Description

Miniature vein intensifier

This application claims priority to the previously filed provisional application No. 60/757,704, filed on Jan. 1, 2006, and which is hereby incorporated herein incorporated by In this article.

A miniature laser-based vein contrast enhancer that can be incorporated into a portable handheld product, and a medical practitioner can carry the handheld product in his pocket.

It is known in the art that a device can be used to enhance the visual appearance of veins in a patient, which facilitates the insertion of the needle into the veins. An example of such a system is described in U.S. Patent Nos. 5,969,754 and 6,556,858, the disclosures of which are incorporated herein by reference. Currently, the Luminetx device is sold under the name "Veinviewer Imaging System" and is available on its website, which is incorporated herein by reference.

The Luminetx Venous Contrast Intensifier (hereinafter referred to as LVCE) utilizes an infrared source for flooding the area to be enhanced by infrared rays generated by an array of light emitting diodes (LEDs). A photosensitive coupling element (CCD) imager is then used to capture an image of the infrared light that is reflected off the patient. The resulting captured image is then projected onto the patient at a location by a visible light projector that is precisely aligned with the image capture system. It is known that both the CCD imager and the image projector are two-dimensional and do not occupy the same point in space, and it is quite difficult to design and fabricate a system that precisely aligns the captured image with the projected image.

A further feature of the LVCE is that the imaging CCD and the projector have a fixed focal length. Accordingly, the patient must be at a relatively fixed distance relative to the LVCE. The LVCE needs to be positioned at a fixed distance from the patient area to be reinforced.

The combination of the size of the LVCE and the fixed focus configuration prevents the use of the LVCE as a small portable handheld unit.

It has been found that it is often difficult to administer one of the veins required for administration of intravenous solutions, drip, and the like. During venipuncture, whether or not it is used for an injection or instillation, it essentially penetrates a vein in exactly the right position. If a medical practitioner is only slightly biased, the needle will then be more likely to just roll away.

The present invention is a microvein strengthenr comprising a microprojection head and a mounting mechanism for the microprojection head. The microprojection head of the present invention performs a polarized laser light. This reduces the effect of specular reflection away from the surface of the skin. The Veinviewer imaging system produced by Luminetx uses a polarizing filter to polarize the LED light. This polarized LED light is then rotated 90 degrees in front of the camera, which results in increased power loss. In addition, the infrared (IR) and visible lasers of the present invention are modulated to allow a regular photodiode to individually detect different signals from each wavelength. Moreover, during each scan line, the IR laser power of the present invention is dynamically varied, thus increasing the operating range of the photodiode and allowing for constant direct current (DC) gain.

The microvessel intensifier of the present invention can be used by a medical practitioner to locate a vein and is particularly useful when trying to locate a vein in a very old or very young person. In older people who typically have a high percentage of slack, adipose tissue, and in children who typically have a high percentage of venules and "children's obesity", more than 50 percent of attempts to find a vein will not succeed. The present invention is directed to use in injection and blood testing to reduce and/or prevent discomfort and delay associated with awkward attempts to puncture a vein. Furthermore, the present invention can shorten the time it takes to complete a potentially life-saving intravenous drip.

Purpose of the invention

One of the objects of the present invention is to make a microvein strengthener that is cost effective to manufacture.

Another object of the present invention is to make a micro-vein strengthener that will allow a medical practitioner to pinpoint a vein for intravenous drip, blood test, and the like.

Yet another object of the present invention is to make a microvessel that will reduce and/or reduce the number of times an awkward attempt to pierce a vein.

A still further object of the invention is to make an easy to operate microvein strengthener.

Another object of the invention is to make a microvein strengthener that can be disposed of after use.

Still another object of the present invention is to make a miniature vein strengthener that can be held by hand.

Still another object of the present invention is to make a microvein strengthener that provides a miniature projection head in an alternating frame mode.

Still another object of the present invention is to make a microvein strengthener that provides a miniature projection head that operates in a Dual Buffer Mode.

Still another object of the present invention is to make a micro-vein strengthener that provides a miniature projection head that operates in a Real Time Mode.

Fig. 1 shows a Miniature Vein Enhancer (MVE) 1 for reinforcing a target area 4 of a patient's arm 3. The MVE 1 has a Miniature Projection Head (hereinafter referred to as MPH) 2 for imaging the target area 4 and for projecting a strengthened image 11 onto the target area 4 along the optical path 5. This MPH will be described in detail later with reference to Figs. 18 to 21. The MPH 2 is placed in a cavity area, preferably in the top cavity area 12 of one of the MVEs. The body 13 of the MVE 1 is positioned below the top cavity region 12. The body 13 has a vial opening 8 for receiving a vial holder 7 having an injection needle 14 and temporarily holding it in place. The body 13 also has a thumb opening 9 through which the practitioner 6 can place his thumb 10 when using the MVE1. The vial opening 8 is preferably provided with at least one curved base region 8A for receiving the curved outer surface of the vial holder 7 and holding it in place. The thumb opening 9 can be a separate aperture or it can be part of the vial opening 8.

The function of the MVE in Fig. 1 is as follows. A medical practitioner 6 puts a standard vial holder 7 into the vial opening 8. The vial opening 8 is shaped such that it holds the vial holder 7 in place. The MVE 1 is preferably operated by a battery and is opened by the medical practitioner 6 via an unillustrated on/off switch. Alternatively, the unit can be turned on/off by a switch that detects whether the vial holder 7 is present in the vial opening 8. The practitioner 6 will place his thumb 10 through the thumb opening 9 and support the bottom of the vial holder 7 with his index finger. When grasping a vial holder for insertion into the patient's vein, this mimics the normal grip used by many practitioners. When the MVE 1 is brought close to the patient's arm 3, the MPH 2 takes an image of the vein 11 of the patient 3 in the target area 4. After receiving the image, the MPH projects the visible images of the veins along the optical path 5 onto the target area 4.

