When fluid temperature of the present invention is too low, annular-heating piece 83 is heated, and passes through annular 82 quick conductive of thermally conductive sheet and fluid injection
Medical fluid sufficient heat exchange in cylinder 6 when needing fluid injection, pushes away column 71 and round push plate 72 moves up and down to be increased to preference temperature,
Due to being stressed directly in the stability in the plane of round push plate 72, guaranteeing sliding, due to annular rubber ring 73 while force
It is slidably connected on the inner wall of fluid injection cylinder 6, propulsive liquid frustum 74 and the conical shell of 6 bottom of fluid injection cylinder are coupled, and are guaranteed to fluid injection
The pressure of stablizing of medical fluid is released in cylinder 6, and medical fluid is conveyed by hydrojet channel 13, sparge pipe 15 and perfusion tube 161, passes through homogenizing plate
After 162 flow, uniformly sprayed by through-hole 164 equally distributed on 163 outer surface of jet head, personnel, which will hold hand-held pipe 25, to inhale
Liquid head 26 is placed on hydrops position, and asepwirator pump 201 operates, and by tracheae 202 to 21 air-breathing of liquid storage bottle, is formed inside and outside liquid storage bottle 21 and is born
Pressure difference passes through imbibition sebific duct 24, screwed pipe 23, mounting cylinder 22, imbibition channel 14, screw shell 17, connecting tube 18 and outlet tube
203 are quickly evacuated to the hydrops of inspiration in liquid storage bottle 21, are not in while spray under the action of imbibition sebific duct 24
The generation of imbibition range limited situation.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
