Description

Technical Field

[0001] The invention relates to the technical field of PDA code scanning, in particular to a novel PDA code scanning viewing angle converter. Background Art

[0002] Medical handheld PDA, also known as medical handheld data collector, is a type of data collection, storage and transmission equipment specially designed for scenarios such as mobile medical care, mobile nursing, and medical and patient data management. This type of equipment is usually small in size and easy to carry; it has a flexible operating system; it is equipped with a variety of communication modules, and can be connected to the hospital information system database through various networks. It can be equipped with laser scanning equipment to scan barcodes, collect patient, drug, and material information, and store and query related information. Medical PDA can accurately associate people and objects, optimize the information access process to ensure the accuracy and timeliness of data, and improve the work efficiency of various departments; When the PDA code scanning angle converter is in use, the PDA scans the code on a horizontal plane. When facing scenes such as hanging liquids or placing wrist straps in different body positions, the nurse needs to twist and rotate her wrist to scan the code on a flat surface, which increases the workload of medical staff. At the same time, when the PDA code scanning angle converter is in use, the scanner's built-in sound amplification hole is usually used to generate sound to prompt medical staff, which causes external noise to easily cover the sound of the scanner, making it impossible for medical staff to hear the sound of the scanner in time, affecting the patient's treatment. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a novel PDA code scanning angle converter. Starting a motor can drive a rotating rod and a gear to rotate. Since the gear and the rack are meshingly connected, the gear can mesh with the surface of the gear when rotating. The meshing movement of the gear can drive the mounting seat to slide on the surface of the slide rail. Since the slide rail is in a semicircular shape, the mounting seat can slide in a semicircular shape on the surface of the slide rail. The slide rail is matched with the patient's hand strap ring. When the slide rail moves to a specified position, the first micro-electric push rod is started so that it can drive the movable plate and the camera to extend and retract together, so that the length of the camera can be adjusted. The second micro-electric push rod is started so that one side of the movable plate can be pushed backward so that the movable plate can drive the camera to tilt and swing. When the movable plate is tilted, the other side of the movable plate can drive the second movable rod to tilt, so that the first movable rod and the second movable rod can support the tilt of the movable plate. The first micro-electric push rod and the second micro-electric push rod are used to adjust the length and orientation of the camera. The sliding of the slide plate ensures that the code can be scanned accurately and quickly at different angles. When the barcode scanner sounds an alarm, the first metal sheet and the second metal sheet are relatively thin and are affected by the sound waves of the barcode scanner and vibrate. The vibration of the first metal sheet can cause the spring to drive the connecting plate to shake. The shaking of the connecting plate can cause the first metal sheet to drive the first bell cover to move and collide with the second bell cover to produce a sound. The first bell cover and the second bell cover can increase the sound of the scanner alarm, thereby improving the reminder effect of the scanner and solving the problems of limited scanning angle and low sound.

[0014] Compared with the prior art, the present invention provides a new PDA code scanning viewing angle converter, which has the following beneficial effects: 1. The present invention starts a motor to drive the rotating rod and the gear to rotate. Since the gear and the rack are meshingly connected, the gear can mesh with the surface of the gear when rotating. The meshing movement of the gear allows the slide plate to drive the mounting seat to slide on the surface of the slide rail. Since the slide rail is in a semicircular shape, the mounting seat can slide in a semicircular shape on the surface of the slide rail, and the slide rail is matched with the patient's hand strap ring. When the slide plate moves to a specified position, the first micro-electric push rod is started so that it can drive the movable plate and the camera to extend and retract together, so that the length of the camera can be adjusted. The second micro-electric push rod is started so that it can push one side of the movable plate backward so that the movable plate can drive the camera to tilt and swing. When the movable plate is tilted, the other side of the movable plate can drive the second movable rod to tilt, so that the first movable rod and the second movable rod can support the tilt of the movable plate. The first micro-electric push rod and the second micro-electric push rod are used to adjust the length and orientation of the camera, and cooperate with the sliding of the slide plate to ensure that the code scanning can be completed accurately and quickly at different angles.

[0015] 2. In the present invention, when the barcode scanner sounds an alarm, the first metal sheet and the second metal sheet are thinner and thus can vibrate under the influence of the sound waves of the barcode scanner. The vibration of the first metal sheet can cause the spring to drive the connecting plate to shake. The shaking of the connecting plate can cause the first metal sheet to drive the first bell cover to move and collide with the second bell cover to produce a sound. The first bell cover and the second bell cover can increase the sound of the scanner alarm, thereby improving the reminder effect of the scanner.

