Detailed Description

The invention is further described below with reference to the accompanying drawings.

In order to establish a smooth airway during clinical anesthesia or emergency rescue, the laryngeal mask 1 is widely applied, and fig. 1 is an application schematic diagram thereof. When the laryngeal mask is used, if no fixing measures are taken, the laryngeal mask is usually displaced and separated, ventilation difficulty is caused, and the life safety of a patient is threatened. Therefore, the utility model aims to provide an easy to use's laryngeal mask fixer, it is not firm to fix when avoiding the fixed laryngeal mask of clinical adoption adhesive tape, is difficult to the adjustment position, has potential safety risk scheduling problem.

Referring to fig. 2, in order to solve the above problems, the present invention provides a laryngeal mask holder, including a holder main body 3 and a fixing band 6, the holder main body 3 is provided with a fixing groove 301, the holder main body 3 is provided with an opening 302, and the opening 302 is communicated with the fixing groove 301, so that the laryngeal mask handle can enter the fixing groove 301 through the opening 302. The holder body 3 is provided with a bracket 302 on one side, and the bracket 302 is connected with a threaded rod 402 to form a thread pair. One end of the threaded rod 402 is connected with the nut 401, the other end of the threaded rod 402 is connected with the sliding block 403, and when the laryngeal mask handle is placed in the fixing groove 301, the sliding block 403 can be driven by rotating the nut 401 to fasten the laryngeal mask handle.

For facilitate the use, improve comfort level and security, the utility model discloses still provide following improvement:

first, the slider 403 is connected to the threaded rod 402 in the form of a selected revolute pair, and the laryngeal mask shaft is typically formed from a tube having an arc. After the improvement, as the sliding block 403 can rotate, an arc-shaped groove matched with the outer surface of the laryngeal mask handle can be arranged on the sliding block 403, so that the contact area is increased, the contact area of the sliding block 403 to the mask handle is larger, and the fastening is more stable.

Further, the shape of the fixing groove 301 may be matched with the outer surface of the laryngeal mask handle. The anti-slip pad 5 is arranged on the inner side of the fixing groove 301 of the fixer body 4 and the sliding block 403, when the laryngeal mask handle is fixed in the fixing groove 301, the anti-slip pad 5 is attached to the surface of the laryngeal mask handle, so that the contact area is increased, and the fixation is more stable.

On the other hand, in order to make the function of positioning and fixing the fixator on the face more compact, the fixator body 3 is made of a material with toughness and elasticity. And the fixer body 3 has an arc shape to fit the cheek of the user so that the fixer body 3 can fit the cheek surface of the user when the fixer is fastened to the face of the user by the fixing band 6. In addition, one face, attached to the face, of the fixator body 3 can be provided with a bite block 7, so that the laryngeal mask can be prevented from being displaced or damaged due to accidental occlusion.

The connected mode of fixed band 6 can adopt the mode of binding to fix at the user's neck, also can adopt the elastic band, or button, magic subsides, couple or other separable fixing device are connected, and this kind of connected mode belongs to comparatively common means in this field, so the utility model discloses do not do the perusal.

Concretely, a laryngeal mask fixator comprises a fixator body 3 which is matched with the arc of a jaw and cheek of a patient, and the fixator body 3 is made of tough and elastic materials in a molding mode. An oval laryngeal mask fixing groove 301 is formed in the middle of the main body. The front end of the fixing groove is provided with an opening 302, and the lower end is provided with a bite block 7. One side of the main body is provided with a bracket 304, a support nut 401, a threaded rod 402 and a slide block 403. The inner side surfaces of the fixed groove and the sliding block are stuck with anti-slip pads 5. The inner side surface of the main body is provided with foam. The main part both ends are equipped with fixed foraminiferous 303, connect fixedly through elastic fixation area 6.

The utility model discloses a theory of operation and working process as follows:

the laryngeal mask 1 is placed in the laryngopharynx, the laryngeal mask handle is pushed into the fixing groove 301 after the position is determined, the nut 401 is rotated forwards, the sliding block 403 is pushed through the threaded rod 402 to press the laryngeal mask handle tightly, the position of the laryngeal mask handle is fixed, and the fixing band 6 bypasses the neck of the pillow and can be adjusted in tightness.

If the position of the laryngeal mask 1 needs to be adjusted in the operation, the nut 401 is rotated backwards to relieve the pressure at the laryngeal mask handle, the laryngeal mask depth is adjusted, and the laryngeal mask 1 is fixed after the nut 401 is rotated forwards again.
