Description

Medical rigid optical wand

Technical field

The utility model is related to a kind of optical wand, especially a kind of general anesthesia type trachea cannula light bar belongs to medical device technology Field.

Background technology

At present, tool used in trachea cannula has：Direct laryngoscope, Bronchofiberscope, visible laryngoscope, integral type optical wand etc..But All there are certain limitations and deficiency in these tool Clinical practices.1st, common laryngoscope is to difficult airway patient, successful intubation It is low, and over-exposure pars oralis pharyngis is usually needed to easily lead to oral cavity tissue damage, it is not applied in addition, being limited patient to mouth opening. 2nd, branchofiberoscope operation difficulty is big, needs abundant clinical manipulation experience, and the operating time is longer, intubation defeat rate compared with It is high.3rd, visible laryngoscope is limited patient to mouth opening and does not apply to, to patient cannula's success rate more than difficult airway and oral secretion It is relatively low.4th, optical wand (also referred to as light rope, intubation headlamp, light wand) guide cannula technology is one for clinical anesthesia, urgency Repair the new technology of Soviet Union and airway constriction patient's trachea intubation.During intubation, observed using the principle of neck soft tissue light transmission Guiding tracheal catheter enter tracheal strips, provide accurate position guide for trachea cannula, thus can effectively improve be intubated into Power.Intubation optical wand is an integral structure on the market at present, and barred body and handle are connected as a single entity, and is existed because of disinfection inconvenience, no Thoroughly lead to the risk hidden danger of cross-infection.Therefore existing intubation tool is required further improvement, improves intubation speed and effect Rate meets clinical needs, and reduces medical-risk.

Invention content

The purpose of this utility model is that open one kind is of simple structure and low cost, operation is easy, disinfection thoroughly conveniently, is kept away Exempt from cross-infection, applied widely, the high hard optical wand of safety coefficient.

The technical solution adopted in the utility model is as described below：

The utility model use high-brightness LED sidelight hard optical wand, including optical wand barred body, illuminator, transparent arc-shaped cover, It is intubated locator, T-shaped handle, optical fiber, power supply, switch, circuit board, conducting wire etc..Optical wand barred body is dilute for anti-corrosion good toughness Native compo pipe makes, and leading portion bends to a radian (angle) being adapted with the physiological angle of human body, preferred embodiment 80 ~120 degree；Further, preferred embodiment is 96~106 degree.

Optical wand barred body head is fixedly connected with an arc-shaped cover made of corrosion resistant transparent material, and optical wand barred body tail end is by can The slip interface connection T-handle of dismounting, slides interface and is fixed with snap lock.T-shaped handle is cavity housing, uses insulation material Material makes, generally plastics, rubber, wood materials etc..An optical fiber is assigned in optical wand barred body, one end of optical fiber is stretched In the transparent arc-shaped cover for entering optical wand barred body top, the other end is connect with illuminator.T-handle sky intracavitary unit illuminator, power supply, Circuit board and switch are attached with conducting wire between them；Power supply is made of rechargeable battery and battery case, illuminator led Light bulb or laser can emit and be mutually 90 degree of feux rouges.Switch button is placed in the outside of T-shaped handle one end.

T-handle provides activity space for barred body sliding extension, and also more conducively intubation is convenient.

Optical wand barred body diameter is further reduced, can be applied in the endotracheal intubation of child patient.

The utility model have of simple structure and low cost, operation easily, positioning it is clear accurate, disinfection easily and thoroughly, it is suitable With the characteristics of in extensive range, safety coefficient is higher.
