Description

  The present invention relates to a package in which a cover of a medical device is housed by a box and a lid, and a cover mounting method for covering a predetermined reused medical device with the cover, and is particularly operable while maintaining a sterilized state. The present invention relates to a packaging body and a cover mounting method.

  When puncturing a hollow needle into a blood vessel, there are a case where a vein is punctured and a case where an artery is punctured depending on purposes such as blood collection or catheter insertion. When a blood vessel is punctured, blood is introduced into a puncture device such as a transparent syringe, and if it is a skilled person, it can be judged whether it is venous blood or arterial blood according to the color of the obtained blood, It can be difficult.

  Since blood oxygen saturation is low in veins and high in arteries, it is possible to determine whether the obtained blood is venous blood or arterial blood by measuring the oxygen saturation. In order to measure the oxygen saturation, for example, like the measuring instrument described in Patent Document 1, the light emitted from the light emitting element is transmitted through the blood to be measured and received by the light receiving element, and the wavelength band characteristic of the received light is measured. It can be determined whether it is venous blood or arterial blood. The use of a device based on such a principle is preferable because even an unskilled person can easily determine whether the obtained blood is venous blood or arterial blood.

  On the other hand, in a medical procedure, for example, when performing an operation, a person who comes into direct contact with a patient such as a surgeon basically touches only a sterilized medical device. For this reason, the medical device is stored in, for example, an individual bag and maintained in a sterilized state until use (see, for example, Patent Document 2). Such a medical device is basically a so-called disposable product that is discarded according to a predetermined procedure after the individual bag is opened and used.

  DESCRIPTION OF EMBODIMENTS Hereinafter, a packaging body and a cover mounting method according to the present invention will be described with reference to FIGS. The individual packaging body 120 (see FIG. 8) according to the present embodiment includes a sterilized state (including an aseptic state) of the cover body 12 among the blood type determination device 16 and the cover body 12 constituting the blood type determination device set 10. The same shall apply hereinafter). First, the blood type determination device set 10 will be described.

  As shown in FIGS. 1, 2, and 3, the blood type determination device set 10 is applied to a syringe set (puncture tool) 14, and includes a cover body 12 attached to the syringe set 14, A blood type determination unit 16 housed in the cover body 12;

  As shown in FIG. 4, the blood type determination unit 16 is substantially plate-shaped and has a tip direction (hereinafter also referred to as X1 direction. The opposite direction is also referred to as X2 direction, and the longitudinal direction is also referred to as X direction). A pair of bulging portions 18 and 20 projecting downward from the end portions are provided. A red measurement LED (light projecting unit) 22 and an infrared measurement LED (light projecting unit) 24 are provided on the inner side surface of the bulging part 18, and a light receiving element (light receiving unit) 26 is provided on the inner side surface of the bulging part 20. Is provided. The red measurement LED 22 and the infrared measurement LED 24 and the light receiving element 26 are provided at positions facing each other, and the light receiving element 26 can receive light emitted from the red measurement LED 22 and the infrared measurement LED 24. The red measurement LED 22 and the infrared measurement LED 24 are collectively referred to as a light projecting unit 27.

  A blue output LED (output unit, first lamp) 28 for venous blood detection display and a red output LED (output unit, second lamp) for arterial blood detection display are arranged in the X1 direction portion on the upper surface of the blood type determination unit 16. 30 and a green LED 32 as a power lamp. This peripheral portion has a gently inclined surface that goes downward in the X1 direction, and the visibility of the blue output LED 28, the red output LED 30, and the green LED 32 is improved. Since the venous blood is a relatively dark color, the venous blood detection display is set to the blue output LED 28, and the arterial blood is a relatively red color, so the arterial blood detection display is set to the red output LED 30, so that the operator is intuitive. The judgment result can be recognized. The letters “VEIN” are displayed near the blue output LED 28, “ALTERY” is displayed near the red output LED 30, and “POWER” is displayed near the green LED 32, making it easy to understand the function of each LED.

  On the upper surface of the blood type determination device 16, a battery cover 34 is provided in the X2 direction portion. The battery lid 34 can be removed by an operation such as turning with a screwdriver, and the internal battery 36 can be replaced. The battery 36 is, for example, a button battery.

