Description
Technical Field
The utility model relates to the technical field of clinical medical equipment, in particular to a sputum-aspiration tracheostomy tube.
Background
Tracheotomy is a common operation of cutting the cervical trachea, putting a metal tracheal cannula or a silica gel cannula with an air sac into the tracheotomy to relieve dyspnea and respiratory dysfunction caused by laryngeal origin or lower respiratory tract secretion retention. After tracheotomy, the patient needs to be connected with a breathing machine through an autogenous cutting catheter to carry out mechanical ventilation, and when ventilation treatment is stopped, an air bag of the autogenous cutting catheter positioned in the trachea is deflated and temporarily kept in the trachea, and at the moment, the patient inhales air or oxygen through an autogenous cutting catheter opening. However, at present, when the patient's condition is improved and the tracheal catheter needs to be pulled out, two general clinical modes are adopted: firstly, directly pulling out and plugging and fixing the autogenous cutting wound by using a butterfly adhesive tape, and if the patient has repeated illness state and needs to carry out mechanical ventilation again, causing secondary tracheotomy and increasing the pain of the patient; secondly, before tube drawing, the tube is firstly plugged, namely, the opening of the tracheostomy tube is plugged by using a piston, and a patient finishes inspiration and expiration through the mouth and the nose, so that the risk of secondary incision is avoided, but the plugged trachea forms artificial airway stenosis because the tracheostomy tube is placed in the trachea, and thus, the patient can breathe very difficultly because of smaller gap, and discomfort of the patient is caused.
In summary, the prior art has the following disadvantages: when the sputum is sucked upwards, the sputum suction tube at the side of the sleeve is easy to be blocked (the secretion amount of the mouth and throat of a patient sinking onto the air bag is large, sticky or the granular and blocky foreign matters are sucked by mistake) due to the immobility and inextensibility of the sputum suction tube at the side of the sleeve, which easily leads to insufficient sputum suction and difficult sputum suction. Because of the irreplaceability of the sputum suction tube at the side of the sleeve, bacteria and viruses are easy to stay, bronchitis is caused, and the lung infection persists. The success rate of the gas pipe blocking cannot be improved. When the sleeve is blocked, the air flow can only enter and exit the main bronchus from the periphery of the sleeve.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a sputum-aspiration tracheostomy tube which solves the problems in the prior art. The sputum-aspiration tracheotomy tube can reduce the incidence rate of early lung infection of a tracheotomy patient and improve the success rate of tube blockage during the recovery period.
The sputum-aspiration tracheotomy tube comprises an outer tube, a tube core and an inner tube, wherein the tube core or the inner tube is arranged inside the outer tube;
the outer sleeve is characterized in that an air bag component is arranged at the outer part of the head end of the outer sleeve, a notch is formed in the outer corner end of the outer sleeve, a guide thorn head and a cover head are respectively connected with the head end and the tail end of the tube core, a notch plug is fixed at the outer corner end of the tube core, and the notch plug is spliced with the notch.
Preferably, the convex structure of the opening plug is matched with the concave structure of the opening.
Preferably, the air bag assembly comprises an air bag, an air bag tubule and an air bag interface, wherein the air bag is fixedly arranged with the outer sleeve, the air bag tubule is connected with the air inlet end of the air bag, and the air bag interface is connected with the tail end of the air bag tubule.
Preferably, the opening blocking head is made of silicon rubber.
Preferably, the guide spike is composed of silicone rubber.
Preferably, the cover head is inserted into the head end of the outer sleeve.
Preferably, the notch is an elliptic notch.
When the operation is performed on the patient, the tube core is matched with the outer sleeve, the operation is performed on the patient, the tube core is taken out after the operation is performed, and the outer sleeve is left on the patient. The air bag is inflated by the air bag connector and the air bag tubule, so that no gas flows out of a channel between the outer sleeve and the throat of a patient, the inner sleeve is inserted, and the patient breathes through the inner sleeve (at the moment, the inner sleeve and the outer sleeve are both inserted into the lung of the patient, and breathe directly through the inner sleeve during breathing).
When sputum is required to be sucked, a special additional sputum aspirator tubule is adopted to suck the sputum of the lung of the patient through the inner sleeve. If the sputum of the patient is positioned in the upper respiratory tract between the throat and the outer sleeve, the inner sleeve is taken out, the sputum aspirator tubule is inserted through the oval opening on the outer sleeve, and the sputum between the throat and the outer sleeve of the patient is sucked.
When the inner sleeve is required to be disinfected, the inner sleeve can be conveniently taken out for disinfection and then inserted into the outer sleeve for use. Avoid the integral type problem in the prior art that the long-term contact with sputum or the lung of a patient cannot be disinfected.
When the patient is recovering, the patient needs to be assisted to recover to breathe through the throat, and the orifice of the outer sleeve needs to be blocked. At this time, the inner sleeve is taken out first, the gas in the air bag on the outer sleeve is discharged, and then the mouth of the outer sleeve is blocked. In the prior art, the training of recovering throat respiration can only be carried out through the gap between the outer sleeve and the throat, and patients can breathe very difficultly due to the smaller gap. The outer sleeve is provided with the notch (the incision), so that the exhaled air of the lung can enter from the inside of the outer sleeve and enter the throat from the notch, thereby opening the air passage between the outer sleeve and the throat, and being beneficial to assisting the rehabilitation training of the patient in the rehabilitation stage.
The beneficial effects are that: this can inhale phlegm formula tracheotomy sleeve pipe makes medical personnel more convenient, standardized in clinical operation work absorb patient's oral cavity, throat portion sink to the secretion on the gasbag, reduces the incidence of pulmonary infection, and later stage stifled pipe (when the stifled pipe is that patient is recovered soon, in order to let patient resume normal breathing, blocks up the sleeve pipe, lets patient adapt to and resumes and breathe out from the throat) also can increase main tributary tracheal gas flow, reduces the air flue resistance, increases the possibility that stifled pipe was successful. The separated inner and outer sleeves are beneficial to disinfection of devices.
