Description

The mancarried device that is used for destroying needles

The invention relates to the modifying device that is used for destroying safely and effectively used hypodermic needle.

The background of invention

Used hypodermic needle is the residual thing that is potentially dangerous often, and such as having HIV, " blood of hepatitis B or other infectious disease because the people's who attempts to handle them skin may be stabbed in the tip of injection needle, has many devices to can be used for destroying needles.Equipment is destroyed in some use by fire in this class device.The equipment that destroys by fire produces electric current and comes destroying needles; Some uses compression failure equipment, and compression failure equipment grinds the shell with compression failure injection needle and syringe; Sometimes use equipment and the compression failure equipment of destroying by fire simultaneously.

Such as, authorize to disclose a kind of injection needle in people's such as Kohl No. the 5th, 076,178, the United States Patent (USP) and destroy device by fire.A carrier unit has been pushed in the insertion of injection needle to be destroyed open, above-mentioned carrier unit and power supply coupling, and power supply is sent into injection needle to high-tension current by the carrier unit.Yet " motion of carrier is restricted, can not attempt to destroy by fire the total length of a long injection needle to guarantee the operator in once-through operation, and such operation has exceeded the limitation of capacity of power." similar to the disclosed device of people such as Kohe; that there are such problem in other device as the device of authorizing described in No. 4,628,169, Ch ' ing-L ' ung United States Patent (USP); promptly require the user that injection needle is sent in the equipment carefully, to guarantee the destruction of injection needle.Authorize the United States Patent (USP) the 4th of Spinalo, 877, disclose a kind ofly by the self-powered device for the rechargeable battery of choosing in No. 934, similarly this device also requires in the injection needle feeder that the user shortens length gradually so that destroy the electric current destroying needles by fire.Like this, use the device of Spinello or Ching-Lung, cause the only part of destroying needles of hasty or careless user probably, and stay dangerous " stub (stub) ".

Because injection needle has many different sizes, it is complicated more that the above-mentioned operation that injection needle is carefully sent into becomes.If injection needle to be destroyed is long, apparatus for destroying or can not produce enough electric currents with complete destroying needles, or destroy and need for a long time.Similarly, if injection needle to be destroyed is long, the interelectrode distance of apparatus for destroying of destroying type by fire is perhaps excessive, thus the loop of injection needle between can't closed electrode.Moreover, often use this device possibility sacrificial electrode, electrode is further separated, perhaps make electrode when destroying needles, cover last layer " slag " (slag).Like this, electric current will not flow, perhaps only be off and on from electrode stream to injection needle, make partly or entirely being kept perfectly of injection needle like this.

And then, although injection needle fully destroyed, the material that comes from injection needle or syringe may be remaining within apparatus for destroying be arranged.Therefore, authorize the 4th, 961, No. 541 explanations of United States Patent (USP) of Hashimoto: " can when destroying operation, remover be sprayed to syringe ".Yet it is consuming time spraying each syringe, and passes out of mind probably under the pressure of other task.Moreover, in the destruction of injection needle, be provided with the airborne measure of eliminating, do not have suitable to prevent measure or/and enough fast destruction process, airborne cause of disease may be before destroying, among or leave the entry needle of sky afterwards.

Moreover for above-mentioned arbitrary device, the user obviously must be carried to injection needle in this device and ruin with marketing.This activity has increased such danger, and promptly medical worker or other people may stab themselves before injection needle is destroyed.Authorize the United States Patent (USP) of Wallace etc. and recognize that collecting used injection needle ruins the serious problem of bringing with marketing for the 5th, 046, No. 669.People such as Wallace thereby be provided with the processing unit that a collector unit and is positioned at central authorities, it is fragment with injection needle is disconnected, and the plastic casing of melting injection device.

