Description

A wainscot bracket set dress for trachea cannula bite-block is fixed

Technical Field

The utility model relates to the field of medical equipment, particularly, relate to a wainscot bracket suit that is used for trachea cannula bite-block to fix.

Background

Tracheal intubation is one of the most closely-contacted clinical operations with the airway of a patient, and is easy to cause secretion splash, spray, aerosol diffusion and the like, so that an anesthesiologist performing the operation is easy to be infected. And carry out trachea cannula fast and insert and fix, reduce and press close to the time of patient's oral area, can most effectively reduce medical personnel's risk of infecting the virus.

At present, in the treatment of severe patients and clinical anesthesia, the oral insertion of a tracheal tube is the most effective establishment mode of the artificial airway. For example, in the case of the clinical cardiopulmonary resuscitation known in China, one of the most common rescue measures is to insert an endotracheal tube into the trachea of a patient through the mouth and connect the other end to a ventilator to assist in ventilation of the patient. The trachea cannula is a technology for placing a special endotracheal tube into a trachea through a glottis, and the technology can provide optimal conditions for smooth air passage, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like. The emergency trachea cannula technology becomes an important measure in the process of cardio-pulmonary resuscitation and emergency treatment of critically ill patients accompanied with respiratory dysfunction. The trachea intubation is an important rescue technique commonly used in emergency treatment work, is one of the most widely, effectively and quickly applied means in respiratory tract management, is the basic skill which must be mastered by medical staff, and plays a vital role in rescuing the life of a patient and reducing the fatality rate.

At present medical institution is to the trachea cannula of each model, and the conventionality adopts and inserts the back that finishes at trachea cannula, parallels trachea cannula through the bite-block, then pastes trachea cannula and bite-block through the sticky tape and binds in order to do fixedly, and the bite-block mainly used prevents that patient's tooth from nibbling and stinging trachea cannula and leading to breaking or the shriveling of concave blocking. However, this fixing method has the following disadvantages:

1. the adhesive tape is stuck and fixed, the operation process is complicated, a large amount of time is consumed, and the efficiency is low.

2. Adopt the sticky tape to bind, congenital instability on the fixed mode, trachea cannula has the risk of slippage, and all need repeatedly carry out the fixed operation of adhesive tape after the intubate finishes at every turn, and the fixed technique of different medical personnel is different, leads to the fixed firm degree difference of trachea cannula.

3. For patients with more oral secretion and jaw and facial trauma bleeding, especially patients with sweating in prone position operation, the stickiness of the fixing adhesive tape is reduced after the fixing adhesive tape is moistened due to skin moisture, so that the position of the tracheal cannula is easy to change, even the tracheal cannula is detached, and the clinical risk is high.

The effect is stable, can not take place crooked, can stably guarantee that bite-block 1 is in vertical state. Simple structure, low cost, large market demand and suitability for batch production.

2. Bite-block 1 and trachea cannula fixation clamp 2 cooperation play the effect of fixed trachea cannula 7, and veneer bracket 3 plays the effect of fixed bite-block 1, has changed fixed mode in the past, simultaneously, 3 elastic deformation of veneer bracket, with the laminating of face, cooperate the head stay cord simultaneously to the face is even impetus, has guaranteed that this suit can not the slippage in normal work.

3. This suit trachea cannula round slot 6 part of stepping down is provided with stile structure 21, and the arch that has certain thickness that sets up at trachea cannula round slot 6 and bite-block via hole 5 of stepping down all plays the effect of strengthening this partial structure intensity simultaneously, has improved the current situation that this partial structure is more weak before, has increased this partial strength, makes this suit durable more. In addition, the matching of the structure of the clamping hook 22 and the clamping groove 23 ensures that the arc side of the trachea cannula 7 abdicating groove is not stressed on one side any more, so that the trachea cannula 7 abdicating groove is stressed on two sides, the structural strength of the part is further increased, and the current situation that the structural strength of the part is weaker is improved.

4. The clamping structure of the trachea cannula 7 is that an arc clamping arc plate 9 is matched with an elastic deformation arc edge 11, the elastic deformation arc edge 11 is responsible for elastic opening and closing, and the arc clamping arc plate 9 is responsible for clamping and fixing the outer wall of the trachea cannula 7. The elastic deformation arc edge 11 of the small-radius arc which protrudes to the outside is independently adopted, and the elastic deformation arc edge is used for preventing the inner wall from being torn due to the fact that the inner side material shortage stretching occurs in the process of stretching deformation, so that the arc clamping arc plate 9 is effectively protected, and the stability of stretching and folding is guaranteed. The anti-skidding stripe 10 cross-section semicircle or the triangle point profile of arc clamping arc board 9 inside wall can effectually prevent that trachea cannula 7 is not hard up from top to bottom, has guaranteed to the at utmost that trachea cannula 7 is in and presss from both sides tight fixed state, has guaranteed the security.

5. Ratchet I14 and ratchet II 15 can insert each other when the opening part is drawn in to make the one-way chucking of ratchet, thereby make ratchet I14 and ratchet II 15 can only one-way inside insert, reverse lock is dead, has guaranteed that clamping structure can only lock can not loosen and take off trachea cannula 7, thereby make two pressing plates press in opposite directions and can accomplish the tight locking of clamp of trachea cannula 7, and can only one-way locking can not reverse pine take off. Meanwhile, the length of the ratchet buckling of the ratchet I14 and the ratchet II 15 can be adjusted according to the diameter of the tracheal cannula 7, the tracheal cannula can adapt to thick and thin tracheal cannulas 7, and the application range is wide. Meanwhile, the trachea cannula 7 is inserted and fixed in a lateral mode, so that the condition that the trachea cannula 7 is shielded in the process of inserting the trachea cannula 7 can be avoided.

6. The tapered wedge 25 that the vertical outer wall of bite-block 1 set up cooperates tapered wedge screens hole 26 of trachea cannula fixation clamp 2, can make its both cup joint and can accomplish the locking fixed, reaches fast assembly's purpose, can effectually avoid crooked simultaneously.

7. The lower part of the veneering bracket 3 is stuck with a soft cushion 27, so that the comfort of the suit can be ensured, and a patient can have good experience in the using process.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
