Abstract
The utility model provides an air inlet type puncturing device used on a transfusion device. The utility model comprises an outer sleeve, and the front end of the outer sleeve is provided with a needle head. The head part of the needle head extends out of the outer sleeve, and the lateral part of the outer sleeve is provided with a blow vent which is communicated with the needle head. An air filtering film is arranged in the blow vent, and the front end of the outer sleeve is tapered and is provided with a liquid through hole. The air inlet type puncturing device has the characteristics of portable operation and strong puncturing force. When the utility model is used, an air inlet pipe of the existing transfusion device is omitted, and a nurse's operational procedure is simplified.
Description
This utility model relates to a kind of medical device, the puncture outfit that uses on particularly a kind of transfusion device.
In transfusion device, puncture outfit is a key element that connects tube for transfusion and infusion bottle.When the nurse uses in reality, puncture outfit need be inserted in the infusion bottle.Existing puncture outfit is thinner, insert easily, but the transfusion progress is slow.For this reason, national departments concerned has been done correction to standard, requires to use thicker puncture outfit.Because puncture outfit generally adopts plastics to make, just be difficult to after the size chap insert in the infusion bottle, directly influence the normal use of transfusion device.
The purpose of this utility model is at the problems referred to above, and a kind of air admission type perforator light, that puncture force is strong of operating is provided.
The purpose of this utility model is achieved in that this air admission type perforator comprises piped overcoat, the rear end of overcoat is used for and the tube for transfusion socket, a syringe needle is set in the front end inner chamber of overcoat, the head of this syringe needle stretches out overcoat, the sidepiece of overcoat is provided with blow vent, and blow vent communicates with syringe needle, and the air filtration film is set in the blow vent, it is conical that the front end of overcoat is, and be provided with liquid-through hole.Syringe needle of the present utility model is generally thinner, and adopts rustless steel to make, and has stronger penetration power.Because it is conical that the front end of overcoat is, so the overcoat front end also can enter in the infusion bottle with syringe needle.In this air admission type perforator, the liquid-through hole of overcoat front end and the inner chamber of overcoat form a fluid-through tube road, and the medicinal liquid in the infusion bottle is flowed in the tube for transfusion.Air is then entered in the infusion bottle through syringe needle by blow vent, keeps the infusion bottle inside and outside air pressure balance.Air filtration film on the blow vent both can prevent that the infusion bottle inner liquid medicine from flowing out, and played filtration efficiently to the air that enters in the bottle again.
This utility model is because the overcoat front end is provided with syringe needle, so operation is light, puncture force is strong; At blow vent the air filtration film is set, can omits the air inlet pipe in the existing transfusion device, and simplify nurse's operation sequence, have higher utility.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the sketch map of the air admission type perforator that provides of utility model.
Among the figure, 1, syringe needle; 2, overcoat; 3, blow vent; 4, liquid-through hole; 5, air filtration film; 6, gag.
As shown in the figure, this air admission type perforator comprises syringe needle (1) and overcoat (2).In the present embodiment, syringe needle (1) adopts rustless steel to make, and overcoat (2) adopts plastics to make.Overcoat (2) front end is provided with several liquid-through holes (4), and overcoat (2) sidepiece is provided with blow vent (3), and blow vent (3) is communicated with syringe needle (1) is terminal.Air filter membrane (5) is arranged in the blow vent (3), and on the blow vent (3) gag (6) is set also.The effect one of gag (6) is in order to protect air filtration film (5), the 2nd, and when not needing to use intake method, gag (6) can be taken off and directly use.This air admission type perforator can puncture glass infusion bottle, plastic infusion bottle, plastics liquid bag and the defeated bags of blood etc. of different size.
Claims (2)
1, a kind of air admission type perforator, comprise piped overcoat (2), the rear end of overcoat (2) is used for and the tube for transfusion socket, it is characterized in that in the front end inner chamber of described overcoat (2) syringe needle (1) being set, the head of this syringe needle (1) stretches out overcoat (2), and the sidepiece of overcoat (2) is provided with blow vent (3), blow vent (3) communicates with syringe needle (1), and air filtration film (5) is set in the blow vent (3), and it is conical that the front end of overcoat (2) is, and be provided with liquid-through hole (4).
2, air admission type perforator according to claim 1 is characterized in that also being provided with on the described blow vent (3) gag (6).