  On the side surface of the blood type determination device 16, there are provided a groove 38 communicating with the upper and lower surfaces, and a momentary power switch 40 provided at the bottom of the groove 38. Since the power switch 40 is provided in the groove 38, it is not pressed carelessly. The power switch 40 also serves as a measurement start instruction means. When the power switch 40 is pressed, the blood type determination unit 16 starts measurement after a predetermined initial process. A control board 42 is provided inside the blood type determination unit 16.

  As shown in FIG. 5, the power switch 40 is provided between the battery 36 and the control board 42. When the power switch 40 is pressed, power is supplied to the power circuit 44 of the control board 42. Each function unit is energized via the power supply circuit 44 and the blood type determination unit 16 is activated.

  The control board 42 includes a microcomputer (determination unit) 50 that performs overall control of the blood type determination unit 16, an amplification circuit 52 that amplifies a signal received and output by the light receiving element 26, and a gain of the amplification circuit 52. It has a gain adjustment circuit 54 that performs adjustment, and a balance adjustment circuit 56 that balances signals. The signal amplified by the amplifier circuit 52 is supplied to the microcomputer 50. A plurality of amplifier circuits 52 may be provided. The gain adjustment circuit 54 and the balance adjustment circuit 56 are controlled by the microcomputer 50. The red measurement LED 22, the infrared measurement LED 24, the blue output LED 28, the red output LED 30 and the green LED 32 are turned on and off under the action of the microcomputer 50. For the red measurement LED 22 and the infrared measurement LED 24, a circuit for adjusting the light emission luminance may be provided.

  The microcomputer 50 has an MPU, a ROM, a RAM, and the like, and performs predetermined software processing by reading and executing a program recorded in the ROM.

  That is, the microcomputer 50 performs a predetermined initial confirmation when power is supplied, and turns on the green LED 32 if there is no abnormality. Next, the red measurement LED 22 and the infrared measurement LED 24 are turned on according to a predetermined procedure, and a signal received and output by the light receiving element 26 is read via the amplifier circuit 52. As will be described later, since blood to be measured flows between the light projecting unit 27 and the light receiving element 26, the light receiving element 26 receives light transmitted through the blood.

  By the way, oxyhemoglobin, which is often found in arterial blood, absorbs infrared light (that is, light from the infrared measurement LED 24, for example, light having a wavelength of 880 nm) more strongly than red light (that is, light from the red measurement LED 22, for example, light having a wavelength of 657 nm). Reduced hemoglobin, which is common in venous blood, has the property of absorbing red light more strongly than infrared light. Therefore, discrimination between venous blood and arterial blood can be made based on the signal obtained from the light receiving element 26. The microcomputer 50 performs such determination processing. When the venous blood is determined, the blue output LED 28 is turned on and the red output LED 30 is turned off. When the arterial blood is determined, the red output LED 30 is turned on and the blue output LED 30 is turned on. The output LED 28 is turned off.

  During a predetermined short period after the power is turned on, the blue output LED 28, the red output LED 30 and the green LED 32 may all be turned on so that it can be confirmed that there is no voltage drop or disconnection of the battery 36.

  When the voltage of the battery 36 has fallen, it is good to show a warning of voltage drop by blinking the green LED 32.

  While the determination process is being performed after the power is turned on, the blue output LED 28 and the red output LED 30 may be turned on, and when the determination process is completed, either one may be turned off based on the determination result. . In this case, the green LED 32 may be omitted.

  During the determination process, the blue output LED 28 and the red output LED 30 may blink to indicate that the determination process is being executed.

  If it is not possible to determine whether the blood is arterial blood or venous blood, both the blue output LED 28 and the red output LED 30 may be turned on to indicate a measurement error.

  The blood type determination device 16 configured in this way is basically used by being housed in the cover body 12.

  Returning to FIGS. 1 to 3, the cover body 12 includes a main body (first cover member) 60 on which the blood type determination device 16 is placed, and a lid having a long side connected to the main body 60 by a hinge 62. And a body (second cover member) 64, which can be folded by a hinge 62. The cover body 12 is made of a resin material (for example, polyolefin).

