Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary positioner for intramuscular injection. Background Art

[0002] Intramuscular injection is a commonly used drug injection treatment method. The sites of intramuscular injection can be the gluteus maximus, gluteus medius, gluteus minimus and vastus lateralis. For these main injection sites, the commonly used auxiliary injection positioning methods are divided into the following types:

[0003] 1. Two positioning methods for gluteus maximus injection: cross method, draw a horizontal line from the apex of the gluteal cleft to the left or right, and then draw a vertical line from the highest point of the iliac crest downward to divide one buttock into four quadrants. The upper outer quadrant, avoiding the inner corner, is the injection site; line method, take the upper outer 1 / 3 of the line connecting the anterior superior iliac spine and coccyx as the injection site; 2. Two positioning methods for gluteus medius and gluteus minimus injection: angle method, place the index finger and middle finger (based on the patient's finger width as the standard) on the anterior superior iliac spine and the lower edge of the iliac crest respectively. The triangular area formed by the iliac crest, index finger, and middle finger is the injection site; three-finger method, three horizontal fingers lateral to the anterior superior iliac spine (based on the patient's finger width as the standard) is the injection site; vastus lateralis injection positioning method: nine-point positioning method, on the anterolateral side of the middle thigh, generally for adults, take 10 cm below the hip joint to 10 cm above the knee joint, with a width of about 7.5 cm.

[0004] All of the aforementioned intramuscular injection location methods require clinical nurses to visually inspect or rely on their experience.

Then, place the locator on the patient's buttocks and rotate the movable telescopic ruler 4 to measure the triangle formed by the anterior superior iliac spine and the lower edge of the iliac crest. This is the injection site.

[0025] Example 2

[0026] On the basis of the aforementioned embodiment 1, the left telescopic ruler 2, the right telescopic ruler 3, and the movable telescopic ruler 4 of the intramuscular injection auxiliary positioning device of this embodiment 2 all have a multi-stage telescopic structure, so that the left telescopic ruler 2, the right telescopic ruler 3, and the movable telescopic ruler 4 can be unidirectionally adjusted in the use range, as follows:

[0027] like Figure 3 As shown, the multi-stage left telescopic rulers 2 are nested step by step and slide by clearance fit, the left inner ruler 21 of the first stage (sleeved on the outermost layer) is embedded in the left inner cavity of the protractor 1 and is slidably connected to the protractor 1, the multi-stage right telescopic rulers 3 are nested step by step and slide by clearance fit, the right inner ruler 31 of the first stage is embedded in the right inner cavity of the protractor 1 and is slidably connected to the protractor 1, when the left telescopic ruler 2 and the right telescopic ruler 3 are fully extended, the maximum measuring range of the left telescopic ruler 2 to the right telescopic ruler 3 is 50 cm; the movable telescopic ruler 4 includes a movable outer ruler 41 and a plurality of movable inner rulers 42, the movable outer ruler 41 and the plurality of movable inner rulers 42 are nested step by step and slide relative to each other, and when the movable telescopic ruler (4) is fully extended, its maximum measuring range is 20 cm. One end of the movable outer ruler 41 away from the movable inner ruler 42 can be rotatably connected to the center point of the protractor 1. Specifically, a through hole can be opened in the movable outer ruler 41 and the protractor 1 and a pin can be passed through the through hole to hinge the movable telescopic ruler 4 so that the movable telescopic ruler 4 rotates with the center point as the rotation center.

[0028] The method of using the intramuscular injection auxiliary locator of this embodiment 2 is the same as that of embodiment 1.
