When the specific location of liquid port port seat, medical staff's left index finger is inwardly squeezed with thumb, so that the first compression bar 3 and the second compression bar
The distance between 5 shorten, while first clamping plate 1, second clamping plate 2, the first compression bar 3 and the second compression bar 5 are rotated around pin shaft 6,
So that the distance between first clamping plate 1 and second clamping plate 2 increase, then make first clamping plate 1 and second clamping plate 2 across patient skin
Transfusion port port seat is clamped, since the outer surface of first clamping plate 1, second clamping plate 2, the first compression bar 3 and the second compression bar 5 utilizes stickup
Layer 9 has coated one layer of silica gel sheath 10, therefore silica gel sheath 10 is in contact with skin at this time, mitigates the discomfort of patient, then unclamps the
One compression bar 3 and the second compression bar 5 reset at this time due to having clamped transfusion port port seat between first clamping plate 1 and second clamping plate 2
Spring 12 is in compressive state inside limit plate 11, and reset spring 12 generates an opposition, can make first clamping plate 1
Transfusion port port seat is clamped with second clamping plate 2, while limit plate 11 limits reset spring 12, and reset spring 12 is avoided to occur
Buckling maintains to stablize, pulls lever 15 then up, and fixed pole 14 is fixed on by the threaded function between connecting rod 13
On pin shaft 6, lever 15 can be extracted out inside fixed pole 14, band 16 wicking height of moving base bar, when need to observe transfusion port port seat
When the vascular distribution of surrounding, perspective imaging case 23 is rotated on vertical plane, so that rubbing between card slot 22 and connector 19
Rotation, thus it is possible to vary the angle that perspective imaging case 23 and horizontal plane are formed, in the horizontal plane rotating horizontal pole 18, pedestal bar 16 and set
It rotates between ring 17, thus it is possible to vary then two pole of infrared ray of model IR is opened in the horizontal position of perspective imaging case 23
Pipe 26, infrared diode 26 issue infrared light, are radiated on patient skin, due to the oxyhemoglobin in human vas
And go blood-nourishing Lactoferrin relative to its hetero-organization, the ability for absorbing infrared light is stronger, therefore the infrared light reflected is less, shape
At blood vessel shade, and since the injection seat base interior of transfusion port contains metal, and the ability of Metal absorption infrared light also compared with
By force, therefore injection seat pedestal also will form shade, and model OV7950 imaging sensor 28 can receive the red of skin reflex
Outside line optical information, and the picture processing chip 25 of model OV7640 is passed information to, picture processing chip 25 is to image
Information is analyzed and processed, and the projection lens 27 for passing information to model CW-0620-2MP is projected, at this time blood
Pipe distributed image projects on the skin of the patient, avoids blood vessel at this time and is punctured, completes entire transfusion port port like this
Seat punctures the use process of auxiliary locator.
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.