Yet, comparatively it is desirable to have so a kind of compactness, portable device, this device can, such as, can be moved to getting the blood place or planting the vaccine place away from health care facility, perhaps can be included within the bigger medical facilities and transport by a nurse or a medical orderly who makes an inspection tour the ward, yet except the Spindlo device of " self-powered ", there is no real compactness and cheap apparatus for destroying, as if but the device of Spinello only is a destroying needles progressively, and can not prevent distributing of airborne cause of disease.In contrast, many apparatus for destroying have been equipped a lot of accessories, such as the transformer of the heaviness that is used for being coupled with main power source, perhaps are used for the Infrared Detectors of actuation gear, and this has increased the complexity and the expense of instrument.For many users, this complexity is unnecessary fully, and they instead wish to destroy fully their injection needle before processing.These users' example is diabetic and dentist, and these two kinds of people use very little very thin injection needle.Though these people wish their used injection needle of appropriate processing, yet too the high cost of complicated apparatus for destroying has stoped such dealing carefully with.

Summary of the present invention

At above problem, the invention provides a kind of portable device, can be used for many occasions, it can be self-powered, can a step destroy the injection needle of different length and bore, and can sterilize and/or prevent the escape of pathogen and potential pollutant.Moreover one embodiment of the present of invention provide a kind of simple and cheap injection needle apparatus for destroying, and this device can fully be destroyed rapidly as dentist or the used injection needle of diabetic.

In brief, the present invention is a kind of portable injection needle apparatus for destroying, it has been equipped with a power supply, as interchangeable or chargeable battery, one adjustable rotating disk in order to two slits between the electrode to be set, thereby allows this device to be used to the injection needle of different bores, with a filter that has soaked into disinfectant, from device, escape in order to prevent granular or airborne pathogen.Battery can be chargeable.Yet, battery does not directly link to each other with one of electrode, it can with an energy accumulating device as an inductor, capacitor or silicon controlled rectifier (SCR) coupling of circuits, energy accumulating device is by battery charge, and keeps electric charge to be inserted into and slit between two electrodes just discharges electric charge when producing short circuit until injection needle.D/d electric charge, or the intensity of electric arc is enough to destroy little injection needle fully, and the injection needle that does not need the user that length is diminished gradually inserts to guarantee the destruction of injection needle.Under the other situation, although to big injection needle, destruction and battery that the electric charge that discharges has been finished injection needle very apace also can continue toward electrode power supply, so that promptly finish the destruction fully of big injection needle after initial insertion and electric charge release.

This device by configuration one in order to the element of adjusting the slit between the electrode to admit the injection needle of different length and bore.This regulating element is controlled by a rotating disk, and the user rotates rotating disk with mobile adjustable electrode.The bias voltage that has reduced a spring along a direction rotation rotating disk moves apart second electrode to allow adjustable electrode, thereby more effectively admits bigger injection needle.When another direction is rotated rotating disk, increase the bias voltage of spring and force adjustable electrode and second electrode moves towards one another, thereby admit less injection needle.If be provided with such adjusting, the user is difficult to destroy fully all injection needles.If injection needle when excessive, is rocked before and after the user is forced to probably in the slit for little injection needle, to confirm contacting fully between injection needle and the electrode.Rocking like this may be inadequate, and may leave over down injection needle danger point " stub " (nub).In addition, if the slit is too small, electrode can be by quick-wearing very when being used for big injection needle, finally cause electrode failure or cause at least with other situation under compare and need earlier replace electrode.

In one embodiment, a power supply and a motorcoupling, motor selectively rotates second electrode, to remove the slag that produces in the process of destroying needles, substantially as the 5th, 138, No. 124 institutes of United States Patent (USP) that authorize people such as Kirk describe and description.Above-mentioned steps realizes fully in accordance with the reference.When power supply is battery, should use direct current " dc " motor.Because motor can be filled in device with injection needle the user, thereby electricity is the adjustable electrode and second electrode in succession, and cause storing when electric charge discharges and be actuated, so can use high start torque engine (as the dc engine), to begin to rotate second electrode immediately.Rotate immediately and guaranteed that " slag " or other residue that is produced by the destruction of injection needle have been thrown in the droppable box by the rotation of second electrode, and can be attached on the electrode and reduce the effectiveness of electrode.

