Description

Laryngoscope

Technical field

This utility model belongs to technical field of medical instruments, particularly relates to laryngoscope.

Background technology

Endotracheal intubation is surgery anesthesia, cardio-pulmonary resuscitation, prevent from inhaling and respiratory dysfunction etc. is urgent by mistake rescues In an important technology.During the oral or nasal insertion of endotracheal tube, must be through the glottis of throat, glottis is the narrowest in throat Position, position is deep and upper end is blocked by the root of the tongue and epiglottis, and endotracheal tube is not easy through glottis, and is mistakenly inserted in esophagus.For Prevent endotracheal tube to be mistakenly inserted esophagus or damage glottis, in the catheterization procedure of endotracheal tube, need the auxiliary at laryngoscope Under carry out intubation, laryngoscope is the instrument appearing glottis when tracheal intubation, is now widely used in various medical institutions In.

Laryngoscope is mainly made up of handle and laryngoscope blade two parts, laryngoscope blade for dial gear epiglottis and on carry the root of the tongue with fully sudden and violent Dew glottis, simultaneously with illuminating lamp on laryngoscope blade, in order to observes cavity interior structure.Existing laryngoscope, the most only possesses aobvious The function of dew glottis, when neonatal cardio-pulmonary resuscitation operates, usually appears its short slab, owing to neonatal cardio-pulmonary resuscitation operates Need the most accurately to complete, therefore save the key that the time is Neonatal Cardiopulmonary Resuscitation, when cardio-pulmonary resuscitation, usually need To clear up by foreign body intraoral to baby, the most just can carry out intubation, this process needs in foreign body cleaning and inserts Use laryngoscope twice during pipe, not only neonatal vocal cords produced secondary injury, and wastes the time of overall cardiorespiratory recovery, There is a possibility that neonate leaves over lower lifelong disease, even affect neonatal survival rate.

Utility model content

The purpose of this utility model embodiment is to provide a kind of laryngoscope, it is possible to carry out oral foreign body before intubation Cleaning, reduces the overall time of intubation.

This utility model embodiment is achieved in that

Laryngoscope, including handle and laryngoscope blade, laryngoscope blade is L-shaped with handle to be connected, and also includes: suction pipe, and described suction pipe is along hands Handle axially arranged, and the shape pressing close to laryngoscope blade extends, suction pipe mouth is positioned close to the bottom of laryngoscope blade.

Wherein, having negative pressure switch in handle surfaces, negative pressure switch connects with described suction pipe.

Described laryngoscope, also includes silica gel sheath, and it is socketed on the surface of laryngoscope blade.

Wherein, described suction pipe is fixed on the outside of described silica gel sheath.

Wherein, described silica gel sheath is socketed on handle.

Wherein, described suction pipe is fixing in the handle.

Described laryngoscope, also includes flexible pipe, and described suction pipe is connected with negative pressure source by flexible pipe.

Described laryngoscope, also includes that Portable negative pressure source, described suction pipe connect with Portable negative pressure source.

Wherein, described Portable negative pressure source is provided with its switch connecting with suction pipe or cutting off of control.

Described laryngoscope, also includes illuminating lamp and battery, and illuminating lamp is fixed on laryngoscope blade, and battery is built-in in the handle, Illuminating lamp electrically connects with battery.

This utility model embodiment absorbs mouth by arranging foreign body cleaning on laryngoscope blade, adds negative pressure when using laryngoscope Intraoral foreign body can be cleared up, and then carry out intubation, be not required to secondary and use laryngoscope, save intubation The overall time；Laryngoscope blade is set with silica gel sheath, prevents the rigidity of laryngoscope blade from directly contacting vocal cords, damage vocal cords, newly The vocal cords of raw youngster, it is achieved thereby that the buffer protection function to vocal cords；Handle offers negative pressure switch mouth, controls negative in real time Pressure size, effectively clears up oral foreign body；Handle arranges Portable negative pressure source so that it is use and do not limited by locus, increase Add the degree of freedom that laryngoscope uses.

Fig. 1 is laryngoscope overall schematic one of the present utility model；

Fig. 2 is laryngoscope overall schematic two of the present utility model.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.

Below in conjunction with specific embodiment, of the present utility model implementing is described in detail:

As depicted in figs. 1 and 2, laryngoscope, including handle 2 and laryngoscope blade 1, laryngoscope blade 1 is L-shaped with handle 2 to be connected, and also wraps Include: suction pipe 4 and silica gel sheath 3, axially arranged along laryngoscope blade 1 of described suction pipe 4, and the shape pressing close to laryngoscope blade 1 extends, suction pipe mouth It is positioned close to the bottom of laryngoscope blade 1.Handle 2 surface has negative pressure switch 5, negative pressure switch 5 and the control of negative pressure source Device electrically connects, controller control the vacuum magnitude of suction pipe 4.Silica gel sheath 3 is socketed on the surface of laryngoscope blade 1, it is also possible to simultaneously It is socketed on handle 2.Described suction pipe 4 can be fixed on the outside of described silica gel sheath 3, it is also possible to is fixed on laryngoscope blade 1 and handle 2 In (as shown in FIG.).

In Fig. 1, laryngoscope also includes that flexible pipe 6, described suction pipe 4 are connected with negative pressure source by flexible pipe 6.

In Fig. 2, laryngoscope also includes that Portable negative pressure source 7, described suction pipe 4 connect with Portable negative pressure source 7, described Portable negative pressure source 7 are provided with its switch (not shown) connecting with suction pipe 4 or cutting off of control.

For the ease of observing the internal structure in oral cavity, described laryngoscope, also include illuminating lamp (not shown) and battery (not shown), illuminating lamp is fixed on laryngoscope blade 1, and battery is built in handle 2, and illuminating lamp electrically connects with battery.

In embodiment of the present utility model, first pass through that to be provided with absorption tube on laryngoscope blade clear so that oral cavity is carried out foreign body Reason, increases negative pressure switch, makes vacuum magnitude controlled, it is easy to operation, and laryngoscope blade puts silica gel sheath, it is achieved laryngoscope blade and vocal cords Soft contact, effectively prevents vocal cords from sustaining damage, and increases Portable negative-pressure source, makes the use of laryngoscope not restricted by space.

The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
