Abstract
The utility model discloses a thorax puncture drainage syringe, which is composed of a thorax puncture needle 1, a rubber pipe 2, an injection needle tube 3, and a push-and-pull pin 4, wherein, a suction one-way valve 6 is arranged in an injection port of the injection needle tube 3; a delivery tube 5 is arranged on the front part of the injection needle tube 3 and is provided with an extrusion one-way valve 6' inside. The thorax puncture drainage syringe can be operated continuously by oneperson, does not pollute environment, does not generate retrograde infection and pneumothorax complication easily, and has the advantages of time saving, labor saving, simple structure, and easy operation. The utility model can be widely used in thorax puncture surgical operations of patients.
Description
This utility model relates to the improvement of syringe, belongs to medical apparatus, and specifically a kind of breast connects the stream syringe, is applicable to patient's breast is worn art.
The art drawing liquid is worn to patient's breast by hospital at present, the used medical apparatus of bleeding is generally ordinary syringe, by thoracic-puncture needle, rubber tube, the syringe cylinder of 50-100mL, push-and-pull bolt and vascular forceps constitute, adopt this syringe drawing liquid or bleed, need repeatedly take out, because general hydrothorax (or gas) amount is at 1000-2000mL, whenever take out about 50mL, need to clamp rubber tube with vascular forceps, again syringe nipple is extracted from the thoracic-puncture needle rubber tube, behind the Extract (or gas) in the exhaustjet syringe, inserted again and carry out drawing liquid (or gas), like this, just can finish a breast after approximately carrying out 20-40 time repeatedly and wear art, and need two people carry out during operation, time-consuming, effort, simultaneously, also occur the puncture needle displacement easily, cause retrograde infection, cause patient pneumothorax complication etc. to occur.
This reality have novel purpose be to provide a kind of making simple in structure, easy, thoracic-puncture needle once insert can be repeatedly drawing liquid (or gas) continuously, and can one man operation, time saving and energy saving breast connects the stream syringe.
This utility model is achieved in that this breast connects the stream syringe and is made of thoracic-puncture needle, rubber tube, syringe cylinder, push-and-pull bolt, establish the suction check valve in the injection port of its syringe cylinder, establish delivery line on the anterior simple wall of syringe cylinder, establish in the delivery line and extrude check valve.This breast connects the stream syringe and also implements by following measure: the suction check valve is made of valve pocket, spheroid, spring, and spheroid gets lodged in being drawn on the mouth of valve pocket, and spring is pressed on the valve pocket spring base, and valve pocket can directly be made of syringe cylinder syringe needle mount pad wall; Extruding check valve also is made of valve pocket, spheroid, spring, spheroid gets lodged on the export mouth of valve pocket, spring is pressed on the valve pocket spring base, and valve pocket can directly be made of the delivery line tube wall, when the push-and-pull bolt is pulled outwardly, the compression of suction one-way valve spring, spheroid is past to move down, and the state that the suction check valve is in out is opposite, extrude the state that check valve is in the pass, liquid (or gas) just can be drawn in the syringe cylinder; When the push-and-pull bolt inwardly pushed away, spheroid moved outward, extruded the one-way valve spring compression, extruded the state that check valve is in out, and on the contrary, the suction check valve is in the state of pass, and liquid (or gas) just can be extruded in syringe cylinder, but this process repeatable operation; On delivery line, also can connect the derivation sebific duct, derive sebific duct and be communicated with storage liquid (or gas) bottle again, to prevent the extract contaminated environment.
Advantage of the present utility model is can people's continued operation, save time, laborsaving, free from environmental pollution, be difficult for producing retrograde infection pneumothorax complication, simultaneously, simple in structure, easy operation.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model suction one-way valve structures sketch map.
Fig. 3 extrudes the one-way valve structures sketch map for this utility model.
Make this utility model with reference to Fig. 1,2,3.This breast connect stream syringe constitute by thoracic-puncture needle 1, rubber tube 2, injection needle 3, push-and-pull bolt 4, establish suction check valve 6 in the injection port of its syringe cylinder 3, establish delivery line 5 on the syringe cylinder 3 anterior barrels, establish in the delivery line 5 extrude check valve 6 '.Suction check valve 6 is made of valve pocket 7, spheroid 8, spring 9, spheroid 8 gets lodged in being drawn on the mouth of valve pocket 7, spring 9 is pressed on the valve pocket spring base 10, extrude check valve 6 ' by valve pocket 7, spheroid 8 ', spring 9 ' constitute, spheroid 8 ' get lodged in valve pocket 7 ' export mouth on, spring 9 ' be pressed in valve pocket spring base 10 ' on, connecing on the delivery line 5 derives sebific duct 11, derives sebific duct 11 and storage liquid (or gas) bottles 12 and is communicated with.