In another embodiment, second electrode is one to have the flat board of at least one sloping edge.One moves or vibrating elements and this flat board are coupled, so as to move back and forth dull and stereotyped, thereby slag is flowed down from the side of flat board, clearing electrode effectively.Move with vibration and should not cause the big displacement of electrode, though electrode is vibrated with high-frequency, and make an edge of electrode tilt to have to help remove all slags basically.Such vibrating elements can be a buzzer circuit, and it utilizes coil to produce a magnetic field, and magnetic field pulls to coil with sheet metal.When the flat board of stopping from it when sheet metal moves apart, between coil and power supply thereof, produce and open circuit, cause sheet metal to get back to its stop place, and be powered at this dot circuit, sheet metal is pulled away from its stop position (the intensity that can be by changing the magnetic field that is produced by coil or the elastic property of sheet metal change the frequency of buzzer circuit) again.Link to each other with electrode by the end with sheet metal, electrode will move back and forth back and forth when sheet metal moves around.Another kind of moving meter is a motor only, and it is that rotate and weight axle is eccentric, thereby makes motor vibration.Motor and electrode mechanical couplings can be reached electrode with vibration.

Motor can be used to traveling electrode, simultaneously its axle also can with fan coupling, said fans is cigarette, dust or the air that contains particle suck and make it to contain battery by one, motor is in the module case of electrode and disposable box.By disposable box, disposable box utilizes washer sealing in a side of its module case to air by the passage guiding, and to prevent cigarette, dust and particle enter among the module case of motor.Air is through having soaked into the filter of disinfectant, and above-mentioned filter is installed on the removable dish, thereby allows to replace filter or upgrade disinfectant.Disinfectant clears the pollution off from air and makes the volatile matter deodorizing that is produced when residue gasifies on injection needle simultaneously.Timer on the control panel and motor coupling, guarantee motor with the running of set time interval, thereby fan is sucked in the box air of capacity to prevent any because steam that the destruction of injection needle produces and smog are escaped under the situation without filter sterilization that is full of disinfectant and pure and freshization.

In another embodiment, this device contains a module case that surrounds battery, battery can and energy storage circuit, first electrode and the coupling of second electrode, one of first or second electrode can be provided with the adjuster of regulating element, adjuster can allow the user to regulate slit between first electrode and second electrode, admits the injection needle of different size specification with the size dimension of regulating the slit.Energy accumulating device can contain capacitor, an inductor or a silicon controlled rectifier (SCR) circuit, and it can be coupled with battery, storage power, and be inserted into the electric charge that the abrupt release of two electrodes of Kong Bingyu contact of chest stores at injection needle.If injection needle is enough little, the common metal tip of destroying needles in fact immediately of the electric charge that discharges, thereby this embodiment is particularly useful when destroying the injection needle at " two tip ", " two tip " injection needle has one first injection needle part, and its tip is in the external extension of syringe; With one second injection needle part, this part extends in the body of syringe by pullover (hub).Usually, because the second portion of injection needle is held by syringe, the destruction of injection needle requires the two inconvenient steps to handle, the user sharp-pointed first of destroying needles at first then removes drift and destroys the second portion that extends into the injection needle in the syringe body therein.Yet, use energy accumulating device to allow this device to be inserted in the hole and produce enough powerful electric arc when contacting two electrodes or discharge with the total length of destroying needles (such as, first and second parts) at entry needle.

Can charging assembly be set and electric current uses jointly, can use LED to show whether battery needs charging or electric capacity when to be recharged and to be ready to use in and destroy another injection needle.

