The body 10 has at least three grooves 103, wherein the arm model 102 has at least two grooves 103, and the backhand model 101 has at least one groove 103. In the embodiment of the present invention, the main body 10 has three grooves 103, wherein the arm model 102 has two grooves 103, and the back of the hand model 101 has one groove 103. In other embodiments, three or more grooves 103 may be provided on the arm model 102 as needed; two or more grooves 103 may be provided on the back model 101. The grooves 103 meet at the arm model a area, i.e. all the grooves 103 are connected at the a area.
With continued reference to fig. 1, the recess 103 has a simulated blood vessel 104 therein, the simulated blood vessel 104 being a hollow catheter. In this embodiment, the simulated blood vessel 104 made of flexible PVC material is durable and renewable, has the characteristics of good elasticity, puncture resistance, no leakage, low price, replaceability, etc., and is an intravenous injection model with good simulation effect, durability, and capability of withstanding repeated punctures of nursing students to achieve skilled mastery. The back of hand model 101 and the arm model 102 are made of plastic. The simulated blood vessel 104 is arranged in the groove 103, is not easy to shift and can play a role in protection.
The liquid device 20 is composed of a liquid storage bag 201, a liquid inlet pipeline 202 and a liquid storage bag 203, wherein the liquid inlet pipeline 203 is provided with an adjusting switch 204 and a one-way valve 205. The regulating switch 204 comprises a pulley (not shown in the figure), when the pulley in the middle moves to the lowest position, namely the passage is closed, the liquid can not flow into the liquid inlet pipeline 202; when the middle pulley moves to the top, the channel is opened. The one-way valve 205, i.e., the control fluid, may only flow out of the reservoir 201, but not into the reservoir 201.
One end of the liquid inlet pipe 202 is connected with the liquid storage bag 201, the other end of the liquid inlet pipe 202 is connected with one simulated blood vessel 104(1) placed in the groove of the arm model, and the liquid accumulation bag 203 is connected with the other simulated blood vessel 104(2) placed in the groove of the arm model. The specific using process is as follows: before the simulation operation starts, the reservoir bag 201 is filled with simulation blood and is connected with one end of the liquid inlet pipeline 202, the other end of the liquid inlet pipeline 202 is connected with one simulation blood vessel 104(1) placed in the groove of the arm model, the liquid accumulation bag 203 is connected with the other simulation blood vessel 104(2) placed in the groove of the arm model, and it should be noted that the simulation blood vessel 104 only has two outlets which are respectively connected with the liquid inlet pipeline 202 and the liquid accumulation bag 203, and the other places are closed. The adjustment switch 204 is opened to pre-vent the simulated blood vessel 104 and maintain the patency of the fluid device 20. When intravenous injection is trained, the forearm of a simulated patient is tied by a tourniquet (at the moment, the main body 10 is fixed on the arm of the simulated patient), and the puncture blood return phenomenon in a clinical real scene can occur by puncture needle insertion, so that the functions of intravenous infusion and venous blood sampling are realized.
The liquid storage bag 201 can be hung on an infusion support to increase pressure so as to facilitate flowing into the simulated blood vessel 104, or the liquid inlet pipeline 202 is provided with the one-way valve 205, and the blood bag is squeezed by hands so as to enable liquid to flow out.
It should be noted that, the liquid accumulation bag 203 and the liquid inlet pipe 202 are both connected to the corresponding simulated blood vessel 104 through a spiral connector 208, and when the blood vessel 104 is damaged, the blood vessel is convenient to remove and replace. The stock solution bag 201 is provided with into liquid mouth and first screw lid 206, first screw lid 206 lid in go into on the liquid mouth, so, be convenient for at any time toward pour into liquid into in the stock solution bag 201. Similarly, the liquid accumulation bag 203 is provided with a liquid outlet and a second screw cap 207, so that liquid can be conveniently discharged from the liquid accumulation bag 203 at any time. The channel of the discharged and entered liquid is replaceable and convenient to disassemble.
It should be noted that a simulated skin layer (not shown in the figure) is arranged above the main body 10, and the simulated skin layer is made of TPU film material with an automatic repairing function, so that the vein model has the characteristic of automatic repairing and can be automatically repaired after being punctured repeatedly by nursing students. The simulated skin layer may be secured over the body 10 by snap-fastening or drawstring opening and closing. The TPU film material is a high molecular material between rubber and plastic and is named as thermoplastic polyurethane elastomer rubber. Since the simulated skin layer is a very thin layer, the position of the simulated blood vessel can be clearly determined through the simulated skin layer.
With continued reference to fig. 1, three pairs of velcro fasteners 105 are disposed on two sides of the arm model 102. The fabric is woven by nylon yarn, one fabric surface is woven with a plurality of looped piles (called 'suede' for short), the other fabric surface is woven with a plurality of uniform small hooks (called 'hook surface' for short), the looped piles are hooked only by slightly pressing the two belts after aligning, and the looped piles can be torn off only by slightly pulling outwards from the head end of the fastener, so that the fabric can play a role in connection to replace connection materials of buttons, press buttons, zippers and the like, and the fabric is characterized by being very convenient, time-saving, rapid and relatively soft to use. The Velcro 105 is arranged in pairs, one surface is a suede surface, and the other surface is a hook surface; in this manner, it is convenient to secure the main body 10 to the arm of a real person.
It should be noted that, in the embodiment of the present invention, the simulated blood vessel 104 also has intersection in the area a, but the present invention is not limited to the shape structure of the simulated blood vessel 104, and in other embodiments, the simulated blood vessel 104 may be a whole cylindrical hollow tube, and the same effect can be achieved by changing the placing route.
