Description
Technical field
The utility model relates to medical lecture model, relates in particular to a kind of interior impotence model of arteriovenous of internal fistula operation.
Background technology
Internal fistula art is a kind of minor operation of vascular anastomosis, forearm is done to one near the artery at wrist position and contiguous vein and sew up, and the arterial blood that makes flowing in the vein after coincideing, forms an internal arteriovenous fistula.The blood vessel of internal arteriovenous fistula can provide sufficient blood for hemodialysis, for the adequacy of dialysis treatment provides safeguard.
In field research process, mostly the study of internal fistula art is empathic learning, seldom carries out practical operation, and proficiency, the accuracy of medico to this technical ability can not be accepted by clinical.Be badly in need of a kind of can analogue simulation internal fistula the platform of training.
Summary of the invention
The purpose of this utility model is to provide a kind of internal arteriovenous fistula model, carries out the training of internal fistula art technical ability for medico, mainly comprises simulation arm, simulated skin, a simulate blood circulating device;
Described simulated skin adopts resilient material to make, and is convenient for changing;
It is characterized in that:
Described simulation arm adopts the plastics one-shot forming of hard, comprising simulation artery and vein blood vessel, reserved location is installed, and simulated skin is installed reserved location;
Described simulate blood circulating device by simulate blood charge pump by be communicated with communicating pipe outer arteries blood vessel, after by be communicated with communicating pipe operative segment arteries, the U-shaped connecting pipe of rear connection, rear connection operative segment vein blood vessel, after by be communicated with communicating pipe outside vein blood vessel, after by being communicated with simulate blood charge pump communicating pipe, for simulate blood circulation, be placed in simulation arm, and operative segment arteries, operative segment vein blood vessel are in simulation artery and vein blood vessel is installed reserved location;
Described simulate blood charge pump be responsible for to arteries blood supply and make artery in simulate blood circulating device and vein blood vessel on generate simulation pulse;
Described U-shaped connecting pipe two ends vary in size, and adapt to respectively the size of arteries and vein blood vessel, and U-shaped connecting pipe central through hole is little, and diameter is vein blood vessel diameter 1/5, to ensure that pulse can not be sent in vein blood vessel when blood is communicated with;
Described simulated skin is arranged on simulated skin reserved location is installed, and can be rotated;
One one-tenth human arm of internal arteriovenous fistula modeling, is mainly and carries out the design of internal arteriovenous fistula operative training.Model can simulate blood flow, can simulate arterial pulse, and skin can repeatedly use in the rotation of simulated skin reserved location place simultaneously, has saved material.In the time that needs are changed blood vessel, each simulation artery and simulation vein blood vessel that only needs to change operative segment, reduces spillage of material to greatest extent; Described simulated skin and simulated blood vessel are conveniently replaced simultaneously.

Embodiment
Internal arteriovenous fistula modeling arm 1 as shown in accompanying drawing 1, Fig. 2, Fig. 3, adopts harder plastics one-shot forming, simulation adult's arm.And on simulation arm 1, design in advance simulated skin reserved location 3 and simulation artery and vein blood vessel installation reserved location 2 are installed, simulate blood circulating device is placed in simulation arm, makes operative segment arteries 8, operative segment vein blood vessel 10 be in simulation artery and vein blood vessel installation reserved location 2 places.
Described simulate blood circulating device by simulate blood charge pump 5 by be communicated with communicating pipe 6 outer arteries blood vessel 7, afterwards by being communicated with operative segment arteries 8, the U-shaped connecting pipe 11 of rear connection, rear connection operative segment vein blood vessel 10 communicating pipe 6, afterwards by being communicated with outside vein blood vessel 9 communicating pipe 6, being communicated with simulate blood charge pump 5 by communicating pipe 6 afterwards, for simulate blood circulation, be placed in simulation arm 1, and operative segment arteries 8, operative segment vein blood vessel 10 are in simulation artery and vein blood vessel is installed reserved location 2.
Described simulate blood charge pump 5 be responsible for to arteries blood supply and make artery in simulate blood circulating device and vein blood vessel on generate simulation pulse;
Described U-shaped connecting pipe 11 two ends vary in size, and adapt to respectively the size of arteries and vein blood vessel, and U-shaped connecting pipe 11 central through holes are little, and diameter is vein blood vessel diameter 1/5, to ensure that pulse can not be sent in vein blood vessel when blood is communicated with;
Simulate blood charge pump 5 enters simulation blood pump in outer arteries blood vessel 7, operative segment arteries 8, making to form simulation pulse on the simulated blood vessel of simulate blood circulating device beats, medico is according to the requirement of internal fistula art, after cutting simulated skin 4, operative segment arteries 8, operative segment vein blood vessel 10 are done to a stitching, make the simulation arterial blood that flowing in the operative segment vein blood vessel 10 after coincideing, form an internal arteriovenous fistula.The blood vessel of internal arteriovenous fistula can provide sufficient blood for hemodialysis, for the adequacy of dialysis treatment provides safeguard.
When simulation artery and vein blood vessel install otch in the simulated skin of being made by resilient material 4 at reserved location 2 places too much, excessively random, can rotary simulation skin 4, make these otch avoid simulation artery and vein blood vessel installation reserved location 2, be changed to the position of the simulated skin 4 of not cutting, so that another medico trains, save material.Meanwhile, if when simulated skin 4 cannot be simulated the incision needs of internal fistula art, the simulated skin 4 that can more renew, facilitates multidigit medico repeatedly to train.
Sham operated part of arteries blood vessel 8 in internal fistula art and operative segment vein blood vessel 10 are by being communicated with outer arteries blood vessel 7 and outside vein blood vessel 9 communicating pipe 6, in the time that operative segment blood vessel damages, operative segment arteries 8 and operative segment vein blood vessel 10 can be only changed, material can be saved.