The portable size of the MVE provides many advantages over the prior art unit. The prior art unit is too large to be held in one hand and is in fact fixedly mounted or mounted on a rolling cart. The present invention is small enough to be carried by hand for mobile workers such as doctors, nurses, emergency health workers, military personnel, police, and family-drawn blood draws. The portable MVE can move rapidly over the body of the patient, thereby viewing a large number of veins over a short period of time. Furthermore, the one-handed operation of the MVE allows the caregiver's second hand to be used for other purposes.

The 2A-2F diagram further illustrates the MVE1 of Fig. 1 in more detail. Figure 2A shows the top void region 12 separated by the body 13. At least one, but preferably two, holes 15 for removably mounting the top aperture region 12 to the body 13 are positioned on each side of the top aperture region 12. Figures 2B and 2C show the body in two different perspective views. The body has a protruding portion 16 that is shaped to fit into the aperture 15 in the top aperture region 12, thereby facilitating attachment of the body 13 to the top aperture with a removable hairline Area 12. As will be appreciated by those skilled in the art, the apertures 15 can be in the body 13 and the projections 16 can be in the top aperture region 12. The 2C and 2D views show the body 13 and the top aperture area 12 has been removed. A transverse member 18 is coupled to the left wall surface 20 and the right wall surface 21 at a pivot point 17. When the release button 19 is squeezed together, the bottoms of the left wall surface 20 and the right wall surface 21 are removed, and the size of the vial opening 8 is increased, thereby releasing the vial holder 7 (not shown). The pressure on the support. When the top cavity region 12 is inserted back into the body 8, the top cavity region 12 exerts an outward force on the top of the left wall surface 20 and the right wall surface 21, thereby reducing the size of the vial opening 8 thereby It is ensured that the vial holder 7 is in close contact with one of the bodies 13. Similarly, the inward pressure on the left wall 20 and at the bottom of the right wall 21 exerts an outward force on the top of the left and right wall faces 20, 21, allowing the top hole region 12 to be easily inserted into the left wall of the body. Between the right side wall and the wall.

Further details of the body 13 are shown in Figures 2E and 2F. 2E is a rear view of the body 13, and FIG. 2E is a side view of the body 13. The removable top aperture region 12 is snapped into place in the body 13 and held in place by the projections 16, the projections being inserted into the apertures 15 (in Figures 2E and 2F) Not shown). When the left wall surface 20 and the right wall surface 21 are pressed toward each other, the protruding portions 16 are detached from the holes 15.

Figures 3A-3F show another embodiment of the invention. Figures 3A-3F also show the order in which one of the MVEs is used. In Figure 3A, the MVE1 is similar to the MVE of Figures 2A-2F except that it has a top cavity region 12 that is attached to the body 13 in a fixed manner. The bottom of the body 13 has two sides 30 and 31 extending downward, and an opening for receiving the vial holder 7 is provided at the bottom. The two sides 30 and 31 can generally be biased to create a tight friction fit around the vial holder 7, but as shown in Figure 3A, the thumb and index finger can be used in the left hand of the practitioner. Next, the vial holder is released by simultaneously pressing the points on the body to allow easy attachment between the vial holder 7 and the MVE1.

The first step of the operation is shown in Figure 3A, wherein the practitioner 6 holds the body 13 of the MW1 and squeezes the body (between the thumb and forefinger) to release the bias of the two sides 30 and 31. . The practitioner 6 then takes a new vial holder 7, positions it between the two sides 30 and 31, and releases the pressure between the thumb and index finger, thereby allowing the sides to move toward the vial The normal biased position around the support 7. The MVE1 is now attached to the vial holder 7 in a removable manner. Further, here, the vial holder 7 is made of an elastic material which can press the vial holder 7 to release the vial holder from the body.

The second step of the operation is shown in Figure 3B, wherein the practitioner activates MPH2 (not shown in these figures) contained within the head of the top void region 12. Figure 3B shows that this actuation is performed by depressing one of the buttons 32 on the top of the MVE 1, or that the unit can be automatically initiated when the MVE is attached to the vial holder 7.

Figure 3C shows that the practitioner 6 approaches the arm of a patient 3 with the MVE1. The optical path 5 and the field of view 4 of the MVE 1 are shown in Fig. 3C. At this time, the veins 11 of the three arm of the patient are visually projected onto the patient's arm by the MPH2. A significant advantage of the MPH 2 for a hand-held configuration is that the image in the field of view 4 is always in focus regardless of the distance from the MPH 2 to the patient 3. Since the distance between the MPH 2 and the patient is continually decreasing as the MVE 1 approaches the patient 3, prior art systems with limited field of view will not function properly in this particular embodiment. It should be further noted that the medical practitioner only needs to manipulate the vial holder 7 with one hand and support the MVE1 at this time. The remaining second hand can be used for other work.

It should be further noted that the tip of the injection needle 14 is within the optical path 5 of the MPH 2. Accordingly, the practitioner can move the MVE1 over the arm of the patient 3 and view the entire venous structure of the patient. When the practitioner wants to approach the particular vein with the needle 14 or even when the needle hits the surface of the patient, the vein remains within the field of view. The prior art systems have a fixedly mounted imager and projector such that to view a large area of the patient's body, the entire projector must be moved relative to the patient or the patient must move relative to the projector.

Figure 3D shows the practitioner inserting the injection needle 14 of MVE1 into the vein 11 of the patient. It should be noted that in steps 3C and 3D, only one practitioner of the medical practitioner is required.

