Description

Patient diagnosis apparatus which has a moving display for patient

The present invention effectively delivers diagnostic information to patients when ultrasound diagnosis, oral examination and treatment, and other areas of the patient's field of vision that are difficult to reach, or desires for desired information even in a comfortable and comfortable posture to appease patients' hospitality. The present invention relates to a monitor transfer device having a display for screening or related image information and moving to an inner range of the patient's field of view in various diagnostic postures so that the patient can see the screen in a comfortable posture.

(Background 1) Recently, the thin and small size of display, which is represented by LCD, is progressing rapidly. While the most commonly used family of CRT monitors weighed in at least 30 kg and had a volume of more than 0.2 m 3, the flagship monitors of today's flat panel monitors are only a few weights and tens of volumes. Some consumers want to attach multiple flat panel monitors to the wall, to the ceiling, or even to hang them in the air. However, even in the case of light and thin flat panel monitors, it is not easy to move and reattach them easily in any fixed position by any direction and distance whenever the user wants, especially simple structure and reliable design that can be commercialized and sold at a realistic price. Monitor shifters with remote control are still hard to find.

(Background 2) It is a basic desire of patients to see the diagnosis result on the real time screen or to see the specific treatment process on the real time screen. Representative ultrasonography, a diagnostic test that is currently widely used, can provide diagnostic images generated in real time in a wide variety of affected areas, including the abdomen, pelvis, thyroid, breast, limb and neck vessels, prostate, and testes. Of course, at this time, it is natural that the patient must take a certain posture in order to acquire an ultrasound image of a specific site, and the viewing angle of the patient is very limited in this process.

Severe inpatients who lie in bed and are unable to move for long periods of time, or those who have oral or otolaryngology treatments, also have a basic desire to see video images that fit their vision in a comfortable position. In most cases, however, the cost of equipment or equipment to meet those needs is in any way a burden on the patient, the consumer. Therefore, these patient-friendly imaging devices must be able to be produced and sold within a range of realistic costs, and must also have a simple, intuitive, mechanically superior mechanism, commercially superior manufacturing cost, and emotional quality to induce a consumer's purchase.

Currently, monitors for displays are very light and thin, and will be lighter, thinner and bendable or bent in the future. However, even light and thin monitors weigh at least a few kilograms, so it is natural to have a separate mechanical transfer mechanism to move them according to the patient's field of view.

The first conceivable mechanical transport mechanism is a form of motion similar to that of most production robots. In other words, it can be designed as a structure that operates by interlocking a monitor with a robotic transfer device equipped with a rotary pedestal and having a polyarticular moving arm similar to a human arm and linking it with information transmitted from diagnostic or inspection equipment. have.

However, the robotic arm is basically a method of transferring the rotational movement based on the polar coordinate system to the desired position by continuously overlapping the triple or quadruple, so that the weight of the conveying object as well as its own weight of the metal arm and its combination It requires complex motion control considering the weight of the object and the inertia generated when the joint is rotated. Therefore, most robotic arm devices must be equipped with a large number of precision feed motors, which is of course expensive, bulky, and require careful management.

Next, there is a method of simply attaching and fixing a display device on a ceiling or a wall. This method is suitable for temporary installations, and a dedicated mount can be easily manufactured at low cost. However, since the position is fixed, the patient's field of view must be constant or fixed to see comfort. Therefore, it is difficult to have more value than a wall-mounted TV, and in particular, it is difficult to use as a diagnostic aid. For example, if you look at the ultrasound, there is a huge difference in the field of vision between the ultrasound, which requires you to tilt your neck, such as the thyroid gland, and the ultrasound, such as your pelvis or prostate, where your head is naturally bowed down. Cannot solve this situation at all.

According to the present invention, the necessity has been raised steadily, but in the portable display device for a patient, which has not been attempted due to lack of reality in terms of cost-effectiveness, a simple and excellent design, suitable production cost, excellent emotional quality, and high It combines the transfer performance and the operation reliability, and is concretely implemented to the extent that it is commercially available.

The patient display device and the patient diagnosis device comprising the same of the present invention solve the conventional problems with the following technical focus.

