Sensor, specifically can be vacuum electric capacity sensor or diaphragm pressure sensor, pressure sensor 72 is set to breastbone
Centesis operator is between the preceding power piece of puncture needle.When operator implements sternoparacentesis, the hand of operator holds puncture
Needle handle portion, and the power on piece before puncture needle is contradicted, in puncture process, operator needs in puncture needle needle handle portion and preceding power on piece
Apply strength to push puncture to be needled into breastbone, when puncture is needled into ossis, since needle point does not have the blocking of sclerotin, implements
The operator of sternoparacentesis can experience resistance disappearance, i.e., power piece acts on the pressure of operator on hand before operator can experience
Power moment becomes smaller.Therefore sternoparacentesis operator being arranged between the preceding power piece of puncture needle in pressure sensor 72 can have
Effect perception puncture needle enters moment of ossis, is embodied in pressure sensor 72 to receive the moment that pressure becomes smaller rapidly defeated
Signal sharply changes out.The sharply change of output signal is by the way that at wire transmission to pressure prompting device 71, pressure prompting device 71 is sent out
Corresponding signal prompt operation puncture needle is out to be pierced into ossis.
As an improvement specific embodiment, it is fixed that the guide part 5 is arranged perpendicular to the side of displacement prompting device 54
Position hole, the location hole are connected to displacement prompt tank 52, and what setting was connected through a screw thread at location hole marks closely screw 55, described
Mark closely the round table-like tightening knob of one end setting that screw 55 exposes to location hole.
In the use of the present invention, location hole and marking closely the setting of screw 55 for being displaced the positioning of prompting device 55.By breastbone
Puncture needle is placed in guide groove 51 and the second guide groove 541, the needle contact skin of sternal puncture needle, moving displacement prompting device 54
The preceding power piece of sternal puncture needle is contacted, the position for being displaced prompting device 54 at this time relative to displacement prompt tank 52 is zero point, is communicated
11 side moving displacement prompting device 54 of hole screws the tightening knob for marking closely screw 55, marks closely screw 55 and contradict displacement to set distance
Prompting device 54 and locking.Implement sternoparacentesis, is pierced into ossis when sternal puncture needle fails, is persistently pierced into sqternal puncture
Needle to its preceding power piece contradicts displacement prompting device 54, prompts operator to puncture unsuccessful, easily pierces if sternal puncture needle continues to be pierced into
Wear breastbone.
As an improvement specific embodiment, the cue mark be displaced 54 surface of prompting device setting along described
The axial length scales 543 of second guide groove 541.
In the use of the present invention, the seamed edge is directed toward displacement 54 table of prompting device using a seamed edge of guide part 5 as indicator
The length scales 543 in face, the corresponding reading of length scales 543 position current for displacement prompting device 54, displacement prompting device 54
The mobile change for being reflected in the reading of length scales 543.The setting of length scales 543 facilitates operator to set displacement prompting device 54
Position and the specific location that displacement prompting device 54 is conveniently understood by reading.
As an improvement specific embodiment, the cue mark be guide part 5 on be displaced 52 side table of prompting device slot
The second axial length scales of prompt tank 52 are moved on the edge of face setting.
In the use of the present invention, the second length scales are set to the surface of guide part 5, corresponding 54 surface of displacement prompting device
It needs that cue mark is arranged, operator is facilitated to indicate the position of setting displacement prompting device 54 by the second length and conveniently pass through
Reading understands the specific location of displacement prompting device 54.
As an improvement specific embodiment, the pressure prompting device 71 be indicator light or buzzer.
In the use of the present invention, that is, change amount signal is greater than setting when the information instantaneous variation of pressure sensor output is big
Value, then driving pressure prompting device 71 works, and the pressure prompting device 71 is indicator light or buzzer, and it is bright to be embodied in indicator light
Rise or extinguish or buzzer work.
As an improvement specific embodiment, further include auxiliary retention portion 3, the auxiliary retention portion 3 be set to
The sheet or strip gel of 1 both sides of the edge of pedestal or the whole circle edge of pedestal 1.
In the use of the present invention, being coagulated in the whole circle edge setting sheet in 1 both sides of the edge of pedestal or pedestal 1 or the medical of strip
Glue, medical gel can be adsorbed on patient skin surface, further strengthen the fixation of pedestal 1, it is ensured that sternal puncture needle is being oriented to
The stability of pedestal when 5 guiding role of portion.
As an improvement specific embodiment, further include anti-delinking part 4, the anti-delinking part 4 it is pairs of be set to pedestal 1
The corresponding position in two sides, the anti-delinking part 4 is in a strip shape, and pairs of anti-delinking part 4 can connect circlewise, the band-like anti-delinking part
4 are connected by knotting or are connected by eye-splice.
In the use of the present invention, in the corresponding position in pedestal two sides setting strip can be around the anti-delinking part of patient body
4, pedestal 1 is fixed on patient skin surface when in order to the connection of anti-delinking part 4 circlewise, it is ensured that pedestal 1 will not occur and fall off shadow
The accident that sternoparacentesis is normally carried out is rung to occur.
Anti-delinking part 4 is pairs of elongated cloth, and anti-delinking part 4 can pass through connection or the eye-splice connection of knotting.Using knotting
The mode of connection is simple and easy, and is simple to manufacture, and can reduce manufacturing cost, in actual use more flexibly.Using eye-splice
The mode of connection intersects the mode for the connection that knots, more convenient in the disassembly that operation is completed, high-efficient.
As an improvement specific embodiment, the setting of 63 surface of said inner tube is used to indicate guide part 5 and pedestal 1 and presss from both sides
The scale at angle.
In the use of the present invention, being used to indicate the scale of guide part 5 Yu 1 angle of pedestal in the setting of 63 surface of inner tube, specifically
Scale can be by the way that by way of coding or the mode of laser marking is arranged, scale can use angular values and scale knot
The mode of conjunction.The setting of scale is conveniently adjusted the angle of guide part 5 and pedestal 1 to needs.
