Description
Technical Field
The invention relates to the technical field of hospital automatic drug management systems, in particular to a drug box sensor of a drug management system and a drug box.
Background
With the advancement of technology, automated drug management systems are widely used in hospitals, for example, a prior application with application number CN201110211704 filed before the present company, such an automatic drug access system is proposed. Conventional drug accessing systems generally include a central control unit and an input/output device, for example, many drug management systems use a computer to perform drug management. The drug management system has a number of drug storage spaces, such as drawers, drug cabinets, or controllable drug cassettes, which typically have locking mechanisms that can be controlled by electrical signals, and a power supply that supplies power to the central control unit, input and output devices, and locks. In the field of drug administration, a manager generally needs to detect whether a drug is put in a drug box or whether the drug in the drug box is taken out, and therefore, the manager sets a sensor in the drug box to sense the existence of the drug. For example, prior applications with application numbers CN201210054026 and CN201210053997, filed previously by the present company, respectively disclose a medicine cartridge using an optical sensor, and prior application with application number CN201210054023 discloses a medicine bottle accessing unit using a piezoelectric or photoelectric sensor. In the prior art, the medicine bottle detection unit in the medicine box generally adopts a piezoelectric sensor or a photoelectric sensor, because the volume of the piezoelectric sensor and the photoelectric sensor is small, the sensor unit of the medicine box does not occupy space, and the medicine box can leave more space for storing the medicine bottle. However, the piezoelectric sensor and the photoelectric sensor that directly sense whether a medicine is put into the medicine box have their own disadvantages, for example, in order to achieve detection accuracy, the piezoelectric sensor is generally disposed on the upper surface of the bottom plate of the medicine box, so that after a medicine bottle is put into the medicine box, the medicine bottle is directly pressed on the piezoelectric sensor, the piezoelectric sensor sends an electric signal with a changed state to the control unit, the control unit judges that the medicine bottle is put into the medicine box according to the electric signal, the photoelectric sensor is also the same, the photoelectric sensor is generally disposed on the upper surface or the side wall of the bottom plate of the medicine box, and after the medicine bottle is put into the medicine box, light emitted by the photoelectric sensor is shielded by the medicine bottle, so that an electric signal with a changed state is sent to the control unit. However, the piezoelectric sensor or the photoelectric sensor is arranged in the medicine box, so that hidden danger exists, firstly, a sensor arranged on the inner surface of the medicine box is required to be provided with a small hole for leading out a signal line or a power line in order to transmit an electric signal to a control unit outside the medicine box, when the medicine bottle is damaged or toppled over, medicine in the medicine bottle is easy to damage the sensor unit on the inner surface of the medicine box, and liquid medicine can flow out through the small hole and drip on a circuit board at the lower part of the medicine box to corrode the control circuit, so that the whole medicine box is scrapped; secondly, the photoelectric sensor needs to emit detection light, the sensitivity to the transparent glass medicine bottle is poor, and part of the medicine must be kept away from light, and the influence of the detection light (including visible light and invisible light) emitted by the photoelectric sensor on the medicine in the medicine container is unknown, which easily causes the failure of the medicine.
In the 90's last century, some U.S. researchers discovered that low levels of electromagnetic fields exist in residential dwellings that at least diminish or eliminate the effects of a widely used drug in vitro, for example, researchers discovered that in the laboratory, when an anti-cancer drug tamoxifen was exposed to such fields, it lost its ability to stop the proliferation of cancer cells, and the results of these studies reported by the U.S. public health agency at the washington-held conference increased the concern that electromagnetic waves emitted by the detection circuitry of conventional cartridge sensors may also adversely affect the efficacy, shelf life of certain drugs. However, in the field of cartridge sensor technology, technicians always have the optical or magnetic signal of the sensor directly act on the drug or the drug package, or expose the drug to the magnetic field generated by the measuring circuit, and do not recognize the need to avoid the influence of electromagnetic waves and light on the drug.

Detailed Description
The technical solution of the present invention is further described below with reference to specific examples.
