Abstract
The utility model belongs to the field of medical apparatuses and particularly discloses a puncture needle for sucking pus of a liver. The puncture needle comprises a needle head, a needle tube, a piston and a piston rod and is characterized in that the side wall of the needle head is uniformly provided with multiple sucking holes, the needle tube is connected with a releasing tube and an air valve. The puncture needle for sucking the pus of the liver has a simple structure and reasonable design, can be applied flexibly, has high pus sucking efficiency and large pus sucking area, is beneficial to the recovery of patients and is suitable for wide popularization.
Description
(1) technical field
This utility model belongs to medical instruments field, and particularly a kind of liver is taken out the pus puncture needle.
(2) background technology
In the diagnoses and treatment process to liver abscess, it is the instrument that the medical worker uses always that liver is taken out the pus puncture needle, but when operation because of pus than thickness, be easy to cause puncture needle to stop up, puncture needle stops up the back, and half adopts normal saline to wash repeatedly, has influenced puncture speed, in addition, existing piercing needle is the single tube syringe needle, it is less to take out the pus area, and it is not thorough to take out pus, causes the interior pus of vomica residual, treat not thoroughly, rehabilitation course is slow.
(3) summary of the invention
This utility model provides a kind of liver simple in structure, easy to use to take out the pus puncture needle in order to remedy the deficiencies in the prior art.
This utility model is achieved by the following technical solution:
A kind of liver is taken out the pus puncture needle, comprises syringe needle, needle tubing, piston and piston rod, it is characterized in that: be evenly distributed with several suckings on the described syringe needle sidewall, be connected with releasing tube and breather valve on the needle tubing.
This utility model is provided with a plurality of suckings on medicated pillow, help to improve the absorption efficiency of puncture needle to pus in the body, because the finite volume of needle tubing, for preventing the repeatedly extraction and the insertion of syringe needle in operating process, on needle tubing, be provided for collecting the releasing tube of extracting pus out, and the opening by breather valve, realize that position of piston replys.
More excellent scheme of the present utility model is:
Be the flexible Application releasing tube, described releasing tube is provided with control valve, according to what of pus in the body, determines the switch of control valve, thereby the use of selecting releasing tube whether.
This utility model is simple in structure, and is easy to use, reasonable in design, and applying flexible is taken out pus efficient height, area is big, is beneficial to patients ' recovery, is suitable for wide popularization and application.
(4) description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 syringe needle, 2 needle tubings, 3 pistons, 4 piston rods, 5 suckings, 6 releasing tubes, 7 breather valve, 8 control valves.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises syringe needle 1, needle tubing 2, piston 3 and piston rod 4, is evenly distributed with several suckings 5 on described syringe needle 1 sidewall, is connected with releasing tube 6 and breather valve 7 on the needle tubing 2; Described releasing tube 6 is provided with control valve 8.
After determining the position of pus in the sufferer liver, the pus position is anaesthetized, use 1 pair of human body of syringe needle to puncture, after syringe needle 1 reached the precalculated position, application piston bar 4 was pulled outwardly piston 3 along needle tubing 2, a plurality of suckings 5 on the syringe needle 1 are extracted the pus in the liver out under pressure, and outwards discharge by releasing tube 6, when piston 3 moves to needle tubing 2 terminal, breather valve 7 is opened, make piston 3 be returned to the origin-location, carry out drawing liquid once more; When the intravital pus of people more after a little while, the control valve on the releasing tube 68 is closed, directly store puss and get final product with needle tubing 2.
Claims (2)
1. a liver is taken out the pus puncture needle, comprise syringe needle (1), needle tubing (2), piston (3) and piston rod (4), it is characterized in that: be evenly distributed with several suckings (5) on described syringe needle (1) sidewall, be connected with releasing tube (6) and breather valve (7) on the needle tubing (2).
2. liver according to claim 1 is taken out the pus puncture needle, it is characterized in that: described releasing tube (6) is provided with control valve (8).
