Abstract

The utility model relates to a thoracocentesis instrument which comprises a puncture needle, wherein a suction conduit and an injection syringe are communicated with the rear end of the puncture needle in turn; a piston is arranged in the injection syringe; a piston rod and a handle are connected with the rear end of the piston in turn; a branch pipe communicated with an inner cavity of the injection syringe is arranged on a lower side wall of the middle rear part of the injection syringe; a volumetric flask is communicated with the lower end of the branch pipe; and check valves are respectively arranged on the suction conduit and the piston. The thoracocentesis instrument can extract any quantity of pleural effusion by once puncturing according to the requirement; the thoracocentesis instrument is conveniently operated and used; and the complex puncturing process is reduced.

Description

A kind of thoracic puncture set

Technical field

This utility model relates to the cardiothoracic surgery technical field of medical instruments, relates in particular to a kind of thoracic puncture set.

Background technology

Thoracic puncture set is the medical apparatus and instruments of often using in the cardiac thoracic surgery, and it utilizes the negative pressure in the syringe successfully hydrops in the torso model or gas to be extracted out through puncture needle is thrust torso model then; In diseases such as treatment pneumothorax or pleural effusion, good effect is arranged, but there is a problem in this common perforator: when the intravital hydrops of people or gas more after a little while, utilize this perforator to extract and once can accomplish; But hydrops that need extract or gas are more for a long time; Must repeated multiple times extract, must puncture needle be pulled out each time, pour out liquid in the syringe; Extract then next time; So operation is very loaded down with trivial details, has not only increased patient's misery, has also increased the weight of medical personnel's working strength.

The utility model content

This utility model technical problem to be solved is: overcome existing puncture needle defective; A kind of thoracic puncture set is provided; This perforator needn't pull out puncture needle when using repeatedly can be clean with hydrops in the torso model or gas extraction; Thereby reduce the patient suffering, alleviate medical personnel's working strength.

The technical scheme of this utility model is: a kind of thoracic puncture set; Comprise puncture needle; Said puncture needle rear end is communicated with suction catheter, syringe cylinder successively, and piston is arranged in the syringe, and piston rear end connects piston rod, handle successively; It is characterized in that: the arm of a connection syringe inner chamber is arranged on the postmedian position lower wall of said syringe, and the arm lower end is communicated with a volumetric flask; Be respectively equipped with check valve on the said suction catheter and on the piston.

Said puncture needle rear end is fixed with the sucker of adsorbable human body skin.

During work, owing on suction catheter and piston, be provided with check valve respectively, then when the pulling piston; The suction check valve is open-minded, can guarantee the hydrops in the torso model or gas extraction in syringe, when piston is drawn to the arm rear; Liquid in the syringe can fall under gravity in the volumetric flask, shifts piston onto origin-location then, at this moment; Because the effect of check valve, the gas in the syringe can rearward be discharged from piston, and the liquid that can not in the suction catheter refluxes along piercing needle.Carrying out next circulation continuation extraction pleural fluid then, repeated multiple times extracts hydrops so as required.

Fixedly install the sucker of adsorbable human body skin in the puncture needle rear end, the adsorption of sucker capable of using is the puncture needle relative fixed, avoided that puncture needle comes off from human body in the operation process.

A kind of thoracic puncture set of this utility model is simple in structure, can accomplish that one-time puncture as required just can extract the hydrothorax of any amount.Easy for operation, reduced the puncture complicated processes.

Description of drawings

Below in conjunction with accompanying drawing and embodiment this utility model is described further.

Accompanying drawing 1 is the structural representation of this utility model embodiment.

Among the figure, 1. puncture needle, 2. sucker; 3. suction catheter, 4. check valve, 5. piston, 6. syringe, 7. arm, 8. handle, 9. volumetric flask.

The specific embodiment

A kind of thoracic puncture set; Comprise puncture needle 1; Said puncture needle 1 rear end is communicated with suction catheter 3, syringe 6 successively, and piston 5 is arranged in the syringe 6, and piston 5 rear ends connect piston rod, handle 8 successively; The arm 7 of one connection syringe inner chamber is arranged on the postmedian position lower wall of said syringe 6, and arm 7 lower ends are communicated with a volumetric flask 9; Be respectively equipped with check valve 4 on the said suction catheter 3 and on the piston 5; Said puncture needle 1 rear end is fixed with the sucker 2 of adsorbable human body skin.

Claims

1. thoracic puncture set; Comprise puncture needle; Said puncture needle rear end is communicated with suction catheter, syringe cylinder successively, and piston is arranged in the syringe, and piston rear end connects piston rod, handle successively; It is characterized in that: the arm of a connection syringe inner chamber is arranged on the postmedian position lower wall of said syringe, and the arm lower end is communicated with a volumetric flask; Be respectively equipped with check valve on the said suction catheter and on the piston.

2. like the described a kind of thoracic puncture set of claim 1, it is characterized in that: said puncture needle rear end is fixed with the sucker of adsorbable human body skin.
