Description

{LARYNGOSCOPE FOR PREVENTING TOOTH DAMAGE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a laryngoscope for preventing tooth damage, and more particularly, to a laryngoscope in which a groove is formed at a position corresponding to a tooth to prevent a tooth injury of a patient during laryngoscope manipulation.

The laryngoscope is used for intubation, and the endotracheal intubation refers to the operation of placing a PVC tube (tracheal tube) with a certain length and inner diameter into the trachea using the laryngoscope.

The purpose of this tracheal intubation is to secure the patient's airway during anesthesia and surgery or when cardiopulmonary resuscitation is needed. Through these tracheal intubation, an intubated tube is connected to an anesthetic or a ventilator.

Since the airway is secured by manipulating the handle in the direction of elevating to the direction of the practitioner, the blade is frequently brought into contact with the upper teeth, Damage will occur. In the intubation of the trachea, the patient is often unconscious and does not show the response to tooth damage, and the practitioner is also unlikely to notice the tooth damage of the patient. Therefore, a laryngoscope is needed to prevent tooth damage.

The related art will be described as follows.

Korean Patent Publication No. 10-0873929 discloses a technique in which only the distal end portion of a blade is elevated only by manipulating the lever to solve a problem of dental damage of a patient. However, since the structure of the laryngeal shaft is complicated and the manufacturing cost is high, There are no shortcomings.

US Patent Publication No. 2005-0240081 discloses a laryngoscope equipped with a cushion on a blade to prevent tooth damage, but it is hard to say that it is possible to buffer only shocks and to completely prevent tooth damage.

One. 1st Example

First, the laryngeal diameter of the first embodiment will be described with reference to Figs. 1, 2, and 8. Fig.

First Embodiment A laryngoscope includes a blade 100 and a handle 200.

The blade 100 is inserted into the oral cavity of the patient when the airway is secured and varies in size depending on the age and sex and specifically includes the first end 110, the upper surface 120, the lower surface 130, And includes a side surface 140.

The first end portion 110 is inserted into the patient's airway to secure the airway. When the airway is secured by the insertion of the first end portion 110, a PVC-made tube is inserted into the airway. As shown in FIG. 8, when the handle 200 is tilted in the direction of the operator, the first end 110 is secured by the operation of the handle 200 mounted on the lower end of the blade 100, ) Is elevated to lift the epiglottis to secure airway. In this process, the blade 100 frequently pressurizes the patient's teeth and damages the teeth.

In particular, since pressure is applied to the maxillary teeth due to the characteristics of the laryngoscope manipulation, the lug of the first embodiment has a groove on the upper surface 120 of the blade for preventing damage to the patient's teeth. When the first end 110 is inserted into the airway, it is preferable that the groove is formed at a position corresponding to the upper teeth in order to enhance the effect of preventing tooth damage.

The grooves located on the upper surface 120 of the blade prevent the teeth 100 of the blade 100 from being damaged even when the airway is secured as shown in Fig.

First Embodiment The laryngoscope further includes a flexible portion 160 of a flexible material mounted in the groove. It is preferable that the finishing portion 160 is made of a flexible material so as to absorb the impact even when the teeth come into contact with the finishing portion 160, and in particular, it is preferably made of silicon. However, since the blade 100 itself is made of stainless steel, which is a hard material, it may cause discomfort to the patient when the teeth are in contact with each other. Therefore, it is possible to prevent tooth damage even if tooth contact of the blade 100 is performed by mounting the finishing portion 160 of flexible material in the groove. It is preferable that the end portion 160 is detachably attached to the groove because it is contaminated with saliva or the like when the airway is secured.

Since the blade 100 is also contaminated with the saliva of the patient when the airway is secured, it is preferable to disinfect the blade 100 after use. Since the finishing portion 160 provided in the groove of the blade 100 is detachably provided, the finishing portion 160 can be disinfected separately from the blade 100. Alternatively, the finishing portion 160 can be disposable And may be provided in a form of being mounted at every use without disinfection.

In addition, the laryngoscope of the first embodiment may further include a first blade 150 positioned on the lower surface 130. The first blade 150 is provided to have a predetermined width, thereby pressing the tongue when securing the airway so that accurate intubation can be performed. The size of the first blade 150 may vary according to age and gender as well as the blade 100.

In addition, the laryngeal diameter of the first embodiment may further include a light 170. Light 170 illuminates the airways into which the laryngoscope is inserted, thereby allowing the operator to perform an accurate intubation of the trachea.

2. Second Example

Next, the laryngoscope of the second embodiment will be described with reference to Figs. 3 and 4. Fig.

A groove is provided in the blade 100 as in the first embodiment to provide a tooth-damaging function. However, the groove 100 is wider on the upper surface 120 than the first embodiment. That is, as shown in FIG. 3, the groove extends to one end of the blade 100.

Second Embodiment It is further preferable that the laryngoscope further includes a flexible portion 160 of a flexible material mounted in the groove, so that tooth damage can be prevented even if the tooth contact of the blade 100 is performed.

Second Embodiment The closing part 160 of the laryngoscope may be provided integrally or fixedly to the groove of the blade 100 or may be provided separately. Accordingly, the manufacturer of the laryngoscope can manufacture an integrated or detachable laryngoscope accordingly.

3. Third Example

Next, the laryngoscope of the third embodiment will be described with reference to Figs. 5 and 6. Fig.

Third Embodiment The laryngoscope is provided with grooves on the upper surface 120 and the lower surface 130 of the blade and also has grooves on both sides 140 so that the entire surface of the blade 100 at the position corresponding to the patient's teeth, .

Third Embodiment Since the lumbar spine is provided with grooves as a whole on the position blade 100 surface corresponding to the patient's teeth even when the handle 200 is manipulated up and down and left and right, it is possible to prevent tooth damage more effectively.

Third Embodiment It is preferable that the laryngoscope further includes a flexible material finish portion 160 detachably mounted on the groove. However, unlike the laryngoscope of the first and second embodiments, the end portion of the laryngoscope 160 Is provided to surround the entire blade 100. 5) Due to the characteristic shape of the lid of the laryngoscope according to the third embodiment, it is preferable that the closure 160 is provided with a detachable groove 161 so that it can be easily detached. Referring to FIG. 5, the detachable groove 161 may be in the form of a straight groove, but not limited thereto, and may have a puzzle shape, a zigzag shape, and a zipper shape.
