Abstract
The utility model discloses a syringe with medicine itself. The utility model is characterized in that the outside of the needle head 1 is provided with a sealing charge 2, the back of the needle head seat 3 is provided with a chamber 4 for physic liquor. The utility model is provided with a pressurizing unit 5 which is provide with an outer sleeve pipe 7 and a stop cock 8 as a matter of convenient use. The front end of the outer sleeve pipe 7 is provided with an opening 10 which has a semicircular cross section. The chamber 4 is arranged in pressurizing unit 5 through the opening to impel the stop cock 8. The physic liquor expels out from the needle head 1 and the chamber 4 along the needle head seat 3 when the medical personnel press the chamber. The function is same with the ordinary syringe. The utility model stops bringing about the pollution at each link of the operation or cross infection fundamentally, and has the advantage of easy use.
Description
This utility model relates to medical apparatus and instruments, particularly syringe.
The syringe of prior art generally has syringe needle, sleeve pipe and plug.During use,, again medicinal liquid is sucked, give patient injection then through autoclaving.In each operating process, very easily cause cross infection or pollution.For addressing this problem, once designed disposable syringe.Inhaling pollution and the cross infection that medicine process and irresponsibility produce but still exist.
The purpose of this utility model is in order to overcome the shortcoming of said syringe, fundamentally to stop to pollute and cross infection.Design a kind of medicine injection device that carries.
The purpose of this utility model is to realize like this.Injection device comprises syringe needle, needle holder.It is a rubber-like blister cavities that medicinal liquid is housed that a sealing shroud, the back of needle holder are arranged in the outside of syringe needle.
In order to make device of the present utility model practical more, also designed the prelum that is exclusively used in this device.This prelum has a front portion to have the trocar sheath of opening, and a plug is arranged in this trocar sheath, and the end of plug is one to add pressure handle, and a hand-held handle is arranged on the trocar sheath.Its forward opening is the half-open groove that can hold the blister cavities of injection device.
The utility model has the advantages that the medicinal liquid in the blister cavities once injects when manufacturing, fully suitability for industrialized production.Before using, there is not the opportunities for contamination of imbibition repeatedly and operation, easy to use.Can be made into the volume of various dosage, to adapt to different needs.
Description of drawings, accompanying drawing 1 are the structural representations of injection device of the present utility model, and accompanying drawing 2 is structural representations of the prelum of injection device of the present utility model.Figure three is the installation diagrams in the prelum of injection device load map two of figure one.In the accompanying drawings, each serial number name: 1 syringe needle, 2 sealing shrouds, 3 needle holder, 4 blister cavities, 5 prelums, 6 add pressure handle, 7 trocar sheaths, 8 plugs, 9 handles.
Describe this utility model in detail below in conjunction with accompanying drawing.With reference to accompanying drawing 1, syringe needle 1 is the conventional hollow needle of using, and a needle holder 3 is arranged thereafter, has connected one section sealing shroud 2 on the needle holder 3, and this overlaps syringe needle 1 complete closed.The open-part of cover is located at the joint of syringe needle 1 and needle holder 3, does not influence use, is blister cavities 4 in the back of needle holder 3, is filled with medicinal liquid in it, and blister cavities is a totally enclosed cavity, and the medicinal liquid and the external world filled within it are isolated fully.The material of blister cavities 4 can use the rubber-like plastic shaping.Blister cavities communicates through needle holder with syringe needle.
With reference to accompanying drawing 2, be one and aim at the prelum 5 that uses this injection device and design.Have the plug 8 that a trocar sheath 7 and slide within it, the end of plug 8 have one add pressure handle 6 so that the operator in this application of force, the end of trocar sheath 7 has one handle 9, so that the support of operator's hands.Front end at trocar sheath 7 has an opening 10, and the cross section of this opening is a semicircle, is equivalent to the front end of trocar sheath is removed cylinder half.Fill prelum 5 is promptly put in medicine bag chamber 4 by this opening 10 trocar sheath 7 among Fig. 1, at this moment, impose thrust, plug 8 reaches adding pressure handle 6 places.If at this moment the sealing shroud 2 of syringe needle 1 outside is also removed, the medicinal liquid in the blister cavities 4 can be discharged through syringe needle 1 from blister cavities 4 under the effect of extruding force.
Injection device of the present utility model can use separately, use the same with common syringe in the prelum of also can packing into.When injection device uses separately, can reach the purpose of injection, and itself and injection device are then under the extruding of plug 8, the same with ordinary syringe when together using, and reach the purpose of notes with hands extruding blister cavities 4.
Medicinal liquid must be through the approval of medical and health department.
