Description

Technical Field

[0001] The utility model relates to the field of injection auxiliary tools, in particular to a subcutaneous injection card suitable for multiple parts of children. Background Art

[0002] Subcutaneous injection is suitable for the treatment of a variety of patients, such as patients who need subcutaneous injection of long-term insulin, growth hormone and anticoagulants. It is a common treatment method in clinical practice. This injection method often requires patients to master and perform it themselves.

[0003] However, patients do not pay enough attention to the injection operation, which leads to irregular injection. For example, long-term insulin injection often causes adverse reactions such as redness, swelling, nodules, subcutaneous fat hyperplasia or atrophy at the injection site. One of the reasons is irregular replacement of injection sites. Studies have shown that the incidence of subcutaneous ecchymosis caused by subcutaneous injection of anticoagulants is 47%, and the incidence of nodules is 25%. Such adverse reactions such as subcutaneous bleeding and complications are important causes of anxiety, tension and other negative emotions in patients, and the occurrence and reduction of patients' medication compliance. The incidence of adverse reactions such as subcutaneous bleeding, ecchymosis and complications can be effectively reduced by alternating injection methods.

[0004] At present, there are various methods for rotating the subcutaneous injection area, and there are no specific operation instructions. During the injection process, patients and nurses are prone to repeat the injection area within a unit time, which increases the risk of adverse reactions on the skin in the injection area. Moreover, since the operation of site rotation is relatively complicated and the actual operation is difficult, most patients and nurses find it difficult to persist for a long time, especially for children (due to the age of children, their subcutaneous injection operations still mainly need to be performed by outsiders). The rotation injection operation is more difficult and the accuracy requirements for the injection operation are also higher. At the same time, the existing subcutaneous injection site rotation card is mainly for subcutaneous injections in the abdomen, and there are limitations on the use of subcutaneous injections in other locations. Utility Model Content

[0005] The utility model aims to provide a subcutaneous injection card suitable for multiple parts of children, which reduces the difficulty of rotating injection and improves the safety of subcutaneous injection.

[0006] The technical solution adopted by the utility model to solve the above problems is:

[0007] A subcutaneous injection card for children suitable for multiple sites, comprising:

[0008] A positioning ring, which is divided by a first dividing line to form a positioning area and a surrounding area arranged from the inside to the outside;

[0009] A first ring area, which is divided by a second dividing line into two semi-ring areas arranged symmetrically on the left and right, and the semi-ring areas are divided by a third dividing line into seven first divided areas;

[0010] The second ring area is divided by a fourth dividing line to form four second dividing areas which are arranged symmetrically with respect to the second dividing line;

[0011] The positioning ring, the first ring area and the second ring area are sequentially arranged from the inside to the outside, and a plurality of first through holes arranged at equal intervals are provided in the surrounding area, the first separation area and the second separation area.

[0012] As a further improvement of the above technical solution, the semi-ring area is covered with a first layer of sheet, the surrounding area and the second separation area are covered with a second layer of sheet and a third layer of sheet respectively, and the first layer of sheet, the second layer of sheet and the third layer of sheet are all provided with second through holes at positions relative to the first through hole, the diameter of the second through hole is larger than the diameter of the first through hole, and a removable fourth layer of sheet is provided on the second through hole, and the fourth layer of sheet covers the first through hole.

[0013] As a further improvement of the above technical solution, an annular marking layer is provided on the edge of the first through hole, and the color of the fourth layer is different from that of the marking layer.

[0014] As a further improvement of the above technical solution, the distance between adjacent first through holes is not less than 1 cm.

[0015] As a further improvement of the above technical solution, the positioning ring and the second ring area are both provided with four silicone gel pads arranged in a ring shape, and the positioning ring and the second ring area are both fixed on the skin by the silicone gel pads.

[0016] As a further improvement of the above technical solution, the diameter of the positioning ring is not less than 5 cm.

[0017] As a further improvement of the above technical solution, a cross positioning mark is provided at the center position of the positioning ring.

[0018] Compared with the prior art, the utility model has the following advantages and effects:

[0019] (1) The utility model uses the positioning ring, the first ring area and the second ring area in combination, so that the injection card can be used to meet the positioning requirements of different subcutaneous injection sites by using the first partition area alone or in combination with the second partition area, thereby improving the flexibility of the injection card and being applicable to subcutaneous injections in the main parts of children (i.e., abdomen, legs, buttocks and arms) and reducing the difficulty of subcutaneous injection operations.

[0020] (2) The utility model realizes quadrant division of the subcutaneous injection area through the semi-annular area and the second partition area, so that the user can clearly understand the injection position range in the subcutaneous injection area within the injection cycle, and combined with the first partition area, the second partition area and the first through hole arranged thereon, the injection position of each subcutaneous injection within the injection cycle can be further divided and located according to the injection position range in the quadrant of the injection cycle, which reduces the difficulty of rotating injections when performing subcutaneous injections on children, thereby reducing the occurrence of repeated injection positions and improving the safety of subcutaneous injections.

