Abstract

The utility model discloses a tracheotomy cannula which comprises a cannula body. A cover is arranged at the end, exposed out of the body of a patient, of the cannula body. The cover comprises an inner cover body and an outer cover body. A first vent hole is formed in the inner cover body. A second vent hole is formed in the outer cover body. The inner cover body covers the end, exposed out of the body of the patient, of the cannula body in an airtight mode, the outer cover body rotatably covers the inner cover body, the coincident area of the first vent hole and the second vent hole is adjusted by rotating the outer cover body, and therefore the ventilatory capacity of the tracheotomy cannula is adjusted. Due to the fact that the tracheotomy cannula comprises the inner cover body and the outer cover body which coincide with each other, the size of an air hole, enabling the tracheotomy cannula to be communicated with the outside, of the cover is adjusted through the rotation of the outer cover body and the relative motion of the vent hole in the inner cover body and the vent hole in the outer cover body, and therefore the ventilatory capacity of the tracheotomy cannula is changed or adjusted, and the ventilatory capacity of the patient can be gradually adjusted from large to small until the tracheotomy cannula is completely sealed.

Description

Tracheostomy cannula

Technical field

This utility model relates to a kind of tracheostomy cannula, relates in particular to the adjustable tracheostomy cannula of a kind of ventilation.

Background technology

Cervical trachea cuts in tracheotomy system, puts into tracheal intubation.Tracheotomy be for solving laryngeal dyspnea, breathe the not normal or lower respiratory tract secretions of technical ability be detained due to dyspneic a kind of common operation.

When needs of patients recovers respiratory function, need to block tracheal intubation, temper patient and utilize nasal respiration.But, to compare with nasal respiration, the ventilation of tracheal intubation is larger, so patient is difficult to utilize nasal respiration after short-term regulation plugging.

Utility model content

In order to address the above problem, this utility model is intended to propose a kind ofly can regulate ventilation and allow the tracheostomy cannula of respiratory function exercise.

Tracheostomy cannula of the present utility model, comprises sleeve body, and one end that sleeve body is exposed outside patient body is provided with lid; Described cock body comprises interior lid and outer cover; Interior lid is provided with the first passage; In outer cover, be provided with second passage corresponding with the first passage; Inner cap bromhidrosis thickly covers on the one end outside sleeve body is exposed patient body, outer cover is rotatably covered on interior lid, by rotary outer cover body, adjust the area overlapping of the first passage and the second passage, regulate thus the ventilation of described tracheostomy cannula.

Preferably, described the first passage and the second passage are all set to semicircle.

Preferably, described interior lid and outer cover are connected to sleeve body by nonrigid connector respectively and expose the one end outside patient body, to prevent that something lost from falling.

Because tracheostomy cannula of the present utility model comprises interior lid and the outer cover being superimposed with each other together, by rotary outer cover body, passage on interior lid and the passage relative motion in outer cover, thereby adjust whole lid by the size of the pore of tracheostomy cannula and extraneous UNICOM, change or adjust thus the ventilation of tracheostomy cannula, make patient progressively to adjust ventilation, descending, until seal tracheostomy cannula completely.

The specific embodiment

Below, by reference to the accompanying drawings the adjustable tracheostomy cannula of ventilation of the present utility model is elaborated.

As shown in Figure 1, the adjustable tracheostomy cannula of ventilation of the present utility model mainly comprises sleeve body 10 and lid 20.Lid 20 is arranged on the one end outside patient body that is exposed to of sleeve body 10.

Lid 20 is connected in one end of sleeve body 10 by nonrigid connector 23, to prevent lid 20 losses or to lose.Particularly, lid 20 comprises interior lid 22 and outer cover 21, and nonrigid connector 23 is connected to respectively interior lid 22 and outer cover 21.

The structure of interior lid 22, outer cover 21 as in Figure 3-5.

Interior lid 22 covers on one end of sleeve body 10, and outer cover 21 is covered on interior lid 21, and outer cover 21 can rotation relative to interior lid 22.

On interior lid 22, be formed with the first passage 25, in outer cover 21, be formed with second passage 24 corresponding with the first passage 25.The first passage 25, the second passage 24 can form semicircle, also can form other shapes.When the rotation relative with outer cover 21 of interior lid 22, the first passage 25 and the second passage 24 each other overlapping area can be adjusted as required, as shown in Fig. 6-8, thus, the size of the tracheostomy cannula of adjusting and the pore of outside UNICOM, therefore, ventilation can be adjusted as required.

Because tracheostomy cannula of the present utility model has the pore that can regulate ventilation, make patient can adjust as required voluntarily ventilation in use, progressively temper nose or oral cavity and breathe, can be because plugging be suddenly due to the inadaptable various discomforts that cause patient of body.
