Description
Technical field
The present invention relates to transfusion bottle stopper puncture outfit, specifically a kind of transfusion bottle stopper with anti-drop function is punctured
Device.
Background technique
Venous transfusion is a common technology means of current medical industry, in infusion process, only require infusion bottle or
The arm of person's infusion bag and patient are kept certain height difference, with no restrictions to the posture of patient, patient are even allowed for be infused
Infusion bottle is lifted in journey slightly to walk about, and the entire infusion process duration is longer, patient or other people touch unintentionally can
The bottle plug puncture unit being inserted in infusion bottle can be caused to fall off, cause blood back, pollute bottle plug puncture unit, need medical staff's replacement defeated
Liquid leather strap is infused again or even the patient of some awareness of safety weakness or families of patients, can will fall off bottle stopper on the ground rapidly
Puncture outfit, which reinserts, to be continued to be infused in bottle, by pollutant afferent veins entrained by contaminated bottle plug puncture unit, consequence without
The method imagination, therefore, it is particularly necessary to design a kind of bottle plug puncture unit that can prevent from falling off in infusion process.
Summary of the invention
The technical problem to be solved by the present invention is to propose a kind of there is anti-dropout the shortcomings that for the above prior art
The transfusion bottle stopper puncture outfit of function, including shape are in sagittate puncture needle, and puncture needle includes for being pierced into inside infusion bottle

Hand-held manage offers circlip groove along hand-held pipe circumferencial direction close to one end of connecting tube, is fixed with retaining ring in circlip groove, is puncturing
Infusion hole is provided in the axial direction in the middle part of needle, infusion hole is connected with the infusion port that needle point side is arranged in, covers in connecting tube
Equipped with connector sleeve, it is embedded with rubber sleeve between connector sleeve and connecting tube, connector sleeve and rubber sleeve are column, and the end of connector sleeve
Face is oval and identical as the shape of needle point bottom, size, is equipped with step baffle, step far from one end of needle point in connector sleeve
The other end of baffle is bonded with retaining ring；
The hand-held threaded one end for managing separate connecting tube is connected with coupling tube, and the coupling tube other end connects perfusion tube, in coupling tube
Side offers threaded hole, and cooperation is equipped with the air inlet pipe for balancing infusion bottle inside and outside pressure in threaded hole；
The bottle plug puncture unit of conventional monolithic is divided into puncture needle and connector sleeve two parts in the technical program, and tradition is cut
The rounded bottle plug puncture unit in face is changed to ellipse, which guarantees that bottle plug puncture unit can smoothly be inserted into bottle stopper, is arranged bottle stopper
On connector sleeve, by the way that hand-held pipe rotates by a certain angle, syringe needle and connector sleeve is staggered certain angle, guaranteed in infusion process
Middle bottle plug puncture unit will not fall off, and in this configuration, setting step baffle prevents bottle plug puncture unit insertion too deep, entirely slide into bottle
In, setting retaining ring guarantees that connector sleeve is bonded always with the lower end of needle point, and setting rubber sleeve plays sealing function, prevents liquid from passing through
Gap outflow between connector sleeve and puncture needle, setting air inlet pipe is for balancing infusion bottle inside and outside pressure.
The technical solution that the present invention further limits is:
Prior hand held pipe be located at circlip groove far from connecting tube a lateral edge hold pipe axially offer card slot, on retaining ring be equipped with
The chuck of card slot cooperation can limit retaining ring by the cooperation of card slot and chuck and be rotated along pipe circumferencial direction is held；
The aforementioned one end of step baffle far from needle point is along the circumferential direction successively arranged the first positive stop lug boss and the second positive stop lug boss, gear
The periphery of circle is extended with pointer outward, and pointer is arranged between the first positive stop lug boss and the second positive stop lug boss, works as fixation
Connector sleeve, while when rotating puncture needle, pointer can rotate between the first positive stop lug boss and the second positive stop lug boss, when pointer is gone to
When being bonded with the first positive stop lug boss, connector sleeve is completely coincident close to one end of needle point with needle point bottom, to facilitate medical worker
Puncture needle is inserted or pull out, when pointer, which is gone to, to be bonded with the second positive stop lug boss, connector sleeve and needle point are staggered 90 °, are avoided that defeated
Puncture needle falls off during liquid；
The beneficial effects of the present invention are: the bottle plug puncture unit of conventional monolithic is divided into puncture needle and connector sleeve two parts, and
The rounded bottle plug puncture unit of conventional cross-section is changed to ellipse, which guarantees that bottle plug puncture unit can smoothly be inserted into bottle stopper, makes
Bottle stopper is set on connector sleeve, by rotating hand pipe, syringe needle and connector sleeve is staggered certain angle, guaranteed in infusion process
Bottle plug puncture unit will not fall off, and in this configuration, setting step baffle prevents bottle plug puncture unit insertion too deep, lead to entire bottle stopper
Puncture outfit slides into bottle, and setting retaining ring guarantees that connector sleeve is bonded always with the lower end of needle point, and setting rubber sleeve plays sealing function,
Prevent liquid by the gap outflow between connector sleeve and puncture needle, setting air inlet pipe is for balancing infusion bottle inside and outside pressure；
Retaining ring can be limited by the cooperation of card slot and chuck to be rotated along pipe circumferencial direction is held, by the first positive stop lug boss and
The rotation angle of second positive stop lug boss limit pointer provides two stations to the device, medical worker is facilitated to operate, when pointer turns
To when being bonded with the first positive stop lug boss, connector sleeve is completely coincident close to one end of needle point with needle point bottom, to facilitate medical matters people
Member inserts or pull out puncture needle, and when pointer, which is gone to, to be bonded with the second positive stop lug boss, connector sleeve and needle point are staggered 90 °, is avoided that
Puncture needle falls off in infusion process.