As shown in fig. 1, in a first embodiment, the medicine box of the present invention has a storage area 1, the storage area 1 has a side wall, the side wall has a displacement unit 3, the upper part of the displacement unit 3 is smaller than the lower part, and preferably, the longitudinal section of the displacement unit 3 is in the shape of an isosceles triangle. The cartridge side wall has a passage (not shown) through which the displacement unit 3 passes, and the upper part of the displacement unit 3 is fixed to the shaft 2 at the inner upper surface of the passage and can rotate around the shaft 2 to a certain extent. As can be seen from fig. 1, when the vial 5 is not inserted in the cartridge, the displacement unit 3 is in equilibrium under the effect of gravity and is in a first position in which the displacement unit 3 passes through the passage, partly inside the cartridge and partly outside the cartridge. It will be readily appreciated that in the first position the displacement unit 3 is located in equal volumes in the interior and in the exterior of the cartridge. A sensing unit, preferably a piezoelectric sensor 4 in this embodiment, is disposed outside the medicine box storage area 1, as shown in fig. 1, the piezoelectric sensor 4 is disposed in a device area separated from the medicine box storage area 1 and fixed at a position opposite to the left edge of the displacement unit 3, a base of the piezoelectric sensor 4 is fixed on an inner side wall of the device area, when a medicine bottle is not put into the medicine box, the piezoelectric sensor 4 has a certain gap with the displacement unit 3, and the piezoelectric sensor 4 does not sense any pressure value.
As shown in fig. 2, when a medicine bottle 5 is placed in the medicine box storage area 1, the medicine bottle body contacts the right edge of the displacement unit 3, the displacement unit 3 rotates around the shaft 2 under the gravity of the medicine bottle, so that a part of the displacement unit 3 moves from the inside of the medicine box storage area 1 to the outside of the medicine box storage area 1 through the channel to make the displacement unit 3 in the second position, in which the left edge of the displacement unit 3 contacts the piezoelectric sensor 4, and the piezoelectric sensor 4 senses the pressure from the displacement unit 3 and outputs the first displacement signal. It should be noted that, when the displacement unit 3 is at the first position, the rightmost edge thereof needs to be located at a position deep enough in the storage space inside the medicine box to ensure that the medicine bottle 5 can sufficiently contact the medicine bottle body after being placed in the medicine box storage area 1, and the displacement unit 3 can generate a sufficient displacement amount.
When the medicine bottle 5 is taken out from the medicine box, the medicine bottle body is removed from the medicine box storage area 1, the displacement unit 3 rotates around the shaft 2 under the self gravity, the second position returns to the first position, the left edge of the displacement unit 3 is not in contact with the piezoelectric sensor 4, the piezoelectric sensor 4 does not sense the pressure from the displacement unit 3, and the second displacement signal is output.
Further, the medicine box sensor further has a judging unit (not shown) which receives the first and second displacement signals and judges whether the medicine bottle is put into or taken out of the medicine box based on the first and second displacement signals. If the medicine box receives the first displacement signal, the judging unit judges that the medicine bottle is put into the medicine box, and if the medicine box receives the second displacement signal, the judging unit judges that the medicine bottle is taken out of the medicine box.
Further, the judgment unit judges the occupation state of the medicine box according to the first displacement signal and the second displacement signal. If the medicine box receives the first displacement signal, the judging unit judges that the medicine box is in an occupied state, and if the medicine box receives the second displacement signal, the judging unit judges that the medicine box is in an idle state.
In a second embodiment, as shown in fig. 3, the side wall of the cartridge of the present invention has a displacement unit 3, the displacement unit 3 having a longitudinal cross section that is left-right asymmetric, specifically, the portions of the displacement unit 3 inside and outside the cartridge storage area have different shapes, wherein the portion of the displacement unit 3 inside the cartridge protrudes from the inner surface of the side wall of the storage area and penetrates into the cartridge storage area 1. The cartridge side wall has a passage (not shown) through which the displacement unit passes, and as can be seen from fig. 3, the left end of the displacement unit 3 is connected with an elastic unit, preferably a spring 6, the right end of the spring 6 is connected with the displacement unit 3 and provides a supporting force, the left side of the spring 6 is connected with the pressure sensitive element of the piezoelectric sensor 4, and the substrate of the piezoelectric sensor 4 is fixed on the inner side wall of the device area. When a vial is not placed in the cartridge, the displacement unit 3 is in equilibrium under the action of the spring 6 and is in a first position in which the displacement unit 3 passes through the passage such that a portion of the volume is located in the cartridge storage area. Therefore, when the medicine bottle is not put in the medicine box, the displacement unit 3 does not apply pressure to the piezoelectric sensor 4 through the spring 6, and the piezoelectric sensor 4 does not sense any pressure value or only senses a small pressure value.
As shown in fig. 4, when the medicine bottle 5 is put into the medicine box, the medicine bottle body contacts the right edge of the displacement unit 3, the displacement unit 3 moves to the left under the pressure of the medicine bottle, so that a part of the displacement unit 3 moves from the medicine box storage area to the outside of the medicine box storage area or into the channel through the channel, so that the displacement unit 3 is in the second position, in which the spring 6 is pressed by the leftward movement of the displacement unit 3 as a whole, and the piezoelectric sensor 4 senses that the pressure from the displacement unit 3 is obviously increased and outputs the first displacement signal.
