[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0019] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0021] See attached document Figure 1 This application provides a vastus lateralis muscle positioning ruler, including an upper positioning rod 1, a lower positioning rod 2, and a telescopic ruler 3. The upper positioning rod 1 and the lower positioning rod 2 are fixedly mounted at both ends of the telescopic ruler 3. The upper positioning rod 1 is flush with the hip joint during use, and the lower positioning rod 2 is flush with the knee joint. The distance between the upper positioning rod 1 and the lower positioning rod 2 and the telescopic ruler 3 is 10cm, ensuring that the two ends of the telescopic ruler 3 are 10cm from the knee joint and hip joint, respectively. The telescopic ruler 3 includes an upper frame 31 and a lower frame 32, which are slidably connected, allowing the telescopic ruler 3 to be adjusted to meet the positional requirements of the upper positioning rod 1 and the lower positioning rod 2. The inner width of the frame formed by the upper frame 31 and the lower frame 32 is 7.5cm.

[0022] As can be seen, when using the vastus lateralis positioning ruler, the lower positioning rod 2 is aligned with the knee joint and kept stationary. The upper positioning rod 1 is pulled to extend or retract the telescopic ruler 3, aligning the upper positioning rod 1 with the hip joint. The area enclosed by the telescopic ruler 3 is the vastus lateralis, thus guiding inexperienced operators to complete the injection.

[0023] Specifically:

[0024] In this embodiment, to achieve the telescopic adjustment function of the telescopic ruler 3, such as Figure 2 and Figure 3 As shown, both the upper ruler frame 31 and the lower ruler frame 32 are U-shaped structures, with their U-shaped openings facing each other. The lower ruler frame 32 has an axially arranged slot 320, and the slot 320 has a side groove 321. The upper ruler frame 31 is inserted into the slot 320, and the upper ruler frame 31 has a side block 310 that mates with the side groove 321. Therefore, the upper ruler frame 31 and the lower ruler frame 32 are slidably connected through the side groove 321, the slot 320, and the side block 310.

[0025] Of course, in order to lock the length after the telescopic ruler 3 has completed its telescopic positioning, as described above... Figure 2 As shown, the lower frame 32 has a threaded hole on its side, and a locking bolt 4 is installed in the threaded hole to press the upper frame 31 against the slide groove. It can be imagined that when locating the vastus lateralis muscle, the locking bolt is screwed outwards to disengage it from the upper frame 31, allowing the upper frame 31 and lower frame 32 to be stretched. Once the positions of the upper frame 31 and lower frame 32 are determined, the length of the telescopic ruler 3 can be fixed by screwing the locking bolt inwards.

[0026] In a preferred embodiment, in order to fix the positioning ruler to the human body during use, such as Figure 1 and Figure 2 As shown, the upper positioning rod 1 and the lower positioning rod 2 are fixed to the upper ruler frame 31 and the lower ruler frame 32 via a connecting rod 6. The connecting rod 6, which connects the lower positioning rod 2, is equipped with two restraint straps 5, connected by Velcro. It can be imagined that the positioning ruler can be secured to the thigh between the lower positioning rod 2 and the lower ruler frame 32 using the restraint straps 5, thus eliminating the need to hold the positioning ruler during injection, making it more convenient for the operator.

[0027] As can be seen from the above, the method of using the vastus lateralis muscle positioning ruler provided in this application embodiment is as follows:

[0028] The entire positioning ruler is placed on the outside of the thigh. The lower positioning rod 2 is roughly aligned with the knee joint, and the positioning ruler is fixed by binding the thigh with the restraint strap 5. Keep the lower positioning rod 2 still. After loosening the tightening bolt, pull the upper positioning rod 1 to roughly align with the hip joint. Then tighten the tightening bolt to lock the telescopic ruler 3, thereby locating the vastus lateralis muscle. The area enclosed by the telescopic ruler 3 is the vastus lateralis muscle.

[0029] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
