Abstract

A disposable tracheotomy cannula with a side hole comprises an outer cannula, wherein the side hole is formed in the cannula body of the outer cannula; an inner cannula is a hollow catheter of which the two ends are open and the external diameter is equal to the internal diameter of the outer cannula; a cannula core is an arc-shaped solid catheter of which one end is provided with a bulgy head; the bulgy head is matched with one open end of the inner cannula; and a plug is matched with one open end of the outer cannula. Preferably, two inner cannulas are provided. As the disposable tracheotomy cannula with the side hole adopts such a mode that the outer cannula, the inner cannula, the cannula core and the plug cooperate with one another, once a patient is separated from a breathing machine, the inner cannula can be drawn out while the outer cannula with the side hole is left, and the patient can autonomously cough and discharge sputum so as to avoid stimulation to a trachea caused by artificial sputum suction; direct cannula drawing can be performed without replacement of a metal cannula while standard cannula drawing is achieved; meanwhile, the inner cannula can be replaced to be disinfected or subjected to sputum scab cleaning, which can overcome the defects of the conventional trachea cannula; and the structure is simple and the use is convenient.

Description

Disposable band side opening tracheostomy cannula

Technical field

This utility model relates to a kind of medical supplies, especially a kind of disposable band side opening tracheostomy cannula that is specifically designed to tracheotomy.

Background technology

The tracheal casing pipe of using clinically is generally the common tracheostomy cannula of band air bag at present, and there is following shortcoming in this sleeve pipe:

One, behind patient's separating respiratory machine, often need carry out plugging before the tube drawing and test to observe it and whether possess complete autonomous cough expectoration ability, and the too narrow observation that has hindered the autonomous expectoration ability of patient in gap between tube wall and the trachea after the common tracheostomy cannula plugging;

Two, the patient is after being with pipe for a long time, and tube drawing goes to toward needing to change a metal canula as transition, not only bothers, and has also increased patient's misery and medical expense;

Three, the patient of band pipe possesses the expectoration ability sometimes, and because the existence of tracheal casing pipe has stoped the eliminating of sputum, need increase the chance of air flue damage by artificial suction expectorant this moment;

Four, the patient is with the easy accompanying infection of pipe or expectorant crust to stop up conduit for a long time.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of disposable band side opening tracheostomy cannula, can overcome the shortcoming of existing tracheal casing pipe, can allow the patient to be with the pipe expectoration, the side opening of tube wall has increased the unobstructed property of air flue, and need not to change directly tube drawing of metal canula, simple in structure, easy to use.

For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of disposable band side opening tracheostomy cannula, comprise trocar sheath, and offer side opening on the pipe shaft of trocar sheath; Inner sleeve is the hollow conduit that the external diameter of both ends open equals the internal diameter of trocar sheath; Tube core is the solid conduit of arc of the swollen head of an end band, and swollen head matches with the inner sleeve opening; Plug matches with the opening of trocar sheath.

The external diameter of swollen head is not less than the internal diameter of inner sleeve opening.

Plug is preferably filled circles column pipe.

The external diameter of plug equals the internal diameter of the opening of trocar sheath.

Trocar sheath is preferably the tracheostomy cannula of band air bag.

The quantity of inner sleeve is preferably two.

A kind of disposable band side opening tracheostomy cannula that this utility model provides, because the mode that adopts trocar sheath, inner sleeve, tube core and plug to match, in case patient's separating respiratory machine, can pull out inner sleeve, the trocar sheath of leave strip side opening, the patient can exempt the artificial expectorant of inhaling to the stimulation of trachea by the side opening expectoration of independently coughing; When reaching the tube drawing standard, need not to change the direct tube drawing of metal canula, inner sleeve can be changed sterilization simultaneously or clean the expectorant crust, can overcome the shortcoming of existing tracheal casing pipe, simple in structure, easy to use; The quantity of inner sleeve is preferably two, can frequent sterilization and clean inner sleeve, reduced possibility of infection.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the structural representation of this utility model trocar sheath;

Fig. 2 is the structural representation of this utility model inner sleeve;

Fig. 3 is the structural representation of this utility model tube core;

Fig. 4 is the structural representation of this utility model plug.

The specific embodiment

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, this utility model comprises trocar sheath 1, offers side opening 3 on the pipe shaft of trocar sheath 1;

Inner sleeve 4 equals the hollow conduit of the internal diameter of trocar sheath 1 for the external diameter of both ends open, and inner sleeve 4 can closely paste mutually with the inwall of trocar sheath 1 after putting into trocar sheath 1;

Tube core 5 is the solid conduit of arc of swollen 6 on an end band, and swollen 6 is matched with inner sleeve opening 7;

Plug 8 matches with the opening 9 of trocar sheath 1.

Swollen 6 external diameter is not less than the internal diameter of inner sleeve opening 7.

Plug 8 is filled circles column pipe.

The external diameter of plug 8 equals the internal diameter of the opening 9 of trocar sheath 1.

Trocar sheath 1 is the tracheostomy cannula of band air bag 2.

The quantity of inner sleeve 4 is two.

Use of the present utility model is as follows:

During use, earlier inner sleeve 4 is inserted trocar sheath 1, tube core 5 is inserted inner sleeve 4, make swollen 6 of tube core 5 to block inner sleeve opening 7, the trocar sheath 1 that will be had tube core 5 and inner sleeve 4 by tracheotomy place inserts trachea, can connect respirator to behind the airbag aeration; Can pull out inner sleeve 4 when patient's separating respiratory machine and when possessing autonomous cough ability and with the opening 9 of plug 8 shutoff trocar sheaths 1, the patient can change the per nasal oxygen uptake into and by the side opening expectoration of independently coughing, exempt the artificial expectorant of inhaling to the stimulation of trachea; When if patient's amount of expectoration is more or expectoration is required great effort, pulls out plug 8 and can inhale expectorant through trocar sheath 1; If conditions of patients changes when needing to use respirator, be inserted in inner sleeve 4 connection respirators and get final product.
