Simulator for medical training with detachable self-sealing hollow member
Simulator for medical training having at least a detachable, fluid-tight hollow member comprising: at least a portion ( 1; 25 ) made of a self-sealing material; an opening ( 2; 17 ) to fill said hollow member with a fluid, said opening ( 2, 17 ) being provided with closure means ( 4; 26 ) or being connected ( 8 ) to closure means; fastening means ( 4,5; 28 ) to detachably fasten said hollow member to said simulator. The portion made of self-sealing material allows multiple punctures before having to be replaced.
1. Simulator for medical training having at least a detachable, fluid-tight hollow member, said hollow member being characterized by comprising:
a) at least a portion made of a self-sealing material;
b) an opening to fill said hollow member with a fluid, said opening being provided with closure means or being connected to closure means;
c) fastening means to detachably fasten said hollow member to said simulator;
wherein said self-sealing material fulfills a test in which a fluid-tight hollow member having a wall thickness of 2.5 mm, inflated to apply an initial pressure of 500 mbar, undergoes a pressure drop after 60 seconds to not less than 50 mbar caused by 10 punctures made by a needle having a gauge size of 16 G.
2. Simulator according to claim 1 , characterized in that said self-sealing material is a synthetic polymer selected from the group consisting of thermoplastic elastomers, silicone rubber, synthetic rubber, polyolefins, polyurethanes, polytetrafluoroethylene.
3. Simulator according to claim 1 , characterized in that said self-sealing material is a styrene-ethylene-butadiene-styrene (SEBS) copolymer.
4. Simulator according to claim 1 , characterized in that said portion made of a self-sealing material has the form of a bladder having an opening provided with closure means formed by a nipple part connected via a tube to remote closure means.
5. Simulator according to claim 4 , characterized in that said fastening means comprise an assembly formed by said nipple part and a clamp ring inserted onto said nipple part, said assembly being fastened to said simulator by a support plate.
6. Simulator according to claim 4 , characterized in that said fastening means comprise an assembly formed by said nipple part and a clamp ring inserted onto said nipple part, said assembly being housed in a recess of said simulator and being fastened to said simulator by a support plate overlapping at least partially said recess.
7. Simulator according to claim 1 , characterized in that said portion made of a self-sealing material has the form of a tubular member having an opening provided with closure means formed by a cap.
8. Simulator according to claim 7 , characterized in that said fastening means comprise a cover member having on one side a cavity that matches the shape and size of said tubular member, whereby said tubular member and cover member may be fastened in a corresponding cavity of said simulator.
9. Simulator according to claim 7 , characterized in that said cover member is made of a material having bone-like properties.
10. Simulator according to claim 1 , characterized in that said hollow member comprises means to connect sensors to measure parameters relating to the fluid contained in said hollow member.
11. Simulator according to claim 1 , characterized in that said hollow member comprises connection means to supply and/or withdraw fluid to/from said hollow member.
12. Simulator according to claim 1 , characterized by comprising at least a recess in which said hollow member is arranged and kept in position by said fastening means.
