2. Description of the Related Art
The prior art of patent number M242181 of Taiwan patent discloses a data storage device integrated with various medical measurement devices, which includes a housing and a controller unit. The controller unit installed in the housing is used to control the operations of the various units. A transmission unit connected to the controller unit via an electrical wire is used to receive data from an external measurement device and send the data to the controller unit. A data storage unit, connected to the controller unit electrically, is used to store the data received from the transmission unit. A display unit is connected to a controller unit electrically, and is used to display data. A calculation unit is used to process and compare data with the expected value advised by a doctor. A warning unit connected to the controller unit electrically is used to send out an alarm signal.
In the prior art, the data storage device integrated with the various medical measurement devices can not identify data from the different patients efficiently. When a medical attendant takes a plurality of patients' physiological data values, he or she must distinguish the patients by manually controlling the medical measurement device. Alternatively, the medical attendant can take note and record every patient's measurement results on paper, and then input the results into a computer of the nursing station. Both ways mentioned above are very time-consuming and error prone.
Therefore, the present invention provides an integrated medical measurement system utilizing infrared transmission to overcome the shortcoming of the prior art.
A primary objective of the present invention is to disclose an integrated medical measurement system utilizing infrared transmission. The restriction of distance and direction of infrared transmission allows the signal not to be interfered. The infrared transmission has the advantage of convenience of wireless transmission but doesn't exist the shortcoming of mutual interference of the wireless transmission.
Further, a barcode scanner is utilized to verify patients' and operators' identifications, and a first infrared transmission device is utilized to receive the data and the patients' physiological data values from a second measurement device. Both kinds of the above mentioned data are stored in a medical record device. A USB slot is utilized to connect the medical record device with a computer in a nursing station.
Also, the computer in the nursing station is connected with a Hospital Information System (HIS) or a Laboratory Information System (LIS) through TCP/IP, such that, the data related to the patients can be fully utilized.
To achieve the above mentioned objective, the present invention provides an integrated medical measurement system utilizing infrared transmission, which comprises a medical record device and a plurality of barcodes. The medical record device comprises a microprocessor connected to a barcode scanner. The barcode scanner is used to scan the identification barcodes worn on the patients and the operators. A first measurement device connected to the microprocessor is utilized to detect every patient's physiological data values. A first infrared transmission device is connected to the microprocessor for receiving data from the second measurement device. In the present invention, barcode scanner is used to verify the identity of a patient, and the first infrared transmission device can receive the data and the patients' physiological data values transmitted from the second measurement device. The above mentioned data is stored in the medical record device, which is connected with a computer in a nursing station through a USB slot. The characteristic of the infrared transmission is that its distance and direction can be restricted, thus avoiding the signal interference or the transmission error. Also, the computer in the nursing station is connected with a Hospital Information system or a Laboratory Information System through TCP/IP, such that data related to the patients can be fully utilized.
It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.

A power system 44 located between the USB slot 36 and the microprocessor 22 comprises a battery recharge circuitry 46, a rechargeable battery 48, a DC/DC boost converter 50, a 5V/3.3V converter 52 and a battery voltage detect circuitry 54. The two ends of the battery recharge circuitry 46 are connected respectively with the USB slot 36 and the rechargeable battery 48; the two ends of the DC/DC boost converter 50 are connected respectively with the rechargeable battery 48 and the 5V/3.3V converter 52; the other end of the 5V/3.3V converter 52 is connected to the microprocessor 22; the battery voltage detect circuitry 54 is located between the rechargeable battery 48 and the microprocessor 22. The power system 44 recharged through the USB slot 36 supplies the medical record device 12 with the electrical power. The rechargeable battery 48 can be a lithium battery.
A first infrared transmission device 56 is connected with a microprocessor 22. A first measurement device 58 connected with a microprocessor 22 is used to detect the physiological data values of the patients. In one embodiment of the present invention, the first measurement device 58 in
At least one second measurement device 66 located outside the medical record device 12 comprises a second infrared transmission device 68. By connecting the medical record device 12 with the second infrared transmission device 68 electrically through a first infrared transmission device 56, the medical record device 12 receives the data from the second measurement device 66. The above mentioned data is stored temporarily in the medical record device 12, and then the data is sent to a computer 14 in the nursing station through the USB slot 36. The second measurement device 66 can also be a kind of device capable of detecting the physiological data values, such as a thermometer, a blood pressure meter, a blood glucose meter, an oximeter, a pulsimeter, a weight scale, or a body fat meter.
According to the differences of the above mentioned measurement devices, the physiological data value could be a blood pressure value, a body temperature value, a blood glucose value, a blood oxygen value, a pulse value, a weight value or a body fat value.
In the embodiment of the present invention, the first measurement device 58 is the blood glucose meter including a blood glucose test strip slot 60, a test strip sensor 62, and an amplifier 64. The blood glucose test strip is detected by the test strip sensor 62 through the blood glucose test strip slot 60. The signal of the blood glucose is transmitted to the microprocessor 22 after the signal is amplified by the amplifier 64. The blood glucose value of patient A obtained through calculation is stored into the memory module 32.

Because the barcode scanner 24 has scanned/inputted the data of the patient while, and the medical record device 12 has recorded the patient's data and time of recording the data, the medical attendant only needs to input another physiological data value acquired from the second measurement device 66. Compared with the prior art, the different patients are distinguished by controlling the medical measurement device manually or taking a note with a paper, the embodiment of the present invention is more convenient and has lower error possibilities.
The medical record device 12 is able to record the data of a plurality of the patients. The medical attendant can use the USB slot 36 to output the data into the computer 14 in the nursing station. The computer 14 is connected to a Hospital Information System (HIS) 16 or a Laboratory Information System (LIS) 18 through TCP/IP.
The barcode scanner 24 is utilized to identify the identifications of the patients according to one embodiment of the present invention. The first measurement device 58 (the blood glucose meter) is utilized to detect the blood glucose value of the patient. The first infrared transmission device 56 is connected wirelessly with the second infrared transmission device 68 of the second measurement device, such that the medical record device 12 can receive the data from the second measurement device 66, and the data can be stored in the medical record device 12, and that is connected to a computer 14 in a nursing station through a USB slot 36. Due to the characteristic of the infrared transmission, the restrictions of its distance and direction ensure that signal will not be interfered. Also, TCP/IP is utilized to transmit data from the computer 14 in the nursing station to the Hospital Information System 16 or the Laboratory Information System 18, such that the data related to the patients can be fully utilized.
