Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The technical solution of the present invention will be described in detail with reference to the accompanying drawings.

Respiratory track spreads disease with breathing return circuit, including crossover sub 2, it has intubate 3 to extend with 1 machine end relative crossover sub 2 an organic whole of trachea cannula, and 3 mouth of pipe interpolation cover of intubate have isolated sleeve 4, and the bottom of isolated sleeve 4 is opened has can wear to put and inhales phlegm pipe be criss-cross slot 5, the fork portion of criss-cross slot 5 is three at least, and terminal surface and 3 mouth of pipe terminal surfaces of intubate end stop cooperation under the outside lower outer fringe that extend formation in top of

isolated sleeve

4, 3 mouths of pipe of intubate be equipped with isolated sleeve 4's the spacing complex sealing ring 8 in lower outer fringe, be equipped with on the sealing ring 8 with the sealed lid 6 of the sealed complex of 8 mouths of sealing ring.

When secretion in the respiratory tract of a patient needs to be removed, medical staff do not need to pull out the adapter 2 and open the sealing cover 6, the blocking effect of the isolation sleeve 4 is achieved, and the secretion of the patient is sprayed out and cannot splash to the face of the medical staff; when the sputum suction tube is inserted into the slot 5 of the isolation sleeve 4, the fork part at the intersection of the slot 5 is closely matched with the sputum suction tube, and when the sputum suction tube passes through the slot 5 to discharge the secretion, the secretion of the patient is sprayed out and cannot splash to the face of the medical staff due to the isolation sleeve 4 between the sputum suction tube and the insertion tube 3; medical staff draws away and inhales the phlegm pipe, and crack 5 resumes to initial closed condition, with sealed lid 6 lock to sealing ring 8 on can, can be isolated mutually with patient's larynx intraduct environment and external environment like this. Therefore, in the present invention, the isolation sleeve 4 is preferably made of a flexible material (e.g., rubber or silicone material). The cross-shaped slits 5 may have three fork portions, four fork portions as shown in fig. 4, or a larger number of cross-shaped portions. In order to enable the sealing between the sealing cover 6 and the sealing ring 8 to be tight, the sealing cover 6 and the sealing ring 8 are preferably made of silicone materials. Preferably, as shown in fig. 3, the sealing ring 8 has an annular stepped structure inside.

In order to improve the isolation performance of isolation sleeve 4, with patient's larynx internal environment with external isolated, the bottom of isolation sleeve 4 remains and is the forked arris portion 14, what the forked gap 5's of crossing fork portion corresponds respectively is located arris portion 14 on, and the junction of adjacent arris portion 14 is upwards sunken to be established along the central line of adjacent arris portion 14 and is formed two pressure-bearing inclined planes 15. The patient is at the respiratory in-process, and the respiratory track can produce secretion such as sputum, and the secretion can be ejected along with the gas and the aerosol of patient's exhalation, and the power that the secretion sprays to form can be used in pressure-bearing inclined plane 15, and pressure-bearing inclined plane 15 produces the power towards slot 5 for slot 5 butt joint on the arris portion 14 is inseparabler, and the effectual secretion of avoiding passes through slot 5 and gets into isolated sleeve 4 top space.

During specific implementation, the endotheca has the sleeve 10 of ending in isolated sleeve 4, and the bottom of ending sleeve 10 is radius platform structure, and it has the hole 12 of wearing to put and inhale the phlegm pipe to open at radius platform structure middle part, and interval between radius platform structure and the bottom of isolated sleeve 4 can avoid from supreme down taking away inhales behind the phlegm pipe arris portion 14 and pressure-bearing inclined plane 15 enstrophe to isolated sleeve 4 in, the cooperation of ending with isolated sleeve 4's lower outer fringe up end of terminal surface under the last outer fringe that the top of ending sleeve 10 outwards extended the formation. Specifically, the stop sleeve 10 may be made of a hard material or a flexible material. The stop sleeve 10 is preferably made of a flexible material (such as rubber or silica gel), and the through hole 12 is in interference fit with the sputum suction tube.

In specific implementation, the machine end of the adapter 2 is integrally formed or detachably sleeved with an artificial nose 7 (as shown in fig. 2). When the critical patient is relieved, the disposable breathing circuit 13 is directly pulled out to observe the condition of the patient in order to test that the patient can be separated from a breathing machine or an anesthesia machine to realize autonomous breathing. The artificial nose 7 can collect and retain heat and water vapor in the exhaled air, and the air is brought into the air passage in a warm and humid state through the artificial nose 7 during inhalation, so that the air passage is ensured to be effectively and properly humidified, meanwhile, the artificial nose has a good filtering effect on microorganisms such as bacteria and viruses, and the danger that pipelines and breathing machines or anesthesia machines are polluted by harmful microorganisms can be reduced. In specific implementation, when the artificial nose 7 is of a detachable sleeve structure and a patient cannot be separated from a breathing machine or an anesthesia machine, the artificial nose 7 is detached, and the machine end of the adapter 2 is in inserted fit with the disposable breathing loop 13; after the patient's state of illness is relieved, the disposable breathing circuit 13 is pulled out, and the artificial nose 7 is inserted.

Further, a carbon dioxide interface 11 is arranged on the outer side of the machine end of the artificial nose 7. The gas sample is convenient to extract for monitoring carbon dioxide. When the carbon dioxide monitoring device is used specifically, the carbon dioxide interface 11 is sleeved with a cover body in interference fit with the carbon dioxide interface 11, and when the carbon dioxide is required to be monitored, the cover body is pulled out. The cover body can be made of elastic materials such as rubber or silica gel, and the cover body is convenient to be tightly matched with the carbon dioxide interface 11.

Specifically, the inner circle of the sealing ring 8 is in clearance fit with the sputum suction tube, and a plug body 9 in interference fit with the inner circle of the sealing ring 8 is arranged in the sealing cover 6. This further avoids the influence of secretions in the patient's respiratory tract on the air environment of the medical site.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
