Abstract
The utility model discloses a fingerstall type exhaust needle, belonging to medical apparatus and instruments; including the puncture syringe needle, its main technical essential is: the needle handle neck of the puncture needle head is provided with a rubber finger sleeve, the top end of the finger sleeve is provided with a linear air vent, the needle handle neck is provided with a filter, and the needle handle neck is sealed with the rubber finger sleeve. The fingerstall type exhaust needle can be used for the first aid of tension pneumothorax, and is flexible and convenient to use.
Description
Affiliated technical field
This utility model relates to field of medical products, says it is a kind of finger cot type exhaust needle that is used for the first aid of tension force pneumothorax in detail.
Background technology
As everyone knows: tension pneumothorax claims tension pneumothorax again, be because the breach that pleural space communicates is the effect of individual event flap valve, flap valve is open when air-breathing, 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, is fit to inpatient, and its deficiency is: the drainage bag pipeline is long, and other operation that folding phenomenon and influence are rescued easily takes place.
Owing to adopt the closed drainage of pleural cavity aerofluxus to exist the drainage bag pipeline long, the deficiency of other operation of folding phenomenon and influence rescue easily takes place, 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.
Summary of the invention
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 of other operation of folding phenomenon and influence rescue easily takes place, and provide a kind of finger cot type exhaust needle, 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.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of finger cot type exhaust 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.Needle handle cervical region and the sealing of rubber fingerstall.
The beneficial effects of the utility model are, owing to be provided with the rubber fingerstall of band wire 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 prevent 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
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1, structural representation of the present utility model.
1. rubber fingerstall among the figure, 2. blow vent, 3. filter, 4. piercing needle, 5. needle handle.
The specific embodiment
Below in conjunction with the drawings and specific embodiments finger cot type exhaust needle of the present invention is described further, to help understanding content of the present invention.
As shown in Figure 1, it is a kind of finger cot type exhaust needle that goes for the tension pneumothorax first aid, needle handle 5 cervical regions of piercing needle 4 are provided with rubber fingerstall 1, 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 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)