  The main body 60 has a box shape in which the upper surface is opened and the blood type determination device 16 is placed. The main body 60 has a bulging portion (measuring portion) 66 protruding downward at the end in the X1 direction. It is L-shaped when viewed (see FIG. 3).

  The bulging portion 66 includes concave portions 68 and 70 into which the bulging portions 18 and 20 are inserted, and a partition portion (blood passage portion) 72 provided between the concave portions 68 and 70.

  As shown in FIG. 6, the partition 72 includes a male luer-shaped distal end connecting portion 74 projecting in the X1 direction, a female luer-shaped proximal end connecting portion 76 projecting in the X2 direction, and these distal end connecting portions. 74 and a blood inflow portion 78 communicating the proximal end connection portion 76 in the X direction.

  As shown in FIGS. 6 and 7, a substantially square measurement chamber 80 is provided in the middle of the blood inflow portion 78 in front view, and transparent on the left and right wall surfaces (mounting portions) of the measurement chamber 80. Measurement windows 82 and 84 are formed.

  The measurement windows 82 and 84 only need to be able to be measured by the light receiving element 26 through the blood filled in the measurement chamber 80 with the light of the light projecting unit 27, and are not necessarily transparent, and are colored or translucent. However, it is only necessary to be thin enough to transmit light.

  Although the light projecting unit 27 and the light receiving element 26 are disposed in the vicinity of the measurement windows 82 and 84, the light emitted from the light emitter at a location separated by the light guide may be guided to the measurement windows 82 and 84. A light guide may be used for the blue output LED 28, the red output LED 30, and the green LED 32.

  When the main body 60 is colored, the measurement windows 82 and 84 may be made of the same material to be appropriately thin, or may be made of different transparent materials. When the main body 60 is transparent, the portions other than the measurement windows 82 and 84 may be colored so as to be shielded from light. The coloring in this case may not be the whole main body 60, for example, the bulging part 66 other than the measurement windows 82 and 84 may be colored. In order to obtain a high light-shielding property, the color of the portions other than the measurement windows 82 and 84 is preferably black. By shielding light at least around the measurement windows 82 and 84, the influence of disturbance light on the light projecting unit 27 and the light receiving element 26 is reduced, and stable determination is possible.

  The bulging portion 18 and the bulging portion 20 sandwich the partition 72, there is no gap between the light projecting portion 27 and the measurement window 82, and between the light receiving element 26 and the measurement window 84, and the measurement window. Reference numerals 82 and 84 denote plane plates parallel to each other, which are suitable for optical measurement with little useless reflection and refraction of light. Further, the bulging portion 18 and the bulging portion 20 press and hold the partition portion 72 with an appropriate force, and the blood type determination device 16 is stabilized.

  Returning to FIG. 1, a protrusion (switch action portion) 86 extending in the vertical direction is provided on the inner side surface of the main body 60. The protrusion 86 is shaped to push the power switch 40 at a position that fits into the groove 38 when the blood type determination device 16 is mounted on the main body 60. The protrusion 86 is inclined at the upper end so as to be easily fitted into the groove 38.

  The lid 64 is fixed by engaging the engaging portion 88 of the lid 64 and the engaged portion 90 of the main body 60 by bending the hinge 62 (see FIG. 2). As a result, the main body 60 and the lid body 64 are combined with each other to cover the blood type determination unit 16 so that no manual contact is made. Thus, the blood type determination device 16 can be covered only by folding the lid 64, and the operation is simple.

  A skirt portion 89 that covers the corresponding side of the upper end of the main body 60 is provided on three sides other than the side where the hinge 62 is provided around the lid body 64.

  Below the main body 60, there is provided a syringe holding member 91 having an arcuate cylindrical shape that is bilaterally symmetric and that opens downward. The syringe holding member 91 has moderate elasticity and can stably hold the outer cylinder 106 of the syringe 100 described later (see FIG. 2). The syringe holding member 91 may be transparent or provided with a viewing window so that blood introduced into the syringe 100 can be easily visually recognized.

