Description
Technical field
The present invention relates to a kind of lift surgical anaesthesia headstock.
Background technology
, it is necessary to use many narcotics, apparatus during preanesthesia of performing the operation, and rhythm of performing the operation is often very tight
Gather, seize every minute and second, for the ease of operation, can be layered on disinfecting towel with patient by doctor sometimes, and by the medication of anesthesia induction when institute
Related equipment when product holding tray is to general anesthesia is (such as：Trachea cannula etc.) it is placed on disinfecting towel, on the one hand this operation does not meet rule
Model (is contrary to love and hinders idea and medical asepsis principle), and another aspect pallet is not easy to place steady.
Patient for partial insertion trachea cannula is, it is necessary to lung ventilator is supported immediately by screwed hose, and is breathed
Machine is generally located on the operation table side in front of patients head, and screwed pipe needs to apply towel to connect trachea cannula through operation, but
Operation is applied towel moiety by weight and is undertaken on screwed pipe, there is no special implement to be fixed for screwed pipe upper end at present, therefore
When screwed pipe is rocked due to operation technique, can give screwed pipe upper end and surface bigger pressure, and be likely to occur pipeline
Tangle, in some instances it may even be possible to the situation that trachea cannula is dragged out occur, cause huge potential safety hazard, be unfavorable for smoothly entering for operation
OK.
In order to solve the problems, such as above-mentioned potential safety hazard, the utility model patent of Publication No. CN 204319187 discloses one
The lift surgical anaesthesia headstock is planted, the headstock includes the cross bar of symmetrically arranged expansion link and connection expansion link, on cross bar
It is provided with contractile support covering of the fan；It is also equipped with omnidirectional mechanism on cross bar, omnidirectional mechanism is connected post by pole, fixed
Soft card is provided with post, described support covering of the fan includes being arranged on the rotating shaft in the middle part of cross bar, and multiple size phases are provided with rotating shaft
Same flabellum, wherein two flabellums positioned at bottom are fixedly connected with cross bar, remaining flabellum is symmetricly set on when being not switched on
Rotating shaft both sides, the flabellum of rotating shaft both sides can be unfolded into half covering of the fan along the direction of rotation of rotating shaft, and two and half covering of the fans are by fixing
Card is connected to become support covering of the fan.After supporting covering of the fan to strut, placement space is constituted on covering of the fan, can mainly play two effects：
First, towel is applied in operation to be needed to be bypassed from the headstock, therefore after supporting covering of the fan to strut, then carry out deposited towel of performing the operation
Placement, then due to support covering of the fan effect, it will support covering of the fan below, i.e., cloth position in patient face struts one relatively
Space wide, makes patient face cloth not blocked due to sagging deposited towel edge, maintains the circulation of air and breathe smooth, also allows for exhaling
The setting of suction machine pipeline；Second, when deposited towel is covered after supporting on covering of the fan, after then can laying disinfecting towel thereon, place operation
Pallet；The set location of the headstock determines its closer operative site, thus after operation tray is placed, in easily facilitating operation
Medicine, apparatus fetch process.
Spacing of the height of above-mentioned covering of the fan between the face of patient needs to be adjusted by expansion link, by the patent
Diagram can be seen that expansion link and is made up of the inner tube that outer tube and one end are inserted into outer tube, and a screw thread is orientated as to inner tube
The knob on outer tube wall face is connected to, it is internal in radial direction by knob when the Height Adjustment of inner tube is to correct position
Pipe apply pressure and by the positioning of inner tube.Above by the positioning method of knob the positioning of inner tube can be caused unreliable, its reason
It is that although knob contact with inner tube outer circumference surface is that face contacts, but the area for contacting between the two is smaller, this positioning side
Formula it is obvious unreliable, add after medicine, apparatus and other items are placed on covering of the fan, these articles impose axial pressure to inner tube
Power, it is easier to cause inner tube slide downward, so, final result be medicine, apparatus and other items fall patients head or
With, patient is caused harm, therefore, it is necessary to consider to be improved the expansion link of this anesthesia headrest.
The content of the invention
It is an object of the invention to provide a kind of lift surgical anaesthesia headstock, the headstock of the invention after being lifted,
Be not in the situation of slip, have the advantages that steadiness is high.
The technical scheme for solving above-mentioned technical problem is as follows：