Figure 3E shows that the practitioner 6 initially removes MVE1 from the vial holder 7 by squeezing the tops of the side walls 30 and 31 between his thumb and forefinger, thereby reducing the vial branch. The pressure on the tray 7.

Figure 3F shows that the MVE1 has been removed from the vial holder 7. The MVE1 can then be put aside for future use. The medical practitioner can perform all the work at this time, and the work is usually performed after the vial holder is inserted into the vein of a patient.

The specific embodiment of Figures 3A-3F utilizes a standard cylindrical vial holder 7, and relies on the pressure between the side arms 30 and 31 to hold the vial holder in place. Accordingly, the existing standard vial holder 7 can be utilized. It will be appreciated by those skilled in the art that a vial holder having a cross-section other than a cylindrical shape can also be used by modifying the inside surface of the side arms.

However, it is intended to utilize a new vial holder that has the feature of allowing the vial holder to be more securely attached to the MVE1. Figure 4A illustrates a top view of the new vial holder 40 and the side arms 42 and 44 of an MVE. The vial holder 40 has four recesses 41, two recesses on one side of the cylindrical body, and the two recesses directly facing each other. The side arms 42 and 44 of the MVE have four projections 43 that are slightly smaller in size than the notches 41. When the side arms 42 and 44 are moved toward the vial holder 40, the projections 43 are inserted into the recesses 41 and thereby prevent the vial holder 40 from moving relative to the MVE.

As a further example of the mounting embodiment shown in Figure 4B, the side arms 47 and 48 can be bent to form the circular vial opening 8 of Figure 1. Furthermore, the arms are further configured to have a recess 45 having two recesses on each side arm, and the arms can be positioned to receive the protruding portion 46, the protruding portions being tied The vial holder 40 of this embodiment is incorporated. Accordingly, when a drug bottle holder having a protruding portion is utilized, as shown in FIG. 4B, the MVE and the vial are locked due to the engagement of the protruding portion 46 and the notches 45. The parts are strong. Alternatively, when using the existing vial holder 7 shown in Figure 1 (without such projections), the unit will function as described in Figure 1 and from the sides of the bend The arms 47 and 48 hold the MVE and the vial holder together against the pressure of the vial holder 7. These notches 45 will not be used only in this case. Accordingly, the MVE having the side arm shown in Fig. 4B can be used by the existing vial holder, or can be used together with the new vial holder shown in Fig. 4B.

Although FIGS. 4A and 4B illustrate the installation configuration between the vial holder and the MVE, the present invention is not limited thereto. For example, many other types of removable mounting configurations are contemplated, such as a detachable mounting configuration utilized between the razor and the razor blade.

The manufacture of MVE using the new vial holders of Figures 4A and 4B will enable the sale of a system comprising a single MVE and a majority of the spent bottle holder 40. Furthermore, it is possible to establish a consumable commercial transaction for a bottle of medicine that is used up and lost, as shown in Figures 4A and 4B.

Figures 5A-5C show various views of another alternative mounting embodiment for MVE. In this particular embodiment, the MVE 50 is attached to a solid entrainment 51. In one embodiment, the MVE 50 can be coupled to a mounting plate 52 that is sequentially bound to the back of the practitioner 6 by a solid entrainment 51. Preferably, the MVE 50 is rotatably mounted on the mounting plate 52. A connecting portion rotatable between the MVE 50 and the mounting plate 52 allows the MVE 50 to rotate about the first axis 53 and also about a second axis 54 that is horizontal to the hand; the first axis is vertical On the back surface of the hands of such users. The MPH 2 (not shown) is placed within the MVE and projected along the optical path 5 to the field of view 4 (in the same manner as described earlier with reference to Figure 1). By rotating the MVE 50 on the mounting plate 52, the practitioner can aim the optical path 5 such that the field of view 4 is positioned around the tip of the needle 14. Figure 5B shows a top view of the MVE 50 of this particular embodiment. Figure 5C shows the bottom of the hand of the practitioner 6. The clip 51 can be attached by a Velcro 55 or other suitable mechanism to enable the practitioner to easily attach and detach the MVE 50.

Figure 6A shows yet another alternative installation embodiment for an MVE. In this particular embodiment, the MVE 60 is attached to a solid entrainment 61 that extends around the head of the practitioner 6. The MPH 2 (not shown) is placed within the MVE 60 and projected along the optical path 5 to the field of view 4 (in the same manner as described earlier with reference to Figure 1). By moving his head, the practitioner 6 can easily move the optical path 5, thereby placing the field of view 4 at any desired location on the patient. If the MVE 60 is positioned such that when viewed forward, the optical path 5 generally corresponds to a line of the position of the medical practitioner 6, the configuration of the field of view 4 on the patient will be very natural for the practitioner 6. The securing strap 61 can be attached by a Velcro (not shown) or other suitable mechanism to enable the practitioner to easily attach and detach the MVE 60.

Figure 6B shows the MVE 60 of Figure 6A in more detail. The MPH 2 (not shown) is housed in an adjustable outer casing 62 that is removably coupled to a base 63. In this embodiment, the relationship between the adjustable outer casing 62 and the base portion 63 may be in the form of a ball and a socket. The adjustable outer casing 62 is preferably circular and the base 63 is a corresponding recessed socket. The practitioner can rotate the adjustable outer casing 62 within the base 63 to change the direction of the optical path 5 relative to the head of the practitioner. In this manner, mounting the MVE 60 to the head is less precise, and the optimization of the direction of the optical path 5 is adjusted by moving the adjustable outer casing 62 within the base 63. This embodiment is completely unobstructed by the practitioner's hands and allows the image field of view 4 on the patient to be easily moved by the practitioner's simple head movement.

