Before the present utility model, traditional old-fashioned marrow cavity puncture infusion set, how due to needs manual feed, manual operation effort is consuming time, technical requirement is high, body is heavyly difficult to carry, expensive, puncture needle lacks and the latter linked puncture needle that punctures easily stops up etc., bring inconvenience to clinical use, be difficult to complete within the prime time of rescuing, have a strong impact on rescue process, bring life danger to patient.
Summary of the invention
The purpose of this utility model is just to overcome above-mentioned defect, develops a kind of bone marrow aspiration rifle with anti-blockage function.
The technical solution of the utility model is:
A kind of bone marrow aspiration rifle with anti-blockage function, rifle body front end is rifle head end, bayonet socket is connected on bayonet socket dish, bayonet socket dish is connected on rifle head end, the bayonet socket end of bayonet socket dish connects nook closing member, rifle body tail end connecting handle, its technical characteristics is that rifle head end connects rifle body, electric magnet in rifle intracoelomic cavity, electric switch is positive and negative polarities, lay respectively at the rear and front end of rifle intracoelomic cavity, blade is connected on piston, piston is placed in the middle of solenoid, piston is made up of magnetic material, electric magnet is anterior and be centered around around blade front portion at rifle intracoelomic cavity, one end, conducting wire connects the electric magnet in rifle intracoelomic cavity, the other end connects power supply, trigger is arranged on conducting wire, electric switch is arranged on piston working line, connection conducting wire, electric switch one end, the other end connects positive source or negative pole.
On bayonet socket dish on described rifle head end, actuator is set.
Described trigger is arranged on handle.
Charging hole is set on described handle.
The present invention has the following advantages and effect: bone marrow aspiration rifle is without selecting distinctive puncture needle, can regulate according to the puncture needle that had at one's side, adjust puncture nook closing member length, penetrate after medullary cavity together with puncture needle, without extra flushing, along the logical path etc. that punctures, pull out after puncture rifle and puncture nook closing member, just can directly connect transfusion path, the administration of being infused.
That this utility model also has is simple in structure, easy to operate, laborsaving, save time, be easy to carry; Operate smooth and easyly, without worrying the situations such as puncture needle kind, puncture needle obstruction, ensured marrow cavity puncture safety in place, effectiveness, striven for prime time for rescuing life.
Brief description of the drawings
Fig. 1---this utility model vertical section structure principle schematic.
In figure, each label represents that corresponding component names is as follows:
Rifle body 1, rifle head end 2, bayonet socket 3, bayonet socket dish 4, nook closing member 5, actuator 6, connection tube 7, blade 8, piston 9, solenoid 10, electric magnet 11, conducting wire 12, electric switch 13, trigger 14, handle 15, power supply 16, charging hole 17.
Detailed description of the invention
As shown in Figure 1:
(puncture) rifle body 1 front end is rifle head end 2, bayonet socket 3 can regulate according to different puncture needle sizes, bayonet socket 3 connects on bayonet socket dish 4, bayonet socket dish 4 is connected on rifle head end 2, bayonet socket dish 4 is provided with nook closing member 5, nook closing member 5 passes through from bayonet socket 3 centers, actuator 6 is arranged on rifle head end 2 sides, scalable nook closing member 5 exposes or stretches out the length of the part of bayonet socket 3, rifle head end 2 is connected with rifle body 1 by (elasticity) connection tube 7, rifle body 1 inner chamber is provided with blade 8, (magnetic) piston 9, solenoid 10, electric magnet 11, conducting wire 12, electric switch 13, electric magnet 11 is positive and negative polarities with electric switch 13, lay respectively at rifle body 1 inner chamber before, rear two ends, blade 8 is connected with piston 9, piston 9 is made up of magnetic material, be placed in the middle of solenoid 10, electric magnet 11 is anterior and be centered around around blade 8 front portions at rifle body 1 inner chamber, 12 one end, conducting wire connect the electric magnet 11 in rifle body 1 inner chamber, the other end connects power supply 16, trigger 14 is arranged on the conducting wire 12 between electric magnet 11 and power supply 16, electric switch 13 one end are arranged on piston 9 working lines, electric switch 13 connection conducting wires, one end 12 (electric magnet 11), the other end connects power supply 16 negative or positive electrodes, rifle body 1 tail end is handle 15, and trigger 14, on handle 15, also arranges charging hole 17 on handle 15.
The explanation of this utility model application process:
In the time carrying out marrow cavity puncture, can clamp puncture needle nook closing member 5 with bayonet socket 3 according to puncture needle size for subsequent use at one's side, be arranged on actuator 6 on rifle head end 2 sides by adjusting, regulate nook closing member 5 through puncture needle, and make nook closing member 5 be slightly shorter than puncture needle head end, puncture needle nook closing member 5 is aimed to the position of sterilization of wish puncture medullary cavity.Switch on power 16, hold handle 15, now conducting wire 12 access failure, cocking 14, conducting wire 12 is connected, power supply 16 (supposing it is negative pole) electric current is by solenoid 10, power supply 16 (supposing it is anodal) electric magnet 11, solenoid 10 energisings make the piston 9 of being made up of magnetic material produce magnetic force, the electromagnetic field that electric magnet 11 energisings produce is contrary with piston 9 magnetic, so attract each other, thereby piston 9 is pulled to a left side from the right side, piston 9 ejects (in figure for from right to left) to rifle head end 2, blade 8 is connected on piston 9 front ends, so blade 8 can contact with the bayonet socket dish 4 on rifle head end 2, just puncture needle nook closing member 5 can be advanced in medullary cavity with sudden force together with bayonet socket 3.In rifle body 1 bottom, in the time that piston 9 (in figure for from right to left) is mobile, can bump against the electric switch 13 being arranged on piston 9 working lines, thereby make electric switch 13 disconnect original connection circuit, connect another circuit by conducting wire 12, and this circuit is just in time to provide and original contrary electric current to electric magnet 11, thereby making piston 9 stop forward (left side) moves, and because same and mutually exclusive with electric magnet 11 Magnetic Phases, piston 9 is moved right on the contrary, and puncture needle and nook closing member 5 exit.Penetrating medullary cavity at puncture needle has when sense of falling through, and bone marrow aspiration rifle body up slightly can be carried, and guarantees that the medullary cavity of puncture needle is in place.Spiral bayonet socket 3 is unclamped, exit puncture nook closing member 5, puncture needle can directly connect transfusion device, and life is rescued in the administration of being infused.
Once electricity is finished, can charge by the charging hole 17 on handle 15.
