Detailed ways

In order to make it easy to understand the technical means, creation features, achievement goals and effects realized by the present invention, the present invention will be further described below with reference to the specific figures.

As shown in FIGS. 1-3 , the present invention provides a positioner for abdominal subcutaneous rotation injection, which includes an upper ring frame 100 and a lower ring frame 200 that are matched. One side of the lower ring frame 200 is hinged with the upper ring frame 100 , and the lower ring frame 200 is also provided with a plurality of locking pieces for the movable upper ring frame 100 and the lower ring frame 200 The positioning plate 400 is clamped and clamped between the upper ring frame 100 and the lower ring frame 200 through the locking member and can be detachably connected. The positioning plate 400 is circular and can be made of hard cardboard. The positioning plate 400 is provided with at least six dividing lines 410 with the center of the positioning plate 400 as the intersection point, so that the interior of the positioning plate 400 is equally divided into twelve sectors 411 . The positioning plate 400 is concentrically distributed with positioning holes 420 located in the middle of the positioning plate 400 , and also has circular marking lines 430 concentrically distributed and adjacent to the edge of the positioning plate 400 . The area between the marking line 430 and the positioning hole 420 is a hollow structure, and there are two partition lines 440 distributed in each of the sectors 411 , and the partition lines 440 are from the center of the circle to the inner edge of the positioning plate 400 distribution, the two partition lines 440 equally divide the sector 411 into three injection intervals 441, and also equally divide the area between the edge of the positioning disc 400 and the marking line 430 in each sector 411. Three marked areas 431.

With the above structure, the positioning plate 400 is sandwiched between the upper ring frame 100 and the lower ring frame 200, and then the positioning hole 420 on the positioning plate 400 is aligned with the navel of the patient's abdomen. Each sector 411 on the positioning plate 400 is divided by two column lines 440 to form three equally divided injection intervals 441, and each injection interval 441 has a corresponding marking area 431, so that each sector 411 Early, mid and late injection locations are located. The medical staff injects the needle from the injection section 441, and after completing the drug injection operation, draw a "√" or other pattern in the mark section 431 corresponding to the injection section 441 to mark the injected mark. In the next injection operation, the medical staff can use the positioning dial 400 as a dial, and continue the clockwise rotation method. During the treatment cycle, the injection position of the abdomen can be rotated. Even if different injection personnel perform subcutaneous injections, they can avoid the same The site is repeatedly injected to reduce the occurrence of adverse reactions and ensure drug absorption. After the positioning plate 400 is replaced, the positioning device can be used repeatedly, which saves costs.

As one of the optional implementations, an indicator line 110 is provided on the top surface of the upper ring frame 100 , and a chute 120 is further provided on the top surface of the upper ring frame 100 , and a movable movable groove is installed in the chute 120 The mark indicates the needle 500 , and the mark indicates that the needle tip of the needle 500 faces the center of the circle of the upper ring frame 100 . The marker indicating needle 500 can slide and move under the push of an external force, and in the absence of external force pushing, the marker indicating needle 500 and the chute 120 remain relatively fixed. After the positioning hole 420 is aligned with the navel of the patient's abdomen, the indicator line 110 points to the patient's head, and the positioning is more accurate. The marking indicator needle 500 can more intuitively assist in marking the injection position of the last injection operation.

The locking member includes pin holes (not shown) distributed on the bottom surface of the upper ring frame 100 , and pin shafts 300 distributed on the top surface of the lower ring frame 200 . There are five pins 300 , two of which are distributed at the rear end of the lower ring frame 200 at intervals, the other two are distributed at the front end of the lower ring frame 200 at intervals, and the last one is distributed at the opposite end of the hinged end. A plurality of connecting holes 450 are distributed on the positioning plate 400 , and the pin shafts 300 pass through the connecting holes 450 . and the lower ring frame 200 is fixed. The pin shaft 300 is inserted into the connecting hole 450 and then engaged with the pin hole, and the distribution position of the pin shaft 300 can firmly lock the positioning plate 400 between the upper ring frame 100 and the lower ring frame 200 to avoid displacement.

A connecting piece 210 is fixed on both sides of the outer wall of the lower ring frame 200, and each connecting piece 210 is connected with an elastic fixing belt 600, and two fixing belts 600 are provided with Velcro for bonding. ; The front end of the outer wall of the upper ring frame 100 is also provided with a label sticking groove 220 . The basic information of the patient can be affixed to the groove 220 of the label sticker by a sticker, and the locator is connected and fixed by the fixing belt 600, so as to avoid the displacement of the locator and facilitate the injection.

The bottom surface of the lower ring frame 200 is connected with a circular silicone pad (not shown in the figure), and the silicone pad is in contact with the patient's abdominal skin, which can play an anti-slip effect and further enhance the fit effect of the positioner and the abdomen.