Figure 7 shows yet another embodiment of the MVE which is particularly preferably adapted for use in accessing a vein in the arm 3 of a patient. In the current practice, tourniquets are typically placed around the biceps of the arm to enlarge the veins of the arm and make them easier to insert into the needle. In this particular embodiment, the MVE 70 is mounted on a tourniquet 71 that is placed around the biceps of the patient 3. The tourniquet 71 can be tied around the biceps and held tightly by, for example, the Velcro segment 72. When the arm 3 is tied tightly, the MVE 70 can be oriented such that the optical path 5 from the MPH (not shown) disposed within the MVE 70 is directed toward the target vein 73 on the arm. In this way, the MVE is held in place and the practitioner 6 has both hands that can be used for other applications.

Figure 8 shows another embodiment of the MVE. In this particular embodiment, the MVE 80 is mounted on a substantially transparent plastic or glass base 81 that can be placed on the arm of the patient 3 by the practitioner 6. The base 81 has a curved bottom portion 82 that approximately conforms to the shape of the arm of the patient 6. If the patient 3 does not move his arm violently, the MVE 80 will remain in place without the medical practitioner holding the MVE 80. If desired, the base can be provided with openings on sides 83 and 84 near the area where the base contacts the patient's arm to receive a solid entrainment or other mechanism to secure the MVE to the arm without unnecessarily Block the view of the veins. The MPH (not shown) is positioned within the MVE 80 and positioned such that the optical path descends from the MVE to the arm, causing the field of view 4 to land on the patient's arm. The curved bottom portion 82 is also concavely curved inwardly to provide an unobstructed access to the vein of the patient. In this particular embodiment, the base 81 needs to be relatively transparent to allow a visual image of the vein projected by the MPH (not shown) within the MVE 80 to pass the base of the patient 6 through the base 81 to the viewer. One advantage of this embodiment is that because the MVE 80 is portable, it can be quickly positioned on the patient's arm 3 and can be quickly removed after use and when the practitioner 6 continues his work It is placed on this side.

Figure 9 shows an embodiment of the MVE wherein the MVE 90 is mounted on an adjustable arm 92 that is coupled to the MVE 90 at one end and to the other end A base 91. In this particular embodiment, the arm 92 is shown as a gooseneck-type arm, although other configurations are possible. The base is shaped to comfortably support the arm of the patient 3. The gooseneck arm 92 is such that it can be moved and rotated by the medical practitioner 6, but after it is moved or rotated, its set position is maintained. Gooseneck-type arms are well known in the art and need not be further described herein. The MPH 2 (not shown) is disposed within the MVE 90 and is projected along the optical path 5 to the field of view 4 . The operation of Fig. 9 will now be described. The patient 3 places his arm on the base 91 with the elbow facing down. The practitioner 6 opens the MVE 90 via a switch (not shown). Alternatively, the MVE 90 can be automatically opened when one of the pressure sensors in the base 91 detects the presence of an arm positioned thereon. The practitioner 6 then moves and rotates the MVE 90 until the field of view 4 falls on the desired vein 11, which remains in a fixed position on the patient's arm. The medical practitioner can then release the MVE 90 and then proceed to access the vein 11.

Figure 10 shows a specific embodiment which is similar to Figure 9 except that the support member 101 is wider and can support a larger weight. The MPH is placed in the MVE 100 such that the optical path of the MPH exits through an opening 103. Moreover, the embodiment of Fig. 10 includes a touch display 102, for example, the medical practitioner can adjust parameters of the MPH (not shown), such as the brightness, contrast, and projection angle of the MPH, through the touch display.

11A-11D shows a specific embodiment in which the MVE 111 is removably mounted to an existing blood drawer chair 110 having an armrest 112 that is a patient when the practitioner is approaching his vein. Can rest his arm on the armrest. The MPH (not shown) is mounted in the top portion 113 and is projected along the optical path 5 to a field of view 4 positioned on the armrest 112. The top portion 113 is mounted to the bottom portion 114 in such a manner that the top portion 113 can slide up and down relative to the bottom portion 114, thereby increasing and decreasing the distance from the MPH to the armrest 112. As the distance increases, the field of view 4 becomes larger, but the brightness at a particular location within the field of view 4 decreases. Conversely, as the distance decreases, the field of view 4 contracts, but the brightness at a particular location within the field of view 4 increases.

Figures 11C and 11D show in more detail an example of how the MVE 111 can be attached to the armrest 112 of the chair 110. The bottom portion has a "C" shaped structure 115 that can be placed over the armrest 112. A screw mechanism 116 can be rotated to attach the MVE 111 to the armrest 112. One skilled in the art will appreciate that there are other types of mechanisms for securing the MVE 111 to the armrest 112.

Figure 12B shows a prior art vial holder 123 to which prior art injection needle protector 120 has been attached. When a medical practitioner finishes using the vial holder 123, the practitioner uses a disposable surface to push the needle protector 120 over the needle 124 prior to removal, thereby preventing accidental injections. Needle marks. The needle protector has a main body 121 and a circular mounting ring 122 that fits directly over the front surface of the prior art vial holder 123. Figure 12A shows the prior art needle protector 120 separated by the vial holder 123.

Figures 13A-13E show a needle holder 125 in accordance with the present invention that is capable of supporting an MVE. The needle holder 125 has a main body 126 and a circular mounting ring 127 that fits directly over the front surface of a prior art vial holder 123. In addition, the needle holder also has a thumb support portion 128 on the base of the needle holder 125.

