Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a marrow quantitative puncture needle.
Background
The marrow puncture needle is a common diagnostic technique for collecting marrow fluid, the clinical marrow puncture fluid is usually used for blood cell morphology examination, hematopoietic stem cell culture, cytogenetic analysis, pathogenic biology examination and the like, when the clinical diagnosis of blood system diseases is confirmed, the marrow puncture is the most important and basic examination item, the purpose of a marrow cell smear is to judge the proliferation degree of nucleated cells and calculate the percentage, the form, the quantity and the distribution condition of various cells, and the marrow puncture sucks the marrow fluid, so that the marrow puncture needle is a traumatic examination means and is usually completed by two steps of puncture first and suction later. Bone marrow pjncture needle that uses at present, constitute including tube-shape syringe needle, syringe needle seat and nook closing member, the nook closing member is solid needle bar, and the syringe needle is the inclined plane, and the dress is in the tube-shape syringe needle, and the inclined plane of nook closing member point portion flushes with the bevel connection face of tube-shape syringe needle, and the not good ration of current technique, two circumstances can appear when medical personnel operate: firstly, too much effort is exerted on medical care personnel, so that more bone marrow fluid is extracted, and the bone marrow fluid is easily diluted during extraction; the second medical personnel make the marrow liquid of taking out less with strength for medical personnel need carry out extraction many times, and the extraction increases unnecessary trouble easily many times, and makes the bone fragment pile up the pinhole easily when extracting the marrow liquid and lead to the extraction that can't carry out the marrow liquid. The marrow extraction amount of the bone marrow liquid extracted by the medical staff is 0.1ml to 0.2ml, which causes that the medical staff is not good to quantify the bone marrow liquid, so that repeated extraction is needed to reach the level line of the extracted bone marrow liquid.
SUMMERY OF THE UTILITY MODEL
The utility model provides a bone marrow puncture injector, which solves the problem that medical staff need to extract repeatedly in the prior art.
The utility model provides a marrow puncture syringe, includes the syringe, the syringe includes barrel and the piston that slides in the barrel, the piston includes mobile jib and chock plug, cavity is provided with logical groove in the mobile jib, set up the through-hole that switches on with logical groove and make the inside and outside gas pocket that switches on of barrel on the chock plug, it slides along length direction and is provided with the auxiliary rod to lead to the inslot, the outside extension of auxiliary rod one end to the barrel is provided with the handle, and the other end is worn out the through-hole and is provided with the supplementary stopper that is used for shielding through-hole and gas pocket, the auxiliary rod slides in logical inslot and realizes shielding or exposing of supplementary.
The technical scheme is adopted, and the method has the advantages that: an auxiliary rod is slidably arranged in the through groove, medical staff operates the auxiliary rod to move downwards through a handle to enable the auxiliary plug to remove the shielding of the air hole and the through hole, the air pressure inside and outside the cylinder body is the same, so that the medical staff can operate the piston to move downwards again, and the phenomenon that the medical staff shakes the marrow puncture needle when taking off the injector due to the touch is avoided; medical personnel shift up through the handle operation auxiliary rod and make supplementary stopper realize shielding to gas pocket and through-hole, and the inside and outside atmospheric pressure difference of barrel makes medical personnel can carry out repeated extraction and can not influence the marrow pjncture needle, and when the gas pocket was opened, the gaseous meeting in the extraction storehouse can be followed outside the syringe of discharging in the gas pocket for thereby bone marrow liquid can not receive when the mobile jib moves down and influence the emergence and leak the scheduling problem, follow the utility model discloses simple structure, it is portable to operate, has improved operation efficiency.
The utility model discloses further set up: the auxiliary plug is provided with a plug-in connector in an extending mode corresponding to the air hole, and the plug-in connector is in plug-in fit with the air hole to block the air hole.
The technical scheme is adopted, and the method has the advantages that: the plug-in connector is plugged and matched with the air hole to block the air hole, so that the air pressure in the barrel is more stable, and medical personnel can extract bone marrow liquid more stably.
The utility model discloses further set up: the air holes are arranged in a conical shape.
The technical scheme is adopted, and the method has the advantages that: the air hole is arranged in a conical shape, so that the plug connector is in close plug fit with the air hole.
The utility model discloses further set up: scales are carved on the outer wall of the cylinder body along the length direction of the cylinder body.
The technical scheme is adopted, and the method has the advantages that: the setting of scale makes medical personnel can the audio-visual judgement bone marrow liquid volume.
The utility model discloses further set up: still be provided with the filter screen in the barrel, the filter screen is close to barrel injection end and sets up.
The technical scheme is adopted, and the method has the advantages that: the filter screen is arranged in the cylinder body to prevent bone fragments from entering when bone marrow liquid is extracted.
