Abstract

The utility model relates to a miniature needle destroyer used for a syringe, which is composed of a rechargeable battery (8), a charging circuit (figure 3), an alternating current transformer (9), electromagnets (12), a fixed electrode (10), a sliding electrode (11), a fusing circuit (figure 4), a needlepoint inserting opening (1), a microswitch (13), an alternating current indicator (3), a direct current indicator (4), a working indicator (2), and a needle storing box (6). The utility model can be used with direct current and alternating current. A function of destroying the needle can be performed by that the needlepoint can be inserted into the needlepoint inserting opening to trigger the microswitch after a disposable sterilized syringe is used; the electromagnets can be attracted to push the sliding electrode, and the needlepoint can be pushed toward the fixed electrode and can contact with the fixed electrode to cause a short circuit; the needlepoint can be melted and is cut off, and the broken needle falls into the needle storing box. The whole process of destroying the needle is shorter than one second.

Description

The miniature spryinge destroying device of syringe

Affiliated technical field:

This is suitable for the novel miniature spryinge destroying device of a kind of syringe spryinge destroying device, especially syringe that relates to.

Background technology:

At present, cause cross-infection or medical personnel and health officer after finishing for the repeated use that prevents disposable sterilized syringe to patient injection, stab because of carelessness during recovery and oneself cause reasons such as cross-infection, country emphasizes necessary mandatory use syringe spryinge destroying device, and the spryinge destroying device that has now gone on the market has two types, a kind of is large-scale spryinge destroying device, fixedly puts a position, and volume is big, power consumption is many, cost is high, price is also high.Large hospital generally can bear, and destroys but also must put together on using again, and does not also remove the danger of stabbing hand when medical personnel wear helmet when collecting from, and price that can't stand great number is all held in general little commune hospital, medical center, uses also inconvenient.Also has a kind of small-sized spryinge destroying device, but because structural principle and to ruin the aciculiform formula different with suitable novel form, the high manufacturing price of cost is also higher, and general little commune hospital, medical center and each ward of large hospital or one of section office's configuration are also held and be can't stand, therefore promote very difficulty.

Summary of the invention:

In order to overcome general spryinge destroying device above shortcomings, novel a kind of miniature syringe spryinge destroying device that provides is provided for this, its volume is little, in light weight, cost is low, utilize the principle that the circuit instantaneous short circuit can fuse metal, cooperate an electromagnet propeller to advance electrode, after the needle point of syringe injected the spryinge destroying device socket, touch switch only needed just used needle point can be destroyed several seconds zero point.This spryinge destroying device adopts AC/DC, under exchange status, and edge work, the limit charging, withdraw from interchange, DC operation, operating voltage all adopt 6 volts of low pressure, to people's safety, cost is low, can mix one on the work car of each Medical Treatment Room or large hospital ward nurse, can entry needle be destroyed in the very first time that syringe uses, can avoid needle point to reuse, stop cross-infection.

The technical scheme that its technical problem that solves the utility model adopts is to establish needle point at the upper surface of shell to insert that mouthful (ruining pin hole) (1), work (fusing) show (2), exchange indication (3), direct current indicates (4) power switch (5) to deposit needle point box (drawer) (6) supply socket (7), in establish chargeable dc-battery (8), AC transformer (9), fixed electrode (10), sliding electrode (11), electromagnet (12), microswitch (13), on circuit board (14), establish charging circuit (Fig. 3) and Zapping circuit (Fig. 4) combines.

After syringe uses, syringe needle point is inserted a mouthful insertion from the spryinge destroying device needle point, during insertion, injecting needle base is toward pressing down the promotion microswitch, connect power supply, electromagnetic actuation is pushed charged sliding electrode to needle point, makes needle point and fixed electrode, the sliding electrode contact, the locus distance of sliding electrode and fixed electrode is very short, be in that needle point is melted by Short-Circuit High Current between two electrodes, the promotion moment that adds electromagnet will be injected needle point and be cut off, and needle point falls into deposits box for needle or pin, at this moment power supply disconnects, take out syringe, get final product the safety area upper jacket, put the syringe gathering-device into.Deposit the needle point of box for needle or pin and can pour the dedicated container that has thimerosal into, reclaim.So only need spend more medical personnel just can destroy needle point like a cork less than one second time.

This is suitable for novel beneficial effect, and disposable sterilized syringe in the very first time is destroyed entry needle after using, and helps protecting medical personnel's safety, avoids cross-infection, hits illegal illegal activities of recycling.Because easy and simple to handle, quick, production cost is little, in light weight than the end, volume, it is very easy to promote.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified

Fig. 1 is shell of the present utility model, outer surface figure

Fig. 2 is the schematic diagram of embodiment of the present utility model

Fig. 3 is a charging circuit schematic diagram of the present utility model

Fig. 4 is work of the present utility model (fusing) circuit theory diagrams

The specific embodiment:

In Fig. 1 and Fig. 2, circumscripted power line is connected with supply socket (7) interface, and charging circuit (Fig. 3) and voltage are that the rechargeable cell (8) of 6V is connected, and connect external AC power supply, can carry out work and charging, at this moment exchange indicator lamp (3) and ignite.When entry needle (15) inserts socket (1), promote microswitch (13), microswitch (13) is connected, electromagnet (12) adhesive, promote sliding electrode (11), sliding electrode (11) is pushed entry needle to fixed electrode (10), at this moment relay indicating light (2) ignites, because two interelectrode needle points are apart from weak point, resistance causes short circuit for a short time, the big electric current of short circuit melts injection needle (15), electromagnet (12) is passed to the thrust of sliding electrode (11), and moment is cut off entry needle (15), and short circuit stops, relay indicating light (2) extinguishes, and the spryinge destroying device function is finished.During DC operation, remove AC power, direct current indicator lamp (4) ignites.Working procedure and alternate current operation program are identical later on, ruin the pin function and finish.Cut needle point falls and is depositing box for needle or pin (6) lining, when having some, extracts out and deposits box for needle or pin, and disposable being poured on of needle point concentrated destruction in the container that fills disinfectant.
