Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of telescopic anti-pricking wound syringe.
Background technology
Current syringe, the piston mainly include syringe, coordinating with syringe and these parts of push rod be connected with piston.Medical personnel are moved by push rod push-and-pull piston, realize making up a prescription or the operation such as injection.
But, inventor finds, the syringe of current structure, syringe needle, pinhead sleeve and syringe are split-type design, when medical personnel use, need first pinhead sleeve to be taken off, and then carry out making up a prescription or the operation such as injection, after end of operation, in order to avoid external environment is to the pollution of syringe needle, or in order to avoid syringe needle environment to external world, need medical personnel to be again enclosed within syringe needle by pinhead sleeve.
In above-mentioned needle of infusion cover process, because the size of syringe needle and pinhead sleeve is all less, the situation of cover dislocation is returned in frequent appearance, namely, medical personnel, when being enclosed within syringe needle by needle of infusion, due to para-position inconvenient between pinhead sleeve and syringe needle, make back cover process stagger, causing pinhead sleeve to be inconvenient to be enclosed within syringe needle, is first stopped over the working time; But the more important thing is, due in needle of infusion cover process, be medical personnel's hand-held needle cover, so when pinhead sleeve and syringe needle stagger, the hand of very likely stabbing medical personnel is caused infection by syringe needle.
So based on above-mentioned, needing one at present badly can effectively prevent from stabbing medical personnel, and return overlap syringe easily.
Summary of the invention
The purpose of this utility model is to return cover inconvenient operation for current syringe, and returns cover process and easily stab the deficiency of medical personnel's hand, provides one effectively to prevent from stabbing medical personnel, and returns and overlap syringe easily.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of telescopic anti-pricking wound syringe, include syringe, be arranged on the syringe needle on described syringe and be arranged on described syringe and described syringe needle is coated on interior pinhead sleeve, described pinhead sleeve is fixedly installed on described syringe, described pinhead sleeve is telescopic pinhead sleeve, the lower end of described pinhead sleeve is opening-wide state, when described pinhead sleeve foreshortens to the most in short-term, it is outside that syringe needle is exposed to described pinhead sleeve, when pinhead sleeve is nature elongation state, in described syringe needle is coated on completely by described pinhead sleeve.Syringe of the present utility model, under normal condition, pinhead sleeve is nature elongation state, medical personnel carry out making up a prescription or injection operation time, directly by syringe needle and syringe needle inserting to medicine bottle or patient injection site, because pinhead sleeve is telescopic pinhead sleeve, when pinhead sleeve contacts with medicine bottle or patient injection site, along with the movement of syringe, pinhead sleeve due to medicine bottle or patient injection site stop and shorten gradually, simultaneously, make, syringe needle gradually extended needle inserting enters the injection site of medicine bottle or patient, when syringe needle inserts medicine bottle or patient injection site's sufficient length, can carry out making up a prescription or injection work, after making up a prescription or injection work complete, the injection site of medicine bottle or patient extracted gradually by syringe needle, now, along with extracting of syringe needle, pinhead sleeve extends gradually, when syringe needle is extracted completely, in syringe needle is coated on by pinhead sleeve recovery naturalness again completely, by the anti-pricking wound syringe of the application, after making up a prescription or injection work complete, in syringe needle is coated on by pinhead sleeve automatically, external environment condition contaminated pinhead or syringe needle is avoided to pollute external environment condition, and this process does not need medical personnel deliberately to complete, so greatly facilitate the use of syringe, what is more important, medical personnel no longer need to be enclosed within syringe needle with needle of infusion, directly avoid the danger of needle sting medical personnel.
As preferably, described pinhead sleeve is transparent material.Pinhead sleeve is set to transparent material, and medical personnel can know the position seeing syringe needle, in use, facilitate syringe needle para-position to insert medicine bottle or patient.
As preferably, described pinhead sleeve includes the fixed part be fixedly connected with syringe, and to slide the sliding part arranged relative to described fixed part.Pinhead sleeve comprises fixed part and sliding part, is realized elongation and the shortening of pinhead sleeve by the cooperation of fixed part and sliding part.
As preferably, described pinhead sleeve also includes elastic component, and described elastic component provides pressure for described sliding part, makes described pinhead sleeve in its natural state in elongation state.By arranging elastic component, make when naturalness, pinhead sleeve is in syringe needle is coated on by elongation state.
As preferably, the cavity holding described sliding part is provided with in described fixed part, one end of described sliding part is slidably arranged in described cavity, the other end reaches described containment portion, end in cavity is provided with stops to described sliding position, shown fixed part is provided with the seam matched with described stops, and described elastic component is arranged in described cavity.
As preferably, the open end of described pinhead sleeve is provided with the sealing member of this open end of sealing.By arranging sealing member, make the cavity for sealing in pinhead sleeve, syringe needle is avoided to be polluted by external environment condition when not using, in use, sealing member is taken off, use gap or after sealing member is covered again, avoid the syringe needle being stained with medicinal liquid to be subject to outside contamination with this, or pollute external environment.
As preferably, described sealing member is sealing film.
As preferably, described sealing member is fixedly connected with the open end of described pinhead sleeve.Because sealing member is sealing film, sealing film is fixedly installed on the end of sliding part away from stops, in syringe needle extended needle cover process, the direct puncture through seal part of syringe needle, so make in use, can not need to take off sealing member, facilitate medical personnel to operate; And, because sealing film itself has certain elasticity, and the diameter of syringe needle own is less, so when syringe needle is coated on interior by pinhead sleeve again, namely, when syringe needle departs from sealing film, the pin hole that sealing film stays is less, so, when pinhead sleeve is coated on syringe needle again, sealing film still can play sealing function.
As preferably, described elastic component is spring.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, exempt from external environment condition contaminated pinhead or syringe needle pollution external environment condition, and this process does not need medical personnel deliberately to complete, so greatly facilitate the use of syringe;
2, medical personnel no longer need to be enclosed within syringe needle with needle of infusion, directly avoid the danger of needle sting medical personnel.
