Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

Example (b):

as shown in fig. 1-3, an indwelling needle holder based on an ultrasonic probe comprises a holder body 1, the upper part of the front surface of the holder body 1 is an inclined surface inclined toward the inside of the holder body 1, the lower part of the front surface of the holder body 1 is a vertical surface, the top surface of the holder body 1 is an inclined surface inclined toward the back surface, the holder body 1 is provided with a mounting groove 11 with a bottom surface and a front surface opened, two mounting protrusions 12 are arranged on two sides of the inner surface of the mounting groove, the mounting groove 11 and the mounting protrusions 12 are matched with a fixing frame on the existing ultrasonic probe, the indwelling needle holder further comprises a cover plate 2 and a wedge block 3, the holder body 1, the cover plate 2 and the wedge block 3 are all made of plastic materials, the tail end of the cover plate 2 is connected with the tail end of the top surface of the holder body 1, the upper surface of the cover plate 2 is provided with a, the guide pin groove 21 is a cylindrical groove, and the radius of the guide pin groove 21 is matched with the radius of a commonly used indwelling needle;

the top surface of the bracket body 1 is also provided with a limiting groove 13, the wedge block 3 is arranged in a gap between the bracket body 1 and the cover plate 2, and the bottom of the wedge block 3 is provided with a limiting lug 31 matched with the limiting groove 13.

Spacing recess 13 and spacing lug 31's quantity more than or equal to 3, the connected mode of apron 2 and support body 1 connects for moulding,

apron

2 and 1 trailing end connection of support body promptly, leave the clearance that makes things convenient for 3 male wedges between the both head ends, rely on plastic material's deformation, make voussoir 3 after inserting, the clearance between the upper surface of apron 2 and support body 1 increases the change, thereby the angle of 2 upper surfaces of adjustment apron, the angle that has also changed guide pin groove 21, the angle of inserting of needle has been changed to keep somewhere, thereby the better angle of puncturing of carrying on, guarantee the accuracy of puncture.

The fixing frame at the top of the optimized ultrasonic probe is a cuboid bump, and the size of the fixing frame is matched with that of the mounting groove 11.

The front surface of the bracket body 1 is provided with the inclined upper part and the vertical lower part, so that a certain space can be reserved at the top of the bracket body 1 when the bracket body 1 is pushed into the fixing frame at the top of the ultrasonic probe from the mounting groove 11 on the front surface of the bracket body 1 for fixing, and the operation is more convenient; will the utility model discloses fix on ultrasonic probe through mounting groove 11 and installation lug 12, confirm vascular position and vascular thickness with the help of ultrasonic probe's function, select the degree of insertion of voussoir 3 in order to adjust the angle of guide pin groove 21 as required, carry out the puncture of safe needle of keeping somewhere more ready, because apron 2 is parallel with the top surface of support body 1, when voussoir 3 inserts the space between apron 2 and support body 1, apron 2 will take place to deform, voussoir 3 cooperates the position that is used for fixing voussoir 3 through spacing lug 31 of itself bottom and spacing recess 13 of the top surface of support body 1, and then the angle of control guide pin groove 21, thereby change the puncture angle of keeping somewhere the needle, satisfy various demands; the number of the limiting grooves 13 and the limiting bumps 31 is more than or equal to 3, so that the angle of the guide pin groove 21 can be more finely controlled, and the accuracy is higher; the connection mode of the cover plate 2 and the bracket body 1 is plastic connection, so that the deformation between the cover plate 2 and the bracket body 1 is better ensured, and the wedge 3 can be fixed more tightly when the wedge 3 is inserted.

Before carrying out the puncture injection, will earlier the utility model discloses a mounting groove 11 and installation lug 12 are fixed on ultrasonic probe's mount, and the syringe needle that will keep somewhere the needle inserts guide pin groove 21 in, use ultrasonic probe to survey and seek the position that finds blood vessel, will keep somewhere to puncture the position and puncture, then carry out the displacement with ultrasonic probe down, keep somewhere the syringe needle and will break away from out in the opening of guide pin groove 21 upper end, just accomplished the puncture.

It should be noted that the front and back sides are based on the description of the drawings, and the head end is the front position.

The utility model discloses compare in prior art's beneficial effect for can be more accurate look for the blood vessel and differentiate hematal thickness for puncture injection accuracy more, and carry out the angularly adjustable of puncture, make puncture injection accuracy more, safety.

It is right above that the utility model provides an keep somewhere syringe needle support based on ultrasonic probe has carried out detailed introduction. The description of the specific embodiments is only intended to facilitate an understanding of the method of the invention and its core ideas.
