Description

A kind of apparatus and method of setting up the bone marrow fluid path
Technical field
The present invention relates to a kind of bone marrow fluid path of setting up and also realize the alternative apparatus and method of liquid through this path.
Background technology
Intravenous drug, blood transfusion and fluid infusion etc. are one of the most basic means of the anxious heavy patient of treatment.But, often set up the transfusion path and be difficult to successfully through venipuncture for extreme dehydration, serious shock and fat especially critical patient.Can only take the way of venotomy to accomplish, but the venotomy operating difficulties, lose time, wound is obvious.Can't set up unobstructed infusion channel fast, with the rescue that has a strong impact on the critical patient.
Medullary cavity links to each other with the human recycle system closely, can be regarded as the indirect venous transfusion path that never subsides fully, carries out infused drug and blood through medullary cavity, will great help be provided for rescuing critical patients such as severe shock.
Can extracting bone marrow fluid out, to carry out Clinical Laboratory also be clinical common diagnosis and treatment means with extracting that marrow stem carefully runs etc., correctly diagnose and extract qualified bone marrow stem cell, often depends on the situation of the path of extracting bone marrow fluid out.
Traditional bone marrow aspiration, more owing to the operation difficult point, specification requirement is higher, subjective influence is big and the reason such as long that expends time in, can't be applicable to critical patients such as severe shocks and set up the transfusion path.Also there are inconvenient operation, the unfavorable problem of effect when extracting bone marrow fluid with traditional method simultaneously.
Through a kind of advanced person's new equipment, set up the fluid path of medullary cavity quickly and easily, can guarantee that liquid injects medullary cavity fast; And then inflow vein; Accomplish tasks such as rescue, can realize the accurate extraction of bone marrow fluid again, accomplish tasks such as accurately diagnosis and extraction bone marrow stem cell.
Summary of the invention
The objective of the invention is to provide a kind of device of simply setting up the bone marrow fluid path fast, can forming easily through this device, liquid injects the new method of extracting out with accurate liquid.
The objective of the invention is to realize like this, this device comprises regulating sleeve, is arranged on the retainer of regulating sleeve inner chamber; Be arranged in the regulating sleeve inner chamber, the broach assembly between retainer and the push rod, be set in the depression of push rod through steady pin, be with the collet of back-up ring on it, be connected the sleeve pipe of regulating sleeve one end; Be arranged on push rod and spring in the sleeve pipe, be sleeved on the sliding sleeve on the sleeve outer wall, be arranged on the bonnet of sleeve pipe one end; Be inserted in the safety plug on sliding sleeve and the sleeve pipe; Annular groove is arranged on the push rod, passage is arranged on the regulating sleeve, there is the annular step tread regulating sleeve inside.
Described broach assembly comprises syringe needle, is arranged on the nook closing member in the syringe needle, is arranged on the needle holder of syringe needle one end, is plugged on the needle core base of needle holder one side, connection nook closing member; Wherein needle holder has annular groove and groove; The syringe needle left end has the micropore perpendicular to its axis in addition; Convexity is arranged on the needle core base.
A kind of method of setting up the bone marrow fluid path, this method may further comprise the steps:
1., regulating sleeve is threadedly connected to sleeve pipe one end, change regulating sleeve and telescopic relative position, thereby change the relative position of the left side relative bone broach assembly of regulating sleeve through rotary regulating sleeve, and then the adjustment broach assembly degree of depth of injecting.
2., collet is fixed on through steady pin in the depression of push rod, shield ring sleeve is in the outside of collet, and back-up ring is moved to the left collet is tightened, thereby clamps the annular groove of broach assembly; Retainer is installed in the syringe needle outside of broach assembly, is used to support the broach assembly, makes not deflection of its center that is in regulating sleeve.
3., extract safety plug on sliding sleeve and the sleeve pipe; Spur sliding sleeve to the right, remove of the constraint of two elastic card claws, make push rod under the effect of spring push rod; Promoting the broach assembly is moved to the left, injects in the medullary cavity fast; This moment, back-up ring relative resilient chuck under the promotion of regulating sleeve inner ring type cascaded surface moved right, and made the collet expansion, and with the broach components apart.
4., remove this device, extract nook closing member and needle core base, external medical pipeline on needle holder can the required liquid of infusion also can extract bone marrow fluid.
Liquid of the present invention is meant the various liquid that bone marrow exchanges (injecting or/and extract out) that are suitable for, as: medicinal liquid, blood and bone marrow fluid etc.
The present invention has the following advantages and effect:
1, simple success easily rapidly
Traditional bone marrow aspiration is the hand-held medullo-puncture needle of operator, firmly thrusts in patient's the medullary cavity.But the operator will do one's utmost to use operation skill, control firmly size, assurance inserting needle direction and the degree of depth etc., complicated operation, and difficulty is bigger, easily failure.Use this device then different, puncture dynamics and the degree of depth are that machinery is set and regulated, and only need the operator that this device is placed on the selected point of puncture, take off safety plug, the pulling sliding sleeve can be accomplished puncture, and join dependency medical treatment pipeline is accomplished all and operated again.Whole process is simple especially, laborsaving, quick, easily success.
2, changing tradition looks for another way
Traditional bone marrow aspiration is generally selected patient's positions such as anterior superior iliac spine, posterior superior iliac spine and breastbone, but these positions are not suitable for keeping somewhere syringe needle, should not be as the bone marrow fluid path,
Transfuse blood, fluid infusion and injectable drug etc., just be not suitable for critical patient's rescue yet.And be convenient to the position of keeping somewhere syringe needle, setting up the bone marrow fluid path, like tibia and upper end of humerus etc. because sclerotin is comparatively fine and close, with hands difficulty thrust, traditional bone marrow aspiration is difficult to successfully.Use this device then greatly to take on a new look; Can be as required and objective circumstances; Select optimal site---carry out bone marrow aspiration like positions such as tibia upper ends; All bring great convenience for work such as setting up bone marrow fluid path, the nursing of indwelling syringe needle, blood transfusion fluid infusion and medicine injection, also better choice is provided to bone marrow extraction check and bone marrow stem cell.
3, the first aid innovation is safe and reliable
Because this device can be simply, fast, convenient, successfully set up indirect venous access, will great facility be provided for critical patients such as rescue severe shocks, strive for valuable time, obviously improve salvage success rate.Be specially adapted to critical patient's under the arduous environment such as earthquake, tsunami, war and the scene of the accident first aid.Carry out clinically in addition in the cardio-pulmonary resuscitation, intra-bone marrow injection can replace injection in the chambers of the heart fully, and is same effective rapidly, but damage is slight, and this new method will be popularized in an all-round way in various first aids and popularize.
