Description

Technical Field

[0001] The utility model relates to the technical field of injection anticoagulant positioning rulers, in particular to an abdominal subcutaneous injection positioning ruler. Background Technique

[0002] At present, when hospitals give subcutaneous injections of anticoagulants to patients, nurses often infer the time and position of the previous injection by observing the needle hole conditions or bruise conditions on the patient's abdomen. However, this judgment method is prone to errors and is likely to cause repeated area injections, bringing potential medical and nursing safety hazards to patients and causing subcutaneous bleeding. There are also individual hospitals that originally wanted to use the existing insulin positioning injection patch to complete subcutaneous injection of anticoagulants.

[0003] In a kind of insulin injection site positioning plate with the publication number CN2693253Y, the injection of insulin is different from that of anticoagulants. For insulin, it only requires that the distance between the injection areas of the previous and next injections is more than 2 cm. However, the best injection method for anticoagulants is to divide the effective injection site into four quadrants and rotate them regularly. The distance between adjacent injection points must be separated by a distance greater than 2 cm, which can effectively avoid subcutaneous bleeding. Therefore, the existing insulin positioning injection patch cannot be used to inject anticoagulants. Moreover, the existing insulin positioning injection patch is not conducive to positioning and fitting on the patient's abdomen and needs to be assisted by a tie for fixation, which is inconvenient to operate.

[0004] Therefore, we propose an abdominal subcutaneous injection positioning ruler. Content of the Utility Model

[0005] The purpose of the utility model is to provide an abdominal subcutaneous injection positioning ruler to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an abdominal subcutaneous injection positioning ruler, including a first positioning ruler and a second positioning ruler vertically assembled. Corresponding central holes are opened at the centers of the first positioning ruler and the second positioning ruler. A limiting ring is integrally formed on the first positioning ruler inside the central hole, and the second positioning ruler is sleeved and assembled on the limiting ring by using the central hole;

[0007] Transverse positioning holes are uniformly arranged along the length direction on the first positioning ruler. Longitudinal positioning holes are uniformly arranged along the length direction on the second positioning ruler, and the distance between adjacent two groups of longitudinal positioning holes is the same as the distance between adjacent two groups of transverse positioning holes. Five groups of angular limiting grooves are opened on the surface of the first positioning ruler, and all five groups of angular limiting grooves are circular holes. The centers of the circular holes are all located on a circle concentric with the central hole, and the five groups of angular limiting grooves are respectively arranged at the positions of 30°, 60°, 90°, 120° and 150° at the center of the central hole, and the angular limiting grooves are adapted to arc-shaped limiting blocks.

[0008] Preferably, a first collar is slidably assembled at the left end of the first positioning ruler, and a second collar is slidably assembled at the right end of the first positioning ruler. The first collar and the second collar are of the same size, and transverse positioning holes are formed on their surfaces.

[0009] Preferably, first sliding grooves are formed on the upper and lower side walls of the first positioning ruler, and first sliding blocks adapted to the first sliding grooves are integrally formed on the inner side walls of the first collar and the second collar.

[0010] Preferably, a third collar is slidably assembled at the upper end of the second positioning ruler, and a fourth collar is slidably assembled at the lower end of the second positioning ruler. The third collar and the fourth collar are of the same size, and longitudinal positioning holes are formed on their surfaces.

[0011] Preferably, second sliding grooves are formed on the upper and lower side walls of the first positioning ruler, and second sliding blocks adapted to the second sliding grooves are integrally formed on the inner side walls of the first collar and the second collar.

[0012] Preferably, the arc-shaped limiting block is arranged directly above the central hole, and the position of the arc-shaped limiting block corresponds to the angle limiting groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The structure of the present utility model is reasonably designed. When the central hole coincides with the position of the human navel, the transverse positioning holes and the longitudinal positioning holes are found according to the injection requirements, and the injection position can be quickly changed according to the injection needs in the morning, noon and evening. At the same time, if the first positioning ruler remains horizontal and stationary, the second positioning ruler can rotate relative to the first positioning ruler, and the limiting ring can limit the second positioning ruler, so that the second positioning ruler can only rotate relative to the first positioning ruler around the central hole, which can ensure the fixity of the positioning ruler relative to the position of the human navel.

