Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a take lid device safety type syringe.
Background
The existing domestic safe syringes are mostly of a loop type and a self-destruction type, only solve the problem of needle stick injury of the existing medicines, and are disposable. In clinical work, particularly in domestic medical environments, many medicines need to be prepared at present or be administered for a few times after being prepared. The use of self-destructive syringes can increase the medical costs for patients and increase the generation of social medical waste; although the back-cover type injector can be continuously inserted and pulled for use, the risk that a back-cover cap outside the needle head falls off is also generated, the possibility of needle stick injury is increased, and due to repeated insertion and pulling of the needle head and the needle cylinder nipple, the fitting degree is reduced, and the risk of infection is increased. Therefore, the injector which can keep the needle head and the syringe and reduce the infection risk is lacked.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a safe injector with a cover device, which is characterized in that on the basis of keeping the injector needle head and the needle cylinder nipple, a cover device is fixedly connected with the side wall of the needle cylinder nipple through a connecting wire, the device is divided into a cover cap and a knob, after medical staff sucks the medicine, the knob partially blocks a pintle at the rear end of the needle head which is taken down, and the cover cap covers the needle cylinder nipple, so that the asepsis of the medicine in the needle cylinder can be ensured, and the risk of needle stick injury in the process of multiple medicine use can be avoided; the asepsis of the needle can be ensured, and the patient can use the same syringe to suck the same medicine when necessary, thereby avoiding the waste of medical articles.
The purpose of the utility model is realized through the following technical scheme: a safety syringe with a cover device comprises a syringe needle, a syringe body and the cover device;
the upper pintle of the syringe needle is detachably connected with the upper nipple of the syringe body;
the cover device comprises a cover cap and a knob; the cap and the knob are connected in a separable manner, and the cap is fixedly connected to the nipple of the injector body through a connecting line;
the size of the cap is matched with that of a nipple on the injector body;
the size of the knob is matched with the size of a pintle on the syringe needle.
Further, the material of the cap is the same as the material of the nipple on the syringe body.
Further, the material of the knob is the same as that of the needle bolt on the syringe needle.
Further, a needle cap is arranged on the syringe needle.
The utility model has the advantages that: the utility model provides a pair of cover device, which is not available in the prior safe injector. Most of the prior safe syringes aim at solving the problem of needle stick injury caused by the back cover of the back cover cap outside the needle head, have small application range and can not be reused under special conditions, thereby increasing the risk of medical waste pollution. Because operational environment and the particularity of work content, anesthesia branch of academic or vocational study medical staff need give the liquid medicine that has disposed a small amount of many times according to the operation demand, the utility model discloses an on prior art's basis, replace the syringe needle with the lid device, the effectual needle that has avoided many times plug syringe needle to arouse hinders the risk, and the lid device more laminates with the cylinder nipple, has effectively avoided because the leakproofness of syringe needle and cylinder nipple is relatively poor, the pollution risk of increase. The knob blocks the back end of the syringe needle which is taken off, the syringe needle is kept properly, and the syringe needle can be reused within a specified time according to the requirement of hospital feeling.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the single embodiment in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the present invention provides a safety syringe with a cap device, which comprises a syringe needle 1, a syringe body 2 and a cap device 3;
the needle bolt 4 on the syringe needle 1 is detachably connected with the nipple 5 on the syringe body 2; the syringe needle 1 is provided with a needle cap 8.
The cover means 3 comprises a cap 6 and a knob 7; the cap 6 and the knob 7 are in separable connection in a thread form, and the cap 6 is fixedly connected to the nipple 5 of the injector body 2 through a connecting line;
the size of the cap 6 is matched with that of the nipple 5 on the injector body 2; the cap 6 is made of the same material as the nipple 5 of the syringe body 2.
The size of the knob 7 is matched with that of the pintle 4 on the syringe needle 1; the material of the knob 7 is the same as that of the pintle 4 on the syringe needle 1.
The utility model adds a cover device 3 on the 5 side walls of the nipple of the needle cylinder on the basis of the original common injector or the loop-back safety injector. The device consists of two parts, namely a cover cap 6 and a knob 7. After the drug aspiration is complete, the needle is either stored or discarded as required by the patient. When the syringe needs to be stored, the knob 7 is separated from the cap 6, the rear end pintle 4 of the taken syringe needle 1 is blocked by the knob 7, and the cap 6 is covered on the nipple 5 of the syringe. Therefore, the sterility of the medicine in the needle cylinder can be ensured, the risk of needle stick injury in the process of multiple-time medicine taking is avoided, the condition that the same medicine is used by the same injector of the same patient in a short time is ensured, and redundant operation is avoided. Is suitable for the situation that the medicine is used by the existing matched patient in clinical work, in particular to the use of narcotic in operation. Meanwhile, the asepsis of the needle head of the syringe can be ensured, and the patient can use the same syringe to suck the same medicine when necessary, thereby avoiding the waste of medical articles.
In the case of all the syringes in clinical use at present, the inner diameter of the rear end of the syringe needle 1 (i.e., the junction with the syringe nipple) is the same regardless of the type of syringe. Therefore, the cover device 3 designed by the utility model can be suitable for all syringes, and is very economical and practical.
The utility model provides a safe type syringe use is as follows: the cover device 3 provided by the utility model can be connected with a cover device 3 at the nipple 5 of the traditional syringe cylinder when the syringe is processed, the material is consistent with the cylinder, thus forming a safe syringe with a cover device, and after the liquid medicine is pumped by the needle head, if not, the needle head can be directly discarded; if the medicine needs to be sucked, the knob 7 can be used for blocking the rear end pintle 4 of the removed needle, and then the cover cap 6 is covered at the nipple 5 of the injector. When the injector is needed for administration, the cap 6 is unscrewed for injection.
The above-mentioned embodiments are provided for explaining the present invention, not for limiting the present invention, and any modifications and changes made to the present invention are within the spirit of the present invention and the scope of the claims and fall within the scope of the present invention.
