Abstract
The utility model relates to an extract pleural cavity negative pressure puncture ware of hydrops in patient's pleural cavity, the both ends that its characterized in that middle section suit had the transparent hose of infusion throttle clamp are respectively through tubulose articulate pjncture needle, and one of them pjncture needle inserts in the negative pressure glass bottle through the rubber sealing plug that is located the negative pressure glass bottleneck. The doctor inserts another disinfected puncture needle into the pleural cavity of the patient slowly, opens the transfusion throttle clamp, and stops the needle insertion when the effusion automatically flows into the negative pressure glass bottle through the transparent hose. The utility model has the advantages of safety, reliability, convenient operation, simple structure, clinical practicality and good effect.
Description
This utility model relates to medical apparatus and instruments, especially the intrapleural negative pressure perforator of the hydrops in a kind of patient's of extraction pleural space.
Clinically at present, extract hydrops in patient's pleural space and be earlier puncture needle, puncture to patient's pleural space with the rubber hose of the useful hemostatic clamp jaw seals of terminal cover, after estimating that by rule of thumb syringe needle inserts in the pleural space, the other end with rubber hose links to each other with syringe again.Open the hemostasis clamp of clamping rubber hose, slowly spur piston,, do not see the hydrops extraction, then will adjust the insertion depth of puncture needle repeatedly, until extracting hydrops out if syringe needle does not put in place.The operation more complicated requires the doctor to have higher operating technology and rich experience.
Task of the present utility model provides a kind of intrapleural negative pressure perforator of safe and reliable, easy to operate, simple in structure, clinical practice.
The technical solution of the utility model is: at the stage casing suit two ends of transparent hose of pinchcock, connect puncture needle by tubular configured joint respectively, a root puncture pin wherein inserts by the rubber seal plug that is positioned at the negative pressure glass bottle opening and has been pumped into the negative pressure vial of vacuum.Interface between above-mentioned each other part is and is tightly connected.Volume in the transparent hose is less than volumetrical 1/3 in the negative pressure vial.
Owing to adopted technique scheme, during hydrops specimen in gathering patient's pleural space, do not need to adopt syringe manually to extract, but draw automatically by the negative pressure vial.The doctor will be disinfectant puncture cushion to patient's pleural space, when syringe needle enter subcutaneous after, open the pinchcock of the tight closed condition in original place immediately fully and continue inserting needle, have hydrops to flow out as from transparent hose, seeing, just can stop inserting needle.Therefore the doctor can judge timely, objective, exactly whether puncture needle puts in place, does not need to try to take out, explore repeatedly as old-fashioned method the insertion depth of syringe needle, will cause adverse consequencess such as pneumothorax, hemothorax because of inserting deeply.The utlity model has advantages such as safe and reliable, easy to operate, simple in structure, clinical practice, effect be good.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is a structure principle chart of the present utility model.
In the accompanying drawings, the two ends of transparent hose (4) are connected with puncture needle (6) by used pleural space puncture needle (1) in tubular configured joint (2) and the hospital respectively.Puncture needle (6) inserts negative pressure vial (7) by the rubber seal plug (5) that is positioned at the negative pressure glass bottle opening.Puncture needle (1), puncture needle (6), tubular configured joint (2), transparent hose (4), rubber seal plug (5) and negative pressure vial (7), the interface between is and is tightly connected mutually.Stage casing in transparent hose (4), suit used infusion pinch cock (3) in the hospital.When puncture needle (6) was inserted rubber seal plug (5), pinchcock (3) should be in tight closed condition, to guarantee the vacuum in the negative pressure vial (7).
During clinical practice, the doctor will be disinfectant puncture needle (1) slowly insert pleural space to the patient, when syringe needle enter subcutaneous after, open the pinchcock (3) of the tight closed condition in original place immediately fully and continue inserting needle, there is hydrops to flow out as from transparent hose (4), seeing, just can stop inserting needle.Because the hydrops in the negative-pressure sucking in the negative pressure vial (7), patient's pleural space flows in the negative pressure vial (7) automatically.In order to guarantee enough negative-pressure suckings, the volume in the transparent hose (4) should be less than volumetrical 1/3 in the negative pressure vial (7).One bottled full after, can close pinchcock (3), extract puncture needle (6) out, change another negative pressure vial or syringe, continue to extract in the pleural space hydrops or to the intrapleural injection medicine.
Claims (3)
1. intrapleural negative pressure perforator, it is characterized in that: at the stage casing suit two ends of transparent hose (4) of pinchcock (3), connect puncture needle (1) and puncture needle (6) by tubular configured joint (2) respectively, puncture needle (6) inserts negative pressure vial (7) by the rubber seal plug (5) that is positioned at the negative pressure glass bottle opening.
2. intrapleural negative pressure perforator according to claim 1, it is characterized in that: puncture needle (1), puncture needle (6), tubular configured joint (2), transparent hose (4), rubber seal plug (5) and negative pressure vial (7), the interface between is and is tightly connected mutually.
3. intrapleural negative pressure perforator according to claim 1 is characterized in that: the volume in the transparent hose (4), and less than volumetrical 1/3 in the negative pressure vial (7).
