Abstract
The utility model discloses a bottle stopper puncture outfit, which comprises a steel needle, an air needle, a fixing sleeve and a needle seat; an air port and a liquid outlet pipe are arranged in the needle seat; the air needle is internally arranged in the steel needle and a certain space is left; the interior of the steel needle is hollow, the head part is a closed cone shape, the side wall of the steel needle is provided with a gap, and the outlet at the lower end is communicated with the liquid outlet pipe; the air needle is a hollow pipe body, the outlet at the upper end of the air needle is a flat head, the end surface is arranged at the same plane with the upper end of the gap of the steel needle or is slightly higher than the upper end of the gap, and the outlet at the lower end is communicated with the air port. The puncture outfit can not only reduce the number of puncture, but can also not contact with the rubber stopper of the transfusion bottle during the puncture process, so as to avoid the occurrence of the clogging phenomena of the air port and the liquid outlet pipe, further to ensure the safe use of the patients. The utility model is characterized by simple structure, light and convenient operation, strong puncture, safety and health.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to the bottle plug puncture unit on a kind of disposable infusion syringe.
Background technology
For avoiding cross infection, extensively adopt disposable transfusion device in the society.The bottle plug puncture unit of traditional infusion device is made up of tube for transfusion, transfusion needle and air inlet needle; During transfusion, transfusion needle and air inlet needle are inserted infusion bottle, and medicinal liquid is carried toward tube for transfusion by transfusion needle, and air is entered by air inlet needle, are used for keeping the inside and outside air pressure balance of infusion bottle, the continuous conveying that keeps medicinal liquid.In the whole operation process, need slotting bottle twice, not only use inconvenience, and damage bottle stopper easily; Simultaneously when puncture, because of sharp keen transfusion needle pin mouth and air inlet needle pin mouth directly contact the plug of infusion bottle, be easy to produce scrap gum, this may stop up transfusion needle and air inlet needle on the one hand, and the buffings of Chan Shenging is sneaked into medicinal liquid on the other hand, brings harm to the patient.
The utility model content
The purpose of this utility model is to provide a kind of bottle plug puncture unit, only needs once to insert bottle, and prevents that scrap gum from sneaking in the medicinal liquid, solves transfusion needle and air inlet needle by the scrap gum blockage problem, has safety, health, convenience operation.
To achieve these goals, this utility model adopts following technical scheme:
A kind of bottle plug puncture unit is made up of draw point, air needle, fixed cover and needle stand; Be provided with blow vent and drain pipe in the needle stand; Air needle is built in the draw point, and leaves certain clearance; Draw point inner hollow, head are the closed circular taper, and its sidewall has a breach, and the lower end outlet communicates with drain pipe; Air needle is a hollow tube, and its upper end outlet is tack, and end face and draw point breach upper end are on same plane or a little more than this breach upper end, the lower end outlet communicates with blow vent.
The blow vent of above-mentioned needle stand sidewall is provided with air filter and filter membrane.
During use, the draw point head inserts infusion bottle, and extraneous air enters the needle stand blow vent by air filter and filter membrane, enters infusion bottle through air needle by draw point breach top; Medicinal liquid is entered by the breach of draw point sidewall, with after the gap between draw point and the air needle arrives in the tube for transfusion of needle stand, is exported by the liquid outlet of needle stand bottom again.Adopt the perforator of above technical scheme, the draw point head is a sharp keen circular cone, and it is laborsaving, convenient to puncture; The vent needle that adopts is positioned at the draw point cavity; not only reduce puncture time; and in piercing process, do not contact with the rubber stopper of infusion bottle; prevent that damaged, generation buffings from appearring in rubber stopper; thereby avoided the obstruction of blow vent and drain pipe; the phenomenon that buffings enters medicinal liquid takes place, and guarantees that patient safety uses.In addition, air filter and filter membrane play the filtration of impurity, prevent that harmful substances such as airborne microgranule from entering in the infusion bottle.The utlity model has simple in structure, operation is light, puncture force is strong, the characteristics of safety and sanitation.

Fig. 3 is a perspective view of the present utility model.
The specific embodiment
As shown in Figure 1, 2, 3, this utility model provides a kind of bottle plug puncture unit, is made up of needle stand 1, draw point 2, air needle 3, air filtration film 4, fixed cover 5, air filter guard shield 6 and bottle stopper overcoat 7; Bottle stopper overcoat 7 is socketed in the outside of draw point 2; Air filter guard shield 6 is socketed in blow vent 11 outsides of needle stand 1 sidepiece; Needle stand 1 is connected as a single entity with blow vent 11, drain pipe 12, and air needle 3 is fixed on the needle stand 1, and is built in the breather 13, is provided with fixed cover 5 between draw point 2 and the needle stand 1, and fixed cover 5 is fixed on draw point 2 on the needle stand 1.
Above-mentioned blow vent 11 is positioned at the sidepiece of needle stand 1, is provided with one deck air filtration film 4 in the blow vent 11.
Above-mentioned air needle 3 is built in the draw point 2, and leaves certain clearance and pass through for medicinal liquid; In the air needle 3 is passage 31, and air needle 3 outlets 32 are tack, and draw point 2 heads are the closed circular taper, and are so the puncture of this perforator is very capable, laborsaving during operation.
Above-mentioned draw point 2 its sidewalls have a breach 21, and after this perforator inserted infusion bottle, cavity between breach 21, draw point 2 and the air needle 3 and drain pipe 11 formed medicine liquid channel, enter tube for transfusion for the medicinal liquid in the infusion bottle.Simultaneously, blow vent 11, passage 31 and air needle 3 outlets 32 form air duct, make in the air admission infusion bottle, keep the inside and outside air pressure balance of infusion bottle, reach the effect of safe infusion.
