Description

Background Art [0002] Blood transfusion safety mechanisms to prevent accidents [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood transfusion apparatus for injecting blood of a healthy person into a blood vessel of a patient and more particularly to a blood transfusion apparatus for blood transfusion, The present invention relates to a safety blood transfusion apparatus for preventing a transfusion accident that can be prevented.

The most common accident during transfusion is acute hemolytic transfusion. This is a reaction that occurs when the patient and the transfused blood do not match with each other. This is a fever in the early stage, which causes fever, rapid pulse, and worse blood pressure. Most of these cases are mistakenly made by medical personnel in identifying blood that matches the transfusion recipient. In other words, unlike ordinary syringes, which differ in color and packaging according to needle thickness, blood transfusion uses a blood transfusion apparatus (blood transfusion set) having the same shape and color regardless of blood type.

In recent years, oral syringes have been developed to reduce medication-related medical accidents. For example, filter syringes for filtering microscopic pieces of glass in ampules have also been used in child wards, and they have been shown to be at risk using visual effects that display high-risk drugs in red. Compared with various syringes and injection sets, current blood transfusion sets do not differentiate according to blood type or blood products, so it is difficult to prepare blood transfusions for blood transfusions by medical personnel. It is difficult to find the accident early. In addition, blood donors are not easy to visually confirm blood products such as blood type of their own, so that information on blood transfusion of patients is inevitably limited. Furthermore, as mentioned earlier, blood transfusion accidents are more serious than other medical accidents. Therefore, there is an urgent need for measures to prevent such blood transfusion accidents.

For example, Korean Patent Laid-Open Publication No. 2002-0009311, entitled "Blood bag safety device for preventing blood transfusion accident ", discloses a blood bag safety device including a locking device responsive to electromagnetic force, And reading out the bar code information attached to the bar code reader, and generating a response signal. In other words, blood transfusion, in which blood is changed through a blood bag having a stabilizing device, is essentially blocked by using digital information and a locking device, thereby minimizing the damage of human life.

However, embedding a stabilizer in a blood bag is impractical in terms of cost. In particular, since blood bags are required to store blood for a long period of time, there is a serious problem that the locking device is broken or broken due to exposure to a low temperature or a cryogenic temperature.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a blood transfusion apparatus for injecting blood of a healthy person into a blood vessel of a patient and relates to a blood transfusion apparatus including a chamber unit 10, an adjustment unit 20, an injection unit 30, It is safe blood transfusion device to prevent.

The blood transfusion apparatus 100 of the present invention selectively incorporates the chamber unit 10, the regulating unit 20 and the display unit for displaying the blood type on the injection unit 30, The main point is to prevent medical accidents in which patients and other blood are administered as they are checked repeatedly naturally.

That is, the present invention can be applied to a case where the chamber part 10, the control part 20, the injection part 30, and the display part which constitute the transfusion apparatus 100 are not the individual components, A blood vessel 20, and an injection unit 30 are integrally combined.

The chamber part 10 according to the present invention includes a filter 11 for removing impurities of blood to be transfused, and a dropping bottle 12 for supplying blood in a predetermined volume. 1, the chamber part 10 comprises a filter 11 and a drip tray 12, which is a container for inflowing (dropping) blood stored in a blood bag and transferring blood according to a predetermined usage. The filter 11 serves to remove blood clots and other debris, and allows the puncture container 12 to be filled with a predetermined volume (3/4) to prevent erythrocyte destruction at the time of blood clotting. The chamber part 10 is formed to be transparent so that the blood and the ingredient preparation can be visually observed. In other words, it is preferable that the display means is built in so that the blood type to be transfused can be naturally visually confirmed during the process of observing the chamber part 10 by the medical person.