In brief, the invention provides a kind of device, in order to safety, destroy basically the skin of virtually any size fully effectively and go into injection needle and prevent steam when destroying used syringe needle, the distributing of dust, particle or air approach.Be provided with the device of removing slag from electrode, thus the maximum effect of having brought into play electrode.Of the present invention a kind of portable, cheap style can be used to destroy little injection needle fully, comprises two most advanced and sophisticated injection needles.

Correspondingly one of target of the present invention provides a kind of mancarried device that is used for destroying needles.

Another target of the present invention is that a power supply and an energy accumulating device are coupled, and energy accumulating device provides enough powerful discharge to destroy used injection needle at least in part.

A further target of the present invention provides a rotating disk that is coupled with the slit adjuster, electric current is sent to the size in the slit between the electrode of injection needle to be destroyed with appropriate adjustment.

Another target of the present invention provides a filter that has soaked into disinfectant, to clean up hill and dale at destroying needles steam and other pollutant to discharging.

Other target of the present invention, feature and advantage will be conspicuous with reference to the remainder of presents.

The description of figure

Fig. 1 has shown an embodiment of portable injection needle apparatus for destroying 10 of the present invention with the form of diagram component drawings, and a module case 11 is holding power supply, as the battery 12 that links to each other with the control panel 14 that comprises timer 15.One charging lead-out wire 16 can be set, can be inserted into charging device, to give battery 12 chargings so that install 10.Electric wire 18 is guided into electric charge or energy storage circuit 20 from control panel 14, be drawn towards motor 22 subsequently.Storage circuit 20 is made up of electric capacity usually, although also can use other device as inductor or silicon controlled rectifier (SCR), outside module case, also LED13 can be set, to show to the user whether battery 12 needs charging or storage circuit 20 whether to be recharged, whether has prepared to admit and destroy another injection needle thereby install 10.

Motor 22 drive motor axles 24, motor reel 24 rotate first belt pulley 26 and web wheel fan 32, and web wheel fan 32 has many battens 34.One O shape endless belt (O-ringbelt) is coupled first belt pulley 26 and second belt pulley 28, second belt pulley 28 is drive electrode axle 40 then, by plastic material, as the phenol muntenite, make first and

second belt pulley

26 and 28, and use an O shape endless belt 30 to guarantee, if install 10 by the user with the injection needle obstruction firmly,

belt pulley

26 and 28 will stop when the motor excess load.

At the tip of electrode stem 40 are rotating electrodes 44.Electric energy is transferred into electrode 44 by brush 44, and brush 44 links to each other the electrode axis of electric wire 18 with conduction.Although brush 42 can place a side of electrode axis 42 to guarantee better current delivery brush 42 near the tip of electrode axis 42.As substituting, brush 42 can directly link to each other with rotating electrode 44, and a groove separates the tip of brush 42 with rotating electrode, disturbs the current delivery of being finished by brush 42 with the residue that prevents injection needle.

In Fig. 2 A and Fig. 2 B, can observe adjustable electrode 46 best by separating by slit 52 with rotating electrode 44.One slit regulating element 54 allow users to rotate rotating disk 56 and regulate rotating electrode 44 and adjustable electrode 46 between slit 52.Adjustable electrode 46 by spring 60 biasings near fulcrum 62.The setting screw rod 64 of one band spring is used to set the initial size in slit 52.Rotating rotating disk 56 makes it move up or down along threaded screw rod 58; Thereby the tip 57 of rotating disk 56 is moved toward or moves apart adjustable electrode 46.Because the other end of 60 pairs of adjustable electrodes of spring upwards applies bias voltage, make most advanced and sophisticated 57 to move up or down so rotate rotating disk 56, cause adjustable electrode move near or away from rotating electrode 44.As substituting, if the geometry of module case 11 does not allow rotating disk 56 is directly placed on the adjustable electrode 46, can use the tip 57 and adjustable electrode 46 of one second strip material connection rotating disk 56, thereby the power that will produce by rotating rotating disk 56 converts the motion of adjustable electrode 46 to.

