Description

Simple handheld laryngoscope

Technical Field

The utility model belongs to the field of medical equipment, especially, relate to a simple and easy hand-held type laryngoscope.

Background

Because the position of the larynx is deep, the examining structure is complex, the larynx can not be directly observed, and the laryngeal examination needs to be carried out by means of a laryngoscope. The existing laryngoscope consists of a laryngoscope lens, a laryngoscope handle and a light source, wherein the laryngoscope lens comprises a tongue depressor, a flange and a top end. The tongue depressor is a part for lifting soft tissues at the bottom of each mouth of a tongue body upwards and exposing an epiglottis and a larynx to the maximum degree, the shape of the tongue depressor is generally three types of straight type, bent type and straight and bent type, small bulbs for lighting are arranged at the front end of the tongue depressor, and many people use bent types at present. The flange is a part protruding downwards from the left edge of the tongue pressing plate and has the function of keeping the oral cavity open and pushing the tongue body towards the left side of the oral cavity, so that the sight is further unobstructed. The tip acts as the top of the tongue depressor, which acts to pull the epiglottis to reveal the glottis.

In clinical practice, first aid of newborn infants is often performed, so laryngoscope intubation is often used. In practice, however, it has been found that the flange of the laryngoscope blade has little effect and is conversely more of a side effect, since the intubating technician does not need to expose much, even if he can intubate with his or her free hand. Because the oral cavity of a newborn is small, and the existing laryngoscope is large, the gum is occasionally damaged when the laryngoscope is used for intubation, the main reason is that the too wide flange easily causes gum bleeding, even the intubation fails, and the rescue is delayed.

SUMMERY OF THE UTILITY MODEL

To the problem that prior art exists, the utility model provides a simple and easy hand-held type laryngoscope.

The utility model discloses a basic scheme: a simple handheld laryngoscope comprises a handle, wherein the handle is connected with a laryngoscope lens, the laryngoscope lens comprises a tongue depressor and a top end, one end of the tongue depressor is connected to the handle, the other end of the tongue depressor is connected with the top end, a light source and a light source transmission tube are embedded in the tongue depressor, a lamp cap of the light source raises from the back of the embedded part, and a light source switch is arranged on the handle.

Compared with the prior art, this basic scheme's beneficial effect: this laryngoscope has removed the flange on the traditional laryngoscope piece, all embeds light source and light source transmission pipe in the tongue depressor, and the lamp holder of light source is favorable to illuminating the throat from embedding back new line, the utility model discloses with realize embedding integral type lens for the compact structure of laryngoscope piece, easy operation is simple and easy, and the intubate is swift and the success rate is high, is difficult to appear damaging, has greatly protected the neonate, and the disinfection is simple and convenient.

Furthermore, the tongue depressor is of a bent structure, the top end of the tongue depressor is smoothly bent, and the tongue depressor and the top end of the tongue depressor are integrally formed.

The bent structure is beneficial to ensuring the smooth operation of the intubation. The top end is smoothly bent to avoid sharp points, and the damage is reduced.

Further, the tip is bent downward 15 degrees.

The tongue depressor is prevented from entering the mouth of the newborn infant to damage the palate, and the protective effect is achieved.

Further, the length of the tongue depressor is 20-30 mm, and the thickness and the width of the part section of the tongue depressor connected with the top end are 2-3 mm and 6-8 mm respectively.

The volume of the spatula is such as to accommodate the intubation of a newborn infant.

Further, the diameter of the light source transmission tube is 3mm, and the light source is arranged at the part, connected with the top end, of the tongue depressor.

The light source transmission tube is set to be thin so that the embedding surface is as smooth as possible.

Further, the outer surface of the handle is provided with a friction sleeve.

The friction layer plays a role of skid resistance.

Further, the handle is of a hollow structure and comprises a resin inner layer and a stainless steel outer layer, and the resin inner layer is completely coated by the stainless steel outer layer; the laryngoscope lens is made of stainless steel materials.

The handle reduces its weight as much as possible for the operator is lighter when holding the handle.

Furthermore, the handle and the tongue depressor are detachably connected.

The tongue depressor can be taken down from the handle, thereby being convenient for replacing and disinfecting the tongue depressor.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The application principle of the present invention will be further described with reference to the accompanying drawings and specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a handle 1, a laryngoscope lens 2, a friction sleeve 3, a light source switch 4, a connector 5, a threaded hole 6, a tongue depressor 7, a light source transmission tube 8, a light source 9, a top end 10, a connecting sheet 11, a notch 12 and a bolt 13.

The embodiment is based on the following figures 1 and 2: the utility model provides a simple and easy hand-held type laryngoscope, includes handle 1, and handle 1 establishes to hollow structure, and handle 1 includes that resin inlayer and stainless steel are outer, and the stainless steel skin wraps up the resin inlayer completely to reach the weight that reduces handle 1, make the operator lighter when holding handle 1.