The display means of the chamber unit 10 is provided with a sticker 15 attached to a predetermined size to display a blood type on the outer circumferential surface or a protrusion 17 integrally formed in a predetermined region. The sticker 15 is attached separately after the chamber part 10 is manufactured and the projection 17 is integrally formed in the process of manufacturing the chamber part 10. [ The sticker 15 and the protrusion 17 are appropriately sized so as not to block the blood flowing into the chamber part 10. [

The sticker 15 is separately attached to the filter 11 side and the dotted bottle 12 side. As described above, the filter 11 and the spotted tube 12 are integrally formed, but functionally different from each other, so that a medical practitioner can independently observe it. Therefore, it is preferable to separately attach to the filter 11 side and the spotted tube 12 side so as to have a further improved discrimination, but they may be attached to only one place depending on the case.

When the sticker 15 is separately attached, the filter side 11 displays a predetermined color for each blood type in a band shape. For example, if the blood to be transfused is of the A type in a state in which the A type is yellow, the B type is orange, the AB type is blue, and the O type is green, the sticker 15 printed in yellow as shown in FIGS. 11) side. These stickers 15 may be attached in plural to improve discrimination and aesthetics as shown in Figs. At this time, it is important that the sticker 15 is attached at the uppermost end so as not to cover the filter 11. In this way, the medical person observes the filter 11, and can identify the blood type to be transfused only by the inherent color of the sticker 15 attached thereto.

On the side of the dispenser 12, a character symbolizing the blood type is displayed. That is, if the blood to be transfused is type A, the sticker 15 printed with yellow 'A' is attached to the outer circumferential surface on the side of the drop chamber 12 as shown in FIGS. Here, the sticker 15 may be formed in a letter shape, but it is preferable that the sticker 15 is formed so as to have margins around the characters for adherence. In this case, it is important that the blank is formed transparently for observation of blood. In this way, during the process of observing the dispenser 12, the medical person can confirm the blood type to be transfused through the inherent color and the character of the sticker 15 attached thereto. Above all, it is possible to identify the type of blood that transfuses to patients and caregivers with easily identifiable characters.

On the other hand, the sticker 15 can be attached in various manners other than those mentioned above. That is, the strip-like sticker 15 may be attached to the side of the dotted cylinder 12, or the character sticker 15 may be attached to the filter 11 side. Only the band stickers 15 may be attached to the filter 11 side and the dotted bottle 12 side or only the character stickers 15 may be attached to the filter 11 side and the dotted bottle 12 side.

The protrusion 17 is formed by integrally injecting characters representing the blood type in the process of manufacturing the chamber part 10 as shown in FIGS. It is preferable that these protrusions 17 are formed only on the side of the drip tray 12 that the medical person observes relatively carefully. In other words, characters representing the blood type are formed to be transparent to the dot cylinder 12, and areas corresponding to the characters are formed to be opaque.

For example, if the blood type to be transfused is type A, the protrusions 17 are formed in a three-dimensionally protruding shape. At this time, the projections 17 are formed in the same transparent state as the dotted cylinder 12 by smoothly treating the surface. Here, a rectangular or circular protrusion 17 protrudes finely in a predetermined region including the character projection 17. [ That is, the fine protrusions 17 are formed to be opaque in contrast to the transparent character protrusions 17 by roughening the surface. Therefore, the character can be displayed in a unique color of blood. In this way, the blood type to be transfused can be confirmed from the protrusions 17 formed in the process of observing the dots 12 by the medical person.

On the other hand, the protrusions 17 may be formed independently of the pointed bar 12, but it is preferable that the protrusions 17 are formed in parallel with the stickers 15 attached to the filter 11 side for better discrimination.

The connection unit 20 according to the present invention includes a tube 21 connected to the pointed tube 12 to transmit blood and an adjustment table 22 for adjusting the amount of blood delivered on the tube 21. 1 and 2, the connection unit 20 includes a tube 21 and an adjuster 22 for transferring blood, which is introduced into the chamber unit 10, in a capacity. The tube 21 delivers blood from the chamber 10 to the patient as a long, thin transparent tube of soft silicone. The adjuster 22 is a valve having a roller that opens and closes the channel of the tube 21, and adjusts the amount of blood to be delivered. It is preferable that the controller 10 includes a display means so that the blood type to be transfused can be visually confirmed visually in the process of observing and adjusting the blood to be delivered.