Adjustable electrode 46 has defined an inclined-plane 48, its end ends at most advanced and sophisticated 50, be used for concentrating electromotive force, in case and injection needle 71 inserted and contacted simultaneously with rotating electrode 44 by opening 68 with adjustable electrode 46 by module case 1, inclined-plane 48 is sent to the metal syringe needle tip with electric current.One guiding piece 74 is set.Guiding piece 74 can be made into infundibulate usually, and has spring, and spring is holding flexible portion, and flexible portion is further opened according to the size dimension of the injection needle 71 that is inserted into opening 68.Guiding piece 74 has guaranteed that the injection needle tip is directly caused slit 52 and ruins with marketing.Guiding piece 74 has been eliminated and " has been rocked " injection needle tip 71 back and forth to reach the most advanced and sophisticated needs that contact with electrode of injection needle, guiding piece 74 has also blocked the spark that produces for the user in the destruction process, and the refuse that has reduced to produce in destruction spills from opening 68, and splashes user's possibility on hand.

Injection needle most advanced and sophisticated 71 and electrode contacted closure in fact by two the open electric circuits that electrode form in parallel with storage circuit 20 and battery 12.The closure of this circuit causes storage circuit 20 to discharge immediately and produce electric arc destroying needles tip 71 between two electrode.About 6 volts voltage of having found battery promptly is enough to destroy most of injection needles 70, and this has strengthened by the effective current transmission of electrode to injection needle 70 when initial greatly owing to storage circuit 20 especially.

The electric current transmission is made the most advanced and sophisticated heating of injection needle and is molten into slag 72 to having high-resistance injection needle tip 71.The rotation of rotating electrode 44 is thrown to slag 72 in the box 80 downwards and further the injection needle tip " is drawn in " among the auto levelizer 10.Use is positioned at protects screen can further guarantee slag 72 around rotating electrode 44 and adjustable electrode 46 and imported among the box 80 and can not spill from opening 68 downwards within the module case 11.Although major part can be destroyed by electric current at remaining residue among the injection needle tip after the use, can produce some cigarettes, steam or dust.Guiding piece 74 and protect the great majority that screen may prevent these materials and escape to elect from opening 68; However, be provided with the running of fan 32, many these class materials will escape out.

Fan 32 sucks box 80 by opening 68 with air, has been full of the emanation that the destruction owing to injection needle tip 71 produces in the air, and has been directed to filter 82.Filter 82 has soaked into strong disinfectant, and any pathogen that may be present in injection needle most advanced and sophisticated 71 and do not destroyed of deactivation also makes with fresh airization simultaneously.Filter 82 can be made by multilayer film, to catch the particle of different sizes better.Filter 82 is held to be stayed in one movably in the dish, and dish can or be removed from module case 11 by plug-in package case 11 easily, thereby allows replenishing and the replacing of filter 82 disinfectant.As an alternative, can use door or slip passage opening to obtain arriving the path of the dish that will keep filter 82.After passing through filter 82, the air after the deodorizing is discharged module case 11 by exhaust outlet 84.Pad 82 prevents unfiltered gas by box 80, because allow unfiltered air to give an offensive smell from module case 11 by not only can causing, the particle that also can cause motor 22 to be found in the filtered air not stops up.

Fig. 3 has shown one embodiment of the present of invention, and this embodiment is provided with module case 100, is holding the regulating element 102 that another is used to regulate distance between travelling electrode 110 and the conductive plate 120.Module case 100 is also surrounded and is contained power supply, and it can be a battery 12 or a transformer that can link to each other with main power source by ordinary plug and heart yearn, also contains energy storage circuit 20 and motor 130.(alternative is that the filtration system of being made up of fan and filter cartridge (filterecl catridge) also can be placed within the module case 100).

