Description
Technical field
This utility model technical field of medical instruments particularly relates to a kind of safety thoracentesis needle.
Background technology
Hydrothorax is comparatively common in clinical, can be caused by pleura inflammation, tumor, connective tissue disease etc.The method treatment of hydrothorax being adopted thoracentesis is gone up in present medical treatment, and traditional thoracentesis is to be made of piercing needle connection glass connector latex tubing and drawing liquid syringe.When clinical use, normally to finish by two people's compounding practices, said method not only takies the human resources, and time-consuming, effort.Medical personnel determine depth of needle by range estimation when inserting needle, are difficult to hold the degree of depth that syringe needle enters torso model; Because the draw point that puncture is used is long, be easy to changing position in addition, or stab internal organs easily when patient's cough and heartbeat, cause iatrogenic injury, bring unnecessary misery to the patient.
Summary of the invention
This utility model provides the safety thoracentesis needle that can fixedly secure behind a kind of simple in structure, easy operating and the inserting needle for solving the technical problem that exists in the known technology.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is: the safety thoracentesis needle, comprise piercing needle, the needle handle that is connected with piercing needle and the needle tubing that is connected with needle handle, it is characterized in that: described piercing needle is provided with the syringe needle localizer near its front portion, the piercing needle head passes the centre bore of syringe needle localizer front end face, the syringe needle localizer comprises the sleeve that is connected with the needle handle leading section, sleeve one end is shaped on boss, the sleeve boss side surfaces is fixed with catch, and catch one side is connected with adhesive discs.
This utility model can also adopt following technical scheme: described sleeve is connected with needle handle by screw thread.
Described adhesive discs front surface is provided with the adhesive-layer that is used to be adhesively fixed.
Advantage and the good effect that the utlity model has are: because this utility model adopts technique scheme, when the patient is implemented paracentesis, rotation syringe needle localizer, the length that makes piercing needle extended needle localizer front end face is the length that is fit to enter piercing needle in the human body, after the puncture, adhesive discs is bonded on the human body skin, puncture needle can be fixed on patient's thoracic wall like this, extract liquid by needle tubing again.Need not the assistant when medical personnel operate like this helps to fix, not only its paracentesis depth is accurately easy to control, and fixation, can avoid causing puncture needle to stab its internal organs owing to patient body position's conversion or when patient's cough and heartbeat, can effectively prevent the generation of iatrogenic injury.This puncture needle is easy and simple to handle, is easy to grasp.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, piercing needle; 2, needle handle; 3, syringe needle localizer; 3-1, sleeve; 3-2, boss; 4, adhesive discs; 4-1, adhesive-layer; 5, catch; 6, needle tubing.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, now exemplify following examples, and conjunction with figs. is described in detail as follows: see also Fig. 1, safety thoracentesis needle, the needle handle 2 that comprise piercing needle 1, is connected with piercing needle and the needle tubing 6 that is connected with needle handle.Described piercing needle 1 is provided with syringe needle localizer 3 near its front portion, and the syringe needle head passes the centre bore of syringe needle localizer 3 front end faces.Syringe needle localizer 3 comprises the sleeve 3-1 that is connected with needle handle 2 leading sections, and described sleeve one end is shaped on female thread, and is connected with needle handle by screw thread.The sleeve other end is shaped on and its all-in-one-piece boss 3-2, and telescopic boss one side is fixed with catch 5, and catch one side is connected with adhesive discs 4.Described adhesive discs 4 front surfaces are provided with the adhesive-layer 4-1 that is used to be adhesively fixed.
Operation principle of the present utility model is: during use, rotation syringe needle localizer 3, the length that makes piercing needle 1 extended needle localizer front end face is the length that is fit to enter piercing needle in the human body, after the puncture, adhesive discs is bonded on the human body skin, puncture needle can be fixed on patient's thoracic wall like this, extract liquid by needle tubing again.
