Description

Technical Field

[0001] This utility model relates to a subcutaneous injection positioning card, belonging to the technical field of medical devices. Background Technology

[0002] Trastuzumab / trastuzumab dual-target subcutaneous formulations are revolutionizing anti-HER2 therapy. The HannaH study showed that subcutaneous trastuzumab injection (H-SC) achieved a pCR rate comparable to intravenous injection (H-IV) in neoadjuvant therapy, with no new safety issues identified. Related research data indicates that subcutaneous injection offers the following advantages over intravenous injection: no need for additional infusion ports / catheters, simple and rapid administration, less trauma, reduced patient pain and discomfort, outpatient availability, easier access to care, potential for self-administration, shorter waiting times, improved patient experience, reduced patient workload, less burden on patients, increased patient compliance, and reduced working hours for pharmacy and nursing staff.

[0003] In existing techniques, subcutaneous injection of trastuzumab typically targets the lateral thigh, specifically the subcutaneous area corresponding to the vastus lateralis muscle. The injection method involves using the left thumb and forefinger, spaced 5-6 cm apart, to pinch the skin into a crease. The right hand holds the syringe and inserts the needle at a 30-degree angle at the highest point of the crease. The needle should be fully inserted subcutaneously, avoiding the muscle, and injected slowly over approximately 2-5 minutes. After administration, the needle is left in place for 10 seconds. Injection sites should be alternated between the left and right thighs, with each new injection site at least 2.5 cm away from the previous one. However, practical application has revealed the following issues with this subcutaneous trastuzumab injection method:

[0004] 1. Nursing staff are unable to quickly and accurately determine the site of the patient's last injection;

[0005] 2. The interval between two injections is difficult to control, and nurses often need to use a ruler to do so, which makes the operation quite troublesome;

[0006] 3. Nursing staff have difficulty accurately controlling the injection time;

[0007] 4. Nursing staff have difficulty selecting injection sites in a planned manner;

[0008] 5. The rotation of injection sites is not standardized and takes a long time. Utility Model Content

[0009] In order to solve the above-mentioned problems existing in the prior art, this utility model provides a subcutaneous injection positioning card.

[0010] The technical solution of this utility model is as follows:

[0011] A subcutaneous injection positioning card includes a card body, which is divided into an injection area and a positioning area. The injection area has multiple injection holes, and the positioning area is located at the center of the injection area. The positioning area has a through-hole structure, and the injection area is also provided with an injection date mark and a serial number mark.

[0012] The injection area is divided into a nine-square grid structure, with injection holes located at the center of each of the other grids, except for the central grid.

[0013] The positioning area is located in the center of the injection area at the grid position.

[0014] The injection date identifier and serial number identifier are provided in each cell of the injection area where an injection hole is provided.

[0015] The injection area is marked with scale markings at its four edges.

[0016] The card body is also divided into a text area, which is located above the injection area and contains the required information.

[0017] The bottom surface of the card body is provided with several anti-slip protrusions. The anti-slip protrusions are arranged in an arc shape and are provided around each injection hole. The anti-slip protrusions are arranged in a ring array around the injection hole with the center line of the injection hole as the array center.

[0018] In this card, magnetic blocks are embedded in the top and bottom of the text area. The magnetic blocks are symmetrically arranged on the top and bottom of the card, and the magnetic blocks at the top and bottom of the card are positioned to correspond to each other.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model divides the card body into an injection area and a positioning area. The injection area has an injection hole and is marked with an injection date and serial number. The positioning area is a through-hole structure. During use, nurses use the positioning area to locate the appropriate injection site on the patient. After positioning, the location corresponding to the injection hole is the subcutaneous injection site, facilitating injection. Simultaneously, by observing the time and serial number markings in the injection area, nurses can know which date and location should be injected, helping them accurately grasp the injection time, plan the selection of injection sites, and standardize the rotation of injection sites. This reduces the time required for nurses to select the appropriate injection area. Furthermore, by observing the injection date and serial number markings in the injection area and combining them with the actual date, nurses can quickly deduce the specific site of the patient's last injection, effectively helping them monitor the patient's injection status at any time. Compared to existing technologies, this model has the advantages of facilitating injection work and shortening the injection time.

