Description

Technical Field

[0001] This utility model relates to the field of medical education and training equipment technology, and in particular to a highly realistic simulation instrument for intravenous infusion and blood collection. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, materials or other articles used alone or in combination on the human body, including the necessary software; their effects on the human body surface and inside the body are not obtained through pharmacological, immunological or metabolic means, but these means may be involved and play a certain auxiliary role.

[0003] Medical equipment can be divided into medical education and training equipment and practical application tools.

[0004] In the medical education and training process, educators need to teach medical students how to perform intravenous infusions or blood draws. However, both intravenous infusions and blood draws need to be performed on human bodies, which limits the educational scope and is not conducive to the use of medical education. Utility Model Content

[0005] Purpose of the invention: The purpose of this utility model is to provide a highly realistic simulation instrument for intravenous infusion and blood collection, thereby solving the problems mentioned in the background art.

[0006] Technical solution: A highly realistic simulation of intravenous infusion and blood collection training instrument, comprising a highly realistic arm mold, wherein a threaded groove is formed on the upper part of the interior of the highly realistic arm mold, and a groove is formed on the interior of the highly realistic arm mold below the threaded groove, and the groove is connected to the threaded groove; wherein a plurality of simulated blood vessels are arranged on the interior of the highly realistic arm mold near the lower part of the groove, and each simulated blood vessel is filled with liquid.

[0007] A threaded cap is embedded in the inner wall of the threaded groove, and the threaded cap is threadedly connected to the threaded groove. A round cap is provided on the upper surface of the threaded cap, and the round cap is glued and fixed to the threaded cap. A semi-circular piece is provided in the middle of the upper surface of the round cap, and the semi-circular piece is fixedly connected to the round cap. The highly realistic arm mold includes an epidermis, a dermis, and subcutaneous tissue. The dermis is provided on one side of the epidermis, and the dermis is glued and fixed to the epidermis. The subcutaneous tissue is provided on the surface of the dermis, and the subcutaneous tissue is fixedly connected to the dermis.

[0008] Furthermore, the liquid is red.

[0009] Furthermore, the diameter of the round cap is larger than the diameter of the threaded cap.

[0010] Furthermore, several of the simulated blood vessels are interconnected, and the simulated blood vessels are connected to the groove.

[0011] Furthermore, the semicircular piece, the circular cap, and the threaded cap are all made of PVC plastic.

[0012] Beneficial effects:

[0013] In this invention, medical students can practice using the device without the need for a real human arm, making it highly practical. During practice, medical students can follow the same steps as when practicing on a human body. When performing a proper intravenous infusion or blood draw, the fluid in the simulated blood vessel flows into the needle. Medical students can practice repeatedly, ensuring high safety and effectively improving the professional skills of nursing staff.

[0014] In this invention, when the semicircular piece is held and rotated, the threaded cover can be removed from the threaded groove. Medical staff can pour liquid into the groove, and the liquid flows into the simulated blood vessel. The liquid acts as blood, and during practice, it can be seen whether the simulation is correct and the puncture is accurate. Attached Figure Description

[0019] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] According to the appendix Figure 1-3 A highly realistic simulation of intravenous infusion and blood collection training instrument is provided, including a highly realistic arm mold 1. A threaded groove 5 is opened on the upper part of the interior of the highly realistic arm mold 1. A groove 6 is opened on the interior of the highly realistic arm mold 1 and below the threaded groove 5, and the groove 6 is connected to the threaded groove 5. Several simulated blood vessels 7 are arranged on the interior of the highly realistic arm mold 1 near the lower part of the groove 6, and each simulated blood vessel 7 is filled with liquid 11.

[0022] A threaded cap 4 is embedded in the inner wall of the threaded groove 5. The threaded cap 4 is threadedly connected to the threaded groove 5. A round cap 3 is provided on the upper surface of the threaded cap 4. The round cap 3 is glued and fixed to the threaded cap 4. A semi-circular piece 2 is provided in the middle of the upper surface of the round cap 3. The semi-circular piece 2 is fixedly connected to the round cap 3. The high-simulation arm mold 1 includes an epidermal layer 8, a dermal layer 9 and a subcutaneous tissue 10. A dermal layer 9 is provided on one side of the epidermal layer 8. The dermal layer 9 is glued and fixed to the epidermal layer 8. A subcutaneous tissue 10 is provided on the surface of the dermal layer 9. The subcutaneous tissue 10 is fixedly connected to the dermal layer 9.

[0023] In this embodiment, liquid 11 is red and acts as blood.

[0024] In this embodiment, the diameter of the round cover 3 is larger than the diameter of the threaded cover 4, and the round cover 3 is positioned above the threaded cover 4.

[0025] In this embodiment, several simulated blood vessels 7 are connected to each other, and the simulated blood vessels 7 are connected to the groove 6, so that the liquid 11 can be in each simulated blood vessel 7.

[0026] In this embodiment, the semicircular piece 2, the round cover 3, and the threaded cover 4 are all made of PVC plastic.

[0027] The working principle of this device is:

[0028] During practice, medical students can follow the same steps as when practicing on a human body. When performing a correct intravenous infusion or blood draw, the liquid in the simulated blood vessel 7 flows into the needle. Medical students can practice repeatedly. The procedure is safe and can effectively improve the professional skills of nursing staff. When holding and rotating the semi-circular plate 2, the threaded cap 4 can be removed from the threaded groove 5. Medical staff can pour liquid 11 into the groove 6, and then the liquid 11 flows into the simulated blood vessel 7. The liquid 11 acts as blood. During practice, they can understand whether the simulation is correct and the puncture is accurate.

[0029] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention.