First, it was noted that most of the patient's field of view moves long in the longitudinal direction along the direction in which the patient lies (in the present invention, defined as the longitudinal direction as the direction coinciding with the spine direction). The human eye basically has a narrow up and down view, and a wide left and right view. Therefore, when looking at a particular object, most people feel uncomfortable in situations where the neck needs to be flipped up and down (the eyes must be raised or lowered up and down). It is worth making a device. On the other hand, it is not so inconvenient to see the neck and the eyes turning slightly from side to side together, so it is not worth to implement kinematically. Therefore, in the present invention, the longitudinal carriage 10 having a long stroke in the longitudinal direction is arranged longitudinally on the space in which the patient is lying, and combines the transfer device 20 moving along the field of view of the patient, and then to the transfer device. The monitor 30 which displays the image information specialized for a patient was arrange | positioned. In this way, most of the patient's field of view can be covered only by the movement in the front-rear direction (one direction) of the transfer device, that is, the longitudinal movement based on the patient's field of view.

Next, the conveyance path of the longitudinal conveyance table 10, ie, the trajectory of the conveyance rail 23, was configured as a curve. When viewed from the side, it shows a conveying path that seems to ride over a bent valley, and the design of the drive unit of the conveying device 20 is frequently located at both ends and center points, even if it is not accompanied by an expensive precision control device equivalent to the production robot of the factory. It makes it possible to move and stop the feeder easily and reliably at the desired angle at the point. As a typical effect of the curve trajectory, since the curve movement is accompanied by the change of the monitor angle, there is an additional design improvement effect to omit one driving module required for adjusting the tilt angle of the monitor. In addition, the curved path of the longitudinal carriage is curved to more than one stage so that the monitor can be stabilized at the initial position naturally by its own weight at the bottom of the center. This is an important track stabilization structure that is essential in the case of manual feeding, and has the advantage of not having to introduce expensive feed control mechanisms such as a precise feed motor and a complicated braking device that can be stopped at a precise position.

In addition, the present invention introduces a configuration of a horizontal feeder 11 capable of transferring the monitor 30 in the horizontal or vertical direction in designing the transfer device 20. The transverse carriage is also curved in a similar way to the longitudinal carriage, and the support point can be rotated slightly as needed. The monitor's horizontal movement along the curved transfer path and the monitor's shangdong, which reflects the natural deflection due to the monitor's weight, give the effect as if the monitor is wrapping around the patient. When limited to a few places, such as, the extremely simple transfer structure and low-cost transfer control mechanism make it easy to move and stop the monitor in at least nine positions. This number of selectable locations is not exactly in the center of the patient's field of view, but given that the space in which the patient is lying, such as a bed, is very limited, the position and head angle of the patient are also limited. This corresponds to the monitor transfer range that can cover.

The present invention is very simple in structure and can provide a quick and appropriate display of 100% view into the field of view in virtually any position a patient can take. Therefore, the patient can receive differentiated high-quality medical services in a comfortable posture for a long time, and can comfortably view various image contents even during a break, waiting for a hospital, or a severe hospitalization. In addition, the present invention does not have a complex robot arm type, but moves along a trajectory suspended in the air, but it may seem complicated at first. However, the present invention can be designed to reciprocate only a few points such as an initial position, an intermediate position, and an end point by its own weight. Therefore, most of the patient diagnosis apparatus accompanied with the image information such as the ultrasonic inspection device can be easily added at a very low cost and can be introduced economically enough in a place where expensive equipment such as an inpatient room is difficult to enter.

With reference to the embodiments of the present invention included in the drawings in order to technically support the above-mentioned solution of the present invention will be described in detail.

However, in the following embodiments, the components including the specific terminology and combinations thereof do not limit the technical spirit inherent in the present invention.

1 to 7 is a view showing a specific shape of the present invention for the patient mobile display device and the fixed embodiment.

Briefly dividing the configuration of each part of the mobile display device shown, the longitudinal carriage 10 is largely disposed on the space in which the patient is lying, and the transfer apparatus 20 coupled to the longitudinal carriage 10 and moved in accordance with the patient's field of view And a monitor 30 coupled to the transfer device 20 to display image information to the patient, and a data communication unit 40 to transfer the image information to the monitor 30, and a transfer control unit 22 which may be further provided. Can be divided into

In order to place the longitudinal carriage 10 in the space above the patient, a movable or stationary support 12 is added which can stand on its own or can be fixed to a patient bed or attached to a building. The support 12 can be flipped up to allow the patient to lie down and get up as shown in FIG. 4. In this process, it is preferable that the gas pressure lifter 13, which has a buffering action and a weight supporting action, is installed at the bent portion of the support. The load supported by the support is about 50 ~ 70kg or less, including 2 carriages, motor, gear, etc., based on the standard 15 ~ 22 inch small and medium size LCD monitor mounting standard. It is only 2-3 times. Therefore, the present mobile display device can be easily lifted and lowered by human force with the help of a gas pressure lifter 13 similar to the hood lifter of a passenger sedan.