When the vial 5 is taken out of the cartridge, the vial body is removed from the cartridge, the displacement unit 3 returns from the second position to the first position under the action of the spring 6, the piezoelectric sensor 4 senses no pressure value or only a small pressure value and outputs a second displacement signal.
Further, the medicine box sensor further comprises a judging unit, the judging unit receives the first and second displacement signals, and judges whether the medicine bottle is put into or taken out of the medicine box and the occupation state of the medicine box according to the first displacement signal and the second displacement signal, and the judging method is the same as the first embodiment.
Preferably, the part of the displacement unit 3 inside the cartridge has a smooth surface, in particular at least the part in contact with the vial, for example a section curve which may be a part of a circle, ellipse, parabola, spiral. This has the added benefit of reducing drag when the vial 5 is placed in the drug storage area 1.
The additional advantageous effect of arranging the displacement unit 3 on the side wall of the drug cassette further includes the possibility of arranging the sensing unit also outside the side wall of the drug cassette, so that the liquid and powder medicine after the drug is broken will not corrode the circuit and cause malfunction of the sensing unit.
In a third embodiment, see fig. 5, the bottom plate of the cartridge has a passage (not shown) through which the displacement unit 3 can pass, and the cartridge comprises a storage area and a device area, which is separated from the storage area and which is arranged below the bottom plate of the cartridge storage area. In the present embodiment, the displacement unit 3 may be a cube, a rectangular parallelepiped, a terrace, a circular table, a cylinder, or the like, or may be a part or a combination of the above shapes. Taking a cuboid as an example, as shown in the left part of the medicine box in fig. 5, the upper surface of the displacement unit 3 is obviously higher than the bottom plate of the medicine box storage area, the lower surface of the displacement unit 3 is connected with a spring 6, the upper end of the spring 6 is connected with the lower surface of the displacement unit 3, the lower end of the spring 6 is fixed on the upper surface of the bottom plate of the equipment area, and at least one part of the displacement unit 3 can move between the storage area and the equipment area through the up-and-down movement of the displacement unit 3 in the channel. The opposite side walls of the equipment area are provided with a light emitter 7 and a light receiver 8, respectively.
As shown in the right part of the medicine box of fig. 5, which is arranged in a mirror image with the left part, when the medicine bottle 5 is placed in the medicine box storage area, the displacement unit 3 moves downwards from the first position through the channel to the second position and compresses the spring 6 under the action of the gravity of the medicine bottle 5, a part of the displacement unit 3 moves from the storage area to the equipment area and blocks the light emitted by the light emitter 5, so that the receiver 6 no longer receives the light emitted by the light emitter 5, and the receiver 6 sends a first displacement signal. It will be readily appreciated that the displacement of the displacement unit 3 requires a sufficient stroke so that it can reliably block the light of the light emitter 5.
When the medicine bottle is taken out from the medicine box storage area, the displacement unit 3 moves upwards under the action of the restoring force of the spring 6 and returns to the first position from the second position, at least a part of the volume of the displacement unit 3 passes through the channel and returns to the medicine box storage space without blocking light emitted by the light emitter 5, the receiver 6 receives the light emitted by the light emitter 5, and the receiver 6 sends a second displacement signal.
Further, the medicine box sensor further comprises a judging unit which receives the first and second displacement signals and judges whether the medicine bottle is put into or taken out of the medicine box and the occupation state of the medicine box according to the first displacement signal and the second displacement signal, and the judging method is the same as the first embodiment.
In a fourth embodiment, as shown in fig. 6, the medicine cassette has a storage area and a device area, the storage area and the device area being separated by a side wall panel of the medicine cassette storage area. The side wall 12 of the cartridge has a channel (not shown) through which the displacement unit 3 can pass, said channel being inclined, the opening of the channel in the equipment area being higher than the opening in the storage area. The displacement unit 3 passes through the channel, and a part of the displacement unit is located in the equipment area and a part of the displacement unit is located in the storage area. When a vial is not placed in the cartridge storage area, see the left part of fig. 6, the displacement unit 3 is in the first position under its own weight, it being understood that in the first position the mass of the part of the displacement unit 3 in the storage area is significantly greater than the mass of the part in the equipment area, said part of the displacement unit 3 in the equipment area having a first stop 9, the function of which first stop 9 is to prevent the displacement unit 3 from sliding completely into the storage area along the inclined channel under the influence of gravity. The first stopper 9 has a vertical left side surface on which a magnetic sheet 13 is provided. A hall sensor 11 for sensing a magnetic field generated by the magnetic sheet 13 is fixed at a position of the side wall of the equipment area opposite to the magnetic sheet. The displacement unit 3 has a second stop 10 in the part of the storage area, the right side of the second stop 10 having a surface for contact with the vial, preferably the smooth surface mentioned in the second embodiment. The second stop 10 serves to prevent the displacement member 1 from being pushed completely into the device area after the vial has been placed in the storage area.