The vibration of oscillating plate 120 or move has guaranteed that slag 72 can not pile up on oscillating plate 120.Oscillating plate 120 is used as the electrode with conduct current injection needle tip, and injection needle is inserted into to be destroyed by the hole 101 of chest 100.Vibration can realize by pot-motor 130 is assembled on the oscillating plate 120.By on motor reel the configuration eccentric weight 132 make engine luggine, and this vibration by mechanical transfer to oscillating plate 120.Vibration also can be by being attached at 120 of oscillating plates on the turning cylinder that is driven by motor 130 with a cam on the spring and the end adjacency of cam and plate 120 realized like this.The rotation of cam will be converted into the mechanical oscillation of propping up the oscillating plate 120 on spring.

As an alternative, oscillating plate can be defined within a passage or the track, and has an end to link to each other with vibrating elements.Vibrating elements makes oscillating plate 120, and back and forth movement is removing slag within track, otherwise slag can be attached on the oscillating plate 120.One of this vibrating elements can be a buzzer circuit, yet also can use other any elements that is used for mobile oscillating plate 120.Moreover, cleaning parts can be set clear up oscillating plate 120 to allow the user.The cleaning parts can be blades adjacent with track, can be close to track, are preferably the user and move, so that " wipe " slag and other residue that produces away after destroying one or more injection needles from oscillating plate 120.As alternative, the cleaning parts may simply be a block, and one surface both can have been moved along the surface of oscillating plate 120 artificially for the cleaning surface, also can be close to the surface of oscillating plate when oscillating plate 120 vibrates or be mobile.

Can use one to set screw rod 109 to set the initial slit between travelling electrode 110 and the oscillating plate 120, oscillating plate can be shaped as triangle, and leg-of-mutton one side is adjacent and thereon more attached with module case 100.Can narrowly do slit 102 to transfer wide or to transfer by operation regulating element 102, so that travelling electrode 110 is relocated onto the position (representing with PLg) that is suitable for destroying heavy caliber injection needle (its diameter is Dlg) from the position (representing with Psg) that is suitable for destroying small-bore injection needle (its diameter is Dsg).Regulating element 102 can rotate rotating disk 103 by the user and play a role with the size of selecting injection needle, may carry the back side that the rotation of the setting screw rod 105 of spring 104 forces the pointed end of setting screw rod 105 to abut against travelling electrode 110 and move.By setting the effect that screw rod 105 applied pressures have overcome biasing spring 106, travelling electrode 110 is rotated around pivoting point 108.

The initial position of movable electrode partly is decided by the size by the vertical movement vibration of plate 120 generations, can not contact with movable electrode 110 accidents when vibrating in order to guarantee plate 120, perhaps is necessary to make it only along its trunnion axis vibration.Can on oscillating plate 120 and movable electrode 110, tighten up a lead electric current is sent to electrode 10 and plate 120.Injection needle is inserted into the destruction that has caused the injection needle tip in the hole 101.The slag 72 that produces and other waste residue are shaken on the slave plate 120 by vibration and are fallen into box 80.Box 80 can be equipped with the filter 82 that disinfectant soaks into.

Fig. 4 has shown another embodiment, and this is simple, and portable device 140 is provided with battery 12, and the electric wire 18 of itself and the capacitor 142 and first and second electrodes 144,146 that lead links to each other.Notice that first and second electrodes 144,146 can be fixed, perhaps second electrode can be removed element 148 couplings with slag.Slag is removed element 148 may move second electrode 146 so that among slag drops into box 80 from second electrode by the running of motor.The running of motor 150 is to be controlled by the order of control panel 14.Yet remove element 148 fully for selecting for use for the present embodiment slag, because present embodiment is for very little entry needle 150 designs, depending merely on container 142 has been enough to destroy fully usually.

More than be only bright, explain and describe several embodiments of the present invention in order to show.For the personage of common skill, to the variation of these embodiment with to adjust will be conspicuous with this technology.These variations and adjustment be can carry out and scope of the present invention and essence spirit and claim subsequently do not departed from.