[0021] 2. This utility model features scale markings on the injection area near its four edges. These markings facilitate nursing staff in measuring and comparing the injection location. Combined with the injection hole, this allows nursing staff to more easily control the interval between injections, thereby reducing the difficulty of injection operations.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1: Please refer to Figure 1This embodiment provides a subcutaneous injection positioning card, including a card body 1. The card body 1 is divided into an injection area 2, a positioning area 3, and a text area 4. The injection area 2 has multiple injection holes 5, each used for the insertion of a subcutaneous injection needle. The specific distribution of the injection holes 5 and the distance between adjacent injection holes 5 can be arranged according to actual conditions to meet the needs of subcutaneous injection positions in different situations. In this embodiment, taking the use of trastuzumab injection as an example, the injection area 2 is a square structure with a side length of 7.5cm, divided into a nine-square grid. Except for the central grid, injection holes 5 are located in the center of each of the other grids, and the distance between adjacent injection holes 5 is not less than 2.5cm. The positioning area 3 is located in the center of the injection area 2. The positioning area 3 has a through-hole structure, meaning the grid in the center of the injection area 2 is a continuous structure. The positioning area 3 is used by nursing staff to locate the appropriate injection area 2 region for the patient. The specific location of the appropriate injection area 2 region for the patient can be determined according to actual conditions. After locating the appropriate injection area 2 using the positioning area 3, the position corresponding to the injection hole 5 is the subcutaneous injection site. The nursing staff can complete the corresponding injection by inserting the subcutaneous injection needle into the injection hole 5 and inserting it under the patient's skin.

[0030] In this embodiment, each cell in the injection area 2, which has injection holes 5, is also equipped with an injection date marker 6 and a serial number marker 7. Nursing staff can rationally arrange the injection date markers 6 and serial number markers 7 in the injection area 2. By observing the date markers and serial number markers 7 in the injection area 2, nurses can determine which date and location should be injected, helping them accurately grasp the injection time, plan the injection site selection, and standardize the rotation of injection sites. This reduces the time required for nurses to select the appropriate injection area 2. Simultaneously, by observing the injection date markers 6 and serial number markers 7 in the injection area 2 and combining them with the actual date, nurses can quickly deduce the specific site of the patient's last injection, effectively helping them monitor the patient's injection status at any time. Taking the use of trastuzumab injection as an example, with a 21-day injection cycle, nurses mark the specific year, month, and day on the injection date marker 6 for each cell to help patients accurately grasp the injection time. Nurses can use the serial number 7 to divide the injection site into odd and even numbers in sequence. That is, the serial number 7 on the same injection positioning card is 1, 3, 5, ... or 2, 4, 6, ... Odd numbers correspond to the left side, such as the left leg, and even numbers correspond to the right side, such as the right leg. Patients can then use the serial number 7 and the injection date 6 to plan their injection site selection and rotate the injection sites in a standardized manner.

[0031] In this embodiment, scale markings 8 are provided on the injection area 2 near its four edges. The scale markings 8 make it convenient for nursing staff to measure and compare the injection position. Together with the injection hole 5, it makes it easier for nursing staff to control the interval between two injections, thereby reducing the difficulty of the injection operation.

[0032] In this embodiment, the text area 4 is located above the injection area 2. The text area 4 contains necessary information, such as relevant precautions and the location of the corresponding ward, to provide patients with appropriate guidance. The size of the text area 4 should not differ too much from that of the injection area 2. In this embodiment, the length of the text area 4 is the same as the side length of the injection area 2, which is 7.5cm, and the width of the text area 4 is 2.5cm.

[0033] Example 2: Please refer to Figures 2-4 This embodiment provides a subcutaneous injection positioning card, including all the structures in Embodiment 1. To facilitate patient use, the bottom surface of the card body 1 is further provided with several anti-slip protrusions 9. These anti-slip protrusions 9 are arc-shaped and are located around each injection hole 5, arranged in a circular array around the center line of the injection hole 5. When performing subcutaneous injections, the bottom surface of the card body 1 is in contact with the patient's skin. The anti-slip protrusions 9 increase the friction between the card body 1 and the patient's skin, preventing the card body 1 from slipping after positioning and requiring repositioning, thus facilitating use by the nursing staff.

[0034] In this embodiment, magnetic blocks 10 are embedded in the top and bottom of the text area 4 on the card body 1. The magnetic blocks 10 are symmetrically arranged on the top and bottom of the card body 1, and the positions of the magnetic blocks 10 at the top and bottom of the card body 1 are adapted to each other. This allows the magnetic block 10 at the top of the card body 1 to attract the magnetic block 10 at the bottom of the other card body 1 when two card bodies 1 are stacked together, thereby fixing the two card bodies 1 together. The magnetic blocks 10 facilitate the patient's overall collection and placement of the card bodies 1, preventing the loss of individual card bodies 1, and enabling nursing staff to easily monitor and control the patient's overall treatment process.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