Figure 13B shows the needle holder 125 attached to a prior art vial holder 123 of Figure 13A, and the MVE 131 temporarily attached to the needle holder 125. An MVE 131 has a main body portion 130 that houses the MPH 2. The main body portion 130 is rotatably coupled to a header portion 129, in which manner the main body portion can be rotated by a medical practitioner to thereby rotate the optical path 5 up or down. The connection between the header portion 129 and the main body portion 130 is sufficiently rigid that the medical practitioner releases the main body portion even after the medical practitioner moves the main body portion 130 upward or downward. After 130, it remains in this position. The socket portion 129 of the MVE 131 has an opening at the bottom that is shaped to receive the top of the main body 126 of the needle protector 125. When the socket portion 129 of the MVE 131 is placed over the top of the main body 126 of the needle protector 125 and a slight pressure is applied therebetween, the two components temporarily snap together. When snapped to the top of the main body 126, the locking mechanism is designed to rotate the socket portion 129. The assembly between the two components is sufficiently tight that no further rotation occurs after the header portion 129 is rotated by the medical practitioner, unless and until the medical practitioner rotates the socket portion 129 again.

When the needle protector 125 is attached to the vial holder 123, a thumb support portion 128 is in contact with the vial holder 123. When the vial holder is used and the MVE 131 is attached, a medical practitioner positions his thumb on top of the thumb support 128 and positions his food on the opposite side of the vial (on the thumb Opposite the support). In this manner, the medical practitioner supports the vial holder 123, the needle protector 125, and the MVE 131 with one hand. The practitioner can move to the main body portion 130 of the MVE such that the optical path 5 is aligned such that the field of view includes the tip of the needle. After the medical practitioner inserts the vial holder 123 into the vein of the patient, the MVE 131 can be separated by the needle protector and placed down on a surface. During this process, the blood can be withdrawn in the same manner as the prior art system of Figure 12B. Upon completion of this activity, the vial holder 123 and the needle protector 125 can be discarded.

Figures 14A and 14B show a particular embodiment in which the MPH 2 is integrated into a magnifying lens housing 143 that supports a magnifying lens 140. The magnifying lens housing 143 is coupled to a clip 144, such as via a gooseneck or other type of support member 141, which can be sequentially mounted to a platform, a limb of a blood drawer chair, or other suitable support member. The MPH 2 is positioned within the magnifying lens housing 143 such that the optical path 5 is aimed downward toward the platform or the arm of the chair. When a patient 3 places his or her arm on the platform, the field of view 4 falls on the arm. As shown in FIG. 14A, when the medical practitioner views through the magnifying glass 140, a magnifying image 145 of the vial holder 142 and the vein of the patient 3 is provided within the field of view 4 of the patient. Inserting the vial holder into the vein of the patient allows viewing of the magnified image to allow for greater accuracy.

As still further embodiments, the magnifying lens 142 of Figures 14A and 14B can be replaced with a flat panel display. In this case, the MPH 2 only has to take an image of the needle of the vein and the vial holder 142 within the field of view 4 and does not need to repeatedly transmit a visible image to the arm. Additionally, the vein and the visible image of the needle are delivered to the flat panel display 142 and are viewed by the practitioner when the needle is inserted into the vein. In this embodiment, the medical practitioner does not directly view the needle or the arm, but views an image thereof in the flat panel display 142. The image in the flat panel display 142 can be zoomed in or out (zoomed) in a digital manner as desired by the medical practitioner. The control of the zoom can be input to the flat panel display via a touch screen.

Figures 14C and 14D show two perspective views of yet another embodiment of an MVE 150. In this particular embodiment, the MVE 150 includes a small display 151 that is viewable by the practitioner along viewing angle 157 and to which an attachment 154 and an MPH 2 have been attached. Although the attachment is shown to be at right angles to the stem extending perpendicularly from the vial, the stem can be angled relative to the vial and the display angle can be varied as well. An injection needle protector 156, similar to that shown in detail in Figure 13A, is coupled to a vial holder 7. The attachment member 154 receives the top of the needle protector and temporarily locks the MVE to the needle protector 156 and sequentially attaches to the vial holder 7. The MPH 2 is attached to the small display 151 and guided such that the optical path 5 is such that the field of view 4 covers the tip of the injection needle 14. The MPH 2 outputs the image of the vein 11 to the field of view 4 of the patient (not shown). The MPH 2 also provides the image signal to the display 151 for viewing on the display 151. The image signal includes both the veins and the injection needle 14. The display 151 includes image processing capabilities for detecting the position of the tip of the needle and displaying a predetermined number of pixels surrounding the image of the tip of the needle on the display. In Fig. 14C, the image of the needle 153 and the image of the vein 152 are displayed.

An example of using the MVE 150 of Figure 14C is as follows. A medical practitioner selects a disposable sterile vial holder 155 to which the needle protector 156 has been attached. The needle protector 156 is moved to a right angle position relative to the needle 14, thereby exposing the needle. The MVE 150 is coupled to the top of the needle protector 156 via the attachment 154. The MVE system is then opened and the MPH 2 receives images of the vein 11 and the injection needle 14 within the field of view 4. The practitioner will move the MVE 150 around the patient and view an image of the vein 11 projected onto the patient. The image of the vein will be the actual size and location of the patient's vein. When a vein is selected for piercing the needle, the practitioner brings the needle to the vein while still viewing an image of the vein on the patient's body. When the medical practitioner approaches the selected vein with the tip of the needle, the practitioner will look at the image of the display 151, which is the magnified image of the needle tip of the needle 153 and the target vein 152. By using this magnified image, the medical practitioner can pierce the center of the vein 11 with the injection needle 14 without fail.

