Abstract
The utility model relates to an electronic catheterization, sausage nursing teaching model. A model can generate the similar physiological coordination reaction when the urethral catheterization operation is conducted by the lower body model of a normal human body, which is made of PVC latex plastic, 'organs' (urethra, bladder and rectum) arranged in the body, an electronic optically controlled system arranged on the 'organs' and a signal automatic display facility.
Description
The utility model relates to a kind of novel electron urethral catheterization, bowel lavage nursing teaching model, part " internal organs " (comprises enteron aisle in the normal human's lower part of the body model made by the PVC plastic cement and the body thereof, urethra and bladder) and " internal organs " on compositions such as electronic light-controlled facility, its technical essential is: one) utilize " internal organs " are upward installed in the model body electronic light-controlled system and external signal controller and two) utilize " urine " that from model bladder, derive to have the characteristics of similar physiological pressure, make model in urethral catheterization, during the bowel lavage operation, the characteristics that produce similar physiological pressure make model in urethral catheterization, during the bowel lavage operation, produce similar physiological mutual aid reaction, to strengthen the sense of reality.
In the existing similar technology, do not see the report (seeing Table and look into new data) of identical with the utility model technical scheme and products thereof both at home and abroad.Existing procucts all rely on manual operation, do not have electronic light-controlled and signal to show facility automatically.
The purpose of the novel electron teaching mode that the utility model proposes makes model produce similar physiological mutual aid reaction when being urethral catheterization, bowel lavage operation rehearsal, to improve the effect when participating in the cintest of nursing teaching.

One, the general structure of novel electron teaching mode
(1) image appearance of this model is made according to the height 160Cm normal human lower part of the body bodily form, and the model upper end starts from third lumbar vertebra, and the top becomes a square section, and the lower end terminates in sole, and its overall height is 90cm.
(2) hipbone is connected with thigh (femur) top, forms hip joint, and hip, knee joint all become pivoting to connect, can abduction 60 degree activities to adapt to two legs.
(3) active face that can unload is made at 1/3 place on the thigh, so that use when decomposing teaching.
(4) 1.5cm place and both sides femur ditch are all made the state of dissecing under lower margin of pubic bone, the anus, fix with nylon adhesion, can change parts rapidly when being convenient to demonstration lesson.
Two, the pelvic cavity inner structure of novel electron teaching mode
(1) " internal organs " such as urethra, bladder and enteron aisles of simulating are installed in the pelvic cavity, urethra and enteron aisle are equipped with row, storage liquid systems (Fig. 1).
(2) on " internal organs " (urethra, bladder and enteron aisle) electronic light-controlled system and signal automatic display unit are housed in the pelvic cavity, so that when urethral catheterization and bowel lavage operation rehearsal, make model produce similar physiological mutual aid reaction, this is one of important difference point with prior art with the sense of reality that strengthens operation.
(3) model lumbar vertebra square section has hole, shrouding garden, the left and right sides, so that assembling or breakdown shrouding when checking the pelvic cavity inner facility.Side opening has half garden plate, and breakdown is convenient to bolster model and is left lateral position at any time, to adapt to the bowel lavage operation.
Three, novel electron teaching mode urethral catheterization operation
(1) before the water filling urethral catheterization, with syringe 200～250ml clear water is injected from water inlet (I-9) earlier, enter in the rubber bag tank (bladder) (I-11) that is rich in strong elasticity stand-by through retaining valve.Rubber bag tank has three import and export, and respectively by retaining valve (I-7), solenoid valve (DCT) (I-6) and (I-8) shutoff of adjustable spiral folder are in case leak.
(2) because bladder is to select for use the specific rubber material to make, is rich in strong elasticity, also has certain pressure when causing the moisture content that is stored to be discharged, when teaching operation, can utilize this kind pressure to simulate normal person's bladder is given urine when urinating physiological pressure, to improve the effect when participating in the cintest of operation rehearsal.This is and two of prior art important difference point.
(3) male urethra and urethral catheterization
Urethral catheterization operation beginning is 60 degree with the outer urethra hemad of the male sex earlier and mentions, and urethra curvatura praepubica pars convoluta (I-3) exhibition is straight in making, so that catheter is smoothly by herein, by the time external signal display unit show green signal automatically, if operate undesirablely, then do not have reaction signal.
When catheter enters 20cm depths (when promptly arriving bladder), red signals shows that automatically the expression catheter needn't go deep into again, has 200ml " urine " to derive external from catheter simultaneously.
(4) women's urethral catheterization
Earlier model two side hip joints of lying on the back and lower limb are 60 the be outside one's consideration gesture of showing beauty and fix, catheter inserts urethra 4cm depths (promptly having arrived bladder), and red signals shows automatically, and the 200ml that has an appointment " urine " discharges from catheter.
Four, electronic light-controlled system and external signal show response procedures and principle thereof automatically in the body
(1) be example with male sex's urethral catheterization, before the operation beginning, after the model energized, signal light in two light-operated heads (I-3, I-5) is promptly bright, makes two photoelectric tubes (D1D2) be in bright resistance situation, it is static that model is, and this moment, J1, J2 did not produce the action work, and outward appearance is reactionless.
(2) operation beginning, catheter is slowly inserted from urinary catheter mouth (I-1), when arriving the light-operated head of curvatura praepubica pars convoluta (I-3), D2 illumination is by the catheter shield, and this moment, J2 produced action, curvatura praepubica pars convoluta signal light on the external urethral catheterization signal controller is bright simultaneously, the expression catheter can continue deeply, and when catheter stretched into the arrival light-operated head in orificium urethrae internum (I-5), D1 illumination also was blocked, J1 promptly begins action, drives solenoid valve (DCT) (I-6) and opens; Because DCT is open, " urine " that have pressure in the rubber bag tank (bladder) derives external immediately by DCT through catheter.Represent the signal light of orificium urethrae internum bright on the external signal controller simultaneously, expression is all finished the male sex's urethral catheterization operation.As catheter is taken out, DCT closes immediately, and " urine " promptly stops to derive, and all signal light extinguishes.
(3) in the figure II set two filtered electrical of C1, C2 molten be in the moment that begins to switch on, when illumination does not reach required value, for preventing that J1, J2 from producing unnecessary action and confusing running program setting.
Five, enteron aisle structure and bowel lavage operation
(1) anus (I-12) upper end is a rectum, be positioned at the rear side of pelvic cavity bladder, the rectum lower end has the upper end of sensitive unidirectional electrical magnet valve (I-13) intestines that one water storage bag (I-16) is arranged, there is water inlet pipe (I-15) upper end of water storage bag with tight adjustable screw clamp (I-a 14) shutoff, to keep priming charge non-leakage, do not flow backwards.
(2) before the bowel lavage, half garden plate of first breakdown model left lumbar region is in left lateral position to support whole model.
(3) glycerine is coated on the anal tube top of enema syringe, slowly insert anus (I-12) to the 12cm place, can pour into " bowel lavage liquid " about 200ml to water storage bag (I-16), slowly extract intubate then, because of what install on the enteron aisle is retaining valve, and bowel lavage liquid does not flow backwards.So far, the bowel lavage operation has been accused and has been finished.
