Description

Technical Field

[0001] The utility model relates to the technical field of laryngoscope blades, in particular to a disposable laryngoscope blade for children. Background Art

[0002] Currently, video laryngoscopes are mostly used for tracheal intubation in bed. Using a disposable laryngoscope blade on the electronic main body can reduce cross-infection between patients and save disinfection costs. The operation of the video laryngoscope blade is the same as that of the traditional laryngoscope. The laryngoscope is inserted into the throat, and then the throat structure can be clearly displayed through the display screen. The glottis is clearly exposed and the accuracy is high. Therefore, the use of video laryngoscopes to complete tracheal intubation operations has been widely used in major hospitals.

[0003] However, when comparing the existing disposable laryngoscope blades for children with those for adults, although the size of the disposable laryngoscope blades for children is smaller than that of the laryngoscope blades for adults, it is difficult for children to cooperate well, and the size of the children's laryngoscope blades is fixed, and children are prone to strong rejection reactions, which in turn affects the doctor's observation. Therefore, a disposable laryngoscope blade for children is provided to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] Please refer to Figure 1-Figure 5 The utility model is a disposable laryngoscope blade for children, comprising: a catheter 1, a first tongue depressor 2 and a second tongue depressor 3, wherein an elastic silicone strip 4 is fixedly connected between the first tongue depressor 2 and the second tongue depressor 3, a piston groove 201 is provided inside the first tongue depressor 2 located at one side of the second tongue depressor 3, and the number of the piston grooves 201 is set. The first tongue depressor 2 is provided with a connecting groove 202 at the tail of the piston groove 201.

[0022] Combination Figure 3 and Figure 4 As shown, several piston grooves 201 are connected to the connecting groove 202, so as to facilitate the gas to enter each piston groove 201, and the piston groove 201 is slidably connected with the piston body 301, and the second tongue depressor 3 is fixedly connected with the sliding rod 302 on the side facing the piston groove 201, and the sliding rod 302 is fixedly connected with the piston body 301 at one end inside the piston groove 201.

[0023] Combination Figure 1 and Figure 2 As shown, the outer side of the elastic silicone strip 4 is flush with the first tongue depressor 2 and the second tongue depressor 3, so that the elastic silicone strip 4 can ensure that the first tongue depressor 2, the elastic silicone strip 4, and the second tongue depressor 3 are an integral structure, which is easy to use. The catheter 1, the first tongue depressor 2 and the second tongue depressor 3 are all made of highly transparent plastic. The tail of the catheter 1 is connected to a fixed sleeve 5, and laryngoscope bayonet holes 6 are symmetrically opened on both sides of the fixed sleeve 5. An inflation connector 7 is provided on one side of the fixed sleeve 5, and one end of the inflation connector 7 extends to the inside of the fixed sleeve 5 and is connected to the connecting groove 202. A guide groove 8 is provided on one side of the catheter 1.

[0024] Specifically, when the utility model is used, the laryngoscope tip is first inserted into the catheter 1 through the laryngoscope bayonet 6, and the laryngoscope is fixed in position on the laryngoscope bayonet 6 on the fixed sleeve 5, and then the external inflation tube is connected to the inflation connector 7 on the fixed sleeve 5. Before the laryngoscope blade is inserted into the throat, air can be firstly evacuated through the external inflation / evacuation device, so that the inside of the connecting groove 202 is in a negative pressure state, so that the piston body 301 can move toward the side of the connecting groove 202, and then the sliding rod 302 can be dragged by the piston body 301 to move, and the second tongue depressor 3 is brought closer to the side of the first tongue depressor 2 through the sliding rod 302, so that The distance between the outermost sides of the first tongue depressor 2 and the second tongue depressor 3 is shortened, so that it is more convenient to extend the first tongue depressor 2, the catheter 1 and the second tongue depressor 3 as a whole (laryngoscope blade) into the throat. After extending into the throat, in order to facilitate observation, the inflation / evacuation device can be controlled to inflate, so that the gas enters the connecting groove 202, so that the pressure in the connecting groove 202 increases and pushes the piston body 301, and then the piston body 301 pushes the sliding rod 302, and the second tongue depressor 3 is pushed away from the first tongue depressor 2 through the sliding rod 302, so that the distance between the outermost sides of the first tongue depressor 2 and the second tongue depressor 3 is widened, and the throat can be opened for easy observation.

[0025] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0026] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
