Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of medical devices, and in particular to a rotating position indicator cuff for desensitization treatment. Background Art

[0002] Allergic diseases are one of the common chronic diseases. Their incidence rate is increasing year by year around the world and has become a global health problem. Such diseases include allergic asthma, allergic rhinitis, etc., which often recur. Patients usually need long-term treatment with antihistamines, bronchodilators, hormones and other drugs. Some patients will have acute attacks and clinical symptoms such as severe anaphylactic shock, laryngeal edema, and dyspnea, and a few may even be life-threatening.

[0003] The above-mentioned drug treatments are all symptomatic treatments. The adverse reactions caused by long-term medication and the uncertainty of the severity of the disease have seriously affected the quality of life of patients. Actively finding allergens and avoiding them is the key to relieving symptoms. However, for those allergens that cannot be avoided, specific desensitization therapy is currently an effective means of treating such diseases. Specific desensitization therapy is the only known method that can change the immune type of patients with allergic diseases to allergens and may cure allergic diseases.

[0004] Atopic desensitization therapy is a causal treatment for allergic diseases induced by dust mites, pollen, animal dander, etc., which are mainly mediated by IgE. It has been recommended as a first-line treatment option by many guidelines. It includes subcutaneous desensitization therapy and sublingual immunotherapy. Among them, subcutaneous desensitization therapy is divided into conventional desensitization therapy and accelerated desensitization therapy according to the different injection frequencies in the dose accumulation stage. Accelerated desensitization therapy includes cluster desensitization therapy and impact desensitization therapy. The dose accumulation time of impact immunotherapy is the shortest, which is shortened from 4 months of conventional immunotherapy to less than 1 week. It is believed that it can increase patient compliance and reduce the dropout rate. Due to the rapid increase in the dose of allergens, its safety, especially the occurrence and avoidance of systemic adverse reactions, is a key issue that needs special attention in clinical practice. Due to multiple injections in a short period of time, if the injection is in the same site, the spacing is improper or the injection method is incorrect, it will cause local adverse reactions such as nodules and redness at the injection site, thereby affecting the effect of desensitization therapy.

[0005] The hospital implements a three-shift system. It is difficult for nurses to effectively hand over the rotation of injection sites for each desensitization treatment patient, and it is also difficult for the patients themselves to accurately describe the specific injection site each time. Due to insufficient injection spacing, delayed adverse reactions at the injection site are difficult to identify. Therefore, it is inevitable that the same injection site will be repeatedly injected or the injection site spacing will be inappropriate. Therefore, how to accurately locate and reasonably rotate the injection site for desensitization treatment and reduce the occurrence of subcutaneous nodules and local redness has become an urgent problem to be solved. Summary of the invention

[0006] To this end, an embodiment of the present invention provides a rotation site indication cuff for desensitization treatment. Through specific structural designs, such as setting eight through holes arranged in a regular octagon layout and the design of strip members related to the positions of the through holes, the present invention can provide clear indication for site rotation during desensitization treatment, improve the treatment effect and patient comfort, and has good clinical promotion value.

[0007] To achieve the above object, the embodiment of the present invention provides the following technical solutions:

[0008] A rotation site indication cuff for desensitization treatment, comprising a cuff body, a first strip member and a second strip member. The cuff body is provided with eight through holes arranged in a regular octagon layout. The first strip member and the second strip member are respectively located at the outer edges of the bottom and top of the cuff body, and both coincide with the vertical axis of symmetry of the regular octagon. The distance between the bottom edge of the first strip member and the center line connecting two adjacent through holes at the bottom in the vertical direction is 10 - 13 cm.

[0009] In some preferred embodiments, the distance between the centers of two adjacent through holes is 2 - 4 cm.

[0010] In some preferred embodiments, the through holes are circular with a diameter of 0.8 - 1.2 cm.

[0011] In some preferred embodiments, the cuff body is provided with digital identifiers, and each digital identifier is respectively adjacent to the edge of the corresponding through hole.

[0012] In some preferred embodiments, the distance between the top edge of the second strip member and the center line connecting two adjacent through holes at the top in the vertical direction is 15 - 20 cm.

