Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of subcutaneous injection, in particular to a needle position fixing device. Background Art
[0002] Many of the therapeutic drugs used by the Department of Breast and Thyroid Medicine for breast cancer patients require subcutaneous injection, and the inclination angle is usually between 30° and 45°. Interns who have just arrived at the clinical department usually rely on their feelings and experience to judge the inclination angle of the needle during puncture. Therefore, the puncture angle of the needle is often too large or too small. If the inclination angle of the needle is too large, the end of the needle will easily puncture the muscle layer, making it difficult for the drug to be absorbed. If the inclination angle of the needle is too small, the end of the needle will easily stay on the surface of the skin, causing the patient to feel strong pain. Utility Model Content

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0028] like Figure 1-3 As shown, a needle position fixing device provided in this embodiment includes a syringe 1 having a needle 11 , a stop plate 2 , an adjustment component 3 and a connection component 4 .
[0029] See also Figure 1 and Figure 3 One end of the top of the support plate 2 is rotatably connected to an inclined plate 21, and the inclined plate 21 can adjust the inclination angle based on the rotation of the support plate 2. A slide bar 211 is provided on the side of the inclined plate 21 away from the support plate 2, and the slide bar 211 extends along the inclination direction of the inclined plate 21.
[0030] Preferably, a contact pad 24 is provided on the bottom side of the abutment plate 2. The contact pad 24 may be a rubber anti-skid pad or an adhesive pad to prevent the abutment plate 2 from sliding and shifting on the patient's skin surface.
[0031] Furthermore, a positioning ring 23 is provided at the end where the abutment plate 2 is connected to the inclined plate 21. When the abutment plate 2 is pressed against the patient's skin surface, the positioning ring 23 can circle the injection area, making it convenient for medical staff to determine the puncture point.
[0032] like Figure 2As shown, the adjustment component 3 includes a rotating cylinder 31 and an adjusting stud 32. One end of the rotating cylinder 31 is axially rotatably connected to a connecting block 33, and the other end is threadedly screwed with an adjusting stud 32. The outer ends of the connecting block 33 and the adjusting stud 32 are respectively rotatably connected to the side of the abutment plate 2 and the tilting plate 21 close to each other. By rotating the rotating cylinder 31, the adjusting stud 32 can be screwed out or screwed into the rotating cylinder 31 to change the overall length of the adjustment component 3, thereby adjusting the tilt angle of the tilting plate 21 based on the abutment plate 2.
[0033] See also Figure 1 and Figure 3 The connecting component 4 is slidably mounted on the slide bar 211 and is used to mount the syringe 1 .
[0034] During specific use, the syringe 1 is installed on the connecting component 4, and the rotating drum 31 is rotated to change the inclination angle of the inclined plate 21 based on the abutment plate 2, and the bottom of the abutment plate 2 is placed on the surface of the patient's skin, so that the needle 11 of the syringe 1 forms a suitable puncture angle with the patient's skin surface, and the syringe 1 is pushed to make the connecting component 4 slide on the slide bar 211 close to the patient's skin, and then the needle 11 will be smoothly penetrated into the patient's skin for injection of medicine.
[0035] The utility model utilizes the adjustment component 3 to form a support for the inclined plate 21. When the plate 2 is placed against the patient's skin, the inclined plate 21 can serve as a stable puncture platform for the connecting component 4 to carry the syringe 1 to slide on the slide bar 211 for puncture, which can prevent the medical staff from holding the syringe 1 in the air and shaking their hands, resulting in puncture position deviation or uncontrollable puncture angle. By rotating the rotating drum 31, the inclination angle of the inclined plate 21 based on the plate 2 can be changed as needed, providing a suitable puncture angle for the needle 11 and improving the injection success rate.
[0036] Specifically, the connecting assembly 4 includes a sliding block 41 and a ring sleeve 42. The sliding block 41 is slidably mounted on the slide bar 211, and the ring sleeve 42 is mounted on the sliding block 41. The inner diameter of the ring sleeve 42 is adapted to the diameter of the syringe 1, and a ring 421 for the needle 11 to pass through is provided at the lower port of the ring sleeve 42. When in use, one end of the needle 11 of the syringe 1 can be placed in the ring sleeve 42 and abutted against the ring 421. The needle 11 will pass through the ring 421, and the syringe 1 can be pushed to push the sliding block 41 toward the patient's skin surface for puncture.
[0037] Preferably, a transversely penetrating mounting groove 411 is provided on the top side of the sliding block 41, the mounting groove 411 is perpendicular to the sliding bar 211, and the mounting groove 411 is a special-shaped groove, such as Figure 3As shown, the mounting groove 411 can be a T-shaped groove, and the ring sleeve 42 has a plurality of models of different sizes, which can hold syringes of different sizes, and a mounting block 422 adapted to the mounting groove 411 is provided on one side of each ring sleeve 42. By sliding the mounting block 422 into or out of the mounting groove 411, a detachable connection between the ring sleeve 42 and the sliding block 41 can be achieved, so that a suitable ring sleeve 42 can be selected according to the size of the syringe used, and because the mounting groove 411 is perpendicular to the slide bar 211, the mounting block 422 will not fall out of the mounting groove 411 when the ring sleeve 42 is pushed along the direction of the slide bar 211.
[0038] like Figure 1 and Figure 3 As shown, in one embodiment, a slider 22 is slidably provided on one side edge of the inclined plate 21, and the sliding direction of the slider 22 is parallel to the slide bar 211. A locking stud 221 is threadedly screwed on the slider 22, and one end of the locking stud 221 can abut against the surface of the inclined plate 21. By tightening or loosening the locking stud 221, the slider 22 can be fixed or movable relative to the inclined plate 21. A baffle 222 is provided on the slider 22, and the baffle 222 is located above the path of the slide bar 211. By moving the slider 22, the position of the baffle 222 above the path of the slide bar 211 can be changed, so that the sliding block 41 is restricted to stay in this position when it moves close to the patient's skin, thereby changing the penetration depth of the needle 11 as needed.
