Background
Intravenous infusion and intravenous blood sampling are the most commonly used treatment and care techniques in hospital clinics, and are also the operating skills that nurses must master. However, in the training teaching of venipuncture, if the training of puncture by a real person is adopted, the student is extremely burdened with psychological burden, physical stabbing, potential infection and other injuries, and the training cannot be repeated for many times, so that the training effect of skilled mastering is difficult to achieve. The use of the arm model for intravenous infusion solves these problems to some extent.
At present, two types of common intravenous puncture transfusion arm models exist in the market, namely a simple transfusion arm model, namely a simple simulation arm, and a simulation blood vessel is arranged in the arm, but the model has some problems. The simple infusion arm model is low in price, the function of inputting liquid into veins can be met, the simulated blood drawing technology is difficult to realize, blood return is not visible during intravenous infusion and blood collection, errors are difficult to judge in teaching and examination, and the liquid cannot be recovered in time after infusion. Because the infusion device cannot be disassembled and washed at will (the assembly after disassembly is difficult), even if a learner fails to puncture during the intravenous infusion operation, the liquid can be dripped, so that the problem of learning cannot be found in time.
The other model is an advanced infusion arm model, which consists of a simulated arm and a peristaltic pump (an electronic blood circulation device). The two vein puncture transfusion arm models are composed of three parts, namely simulated skin subcutaneous tissue, arm bone and simulated blood vessel. The simulated skin subcutaneous tissue is made of plastic materials, the blood vessel is made of latex materials, the arm bone is made of PVC materials, the integrated molding is carried out, and vein vascular networks are distributed on the arm. The advanced infusion arm model can meet the functions of intravenous infusion and intravenous blood sampling, obvious blood return can be seen during the intravenous infusion and the blood sampling, puncture training functions such as intravenous injection, infusion (blood), blood sampling and the like can be carried out, teaching and assessment are convenient, but the model is high in price, the training needs cannot be met when the number of students is large, the model is easy to damage after repeated puncture, vascular leakage is caused, the service life is short, and the maintenance cost is high.

Detailed Description
In order to make the present invention better understood by those skilled in the art, the following description will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 4, fig. 1 is a front view of a main body 10, fig. 2 is a cross-sectional view of the main body 10 taken along A-A' in fig. 1, fig. 3 is a front view of a glove 20, and fig. 4 is a schematic view of connection of the main body 10 and a liquid device 30. The invention relates to a wearable hand transfusion and blood sampling simulation demonstration device, which comprises: a body 10, a glove 20 and a fluid device 30, said body 10 comprising an arm region 100 and a palm region 101.
Referring to FIG. 2, FIG. 2 is a cross-sectional view of the body of FIG. 1 taken along line A-A'. The main body 10 has five layers, namely a bottom layer 1001, a first simulated muscle layer 1002, a simulated blood vessel layer 1003, a second simulated muscle layer 1004 and a simulated skin layer 1005 from bottom to top, and the bottom layer 1001 and the simulated skin layer 1005 are provided with corresponding second nylon fastener tapes 1006. The second nylon fastener tape 1006 is a fabric textile woven by nylon, one fabric surface is woven with a plurality of loops (short for "suede"), the other fabric surface is woven with a plurality of even small hooks (short for "hook surface"), and the loops are hooked by only slightly squeezing the two tapes after aligning and can be torn only when being pulled slightly outwards from the head end of the fastener, so that the second nylon fastener tape 1006 can play a role of connection to replace the connection materials of buttons, snaps, zippers and the like. In the embodiment of the present invention, the second velcro strap 1006 is disposed on a side of the bottom layer 1001 near the first muscle layer 1002; the second velcro 1006 is disposed on a side of the simulated skin layer 1005 adjacent to the second simulated muscle layer 1004. The second velcro strips 1006 provided on the bottom layer 1001 and the skin-like layer 1005 may be a suede surface provided on the bottom layer 1001, and a hook surface provided on the skin-like layer 1005; alternatively, the simulated skin layer 1005 may be configured as a suede, and the bottom layer 1001 may be configured as a hook surface. Referring to fig. 5, fig. 5 is a top view of the bottom layer 1001 of the main body 10, and the second velcro strips 1006 are disposed on a surrounding area of the bottom layer 1001.
