Description
Technical Field
The utility model belongs to the technical field of medical instrument, specifically be an adjustable trachea opens blocking up ware.
Background
Tracheotomy is an important emergency treatment measure for keeping the respiratory tract unobstructed and improving the breathing of critically ill patients in clinic. It is often used for patients with cerebral hemorrhage, cerebral infarction, myasthenia gravis, respiratory failure, and motor neuron disease. After the patient's condition is improved, in order to reduce the occurrence of complications, the tracheal cannula needs to be pulled out as soon as possible to recover the patient's vocal function and the normal physiological function of the airway. When the patient who implements the tracheotomy state of an illness is stable and allows to pull out tracheal cannula, generally try earlier stifled pipe before pulling out the pipe, resume normal air flue mode of ventilating, safe effectual examination stifled pipe is very important before pulling out the pipe. In the prior technical scheme, the conventional clinical common tracheal cannula blocking device comprises a wooden plug, a rubber bottle plug, a Murphy dropper of an infusion apparatus and the like, has the defects of easy expectoration, easy aspiration, difficult disinfection and repeated manufacture, is easy to cause pollution, brings inconvenience to the tracheal blocking process, and even causes failure or infection of the blocked tracheal cannula; when the wooden plug and the rubber plug are used for plugging the tube, the half plugging process is lacked, the partial pressure is completely plugged and the symptoms such as difficult breathing are reduced, and the sputum suction and oxygen suction operation is inconvenient during the tube plugging period; in addition, it can increase the discomfort and tension of the patient, which can be detrimental to the effective performance of the treatment.
Because the tracheotomy belt tube is long in time, the tracheotomy sleeve is directly pulled out, and partial patients can have the problems that the tracheotomy fails to be suitable for mouth and nose breathing and the tube needs to be replaced; even partial patients suffer from trachea collapse after direct extubation, resulting in suffocation and even death of the patient. In view of the above two points, before tube drawing, it is necessary to perform tube trial blocking to some extent, that is, gradually block the open end of the tracheostomy cannula exposed outside the human body, for example, 1/4 tube blocking is performed at the beginning, 1/2 tube blocking is performed again after no breathing difficulty of the patient within 24 hours, the patient is continuously observed, 3/4 tube blocking is performed again after no breathing difficulty of the patient within 24 hours, and so on until the patient breathes stably within 24 to 48 hours after the tube is completely blocked, and the physician can be informed to perform tube drawing.
There have been many attempts in practice to achieve a graduated change in the trial plugging operation. For example, chinese patent No. CN208481835U discloses a disposable tracheotomy humidification filter tube plugging device, which comprises a tube plugging device cylinder, a top end of the tube plugging device cylinder is provided with a plugging cover, the plugging cover and the tube plugging device cylinder are rotationally matched, a rotating shaft is arranged on a side of a central hole of the tube plugging device cylinder, and an axis of the rotating shaft is parallel to a central axis of the tube plugging device cylinder; the filter screen is arranged in the tube body of the tube blocking device. The side wall of the pipe blocking device barrel is provided with a humidifier interface communicated with a central hole of the pipe blocking device barrel, the humidifier interface is arranged above the filter screen, and the outer end of the humidifier interface is provided with a cover cap. The side wall of the tube plugging device cylinder is provided with an air bag communicated with the central hole of the tube plugging device cylinder. The utility model discloses when conveniently realizing half stifled pipe and full stifled pipe, can prevent that foreign matter, dust etc. from getting into the tracheal cannula, conveniently carry out the humidifying to the air, provide a better respiratory environment condition for the patient. The breathing condition of the patient can be observed through the opening and closing condition of the air bag, for example, the breathing difficulty condition of the patient can be found in time. The change of the degree of blockage of the device is realized by a blocking cover which can be biased, and the mode has the defects that in the case of semi-blocked tube, the deflection of the blocking cover increases the actual using space of the device and increases the possibility of causing secondary injury to the tracheotomy of the patient due to mistaken touch; in addition, the device is not provided with a heat-preservation and moisture-preservation structure, so that the heat-preservation and moisture-preservation effect is poor and infection is easily caused, and the recovery of a patient is not facilitated.
