Abstract
The utility model relates to a disposable syringe needle. A syringe needle body consisting of an entry needle and a syringe needle base is arranged in a sealed syringe needle sleeve, one end or two ends of the syringe needle sleeve is/are provided with openings, a guide slot is arranged on the wall of the syringe needle sleeve along the length direction, the openings and the guide slot are provided with sealing membranes, a liquid guide tube with one end connected with the syringe needle base is guided out from the end of the syringe needle sleeve, a syringe needle hand on the syringe needle base stretches out of the guide slot and can drive the syringe needle body to move along the guide slot, and a self-locking mechanism is arranged between the syringe needle base and the syringe needle sleeve. The disposable syringe needle is characterized in that disposable syringe needle is realized, the harm caused by repeated use of the syringe needle can be effectively avoided, the self-locking mechanism has a simple design structure, the production cost is low, and the syringe needle is convenient to use, has strong practicability, and can be used in medical fields such as haemospasia, transfusion and dialysis.
Description
Technical field
This utility model relates to a kind of needle for injection, particularly a kind of anti-reusable disposable injection syringe needle.
Background technology
Conventional medical injection needle relatively simple for structure, but it is not functional strong, syringe needle and needle guard are Split type structure, need when using operation needle guard is taken off, syringe needle is all exposed to be contacted with external environment condition, penetrated in the patient body by medical personnel again, meet simultaneously carelessness by chance and also easily medical personnel are damaged, use inadequate health, safety.The transfusion time spent, needle roller only by immobilization with adhesive tape, occurs in syringe needle easily, brings misery to the patient.Can not limit reusing after syringe needle uses, secondary uses and causes easily cross infection, endangers public security.
At present, existing disposable syringe mainly is the design of carrying out for syringe, can destroy after use, prevents from reusing.And having no the relevant report of injection needles head, the special-purpose needle heads such as blood drawing, transfusion, dialysis are still take conventional art as main.
Summary of the invention
The purpose of this utility model is to provide a kind of disposable injection syringe needle that can effectively stop to reuse, use more convenient, safety, health.
The purpose of this utility model is achieved in that the disposable injection syringe needle, comprise the spike body and the pinhead sleeve that are consisted of by entry needle and needle holder, it is characterized in that spike body is positioned at the needle seal headgear, the pinhead sleeve one or both ends are provided with opening, be provided with along its length gathering sill on the syringe needle jacket wall, opening and gathering sill are provided with sealed membrane, the catheter that one end is connected with needle holder is drawn through the pinhead sleeve end, syringe needle handle on the needle holder also can drive spike body and move along gathering sill outside gathering sill stretches out groove, be provided with self-locking mechanism between needle holder and pinhead sleeve.
Described self-locking mechanism is to be made of the latch nook that is arranged on needle holder outer wall and the pinhead sleeve one end inwall.
Be provided with the oblique section for cutting sealed film in syringe needle handle both sides.
Be provided with easy folding line at the syringe needle handle.
Outer wall at pinhead sleeve is arranged with check plate.
The disposable injection syringe needle that this utility model provides, its spike body is arranged in the pinhead sleeve of sealing, along with injection needle constantly outwards advances, needle point is progressively outwards mobile through the end of pinhead sleeve, and can directly penetrate in the human body, outside entry needle can all not be exposed to during injection, thereby the safety and sanitation of guarantee using can prevent effectively that again syringe needle from accidentally injuring other people.The self-locking mechanism that between needle holder and pinhead sleeve, arranges, can after entry needle uses once, spike body be withdrawn in the pinhead sleeve, and the latch nook that the latch nook on the needle holder is entered on the pinhead sleeve is interval, spike body is locked in the pinhead sleeve, can not reuses.Simultaneously the syringe needle handle is fractureed, it can't outwards be advanced, form duplicate protection.Two ends and gathering sill at pinhead sleeve are provided with sealed membrane, guarantee the sealing effectiveness in the pinhead sleeve.When the sealed membrane on the gathering sill can the spike body in pinhead sleeve outwards advances, cut sealed membrane with the oblique section of syringe needle handle both sides, also can be for directly sealed membrane being torn.With easy tear tape, can conveniently tear on the sealed membrane at pinhead sleeve two ends.At pinhead sleeve two symmetrical walls check plate is set, guarantees that the patient when receiving treatment, the problems such as needle roller, dropped stitch does not occur.
Characteristics of the present utility model are: realize the disposable use of needle for injection, can effectively solve syringe needle and reuse the harm that causes; The self-locking mechanism project organization is simple, and production cost is low, and is easy to use, practical; The function of existing traditional syringe needle also has the handling safety health, avoids syringe needle to pollute, and prevents that effectively syringe needle from accidentally injuring other people situation and occuring; Can be used in the medical fields such as blood drawing, transfusion, dialysis, effectively promote medical service level.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is this utility model user mode sketch map;
Fig. 3 is this utility model self-locking state sketch map.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the disposable injection syringe needle mainly is made of spike body and pinhead sleeve 1 two parts, and opening is established at the pinhead sleeve two ends, and the gathering sill 12 that the syringe needle jacket wall is offered along its length, the cross section of pinhead sleeve are circular or semicircle, and present embodiment is semicircle.Spike body is made of needle holder 11 and connected entry needle 2, and the needle holder end is connected with the catheter 7 that is connected with entry needle.Needle holder is provided with syringe needle handle 8, which is provided with easy folding line 10, and both sides are provided with oblique section 9, is used for the sealed membrane 5 on the cutting gathering sill, if sealed membrane is peelable film, also can not establish oblique section.Spike body is positioned at pinhead sleeve, and catheter is drawn from pinhead sleeve one end, and the syringe needle handle stretches out from pinhead sleeve gathering sill 12.The self-locking mechanism that arranges between needle holder and the pinhead sleeve adopts the latch nook 3,4 that cooperatively interacts, is distributed on needle holder outer wall and the pinhead sleeve one end inwall, and be positive latch nook 4 on the needle holder wherein, be latch nook 3 on the pinhead sleeve.But being not limited to this structure, also can be the structure that hook matches with hole slot.Be equipped with the sealed membrane 13,5 with easy tear tape on pinhead sleeve two ends and the gathering sill, guarantee the sealing property of pinhead sleeve, can conveniently tear during use.Can be symmetrically arranged with check plate 6 on the pinhead sleeve outer wall, the planar wall of check plate and semicircle pinhead sleeve is on the same plane.
During use, the sealed membrane on pinhead sleeve two ends and the gathering sill is torn, operation syringe needle handle, entry needle constantly outwards advances, and entry needle shifts out pinhead sleeve and directly penetrates on the human body outward, sees Fig. 2.After injection was finished and pulled up entry needle in the patient body, operation syringe needle handle was withdrawn into entry needle in the pinhead sleeve, and needle holder is withdrawn into self-locking area, and the latch nook of needle holder on pinhead sleeve is hooked in, and finishes self-locking.Simultaneously the syringe needle handle is fractureed, make it can't carry out outside forward operation, see Fig. 3.
