Abstract
A medical injection needle abrasion device is provided. A motor is arranged on a shell partition; a grinding wheel is fixed on an output shaft of the motor; an upper box body is fixed on the upper part of the shell; the upper box body has a conic internal chamber for placing the sterilized cotton; the lower part of the upper box body has a needle outlet which is communicated with the conic internal chamber; the upper cover of the upper box body has a top cover with a needle inserting hole; a power switch consisting of two elastic metallic pieces is fixed at the bottom plane of the upper box body; the front ends of the two elastic metallic pieces are arranged up and down and are corresponding to the needle outlet; a battery bin is arranged at the bottom cover of the lower part of the shell and is electrically connected with the motor by the power switch. After the injection needle is inserted, the device disinfects in time and grinds the needle blunt to avoid the needle damage the human body and the chance that medical staffs are infected by the virus and the bacilli is reduced, additionally, the needle is efficiently avoided to be reused; the shut-on and shut-down are automatically controlled; the operation is simple, the cost is cheap and the utility model is convenient to be generalized.
Description
Technical field:
The utility model relates to a kind of syringe needle wear device, is used for the sharp-pointed part blunt of syringe needle.
Background technology:
In the medical personnel's of hospital clinical position, bearing a large amount of puncture workings, as intravenous injection, blood sampling, various injections etc., and because of the needlestick injuries chance is many especially, personnel's probability of particularly nursing and handling syringe needle can be bigger.Because the increase of the various infectious diseases of modern society such as hepatitis, AIDS etc., the personnel that carry disease germs increase gradually, the very big composition of its disease is to pass through blood propagation, if and accidentally injured the staff to the patient with the injection needle of crossing, just be easy to make the medical worker infected, increased medical worker's the feared state of mind, institute just seems particularly important so that syringe needle is not easy to stab human body.
Summary of the invention:
The purpose of this utility model provides a kind of syringe needle wear device, can after having played pin, will in time the needle point blunt also be sterilized with the injection needle of crossing, avoid stabbing human body, reduce the medical worker, eliminate their thought misgivings by the chance of virus and bacterial infection.
The purpose of this utility model realizes as follows: motor is housed on the housing, and fixed emery wheel on the motor output shaft, motor are fixed on the dividing plate at housing middle part, and emery wheel is above dividing plate; Housing top is upper cartridge body fixedly, upper cartridge body has one to be used to place the conical internal cavity of aseptic cotton, there is the needle outlet that communicates with the conical internal cavity vertex of a cone upper cartridge body lower end, the position of the corresponding emery wheel off center in needle outlet below, top cover is stamped in the upper cartridge body upper end, has on the top cover and the pin holes of needle outlet on same vertical line; Lower housing portion has the power supply that is electrically connected with motor by power switch.During use, syringe needle is inserted upper cartridge body conical internal cavity part from pin holes, in penetrating the process of aseptic cotton, syringe needle is sterilized soup virus killing that cotton the includes bacterium that disappears, and syringe needle is by the needle outlet positioning and guiding, after passing, needle outlet relies on emery wheel, emery wheel is rotation at a high speed under driven by motor, and behind syringe needle contact emery wheel, tip portion is by the abrasion of grinding wheel rust, then syringe needle is extracted, can be finished.Open the top cover of upper cartridge body upper end, can change aseptic cotton.
Feed opening is arranged on the case partition, and there is discharging opening the lower housing portion side, between feed opening and the discharging opening discharge nozzle is housed, and it is stifled that plug is housed on the discharging opening.Sand grains that emery wheel comes off and syringe needle can be fallen in the discharge nozzle by feed opening by the metal fillings under grinding, and the plug of opening on the discharging opening is stifled, sand grains, metal fillings can be poured out.
Fix two elastic sheet metals on the upper cartridge body bottom surface and form power switch, the front end of two elastic sheet metals is arranged above and below and is corresponding at the needle outlet place, can form automatic switch like this: after syringe needle passes from needle outlet, successively contact with two metal sheets, by syringe needle two metal sheets is electrically connected, be equivalent to switch closure, motor gets electric rotation; After syringe needle ground, when syringe needle was extracted, two metal sheets was in released state, was equivalent to switch and disconnected the stall of motor dead electricity.Folding by plug syringe needle realization switch makes this machine realize automatic switch control.Power switch also can be designed as the mode of sound two metal sheets in the same side: moving plate is in the still top, and when inserting syringe needle, moving plate moves down under the syringe needle effect with still and contacts connection, and after syringe needle was extracted, moving plate resetted and still breaks away from, and realizes outage.
The housing end opening is stifled bottom, and battery compartment is set on the bottom, and battery Hatch Opening loam cake has Cang Gai, opens Cang Gai and just can change battery.
This syringe needle wear device after inserting injection needle, can in time be sterilized and with the needle point blunt, avoids the needlestick injuries medical worker, reduces the medical worker by the chance of virus and bacterial infection, can also prevent effectively that syringe needle is repeated utilization; Insert the syringe needle Auto Power On, extract the syringe needle autostop, control is simple to operate, cheap automatically, is convenient to promote the use of.
Description of drawings:
Accompanying drawing is the structural representation of the utility model syringe needle wear device.
The specific embodiment:
With reference to accompanying drawing, housing 2 outlines are cylinder, can certainly be the revolving body of other cross sectional shape, there is dividing plate 5 at housing 2 middle parts, by screw motor 4 is fixed on dividing plate 5 downsides, motor output shaft passes above the dividing plate 5, fixed emery wheel 6 on the motor output shaft, the center line of motor output shaft departs from housing 2 center lines, housing 2 tops are by the fixing upper cartridge body 9 of screw, upper cartridge body 9 also is a revolving body, upper cartridge body 9 has a conical internal cavity 10, places aseptic cotton in this inner chamber 10, and there is the needle outlet 13 that communicates with conical internal cavity 10 vertex of a cones at center, upper cartridge body 9 lower end, like this on the position of corresponding emery wheel 6 off center in needle outlet 13 belows, the front end of fixing two elastic sheet metals composition power switch, 8, two elastic sheet metals on upper cartridge body 9 bottom surfaces is arranged above and below, and also correspondence is at needle outlet 13 places, and upper cartridge body 9 upper ends are by the top cover 11 that is threaded, top cover 11 is a round, and there is pin holes 12 at top cover 11 centers; Feed opening 14 is arranged on the case partition 5, and housing 2 lower side have discharging opening 16, between feed opening 14 and the discharging opening 16 discharge nozzle 15 are housed, and plug stifled 17 is housed on the discharging opening 16.Housing 2 end openings are provided with battery compartment 19 by screw fixed bottom cover 1 on the bottom 1, be stamped storehouse lid 18 on 19 mouthfuls of the battery compartments.The negative pole of battery connects motor 4 negative poles by lead 3 in the battery compartment 19, the positive pole of battery is connected to switch 8 by lead 3 in the battery compartment 19, be connected to motor 4 positive poles from switch 8 again, be connected lead 3 through banjos 7 connections between anodal and the switch 8, like this when changing emery wheel 6, pull out banjo 7 and make things convenient for separating between upper cartridge body 9 and the housing 2, also can conveniently produce assembling.
