Abstract
The utility model discloses a pleura puncture needle, belonging to medical equipment. The pleura puncture needle comprises a puncture needle head. The pleura puncture needle is mainly technically characterized in that a rubber finger guard is arranged on the neck of a needle handle of the puncture needle head, a linear ventilation hole is arranged on the top end of the finger guard, a filter is arranged on the neck of the needle handle, and the neck of the needle handle is sealed with the rubber finger guard. The pleura puncture needle is suitable for emergency exhaust of tension pneumothorax.
Description
Technical field
This utility model relates to medical instruments field, says it is a kind of deflated pleura puncture needle of tension force pneumothorax first aid that is used in detail.
Background technology
As everyone knows: tension pneumothorax is claimed tension pneumothorax again, is that flap valve is open when air-breathing because the breach that pleural space communicates is the effect of individual event flap valve; The air admission pleural space; Flap valve is closed during expiration, and air can not be discharged pleural space, and intrathoracic pressure sharply rises; The Therapeutic Principle is aerofluxus immediately, reduces intrathoracic pressure.
At present, clinically closed drainage of pleural cavities that adopt more, be characterized in: drainage bag replaces exhaust needle, suitable inpatient, its deficiency is: the drainage bag pipeline is long, is prone to take place other operation of folding phenomenon and influence rescue.
Owing to adopt the closed drainage of pleural cavity aerofluxus to exist the drainage bag pipeline long; The deficiency that is prone to that folding phenomenon takes place and influences other operation of rescuing; Have significant limitation in the use, can not satisfy tension force pneumothorax first aid aerofluxus rapidly, requirement smooth, that do not interfere with other measure.
The utility model content
The purpose of this utility model just is to overcome existing tension force pneumothorax first aid and adopts the closed drainage of pleural cavity aerofluxus to exist the drainage bag pipeline long; The deficiency that is prone to that folding phenomenon takes place and influences other operation of rescuing; And a kind of pleura puncture needle is provided; Can reduce pressure immediately after thrusting pleural space, satisfy tension force pneumothorax first aid aerofluxus rapidly, requirement smooth, that do not interfere with other measure.
This utility model adopts following technical solution: a kind of pleura puncture needle, comprise piercing needle, and it is characterized in that: the needle handle cervical region of piercing needle is provided with the rubber fingerstall, and the fingerstall top is provided with a linear blow vent.The needle handle cervical region is provided with filter.
Described needle handle cervical region and the sealing of rubber fingerstall.
This pleura puncture needle of this utility model; Owing to be provided with the rubber fingerstall of band wire property blow vent at the needle handle cervical region of piercing needle; Exhaust resistance is little; Puncture needle thrusts behind the pleural space exhaust decompression immediately, and prevents the air admission pleural space, satisfy tension force pneumothorax first aid aerofluxus rapidly, requirement smooth, that do not interfere with other measure.
Description of drawings
Fig. 1 is the structural representation of the pleura puncture needle of this utility model.
1. rubber fingerstall among the figure, 2. blow vent, 3. filter, 4. piercing needle, 5. needle handle.
The specific embodiment
Be described further below in conjunction with accompanying drawing and specific embodiment pleura puncture needle, to help the content of understanding this utility model this utility model.
As shown in Figure 1, be a kind of pleura puncture needle that goes for the tension pneumothorax first aid, needle handle 5 cervical regions of piercing needle 4 are provided with rubber fingerstall 1, and rubber fingerstall 1 top is provided with a linear blow vent 2.Be tightly connected between needle handle 5 cervical regions of piercing needle 4 and the rubber fingerstall 1.Rubber fingerstall 1 is a thin-walled rubber.
During use, thrust pleural space hindering side second rib mterclavicle midline, be fixed with fixation clamps, because rubber fingerstall 1 is straight-through through linear blow vent 2 and environment, can reduce pressure immediately, filter 3 can prevent the air admission pleural space.
Owing to be provided with the rubber fingerstall of band wire property blow vent at the needle handle cervical region of piercing needle; Exhaust resistance is little; Puncture needle can reduce pressure after thrusting pleural space immediately, and filter can prevent the air admission pleural space, satisfy tension force pneumothorax first aid aerofluxus rapidly, requirement smooth, that do not interfere with other measure.
Claims (3)
1. a pleura puncture needle comprises piercing needle, it is characterized in that: the needle handle cervical region of piercing needle is provided with the rubber fingerstall, and the fingerstall top is provided with a linear blow vent, needle handle cervical region and the sealing of rubber fingerstall.
2. pleura puncture needle as claimed in claim 1 is characterized in that: described needle handle cervical region and the sealing of rubber fingerstall.
3. according to claim 1 or claim 2 pleura puncture needle, it is characterized in that: described needle handle cervical region is provided with filter.
