Abstract
The utility model discloses the adjustable percussion hammer of a kind of hardness, relate to Neurology Department technical field of medical instruments, the percussion hammer that especially a kind of hardness is adjustable.It comprises handle, tup body, and tup body comprises rubber bag tank, circular base, and handle and circular base are fixed; Circular base and rubber bag tank are inlayed and are connected or are threaded; Magnetic flow liquid is filled with in rubber bag tank; The sidewall of rubber bag tank has been embedded in coil; Circular base internal fixtion has battery; Battery is electrically connected with coil by gauge tap; Gauge tap is installed on the end of handle.Hardness of the present utility model by changing the viscosity adjustment of magnetic flow liquid, can adapt to different percussion positions, facilitating the operation of medical worker.
Description
Technical field
This utility model relates to Neurology Department technical field of medical instruments, the percussion hammer that especially a kind of hardness is adjustable.
Background technology
Percussion hammer be doctor in order to check the utensil of neuromuscular reflex, handle mainly with one piece of rubber and a wooden or metal is formed.With rubber end knocking relevant portion gently during use, the neural reflex of patient is diagnosed to have accessible.
The body position checked is different, and the dynamics of percussion is not identical yet, and traditional percussion hammer hardness is fixing, and the dynamics very by knocking adjusts, higher to the requirement of medical worker like this, affects the diagnostic result of percussion, brings some inconvenience to medical work.
Utility model content
Technical problem to be solved in the utility model, be the technical deficiency for above-mentioned existence, provide a kind of hardness adjustable percussion hammer, its hardness can by changing the viscosity adjustment of magnetic flow liquid, different percussion positions can be adapted to, facilitate the operation of medical worker.
The technical solution adopted in the utility model is: provide a kind of hardness adjustable percussion hammer, and comprise handle, tup body, tup body comprises rubber bag tank, circular base, and handle and circular base are fixed; Circular base and rubber bag tank are inlayed and are connected or are threaded; Magnetic flow liquid is filled with in rubber bag tank; The sidewall of rubber bag tank has been embedded in coil; Circular base internal fixtion has battery; Battery is electrically connected with coil by gauge tap; Gauge tap is installed on the end of handle.
Further optimization the technical program, the tup body of the adjustable percussion hammer of hardness also comprises solid rubber tup, and solid rubber tup is positioned at circular base top and inlays with circular base and is connected or is threaded.
Further optimization the technical program, the handle of the adjustable percussion hammer of hardness is divided into two sections to be mutually socketed and the sleeve pipe be slidably matched in the longitudinal direction; Two sleeve pipes lock by automatic fastening.
The beneficial effects of the utility model are:
1, this utility model adopts magnetic flow liquid filled rubber capsule, the magnetic field intensity at magnetic flow liquid place is adjusted by the current intensity changing coil, thus changing the viscosity of magnetic flow liquid, after the viscosity-modifying of magnetic flow liquid, during rubber bag tank knocking patient body, hardness changes.
2, when battery electric quantity is inadequate, solid rubber tup can be adopted temporarily to replace, easy to use.
3, the adjustable length of handle, equally also can change the intensity of tup knocking.

Fig. 2 is the sectional view of this tup body.
In figure, 1, hands handle; 2, tup body; 3, rubber bag tank; 4, circular base; 5, magnetic flow liquid; 6, coil; 7, battery; 8, gauge tap; 9, solid rubber tup; 10, sleeve pipe; 11, automatic fastening.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As depicted in figs. 1 and 2, the adjustable percussion hammer of hardness, comprises handle 1, tup body 2, and tup body 2 comprises rubber bag tank 3, circular base 4, and handle 1 is fixed with circular base 4; Circular base 4 is inlayed with rubber bag tank 3 and is connected or is threaded; Magnetic flow liquid 5 is filled with in rubber bag tank 3; The sidewall of rubber bag tank 3 has been embedded in coil 6; Circular base 4 internal fixtion has battery 7; Battery 7 is electrically connected with coil 6 by gauge tap 8; Gauge tap 8 is installed on the end of handle 1; Tup body 2 also comprises solid rubber tup 9, and solid rubber tup 9 is positioned at circular base 4 top and inlays with circular base 4 and is connected or is threaded; Handle 1 is divided into two sections to be mutually socketed and the sleeve pipe 10 be slidably matched in the longitudinal direction; Two sleeve pipes 10 lock by automatic fastening 11.
Magnetic flow liquid (Magnetorheological Fluid is called for short MR fluid) belongs to controlled fluid, and magnetic flow liquid is by the suspended substance of high magnetic permeability, low hysteresis small soft magnetic particles and non-magnetic liquid mixing.This suspended substance presents low viscous Newtonian fluid characteristic under zero magnetic field condition; And under strong magnetic field action, then present the Bingham bulk properties of high viscosity, lazy flow.
Moment because the stream of magnetic flow liquid under the action of a magnetic field becomes, reversible and its stream become after shear yield strength and magnetic field intensity there is stable corresponding relation, be therefore a kind of intellectual material of of many uses, function admirable.Namely this utility model utilizes the characteristic of magnetic flow liquid viscosity B coefficent, is filled in rubber bag tank 3, is changed the hardness of rubber bag tank 3, thus adapt to the different rapping intensity of diverse location by adjustment magnetic field intensity.
Gauge tap 8 adopts sliding rheostat switch, and namely the position of slide switch can open and adjust the current intensity of coil 6.Can be felt by finger pressure rubber bag tank 3 and the viscosity of magnetic flow liquid 5 judge the hardness of rubber bag tank 3.
