Description
Technical field
This utility model belongs to a kind of injector for medical purpose, specifically, is a kind of double syringe with two needle tubings.
Background technology
Along with development of life science, improve quality of life and become the link of focusing on care for the people.For the extremities joint pathological changes, for example: osteoarthritis, degenerative osteoarthritis etc., can adopt hyaluronic acid sodium to carry out the articular cavity perfusion; thereby articular cavity is played effects such as lubricated, protection; alleviate the patient suffering, delay operating time, be subject to people's attention gradually.Pour into and carry out articular cavity at present, generally need earlier empty needle is thrust articular cavity, aspirate the joint fluid that may exist repeatedly, after the affirmation articular cavity does not have tangible joint fluid, extract needle tubing, keep somewhere syringe needle, the hyaluronic acid sodium syringe is connected with syringe needle, inject hyaluronic acid sodium.This operation needs secondary plug needle tubing, has brought the risk of pollutions such as antibacterial, and this will bring serious consequence to the joint, and this inconvenient operation, relatively bother not possessing empirical doctor.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of can pour into the disposable double syringe that carries out imbibition and injection that syringe needle is thrust in the art at articular cavity.
The technical solution of the utility model is as follows: a kind of double syringe, be incorporated with piston and push rod from the needle tubing upper end, this push rod is positioned at needle tubing one end and connects piston, be positioned at needle tubing and be externally connected with push pedal, its key is: described two needle tubings are fixed together side by side, two needle tubing lower ends are connected with same switching valve, the valve body of this switching valve has three interfaces, first interface wherein, second interface is symmetricly set on the valve body, and communicate with two needle tubings respectively, described the 3rd adapter is set with syringe needle down, the 3rd takes over centrage passes first interface, the mid point of the second interface line of centres, and with first interface, the second interface line of centres intersects vertically, have passage in the spool in the described switching valve, this passage is made up of crosspiece and vertical section, and crosspiece and a vertical section the inner are connected and communicate, and rotating described spool can be communicated with one of them of two needle tubings with syringe needle.In the time of need taking out joint fluid, rotational valve core is communicated with the needle tubing that extracts with syringe needle, and then the needle tubing that rotational valve core will be equipped with liquid medicine is communicated with syringe needle, and liquid medicine is injected.
The valve body of above-mentioned switching valve is a cylindrical shape, and this valve body is positioned at two needle tubing junctions, and is structure as a whole, and first interface in the described valve body, second interface are positioned at two needle tubings.Better combine with needle tubing, valve body also can with two needle tubing integrated through injection molding.
Above-mentioned valve body openings end is incorporated with columniform spool, and this spool is positioned at the outer end of valve body and is horizontally arranged with handle.Be convenient to finger and move rotation, change.
Piston in above-mentioned two needle tubings has and the suitable circular arc cutaway of needle tubing inner valve body separately.Piston can be shifted the pipe end onto, when injection liquid medicine, the liquid medicine in the needle tubing can be drained.
Beneficial effect: this utility model can articular cavity pour in the art disposable syringe needle is thrust articular cavity after, finish the action of drawing liquid and injection; The pollutions such as antibacterial of having avoided secondary plug syringe to bring, and simplified the step of this operation.Repeatability, strong operability.
