Wearable human body infusion model and using method

Abstract

The invention discloses a wearable human body infusion model and a using method, the infusion model is provided with a trunk model, the trunk model can be sleeved on the corresponding trunk of the human body in use, the mode of combining a real person with the model is realized, the infusion operation can be simulated more visually and vividly, blood pressure is provided for the simulated blood vessel through the pressure pump set, the simulated blood vessel is covered with the simulated skin, the actual skin and blood pressure of the human body can be accurately simulated, and the infusion model is closer to the actual situation.

Description

technical field [0001] The invention belongs to the field of model teaching aids, and in particular relates to a wearable human body infusion model and a using method. Background technique [0002] At present, intravenous infusion is the most commonly used clinical treatment method, and it is also the core technical ability that nurses must possess. Compared with other nursing operation skills, the operation steps of intravenous infusion are more complicated, the requirements for sterility are stricter, and stricter drug check, patient check and explanation are required during the operation. Usually, medical colleges use model teaching or real practice or a combination of both to teach this skill. Both teaching modes have their own advantages but also have different disadvantages. [0003] At present, many studies have improved the intravenous infusion model. The improvement of the infusion model mainly focuses on the following aspects: [0004] 1. Infusion models for dif...

[0008] According to the above analysis, there are advantages and disadvantages in both the teaching method of intravenous infusion model and real person teaching. The advantage of teaching intravenous infusion model is that it can be practiced repeatedly, but it is far from the clinical situation, and it is difficult for students to have a sense of clinical substitution.

The advantage of a real person is that it can better simulate the actual clinical situation, interact with the patient without barriers, and experience the patient's feelings during the operation, which helps students cultivate the concept of love and injury. However, this method is ethically controversial and cannot be used too much. times performed

[0009] Except for the utility model patent of the "wearable intravenous infusion hand model", the above-mentioned IV infusion-related patent designs cannot highly simulate clinical scenarios, and there are problems such as inability to interact and communicate, and the operator cannot cooperate with the operation (clench and loosen fists) However, the original design intention of the utility model patent of the "wearable intravenous infusion hand model" is very close to this research—combining the advantages of real people and models, but there are still many problems in its design. Big flaws, such as the design of the blood inflow and hemorrhage system are not concealed enough, and the realization of the simulation of blood flow in blood vessels not only requires another device, but also requires one person to hold the device, which is very inconvenient and hinders the sense of substitution in clinical scenarios; Prepare a large amount of simulated blood, resulting in huge waste; the blood in the simulated blood vessel cannot be filled when making a fist, and the blood cannot return after the needle is inserted, which is quite different from the clinical practice

Another defect of this design is that the model includes the lower part of the forearm, and the cuff is fastened to the model during infusion, so even if the cuff is fastened for too long due to the slow operation speed of the operator, the infused object will not There will be any discomfort, which is extremely inconsistent with the actual situation, and is not conducive to the cultivation and formation of the concept of time and love and injury of the infusion operator; the device of this design seems to take up too much space compared with our design, and it is not very convenient to use
