Adjustable first-aid airway opener

Technical Field

The application relates to the technical field of airway openers, in particular to an adjustable emergency airway openers.

Background

Open airway is an important step in the process of cardiopulmonary resuscitation when a patient breathes and cardiac arrest; is also an essential step in the pre-oxygenation process prior to intubation of all patients requiring an endotracheal tube. The airway can be opened in two ways in general clinical practice: a head-raising chin-lifting method and a two-hand jaw-supporting method. The specific method for opening the airway by the head-raising chin-lifting method is as follows: the operator puts one hand on the forehead of the patient to press forcefully, so that the head of the patient is leaned back, and the food and middle fingers of the other hand lift up the chin, so that the connecting line of the mandibular point and the earlobe of the patient is vertical to the ground, and the air passage is unobstructed. The specific method for opening the airway by the two-hand jaw supporting method is as follows: the two cheekbones of the patient are pressed by the thumbs of both hands, and the angle of the lower jaw is lifted upwards by the middle finger and the ring finger to open the airway. The two-hand jaw supporting method is more definite in opening the airway, and is also suitable for patients with cervical vertebra injuries, who cannot use the head-raising chin lifting method, but is more labor-consuming.

Currently, the prior patent publication number is: the Chinese patent of CN113926036A discloses a jaw-supporting first-aid airway opener, which solves the problems that the existing artificial lifting of a mandible open airway is easy to increase the fatigue degree of personnel for a long time, and comprises an adjusting cross rod, wherein both ends of the adjusting cross rod are rotationally connected with supporting rods, the lower ends of the supporting rods are connected with contact pieces, one ends of the contact pieces are connected with connecting rods, one ends of the connecting rods are rotationally connected with adjusting pull rods, one ends of the adjusting pull rods are rotationally connected with a support, and compared with the traditional artificial jaw-supporting open airway, the device can be clamped at the cheekbones and the mandible, so that the mandible can lift the open airway, the duration is long, the fatigue degree of the artificial jaw-supporting first-aid airway is effectively avoided, and meanwhile, the device is convenient to use; according to the application, through the arrangement of the adjusting cross rod, the first rod body and the second rod body can move in opposite directions, so that the transverse width of the device is adjusted to adapt to patients with different facial forms.

The prior patent publication number is: chinese patent CN112155897AA discloses a medical airway opening device for opening an airway, comprising a base plate, a support pad, a mandibular support device capable of automatically adjusting the height of the mandible of a patient with an open airway as required, a width adjustment device, and a controller; the width adjusting device is wrapped in the support pad; the controller is respectively connected with the mandible supporting device and the width adjusting device in a communication way. Can carry out effectual support to the lower jaw of the patient who needs to carry out open air flue, avoid medical personnel to lift up patient's lower jaw with the hand, reduce medical personnel's intensity of labour, bring great facility for medical personnel's work of opening air flue.

However, in the implementation process of the technical scheme, at least the following technical problems are found:

the structure is complicated, and the operation is complicated: when the conventional emergency airway opener is used, the structure required to be adjusted is various, the head of a patient is required to be continuously adjusted during operation, and the head of the patient cannot be supported, but the emergency airway opener is most important to be convenient to apply, is used for rescuing people such as fire fighting, spends excessive time on an adjusting device, seriously affects timely rescuing of the patient, is excessively large in size and inconvenient to retract, is limited in size for emergency treatment, is convenient to move quickly, is limited in size, can only often carry one medical kit, occupies excessive unnecessary space for the device which is complicated in retraction or excessively large in size, and can also affect convenience in retraction and use.

Example 3

Based on embodiment 1 or 2, the embodiment of the application effectively solves the technical problem of adjusting difficulty when the existing first-aid airway opener is used, and the general thought is as follows:

two corresponding extrusion barrels 54 are installed in the sliding block 52, and the two extrusion barrels 54 are respectively arranged on the upper side and the lower side of the extension rod 51, as shown in fig. 8 and 9;

wherein, the inside of the extrusion barrel 54 is provided with a clamping strip, and when the extrusion barrel 54 is attached to the outer wall of the extension rod 51, the clamping strip is correspondingly clamped with a clamping groove on the outer wall of the extension rod 51, and at this time, the friction force between the extension rod 51 and the extrusion barrel 54 is increased, so that the sliding block 52 cannot slide on the extension rod 51.

In some examples, the two sides of the sliding block 52 are respectively connected with a side plate 53, and a rotating shaft between the side plate 53 and the sliding block 52 is hinged with the end parts of the side rods 4, as shown in fig. 6 and 10, so that the sliding block 52 is interlocked with one end of the side rod 4;

the outer wall of the side plate 53 is inserted with a pressing pin 56 (two sides of the installation are provided with elongated through holes, and the pressing pin 56 extends out of the through holes, as shown in fig. 1, not only the pressing pin 56 is convenient for a user to press, but also the sliding position of the sliding block 52 can be limited, and one end of the pressing pin 56 passes through a rotating shaft between the side plate 53 and the sliding block 52 and extends between the two pressing cylinders 54;

when the extruding pin 56 extrudes toward the extruding cylinder 54, the two extruding cylinders 54 are separated from each other, as shown in fig. 8 and 9, at this time, the clamping strip on the inner wall of the extruding cylinder 54 cannot be clamped with the clamping groove on the outer side of the extension rod 51, so that the sliding block 52 can slide along the outer wall of the extension rod 51, thereby adjusting the position of the sliding block 52, and finally, the side rod 4 connected with the sliding block 52 drives the supporting rod 2 to incline, thereby adjusting the height of the neck pillow 3.
