Embodiment 1

[0027] see Figure 1-3 , a puncture device for hematology bone marrow treatment, comprising a tube body 10, a needle 16, and a bone marrow fluid tank 19; The lower side of the pipe body 10 is fixedly fitted with a mounting ring, and the lower surface of the mounting ring is fixedly installed with three sets of inclined telescopic brackets 14 at equal intervals. The telescopic bracket 14 is composed of a telescopic rod, a sleeve, and a tightening bolt. At the bottom of the ring, the telescopic rod is telescopically connected inside the sleeve, and the lower side wall of the sleeve is provided with tightening bolts for controlling the movement of the telescopic rod inside the sleeve. By setting the telescopic bracket 14 and placing its bottom on the limb to be punctured, a stable supporting force is provided for the entire tubular body 10 , thereby maintaining the stability of the tubular body 10 in use. The bottom of the telescopic bracket 14 is fixedly equipped with a suction...

Embodiment 2

[0030] On the basis of embodiment one, be positioned at the left side wall of the tube body 10 on the upper side of the disinfection sponge 28 and the left and right side walls of the tube body 10 on the lower side of the disinfection sponge 28 all according to the ultraviolet cavity 25, the outer side of the ultraviolet cavity 25 is set It is a glass transparent structure, and the inside of the ultraviolet cavity 25 is fixedly provided with an ultraviolet lamp 26, and the needle tube and the needle head 16 received into the tube body 10 can be sterilized by light by activating the ultraviolet lamp 26.

[0031] The working principle of the present invention is: when in use, first press the pressing plate 13 downward so that the piston 23 is at the bottom of the piston chamber 22, then the operator needle 16 is facing the position to be punctured, and then the needle 16 is moved by the telescopic bracket 14 Fix it, and then push down the slide block 18 to slide down in the slide...

Abstract

The invention relates to the technical field of medical equipment, and discloses a puncture device for bone marrow treatment in the hematology department. The device comprises a pipe body, a needle head and a bone marrow fluid box; three groups of inclined telescopic brackets are fixedly mounted on the lower surface of a mounting ring at equal intervals, a group of piston cavities are formed in the inner top of the pipe body, the bottom of each piston cavity communicates with a telescopic pipe arranged on the upper side of the middle in the pipe body, the bottom of the telescopic pipe communicates with a needle pipe, the bottom end of the needle pipe penetrates through the lower side wall of the pipe body and outwards communicates with the needle head, the middle of the needle pipe is fixedly sleeved with a set of sleeve blocks, sliding blocks are fixedly installed on the right sides of the sleeve blocks through threaded rods, and the lower portion of the right side wall of the telescopic pipe rightwards communicates with an infusion pipe extending out of the pipe body; and a group of disinfection sponge with a circular ring-shaped structure is arranged in the pipe body positionedat the middle lower part of the needle pipe, and a vertical sliding opening is formed in the right side of the disinfection sponge. The device has the advantages of simple operation, high stability, low use cost, and convenient cleaning and disinfection.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a puncture device for hematology bone marrow treatment. Background technique [0002] Bone marrow aspiration is to insert a puncture needle into the patient's bone marrow, and then extract the bone marrow. The extracted bone marrow needs to be quickly smeared for testing. Traditional bone marrow extraction involves inserting a needle into the patient's bone marrow, and then extracting a certain amount of bone marrow with a syringe. The aspirated bone marrow was spread on a glass slide. [0003] Chinese patent (notification number: CN 205548592 U) discloses a hematology bone marrow puncture device, including a needle, a connector, a first one-way valve, a suction tube, an induction switch, an air pump, a smear tube, and a second one-way valve , the hematology bone marrow puncture device first inserts the needle into the patient's bone marrow, starts the air pump, and th...