The display 151 can be so small that it requires only a single vein and an enlarged view of the needle. As shown by the examples 28A and 28B, wherein the 28A map represents the image of the vein 11 on the patient in the field of view 4, and the 28B map represents the image and injection of the vein 152 displayed on the display 151. An image of the needle 153. In this example, the target venous system is crossed by 0.10 吋, and the field of view 4 is 3 inches multiplied by 3 inches, and the resolution of the image taken and projected by the MPH 2 in the field of view is multiplied by 1000 pixels. 1000 pixels. In this example, the MVE can be programmed to display on the display 151 an area of 300 pixels multiplied by 300 pixels centered on the needle of the display. Referring to Figure 28B, the resulting enlarged image of the vein 152 is shown to be more than three times greater than its original width. It will be appreciated that the amount of amplification (the amount of zoom) on the display 151 can be adjusted in a computational manner by the processor in the display. The practitioner can provide input to select the appropriate amount of gain.

Another alternative embodiment is shown in Figure 14E, in which the display 151 of Figures 14C and 14D is replaced by a rear projection screen 158. The MPH can be configured to project a split image. The bottom half represents the actual image of the veins 11, and the top half is an image of the enlarged image of the veins and needles. A mirror 159 is placed in the optical path 5 of the top half of the image projected by the MPH 2. The mirror 159 is angled such that the top half of the image is projected onto the rear projection screen 158 along the optical path 5B. The rear projection screen is translucent and can be viewed by the medical practitioner along viewing angle 157. In this manner, a display screen can be obtained without increasing the cost, size, and power of the dedicated display of Figures 14C and 14D.

In yet another embodiment, as shown in Figures 15a-15d, the MVE can have a disposable tray 200 that can include a substantially "C" shaped base clip portion. 201. The base 201 can be made of the same material as the previous embodiment. In the preferred embodiment, the MVE support 200 can be molded from a clear plastic. Any suitable transparent plastic known in the art can be used, including, but not limited to, polyvinyl chloride, polystyrene, acrylic, and the like. Extending from the base 201 can be an arm 202 having a concave bottom corner 203 and a raised top corner 204. The two corners can be integrally formed with the base 201. The arm 202 can have an inner side surface 205 and an outer side surface 206. Located between the top corner 204 and the bottom corner 203 of the arm 202 may be a second substantially "C" shaped clip 209. Positioned at the top of the MVE 200 can be a generally circular ring portion 207. The annular portion 207 can be a unitary member of the MVE bracket 200, or the ring 207 can be a separately attached member. In a preferred embodiment, the ring 207 is integrally formed with the bracket 200. In addition, the ring 207 can have a generally circular threaded outer top surface for use as a male end, or the ring 207 can have a generally circular grooved inner surface for use as a The parent side will now discuss its utility.

As with the specific embodiment described above, the MPH 208 will be operable by this embodiment, however, in this embodiment, the MPH 208 may have a threaded outer surface or a grooved inner side surface, and This will have a priority importance. For example, if the ring 207 has a side surface provided with a groove, the MPH 208 will have a corresponding inner surface provided with a groove, which will be attached and removed to the medical practitioner before and after use, respectively. The ability of the MPH. In normal operation, the practitioner will snap the clip 201 to the prior art vial 220. In addition, the practitioner will snap the clip 209 to the prior art needle protector 221. After the clips 201 and 209 have been attached, the practitioner can then attach the MPH 208 to the ring 207. This will be done by the two aforementioned attachment methods. It should be noted that the practitioner may also attach the MPH 208 to the ring 207 prior to attaching the rings to the vial.

Once the MVE is attached in a fixed manner, the medical practitioner can then proceed with the foregoing procedure. Upon completion of the procedure, the practitioner will then apply a pressure to the surface 206 sufficient to push the needle protector 221 and the arm 202 above the used needle 223, after which the MPH is intended for future use and can be discarded from the needle and MVE.

Another embodiment of a disposable MVE stent 302 can be seen in Figures 16a-16c. A specific embodiment of this version can include an MPH 301, a holder 302, and a vial 303. MPH 301 can have the same operational features as the aforementioned MPHs. Bracket 302 can be made from any suitable conventional material in the art, including, but not limited to, metals, alloys, plastics, plastic composites, and the like. In a preferred embodiment, the bracket 302 can be made of plastic. Plastic is preferred because of its cost-effectiveness and hygienic quality. As previously mentioned, the MPH 301 can be operated in the foregoing specific embodiment, however, in this embodiment, the unique holders are brackets 304 and 304a located on the MPH 301 and the vial 303, respectively. Bracket 304 can be any suitable shape as is known in the art. In a preferred embodiment, bracket 304 has a generally rectangular shape. Additionally, the bracket 304 can have an aperture 307 that extends from a front end 305 to a rear end 306 or partially passes therethrough. In a preferred embodiment, the aperture 307 does not extend the full length of the bracket 304 as shown in Figure 23a. The aperture 307 can have a smaller diameter than the holder portion 309 of the bracket 302. The bracket 302 can also have a locator portion 310. It should be noted that the locating member 310 and the holder 309 are substantially identical in shape and size to each other as seen in Figures 23b and 23c, and can be used interchangeably in the preferred embodiment. .

As described above, at least one side of the vial 303 may be another bracket 304a. In a preferred embodiment, the bracket 304a can be substantially the same size and shape as the bracket 304. However, we can provide different sizes and shapes for any of the brackets and/or arms. The bracket 304a may also have an aperture 307a as in the bracket 304 that extends from the front end 305a to the rear end 306a. In the preferred embodiment, the two brackets have apertures that extend the same length equally. One difference between the brackets 304 and 304a is that the bracket 304 is slightly rounded to fit the MPH 301. In another embodiment, the MPH can have a flat base, in which case the bracket 304 cannot be made circular. Brackets 304 and 304a can be located anywhere on MPH 301 and vial 303, respectively. In normal operation, the practitioner can insert the holder arm 309 into the aperture 307 and insert the keeper arm 310 into the aperture 307a. Once inserted, the practitioner can move the MVE to the desired location. Since the individual carrier apertures have a smaller diameter than the individual arms they are subjected to, the pressure relied upon will prevent the MPH from moving during the procedure.

