Description

Jaw fixation device for non-invasive ventilator

technical field

The invention relates to a jaw fixation device for a non-invasive ventilator.

Background technique

Clinically, oxygen inhalation is used to correct hypoxia, increase arterial blood oxygen partial pressure and oxygen saturation, and promote metabolism. It is one of the important methods for auxiliary treatment of various diseases. There are various ways for patients to inhale oxygen, mainly including nasal catheter method, nasal congestion method, mask method, oxygen pillow method and head mask method. The hood method is suitable for infants and young children. When in use, the hood should be placed on the head of the child or the whole body of the child should be covered and oxygen should be injected for treatment. However, the hoods made of plexiglass or transparent plastic used by newborns are bulky and need to take up a lot of space when used. When infants need to inhale oxygen and the operating environment is limited, the hood method cannot be used to inhale oxygen. In order to solve the above problems, nasal catheter method or nasal congestion method is usually used clinically instead of the hood method for oxygen inhalation. During the specific operation, due to the poor comfort, children generally open their mouths, and the airtightness is not enough, and the oxygen inhalation effect is not good. In order to prevent the newborn from opening its mouth when inhaling oxygen, the medical staff had to use another bandage to bind and fix the child's jaw to ensure the therapeutic effect. However, one of the new problems caused by this is that the bony gap formed by the loose joint of the skull on the top of the infant's head and the joint of the bony suture between the occipital bone and the two parietal bones at the back of the brain, because there is no bone block, is slightly sunken compared with other parts ,soft. When using a bandage to fix the child's jaw, if the force is too large, it will easily cause injury to the child, and if the force is too small, the child's jaw cannot be fixed; the second problem is that if the bandage slips during the oxygen inhalation treatment, due to The material of the bandage is relatively soft, and it will be wrapped around the neck of the child, causing suffocation in severe cases. The third problem is that the temporary use of bandages to fix the jaw of the child requires different manufacturing methods and complicated operations.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

Please refer to Figures 1-4, the present invention provides a technical solution: a jaw fixation device for a non-invasive ventilator, including a circular head ring 1, a tightening belt 2 connected to the left side of the head ring 1, and a tightening belt 2 a support cover 3 for supporting the lower jaw that is slidably connected and a steering mechanism 4 arranged on the right side of the head ring 1; the left side of the head ring 1 is provided with a sealing port 11 communicating with the tightening belt 2; the head ring The back side of 1 is provided with Velcro 12; the outer top of the tightening belt 2 is provided with fluffy fabric corresponding to Velcro 12. The tightening belt 2 is an air bag that is evacuated in a natural state. In a natural state, the tightening belt 2 is separated from the steering mechanism 4. When in use, the tightening belt 2 passes through the fluffy fabric on the outside of the steering mechanism 4 and turns to the inside, and is connected with the steering mechanism 4. 12 magic stickers are pasted and fixed. Put the headband 1 on the child's head, slide the support cover 3 so that it can fit the child's chin, pass the tightening belt 2 around the child's face, pass through the steering mechanism 4, and tighten the outer part of the belt 2 The fluffy fabric turns to the inside, and the fluffy fabric is fitted on the Velcro 12 and fixed. Inflate the tightening belt 2 through the sealing port 11 to complete the immobilization of the infant's lower jaw. When in use, the tightening belt 2 is fixed on the head ring through Velcro 12, which is easy to operate; the tightening belt 2 does not directly contact the head of the child to prevent damage to the child; the tightening belt 2 hardens after inflating to prevent tightening The belt 2 is wrapped around the neck of the child, causing suffocation of the child; at the same time, the belt 2 is tightened and inflated to form a buffer space on the contact surface with the child's skin to improve comfort.

As a further improvement to the above technical solution, the tightening belt 2 includes a non-elastic flexible fabric 21 on the inside and an elastic fabric 22 on the outside; an airbag cavity is formed between the flexible fabric 21 and the elastic fabric 22 . The elastic fabric 22 expands outward when inflated, stiffening the cinch strap. Prevent the tightening belt 2 from expanding inwardly when inflated, squeezing the head of the child and causing injury to the child.

As a further improvement to the above technical solution, the headband 1 also includes an elastic band 16 arranged on the front for fixing the breathing tube, a storage groove 14 for accommodating the steering mechanism 4, and an elastic buckle 13; the elastic buckle The buckle 13 is sunk in the receiving groove 14 as a whole; the steering mechanism 4 includes a steering column 41 and a Y-shaped support frame 42 rotatably connected with the steering column 41; the axial angle between the steering column 41 and the head ring 1 is 40° -70°; the support frame 42 is rotationally connected with the head ring 1 through a torsion spring; the steering column 41 is separated from the head ring 1 in a natural state, and when in use, the steering mechanism 4 is sunk in the storage groove 14 as a whole, and the The support frame 42 is fixed by the elastic buckle 13 . In the initial state, the steering column 41 is separated from the head ring 1, the tightening belt 2 passes through the steering column 41, and the steering mechanism 4 is pressed by hand to make it fall into the storage groove 14 as a whole, and the elastic buckle 13 fixes the support frame 42, and the magic Paste 12 to fix the tightening band 2, and then inflate the tightening band 2 to complete the fixation of the infant's jaw, and the breathing tube is fixed through the elastic band 16 to prevent the breathing tube from swinging left and right. After the oxygen inhalation is finished, the gas in the tightening belt 2 is released through the sealing port 11, and then the elastic buckle 13 is pressed by hand, and the elastic buckle 13 is separated from the support frame 42. The ring 1 is separated, and finally the tightening belt 2 is pulled out from the steering column 41, and the head ring 1 is removed. In addition to adopting the above structure, the steering mechanism 4 of the present invention can also adopt a triangular plate to turn to an overturned structure.

As a further improvement to the above technical solution, the inside of the headband 1 is pasted with a sponge lining. Prevent the headband 1 from being too tight and causing injury to the child.

As a further improvement to the above technical solution, the support cover 3 includes a support plate 31 , an air spring 32 disposed on the support plate 31 , and a sponge pad 33 disposed on the air spring 32 . During use, the sponge liner 33 is in contact with the child's jaw to improve the comfort of the child. The air spring 32 creates a buffer space between the child's jaw and the support cover 3, preventing the support cover 3 from being too tight to cause injury to the child.

As a further improvement to the above technical solution, the support cover 3 further includes a pressure sensor 34 disposed on the air spring 32 ; an indicator light 15 electrically connected to the pressure sensor 34 is disposed on the elastic band 16 . Air spring 32 receives extrusion during use, and indicator light 15 is opened, and after support cover 3 separates with infant's jaw, air spring 32 returns to initial state, and indicator light goes out. It is convenient for doctors to check whether the support cover 3 is separated from infants and young children, so as to ensure the airtightness of oxygen inhalation and improve the therapeutic effect of oxygen inhalation.