[0013] In some preferred embodiments, the indication cuff is made of soft transparent plastic material. The soft transparent plastic material has good flexibility and transparency, which can improve patient comfort.

[0014] Considering the differences in upper arm circumference and length among patients of different ages, the present invention provides two rotation site indication cuffs with different sizes to adapt to different arm circumferences.

[0015] In some specific embodiments, the distance between the centers of two adjacent through holes is 2 cm, the distance between the bottom edge of the first strip member and the center line connecting two adjacent through holes at the bottom in the vertical direction is 10 cm, and the distance between the top edge of the second strip member and the center line connecting two adjacent through holes at the top in the vertical direction is 15 cm. This rotation site indication cuff is suitable for desensitization treatment patients with an arm circumference ≤ 30 cm.

[0016] In some specific embodiments, the distance between the centers of two adjacent through-holes is 4 cm. The distance between the bottom edge of the first strip-shaped member and the line connecting the centers of two adjacent through-holes at the bottom in the vertical direction is 13 cm. The distance between the top edge of the second strip-shaped member and the line connecting the centers of two adjacent through-holes at the top in the vertical direction is 20 cm. This rotation-site indicating cuff is suitable for desensitization treatment patients with an arm circumference > 30 cm.

[0017] The embodiments of the present invention have the following advantages:

[0018] The rotation-site indicating cuff of the present invention is exquisitely designed. During the actual operation, the nurse only needs to accurately position the cuff on the corresponding part of the patient and inject according to the corresponding part clearly marked with numbers on the cuff. This cuff can accurately ensure that the injection points do not repeat, and the injection spacing is reasonable, effectively avoiding adverse reactions such as local induration and flushing caused by improper injection positions, improving the treatment effect and patient comfort, and providing a reliable guide for the rotation of injection sites for various desensitization treatments. In addition, its manufacturing process is simple, using common and inexpensive materials, with low production costs, and has great clinical promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] Embodiment 1

[0025] This embodiment provides a rotation site indication cuff for desensitization treatment patients with an upper arm circumference ≤ 30 cm. Refer to Figure 1 , which includes a cuff body 10, a first strip member 20, a second strip member 30, a through hole 40, and a digital identifier 50.

[0026] Specifically, the cuff body 10 is a circular structure with a radius of about 5 cm. There are eight through holes 40 on the cuff body, and the through holes are circular with a radius of 1 cm. These eight through holes are arranged in a regular octagon layout, and the distance between the centers of adjacent two through holes is 2 cm. The digital identifier 50 is adjacent to the edge of the through hole and is sequentially marked as: "1", "4", "7", "2", "5", "8", "3", "6".

[0027] The first strip member 20 and the second strip member 30 are respectively located at the outer edges of the bottom and top of the cuff body, and coincide with the vertical axis of symmetry of the regular octagon formed by the eight through holes. The distance between the bottom edge of the first strip member 20 and the center connection line of the through holes marked with "8" and "5" in the vertical direction is 10 cm, and the distance between the top edge of the second strip member 30 and the center connection line of the through holes marked with "1" and "4" in the vertical direction is 15 cm.

[0028] The manufacturing method of the rotation site indication cuff in this embodiment is as follows:

[0029] ① Material preparation and preliminary forming: Select a piece of soft and transparent plastic material and accurately cut it according to the designed dimensions. During the cutting process, it is necessary to ensure that a circular (or nearly circular) cuff body is obtained, and at the same time, strip members are integrally formed at the outer edges of the top and bottom of the cuff body, so that the cuff body and the strip members form a complete structure.

[0030] ② Through hole and digital identifier setting: On the formed cuff body, accurately cut off eight round holes in a specific order, so that these eight round holes are arranged in a regular octagon layout. The diameter of each round hole is set to 1 cm, and the distance between the centers of adjacent two round holes is 2 cm. After the round hole cutting is completed, sequentially mark the digital identifier "1 - 8" next to each round hole (for the marking order, see Figure 1), these digital markings are used to clarify the injection sequence of the first to eighth injections, and the site indicated by the circular hole is the injection site. It should be noted that the two strip-shaped parts coincide with the vertical symmetry axes of the regular octagon, so as to ensure the positioning accuracy of the indicator cuff during use.