  As shown in FIG. 2, the lid 64 is provided with holes (output windows) 92, 94, and 96 that allow the blue output LED 28, the red output LED 30, and the green LED 32 to be visually recognized on the upper surface of the blood type determination unit 16. An annular protrusion 98 is provided around each of the holes 92, 94 and 96, and the blue output LED 28, the red output LED 30 and the green LED 32 are not manually contacted. The means for visually recognizing the blue output LED 28, the red output LED 30, and the green LED 32 is not limited to a hole, and any means that can transmit light may be used, such as a transparent window or a thin portion.

  “VEIN” is displayed near the hole 92, “ALTERY” is displayed near the hole 94, and “POWER” is displayed near the hole 96, making it easy to understand the function of the LED visible from each hole. It is.

  The syringe set (puncture tool) 14 is a general-purpose product and includes a syringe 100 and a needle body 102. The syringe 100 includes a transparent outer cylinder 106, a plunger 107 with a gasket that is slidably provided in the outer cylinder 106, and a male-luer reduced diameter portion 108 at the tip of the outer cylinder 106. The needle body 102 includes a hollow needle 110 at the tip and a hub 112 that holds the needle 110. The hub 112 has a female luer taper shape, and is normally used by being attached to the reduced diameter portion 108 of the syringe 100. The syringe 100 and the needle body 102 are disposable products that have been sterilized in advance.

  When the blood type determination device set 10 is applied to the syringe set 14, as shown in FIGS. 3 and 6, the reduced diameter portion 108 of the syringe 100 is connected to the proximal end connection portion 76, and the hub 112 is connected. Connect to the tip connection portion 74. Thereby, the blood inflow part 78 of the partition part 72 is installed between the syringe 100 and the needle body 102, and the blood collected by the needle body 102 flows in.

  Next, the individual package 120 according to the present embodiment will be described. The individual packaging body 120 packages the cover body 12 in a sterilized state.

The activation of the blood type determination unit 16 can be confirmed by turning on the green LED 32 of the power lamp.

  As shown in the order of FIGS. 13 and 14, the second operator bends the individual package 120 together with the cover body 12 at the bent portion 136 and the hinge 62. Thereby, the engaging part 88 and the engaged part 90 are engaged, and the cover body 12 is fixed in a state where the blood type determination device 16 is accommodated.

  As shown in FIG. 15, when the second operator bends the box 122 of the individual package 120, the second operator touches the individual package 120 and does not touch at least the outer surface 300 of the cover body 12. The outer surface 300 is maintained in a sterilized state. Moreover, the blood type determination device 16 is in contact with the inner surface 302 of the lid body 64, and the outer surface 304 of the lid body 64 is maintained in a sterilized state.

  Next, the first operator picks up the blood type determiner set 10 in which the cover body 12 and the blood type determiner 16 are combined from the individual package 120, and sterilizes the blood type determiner set 10 as shown in FIG. The syringe 100 and the needle body 102 thus mounted are attached.

  Further, as shown in FIG. 16, the first operator punctures a predetermined vein or artery of the patient with the needle 110 of the needle body 102 according to the purpose, and pulls the plunger 107. By puncturing and operation of the plunger 107, blood flows into the blood inflow portion 78 (see FIG. 7) via the needle 110 and the hub 112, fills, and further flows into the syringe 100. At this time, the internal blood type determination unit 16 has already been activated, and the light emitted by the red measurement LED 22 and the infrared measurement LED 24 in a predetermined pattern passes through the measurement window 82, the blood in the blood inflow portion 78, and the measurement window 84. And reaches the light receiving element 26.

  The signal received by the light receiving element 26 is supplied to the microcomputer 50 for signal processing, and it is determined whether the blood in the blood inflow portion 78 is venous blood or arterial blood. When it is venous blood, the blue output LED 28 is lit to indicate arterial blood. Sometimes the red output LED 30 is lit. Thereby, the first operator can easily determine whether the blood obtained in the syringe 100 is venous blood or arterial blood. As is clear from FIG. 16, the blue output LED 28, the red output LED 30, and the green LED 32 are provided on the X1 direction side of the upper surface of the cover body 12, so that visibility is good.

  Based on the determination result, if the place where the vein is punctured is punctured into the artery or vice versa, after performing treatment such as hemostasis as necessary, once the needle 110 is removed and the puncture is performed again Good.

