Description

A kind of lower jaw holds up device

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically, is that a kind of lower jaw holds up device.

Background technology

Glossoptosis is clinical urgency, danger, critically ill patient causes respiratory tract obstruction and causes the main cause of dyspnea and death by suffocation, prevention that clinical treatment adopted and emergency measures generally are divided into two kinds of situations: the one, and good for ordinary circumstance, patient is just owing to the drowsiness glossoptosis that causes, be to adopt the head position that changes patient mostly, with amesiality, can alleviate the symptom of its hypopnea, but, in clinical practice, the glossoptosis of most patient all is because the state of an illness is critical or the downern consumption is excessive, patient is drowsiness or deep coma causes, in this case, the simple patient head position that changes is difficult to alleviate its dyspneic symptom, must with the hands patient's bilateral lower jaw be held up to the front upper place by special medical personnel, and the rear wall that makes root of the tongue portion break away from pharyngolaryngeal cavity could be dredged respiratory tract, this kind method is safer reliable, but must waste time and energy by special messenger's long-time operation, increased many troubles and added burden to medical personnel.In addition, can also adopt the method for placing oropharyngeal airway or circulation of qi promoting cannula, still, place oropharyngeal airway and be easy to stimulate the oral cavity to cause secretions increase, need to absorb sputum regularly, otherwise the possibility that has the sputum mistake to inhale; Though tracheal intubation can prevent above-mentioned danger, but intubate itself is exactly a kind of wound to patient, particularly the cardiovascular system to patient has very big zest and danger, and, the standing time of conduit is unsuitable long, so, the patient respiration function still can situation under, adopting the method for tracheal intubation to improve the dyspnea that glossoptosis causes not is a kind of ideal method.At present, treat clinically because of glossoptosis causes the dyspnea aspect and still do not have ideal method and apparatus.

Summary of the invention

The purpose of this utility model is to provide a kind of medical apparatus and instruments of easy to operate, time saving and energy saving, safe and reliable, alternative manually-operated treatment glossoptosis, and a kind of lower jaw holds up device.

This utility model is achieved in that a kind of lower jaw holds up device, comprise postbrachium, two forearms, two support arms, two regulating arms and Lower jaw support, forearm is made of fixed arm and lever arm, lever arm is sleeved on the fixed arm, relative position between the two can be regulated, oblique notch in the fixed arm upper end, the lower end is connected with postbrachium, support arm is inserted in the skewed slot, suit regulating arm and adjusting device in the support arm by regulating the position that adjusting device can change regulating arm, connect on the regulating arm and regulate support arm, regulate support arm one end and regulating arm and fix, an end connects Lower jaw support.

Use of the present utility model is: glossoptosis patient's head is placed on lower jaw holds up between the postbrachium and two forearms of device, by regulating the position that adjusting device changes regulating arm, make Lower jaw support hold up patient's lower jaw, thereby guarantee that patient respiration is unimpeded, so alternative manually-operated of this utility model apparatus, time saving and energy saving, safe and reliable, be not subjected to time restriction, alleviated clinical medical and nursing personnel's labor intensity greatly, simultaneously, use adjusting device to regulate, easy to operate.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described in further detail:

Fig. 1 partly cuts open figure for this utility model master looks.

Fig. 2 is that the A of Fig. 1 is to partial sectional view.

Fig. 3 is the B-B cutaway view of Fig. 1.

As shown in the figure, the forearm that holds up device is made of fixed arm 5 and lever arm 6, lives Swing arm 6 is enclosed within on the fixed arm 5, and keeping at a certain distance away on the fixed arm 5 arranges screw, Screw 12 passes lever arm 6 and is fixed in the screw, by adjustment screw 12 at screw In the position can regulate lever arm 6 with respect to the position of fixed arm 5, lever arm 6 The upper end connect contact arc sheet 11. Oblique notch in fixed arm 2 upper ends, square hole is offered in the lower end, Postbrachium 1 passes square hole and is connected with fixed arm 5, and is fixing by screw 13 between the two. Support arm 2 is inserted in the skewed slot, support arm 2 inner sleeves dress regulating arm 3, regulating shaft 8 and Spring fitting device, regulating arm 3 is spline-simulating, regulating shaft 8 is gear shaft, both Match, it is extended or retracted to drive regulating arm 3 by turning gear wheel shaft 8, bullet The spring fixture comprises spring stator 9 and stator control handle 10, the fixing dress of spring Put the rotation that to brake regulating shaft 8, connect on the medial surface of regulating arm 3 to regulate and prop up Arm 4, regulating support arm 4 is an arc-shaped steel body, an end and regulating arm 3 are fixing, and one End connects Lower jaw support 7, and Lower jaw support 7 is the triangle body shape, is made by duroplasts, connects Touch the compound softer foamed plastics of face.

Use of the present utility model is as follows: at first according to the width of patient head, adjust The spacing of two forearms, fixing with screw 13, according to the length of patient's incidence, transfer again The position of lever arm 6 is decided in solidating, makes contact arc sheet 11 be against patient's shoulder, rotates Regulating shaft 8 changes regulating arm 3 positions, and the Lower jaw support 7 of regulating support arm 4 is held The bilateral lower jaw continues rotation regulating shaft 8, and regulating arm 3 is by regulating the lower of support arm 4 Carry the bilateral lower jaw in the jaw holder 7, until patient's root of the tongue section breaks away from the pharyngolaryngeal cavity wall and unobstructed exhaling Inhale till the road, recycling spring adjusting device secured adjusted axle 8 prevents regulating arm 3 Glide. The utility model can alternately loosen one-sided regulating arm 3 by spring adjusting device, To avoid long-time carriage to cause the local soft tissue ischemic necrosis.
