Abstract
The utility model discloses an air exhaust needle for puncturing pneumothorax. The tail part of an air exhaust needle is provided with a valve type one-way exhaust valve 2. The air exhaust needle for puncturing pneumothorax with the structure is used conveniently. The utility model has the advantages of reliable effect, less patients' damage and convenient movement.
Description
This utility model relates to a kind of puncture exhaust needle for the treatment of pneumothorax clinically.
Clinically for the treatment of pneumothorax, particularly tension pneumothorax, often need urgent aerofluxus, urgent exhaust needle structure commonly used at present is: prick a fingerstall at the afterbody of entry needle, the fingerstall end is cut a crack, fingerstall has played unidirectional flap valve effect, unreliable because of unidirectional flap valve effect in the use of this kind exhaust needle, effect is not good enough; The thoracentesis suction often needs repeatable operation, increases patient's misery; Certain position need be performed an operation and keep to closed drainage of pleural cavity, is not easy to patient activity.
The purpose of this utility model be to provide a kind of overcome above-mentioned shortcoming, easy to use, reliable for effect, patient trauma is little, activity pneumothorax puncture exhaust needle easily.
This utility model is achieved in that a kind of pneumothorax puncture exhaust needle, and this exhaust needle afterbody is provided with the flapper-type one-way exhaust valve.
The utility model has the advantages that: 1, easy to use, reliable for effect.It is more reliably than the fingerstall one-way gas exhaust of tradition use to use one-way exhaust valve, uses also easily, is specially adapted to field first aid.
2, patient trauma is little, activity is convenient.Use this utility model exhaust needle, reliable because of unidirectional exhaust effect, do not need repeatable operation, patient's damage is little, and is painful few, and when doing the aerofluxus treatment, patient can do some simple actions, movable convenient.
Below in conjunction with accompanying drawing this utility model is described in further detail:
Fig. 1 is a cross-sectional schematic of the present utility model.
Fig. 2 is the vertical view of Fig. 1 valve 3 parts.
As shown in Figure 1, this utility model comprises syringe needle 1 and one-way exhaust valve 2 two parts, syringe needle 1 can adopt the normal injection syringe needle 16～No. 18, one-way exhaust valve 2 is connected on the afterbody of syringe needle 1, and one-way exhaust valve 2 inside are provided with valve 3, and valve 3 adopts elastomeric material, can adopt the altex glove material during actual the use, for easy to exhaust and valve 3 opens and closes flexibly, valve 3 circumferencial directions are provided with a plurality of semicircle breach 4, as shown in Figure 2.
This utility model use principle is as follows: when being malleation in the thoracic cavity, gas backs down valve 3 and excretes, and when the thoracic cavity was negative pressure, valve 3 sealed air vent under extraneous gas pressure, and gas can not enter the thoracic cavity.
Claims (2)
1, a kind of pneumothorax puncture exhaust needle, it is characterized in that: this exhaust needle afterbody is provided with flapper-type one-way exhaust valve (2).
2, pneumothorax puncture exhaust needle according to claim 1, it is characterized in that: this one-way exhaust valve inside is provided with valve (3), and valve (3) circumferencial direction is provided with a plurality of semicircle breach (4).
