Description

A blood collection practice device

technical field

The utility model relates to a blood collection exercise device. the

Background technique

Blood collection is the most important operation item in the blood station. There are a large number of blood collection tasks almost every day. In order to improve the operation level of business personnel, it is very necessary to use some simulation facilities for training. Although there are some related designs for these simulation facilities, they also have different problems, and it is difficult to meet the actual needs. the

Contents of the invention

The purpose of the invention of the utility model is to provide a blood collection training device, which has multiple functions and can significantly improve the training efficiency. the

The technical scheme of the utility model is: the blood collection practice device is a plane multi-layer structure, the bottom layer is the base layer, made of opaque cardboard, and glue is attached on the upper surface. The top of the base layer is a performance observation layer made of transparent plastic, and the base layer and the performance observation layer are bonded with glue. On the upper surface of the performance observation layer, there is a square-shaped area division frame, the width of the area division frame is 0.5 to 1 cm, and the cutting marking line corresponding to the area division frame is pasted on the bottom surface of the base layer. Marking lines are omitted. The area division frame divides the upper surface of the performance observation layer into multiple rectangular operation areas with the same shape. There are multiple blood vessel models in the rectangular operating area. The blood vessel models are made of arc-shaped latex tubes with both ends closed. The diameter of the arc-shaped latex tubes is similar to that of human veins and contains red liquid. The blood vessel models are arranged irregularly on the upper surface of the operating area, and are glued to the performance observation layer with glue. There are a large number of sheet-shaped plastic bags in the void area of the blood vessel model in the operating area, and black liquid is filled in the plastic bags. Above the performance observation layer is a covering layer, which is formed by compounding opaque adhesive tape and foam. The cover layer is provided with multiple layers, and the convex outline of the blood vessel model of each cover layer is obvious layer by layer from the outside to the inside. Adhesive bonding is used between the performance observation layer and the covering layer. the

The usage method of the present utility model is: at first determine the layer number of cover layer according to need, if want to reduce operation difficulty, wherein part of cover layer can be thrown off. After finding the blood vessel model, the practitioner uses a blood collection needle to collect red liquid from the blood vessel model. If judgment and operation errors occur, insert the needle into the plastic bag, and the black liquid will flow out. After the practice, turn the device over, tear off the base layer, and you can observe the operation performance through the transparent performance observation layer. the

The utility model has the advantages that the difficulty of operation can be adjusted, and it is suitable for training at different technical levels. In this design, both operational achievements and mistakes can be displayed, and it is also very convenient for observation. Because the device is a planar product, and the design structure is also very simple, it is also particularly easy to manufacture. the

Detailed ways

For example shown in Fig. 1, Fig. 2, Fig. 3, this blood collection practice device is a plane multi-layer structure, and the bottom layer is the base layer 1, made of opaque cardboard, with glue on its upper surface. The top of the base layer 1 is made of transparent plastics to make the performance observation layer 2, and the base layer 1 and the performance observation layer 2 are bonded with glue. On the upper surface of the performance observation layer 2, a square-shaped region division frame 3 is pasted, and the width of the region division frame 3 is 0.5 to 1 centimeter, and a cutting mark corresponding to the region division frame 3 is pasted on the bottom surface of the base layer 1 Line, the cutting mark line is omitted in the figure. The area division frame 3 equally divides the upper surface of the performance observation layer 2 into a plurality of rectangular operation areas 4 with the same shape. A plurality of blood vessel models 5 are arranged in the rectangular operating area 4, and the blood vessel models 5 are made of arc-shaped latex tubes closed at both ends. The diameter of the arc-shaped latex tubes is similar to the blood vessels of human veins, and red liquid is housed therein. The blood vessel model 5 is irregularly arranged on the upper surface of the operating area, and is stuck on the performance observation layer 2 with glue. A large number of sheet-shaped plastic bags 6 are arranged in the void area of the blood vessel model 5 in the operating area, and black liquid is housed in the plastic bags 6 . Above the performance observation layer 2 is a covering layer 7, which is formed by compounding opaque adhesive tape and foam. The cover layer 7 is provided with multiple layers, and the convex contours of the blood vessel models 5 of each layer are obvious layer by layer from the outside to the inside. Adhesive bonding is used between the performance observation layer 2 and the covering layer 7 .