[0021] (3) The utility model provides a surrounding area on the positioning ring and a first through hole on the surrounding area, so that when only the first ring area of ​​the injection card is used alone, the surrounding area can be used in conjunction with the first ring area to improve the injection positioning area, thereby ensuring the use effect of the injection card.

DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0028] See also Figure 1-Figure 4The present embodiment is a subcutaneous injection card suitable for multiple parts of a child, comprising a positioning ring 1, a first ring area 2 and a second ring area 3, wherein the positioning ring 1, the first ring area 2 and the second ring area 3 are sequentially arranged from the inside to the outside, the positioning ring 1 is divided by a first dividing line 41 to form a positioning area 11 and a surrounding area 12 arranged from the inside to the outside, the first ring area 2 is divided by a second dividing line 42 to form two semi-ring areas 21 arranged symmetrically on the left and right, the semi-ring areas 21 are divided by a third dividing line 43 to form seven first dividing areas 22, the second ring area 3 is divided by a fourth dividing line 44 to form four second dividing areas 31 arranged symmetrically on the left and right relative to the second dividing line 42, and a plurality of first through holes 5 arranged at equal intervals are provided in the surrounding area 12, the first dividing area 22 and the second dividing area 31.

[0029] When in use, place the injection card on the area to be injected and make the center point of the positioning ring 1 be located at the center of the area to be injected. Then adjust the placement angle of the injection card according to the body part where the area to be injected is located.

[0030] When the body part where the injection area is located is the abdomen (about 1 cm above the pubic symphysis, about 1 cm below the lowest costal margin, and the bilateral abdomen 2.5 cm around the navel), the injection card is placed horizontally so that the two half-ring areas 21 are arranged left and right, and when used, only the first ring area 2 and the second ring area 3 are used in combination;

[0031] When the body part to be injected is the buttocks (the upper outer side of both buttocks), the injection card is placed horizontally so that the two half-ring areas 21 are arranged left and right, and when used, the first ring area 2 and the surrounding area 12 are mainly used in combination and supplemented by the area of ​​the second ring area 3 close to the first ring area 2;

[0032] When the body part to be injected is the arm (the middle 1 / 3 of the outer side of the upper arm on both sides) and the leg (the upper 1 / 3 of the anterior and lateral side of the thigh on both sides), the injection card is placed vertically so that the two semi-ring areas 21 are arranged up and down, and when used, the first ring area 2 and the surrounding area 12 are mainly used in combination and supplemented by the area on the second ring area 3 close to the first ring area 2.

[0033] In this embodiment, the distance between adjacent first through holes 5 is not less than 1 cm, which reduces the impact between two subsequent subcutaneous injections, thereby ensuring the absorption of the drug.

[0034] In this embodiment, the diameter of the positioning ring 1 is not less than 5 cm, and when the injection card is used for abdominal injection, it can prevent the user from injecting in the area within 2.5 cm around the navel.

[0035] See also Figure 2The positioning ring 1 and the second ring area 3 are both provided with four silicone gel pads 7 arranged in a ring shape. The positioning ring 1 and the second ring area 3 are both fixed on the skin through the silicone gel pads 7, so that the injection card can be fixed on the injection area for use, thereby ensuring the accuracy of the injection position and the convenience of the injection operation. At the same time, since the silicone gel pads 7 can be reused (currently silicone gel pads have been used on scar patches, after the scar patch is used, the peeling paper torn off before use is re-covered on the silicone gel pad for the next use), it ensures that the injection card is adhered to the skin for multiple fixed uses, which improves the convenience of using the injection card.

[0036] See also Figure 2 , Figure 3 A cross positioning mark 6 is provided at the center of the positioning ring 1, which improves the accuracy of the user placing the injection card on the corresponding injection area.

[0037] See also Figure 1 , Figure 3 The semi-annular area 21 is covered with a first layer of sheet 81, and the surrounding area 12 and the second separation area 31 are respectively covered with a second layer of sheet 82 and a third layer of sheet 83. The first layer of sheet 81, the second layer of sheet 82 and the third layer of sheet 83 are all provided with a second through hole 84 at a position relative to the first through hole 5. The diameter of the second through hole 84 is greater than the diameter of the first through hole 5. A removable fourth layer of sheet 85 is provided on the second through hole 84, and the fourth layer of sheet 85 covers the first through hole 5, thereby reducing the visual impact of the dense arrangement of the first through holes 5 on the injection operation and realizing the distinction between unused and used first through holes 5.

[0038] See also Figure 4 , an annular marking layer 86 is provided on the edge of the first through hole 5, and the color of the fourth layer 85 is different from that of the marking layer 86 (i.e., the fourth layer 85 is green, indicating that the through hole is unused; the marking layer 86 is red, indicating that the through hole is used). When in use, the fourth layer 85 is torn off to expose the marking layer 86, so that the use status of the through hole can be visualized, thereby reducing the situation where the injection position is repeated when two subcutaneous injections are positioned by the same through hole.

[0039] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
