Description

Blood collection practice device

technical field

The invention relates to a blood collection practice device.

Background technique

Blood collection is the most important operation item in blood stations and major hospitals. 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.

Contents of the invention

The purpose of the present invention is to provide a blood collection practice device, which has multiple functions and can obviously improve the practice efficiency.

The technical solution of the present invention is: the blood collection practice device is a plane multi-layer structure, the bottom layer is the base layer, made of opaque cardboard, and transparent glue is attached on the surface of the opaque cardboard. 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 transparent glue. On the upper surface of the performance observation layer, there is a square-shaped area division frame. The line width of the area division frame is 0.5 to 1 cm. On the bottom surface of the base layer, there are cutting marking lines corresponding to the area division frame. Marking lines are omitted. The area segmentation 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 closed ends. The diameter of the arc-shaped latex tubes is similar to that of human veins, and red liquid is contained in the arc-shaped latex tubes. The blood vessel model is irregularly arranged on the upper surface of the rectangular operating area, and is 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 rectangular 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 method of use of the present invention is: firstly, the number of layers of the cover layer is determined according to needs, and part of the cover layer can be removed if the operation difficulty is to be reduced. 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 advantage of the present invention is firstly that the operation difficulty 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 product of the present invention can be cut into small pieces of various sizes and used as planar products, and can also be wrapped on the outer surfaces of some limb models for making three-dimensional models.

detailed description

For example, as shown in Fig. 1, Fig. 2 and Fig. 3, the blood collection practice device is a planar multilayer structure, the bottom layer is the base layer 1, which is made of opaque cardboard, and transparent glue is attached on the surface of the opaque cardboard. 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 transparent glue. On the performance observation layer 2 upper surface, a square-shaped region division frame 3 is pasted, and the line 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 that of human veins, and red liquid is housed in the arc-shaped latex tubes. The blood vessel models 5 are irregularly arranged on the upper surface of the rectangular operating area 4, and are 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 rectangular operating area 4 and the blood vessel model 5, 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 outline of the blood vessel model 5 of each cover layer 7 is 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 .