[0015] 2. When the second positioning ruler is rotated in the present utility model, when the arc-shaped limiting block does not correspond to the angle limiting groove, the second positioning ruler and the first positioning ruler cannot be limited at this time. Only when the arc-shaped limiting block corresponds to the angle limiting groove, the arc-shaped limiting block is limited and installed inside the angle limiting groove, and the second positioning ruler and the first positioning ruler are limited at this time, and self-deflection will not occur. Moreover, the angle limiting grooves are respectively arranged at the positions of 30°, 60°, 90°, 120° and 150° at the center of the circle of the central hole. Therefore, the deflection angle of the second positioning ruler relative to the first positioning ruler can be adjusted according to the injection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: an abdominal subcutaneous injection positioning ruler, including a first positioning ruler 1 and a second positioning ruler 6 vertically assembled. Central holes 2 corresponding to each other are opened at the centers of the first positioning ruler 1 and the second positioning ruler 6. A limiting ring is integrally formed on the first positioning ruler 1 inside the central hole 2. The second positioning ruler 6 is sleeved and assembled on the limiting ring by using the central hole 2. In this way, based on the vertically assembled first positioning ruler 1 and second positioning ruler 6, the human abdomen can be divided into four quadrants. At the same time, the central hole 2 can coincide with the human navel position to achieve positioning, which is more convenient for positioning and improves the operation convenience.

[0023] The first positioning ruler 1 is evenly provided with transverse positioning holes 5 along the length direction, and the second positioning ruler 6 is evenly provided with longitudinal positioning holes 9 along the length direction. The distance between adjacent two groups of longitudinal positioning holes 9 is the same as the distance between adjacent two groups of transverse positioning holes 5. Five groups of angular limiting grooves 11 are formed on the surface of the first positioning ruler 1, and the five groups of angular limiting grooves 11 are all circular holes, and the centers of the circular holes all fall on a circle concentric with the central hole 2. The five groups of angular limiting grooves 11 are respectively arranged at the positions of 30°, 60°, 90°, 120° and 150° at the center of the central hole 2. The angular limiting grooves 11 are adapted to the arc-shaped limiting blocks 10. During actual use, when the central hole 2 coincides with the position of the human navel, the transverse positioning holes 5 and the longitudinal positioning holes 9 are found according to the injection requirements, and the injection position can be quickly changed according to the injection needs in the morning, noon and evening. At the same time, if the first positioning ruler 1 remains horizontal and stationary, the second positioning ruler 6 can rotate relative to the first positioning ruler 1, and the limiting ring can limit the second positioning ruler 6, so that the second positioning ruler 6 can only rotate relative to the first positioning ruler 1 around the central hole 2, which can ensure the fixity of the positioning ruler relative to the position of the human navel.

[0024] The arc-shaped limiting block 10 matches the angular limiting groove 11. Therefore, when the second positioning ruler 6 is rotated, when the arc-shaped limiting block 10 does not correspond to the angular limiting groove 11, the second positioning ruler 6 and the first positioning ruler 1 cannot be limited at this time. Only when the arc-shaped limiting block 10 corresponds to the angular limiting groove 11, the arc-shaped limiting block 10 is limited and installed inside the angular limiting groove 11. At this time, the second positioning ruler 6 and the first positioning ruler 1 are limited, and the situation of self-deflection will not occur. And the angular limiting grooves 11 are respectively arranged at the positions of 30°, 60°, 90°, 120° and 150° at the center of the central hole 2. Therefore, the deflection angle of the second positioning ruler 6 relative to the first positioning ruler 1 can be adjusted according to the injection requirements.

[0025] A first sleeve ring 3 is slidably assembled at the left end of the first positioning ruler 1, and a second sleeve ring 4 is slidably assembled at the right end of the first positioning ruler 1. The first sleeve ring 3 and the second sleeve ring 4 have the same size, and transverse positioning holes 5 are formed on the surfaces. First sliding grooves are formed on the upper and lower side walls of the first positioning ruler 1. First sliding blocks adapted to the first sliding grooves are integrally formed on the inner side walls of the first sleeve ring 3 and the second sleeve ring 4, which is convenient for the first sleeve ring 3 and the second sleeve ring 4 to move on the first positioning ruler 1, can divide more injection areas, and improve the injection convenience.

[0026] A third collar 7 is slidably assembled at the upper end of the second positioning ruler 6, and a fourth collar 8 is slidably assembled at the lower end of the second positioning ruler 6. The third collar 7 and the fourth collar 8 are of the same size, and longitudinal positioning holes 9 are provided on their surfaces. Second chutes are provided on the upper and lower side walls of the first positioning ruler 1, and second sliders adapted to the second chutes are integrally formed on the inner side walls of the first collar 3 and the second collar 4, which facilitates the movement of the third collar 7 and the fourth collar 8 on the second positioning ruler 6, can divide more injection areas, and improve the injection convenience.

[0027] An arc-shaped limiting block 10 is arranged directly above the central hole 2, and the position and angle of the arc-shaped limiting block 10 correspond to the angle limiting groove 11. When the arc-shaped limiting block 10 corresponds to the angle limiting groove 11, it is convenient to realize the limiting installation between the first positioning ruler 1 and the second positioning ruler 6, and prevent the positioning ruler from self-deflecting.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
