Description

Technical Field

[0001] The utility model relates to the technical field of teaching tools, in particular to a subcutaneous injection demonstration device. Background Art

[0002] When teaching nursing, a subcutaneous injection demonstration device is needed. The subcutaneous injection demonstration device is an educational tool designed to help medical students, nursing students, medical staff and patients learn and master the skills of subcutaneous injection. It usually includes a realistic skin model made of silicone. This model has a multi-layer structure and a high-quality substrate design to prevent needle damage. The design of the subcutaneous injection demonstration device allows trainees or patients to practice intravenous injections on their arms, thereby helping students to become familiar with and master injection techniques before actual operations. The subcutaneous injection demonstration device is not only designed to allow learners to practice fully before real operations to reduce errors and injuries in actual operations, but also helps learners master the correct needle insertion force and speed and avoid jitter during needle insertion through repeated practice, thereby improving work efficiency and quality. The common subcutaneous injection demonstration devices on the market will have liquid residue after multiple demonstrations during injection, and the liquid is easy to seep out, which requires laborious wiping and cleaning later. In addition, the subcutaneous injection demonstration device is easy to roll during operation, and the subcutaneous injection demonstration device is light, which can easily cause the subcutaneous injection demonstration device to slide when the needle is inserted.

The absorption component 104 is made of sponge material. After the liquid enters the slot 102, the absorption component 104 absorbs the liquid to prevent the liquid from seeping out and spreading. A through groove 105 is formed through the inside of the absorption component 104. The two ends of the through groove 105 are in a horn-shaped structure, so that when the external wind enters the through groove 105, the liquid absorbed by the absorption component 104 can be quickly volatilized by means of the wind; a bottom piece structure 2; the bottom piece structure 2 is located at the bottom of the device body 1. The bottom piece structure 2 supports the device body 1 through an outer plate 201 and a support structure 202, improving the stability of the device body 1 and facilitating the free rotation of the device body 1, preventing the device body 1 from rolling above the placement surface. An embedded plate structure 206 is installed at the bottom of the bottom piece structure 2 through the outer plate 201 and a bottom groove 205. Symmetrically arranged contact plates 208 are fixed at the bottom end of the embedded plate structure 206. The wedge-shaped contact plates 208 are made of anti-slip rubber material and are used for anti-slip contact with the placement surface, so that the device body 1 will not be displaced after encountering a thrust, improving the stability.

[0025] In the embodiments of the present disclosure, as Figure 3 With Figure 4 shown, positioning grooves 101 in a circular ring structure are respectively formed at both ends of the device body 1 for embedding the support structure 202, so that the device body 1 can freely rotate inside the connection groove 203. A slot 102 is formed through the inside of the device body 1 for inserting the absorption component 104. The absorption component 104 can be freely pulled out after being inserted into the slot 102. Inner grooves 103 for guiding are respectively formed on both sides of the slot 102 for inserting a positioning rod assembly 108 to position and install the absorption component 104. Two outer rod assemblies 106 are respectively fixed at both ends of the absorption component 104. The two outer rod assemblies 106 at the same end are symmetrically arranged, and the outer ends of the outer rod assemblies 106 are in an arc structure; a guide plate assembly 107 is fixed inside the two outer rod assemblies 106 at the same end. The wedge-shaped guide plate assembly 107 is located at the outer end of the through groove 105, so that after the wind passes through, the wind entering the through groove 105 can be controlled to flow. A positioning rod assembly 108 in a rectangular structure is formed at the outer ends of the absorption component 104 and the outer rod assemblies 106. The positioning rod assembly 108 is inserted into the inner groove 103 to drive the absorption component 104 to be positioned and installed.

[0026] In the embodiments of the present disclosure, as Figure 5 With Figure 6As shown, an outer plate 201 is fixedly installed at each end of the bottom part structure 2 to provide auxiliary support and improve stability. A support structure 202 is fixedly installed at the top end of the outer plate 201 to improve the support effect, and the top end of the support structure 202 is an arc-shaped structure. A connection groove 203 is formed inside the support structure 202, and the device body 1 is embedded and rotates inside the connection groove 203. The support structure 202 is rotatably connected to the positioning groove 101. A wedge-shaped clamping groove 204 is formed at the bottom side of the support structure 202 for clamping with the clamping block structure 207 to stably install and use the embedded plate structure 206. A bottom groove 205 is formed at the bottom of the support structure 202, and the embedded plate structure 206 and the contact plate 208 are embedded and installed inside the bottom groove 205 to position and install the embedded plate structure 206 and the contact plate 208. A clamping block structure 207 is fixedly installed at the top end of the embedded plate structure 206, and the clamping block structure 207 with a wedge-shaped inner side penetrates through the bottom groove 205 and is clamped and fixed with the clamping groove 204 to drive the embedded plate structure 206 to be stably fixed and used.

[0027] The working principle of this embodiment: When subcutaneous injection demonstration is required, the device body 1 and the bottom part structure 2 can be controlled to move together, and the bottom part structure 2 and the outer plate 201 can be conveniently placed, so that the support structure 202 and the outer plate 201 press the embedded plate structure 206 and the contact plate 208. The bottom of the contact plate 208 is in anti-slip contact with the ground to improve the fixing effect on the device body 1. Then, the device body 1 is controlled to rotate and adjusted for use, and the syringe and the needle are controlled for use. With the help of the device body 1, subcutaneous injection demonstration is carried out. During the demonstration, the injected liquid enters into the slot 102, and the absorption component 104 absorbs the liquid to avoid liquid diffusion and seepage. At the same time, when the external air circulates, the wind passes through the through groove 105 to volatilize the liquid absorbed by the absorption component 104. Due to the anti-slip fixation of the device body 1 by the contact plate 208, after the needle is inserted into the device body 1, the device body 1 will not displace.