  After a predetermined procedure, the first operator removes the needle 110 from the patient. The first operator or the second operator removes the syringe 100 and the needle body 102 from the blood type determination device set 10. Further, the second operator opens the cover body 12 of the blood type determiner set 10 and takes out the blood type determiner 16 accommodated therein. The cover body 12, the syringe 100, and the needle body 102 are disposable items, and are discarded according to a predetermined procedure.

  In such a series of operations, the outer surfaces 300 and 304 of the cover body 12 are maintained in a sterilized state, and the first operator touches only the surface in which the sterilized state is maintained.

  According to the blood type determination device set 10 and the cover body 12, the blood inflow portion 78 can be configured to have a moderately small diameter, and blood can be quickly filled, so that early blood type determination is possible. Moreover, since the wall surfaces of the partition part (mounting part) 72 and the blood inflow part 78 are flat, the light irradiated from the light projecting part 27 can be received by the light receiving element 26 without being irregularly reflected. The cover body 12 can be applied to a general-purpose syringe 100 and a needle body 102.

  The output form is not limited to the lamps such as the blue output LED 28 and the red output LED 30. For example, a liquid crystal display, a wireless output, or an output by a sounding body (sound or sound) may be used instead of the lamp. A lamp may be used in combination.

  In the output by the sound generator, the judgment result can be easily recognized by generating different sounds depending on whether the judgment result is venous blood or arterial blood. Here, different sounds are broadly defined as long as they can be distinguished, and include cases where timbre, volume, frequency, pronunciation pattern, sound, and the like are different. Further, the holes 92 and 94 (see FIG. 2) can be omitted in the wireless output and the sound output. The power supply can be turned on and off by radio output and sound output, and the green LED 32 and the hole 96 can be omitted.

  As described above, in the individual wrapping bodies 120 and 121 according to the present embodiment, the cover body 12 is housed in the box body 122 with the hinge 62 disposed in the adjacent portion (wall portion 130). After the film 124 is removed from the box body 122, the cover body 12 and the box body 122 can be folded at the adjacent portion and the hinge 62 at the same time. At this time, since the second operator only needs to touch the outer surface of the box body 122, at least the outer surface of the cover body 12 can be maintained in a sterilized state.

  When the flange 132 is provided, the film 124 can be easily attached. Further, by providing the bent portion 136, the bent portion 136 can be formed together with the adjacent portion, and the wall portion 130 of the box body 122 and the hinge 62 of the cover body 12 can be appropriately bent simultaneously.

  The blood type determination device 16 is covered with a cover body 12 so as not to be touched manually, and the puncture device is projected and received through a predetermined measurement window, whereby blood collected by the puncture device is venous blood. Or arterial blood can be easily determined. The cover body 12 has a simple structure, can be made into a disposable product sterilized in advance, and can operate the blood type determination device set 10 in a sterilized state. The blood type determination device 16 does not require disinfection or special sterilization treatment, and can be used as a so-called reuse product.

  The cover body 12 is not limited to opening and closing by the hinge 62, but may be any structure that covers the blood type determination unit 16 so that the parts corresponding to the main body 60 and the lid body 64 are combined with each other so as not to be touched manually. For example, a slide type or a shutter type may be used. The members covering the blood type determination device 16 are not limited to the two members of the main body 60 and the lid body 64, and for example, the lid body 64 portion may be divided into two and made into a double door type.

  Further, the puncture device is not limited to the one composed of the needle body 102 and the syringe 100, but is a puncture device used for introducing a guide wire into a blood vessel (for example, as described in JP-A-2007-209). In addition, a needle body and a syringe are connected via a connector having a branch pipe with a valve body), or a double needle (indwelling needle) consisting of an inner needle and a catheter is used instead of the needle body. May be.

  The medical device stored in the cover body 12 is not limited to the blood type determination device 16 and can be applied to various medical devices used in an operating room, an intensive care unit, and the like.

  Further, in the cover mounting method according to the present embodiment, the cover body 12 and the box body 122 are bent simultaneously using the individual wrapping bodies 120 and 121, and the second operator only touches the outer surface of the box body 122. All you need is an operation.