The drawings of Figures 17a-17d, which are now drawn to our attention, are another embodiment of the present invention. In this particular embodiment, the MPH 401 operates in substantially the same manner as previously discussed with the specific embodiments. A unique feature of this embodiment is the mounting bracket 400, which also has the function of a needle cover. The mounting bracket 400 can include a post portion 402 and a ring portion 403 that is hinged to the post 402.

In another embodiment, the MPH 701 can have its front face raised above the plane of the surface 703, and in the third embodiment, the MPH 701 can have its front face recessed below the plane of the surface 703. As mentioned above, the specific embodiment of the MVE can be hand held or attached to a vial, as in other embodiments. This configuration can be observed on pages 25c and 25d. If the latter method of use is used, i.e., attached to a vial, the needle cover 710 can have a generally rectangular top portion 711 having a width large enough to receive the MVE. Additionally, the inner side of the top portion 711 can be at least one tab portion 712 for engaging the groove 709 as seen in Figure 32d. Conversely, there may be at least one groove on an inner side surface of the top portion 711, and the top or bottom surfaces 702 and 703 may each have an outer generally elliptical tongue. The operation of this particular embodiment is similar to the specific embodiments previously discussed.

Additional embodiments of the second aspect of the invention can be found in Figures 26a-27d. First, this specific embodiment is described in Figures 26a-26d. This embodiment includes an MPH that can be either hand-held as shown in Figure 26d or mounted to an injection needle cover 802 as shown in Figure 26b. In this latter configuration, the operation of the MPH installation is similar to other prior embodiments. The MPH has an adjustable rear end 801 that can have an aperture 803 to receive the top 804 of the needle cover 802.

In this particular embodiment, the battery holder 810 can be substantially pear shaped and has a wider rear end 811 and a tapered front end 812. Located near the front end 812 may be a generally rectangular recess 813 in a drilled manner. The inner side of the groove 813 may be at least one joint. The rear end 804 of the MPH 805 may be substantially the same shape as the drilled groove 813. The surface located on the rear end 804 may also be at least one joint. In normal operation, the practitioner can slide the rear end 804 from either side of the left or right side or insert the MPH 805 rear end 804 into the recess 813 from the front end.

Specific embodiments similar to those described above are the specific embodiments described in Figures 27a-27d.

The MPH 2 will now be described. Figure 29 shows a prior art of Microvision's scanning laser based camera (hereinafter referred to as SLBC) 170. Figure 17 is taken from the website of Microvision Corporation on the date of January 7, 2006: (http://www.microvision.com/technology/imaging_works.html), which is incorporated herein by reference. The SLBC 170 includes a laser source 171 that reflects the laser source away from the mirror 172 to a Micro-Electro-Mechanical System (hereinafter referred to as MEMS) scanner 173. The MEMS scanner 173 has a reflective surface that can vibrate in both the X and Y axes. The vibration of the MEMS scanner 173 is controlled by an electronic device (not shown) such that the reflected laser beam moves in a raster pattern. To make a color camera, the laser source is a combination of red, green, and blue lasers, thereby forming the color white. Three photodetectors are positioned on the SLBC 170 and receive raster laser light that reflects away from the object 176, with one responding to red light 175R, one responding to blue light 175B, and one responding to green light 175G. The outputs of the photodetectors 175R, 175B, and 175G provide an analog image representation of the object 176. The outputs of the photodetectors are converted from a analog signal to a digital signal by a digital/analog converter (not shown). A controller (not shown) determines the instantaneous raster laser position and converts it to a suitable pixel position. The controller then writes the digitized RGB values to a suitable pixel memory location. By repeating this step for each pixel location, a digitized version of the object is stored in memory. Each raster pattern scan of field of view 4 results in a new image to be stored. Video images can be taken by scanning in the video ratio.

The SLBC of Figure 29 is even more detailed in the announcement of the laser focus world by Chris Wikdof in December 2004, titled "Laser Cameras for Display Technology", which is cited by reference. Into this article.

Figure 30 illustrates a specific embodiment of the invention illustrating MPH 2. A monochromatic laser 180, such as a 630 nm semiconductor red laser, is projected into the combiner 181. A semiconductor laser 183 system is also projected into the combiner 181. The laser 183 can have a frequency from 700 nm to 1000 nm, and a preferred frequency is 740 nm. An illustrative example of a semiconductor 740 nm laser is Sacher Lasertechnik's Fabry Perot diode laser 740 nm, 10 mW, and model FP-0740-10. The combiner 181 outputs a combined laser beam 184 which is a combination of the 630 nm red light and the 740 nm laser beam. Combiners for combining two lasers of different frequencies are well known in the art and will not be further described herein. The combined laser beam 184 is positioned to impact away from the mirror 172 and then strike the MEMS scanner 173. The MEMS scanner moves in a grating pattern whereby the combined laser beam moves along the optical path 5 and forms a grating pattern in the field of view 4. A pair of photodetectors 182 that respond to the 740 nm frequency are provided and receive 740 nm of light reflected off the object in the field of view. The photodetector 182 outputs an analog signal representative of the amount of 740 nm light received. An illustrative example of a photodetector is Roithner Lasertechnik, model EPD-740-1.

Figure 31 shows a control block diagram for controlling the components in Figure 30. The following is the first mode of operation, which will be referred to as an "alternating frame mode" (AFM).

