Abstract
The puncture outfit provided by the utility model belongs to medical device technical field, which solves the problem that the existing puncture outfit is hard to be inserted into the infusion bottle. The puncture outfit comprises a needle tube, a needle, a liquid outlet pipe and an air vent port. A cavity is arranged in the needle tube. The needle which is arranged in the needle tube penetrates the needle tube and the head of the needle extends out of the needle tube. An air vent hole is arranged in the needle. The intracavity of the liquid outlet pipe is communicated with the intracavity of the needle tube. The air vent port is communicated with the air vent hole of the needle. The needle and the needle tube are both made of metal materials. The puncture outfit also includes a body. The needle and the needle tube are both fixed on the body and the liquid outlet pipe and the air vent port are both arranged in the body. The puncture outfit has strong puncture ability and saves labor in the operation of inserting into the infusion bottle. Meanwhile, the utility model has a reasonable structure, which can improve the mechanical strength of products and simplify the production process. The utility model has a higher practical value.
Description
Technical field
This utility model relates to technical field of medical instruments, the perforator that uses on particularly a kind of transfusion device.
Background technology
Transfusion is a kind of Therapeutic Method that is widely used.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, after people adopted perforator to substitute transfusion needle and air inlet needle simultaneously, nurse's operation greatly facilitated, and the cost of infusion apparatus product has also reduced.But in existing perforator, because syringe needle and two pipes of needle tubing that set with each other are arranged, general needle tubing adopts plastics to make, and external diameter is thicker, and the operation of inserting infusion bottle is relatively more difficult, and damages bottle stopper easily.
Summary of the invention
The purpose of this utility model is at the difficult problem of the existing insertion infusion bottle operation of existing perforator, and a kind of structure improved perforator is provided, and makes its puncture ability strong, easy to operate.
The purpose of this utility model realizes by following technical proposal: this perforator comprises a needle tubing, a syringe needle, a drain pipe and a blow vent, in the needle tubing is cavity, there is a liquid-through hole its front portion, syringe needle is positioned at needle tubing, syringe needle passes needle tubing and its head stretches out needle tubing, passage is arranged in the syringe needle, the inner chamber of drain pipe communicates with the inner chamber of needle tubing, blow vent then communicates with the passage of syringe needle, also be provided with the air filtration film in the blow vent, above-mentioned syringe needle and needle tubing all adopt metal material to make, and this perforator also comprises a body, syringe needle and needle tubing all are fixed on the body, and drain pipe and blow vent are positioned at body.
In this perforator, the 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 the tube for transfusion; Extraneous air is then entered by blow vent, behind the passage in air filtration film and the syringe needle, enters in the infusion bottle from the outlet of syringe needle.The filtration of air filtration film prevents that objectionable impurities such as airborne microgranule from entering in the infusion bottle.
The outlet of above-mentioned passage is positioned at the sidepiece of syringe needle.Like this, can prevent that pin hole makes the infusion bottle rubber stopper phenomenon generation damaged, that the generation scrap gum is gone forward side by side into the liquid occur when syringe needle inserts infusion bottle, guarantee that patient safety uses.
The needle tubing seat preferably is set between body and needle tubing, and needle tubing and needle tubing seat are fixed together, and the needle tubing seat is fixed on the body.
Compare with common perforator, the utlity model has following advantage:
1, because syringe needle and needle tubing all adopt metal to make, and its product can be done carefullyyer, so the puncture ability is strong, the operation of inserting infusion bottle is more laborsaving.
2, this perforator organically combines syringe needle, needle tubing, drain pipe and blow vent by body, and structure is more reasonable, can improve the mechanical strength of product, simplifies production technology, has higher utility.
3, the outlet of passage is arranged at the sidepiece of syringe needle, prevents the appearance of scrap gum, make the infusion process safety and reliability.
4, this perforator also can insert in the transfusion bag, with the supporting use of transfusion bag because syringe needle and needle tubing connect together.
Description of drawings
Accompanying drawing is the sectional structure chart of the perforator that provides of this utility model.
Among the figure, 1, body; 2, syringe needle; 20, outlet; 3, needle tubing; 30, liquid-through hole; 4, needle tubing seat; 5, drain pipe; 6, blow vent; 7, air filtration film; 8, passage.
The specific embodiment
As shown in the figure, perforator is made up of body 1, syringe needle 2, needle tubing 3, needle tubing seat 4, drain pipe 5, blow vent 16 and air filtration film 7 in the present embodiment.Body 1 is connected as a single entity with drain pipe 5 and blow vent 6, adopts non-toxic plastic to make.Syringe needle 2 is fixed on the body 1, then is provided with needle tubing seat 4 between needle tubing 3 and the body 1.Needle tubing 3 is connected with needle tubing seat 4, and needle tubing seat 4 is fixed on the body 1.
As shown in the figure, blow vent 6 is positioned at the sidepiece of body 1, is provided with one deck air filtration film 7 in the blow vent 6.In the present embodiment, air filtration film 7 adopts hydrophobic membrane to make.
Syringe needle 2 passes needle tubing 3 and its head stretches out needle tubing 3.In the syringe needle 2 is passage 8, and the head of syringe needle 2 has the outlet 20 of passage 8.In the present embodiment, outlet 20 is positioned at the sidepiece of syringe needle 2, can avoid scrap gum occurring in syringe needle 2 insertion process and enter in the medicinal liquid.The cavity that passes through for medicinal liquid is arranged between syringe needle 2 and the needle tubing 3, but the front end of needle tubing 3 and syringe needle 2 tight fits, and the front end of needle tubing 3 is conical.In the present embodiment, it is that material is made that syringe needle 2 and needle tubing 3 adopt rustless steel.Because syringe needle 2 all adopts metal to make with needle tubing 3, and the front end of needle tubing 3 be taper shape, and is so the puncture of this perforator is very capable, more laborsaving during operation.
There is liquid-through hole 30 front portion of needle tubing 3.After this perforator inserted infusion bottle, inner chamber between liquid-through hole 30, needle tubing 3 and the syringe needle 2 and drain pipe 5 formed a medicine liquid channel, enter tube for transfusion for the medicinal liquid in the infusion bottle.Simultaneously, 20 of outlets on blow vent 6, passage 8 and the syringe needle 2 form air duct, make in the air admission infusion bottle, to keep the air pressure balance inside and outside the infusion bottle.
The preferably disposable use of this perforator can be avoided being polluted or cross infection like this.
