Abstract
The utility model discloses a kind of tracheostomy cannulas and closed endotracheal suction pipe connecting structure, including external connector, end cover nut and incision of trachea casing joint, external connector lower end is provided with bulge-structure, end cover nut lower end is provided with internal screw thread, the external screw thread to match with end cover nut is provided with outside incision of trachea casing joint, external connector is connected with incision of trachea casing joint by end cover nut, tracheostomy cannula is placed on to the pipe of patient first when use, the external connector of closed sputum aspirator is connect with incision of trachea casing joint, it is tightened by the end cover nut on closed sputum aspirator with incision of trachea casing joint, the bulge-structure of external connector lower end setting plays position-limiting action to end cover nut, using this connection type, both external connector and incision of trachea casing joint stable connection can have been guaranteed, It does not fall off, and the inscribed connector on closed sputum aspirator may be implemented to realize rotation relative to incision of trachea casing joint.
Description
Technical field
The utility model relates to the field of medical instrument technology, in particular to a kind of tracheostomy cannula and closed sputum aspirator
Connection structure.
Background technique
Cervical trachea cuts in tracheotomy system, is put into metal or silica gel sleeve pipe, to release laryngeal dyspnea, breathing
Dyspneic a kind of common surgical caused by dysfunction or lower respiratory tract ischesis.Clinically, by closed endotracheal suction
Tracheostomy cannula is connected by pipe with breathing circuit, mechanical ventilation is carried out, to guarantee the airtightness of venting process.Using close
Enclosed sputum aspirator tube carries out endotracheal suction (ets) can maintain normal mechanical ventilation during suction sputum, and when suction sputum does not need off line,
The oxygen for not interrupting patient supplies, and can effectively maintain blood oxygen saturation, the Relapse rate caused by preventing because of anoxic decreases disengagement
Ventilator gives patient's bring fear；Simultaneously can prevent secretion splash, improve air of the sickroom environment, protection medical worker,
It guards against cross infection.Therefore, tracheae cuts the daily nursing of tracheal tube, closed sputum aspirator and breathing pipeline etc. after tracheotomy
It works particularly important.
External connector on existing tracheostomy cannula connector and closed sputum aspirator passes through plug connection, inserting mode
Structure is simple, and the relative rotation of external connector can be realized in the case where tracheostomy cannula is fixed, facilitates external connect
Head is connect with external breathing circuit.But since the change of patient body position or violent cough reflex etc. are dynamic during clinical care
Make, the external connector grafting on tracheostomy cannula connector and closed sputum aspirator is easy to appear obscission.On the one hand, it falls off
Closed sputum aspirator external connector touch patient skin or mouth nasal secretion etc., increase patient infection risk；Separately
On the one hand, it not can guarantee the airtightness in venting process, influence patient's row respirator treatment, seriously jeopardize the life peace of patient
Entirely.
Summary of the invention
Purpose of the utility model is to solve the deficiency in background technique, it is simple to provide a kind of structure, easy to use,
It is safe and efficient and tracheostomy cannula connector and closed sputum aspirator stable connection may be implemented, will not fall off and may be implemented interior
The device that connector is relatively rotated relative to incision of trachea casing.
A kind of tracheostomy cannula and closed endotracheal suction pipe connecting structure, including external connector, end cover nut and tracheae are cut
Casing joint is opened, external connector lower end is provided with bulge-structure, and end cover nut lower end is provided with internal screw thread, and incision of trachea casing connects
Head outside is provided with the external screw thread to match with end cover nut, external connector and incision of trachea casing joint and passes through end cover nut company
It connects.
The working principle and use process of the utility model:
In use, tracheostomy cannula to be placed on to the pipe of patient first, external by closed sputum aspirator is connect
Head is connect with incision of trachea casing joint, is screwed admittedly by the end cover nut on closed sputum aspirator with incision of trachea casing joint
Fixed, the bulge-structure of external connector lower end setting plays position-limiting action to end cover nut, using this connection type, can both protect
External connector and incision of trachea casing joint stable connection are demonstrate,proved, is not fallen off, and may be implemented on closed sputum aspirator inscribed connects
Head can realize relative to incision of trachea casing joint and rotate that convenient inscribed connector is connected to with breathing circuit.
The utility model has the beneficial effects that
The utility model structure is simple, easy to use, safe and efficient, and incision of trachea casing joint and external connector pass through end
Box nut links together, and is threadedly coupled and stablizes and will not fall off, and the bulge-structure of end cover nut and external connector lower part can be with
It realizes that inscribed connector is relatively rotated relative to incision of trachea casing, facilitates the close connection of inscribed connector and breathing circuit,
Normal mechanical ventilation is maintained, the probability that patient infects is reduced, reduces length of patient stay, while reducing medical staff
Working strength.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of the utility model.
Fig. 2 is the utility model part fractionation structural representation.
Fig. 3 is the end cover nut schematic diagram of the utility model.
Fig. 4 is the utility model use state diagram.
Specific embodiment
Shown in please referring to Fig.1 to Fig.4, a kind of tracheostomy cannula and closed endotracheal suction pipe connecting structure, including external connect
First 1, end cover nut 2 and incision of trachea casing joint 3,1 lower end of external connector are provided with bulge-structure 10,2 lower end of end cover nut
It is provided with internal screw thread, the external screw thread to match with end cover nut 2,1 He of external connector are provided with outside incision of trachea casing joint 3
Incision of trachea casing joint 3 is connected by end cover nut 2.
The working principle and use process of the present embodiment:
Shown in please referring to Fig.1 to Fig.4, in use, tracheostomy cannula 4 is placed on to the pipe of patient first, it will
The external connector 1 of closed sputum aspirator 5 is connect with incision of trachea casing joint 3, passes through the end cover nut on closed sputum aspirator 5
2 are tightened with incision of trachea casing joint 3, and the bulge-structure 10 of 1 lower end of external connector setting plays limit to end cover nut 2
Effect, using this connection type, can both guarantee external connector 1 and 3 stable connection of incision of trachea casing joint, not fall off,
The inscribed connector 6 on closed sputum aspirator 5 may be implemented again can realize rotation relative to incision of trachea casing joint 3, convenient
Inscribed connector 6 is connected to with breathing circuit.
