Description

Wearable human body infusion model

Technical Field

The utility model belongs to model teaching aid field, concretely relates to human infusion model of wearing formula.

Background

At present, intravenous infusion is the most common treatment method in clinic and is the core technical capability which a nurse must have. Compared with other nursing operation skills, the intravenous infusion operation steps are more complicated, the sterility requirement is more strict, and more strict medicine checking, patient checking and explanation are required in the operation. In general, each medical institution teaches the skill by model teaching or human practice or a combination of both, and the two teaching modes have advantages but different disadvantages.

There are many studies that have been developed to improve upon the intravenous infusion model. The improvement of the infusion model mainly focuses on the following aspects:

1. infusion models for different ages: because the thickness of the main infusion part or blood vessel selected at different age stages is very different, there are "infant scalp venous infusion model for teaching" (guoyinghua, qixiu celery, infant scalp venous infusion model for teaching. utility model application No. CN201220141104.0,2012, 11 month and 14 days) "and" complete assessment guidance model for newborn scalp venous infusion (Zhangmei, Zhang daoyi, chaoshuang, etc.. complete assessment guidance model for newborn scalp venous infusion. utility model application No. CN201120260769.9, 2012, 7 month and 18 days) ", there are" pediatric arm venous infusion model (Zhang hua, Tianrui, Yan bamboo, etc.. pediatric arm venous infusion model application No. CN200920251195.1,2009, 12 month and 2 days "," pediatric lower limb venous infusion model for pediatrics (Zhang hua, Tianrui, Yan bamboo, etc.. pediatric lower limb venous infusion model application No. CN200920251196.6,2009, 12 year and 2 days) ", for children, "child infusion teaching device (li jianlan child infusion teaching device, utility model application No. CN201520123296.6,2015, 3 months and 3 days)" and other intravenous infusion models for adults.

2. Structural design for simulating blood flow: the transfusion model has the common points that the transfusion model is provided with a blood inlet and a blood outlet, the simulated blood enters the simulated blood vessel from the blood inlet, and the blood outlet is opened after the transfusion model is trained to flow out. In order to form a pressure difference to enable the simulated blood to be filled into the simulated blood vessel, a general design is that the simulated blood bag is hung high to enable the level of the simulated blood bag to be higher than that of a transfusion model, so that the simulated blood enters a tube cavity under the action of gravity, and a pressure pump is adopted to enable the simulated blood to circularly flow in the blood vessel.

3. And (3) construction of a model module: taking the arm model as an example, the model generally includes simulated skin, simulated muscle and blood vessels. Most of the puncture parts are provided with independent detachable modules, so that the puncture parts can be replaced locally, resources can be saved, and material cost can be reduced. Another design is an integrated molding design (Renmitemin, Chenhong, Lichangji, etc. complete set of assessment guidance model for intravenous transfusion simulation hands, Utility model application No. CN201120260836.7,2012, 7 months and 11 days), such as using an arm model as a carrier, simulating real muscle by using a polyurethane foaming filler and embedding a simulated blood vessel therein. In another blood vessel embedding mode, an open circular groove is designed on a model, a simulated blood vessel net is embedded, and the outer layer is covered with detachable simulated skin, so that the blood vessel can be replaced in the future.

4. There is also an example of a design that is closer to this study: the utility model discloses a patent of "wearing formula venous transfusion hand model" has been announced in 2011 white flood sea etc. (white flood sea, Cao concubine, a wearing formula venous transfusion hand model utility model patent application number CN201020256093.1, 9 days in 2010 7 months), can wear in real person's hand, and its hand model includes hand skin, hand module, the hand module divide into upper and lower two parts, back and palm promptly, whole module parcel forearm hypomere and palm, the back of the hand, both sides limit are equipped with opening and the closed mouth that closes that realizes the module, are equipped with the blood vessel groove on the face of back module, hand skin sets up the hand module is outside.

According to the analysis, both the venous transfusion model teaching method and the real person teaching method have advantages and disadvantages, and the venous transfusion model teaching method has the advantages that the method can be repeatedly practiced, but is far away from clinical situations, and students are difficult to have clinical substitution feeling. The advantages of real people are that the method can simulate clinical practical situations better, has no barrier to interaction and communication with patients, can experience the feelings of the patients in operation, and is helpful for students to develop idea of love injuries, but the method has ethical disputes and can not be carried out for many times.

The design of the related patents of the venous transfusion of the above items except the utility model of the wearable hand model of the venous transfusion can not highly simulate the clinical situation, and has the defects of incapability of interactive communication, incapability of cooperating with the operation (fist making and fist making) by an operator, incapability of expressing the feeling by the operator and the like; the design of the utility model of the wearable hand model for intravenous infusion is similar to the research in the original purpose, namely the advantages of a real person and the advantages of the model are combined, but the design has great defects, such as the design of a blood inflow and hemorrhage system is not concealed enough, and the realization of simulating the blood flow in blood vessels needs not only another device, but also one person needs to lift the device, so the device is inconvenient, and the barrier is formed to the clinical situation substitution sense; a large amount of simulated blood is required to be prepared each time the blood simulator is used, so that huge waste is caused; blood in the simulated blood vessel can not be filled when a fist is clenched, and blood can not return after the needle is inserted, so that the difference from clinical practice is large. Another drawback of the design is that the model comprises a lower forearm, and the tourniquet is tied on the model during infusion, so that even if the tourniquet is tied for too long due to the slow operation speed of an operator, the infused object does not have any discomfort, which is extremely not practical and is not beneficial to the culture and formation of the time concept and the love concept of the infusion operator; compared with the design, the device with the design occupies too much space and is not convenient to use.