[0031] ③ Key size setting: To ensure the functionality and accuracy of the indicator cuff, specific dimensions must be strictly controlled. Among them, the distance between the line connecting the circular holes corresponding to the digital logos "5" and "8" and the bottom edge of the first belt-shaped component should be 10cm; the distance between the line connecting the circular holes corresponding to the digital logos "1" and "4" and the top edge of the second belt-shaped component is 15cm. By accurately setting these dimensions, medical staff can effectively assist in accurately determining the injection site during the desensitization treatment injection process, thereby improving the safety and effectiveness of the treatment.

[0032] Example 2

[0033] The present embodiment provides a rotation position indicator cuff for desensitization treatment patients with an arm circumference greater than 30 cm. The difference between the present embodiment and embodiment 1 is that the cuff body 10 is a circular structure with a radius of about 7 cm, the distance between the centers of two adjacent through holes is 4 cm, the distance between the bottom edge of the first band-like component 20 and the center line of the through holes marked with numbers "8" and "5" in the vertical direction is 13 cm, and the distance between the top edge of the second band-like component 30 and the center line of the through holes marked with numbers "1" and "4" in the vertical direction is 20 cm.

[0034] Example 3

[0035] Application of rotating position indicator cuff in desensitization therapy

[0036] Injection positioning operation: the patient's upper arm is in a vertical and relaxed state, the bottom edge of the first belt-like component 20 is positioned at the olecranon bony landmark of the upper arm, the second belt-like component 30 is positioned at the acromion bony landmark of the upper arm, and the edge of the second belt-like component 30 is gently pulled to make the first belt-like component and the second belt-like component both in a straight state. At this time, the eight through holes in a regular octagonal layout are located on the line connecting the olecranon bony landmark and the acromion bony landmark of the upper arm, and the distance between the line connecting the two through holes at the bottom and the olecranon bony landmark in the vertical direction is fixed at 10 cm (arm circumference ≤ 30 cm) or 13 cm (arm circumference > 30 cm).

[0037] Injection and recording: Rotate the injections in the order of the through-holes corresponding to the digital identifiers "1", "2", "3", "4", "5", "6", "7", and "8". The distance between the centers of two adjacent through-holes is 2 - 4 cm. When the injections are rotated in the above order, the distance between two puncture points is 4 - 8 cm. Since a induration at the puncture site exceeding 4 cm is a serious adverse reaction, the designed distance of 4 - 8 cm in the present invention is to observe and avoid the adverse reaction of skin delayed induration from extending to adjacent puncture points.

[0038] After the nurse completes the injection, record the digital identifier of the cuff corresponding to this injection in the patient's medical record, so as to accurately rotate the injection site during the next treatment. For example, record that this injection is at the position corresponding to the digital identifier "3", and select the position corresponding to the digital identifier "4" for injection next time, effectively avoiding repeated injections at the same site.

[0039] Before the next injection, the rotation site indicating cuff is positioned in the same manner as above, that is, ensuring that the eight through-holes in the shape of a regular octagon are on the line connecting the olecranon bone landmark and the acromion bone landmark of the upper arm, and the distance of the line from the olecranon bone landmark in the vertical direction is fixed at 10 cm (arm circumference ≤ 30 cm) or 13 cm (arm circumference > 30 cm). By using the above method, the accurate position of the injection site can be confirmed, achieving precise positioning of the injection site, and minimizing the occurrence of subcutaneous induration and local flushing during the impact desensitization treatment positioning and rotation injection, effectively improving the treatment effect and patient comfort.

[0040] Our institution selected 105 cases of patients undergoing impact desensitization treatment from 2022 to 2024 and operated according to the injection method specified in the present invention. The results showed that no serious local skin adverse reactions occurred in all patients, which effectively ensured the safety of the patients and the smooth progress of the impact desensitization treatment.

[0041] Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
