inner tube 2 connects by one on its outer wall are fixedly connected with outer tube 1, the length of brace 5 is not less than the length of outer tube 1, outer tube 1 rear end is connected with joint 6, the external diameter of joint 6 is greater than the external diameter of outer tube 1, the shoulder of joint 6 is communicated with oxygen catheter 7, the front end of inner tube 2 stretches out from the front end of outer tube 1, the rear end of inner tube 2 is protruding through joint 6, the sidewall of inner tube 2 rear ends is provided with suction sputum mouth 8.
The fore-end that inner tube 2 is stretched out outer tube 1 front end is soft pipe 21.
The triangle of the part that brace 5 stretches out outer tube 1 front end for progressively narrowing down, and the part that brace 5 stretches out outer tube 1 front end is soft 51.
A plurality of braces 5 are evenly distributed along inner tube 2 peripheries, effectively fixedly outer tube 1 and inner tube 2, and there is supporting role, and when being used, intubate is difficult for kinking distortion, and withstand voltage unimpeded.
On each brace 5, offer several through holes of arranging vertically 9.
Between outer tube 1 inwall of outer tube 1 top ends and inner tube 2 outer walls, be installed with screen membrane 10.
Good effect of the present utility model is: reasonable in design, simple to operation, carrying out suction sputum when operation does not need to disconnect being connected of intubate and assisted respiartion equipment, and operation while patient can obtain oxygen supply, effectively avoids bringing out various complication, reduces medical hidden danger.

The specific embodiment
Be described with reference to the accompanying drawings the details of a kind of tracheal intubation the utility model proposes.
As Fig. 1, Fig. 2, shown in Fig. 3, comprise intubate, inflatable cuff 3, gas tube 4, intubate is by outer tube 1 and inner tube 2, brace 5, joint 6 forms, between outer tube 1 and inner tube 2, there is gap, a plurality of braces 5 that arrange vertically that inner tube 2 connects by one on its outer wall are fixedly connected with outer tube 1, a plurality of braces 5 are evenly distributed along inner tube 2 peripheries, the length of brace 5 is not less than the length of outer tube 1, brace 5 is outer tube 1 and inner tube 2 effectively fixedly, and there is supporting role, this kind of intubate is difficult for kinking distortion while using, withstand voltage unimpeded, on each brace 5, offer several through holes of arranging vertically 9, gap between outer tube 1 and inner tube 2 is air supply channel, through hole 9 on brace 5 can guarantee that the circulation of oxygen in gap is not subject to the restriction of brace 5, oxygen enters trachea from annular air supply channel, the stimulation of the impulse force that can effectively cushion large flow oxygen uptake to patient's trachea mucosa, patient's tolerance, realize more effectively oxygen uptake, and from the body temperature of trachea and from inner tube 2 body temperature to external combustion gas, can continue the oxygen in the annular air supply channel of temperatureization, can reduce the stimulation of cold oxygen to air flue, reduce the incidence rate of air flue spasm, between outer tube 1 inwall of outer tube 1 top ends and inner tube 2 outer walls, be installed with screen membrane 10, screen membrane 10 can avoid trachea endocrine to enter air supply channel, guarantee the unimpeded of air supply channel, outer tube 1 rear end is connected with joint 6, the external diameter of joint 6 is greater than the external diameter of outer tube 1, make joint 6 also there is spacing effect, avoid intubate to insert trachea excessively dark, the shoulder of joint 6 is communicated with oxygen catheter 7, the front end of inner tube 2 stretches out from the front end of outer tube 1, the fore-end that inner tube 2 is stretched out outer tube 1 front end is soft pipe 21, the part that brace 5 stretches out outer tube 1 front end is the triangle progressively narrowing down, and the part that brace 5 stretches out outer tube 1 front end is soft 51, adopt inner tube 2 front ends and leg-of-mutton brace 5 front ends of soft material, can avoid the damage of intubate to patient respiration road mucosa, improve the safety of its use, alleviate patient's misery, also can reduce the difficulty of putting pipe, facilitate medical personnel to put pipe operation, the rear end of inner tube 2 is protruding through joint 6, the sidewall of inner tube 2 rear ends is provided with suction sputum mouth 8, while needing suction sputum, mouthful connection sputum aspirator operation thus, while needing humidifying trachea, also a mouthful connection humidification device carries out humidifying operation thus, do not need suction sputum, during humidifying operation, can be by 8 sealings of suction sputum mouth.