Corresponding second velcro strips 1006 are provided through the bottom layer 1001 and the simulated skin layer 1005, thus facilitating the removal of the body 10 portion and replacement of the various layers of fittings therein. The first simulated muscle layer 1002, the simulated blood vessel layer 1003, and the second simulated muscle layer 1004 in the body 10 may be replaced. For example, referring to fig. 6, fig. 6 is a top view of the blood vessel layer 1003 in the body 10. In the embodiment of the present invention, the simulated blood vessel layer 1003 is a hollow catheter. The simulated blood vessel layer 1003 is fixed on the first simulated muscle layer 1002 by a plurality of fixtures 1007, and the hollow catheter (the simulated blood vessel layer 1003) can be removed by opening the fixtures 1007, so that the simulated blood vessel layer 1003 can be replaced at any time. For example, when a person who is fat is found in practice, the blood vessel is thicker, and when a child is found, the blood vessel is thinner, so that the blood vessel can be flexibly adjusted according to the training case, different human blood vessel thicknesses can be flexibly simulated by replacing a thicker or thinner catheter, and the effect of changing the blood vessel position can be achieved by changing the arrangement line of the catheter. It should be noted that, in the embodiment of the present invention, the number of the holders 1007 is 3, and in other embodiments, more or fewer holders 1007 may be provided according to actual needs, which is not limited to this embodiment. In addition, the simulated blood vessel layer 1003 in fig. 6 is only shown to be disposed on the arm region 100, however, in other embodiments, the palm region 101 may be disposed on the simulated blood vessel layer 1003 as required, which is not shown in fig. 6. The palm area 101 and the arm area 100 belong to the body 10, and the structures are the same, except that the palm area 101 is provided with the first fastener tape 201.
Above the simulated blood vessel layer 1003 is a second simulated muscle layer 1004, in order to simulate subcutaneous tissue and muscle tissue, because blood vessels of a human body are not directly under skin and should be in subcutaneous tissue and muscle tissue, the second simulated muscle layer 1004 is used for simulation, and since the whole main body 10 is detachable, we can flexibly change the thickness of the second simulated muscle layer 1004 by replacing the second simulated muscle layer 1004, for example, when simulating the elderly, the second simulated muscle layer 1004 is thinner, thus the blood vessels are more obvious for external observation, when simulating the obese people of a pregnant woman, the blood vessels are deep, and the appearance is not obvious, at this time, the thickness of the second simulated muscle layer 1004 is thicker, or the thickness of the second simulated muscle layer 1004 is relied on for representation. With continued reference to fig. 2, in an embodiment of the present invention, the thickness of the first simulated muscle layer 1002 is greater than the thickness of the second simulated muscle layer 1004. In other embodiments, the first muscle layer 1002 may be configured to be non-detachable and fixed on the bottom layer 1001, and because the first muscle layer 1002 is configured to be thicker and fixed, the condition that the simulated patient is stabbed during training can be effectively avoided.
With continued reference to fig. 1 and 3, a plurality of third velcro strips 102 are disposed on two sides of the arm area 100 in a one-to-one correspondence; the palm area 101 and the glove 20 are provided with corresponding first nylon fastener tape 201. The wearable hand transfusion and blood sampling simulation demonstration device provided by the invention can be worn on the hands of a person, so that transfusion and blood sampling processes can be simulated more realistically. The glove 20 may be worn on a hand of a person, the arm region 100 of the main body 10 is fixed on the arm of the person through the third nylon fastener tape 102, the palm region 101 is fixed on the glove 20 through the first nylon fastener tape 201, and the wearing and the fixing are more convenient through the design of the nylon fastener tape 201. The first velcro tape 201 provided on the glove 20 is provided on the back and/or the palm of the glove 20. It should be noted that, when the intravenous infusion is performed in the palm area 101, the back of the hand should be facing up, and the medical staff should simulate the operation on the back of the hand, and at this time, the first velcro tape 201 on the glove 20 should be located at the palm position, specifically, for example, in fig. 3, when the first velcro tape 201 on the glove 20 is located at the palm position, the glove should be worn on the right hand, that is, when the intravenous infusion is simulated, the glove should be worn on the right hand. The venous blood collection is performed in the arm area 100 with the palm facing up during the simulation, and again, for example, in fig. 3, the glove 20 should be worn on the left hand when the first velcro tape 201 is positioned on the back of the hand, i.e., the glove should be worn on the right hand when the venous blood collection is simulated. Of course, in other embodiments of the present invention, it is also possible to provide a glove that is worn on the left hand when the first velcro tape 201 on the glove 20 is in the palm position, and only the position of the first velcro tape 201 needs to be changed. So set up, as long as change the gloves and wear in the position of left hand or right hand simply, can easily change the position of first nylon fastener tape, the simple operation, simple structure, the cost of manufacture is low. Of course, the first velcro tape 201 may be provided on both the back and the palm of the glove 20 according to actual needs, and then, it may be selected which of the first velcro tapes 201 is to be attached according to operation needs.