The longitudinal carriage 10 directly coupled to the support 12 serves as a support for the load of all driving elements that are transported as the most central structure corresponding to the spine of the present invention. In the present embodiment, the horizontal-vertical trajectory of the trajectory is superimposed at the upper end point where the patient can cover the patient's field of view when the patient is lying down and leans up. Even with the head down, there is a long round-trip distance that covers virtually all of the patient's upper and lower vision up to the lower end so that they still have good visibility. In addition, considering the fact that the transverse carriage 10 is slightly bent down to induce a natural angle change of the monitor 30 according to the patient's field of view, the monitor may be placed on a certain spherical surface beyond the simple nine points. It is possible to perform the movement included up to the inclination angle of the monitor in a close form. That is, a simple design without adding a separate monitor tilt angle controller can realize a natural tilt angle.

On the other hand, although not shown separately in the drawing, it is possible to add a simple latching device that does not leave the feed rail when the feeder is inclined at both ends of the vertical feeder, or by designing the rail itself magnetically so that the transport wheel does not fall off the surface of the rail. By taking measures, the monitor can be tilted too much to avoid the risk of the transfer unit leaving the transfer rail. In addition, if you look closely at the curved shape of the vertical transfer table 10 as described above, it can be seen that the central portion is concave down, which is curved in a multi-stage curved feed rail 23 to induce the initial position stability of the transfer device 20. The result is. At the lower concave point of the center the conveying device can be stabilized. Therefore, suppose that the transfer device 20 is moved to only three points of the center (initial position) and left and right transfer end points. In this case, the transfer control may be completed by only one conventional synchronous motor synchronized with the power frequency. This means that you do not have to have a precise step motor, or a precision motor with integrated brakes, or an integral rotational system, which is required for normal robot arm operation. Therefore, the apparatus in the present embodiment can be significantly reduced manufacturing cost, and can be fully operated even by a fully manual push and pull method by the initial position stable structure. In this case, as well as the weight and manufacturing cost is greatly reduced, it can be an entertainment device that can be installed for each bed of a large ward.

For reference, the conveying rail 23 and the conveying wheels (wheels rolling on the rail) included in the conveying device 20 are not shown separately by reference numerals or the shape of the track surface, but the teeth are similar to the rack-pinion gear combination. Of course, it can be simply manufactured with a well-known tool such as a mold or a chain-sprocket combination structure is widely commercially available in the art, and there is little consideration in the process except for cost. Of course, it is also possible to have a simple sliding groove and wheel structure as shown, in this case, to prevent the departure of the track by the magnetic force or by attaching a horizontal transfer table 11 to be described below closely attached to the fundamental device to prevent the departure of the track Can be.

As a simplified example of the overall structure, the transverse carriage 11 intentionally shown in the present embodiment will be described in detail in this embodiment. The horizontal conveyer 11 is a member having a conveying rail 23 added in the horizontal direction so that the monitor 30 can be conveyed in the horizontal or vertical direction separately from the conveying device 20 which performs the conveying action only in the vertical direction. to be. In this embodiment, the position where most of the driving unit is actually fixed, such as the feeder 20 including the reduction gear and the feed wheel, and the feed motor 21 for driving the same, is the upper surface of one side of the horizontal feeder. Was offset by fixing the transfer control unit 22 and the data communication unit 40 attached to the monitor 30 disposed at the lower side on the opposite side, and to maintain the left and right weight balance as a whole. This is a design that overcomes the structural limitation that the transport device 20 can only access to one side of the longitudinal carriage 10 because of the support 12. The cable connection that can be complicated by the control unit placed on the monitor is wired and wireless. It can be overcome by mixing appropriately.

On the other hand, the hand-operated horizontal feeder 11 and the monitor 30 are provided with a movable handle 31, respectively. The user of the device, including a doctor and a patient, can easily move the monitor to a desired position by pushing the cart while holding the movable handle. Can be. The mobile handle 31 is an essential component in another embodiment of the present invention, which can be designed to be fully automatic, in order to prepare for a temporary failure or a data communication failure and to guarantee a more free transfer according to the user's taste. The manufacturer needs to design a device that omits the motor drive as much as possible considering the attachment position and the operation direction of the movement handle.

It looks at the progress of the vertical transfer shown to be made automatically in this embodiment.

