Abstract
The invention discloses a protective device for a medical needle. The protective device is characterized by comprising a shell and a clamp arranged in the shell, a first opening for a medical needle tube body to penetrate through is formed in one end of the shell, the clamp is in an inverted-V shape, the cuspidal part of the clamp in the inverted-V shape makes contact with the upper surface in the shell and is provided with a cutter, and a second opening for a head of the medical needle to penetrate through is formed in a supporting leg on one side of the clamp. The protective device can bend the needle point in a pressing mode to destroy the needle point, and as the tail end of the shell and the protective needle point of the clamp are not exposed, harm to people is avoided.
Description
Technical field
The present invention relates to a kind of medical needle preventer, belong to technical field of medical instruments.
Background technology
Medical needle, as hypodermic needle, biopsy needle, intravenous introducer, trocar, seal wire, thoracentesis needle etc., these become dangerous goods can be stained with medicine or patient's pathogen with it after use after, and due to unexpected too numerous to enumerate by these cases of stinging with the apparatus of syringe needle, in order to avoid stab by this type of contaminated thorn part or therefore and infect health risk, more existing preventers in prior art, but more existing preventer protection not in place, often also likely suffer secondary injury.
Moreover, existing multiple medical needle is disposable, use the rear pin that simply puts to emit and just abandon immediately, because pin emits and insecure, also can damage the staff of these medical wastes of process, even some lawless person reclaims these medical needles abandoned again, potential safety hazard is larger, prior art does not also find the preventer more thoroughly for this situation, is about to the syringe needle after using and thoroughly damages, can not only avoid stabbing the recycling that yet can prevent person who is ambitious or tenacious of purpose.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of medical needle preventer, and this apparatus structure is simple, can effectively avoid because fortuitous event needle point is to the injury of medical personnel or related personnel.
For solving the problem, the technical solution used in the present invention is:
A kind of medical needle preventer, comprise housing and be placed in the clip in housing, described shell one end has the first opening passed for medical needle body, described clip is inverted V-shaped, the inverted V-shaped pointed portion of described clip contacts with described enclosure interior upper surface, the inverted V-shaped pointed portion of described clip is also provided with a cutting knife, and the leg of described clip side is provided with the second opening passed for medical needle syringe needle.
Preferably, described housing bottom is provided with boss, and described boss is positioned at immediately below described cutting knife.
Preferably, described boss end has a groove.
Preferably, described cutting knife comprises the cutter portion and filling portion that are positioned at end position, is filled with implant in described filling portion.
Preferably, described clip is metal rigid clamp.
Preferably, the described housing other end arranges a baffle plate, and described baffle plate has elasticity in the longitudinal direction.
The beneficial effect that the present invention reaches:
After medical needle uses, preventer of the present invention is enclosed within the head of medical needle, the syringe needle of medical needle enters clip inside by the second opening, then position is adjusted, needle point is placed between cutting knife and boss, by pressing housing tail end, (the first opening position is housing forward end, the housing other end of opposite first open is tail end), housing meeting compression clip, clip with cutting knife by bending of needlepoint by pressure, destroy syringe needle with this, simultaneously because the protection needle point of housing tail end and clip also can not be outside exposed, avoid and people is damaged;
Cutting knife comprises cutter portion and filling portion, first uses cutter portion by bending of needlepoint by pressure, and needle point is blocked by the implant then in filling portion, has both prevented leaking of residue in needle tubing, has also thoroughly damaged needle point, avoid stabbing people and being recovered.Even if pole in particular cases this preventer comes off from medical needle, needle point also can not work the mischief.
Accompanying drawing explanation
Fig. 1 be in embodiment medical needle and preventer assemble after structural scheme of mechanism;
Fig. 2 is the structural representation of preventer in Fig. 1;
Fig. 3 is the structural representation of cutting knife in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As Figure 1-3, a kind of medical needle preventer, the clip 2 comprising housing 1 and be placed in housing, housing 1 one end has the first opening 3 passed for medical needle body 8, and housing 1 other end arranges a baffle plate 7, and baffle plate 7 has elasticity in the longitudinal direction.Clip 2 is inverted V-shaped, and the inverted V-shaped pointed portion of clip 2 contacts with enclosure interior upper surface, and the inverted V-shaped pointed portion of clip 2 is also provided with a cutting knife 4, and the leg of clip 2 side is provided with the second opening 5 passed for medical needle syringe needle.
Particularly, be provided with boss 6 bottom housing 1, boss 6 is positioned at immediately below cutting knife 4, and boss 6 end has a groove 61.When bending to needle point, boss 6 can play certain supporting role to syringe needle, and more convenient cutting knife 4 bends.
Cutting knife 4 comprises the cutter portion 41 and filling portion 42 that are positioned at end position, is filled with implant in filling portion 42.In use, first use cutter portion 41 by bending of needlepoint by pressure, needle point is blocked by the implant then in filling portion 42, has both prevented leaking of residue in needle tubing, has also thoroughly damaged needle point, avoid stabbing people and being recovered.In the present embodiment, implant is viscous silica gel, is namely with sticking silica gel.
More specifically, clip is metal rigid clamp.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
