Abstract

The utility model relates to a slippage preventing device of a tracheal catheter. The slippage preventing device comprises the tracheal catheter, an oral pad, an upper dental base, a lower dental base, an upper elastic component, a lower elastic component and an elastic locating ring. The tracheal catheter is sleeved in a center hole of the oral pad at intervals. The upper dental base and the lower dental base are respectively fixedly arranged on the upper side and the lower side of the oral pad through the upper elastic component and the lower elastic component. The tracheal catheter which is inserted between an oral cavity side and the oral pad is provided with the elastic locating ring which is tightly matched with the tracheal catheter, and so that the tracheal catheter can be prevented from being slipped from the center hole of the oral pad. The slippage preventing device of the tracheal catheter is not afraid of soaking of oral secretions, and fixation and fastness are achieved.

Description

A kind of endotracheal tube anti-slip device

Technical field

This utility model relates to a kind of endotracheal tube and patient head fixedly secures device.

Background technology

When cervical vertebra, lumbar vertebra, cranium brain posterior approach and burn need back bark fetching skin grafting, all need the patient ventricumbent position, carry out with endotracheal tube that muscle relaxant anesthesia is lower could perform the operation, patient's face down, endotracheal tube, mouth pad and are in vacant state.Existing way is to be fixed on patient's face with adhesive plaster or operation mucosa.Because the outflow of patient's mouth juice can be soaked adhesive plaster or operation mucosa, endotracheal tube easily occurs take off pipe or pendant pipe phenomenon, cause patient's brain deficiency, even death due to anoxia.

Summary of the invention

In order to overcome the shortcoming of prior art, this utility model provides a kind of endotracheal tube anti-slip device, and it is not afraid of the oral cavity separatory and soaks, fixation.

The technical scheme in the invention for solving the technical problem is: it comprises endotracheal tube, mouthful pad, upper and lower dens supporter, upper and lower elastic parts and elasticity centring ring, described endotracheal tube is enclosed within mouthful centre bore of pad with gap, the both sides up and down of mouth pad are respectively by the fixing upper and lower dens supporter of upper and lower elastic parts, have and the friction tight elasticity centring ring of endotracheal tube on the endotracheal tube between endotracheal tube insertion buccal side and mouthful pad, can prevent endotracheal tube slippage from the centre bore of mouth pad.

This utility model is not afraid of the oral cavity separatory and is soaked, fixation; Simple in structure, cost is low.

Description of drawings

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Fig. 1 is this utility model front view;

Fig. 2 is the A-A cutaway view in this utility model Fig. 1.

The specific embodiment

As shown in Figure 1, 2, it comprises endotracheal tube 2, mouthful pad 4, upper and

lower dens supporter

5,8, upper and lower elastic parts 6,7 and elasticity centring ring 3, described endotracheal tube 2 is enclosed within mouthful centre bore of pad 4 with gap, the both sides up and down of mouth pad 4 are respectively by upper and lower elastic parts 6,7 fixing upper and

lower dens supporter

5,8, have and the friction tight elasticity centring ring 3 of endotracheal tube 2 on the endotracheal tube 2 between endotracheal tube 2 insertion buccal side and mouthful pad 4, can prevent endotracheal tube slippage from the centre bore of mouth pad.

Described upper and lower elastic parts 6,7 is spring assembly.

During use, endotracheal tube 2 is inserted patient's mouth, allow patient's upper lower teeth be embedded in respectively in upper and lower dens supporter 5,8.Due to upper and lower elastic parts 6,7 effect, no matter patient's upper lower teeth is opened or closed, upper and

lower dens supporter

5,8 can contact with patient's upper lower teeth all the time, has guaranteed that a mouthful pad 4 can not come off from patient's oral cavity.

Claims

1. endotracheal tube anti-slip device, it is characterized in that: it comprises endotracheal tube (2), mouth pad (4), on, lower dens supporter (5, 8), on, lower elastic parts (6, 7) and elasticity centring ring (3), described endotracheal tube (2) is enclosed within mouthful centre bore of pad (4) with gap, the both sides up and down of mouth pad (4) are respectively by upper, lower elastic parts (6, 7) fix, lower dens supporter (5, 8), have and the friction tight elasticity centring ring of endotracheal tube (2) (3) on the endotracheal tube (2) between endotracheal tube (2) insertion buccal side and mouthful pad (4), can prevent endotracheal tube slippage from the centre bore of mouth pad.

2. endotracheal tube anti-slip device according to claim 1, it is characterized in that: described upper and lower elastic parts (6,7) is spring assembly.
