Description

Tracheal cannula assembly

Technical Field

The embodiment of the application relates to a medical apparatus, in particular to an endotracheal intubation component for preventing the splash pollution of the airway of a patient.

Background

The transmission route of the strong infectious diseases such as SARS, Ebola hemorrhagic fever, new coronary pneumonia Virus (Corona Virus) and the like which are outbreaked all over the world is mainly through respiratory droplets and contact. For example, the new coronavirus is treated by supportive treatment, and the treatment course is high oxygen flow treatment or noninvasive ventilator; if a noninvasive ventilator is not used for two hours, the trachea is intubated. However, each step of tracheal intubation for critical patients has a precondition and a corresponding standard. The hardware is matched, the precondition for trachea intubation is that a laminar flow ward is needed, and the medical care ratio after intubation reaches 1: 2-3. The current situation is that under the condition that the number of patients is large, the number of multi-layer flow wards of a hospital is very limited, and more patients cannot be accommodated. If the hardware set is lacked, all doctors and nurses are very likely to be infected. In the sputum aspiration process, droplets are sprayed out when a patient is stimulated to cough. After the patient is intubated, the patient can continuously spray new coronavirus droplets for 24 hours, and the air in the whole room can be polluted.

The existing isolation and protection articles for patients exist, the anti-splashing isolation towel used in some intensive care units is spliced by soft transparent plastic and an operation towel, the periphery of the isolation and protection articles is pasted by an adhesive tape, the sputum suction process is realized by a bedside tracheal cannula, the splashing can be really avoided, the risk of exposure infection is reduced, the instrument in the operation process of the cannula cannot be avoided, the risk of aerosol infection is inevitable, the operation space and the visual field of an operator are greatly influenced, and the cooperation operation of a plurality of people is difficult.

The whole cover is made of hard plastic or pipe, a diaphragm operating window is arranged around a patient, the upper half or the whole body is occupied, the occupied space is large, the mass production, the storage and the transportation are difficult, the problems of insufficient light transmission, low cyclic utilization rate and the like exist, the sealing performance of the diaphragm is poor, and the virus transmission is still possible.

CN201333146Y discloses a separate nursing cover, which has limited observation and nursing, and is difficult to change the original operation habit of the operator in order to perform the operation, and the usability is poor.

Patent No. CN209643938U discloses a splash-proof mask special for bronchoscopy, which comprises a mask, a fixed elastic band and a hair-care piece; the left end and the right end of the face mask are fixedly connected with fixed elastic bands, and the fixed elastic bands and the two sides of the face mask form a closed ring shape; the upper side of the face mask is fixedly connected with a hair-protecting piece, the center position of the face mask is fixedly provided with a nose-shaped opening which penetrates through the front and the back, and the front side of the nose-shaped opening is fixedly provided with a nose-shaped bulge. But the structure is complex, the operation is inconvenient, and the use of the fixed elastic band can cause indentation to patients.

Therefore, an endotracheal intubation which is convenient to operate is urgently needed, so that the virus of a patient is prevented from being transmitted to medical staff through respiratory droplets and aerosol, and the operations of the medical staff such as operation and nursing are not influenced.

The sealingring 103 may provide a cushion when theouter insert 105 is inserted into thesocket 102, further preventing the patient from splashing of breath such as spray, aerosol, etc. As shown in fig. 8 and 9, in an embodiment of the present application, thesocket 102 may be arranged coaxially with the sealingring 103, i.e. the center point of thesocket 102 coincides with the center point of the sealingring 103. As shown in fig. 10 and 11, in an embodiment of the present application, thesocket 102 may be arranged eccentrically to thesealing ring 103, i.e. the center point of thesocket 102 is not coincident with the center point of the sealingring 103. This off-center arrangement further facilitates insertion of theouter insert 105 into thesocket 102 and also further facilitates prevention of spray spillage.

Theendotracheal tube assembly 200 may also include a pair of nasal prongs (not shown) that are connected to thepatch 101, such as by a connecting wire. During operation, the nasal plug can be plugged into the nostril of a patient to prevent the nasal plug from breathing out spray, aerosol and the like through the nostril.

In another embodiment of the present application, as shown in fig. 13 to 14, theendotracheal tube assembly 200 may further include atooth holding unit 106 connected to thepatch 101. In this embodiment, thetooth holding unit 106 includes: anupper tooth support 106a for supporting upper teeth; alower tooth support 106b for supporting a lower tooth, thelower tooth support 106b being connected to theupper tooth support 106a and forming agap 107, thegap 107 corresponding to thesocket 102. When theflexible sealing cover 104 is opened when subjected to an external squeezing force, and theflexible sealing cover 104 is tightly fitted with theexternal insert 105 inserted into the socket, theexternal insert 105 penetrates thefilm 101 into thegap 107 and further into the airway of the patient. The upperdental support 106a has two end portions, and the lowerdental support 106b has two end portions. The oral cavity holding device of this application can effectively fix patient's tooth in the operation such as trachea cannula, panonychomycosis puncture, tracheotomy, phlegm suction, prevents that the patient from stinging outside plug-in components.

As shown in fig. 14, in an embodiment, the two end portions of the upper supportingmember 106a and the lower supportingmember 106b are connected to form an included angle smaller than 90 °, and a space sandwiched between the two end portions of the upper supportingmember 106a and the lower supportingmember 106b forms agap 107. The upper and lowerdental supports 106a and 106b are fixedly or non-fixedly attached to thefilm 101, and thefilm 101 is positioned over thegap 107 to seal the patient's gums.

In another embodiment, the upperdental support 106a and the lowerdental support 106b are connected at two ends to form an annular cylinder, and the inner space surrounded by the annular cylinder forms agap 107. The upperdental support 106a may extend alength 106 a' relative to the lowerdental support 106b for depressing the tongue to prevent a hypertrophic tongue from accumulating at the epiglottis and blocking ventilation.

In an embodiment of the present application, when thecannula 201 is inserted, thefilm 101 is attached to the mouth and nose of the patient to close the mouth and nose, thetooth holding unit 106 is used to fix the upper teeth and the lower teeth, the external plug-incomponent 105 is inserted into thegap 107 formed by the uppertooth supporting component 106a and the lowertooth supporting component 106b, and then the external plug-in component sequentially enters the mouth and airway of the patient, so as to perform the operation on the patient.

To sum up, the trachea cannula subassembly of this application can effectively cover patient's mouth and nose, keeps apart droplet, aerosol, avoids because of carrying out trachea cannula, cricothyroid membrane puncture to patient, and the trachea is cut, is inhaled phlegm etc. and has invasive operation and take place droplet, aerosol infection.