First, image information and transfer information are transferred from the third external device (whether it is a patient inspection device or a TV remote control in the inpatient's hand) to the data communication unit 40, and the data communication unit is transferred to the transfer control unit 22. If the transfer or integrated communication control unit it is possible to directly control the transfer amount of the transfer device 20 by the transfer information. Of course, the data communication unit 40 is capable of both wired and wireless communication. In this embodiment, the cable is removed in order to prevent unnecessary confusion, but a simple pulley (pulle) is installed on the vertical carriage and the horizontal carriage and wired communication is also possible by installing an automatic winding / unlocking device.

8 to 10 illustrate a patient diagnosis device and a specific operating embodiment in which a mobile display device of the present invention, a bed on which the device is mounted, and an ultrasound examination device beside a bed are combined.

A patient diagnosis device having a mobile display device for a patient does not need to be designed exclusively and can be compatible with a simple communication device and a control program on an existing test device. This is because the process of converting the diagnosis information of the patient into image information and transmitting the short-range wireless or wired communication to the data communication unit 40 can be performed without redesigning the system.

For example, as shown in FIG. 8, a case in which an additional communication device for transmitting image information and inspection mode information to the data communication unit 40 is selected as a conventional ultrasonic inspection device. When the examiner (doctor) selects a specific probe and determines a specific inspection site, the additional communication device of the ultrasound inspection apparatus transmits the visual field information and the ultrasound image information of the patient to the data communication unit 40 wirelessly or wirelessly. Can transmit The data communication unit 40 receives the information and sends the image information to the monitor 30, and the current visual field information of the patient according to the examination position of the ultrasound probe is converted into suitable transport information so that the transport device 20, more specifically, Can be transferred to the feed control unit 22. Therefore, the patient only needs to take a specific test posture according to the doctor's instructions, and the doctor only needs to operate the test apparatus. Of course, you can also manually move the monitor by model or in certain operating modes.

All information communication and signal processing processes, including wired and wireless communication involved in the automatic transfer process and data conversion and data retransmission after data classification involved in the image information sharing process, correspond to the technical gist of the present invention. It is noted that the present invention is extremely common in current IT technology, and thus is in accordance with the conventional level of implementation in the art.

For example, the vertical upper end transfer of FIG. 9 will be described as an example. For example, in a thyroid ultrasonography, when the patient tilts the neck upward and the doctor places the thyroid test probe on the neck, the patient's field of view is naturally upward. In this state, it is natural that the patient would like to see a doctor while looking at the screen comfortably. Therefore, in order to share the inspection screen generated by the ultrasonic inspection apparatus to the monitor 30, in the process of transmitting the information can be shot separately the transfer information in front of the signal processing. Receiving this information communication device 40 sends the transfer information to the transfer control unit 22 and then displays the image information transmitted on the monitor. This process can be performed using a general serial cable or a conventional D-sub or HDMI cable, and can also be performed by wireless data transmission in accordance with general WLAN protocol.

Look at the vertical bottom end transfer of FIG. Looking at the drawing, you can see that the monitor has also moved horizontally (far from the picture). When the patient leans sideways while lying sideways, the gaze naturally comes down to the side. In this case, the vertical movement is automatically performed in the downward direction, and in the present embodiment, since the horizontal direction is a manual operation method, the doctor can easily and quickly move to a screen position where the patient is comfortable by simply pushing the moving handle. In this process, since the horizontal carriage 10 is also a curved shape, not only horizontal movement but also natural up-and-down movement, and further, three-dimensional tilt angle adjustment of the monitor is also possible (see FIG. 10).

One embodiment of the present invention has been described in detail with reference to the drawings, but the technical idea of the present invention is not limited to the above embodiment.

In other words, those of ordinary skill in the art to which the present invention pertains can utilize the technical spirit contained in the specification and drawings of the present invention, and, if necessary, simply change and simplify the description and drawings of the present invention. Although extended examples may be implemented, these are also clearly included in the scope of the present invention as expressed by the following claims.

The mobile display device of the present invention can be extremely useful in the elderly hospitals or most nursing hospitals as well as the auxiliary means of various inspection devices, and when combined with an appropriate self-supporting columnar support, can be used for various purposes regardless of the place. .

In addition, it will be possible to manufacture a synthetic frame instead of a metal beam in accordance with the development of near field communication, high-capacity high-speed data transmission technology, and accelerated monitor thickness and weight reduction speed. It can be seen that the present invention includes the possibility of being used as an expensive learning aid.