As shown in the right portion of fig. 6, which is a mirror image of the left portion, when the medicine bottle is placed into the storage area from the side opening, the second stopper 10 of the displacement unit 3 contacts with the medicine bottle, the displacement unit 3 is entirely slidably displaced along the channel from the first position to the second position, so that at least a portion of the displacement unit 3 moves from the storage area to the equipment area through the channel, and at the same time, in the second position, the gap between the magnetic sheet 13 and the hall sensor 11 is reduced, the magnetic field intensity sensed by the hall sensor 11 is significantly increased, and thus the hall sensor 11 sends the first displacement signal.
When the medicine bottle is taken away by the storage area, the displacement unit 3 slides to the first position through the inclined channel under the action of self gravity, at the first position, the gap between the magnetic sheet 13 and the Hall sensor 11 is increased, the magnetic field intensity sensed by the Hall sensor 11 is obviously reduced, and therefore the Hall sensor 11 sends a second displacement signal.
Further, the medicine box sensor further comprises a judging unit, the judging unit receives the first and second displacement signals, and judges whether the medicine bottle is put into or taken out of the medicine box and the occupation state of the medicine box according to the first displacement signal and the second displacement signal, and the judging method is the same as the first embodiment.
Further, the side wall and the bottom plate of the medicine box are provided with magnetic shielding layers, the magnetic shielding layers can further eliminate the magnetic field influence of the magnet in the equipment area on the medicine in the storage area, for example, the magnetic shielding layers can be arranged on the upper surface and/or the lower surface of the partition plate, and can also be arranged in an interlayer between the side wall and the bottom plate of the medicine box. In a further preferable scheme, the magnetic shielding layer is made of a material with high magnetic permeability, such as permalloy, iron-aluminum alloy, silicon steel sheet, and the like. In one embodiment, the side walls and bottom panel themselves are made of a material having magnetic shielding capabilities. It should be noted that not all medicine boxes need to be provided with a magnetic shielding layer, and in the medicine box for storing medicines or consumables which have no influence on the magnetic field, the magnetic shielding layer can be cancelled, for example, the medicine box for storing Chinese patent medicines.
In the above embodiment, the determining unit may be a host of a drug management system, and management software of the host determines whether a drug is taken out of the drug cassette according to the first displacement signal and the second displacement signal; in other embodiments, the determination unit may be a processing unit composed of a single chip microcomputer and an MCU.
In the above embodiments, the medicine in the medicine cartridge of the present invention may be understood as a tablet medicine or a container containing a tablet, a powder, a liquid medicine, and a medical consumable.
In the second and third embodiments described above, the elastic body is a spring, and in alternative embodiments, the elastic element is a metal dome, an elastic rubber body, or a polyurethane-based plastic body.
In the above embodiments, the selection of the sensing units may be interchanged, or may be at least one of other types of piezoelectric sensing units, photoelectric sensing units, electromagnetic sensing units, switching units, and capacitance sensors, which at least implement sensing the displacement of the displacement unit between the first position and the second position and send displacement signals in at least two states, for example, when the sensing unit adopts a switching unit, the switching unit is set to be turned off when the displacement unit is in the first position, and the switching unit is set to be turned on when the displacement unit is in the second position, or vice versa.
In other alternative embodiments, the design of the moving unit is modified to convert the movement of the medicine into or out of the medicine box into the movement of the displacement unit between the first position and the second position and to transmit the movement to the outside of the medicine box, so as to ensure that no circuit, lead or sensing element exists in the storage space of the medicine box, thus avoiding the possibility of the medicine contacting with light and electromagnetic field and avoiding the influence of the factors on the medicine itself.
It will be appreciated by those skilled in the art that the drug sensor of the present invention may be used in drug storage units other than drug cassettes, such as drug cabinets. In addition, the medicine box can be used for storing bottled medicines, tablets, medicines with paper outer packages and other medical consumables.
The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can conceive of changes or substitutions within the technical scope of the present invention.
