Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of perforator, the structure improved perforator that uses on particularly a kind of transfusion device.
Background technology
In the medical procedure of each medical institutions, transfusion is one of therapeutic modality of using always.In transfusion device, former structure is to establish a transfusion needle between infusion bottle and tube for transfusion, inserts in the infusion bottle by transfusion needle and carries medicinal liquid.Simultaneously, also an air inlet needle to be in infusion bottle, inserted,, negative pressure can be do not produced to keep the air pressure balance inside and outside the infusion bottle.Now, people adopt perforator to substitute transfusion needle and air inlet needle simultaneously, and perforator is a key element that connects tube for transfusion and infusion bottle.
Chinese patent application [publication number: the CN2531793] utility model patent " perforator " that the inventor proposes has well solved the problem of the air pressure balance inside and outside the infusion bottle.This perforator comprises needle tubing, syringe needle, drain pipe and body, is cavity in the needle tubing, and there is a liquid-through hole its front portion, and syringe needle is positioned at needle tubing, and wherein needle tubing is to be fixed on the body and with body by glue to form sealing.But assemble in the process of perforator at the automatic assembling of reality, the inventor finds that also this product exists certain weak point, on the one hand be automatic assembling when the needle tubing of assembling perforator and this bulk phase are connected, because body is solid with taking over the position that is connected, dropping in glue on the needle tubing during assembling is squeezed and is easy to flow out, unhygienic when the dust in air that adheres to glue causes perforator to use, and can stick at the surface of needle tubing behind the glue partially hardened.On the other hand, owing to do not have the edge of protrusion on the body, cumbersome when automatic assembling assembling perforator.
Summary of the invention
The objective of the invention is provides a kind of rational in infrastructure at the existing the problems referred to above of existing perforator, is fit to the structure improved perforator of automatic assembling ease of assembly.
Purpose of the present invention can realize by following technical proposal: a kind of structure improved perforator, it comprises needle tubing, syringe needle and body, described needle tubing inside is cavity, the needle tubing front portion has liquid-through hole, described syringe needle is positioned at needle tubing and its head stretches out needle tubing, passage is arranged in the syringe needle, syringe needle and needle tubing all are fixed on the body, body is provided with drain pipe, this drain pipe communicates with the inner chamber of needle tubing, it is characterized in that described body is provided with the needle tubing seat, the inboard of this needle tubing seat has annular groove.
This perforator is the device on being used to infuse, in this perforator, medicinal liquid in the infusion bottle is to enter syringe intracavity by the liquid-through hole on the needle tubing, again by drain pipe to tube for transfusion, air enters in the infusion bottle by the passage in the syringe needle, to keep the infusion bottle inside and outside air pressure balance, syringe needle and needle tubing all are fixed on the needle tubing seat on the body, because the inboard of needle tubing seat has annular groove, like this when needle tubing and needle tubing seat body on of automatic assembling, be coated in glue on the needle tubing and be squeezed and just flow in the annular groove of needle tubing seat inboard automatically at the assembling perforator.
In above-mentioned structure improved perforator, between needle tubing and needle tubing seat, be provided with and both are connected mutually and make needle tubing and the needle tubing seat forms the interface arrangment one of sealing.
In above-mentioned structure improved perforator, described interface arrangment one comprises draw-in groove one that is arranged in the needle tubing and the convex tendon one that is arranged on the needle tubing seat.When convex tendon one was stuck in the draw-in groove one, needle tubing just was fixed on the needle tubing seat.
As another kind of situation, in above-mentioned structure improved perforator, described interface arrangment one comprises convex tendon two that is arranged in the needle tubing and the draw-in groove two that is arranged on the needle tubing seat.When should convex tendon two being stuck in the draw-in groove two, needle tubing just be fixed on the needle tubing seat, when automatic assembling assembles, needle tubing and needle tubing seat directly are connected mutually by the draw-in groove that matches and convex tendon and form sealing.Certainly in order to guarantee that whole perforator does not come off, on this perforator, add glue again, make this perforator more firm, like this safety and reliability in the process of transfusion.
In above-mentioned structure improved perforator, described body is provided with the convex edge of protruding this body end face.
So not only make things convenient for automatic assembling assembling perforator, and in using the perforator process, finger can directly withstand on the place, convex edge and make easily energetically, operates more convenient.
In above-mentioned structure improved perforator, described body sidepiece offers blow vent, and described blow vent communicates with the passage of syringe needle.Be in order to keep the inside and outside air pressure balance of infusion bottle like this.
In above-mentioned structure improved perforator, be provided with air filtration film plug in the described blow vent, between the blow vent place of air filtration film plug and body, be provided with and both are connected mutually and make the blow vent place of air filtration film plug and body form the interface arrangment two of sealing.Extraneous air by the interior passage of the blow vent in the air filtration film plug and syringe needle after, enter in the infusion bottle from the outlet of syringe needle.Prevent that like this objectionable impurities such as airborne microgranule from entering in the infusion bottle.
In above-mentioned structure improved perforator, described interface arrangment two comprise be arranged on the air filtration film beyond the Great Wall convex tendon three and be arranged on the draw-in groove three at the blow vent place of body.When convex tendon three was stuck in draw-in groove three, air filtration film plug also just was fixed on the blow vent place of body.
As another kind of situation, in above-mentioned structure improved perforator, described interface arrangment two comprise be arranged on the air filtration film beyond the Great Wall draw-in groove four and be arranged on the convex tendon four at the blow vent place of body.In like manner, when convex tendon four is stuck in draw-in groove four, air filtration film plug also just is fixed on the blow vent place of body, does not need glue directly to be fixed in body blow vent place to air filtration film fork clip like this, make this perforator use or moving process in phenomenons such as air filter membrane plug can not come off.
Compared with prior art, this structure improved perforator is because the stub (tube) of body has draw-in groove, therefore when the needle tubing seat of automatic assembling at the needle tubing of assembling perforator and body, being coated in glue on the needle tubing during assembling is squeezed and just flows in the annular groove of needle tubing seat inboard automatically, the convex edge that has protrusion on the body, also more convenient in automatic assembling assembling puncture.Whole in addition perforator directly can be connected the adapter of perforator and body without glue by the interface arrangment of convex tendon and draw-in groove is set.Whole perforator device is ventilated by gap between syringe needle and the needle tubing and blow vent and is kept the balance of infusion bottle inner and outer air pressure, and therefore operation is very laborsaving, has improved work efficiency.
