TECHNICAL FIELD
[0001] The utility model belongs to the field of medical apparatus and instruments, especially a raloxifene muscle injection positioning ruler. BACKGROUND
[0002] Raloxyfen is an antitumor drug, which belongs to a competitive estrogen receptor antagonist. It is mainly used for estrogen receptor positive local advanced or metastatic breast cancer which relapses after or during the treatment of anti-estrogen adjuvant therapy or disease progression in postmenopausal women (including natural menopause and artificial menopause). Recommended dose: 500mg (2 bottles) each time; injection method: intramuscular injection, 1 bottle on each side of the hip; frequency: once a month; treatment cycle: if the patient has good treatment effect, it is used continuously, and the period is at least half a year, and more than 2 years or more.
[0003] When raloxifene is injected, the injection site is generally the hip muscle, and the injection positioning adopts cross method or line method. The cross method is that a horizontal line is made from the top of the patient's hip split to the left or right, and a vertical bisector is selected at the highest point of the iliac spine, and the outer upper quarter (avoiding the inner corner area) is calculated as the injection site. The line method is that the line connecting the patient's anterior superior iliac spine and coccyx is taken, and the injection site is in the outer third range of the line. Because the drug is in the form of oil, the injection resistance is large, the patient's pain is obvious, and the drug solution is slowly absorbed. In addition, the breast cancer patients have a long treatment cycle, the injection positioning is not accurate, the same site is repeatedly injected, and the like, which can easily cause multiple indurations of the hip muscle, further hinder the absorption of the injected drug. In severe cases, it can cause the patient to have post-injection exudation, local skin infection, sinus formation and other adverse events, greatly affecting the patient's quality of life, and even more, the treatment scheme has to be changed because the patient cannot tolerate the discomfort of the hip induration, affecting the overall prognosis of the patient.

[0028] For example, Figures 1-5As shown, the utility model provides a kind of muscle injection positioning ruler of fulvestrant, comprising: a long fixed ruler 1, two short rulers 2, two arc pieces 3, the two short rulers 2 are located long fixed ruler 1 two sides respectively, with long fixed ruler 1 rotationally connected;Two arc pieces 3 symmetrically distribute long fixed ruler 1 two sides, each arc piece 3 is one side with long fixed ruler 1 fixed connection, the other side is with short ruler 2 fixed connection, and a plurality of positioning holes 32 are made on arc piece 3.The utility model is by rotating short ruler 2 drive arc piece 3 completely unfold, according to the highest point of iliac ridge and hip split vertex of patient human body to determine the position of fulvestrant muscle injection positioning ruler, and operator only needs to inject fulvestrant liquid in positioning hole 32 to complete operation, compared with cross method, line method and other modes, one-step, avoid injection site artificial search, simplify positioning step, save operation time, improve injection efficiency.
[0029] As Figures 1-2 Shown, the positioning hole 32 on each arc piece 3 is 12, and each injection is injected with one needle in left and right hips, i.e. when injecting in left hip, injecting from the positioning hole 32 on the left arc piece 3, and when injecting in right hip, injecting from the positioning hole 32 on the right arc piece 3.Each of the left arc piece 3 and the right arc piece 3 is provided with 12 positioning holes 32, and is marked with serial numbers 1-12, and each month, injection is performed in one positioning hole 32, so that repeated injection within one year can be completely avoided, the problem of inaccurate positioning by manual search is solved, adverse effects such as hip muscle induration, post-injection exudation, local skin infection and sinus formation caused by repeated injection are reduced, and thus, the injection pain of the patient is reduced, the treatment compliance and the life quality are improved.
[0030] As Figure 2 Shown, the inner side of the arc piece 3 is an arc-shaped notch 31, which can avoid the area where the sciatic nerve and its branches are located to prevent injection errors.When the sciatic nerve is in the hip, it passes under the piriform muscle and is located on the inner and lower side of the hip.During muscle injection, this area needs to be avoided, and the outer and upper side of the hip is selected for corresponding muscle injection, otherwise, if the sciatic nerve is damaged, the lower limbs will be numb and painful, and even muscle strength will be reduced. Figures 3-4 As Figures 3-4 Shown, the utility model is the state of fulvestrant muscle injection positioning ruler in folding, and the positioning ruler can be folded when not in use, saving space.The arc piece 3 is made of paper material, cloth, plastic or silicone material, which is convenient for folding and storing, the long fixed ruler and the short ruler are made of wood, plastic or other materials, and the arc piece 3 is pasted on the long fixed ruler 1 and the short ruler 2, which is fixed well, prolongs the service life and improves the reusability.
[0031] To better meet patient needs and facilitate operator operation, the size of the fulvestrant intramuscular injection positioning ruler of this utility model is set as follows: the length of the long fixed ruler 1 is 20-22cm, the length of the short adjusting ruler 2 is 10-11cm, the radius of the arc-shaped notch 31 is 3.0cm, and the diameter of the positioning hole 32 is 1.0cm.
[0032] The method of using this utility model is as follows:
[0033] like Figure 5 As shown, each injection requires one shot in each buttock. When injecting into the left buttock, the injection should be made through the positioning hole 32 on the left curved plate 3 (left buttock injection area), and when injecting into the right buttock, the injection should be made through the positioning hole 32 on the right curved plate 3 (right buttock injection area). Select one buttock, rotate the short ruler 2 until the curved plate 3 is fully extended, with the angle between the short ruler 2 and the long fixed ruler 1 at 90 degrees. Align the upper end of the long fixed ruler 1 with the highest point of the iliac crest of the patient's body, and align the short ruler 2 horizontally with the apex of the gluteal cleft of the patient's body. Inject fulvestrant solution into the positioning hole 32, and then repeat the procedure on the other buttock.
[0034] This invention allows for direct alignment of the positioning ruler with the highest point of the iliac crest and the apex of the gluteal cleft, enabling one-step determination of the injection site for fulvestrant injection. Compared to methods such as the cross method or the line method, this saves time spent manually locating the injection site, simplifies the procedure, and improves injection efficiency. Furthermore, by injecting fulvestrant within the positioning hole 32, it eliminates injection errors caused by unprofessional techniques or inaccurate manual positioning, preventing repeated injections and reducing the occurrence of gluteal muscle induration, post-injection effusion, local skin infection, and sinus tract formation. This, in turn, reduces patient discomfort and improves treatment adherence and quality of life.