[0016] 3. In the production of barcode labeling detection, the PDA of the present invention can quickly read the barcode information on the product and compare it with the standard data in the system. If the barcode information does not match, the PDA will issue a prompt in time to facilitate the staff to find errors in time. According to its alarm mode, we can set the "infusion time alarm function and patrol time alarm function". When the liquid is started to be infused, the code is scanned as the start time and the number of drops is displayed. We preset different alarm times according to the milliliters of the liquid, which serves as an early warning mode. The advantages of this are, first, reminding the staff that the patient's liquid is about to end, second, it is for hospitalized patients without a caregiver or patients who cannot see the liquid after ophthalmic surgery to know in advance, and third, when a patient has multiple bottles of liquid, it can know when the next group will be prepared, and there will be no expiration. As for the patrol time, the nurse can set it according to the total milliliters of liquid or time to prevent the patrol from being ignored due to busy work and unnecessary intravenous therapy errors.

The vibration of the first metal sheet 22 can make the spring 20 drive the connecting plate 21 to shake. The shaking of the connecting plate 21 can make the first metal sheet 22 drive the first bell cover 25 to move and collide with the second bell cover 24 to produce a sound. The first bell cover 25 and the second bell cover 24 can increase the sound of the scanner alarm, thereby improving the reminder effect of the scanner.

[0022] The PDA code scanning system includes a camera entry module, an information reading module, an information comparison module, an alarm prompt module, an infusion time module, a dripping module, a timing module, a patrol time alarm module, and an infusion alarm module, and the camera entry module, the information reading module, the information comparison module, the alarm prompt module, the infusion time module, the dripping module, the timing module, the patrol time alarm module, and the infusion alarm module are all electrically connected to the PDA code scanning system.

If the barcode information does not match, the PDA will issue a prompt in time to facilitate the staff to find errors in time. According to its alarm mode, we can set the "infusion time alarm function and inspection time alarm function". When the liquid is started to be infused, the code is scanned for the start time and the number of drops is displayed. We preset different alarm times according to different milliliters of liquid to play an early warning mode. The benefits of this are that, first, it reminds the staff that the patient's liquid is about to end, second, it is for hospitalized patients who have no care or patients who cannot see the liquid after ophthalmology surgery to know in advance, and third, when a patient has multiple bottles of liquid, they can know when to prepare the next group, and there will be no expiration. As for the inspection time, the nurse can set it according to the total milliliters of liquid or time to prevent the busy work from neglecting the inspection and causing unnecessary intravenous therapy errors.

[0023] When in use, when the device scans the barcode on the surface of the patient's wristband, the motor 8 is started to drive the rotating rod 9 and the gear 10 to rotate. Since the gear 10 is meshed with the rack 11, the gear 10 can mesh with the surface of the gear 10 when rotating. The meshing movement of the gear 10 allows the slide plate 4 to drive the mounting seat 14 to slide on the surface of the slide rail 2. Since the slide rail 2 is semicircular, the mounting seat 14 can slide in a semicircular shape on the surface of the slide rail 2.

The first micro-electric push rod 13 and the second micro-electric push rod 12 are used to adjust the length and orientation of the camera 18. Since the thickness of the first metal sheet 22 and the second metal sheet 23 is relatively thin, they can be affected by the sound waves of the barcode scanner 1. Vibration occurs, and the vibration of the first metal sheet 22 is used to make the spring 20 drive the connecting plate 21 to shake. The shaking of the connecting plate 21 is used to make the first metal sheet 22 drive the first bell cover 25 to move and collide with the second bell cover 24 to produce a sound. The first bell cover 25 and the second bell cover 24 can increase the sound of the scanner alarm. In the production barcode labeling detection, the PDA can quickly read the barcode information on the product and compare it with the standard data in the system. If the barcode information does not match, the PDA will issue a prompt in time, so that the staff can find the error in time. According to its alarm mode, we can Set up the "infusion time alarm function and patrol time alarm function". When starting to infuse the liquid, scan the code for the start time and display the number of drops. We preset different alarm times according to the milliliters of the liquid, which serves as an early warning mode. The advantages of this are: first, remind the staff that the patient's liquid is about to end; second, it is for hospitalized patients without a caregiver or postoperative ophthalmic patients who cannot see the liquid to know in advance; third, when a patient has multiple bottles of liquid, they can know when the next set will be prepared, and there will be no expiration. As for the patrol time, the nurse can set it according to the total milliliters of liquid or time to prevent the staff from ignoring patrols due to busy work and making unnecessary intravenous therapy errors.
