The medical science emulation arm
Technical field
The utility model relates to a kind of teaching simulation utensil, especially relates to a kind of medical science emulation arm.
Background technology
Venous transfusion injection is a medical nursing specialty and from doctor's basic training, requires action accurately, is skilled in technique, but owing to can not do the limitation of acupuncture exercise the living person on one's body, and this is for the beginner, has just become to be difficult for the obstacle gone beyond together.For this reason, the simulation arm has just become best teaching appliance.The transfusion arm that existing more domestic producers make, its structure are that the inside is the plastics hearts, outside cover last layer rubber epidermis, both middle blood vessels that add rubber.Its weak point is that technology is coarse, and outward appearance does not resemble really, and feel is bad, and the free sense of skin is not enough, and blank sense is not obvious, and can only be in the ancon injection of part.
Summary of the invention
In order to overcome the unlifelike problem of existing simulation arm, provide a kind of walk back and forth very effective, but injection for intravenous, storage blood and intramuscular injection exercise, long service life, emulation arm simple in structure are the purpose of this utility model.
Technical solution adopted in the utility model is: mainly be made of epidermis, blood vessel, carcass, it is characterized in that being furnished with on the epidermis blood vessel protuberance of trickle skin line and emulation, carcass has the blood vessel groove, blood vessel places in the blood vessel groove corresponding with the epidermis blood vessel, veins beneath the skin and anatomy basically identical, make emulation arm the same with true man's arm, very true to nature.In epidermis, increased the nylon guard in addition, made epidermis more firm, can use repeatedly; Arm is provided with storage blood bag outward, is connected with blood vessel by interface, can do the injection exercise on full arm; The thickness of epidermis is 0.01-0.05mm, and its thickness of different parts is inequality, makes function more obvious.
The beneficial effects of the utility model are: skin line and blood vessel are arranged in appearance, lifelike image, the same with true man's arm, and blood vessel places in the blood vessel groove, and with the anatomy basically identical, the free sense of skin is good and blank sense is obvious, storage blood bag is connected with blood vessel, owing to add the nylon guard in the epidermis, be difficult for stabbing out long service life.Can carry out various injection exercises at complete all angiosomeses of arm, and can do artery and vein, puncture transfusion and intramuscular injection on emulation arm, having overcome existing product can only do intravenous limitation at ancon, and blood vessel and epidermis also can be changed repeatedly.
Description of drawings
Accompanying drawing is a medical science emulation arm structural representation of the present utility model.
Among the figure: 1, arm; 2, epidermis; 21, skin line; 22, nylon guard; 3, blood vessel; 4, carcass; 5, storage blood bag.
Embodiment
Further specify as follows below in conjunction with drawings and Examples:
Referring to accompanying drawing, the softer latex material of carcass 4 usefulness is made, and is provided with the blood vessel groove.Blood vessel 3 usefulness high-tension latexes or silica gel are made, and place in the blood vessel groove, and an end of blood vessel 3 and storage blood bag 5 are connected by interface; In order to strengthen the serviceable life of epidermis 2, in epidermis, added nylon guard 22, on epidermis 2, there is the same skin line 21 of emulation corresponding with blood vessel 3 with the blood vessel protuberance.
During injection, storage blood bag 5 places higher position, and when the accurate letter of pin was gone into blood vessel, the blood of storage blood bag 5 flows to entry needle by interface intravascular 3 and produces blood back, and was very true to nature.
Epidermis 2 thickness are 0.01-0.05mm, in the different parts thickening, make different parts thickness inequality, and good hand touch is durable again.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
