Abstract
The utility model belongs to the class of medical appliances of physical methods. In order to overcome the defects that a laryngoscope in the prior art has weak illumination intensity, can not simultaneously supply oxygen to human bodies when used, has an unsteady light source because of the influence of a battery, and can not spray dopes to a glottis in time when the intubation is difficult, the scheme of the laryngoscope of the utility model is proposed. The utility model is composed of a laryngoscope handle, a laryngoscope lens and a light source, wherein, a controllable dope storing and spraying device and a charging device are arranged in the laryngoscope handle; the light source is transferred by optical fibers, a lamp bulb is provided with a switch of a normally open contact, and a dope spraying hole is connected with an oxygen supply passage. Therefore, the utility model has the advantages that the utility model can both supply the oxygen and spray the dopes, the illumination intensity of the light source is improved, and the light source is stable when the utility model is charged and used.
Description
This utility model belongs to a kind of medical machinery of physical method, and it relates to a kind of structure of laryngoscope.
Laryngoscope is a kind of instrument that makes cardio-pulmonary resuscitation, general anesthesia induction expose glottis when the gas intubate.The present homemade laryngoscope that uses in clinical exists 1. can not be to Invivo oxyger-supply in the intubate process; Be difficult to when 2. running into difficult intubation spray numb broken medicine to glottis immediately, easily cause malpractice; 3. the illumination of its illuminace component is poor, and the defective that is subjected to the influence in common batteries life-span that flashing is waited surely.The external laryngoscope that uses in clinical exists the unreasonable generation halation of 4. surface treatment, and influence is observed; 5. the dimensions that also exists eyeglass does not meet problems such as Chinese physiological feature.
The purpose of this utility model is to provide the scheme of this novel laryngoscope for overcoming five particular problem spies that aforesaid laryngoscope in use exists, it adopts and changes light-source structure, increase spray medicine facility, change measures such as surface treatment, to reach the purpose of improving the convenient use of performance.
By as above design, the novel laryngoscope that this programme provided is made up of mirror handle, eyeglass, light source portion branch, its concrete feature is: its mirror handle is the long tube of an elliptic cross-section, have controlled storage medicine chemical spraying device in the mirror handle, have the battery case of rectifier charging device, also have the Lights section of normally opened contact electric switch, its eyeglass part also is provided with the optical fibers that conducts light source, is provided with the atomizing medicine spraying tube road with oxygen supply pipeline UNICOM except that having Xiao's axle and connecting with the mirror shank portion the localized spring pearl mechanism.
Controlled storage medicine chemical spraying device in this programme by drug liquid tube, the soft lid of rubber, spring, and manual depression bar form, its drug liquid tube is that the aperture rear portion of dripping medicine is arranged is the big slightly pipeline of diameter to a front end, the outer rim of drug liquid tube cooperates with the endoporus of mirror handle, the soft lid of rubber is the elastic device of a medicated cap shape, and the internal diameter of soft lid and the external diameter of drug liquid tube closely cooperate.Adorn chargeable battery in its battery case, and be provided with the rectification circuit that integrated package is barricaded as, battery case lid is provided with the interface of power supply.Its Lights section is by bulb and move axially the socket that can open and close the normally opened contact switch and form, and socket is contained in the hole of mirror handle.Its optical fibers one end is aimed at bulb, and the other end leads to the place ahead of eyeglass.Its eyeglass becomes crooked ligule, with the mirror shank portion except that the open slot that has pin to connect and for connecting localized spring pearl and the groove, the passage of dress crooked light-transmitting fibre in front end has, the front end of the straight-through eyeglass of this passage, the rear portion of eyeglass has the oxygen supply passage with the oxygen hose connecting joint, this passage leads to the front end of eyeglass, and the opening of this passage is positioned at the place ahead of optical fibers termination.The oxygen supply passage communicates with the spray medicine mouth of mirror shank, and the oxygen supply passage before two pipelines are imitated mutually is the trunnion form of dwindling caliber.The outside polishing of eyeglass, its inner surface is done blasting treatment.
Adopt this programme can embody following superiority: 1. to adopt optical fibers conduction luminous energy to improve illumination, the convenient observation and operation; 2. have storage medicine spray medicine facility in the mirror handle, utilize the air-flow of oxygen supply to bring ejection anesthetics mist into, save the operation and the facility of its spray medicine, spray value is controlled, and is easy and simple to handle; 3. power pack adopts rechargeable battery, and time spent connection civil power can not replenish oxygen supply at any time, and voltage is stable during use, the battery long service life; 4. the shape and the surface treatment of eyeglass part are reasonable, have avoided halation phenomenon, and assurance function is intact.
Fig. 1 is the structure cutaway view of this programme laryngoscope;
Fig. 2 is the situation of analysing and observe of eyeglass part, and the localized situation that connects is described.
Fig. 3 is the electrical schematic diagram of rectifying part.
The structure of accompanying drawings present embodiment and working condition.Mirror handle (1) and eyeglass part (2) connect by Xiao's axle (3), connect the location with spring pearl (4) and groove, connect that mirror handle front portion is pressed into bulb (5) when being duty (locations of structures as shown), make normally opened contact switch (6) combination, light bulb.Battery (7) adopts rechargeable battery, and there is the fairing (9) of charged source interface (8) at the battery case rear portion.The spray medicine mouth of drug liquid tube (10) communicates with oxygen supply passage (11), and soft lid (12) tightly is enclosed within on the drug liquid tube, and manual depression bar (13) contacts with soft lid by spring (14), and medicinal liquid oozes during the hand depression bar.Optical fibers (15) and bulb over against, luminous energy can be passed forwards.
The mirror shank portion adopts metal package to electroplate, and eyeglass partly adopts stainless steel material.The overall dimensions of this programme is 190 * 140 * 50mm, and the pilot sample of this programme is rational in infrastructure through probationary certificate, and is easy to use, function admirable.The further improvement of this programme will be used imaging fiber technology and Microsoft's axle control eyeglass curvature technology, further improve its performance.