With continued reference to fig. 4, fig. 4 is a schematic illustration of the connection of the body 10 and the liquid device 30. The liquid device consists of a liquid storage bag 301, at least one liquid inlet pipeline 302 and a liquid recovery bag 303, wherein the liquid inlet pipeline 302 is provided with an adjusting switch 304; the regulating switch 304 includes a pulley (not shown), and when the middle pulley moves to the lowest position, the channel is closed, and the liquid cannot flow into the liquid inlet pipeline 302; the passage is opened when the middle pulley is moved to the uppermost. One end of the liquid inlet pipeline 304 is connected with the liquid storage bag 301, the other end of the liquid inlet pipeline 304 is connected with one end 1003 (1) of the simulated blood vessel layer, and the other end 1003 (2) of the simulated blood vessel layer is connected with the liquid recovery bag 303. In other embodiments of the present invention, two liquid inlet pipes 302 may be included, and the other end 1003 (2) of the simulated vascular layer and the liquid recovery bag 303 may also be connected to each other through another liquid inlet pipe 302. The specific using process comprises the following steps: before the simulation operation starts, the simulated blood is filled in the liquid storage bag 301 and connected with one end of the liquid inlet pipe 302, the other end of the liquid inlet pipe 302 is connected with one end 1003 (1) of the simulated blood vessel layer, 1 the other end 1003 (2) of the simulated blood vessel layer is connected with the liquid recovery bag 303, the regulating switch 304 is opened, air in the simulated blood vessel layer 1003 is discharged in advance, and the smoothness of the liquid device 30 is maintained. When training vein blood sampling, the forearm of a simulated patient is fastened by the tourniquet (the main body 10 is fixed on the arm of the simulated patient at the moment), and the puncture blood return phenomenon in the clinical real scene can occur after the puncture needle is inserted, so that the functions of vein transfusion and vein blood sampling are realized.
The bottom layer 1001 is in direct contact with the back and/or palm and forearm skin of the hand of the simulated patient wearing the glove 20, and is made of a water-impermeable plastic material, for example: polyethylene or polyvinyl chloride. The skin simulating layer 1005 simulates human skin, and is made of soft, airtight and elastic plastic material, such as silica gel material. The first simulated muscle layer 1002 and the second simulated muscle layer 1004 simulate human muscle, and cotton pads can be used, so that the thickness is easier to control.
The device provided by the embodiment of the invention has strong practicability, can be used for demonstration teaching and training of two skills of simulating venous transfusion and venous blood sampling and drawing, can flexibly change the thickness of blood vessels and the circulating route according to the needs, realizes the depth change of the simulated blood vessel position by changing the thickness of the cotton pad, achieves the clinical high simulation effect, and better improves the operation strain capacity and the clinical thinking judgment capacity of learners. When the device is worn by a simulated patient during simulated training or examination, the device can be effectively interacted and communicated with a learner by combining clinical cases, so that the learner is more interesting to learn, and the learning interest and the humanistic care literacy of the learner are improved.
In addition, the invention is convenient for accurately judging the operation result of a practitioner. The existing model can not be disassembled and washed at will or is difficult to install after being disassembled, and even if a practitioner fails to puncture during intravenous infusion operation, liquid can be dripped, so that the problem can not be found in time.
