Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a indwelling closed type safe plastic autogenous cutting sleeve device.
Background
A portion of patients in the clinic receive tracheotomies and leave an autogenous cutting cannula for a variety of reasons. The patients may need to unplug the autogenous cutting sleeve to recover the state of normal oral-nasal ventilation due to the following condition. While long-term indwelling of the tracheostomy tube may cause post-tracheostomy narrowing associated with various reasons, such as glottic or subglottal edema, localized scar narrowing, localized granulation, tracheal collapse due to cartilage damage, localized ulcers or necrosis, and the like. The narrow trachea of a small proportion of tracheotomy patients is very hidden and difficult to find before extubation. Relevant reports suggest that factors such as obesity, unresponsiveness, communication disorders and the like of patients are more likely to cause hidden tracheal stenosis conditions which are difficult to find by doctors. Thus, when the tracheostomy tube is removed conventionally, the patient is subsequently subjected to acute dyspnea or even choking for further rescue, and the raw gas incision is reduced or closed by the removal of the tracheostomy tube. At the same time, patients with this hidden symptom often combine difficult intubation with numerous underlying diseases, resulting in increased difficulty in emergency rescue and increased risk of accidental choking.
Disclosure of Invention
In order to overcome the problems, the invention provides a safe plastic autogenous cutting sleeve device capable of being kept in a closed mode.
The technical scheme adopted by the invention is as follows: the utility model provides a can keep somewhere closed safe plastics autogenous cutting sleeve pipe device, includes flexible autogenous cutting sleeve pipe, and flexible autogenous cutting sleeve pipe inner chamber is equipped with the inner core that is used for supporting flexible autogenous cutting sleeve pipe, and the lower extreme of inner core is bullet shape and opens has the air vent, flexible autogenous cutting sleeve pipe inserts and establishes in subcutaneous tunnel main body structure, and flexible autogenous cutting sleeve pipe's upper end is equipped with the turn-ups of hanging with subcutaneous tunnel main body structure cooperation;
The main structure of the subcutaneous tunnel comprises a tube body sleeved outside the flexible autogenous cutting sleeve pipe, a fixing wing is arranged at the upper end of the tube body, and the fixing wing is attached to the neck of a human body and externally fixes the main structure of the subcutaneous tunnel; the lower end of the pipe body is provided with a butterfly wing fixing device, and the butterfly wing fixing device comprises a folding rod, a pull ring and a traction rope; the folding rod consists of a first supporting rod and a second supporting rod, the end parts of the first supporting rod and the second supporting rod are mutually hinged, the upper end of the first supporting rod is connected with the lower end of the pipe body, the lower end of the second supporting rod is connected with a pull ring, and the pull ring is sleeved outside the flexible autogenous cutting sleeve; the traction rope is connected to the pull ring and passes through the fixed wing upwards; pulling the hauling rope upwards, lifting the pull ring to enable the folding rod to be unfolded outwards to form a butterfly wing-shaped buckle structure, and remaining the butterfly wing-shaped buckle structure in the tracheal cavity of a human body to fix the main body structure of the subcutaneous tunnel internally so as to prevent the main body structure of the subcutaneous tunnel from slipping and shifting; and the traction rope is loosened, and the folding rod slides downwards to be retracted and is folded at the outer side of the flexible autogenous cutting sleeve pipe.
Further, two folding rods are symmetrically arranged about the axis of the pipe body, and a traction rope is respectively arranged at the joint of each folding rod and the pull ring.
Further, the upper end of the pipe body is symmetrically provided with a pair of fixing wings about the axis of the pipe body.
Further, the subcutaneous tunnel main body structure is provided with a removable subcutaneous tunnel sealing plug, and the removable subcutaneous tunnel sealing plug is plugged into and tightly matched with the upper end pipe orifice of the subcutaneous tunnel main body structure so as to seal the subcutaneous tunnel main body structure after the subcutaneous tunnel main body structure is kept.
Furthermore, the removable subcutaneous tunnel sealing plug is made of silica gel.
Further, a connecting port matched with the port of the breathing machine is arranged at the pipe orifice at the upper end of the flexible autogenous cutting sleeve pipe.
Further, the flexible autogenous cutting sleeve pipe is made of plastic materials.
Further, the inner core is made of hard plastic.
The beneficial effects of the invention are as follows:
(1) Aiming at the high-risk suffocation group needing to pull out the autogenous cutting sleeve pipe in clinic, the butterfly wing fixing device is innovatively added on the conventional autogenous cutting sleeve pipe device. When the patient pulls out the autogenous cutting sleeve pipe, keep somewhere the haulage rope in vitro through the traction, open butterfly wing appearance internal fixation device, can be fixed in the trachea intracavity with subcutaneous tunnel, remain patient's urgent breathing passageway, very big improvement the security after this kind of crowd pulls out the pipe to provide the breathing passageway for the rescue that later stage probably appears. Can be applied to almost all people who need to pull out the autogenous cutting sleeve in clinic, and has simple and convenient operation and easy operation.
(2) The balloon air leakage prevention device of the traditional autogenous cutting sleeve pipe is abandoned creatively, and the reason is as follows: the balloon air leakage prevention device of the traditional autogenous cutting sleeve pipe mainly aims at guaranteeing effective and sufficient ventilation when a patient receives treatment of a breathing machine. The presence of the balloon can prevent the autogenous cutting cannula from entering the main body structure, making placement of the autogenous cutting cannula difficult during rescue. In addition, almost all people who need to pull out the autogenous cutting sleeve pipe have the state of illness relatively steady, only need to open the gassing incision again just can solve the dyspnea problem, do not meet the demand of breathing machine treatment. Therefore, the invention abandons the design of the saccule, so that the clinical practicability is improved, and the clinical operation is more rapid and convenient.