As shown in FIGS. 1 and 2, the display unit of the controller 20 paints / coating a paint 25 having a predetermined color for each blood type so as to display a blood type on the outer peripheral surface. The paint (25) is a paint that does not dissolve in water or oil. That is, in the process of manufacturing the tube 21 and the adjustable table 22, the surface of the paints 25 of the previously designated blood type is painted and coated on the surface.

Here, the tube 21 is painted / coated in the shape of one or more lines on the outer circumferential surface, and the adjustment table 22 is painted / coated with characters symbolizing the blood type. At this time, the sticker 15 described above may also be attached to the tube 21 and the adjuster 22. However, since it is adjacent to the patient or the caregiver, there is a possibility that the sticker (15) is deliberately peeled off from nature.

Therefore, it is preferable to coat with the paint 25 in order to prevent such problems from occurring. In addition, since the surface of the paint 25 is coated with the transparent paint 25a, damage from the outside can be suppressed. In this way, the medical person observes the tube 21 and checks the blood type to be transfused from the paint 25 in the process of adjusting the adjustable table 22.

The injection unit 30 according to the present invention includes a blood transfusion belt 31 connected to the distal end of the tube 21 for supplying blood and a blood reservoir 32 for injecting blood into the patient on the blood transfusion base 31. [ Respectively. 1 to 4, the injection unit 30 includes a transfusion pedestal 31 and a handpiece 32 for injecting blood, which is delivered from a tube 21, into a blood vessel (vein) of a patient. The blood transfusing base 31 is a tubular needle for guiding the cannula 32 in a detachable manner from the tube 21 and for guiding the cannula 32 into the blood vessel of the patient. It is preferable that the injection unit 30 includes a display means so that the blood type to be transfused can be visually confirmed visually in the process of observing and adjusting the blood to be delivered.

The display means of the injection unit 30 is configured to display either a sticker 35 whose color is designated in dot form on a blood type basis by the blood type on the blood transfusing base 31 or a bracelet type label 37 which displays a color and a character symbolizing a blood type Selectively. Since the sticker 35 is the same as the sticker 15 described above with reference to FIGS. 1 and 2, the description and effects are omitted. However, since the size of the blood transfusing belt 31 is relatively small and narrow, it is preferable to display it in a dotted form.

The label 37 is formed into a bracelet as shown in Figs. 3 and 4 and attached to the wrist or ankle of the patient. The label 37 is formed from paper, fiber, or resin material, and is attached to the transfusable belt 31 with a cuttable ring 38. That is, in the process of transfusion, the loop 28 is cut to separate the label 37, and then attached to the patient's wrist or ankle. Here, the label 37 displays colors and characters representing the blood type on the outer circumferential surface. The label 37 may be provided with a sticker as shown in FIG. 5A or may be coated / coated as a paint as shown in FIG. 5C. Of course, stickers and paints may be used in parallel for better identification.

In addition, as shown in FIG. 5C, a barcode may be displayed as shown in FIG. 5D. In this case as well, the information field and the bar code may be used in parallel. In this way, the blood type to be transfused can be confirmed by the medical person through the attached label 37 in the process of injecting the blood vessel 32 into the patient. Further, the number of blood transfusions and various histories can be confirmed more accurately and quickly through the label 37 attached to the patient.

The blood transfusion apparatus 100 is shown in FIG. 1 as a display means incorporated in both the chamber portion 10, the regulating portion 20 and the injection portion 30, but may be optionally incorporated for the purpose of manufacturing. Of course, it is preferable to incorporate all of the display means in the chamber 10, the regulating portion 20, and the injection portion 30 in view of minimizing blood transfusion by repeatedly identifying the blood type.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
