Using the medical teaching of the utility model structure or the puncturing pattern of training, meet needed for suitable teaching mode
The following requirement having: firstly, it simulates whole operation program close to true environment;Second, it, which is provided, accurately feels anti-
Feedback, that is, the feel being commonly called as;Third can be used, it is ensured that all students can repeatedly practise behaviour with the multiple copies of quick copy
Make;4th, model component is readily replaceable and cheap, and the combination of entire model is low in cost;Finally and most of all,
Model can increase student to the understanding of operating process, the operation confidence of raising student.
In the utility model, using plastics by microwave furnace cutlery box as support device, fill water medical aseptic gloves simulate
Bladder is packed for foamed plastics simulation abdominal wall structure, and orthopaedics simulates the skin and rectus aabdominis for being located at stomach wall with elastic force self-adhering fascia
Protheca, therefore structure is simple, low cost, easily prepares, is rare practical teaching model.Pass through test of many times, it was demonstrated that this letter
Single model can imitate the whole operation process of punctio vesicae fistulization, and operating handle is similar, and it is bright that sense is broken through when especially puncturing
Aobvious and practical operation is closely similar, and cheap and simple can be replaced repeatedly rapidly, achievees the effect that model is recycled.
In all simulation puncture process, UROVISION punctio vesicae fistulization suit can be used, entirely puncture through
Journey and the unique small difference of standard punctio vesicae fistulization program are that this set tubing is placed in puncture needle in advance, single step operation
It completes to puncture and set pipe process, using conveniently, reliably, the wider application of suprapubic tract should be peomoted.This is practical
The step of proposition, is identical in puncture suit and all operations step and Reuter that new structure model uses et al. article,
When only last puncture is completed, puncture needle is not torn to pieces, puncture needle and its conduit Reusability.The tradition mark proposed compared with Goyal
Quasi- method eliminates the process that puncture needle core places conduit again of pulling out, only with being placed in conduit in advance in puncture sheath needle.
It is imparted knowledge to students using this model, medico can be made to understand and learns all operationss process of punctio vesicae fistulization by heart,
And breakthrough sense when penetrating bladder is realized in operation, and this feel is never realized in other training on operations.
By the operation video recording for watching all students, hence it is evident that it can be seen that pause when break-through simulation bladder, at this moment puncture needle is again into 1cm
Urine postposition pipe is flowed out in left and right, observation tube tail portion.By questionnaire survey, all students have smoothly completed above-mentioned steps, and declare
Title has realized breakthrough sense, and 87.5% student declares in clinical practice from now on, needs to do the tight of bladder stoma if encountered
Anxious situation, it is confident to carry out all operationss.
Although the model of the modelling of the utility model structure is fairly simple, only foamed plastics simulation stomach wall layer
Secondary, the skin layer of orthopaedics self-adhering fascia simulation is pasted on medical rubber glove surface and reinforces simulation punctio vesicae face, prevents from puncturing
When gloves explosion orthopaedics self-adhering fascia, but this modelling is simple, and cheaply, outer except puncturing suit, entire model is worth only
It is about 2 dollars, very cheap compared to the model prices that Ashima Singal is worth 31.28 dollars, and production is convenient rapidly, only needs
The simulation bladder and simulation stomach wall layer for replacing a gloving just use for next student, and replacing construction 5 minutes or so,
Therefore, can with large supply student not by the time not by the training in place.