In the AFM mode, an electronic block 192 is provided for driving the MEMS driver and for sensing the position of the raster pattern scanner. This block produces the signals required to drive the MEMS scanner 173 in a raster pattern and also determines the correct instantaneous location of the MEMS scanner and enables this information to communicate with an image memory 191. The electronic block 192 also generates an output signal and indicates whether the current frame (a frame is a complete raster pattern of the field of view) is a singular frame 1 or an even frame 2 (essentially the two signals are opposite) , and the polarity is switched every other frame). This operation is as follows. The MEMS 173 is driven in a raster mode. After a stable raster pattern is achieved, the first complete frame will be identified as a singular frame, and the laser driver 195 for the raster pattern is opened for the entire frame. During this time, the laser driver 194 for the 630 nm laser is turned off. The light from the 740 nm is absorbed by the veins in the body of a patient and reflected by the skin of the patient, thus forming a contrast image that is then sensed and passed through 740 nm. Photodetector 182 converts to an analog signal. The analog signal is then passed through an analog/digital converter 190 that outputs a digital picture to the image memory 191. The image memory 191 also receives the instantaneous location information from the electronic block 192, and based on the information, the digital picture is stored in a memory location corresponding to a particular pixel. This is repeated for each pixel in the odd frame. When the odd frame is completed, the image memory contains an image of a vein within the field of view of the MPH. During the even frame, the 740 nm laser laser driver 195 is turned off. The data in the image memory 191 can be read as a function of the instantaneous location information provided by the electronic block 192 and provided to the digital/analog converter 193, which outputs an analog signal to the laser driver 194. The laser driver drives the 630 nm laser. In this manner, the image stored in the singular frame is projected by the 630 nm laser 180 in the even frame. In this way, for the medical practitioner, the veins in the field of view become visible.

The second mode of operation is shown in Figure 32. This mode should be referred to below as the "double buffering mode" (DBM). In the DBM, a second image memory, called image memory 196, is added. In the DBM, the 740 nm laser laser driver for each frame is opened, and in each frame, just as previously described in the AFM mode, the images of the veins are as described in the AFM mode. It is captured and stored in the image memory 191. However, in this case, the electronic block 192 provides an end of the frame indication to both the image memory 196 and the image memory 191 during the blanking time of the raster scan (after completing the The entire image stored in the image memory 191 is transferred to the image memory 196 after the raster scan, but before the start of the next raster scan. During the next frame, the contents of image memory 196 are then projected onto the field of view by the 630 nm laser. In this way, the projected image that is projected is always on the frame behind the actual image being captured. If the frame rate is fast enough, this delay will not become apparent to the practitioner. The MEMS scanner provided herein can easily achieve a frame rate of more than 30 frames per second.

This DBM mode is advantageous as compared to the AFM, where the visible laser is on each frame and therefore has twice the brightness. However, this AFM mode is advantageous in that it only requires a single memory buffer and is therefore more cost effective than the DBM mode.

The third mode of operation is illustrated in Figure 33. This mode should be referred to below as the "instant mode" (RTM). In the RTM, the MEMS 173 is driven in a grating pattern by a MEMS driver 210. The 740 nm laser laser driver 195 is always turned on. The reflected light is received by the 740 nm photodetector 182 and the resulting analog signal is coupled to a laser driver 194 for the 630 nm laser 180. In this manner, the red laser 180 projects the signal in an almost instantaneous manner, the signal being received by the photodetector 182. Only the delay is indicated by the rate of the photodetector and the circuitry of the laser driver 194. Accordingly, there is no need for an image memory buffer and associated digital/analog converters and analog/digital converters. Moreover, since the image system is never stored, there is no need to sense the instantaneous position of the laser, which is used to record the image into the memory or to project the visible image. In fact, in this RTM, the grating pattern does not need to be stable and repeatable like other modes, thereby potentially reducing the complexity and cost of the MEMS and associated driver circuitry.

As such, the RTM is exempt from this scanning pattern, actually utilizing any intensive scanning pattern, such as a two-dimensional moving mirror provided by the Fraunhofer IMPS. In a press release dated January 3, 2005, it describes a two-dimensional mirror as follows: "A laser-based projection device is another option that is advantageous for matrix displays. It requires a modulated laser and a Biasing unit. There are many advantages to using a micro-scanning mirror for performing the deflection of the laser beam in a projection device. In particular, a micro-scanning mirror that operates in a resonant manner in both directions can develop a system with a very small size. High deflection angle with low voltage and low power consumption. The displayed display uses a commercial laser module and a 2D micro-scan mirror, and operates at a bias frequency of 9.4 kHz and 1.4 kHz. The axis is configured to perform a sinusoidal vibration that causes a beam trajectory that describes a Lissajous pattern of high density instead of the normally performed linear scan. Therefore, horizontal and vertical can be used. A low-rate mirror that deflects the frequency. This micro-scanning mirror can be easily fabricated and cost-effective. The control circuit was developed for FPGAs. A resolution of 256x256 monochromatic pixels is provided. A programmable counter is used to generate the mirror drive signal and to determine the position of the beam. The mirror excitation and image synchronization are performed without feedback. Refers to optical or electronic synchronic technology that does not require complication. This simplifies the micro-scanning mirror and control circuitry and can have low production costs. The application of the projection device is display, laser marking, and laser exposure.

In the RTM of Figure 33, the MEMS can be replaced by a two-dimensional mirror of the Fraunhofer IMPS, which establishes a method of high density for establishing raster and other scanned laser patterns.

While many of the specific embodiments described herein utilize a vial holder having an injection needle, there are many other medical procedures that require viewing of such veins. The invention is not limited to devices attached to a vial holder.
