Description

Neonate laryngoscope system

Technical Field

The invention relates to the field of laryngoscopes, in particular to a neonatal laryngoscope system.

Background

In neonatal airway care, the adoption of many first aid procedures requires the reliance on intubation assistance, where the placement of a laryngoscope is the basis for the subsequent operation to be performed for the entire intubation procedure. Laryngoscopes are divided into two categories, one straight and one curved called Macintosh, and for neonates, my hospital uses Miller more.

As the organs of the neonate were originally exposed and used and the organs of the body were weaker, the tolerance was very poor and the organs were very small compared to children and adults. The exposure of the mucosa tissue of the oral cavity is not typical, and furthermore, the mucosa tissue of the throat part may have the problems of edema, much secretion and the like due to the very small mouth of the neonate, so the experience and the manipulation are very tested when the laryngoscope is put into the neonate before intubation. Experience is often more important than theory, and many newly-attending physicians do not have as high a success rate of operation as nurses. The operation needs to be rapid, accurate and reasonable, and once the heart rate is stirred slightly and delayed or the heart rate is placed in the wrong position, the heart rate is stirred quickly, obviously drops and even the whole body is cyanosed. The insertion is performed for the second time in time, and the insertion fails for the last time, so that obvious damage is caused, more bloody secretions are generated, and good glottis can be exposed and cannot be seen clearly. The rational use and assistance of the tool is critical. The proper laryngoscope, in combination with corresponding auxiliary measures, can greatly improve the success rate of intubation.

Detailed Description

The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

The reason for the failure of the post-analysis static insertion mainly comprises the following points:

firstly, the skeletal development and the muscle development of a newborn are in starting states, the head position is not easy to fix, when the operation is carried out, the head of the newborn is kept neutral by cushioning the two sides of the head with cloth dressing, and the head of the newborn is prevented from swinging left and right when the operation is carried out on the instrument, so that the instrument can hurt the nearby organs or mucous membranes. However, the fixing effect of the gauze auxiliary material is not good, and people still need to additionally assist the head of other people or the head of an operator needs to be assisted by the operator, as shown in fig. 9, if the gauze auxiliary material is assisted by other people, a newborn baby is very small, the operation space is very narrow, as shown in fig. 10, the operation is very inconvenient, and the visual field and the space of a doctor are not good. If the doctor holds the endoscope by himself, the subsequent operations such as mask and intubation after the laryngoscope is placed are difficult to vacate.

Meanwhile, the head-up angle is also needed to be noticed in addition to preventing the neonate from swinging left and right. When the laryngoscope is inserted, the upward angle of an infant patient is very critical, a novice hand usually requires that the left hand holds the laryngoscope and the right hand holds the neck of the infant to help the infant to lean backwards, the laryngoscope is inserted deeply and then slowly retreats until the glottis is exposed and the epiglottis and the back wall of the pharynx are retreated to operate. If the glottis is not well exposed, the right-hand index finger can be used for pressing the throat to better expose the glottis; if there is more secretion, the laryngoscope is quickly scraped with a prepared cotton swab and then quickly intubated without withdrawing the laryngoscope. The above operation shows that the head angle is critical to the success rate of intubation, as illustrated in fig. 11, the good viewing angle, and the proper insertion position, are directly related to the supine angle of the neonate.

From the above analysis, it can also be seen that, in operation, the doctor needs to vacate the right hand to perform some necessary operations, and the existing device cannot fix the head of the newborn, which causes the doctor to hold and adjust the position and angle of the head manually during the whole operation process, further increasing the difficulty of the operation.

Furthermore, the observation mode of the existing laryngoscope is mainly direct naked-eye observation or observation on the display 21 by using an electronic image, obviously, the imaging of the electronic image is clearer, and the laryngoscope can also have an amplification function and is more beneficial to auxiliary operation. However, if the display screen is erected independently, the doctor raises the head to watch the infant, and the watching visual angle is separated from the operation position, so that the doctor is dangerous, the doctor cannot consider the matching situation between the periphery of the mouth and the nose of the infant and the instrument, and can only see the situation in the throat enlarged by the display screen. However, the use of electronic images has been followed by some non-negligible adverse effects, making many experienced nurses and doctors reluctant to use electronic images.

Finally, the most common problem is the laryngoscope sizing, which is a very weak throat mucosa of newborns, causing significant trauma to the neonate with each insertion and producing more bloody secretions, making subsequent procedures more difficult. Therefore, during the insertion process, the width of the laryngoscope is expected to be as small as possible, and the laryngoscope will not excessively press and damage the surrounding tissues even if unsuccessful, but is too small, so that the laryngoscope is not fully exposed to the internal conditions after entering, the manufacturing of the passage is not ideal, and the decision is very difficult.

Example 1: neonate laryngoscope system

Comprises a laryngoscope module, a display module and a limit module.
