Description
Technical field
A kind of syringe is the utility model is related to, is specifically a kind of antipollution syringe of nursing section.
Background technology
With the fast development of China's economy, the medical industry in China has also obtained rapid progress, although more and more
Novel medical device obtained extensive utilization, but traditional medical instruments are yet using.
Syringe is a kind of very traditional medical instruments, and syringe is by the foraminate syringe of front end band and matching
Piston core pin composition, for by a small amount of liquid or its be injected into region that other methods can not approach or from those places
Extraction, either gas is sucked liquid or gas when core bar is pushed into liquid from syringe front end aperture when core bar is extracted
Body is extruded, and modern syringe is there is the defects of angle, such as when inject again, and especially New nurse easily produces hand shaking
Situation, cause injection accuracy reduction, simultaneously because the piston rod of syringe be need be frequently inserted or extract, this
Sample is easy for causing piston rod to be contaminated and then pollutes the parenteral solution in syringe.
For this reason, being directed to problem proposed in the above background technology, those skilled in the art propose a kind of new nursing
Section's syringe.
Utility model content
The purpose of this utility model is to provide a kind of nursing section with antipollution syringe, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical solution：
A kind of antipollution syringe of nursing section, including syringe, piston, piston rod and injection needle, in the syringe
Piston is equipped with, the outside diameter of piston is slightly lower than the internal diameter of syringe, and the left end of piston is provided with piston rod；The piston rod
One end be fixedly connected with the piston, the other end of piston rod is pierced by syringe and is fixedly connected with handle；Between the handle and syringe
Protective case is provided with, with being fixedly connected on the inside of handle, the other end of protective case and the tail end of syringe are fixed for one end of protective case
Connection, protective case are made of elastic material；The upper end of the piston rod is provided with the first groove, and syringe is provided with recessed by caudal part
Groove, is provided with shaft in groove, and the both ends of shaft are fixedly connected with the side wall of syringe, is rotated in shaft and is provided with gear, gear
On be provided with the second groove；Injection needle is provided with the right side of the syringe, injection needle inside syringe with connecting, injection needle
On slidably connect circular ring shape sliding block, disinfection sponge is fixedly connected with the right side of circular ring shape sliding block, circular ring shape sliding block is equal vertically
Even that four fixed links are distributed with, fixed link is fixedly connected with circular ring shape sliding block；The syringe is uniformly distributed circumferentially close to right end
There are four fixed blocks, fixed block is fixedly connected with the lateral wall of syringe, and four fixed blocks and four fixed links correspond.
Further, the maximum length of the protective case is less than the length of piston rod.
Further, second groove and the first groove cooperate.
Further, it is described to be each respectively connected with adjustable spring between fixed block and every fixed link.
Compared with prior art, the utility model can effectively prevent sky due to being provided with protective case between handle and syringe
Bacterium in gas enters in syringe and the parenteral solution of syringe is polluted, while is also prevented from the hand of medical staff to piston
Bar pollutes, simultaneously because being cooperated using the first groove on the second groove and piston rod of gear, when injection
Wait, stability that can be when directly balladeur train can effectively reduce injection, the precision of injection is improved, in the process of injection
In, when injection needle penetrates patient skin, disinfection sponge will be produced with the skin contact of patient when effectively drawing acupuncture treatment
Blood or other festers, prevent from polluting the body of patient, due between each fixed block and every fixed link
Connected by adjustable spring, so depth disinfection sponge of having an acupuncture treatment all can effectively be contacted with the skin of sufferer.
Brief description of the drawings
Fig. 1 is the structure diagram of the antipollution syringe of nursing section.
Fig. 2 is the top view of the antipollution syringe of nursing section.
Fig. 3 is the right view of the antipollution syringe of nursing section.
Embodiment
The technical solution of this patent is described in more detail with reference to embodiment.
Please refer to Fig.1-3, a kind of antipollution syringe of nursing section, including syringe 14, piston 7, piston rod 15 and note
Syringe needle 9 is penetrated, piston 7 is equipped with the syringe 14, the outside diameter of piston 7 is slightly lower than the internal diameter of syringe 14, a left side for piston 7
End is provided with piston rod 15；One end of the piston rod 15 is fixedly connected with piston 7, and the other end of piston rod 15 is pierced by syringe 14
It is fixedly connected with handle 1；Protective case 2, one end of protective case 2 and the inner side of handle 1 are provided between the handle 1 and syringe 14
It is fixedly connected, the other end of protective case 2 is fixedly connected with the tail end of syringe 14, and protective case 2 is made of elastic material, protective case 2
Maximum length be less than piston rod 7 length, so play a spacing effect, prevent whole of piston rod 7 out of syringe 14
Extraction；The upper end of the piston rod 7 is provided with the first groove 3, and syringe 14 is provided with groove 16 by caudal part, is set in groove 16
